The ultrasonic transducer is a component that converts electrical energy into mechanical vibration and amplifies the amplitude, mainly including an ultrasonic transducer, ultrasonic horn, and ultrasonic welding head. The working principle of the ultrasonic transducer on the ultrasonic plastic welding machine is to use the inverse piezoelectric effect of the piezoelectric ceramic material to generate vibration.
A piezoelectric crystal is placed in an external electric field. Under the action of the electric field, the center of gravity of the positive and negative charges inside the crystal is moved, and this polarization displacement causes the crystal to deform. This is called the inverse piezoelectric effect.
Extended information:
Ultrasonic transducers are widely used, and they are divided into the industry, agriculture, transportation, life, medical care, and military according to the application industries. According to the realized functions, it is divided into ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, etc.; according to the working environment, it is divided into a liquid, gas, living body, etc.; according to its nature, it is divided into power ultrasonic, detection ultrasonic, ultrasonic imaging, etc.
