The ultrasonic welding vibrator 3 uses a 20kHz ultrasonic welding vibrator. The reason is as follows: the power of one cleaning vibrator is only 60W, so a set of cleaners needs to use a large number of cleaning vibrators to form an array, and the poor consistency of the array cleaning vibrators leads to the use of The rate is not high. The power of a welding vibrator can reach 1500W. After testing, it is found that when the power is high, the water splashes everywhere, and when the power is low, it can form a vortex, which forms a strong impact on the workpiece to be cleaned. Coupled with the cavitation effect, the workpiece to be cleaned can be cleaned in a short time. Rinse clean, save time and electricity, so the present invention uses a welding vibrator. Based on the hearing range of the human ear is 20-20kHz, from the perspective of noise, the present invention selects a 20kHz ultrasonic welding vibrator.
