Problems solved by technology

At present, the lug cutting path existing on the market is divided into the tab area and the straight line area. The two areas are cut with the same parameters. There will be quality problems such as burrs and metal spikes in the cut position, and these quality problems will pierce the isolation film. Causing short circuit between cathode and anode will bring great process quality problems to battery production and seriously affect the quality performance and safety performance of battery products

Abstract

The invention relates to the technical field of battery machining and specifically discloses a tab machining method. The tab machining method comprises the steps that raw materials are placed on a feeding mechanism to be fed; and a cutting mechanism cuts the raw materials according to a preset n_shapedcutting path, wherein the cutting mechanism adopts different actual technical parameters to cut the raw materials in different stages of the n_shapedcutting path. The tab machining method provided by the invention has the advantage that the cutting quality of the tab can be effectively improved because the cutting mechanism adopts the different actual technical parameters in the different stages of the n_shapedcutting path.

Description

technical field [0001] The invention relates to the technical field of battery processing, in particular to a tab processing method. Background technique [0002] Tabs are an integral part of lithium-ion polymer battery products. For example, mobile phone batteries, bluetooth batteries, and notebook batteries used in our daily life all need to use tabs. The battery is divided into positive and negative poles, and the tabs are the metal conductors that lead the positive and negative poles out of the battery. In layman's terms, the ears of the positive and negative poles of the battery are the contact points when charging and discharging. This contact point is not the copper piece we see on the outside of the battery, but a connection inside the battery. [0003] Both new energy vehicles and mobile devices need to achieve fast charging and fast discharging energy transfer. Fast charging and fast discharging require the battery to have multiple contact points for charging and...
