Description

Technical Field

[0002] In battery manufacturing equipment, especially after the pole piece's lug is die-cut, it is necessary to cut the pole piece with the completed lug die-cut after pulling the material. In the existing technical scheme, the pole piece is generally rolled and pulled by using rubber rollers and other rollers before cutting. In this process, the traction stability needs to be ensured, especially the need to prevent the pole piece from wrinkling when the material is pulled. The existing technical scheme generally adopts a method of directly connecting the drive device and the rubber roller. Under this direct connection method, the rubber roller is unstable during traction, which will cause the pole piece to wrinkle and affect the subsequent cutting of the pole piece. In addition, the size of the pole piece after cutting needs to be kept consistent. Therefore, how to achieve accurate cutting of the pole piece is also a problem that needs to be solved in the prior art. Summary of the invention
