[0002] During the production of FPC (Flexible Printed Circuit), the resistance of the internal steel sheets needs to be measured. The relevant technologies usually use testing equipment with upper and lower molds, which requires manual loading and unloading, resulting in low efficiency and poor safety.

[0022] Please refer to Figures 1 to 3 and Figure 5 As shown, in one aspect, an embodiment of the present invention provides a steel sheet resistance testing device for an FPC, including a testing module 100, two loading / unloading modules 200, and a conveying module 300; the testing module 100 includes an upper mold module 110 and a lower mold module 120 that can be opened and closed, at least one of the upper mold module 110 and the lower mold module 120 is provided with a probe, which is adapted to be electrically connected to the steel sheet of the FPC; the loading / unloading module 200 is provided with a limiting groove, which is adapted to place the FPC and the release paper, and the FPC and the release paper are stacked in sequence; one of the two loading / unloading modules 200 One module is used for loading, and the other is used for unloading. The conveying module 300 is connected to the loading / unloading module 200 and the testing module 100. The conveying module 300 includes a conveying adsorption mechanism 310 and a conveying drive mechanism 320. The conveying drive mechanism 320 is adapted to drive the conveying adsorption mechanism 310 to move. The conveying adsorption mechanism 310 includes a first rotary drive member 311 and a plurality of suction cup mounting plates 312 arranged around the rotating shaft of the first rotary drive member 311. Each suction cup mounting plate 312 is connected to a plurality of vacuum suction cups 313. The vacuum suction cups 313 are adapted to adsorb FPC or release paper.

[0023] According to an embodiment of the present invention, the FPC sheet resistance testing device comprises stacked FPCs and release liner placed alternately in the limiting groove of the loading / unloading module 200 for loading. The conveying and adsorption mechanism 310, driven by the conveying drive mechanism 320, moves above the limiting groove, making the suction cup mounting plate 312 parallel to the FPC. The FPC is then picked up by the suction cup. After picking up, the first rotary drive member 311 drives the suction cup mounting plate 312 to rotate, making the next suction cup mounting plate 312 parallel to the release liner. The release liner is then picked up by the vacuum suction cup 313. After picking up, the conveying... The drive mechanism 320 drives the transport and adsorption mechanism 310, which carries the FPC and release paper, to move to the test module 100 side, loading the FPC onto the lower mold module 120. The test module 100 tests the FPC. During the test, the transport drive mechanism 320 can simultaneously drive the transport and adsorption mechanism 310 to transport the release paper to the loading and unloading module 200 for unloading. After the FPC test is completed, the transport and adsorption mechanism 310 moves to the lower mold module 120 to pick up the tested FPC and transport it to the loading and unloading module 200 for unloading. The above process is repeated to achieve automated testing.

[0024] It should be noted that in the existing technology, the testing equipment that uses suction cups to adsorb and transport FPCs for testing only has a single-sided adsorption structure. During the transportation process, the FPC and the release paper are adsorbed and transported separately. Since the structural dimensions of the FPC and the release paper are different, the adsorption requirements of the release paper may not be met when the adsorption conditions of the FPC are met, which leads to the problem of debugging difficulties. Moreover, the separate transportation results in low testing efficiency of the testing equipment, which affects the production efficiency of FPCs.

[0025] According to an embodiment of the present invention, the FPC sheet resistance testing device uses a transport and adsorption mechanism 310 to simultaneously adsorb and transport the FPC and the release paper, effectively avoiding the problem of scratches caused by the lack of release paper during the stacking of FPCs. Simultaneous transport can significantly improve testing efficiency. Furthermore, the vacuum suction cups 313 on different suction cup mounting plates 312 adsorb the FPC and the release paper respectively. The position and suction force of the vacuum suction cup 313 on a single suction cup mounting plate 312 are adaptively adjusted based on the structural dimensions of the FPC or the release paper. The device can stably adsorb both without frequent adjustment of the parameters of the vacuum suction cup 313, which significantly reduces the complexity of equipment debugging.

[0026] In some embodiments, combined with Figures 1 to 3 As shown, two loading and unloading modules 200 are respectively arranged on both sides of the test module 100 along the first direction; the conveying drive mechanism 320 includes an X-direction linear module 321, a Y-direction linear module 322 and a Z-direction lifting module 323. The X-direction linear module 321, the Y-direction linear module 322 and the Z-direction lifting module 323 are perpendicular to each other and the X-direction linear module 321 extends along the first direction (X direction in the figure). The X-direction linear module 321 and the Y-direction linear module 322 are suitable for driving the conveying and adsorption mechanism 310 to move horizontally, and the Z-direction lifting module 323 is suitable for driving the conveying and adsorption mechanism 310 to move up and down.

[0027] In this embodiment, two loading / unloading modules 200 are respectively arranged on both sides of the test module 100 along the first direction (X direction in the figure). The conveying drive mechanism 320 adopts a three-axis rectangular coordinate system composed of an X-axis linear module 321, a Y-axis linear module 322, and a Z-axis lifting module 323. During operation, the Z-axis lifting module 323 drives the conveying and adsorption mechanism 310 to lift and lower to pick up or release the FPC / release paper. The X-axis linear module 321 drives it to reciprocate between the loading / unloading module 200 for loading, the test module 100, and the loading / unloading module 200 for unloading along the first direction. The Y-axis linear module 322 drives it to extend and retract in the Y direction to ensure that the vacuum suction cup 313 corresponds to the position of the FPC or release paper. Through the three-axis linkage, the conveying and adsorption mechanism 310 is accurately positioned in three-dimensional space, thereby transferring the FPC and release paper sequentially between each station to complete the testing process.

[0028] In this embodiment, the X-axis linear module 321, the Y-axis linear module 322, and the Z-axis lifting module 323 can be slide modules, lead screw modules, cylinders, etc.

[0029] In other embodiments, the transport drive mechanism 320 may also be a robotic arm.

[0030] In some embodiments, combined with Figure 5 As shown, the lower mold module 120 includes a lower mold moving module 121 and a lower mold assembly 122. The lower mold moving module 121 extends perpendicularly to the first direction and is provided with a test loading / unloading station and a test station. The test station is located below the upper mold module 110 and is located below the moving path of the conveying and adsorption mechanism 310. The lower mold assembly 122 is connected to the movable end of the lower mold moving module 121.

[0031] In this embodiment, the lower mold moving module 121 drives the lower mold assembly 122 to reciprocate between the test loading / unloading station and the test station. When the conveying and adsorption mechanism 310 moves the FPC above the test loading / unloading station, the lower mold assembly 122 receives the FPC and completes the loading; then the lower mold moving module 121 drives the lower mold assembly 122 to move to the test station, at which time the upper mold module 110 moves down and closes with the lower mold assembly 122, and the probe contacts the steel sheet to measure the resistance; after the test is completed, the lower mold assembly 122 returns to the test loading / unloading station, and the conveying and adsorption mechanism 310 takes away the tested FPC.

[0032] In this embodiment, the movement of the lower mold assembly 122 allows the transport and adsorption mechanism 310 to complete the FPC handover without entering directly below the upper mold module 110, avoiding interference between the mold closing action and the transport path and improving the safety of equipment operation. At the same time, while the lower mold assembly 122 is undergoing pressing tests at the test station, the transport and adsorption mechanism 310 can perform the next loading and unloading action in parallel, effectively shortening the equipment waiting time and further improving testing efficiency. In addition, the layout of the lower mold moving module 121 perpendicular to the main transport movement direction (first direction) makes the overall structure of the equipment compact, the movement path planning simpler, and facilitates high-precision positioning.

[0033] In some embodiments, combined with Figure 1 As shown, the FPC steel sheet resistance testing equipment also includes an upper camera module 400, which is positioned above the loading / unloading module 200 for loading and is suitable for capturing positional images of the FPC and the release paper; the conveying drive mechanism 320 also includes a second rotary drive component 324, the extension direction of the rotating shaft of the second rotary drive component 324 is the same as the extension direction of the Z-axis lifting module 323, and the second rotary drive component 324 is suitable for driving the conveying adsorption mechanism 310 to rotate; the conveying drive mechanism 320 is communicatively connected to the upper camera module 400.

[0034] In this embodiment, the upper camera module 400 is positioned above the feeding module to pre-capture images of the actual positions of the FPC and release paper within the limiting groove. The second rotary drive component 324 in the conveying drive mechanism 320 is coaxially arranged with the Z-axis lifting module 323, which can drive the conveying and adsorption mechanism 310 to rotate in the horizontal plane. The testing equipment obtains the angular deviation between the FPC or release paper and the vacuum nozzle based on the position image data from the upper camera module 400. The second rotary drive component 324, in conjunction with the X-axis linear module 321 and the Y-axis linear module 322, adjusts the posture of the conveying and adsorption mechanism 310 in real time, so that the angle between the suction cup mounting plate 312 and the vacuum nozzle and the material to be picked up is precisely matched, and then the adsorption and conveying action is performed.

[0035] In this embodiment, the visual positioning and angle compensation functions effectively solve the problem that the vacuum suction cup 313 is difficult to accurately fit when the FPC is placed in an inconsistent position or has an angle deviation, thereby reducing the positioning accuracy requirements for the initially placed FPC.

[0036] In this embodiment, the second rotary drive 324 can be a stepper motor, a servo motor, or the like.

[0037] In this embodiment, the upper camera module 400 may include a camera and a fill light.

[0038] In some embodiments, combined with Figure 1 As shown, the FPC sheet resistance testing equipment also includes a lower camera module 500, which is set between the testing module 100 and the loading / unloading module 200 for loading. It is suitable for capturing positional images of the FPC adsorbed by the vacuum suction cup 313. The lower camera module 500 is communicatively connected to the conveying drive mechanism 320.

[0039] In this embodiment, during the process of transporting and adsorption mechanism 310 from loading / unloading module 200 to test module 100, it needs to stop on lower camera module 500 and have position images captured by lower camera module 500. The test equipment obtains the position deviation between the position of the adsorbed FPC and the position on the lower mold module 120 of test module 100 based on the position images, and controls the X-direction linear module 321, Y-direction linear module 322 and the second rotary drive component 324 of transport drive mechanism 320 to perform position compensation. Through visual positioning and angle compensation functions, the problem of FPC offset and difficulty in accurately placing it on lower mold module 120 caused by vacuum suction cup 313 adsorption process is effectively solved.

[0040] In this embodiment, the lower camera module 500 may include a camera and a fill light.

[0041] In some embodiments, combined with Figure 4As shown, the loading and unloading module 200 includes a loading mechanism 210 and a loading and unloading moving mechanism 220. The loading mechanism 210 is adapted to move under the drive of the loading and unloading moving mechanism 220. The extension direction of the loading and unloading moving mechanism 220 is perpendicular to the first direction. The loading and unloading moving mechanism 220 is provided with a first loading and unloading station and a second loading and unloading station. The first loading and unloading station is located at the end away from the conveying module 300, and the second loading and unloading station is located at the end close to the conveying module 300.

[0042] In this embodiment, the loading / unloading module 200 for loading materials drives the loading mechanism 210 to reciprocate between a first loading / unloading station and a second loading / unloading station perpendicular to the first direction (Y direction in the figure) via the loading / unloading moving mechanism 220. An operator places the stacked FPC and release paper onto the loading mechanism 210 at the first loading / unloading station, away from the transport module 300. The loading / unloading moving mechanism 220 then moves the loading mechanism 210 to the second loading / unloading station, closer to the transport module 300, where the transport and adsorption mechanism 310 picks up the material. The unloading / unloading module 200 for unloading materials operates similarly and will not be described further.

[0043] In this embodiment, by setting up a first loading / unloading station and a second loading / unloading station, the loading / unloading operation is physically separated from the material picking, thus achieving human-machine safety isolation. Operators can still prepare materials at the first loading / unloading station during equipment operation without stopping the machine to wait, which significantly improves testing efficiency.

[0044] In some embodiments, combined with Figure 4 As shown, the material loading mechanism 210 includes a base 211, a lifting drive 212, a material loading plate 213, and multiple limiting rods 214. The lifting drive 212 is connected to the base 211 and is adapted to lift the material loading plate 213. The material loading plate 213 is provided with a through groove 2131 extending from the outside to the inside. The first end of the limiting rod 214 passes through the through groove 2131, and the second end of the limiting rod 214 is slidably connected to the base 211. Corresponding to the four sides of the release paper, at least one limiting rod 214 is provided on each side for limiting.

[0045] In this embodiment, the material loading mechanism 210 positions the stacked release paper around its perimeter using multiple limiting rods 214 on the base 211. The first end of each limiting rod 214 passes through the through slot 2131 of the material loading plate 213 and then limits the edge of the material. The second end is slidably connected to the base 211 so that the position can be adjusted according to the size of the release paper. The lifting drive 212 is connected to the base 211 and lifts the material loading plate 213. As the conveying and adsorption mechanism 310 removes the material layer by layer, the lifting drive 212 gradually lifts the material loading plate 213 so that the uppermost material is always kept at a fixed picking height.

[0046] In this embodiment, the lifting drive component 212 is a rod lifting motor, but it can also be a cylinder, a lead screw module, a slide module, etc.

[0047] In this embodiment, the sliding connection of the limiting rod 214 can be in the form of a slide module, worm gear, lead screw module, etc.

[0048] In some embodiments, combined with Figure 3 As shown, the suction cup mounting plate 312 is provided with multiple rows of positioning hole groups 3121, and the positioning holes of two adjacent rows of positioning hole groups 3121 are arranged in a triangular shape.

[0049] In this embodiment, by setting up multiple rows of positioning hole groups 3121 with adjacent rows arranged in a staggered triangular pattern, the installation density and position adjustability of the vacuum suction cup 313 are significantly increased. This allows operators to flexibly select the most suitable adsorption point based on the different dimensions, bending areas, and weight distribution of the FPC or release paper, thus avoiding damage caused by the vacuum suction cup 313 falling on sensitive areas such as circuits, components, or openings.

[0050] The vacuum suction cup 313 can be fixed to the positioning hole by means of connectors (such as screws or bolts), or it can be magnetically attached to the suction cup mounting plate 312.

[0051] In some embodiments, combined with Figure 3 As shown, the vacuum suction cup 313 includes a suction cup assembly and a magnetic suction assembly. The magnetic suction assembly is connected to the end of the suction cup assembly facing away from the FPC, and the suction cup assembly is attached to the suction cup mounting plate 312 by the magnetic suction assembly.

[0052] In this embodiment, a detachable adsorption connection is achieved through the magnetic suction component and the suction cup mounting plate 312. On the one hand, the installation and position adjustment of the vacuum suction cup 313 can be completed quickly without the aid of tools. On the other hand, the operator can flexibly move the position of the vacuum suction cup 313 within the range of the triangular positioning hole group 3121 according to the size, shape and adsorption point requirements of the FPC or release paper, which significantly shortens the changeover and debugging time.

[0053] In some embodiments, combined with Figure 3 As shown, the conveying and adsorption mechanism 310 includes three suction cup mounting plates 312. Each suction cup mounting plate 312 includes a mounting plate portion 3122 and a connecting plate portion 3123. The connecting plate portion 3123 is connected to one side of the mounting plate portion 3122 and the two are arranged at an angle. The three suction cup mounting plates 312 are arranged sequentially around the rotating shaft of the first rotating drive member 311, and the connecting plate portion 3123 of the first suction cup mounting plate 312 overlaps and is fixed to the mounting plate portion 3122 of the subsequent suction cup mounting plate 312.

[0054] In this embodiment, the conveying and adsorption mechanism 310 is provided with three suction cup mounting plates 312 connected at an angle around the rotating shaft of the first rotating drive member 311, which are respectively defined as the first suction cup mounting plate, the second suction cup mounting plate, and the third suction cup mounting plate. The vacuum suction cup 313 of the first suction cup mounting plate is used to pick up the FPC to be tested from the loading and unloading module 200 for loading; the vacuum suction cup 313 of the second suction cup mounting plate is used to pick up the release paper; and the vacuum suction cup 313 of the third suction cup mounting plate is used to receive and convey the tested FPC from the testing module 100. During operation, the first rotary drive 311 drives the three suction cup mounting plates 312 to rotate synchronously, so that the first suction cup mounting plate is aligned with the loading and unloading module 200 to pick up the FPC to be tested, the second suction cup mounting plate is aligned with the loading and unloading module 200 to pick up the release paper, and then the transport drive mechanism 320 moves the transport adsorption mechanism 310 carrying the FPC and release paper to the test module 100 side; the vacuum suction cup 313 of the third suction cup mounting plate remains unloaded and is ready to receive the FPC after the test is completed.

[0055] In this embodiment, the coordinated rotation of three dedicated suction cup mounting plates 312 enables the simultaneous handling of three functions—picking up the FPC to be tested, transporting the release paper, and unloading the tested FPC—within the same handling cycle, significantly shortening the equipment cycle time and improving testing efficiency. The angled suction cup mounting plate 312 structure ensures that each adsorption surface does not interfere with each other during rotation, and the overlapping and fixing of adjacent suction cup mounting plates 312 through connecting plate parts 3123 enhances the overall rigidity. The symmetrical distribution around the rotation center of the first rotating drive component 311 ensures stability during rotation. The three adsorption surfaces have clearly defined functions, avoiding cross-contamination or suction force mismatch problems caused by using the same set of vacuum suction cups 313 to adsorb different materials.
