1. Scalable Parallel Arrangement

The product adopts parallel arrangement, which can realize the whole line reconfigurable production capacity, therefore the equipment upgrade and

process route adjustment can be carried out conveniently. This arrangement boasts high scalability, which can support the efficiency upgrade by

combining magnetic levitation, and some other conveying technologies.

2. Versatile Compatibility and Precision Conveying

The product is compatible with kneading / cutting and bending tabless forming process.The main process of product adopts flexible cam conveying

method and horizontal intermittent conveying mode for the cell, which can avoid dust dropping due to gravity, and ending surface deforming by

extrusion, and maintain high positioning accuracy and high flexibility.

3. Advanced Laser Welding Sealing Process

It adopts laser welding sealing process, which welds positive and negative electrode cover panel to the can by laser, and seals it. Through wobble 

welding and real time compensation technology for welding focal length, it realizes the dynamic balanced welding under the condition that multiple

workstation rotate with high speed, resulting in high welding efficiency. The sealing performance can pass 1*10-13 Pa·m3 accuracy helium inspection

test, and the cell utilization rate is high,which is conductive to increase single cell’s power density.

4. Efficient Tooling Fixture and Flexible Production Control

The number of product tooling fixture is rather small, and it adopts flexible production capability+full digital control, which is conductive for continues

optimization, meanwhile the production line has high tolerance for the consistency difference for work piece, with high production qualification rate.
