AI Technical Summary

⚠Technical Problem

Existing soft-pack lithium battery rolling devices lack sufficient precision in controlling rolling pressure, which can easily cause permanent damage to the battery, and also lack effective buffer protection.

⚗Method used

The soft-pack lithium battery rolling mechanism uses pressure sensor feedback for pressure regulation. It drives the rolling roller assembly to move synchronously by driving a servo motor, and uses a pressure regulating buffer assembly composed of a pressure sensor and a buffer cylinder to adjust the rolling pressure in real time to avoid damage to the battery due to excessive pressure.

🎯Benefits of technology

It achieves high-precision and stable rolling pressure control, avoids battery damage, improves rolling efficiency and battery performance, and reduces product scrap rate.

Abstract

The application discloses a soft package lithium battery rolling mechanism for pressure adjustment through pressure sensor feedback, which comprises a bottom plate, a left rolling wheel assembly, a right rolling wheel assembly, a driving assembly and a pressure adjustment buffer assembly; the driving assembly comprises a driving servo motor, a positive and negative toothed ball screw and a first linear guide rail; the pressure adjustment buffer assembly comprises a buffer air cylinder, a pressure sensor and a second linear guide rail. The driving servo motor drives the positive and negative toothed ball screw to rotate to control the left rolling wheel assembly and the right rolling wheel assembly to approach or move away from the center at the same speed. When the extrusion force on the soft package lithium battery is too large, the pressure sensor feeds back, and the buffer air cylinder drives the left rolling wheel assembly to move left to prevent the soft package lithium battery from being damaged. The application has the advantages of compact and ingenious structure, accurate and stable rolling force control, pressure feedback adjustment function, permanent damage to the battery during rolling can be avoided, and the product scrap rate is reduced.
