[0002] Lithium batteries are an indispensable power source in daily life and industrial production, and the demand is very large. In addition, in the production process of lithium batteries, after the battery cover is produced, it is generally engraved on the top surface of the battery cover by laser engraving or other methods to ensure that the battery cover has a mark that can be scanned and identified.

[0003] At present, in the process of coding and welding of the battery top cover, the existing lithium battery processing production line usually adopts a segmented processing operation to process the battery top cover, that is: first, the battery top cover is uniformly placed on the jig at the coding station for coding processing operation, and then after the coding processing is completed, the battery top cover after coding is taken out from the jig at the coding station by using a handling tool such as a handling robot, and then the battery top cover is flipped at a certain angle, and finally the battery top cover is placed in the jig at the welding station for subsequent welding operations.

[0004] Therefore, when using the existing lithium battery processing production line to produce and transport battery top covers, since it is necessary to transfer the battery top covers between fixtures at different processing stations, there will be a problem of low continuity, which will lead to a decrease in the overall production efficiency and production rhythm; at the same time, during the transportation process of the battery top cover, it is also easy to cause damage to the battery top cover, and the battery top cover processing accuracy is easily reduced due to multiple positioning actions.
