Then the first circular belt 344 and the second circular belt 345 can drive the shell 200 to move towards the direction close to the turnover guide mechanism 35, so as to convey the shell 200 to the turnover guide mechanism 35.

[0078] In combination Figure 15 and Figure 16As shown, the turnover guide mechanism 35 comprises a turnover guide block 351, a hook structure and a transition block 355.

In the embodiment, one side of the hook installation block 352 is provided with a rotating shaft 3521, and the rotating sleeve 353 is rotatably sleeved on the outer periphery of the rotating shaft 3521. The rotating sleeve 353 is provided with a hook bearing 3522 sleeved on the outer periphery of the rotating shaft 3521 to provide rotational support for the rotating sleeve 353. One end of the hook body 354 is connected with the rotating sleeve 353. In the embodiment, the rotating sleeve 353 is provided with a radial threaded hole, one end of the hook body 354 penetrates through the threaded hole and is threadedly connected with the threaded hole. One end of the hook body 354 is threadedly matched with two locking nuts 3542, one of which is located above the rotating sleeve 353 and abuts against the outer peripheral surface of the rotating sleeve 353, and the other is located below the rotating sleeve 353 and abuts against the outer peripheral surface of the rotating sleeve 353. The two locking nuts 3542 arranged can lock the hook body 354 and the rotating sleeve 353 together. The other end of the hook body 354 extends into the guide groove 3511 and is located above the end of the guide slope 3512 close to the conveying driven wheel 343, and the other end of the hook body 354 is provided with a hook claw 3541. The transition block 355 is L-shaped, and is arranged between the conveying driven wheel 343 and the turnover guide block 351 and fixed to the side of the turnover guide block 351 close to the conveying driven wheel 343. The top end of the transition block 355 is flush with the bottom of the guide groove 3511 and not higher than the upper surface of the first circular belt 344 and the second circular belt 345. This design facilitates the movement of the shell 200 on the first circular belt 344 and the second circular belt 345 to the top end of the transition block 355.

[0079] The upper side of the first circular belt 344, the second circular belt 345 and the transition block 355 is provided with a guide block 349, which partially penetrates the gap 3482 of the positioning baffle 348 and is arranged on the first side of the vertical plate 31. One end of the guide block 349 is adjacent to the overturning guide block 351, and the other end is provided with a guide inclined surface 3491. When the shell 200 is in a vertical state on the first circular belt 344 and the second circular belt 345, during the movement of the shell 200 driven by the first circular belt 344 and the second circular belt 345 towards the direction of the overturning guide mechanism 35, when the shell 200 contacts the guide inclined surface 3491, under the action of the guide block 349 and the first circular belt 344 and the second circular belt 345 driving the shell 200 to move towards the direction of the overturning guide mechanism 35, the shell 200 can be changed from a vertical state to a horizontal state. When the shell 200 is in a horizontal state on the first circular belt 344 and the second circular belt 345, the shell 200 can directly pass through the space between the guide block 349 and the first circular belt 344 and the second circular belt 345.

[0080] In actual application, when the shell 200 passes through the space between the guide block 349 and the first circular belt 344 and the second circular belt 345, under the driving of the first circular belt 344 and the second circular belt 345, the shell 200 can be moved to the top end of the transition block 355, so as to realize the conveying of the shell 200 to the overturning guide mechanism 35.

[0081] When the shell 200 moves to the top end of the transition block 355 and the opening of the shell 200 faces one end of the first conveying mechanism 34, under the pushing of the subsequent shell 200, the shell 200 will push the hook body 354, the hook claw 3541 and the rotating sleeve 353 to rotate in the counterclockwise direction, and will move downward along the guide inclined surface 3512, and finally enter the material falling groove 3513, at this time the opening of the shell 200 is upward. When the shell 200 moves to the top end of the transition block 355 and the opening of the shell 200 faces the overturning guide mechanism 35, at this time the hook claw 3541 will extend into the shell 200 through the opening of the shell 200. Under the pushing of the subsequent shell 200, the shell 200 will push the hook body 354, the hook claw 3541 and the rotating sleeve 353 to rotate in the counterclockwise direction, and at the same time the shell 200 can be overturned by the hook claw 3541, so that when the shell 200 moves downward along the guide inclined surface 3512 and enters the material falling groove 3513, the opening of the shell 200 is upward.

Then the second clamping assembly 414 is driven by the feeding translation linear module 412 to move so as to be located directly above the battery mounting seat 21, at the same time, the shell 200 on the battery mounting seat 21 is moved to the position corresponding to the battery cell feeding device 40, and the part of the shell 200 protruding from the top end of the battery mounting seat 21 is clamped by the shell entering guide mechanism 25, and then the two feeding clamping jaws 4135 and the battery cell 300 are driven by the feeding up-down cylinder 4133 of the second clamping assembly 414 to move downward to pre-press the battery cell 300 into the shell 200 through the shell entering clamping cavity of the shell entering guide mechanism 25, and then the two feeding clamping jaws 4135 are driven by the feeding clamping jaw cylinder 4134 of the second clamping assembly 414 to open to release the two needle guides 301 of the battery cell 300, and then the two feeding clamping jaws 4135 are driven by the feeding up-down cylinder 4133 of the second clamping assembly 414 to move upward to the initial position, so that the battery cell 300 after the whole round is pre-pressed into the shell 200 on the battery mounting seat 21.

[0107] While the battery cell 300 after the whole round on the whole round mechanism 42 is clamped by the second clamping assembly 414, the next battery cell 300 after the turning on the two turning clamping jaws 4342 can be clamped by the first clamping assembly 413 in the aforementioned manner, and while the battery cell 300 after the whole round clamped by the second clamping assembly 414 is pre-pressed into the shell 200 on the battery mounting seat 21, the clamped battery cell 300 can be placed on the whole round mechanism 42 by the first clamping assembly 413 in the aforementioned manner.
