A high-safety pressure-relief explosion-proof puncture detection device for the production and development of soft-packed lithium batteries

Abstract

The invention discloses a high-safety pressure-relief explosion-proof puncture detection device for the production and development of soft-packed lithium batteries, which comprises a control seat placed above a work table; a hydraulic rod is fixedly installed on the outer side of the upper end of the fireproof cover; It also includes a movable cylinder, the bearing is connected to the lower end of the hydraulic rod; the gear, the shaft is connected to the inside of the fireproof seat; two sets of movable boxes are symmetrically installed on the upper surface of the fireproof seat; The outer side of the movable cylinder; the fan is installed on the upper end of the fireproof cover. The high-safety pressure-relief explosion-proof puncture detection device for the production and development of soft-packed lithium batteries can automatically buffer and clamp the lithium batteries during the puncture process, and can automatically extinguish and protect the batteries when the batteries expand or explode. To avoid fire spread and further explosion, it is safe to use, and at the same time, the smoke hood can be driven by the high-speed ejected smoke during the puncture process to carry out large-scale and high-efficiency smoke removal.

Description

technical field [0001] The invention relates to the technical field of production, research and development of soft-packed lithium batteries, in particular to a pressure-relief explosion-proof puncture detection device for the production and development of soft-packed lithium batteries with high safety. Background technique [0002] With the gradual development of new energy technology, people's demand for lithium batteries has also increased rapidly, and the production quality and use safety of lithium batteries have also attracted more attention. Therefore, in the production and development process of soft-pack lithium batteries, it is necessary to use testing The device performs puncture experiments on it, but the existing puncture detection devices for the production and development of soft-pack lithium batteries still have some shortcomings; [0003] For example, a lithium battery puncturing and shearing experimental device with the publication number of CN112763913A, w...

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.
