Abstract
The utility model relates to the technical field of lithium ion battery manufacturing and especially relates to a leakage detection device for an anti-explosion valve of a lithium-ion power battery. The leakage detection device comprises an anti-explosion valve positioning mechanism and an anti-explosion valve sealing mechanism. A toggle clamp in the anti-explosion valve sealing mechanism is convenient and rapid to operate and firm in tight compaction, and matches a sealing ring in use to enable sealed space to be tight. A sealing head and a sealing press ring are pressed at two sides of a weld joint of the anti-explosion valve, so that sealed space is formed, and a targeted leakage detection on the weld joint of the anti-explosion valve can be carried out. As a result, a battery cover of poor sealing properties is prevented from flowing into a subsequence procedure, and a battery is prevented from being scrapped because the anti-explosion valve leaks liquid.
