Problems solved by technology

[0003] At present, the tab forming methods commonly used in lithium battery factories include laser die punching, metal die punching, semi-automatic laser tab forming and laser single-side tab forming machines. They all have the same problem, that is, the cutting speed is slow and the efficiency is low. Low, so it is inevitable that there will be the problem of small slice output of related molding machines, low production capacity, low production capacity and many processes. This problem is a bottleneck for improving the output of battery manufacturing cell pole pieces and reducing costs.

Abstract

The invention discloses pole lug forming slitting equipment which comprises an unwinding device, a laser cutting device, a drive device, a slitting device and a winding device. A pole piece is expanded through the unwinding device and driven to enter the laser cutting device. The laser cutting device cuts the two sides of the pole piece. The cut pole piece is conveyed to the slitting device through the drive device. The slitting device slits the cut pole piece from the middle. The winding device winds the slit pole piece into a roll material. The pole lug forming slitting equipment has the beneficial effect of being high in efficiency.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a tab forming and cutting device. Background technique [0002] In the continuous tab forming process of lithium-ion power battery pole pieces, because the aluminum foil and copper foil pole pieces are continuous sheets, it is a very difficult problem to quickly and efficiently realize the variable-pitch bilateral tab forming process. At present, the tabs commonly used in lithium battery factories The forming method is to use laser knife die punching, semi-automatic laser tab forming or fully automatic laser tab forming machine to form the tab on one side, or to use metal knife die to punch the double-sided tab to form, and then use the slitting machine to cut. For two volumes. [0003] At present, the tab forming methods commonly used in lithium battery factories include laser die punching, metal die punching, semi-automatic laser tab forming and laser single-side tab forming machines....
