Precision Automatic Cleaning System Electronic Components Three Slot 20KHz Frequency

What is the principle of ultrasonic cleaning?
The ultrasonic cleaning machine converts the oscillating signal higher than the frequency of 20KHz by the ultrasonic generator and then converts it into high-frequency mechanical vibration energy through the inverse piezoelectric effect of the ultrasonic transducer (shock) to clean the sound radiation in the liquid. The cleaning liquid molecules vibrate and produce numerous tiny holes and bubbles. And it forms and grows in the negative pressure zone along the direction of ultrasonic wave propagation, and instantaneously closes in the positive pressure zone to generate high-pressure blasting between thousands of atmospheres, forming numerous micro-high-pressure shock waves acting on the scale impurities of the pipeline and smashing it. . This is called the "cavitation effect" in ultrasonic cleaning. The copper tube ultrasonic cleaning machine works based on the "cavitation effect" technology. From the "cavitation effect", it is known that holes and bubbles are generated by applying high-frequency (ultrasonic frequency), high-intensity sound waves to a liquid. To this end, the composition of the copper tube ultrasonic cleaning machine must have the following two basic components: an ultrasonic generator for high-frequency, high-voltage, high-power electrical signals, and an electrical energy capable of converting electrical energy into mechanical energy (ie, piezoelectric inverse performance) and passing through the liquid. Pipeline high sound intensity transducer.

Advantages of ultrasonic cleaning machine for electronic components:

1. Ultrasonic cleaning can greatly improve the cleanliness of the surface of the parts being cleaned. According to the data, if the ultrasonic cleaning effect is 100%, the brushing (using chemical reagents) is 90%, the steam cleaning (chemical solvent) is 35%, the solvent pressure cleaning is 30%, and the solvent immersion is 15%.

2. The cleaning speed is fast and the work efficiency is high, which greatly reduces the labor intensity of the cleaning operation, especially the large-volume small parts (or parts), especially suitable for ultrasonic cleaning. The application of the ultrasonic cleaning machine facilitates the implementation of the cleaning process and the process. Continuous automation. For example: Ultrasonic cleaning machine with IGBT as the main power component (frequency 20-50KHZ), its circuit is simplified, the whole machine has high reliability, the efficiency can reach 90%, the power factor is above 0.95, the volume is small, the weight is light, the power is adjustable. And frequency tracking, scanning, flexible operation, especially the single machine power can reach more than 5KW, which is of great significance for large-scale ultrasonic cleaning.

3. Fragile articles or parts that are not suitable for cleaning with other cleaning processes, or parts (or parts)
