Supercapacitor Automatic Winding Machine Electrode Sheet Winder

Product Overview

This system is an industrial-grade, fully automated winding solution engineered specifically for high-capacity supercapacitors and advanced energy storage cells. Designed to integrate seamless manual material loading with intelligent, automated core processing, the equipment executes precision winding of positive electrodes, negative electrodes, and separator films under strict tension-regulated conditions. It automates critical downstream steps including lead and termination tape application, final outer protective wrapping, and real-time defect verification.

Built to satisfy the rigorous demands of pilot lines, energy research facilities, and high-yield commercial manufacturing plants, the equipment guarantees exceptional dimensional accuracy and uniform layer alignment. Its heavy-duty structural frame and high-precision drive mechanisms minimize mechanical vibration, ensuring repeatable layer-to-layer registration across long electrode lengths. Target industries include electric double-layer capacitor (EDLC) production, hybrid energy storage manufacturing, advanced automotive power systems, and academic battery materials research.

Engineered for continuous industrial duty, this unit features automated closed-loop tension regulation, photoelectric edge position correction, and inline short-circuit electrical testing. By combining meticulous mechanical guidance with comprehensive quality monitoring at every stage of the winding sequence, the machine eliminates internal cell defects, maximizes assembly throughput, and establishes unmatched operational consistency in mission-critical fabrication environments.

Key Features

• Precision Closed-Loop Tension Control: Advanced multi-axis servo drives and sensitive load-cell feedback continuously regulate web tension across cathode, anode, and separator reels, eliminating foil wrinkling, stretching, or micro-cracking during high-speed winding cycles.
• Integrated Web Guiding and Auto-Correction: Optical edge-detection sensors and dynamic alignment actuators correct feed path deviations in real time, guaranteeing exact edge-to-edge alignment tolerances of ±0.1 mm across the entire wound core structure.
• Automated Tape Application Subsystem: Precision-controlled pneumatic applicators automatically apply termination and protective outer wrapping tapes with exact placement and consistent bonding pressure, preventing core loosening during transfer.
• Inline Splicing and Foil Joint Detection: Built-in optical sensors inspect incoming electrode webs to detect foil splices or irregularities instantly, preventing defective material segments from being wound into finished cell assemblies.
• High-Voltage Short-Circuit Testing: Integrated dielectric and short-circuit testing modules evaluate the electrical insulation between anode and cathode layers immediately after winding, automatically sorting defective cores prior to downstream packaging.
• Programmable Core Length and Diameter Measurement: Digital optical encoders track electrode unwinding length in real time (up to 6000 mm per unit), ensuring exact turn counts, precise final outer diameters, and uniform volumetric capacitance.
• Heavy-Duty Rigid Gantry Frame: Constructed with a robust steel foundation and enclosed dust-protective canopy, the unit dampens high-frequency mechanical vibration and shields sensitive electrode webs from airborne particulates.
• Intuitive Touchscreen HMI and PLC Control: A full-color touchscreen interface facilitates simple recipe programming, real-time diagnostic telemetry, automated defect alarms, and comprehensive batch tracking for streamlined workflow integration.
