Abstract

The invention relates to the technical field of tab processing and particularly discloses a method and device for detecting the folding condition of tabs. The method comprises a step of stacking and aligning a plurality of electrode pole pieces with the same shape and size from the top to the bottom, wherein the electrode pole pieces comprise pole piece bodies and tabs, and all the tabs are stacked into a tab group, a step of obtaining a stacking image corresponding to a stacking side surface of one end of the tab group away from the pole piece bodies, a step of obtaining the number of tab layers in the stacking image, and a step of determining the number of bent tabs in the tab group according to the number of the tab layers. The invention provides a method and a device for detecting thefold of the tabs, the folding condition of the tabs can be detected, and possible subsequent accident risks are avoided.

Description

Technical field

[0001] The invention relates to the technical field of tab processing, in particular to a method and device for detecting the folding of tabs. Background technique

[0002] Lithium-ion batteries generally include positive pole pieces and negative pole pieces. Take the positive pole piece as an example for illustration, see figure 1 The positive pole piece generally includes a pole piece body 1 coated with an active material and a lug 2 on the top of the pole piece body 1. The lug 2 is obtained by cutting the pole piece body 1 through a die-cutting process on the production line. It is trapezoidal. Generally, the connecting corner between the tab 2 and the active material on the pole piece body 1 is a circular arc angle 3.

[0003] It is understandable that in the production line, the pole piece main body 1 is often continuous and is driven by a driving roll, so it will be pulled forward, while the pole lug 2 mainly relies on its integration with the pole piece mai...
