Example embodiments will be described in more detail with regard to the attached drawings, in which:
One or more example embodiments will be described in detail with reference to the accompanying drawings. Example embodiments, however, may be embodied in various different forms, and should not be construed as being limited to only the illustrated embodiments. Rather, the illustrated embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the concepts of this disclosure to those skilled in the art. Accordingly, known processes, elements, and techniques, may not be described with respect to some example embodiments. Unless otherwise noted, like reference characters denote like elements throughout the attached drawings and written description, and thus descriptions will not be repeated.
Although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and/or sections, these elements, components, regions, layers, and/or sections, should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section, from another region, layer, or section. Thus, a first element, component, region, layer, or section, discussed below may be termed a second element, component, region, layer, or section, without departing from the scope of this disclosure.
Spatially relative terms, such as “beneath,” “below,” “lower,” “under,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below,” “beneath,” or “under,” other elements or features would then be oriented “above” the other elements or features. Thus, the example terms “below” and “under” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. In addition, when an element is referred to as being “between” two elements, the element may be the only element between the two elements, or one or more other intervening elements may be present.
As used herein, the singular forms “a,” “an,” and “the,” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising.” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups, thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. Also, the term “exemplary” is intended to refer to an example or illustration.
When an element is referred to as being “on,” “connected to,” “coupled to,” or “adjacent to,” another element, the element may be directly on, connected to, coupled to, or adjacent to, the other element, or one or more other intervening elements may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” “directly coupled to,” or “immediately adjacent to,” another element there are no intervening elements present.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and/or this disclosure, and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Example embodiments may be described with reference to acts and symbolic representations of operations (e.g., in the form of flow charts, flow diagrams, data flow diagrams, structure diagrams, block diagrams, etc.) that may be implemented in conjunction with units and/or devices discussed in more detail below. Although discussed in a particularly manner, a function or operation specified in a specific block may be performed differently from the flow specified in a flowchart, flow diagram, etc. For example, functions or operations illustrated as being performed serially in two consecutive blocks may actually be performed simultaneously, or in some cases be performed in reverse order.
Units and/or devices (e.g., control units, display controller units, etc.) according to one or more example embodiments may be implemented using hardware, software, and/or a combination thereof. For example, hardware devices, such as the processor 210, may be implemented using processing circuitry such as, but not limited to, a processor, Central Processing Unit (CPU), a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a System-on-Chip (SoC), a programmable logic unit, a microprocessor, or any other device capable of responding to and executing instructions in a defined manner.

Although described with reference to specific examples and drawings, modifications, additions and substitutions of example embodiments may be variously made according to the description by those of ordinary skill in the art. For example, the described techniques may be performed in an order different with dial of the methods described, and/or components such as the described system, architecture, devices, circuit, and the like, may be connected or combined to be different from the above-described methods, or results may be appropriately achieved by other components or equivalents.
At least some example embodiments provide use of a container, box and/or tray box (hereinafter referred to as a container) suitable for being handled in an automatic manner (e.g., by the actuator/robot of an automatic Surface Mount Device (SMD) warehouse discussed herein). The container may be configured to have the same or substantially the same geometry and/or dimensions as a “normal” tray and/or component tape reel, such that the container may be fetched by the actuator/robot.

The display controller unit may optionally recognize and register components placed in the container (e.g., by scanning barcodes or RFID tags attached to the containers). The scanning may be performed manually by a handheld barcode tag/RFID tag scanner or by a barcode tag/RFID tag scanner integrated in a SMD warehouse. Alternatively the display controller unit is configured to communicate data (e.g., identities of recognize and register containers) via a communications network to the SMT information database (e.g., such that information on the content of the container is available in the SMT information database). Alternatively, the container is provided with a plurality of separate compartments, sections or cells adapted to each at least one of components without a component reel (e.g. components in plastic bags, tools, fixtures, printed circuit boards or board support), and wherein the display controller is configured to receive data via the communications network from the SMT information database. The container may be provided with a number of separate positions for storing components without a component reel (e.g. components in plastic bags, tools, fixtures, printed circuit boards and board support). In at least one example embodiment, these positions are defined by separate compartments, or sections or cells, one for each component, the compartments being separated by intermediate walls, or the like. Thus, set of components without a component reel (e.g. components in plastic bags, tools, fixtures, printed circuit boards or board support) is effectively kept in place and the component holders carried by the same carrier will not interfere with one another.

In response to receiving the bill of materials/SMT job data 1910, the automated SMD warehouse 1912 automatically delivers bin load units 1914 (e.g., in the form of any bin load unit). In this example, the bin load units 1914 may be in the form of component tape reels and/or containers. Typically, the bin load units delivered from the automated SMD warehouse 1912 are already in the correct order for loading into bins. An SMT operator (e.g., a human being or alternatively a robot) then retrieves the bin load units that are delivered from said automated SMD warehouse 1912, and possibly also substrates from separate storage or from said automated SMD warehouse 1912. In this example, the SMT operator retrieves component tape reels and/or containers from the automated SMD warehouse 1912, and prepares the component tape reels and/or containers for loading into the pick and place machine 1924.
The SMT operator places the one or more associated component pairs into a bin 1920. The bin may, for example, correspond to any bin discussed herein. When a bin is ready, the SMT operator places/loads the bin in the pick and place machine 1924. The pick and place machine 1924 may correspond to the pick and place machine 91 shown in
In order for the pick and place machine 1924 to know which settings are to be used, SMT job data from the planning step is provided to the pick and place machine 1924, either directly from the planning tool or by the SMT operator scanning the barcode of a work order 1922, using a scanner 1918, comprising the required information/SMT job data. This is illustrated in mote detail in
Based on the input SMT job data, machine programs are selected automatically, as are conveyor width and loader/unloader settings. In other words, for example, loading into the pick and place machine 1924 is faster and easier for the SMT operator as it requires no manual data entry—just one or two scans of barcodes or other identifiers. As soon as the line is up and running, the SMT operator is free to start preparing the next SMT job. Also, as all bins and feeders are given a unique ID, the SMT operator may check quantity, location, MSD data and batch codes, for a single component or a complete component list for an SMT job, at any point during production.
If, at any time, components are about to run out, the machine alerts the operator, re-optimizes and continues mounting other components. The SMT operator dial notices such an alert may, for example, press a “provide” button or the like, whereby the SMD warehouse 1912 immediately delivers the requested components) 1914 for the SMT operator to retrieve, associate and load into the pick and place machine 1924 to replenish the machine. This is illustrated in more detail in
One or more example embodiments may also have a plug-and-play simplicity, which means that the SMT operator may load and unload bins in seconds, saving operator time. Specially designed software automatically recognizes the presence, absence and location of components, which means that there is no need to program pick positions and production does not stop if a bin runs out of parts.

The obtained identification information may be provided to an ESL server, thereby enabling the ESL system (IR-based or RFID-based) to readily perform inventory of container stored at storage positions/shelves, push down to the ESL tags (e.g., a display touch screen an electronic dynamic label) on the shelf edges associated with a stored container and (dynamically through event-triggered automatic pushed down instructions) change SMT job related information on the displays. Therefore, it is possible to effectively manage and trace containers, and thereby decrease costs for managing human resources.
E-label tags/electronic displays, according to one or more example embodiments, display shelf location content in form of SMT job related information similar to smart labels on shelves for easy component tape fetching. An IR-based or RFID-based Electronic Shop/Shelf Label (ESL) system may be used to provide (e.g., dynamically/automatically changing) the SMT job related information (from the SMT information database) on the displays (e.g., during a kitting process, a replenishment process, when loading a bin with containers in preparation of a pick-and-place job).
The above ESL, where the SMT operator preparing SMT pick-and-place jobs have an input possibility on (or associated with) an external display unit, where the input mechanism may be one or several buttons (mechanical, electrical or optical) or a touch screen on the display itself, and where the internal action of the operator may be at least one of: direct sending a button pressed message to a controlling system (base station and related software, the SMT information database via an IR and/or RFID-based ESL system); saving the button pressed message to be available at the next scheduled communication event; and directly triggering a display content change (e.g., between given or, alternatively, desired or defined messages).
The e-labels may be configured to (dynamically/automatically) change their appearance to clearly indicate to the SMT job operator where to pick the needed components for an upcoming SMT pick-and-place job (e.g., based on pushed down instructions from the SMT information database using or via a separate ESL system or the operator's pushing of a button). For example, the electronic displays may dynamically change from dark to bright, change color, and indicate in which order the containers and/or boxes (bin load units) shall be more optimally fetched by the operator from the shelves or stored in compartments of a bin (for storing containers).
The electronic labels shown in
The e-labels shown in
The shelves for storing containers (e.g., “bin load units” in form of packets), where at least one electronic label/tag is attached to a shelf edge for each storage location on each shelf.
According to at least some example embodiments, the technology disclosed allows for the use of at least one sensor/detector for detecting/indicating when/whether a container is fetched from (or stored at) the storage location on the shelf (by the operator or a robot) and send uplink information to the ESL system (to be forwarded to SMT information database system), or send it directly to the conventional SMT information database system.
By using modern electronic paper (e-paper) labels information about the various phases during material handling will be displayed just in front of the operator when he/she needs the information.
With the smart e-labels it is possible to show an operator what to do independently if the bin is in the machine or in the kitting area.
At least one other example embodiment provides a smart barcode scanner display configured to display SMT job related information (e.g., direct instructions to the operator) when scanning a barcode (e.g., on a container, a component tape reel, a pallet for carrying a container or component tape reel, or an electronic shelf label/display) during, for example, a kitting process, a replenishment process, when loading a bin with containers in preparation of a pick-and-place job, etc.
Referring to
The smart barcode scanner 3000 with the display 3020 may be used to display SMT job related information to the SMT operator in order to guide the operator on what to do with an object (e.g., a container) corresponding to the scanned barcode. This enhancement to the material handling process by the provision of guidance to the operator (e.g., sequentially provided and/or event-based triggered guidance SMT job related information) provides improved traceability and/or less error-prone kitting and replenishment processes.
An IR-based or RFID-based ESL system may be used for providing (e.g., dynamically/automatically changing) the SMT job related information from the SMT information database on the barcode scanner display 3020.
When preparing for upcoming SMT pick-and-place jobs, the SMT operator handling the barcode scanner 3000 with the display 3020 may also have an input possibility on (or associated with) a barcode or an external display unit, where the input mechanism may be the scanning of a barcode (e.g., a conventional barcode on a container or on, or associated with, an ESL display itself) by the scanner input device 3040, and where the barcode scanning action of the operator may be sending data (e.g., through IR or RFID data) to a controller unit associated with the barcode or an external display unit. The controller unit may trigger sending direct uplink SMT job related information to a controlling system (e.g., a base station and related software, the SMT information database via an IR and/or RFID-based ESL system); saving SMT job related information to be available at the next scheduled communication event; or displaying content on the barcode scanner display to change (e.g., between given or, alternatively, desired or predefined messages).
The trigger 3060 may be used to activate the scanner input device 3040 to perform a scanning operation. The buttons 3080 may be used to modify/update information on the display 3020, and transmit the updated information to the ESL system to update the ESL database.
The barcode scanner display 3020 may be configured to change its appearance to more dearly indicate to the SMT job operator where to pick the next a container for an upcoming SMT pick-and-place job. In one example, the barcode scanner display 3020 may change its appearance in response to the scanning of a barcode by the operator or pushed down instructions from the SMT information database using or via a separate ESL system or the operator's pushing of a button. The barcode scanner display 3020 may automatically/dynamically change front dark to bright and/or change color to indicate to the operator in which order the container should be at least one of: loaded into a bin; fetched by the operator from storage shelves in a kitting or replenishment process; or stored in an automatic SMD component warehouse inducting a robot.
The ESLs discussed herein may be e-paper labels.
The barcode scanner display 3020 may show an operator what to do independently if the bin is in the machine or in the kitting area (e.g., during a replenishment process or kitting process). The barcode scanner display may also be used to directly show what the operator has on the shelves, and sequentially guide the operator in collecting the containers.
One or more example embodiments may enhance the material handling process to reduce the effort of bringing and tracking components during kitting and replenishment processes (e.g., improved traceability and more efficient and less error prone SMT job related actions performed by the operator).
In more detail,
Using electronic tags or labels comprising electronic barcodes to track bins, trolleys, containers, and the components carried by, contained in or associated with, the bins, trolleys, or containers, and display SMT job related information related to said bins, trolleys, containers, and associated components, the system of the technology disclosed reduces the risk of error and speeds up setup and changeover times. It keeps track of quantity, batch code, current location and floor life for each and every component.
At least some example embodiments may inform and give guidance to the operator by providing, for the operator to view, display data from the factory floor on displays or electronic labels during production, and integrate it with a factory-wide tracking system or export display data for further processing. The displays or electronic Libels may be associated with and/or may be attached to a carrier (e.g., a bin, a movable trolley or a container adapted for carrying at least one plastic bag with components), a shelf for storing components or a table for performing replenishment work or kitting work.
The display or electronic label is provided with an electronic barcode that can be scanned by the operator using a barcode reader in order to display information to the operator related to the preparation for an ongoing or upcoming pick-and-place job (e.g., replenishment work, kitting work or during loading of a container).
The displays or electronic Libels are provided with at least one electronic barcode that may be scanned by the operator using a barcode reader in order to automatically (e.g., via a software tool and/or network of the SMT system) initiate an update of SMT job information in the SMT information database, where the updated SMT job information can subsequently be retrieved by the pick-and-place machine, the SMD warehouse or other units of the SMT system, retrieved by the action (e.g., scanning of a barcode, such as an electronic barcode) or other request of the operator or automatically pushed down (e.g., using software creating, such as a bitmap image, provided to the control unit of a separate communications network and system, such as an ESL system discussed above that pushes down display data to the displays or electronic labels) to guide the operator in preparation of an ongoing or upcoming pick-and-place job (e.g., replenishment work, kitting work or during loading of a container or box).
The display or electronic label of the carrier, table or shelf is further associated with or provided with an input device dial can be activated or pushed by the operator in order to display information to the operator related to the preparation for an ongoing or upcoming pick-and-place job (e.g., replenishment work, kitting work or during loading of a container).
The display or electronic label of the carrier, table or shelf is provided with an input device that can be used, activated or pushed by the operator to provide input (e.g., event-based input) to the control unit of the display/electronic label in order for the control unit of the display/electronic label to provide display information to the operator related to the preparation for an ongoing or upcoming pick-and-place job (e.g., replenishment work, kitting work or during loading of a container).
The display or electronic label is provided with an input device that can be used, activated or pushed by the operator to provide input (e.g., event-based input) to the control unit of the display/electronic label in order for the control unit of the display/electronic label to automatically (e.g., via a software tool and/or network of the SMT system) initiate an update of SMT job information in the SMT information database, where the updated SMT job information can subsequently be automatically retrieved by the pick-and-place machine, the SMD warehouse or other units of the SMT system, retrieved by a request of the operator or automatically pushed down (e.g., via a software tool and control unit creating image data, e.g., bitmap image data, that is sent to the a separate communications network and system, e.g., ESL system that pushes down display data to the displays/electronic labels) to guide the operator in preparation of an ongoing or upcoming pick-and-place job (e.g., replenishment work, kitting work or dining loading of a container).
As mentioned above, a container according to one or more example embodiments may be configured to have the same or substantially the same geometry and/or dimensions as a “normal” tray and/or component tape reel, such that the container may be fetched by the actuator/robot.
The container (or the separate storage compartments of the container) may be associated with an identifier or tag (e.g., a barcode and/or radio-frequency identifier (RFID) tag), which in turn may be associated with SMT job related information, location information or other intelligence that may be provided to (and/or known by) a database that updates SMT job related information (related to a pick and place job) in a SMT system and/or that is provided to (and/or known by) a separate e label system. By providing a container with an external geometry of a standard SMD component reel (or a geometry that is similar or substantially similar to tire geometry of a component tape reel or a reel+tape guide packet), components delivered in containers other than component tape reels (e.g., plastic bags with components) may be handled and stored in an automatic handling unit such as an automatic SMD warehouse. According to at least some example embodiments, the new containers may be compatible with current SMD warehouses and automated storage solutions. In addition, objects related to SMD processes (e.g., special tools, fixtures, odd shaped components, PCBs, board supports, etc.) may be handled and stored in an automated storage solution, such as an SMD warehouse.
Each container may be provided with one or more storage compartments. Each of the storage compartments may be configured to store one or more plastic bags containing electronic components, so that a plurality of bags with mutually different component types may be stored separately in the same container. The container may also be provided with, or associated with, an electronic label (e-label, such as an electronic shop/shelf label (ESL) as discussed above with regard to
Example embodiments may enable improved material handling solutions relative to the conventional art by providing an automatic solution for handling bags (e.g., plastic bags) including components (e.g., components that are not stored on component tape reels) as well as other objects related to SMD processes and/or pick-and-place jobs/machines, such as special tools, fixtures, odd shaped components, PCBs, board supports, etc.
Example embodiments also provide the ability to handle other objects more easily than component reels related to SMD process in an automatic storage handling unit (e.g., an automatic SMD warehouse). By providing an intelligent box that may be handled in an automatic manner (e.g., an automatic SMD warehouse including an actuator, such as a robot, for handling the containers/boxes), a relatively large variety of components and objects needed in electronic production may be handled. In one or more example embodiments, providing an e-label on, or associated with, the box may enable provisioning of dynamic information to an operator or related machines when handling the container. A display may be attached to, or associated with, the container. The display may display dynamic information based on the current state of the container display information related to the next action for the operator. One or more example embodiments may enable easier handling, for example, components in bags or cut pieces of component tape. One or more example embodiments may also provide the ability to store, and automatically provide, other objects related to production (e.g., fixtures, special tools, the PCBs themselves, tube component adapters, etc.).
The container may be configured to carry, for example, plastic bags with components. In at least one example embodiment, the container may act as a conventional tray box, rather than a 4″, 7″, 13″ or 15″ tape reel. In at least this example embodiment, the automated SMD warehouse may handle the container as a tray box.
According to at least one example embodiment, the e-label may be affixed to the sidewalls, base or a portion of the container, other than the lid.
According to at least some example embodiments, all or substantially all of the space that is not seen by the sensors in the automated SMD warehouse may be used.
If the cover is about 8 millimeters (mm) thick, then a container that has a height of about 32 mm with a cover, is only about 24 mm without the cover. Thus, in this example, the container without the cover fits in a 24 mm storage position. Moreover, if the container lid is only about 8 mm thick, then a container that has a height of about 24 mm with a cover and only about 16 mm without a lid. Thus, the container without the cover fits in a 16 mm storage position. Moreover, the vertical height of the container itself may be decreased if a cover is not needed. The display of an e-label may be arranged at an angle such that the display is visible by a user from above and from the side.
The display may be mounted vertically or horizontally on or in a given container.
The container may be configured to be stacked with other containers with or without a lid, and such that the display is visible to a user while the containers are stacked.
According to at least some example embodiments, the e-label may be arranged at the rear of the container, which may reduce the risk of the container tilting forward if heavy objects are placed on the opposite side of the container. Counter weights may be placed under or on the side of the e-label to balance the container.

As shown in
According to one or more example embodiments, an e-label may be attached to a top cover or any other portion of a container. In at least one example embodiment, the top cover may be removable. In one example, the e-label may be scanned when loading and/or unloading the container.
According to one or more example embodiments, an e-label may have a display portion with a diagonal of about 2.6″, and the e-label may be arranged at an angle of about 60 degrees relative to the base of the container, such that the e-label fits within a container resembling a 24 mm tape (e.g., a total 30.4 mm high).
According to at least some example embodiments, tire e-label 4002 may be readable both from the front and for the barcode reader in the automated SMD warehouse (e.g., including an actuator/robot).
According to at least some example embodiments, containers or tray boxes may be shaped and configured as conventional component tape reels. In at least some example embodiments, the containers or tray boxes may have diameters of 7″ or 13″, may have depths between about 8 mm and about 56 mm, inclusive, and may use all or substantially all (e.g., about 100%) of the available volume for storage.
According to at least some example embodiments, the containers may be compatible with devices for handling component tape reels, including conventional SMD towers or warehouses.
One or more example embodiments also provide a container configured to function as a tray box. According to at least some example embodiments, the container may occupy a 13″ position, and may support multiple carriers.
One or more example embodiments may provide a “super-sized” tray box, an example of which is shown in
In one example, the e-label may br placed on the outside to increase storage space within the container.
By tilting the e-label, a JEDEC tray may fit in the container.
A static label may also be placed on the cover tray box, for example, when the e-label is arranged off center.
If the tray box cover is about 8 mm thick, then the tray box may be inserted/stored without the cover and use less space in a SMD tower. Moreover, time required to access the content of the tray box may be decreased. Additionally, the container or tray box may include a recessed portion at the rear, wherein the recessed portion may be configured such that a gripper arm may grab and lift the container or tray box similar to a conventional tray.
In more detail,
The holder may enable the container or tray box to be used as a storage for smaller items on a normal shelf (e.g., outside the tower or with newer towers) stacking them on each other in a pile. The support structures may be fixed to containers and/or tray boxes discussed herein.
According to at least some other example embodiments, e-labels may be placed in 45 degrees, and be visible from both the top and the side of the containers or tray boxes.
At least some example embodiments provide a tray box (or container) with an external geometry of a standard SMD component reel. Boxes with this external geometry enable storing of components delivered in containers other than standard SMD component reels (e.g., bags with components) in a SMD tower (e.g., a conventional SMD tower) with little or no modification to the SMD tower itself. Boxes with such external geometry also enable automatic storing and handling of other objects related to SMD processes, such as special tools, fixtures, odd shaped components, PCBs, board supports, etc. As discussed herein, the tray boxes may also be referred to as boxes or containers.
As discussed herein, boxes according to at least some example embodiments may include e-labels for displaying various information in the different phases of the container and/or usage of the container. The e-labels may be permanently, temporarily, or removably fixed to the container or a cover of the container.
Conventional SMD towers with STSys 1.3 can support containers or tray boxes of three sizes: Tray Box 16. Tray Box 32 and Tray Box 44. A box is detected by a SMD tower with a line of 3 diameter sensors in the front of the terminal “floor”. In one example, if the 3 diameter sensors detect a straight line, then the SMD tower determines that the container is a tray box. If the two outermost sensors detect an object just prior to the middle sensor when the object is moved into the SMD tower, then the SMD tower determines that the box is a conventional SMD component reel (e.g., a round object).
According to at least some example embodiments, firmware of a SMD tower tray be adapted to accept a straight line further from the center titan a distance associated with conventional tray boxes.
A SMD tower may also measure the height of a container moved into the SMD tower. In one example, the height of a container is measured by sensors on the side of the “walls” of a SMD tower. Conventional tray boxes, such as Tray Box 16, Tray Box 32 and Tray Box 44 have actual heights of about 26 mm, 42 mm and 60 mm, respectively.
In order for first generation containers to be compatible with conventional SMD towers with STSys, only the three existing size containers or tray boxes (e.g., Tray Box 16, Tray Box 32 and Tray Box 44) adapted for 13″ magazines may be used in a SMD tower. Since there are a relatively limited number of 44 mm high 13″ space magazines in standard SMD towers with standard configuration, a compromise for storage capability may be achieved by using the 32 mm high 13″ magazines. A 16 mm high 13″ magazine may also be used, but provides less storage space.
Example embodiments may be adapted to show (e.g., using an e-label or other display) content, including what to provide and/or collect from a container. Example embodiments may also utilize provide/idle states for the containers.
SMD tower firmware, according to at least some example embodiments, may be adapted for larger containers or tray boxes, and may have improved support for multiple objects in containers or tray boxes.
According to at least some example embodiments, geometry of the current containers or tray boxes may be used as a guide. Containers or tray boxes, according to at least some example embodiments, may be as large (e.g., have diameters of 13″) and as high (e.g., for 32 mm Tray Box 32 the height limit is about 42 mm) as possible.
Referring to
The container 6200 also includes a hole pattern 6410 at the base (or bottom) of the container (e.g., between the orientation pins 6406). The hole pattern 6410 may be used to align the container by centering a pin in the bottom of the container.
Containers according to at least some example embodiments may be utilized without a cover. Each sensor may have the same visible height and/or the containers may have a groove at the rear of the container configured to receive a gripper arm (e.g., of an actuator in a SMD Tower) to move the container.
Containers according to at least some example embodiments may be separated into sections using, for example, inserts. Inserts may be customized (e.g., ESD foam with the same or substantially the same geometry as the container where the user may cut out portions as desired).
Still referring to
An e-label 6202 may be mounted on the container 6200 itself (rather than on the cover). The e-label 6202 may be visible and readable to a barcode reader (not shown) of the SMD Tower and/or visible and readable from the front portion of the container. The e-label 6202 may be removable, interchangeable, and may have a replaceable battery. The e-label 6202 may be fixed to the container 6200 at an angle. The e-label 6202 may be any suitable e-label, including e-labels according to example embodiments discussed herein.
According to at least some example embodiments, the container 6200 may be configured to hold e-labels of various sizes including, for example, e-labels of about 2.0″, about 2.2″ and/or about 2.6″.
Containers according to at least some example embodiments may have a block with a static barcode. The entire e label front may be a module on the container, and another module may serve as the static barcode.
As mentioned above, the container 6200 may further include a cover 6204. The cover 6204 may be relatively easily removable. The cover 6204 may have holes 6208. A portion of the holes 6208 may include one or more 13 mm holes configured to receive a gripper arm (e.g., of an actuator of a SMD Tower) on the top cover 6204. Others of the holes 6208 may be other gripping holes in the cover 6204. Still others of the holes 6208 may be configured to receive the orientation pins 6406 at the base of other containers when stacked vertically as shown, for example, in
Walls of the container 6200 may have gripping points, and the inside and/or the outside of the base of the container 6200 may be composed of friction material to reduce movement of the box and/or objects within the container (e.g., when an actuator of the SMD Tower is moving). In at least one example embodiment, the container 6200 may be made of an ESD safe material.
