The present disclosure relates to a cartridge for aerosol delivery devices such as electronic cigarettes, and more particularly to methods for assembling a cartridge for aerosol delivery devices including an atomizer, and associated systems and apparatuses. The atomizer may be configured to heat an aerosol precursor, which may be made or derived from tobacco or otherwise incorporate tobacco, to form an inhalable substance for human consumption.
Many smoking devices have been proposed through the years as improvements upon, or alternatives to, smoking products that require combusting tobacco for use. Many of those devices purportedly have been designed to provide the sensations associated with cigarette, cigar, or pipe smoking, but without delivering considerable quantities of incomplete combustion and pyrolysis products that result from the burning of tobacco. To this end, there have been proposed numerous smoking products, flavor generators, and medicinal inhalers that utilize electrical energy to vaporize or heat a volatile material, or attempt to provide the sensations of cigarette, cigar, or pipe smoking without burning tobacco to a significant degree. See, for example, the various alternative smoking articles, aerosol delivery devices and heat generating sources set forth in the background art described in U.S. Pat. No. 8,881,737 to Collett et al., U.S. Pat. App. Pub. No. 2013/0255702 to Griffith Jr. et al., U.S. Pat. App. Pub. No. 2014/0000638 to Sebastian et al., U.S. Pat. App. Pub. No. 2014/0096781 to Sears et al., U.S. Pat. App. Pub. No. 2014/0096782 to Ampolini et al., and U.S. patent application Ser. No. 14/011,992 to Davis et al., filed Aug. 28, 2013, which are incorporated herein by reference in their entireties.

These and other features, aspects, and advantages of the disclosure will be apparent from a reading of the following detailed description together with the accompanying drawings, which are briefly described below. The invention includes any combination of two, three, four, or more of the above-noted embodiments as well as combinations of any two, three, four, or more features or elements set forth in this disclosure, regardless of whether such features or elements are expressly combined in a specific embodiment description herein. This disclosure is intended to be read holistically such that any separable features or elements of the disclosed invention, in any of its various aspects and embodiments, should be viewed as intended to be combinable unless the context clearly dictates otherwise.
Having thus described the disclosure in the foregoing general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present disclosure will now be described more fully hereinafter with reference to exemplary embodiments thereof. These exemplary embodiments are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in the specification, and in the appended claims, the singular forms “a”, “an”, “the”, include plural variations unless the context clearly dictates otherwise.
The present disclosure provides descriptions of systems for assembling aerosol delivery devices. The aerosol delivery devices may use electrical energy to heat a material (preferably without combusting the material to any significant degree) to form an inhalable substance; such articles most preferably being sufficiently compact to be considered “hand-held” devices. An aerosol delivery device may provide some or all of the sensations (e.g., inhalation and exhalation rituals, types of tastes or flavors, organoleptic effects, physical feel, use rituals, visual cues such as those provided by visible aerosol, and the like) of smoking a cigarette, cigar, or pipe, without any substantial degree of combustion of any component of that article or device. The aerosol delivery device may not produce smoke in the sense of the aerosol resulting from by-products of combustion or pyrolysis of tobacco, but rather, that the article or device most preferably yields vapors (including vapors within aerosols that can be considered to be visible aerosols that might be considered to be described as smoke-like) resulting from volatilization or vaporization of certain components of the article or device, although in other embodiments the aerosol may not be visible. In highly preferred embodiments, aerosol delivery devices may incorporate tobacco and/or components derived from tobacco. As such, the aerosol delivery device can be characterized as an electronic smoking article such as an electronic cigarette or “e-cigarette.”
While the systems are generally described herein in terms of embodiments associated with aerosol delivery devices such as so-called “e-cigarettes,” it should be understood that the mechanisms, components, features, and methods may be embodied in many different forms and associated with a variety of articles. For example, the description provided herein may be employed in conjunction with embodiments of traditional smoking articles (e.g., cigarettes, cigars, pipes, etc.), heat-not-burn cigarettes, and related packaging for any of the products disclosed herein. Accordingly, it should be understood that the description of the mechanisms, components, features, and methods disclosed herein are discussed in terms of embodiments relating to aerosol delivery mechanisms by way of example only, and may be embodied and used in various other products and methods.
Aerosol delivery devices of the present disclosure also can be characterized as being vapor-producing articles or medicament delivery articles. Thus, such articles or devices can be adapted so as to provide one or more substances (e.g., flavors and/or pharmaceutical active ingredients) in an inhalable form or state. For example, inhalable substances can be substantially in the form of a vapor (i.e., a substance that is in the gas phase at a temperature lower than its critical point). Alternatively, inhalable substances can be in the form of an aerosol (i.e., a suspension of fine solid particles or liquid droplets in a gas). For purposes of simplicity, the term “aerosol” as used herein is meant to include vapors, gases and aerosols of a form or type suitable for human inhalation, whether or not visible, and whether or not of a form that might be considered to be smoke-like.
In use, aerosol delivery devices of the present disclosure may be subjected to many of the physical actions employed by an individual in using a traditional type of smoking article (e.g., a cigarette, cigar or pipe that is employed by lighting and inhaling tobacco). For example, the user of an aerosol delivery device of the present disclosure can hold that article much like a traditional type of smoking article, draw on one end of that article for inhalation of aerosol produced by that article, take puffs at selected intervals of time, etc.
Smoking articles of the present disclosure generally include a number of components provided within an outer shell or body. The overall design of the outer shell or body can vary, and the format or configuration of the outer body that can define the overall size and shape of the smoking article can vary. Typically, an elongated body resembling the shape of a cigarette or cigar can be a formed from a single, unitary shell; or the elongated body can be formed of two or more separable pieces. For example, a smoking article can comprise an elongated shell or body that can be substantially tubular in shape and, as such, resemble the shape of a conventional cigarette or cigar. In one embodiment, all of the components of the smoking article are contained within one outer body or shell. Alternatively, a smoking article can comprise two or more shells that are joined and are separable. For example, a smoking article can possess at one end a control body comprising a shell containing one or more reusable components (e.g., a rechargeable battery and various electronics for controlling the operation of that article), and at the other end and removably attached thereto a shell containing a disposable portion (e.g., a disposable flavor-containing cartridge). More specific formats, configurations and arrangements of components within the single shell type of unit or within a multi-piece separable shell type of unit will be evident in light of the further disclosure provided herein. Additionally, various smoking article designs and component arrangements can be appreciated upon consideration of the commercially available electronic smoking articles.
Aerosol delivery devices of the present disclosure most preferably comprise some combination of a power source (i.e., an electrical power source), at least one control component (e.g., means for actuating, controlling, regulating and/or ceasing power for heat generation, such as by controlling electrical current flow from the power source to other components of the aerosol delivery device), a heater or heat generation component (e.g., an electrical resistance heating element or component commonly referred to as part of an “atomizer”), and an aerosol precursor composition (e.g., commonly a liquid capable of yielding an aerosol upon application of sufficient heat, such as ingredients commonly referred to as “smoke juice,” “e-liquid” and “e-juice”), and a mouthend region or tip for allowing draw upon the aerosol delivery device for aerosol inhalation (e.g., a defined air flow path through the article such that aerosol generated can be withdrawn therefrom upon draw).
Alignment of the components within the aerosol delivery device of the present disclosure can vary. In specific embodiments, the aerosol precursor composition can be located near an end of the aerosol delivery device which may be configured to be positioned proximal to the mouth of a user so as to maximize aerosol delivery to the user. Other configurations, however, are not excluded. Generally, the heating element can be positioned sufficiently near the aerosol precursor composition so that heat from the heating element can volatilize the aerosol precursor (as well as one or more flavorants, medicaments, or the like that may likewise be provided for delivery to a user) and form an aerosol for delivery to the user. When the heating element heats the aerosol precursor composition, an aerosol is formed, released, or generated in a physical form suitable for inhalation by a consumer. It should be noted that the foregoing terms are meant to be interchangeable such that reference to release, releasing, releases, or released includes form or generate, forming or generating, forms or generates, and formed or generated. Specifically, an inhalable substance is released in the form of a vapor or aerosol or mixture thereof, wherein such terms are also interchangeably used herein except where otherwise specified.
As noted above, the aerosol delivery device may incorporate a battery or other electrical power source (e.g., a capacitor) to provide current flow sufficient to provide various functionalities to the aerosol delivery device, such as powering of a heater, powering of control systems, powering of indicators, and the like. The power source can take on various embodiments. Preferably, the power source is able to deliver sufficient power to rapidly heat the heating element to provide for aerosol formation and power the aerosol delivery device through use for a desired duration of time. The power source preferably is sized to fit conveniently within the aerosol delivery device so that the aerosol delivery device can be easily handled. Additionally, a preferred power source is of a sufficiently light weight to not detract from a desirable smoking experience.
More specific formats, configurations and arrangements of components within the aerosol delivery device of the present disclosure will be evident in light of the further disclosure provided hereinafter. Additionally, the selection of various aerosol delivery device components can be appreciated upon consideration of the commercially available electronic aerosol delivery devices. Further, the arrangement of the components within the aerosol delivery device can also be appreciated upon consideration of the commercially available electronic aerosol delivery devices.
One example embodiment of an aerosol delivery device 100 is illustrated in
In specific embodiments, one or both of the cartridge 200 and the control body 300 may be referred to as being disposable or as being reusable. For example, the control body 300 may have a replaceable battery or a rechargeable battery and thus may be combined with any type of recharging technology, including connection to a typical alternating current electrical outlet, connection to a car charger (i.e., cigarette lighter receptacle), and connection to a computer, such as through a universal serial bus (USB) cable. Further, in some embodiments the cartridge 200 may comprise a single-use cartridge, as disclosed in U.S. Pat. App. Pub. No. 2014/0060555 to Change et al., which is incorporated herein by reference in its entirety.
With respect to the flow sensor 310, representative current regulating components and other current controlling components including various microcontrollers, sensors, and switches for aerosol delivery devices are described in U.S. Pat. No. 4,735,217 to Gerth et al., U.S. Pat. Nos. 4,922,901, 4,947,874, and 4,947,875, all to Brooks et al., U.S. Pat. No. 5,372,148 to McCafferty et al., U.S. Pat. No. 6,040,560 to Fleischhauer et al., U.S. Pat. No. 7,040,314 to Nguyen et al., and U.S. Pat. No. 8,205,622 to Pan, all of which are incorporated herein by reference in their entireties. Reference also is made to the control schemes described in U.S. App. Pub. No. 2014/0270727 to Ampolini et al., which is incorporated herein by reference in its entirety.
In one embodiment the indicator 318 may comprise one or more light emitting diodes. The indicator 318 can be in communication with the control component 312 through the connector circuit 320 and be illuminated, for example, during a user drawing on a cartridge coupled to the coupler 302, as detected by the flow sensor 310. The end cap 322 may be adapted to make visible the illumination provided thereunder by the indicator 318. Accordingly, the indicator 318 may be illuminated during use of the aerosol delivery device 100 to simulate the lit end of a smoking article. However, in other embodiments the indicator 318 can be provided in varying numbers and can take on different shapes and can even be an opening in the outer body (such as for release of sound when such indicators are present).

Returning to
The base shipping plug 202 may be configured to engage and protect the base 204 prior to use of the cartridge 200. Similarly, the mouthpiece shipping plug 222 may be configured to engage and protect the mouthpiece 220 prior to use of the cartridge 200. The control component terminal 206, the electronic control component 208, the flow director 210, the atomizer 212, and the reservoir substrate 214 may be substantially entirely retained within the outer body 216. The label 218 may at least partially surround the outer body 216 and include information such as a product identifier thereon.
The atomizer 212 may comprise a negative heating terminal 234 and a positive heating terminal 235, a liquid transport element 238 and a heating element 240. In this regard, the reservoir substrate 214 may be configured to hold an aerosol precursor composition. Representative types of aerosol precursor components and formulations are also set forth and characterized in U.S. Pat. No. 7,726,320 to Robinson et al. and U.S. Pat. Pub. Nos. 2013/0008457 to Zheng et al.; 2013/0213417 to Chong et al. and 2014/0060554 to Collett et al., 2015/0020823 to Lipowicz et al.; and 2015/0020830 to Koller, as well as WO 2014/182736 to Bowen et al, the disclosures of which are incorporated herein by reference. Other aerosol precursors that may be employed include the aerosol precursors that have been incorporated in the VUSE® product by R. J. Reynolds Vapor Company, the BLU product by Lorillard Technologies, the MISTIC MENTHOL product by Mistic Ecigs, and the VYPE product by CN Creative Ltd. Also desirable are the so-called “smoke juices” for electronic cigarettes that have been available from Johnson Creek Enterprises LLC. Embodiments of effervescent materials can be used with the aerosol precursor, and are described, by way of example, in U.S. Pat. App. Pub. No. 2012/0055494 to Hunt et al., which is incorporated herein by reference. Further, the use of effervescent materials is described, for example, in U.S. Pat. No. 4,639,368 to Niazi et al.; U.S. Pat. No. 5,178,878 to Wehling et al.; U.S. Pat. No. 5,223,264 to Wehling et al.; U.S. Pat. No. 6,974,590 to Pather et al.; and U.S. Pat. No. 7,381,667 to Bergquist et al., as well as US Pat. Pub. Nos. 2006/0191548 to Strickland et al.; 2009/0025741 to Crawford et al; 2010/0018539 to Brinkley et al.; and 2010/0170522 to Sun et al.; and PCT WO 97/06786 to Johnson et al., all of which are incorporated by reference herein.
The reservoir substrate 214 may comprise a plurality of layers of nonwoven fibers formed into the shape of a tube encircling the interior of the outer body 216 of the cartridge 200. Thus, liquid components, for example, can be sorptively retained by the reservoir substrate 214. The reservoir substrate 214 is in fluid connection with the liquid transport element 238. Thus, the liquid transport element 238 may be configured to transport liquid from the reservoir substrate 214 to the heating element 240 via capillary action or other liquid transport mechanisms.
As illustrated, the liquid transport element 238 may be in direct contact with the heating element 240. As further illustrated in
However, various other embodiments of methods may be employed to form the heating element 240, and various other embodiments of heating elements may be employed in the atomizer 212. For example, a stamped heating element may be employed in the atomizer, as described in U.S. Pat. App. Pub. No. 2014/0270729 to DePiano et al., which is incorporated herein by reference in its entirety. Further to the above, additional representative heating elements and materials for use therein are described in U.S. Pat. No. 5,060,671 to Counts et al.; U.S. Pat. No. 5,093,894 to Deevi et al.; U.S. Pat. No. 5,224,498 to Deevi et al.; U.S. Pat. No. 5,228,460 to Sprinkel Jr., et al.; U.S. Pat. No. 5,322,075 to Deevi et al.; U.S. Pat. No. 5,353,813 to Deevi et al.; U.S. Pat. No. 5,468,936 to Deevi et al.; U.S. Pat. No. 5,498,850 to Das; U.S. Pat. No. 5,659,656 to Das; U.S. Pat. No. 5,498,855 to Deevi et al.; U.S. Pat. No. 5,530,225 to Hajaligol; U.S. Pat. No. 5,665,262 to Hajaligol; U.S. Pat. No. 5,573,692 to Das et al.; and U.S. Pat. No. 5,591,368 to Fleischhauer et al., the disclosures of which are incorporated herein by reference in their entireties. Further, chemical heating may be employed in other embodiments. Various additional examples of heaters and materials employed to form heaters are described in U.S. Pat. No. 8,881,737 to Collett et al., which is incorporated herein by reference, as noted above.
A variety of heater components may be used in the present aerosol delivery device. In various embodiments, one or more microheaters or like solid state heaters may be used. Embodiments of microheaters that may be utilized are further described herein. Further microheaters and atomizers incorporating microheaters suitable for use in the presently disclosed devices are described in U.S. Pat. No. 8,881,737 to Collett et al., which is incorporated herein by reference in its entirety.
The negative heating terminal 234 and the positive heating terminal 235 (e.g., positive and negative terminals) at the opposing ends of the heating element 240 are configured to form an electrical connection with the control body 300 when the cartridge 200 is connected thereto. Further, when the control body 300 is coupled to the cartridge 200, the electronic control component 208 may form an electrical connection with the control body through the control component terminal 206. The control body 300 may thus employ the electronic control component 208 to determine whether the cartridge 200 is genuine and/or perform other functions. Further, various examples of electronic control components and functions performed thereby are described in U.S. Pat. App. Pub. No. 2014/009678 to Sears et al., which is incorporated herein by reference in its entirety.
During use, a user may draw on the mouthpiece 220 of the cartridge 200 of the aerosol delivery device 100. This may pull air through an opening in the control body 300 or in the cartridge. For example, in one embodiment an opening may be defined between the coupler 302 and the outer body 304 of the control body 300, as described in U.S. Pat. App. Pub. No. 2014/0261408 to DePiano et al.; which is incorporated herein by reference in its entirety. However, the flow of air may be received through other parts of the aerosol delivery device 100 in other embodiments. As noted above, in some embodiments the cartridge 200 may include the flow director 210. The flow director 210 may be configured to direct the flow of air received from the control body 300 to the heating element 240 of the atomizer 212.
A sensor in the aerosol delivery device 100 (e.g., a puff or flow sensor in the control body 300) may sense the puff. When the puff is sensed, the control body 300 may direct current to the heating element 240 through a circuit including the negative heating terminal 234 and the positive heating terminal 235. Accordingly, the heating element 240 may vaporize the aerosol precursor composition directed to an aerosolization zone from the reservoir substrate 214 by the liquid transport element 238. Thus, the mouthpiece 220 may allow passage of air and entrained vapor (i.e., the components of the aerosol precursor composition in an inhalable form) from the cartridge 200 to a consumer drawing thereon.
Various other details with respect to the components that may be included in the cartridge 200, are provided, for example, in U.S. Pat. App. Pub. No. 2014/0261495 to DePiano et al., which is incorporated herein by reference in its entirety. In this regard,
Various components of an aerosol delivery device according to the present disclosure can be chosen from components described in the art and commercially available. Reference is made for example to the reservoir and heater system for controllable delivery of multiple aerosolizable materials in an electronic smoking article disclosed in U.S. Pat. App. Pub. No. 2014/0000638 to Sebastian et al., which is incorporated herein by reference in its entirety.
Note further that portions of the cartridge 200 illustrated in
In another embodiment substantially the entirety of the cartridge may be formed from one or more carbon materials, which may provide advantages in terms of biodegradability and absence of wires. In this regard, the heating element may comprise carbon foam, the reservoir may comprise carbonized fabric, and graphite may be employed to form an electrical connection with the battery and controller. An example embodiment of a carbon-based cartridge is provided in U.S. Pat. App. Pub. No. 2013/0255702 to Griffith et al., which is incorporated herein by reference in its entirety.
As described above, cartridges of aerosol delivery devices may include a number of components. Some of the components may be relatively small and/or relatively delicate. Accordingly, precise manufacturing techniques may be required to form the aerosol delivery devices. In this regard, aerosol delivery devices have traditionally been formed via manual assembly. However, use of manual labor to assemble aerosol delivery devices suffers from certain detriments. In this regard, the quality of aerosol delivery devices produced via manual labor is only as good as the workers performing the labor. Further, even skilled workers may make errors from time-to-time. Additionally, manual labor may be relatively costly. Accordingly, as result of these issues and other issues associated with the production of aerosol delivery devices via manual labor, it may be desirable to produce aerosol delivery devices in an automated manner. Accordingly, automated production of cartridges for aerosol delivery devices is discussed hereinafter, which may provide enhanced repeatability, lower costs, and/or avoid other issues noted above.
In this regard,
As illustrated, the system 400 may include various subsystems that perform particular functions in the formation of the completed cartridges 200. Note that although the subsystems are illustrated as being separate from one another, the subsystems may overlap. For example, in some embodiments common equipment may perform two or more functions (e.g., assembly and filling or capping and labeling, etc.), rather than the particular functions being performed by separate equipment.
Further, the various subsystems and portions thereof may be separately usable. In this regard, although the subsystems and portions thereof are generally described herein as being usable together, this is by way of example. Accordingly, any of the subsystems or portions thereof described herein may be usable by themselves or in any combination with some or all of the other subsystems and portions thereof described herein. Further, although particular embodiments of portions of the subsystems are disclosed hereinafter, these embodiments are provided for example purposes only. Accordingly, in some embodiments the subsystems may include fewer or additional portions. Thus, each portion of each subsystem, and each portion of the overall system is not required in all embodiments.
As illustrated, the subsystems may include a cartridge assembly subsystem 402 configured to form unfilled cartridges 404 from components 406 (e.g., the base 204, the heating terminals 234, 235, etc.). A cartridge filling subsystem 408 may fill the unfilled cartridges 404 to produce filled cartridges 410. A cartridge capping subsystem 412 may cap the filled cartridges 410 to produce capped cartridges 414. A cartridge labeling subsystem 416 may apply labels to the capped cartridges 414 to complete the completed cartridges 200.
The system 400 may additionally include an inspection subsystem 418. The inspection subsystem 418 may inspect the components 406, the unfilled cartridges 404, the filled cartridges 410, the capped cartridges 414, and/or the completed cartridges 200. Further, in some embodiments the cartridges may be inspected at intermediate states of completion at one or more of the cartridge assembly subsystem 402, the cartridge filling subsystem 408, the cartridge capping subsystem 412, and the cartridge labeling subsystem 416. Accordingly, the cartridges 200 and components thereof may be inspected before, during, and after completion thereof.
The system may further at least one controller 417. The controller 417 may be configured to control the cartridge assembly subsystem 402, the cartridge filling subsystem 408, the cartridge capping subsystem 412, and/or the cartridge labeling subsystem 416. In this regard, the controller may be configured to receive data from one or more of the sensors described herein and output instructions based thereon, in addition to otherwise directing the operations described herein.
Note that some or all of the system 400 may be automated. In this regard, as described hereinafter, robotic apparatuses may be employed in some embodiments of the system 400. The robotic apparatuses may be provided from various robotic manufacturers including, by way of example, DENSO Robotics of Long Beach, Calif., FANUC of Rochester Hills, Mich., Mitsubishi Electric Automation of Vernon Hills, Ill., EPSON Robots of Carson, Calif., and Siemens Automation Technology of Munich, Germany.
An example embodiment of the cartridge assembly subsystem 402 is schematically illustrated in
As illustrated in
Briefly, the base load substation 502 may be configured to receive a base (e.g., the base 204) and orient the base for assembly with the various other components of the cartridge. The control component terminal coupling substation 504, the negative heating terminal coupling substation 506, and the positive heating terminal coupling substation 508 may be respectively configured to couple a control component terminal (e.g., the control component terminal 206) a negative heating terminal (e.g., the negative heating terminal 234) and a positive heating terminal (e.g., the positive heating terminal 235) to the base 204. The control component coupling substation 510 may be configured to couple a control component (e.g., the electronic control component 208) to the control component terminal 206. The flow director coupling substation 512 may be configured to couple a flow director (e.g., the flow director 210) to the control component 208, the negative and positive heating terminals 234, 235, and/or other components. The heating element coupling substation 514 may be configured to couple a heating element (e.g., the heating element 240) to the negative and positive heating terminals 234, 235. The reservoir and outer body coupling substation 516 may be configured to bend the liquid transport element (e.g., the liquid transport element 238), to wrap a reservoir (e.g., the reservoir 214) around the atomizer (e.g., the atomizer 212) and to engage an outer body (e.g., the outer body 216) to the base 204. The outer body crimping and inspection substation 518 may be configured to crimp the outer body 216 to the base 204 and inspect the cartridges 200.
The cartridge assembly subsystem 402 may assemble the cartridge (e.g., the cartridge 200) in a variety of manners. For example, in one embodiment the cartridge 200 may be assembled generally upwardly from the base 204. In other words, components may be inserted into or otherwise coupled to the base 204, or coupled to components previously coupled to the base, to build up the cartridge 200 therefrom.
In this regard, as further illustrated in
The carriages 604 may be configured to engage the base 204 such that a remainder of the components of the cartridge 200 may be coupled thereto. In this regard, as discussed below, the base 204 may be engaged with the carriage 604 at the base load substation 502. Thereafter additional components may be generally directed downwardly into contact with the base 204, or components previously coupled to the base, such that the cartridge 200 is built generally upwardly from the base as various components are coupled thereto at the remaining substations 504-518.
Accordingly, the carriages 604 may be configured to grasp the base 204. In this regard, each carriage 604 may include at least one engagement head configured to engage the base 204. In some embodiments each carriage 604 may include a plurality of engagement heads, such that multiple cartridges may be assembled thereon in order to improve assembly speed and efficiency. For example, as illustrated in
The engagement heads 608a, 608b may be configured to engage a respective base 204 in a firm manner that does not interfere with attachment of the other components to the base. In this regard, in some embodiments the engagement heads 608a, 608b may be configured to engage an internal surface 242 of an attachment end 244 of each base 204 (see,
In particular, as illustrated in
As illustrated in
As further illustrated in
As further illustrated in
Accordingly, the track 602 may be configured to transport the carriages 604 therealong to the various assembly substations 502-518. In this regard, the empty cartridges 604 may first be directed to the base load substation 502. The base load substation 502 may be configured to rotationally align a base 204 with each engagement head 608a, 608b of the carriage 604 and engage the bases with the engagement heads.
In this regard,
In this regard,
The bases 204 may be loaded into the vibratory hopper 708. As the vibratory hopper 708 vibrates, the bases 204 gradually travel under a gate 714 and fall into the vibratory bowl 710 so as to provide the vibratory bowl with a substantially constant supply of the bases. In this regard, a component level sensor 716 may detect a level of the bases 204 within the vibratory bowl 710. Thereby, the vibratory hopper 708 may start and stop based on the level of the bases 204 within the vibratory bowl 710 as detected by the component level sensor 716. The vibratory hopper 708 may thus maintain a substantially constant level of the bases 204 within the vibratory bowl 710 as the bases are transported therefrom.
The vibratory bowl 710 may define a pathway 718 configured to arrange the bases 204 in a serially-aligned stream 720. In this regard, the vibratory motion of the vibratory bowl 710 may direct the bases 204 upwardly along the pathway 718, which may narrow such that some bases fall therefrom and the bases that remain on the pathway become serially-aligned. The vibratory bowl 710 may be configured to arrange the bases 204 such that the attachment end 244 is oriented downwardly and the inner end 246 is oriented upwardly (see,
However, some bases 204 in the serially-aligned stream 720 may be oriented upside down or otherwise oriented in a manner that differs from the desired orientation. In this regard, the supply unit 702 may further comprise an actuator 724 configured to individually remove or realign the bases 204 in the serially-aligned stream 720 when the bases are misaligned in a direction. In one embodiment the actuator 724 may comprise a nozzle 726 configured to direct a flow of air at each base 204 that is misaligned to remove the base from the pathway 718 or push the base into proper alignment. In some embodiments the nozzle 726 may be oriented so as to only impact those bases 204 that are misaligned with the flow of air (i.e., if a base is misaligned, it will be impacted by the flow of air from the nozzle and removed or re-aligned). In another embodiment the supply unit 702 may further comprise an orientation sensor 722 (e.g., a camera) configured to determine an alignment of the bases 204 on the pathway 718, and the actuator 724 may be actuated in response thereto when a misaligned base is detected.
Accordingly, each of the bases 204 in the serially-aligned stream 720 may be properly oriented downstream of the actuator 724. The bases 204 removed by the actuator 724 may be directed back into the vibratory bowl 710 such that the bases 204 may be returned to the pathway 718. In some embodiments the pathway may define a gap or other feature configured to remove the components from the serially-aligned stream when the components are misaligned in a second direction. For example, such a gap or other feature may be configured to allow the bases resting on their outer circumference to roll off of the pathway.
Accordingly, the serially-aligned stream 720 of the bases 204 may be directed to the supply track 712, which may maintain the bases in the upwardly-extending orientation and in the single-file arrangement. In some embodiments the supply track 712 may comprise a vibratory supply track to facilitate movement of the bases 204 therealong. As illustrated, the supply track 712 may include a full sensor 726 configured to detect whether the supply track is full of the bases 204. In this regard, when the full sensor 726 senses that the supply track 712 is full, the vibratory bowl 710 may be shut off. Further, the supply track 712 may include a low level sensor 728 configured to detect when the supply track is running low on the bases 204. In this regard, when the low level sensor 728 detects a low level of the bases 204 in the supply track 712, an indicator 730 (see,
Further, as illustrated in
After the first base 204a is received in the first engagement head 740a, the rotary member 738 may swivel (e.g., by rotating counterclockwise when viewed from above) to a first delivery position, which corresponds to the second receiving position, and which is illustrated in
The first end effector 748a may be configured to engage the first base 204a and deliver the first base to a carriage 604 engaged with the track 602 via movement of the first robotic arm 748a. Thus, the first assembly unit 706a may be positioned such that the first robotic arm 746a is configured to move the first end effector 748a between the feeder unit 704 and the track 602. In this regard, when the rotary member 738 is in the first delivery position (see,
As illustrated in
For example,
Accordingly, the carriage 604 may be positioned for receipt of the first base 204a following rotational alignment thereof. In this regard,
Accordingly, the carriage 604 may be directed into the base load substation 502 along the track 602. The carriage 604 may thereby enter the first processing portion 754a. As illustrated in
As illustrated in
Accordingly, the track 602 may move the carriage 604 until the carriage engages a lift stop 764a. In particular the stop bar 628 on the carriage (see,
The lifter mechanism 770a may comprise a first locking pin 772a and a second locking pin 774a configured to engage the carriage 604. In particular, the first locking pin 772a may be configured to engage the first alignment aperture 618a defined by the first collet 610a (see,
After the robotic arm 748a completes the base engagement operation, a storage transceiver 776a may write code to the storage module 624 indicating whether or not the first base 204a was properly coupled to the first engagement head 608a. In this regard, a component presence sensor 778a (e.g., comprising a light emitter and receiver; see
Thereafter, the lifter mechanism 770a may release the carriage 604 by lowering the carriage back onto the conveyor belts 628. At such time the carriage 604 may be directed to the second processing portion 754b. The second processing portion 754b may comprise the same components included in the first processing portion 754a. For example, as illustrated in
In this regard, as illustrated in
While the first engagement head 740a receives one of the bases 204, the second engagement head 740b may feed the second base 204b received therein to the second assembly unit 706b. Accordingly, the rotary member 738 may swivel back and forth such that the bases are individually delivered by the feeder unit 704 to the first assembly unit 706a and the second assembly unit 706b. Thus, the first receiving position may correspond to the second delivery position and the second receiving position may correspond to the first delivery position.
Thereby, the second assembly unit 706b may engage the second base 204b with the second engagement head 608b in the manner described above with respect to the first assembly unit 706a. In this regard, briefly, the second robotic arm 746b may engage the second base 204b via the second end effector 748b, lift and rotate the second base to the proper orientation based on an image provided by the second rotational alignment imaging device 750b, and engage the second base with the second engagement head 608b in the proper orientation while the lifter mechanism 770b engages the carriage 604. At such time, the second end effector 746b may stop applying negative pressure, such that the second base 204b may release therefrom and remain in engagement with the second engagement head 608b. The second robotic arm 746b may return to an initial position proximate the rotary member 738.
After the second robotic arm 746b completes the base engagement operation, a second storage transceiver 776b may write code to the storage module 624 indicating whether or not the second base 204b was properly coupled to the second engagement head 608b. In this regard, a component presence sensor 778b (e.g., comprising a light emitter and receiver; see
The lifter mechanism 770b may lower such that the track 602 transports the carriage 604 including the first and second bases 204a, 204b coupled thereto downstream. The carriage 604 may be directed out of the base load substation 502 by the track 602. As illustrated in
In this regard,
The control component terminals 206 may be loaded into the vibratory hopper 808. As the vibratory hopper 808 vibrates, the control component terminals 206 gradually travel under a gate 814 and fall into the vibratory bowl 810 so as to provide the vibratory bowl with a substantially constant supply of the control component terminals. In this regard, a component level sensor 816 may detect a level of the control component terminals 206 within the vibratory bowl 810. Thereby, the vibratory hopper 808 may start and stop based on the level of the control component terminals 206 within the vibratory bowl 810 as detected by the component level sensor 816. Accordingly, the vibratory hopper 808 may maintain a substantially constant level of the control component terminals 206 within the vibratory bowl 810 as the control component terminals are transported therefrom.
The vibratory bowl 810 may define a pathway 818 configured to arrange the control component terminals 206 in a serially-aligned stream 820 (see,
As illustrated in
Accordingly, each of the control component terminals 206 in the serially-aligned stream 820 may be properly oriented downstream of the actuator 824. The control component terminals 206 removed by the actuator 824 may be directed back into the vibratory bowl 810 such that the control component terminals may be returned to the pathway 818. In some embodiments the pathway may define a gap or other feature configured to remove the components from the serially-aligned stream when the components are misaligned in a second direction. For example, longitudinally oriented control component terminals 206 may fall through the gap 818a in the pathway 818 (see,
Accordingly, the serially-aligned stream 820 of the control component terminals 206 may be directed to the supply track 812, which may maintain the control component terminals in the horizontal orientation and in the single-file arrangement. In some embodiments the supply track 812 may comprise a vibratory supply track 812 to facilitate movement of the control component terminals 206 therealong. As illustrated in
Further, as illustrated in
In this regard,
The first end effector 848a may be configured to engage the control component terminal 206. As illustrated in
Further, the first end effector 848a may be configured to rotate between a horizontal configuration employed to grasp and remove the control component terminal 206 from the singulator 832 and a vertical configuration (see,
In this regard, a carriage 604 with the first and second bases 204a, 204b engaged therewith may be directed through the control component terminal coupling substation 504. As illustrated in
Accordingly, a carriage 604 may be transported to the first processing portion 854a along the track 602. The carriage 604 may be directed past a carriage sensor 856a, which may comprise a light emitter and detector, and which detects the presence of the carriage 604. After passing the carriage sensor 856a, the carriage 604 may be directed past an initial locator sensor 858a configured to detect the locator module 626 and verify the presence and location of the carriage. An initial stop 860a may then stop the carriage 604 in the manner described above with respect to the initial stop 760a of the base load substation 502 (see,
The track 602 may include a lifter mechanism 870a (see,
After the robotic arm 846a completes the base engagement operation, a storage transceiver 876a may write code to the storage module 624 indicating whether or not the first control component terminal 206a was properly coupled to the first base 204a. In this regard, a component presence sensor 878a (e.g., comprising a light emitter and receiver) may detect whether the first control component terminal 206a is engaged with the first base 204a following movement of the first robotic arm 846a as described above. For example, the component presence sensor 878a may detect whether or not the first control component terminal 206a is present while the carriage 604 is lifted by the lifter mechanism 870a. In instances in which the first control component terminal 206a is not properly engaged with the first base 204a, the substations downstream of the base load substation 502 may not perform additional operations that would be otherwise conducted on the first base 204a. In other words, in light of the first control component terminal 206a being improperly attached to the base 204a or missing, the substations downstream of the control component terminal coupling substation 504 may not attempt to couple additional components thereto, so as to avoid damage to the remaining substations and waste of components. In this same regard, the storage transceiver 876a may read the code on the storage module 624 to determine that the partially-assembled cartridge is fit for further assembly prior to coupling the control component terminal 206a to the base 204a. Thus, the various storage transceivers disclosed herein may read the storage module before a particular operation is performed to determine whether to perform the operation, and write to the storage module after the operation to reflect whether or not the operation was properly completed.
Thereafter, the lifter mechanism 870a may release the carriage 604 by lowering the carriage back onto the conveyor belts 628 of the track 602. At such time the carriage 604 may be directed to the second processing portion 854b by the track 602. The second processing portion 854b may comprise the same components included in the first processing portion 854a.
For example, as illustrated in
After the second robotic arm 846b completes the control component terminal engagement operation, a second storage transceiver 876b may write code to the storage module 624 indicating whether or not the second control component terminal 206b was properly engaged with the second base 204b. In this regard, a component presence sensor 878b (e.g., comprising a light emitter and receiver) may detect whether the second control component terminal 206b is properly engaged with the second base 204b following movement of the second robotic arm 846b as described above. For example, the component presence sensor 878b may detect whether or not the second control component terminal is present while the carriage 604 is lifted by the lifter mechanism 870b. In instances in which the second control component terminal 206b is not properly engaged with the second base 204b additional operations that would be otherwise conducted on the second base downstream of the second robotic arm 846b may not be conducted so as to avoid damage to the remaining substations and waste of components. In this same regard, the storage transceiver 876b may read the code on the storage module 624 to determine that the partially-assembled cartridge is fit for further assembly prior to coupling the control component terminal 206b to the base 204b.
The lifter mechanism 870b may then lower such that the track 602 transports the carriage 604 including the control component terminals 206a, 206b respectively coupled to bases 204a, 204b downstream. However, as illustrated in
The control component terminal coupling substation 504 may further comprise a press 880. The press 880 may be configured to press the control component terminals 206a, 206b into full engagement with the bases 204a, 204b while the carriage 604 is lifted by the lifter mechanism 870c. In this regard, as a result of the control component terminals 206a, 206b being relatively short, the first and second assembly units 806a, 806b may not be able to fully insert the control component terminals using the robotic arms 846a, 846b and end effectors 848a, 848b, and hence the press 880 may be employed to fully engage the control component terminals. However, in other embodiments the press may not be employed. Following operation of the press 880, a storage transceiver 876c may write code to the storage module 624 indicating whether or not the control component terminals 206a, 206b were properly pressed into the bases 204a, 204a (e.g., based on completion of a full downward stroke of the press 880).
Note that the above-described operations may be conducted simultaneously. In this regard, while the first robotic arm 846a couples the first control component terminal 206a to the first base 204a, the second robotic arm 846b may receive the second control component terminal 206b from the singulator 832. Conversely, while the second robotic arm 846b couples the second control component terminal 206b to the second base 204b, the first robotic arm 846a may receive the first control component terminal 206a from the singulator 832. Further, the press 880 may press the control component terminals 206a, 206b into full engagement with the bases 204a, 204b while other operations are ongoing, such as while the first robotic arm 846a couples the first control component terminal 206a to the first base 204a and the second robotic arm 846b receives the second control component terminal 206b from the singulator 832. Accordingly, rapid and efficient engagement of the control component terminals 206a, 206b with the bases 204a, 204b may be achieved.
The negative heating terminal coupling substation 506 and the positive heating terminal coupling substation 508 may be positioned downstream from the control component terminal coupling substation 504. For example, in one embodiment the negative heating terminal coupling substation 506 may be positioned downstream from the control component coupling substation 506 and the positive heating terminal coupling substation 508 may be positioned downstream of the negative heating terminal coupling substation. The negative heating terminal coupling substation 506 and the positive heating terminal coupling substation 508 may be substantially similar. In this regard, although the description provided below is directed to the negative heating terminal coupling substation 506, such description is applicable to both the negative heating terminal coupling substation and the positive heating terminal coupling substation 508, except as otherwise noted.
In this regard,
The negative heating terminals 234 may be loaded into the vibratory hopper 908. As the vibratory hopper 908 vibrates, the negative heating terminals 234 gradually travel under a gate 914 and fall into the vibratory bowl 910 so as to provide the vibratory bowl with a substantially constant supply of the negative heating terminals. In this regard, a component level sensor 916 may detect a level of the negative heating terminals 234 within the vibratory bowl 910. Thereby, the vibratory hopper 908 may start and stop based on the level of the negative heating terminals 234 within the vibratory bowl 910 as detected by the component level sensor 916. Accordingly, the vibratory hopper 908 may maintain a substantially constant level of the negative heating terminals 234 within the vibratory bowl 910 as the negative heating terminals are transported therefrom.
The vibratory bowl 910 may define a pathway 918 configured to arrange the negative heating terminals 234 in a serially-aligned stream 920 (see,
As illustrated in
Accordingly, each of the negative heating terminals 234 in the serially-aligned stream 920 may be properly oriented downstream of the actuator 924. The negative heating terminals 234 removed by the actuator 924 may be directed back into the vibratory bowl 910 such that the negative heating terminals may be returned to the pathway 918. In some embodiments the pathway may define a gap or other feature configured to remove the components from the serially-aligned stream when the components are misaligned in a second direction.
Accordingly, the serially-aligned stream 920 of the negative heating terminals 234 may be directed to the supply track 912, which may maintain the negative heating terminals in the vertical orientation and in the single-file arrangement. In some embodiments the supply track 912 may comprise a vibratory supply track to facilitate movement of the negative heating terminals 234 therealong. As illustrated in
Further, as illustrated in
As illustrated, when the outermost negative heating terminal 234 is singulated between the first stop 934 and the second stop 938, a biasing member 940 may engage the outermost negative heating terminal 234 such that the outermost negative heating terminal 234 is further separated from the remaining negative heating terminals. In particular, the biasing member 940 may be configured to extend upwardly to engage the downwardly-extending upper end 258 of the outermost negative heating terminal 234. In this regard, the biasing member 940 may define an angled surface 942 that engages and presses outwardly on the upper end 258 of the outermost negative heating terminal 234 as the biasing member 940 extends upward.
After the outermost negative heating terminal 234 is singulated, this negative heating terminal may be transferred to the feeder unit 904.
The rotary member 944 may be configured to swivel between a first receiving position at which the first engagement head 946a is positioned proximate the feeder 902 and a second receiving position (see,
A first gripper extender 954a may then extend the first gripper 948a, which is open, around the first negative heating terminal 234a. The first gripper 948a may then shut so as to clamp onto the first heating terminal 234a. A second horizontal actuator 956 (see,
A terminal load sensor 958 (e.g., an optical sensor) may detect whether the first gripper 948a properly gripped the first heating terminal 234a. The rotary member 944 may then swivel to a first delivery position (e.g., by rotating clockwise when viewed from above) to a first delivery position, which corresponds to the second receiving position, and which is illustrated in
The first end effector 962a may be configured to engage the first negative heating terminal 234a and deliver the first negative heating terminal to the first base 204a on a carriage 604 on the track 602 via movement of the first robotic arm 960a. Thus, the first assembly unit 906a may be positioned such that the first robotic arm 960a is configured to move the first end effector 962a between the feeder unit 904 and the track 602. In this regard, when the rotary member 944 is in the first delivery position (see,
Accordingly, the first end effector 962 may be configured to engage the first negative heating terminal 234a. As illustrated in
As described above, the singulator 932 may supply the first negative heating terminals 234a upside down, with the upper end 258 thereof pointing downwardly, and this orientation may be maintained by the supply unit 904, such that the first end effector 962a receives the first negative heating terminals in this inverted orientation. In particular, the first end effector 962a may grasp each first negative heating terminal 234a between the upper end 258 and the lower end 260, substantially at a middle thereof. The first end effector 962a may thereby rotate one hundred eighty degrees such that the lower end 260 of the first negative heating terminal 234a is pointed downwardly, as illustrated in
Accordingly, the track 602 may move the carriage 604 such that the first base 204a is positioned for receipt of the first negative heating terminal 234a. In this regard, a carriage 604 with the first and second bases 204a, 204b engaged therewith, and the control component terminals 206a, 206b engaged with the bases may be directed through the negative heating terminal coupling substation 506. As illustrated in
Accordingly, a carriage 604 may be transported along the track 602 to the first processing portion 968a. The carriage 604 may be directed past a carriage sensor 970a, which may comprise a light emitter and detector, and which detects presence of the carriage 604. After passing the carriage sensor 970a, the carriage 604 may be directed past an initial locator sensor 972a configured to detect the locator module 626 and verify the presence and location of the carriage. An initial stop 974a may then stop the carriage 604 in the manner described above with respect to the initial stop 760a of the base load substation 502 (see,
The track 602 may include a lifter mechanism 980a configured to lift the carriage 604 after the presence and location thereof is verified by the stop locator sensor 978a in the manner described above with respect to the lifter mechanism 770a of the base load substation 502 (see,
In some embodiments the first assembly unit 906a may include a first pusher 982a positioned proximate the first end effector 962a. As illustrated in
After the robotic arm 960a engages the first negative heating terminal 234a with the first base 204a, a storage transceiver (not shown; see, e.g., storage transceiver 984b) may write code to the storage module 624 indicating whether or not the first negative heating terminal 234a was properly coupled to the first base 204a. In this regard, a component presence sensor 986a (e.g., comprising a light emitter and receiver) may detect whether the first negative heating terminal 234a is engaged with the first base 204a following movement of the first robotic arm 960a as described above. For example, the component presence sensor 986a may detect whether or not the first negative heating terminal 234a is present while the carriage 604 is lifted by the lifter mechanism 980a. In instances in which the first negative heating terminal 234a is not properly engaged with the first base 204a, the substations downstream of the base load substation 502 may not perform additional operations that would be otherwise conducted on the first base 204a. In other words, in light of the first negative heating terminal 234a being improperly attached to the base 204a or missing, the substations downstream of the negative heating terminal coupling substation 506 may not attempt to couple additional components thereto, so as to avoid damage to the remaining substations and waste of components. In this same regard, the storage transceiver may read the code on the storage module 624 to determine that the partially-assembled cartridge is fit for further assembly prior to coupling the negative heating terminal 234a to the base 204a.
Thereafter, the lifter mechanism 980a may release the carriage 604 by lowering the carriage back onto the conveyor belts 628. At such time the carriage 604 may be directed along the track 602 to the second processing portion 968b. The second processing portion 968b may comprise the same components included in the first processing portion 968a. For example, as illustrated in
In this regard, while the first negative heating terminal 234a is delivered to the first assembly unit 906a for insertion in the first base 204a, the second negative heating terminal 234b may be singulated from the serially-aligned stream 920 of negative heating terminals. In particular, with reference to
Accordingly, the second gripper 948b of the feeder unit 904 may engage the second negative heating terminal 234b. Thereby, the feeder unit 904 may swivel (e.g., by rotating counterclockwise when viewed from above), and position the second negative heating terminal 234b proximate the track 602. The second robotic arm 960b, the second end effector 962b, and a second pusher (not shown; see, e.g., pusher 982a) may then engage the second negative heating terminal 234b in the negative heating terminal aperture 248b of the second base 204b in the manner described above.
After the second robotic arm 960b completes the second negative heating terminal engagement operation, the second storage transceiver 984b may write code to the storage module 624 indicating whether or not the second negative heating terminal 234b was properly engaged with the second base 204b. In this regard, a component presence sensor 986b (e.g., comprising a light emitter and receiver) may detect whether the second negative heating terminal 234b is properly engaged with the second base 204b following movement of the second robotic arm 960b as described above. For example, the component presence sensor 986b may detect whether or not the second negative heating terminal 234b is present while the carriage 604 is lifted by the lifter mechanism 980b. In instances in which the second negative heating terminals 234b is not properly engaged with the second base 204b additional operations that would be otherwise conducted on the second base downstream of the second robotic arm 960b may not be conducted so as to avoid damage to the remaining substations and waste of components. Following attachment of the second negative heating terminal 234b and detection of presence or absence thereof, the lifter mechanism 980b may lower the carriage 604 such that the track 602 transports the carriage including the negative heating terminals 234a, 234b respectively coupled to bases 204a, 204b downstream. In this same regard, the storage transceiver 984b may read the code on the storage module 624 to determine that the partially-assembled cartridge is fit for further assembly prior to coupling the negative heating terminal 234b to the base 204b.
Note that the above-described operations may be conducted simultaneously. In this regard, while the first engagement head 946a delivers the first negative heating terminal 234a to the first robotic arm 960a, the second engagement head 946b may receive the second negative heating terminal 234b from the singulator 932. Conversely, while the second engagement head 946b delivers the second negative heating terminal 234b to the second robotic arm 960b, the first engagement head 946a may receive the first negative heating terminal 234a from the singulator 932. Further, while the first robotic arm 960a couples the first negative heating terminal 234a to the first base 204a, the second robotic arm 960b may receive the second negative heating terminal 234b from the rotary member 944. Conversely, while the second robotic arm 960b couples the second negative heating terminals 235 to the second base 204b, the first robotic arm 960a may receive the first negative heating terminal 234a from the rotary member 944. Accordingly, rapid and efficient engagement of the negative heating terminals 234a, 234b with the bases 204a, 204b may be achieved.
As noted above, the positive heating terminal coupling substation 508 may be substantially similar to the negative heating terminal coupling substation 506. Accordingly, a description of the various components of the positive heating terminal coupling substation 508 will not be repeated. However, in some embodiments the positive heating terminal coupling substation 508 may additionally include an inspection unit 988, which may be positioned downstream of the first and second assembly units thereof, which may be substantially similar to the first and second assembly units 906a, 906b of the negative heating terminal coupling substation 506, as noted above.
As illustrated in
In some embodiments a backlight 998 may be positioned across from the imaging device 994, such that the terminals 206, 234, 235 are positioned between the imaging device and the backlight, to improve imaging of the terminals. Accordingly, the images captured by the imaging device 994 may be analyzed to determine whether the terminals 206, 234, 235 are missing or improperly engaged with the bases 204. For example, the height to which the terminals 206, 234, 235 extend from the base 204 may be determined and compared to a desired height of the terminals. A third storage transceiver 984c may write code to the storage module 624 indicating whether or not the terminals 206, 234, 235 are properly engaged with the bases 204. In instances in which the terminals 206, 234, 235 are not properly engaged with the bases 204, additional operations that would be otherwise conducted thereon downstream of the positive heating terminal coupling substation 508 may not be conducted so as to avoid damage to the remaining substations and waste of components.
The control component coupling substation 510 may be positioned downstream of the positive heating terminal coupling substation 508.
In this regard,
The electronic control components 208 may be loaded directly into the vibratory bowl 1010, or a vibratory hopper may supply the electronic control components 208 to the vibratory bowl in the manner described above. The vibratory bowl 1010 may define a pathway 1018 configured to arrange the electronic control components 208 in a serially-aligned stream 1020. In this regard, the vibratory motion of the vibratory bowl 1010 may direct the electronic control components 208 upwardly along the pathway 1018, which may narrow such that some electronic control components fall therefrom and the electronic control components that remain on the pathway become serially-aligned.
The vibratory bowl 1010 may be configured to arrange the electronic control components 208 generally horizontally with longitudinal ends thereof contacting one-another. However, some electronic control components 208 in the serially-aligned stream 1020 may be oriented in a manner that differs from the desired orientation. In this regard, as illustrated in
In another embodiment the supply unit 1002 may further comprise an orientation sensor 1028 (e.g., a camera) configured to determine an alignment of the electronic control components 208 on the pathway 1018, and the actuator 1024 may be actuated in response thereto when a misaligned electronic control component is detected. For example as illustrated in
In some embodiments the electronic control components 208 may also be asymmetrical with respect to a first major surface 266 and a second major surface 268. For example, as illustrated in
Alternatively or additionally, as illustrated in
Accordingly, each of the electronic control components 208 in the serially-aligned stream 1020 may be properly oriented downstream of the gap 1030 and the actuator 1024. The electronic control components 208 removed by the gap 1030 and the actuator 1024 may be directed back into the vibratory bowl 1010 such that the electronic control components may be returned to the pathway 1018. Thus, the removed electronic control components 208 may be directed back into the serially-aligned stream 1020.
Thereby the serially-aligned stream 1020 of the electronic control components 208 may be directed to the supply track 1012, which may maintain the electronic control components in the horizontal orientation and in the longitudinal single-file arrangement. In some embodiments the supply track 1012 may comprise a vibratory supply track to facilitate movement of the electronic control components 208 therealong. As illustrated in
Further, as illustrated in
After the first electronic control component 208a is received in the first engagement head 1044a, the rotary member 1042 may swivel (e.g., by rotating clockwise when viewed from above) to a first delivery position, which corresponds to the second receiving position, and which is illustrated in
The first end effector 1054b may be configured to engage the first electronic control component 208a and deliver the first electronic control component to the first base 204a, which is engaged with a carriage 604 on the track 602, via movement of the first robotic arm 1052a. Thus, the first assembly unit 1006a may be positioned such that the first robotic arm 1052a is configured to move the first end effector 1054a between the feeder unit 1004 and the track 602. In this regard, when the rotary member 1042 is in the first delivery position (see,
Accordingly, the first end effector 1054a may be configured to engage the first electronic control component 208a. As illustrated in
Accordingly, the track 602 may move the carriage 604 such that the first base 204a is positioned for receipt of the first electronic control component 208a. In this regard, a carriage 604 with the bases 204 engaged therewith, and the negative heating terminal 234, the positive heating terminal 235, and the control component terminal 206 engaged with the bases, may be directed through the control component coupling substation 510. As illustrated in
Accordingly, a carriage 604 may be transported along the track 502 to the first processing portion 1060a. The carriage 604 may be directed past a carriage sensor 1062a, which may comprise a light emitter and detector, and which detects the presence of the carriage 604. After passing the carriage sensor 1062a, the carriage 604 may be directed past an initial locator sensor 1064a configured to detect the locator module 626 and verify the presence and location of the carriage. An initial stop 1066a may then stop the carriage 604 in the manner described above with respect to the initial stop 760a of the base load substation 502 (see,
The track 602 may include a lifter mechanism 1072a configured to lift the carriage 604 after the presence and location thereof is verified by the stop locator sensor in the manner described above with respect to the lifter mechanism 770a of the base load substation 502 (see,
In this regard, as illustrated in
As illustrated in
After the electronic control component 208 is engaged with the control component terminal 206, the pivoting gripper 1074a may stop applying the negative pressure to the first electronic control component 208a, such that the first electronic control component remains in engagement with the control component terminal 206a between the negative and positive heating terminals 234a, 235a. The first robotic arm 1052a may then return to the feeder unit 1004 to engage an additional first electronic control component for attachment with the first base 204a on a subsequent carriage 604.
After the robotic arm 1060a engages the first electronic control component 208a with the first base 204a (e.g., via the control component terminal 206), a storage transceiver 1078a may write code to the storage module 624 indicating whether or not the first electronic control component 208a was properly coupled to the first base 204a. In this regard, for example, the storage transceiver 1078a may store information to the storage module 624 indicating that the electronic control component 208a is improperly attached unless each of the movements of the components of the first assembly unit 1006a are successfully completed, as detected by various motion sensors associated therewith. In instances in which the first electronic control component 208a is deemed to not be properly engaged with the first base 204a, the substations downstream of the control component coupling substation 510 may not perform additional operations that would be otherwise conducted on the first base 204a. In other words, in light of the first electronic control component 208a being improperly attached to the base 204a or missing, the substations downstream of the electronic control component coupling substation 510 may not attempt to couple additional components thereto, so as to avoid damage to the remaining substations and waste of components. In this same regard, the storage transceiver 1078a may read the code on the storage module 624 to determine that the partially-assembled cartridge is fit for further assembly prior to coupling the electronic control component 208a to the control component terminal 206 coupled to the first base 204a.
Thereafter, the lifter mechanism 1072a may release the carriage 604 by lowering the carriage back onto the conveyor belts 628. At such time the carriage 604 may be directed along the track 602 to the second processing portion 1060b. As illustrated in
In this regard, while the first electronic control component 208a is delivered to the first assembly unit 1006a for engagement with the first base 204a, the second electronic control component 208b may be singulated from the serially-aligned stream 1020 of electronic control components in the manner described above and received in the second pocket 1046b in the second engagement head 1044b, as illustrated in
After the second electronic control component 208b is coupled to the second base 208b, the lifter mechanism 1072b may lower the carriage 604 such that the track 602 transports the carriage downstream. As illustrated, in
Note that the above-described operations may be conducted simultaneously. In this regard, while the first engagement head 1044a delivers the first electronic control component 208a to the first robotic arm 1052a, the second engagement head 1044b may receive the second electronic control component 208b from the singulator 1036. Conversely, while the second engagement head 1044b delivers the second electronic control component 208b to the second robotic arm 1052b, the first engagement head 1044a may receive the first electronic control component 208a from the singulator 1036. Further, while the first robotic arm 1052a couples the first electronic control component 208a to the first base 204a, the second robotic arm 1052b may receive the second electronic control component 208b from the second engagement head 1044a. Conversely, while the second robotic arm 1052b couples the second electronic control components 208b to the second base 204b, the first robotic arm 1052a may receive the first electronic control components 208a from the first engagement head 1044a. Accordingly, rapid and efficient engagement of the electronic control components 208a, 208b with the bases 204a, 204b may be achieved.
The flow director coupling substation 512 may be positioned downstream of the control component coupling substation 510.
In this regard,
The flow directors 210 may be loaded directly into the vibratory bowl 1110, or a vibratory hopper 1114 may supply the flow directors 210 to the vibratory bowl in the manner described above. In this regard, a component level sensor 1116 may activate vibration of the vibratory hopper 1114 based on the level of the flow directors 210 within the vibratory bowl 1110. The vibratory bowl 1110 may define a pathway 1118 configured to arrange the flow directors 210 in a serially-aligned stream 1120 (see,
The vibratory bowl 1110 may be configured to arrange the flow directors 210 generally vertically by the time the flow directors reach the supply track 1112. An actuator or gap (not shown) may be configured to individually remove or realign the flow directors 210 in the serially-aligned stream 1120 when the flow directors are misaligned in a direction, as discussed above. The supply track 1112 may include a full sensor 1132 configured to detect whether the supply track is full of the flow directors 210 and to thereby turn off the vibration of the vibratory bowl 1110, and a low level sensor 1134 configured to detect when the supply track is running low on the flow directors 210, to active an indicator 1130 (see,
Further, as illustrated in
After the outermost flow director 210 is released from the stop 1138, the flow director may contact a second stop 1144. At this time a second vertical actuator 1146 may extend a guide pin 1148 into the longitudinal hole 210′ extending through the flow director 210. Thus, when a horizontal actuator 1150 retracts the second stop 1144, the flow director 210 may fall down the guide pin 1148. In this regard, the guide pin 1148 may guide the flow director 210 to the feeder unit 1104, such that the flow director is singulated from the serially-aligned stream 1120, and received by the feeder unit 1104.
As illustrated in
Thus, the singulated flow directors 210 may be delivered to the first assembly unit 1106a and the second assembly unit 1106b.
Accordingly, the track 602 may move the carriage 604 such that the first base 204a is positioned for receipt of the first flow director 210a and similarly, the second base 204b is positioned for receipt of the second flow director 210b. In this regard, as illustrated in
Further, the first processing portion 1170a may include a terminal spreader 1184. As illustrated, the terminal spreader 1184 may include first and second spreading pins 1186a, 1186b. In this regard, while the carriage 604 is stopped by the initial stop 1176a, a vertical actuator 1188 of the terminal spreader 1184 may lower the first spreading pin 1186a between the first negative and positive heating terminals 234a, 235a and lower the second spreading pin 1186b between the second negative and positive heating terminals 234b, 235b. Thereby, the negative and positive heating terminals 234, 235 may be spread apart from one another, such that insertion of the flow director 210 therebetween and into engagement with the electronic control component 208 by the first robotic arm 1162a is facilitated.
In this regard, the first and second opposing portions 1166, 1168 of the first end effector 1164a (see,
While the carriage 604 is lifted by the lifter mechanism 1182a, a component presence sensor 1194a (e.g., comprising a light emitter and a receiver) may detect the presence of the flow director 210a. Further, a storage transceiver 1196a may write code to the storage module 624 indicating whether or not the first flow director 210a was properly coupled to the first base 204a based on the signal from the component presence sensor 1194a, such that improperly assembled cartridges may not be subjected to further assembly operations downstream. In this same regard, the storage transceiver 1196a may read the code on the storage module 624 to determine that the partially-assembled cartridge is fit for further assembly prior to coupling the flow director 210a to the base 204a.
Thereafter, the lifter mechanism 1182a may lower the carriage 604 back onto the track 602. The carriage 604 may be directed downstream to the second processing portion 1170b, at which the second assembly unit 1106b may perform substantially the same operations discussed above with respect to the first assembly unit 1106a on the second base 204b, with the exception of terminal spreading which is conducted upstream at the terminal spreader 1184. In this regard, as illustrated in
Note that the above-described operations may be conducted simultaneously. In this regard, while the first engagement head 1154a delivers the first flow director 210a to the first robotic arm 1162a, the second engagement head 1154b may receive the second flow director 210b from the singulator 1136. Conversely, while the second engagement head 1154b delivers the second flow director 210b to the second robotic arm 1162b, the first engagement head 1154a may receive the first flow director 210a from the singulator 1136. Further, while the first robotic arm 1162a couples the first flow director 210a to the first base 204a, the second robotic arm 1162b may receive the second flow director 210b from the second engagement head 1154b. Conversely, while the second robotic arm 1162b couples the second flow director 210b to the second base 204b, the first robotic arm 1162a may receive the first flow director 210a from the first engagement head 1154a. Accordingly, rapid and efficient engagement of the flow directors 210a, 210b with the bases 204a, 204b may be achieved.
The heating element coupling substation 514 may be positioned downstream of the flow director coupling substation 512.
The heating element coupling substation 514 may further include a casing 1208. The casing 1208 may be substantially enclosed and opaque so as to prevent laser beams/and or other potentially harmful light from exiting therefrom. In this regard, as discussed below, welding, and in particular laser welding, in addition to the various other operations discussed below, may be performed inside the casing 1208.
As illustrated in
The supply unit 1202 may be configured to pull the substantially continuous heating element input 1206 until a desired length thereof is received by the feeder unit 1216. In this regard, at least one imaging device may be configured to determine a length of the substantially continuous heating element input 1206 pulled from the spool 1202. As illustrated in
Accordingly, the rotary member 1224 may swivel from the first receiving position at which a singulated heating element 240 and liquid transport element 238 is received to a first delivery position, which corresponds to a second receiving position at which the second arm 1222b of the rotary member 1224 is positioned proximate the supply unit 1202. As illustrated in
As illustrated in
As illustrated, in
In this regard,
Accordingly, the opposing portions 1236, 1238 of the first engagement head 1218a may depress the depressible buttons 1244 while extending around the singulated heating element 240 and liquid transport element 238 received in the first engagement head. The first engagement head 1218a may then clamp onto the singulated heating element 240 and liquid transport element 238. Thus, the first robotic arm 1234a may lift the singulated heating element 240 and liquid transport element 238 received in the first engagement head 1218a and transport the singulated heating element and liquid transport element for assembly with the positive heating terminal 235 and the negative heating terminal 234a coupled to a first base 204a.
In this regard, as illustrated in
Further, the first processing portion 1244a may include a terminal fixation mechanism 1258a and a laser 1260a.
In this regard,
During this clamping operation, a center portion 1272c of the protruding member 1268 may extend between the negative and positive heating terminals 234a, 235a. Further, outer prongs 1274c defined by the recessed member 1270 may extend around the outside of the negative and positive heating terminals 234a, 235a. Accordingly, the center portion 1272c of the protruding member 1268 and the outer prongs 1274c of the recessed member 1270 may position the negative and positive heating terminals 234a, 235a at a fixed spacing corresponding to a desired spacing of the negative and positive heating terminals for attachment of the heating element 240 thereto.
In this regard, the robotic arm 1232a may position the end effector 1234a such that the heating element 240 and the liquid transport element 238 are in proximity to the negative and positive heating terminals 234a, 235a. In particular, a center of a heating portion of the heating element 240 may be aligned with a center of the negative and positive heating terminals 234a, 235a via movement of the robotic arm 1232a. In this regard, as illustrated in
Once aligned, the laser 1260a may weld the heating element 240 to one of the negative heating element 234a and the positive heating element 235a. Then the laser 1260a may weld the heating element 240 to the other of the negative heating element 234a and the positive heating element 235a. For example, the laser 1260a may weld the heating element 240 to the negative heating element 234a and then move to a second position to weld the positive heating element 235a. In this regard, the laser 1260a and the imaging device 1270a may be mounted to a slide 1272a configured to move the laser and the camera between first and second welding positions. Accordingly, the heating element 240 may be welded to the negative and positive heating terminals 234a, 235a, which may thereby indirectly couple the liquid transport element 238 to the negative and positive heating terminals as a result of the heating element being coiled around, or otherwise attached to the liquid transport element.
As illustrated in
A component presence sensor 1278a (e.g., comprising a light emitter and receiver) may detect whether or not the heating element 240 was properly coupled to the negative and positive heating terminals 234a, 235a. For example, the component presence sensor 1278a may detect whether or not the heating element 240 and/or the liquid transport element are present while the carriage 604 is lifted by the lifter mechanism 1256a (see,
After welding at the first processing portion 1244a, the lifter mechanism 1256a (see,
The reservoir and outer body coupling substation 516 may be positioned downstream of the heating element coupling substation 514.
As illustrated, the reservoir supply unit 1304 may include a first spool 1308a and a second spool 1308b each configured to respectively supply a substantially continuous reservoir substrate input 1310. Each spool 1308a, 1308b may supply the substantially continuous reservoir substrate input 1310 to a respective moveable clamp 1312, one of which is illustrated in
At this time a stationary clamp 1320, as illustrated in
A vacuum gripper 1324 (see,
While the singulated reservoir substrates 214 are supplied by the reservoir supply unit 1304 in the manner described above, the outer body supply unit 1306 may supply the outer bodies 216 (see, e.g.,
The vibratory bowl 1330 may define a pathway 1338 configured to arrange the outer bodies 216 in a serially-aligned stream 1340. In this regard, the vibratory motion of the vibratory bowl 1330 may direct the outer bodies 216 upwardly along the pathway 1338, which may narrow such that some outer bodies fall therefrom and the outer bodies that remain on the pathway become serially-aligned. The vibratory bowl 1330 may be configured to arrange the outer bodies 216 generally vertically by the time the outer bodies reach the supply track 1332. An actuator or gap (not shown) may be configured to individually remove or realign the outer bodies in the serially-aligned stream 1340 when the outer bodies are misaligned in a direction, as discussed above with respect to other components. The supply track 1332 may include a full sensor 1342 configured to detect whether the supply track is full of the outer bodies 216 and to thereby turn off the vibration of the vibratory bowl 1330, and a low level sensor (not shown; see, e.g., the full sensor 1342) configured to detect when the supply track 1332 is running low on the outer bodies 216, to active an indicator 1346 (see,
Further, as illustrated in
Accordingly, the feeder unit 1328 may receive one of the outer bodies 216. In this regard, as illustrated in
The beam 1364 may be configured to raise, lower, and shift laterally between a first receiving position, which corresponds to a second delivery position, and a second receiving position, which corresponds to a first delivery position. In this regard, the beam 1364 may lower such that the opposing portions 1366, 1368 of the first engagement head 1362a extend into the upper cutout 1358 in the stop 1350 and clamp onto an outermost outer body 216 in the serially-aligned stream 1340. While the first engagement head 1362a engages a first outer body 216, a second outer body may be delivered to a second outer body and reservoir substrate feeder 1370b, which is illustrated in
Accordingly, the initial outer body feeder 1360 may alternatingly feed outer bodies 216 to the first outer body and reservoir substrate feeder 1370a and the second outer body and reservoir substrate feeder 1370b. While the first outer body and reservoir substrate feeder 1370a receives a first outer body 216 from the initial outer body feeder 1360, the first outer body and reservoir substrate feeder also receives a reservoir substrate 214 singulated from the substantially continuous reservoir input 1310 supplied by the first spool 1308a in the manner described above. Conversely, while the second outer body and reservoir substrate feeder 1370b receives a second outer body 216 from the initial outer body feeder 1360, the second outer body and reservoir substrate feeder also receives a reservoir substrate 214 singulated from the substantially continuous reservoir input 1310 supplied by the second spool 1308b in the manner described above.
In this regard, as illustrated in
Further, as illustrated in
Once the first outer body and reservoir substrate feeder 1370a or the second outer body and reservoir substrate feeder 1370b receives the outer body 216 and the reservoir substrate 214, the rotary member 1372 may rotate such that the reservoir substrate and the outer body are positioned for receipt by a respective one of a first assembly unit 1380a and a second assembly unit 1380b, as illustrated in
In the illustrated embodiment the second assembly unit 1380b is positioned upstream of the first assembly unit 1380a. Accordingly, a reservoir substrate 214 and an outer body 216 may be assembled to the second partially-assembled cartridge including the second base 204b in advance of assembling a reservoir substrate and an outer body to the first partially-assembled cartridge including the first base 204a. However, as may be understood, this order may be reversed in other embodiments.
Accordingly, the carriage 604 may be directed along the track 602 for receipt of the reservoir substrate 214 and the outer body 216. In this regard, as illustrated in
In this regard, as illustrated in
As illustrated in
While the liquid transport element 238 and the heating element 240 are bent against the negative heating terminal 234 and the positive heating terminal 235, the substrate gripper 1374′ may wrap the reservoir substrate 214 at least partially around the bending mechanism 1398. In this regard, as illustrated in
As illustrated in
While the robotic arm 1396 lowers the bending mechanism 1398 over the partially-assembled cartridge, the outer body gripper 1400 may also be lowered such that the first and second opposing portions 1402′, 1402″ extend around an outer body 216 supported by the one of the outer body supporters 1376′, 1376″ positioned proximate the track 602. Accordingly, the outer body gripper 1440 may be configured to receive the outer body 216 therein while the bending mechanism 1398 receives the partially-assembled cartridge therein. Once lowered, the first and second opposing portions 1402′, 1402″ may move toward one another such that the outer body gripper 1400 retains the outer body 216 therein. Thus, when the robotic arm 1396 lifts the bending mechanism 1398 after the reservoir substrate 214 is wrapped thereabout, the outer body gripper 1400 may lift the outer body 216 from the one of the outer body supporters 1376′, 1376″ to which the outer body was engaged.
Further, the robotic arm 1396 may direct the outer body gripper 1400 with the outer body 216 positioned therein over the partially-assembled cartridge. In this regard, the robotic arm 1396 may rotate (e.g., about 90 degrees) such that the bending mechanism 1398 is positioned away from the carriage 604, and thereby does not come into contact with the carriage, while the outer body gripper 1400 extends downwardly toward the partially-assembled cartridge. As the outer body 216 is directed over the partially-assembled cartridge, at least a portion of the negative heating terminal 234, the positive heating terminal 235, the heating element 240, and the liquid transport element 238, and the electronic control component 208 and the control component terminal 206 in embodiments including these components) are received in the outer body.
In order to facilitate insertion of the partially-assembled cartridge into the outer body 216, the outer body gripper 1400 may apply a negative pressure longitudinally through the outer body via the outer body gripper 1400. In this regard, as illustrated in
As the outer body 216 is pressed downwardly over the partially-assembled cartridge, the opposing portions 1378′, 1378″ of the substrate gripper 1374′ may release the reservoir substrate 214, and cease applying negative pressure thereto in embodiments in which the substrate gripper applies negative pressure to the reservoir substrate. The rotary member 1372 of the outer body and reservoir substrate feeder 1370b may then swivel (e.g., by rotating about one hundred and eighty degrees) to transport an additional outer body 216 into proximity to the robotic arm 1396 for attachment to a partially-assembled cartridge on the next carriage 604.
The piston 1404 may be further configured to press the outer body 216 into engagement with the base 204b. In this regard, the piston 1404 may press against an upper end of the outer body 216 (e.g., by sitting flush against the upper end of the outer body). In this regard, the piston 1404 may define one or dimensions (e.g., a diameter) that are substantially equal to that of the outer body 216. Thereby, the outer body 216 may be pressed over the partially-assembled cartridge into full engagement with the base 204b.
A component presence sensor 1406b (e.g., comprising a light emitter and receiver) may detect whether or not the outer body 216 was properly coupled to the base 204b. For example, the component presence sensor 1406b may detect whether or not the outer body 216 is present while the carriage 604 is lifted by the lifter mechanism 1394b. Thereby, this information may be written to the storage module 624 by a storage transceiver (not shown; see, e.g., storage transceiver 1408a) at the second processing portion 1382b. Thus additional operations may not be performed on the partially-assembled cartridge if the outer body 216 is not properly assembled therewith, so as to avoid damage to the assembly equipment and waste of additional components. In this same regard, the storage transceiver may read the code on the storage module 624 to determine that the partially-assembled cartridge is fit for further assembly prior to coupling the outer body 216 to the base 204.
Once the outer body 216 is pressed onto the partially-assembled cartridge, the lifter mechanism 1394b may lower the carriage back onto the track 602. The carriage 604 may then be directed to the first processing portion 1382a, at which substantially the same operations may occur to couple a first outer body 216 to the first base 204a. Thereafter, as described above with respect to the second processing portion 1382b, a component presence sensor 1406a (e.g., comprising a light emitter and receiver) may detect whether or not the outer body 216 was properly coupled to the base 204a. Thereby, this information may be written to the storage module 624 by a storage transceiver 1408a at the first processing portion 1382a. Thus additional operations may not be performed on the partially-assembled cartridge if the outer body 216 is not properly assembled therewith, so as to avoid damage to the assembly equipment and waste of additional components. In this same regard, the storage transceiver 1408a may read the code on the storage module 624 to determine that the partially-assembled cartridge is fit for further assembly prior to coupling the outer body 216 to the base 204.
Note that the above-described operations may be conducted simultaneously. In this regard, for each of the outer body and reservoir substrate feeders 1370a, 1370b, while one of the substrate grippers 1374′, 1374″ receives a reservoir substrate 1314, the other of the substrate grippers may wrap the reservoir substrate around the bending mechanism 1398. Further, while one of the substrate grippers 1374′, 1374″ receives a reservoir substrate 1314, an associated one of the outer body supporters 1376′, 1376″ may receive an outer body. Various other operations conducted by the reservoir and outer body coupling substation 516 may be conducted simultaneously so as to reduce cycle times. Accordingly, rapid and efficient engagement of the reservoir substrate and outer body with the partially-assembled cartridges may be achieved. The outer body crimping and inspection substation 518 may be positioned downstream of the reservoir and outer body coupling substation 516.
In this regard,
Thus, the carriage 604 may be lifted at each of the first crimper unit 1502a and the second crimper unit 1502b by the respective lifter mechanism 1524. While lifted at the first crimper unit 1502a the first outer body 216 may be crimped onto the first base 204a. Similarly, while lifted at the second crimper unit 1502b the second outer body 216 may be crimped onto the second base 204b.
After each crimping operation a component presence sensor 1526 (e.g., comprising a light emitter and receiver) may detect whether the partially-assembled cartridge that was crimped is still present. Thereby, a storage transceiver 1528 may write code to the storage module 624 indicating whether or not the partially-assembled cartridge subjected to the crimping operation is present, so that additional operations may not be performed thereon when the cartridge is not detected. In this same regard, the storage transceiver 1528 may read the code on the storage module 624 to determine that the partially-assembled cartridge is fit for further assembly prior to crimping the outer body 216 to the base 204. Thereafter, the lifter mechanism 1524 may lower the carriage 604 into engagement with the track 602 such that the carriage is directed downstream. In this regard, each carriage 604 may be directed from the first crimper unit 1502a to the second crimper unit 1502b to the first transfer unit 1504.
In this regard, as further illustrated in
The processing portion 1530 of the first transfer unit 1504 may further comprise a first component presence sensor 1548a and a second component presence sensor 1548b (e.g., respectively comprising a light emitter and receiver). The first component presence sensor 1548a may be configured to detect whether the first partially-assembled cartridge is successfully removed from the carriage by the robotic arm 1546 and the end effector 1540. Similarly the second component presence sensor may be configured to determine whether the second partially-assembled cartridge is removed by the robotic arm 1546 and the end effector 1540. Thereby, a storage transceiver 1542 may write code to the storage module 624 indicating whether or not the partially-assembled cartridges are successfully removed from the carriage 604. In this regard, when the partially-assembled cartridges are successfully removed from the carriage 604, the track 602 may direct the carriage back to the staging area 602a, such that the carriage may be reused with each of the substations 502-518 (see,
The first transfer unit 1504 may transfer the partially-assembled cartridges to the inspection and processing unit 1506. As illustrated in
The first transfer unit 1504 may transfer the remainder of the partially-assembled cartridges, which are not directed to the audit chute 1547 to an indexing table 1550 of the inspection and processing unit 1506. As illustrated, the indexing table 1550 may include a plurality of first grippers 1552a and second grippers 1552b extending radially therefrom. The first grippers 1552a may be configured to receive the first partially-assembled cartridges and the second grippers 1552b may be configured to receive the second partially-assembled cartridges. Thereby, as the indexing table 1550 indexes (e.g., by moving counterclockwise in terms of the illustrated orientation), the partially-assembled cartridges may be transported between a plurality of angular stops.
In this regard, the first transfer unit 1504 may transport the partially-assembled cartridges to a first angular stop 1554. As illustrated in
Conversely, when a partially-assembled cartridge is not determined to be defective, the associated gripper 1552a, 1552b to which the partially-assembled cartridge is delivered may clamp onto the cartridge such that the cartridge may be transported with movement of the indexing table 1550. In this regard, each gripper 1552a, 1552b may include first and second opposing portions 1558, 1560 configured to clamp around the base 204 and/or the outer body 216 of each partially-assembled cartridge. Each gripper 1552a, 1552b may be actuated in response to a respective component presence sensor 1562a, 1562b detecting the presence of a partially-assembled cartridge at the gripper, and which has not been previously determined to be defective as described above. Note that in
Once received in the grippers 1552a, 1552b, the indexing table 1550 may index such that the partially-assembled cartridges are transported to a second angular stop 1564.
After the air flow assemblies 1566 release from the partially-assembled cartridges, the indexing table 1550 may index to a third angular stop 1572. As illustrated in
The indexing table 1550 may next index to a fourth angular stop 1578. As illustrated in
The indexing table 1550 may then index to a fifth angular stop 1582. As illustrated in
The indexing table 1550 may further index to a sixth angular stop 1586, which corresponds to a position at which the partially-assembled cartridges are proximate the second transfer unit 1508. In this regard, as illustrated in
Note that the inspection subsystem 418 may be distributed across the various portions of the system 400 for producing cartridges. In this regard, by way of example, the inspection subsystem 418 may include the various component presence sensors and other sensors configured to detect the position, presence, and other attributes of the components of the cartridge as described above.

Swiveling the rotary member may include receiving one of the components from the supply unit in a first engagement head while a second engagement head feeds one of the components to the second assembly unit and receiving one of the components from the supply unit in the second engagement head while the first engagement head feeds one of the components to the first assembly unit.

The method may further include storing cartridge identification and status information in a storage module coupled to the carriage. Additionally, the method may include locking the carriage at one or more of the substations by directing one or more locking pins from the track into one or more alignment apertures defined in the carriage. Transporting the carriage by way of the track at operation 1708 may include transporting the carriage by way of a conveyor, and wherein locking the carriage comprises lifting the carriage from the conveyor.
In some embodiments the method may further include inserting the partially-assembled cartridge in a bending mechanism to bend the liquid transport element against the negative heating terminal and the positive heating terminal, wrapping a reservoir substrate at least partially around the bending mechanism, and retracting the bending mechanism relative to the partially-assembled cartridge following wrapping of the reservoir substrate such that the reservoir substrate is wrapped at least partially about the negative heating terminal and the positive heating terminal and in contact with the liquid transport element. Applying the negative pressure to the outer body at operation 1806 may include engaging an end of the outer body with a piston of the outer body gripper, the piston being in fluid communication with the suction system and configured to apply the negative pressure through the outer body. Further, the method may include pressing the outer body into engagement with the base with the piston.
As noted above, the system 400 may include a controller 417. The controller 417 may be configured to execute computer code for performing the operations described herein. As illustrated in
The controller 417 may also include a user interface 1906 that allows a user to interact therewith. For example, the user interface 1906 can take a variety of forms, such as a button, keypad, dial, touch screen, audio input interface, visual/image capture input interface, input in the form of sensor data, etc. Still further, the user interface 1906 may be configured to output information to the user through a display, speaker, or other output device. A communication 1908 interface may provide for transmitting and receiving data through, for example, a wired or wireless network 1910 such as a local area network (LAN), a metropolitan area network (MAN), and/or a wide area network (WAN), for example, the Internet.
