[0003] The utility model of the notification number CN211554204U discloses a power battery detection integrated device, which can realize the coordinated operation requirements of helium detection and electric detection on the same platform. Helium detection and electric detection belong to the rigid detection items of the power battery cover plate. Separate testing is required, first of all, air tightness testing needs to be re-inspected, on the one hand to ensure the pass rate of the test, on the other hand, it can effectively prevent the occurrence of false detections and lead to the scrapping of qualified products, and the electrical inspection does not require re-inspection, and can be marked or even online after the test Destruction and scrapping, so if the two tests are collinear, it is easy to affect the quality of the test

Secondly, there are multiple NG classifications in helium detection and electrical detection, and collinear detection will cause difficulties in NG classification.

Finally, there will be a large number of detection stations allocated, and the space occupied by the shared platform will be very large. At the same time, the probability of station failure and downtime will increase significantly and maintenance will be more difficult.

[0004] The Chinese invention patent with the notification number CN206561971U discloses a power battery cover plate automatic detection and lamination machine, which realizes the position index switching by rotating the tray, so as to meet the detection functions of electrical inspection, flatness detection, and film lamination. The work positions of the tray are limited, so it is difficult to realize the refinement of various work positions. At the same time, in order to cooperate with each work position, each electric inspection seat, film sticking mechanism, and flatness detection mechanism need to be designed to be small and compact, and it is difficult to ensure that each work position The structural strength and service life of the mechanism, in addition, the film sticking station needs to frequently replace the film material roll, which is likely to affect the continuity and efficiency of the detection. Higher, it is easy to cause the film to be biased and affect the product qualification rate

It should also be noted that poor electrical inspection of the battery cover will pose a greater risk for subsequent battery assembly, so it is necessary to design a destruction station to prevent such NG products from being used to assemble finished batteries, and the turnover line of the rotary tray type cannot meet the requirements. The need for station expansion affects automated testing

[0005] The electric inspection of the battery cover also needs to be organically combined with the front-end air tightness inspection production line, so as to meet the needs of interconnection and flow-water docking. However, there is a difference in efficiency in the automated production line, and the front-end feeding speed will have a greater impact on the subsequent automatic inspection. At the same time, front-end conveying products generally have differences in forward and reverse supply, so there are many requirements for online capacity control and feed alignment adjustment of automated testing equipment, while traditional equipment is not enough to meet the needs of automated docking and flow.
