Abstract

The invention relates to an anti-imprint pressure resistance detection mechanism for automatic production of a lithium battery. The pressure resistance detection mechanism comprises a protection device, a detection eyepiece, a connecting sleeve shaft and a collection mechanism, the detection eyepiece is arranged at the left end of the exterior of the protection device; the connecting sleeve shaft is mounted at the bottom of the detection eyepiece; and the collection mechanism is mounted in the outside of the bottom of the connecting sleeve shaft. The anti-imprint pressure resistance detection mechanism in the automatic production of the lithium battery has the beneficial effects that through design of the protection device, when the pressure resistance detection is performed on the lithium battery, in order to avoid the problem of potential safety hazards when the lithium battery is exploded under pressure, a middle frame, the protection device and the auxiliary frame can be used for designing a middle frame superposition structure, so that the impact resistance of the protection device can be improved when the explosion occurs; and after the lithium battery detection mechanism is used, the whole detection mechanism can be shielded and protected by utilizing the interaction among the protection device, the middle frame and the auxiliary frame.

Description

technical field

[0001] The invention relates to the technical field of automatic production of lithium batteries, in particular to a pressure resistance detection mechanism for automatic production of lithium batteries to prevent embossing. Background technique

[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses non-aqueous electrolyte solution. Lithium metal battery was first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S.Whittingham proposed and Began to study lithium-ion batteries, and tested their pressure resistance during the production process of lithium batteries.

[0003] The pressure resistance detection mechanism used in the automatic production of lithium batteries does not have a good protective effect during use, and the problem of shielding and protecting the entire detection mechanism when the detection mechanism is not needed. In addition, it is inco...
