Lithium battery electrode tab cutting and dust removal device and lithium battery electrode tab cutting device

Abstract

The embodiment of the application belongs to the technical field of lithium battery cutting, and relates to a lithium battery electrode tab cutting and dust removal device and a lithium battery electrode tab cutting device. According to the technical scheme, the lithium battery electrode tab cutting and dust removal device includes a machine body, a dust removal pipe and a suction fan, wherein themachine body is provided with a dust removal cavity, a filter screen is arranged on the side, facing a processing area of the lithium battery electrode tab cutting device, of the dust removal cavity,the dust removal pipe is arranged on the side, opposite to the filter screen, on the dust removal cavity, and the dust removal pipe is connected with the suction fan, so that the dust removal cavitycan suck generated dust, and the dust can be timely and effectively removed by the dust removal cavity, an electrode is effectively protected against dust pollution in the process of cutting a tab, and thus the quality of a lithium battery is effectively guaranteed; a material belt of the lithium battery electrode tab cutting device is adsorbed on a vacuum belt to prevent the material belt of thelithium battery electrode tab cutting device from jittering in the process of cutting the tab, so that the stability of cutting the tab is ensured.

Description

technical field [0001] The present application relates to the technical field of lithium battery cutting, and more specifically, to a lithium battery pole piece lug cutting dust removal device and lithium battery pole piece lug cutting equipment. Background technique [0002] At present, the lithium battery manufacturing industry is developing rapidly, but the lithium battery lug cutting technology has always been the traditional mechanical cutting method, which has the disadvantages of slow cutting speed, rough cutting edges, burrs or small gaps, and difficult to adjust the cutting shape , some of them change continuously, and there is no fixed step distance tab, and even cannot be realized. The recent rise of laser cutting lug equipment aims to effectively solve the above problems, especially for the situation of non-fixed step lugs and frequent or continuous changes in cutting shape. Laser cutting tabs have shown irreplaceable advantages, and laser cutting tab equipment ...

AI Technical Summary

Problems solved by technology

However, the current laser cutting tab equipment is generally faced with the huge dust pollution of the pole piece when the laser is cutting the tab, which affects the quality of lithium batteries, and faces risks in large-scale and extensive commercial use.
