[0038] Furthermore, a first limiting platform 103 is fixedly connected to the top of the placing platform 101, and the first limiting platform 103 is connected to the threaded block 102b through a sliding rod.

[0039] It should be noted that the first limiting platform 103 can limit the vertical direction of the threaded block 102b, and the sliding rod can be extended and retracted in the horizontal direction.

[0044] Example 2

[0045] Reference Figure 1 - Figure 6 Based on the first embodiment, this embodiment provides an integrated circuit test clamping device, wherein the positioning platform 201 includes a rotating shaft 201a, a gear 201b and a transmission rod 201c, the rotating shaft 201a is rotatably connected to one side of the positioning platform 201, the gear 201b is fixedly connected to one side of the rotating shaft 201a, one end of the transmission rod 201c is fixedly connected to the other side of the gear 201b, the circumferential surface of the transmission rod 201c is rotatably connected to the inner side of the fixed ring 202b, the other end of the transmission rod 201c is fixedly connected to one side of the sprocket 202, and the gear 201b cooperates with the rack 102b-4.

[0046] It should be noted that the position of the slider 101b-3b can be adjusted through the cooperation of the bolt 101b-3c and the threaded hole 101b-2, which makes it easy to separate the rack 102b-4 from the gear 201b so that the staff can inspect the degree of wear.

[0047] In addition, when the rack 102b-4 is meshed with the gear 201b, the torsion spring 202c can provide a preload force for the gear 201b and rack 102b-4 system, ensuring close meshing between the gear 201b and the rack 102b-4, reducing gaps and backlash, thereby improving the accuracy and stability of the transmission, and at the same time having a certain degree of shock absorption and impact absorption. During the meshing process of the gear 201b and the rack 102b-4, the transmission system may be impacted due to load changes or external shocks. The torsion spring 202c can absorb these shocks and reduce damage to the gear 201b and the rack 102b-4.

[0048] Furthermore, the chain 202a includes a translation plate 202a-1 and a latch 202a-2. The translation plate 202a-1 is fixedly connected to the other end of the chain 202a, and the latch 202a-2 is fixedly connected to one side of the translation plate 202a-1. The latch 202a-2 cooperates with a groove opened on one side of the pressing table 104. A second limit table 202d is fixedly connected to the top of the placement table 101, and the translation plate 202a-1 slides with the second limit table 202d.

[0049] in addition, Figure 1 - Figure 6 It is only a reference diagram of mechanical transmission and does not represent the final product proportions.

[0050] Furthermore, a displacement rod 202d-1 is slidably connected to the inner side of the second limit platform 202d, one side of the displacement rod 202d-1 is fixedly connected to the translation plate 202a-1, one side of the displacement rod 202d-1 is fixedly connected to a spring 202d-2, one end of the spring 202d-2 is fixedly connected to the inner wall of the second limit platform 202d.

[0051] It should be noted that during the plugging process between the plugging platform 102b-1 and the integrated circuit board, the pressing platform 104 does not exert pressure on the integrated circuit board. During the plugging process, the latch 202a-2 engages with the slot, and the position of the integrated circuit board can be adjusted at any time when not plugged in.

[0052] When in use, first place one side of the integrated circuit board on the lower end of the pressing table 104, turn on the motor 102, and the output end of the motor 102 drives the lead screw 102a to rotate clockwise, and the lead screw 102a can drive the threaded block 102b to move downward, and the threaded block 102b drives the plug-in platform 102b-1 to plug into the socket of the integrated circuit board on the upper end surface of the placement table 101 to detect whether the circuit of the integrated circuit board is normal. After the detection is completed, the motor 102b is reversed, and the output end of the motor 102b can drive the lead screw 102a to rotate counterclockwise. At this time, the threaded block 102b can drive the plug-in platform 102b-1 to rise. At this time, due to the meshing of the rack 102b-4 and the gear 201b, the gear 201b can be driven to rotate forward, and the gear 201b drives the sprocket 202 to rotate through the transmission rod 201c. The sprocket 202 can drive the translation plate 202a-1 to move in the direction away from the second limit platform 202d through the chain 202a. At this time, the spring 202d-2 is compressed, and the pin 202a-2 slides in the slot. During the separation of the plug-in platform 102b-1 from the integrated circuit board, the pin 202a-2 does not separate from the slot. At this time, the telescopic rod 104a extends in the vertical direction. When the plug-in platform 102b-1 is separated from the integrated circuit board, the pin 202a-2 slides out of the slot. At this time, the clamping platform 104 loses the pressure on the integrated circuit board and moves upward for a distance with the threaded block 102b, which is convenient for circuit detection of the next integrated circuit board. The whole process does not require manual operation in the passage, avoids the risk of electric shock, improves work efficiency, and has better practicality.
