[0002] With the rapid development of new energy vehicles, my country is seeing an increasing number of them, and this has also led to numerous safety issues. The key to new energy vehicles lies in the power battery. Blade batteries, as the carrier of the entire battery, can exhibit various cosmetic defects during the manufacturing process, such as bubbles, bumps, wrinkles, scratches, dirt, and foreign matter in the coating. These defects can severely impact the filling, storage, and transportation of the chemical electrolyte, and consequently, the battery's proper operation. Therefore, blade batteries, after filling and coating, must be inspected for various cosmetic defects to eliminate potential safety hazards and ensure quality.

[0003] In the production of blade batteries, this highly repetitive and intelligent work is still generally completed by the naked eye; however, during the inspection process, there are many inspection surfaces, and workers simply cannot use the naked eye to carry out the inspection continuously and stably. Therefore, the stability and reliability of the inspection are poor, the work efficiency is low, and even misjudgment is prone to occur when the eyes are tired; in addition, some coated batteries are long and heavy, and it is difficult to inspect them manually; therefore, it is impossible to conduct comprehensive, accurate and detailed inspection and analysis of various types of defects in blade battery products. The problems of incomplete inspection and low inspection efficiency are also technical problems of existing battery product defect detection equipment. It is urgent to develop an efficient inspection equipment for coated blade batteries to solve the above problems and promote the rapid development of the new energy industry. Utility Model Content
