When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0065] The special-shaped battery is a product of the continuous improvement of people's production and living requirements. Our ever-changing electronic products, electric products, and wireless mobile products often encounter situations where traditional cylindrical or square batteries cannot be arranged. Therefore, the battery has to be "deformed" to be applicable. The special-shaped battery is a battery different from the fixed shape and belongs to a battery with a special shape. Due to the special shape of the special-shaped battery, it has more outer surfaces than traditional batteries. When detecting the special-shaped battery, traditional detection methods are all through manual detection. Due to the visual error in manual detection, it leads to missed detections and low efficiency. The present invention aims to provide an appearance detection device for special-shaped batteries to improve the detection accuracy and efficiency of special-shaped batteries.
