The foregoing, and other features and advantages of the invention, will be apparent from the following, more particular description of the preferred embodiments of the invention, the accompanying drawings, and the claims.
These and other features, aspects, and advantages are described below with reference to the drawings, which are intended to illustrate, but not to limit, the invention. In the drawings, like characters denote corresponding features consistently throughout similar embodiments.
“Heat-staking” is a manufacturing process by which two or more working components are assembled at an elevated (“working”) temperature, and then allowed to cool and solidify. For instance, some manufactured components, such as polymer (e.g., thermoplastic) components, produced via processes such as rapid prototyping and injection-molding, can include metallic, heat-set threaded inserts (also referred to herein as “threaded inserts”) to enhance thread strength. These threaded inserts, and associated methods of their installation within working components, are common in industrial manufacturing. Typical threaded-insert installation involves heating and pressing the threaded insert into a cavity defined by the working component. Currently available threaded-insert-installation equipment ranges from standard, hand-held soldering irons (e.g., with unmodified tips), to industrial-grade machines with custom heating elements, to some fully automated equipment capable of installing multiple threaded inserts simultaneously.
This disclosure describes example systems, devices, and techniques for installing and securing threaded inserts within working components, such as polymer (e.g., thermoplastic) components. In some examples described herein, a heat-staking device, such as a threaded-insert installer, includes a temperature controller, a base, an upright, and an adjustable-height head containing a quill to vertically move a heater assembly and at least one thermal-installation tip. Some such examples further include a handle and a linkage configured to amplify the user's input force applied to the threaded insert.
The examples described herein provide novel benefits over typical, currently available threaded-insert-installation machines. For instance, the examples described herein enable a user to rapidly exchange thermal-installation tips (e.g., different-sized installation tips for different-sized threaded inserts) even while the installation tips are still hot, and without requiring additional tools. For instance, in some examples, a threaded-insert installer includes a rapid-exchange mechanism in which the tip holder defines a helical slot configured to receive the affixed pin that extends from the thermal installation tip. These example rapid-exchange mechanisms also provide for a lowered thermal mass, thereby enabling faster heating up to the desired working temperature.
Some examples described herein further provide a common access location enabling a user to quickly and easily adjust multiple parameters (e.g., top and bottom stroke limits of the vertical quill). Additionally, or alternatively, some examples include a heat-resistant case enabling a user to readily identify, exchange, organize, and store a plurality of thermal-installation tips while the tips are still hot.
As mentioned previously, the handle 200 may be configured to move various components of the head 106, including, by way of the quill clamp 310, the quill 302. The handle 200 may also impart a mechanical advantage and cause vertical motion of other elements coupled (directly or indirectly) to the quill 302, such as the soldering iron 308 and the insulating tip holder 304, which may both be disposed within the quill 302, as well as the thermal-installation tip 306. Accordingly, when the handle 200 is in the “up” position as shown in
The ability to adjust the vertical position of the head 106 with respect to the base 102 may enable the heat-staking device 100 to be used for several types and/or sizes of working components. For example, with the threaded insert tray 108 shown in
It is important to consider not only the location of the head 106 along the upright arm 104 but also the position of the handle 200 when the vertical height is set (i.e., by securing the clamp 402 to the channel 404 of at least one of the plurality of sides 400 of the upright arm 104). Because the handle 200 causes vertical motion of the quill 302, and, therefore, vertical motion of the thermal-installation tip 306, if the head 106 is secured too low (i.e., too close to the surface 406) with the handle 200 in the “up” position, once the handle 200 is moved to lower the quill 302, the thermal-installation tip 306 may prematurely contact the working component.
Though illustrated with a substantially square cross-section and a rectangular shape, it should be noted that the upright arm 104 may define any number of shapes. For example, the upright arm 104 may comprise a circular cross-section and an overall cylindrical shape. In such an embodiment, the head 106 may be shaped, sized, and arranged to receive a cylindrical upright arm 104 so that the clamp 402 is still able to secure the head 106 to the upright arm 104. Any number of suitable shapes may be possible for the upright arm 104.
The top quill stop 600a may be configured to define a maximum vertical position of the quill 302 by sliding vertically on the threaded rod 602 coupled to the main head unit 300. Similarly, the bottom quill stop 600b may be configured to define a minimum vertical position of the quill 302 by sliding vertically along the threaded rod 602. Each of the top quill stop 600a and the bottom quill stop 600b may comprise educated nuts configured to move helically along the threaded rod 602. The quill stops 600a, 600b may both be positioned at a common access location for convenient adjustment by the user of the heat-staking device 100.
In some embodiments, the pin 702 and the tip holder helical slot 700 enable rapid-exchange of the thermal-installation tip 306, while also resisting an undesired downward axial force that might otherwise be encountered during the installation of threaded inserts into a working component. As shown in
The method may continue with inserting a second end of the thermal-installation tip 306 into the open end of the insulating tip holder 304, at step 1206. In some embodiments, the second end of the thermal-installation tip 306 is located opposite the first end. The first end may be considered the “working end,” or the end of the thermal-installation tip that makes contact with a threaded insert. The method may continue by aligning the pin 702 with the tip holder helical slot 700, at step 1208. Next, the method may involve rotating the tool 800 to engage the pin 702 with the tip holder helical slot 700 and disengage the pin 702 from the tool helical slot 802, at step 1210. This rotation may again include a one-quarter turn of the tool 800, but in a second direction that is opposite the first direction (e.g., clockwise vs. counterclockwise or vice versa).
In some embodiments, the method continues by heating the thermal-installation tip 306, at step 1212. As discussed previously, the thermal-installation tip 306 may be heated by a soldering iron 308 located inside the quill 302 near the insulating tip holder 304. The method may finish by lowering, via the handle 200, the thermal-installation tip 306 into a threaded insert to heat and install the threaded insert, at step 1214. The process may be repeated in reverse to remove the thermal-installation tip 306 from the insulating tip holder 304, storing it, for example, in the case 1100, and starting the process again at step 1200 with a different-sized thermal-installation tip 306. Using the tool 800 and the case 1100 may enable a user to quickly change out thermal-installation tips 306 even while the tips are still hot because the tool 800 substantially reduces the risk of direct contact with the hot thermal-installation tip 306 and the heat-resistant case 1100 enables safe storage. The ability to quickly swap out thermal-installation tips 306 may increase the speed and efficiency of the heat-staking process.
Though not illustrated in the Figures, the heat-staking device 100 may include an integrated control system configured to operate the device 100, control the temperature of the soldering iron 308, set a timer with an automatic heat shut-off, and any number of other possible operations. The integrated control system may be a separate control unit (e.g., with a remote control) electrically and communicatively coupled to the heat-staking device, or it may comprise a control panel integrated into the housing of the device 100, such as in/on the head 106. In some embodiments, the heat-staking device 100 is configured to be compatible with a third-party control system.
None of the steps described herein is essential or indispensable. Any of the steps can be adjusted or modified. Other or additional steps can be used. Any portion of any of the steps, processes, structures, and/or devices disclosed or illustrated in one embodiment, flowchart, or example in this specification can be combined or used with or instead of any other portion of any of the steps, processes, structures, and/or devices disclosed or illustrated in a different embodiment, flowchart, or example. The embodiments and examples provided herein are not intended to be discrete and separate from each other.
The section headings and subheadings provided herein are nonlimiting. The section headings and subheadings do not represent or limit the full scope of the embodiments described in the sections to which the headings and subheadings pertain. For example, a section titled “Topic 1” may include embodiments that do not pertain to Topic 1 and embodiments described in other sections may apply to and be combined with embodiments described within the “Topic 1” section.
The various features and processes described above may be used independently of one another, or may be combined in various ways. All possible combinations and subcombinations are intended to fall within the scope of this disclosure. In addition, certain method, event, state, or process blocks may be omitted in some implementations. The methods, steps, and processes described herein are also not limited to any particular sequence, and the blocks, steps, or states relating thereto can be performed in other sequences that are appropriate. For example, described tasks or events may be performed in an order other than the order specifically disclosed. Multiple steps may be combined in a single block or state. The example tasks or events may be performed in serial, in parallel, or in some other manner. Tasks or events may be added to or removed from the disclosed example embodiments. The example systems and components described herein may be configured differently than described. For example, elements may be added to, removed from, or rearranged compared to the disclosed example embodiments.
Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without author input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular embodiment. The terms “comprising,” “including,” “having,” and the like are synonymous and are used inclusively, in an open-ended fashion, and do not exclude additional elements, features, acts, operations and so forth. Also, the term “or” is used in its inclusive sense (and not in its exclusive sense) so that when used, for example, to connect a list of elements, the term “or” means one, some, or all of the elements in the list. Conjunctive language such as the phrase “at least one of X, Y, and Z,” unless specifically stated otherwise, is otherwise understood with the context as used in general to convey that an item, term, etc. may be either X, Y, or Z. Thus, such conjunctive language is not generally intended to imply that certain embodiments require at least one of X, at least one of Y, and at least one of Z to each be present.
The term “and/or” means that “and” applies to some embodiments and “or” applies to some embodiments. Thus, A, B, and/or C can be replaced with A, B, and C written in one sentence and A, B, or C written in another sentence. A, B, and/or C means that some embodiments can include A and B, some embodiments can include A and C, some embodiments can include B and C, some embodiments can only include A, some embodiments can include only B, some embodiments can include only C, and some embodiments can include A, B, and C. The term “and/or” is used to avoid unnecessary redundancy.
The term “substantially” is used to mean “completely” or “nearly completely.” For example, the disclosure includes the following: “Though illustrated with a substantially square cross-section . . . . ” In this context, a “substantially square cross-section” is used to mean a “completely” or “nearly completely” square cross-section, and does not require a 100% perfectly square cross-section.
The term “adjacent” is used to mean “next to or adjoining.” For example, the disclosure includes the following: “. . . quill stop coupled to the main head unit adjacent the handle . . . . ” In this context, “adjacent the handle” is used to mean that the quill stop is next to or adjoining the handle.
The foregoing (e.g., a control system for the heat-staking device) may be accomplished through software code running in one or more processors on a communication device in conjunction with a processor in a server running complementary software code.
Some of the devices, systems, embodiments, and processes use computers. Each of the routines, processes, methods, and algorithms described in the preceding sections may be embodied in, and fully or partially automated by, code modules executed by one or more computers, computer processors, or machines configured to execute computer instructions. The code modules may be stored on any type of non-transitory computer-readable storage medium or tangible computer storage device, such as hard drives, solid state memory, flash memory, optical disc, and/or the like. The processes and algorithms may be implemented partially or wholly in application-specific circuitry. The results of the disclosed processes and process steps may be stored, persistently or otherwise, in any type of non-transitory computer storage such as, e.g., volatile or non-volatile storage.
It is appreciated that in order to practice the method of the foregoing as described above, it is not necessary that the processors and/or the memories of the processing machine be physically located in the same geographical place. That is, each of the processors and the memory (or memories) used by the processing machine may be located in geographically distinct locations and connected so as to communicate in any suitable manner. Additionally, it is appreciated that each of the processor and/or the memory may be composed of different physical pieces of equipment. Accordingly, it is not necessary that the processor be one single piece of equipment in one location and that the memory be another single piece of equipment in another location. That is, it is contemplated that the processor may be two pieces of equipment in two different physical locations. The two distinct pieces of equipment may be connected in any suitable manner. Additionally, the memory may include two or more portions of memory in two or more physical locations.
To explain further, processing, as described above, is performed by various components and various memories. However, it is appreciated that the processing performed by two distinct components as described above may, in accordance with a further embodiment of the foregoing, be performed by a single component. Further, the processing performed by one distinct component as described above may be performed by two distinct components. In a similar manner, the memory storage performed by two distinct memory portions, as described above, may, in accordance with a further embodiment of the foregoing, be performed by a single memory portion. Further, the memory storage, performed by one distinct memory portion, as described above, may be performed by two memory portions.
Further, various technologies may be used to provide communication between the various processors and/or memories, as well as to allow the processors and/or the memories of the foregoing to communicate with any other entity, i.e., so as to obtain further instructions or to access and use remote memory stores, for example. Such technologies used to provide such communication might include a network, the Internet, Intranet, Extranet, LAN, an Ethernet, wireless communication via cell tower or satellite, or any client server system that provides communication, for example. Such communications technologies may use any suitable protocol such as TCP/IP, UDP, or OSI, for example.
As described above, a set of instructions may be used in the processing of the foregoing. The set of instructions may be in the form of a program or software.

Further, it is appreciated that the instructions or set of instructions used in the implementation and operation of the foregoing may be in a suitable form such that the processing machine may read the instructions. For example, the instructions that form a program may be in the form of a suitable programming language, which is converted to machine language or object code to allow the processor or processors to read the instructions. That is, written lines of programming code or source code, in a particular programming language, are converted to machine language using a compiler, assembler or interpreter. The machine language is binary coded machine instructions that are specific to a particular type of processing machine, i.e., to a particular type of computer, for example. The computer understands the machine language.
Any suitable programming language may be used in accordance with the various embodiments of the foregoing. Illustratively, the programming language used may include assembly language, Ada, APL, Basic, C, C++, COBOL, dBase, Forth, Fortran, Java, Modula-2, Pascal, Prolog, Python, REXX, Visual Basic, and/or JavaScript, for example. Further, it is not necessary that a single type of instruction or single programming language be utilized in conjunction with the operation of the system and method of the foregoing. Rather, any number of different programming languages may be utilized as is necessary and/or desirable.
Also, the instructions and/or data used in the practice of the foregoing may utilize any compression or encryption technique or algorithm, as may be desired. An encryption module might be used to encrypt data. Further, files or other data may be decrypted using a suitable decryption module, for example.
As described above, the foregoing may illustratively be embodied in the form of a processing machine, including a computer or computer system, for example, that includes at least one memory. It is to be appreciated that the set of instructions, i.e., the software for example, that enables the computer operating system to perform the operations described above may be contained on any of a wide variety of media or medium, as desired. Further, the data that is processed by the set of instructions might also be contained on any of a wide variety of media or medium. That is, the particular medium, i.e., the memory in the processing machine, utilized to hold the set of instructions and/or the data used in the foregoing may take on any of a variety of physical forms or transmissions, for example. Illustratively, the medium may be in the form of paper, paper transparencies, a compact disk, a DVD, an integrated circuit, a hard disk, a floppy disk, an optical disk, a magnetic tape, a RAM, a ROM, a PROM, an EPROM, a wire, a cable, a fiber, a communications channel, a satellite transmission, a memory card, a SIM card, or other remote transmission, as well as any other medium or source of data that may be read by the processors of the foregoing.
Further, the memory or memories used in the processing machine that implements the foregoing may be in any of a wide variety of forms to allow the memory to hold instructions, data, or other information, as is desired. Thus, the memory might be in the form of a database to hold data. The database might use any desired arrangement of files such as a flat file arrangement or a relational database arrangement, for example.
In the system and method of the foregoing, a variety of “user interfaces” may be utilized to allow a user to interface with the processing machine or machines that are used to implement the foregoing. As used herein, a user interface includes any hardware, software, or combination of hardware and software used by the processing machine that allows a user to interact with the processing machine. A user interface may be in the form of a dialogue screen for example. A user interface may also include any of a mouse, touch screen, keyboard, keypad, voice reader, voice recognizer, dialogue screen, menu box, list, checkbox, toggle switch, a pushbutton or any other device that allows a user to receive information regarding the operation of the processing machine as it processes a set of instructions and/or provides the processing machine with information. Accordingly, the user interface is any device that provides communication between a user and a processing machine. The information provided by the user to the processing machine through the user interface may be in the form of a command, a selection of data, or some other input, for example.
As discussed above, a user interface is utilized by the processing machine that performs a set of instructions such that the processing machine processes data for a user. The user interface is typically used by the processing machine for interacting with a user either to convey information or receive information from the user. However, it should be appreciated that in accordance with some embodiments of the system and method of the foregoing, it is not necessary that a human user actually interact with a user interface used by the processing machine of the foregoing. Rather, it is also contemplated that the user interface of the foregoing might interact, i.e., convey and receive information, with another processing machine, rather than a human user. Accordingly, the other processing machine might be characterized as a user. Further, it is contemplated that a user interface utilized in the system and method of the foregoing may interact partially with another processing machine or processing machines, while also interacting partially with a human user.
While certain example embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the inventions disclosed herein. Thus, nothing in the foregoing description is intended to imply that any particular feature, characteristic, step, module, or block is necessary or indispensable. Indeed, the novel methods and systems described herein may be embodied in a variety of other forms; furthermore, various omissions, substitutions, and changes in the form of the methods and systems described herein may be made without departing from the spirit of the inventions disclosed herein.
