Technical Field
[0001] This utility model relates to the field of FPC technology, and in particular to an FPC thrust testing fixture. Background Technology
[0002] As electronic products become thinner, smaller, and denser, flexible printed circuit boards (FPCs) are widely used in smartphones, wearable devices, automotive electronics, and other fields due to their advantages such as bendability, light weight, and thinness.
[0003] The reliability of FPC connections directly affects the performance and lifespan of electronic products, making thrust testing of its connection terminals crucial.
[0004] In the existing technology, the existing FPC thrust testing method mainly adopts manual operation, which uses a handheld thrust machine to test the FPC attached to the fixture. However, manual operation is slow and it is difficult to ensure precise angle control of the handheld thrust machine, thus affecting the accuracy of the thrust test. In addition, the handheld thrust machine is prone to damaging the FPC. Utility Model Content

[0023] Please see Figures 1 to 2The FPC thrust testing fixture in this embodiment includes a base 10, a test component 20 disposed on one side of the top of the base 10, and a fixing component 30 disposed on the side of the top of the base 10 away from the test component 20 for fixing the FPC. The test component 20 includes a base plate 211 disposed on the base 10, a sliding structure 21 disposed on the base plate 211, and a thrust mechanism structure 22 connected to the sliding structure 21 for testing the FPC. The sliding structure 21 includes a slide rail 212 disposed on the base plate 211, a lead screw 213 disposed on the base plate 211, and a drive structure 214 disposed at the end of the lead screw 213 away from the fixing component 30 for driving the lead screw 213. The slide rail 212 is arranged parallel to and spaced apart from the lead screw 213. A sliding component 215 is slidably arranged on the slide rail 212. A nut seat is threadedly connected to the lead screw 213. A slide plate 216 is connected to the top of the nut seat and the sliding component 215. The thruster structure 22 is threadedly connected to the top of the slide plate 216. The thruster structure 22 includes a thruster body 221 threadedly connected to the top of the slide plate 216 and a pusher head structure 222 threadedly connected to the output end of the thruster body 221. The pusher head structure 222 includes a connecting part 223 threadedly connected to the output end of the thruster body 221 and a stop part 224 connected to the connecting part 223 on the side away from the thruster body 221 for abutting against the FPC.
[0024] Furthermore, a button 225 for controlling and adjusting the thruster body 221 is provided on the side of the thruster body 221 away from the base plate 211, and a display 226 for displaying real-time thrust is provided on the side of the button 225 facing the fixed component 30.
[0025] Understandably, the operator can set the test parameters of the thruster body 221 as needed using the button 225, and can observe the real-time thrust using the display 226.
[0026] Furthermore, an adhesive portion 38 for fixing the FPC is provided at the center of the top of the base 32.
[0027] Furthermore, a start / stop button 11 for controlling the drive structure 214 is provided on the side of the base 10 adjacent to the fixing component 30, and adjustment buttons 12 for controlling the rotation direction of the drive structure 214 are provided on both sides of the start / stop button 11.
[0028] Furthermore, the fixing component 30 includes a track 31 disposed on the top of the base 10, a base 32 slidably disposed on the track 31, and an abutment structure 33 disposed on the end of the base 32 away from the sliding structure 21 for abutting against the base 32.
[0029] Furthermore, the abutment structure 33 includes an abutment member 34 for abutting against the base 32, an abutment wall structure 35 disposed on the end of the base 32 away from the sliding structure 21, and a rocker structure 36 threadedly connected to the abutment wall structure 35 for driving the abutment member 34.
[0030] It should be noted that the rocker structure 36 penetrates the abutment wall structure 35.
[0031] Understandably, after the FPC whose thrust needs to be tested is fixed by attaching it to the adhesive part 38, the operator adjusts the drive structure 214 to rotate counterclockwise using the adjustment button 12 and drives the drive structure 214 to rotate the lead screw counterclockwise using the start / stop button 11. This causes the nut seat to move the slide plate 216 along the slide rail 212 towards the fixing assembly 30 via the sliding member 215 at the bottom. This, in turn, moves the thrust generator body 221 towards the FPC whose thrust needs to be tested. By shaking the rocker arm structure 36 clockwise, the abutment 34 moves towards the base 32, and the abutment 34 pushes the base 32 towards the thrust generator body 221 along the track 31. 21. Move the thruster body 221 to avoid insufficient stroke at the output end of the thruster body 221; after adjusting the distance between the thruster body 221 and the base 32 to within the stroke range of the output end of the thruster body 221, set parameters on the thruster body 221 via the button 225 and drive the thruster body 221 so that the output end of the thruster body 221 drives the push head structure 222 to move toward the fixed component 30, and perform thrust testing on the terminals of the FPC that needs to be tested according to the set parameters. During this process, the real-time thrust can be observed through the display 226, thereby increasing work efficiency, avoiding the impact of handheld thruster on the accuracy of thruster force testing, and avoiding damage to the FPC caused by handheld thruster testing.
[0032] It should be noted that the thruster body 221 described in this embodiment is an electronic thrust sensor.
[0033] Furthermore, the abutment structure 33 also includes a locking nut 37 threadedly connected to the rocker structure 36 for fixing the rocker structure 36, and the locking nut 37 is disposed on the side of the abutment wall structure 35 away from the base 32.
[0034] Understandably, by setting the locking nut 37, the base 32 is prevented from sliding during the thrust test.
[0035] It should be noted that when a mechanical thrust meter is used, after the FPC to be tested for thrust is fixed by attaching it to the adhesive part 38, the operator adjusts the drive structure 214 to rotate counterclockwise using the adjustment button 12 and drives the drive structure 214 to rotate the lead screw counterclockwise using the start / stop button 11. This causes the nut seat to move the slide plate 216 along the slide rail 212 towards the fixing assembly 30 via the sliding part 215 at the bottom. This moves the mechanical thrust meter towards the FPC to be tested for thrust. By shaking the rocker structure 36 clockwise, the abutment 34 moves towards the base 32, and the abutment 34 pushes the base 32 along the track 31 towards the mechanical thrust meter, preventing the FPC from not being able to abut against the test end of the mechanical thrust meter. After the thrust test of the FPC is completed, the rocker structure 36 is shaken counterclockwise to move the abutment 34 towards the base 32.
[0036] Furthermore, the abutment portion 224 is in the shape of an inverted trapezoid.
[0037] Understandably, the inverted trapezoidal design can better distribute stress, reduce local wear, and extend the service life of the abutment part 224.
[0038] In summary, the FPC thrust testing fixture in the above embodiments of this utility model, after fixing the FPC to be tested for thrust using a fixing component, drives the lead screw to rotate through a drive structure. This causes the nut seat to move the slide plate along the slide rail towards the fixing component via the sliding component at the bottom, thereby moving the thrust machine body towards the FPC to be tested, thus avoiding insufficient stroke at the output end of the thrust machine body. After moving the thrust machine body towards the FPC to be tested, parameters are set on the thrust machine body and it is driven to make the output end of the thrust machine body drive the push head structure towards the fixing component. The thrust is then tested on the terminals of the FPC to be tested according to the set parameters, thereby increasing work efficiency, avoiding the impact of hand-held thrust machine on the accuracy of thrust force testing, and preventing damage to the FPC caused by hand-held thrust machine testing.
