The ultrasonic transducer is the "heart" of ultrasonic equipment. It is the basis for the generation of ultrasonic waves. It is a device that converts electrical energy into mechanical energy (ultrasound). The most mature and reliable device is the one that uses the piezoelectric effect to achieve the mutual conversion between electrical energy and sound energy, which is called a transducer.

So what are the application fields of ultrasonic transducers? Let's introduce its application fields to you below.

①Ultrasonic motor

Ultrasonic motors use the stator as a transducer, and use the inverse piezoelectric effect of piezoelectric crystals to make the motor stator vibrate at ultrasonic frequencies. The friction between the stator and the rotor is used to transfer energy and drive the rotor to rotate. Ultrasonic motors are beneficial to the miniaturization of devices and are widely used in the automotive field, intelligent robot field, electronic product field, medical device field, etc.

②Ultrasonic welding machine

Ultrasonic welding machine refers to equipment that processes and welds materials. The materials that can be welded include thermoplastics, metals and non-woven fabrics. Because ultrasonic welding machine is an energy-saving and efficient processing equipment and is widely used, it is used in many industries. Taking Shantou Ultrasonic Linggao ultrasonic welding machine as an example, ultrasonic welding machine can be widely used in the medical industry, auto parts industry, electronics industry, consumables communication industry, home appliance equipment industry, etc. The precision of Linggao ultrasonic welding machine can reach 0.01mm, which is very suitable for welding products with high parameter requirements.

③Ultrasonic cleaning machine

The ultrasonic cleaning machine consists of three parts: ultrasonic power supply, ultrasonic transducer and medium. It produces "cavitation effect" in the liquid under the action of high-frequency mechanical vibration propagation of tens of thousands of times per second. In other words, it uses ultrasonic energy to generate a large number of bubbles in the container, which quickly burst to achieve the purpose of purifying the surface of the workpiece.

Ultrasonic cleaning machines are widely used in precision hardware, electronics, semiconductors, watches, jewelry, energy, optics, medicine, automobile manufacturing, electroplating, painting and vacuum coating pre-treatment industries. They are particularly suitable for parts with complex surface shapes to wash away surface oil and dust on parts.
