Description

Technical Field

[0001] The utility model relates to a visual inspection device, in particular to a six-sided inspection device for square coated batteries. Background Art

[0002] The existing inspection of coated batteries has problems such as low efficiency, high labor cost, low accuracy, and large floor area.

[0003] At present, when producing square batteries, a blue film needs to be coated on them to play roles such as insulation, waterproofing, and aesthetics. Among them, after coating, there will be various appearance defects on the blue film of some batteries, such as film surface bubbles, film surface electrolyte, foreign objects in the film, wrinkles, shell pits, scratches, and damages, which affect the normal use of the batteries. Therefore, it is necessary to perform appearance defect inspection on the batteries before and after coating the blue film. The existing inspections for the appearance of the battery blue film are as follows:

[0004] 1) Adopting the method of manual inspection, the average time required to inspect one battery by this manual inspection method is about 18s, and it is necessary to manually inspect the square batteries one by one. The inspection efficiency is low, the labor cost is high, and there are situations of misdetection and missed detection due to subjective factors such as visual fatigue.

[0005] 2) Manual inspection and machine automatic inspection. Manually, with the help of a high-precision camera, the surface features of the battery blue film are magnified through a display screen, and the quality of the feature points is judged manually. This inspection method cannot distinguish between film surface bubbles and foreign objects in the film and is prone to misdetection because a single type of camera is selected for inspection and it is difficult to make an accurate judgment with single-sided imaging.

[0006] 3) The detection line of machine automatic detection is too long, resulting in a large floor area. The distance between the loading position and the unloading position is too far. In order to improve efficiency, it is necessary to arrange staff at the loading position, the unloading position, and the intermediate detection flow channel, resulting in too high labor cost.
