AI Technical Summary

Technical Problem

Existing lithium battery separator heat treatment equipment cannot flexibly adjust its structure during transportation, resulting in insufficient separator tension and affecting the heat treatment effect.

Method used

The design incorporates an adjustable roller frame and an exhaust assembly, utilizing a servo motor to drive a bidirectional lead screw and an electric telescopic rod to achieve flexible adjustment of the moving roller and tension roller. Combined with the bellows structure of the exhaust pipe, it ensures the flatness of the diaphragm and the uniformity of hot air.

Benefits of technology

This effectively ensures the structural stability and heat treatment effect of the lithium battery separator during the heat treatment process, avoids separator displacement and wrinkles, and improves the uniformity and efficiency of heat treatment.

Abstract

This utility model discloses a lithium battery separator heat treatment device, relating to the field of lithium battery separator heat treatment technology. It includes a heat treatment chamber and an adjusting roller frame. The adjusting roller frame is horizontally mounted at the lower end of the heat treatment chamber, and an auxiliary roller frame is horizontally mounted in the middle of the adjusting roller frame. An exhaust assembly is mounted directly above the auxiliary roller frame. This lithium battery separator heat treatment device, by providing an adjusting roller frame at the lower end of the heat treatment chamber, allows for appropriate adjustment of the relative distance between symmetrically arranged moving rollers within a certain range. Simultaneously, the structural mobility of the auxiliary roller frame in the middle allows for tensioning of the separator, thus regulating the stability of the material conveying and ensuring the flatness of the separator. Combined with the height-adjustable exhaust assembly, it enables flexible and effective heat treatment processing, thereby ensuring processing quality while maintaining the flexibility of the device structure.
