One end of the torsion spring 202c is fixedly connected to one side of the fixing ring 202b, and the other end of the torsion spring 202c is fixedly connected to one side of the sprocket 202.

[0034] Furthermore, the placement table 101 includes a top plate 101a, a rectangular plate 101b, and a baffle 101c. The top plate 101a is fixedly connected to the top of the placement table 101. The rectangular plate 101b is fixedly connected to one side of the top plate 101a. The baffle 101c is connected to the rectangular plate 101b, and the motor 102 is fixedly connected to the bottom of the baffle 101c.

[0035] Furthermore, the rectangular plate 101b includes a chute 101b-1, a threaded hole 101b-2, and a moving member 101b-3. The chute 101b-1 is opened through the top of the rectangular plate 101b. The threaded hole 101b-2 is opened on the top of the rectangular plate 101b. The moving member 101b-3 cooperates with the chute 101b-1.

[0036] Furthermore, the moving member 101b-3 includes a slider 101b-3a, a fixing plate 101b-3b, and a bolt 101b-3c. The slider 101b-3a is slidably connected to the chute 101b-1. The fixing plate 101b-3b is fixedly connected to the outside of the slider 101b-3a. The bolt 101b-3c passes through the fixing plate 101b-3b and is in threaded cooperation with the threaded hole 101b-2. The baffle 101c is fixedly connected to the bottom of the slider 101b-3a.

[0037] Furthermore, the motor 102 includes a lead screw 102a and a threaded block 102b. The lead screw 102a is fixedly connected to the output end of the motor 102. The threaded block 102b is threadedly connected to the lead screw 102a.

[0038] Furthermore, a first limit table 103 is fixedly connected to the top of the placement table 101. The first limit table 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 horizontal direction of the sliding rod can be telescopic.

[0040] Furthermore, the threaded block 102b includes a plug-in platform 102b-1, a side connection plate 102b-2, a connection block 102b-3, and a rack 102b-4. The plug-in platform 102b-1 is fixedly connected to one side of the threaded block 102b, the side connection plate 102b-2 is fixedly connected to one side of the threaded block 102b, the connection block 102b-3 is fixedly connected to one side of the side connection plate 102b-2, and the rack 102b-4 is fixedly connected to the bottom of the side connection plate 102b-2.

[0042] It should be noted that the vertical direction of the telescopic rod 104a is the telescopic direction.

[0043] When in use, first place one side of the integrated circuit board at the lower end of the pressing platform 104, turn on the motor 102, the output end of the motor 102 drives the lead screw 102a to rotate clockwise, 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 be inserted 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.

[0044] Embodiment 2

[0045] Refer to Figure 1 - Figure 6 Based on the first embodiment, this embodiment provides an integrated circuit testing and pressing device, wherein the positioning table 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 table 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 is convenient for separating the rack 102b-4 from the gear 201b so that the staff can repair its wear degree.

[0047] In addition, when the rack 102b-4 meshes with the gear 201b, the torsion spring 202c can provide a preloading force for the gear 201b and rack 102b-4 system, ensuring a tight mesh between the gear 201b and the rack 102b-4, reducing clearances and backlash, thereby improving the accuracy and stability of the transmission. At the same time, it has a certain shock absorption and impact absorption function. 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 pin 202a-2. The translation plate 202a-1 is fixedly connected to the other end of the chain 202a. The pin 202a-2 is fixedly connected to one side of the translation plate 202a-1. The pin 202a-2 cooperates with a notch formed on one side of the pressing table 104. A second limiting table 202d is fixedly connected to the top of the placement table 101. The translation plate 202a-1 is slidably engaged with the second limiting table 202d.

[0049] In addition, Figure 1 - Figure 6 This is only a reference schematic diagram for mechanical transmission and does not represent the final product ratio.

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

[0051] It should be noted that during the insertion process of the insertion table 102b-1 and the integrated circuit board, the pressing table 104 does not exert pressure on the integrated circuit board. During insertion, the pin 202a-2 engages with the notch, and the position of the integrated circuit board can be adjusted at any time during the non-insertion process.

[0052] In use, first place one side of the integrated circuit board at the lower end of the pressing table 104, and turn on the motor 102. The output end of the motor 102 drives the lead screw 102a to rotate clockwise. The lead screw 102a can drive the threaded block 102b to move downward. The threaded block 102b drives the insertion table 102b-1 to be inserted 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 rotates in reverse. 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 insertion table 102b-1 to rise. At this time, due to the engagement of the rack 102b-4 and the gear 201b, it can drive the gear 201b to rotate forward. 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 away from the second limit table 202d through the chain 202a. At this time, the spring 202d-2 is compressed, and the plug 202a-2 slides in the notch. During the process of the insertion table 102b-1 separating from the integrated circuit board, the plug 202a-2 does not separate from the notch. At this time, the telescopic rod 104a extends in the vertical direction. When the insertion table 102b-1 separates from the integrated circuit board, the plug 202a-2 slides out of the notch. At this time, the pressing table 104 loses the pressure on the integrated circuit board, and as the threaded block 102b moves upward a certain distance, it is convenient to perform circuit detection on the next integrated circuit board. The whole process does not require manual operation under the condition of a live circuit, avoiding the danger of electric shock and improving work efficiency, with better practicality.
