  • Patent number: 12182992
    Abstract: Disclosed is an apparatus for inspecting the appearance of a can for a secondary battery, which can obtain an image of the appearance of the can for the secondary battery and determine whether there is a defect. The apparatus for inspecting the appearance of a can for a secondary battery according to the disclosure obtains lateral images of a plurality of cans at once, and generates the lateral image for one can by extracting an area where each can is captured, thereby speeding up the inspection. Further, the lateral images of the can are obtained with light emitted in various combinations, thereby having an effect on improving the accuracy in defect diagnosis.
