Rapid cutting and stacking all-in-one machine for lithium batteries

Abstract

The invention relates to the technical field of lithium battery production, in particular to a lithium battery rapid cutting and stacking all-in-one machine which comprises a diaphragm unwinding unit, a diaphragm cutting mechanism, a pole piece forming unit, a pole piece transferring unit, a stacking unit and a battery cell collecting bin. The pole piece forming unit and the pole piece transferring unit convey pole pieces to the lamination unit, the pole pieces and diaphragms form electric chips in the lamination unit, and the electric chips are laminated in the battery cell collecting bin. The effects of controlling the thickness of a battery cell, cutting a diaphragm and guaranteeing the positions of the pole pieces are achieved, the effect of cutting and stacking the pole pieces of the lithium battery is achieved, and the working efficiency of the lithium battery is improved; and meanwhile, the movement of the manipulator between the stations is reduced, so that the damage of the pole piece in the moving process is avoided, and the production quality of the lithium battery cell is ensured.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a lithium battery fast cutting and stacking integrated machine. Background technique [0002] With the improvement of the quality of life, people increasingly rely on the use of portable electronic products, such as smart phones, tablet computers, etc., which require batteries in the electronic products to provide power. At the same time, lithium batteries are widely used in smartphones and tablet computers to provide electricity for electronic products. [0003] During the production process of lithium batteries, the pole piece roll material is divided into multiple pole pieces, and the pole pieces and separators are pasted together, and then the pole pieces are laminated. [0004] The prior art has the following deficiencies in the production process of lithium batteries: [0005] 1. The stacking device cannot directly form the pole piece when loading mater...

AI Technical Summary

Problems solved by technology

[0005] 1. The stacking device cannot directly form the pole piece when loading materials. The pole piece needs to be transferred in the transfer box before it can be connected to the pole piece forming equipment. During the transfer, the pole piece is easily damaged and affects the quality of the lithium battery. ;

[0006] 2. In different processes, different operations need to be carried out through multiple stations, but the movement of the pole piece between multiple stations is generally done by manipulators, which not only easily causes damage to the pole piece, It is also easy to cause displacement of the pole piece, resulting in low production quality of lithium batteries;

[0007] 3. In the production process of lithium batteries, the effect of controlling the thickness of the battery cells and cutting the diaphragm cannot be realized in the same device, resulting in low working efficiency of lithium batteries
