A laser punching machine

Abstract

The present invention relates to the technical field of lithium battery production, in particular to a laser punching machine, which includes positive electrode sheet forming equipment, negative electrode sheet forming equipment, and electrode sheet burr sampling equipment. Sheet conveying device, visual positioning device, pole piece transfer device, detection and adjustment workbench and burr detection device, pole piece sampling and feeding device supplies pole pieces to pole piece conveying device, visual positioning device visually locates pole pieces, and pole piece transfer The device transfers the pole piece to the detection and adjustment workbench, and the burr detection device performs burr detection on the pole piece. On-line sampling inspection of the positive electrode or negative electrode, it is not necessary to stop the positive electrode forming equipment and the negative electrode forming equipment during the sampling inspection, and it will not interfere with the normal operation of the positive electrode forming equipment and the negative electrode forming equipment, the degree of automation is high, and the burr detection efficiency is high. High quality, good quality, and reduce the labor intensity and labor cost of the operator.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a laser punching machine.

The large-scale application of lithium batteries in rapidly growing consumer electronics and other electronic products has greatly promoted the exp...

AI Technical Summary

Problems solved by technology

[0003] In the production process of lithium batteries, burr defects may occur in the die-cutting and slitting process of the pole piece. If the burr punctures the diaphragm used to separate the positive and negative plates, it will cause serious consequences, and at least it will cause battery leakage. The battery explodes

At present, the detection of pole piece burrs generally adopts manual sampling inspection, and the detection efficiency is low. In addition, random inspection may cause some burr defects to be missed and cause serious consequences, and the detection quality is poor.
