[0002] Ultrasonic cleaning equipment plays a vital role in numerous industries, efficiently removing dirt and impurities from object surfaces. With ever-increasing demands for cleaning quality and efficiency, the need for performance optimization in ultrasonic cleaning equipment is also growing. However, current ultrasonic cleaning equipment faces several challenges in transducer frequency adjustment. Most current transducer frequency adjustments rely on fixed preset values ​​or simple manual adjustments. This approach lacks flexibility and adaptability. Different cleaning tasks, objects, and cleaning fluid characteristics all impose varying requirements on the transducer frequency. A fixed frequency cannot fully utilize the equipment's optimal performance. Often, frequency mismatch leads to poor cleaning results and may even damage the object being cleaned. Furthermore, existing adjustment methods cannot dynamically adjust based on changes during the cleaning process, frequently requiring manual experimentation with different frequencies. This significantly impacts cleaning efficiency and quality, resulting in low accuracy and efficiency in dynamic transducer frequency adjustment.

[0066] This invention determines the cleaning temperature value corresponding to the target cleaning object by combining the target cleaning object and the application scenario. This allows for an accurate determination of the upper limit of temperature that the target cleaning object can withstand during the cleaning process, facilitating subsequent setting of the cavitation temperature value. The ultrasonic cleaning equipment is a device that utilizes the cavitation effect generated by ultrasound in a liquid to achieve the cleaning purpose. The target cleaning liquid is the liquid used to clean the target cleaning object during the ultrasonic cleaning process. The target cleaning object is the item to be cleaned, which can be an object of various shapes, sizes, and materials. The application scenario is the usage scenario corresponding to the target cleaning object. The cleaning temperature value is the optimal cleaning temperature for the target cleaning object during the cleaning process. Optionally, the application scenario corresponding to the target cleaning object can be obtained by consulting the product manual of the target cleaning object.

[0067] As an embodiment of the present invention, determining the cleaning temperature value corresponding to the target cleaning object by combining the target cleaning object and the application scenario includes: identifying the name of the target object corresponding to the target cleaning object; determining the cleaning material and material ratio of the target cleaning object based on the name of the target object; querying the yield temperature of the material corresponding to the cleaning material; calculating the yield temperature value corresponding to the target cleaning object by combining the yield temperature, the cleaning material, and the material ratio; detecting the associated object corresponding to the application scenario; and determining the cleaning temperature value corresponding to the target cleaning object by combining the yield temperature value and the scenario temperature.

[0068] Wherein, the material of the cleaning object is the basic constituent material of the target cleaning object, the yield temperature of the material is the maximum temperature that the material of the cleaning object can withstand, the yield temperature value is the maximum temperature that the target cleaning object can withstand, and the scene temperature is the temperature in the application scene.

[0070] Furthermore, as an optional embodiment of the present invention, the step of calculating the yield temperature value corresponding to the target cleaned material by combining the yield temperature of the material, the material of the cleaned object, and the material ratio includes: querying the material performance value corresponding to the material of the cleaned object, querying the cleaned object performance value corresponding to the target cleaned object, calculating the interaction coefficient between the cleaned object materials by combining the material performance value and the cleaned object performance value, and calculating the yield temperature value corresponding to the target cleaned object by combining the interaction coefficient, the material yield temperature, and the material ratio using the following formula:

[0071]

[0072] Where A represents the yield temperature value corresponding to the target cleaning material, B a This represents the yield temperature of the a-th substance in the material being cleaned, in °C. a D represents the material percentage of the a-th substance in the cleaning material. abThis represents the interaction coefficient between the a-th and b-th substances in the cleaning material, where a and b represent the sequence numbers of the cleaning material, and x represents the quantity of the cleaning material.

[0073] Wherein, the material performance value is the specific quantitative value of the performance corresponding to the material of the cleaning object, the cleaning object performance value is the specific quantitative value of the performance corresponding to the target cleaning object, the interaction coefficient represents the degree of mutual influence between the materials of the cleaning object, and further, the material performance value and the cleaning object performance value can be obtained by consulting industry standard documents.

[0074] S2. Based on the cleaning temperature value, set the cavitation temperature value corresponding to the target cleaning fluid, determine the gas nucleus pressure value corresponding to the cavitation gas nuclei generated in the target cleaning fluid, and obtain the gas adiabatic index in the target cleaning fluid. Combining the cavitation temperature value, the gas nucleus pressure value, and the gas adiabatic index, calculate the gas nucleus annihilation pressure of the cavitation gas nuclei generated in the target cleaning fluid.

[0075] This invention determines the pressure value of the cavitation gas nuclei generated in the target cleaning fluid by identifying the gas nuclei pressure value corresponding to the cavitation gas nuclei. This provides a basis for calculating the subsequent annihilation pressure of the gas nuclei. The cavitation temperature value is the maximum temperature of the gas nuclei when cavitation occurs in the target cleaning fluid, which is the cleaning temperature value. The gas nuclei pressure value is the internal pressure of the cavitation gas nuclei generated in the target cleaning fluid. The cavitation gas nuclei are the bubbles generated in the target cleaning fluid. The gas adiabatic index is an important parameter of the thermodynamic properties of the gas in the target cleaning fluid during an adiabatic process (i.e., a process without heat exchange with the outside). Optionally, the gas adiabatic index in the target cleaning fluid can be obtained by querying an adiabatic index database.

[0076] As an embodiment of the present invention, determining the gas core pressure value corresponding to the cavitation gas core generated in the target cleaning fluid includes: identifying the gas core position corresponding to the cavitation gas core generated in the target cleaning fluid; calculating the gas core distance between the cavitation gas cores based on the gas core position; determining the gas core measurement position of the cavitation gas core according to the gas core distance; recording the gas core existence period corresponding to the cavitation gas core; determining the measurement frequency corresponding to the cavitation gas core according to the gas core existence period; and measuring the matching pressure value of the cavitation gas core by combining the measurement frequency, the gas core existence period and the matching measurement position.

[0077] Wherein, the gas nucleus position is the location of the cavitation gas nucleus in the target cleaning fluid; the gas nucleus distance represents the distance between the cavitation gas nuclei; the gas nucleus measurement position is the position where the instrument is placed when detecting the gas nuclei in the target cleaning fluid; and the gas nucleus duration is the duration corresponding to the cavitation gas nucleus.

The measurement frequency corresponding to the cavitation gas nucleus is set for each time interval. For gas nuclei with short duration, a higher measurement frequency can be set, such as 20 times, to more accurately capture their changes and characteristics. For gas nuclei with medium duration, the measurement frequency can be moderate, such as 12 times. For gas nuclei with long duration, the measurement frequency can be appropriately reduced, such as 6 times. Combining the measurement frequency, the duration of the gas nucleus, and the matching measurement position, the pressure value of the cavitation gas nucleus is measured, and the number of cavitation gas nuclei is counted. Combining the number of gas nuclei and the pressure value, the average pressure value of the cavitation gas nucleus is calculated. Based on the average pressure value, the matching pressure value is obtained.

[0078] Furthermore, as an optional embodiment of the present invention, determining the gas core measurement position of the cavitation gas core based on the gas core distance includes: calculating the mean gas core distance corresponding to the cavitation gas core based on the gas core distance; calculating the gas core distance variance corresponding to the cavitation gas core by combining the gas core distance and the mean gas core distance; dividing the cavitation gas core into regions based on the gas core distance variance to obtain gas core regions; performing clustering processing on the gas core regions to obtain clustered gas core regions; calculating the region center corresponding to the clustered gas core regions; and determining the gas core measurement position of the cavitation gas core based on the region center.

[0079] Wherein, the gas core distance variance represents the dispersion of the cavitation gas core, the gas core region is the cavitation gas core divided into different sub-regions, and the clustered gas core region is the region formed by the clustering of similar regions within the gas core region. Furthermore, the mean gas core distance corresponding to the cavitation gas core can be realized using the average function; the calculation of the gas core distance variance corresponding to the cavitation gas core can be realized using a variance calculator; the minimum variance among the gas core distance variances is identified, and the cavitation gas core is manually divided into regions to obtain the gas core region; the clustering processing of the gas core region can be realized using the K-Means clustering algorithm; the region center corresponding to the clustered gas core region can be obtained by calculating the average value.

[0080] This invention calculates the annihilation pressure of cavitation nuclei generated in the target cleaning fluid by combining the cavitation temperature value, the nucleus pressure value, and the gas adiabatic index. This allows us to obtain the maximum pressure value corresponding to the annihilation of the cavitation nuclei, thus providing a basis for the subsequent calculation of the peak nucleus pressure. The nucleus annihilation pressure is the maximum pressure required for the annihilation of the cavitation nuclei.

[0081] As an embodiment of the present invention, the step of calculating the nucleus annihilation pressure of the cavitation nuclei generated in the target cleaning fluid by combining the cavitation temperature value, the nucleus pressure value, and the gas adiabatic index includes: measuring the liquid temperature corresponding to the target cleaning fluid, and calculating the nucleus annihilation pressure of the cavitation nuclei generated in the target cleaning fluid by combining the cavitation temperature value, the nucleus pressure value, the liquid temperature, and the gas adiabatic index using the following formula:

[0082]

[0083] Where F represents the nucleus annihilation pressure of the cavitation gas nuclei generated in the target cleaning fluid, and E max E represents the cavitation temperature value. min G represents the temperature of the liquid. d This represents the pressure value of the d-th cavitation nucleus, where d represents the sequence number of the cavitation nucleus.

[0084] The liquid temperature is the normal temperature of the target cleaning fluid. Furthermore, the liquid temperature corresponding to the target cleaning fluid can be measured using the aforementioned temperature monitoring meter.

[0085] S3. Combining the annihilation pressure of the gas nucleus, the gas nucleus pressure value, and the gas adiabatic index, calculate the peak gas nucleus pressure corresponding to the cavitation gas nucleus, detect the static pressure value corresponding to the target cleaning fluid, and calculate the gas nucleus resonance frequency corresponding to the cavitation gas nucleus based on the peak gas nucleus pressure and the static pressure value.

[0086] This invention calculates the peak pressure of the cavitation nucleus by combining the nucleus annihilation pressure, the nucleus pressure value, and the gas adiabatic index. The peak pressure value indicates the highest pressure reached within the cavitation nucleus during compression by an external force, facilitating subsequent calculation of the nucleus resonance frequency. The peak pressure is the highest pressure reached within the cavitation nucleus during compression by an external force, and the static pressure value is the pressure of the target cleaning fluid under static conditions. Furthermore, the static pressure value of the target cleaning fluid can be detected using a pressure gauge.

[0087] As an embodiment of the present invention, the step of calculating the peak gas nucleus pressure corresponding to the cavitation gas nucleus by combining the gas nucleus annihilation pressure, the gas nucleus pressure value, and the gas adiabatic index includes:

[0088]

[0089] Among them, F max G represents the peak pressure of the cavitation nucleus. d F represents the nucleus pressure value corresponding to the d-th cavitation nucleus. d β represents the annihilation pressure of the d-th cavitation nucleus, where d represents the sequence number of the cavitation nucleus and β represents the gas adiabatic index.

[0090] Based on the peak pressure of the gas nucleus and the static pressure value, this invention calculates the resonant frequency of the cavitation gas nucleus, which can obtain the frequency value when the cavitation gas nucleus resonates under ultrasonic cleaning. This facilitates the subsequent adjustment of the transducer frequency of the ultrasonic cleaning equipment. The resonant frequency of the gas nucleus is the resonant frequency corresponding to the cavitation gas nucleus. When the transducer frequency of the ultrasonic cleaning equipment is the same as the resonant frequency of the gas nucleus, the cleaning efficiency reaches its optimal level.

[0091] As an embodiment of the present invention, the step of calculating the resonant frequency of the cavitation gas nucleus based on the peak pressure of the gas nucleus and the static pressure value includes: acquiring a gas nucleus image corresponding to the cavitation gas nucleus, extracting the main body of the gas nucleus from the gas nucleus image, determining the radius of the gas nucleus corresponding to the cavitation gas nucleus based on the main body of the gas nucleus, measuring the liquid density corresponding to the target cleaning fluid, and calculating the resonant frequency of the cavitation gas nucleus based on the liquid density, the gas nucleus radius, the peak pressure of the gas nucleus, and the static pressure value using the following formula:

[0092]

[0093] Where H represents the nuclear resonance frequency corresponding to the cavitation nucleus, and F max ρ represents the peak pressure of the gas core, L represents the radius of the gas core, h represents the static pressure value, and ρ represents the density of the cleaning fluid.

[0094] Wherein, the gas core image is the image corresponding to the cavitation gas core, and the gas core body is the image obtained after removing images unrelated to the gas core from the gas core image. Furthermore, the gas core image corresponding to the cavitation gas core can be obtained by taking a picture with a camera; the extraction of the gas core body in the gas core image can be achieved by an extraction tool, which is compiled by a programming language; based on the image parameters of the gas core body, the pixel area of ​​the gas core is calculated, and then the actual area is calculated according to the image resolution and scale, thereby calculating the gas core radius corresponding to the cavitation gas core; the liquid density corresponding to the target cleaning fluid can be measured by a densitometer.

[0095] S4. Based on the static pressure value, calculate the cleaning fluid intensity corresponding to the target cleaning fluid. Based on the cleaning fluid intensity and the gas nucleus resonance frequency, perform the adjustment process of the transducer frequency of the ultrasonic cleaning equipment to obtain the adjustment result.

[0096] This invention calculates the cleaning fluid intensity corresponding to the target cleaning fluid by combining the static pressure value, thereby understanding the magnitude of the cohesive force of the target cleaning fluid. This provides a basis for the subsequent adjustment of the transducer frequency of the ultrasonic cleaning equipment. The cleaning fluid intensity represents a description of the cohesive force within the target cleaning fluid.

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

[0098]

[0099] Where M represents the cleaning fluid intensity 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 initial radius of the cavitation nucleus in the target cleaning fluid.

[0100] Wherein, the equilibrium vapor pressure represents the target cleaning fluid, the surface free energy represents the target cleaning fluid, and the initial radius is the radius corresponding to the cavitation nucleus at the beginning in the target cleaning fluid. Furthermore, the equilibrium vapor pressure of the target cleaning fluid can be measured by a vapor pressure measuring instrument; the surface free energy of the target cleaning fluid can be measured by the Wilhelmy plate method, in which a vertical thin plate is inserted into the cleaning fluid, the force acting on the plate is measured, and the surface free energy is calculated.

[0101] This invention improves the accuracy of ultrasonic cleaning device head frequency adjustment by combining the cleaning fluid strength and the gas nucleus resonance frequency. Furthermore, by adjusting the head frequency to match the gas nucleus resonance frequency, the cleaning fluid strength is graded into low, medium, and high levels. Assuming the gas nucleus resonance frequency is 45kHz, a low cleaning fluid strength indicates weak cleaning ability. In this case, the head frequency can be appropriately increased, for example, from 45kHz to 50kHz, to enhance cavitation effect and cleaning performance. If the cleaning fluid strength is medium, the head frequency is maintained near the gas nucleus resonance frequency of 45kHz, possibly fine-tuned to 44kHz or 46kHz, to ensure a certain cleaning effect while considering device stability and energy consumption. When the cleaning fluid strength is high, indicating strong cleaning ability, the head frequency can be slightly reduced, for example, to 40kHz, to avoid excessive impact and damage to the cleaned objects, thus achieving head frequency adjustment.

[0102] This invention, by combining the target cleaning object and the application scenario, determines the corresponding cleaning temperature value of the target cleaning object, accurately obtaining the upper limit of the temperature the target cleaning object can withstand during the cleaning process, thus facilitating the subsequent setting of the cavitation temperature value. By determining the nucleus pressure value corresponding to the cavitation nuclei generated in the target cleaning fluid, this invention obtains the pressure magnitude inside the nuclei formed when cavitation occurs in the target cleaning fluid, thus providing a basis for the subsequent calculation of the nucleus annihilation pressure. By combining the nucleus annihilation pressure, the nucleus pressure value, and the gas adiabatic index, this invention calculates the peak nucleus pressure corresponding to the cavitation nucleus, which can reveal the highest pressure reached inside the nucleus during compression by external forces, thus facilitating the subsequent calculation of the nucleus resonance frequency. By combining the static pressure value, this invention calculates the cleaning fluid strength corresponding to the target cleaning fluid, revealing the magnitude of the cohesive force of the target cleaning fluid, thus providing a basis for the subsequent adjustment of the transducer frequency of the ultrasonic cleaning equipment. Therefore, the method for dynamically adjusting the transducer frequency of an ultrasonic cleaning device provided in this embodiment of the invention can improve the accuracy of the dynamic adjustment of the transducer frequency of the ultrasonic cleaning device.
