Cutting and forming device for battery pole piece with multiple coating tapes

Abstract

The invention provides a cutting and forming device for a battery pole piece with multiple coating tapes. The cutting and forming device for the battery pole piece with the multiple coating tapes comprises an emptying mechanism, a cutting mechanism, a roll-forming mechanism and a receiving mechanism arranged sequentially, wherein the cutting mechanism comprises a first laser die cutting assembly,a second laser die cutting assembly, a feed roller assembly and a discharge roller assembly; the first laser die cutting assembly is located on one side, close to the emptying mechanism, of the secondlaser die cutting assembly; the output end of the first laser die cutting module directly faces the feed roller assembly; the output end of the second laser die cutting module directly faces the discharge roller assembly; and the roll-forming mechanism comprises two press rollers arranged oppositely. According to the cutting and forming device for the battery pole piece with the multiple coatingtapes provided by the invention, excessive tension release occurred on the coating tapes can be avoided, so that the density of the coating tapes is effectively improved; all slitting actions are omitted, and cutting and roll-forming are integrated into a whole, so that the production efficiency can be effectively improved, and the input cost can be reduced; and through the two groups of laser diecutting assemblies, the distance between die cutting tool marks can be effectively shortened, so that the materials can be effectively saved.

Description

technical field [0001] The invention relates to the processing of battery pole pieces, and in particular discloses a cutting and forming device for battery pole pieces with multi-coating tapes. Background technique [0002] The battery pole piece is an indispensable component of the battery structure. After the battery pole piece is manufactured, it is wound to form a battery cell, and then the battery cell is put into the casing, and the electrolyte is injected after welding the cover plate, and finally the battery is packaged. . The performance of the battery is mainly related to the battery cell and the electrolyte, and the performance of the battery cell mainly depends on the performance of the battery pole piece. [0003] In order to improve the production efficiency of the battery pole piece, the battery pole piece is coated with multiple coating strips, and finally a single independent battery cell pole piece is obtained by slitting. In the prior art, the processing...

Problems solved by technology

In the prior art, the processing of battery pole pieces sequentially includes the following steps: coating, rolling, pre-slitting, die-cutting, and slitting into strips. This production process requires a lot of equipment, and the investment cost of the equipment is high. Moreover, each device works independently and needs to occupy an independent space. The material connection between each device needs to be carried by hand or conveyed by a conveyor belt. The labor cost and land cost are high, and the production efficiency is low. In addition, the coated belt after rolling The quality of the battery pole piece is affected by the lower density of the coated tape due to tension release
