In this process, the second elastic member 470 is stretched and deformed. Under the action of the second limit screw seat 441 and the second limit screw 442, the two clamping rods 420 are limited to stop moving after moving to the predetermined position, so as to avoid damage to the battery cell 20.
After the battery cell 20 is clamped, the first limit screw 342 moves to abut against the stopper 434, and under the cooperation with the first limit screw seat 341, the first abutting block 310 moves to a predetermined position along with the first fixing seat 340 and is limited to stop moving. The second abutting block 320 moves relative to the second slider 370 with the slider 170 in a direction approaching the winding needle 530 under the action of the driver 210 to abut against the second cam 512 and push the swing rod 510 to rotate clockwise, so that the push wheel 513 pushes the guide sleeve 540 in a direction away from the winding needle 530, and the winding needle 530 on the winding needle seat 520 is separated from the winding needle seat 520. In this process, the fourth elastic member 542 is compressed and deformed.
After the blanking of the battery cell 20 is completed, the driver 210 reversely drives the sliding seat 170, and the second elastic member 470, the third elastic member 435, and the fourth elastic member 542 are reset, so that the clamping jaw mechanism and the winding needle seat mechanism are both reset.
Therefore, the first abutting block 310 acts on the first cam 413 firstly through one power source, and the second abutting block 320 acts on the second cam 512 later, so that the clamping rod 420 is inserted into the winding needle 530, the battery cell 20 is clamped, and the winding needle 530 is separated from the battery cell 20, the structure is simple, the preparation is easy, the control process is simple, the cost is low, and the working efficiency of battery cell blanking can be improved.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
