METHOD AND APPARATUS FOR DETECTING TAB

Disclosed are a method and an apparatus for detecting a tab. The method includes: determining that a first tab of a first electrode plate in a plurality of electrode plates of a first electrode assembly reaches a first position in an image collection area, wherein the plurality of electrode plates move toward the image collection area along a vertical direction; and collecting image information of the first tab, wherein the image information of the first tab is used to determine a state of the first tab. The tab detection method provided is able to completely detect the size and shape of the tab while avoiding adverse effects of the detection process on the state of the tab, so that the detection efficiency can be improved while improving the detection effect.
