Application Of High Power Ultrasonic Transducer Converter

Ultrasonic transducers are widely used. They are divided into industry, agriculture, transportation, life, medical and military according to the applied industry. According to the functions realized, 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 liquid, gas, biological, etc.; according to the nature, it is divided into power ultrasonic, ultrasonic detection, ultrasonic imaging, etc. .

  Piezoelectric ceramic transformer

  Piezoelectric ceramic transformers use the piezoelectric effect of the piezoelectric body after polarization to achieve voltage output. The input part is driven by a sinusoidal voltage signal, which is vibrated by the inverse piezoelectric effect. The vibration wave is mechanically coupled to the output part through the input and output parts, and the output part generates electric charge through the positive piezoelectric effect to realize the electric energy of the piezoelectric body. - Mechanical energy - two transformations of electrical energy to obtain the highest output voltage at the resonant frequency of the piezoelectric transformer. Compared with the electromagnetic transformer, this has the advantages of small volume, light weight, high power density, high efficiency, breakdown resistance, high temperature resistance, no fear of burning, no electromagnetic interference and electromagnetic noise, and simple structure, easy production, and easy mass production. Some areas have become an ideal replacement for electromagnetic transformers. Such transformers are used in switching converters, notebook computers, xenon lamp drivers, and the like.

  Ultrasonic welding

  Ultrasonic welding has two major categories: ultrasonic metal welding and ultrasonic plastic welding. Among them, ultrasonic plastic welding technology has been widely used. It uses ultrasonic vibration generated by the transducer to transmit ultrasonic vibration energy to the weld zone through the upper weldment. Since the welding zone, that is, the sound resistance at the junction of the two weldments is large, local high temperature is generated to melt the plastic, and the welding work is completed under the contact pressure. Ultrasonic plastic welding facilitates the welding of parts that cannot be welded by other welding methods. In addition, it also saves expensive mold costs for plastic products, shortens processing time, improves production efficiency, and is economical, fast and reliable.

  Ultrasonic machining

  The fine abrasive is applied to the workpiece with a certain static pressure along with the ultrasonic processing tool, and the same shape as the tool can be processed. The transducer needs to generate an amplitude of 15 to 40 microns at a frequency of 15 to 40 kHz during processing. The ultrasonic tool continuously impacts the abrasive on the surface of the workpiece with a considerable impact force, destroying the ultrasonic radiation portion, and breaking the material to achieve the purpose of removing the material. Ultrasonic processing is mainly applied to the processing of brittle and hard materials such as gemstones, jade, marble, agate, and hard alloy, as well as the processing of shaped holes and deep holes. In addition, when the ultrasonic transducer is vibrated on a common cutting tool, it can also improve the accuracy and efficiency.
