Fully Automatic Supercapacitor Electrode Separator Winding Machine

Product Overview

This fully automatic supercapacitor winding machine is designed to assemble positive electrode sheets, negative electrode sheets, separators, termination tape, and protective tape into precisely wound electrode groups. Operators manually load the material rolls and tapes, after which the equipment completes the defined winding sequence automatically according to established product and process requirements. Integrated length detection, tension control, alignment correction, short circuit testing, and quality classification support a controlled and repeatable production process.

The equipment is suitable for supercapacitor electrode group fabrication in battery and energy storage laboratories, pilot production lines, advanced materials research centers, and manufacturing environments requiring consistent winding quality. Its stable operating condition and process assurance make it appropriate for repeated development runs, production validation, and demanding process-control applications where material alignment, dimensional consistency, and electrical integrity directly influence downstream cell performance.

Key Features

• Automatic Electrode Group Winding: After manual loading of the positive electrode, negative electrode, separator, termination tape, and protective tape, the system completes the programmed winding operation automatically for consistent electrode group formation.

• Integrated Process Sequence: The equipment combines separator feeding, termination and protective tape feeding, electrode feeding, foil connection-tape inspection, winding, length control, tape application, short circuit testing, and good-product classification in one coordinated workflow.

• Controlled Material Tension: Automatic tension control helps maintain stable material handling throughout winding. This supports uniform layer placement and reduces process variation caused by inconsistent web tension.

• Automatic Alignment Correction: Automatic deviation correction keeps electrodes and separators correctly positioned during operation. Stable alignment is essential for repeatable electrode group geometry and dependable downstream assembly.

• Length Detection and Control: Length detection verifies the winding material and supports controlled electrode group dimensions. This enables production according to predefined product specifications and process requirements.

• Electrical Integrity Testing: Built-in short circuit testing checks completed wound groups before classification. Early detection helps prevent defective units from progressing to subsequent assembly or testing operations.

• Automated Quality Classification: The unit distinguishes qualified products after inspection and testing, supporting more efficient handling and clearer separation of acceptable and potentially defective electrode groups.

• Stable Industrial Construction: The equipment is engineered for reliable operation under defined laboratory and production-site conditions. Its 3,000 kg structure and enclosed footprint provide a substantial platform for repeatable winding performance.

• Wide Material Compatibility: The feeding system accommodates positive and negative electrode rolls with lengths from 600 to 6000 mm, widths from 80 to 160 mm, and thicknesses from 100 to 320 μm, while the separator system supports widths from 80 to 160 mm and thicknesses from 16 to 50 μm.
