The working steps of the appearance detection device for the square aluminum-shell battery are as follows:

(1) a square aluminum shell battery is vertically placed on the battery positioning module 2, one large surface of the battery is over against the large surface detection module 1, and the large surface scanning camera 15 scans the large surface of the battery;

(2) the battery positioning module 2 rotates the battery by 180 degrees, the other large surface is opposite to the large surface detection module 1, and the large surface scanning camera 15 scans the large surface of the battery;

(3) the transplanting overturning module 3 transfers the batteries in the battery positioning module 2 to a waiting station 42 of the lifting transplanting module 4, and the batteries are placed in an inclined mode with the large surfaces facing up and down;

(4) jacking subassembly 45 detects on the rotating assembly 47 of station 43 with the battery circulation, facet and edges and corners detection module 5 and vertical arris detection module 6 scan the battery and detect:

firstly, a small face and edge angle detection module 5 scans 1 small face and 2 transverse edges, a vertical edge detection module 6 scans 1 vertical edge, and a rotating assembly 47 drives a battery to rotate for 30 degrees;

the facet and corner angle detection module 5 scans 2 angles, and the rotating assembly 47 drives the battery to rotate 60 degrees;

repeating the first step and the second step until scanning detection of 4 small faces, 8 transverse edges, 4 vertical edges and 8 angles is completed;

(5) the jacking assembly 45 moves the batteries from the inspection station 43 to the completion station 44 for transfer to the next process.

The above examples are intended to illustrate rather than to limit the invention, and all equivalent changes and modifications made by the methods described in the claims of the present invention are intended to be included within the scope of the present invention.
