Abstract

The invention belongs to the technical field of battery manufacturing and relates to a battery cell polar piece making and winding all-in-one machine capable of cutting a polar piece at a high speed.The battery cell polar piece making and winding all-in-one machine comprises a polar piece conveying and cutting mechanism, wherein the polar piece conveying and cutting mechanism comprises a tractioncomponent and a cutting component arranged at the rear of the traction component. The polar piece conveying and cutting mechanism completes traction and cutting in a moving state respectively, and apolar piece cutter is utilized for driving a cam bit to drive a polar piece cutter follower, so as to realize rapid cutting of a polar piece cutter device, action is neatly, and section is tidy.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to an integrated battery sheet making and winding machine for high-speed cutting of pole pieces. Background technique [0002] The battery cell of a cylindrical lithium battery is a hollow cylinder formed by winding a positive electrode sheet, a negative electrode sheet, and two separators. The raw materials of positive electrode sheet, negative electrode sheet and separator are tapes. One positive electrode ear should be welded on the positive electrode sheet, and two negative electrode ears should be welded on the negative electrode sheet. The separator is used to separate the positive electrode sheet and the negative electrode sheet. Four coats of glue are required. The cutting and winding of the pole piece has a great influence on the quality of the battery cell, so the cutting mechanism before winding the pole piece in the past will be more complicated, and the e...
