Project description:

        The battery manufacturer of this project requires the inspection of product appearance before shipment to ensure a "zero defect rate" of the shipped products. However, there are many types of defects in the appearance of prismatic cells, including blue film bubbles, dents and bumps, wrinkles, breakage, and 40 types of other defects; a wide variety of defects, including some defects requiring depth information; high acceptance requirements and the need to consider the size and depth of the defect area, which cannot be solved by the existing visual inspection solutions.

      Defect types:

    More than 40 types of defects, including blue film bubbles, white spots, bumps and dents, wrinkles, breakage, scratches, overlap width, height, surface foreign objects, warping, blue film fingerprints, fouling, and electrolyte leakage; pole scratches, stains, and welding slag; explosion-proof valve damage, fouling, leakage, PET film scratches, breakage, stains, and electrolyte leakage, etc. 

  Compared to traditional algorithms, AI algorithm achieves a 50% speed increase          Intelligent full inspection
