A movable block 12 is threadedly connected to the outer wall of the threaded rod 8. The movable block 12 slides in the bottom of the groove 2. A rack 13 is fixedly connected to the top of the movable block 12. A fixing rod 5 is rotatably connected to the inner wall of the groove 2. Two sets of fixing rods 5 are symmetrically arranged. Gears 6 are fixedly connected to the outer wall of both sets of fixing rods 5. The gears 6 mesh with the rack 13. A drive plate 7 is fixedly connected to the top of the fixing rod 5. A first sliding groove 14 and a second sliding groove 15 are opened on the top of the support base 1. A movable column 18 is slidably connected in the first sliding groove 14. Two sets of movable columns 18 are symmetrically arranged. A clamping plate 17 is fixedly connected to the top of the two sets of movable columns 18. A limiting component is connected to one end of the threaded rod 8 to facilitate limiting the threaded rod 8.

[0031] The rotating assembly includes connecting rods 19, with two sets of connecting rods 19 symmetrically arranged. The two sets of connecting rods 19 are rotatably connected to the side of the clamping plate 17. One end of the connecting rod 19 is fixedly connected to a fixed plate 20. One end of one set of connecting rods 19 is fixedly connected to a worm gear 21. A connecting block 22 is fixedly connected to the side of one set of clamping plates 17. A worm 23 is rotatably connected inside the connecting block 22, and the worm 23 meshes with the worm gear 21. The limiting assembly includes a turntable 9, which is fixedly connected to one end of the threaded rod 8. A limiting hole 10 is formed inside the turntable 9, and a threaded groove is formed inside the fixed block 3. 4. A bolt 11 is threaded into the threaded groove 4, with one end of the bolt 11 passing through the limiting hole 10; a crank 24 is fixedly connected to one end of the worm gear 23; a limiting block 16 is fixedly connected to the bottom of the clamping plate 17, and the limiting block 16 slides in the second slide groove 15; a fixed frame 25 is fixedly connected to the top of the support base 1, and the camera 26 is connected to the top of the fixed frame 25, and the display screen 27 is connected to the top of the fixed frame 25. The camera 26 and the display screen 27 are electrically connected; the rack 13 is parallel to the support base 1, so that the gears 6 on both sides rotate smoothly.

[0032] Working principle: In the pin detection device for chip packaging, rotating the turntable 9 drives the threaded rod 8 to rotate, which in turn drives the moving block 12 to move, which in turn drives the rack 13 to move, which in turn drives the gears 6 on both sides to rotate, thereby driving the fixed rod 5 to rotate. The fixed rod 5 drives the drive plate 7 to rotate, which in turn drives the moving columns 18 on both sides to slide in the first slide groove 14. At the same time, the limiting block 16 slides in the second slide groove 15, causing the clamping plates 17 on both sides to move closer to the center. Bolts 11 are threaded through the corresponding limiting holes 10 and threaded into the threaded groove 4 to fix the position of the threaded rod 8, which facilitates the fixing of pins for different chip packages and improves stability during the detection process. To ensure the accuracy of the test data, when the turntable 9 is rotated in the reverse direction, the drive plate 7 moves to both sides. The operator only needs to manually move the clamping plate 17 outward to prepare for the next fixation. Turning the crank handle 24 drives the worm gear 23 to rotate, the worm gear 23 drives the worm wheel 21 to rotate, and the worm wheel 21 drives the connecting rod 19 to rotate, thereby driving the fixed plate 20 to rotate. This facilitates a comprehensive rotational test of the fixed and clamped pins without the need to change positions and re-fix them for testing, making it more convenient. The camera 26 takes pictures of the pins, and the pictures are transmitted to the display screen 27. The operator compares the pictures with those of qualified chip pins to check whether the chip pins are qualified, thus completing the test.
