General description

Ultrasonic cleaning equipment is used for most cases of precision cleaning. It is important to detect where the ultrasonic cleaning energy is generated and to design and produce the cleaning basket so that the workpiece can be cleaned at the optimal position.

Explanation

(1)How to detect positions where ultrasonic cleaning energy is generated

・To improve the ultrasonic cleaning effect, the workpiece must be placed at an optimal position in the cleaning basket.
・Therefore, it is important to detect how the ultrasonic cleaning energy is being generated in the cleaning tank of the ultrasonic cleaning equipment you will use.
・Fig.1 illustrates how to detect ultrasonic cleaning energy being generated in the cleaning tank.
・Using a commercially available aluminum kitchen foil, the intensity of ultrasonic energy can be relatively determined by the conditions and positions of deformation and fracture of the aluminum foil. (Fig.2)
・Fig.2 illustrates how to prepare the aluminum foil designed for detecting cleaning energy.A frame made with a rust-free stainless steel wire is used for setting the aluminum foil sheet in place.

(2)Relationship between intensity distribution of ultrasonic cleaning energy and cleaning conditions

・For ultrasonic cleaning energy, the amplitude (distance) of vibration energy is determined by the characteristics of the ultrasonic oscillators.
・The cleaning energy is distributed based on the amplitude of vibration energy and the oscillation intensity pattern.
・Therefore, to be able to stabilize the cleaning quality of workpieces in the cleaning basket, the optimal cleaning conditions (swaying motion and distance) delivering consistent cleaning energy to the workpieces must be selected by swaying the cleaning basket for the same distance as the amplitude of the vibration energy.
