AI Technical Summary

Technical Problem

The existing lithium battery production standard machine lacks a limiting mechanism, which results in the downforce of the lifting cylinder being uncontrolled when performing the label compaction operation, which easily leads to damage to the battery pack.

Method used

A lithium battery rolling mechanism is designed, including a mounting frame, a pressure-retaining cylinder, a limiter and a rolling assembly. The limiter provides support to the rolling assembly to prevent the output end of the pressure-retaining cylinder from sagging when it is not working, and prevent damage to components caused by excessive internal air pressure.

Benefits of technology

By setting up a limiter, ensure that the rolling assembly is supported when it is not working, avoid excessive air pressure inside the pressure-holding cylinder, extend the service life of the equipment, and prevent damage to the battery pack.

Abstract

The present invention relates to the technical field of lithium battery rolling equipment, and in particular to a lithium battery rolling mechanism and a precise pressure control system thereof, comprising: a mounting frame, a pressure-maintaining cylinder, a limiter and a rolling assembly, wherein the mounting frame is mounted on a conveyor belt mechanism, and the output end of the pressure-maintaining cylinder on the mounting frame is connected to the rolling assembly, the rolling assembly is arranged toward the conveyor belt mechanism, and the side of the rolling assembly contacts and cooperates with the top of the limiter, the limiter is threadedly connected to the mounting frame, and the limiter is specifically cylindrical. By setting the limiter, support can be provided to the rolling assembly when the device is not working, thereby supporting the output end of the pressure-maintaining cylinder, thereby preventing the output end of the pressure-maintaining cylinder from sagging under the action of gravity so that the residual gas therein exerts pressure on the inside of the pressure-maintaining cylinder, thereby preventing damage to components caused by excessive internal air pressure of the pressure-maintaining cylinder when the pressure-maintaining cylinder is not working.
