Description

Cleaning liquid circulation system and circulation method for ultrasonic cleaning machine

technical field

The invention relates to the field of ultrasonic cleaning, in particular to a cleaning liquid circulation system and circulation method for an ultrasonic cleaning machine.

Background technique

Ultrasonic cleaning machine is a device that uses ultrasonic waves to clean workpieces. It generally includes loading and unloading tables, cleaning tanks and drying tanks. Cleaning liquid is stored in the cleaning tank. The high-frequency oscillation signal sent by the ultrasonic generator passes through the transducer. It is converted into high-frequency mechanical vibration and propagated into the medium-cleaning liquid. Ultrasonic waves radiate forward in the cleaning liquid, causing the liquid to flow and generate tens of thousands of tiny bubbles with a diameter of 50-500 μm, which exist in the Microscopic air bubbles in the liquid vibrate under the action of the sound field. These bubbles form and grow in the negative pressure zone where the ultrasonic wave travels longitudinally, while in the positive pressure zone, when the sound pressure reaches a certain value, the bubbles increase rapidly and then close suddenly. And when the bubble is closed, a shock wave is generated, and thousands of atmospheric pressures are generated around it, destroying the insoluble dirt and dispersing them in the cleaning solution. When the group particles are wrapped in oil and adhere to the surface of the workpiece, the oil is emulsified, and the solid particles Detachment, so as to achieve the purpose of workpiece purification.

After the workpiece is cleaned, the dirt on it will remain in the cleaning solution, and the accumulation of dirt in the cleaning solution will affect the cleaning effect of subsequent workpieces. The current mainstream method is to replace the cleaning solution regularly. However, since the workpiece usually passes through multiple cleaning tanks for multiple cleanings, the degree of contamination of the cleaning solution in each cleaning tank must be different. If all cleaning tanks are replaced and cleaned simultaneously Liquid will cause great waste and increase costs; and if the cleaning liquid in each cleaning tank is individually set to replace time, it will be time-consuming and labor-intensive, which will greatly affect work efficiency.
