Abstract

[0002] An ultrasonic welding machine generates high-voltage and high-frequency signals of 20KHz (or 15KHz) by a generator. Through a transducer system, the signals are converted into high-frequency mechanical vibrations and applied to the workpiece. The temperature at the interface is increased by the friction between the workpiece surfaces and between molecules. When the temperature reaches the melting point of the workpiece itself, the interfaces of the workpiece are quickly melted, and then the voids between the interfaces are filled. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time, thus achieving high-quality welding.
[0003] However, the welding head of the existing ultrasonic welding machine moves up and down to weld the workpiece below, so it can only weld a specific part of the workpiece with a fixed position and cannot weld multiple points of the workpiece. Summary of the Utility Model
