20kHz Ultrasonic Vibrator Used in Mask Making Machine
Description：
The whole after connecting the transducer to the booster is called a vibrator. A device that realizes the mutual conversion of electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and amplifies the front and rear radiation covers matched by acoustic impedance.
Because the horn is a passive device, it does not generate vibration itself, but only transmits the input vibration after changing its amplitude to complete the impedance conversion.
Ultrasonic transducers can generate regular vibration under the excitation of an electric field, but the amplitude is generally about 10 μm. Such an amplitude is not enough to complete the welding and processing steps directly.
Therefore, after the transducer is connected with a properly designed booster, the amplitude of the ultrasonic wave can be changed within a large range. As long as the strength of the material is sufficient, the amplitude can exceed 100 μm.
When the luffing rod makes longitudinal telescopic vibration, the moving directions of the particles on the left and right sides of a certain cross section in the middle are exactly opposite, which is equivalent to the existence of a relatively static nodal surface. This node is called a node, and it is also the best fixation point of the vibrator. Deviating from this node will reduce the efficiency of the vibrator, commonly known as leaky waves.

The advantages of the transducer:
1. The transducer is assembled and debugged by a teacher with more than 30 years of installation experience. The assembly process is excellent and is the standard of the ultrasonic industry;
2. The consistency of the parameters of the transducer is very high, which provides convenience for customers to match the ultrasonic power supply;
3. The impedance is very small, less than 7 ohms, greatly reducing the heat and loss of the transducer;
4. The output amplitude is large, greater than or equal to 10 microns;
5. The energy conversion rate is greater than 95%;
6. The testing process is very rigorous, with an aging time of at least one week to ensure the stability of the transducer parameters.
