AI Technical Summary

Technical Problem

Existing battery electrode cutting dies have problems with low efficiency and incomplete dust cleaning, especially dust is difficult to be removed in a timely and effective manner, affecting mold operation and cutting quality.

Method used

An integrated dust removal device is designed. The dust removal box is close to the lower cutting knife. Multiple dust removal holes and dust collection slots are set near the cutting position. Combined with the dust removal fan, an efficient dust collection mechanism is formed to ensure that dust is quickly sucked into the dust removal system.

Benefits of technology

It improves the efficiency and thoroughness of dust cleaning, reduces the chance of dust escaping, ensures the stability and production efficiency of the cutting process, and reduces the need for manual cleaning.

Abstract

The present application provides a battery electrode cutting die, comprising an upper die, a lower die, a cutting blade assembly, a support assembly, and a dust removal device. The dust removal device comprises a dust removal box, which is mounted on the support assembly. The first side surface of the lower cutting blade is provided with multiple rows of dust through holes, which communicate with a dust collection chamber within the dust removal box. A hanging platform is provided on the first side surface, and a dust collection trough is formed between the hanging platform and the first side surface of the dust removal box. The upper end of the dust collection trough is a material collection opening, which corresponds to a dust collection gap. Dust generated after the upper and lower cutting blades cut the battery electrode enters the dust collection trough from the material collection opening through the dust collection gap. An integrated high-efficiency dust removal device is provided. The dust collection box is tightly attached to the lower cutting blade, minimizing the dust escape path. Multiple rows of through holes in the box connect to the dust collection chamber, and combined with the dust collection trough enclosed by the hanging platform, an efficient collection mechanism is formed. The cut dust enters the trough through the dust collection gap and is then forcefully sucked in by the dust removal fan to ensure complete removal.
