[0033] Optionally, the main Z-axis moving assembly includes a first vertical drive unit 11, a first vertical guide rail 12, and a first vertical slider 13 that slides with the first vertical guide rail 12; the lifting end of the first vertical drive unit 11 is connected to the first vertical slider 13, and the first vertical slider 13 is connected to the top of the rotating unit 8.

[0034] Vertical sensors 10 and buffers 9 are provided on the outer sides of both the upper and lower ends of the first vertical guide rail 12.

[0043] The working principle of this utility model:

[0044] The first vertical drive unit 11 can cause the first vertical flower to move up and down along the Z-axis (vertical direction). The first vertical drive unit 11 can be driven by a telescopic mechanism such as a cylinder or an electric cylinder. The first vertical guide rail 12 is set on one side of the first vertical drive unit 11. The first vertical slider 13 can move up and down along the first vertical guide rail 12. At the same time, vertical sensors 10 are set at the top and bottom of the first vertical guide rail 12 to detect the displacement of the first vertical slider 13. Buffers 9 are set at the top and bottom of the first vertical guide rail 12 to prevent the first vertical slider 13 from detaching from the first vertical guide rail 12 or to buffer the impact of the vertical movement of the first vertical slider 13, thereby preventing the clamping component from colliding with the battery cell or reducing damage.

[0045] The rotating unit 8 can be driven by a motor or cylinder to rotate the clamping mounting plate 1, thereby causing the entire clamping assembly to rotate. The clamping drive unit 2, the top pressure lifting unit 6, and the anti-collision lifting unit can all be driven by cylinders, electric cylinders, or other driving mechanisms. The clamping drive unit 2 causes the first clamping arm 3 and the second clamping arm 4 to move closer together or separate. The top pressure lifting unit 6 causes the fixed pressure plate to move up and down to press the battery or cell. The anti-collision lifting unit can drive the clamping plate 5 to move up and down. The fixed sensing unit 20 and the follow-up sensing unit 21 exchange signals. When the follow-up sensing unit 21 moves beyond a certain range with the clamping plate 5, the anti-collision lifting unit can immediately drive the clamping plate 5 to move up and down to adjust its vertical height. When the clamping plate 5 collides, the elastic connector 18 can buffer the impact of the collision. The fixed pressure plate and the clamping plate 5 are made of PEEK material, which is more durable than the traditional rubber coating process, has lower processing costs, higher wear resistance and strength, and completely eliminates the risk of metal contact with the cell after the rubber coating is damaged. The support member 14 and the protruding plate 15 are provided to support the electrode tabs and prevent them from sagging and colliding. The protective cover can effectively protect the fixed sensing unit 20 and prevent the clamping mounting plate 1 from being damaged by collision during the descent process.

[0046] This invention can automatically determine whether the clamping component collides with the battery cell through the vertical sensor 10, the fixed sensing unit 20, and the follow-up sensing unit 21. After a collision, the clamping component will automatically and instantly retract to protect the battery cell from damage and the gripper mechanism from being damaged. In the event of a collision, the buffer 9 can also mechanically retract to greatly reduce the impact force, thus achieving a better protective effect.

[0047] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
