[0002] Ultrasonic cleaning equipment plays an important role in many industries. It can efficiently remove dirt and impurities from the surface of objects. With the continuous improvement of cleaning quality and efficiency requirements, the demand for performance optimization of ultrasonic cleaning equipment is also growing. However, there are some problems in the frequency adjustment of the vibration head of ultrasonic cleaning equipment. The vibration head frequency adjustment of current ultrasonic cleaning equipment mostly adopts fixed preset values ​​or simple manual adjustment methods. This adjustment method lacks flexibility and adaptability. Different cleaning tasks, cleaning objects and cleaning liquid characteristics have different requirements for the vibration head frequency. The fixed frequency cannot give full play to the best performance of the cleaning equipment. In many cases, due to frequency mismatch, the cleaning effect is poor and may even cause damage to the cleaning object.

[0071]

[0072] Where A represents the yield temperature value of the target cleaning object, B a Indicates the yield temperature of the ath material in the cleaning material, C a Indicates the material proportion of the ath substance in the cleaning material, D abIt represents the interaction coefficient between the a-th and b-th substances in the cleaning material, a and b represent the serial numbers of the cleaning materials respectively, and x represents the number of the cleaning materials.

In combination with the measurement frequency, the lifetime of the gas nucleus and the matching measurement position, the pressure value of the cavitation gas nucleus is measured, and the number of the gas nuclei of the cavitation gas nucleus is counted. In combination with the number of gas nuclei and the pressure value, the average pressure value of the cavitation gas nucleus is calculated, and the matching pressure value is obtained based on the average pressure value.

The gas core pressure peak value is the maximum value of the pressure reached inside the gas core when the cavitation gas core is compressed by an external force, and the static pressure value is the pressure corresponding to the target cleaning fluid under static conditions. Furthermore, the detection of the static pressure value corresponding to the target cleaning fluid can be achieved by a pressure detector.

[0090] The present invention calculates the gas core resonance frequency corresponding to the cavitation gas core based on the gas core pressure peak value and the static pressure value, and can obtain the frequency value of the cavitation gas core when resonance occurs under ultrasonic cleaning, which is convenient for the subsequent adjustment of the vibration head frequency of the ultrasonic cleaning equipment, wherein the gas core resonance frequency is the resonance frequency corresponding to the cavitation gas core. When the vibration head frequency of the ultrasonic cleaning equipment is the same as the gas core resonance frequency, the cleaning efficiency reaches the best.

[0091] As an embodiment of the present invention, the gas core resonance frequency corresponding to the cavitation gas core is calculated based on the gas core pressure peak value and the static pressure value, including: collecting the gas core image corresponding to the cavitation gas core, extracting the gas core body in the gas core image, determining the gas core radius corresponding to the cavitation gas core based on the gas core body, measuring the liquid density corresponding to the target cleaning liquid, combining the liquid density, the gas core radius, the gas core pressure peak value and the static pressure value, and calculating the gas core resonance frequency corresponding to the cavitation gas core by the following formula:

[0097] As an embodiment of the present invention, the calculation of the cleaning liquid strength corresponding to the target cleaning liquid in combination with the static pressure value includes: measuring the equilibrium vapor pressure corresponding to the target cleaning liquid, calculating the surface free energy corresponding to the target cleaning liquid, and combining the equilibrium vapor pressure, the surface free energy and the static pressure value to calculate the cleaning liquid strength corresponding to the target cleaning liquid by the following formula:

[0098]

[0099] Wherein, M represents the cleaning fluid strength corresponding to the target cleaning fluid, N represents the equilibrium vapor pressure, P represents the surface free energy, h represents the static pressure value, and L0 represents the starting radius of the cavitation core in the target cleaning fluid.

[0100] Among them, the equilibrium vapor pressure represents the target cleaning liquid, the surface free energy represents the target cleaning liquid, the starting radius is the radius corresponding to the cavitation gas nucleus in the target cleaning liquid at the beginning, and further, the measurement of the equilibrium vapor pressure corresponding to the target cleaning liquid can be achieved by a vapor pressure measuring instrument; the surface free energy corresponding to the target cleaning liquid can be measured by the Wilhelmy plate method, a vertical thin plate is inserted into the cleaning liquid, the force acting on the plate is measured, and the surface free energy is calculated.

[0101] The present invention combines the cleaning fluid strength and the air core resonance frequency to perform the adjustment processing of the vibration head frequency of the ultrasonic cleaning equipment, so as to improve the adjustment accuracy of the vibration head frequency of the ultrasonic cleaning equipment. Furthermore, the vibration head frequency is adjusted to be consistent with the air core resonance frequency, and the cleaning fluid strength is graded into three levels: low, medium and high. Assuming that the air core resonance frequency is 45kHz, if the cleaning fluid strength is low, it means that the cleaning fluid has weak decontamination ability. At this time, the vibration head frequency can be appropriately increased, such as increasing the vibration head frequency from 45kHz to 50kHz, so as to enhance the cavitation effect and the cleaning effect. If the cleaning fluid strength is medium, the vibration head frequency is maintained near the air core resonance frequency of 45kHz, and may be fine-tuned to 44kHz or 46kHz, so as to ensure a certain cleaning effect while taking into account the stability and energy consumption of the equipment. When the cleaning fluid strength is high, it indicates that it has strong decontamination ability. In order to avoid excessive impact and damage to the cleaning object, the vibration head frequency can be slightly reduced, such as adjusted to 40kHz, to achieve the adjustment processing of the vibration head frequency.

[0102] The present invention determines the cleaning temperature value corresponding to the target cleaning object by combining the target cleaning object and the application scenario, and can accurately obtain the upper limit of the temperature that the target cleaning object can withstand during the cleaning process, thereby facilitating the subsequent setting of the cavitation temperature value. The present invention determines the gas core pressure value corresponding to the cavitation gas nucleus generated in the target cleaning liquid, and can obtain the pressure inside the gas core formed when cavitation occurs in the target cleaning liquid, thereby providing a basis for the subsequent calculation of the gas core annihilation pressure. The present invention calculates the gas core pressure peak value corresponding to the cavitation gas nucleus by combining the gas core annihilation pressure, the gas core pressure value and the gas adiabatic index. The gas core pressure peak value can be used to understand the maximum value of the pressure reached in the gas core during the compression of the cavitation gas nucleus by the external force, thereby facilitating the subsequent calculation of the gas core resonance frequency. The present invention calculates the cleaning liquid strength corresponding to the target cleaning liquid by combining the static pressure value, and can understand the cohesive force corresponding to the target cleaning liquid, thereby providing a basis for the subsequent adjustment of the vibration head frequency of the ultrasonic cleaning equipment. Therefore, the embodiment of the present invention provides a method for dynamically adjusting the frequency of a vibration head of an ultrasonic cleaning device, which can improve the accuracy of the dynamic adjustment of the frequency of a vibration head of an ultrasonic cleaning device.
