Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of square aluminum shell battery manufacturing equipment, and particularly relates to a square aluminum shell battery film coating defect detection machine. BACKGROUND

[0002] The square aluminum shell film-coated battery is hereinafter referred to as a film-coated battery 10A, please see the attached Figure 1 According to the posture of the top surface 11 facing upwards, the bottom surface 12 facing downwards, and the liquid injection port 113 facing forwards, the appearance of the film-coated battery 10A includes six outer surfaces, i.e., the top surface 11, the bottom surface 12, the left large surface 13, the right large surface 14, the front surface 15, and the rear surface 16. During the manufacturing process, an insulating film needs to be attached to the six outer surfaces of the aluminum shell of the bare battery to serve the purpose of electrical isolation, and also to serve the purposes of corrosion prevention and decoration. Only the positive pole 111, the negative pole 112, the explosion-proof window 114, and the two-dimensional code 115 on the middle part of the top surface 11 are exposed.

[0003] Generally, the insulating film strip is made into a film strip type, and an adhesive is prepared on the back of the insulating film strip. The material of the insulating film strip is polyethylene terephthalate, which is referred to as PET. The insulating film is generally 0.08-0.15 mm thick, and has excellent insulating properties, high-temperature resistance, flame resistance, heat dissipation, and stretching rigidity. The adhesive is one or more of polyvinylidene fluoride-hexafluoropropylene copolymer, polyvinylidene fluoride, polymethyl methacrylate, polyethylene oxide, polyacrylonitrile, polystyrene, polyvinyl acetate, polyvinylpyrrolidone, and polyurethane, and is 0.01-0.05 mm thick. The adhesive can be accelerated to solidify under ultraviolet light UV irradiation, and after solidification, has excellent insulating properties, wear resistance, weather resistance, folding resistance, flame resistance, and heat dissipation. The adhesive bonding strength can reach 1.5-7 MPa.

[0004] In the prior art, a whole insulating film strip is attached to some surfaces of a bare battery to obtain a film-attached battery, and then the remaining surfaces of the battery are folded and attached with the extended insulating film to obtain a film-coated battery 10A. Commonly used battery film coating types include U-shaped film attachment and back-shaped film attachment.

[0005] Battery film coating surface quality requirements:

[0006] (1) The surface of the insulating film is free of glue, bulges, bubbles, wrinkles, horns, warping, dirt, scratches, and damage.

[0007] (2) The surface of the positive pole 111, the negative pole 112, the explosion-proof window 114, and the two-dimensional code 115 on the top cover 11 is free of dirt, scratches, and damage.

[0008] Therefore, we have developed a square aluminum shell battery film coating defect detection machine. SUMMARY

[0009] The present application aims to provide a square aluminum shell battery film defect detection machine for detecting the surface defects of the film battery.
