[0029] Example 3

[0030] like Figure 1-Figure 3 As shown, a lithium battery defect detection device proposed by the present invention, compared with the second embodiment, the detailed structure of the flip assembly is recorded in this embodiment, which includes a mounting seat 13, a third telescopic device 14, a connecting block 15, a rack 16, a fixed seat 17, a rotating shaft 18, a gear 19, a clamping member 20 and an auxiliary member 21.

The lithium battery in the groove on the rotating plate 23 is brought close to the conveyor belt, and the suction is stopped by the suction cup 24 to place it on the conveyor belt. The lithium battery can be transported by the conveyor belt and its other end is inspected by the industrial camera 4. The method and steps are the same as those of the sorting component upstream. After both sides of the lithium battery are inspected, the possible defects on its surface are greatly reduced, thereby avoiding the quality of the lithium battery being affected by surface defects.
