Abstract

The invention discloses an air tightness detection device and an air tightness detection method. The air tightness detection device provides special equipment for detecting the air tightness of a battery pack PACK upper cover, a workpiece sealing mold is arranged to form a sealable cavity with the battery pack PACK upper cover, and the position precision of the workpiece sealing mold is ensured through a positioning structure. An edge sealing mechanism and an anti-deformation mechanism are combined to guarantee the sealing performance and prevent the battery pack PACK upper cover from deforming during detection, so that reliable conditions are created for airtightness detection, airtightness detection of the battery pack PACK upper cover can be effectively carried out, and a basic guarantee is provided for improving the airtightness of the battery pack.
