High-safety pressure-relief explosion-proof type puncture detection device for production, research and development of pouch lithium battery cell

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.

Description

technical field [0001] The invention relates to the technical field of production and research of soft-packed lithium batteries, in particular to a high-safety pressure-relieving and explosion-proof puncture detection device for the production and research of soft-packed lithium batteries. Background technique [0002] With the gradual development of new energy technology, people's demand for lithium batteries has also increased rapidly. At the same time, the production quality and safety of lithium batteries have attracted more attention. Therefore, during the production and development of soft-pack lithium batteries, it is necessary to use testing However, there are still some deficiencies in the existing puncture detection devices for the production and development of soft-packed lithium batteries; [0003] For example, a lithium battery puncture and shear experiment device with a publication number of CN112763913A, which punctures the battery with a sharp object, detects...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a high-safety pressure relief and explosion-proof puncture detection device for the production and development of soft-packed lithium batteries, so as to solve the problem that the puncture detection devices for the production and development of soft-packed lithium batteries on the market cannot be quickly detected by the above-mentioned background technology. The smoke is effectively sucked, causing the smoke to diffuse or leak, which will affect the observation of the puncture process by the technicians. At the same time, it is inconvenient to automatically prevent explosion and fire extinguishing of the punctured battery, which leads to safety hazards during the experiment.
