AI Technical Summary

Technical Problem

In the lithium battery production process, there is a problem of incomplete dust removal during the electrode sheet transport process, especially in the area blocked by the through holes of the vacuum adsorption conveyor belt, where dust is difficult to remove.

Method used

Two conveyor belts are driven by independent power systems. Combining the principles of negative pressure device and vacuum adsorption, dust removal is achieved on the surface of the electrode sheet through synchronous and opposite transmission actions, in conjunction with the opening and closing of the negative pressure device.

Benefits of technology

It effectively removes dust from the surface of the electrode sheet, ensuring the stability and dust removal effect of the electrode sheet during transmission, and achieving stable transmission and efficient dust removal of the electrode sheet.

Abstract

This invention discloses an integrated electrode sheet conveying and dust removal device and its production process based on vacuum adsorption. The device includes: a conveying support frame, a dust collection and support integrated box, a first conveyor belt, a second conveyor belt, a negative pressure device, a material unloading stack, and a material unloading and transfer device. The conveying support frame includes a left-side conveying support bar and a right-side conveying support bar, and the dust collection and support integrated box is located within an accommodating space. The first and second conveyor belts are arranged side-by-side and surround the beginning and end of the conveying support frame, and are independently driven by two separate power transmission systems. The first and second conveyor belts have through holes, and the dust collection and support integrated box has negative pressure through holes. The negative pressure device provides negative pressure to the dust collection and support integrated box. The material unloading and transfer device transfers the electrode sheets to the material unloading stack. Both during the electrode sheet conveying process and during the electrode sheet dust removal process, the vacuum adsorption principle is utilized, effectively removing dust from the electrode sheet surface.
