The camera positioning assembly 410 faces the second working surface 230, and the camera positioning assembly 410 performs photographing positioning on the battery piece 110 on the second working surface 230. In addition, the camera positioning component 410 also has the function of detecting whether the battery slice 110 is broken or not, and the corner is unfilled. The laser head 420 faces the third working surface 240, and the laser head 420 grooves the battery piece 110 on the third working surface 240 according to a preset pattern. The appearance detection assembly faces the fourth working surface 250, and the appearance detection assembly can perform appearance detection on the battery piece 110 on the fourth working surface 250.

Optionally, a storage box 520 is arranged at the discharge port of the NG blanking mechanism 500, and the NG blanking mechanism 500 sucks and places the battery piece 110 with poor appearance in the storage box 520. This is convenient for accomodate the arrangement to bad battery piece 110 to carry out subsequent rework. It should be noted that the third suction cups 510 are identical to the first suction cups 330 and the second suction cups 340 in structure, and the two third suction cups 510 correspond to the two battery pieces 110 on the second conveyor belt 130. However, the two third suction cups 510 work independently and interfere with each other, so that when one of the battery pieces 110 has a poor appearance, the corresponding third suction cup 510 can only suck the bad battery piece 110 out, and the other normal battery piece 110 continues to be conveyed to the subsequent process by the second conveyor belt 130.
