Description

ATOMFAIR CSWM-8632 CYLINDRICAL SEMI-AUTOMATIC WINDING MACHINE

RESEARCH GRADE EQUIPMENT

Product Overview
The ATOMFAIR CSWM-8632 Cylindrical Battery Winding Machine is a semi-automatic precision winding system designed for lithium-ion cell precision winding in research and production environments. Featuring a single-needle automatic taping 2-35mm opposite-penetration winding needle structure, the machine delivers high winding stability with manual electrode feeding and automatic winding, needle changing, termination tape application, and cell discharging. The system achieves ±0.5mm alignment dual tension control through dual active separator unwinding with tension proximity switch regulation—tension is automatically and smoothly adjusted during winding with independent upper and lower tension control. Termination tape is applied transversely for flat, precisely positioned application without stretching the cell. Supporting separator outer-wrap finishing, the machine accommodates electrode widths of 28–73 mm, separator widths of 30–75 mm, and winding needle diameters from 1.8 to 6.0 mm, producing finished cells with outer diameters from 6 mm to 35 mm at a capacity of 5–10 pcs/min. The V2.0 design delivers a qualification rate ≥98% with user-friendly specification adjustment and rapid changeover.

Key Features & Advantages
  • Single-Needle Opposite-Penetration Winding Structure: The precision-engineered winding mechanism delivers high winding stability with the single-needle opposite-penetration design, ensuring consistent core formation and reliable cell quality across production batches.
  • Automatic Taping with Transverse Application: Termination tape is applied transversely (perpendicular to tabs) for flat and precisely positioned application without stretching the cell, delivering stable and reliable taping results.
  • Independent Dual Tension Control System: Dual active separator unwinding with tension proximity switch control provides automatically and smoothly adjusted tension during winding, with independent upper and lower tension regulation to ensure optimal winding quality.
  • ±0.5 mm Comprehensive Alignment Precision: The machine achieves separator alignment error ≤ ±0.5 mm, electrode alignment error ≤ ±0.5 mm, and finished cell cross-section alignment ≤ ±0.5 mm, with a qualification rate ≥98% under qualified material conditions.

APPLICATION SCOPE: Precision winding of cylindrical lithium-ion battery cells for research and pilot production. Suitable for positive and negative electrode materials interleaved with separator according to process requirements. Supports negative electrode wrapping positive electrode and separator wrapping negative electrode configurations. Compatible with electrode lengths from 150–1000 mm, widths from 28–73 mm, and finished cell outer diameters from 6 mm to 35 mm.
PACKAGING & DELIVERY: Each CSWM-8632 winding machine is securely packed for industrial equipment transport. Standard configuration includes the winding unit with single-needle mechanism, automatic taping system, dual separator unwinding stations with tension control, and operator interface. Installation guidance and operational training support are provided upon request.
IMPORTANT NOTICE: The qualification rate ≥98% is specified under qualified material conditions and excludes non-equipment factors. Winding needle diameters are customizable to customer requirements. Actual production capacity (5–10 pcs/min) varies based on electrode length and width parameters.
