The positioning block 54 is able to enter the threaded hole 111 and is covered with a rubber sleeve at one end. The rubber sleeve on the positioning block 54 presses against the PCB board 11 of the BMS and will not cause damage to the PCB board 11 of the BMS.

[0049] Then, the transverse movement cylinder 44 is started, and the piston rod of the transverse movement cylinder 44 drives the transverse movement block 45 to move, and the adjusting cylinder 62 and the fixed block 53 on the transverse movement block 45 will move, and the first connecting block 51 on the fixed block 53 drives the first adjusting block 61 to move, and the first adjusting block 61 drives the sleeve 581 and the positioning block 54 to move; when the positioning block 54 contacts the PCB board 11 of the BMS, the chamfer on the positioning block 54 will cause the positioning block 54 to move upward, and the first spring 582 is compressed, and then the positioning block 54 contacts the PCB board 11 of the BMS, and then the sleeve 581 continues to drive the positioning block 54 to move; when the positioning block 54 is aligned with the threaded hole 111, the first spring 582 restores its elastic deformation, and the first spring 582 drives the positioning block 54 to move, so that the positioning block 54 enters the threaded hole 111; at this time, the first spring 582 is in a normal state, and then the transverse movement cylinder 44 is closed.

[0050] Then, the reinforcement block 31 is placed on the lifting block 43, and the third component block 313 contacts the lifting block 43; then the first motor 562 is started, so that the clamping block 55 on the first connecting block 51 and the clamping block 55 on the second connecting block 52 respectively contact the two second component blocks 312; then the second motor 576 is started, and the clamping block 55 on the first connecting block 51 and the clamping block 55 on the second connecting block 52 will drive the reinforcement block 31 to move, so that the reinforcement block 31 moves in the direction away from the fixed block 53.

[0051] When the clamping block 55 moves, the second component block 312 in the reinforcement block 31 will touch the interference block 5832 and push the interference block 5832 to move, and the interference block 5832 will drive the sliding block 5831 to move; when the sliding block 5831 moves, the sleeve 581 will move upward, and the sleeve 581 will drive the positioning block 54 to move; before the sliding block 5831 touches the second moving block 645, the positioning block 54 has been separated from the threaded hole 111. When the sliding block 5831 touches the second moving block 645 and pushes the second moving block 645 to move, the sleeve 581 still drives the positioning block 54 to move upward; when the first locking block 643 is engaged with the locking groove on the sleeve 581 and the second locking block 644 is engaged with the second locking groove on the sliding block 5831, the end of the positioning block 54 close to the lifting cylinder 42 is located above the third component block 313.

[0052] When the first locking block 643 is engaged with the locking groove on the sleeve 581 and the second locking block 644 is engaged with the second locking groove on the sliding block 5831, the adjusting cylinder 62 is started, and the piston rod of the adjusting cylinder 62 drives the fixed block 53 to move, and the first connecting block 51 and the second connecting block 52 on the fixed block 53 will move, and the clamping block 55 on the first connecting block 51 and the clamping block 55 on the second connecting block 52 drive the reinforcement block 31 to move toward the direction close to the female seat 21; when the fixed block 53 moves, the first adjusting block 61 moves in the direction away from the fixed block 53, so that the interference block 5832 on the first adjusting block 61 no longer touches the second component block 312. When the first through hole on the third assembly block 313 is aligned with the threaded hole 111 on the PCB board 11 of the BMS, the lifting cylinder 42 is activated to move the third assembly block 313 toward the PCB board 11 of the BMS and contact the PCB board 11 of the BMS. At this time, a portion of the pins on the pin header 23 will be located in the avoidance holes 3111 of the first assembly block 311, thereby reducing the loss of pins on the pin header 23 when installing the reinforcement block 31.

[0053] Because when the reinforcement block 31 is clamped by the two clamping blocks 55, the positions of different reinforcement blocks 31 relative to the clamping blocks 55 will be different, so the distance between the reinforcement block 31 and the sleeve 581 can be clarified, that is, the first locking block 643 is clamped and positioned with the first locking groove on the sleeve 581, thereby clarifying the distance between the reinforcement block 31 and the positioning block 54 on the sleeve 581. In this way, the stroke of each subsequent movement of the piston rod of the cylinder 62 is fixed, thereby achieving precise installation of the reinforcement block 31.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
