28khz/35khz/40khz ultrasonic spot welder machine

Ultrasonic spot welder machine is divided into: ultrasonic spot welding machine, ultrasonic plastic spot welding machine, riveting point welding machine, ultrasonic metal welding machine, ultrasonic metal spot welding machine, ultrasonic welding machine, aluminum nickel welding machine, polymer battery positive pole welding machine, lithium battery negative pole welding machine, aluminum to nickel spot welding machine, amorphous silicon spot welding machine, etc.

 

The welding principle of ultrasonic spot welding machine is to convert 50 / 60 Hz current into 15, 20, 30 or 40 kHz electric energy through ultrasonic generator. The converted high-frequency electric energy is converted into the mechanical motion of the same frequency again through the transducer, and then the mechanical movement is transmitted to the welding head through a set of amplitude modulator device which can change the amplitude. The vibration energy received by the welding head is transferred to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction, and the plastic is melted. After the vibration stops, the short-term pressure maintained on the workpiece makes the two weldments solidify in the form of molecular link. Generally, the welding time is less than 1 second, and the welding strength obtained is comparable to that of the body. Ultrasonic can be used not only to weld hard thermoplastic plastics, but also to process fabrics and films. The main components of an ultrasonic welding system include ultrasonic generator, transducer / amplitude modulator / welding head, mould and frame.
