Principle of ultrasonic welding machine: The ultrasonic welding machine uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form fusion between the molecular layers. Composition of ultrasonic welding machine: The ultrasonic welding machine is mainly composed of the following parts: generator, pneumatic part, program control part, and transducer part. The main function of the generator is to convert the power frequency of 50HZ into high-voltage waves of high frequency (such as 20KHZ) using electronic circuits. The main function of the pneumatic part is to complete the pressure work such as pressurization and pressure maintenance during the processing process. The program control part controls the workflow of the entire machine to achieve consistent processing results. The transducer part converts the high-voltage radio waves generated by the generator into mechanical vibrations, which are transmitted and amplified to reach the machined surface.
