Abstract

The invention discloses a high-safety pressure-relief explosion-proof type puncture detection device for production, research and development of a pouch lithium battery cell. The high-safety pressure-relief explosion-proof type puncture detection device comprises a control base and a hydraulic rod, and further comprises a movable cylinder, a gear, two groups of movable boxes, an adjusting ring and a fan, wherein the control base is placed above a working table, the hydraulic rod is fixedly mounted on the outer side of the upper end of a fireproof cover, the movable cylinder is connected to the lower end of the hydraulic rod through a bearing, the gear is connected to the interior of a fireproof base through a shaft, the two groups of movable boxes are symmetrically and movably mounted on the upper surface of the fireproof base, the adjusting ring sleeves the outer side of the movable cylinder, and the fan is mounted at the upper end of the fireproof cover. The high-safety pressure-relief explosion-proof type puncture detection device for production, research and development of the pouch lithium battery cell has the advantages that the lithium battery cell can automatically be buffered and clamped in the puncture process, in addition, fire extinguishment and protection can be automatically carried out when the battery cell swells or explodes, fire spreading and further explosion can be avoided, the use safety is high, and meanwhile, a smoke hood can be driven to carry out large-range efficient smoke removal by utilizing smoke ejected at a high speed in the puncture process.
