Product Introduction
Model：MR-20K
MR-20K 4200W Ultrasonic Metal Welding Machine is Designed for Lithium battery tab welding. It is designed for welding stacked electrode sheets (Copper & Aluminum) and tab onto current collectors to prepare Li-ion pouch cells in R&D laboratories and production line.
The 4500W battery welder can weld stacked electrode with 40-60 layers aluminum foil or copper foil with Al tab and Nickel tab.
The tab welding method is horizontal, and the welding surface life is ≥100,000 times;
Standard welding head, welding head material imported powder alloy, welding point height 0~50mm, upper welding head straight grain or rice grain, lower mold mesh. The height of the welding surface from the welding is adjustable from 0~50mm, and the welding head can have 2 welding surfaces.
The transducer can withstand a power of 4200W;
The built-in frequency of the ultrasonic generator is adjustable, the switching power supply is constant voltage and constant current (constant amplitude), and the amplitude is steplessly adjustable;
* Using advanced constant current and constant voltage circuit technology, the ultrasonic amplitude is continuously adjustable;
* Using intelligent ICS chassis control system with secondary ultrasonic function; the system starts self-checking, the vibration pair is intelligently segmented and automatically tracked.
* The mechanical structure of the machine head adopts the German X-rail structure with extremely high precision;
* Protection system:
⑴ Voltage protection system (power supply voltage range 220V~250V); the output power and working frequency of the machine are not affected during the automatic constant voltage;
⑵ Overload protection system;
⑶ Overcurrent protection;
⑷ Automatic compensation for unstable power supply frequency;
Welding overload protection signal feedback.
