Description

Technical Field

[0001] This invention relates to the field of IC testing technology, and in particular to a device for preventing incorrect allocation. Background Technology

[0002] When the required number of trays for IC product testing is reached, trays containing a certain number of IC products need to be secured with Velcro of different colors. However, there is currently no dedicated binding platform for the binding operation, and the Velcro is removed manually without any error prevention or control.

[0003] Specifically, the machine lacks a designated area for binding operations; all binding of Velcro is done in the material cabinet. Currently, the material cabinet is a flat design with no designated space for Velcro, requiring the tray to be lifted during binding, which easily leads to accidents such as tray breakage, IC loss, and IC damage. Furthermore, the existing Velcro is placed directly on the side of the material cabinet, requiring manual removal during operations. However, the material cabinet currently lacks a foolproof design, making it easy to remove the wrong Velcro, resulting in IC mixing risks. These shortcomings severely impact IC production efficiency and easily cause economic and reputational losses to the company due to accidents such as tray breakage, IC loss, IC damage, and IC mixing. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-mistake distribution device. By adding a binding table with binding slots to the workbench, it avoids the risk of tray explosion, IC loss, and IC damage caused by binding trays loaded with IC products. In addition, it can selectively close the corresponding first openings through a first door panel. By selectively closing different first storage cavities, it avoids the risk of IC mixing caused by human error in taking the wrong binding Velcro. Furthermore, the opening control signal of its first door panel is suitable for association control with the handler tray signal, the company's ERP customer test information, etc., which facilitates linkage with the above-mentioned external equipment and effectively improves adaptability and production efficiency.

[0005] To achieve the above objectives, the present invention discloses an anti-misplacement distribution device, which includes a workbench and a binding mechanism. The binding mechanism includes a binding platform, a first housing, a first partition, and a first door panel. The binding platform is disposed on the workbench and is used to support a tray. The binding platform has binding grooves that match the contour of the binding hook and loop fasteners. The first housing has a hollow structure to form a first storage cavity. A plurality of first partitions are installed at intervals in the first storage cavity to divide the first storage cavity into a plurality of first storage cavities. The first storage cavities are used to store the binding hook and loop fasteners. Each first storage cavity has a first opening, and each first opening corresponds to a first door panel. The first door panel can selectively close the corresponding first opening.

[0006] Compared with the prior art, the binding table of the present invention is set on the workbench and is used to carry the tray. The binding table has binding grooves that match the outline of the binding hook and loop fasteners. The first box has a hollow structure to form a first storage cavity. Multiple first partitions are installed at intervals in the first storage cavity to divide the first storage cavity into multiple first storage cavities. The first storage cavities are used to store binding hook and loop fasteners. Each first storage cavity has a first opening, and each first opening corresponds to a first door panel. The first door panel can selectively close the corresponding first opening. On the one hand, by adding a binding table with binding grooves to the workbench, it avoids the risk of tray explosion, IC loss, and IC damage caused by binding trays loaded with IC products. On the other hand, by selectively closing the corresponding first openings with the first door panels, it avoids the risk of IC mixing caused by human error in taking the wrong binding hook and loop fasteners. Furthermore, the opening control signal of the first door panel is suitable for association control with the handler tray signal, the company's ERP customer test information, etc., which facilitates linkage with the above-mentioned external equipment and effectively improves adaptability and production efficiency.

[0007] Preferably, the binding mechanism further includes a hook disposed within the first storage cavity, the hook being used to hang the binding Velcro.

[0008] Preferably, the anti-mistake distribution device further includes a magnetic cylinder, the output end of which is connected to the first door panel, and the magnetic cylinder drives the first door panel to selectively close the first opening according to a first control signal.

[0010] The magnetic cylinder has an upward state, an initial state, and an abnormal state. When the magnetic cylinder is in the upward state, the first door panel is pushed open by the magnetic cylinder to open the first opening. When the magnetic cylinder is in the initial state, the first door panel closes the first opening. When the magnetic cylinder is in the abnormal state, the magnetic cylinder cannot act according to the first control signal.

[0011] The magnetic cylinder controls the LED indicator to light up different colors when it is in different states.

[0012] Preferably, the anti-mistake distribution device further includes a reset switch and a manual switch, which are electrically connected to all magnetic cylinders respectively.

[0021] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please see Figures 1-3As shown, the anti-misplacement distribution device 100 of this embodiment is adapted to receive trays equipped with IC products from the IC tester 200, and to distribute the binding hook and loop fasteners according to a first control signal output by the IC tester 200, which includes the IC product type and the number of IC products loaded on the tray. It is understood that the IC tester 200 has multiple dispensing areas. Each dispensing area uses a photoelectric sensor to count the number of IC products loaded on the corresponding tray. For example, when the number of trays loaded with IC products reaches ten, the photoelectric sensor switches from normally closed to normally open, and the IC tester 200 determines it as an integer tray binding; conversely, when the number of trays loaded with IC products is greater than two but less than ten, the photoelectric sensor remains normally open, and the IC tester 200 determines it as a repetitive tray binding. Integer tray binding and repetitive tray binding require different colored binding hook and loop fasteners for differentiation.

[0023] The anti-misplacement distribution device 100 includes a workbench 1 and a binding mechanism. The binding mechanism includes a binding table 2, a first housing 3, a first partition 4, and a first door panel 6. The binding table 2 is located on the workbench 1 and is used to support trays, such as multiple stacked trays. The binding table 2 has binding grooves 21 that match the contours of the binding hook and loop fasteners. The binding hook and loop fasteners are placed in the binding grooves 21 without protruding from the surface of the binding grooves 21. The trays to be bound can be directly bound without tilting or flipping the trays, thus avoiding tray breakage that could lead to the loss or damage of IC products. It also prevents the binding hook and loop fasteners from crushing the IC products on the trays.

[0024] The first housing 3 has a hollow structure forming a first storage cavity. Multiple first partitions 4 are spaced apart within the first storage cavity to divide it into multiple first storage compartments 31. Each first storage compartment 31 is used to store binding hook and loop fasteners. Each first storage compartment 31 has a first opening, and each first opening corresponds to a first door panel 6. The first door panel 6 can selectively close the corresponding first opening. It is understood that different first storage compartments 31 can hold binding hook and loop fasteners of different colors to facilitate differentiation between whole-number bundles, end-number bundles, IC product quantities, and IC product types, effectively reducing the risk of mixed materials.

[0025] Preferably, the binding mechanism further includes a hook 5, which is disposed in the first storage cavity 31 and is used to hang binding Velcro.

[0026] Preferably, the anti-mistake distribution device 100 further includes a magnetic cylinder 7, the output end of which is connected to the first door panel 6. The magnetic cylinder 7 drives the first door panel 6 to selectively close the first opening according to a first control signal. Specifically, the closure of the first opening by the first door panel 6 is achieved by lifting and retracting the output end of the magnetic cylinder 7.

[0027] Preferably, the anti-mistake distribution device 100 also includes LED indicator lights 8, each LED indicator light 8 corresponding to a first storage cavity 31. A magnetic cylinder 7 is electrically connected to the corresponding LED indicator light 8, and the LED indicator light 8 can illuminate multiple different colors. The magnetic cylinder 7 has an upward-push state, an initial state, and an abnormal state. When the magnetic cylinder 7 is in the upward-push state, the first door panel 6 is pushed open by the magnetic cylinder 7, opening the first opening. When the magnetic cylinder 7 is in the initial state, the first door panel 6 closes the first opening. When the magnetic cylinder 7 is in the abnormal state, the magnetic cylinder 7 cannot operate according to the first control signal. Different states of the magnetic cylinder 7 control the LED indicator lights 8 to illuminate different colors. Through the above settings, the operator can more intuitively understand the state of the corresponding magnetic cylinder 7 through the LED indicator lights 8, further preventing the mistaken use of the Velcro straps through manual observation.

[0028] Preferably, the anti-mistake distribution device 100 further includes a reset switch 9 and a manual switch 10. The reset switch 9 and the manual switch 10 are electrically connected to all magnetic cylinders 7 respectively. The reset switch 9 is used to reset all magnetic cylinders 7 from the abnormal state to the initial state. Specifically, when the state of any magnetic cylinder 7 is abnormal, the reset switch 9 can be pressed to cut off the electromagnetic sensor state of all magnetic cylinders 7, so that all magnetic cylinders 7 return to the top position.

[0029] The manual switch 10 is used to switch all magnetic cylinders 7 between the top position and the initial position. Specifically, the operator manually controls the state of all magnetic cylinders 7, which makes it convenient to manually remove the binding Velcro in special circumstances.

[0030] Preferably, the anti-mistake dispensing device 100 further includes a processing unit 11, which is communicatively connected to all the magnetic cylinders 7. The processing unit 11 is used to receive multiple first control signals from an external device (in this embodiment, an IC tester 200) and control the operation of the corresponding magnetic cylinder 7 according to the first control signals. Preferably, the processing unit 11 in this embodiment is a tablet computer, which is equipped with Velcro smart dispensing software. The parameter control of the anti-mistake dispensing device 100 and the IC tester 200 is performed through the Velcro smart dispensing software.

[0031] Preferably, the anti-mistake distribution device 100 further includes a proximity switch 12, which is electrically connected to the processing unit 11. Each first storage cavity 31 is provided with a proximity switch 12. When the binding hook and loop fastener is taken out from the first storage cavity 31, the proximity switch 12 sends a second control signal to the processing unit 11. The processing unit 11 counts the number of binding hook and loop fasteners taken out from the current first storage cavity 31 according to the second control signal.

[0032] Preferably, the anti-misdelivery distribution device 100 further includes a second housing 13 and a second partition 14. The second housing 13 has a hollow structure to form a second storage cavity. Multiple second partitions 14 are installed at intervals within the second storage cavity to divide the second storage cavity into multiple second storage compartments 131. These second storage compartments 131 are used to store bundled trays. The second storage compartments 131 can be numbered, and different second storage compartments 131 can store trays with different whole-number bundles, end-number bundles, IC product quantities, or IC product types.

[0033] Combination Figures 1-3 The binding table 2 of the present invention is disposed on the workbench 1. The binding table 2 is used to carry the tray. The binding table 2 is provided with binding grooves 21 that match the contour of the binding hook and loop fasteners. The first box 3 has a hollow structure to form a first storage cavity. Multiple first partitions 4 are installed at intervals in the first storage cavity to divide the first storage cavity into multiple first storage cavities 31. The first storage cavities 31 are used to store binding hook and loop fasteners. Each first storage cavity 31 has a first opening. Each first opening corresponds to a first door panel 6. The first door panel 6 can selectively close the corresponding first opening. On the one hand, by adding a binding table 2 with binding grooves 21 to the workbench 1, it avoids the risk of tray explosion, IC loss, and IC damage caused by binding trays loaded with IC products. On the other hand, by selectively closing the corresponding first openings through the first door panel 6, it avoids the risk of IC mixing caused by human error in taking the wrong binding hook and loop fasteners. Furthermore, the opening control signal of the first door panel 6 is suitable for use with the handler. The system links and controls tray signals, company ERP customer test information, etc., to facilitate linkage with the aforementioned external devices, effectively improving adaptability and production efficiency.
