After the test is complete, the FPC is removed and placed at the unloading station, where it is then re-transferred to the loading station, allowing for the recycling of multiple FPCs.
[0004] However, during the FPC recycling process, technicians need to manually collect the multiple FPCs that have been pulled out at the unloading station and manually transfer them to the loading station, resulting in reduced testing efficiency. Utility Model Content

[0011] Optionally, both the loading station and the unloading station have a buffer table and a material table, and the buffer table is located between the material table and the conveyor line, and the buffer table and the material table are both used to place the silo.

[0017] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.
[0018] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:
[0019] In the FPC transfer device provided by the present invention, at the loading station, a splicing robot sequentially removes the FPCs from the loading hopper at the loading station and then splices them with the display module for a crimp test.

[0034] Example:
[0035] Figure 1 This is a structural diagram of an FPC transfer device provided by an embodiment of the utility model. Figure 2 yes Figure 1 A partial enlarged view, combined with Figure 1 and Figure 2 As shown, the transfer device includes a conveying line 1, multiple silos 2, and a transfer component.
[0036] The conveyor line 1 extends along the first direction (X-axis direction), and the two ends of the conveyor line 1 are respectively provided with a loading station 11 and an unloading station 12 for placing the silo 2. The conveyor line 1 is used to transport the silo 2 back and forth (the conveyor line 1 can transport the silo 2 to the left or to the right), and each silo 2 is used to stack and position multiple FPCs in sequence. The transfer component includes a loading hand 3 and an unloading hand 4. The loading hand 3 is used to transfer the silo 2 between the loading station 11 and the conveyor line 1 (that is, the loading hand 3 can transfer the full silo 2 from the conveyor line 1 to the loading station 11, and can also transport the empty silo 2 from the loading station 11 to the conveyor line 1), and the unloading hand 4 is used to transfer the silo 2 between the unloading station 12 and the conveyor line 1 (that is, the unloading hand 4 can transfer the empty silo 2 from the conveyor line 1 to the unloading station 12, and can also transport the full silo 2 from the unloading station 12 to the conveyor line 1).
[0037] In the FPC transfer device provided by the present invention, at loading station 11, a splicing robot sequentially removes the FPCs from hopper 2 at loading station 11 and then splices them with the display module for a crimp test. Once all the FPCs in hopper 2 are removed, loading arm 3 transfers the empty hopper 2 to conveyor line 1, which transports the empty hopper 2 from left to right to the other end of conveyor line 1. Unloading arm 4 then transfers the empty hopper 2 from conveyor line 1 to unloading station 12.
[0038] As for the unloading station 12, the wire pulling robot unplugs the FPC from the above-mentioned products (display module and FPC) that have completed the crimping test and places them in the empty silo 2 in sequence. When the FPC in the silo 2 is full, the unloading arm 4 transfers the full silo 2 to the conveyor line 1. At this time, the conveyor line 1 transports the full silo 2 from right to left to one end of the conveyor line 1, and the loading arm 3 can transport the full silo 2 to the loading station 11. In this way, not only can the FPC be taken out in sequence at the loading station 11 through the silo 2 and neatly stacked at the unloading station 12, but the silo 2 can also be automatically circulated and transported, which automatically realizes the recycling of FPC, avoids manual collection, sorting and transportation, and improves testing efficiency.
[0039] That is to say, the FPC transfer device provided by the present invention can not only realize the sequential retrieval of FPCs at the loading station 11 through the hopper 2 and the neat stacking of FPCs at the unloading station 12, but also automatically realize the recycling of FPCs, avoid manual collection, sorting and transfer, and improve test efficiency.
[0040] For example, a detection device is provided between the loading station 11 and the unloading station 12. The plug-in robot grabs the FPC in the loading bin 2 of the loading station 11 and plugs it into the display module, and transfers it to the detection device for detection. After the detection is completed, the wire-pulling robot unplugs the FPC and transfers the FPC to the loading bin 2 of the unloading station 12, thereby shortening the FPC transfer distance.
[0041] Exemplarily, the silo 2 includes a bottom plate and a plurality of side plates, which are arranged to form a U-shaped structure, so that a plurality of FPCs can be stacked and positioned.
[0042] It should be noted that the two ends of the conveyor line 1 can correspond to 2 or 3 loading stations 11 and unloading stations 12, so as to improve the plugging and unplugging efficiency of the FPC, and the present utility model does not impose any restrictions on this.
[0043] Figure 3 This is a schematic diagram of the structure of the loading hand provided by the embodiment of the utility model. Figure 3 As shown, the loading arm 3 includes a first linear module 31 and an electric clamp 32. The first linear module 31 extends along the second direction (Y-axis direction). The output end of the first linear module 31 is transmission-connected to the electric clamp 32. The electric clamp 32 is used to clamp the hopper 2.
[0044] In the above embodiment, the first linear module 31 can be brought to the electric clamp 32 to realize the transfer between the conveyor line 1 and the loading station 11, thereby realizing the transfer of the silo 2.
[0045] Furthermore, the loading arm 3 includes a second linear module 33, which extends along the third direction (Z-axis direction). The output end of the first linear module 31 is transmission connected to the second linear module 33, and the output end of the second linear module 33 is transmission connected to the electric clamp 32.
[0046] It is easy to understand that the second linear module 33 can realize the lifting and lowering of the electric clamp 32, so as to prevent the first linear module 31 from interfering with other structures or other silos 2 when the silo 2 is moved horizontally.
[0047] For example, the second linear module 33 corresponds to two electric grippers 32 , and each electric gripper 32 can be used to transfer the silo 2 on each loading station 11 .
[0048] For example, the loading arm 3 includes a plurality of columns 34 arranged at intervals and extending along the third direction. The first linear module 31 is located on the plurality of columns 34. The columns 34 support and elevate the first linear module 31, allowing the electric gripper 32 to be higher than the loading station 11, thereby facilitating gripping the hopper 2.
[0049] It should be noted that the structure of the unloading arm 4 is the same as that of the loading arm 3 , that is, the unloading arm 4 also includes a first linear module 31 , an electric clamp 32 , a second linear module 33 and a column 34 .
[0050] Figure 4 This is a partial enlarged view of the loading station provided by the embodiment of the utility model, as shown Figure 4 As shown, the loading station 11 has a buffer table 111 and a material table 112 , and the buffer table 111 is located between the material table 112 and the conveyor line 1 , and both the buffer table 111 and the material table 112 are used to place the silo 2 .
[0051] In the above embodiment, the material table 112 serves to place a full silo 2 or a silo 2 that is unloading material, while the cache table 111 serves to buffer the silo 2 , temporarily placing the silo 2 transported by the conveyor line 1 on the cache table 111 .
[0052] For example, the silo 2 on the material platform 112 serves to unload materials in sequence, and the full silo 2 transported by the conveyor line 1 is transported to the buffer table 111 under the control of the loader 3. The loader 3 can then transfer the empty silo 2 on the material platform 112 to the conveyor line 1 and then transport it away, and transport the full silo 2 on the buffer table 111 to the material platform 112.
[0053] Furthermore, the material table 112 has a first operating area 1121 and a second operating area 1122, and the loading station 11 and the unloading station 12 both have a rotating motor 113, the output shaft of the rotating motor 113 is located between the first operating area 1121 and the second operating area 1122, and the output end of the rotating motor 113 is transmission-connected to the material table 112 to switch the positions of the first operating area 1121 and the second operating area 1122.
[0054] In the above embodiment, by setting the first operating area 1121 and the second operating area 1122 on the material table 112, the two positions can be interchanged, so that the operating area corresponding to the plug-in robot always has the FPC material bin 2, ensuring that the plug-in robot can always take the material.
[0055] For example, when the first operating area 1121 is filled with silos 2 and the silos 2 in the second operating area 1122 are gradually unloading, the plug-in robot retrieves material from the second operating area 1122. When the silos 2 in the second operating area 1122 have finished unloading and become empty, the rotary motor 113 drives the material platform 112 to rotate 180°, so that the filled silo 2 in the first operating area 1121 is aligned with the plug-in robot. The plug-in robot can retrieve material without stopping, without having to wait for the loading arm 3 to deliver a full silo 2. The second operating area 1122 is now away from the plug-in robot, and the empty silo 2 can be unloaded.
[0056] Similarly, the unloading station 12 also has a buffer table 111 and a material table 112, and its structure is the same as that of the loading station 11, which will not be repeated here.
[0057] Figure 5 This is a partial enlarged view of the conveyor line provided by the embodiment of the utility model, such as Figure 5 As shown, the transfer device further includes two finger cylinders 5, and the two output ends of the two finger cylinders 5 are respectively facing the two ends of the conveying line 1 to clamp and straighten the silo 2.
[0058] In the above embodiment, when the silo 2 is transported to both ends of the conveyor line 1, the corresponding finger cylinder 5 can clamp the silo 2 so that the silo 2 is placed in a suitable position, which is convenient for the loading hand 3 or the unloading hand 4 to accurately grasp and transport it.
[0059] It should be noted that, in other embodiments of the present invention, the loading arm 3 or the unloading arm 4 may also be a robotic arm, and the present invention does not impose any limitation on this.
[0060] Furthermore, a proximity sensor 51 is provided on the cylinder body of the finger cylinder 5 . The proximity sensor 51 is used to sense the silo 2 . The proximity sensor 51 is electrically connected to the finger cylinder 5 , and the proximity sensor 51 is located between two output ends of the finger cylinder 5 .
[0061] That is to say, when the hopper 2 is transported to the position corresponding to the loading hand 3 or the unloading hand 4 on the conveyor line 1, the hopper 2 just triggers the proximity sensor 51, and the proximity sensor 51 transmits the sensing signal to the finger cylinder 5, and the finger cylinder 5 will automatically clamp and straighten the hopper 2 to achieve precise positioning of the hopper 2.
[0062] In this embodiment, the loading station 11 and the unloading station 12 both include a base 114 and a frame 115. The base 114 is located on the frame 115 and is used to place the silo 2. The frame 115 supports and elevates the base 114, while the base 114 can support the silo 2.
[0063] Illustratively, a foot cup is provided at the bottom of the frame 115 , and the base 114 can be leveled by the foot cup.
[0064] Exemplarily, the loading arm 3 and the unloading arm 4 can be respectively arranged on corresponding bases 114 .
[0065] An embodiment of the present invention further provides a testing device, which includes the FPC transfer device as described above.
[0066] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
