1.Efficient Linear Arrangement

The product adopts linear arrangement with small floor space, which highly utilize the site area, and it is convenient for production management and

equipment maintenance.


2.Versatile Compatibility with Forming Processes

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

and it also applies cell horizontal intermittent conveying, which can avoid the dust-dropping due to gravity, ending face deforming by extrusion, and

maintain high positioning accuracy and flexibility.


3.Versatile Compatibility with Forming Processes

It adopts laser welding sealing process, which uses laser to weld positive and negative electrode cover panel to can, and seal it also. 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.Optimized Tooling Fixture and Production Control

The product has a small number of tooling fixture, and it adopts flexible production capacity+full digital control, which is conducive to continuous process

optimization, meanwhile production line has a high tolerance for the consistency difference of work piece.
