Description

Technical Field

[0001] The present invention belongs to the field of optical detection, and particularly relates to a multi-angle detection device for steel shell batteries. Background Art

[0002] Steel shell batteries are a type of battery with a steel shell. Due to their high strength, corrosion resistance, detachable, replaceable, good stability and safety, they are widely used in mobile phone batteries, electric vehicles, energy storage systems and other fields.

[0003] For steel shell batteries formed by stamping, there are often defects such as cracks, scratches, sand holes or holes on their surfaces, especially at their corners and bottom surfaces. Conventional detection devices cannot detect well because the conventional detection mechanism is fixed and the detection camera is relatively fixed with respect to the battery to be measured. Therefore, it is difficult to complete the detection of multiple corners, sides and bottom surfaces in one station, resulting in low overall efficiency.
