Lithium battery cover plate helium detection leakage electrical performance of the film is mainly used in square and cylindrical lithium battery cover plate helium detection leakage electrical performance and film and other multi-functional integration equipment. The battery cover plate is entered into the device through the conveyor line or the material on the tray, and the data traceability system of the device automatically records the detection data of each cover plate, which can make statistics and query the production situation and qualification rate of the cover plate. The detection data can be exported and saved.
