Laser cutting system for pole piece of power battery

Abstract

The invention discloses a laser cutting system for a pole piece of a power battery, which comprises an automatic loading subsystem, a laser cutting subsystem, an automatic finished product sorting subsystem and a control clip subsystem. The automatic loading subsystem conveys a partitioned pole piece material to the laser cutting subsystem, the laser cutting subsystem cuts the conveyed pole piece material according to a given size, the automatic finished product sorting subsystem fills the cut pole pieces and the rim charges into a finished product box and a waste recovery box, and the control clip subsystem intensively controls the automatic loading subsystem, the laser cutting subsystem and the automatic finished product sorting subsystem. The non direct contact and flexible processing of the laser cutting system thoroughly solve the problems of burrs and rim charge falling produced after cutting in modes of cutting of the prior punch cutting die and the like, the quality of the produced pole pieces is high, the sizes of the cut pole pieces are uniform, the equipment are easy to be maintained, the production cost is low and the efficiency is high. The laser cutting system is widely applied to a cutting process for the pole piece of the power battery.

Description

technical field [0001] The invention relates to a cutting system, in particular to a power battery pole piece laser cutting system. Background technique [0002] At present, the world's major automobile companies have launched a fierce competition in the field of new energy technology. The competition for the development and production of power batteries has entered a fierce stage. Compared with ordinary batteries, power batteries are characterized by large charging and discharging current and large capacity. With different specifications such as amp hours, 50 amp hours, 100 amp hours, and 300 amp hours, power batteries with higher power and larger capacity may appear as demand grows. The production of power batteries requires high-quality battery raw materials, suitable production processes, and strict process control. The number of positive and negative electrodes of the power battery varies from a few to hundreds of sheets, and they are stacked staggered. An insulating d...

AI Technical Summary

Problems solved by technology

The existing technology has the following disadvantages: 1. The edge burrs of the punched pole pieces are large, the edge material falls off, and there are many metal chips, so it is impossible to stably produce qualified battery pole pieces; 2. The cutting die is damaged quickly, and the cost of frequent replacement High; 3. It is difficult to adjust the die replacement, and the labor intensity of the operator is high; 4. After changing the die die, the dimensions of the pole pieces punched out are inconsistent, resulting in unstable battery capacity
