Abstract

The invention provides a tab forming method and relates to the technical field of battery manufacturing. A method for forming tabs, comprising the following steps: placing a material tape on a feeding device of a laser cutting machine, the material tape can move along with the feeding device according to a preset walking path of the material tape; the cutting device of the laser cutting machine follows a preset The laser walking path is set to cut the material belt, and the laser walking path is an "8"-shaped path; the cutting device can cut "" on the material belt moving according to the material belt walking path according to the laser walking path A few” shaped cutting path to cut tabs on the strip. Cutting the tape by adopting the laser cutting method of the "8" path effectively relieves the cutting method in the prior art which causes the laser cutting area to be large and the speed is fast, which makes the stability of the tape poor and affects the cutting accuracy and efficiency of the tabs, etc. question.

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 ...
