The image acquisition assembly 2 is arranged on the support and can acquire real-time images of the battery piece 100. The image processing assembly 3 is in communication connection with the image acquisition assembly 2, the image processing assembly 3 stores a standard image of the standard battery piece 100, and can compare the standard image with a real-time image acquired by the image acquisition assembly 2 and output a comparison result.
Since the battery plate detection device is required to detect not only the defects of the battery plate 100 but also the types of the defects, the battery plate 100 needs to be fixed at a detection position, and the final result is prevented from being influenced by errors caused by position deviation. Therefore, after the battery piece 100 is transported to the detection position by the transport unit 4, the battery piece 100 is positioned by the positioning unit 1, and the interference due to the positional deviation can be maximally discharged.
