Laser cutting equipment and cutting method for cutting tabs

Abstract

The invention discloses laser cutting equipment for a cutting electrode lug. The laser cutting equipment comprises an absorptive cutting mechanism, an emptying mechanism and a collecting mechanism, wherein the absorptive cutting mechanism comprises a cutting platform; a portal frame is arranged on the cutting platform; a sliding laser cutting device is arranged on the portal frame; the laser cutting device is provided with a laser head and a laser scanner; an adsorption device corresponding to the laser cutting device is arranged at the bottom of the cutting platform; the adsorption device is provided with a vacuum cavity and a vacuum pumping device; the vacuum pumping device is connected with the vacuum cavity, and is used for generating negative pressure inside the vacuum cavity; the vacuum cavity is provided with an adsorption hole; a battery pole piece is adsorbed onto the adsorption device through the adsorption hole under the negative pressure inside the vacuum cavity. A high electrode lug cutting speed and high quality can be realized, so that the working efficiency is increased.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a laser cutting device for cutting tabs and a cutting method thereof. Background technique [0002] At present, the most important part of lithium battery or lead-acid battery is the polar plate. The quality of the polar plate directly affects the performance and service life of the battery. The polar plate is cut into small pieces by cutting or stamping. The most primitive method is to adopt manual cutting, manually stack and fix the pole plates and cut them with a saw blade. The cutting efficiency of this method is low, the cutting quality cannot be guaranteed, and manual operation has certain potential safety hazards. Of course, die punching is still used at present. Compared with manual cutting, this method improves work efficiency, but die punching is easy to cause large burrs, which poses a great hidden danger to the safety of the battery. With the loss of the mold, the consisten...
