Products Description
The machine is designed for precision winding of cylindrical battery cores. Its operational process involves manually guiding the cathode and anode electrodes into the winding section, where they are separated and stacked with a separator. The winding process adheres to specific process requirements, automatically applying termination tape and feeding the cell.
Key Functions and Features:
- Single Needle Counterwinding Structure: Utilizes a single needle counterwinding mechanism for precise winding.
- Automated Operations: Features manual electrode lead-in with automated winding, needle changing, tape ending, and unloading.
- Horizontal Tape Application: Employs horizontal tape pasting (tape perpendicular to the tab) ensuring flat and accurate adhesive placement without tightening the cell, providing stable and reliable adhesion.
- Adjustable Winding Speed: Offers adjustable winding needle speed for flexibility in operation.
- Separator Tension Control: Incorporates two rolls of separator with active unwinding and tension push switch control technology, allowing automatic tension adjustment during winding.
- Dust Removal: Equipped with a dust removal device to maintain cleanliness.
- Separator Outer Pack End: Ensures the separator is neatly packed at the end.
- Damage-Free Winding: Guarantees that the wound cell is free from damage, core pulling, and electrode dislocation.
- User-Friendly Design: Easy to operate, adjust, and replace components, enhancing usability and maintenance efficiency.
This machine combines precision, automation, and user-friendly features to ensure high-quality winding of cylindrical battery cores.
