Background
The ultrasonic cleaning machine is a device for cleaning a workpiece by utilizing ultrasonic waves, and generally comprises a feeding and discharging table, a cleaning tank and a drying tank, wherein cleaning liquid is stored in the cleaning tank, a high-frequency oscillation signal sent by an ultrasonic generator is converted into high-frequency mechanical oscillation through a transducer and is transmitted to a medium, namely the cleaning liquid, the ultrasonic waves are radiated forwards at intervals in the cleaning liquid, the liquid flows to generate tens of thousands of micro-bubbles with the diameter of 50-500 mu m, and the micro-bubbles in the liquid vibrate under the action of a sound field. These bubbles are formed and grown in a negative pressure region where the ultrasonic wave propagates in the longitudinal direction, and in a positive pressure region, when the sound pressure reaches a certain value, the bubbles rapidly increase and then suddenly close. When the bubbles are closed, shock waves are generated, thousands of atmospheric pressures are generated around the bubbles, insoluble dirt is damaged, and the insoluble dirt is dispersed in the cleaning liquid, and when the group particles are wrapped by the oil dirt and adhered to the surface of a workpiece, the oil is emulsified, and solid particles are separated, so that the aim of purifying the workpiece is fulfilled.
After the workpiece is cleaned, dirt on the workpiece can be remained in the cleaning liquid, and the cleaning effect of the subsequent workpiece can be influenced after the dirt in the cleaning liquid is accumulated. At present, cleaning solution is replaced regularly, but workpieces are usually cleaned in multiple cleaning tanks, so that the pollution degree of the cleaning solution in each cleaning tank is different, if the cleaning solution is replaced synchronously for all the cleaning tanks, great waste is caused, and the cost is increased; and if the cleaning liquid in each cleaning tank is independently set for the replacement time, the time and the labor are wasted, and the working efficiency is greatly influenced.
