[0031] Figure 1 Fig. 4 shows a schematic perspective view of a multi-station FPC test device 1 provided by an embodiment of the present utility model; Figure 2 Fig. 5 shows a schematic top view of a multi-station FPC test device 1 provided by an embodiment of the present utility model.

[0032] As Figure 1 and Figure 2 shown, the multi-station FPC test device 1 according to the present utility model includes a transport track 2 for transporting and carrying an FPC carrier plate 22 of an FPC product 21, at least two FPC test modules 3 provided on the side of the transport track 2, and a transfer robot 4 for transferring the FPC product 21 between the transport track 2 and the FPC test modules 3.

[0033] In the present utility model, the FPC test module 3 is preferably provided with two. That is, the FPC test module 3 includes a first FPC test module 3A and a second FPC test module 3B. The present utility model does not limit the number of the FPC test modules 3. Those skilled in the art can set three, four, five or six FPC test modules 3 according to actual needs, that is, set multiple test stations.

[0034] According to the multi-station FPC testing device 1 of the present utility model, multiple groups of FPC products 21 can be carried on the FPC carrier plate 22. Each group of FPC products 21 includes multiple FPC products 21, such as 8, 12, 16, 24, etc. FPC products 21. During the testing process, the FPC carrier plate 22 is transported to the working area of the handling robot 4 through the transportation track 2. The handling robot 4 first transports the first group of FPC products 21 to be tested from the FPC carrier plate 22 to the first FPC testing module 3A. During the gap when the first FPC testing module 3A tests the first group of FPC products 21, the handling robot 4 transports the second group of FPC products 21 to be tested from the FPC carrier plate 22 to the second FPC testing module 3B. Then, during the gap when the second FPC testing module 3B tests the second group of FPC products 21, the handling robot 4 transports the first group of FPC products 21 that have been tested back to the FPC carrier plate 22, and transports the third group of FPC products 21 to be tested from the FPC carrier plate 22 to the first FPC testing module 3A. Such cyclic operation is performed until all the FPC products 21 to be tested on the FPC carrier plate 22 are tested.

[0035] Figure 3A The three-dimensional structural schematic diagram of the pressing module 32 of the multi-station FPC testing device 1 provided by an embodiment of the present utility model is shown; Figure 3B The bottom structural schematic diagram of the pressing module 32 of the multi-station FPC testing device 1 provided by an embodiment of the present utility model is shown; Figure 4A The three-dimensional structural schematic diagram of the test carrier plate 31 and the upper pressing film block 33 of the multi-station FPC testing device 1 provided by an embodiment of the present utility model is shown; Figure 4B The three-dimensional structural schematic diagram of the upper pressing film block 33 of the multi-station FPC testing device 1 provided by an embodiment of the present utility model is shown.

[0036] As Figure 1 As shown in FIGS. 3 to 4, in the present utility model, each FPC testing module 3 preferably includes a test carrier plate 31 for placing the FPC product 21; a pressing module 32 that can move above the test carrier plate 31 for pressing the test carrier plate 31; and an upper pressing film block 33 provided below the test carrier plate 31 for upwardly pressing the test carrier plate 31.

[0037] For each FPC test module 3, after a group of FPC products 21 to be tested are transported to the test carrier plate 31, the pressing module 32 presses down on each FPC product 21 on the test carrier plate 31, and the upper pressing module 33 presses up the test needles (not shown) arranged inside the test carrier plate 31. Under the combined action of the pressing module 32 and the upper pressing module 33, the test needles arranged inside the test carrier plate 31 can be reliably electrically connected to the FPC product 21, and then the test needles transmit the information collected from the FPC product 21 to the test system, thereby determining and outputting the test results of the corresponding FPC product 21. In the present utility model, the test system for testing the FPC product 21 can adopt the existing test system, which will not be elaborated here.

[0038] As Figure 1 and Figure 2 shown, each FPC test module 3 further includes guide rails 34 arranged on both sides of the test carrier plate 31 and a driving unit 35 for driving the pressing module 32 to reciprocate on the guide rails 34. When the transfer robot 4 transports the FPC product 21, the driving unit 35 moves the pressing module 32 along the guide rails 34 to the rear of the test carrier plate 31 to ensure that the moving path of the transfer robot 4 is not interfered. After a group of FPC products 21 to be tested are transported to the test carrier plate 31, the driving unit 35 moves the pressing module 32 along the guide rails 34 to above the test carrier plate 31 to press the FPC product 21.

[0039] As Figure 3A shown, the pressing module 32 further includes a code scanning unit 321. The code scanning unit 321 can adopt a barcode scanner in the existing technology. The code scanning unit 321 is used to scan and collect data from the FPC product 21, thereby enabling electronic management of all FPC products 21 to be tested.

[0040] As Figure 3B shown, the pressing module 32 further includes a pressing bottom plate 322, a driving electric cylinder 324 for driving the pressing bottom plate 322 to move up and down, and a plurality of pressing components 323 arranged at the bottom of the pressing bottom plate. During the pressing process, the pressing components 323 press against the FPC product 21 to ensure reliable electrical connection between the FPC product 21 and the test needles. The number and arrangement of the pressing components 323 are not limited in the present embodiment and are determined by the number of FPC products 21 in each group to be tested and the type of the FPC product 21.

[0041] As Figure 4A and 4BAs shown in the figure, the upper top film block 33 includes multiple groups of independent upper top cylinders 331. Each group of independent upper top cylinders 331 is correspondingly arranged with a test pin, and is used to push the test pin to the position where it is electrically connected to the FPC product 21. Each group of independent upper top cylinders 331 acts independently without interference. Thus, flexible arrangement and combination of multiple groups of independent upper top cylinders 331 can be achieved to meet the test requirements of different FPC products 21.

[0042] Figure 5A The figure shows a schematic top view of the test carrier plate 31 of the multi-station FPC test device 1 provided by an embodiment of the present invention; Figure 5B The figure shows a schematic partial view of the test carrier plate 31 of the multi-station FPC test device 1 provided by an embodiment of the present invention.

[0043] As Figure 5A shown, the test carrier plate 31 includes multiple groups of FPC test units 311. The FPC test units 311 are used to carry the FPC products 21 to be tested. Each FPC test unit 311 includes one or more test pins, and the number of test pins is determined according to the test requirements of the FPC product 21 to be tested, and is not limited in the present invention.

[0044] As Figure 5A shown, in the present invention, the number of FPC test units 311 is preferably 12 groups. For short FPC products 21, each group of FPC test units 311 carries one FPC product 21 and completes the test of this FPC product 21.

[0045] For longer FPC products 21, every two groups of FPC test units 311 can be arranged relatively. As Figure 5B shown, on two relatively arranged groups of FPC test units 311, two FPC products 21 can be symmetrically carried. That is to say, one FPC product 21 is carried and tested by two groups of FPC test units 311. In the present invention, two relatively arranged groups of FPC test units 311 can carry and test two symmetrically placed FPC products 21 at the same time. Thus, through a compact layout, the test of as many FPC products 21 as possible can be completed.

[0046] Figure 6 The figure shows a three-dimensional structure schematic diagram of the transfer robot 4 of the multi-station FPC test device 1 provided by an embodiment of the present invention. As Figure 6As shown in the figure, the transfer robot 4 includes a robotic arm 41, a first suction cup unit 42, and a second suction cup unit 43 provided at the end of the robotic arm 41. Two suction cup units are provided at the end of the robotic arm 41. When the first suction cup unit 42 and the second suction cup unit 43 move above the test carrier plate 31, the completed FPC product 21 on the test carrier plate 31 can be removed by one of the suction cup units, and the FPC product 21 to be tested can be placed on the test carrier plate 31 by the other suction cup unit. Similarly, when the first suction cup unit 42 and the second suction cup unit 43 move above the FPC carrier plate 22, the FPC product 21 to be tested on the FPC carrier plate 22 can be taken away by one of the suction cup units, and the completed FPC product 21 can be put back on the FPC carrier plate 22 by the other suction cup unit. Thus, the transfer efficiency of the transfer robot 4 can be effectively improved.

[0047] As Figure 2 shown, in the present utility model, preferably, a plurality of fixing units 21 are provided above the conveying track 2. When the FPC carrier plate 22 is conveyed into the working range of the transfer robot 4, the fixing unit 21 fixes the FPC carrier plate 22. Thus, it can be ensured that the FPC carrier plate 22 is reliably fixed at a predetermined position during the operation of the transfer robot 4, which is beneficial for the transfer robot 4 to accurately complete the transfer work.

[0048] In summary, according to the multi-station FPC testing device 1 of the present utility model, the investment in testing equipment and manpower can be greatly reduced, the testing cost can be saved, and the testing efficiency can be improved.

[0049] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field under the spirit and technical idea disclosed by the present utility model of the punching hole detachment inspection type sample should still be covered by the claims of the present utility model.
