1. Dual-Actuator Hot Pressing

The hot pressing process adopts a dual-actuator design, ensuring high efficiency and precision. The surface of the hot pressing plate is coated with a ceramic composite 

and equipped with vacuum breaking technology to prevent pole sticking.


2. Flexible Tab Welding

The tab welding process employs a floating pressure mechanism for flexible clamping, preventing damage to the cover. The welding protection plate supports automatic 

replacement and utilizes circular spot welding with diverse trajectories, ensuring stable and reliable welding quality.


3. Real-Time Shell Insertion Monitoring

Real-time monitoring, automatic adjustment, calibration, and recording of shell insertion pressure prevent overpressure, rebound, and damage to workpieces. A fully sealed 

dust removal chamber is employed to safeguard shell insertion quality from all angles.


4. Cover Welding with Autonomous Protection

The cover welding is equipped with a welding protection device featuring autonomous replacement functionality. Welding parameters are automatically measured and 

calibrated. A turbo-type dust suction device and circular spot welding ensure efficient and high-quality welding.


5. Pulse Laser Seal Pin Welding

Seal pin welding utilizes a self-developed pulse laser with stable output power. Seal pins do not deform during spot welding and full welding processes. Real-time monitoring 

of coaxial dust removal and 3D visual inspection functions are implemented to ensure welding quality.
