Laser cutting module for pole piece forming

Abstract

The invention relates to the field of automation equipment and discloses a laser cutting module for pole piece forming. The laser cutting module comprises a rack, multiple sections of cutting rolls and a laser light source. The cutting rolls and the laser light source are arranged on the rack. The multiple sections of cutting rolls comprise two or more rotary rolls and two or more static rolls. The rotary rolls and the static rolls are coaxial, are equal in diameter and are distributed at intervals in the axial direction. The static rolls are provided with grooves. The rotary rolls can rotate relative to the static rolls. The laser light source can emit laser beams toward the grooves. According to the laser cutting module, through matching of the multiple sections of cutting rolls and the laser light source, forming of a plurality of pole pieces can be conducted simultaneously, forming of the pole pieces does not need involve a plurality of stations, the cost of operation, management and intermediate storage is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to an automation equipment for producing lithium batteries, in particular to a cutting module for pole piece forming. Background technique [0002] The pole piece is one of the important structures on the battery, such as figure 1 As shown, the pole piece includes a base piece and tabs distributed on one side or both sides of the base piece. The raw material strip for making pole pieces is usually wider than a single pole piece, such as figure 2 As shown, there are several coating areas and blank areas spaced apart from each other on the raw material belt. At present, the production steps of the pole piece are to form the outline of the tab in the blank area by die-cutting, etc., and then form the outline of the substrate along the boundary line between the blank area and the coating area by die-cutting, etc., so as to realize Separation of pole piece and raw material belt. ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a laser cutting module for forming pole pieces, which can simultaneously form multiple pole pieces through the cooperation of multi-section cutting rollers and laser light sources, effectively solving the problems in the prior art. During the production process, the raw material belt needs to be transferred between different equipments, resulting in problems such as low production efficiency and high cost.
