The flip clamping assembly includes a flip jaw cylinder 4341 and two flip jaws 4342. The flip jaw cylinder 4341 is arranged on the side of the flip cylinder plate 4322 away from the flip seat 432. The two flip jaws 4342 are both arranged at the bottom end of the flip jaw cylinder 4341 and located below the flip cylinder plate 4322. In actual application, the two flip jaws 4342 are located above the end of the battery cell conveyor line 400.

In this embodiment, the flip mounting plate 435 and the flip connecting plate 4313 are integrally formed, and an L-shaped structure is formed between the two. The flip mounting plate 435 is provided with an L-shaped flip cam groove 4351, and the cam follower 4324 cooperates with the flip cam groove 4351 and can move along the flip cam groove 4351.The flip upper and lower cylinders 433 are used to drive the flip seat 432 to move up and down, thereby driving the flip shaft 4321, the flip cylinder plate 4322, the cam mounting plate 4323, the flip clamp cylinder 4341 and the two flip clamps 4342 to move up and down. The up and down movement of the cam mounting plate 4323 can drive the cam follower 4324 to move along the flip cam groove 4351. During the movement of the cam follower 4324 along the flip cam groove 4351, the cam mounting plate 4323 can be driven to flip around the axis of the flip shaft 4321, thereby driving the flip cylinder plate 4322, the flip clamp cylinder 4341 and the two flip clamps 4342 to flip through the flip shaft 4321. The flip angle is 90 degrees. The flipping action is achieved by moving the cam follower 4324 along the flip cam groove 4351, without power, which can save power costs.

[0103] The flip cam groove 4351 includes a vertical section 4352 and a horizontal section 4353, wherein the horizontal section 4353 is located between the vertical section 4352 and the flip connecting plate 4313, and the horizontal section 4353 and the vertical section 4352 are smoothly transitioned through a circular arc transition section 4354. The circular arc transition section 4354 is provided to facilitate the cam follower 4324 to move from the vertical section 4352 to the horizontal section 4353 and from the horizontal section 4353 to the vertical section 4352.

[0104] In actual application, in the initial position, the cam follower 4324 is located in the middle of the vertical section 4352. When the battery cell 300 is transported to the bottom of the two flip claws 4342 of the battery cell flipping mechanism 43 through the battery cell conveying line 400, the battery cell 300 is in a horizontal state at this time. The flip seat 432 is first driven to move downward by flipping the upper and lower cylinders 433, thereby driving the two flip claws 4342 and the cam mounting plate 4323 to move downward, and then driving the cam follower 4324 to move downward along the vertical section 4352 until the cam follower 4324 is located in the lower end of the vertical section 4352. At this time, the battery cell 300 is located between the two flip claws 4342, and then the flip claw cylinder 4341 is used to drive the two flip claws 4342 to close to clamp the battery cell 300, and then the upper and lower cylinders 433 are driven to flip. The movable flip seat 432 moves upward, thereby driving the two flip jaws 4342, the battery cell 300, and the cam mounting plate 4323 to move upward, and further driving the cam follower 4324 to move upward along the vertical section 4352 until the cam follower 4324 enters the end of the horizontal section 4353 close to the vertical section 4352 through the arc transition section 4354. In the process of the cam follower 4324 entering the end of the horizontal section 4353 close to the vertical section 4352, the cam follower 4324 can drive the cam mounting plate 4323 to flip in the counterclockwise direction around the axis of the flip shaft 4321, thereby driving the two flip jaws 4342 and the battery cell 300 to flip in the counterclockwise direction through the flip shaft 4321, so that the battery cell 300 is in a vertical state, and at this time, the two guide pins 300 of the battery cell 300 are facing upward. Then, the first clamping assembly 413 and the second clamping assembly 414 are driven to move by the feed translation linear module 412, so that the first clamping assembly 413 is located directly above the battery cell 300 on the two flipping jaws 4342, and then the two feed jaws 4135 are driven to move downward by the feed upper and lower cylinders 4133 of the first clamping assembly 413 until the two guide pins 301 of the battery cell 300 on the two flipping jaws 4342 are located between the two feed jaws 4135 of the first clamping assembly 413, and then the first clamping assembly 413 is driven to move downward by the feed upper and lower cylinders 4133 of the first clamping assembly 413 until the two guide pins 301 of the battery cell 300 on the two flipping jaws 4342 are located between the two feed jaws 4135 of the first clamping assembly 413. The feed jaw cylinder 4134 of the component 413 drives the two feed jaws 4135 to close to clamp the two guide pins 301 of the battery cell 300, and then drives the two flip jaws 4342 to open to release the battery cell 300 through the flip jaw cylinder 4341, and then drives the two feed jaws 4135 and the battery cell 300 to move upward to the initial position through the feed upper and lower cylinders 4133 of the first clamping component 413. In this way, the flipped battery cell 300 on the battery flipping mechanism 43 can be clamped by the first clamping component 413.Then, the first clamping assembly 413 and the second clamping assembly 414 are driven to move by the feed translation linear module 412, so that the first clamping assembly 413 is located directly above the full circle mechanism 42, and the second clamping assembly 414 is located directly above the battery mounting seat 21. Then, the two feed clamping claws 4135 and the battery cell 300 are driven downward by the feed upper and lower cylinders 4133 of the first clamping assembly 413, so that the battery cell 300 is placed at the center of the top of the pneumatic finger cylinder 422 through the guide channel 4251. At this time, the two ends of the battery cell 300 are moved downward. The guide pin 301 partly protrudes from the top of the full-circle guide block 425, and the battery cell 300 partly is located in the guide channel 4251, and then the two feed jaws 4135 are driven to open by the feed jaw cylinder 4134 of the first clamping component 413 to loosen the two guide pins 301 of the battery cell 300, and then the two feed jaws 4135 are driven to move upward to the initial position by the feed upper and lower cylinders 4133 of the first clamping component 413, so that the clamped battery cell 300 is placed on the full-circle mechanism 42 through the first clamping component 413. At the same time, the flip seat 432 is driven to move downward by flipping the upper and lower cylinders 433, thereby driving the two flip jaws 4342 and the cam mounting plate 4323 to move downward, and then driving the cam follower 4324 to first enter the upper end of the vertical section 4352 through the arc transition section 4354, and then move downward along the vertical section 4352 to the initial position. In the process of the cam follower 4324 entering the upper end of the vertical section 4352, the cam mounting plate 4323 can be driven to flip in a clockwise direction around the axis of the flip shaft 4321 through the cam follower 4324, so that the two flip jaws 4342 can be driven to flip in a clockwise direction to the initial position through the flip shaft 4321, and then the next battery cell 300 conveyed through the battery cell conveyor line 400 is clamped and flipped according to the above steps.

[0105] Then, the first clamping component 413 and the second clamping component 414 are driven by the feed translation linear module 412 so that the first clamping component 413 is located directly above the next battery cell 300 after flipping on the two flipping jaws 4342, and the second clamping component 414 is located directly above the rounding mechanism 42. At the same time, the four clamping blocks 423 are driven by the pneumatic finger cylinder 422 to move toward the center of the top of the pneumatic finger cylinder 422 until they reach the predetermined position. At this time, the battery cell 300 is clamped by the four clamping blocks 423 and fixed in the circular cavity 4231. During the movement of the four clamping blocks 423, the battery cell 300 can be squeezed through the bottom of the arc groove 4233 of the four clamping blocks 423, so that the battery cell 300 can be rounded.

[0106] After the battery cell 300 is fully circled, the four pressing blocks 423 are driven by the pneumatic finger cylinder 422 to move in a direction away from the center of the top of the pneumatic finger cylinder 422 to loosen the battery cell 300, and then the two feeding jaws 4135 are driven downward by the feeding upper and lower cylinders 4133 of the second clamping assembly 414 until the guide pin 301 of the battery cell 300 is located between the two feeding jaws 4135 of the second clamping assembly 414, and then the second clamping assembly 4 The feed jaw cylinder 4134 of 14 drives the two feed jaws 4135 to close to clamp the two guide needles 301 of the battery cell 300, and then the two feed jaws 4135 and the battery cell 300 are driven by the upper and lower feed cylinders 4133 of the second clamping assembly 414 to move upward to the initial position. At this time, the battery cell 300 is located directly above the guide channel 4251. In this way, the battery cell 300 that has been rounded on the rounding mechanism 42 can be clamped by the second clamping assembly 414. Then, the second clamping assembly 414 is driven to move by the feed translation linear module 412 so that the second clamping assembly 414 is located directly above the battery mounting seat 21. At the same time, the battery mounting seat 21 drives the shell 200 thereon to move to a position corresponding to the battery cell feeding device 40, and the portion of the shell 200 protruding from the top of the battery mounting seat 21 is clamped by the shell entry clamping cavity of the shell entry guide mechanism 25.

The two second distance variable blocks 945 are symmetrical about the center line of the height direction of the second material grabbing and loading plate 938. Parts of the two second distance variable blocks 945 are respectively located between the driving plate 943 and the second material grabbing and loading plate 938.

Two second bearings 947 are respectively provided on one side of the two second distance variable blocks 945. The two second bearings 947 are located below the two first bearings 946 and correspond to the two avoidance grooves 9441 respectively. The driving plate 943 is provided with two second strip holes 9432 corresponding to the two second bearings 947 and the two first strip holes 9431 respectively.
