Problems solved by technology

[0002] With the vigorous development of the new energy industry, the process requirements of new energy batteries are becoming more and more complex, especially the processing technology of soft pack batteries. On the one hand, customers require tabs to be cut into irregular shapes; on the other hand, soft pack battery aluminum The plastic film is easily scratched and leaks liquid, which is prone to safety accidents
However, ordinary mechanical cutting and tooling are difficult to cut the tab shape required by customers, and it is easy to cause excessive burrs and tab waste splashes during cutting, which is difficult to meet the diverse needs and safety requirements of pouch battery tab cutting

Abstract

The present invention provides a laser cutting tool and a laser cutting production line for soft-pack battery tabs. The laser cutting production line includes the laser cutting tool, and the laser cutting tool includes: a first fixing seat, a second fixing seat, an upper pressing assembly and a lower pressing assembly ;The lower pressing assembly includes a first driving mechanism, a movable seat, an overturning driving mechanism and a movable pressing block, and the movable pressing block is provided with chip blanking holes and air holes; Cut path holes. After the pouch battery arrives at the station, the first driving mechanism drives the movable pressing block to move up to touch the tab, and the second driving mechanism drives the upper pressing structure to move down. After the tab is clamped together, the tab can be cut. The chip drop hole falls, and the tab waste is absorbed by the air hole. After the battery is moved out of the station, the movable pressing block is turned to the vertical position, and the suction hole blows air to make the tab waste fall. The laser cutting tool of the present invention can adapt to the diverse requirements of tab cutting and has high safety.

Description

technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a laser cutting tool for tabs of soft-pack batteries and a laser cutting production line. Background technique [0002] With the vigorous development of the new energy industry, the process requirements of new energy batteries are becoming more and more complex, especially the processing technology of soft pack batteries. On the one hand, customers require tabs to be cut into irregular shapes; on the other hand, soft pack battery aluminum The plastic film is easily scratched and leaks liquid, which is prone to safety accidents. However, ordinary mechanical cutting and tooling are difficult to cut out the tab shape required by customers, and it is easy to cause excessive burrs and tab waste splashes during cutting, which is difficult to meet the diverse needs and safety requirements of pouch battery tab cutting. Contents of the invention [0003] The techni...
