Automatic Battery Electrode Sheet Die Cutting Forming Machine

Product Overview

This automatic battery electrode sheet die cutting forming machine is designed for continuous roll-to-sheet die cutting and forming of lithium battery electrode materials. The system combines controlled unwinding, tension stabilization, precision web alignment, servo-driven feeding, high-speed die cutting, edge-trim collection, and automatic finished-sheet discharge in one integrated production line. Its coordinated motion architecture supports repeatable electrode dimensions and efficient material handling.

The equipment is suitable for lithium battery electrode production, pilot-line development, laboratory-scale manufacturing, and advanced materials research. It processes incoming electrode rolls with widths up to 300 mm, roll diameters up to 400 mm, and material thicknesses from 20 to 180 µm. A qualified output rate of at least 98% supports dependable production planning and reduces material losses during repeated batch processing.

A rigid painted square-tube frame, cast die-cutting base, plated metal components, aluminum alloy structures, servo motion control, and pneumatic clamping elements provide a robust foundation for demanding operation. Closed-loop correction, controlled feeding, and adjustable die-cutting platform movement help maintain stable performance when processing thin, sensitive electrode materials.

Key Features

• Automatic Roll-to-Sheet Processing: The system automatically unwinds electrode roll stock, guides the material through tension and alignment stages, performs die cutting, collects edge trim, and transfers finished electrodes into a receiving tray. This reduces manual handling and supports a consistent production rhythm.

• Intelligent Variable-Speed Unwinding: A variable-frequency motor and position-detection potentiometer coordinate unwinding speed with the production process. The controlled feed helps prevent excessive slack, material pulling, and unstable roll movement.

• Stable Web Tension Control: A floating roller mechanism maintains suitable electrode tension throughout material transport. Stable tension helps protect coated surfaces and supports dimensional consistency during high-frequency cutting.

• Closed-Loop Precision Correction: A servo correction mechanism works with alignment sensors to provide high-precision closed-loop web positioning. This arrangement compensates for lateral deviation before the electrode enters the cutting station.

• Servo-Driven Precision Feeding: The feed rollers use nitrile rubber surfaces and are driven by a servo motor with a precision planetary reducer. The combination provides controlled, repeatable feeding for accurate electrode placement and reliable step movement.

• High-Speed Single-Station Die Cutting: A dedicated high-speed die-cutting station is configured to improve throughput while maintaining controlled material positioning. The production rate reaches 30–40 cuts per minute under suitable operating conditions.

• Programmable PLC and Touchscreen Control: PLC-based operation allows the operator to set step precision and the required die-cutting quantity. The touchscreen also provides manual adjustment of the lower die-cutting platform, simplifying setup and process changes.

• Adjustable Die Platform Movement: A stepper motor controls the vertical movement of the lower die-cutting platform. Each upward or downward step displacement can be adjusted through the touchscreen for controlled setup and repeatable operation.

• Smooth Edge-Trim Collection: The pull-belt scrap collection mechanism transports edge trim smoothly and continuously. The design helps reduce scrap interruption and prevents edge material from breaking during collection.

• Industrial Structural Design: The machine incorporates a painted square-tube main frame, hardened aluminum rollers with brown surface treatment, plated metal rollers, aluminum alloy side panels, and a cast die-cutting base. These construction details support long-term mechanical stability and repeatable alignment.
