Abstract

The invention discloses a battery cell tab detection mechanism which comprises a bottom plate, a first moving platform, a first visual camera, a first prism, a first lifting device, a second moving platform, a second visual camera, a second prism and a second lifting device. The first moving platform and the first visual camera are arranged on the bottom plate in a front-back spaced mode. Visual detection is performed on the inner and outer side faces of the first tab and the inner and outer side faces of the second tab to detect whether the number of the first tab and the second tab is correct and whether the tabs are folded or not, compared with an existing manual identification mode, the visual detection efficiency is high, the false detection situation can be greatly reduced, and the detection efficiency is improved. And the quality of a battery cell product is effectively improved.

Description

technical field [0001] The invention relates to the technical field of battery cells, in particular to a detection mechanism for battery cell tabs. Background technique [0002] The battery cell is a raw material for lithium-ion polymer battery products. The battery cell is equipped with a pole ear, which is a metal conductor that leads the positive and negative electrodes out of the battery cell. For the ears of the negative poles, a battery cell will extend two tabs. The tabs are used as the contact point when the battery is charging and discharging, and the tabs include multiple tabs. [0003] In the production process of lithium batteries, whether the number of tabs of the battery cell is correct and whether the tabs are folded are important factors directly related to the quality of lithium battery products. Therefore, it is necessary to check whether the number of tabs of the battery cell is correct. Correct and whether there are abnormalities such as folding of the t...
