Abstract

The invention discloses power battery cover plate automatic helium detection equipment and a helium detection method, and the power battery cover plate automatic helium detection equipment comprises a battery cover plate supply device and a helium detection device. The battery cover plate supply device comprises a battery cover plate conveying line, a battery cover plate positioning mechanism and a battery cover plate turnover displacement mechanism; the helium detection device comprises a helium detection group, a temporary storage mechanism, an unloading part and a material turnover mechanism; the helium detection group comprises two helium detection initial detection mechanisms, a helium detection redetection mechanism and an initial detection and redetection switching detection mechanism, and the material turnover mechanism comprises a cover plate pickup part. The helium detection method comprises the steps of feeding, initial detection, redetection, classification and caching, and initial detection and redetection switching. According to the invention, primary inspection and reinspection can be carried out on the same platform, combination of multiple devices or unloading turnover is not needed, and the device cost and the transportation cost are reduced. And switching is carried out according to the condition of the material cached in the initial inspection, so that the initial inspection and the reinspection are coordinated and smoothly operated, and the helium inspection efficiency is remarkably improved.
