High Frequency Ultrasonic Oscillator Double Welding Transducer With
Mounting Booster
Ultrasonic vibrator principle:
Ultrasonic transducer is an energy conversion device that converts
high-frequency electrical energy into mechanical energy. In fact,
it is a piezoelectric ceramic whose frequency is the same as its
resonant frequency. It uses the piezoelectric effect of the
material to convert electrical energy into mechanical vibration.
Under normal circumstances, ultrasonic waves are first generated by
an ultrasonic generator, converted into mechanical vibration by an
ultrasonic transducer, and ultrasonic waves are generated by an
ultrasonic derivation device and an ultrasonic receiving device.

Ultrasonic transducers mainly include: ultrasonic cleaning,
industrial cleaning, industrial welding, and beauty products.
The following mainly describes the role of the ultrasonic
transducer 2.
1, ultrasonic cleaning
The mechanism of ultrasonic cleaning is to use the physical effects
such as cavitation, radiation pressure and sound flow when the
ultrasonic wave propagates in the cleaning liquid, to peel off the
mechanical phenomenon generated by the dirt on the cleaning member,
and at the same time to promote the chemical reaction between the
cleaning liquid and the dirt. Reaction, to achieve the purpose of
cleaning the object. The frequency used by the ultrasonic cleaner
can be selected from 10 to 500 kHz depending on the size and
purpose of the cleaning object, and is generally 20 to 50 kHz. As
the frequency of the ultrasonic transducer increases, a Langevin
oscillator, a longitudinal vibrator, a thickness vibrator, and the
like can be used. In terms of miniaturization, there are also
radial vibrations and bending vibrations using a disk oscillator.
Ultrasonic cleaning is used more and more widely in various
industries, agriculture, household equipment, electronics,
automotive, rubber, printing, aircraft, food, hospital and medical
research.
2, 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.
