The current cutting process of the lithium battery pole piece mainly comprises disc cutting, die cutting and laser cutting. The problems of cutter abrasion exist in disc cutting and die cutting, the process is easy to be unstable, the cutting quality of the pole piece is extremely poor, and the battery performance is reduced. The laser cutting has the characteristics of high production efficiency and good process stability, and the high-power density laser beam irradiates the cut pole piece to enable the pole piece to be rapidly melted, vaporized, burned or reach the melting point to form a hole; simultaneously, along with the movement of the laser beam on the pole piece, the holes continuously form slits with very narrow width, and the pole piece is cut. However, when the lithium battery pole piece is cut by laser, the pole piece can shake to cause incapability of cutting, and a lot of dust can be generated in the cutting process, so that the quality of the pole piece is affected.

In the prior art, in order to reduce the shake of a pole piece in the processing process, absorb dust generated by processing and improve the cutting quality, a most common method is to use a stable and controllable clamp.
