Abstract

The invention provides a tab forming method, and relates to the technical field of battery manufacture. The tab forming method includes the following steps that a material belt is placed on a feedingdevice of a laser cutting machine, wherein the material belt can move according to a preset material belt walking route along with the feeding device; a cutting device of the laser cutting machine cuts the material belt according to a preset laser walking route, wherein the laser walking route is a route shaped like the Arabic number '8'; and the cutting device can cut the material belt, moving according to the material belt walking route, to form an n-shaped cutting route according to the laser walking route so that a tab can be cut out on the material belt. By cutting the material belt in the laser cutting manner with the route shaped like the Arabic number '8', the problems that because of the cutting manner in the prior art, the laser cutting area is large, the laser cutting speed is high, the material belt stability is poor and the tab cutting precision and efficiency are accordingly influenced are effectively relieved.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a tab forming method. Background technique [0002] In traditional laser cutting equipment, the cutting track of the laser is continuous, and the laser completes the cutting of the tab through a continuous and symmetrical cutting path. [0003] Such as figure 1 As shown, in the traditional tab cutting method, the material tape (not shown in the figure) runs along a certain direction, and the laser cuts the tab along the direction of the arrow on the material tape. In the traditional process, when the laser cuts the tab, the laser goes through five paths to complete the cutting of the tab. Specifically, the laser in path 1 and 5 does not move at the origin, and the material tape moves by itself, cutting out the bottom lateral edge of the tab; path 2 and 4 pass through the change of laser speed (track) and superimpose with the speed (path) of the material tape Cut ...
