[0024] The rapid detection mechanism 5 includes a mounting frame 16, which is fixedly mounted on the bottom surface of the substrate 1, and a movable block 18 is slidably connected to the inner bottom surface of the mounting frame 16, and the height of the movable block 18 gradually increases from left to right. A first electric push rod 17 for driving the movable block 18 to move is fixedly mounted on one side of the inner side of the mounting frame 16, and one end of the telescopic shaft of the first electric push rod 17 is fixedly connected to one side of the movable block 18. A driving motor 19 for driving the support plate 6 to rotate is fixedly mounted on the bottom surface of the substrate 1, and the output shaft of the driving motor 19 penetrates The substrate 1 is fixedly connected to the bottom surface of the support plate 6, the top surface of the substrate 1 is provided with a mounting groove 22, the inner surface of the mounting groove 22 is movably sleeved with a push plate 23, the top surface of the support plate 6 is provided with a plurality of support grooves 20 for placing flexible circuit boards, the thickness of the flexible circuit boards is the same as the depth of the support grooves 20, the bottom surface of the support grooves 20 is provided with connection holes 21, the connection holes 21 are the same size as the mounting grooves 22, the bottom surface of the substrate 1 is elastically connected with a support rod 25, the inner bottom surface of the mounting groove 22 is fixedly installed with a shaft sleeve 24, the outer circumference of the support rod 25 is The wall surface is movably connected with the inner wall surface of the shaft sleeve 24, a fixing frame 27 is fixedly installed on the bottom surface of the support rod 25, and a roller 28 is rotatably connected inside the fixing frame 27. A spring 26 is movably connected to the outer wall surface of the support rod 25, one end of the spring 26 is fixedly connected to the top surface of the fixing frame 27, and the other end of the spring 26 is fixedly connected to the bottom surface of the substrate 1. Support shafts 29 are fixedly installed on both sides of the roller 28, and the support shafts 29 are rotatably connected to the fixing frame 27. The bottom surface of the mounting frame 16 is provided with a limiter for limiting the movable block 18. The limiting member includes a support hole 34, which is opened on the bottom surface of the mounting frame 16. A limiting block 11 is fixedly installed on the bottom surface of the movable block 18. A limiting rod 33 is fixedly installed inside the support hole 34. The limiting block 11 is slidably connected with the limiting rod 33.

[0025] Through the support plate 6, the staff puts multiple flexible circuit boards into the multiple support grooves 20 on the support plate 6 respectively, and the staff starts the drive motor 19. The output shaft of the drive motor 19 rotates to drive the support plate 6 to rotate. When the flexible circuit board of the support plate 6 rotates to the bottom surface of the test board 15, the test board 15 moves downward so that the pins on the test board 15 contact the flexible circuit board, thereby testing the power supply of the flexible circuit board. As the support plate 6 continues to rotate, the next flexible circuit board on the support plate 6 will rotate to the bottom surface of the test board 15 for testing again. At the same time, the tested flexible circuit board will rotate to the top of the mounting groove 22 on the substrate 1. At this time, the telescopic axis of the first electric push rod 17 moves forward to drive the movable block 18 to move forward on the mounting frame 16. The forward movement of the movable block 18 also causes the roller 28 to roll upward along the movable block 18, and at the same time, the roller 28 drives the support shaft 29 to rotate on the fixed frame 27 , the upward rolling of the roller 28 also causes the fixing frame 27 to drive the support rod 25 to move upward inside the shaft sleeve 24, and at the same time, the spring 26 is compressed. The upward movement of the support rod 25 will drive the push plate 23 to move upward, and the push plate 23 moves upward through the connecting hole 21 on the bottom surface of the support groove 20 on the support plate 6, thereby ejecting the tested flexible circuit board, which is convenient for the staff to remove the tested flexible circuit board, and then the telescopic shaft of the first electric push rod 17 contracts to reset the push plate 23. During this process, the multiple flexible circuit boards on the support plate 6 are rotated to the bottom of the test board 15 in turn for testing and the push plate 23 is used to allow the staff to easily take out the tested flexible circuit board. Compared with the prior art of testing one flexible circuit board each time, the number of flexible circuit boards that can be tested per unit time is increased, the speed of testing the flexible circuit board is improved, and the rapid testing effect of the flexible circuit board is achieved, which is convenient for the staff to test the flexible circuit board;

[0026] The top surface of the substrate 1 is provided with a mounting hole 30, the inner circular wall surface of the mounting hole 30 is rotatably connected with a fan 31 for limiting the position of the flexible circuit board, and the inner circular wall surface of the mounting hole 30 is fixedly sleeved with a dustproof net 32, which can filter dust in the air and reduce dust attached to the fan 31;

[0027] By setting the support plate 6, when the flexible circuit board in the support groove 20 on the support plate 6 rotates to the bottom surface of the test board 15, the rotation of the fan 31 will generate airflow, and the airflow will adsorb the flexible circuit board to be tested inside the support groove 20 through the mounting hole 30 and the connecting hole 21, thereby preventing the flexible circuit board from shaking during testing.

[0028] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, a testing device for an FPC flexible circuit board, which differs from the embodiment 1 in that a second electric push rod 35 for driving the test board 15 to move is fixedly installed on the inner bottom surface of the support frame 2, and the bottom surface of the telescopic shaft of the second electric push rod 35 is fixedly connected to the top surface of the test board 15. Through the second electric push rod 35, the telescopic shaft of the second electric push rod 35 moves downward to drive the test board 15 to move downward, thereby adjusting the position of the test board 15 according to the flexible circuit board;

[0029] A support plate 9 is fixedly installed on one side of the inner part of the support frame 2, and a movable mounting plate 10 is installed on the bottom surface of the support plate 9 through a threaded rod 14. A threaded hole is opened on the top surface of the support plate 9, and the inner circumferential wall surface of the threaded hole is threadedly connected with a threaded rod 14. The bottom end of the threaded rod 14 is rotatably connected to the top surface of the mounting plate 10 through a bearing. A sponge board 12 for wiping the flexible circuit board is detachably connected to the bottom surface of the mounting plate 10. The sponge board 12 can absorb the cleaning liquid required for cleaning the flexible circuit board. Two threaded columns 13 are fixedly installed on the top surface of the sponge board 12. One end of the threaded column 13 passes through the mounting plate 10 and a nut is threadedly connected to the outer circumferential wall surface.

[0030] Through the provided sponge board 12, the staff uses the sponge board 12 to absorb the cleaning liquid, and then the staff places the sponge board 12 on the bottom surface of the mounting plate 10 so that the threaded column 13 on the sponge board 12 passes through the mounting plate 10, and then the staff places the nut on the threaded column 13 and rotates the nut to install the sponge board 12 on the bottom surface of the mounting plate 10, and the staff rotates the threaded rod 14, and the rotation of the threaded rod 14 drives the bearing to rotate while the mounting plate 10 does not rotate. The rotation of the threaded rod 14 also causes the mounting plate 10 to drive the sponge board 12 to move downward until it contacts the top surface of the flexible circuit board. When the support plate 6 drives the flexible circuit board to rotate, the top surface of the flexible circuit board will contact the bottom surface of the sponge board 12, and the sponge board 12 can wipe the top surface of the flexible circuit board, thereby cleaning the dirt on the flexible circuit board, achieving the cleaning effect of the flexible circuit board, and avoiding the dirt on the flexible circuit board from affecting the test effect of the flexible circuit board;

[0031] A fixing block 7 is fixedly installed on the bottom surface of the supporting leg 3, and two fixing holes 8 are provided on the top surface of the fixing block 7. Through the setting of the fixing block 7, the staff puts the bolts into the fixing holes 8 on the fixing block 7, thereby installing the base plate 1 at a suitable position according to the needs.

Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
