Laser Notching and Slitting Machine

Product Overview

The machine integrates laser notching and slitting functions. It first cuts the uncoated foils into tabs at high speed, and then slits the wide electrode into narrow strips for subsequent processing.

Features

Small burrs, less heat affect, and higher notching quality;

High-speed laser notching control system, with a stable production speed of 120m/min (for tabs shorter than 25mm);

High-precision tandem roller transfer system, with a total length accuracy of ±1.5mm for 6m electrode, and ±3mm for 12m electrode, respectively;

Air knife, magnetic bar, brushes, negative pressure dedusting, FFU, and dust collector are configured to control dust and impurities, ensuring high production safety.

Standard Configuration

Unwinding unit: Air shaft unwinding, diameter measurement, unwinding correction, and splicing table;

Tension control unit: Tension roller, tension detection, and tension control system;

Tab notching unit: Correction, laser notching, and notching detection;

Main traction unit: Main roller, press roller, and servo control system;

Slitting unit: Slitting correction component and slitter;
