Battery pole piece automatic punching machine and punching method thereof

Abstract

The invention provides an automatic battery pole piece punching machine, which includes a frame, a pole piece deviation correction and unwinding device, a pole piece tension device, a stamping transmission device, a traction device, a material receiving device, an overrolling device, and a pole piece installed on the frame. device, deviation correction and fixed length adjustment device, and pole piece deviation correction and unwinding device are used to install the pole piece. After the pole piece is unrolled, it passes through the pole piece tension device, overrolling device, correction and fixed length adjustment device, punching transmission device and traction device in turn. , the pole piece tension device is used to adjust the tension of the pole piece, the rolling device is used to maintain the position of the pole piece, the traction device is used to pull the pole piece coil out, and the deviation correction and length adjustment device is used to adjust the position of the pole piece For correction, the stamping transmission device is used to stamp the pole piece with a stamping die, and the material receiving device is arranged under the stamping transmission device to collect the stamped and formed pole piece. The battery pole piece automatic punching machine of the invention has the advantages of high product consistency and high production efficiency. The invention provides a punching method of a battery pole piece automatic punching machine.

Description

technical field [0001] The invention relates to the field of battery manufacturing equipment, in particular to an automatic battery pole piece punching machine for battery pole pieces and a punching method thereof. Background technique [0002] Lithium battery pole pieces are mostly formed by slitting and die-cutting methods, especially after die-cutting the pole piece with a laser knife, the pole piece has large burrs and is easy to drop powder. The lifespan is short, and the die-cut pole pieces cannot be collected. They can only be collected manually for the second time and stacked neatly to flow into the next process. The production efficiency is low and the labor consumption is large. Contents of the invention [0003] The object of the present invention is to provide an automatic battery pole piece punching machine and a punching method thereof, which can improve product consistency and production efficiency, thereby solving the above-mentioned technical problems. ...
