Products Description
For more details about our advanced automatic battery electrode manufacturing machine, featuring tab welding and adhesive tape application, please don’t hesitate to contact us.
This state-of-the-art equipment is specifically designed for lithium-ion battery production, offering precision and efficiency in every step of the process.
Key Features and Operation:
- Material Handling and Processing:
- The slitted roll electrode is mounted on the equipment’s unwinding shaft.
- The process begins with tension control and material discharge, followed by precise deviation correction.
- The electrode is then guided over rollers to the ultrasonic welding section for tab welding.
- After welding, the electrode is pulled to a predetermined position where adhesive tape is automatically applied.
- The electrode passes through a dust suction device and a traction mechanism, culminating in the automatic winding of the finished electrode roll.
- Precision and Quality Control:
- The coating’s starting point on the electrode serves as the reference for precise tab welding.
- The system includes checks for successful tab welding and tape application.
- If any step is missed (e.g., welding or taping), the operator can manually intervene by triggering a switch to retract the electrode for necessary corrections.
- The machine ensures that each roll of electrode is uniformly processed, with tabs welded and protective tape applied, before the final roll is automatically collected.
This equipment is designed to enhance production efficiency while maintaining high standards of quality and reliability in lithium-ion battery manufacturing. Contact us to learn more about how this machine can benefit your production line.
