Problems solved by technology

[0004] However, when the gap is just cut off, the laser generator will cut the tab and the battery pole piece continuously when cutting the tab, which will cause burrs on the shape of the tab, which will affect the performance of the battery cell.

Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a co-existence of an intervening component.

[0030] Unless otherwise defined, all technical and scientific terms used herein ...

Abstract

A method for cutting a battery electrode includes determining whether a portion of the battery electrode that is currently being cut is one of a plurality of electrode tabs or one of gap portions each being between two adjacent ones of the plurality of electrode tabs, and controlling one or more cutting parameters of a laser generator based on a determination result. The one or more cutting parameters of the laser generator are different for cutting the one of the electrode tabs from for cutting the one of the gap portions.

Description

technical field [0001] Embodiments of the present invention relate to the field of unmanned aerial vehicles, and in particular, to a method and equipment for cutting battery pole pieces. Background technique [0002] The discharge current of the UAV power battery is relatively large, so that the UAV power battery needs a cell with low internal resistance and good dynamic performance. The small internal resistance means that many tabs need to be set on the battery pole pieces. [0003] In the prior art, the battery pole piece is cut by a laser pole lug forming machine, which includes a laser generator, and the laser emitted by the laser generator cuts a plurality of pole lugs on the battery pole piece, and two adjacent pole lugs. In the gap between the ears, during normal production, the battery pole piece moves at a constant speed, and the laser power emitted by the laser generator is fixed. [0004] However, when the gap is just cut off, the tabs and the battery pole piec...
