Document Type and Number:
WIPO Patent Application WO/2023/197117
Kind Code:
A1
Abstract:
Provided are a measurement method and apparatus for a tab. The method comprises: determining that a first tab of a first electrode sheet among a plurality of electrode sheets of a first electrode assembly reaches a first position in an image acquisition area (S301), wherein the plurality of electrode sheets move towards the image acquisition area along a vertical direction; and acquiring image information of the first tab (S302), wherein the image information of the first tab is used for determining the state of the first tab. By means of the provided measurement method for a tab, the size and shape of the tab can be completely measured, and adverse effects of the measurement process on the state of the tab can also be avoided, thereby improving the measurement efficiency while improving the measurement effect.
