[0002] At present, the country vigorously promotes new energy, and the lithium battery industry has also developed greatly. At present, lithium batteries have the advantages of high voltage, high energy, many cycles, and long storage time. They have been widely used in large and medium-sized electric equipment and automobiles. In the current equipment production of cylindrical lithium batteries, the requirements for the battery appearance inspection process are not only to inspect the two end faces of the cylinder, but also to inspect the cylindrical surface of the cylinder. Due to the different inspection requirements and inspection areas of the two inspection positions of the cylindrical battery, the cylindrical surface inspection speed is slower than the two end surface inspection speed. When performing end face inspection on cylindrical batteries, it is necessary to group the batteries that have been inspected by the cylindrical surface on multiple paths to avoid line congestion or long waiting time for equipment. Under the background of manufacturing automation, it is imperative to achieve automation while controlling equipment costs and improving the overall system beat of the equipment.
