DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-2 The present application is further described with specific embodiments: The embodiment of the present application discloses an ultrasonic power control method of a hanging chain cleaning machine, comprising the following steps: Step 101, receiving input material information of the workpiece to be cleaned. Specifically, the workpiece to be cleaned is an object that needs to be cleaned by a hanging chain cleaning machine. These workpieces to be cleaned may come from different production links, and may have oil stains, impurities and other substances that need to be removed attached to the surface. The material properties of the workpieces are different, such as metal materials and plastic materials.

[0018] Step 102: Match the appropriate cleaning liquid temperature range for the workpiece to be cleaned based on the material information, which is recorded as the target temperature range. Specifically, different workpiece materials have different physical and chemical properties, so the cleaning liquid temperatures that can achieve better cleaning effects are different. If the temperature exceeds the appropriate range, poor cleaning effects may result.

[0019] Step 103, obtaining the first cleaning liquid temperature sent by the temperature sensor in the cleaning tank; when the obtained first cleaning liquid temperature is not within the target temperature range, starting the heating device to adjust the temperature of the cleaning liquid so that the temperature of the cleaning liquid is within the target temperature range.

[0020] Step 104: Divide the target temperature range into n sub-intervals, and obtain an ultrasonic power and temperature mapping library; the ultrasonic power and temperature mapping library contains the ultrasonic power corresponding to each sub-interval.

[0021] Step 105: Acquire current temperature data sent by the temperature sensor and determine the sub-interval in which the current temperature is located.

[0022] Step 106: Determine the ultrasonic power value corresponding to the sub-interval where the current temperature is located based on the ultrasonic power and temperature mapping library; and control the ultrasonic transducer to perform ultrasonic cleaning based on the ultrasonic power value. Specifically, the ultrasonic transducer is a device that converts electrical energy into ultrasonic vibrations. In the hanging chain cleaning machine, the ultrasonic transducer receives the electrical energy signal corresponding to the ultrasonic power value set by the control system, and then generates ultrasonic vibrations of corresponding intensity, which then act on the cleaning liquid, causing the cleaning liquid to produce cavitation effects to remove dirt and other impurities on the surface of the workpiece, thereby achieving the purpose of cleaning.

[0023] In the present application, the material information of the workpiece to be cleaned is first received from an input device, which may be an external keyboard or a touch screen; based on the material information, an appropriate cleaning liquid temperature range is matched as the target temperature range. When the actual cleaning liquid temperature in the cleaning tank is not within the target temperature range, a heating device is used to adjust the temperature to ensure that the cleaning liquid is in a suitable temperature environment. When cleaning the workpiece to be cleaned, the target temperature range is divided into a plurality of sub-intervals, and the ultrasonic power corresponding to each sub-interval is determined based on the ultrasonic power and temperature mapping library, and the sub-interval is accurately determined based on the current temperature obtained in real time by the temperature sensor, and then the ultrasonic transducer is controlled to perform ultrasonic cleaning according to the corresponding ultrasonic power value, and the ultrasonic power is dynamically adjusted according to the material characteristics of the workpiece and the real-time cleaning liquid temperature, so that the cleaning machine can clean different materials with matching ultrasonic power, effectively improving the cleaning quality and cleaning efficiency of various workpieces.

[0024] As a specific implementation of an ultrasonic power control method for a hanging chain cleaning machine, starting a heating device to adjust the temperature of a cleaning liquid so that the temperature of the cleaning liquid is within a target temperature range includes: After obtaining the first cleaning liquid temperature sent by the temperature sensor, the temperature deviation value is obtained by performing a difference calculation between the first cleaning liquid temperature and the lower limit of the target temperature range; The initial heating power of the heating regulating device is matched based on the size of the temperature deviation value: when the temperature deviation value is less than the first temperature difference value threshold, the initial heating power of the heating regulating device is set to the first power; when the temperature deviation value is greater than the first temperature difference value threshold and less than the second temperature difference value threshold, the initial heating power of the heating regulating device is set to the second power; when the temperature deviation value is greater than the second temperature difference value threshold, the initial heating power of the heating regulating device is set to the third power; wherein the first power is less than the second power; and the second power is less than the third power; The heating regulating device heats the cleaning liquid according to the initial heating power; During the heating process, the temperature of the second cleaning fluid sent by the temperature sensor is obtained and based on Get the ratio r of the difference between the current temperature and the lower limit of the target temperature range to the length of the target temperature range; where, is the upper limit of the target temperature range; The upper limit of the target temperature range is based on the ratio r The initial heating power is adjusted based on the ratio r so that the temperature of the cleaning fluid increases and is within the target temperature range; wherein, the larger the ratio r is, the smaller the adjusted heating power is.

[0025] Specifically, the temperature deviation value is obtained by calculating the difference between the first cleaning liquid temperature sent by the temperature sensor and the lower limit of the target temperature range. The initial heating power of the heating adjustment device is matched according to the size of the deviation value. If the deviation value is small, a relatively small power (such as the first power) is set, and if the deviation value is large, a larger power (such as the second power, the third power) is set. According to the degree of deviation between the actual temperature and the target temperature, the appropriate initial heating power is selected to avoid energy waste caused by excessive power or slow heating due to too little power, which affects the cleaning efficiency. During the heating process, new temperature data is obtained to calculate the ratio r of the difference between the current temperature and the lower limit of the target temperature range to the length of the target temperature range interval, and then the initial heating power is adjusted based on this ratio r. The larger the ratio r, the closer it is to the upper limit of the target temperature range. At this time, the adjusted heating power is smaller, so that the cleaning liquid temperature rises more steadily and finally falls within the target temperature range, preventing the temperature from exceeding the appropriate interval and affecting the cleaning effect and workpiece quality, and reducing energy consumption.

[0026] As a specific implementation of an ultrasonic power control method for a hanging chain cleaning machine, the construction process of an ultrasonic power and temperature mapping library includes: For each sub-interval of the target temperature range corresponding to the workpiece of each material, multiple different temperature test points are selected in the sub-interval; At each selected temperature test point, use ultrasound of different powers to conduct cleaning experiments on standard workpiece samples; record the corresponding ultrasonic power value during each experiment and the cleaning effect index value measured by the cleaning effect detection equipment after cleaning is completed; The ultrasonic power with the largest sum of cleaning effect index values ​​is selected as the ultrasonic power value adapted to the sub-interval; the sum of cleaning effect index values ​​is the sum of cleaning effect index values ​​at different temperature test points in the sub-interval.

[0027] Specifically, for each sub-interval of the target temperature range corresponding to each material workpiece, multiple test points with different temperatures are first selected, and cleaning experiments are carried out on standard workpiece samples with ultrasound of different powers at these test points, and the corresponding ultrasonic power values ​​and cleaning effect index values ​​after cleaning are recorded. Finally, the ultrasonic power with the largest total cleaning effect index value is selected as the power value adapted for the sub-interval, and the most suitable ultrasonic power is found for each temperature sub-interval. In the actual cleaning process, the system matches the corresponding optimal ultrasonic power based on the mapping library to drive the ultrasonic transducer to work, thereby maximizing the advantages of ultrasonic cleaning and ensuring high-quality cleaning of workpieces under different working conditions.

[0028] As a specific implementation of an ultrasonic power control method for a hanging chain cleaning machine, after controlling the ultrasonic transducer to perform ultrasonic cleaning based on the ultrasonic power value, the method further includes: The actual output value of ultrasonic power of the ultrasonic transducer is obtained by a power detector; Obtaining a difference between the actual ultrasonic power output value and the set ultrasonic power value based on the actual ultrasonic power output value; Matching a power deviation threshold based on a power interval in which a set ultrasonic power value is located; Determine whether the difference is greater than the power deviation threshold; if so, obtain the current supply voltage value and determine whether it is caused by voltage fluctuation; if so, start the voltage stabilization device to stabilize the voltage and re-obtain the actual ultrasonic power output value; if within the first time period, the difference between the actual ultrasonic power output value and the set ultrasonic power value is less than the power deviation threshold, it is determined that the power deviation has returned to the normal range; If it is determined that the voltage fluctuation is not the cause, the operating temperature of the ultrasonic transducer is obtained; when the operating temperature is greater than the rated temperature upper limit, the speed of the cooling fan of the ultrasonic transducer is increased.

[0029] Specifically, the actual output value of ultrasonic power is obtained through a power detector, and the difference between it and the set ultrasonic power value is calculated. Then, the power deviation threshold is matched according to the power interval in which the set power value is located to determine whether the difference exceeds the threshold, and whether the ultrasonic power output is abnormal. If the difference is greater than the threshold, it is further determined whether it is caused by voltage fluctuation. If so, the voltage stabilizing device is started to stabilize the voltage and re-detect the output value. In this way, the power deviation problem caused by unstable voltage can be corrected in time, and the ultrasonic transducer is guaranteed to work under stable power, thereby ensuring the stability of the cleaning effect. If it is determined that it is not caused by voltage fluctuation, the working temperature of the ultrasonic transducer is obtained. When the working temperature is higher than the rated temperature upper limit, the heat dissipation is enhanced by increasing the speed of the cooling fan to avoid affecting the performance of the ultrasonic transducer due to excessive temperature or even causing damage, so that it can continuously and stably output appropriate ultrasonic power for cleaning work, effectively reducing the adverse effects of power abnormality, excessive temperature and other factors on the cleaning work.

[0030] As one embodiment of the ultrasonic power control method of a hanging chain cleaning machine, the method further includes: Obtaining liquid level height data sent by a liquid level sensor in a cleaning tank; Comparing the liquid level height data with the liquid level lower limit value; When the liquid level height is lower than the lower limit value of the liquid level, the cleaning liquid replenishing device connected to the cleaning tank is started, and the cleaning liquid replenishing device is used to transport cleaning liquid into the cleaning tank; during the process of replenishing the cleaning liquid, the liquid level sensor continuously monitors the liquid level changes, and when the liquid level reaches the upper limit value of the liquid level, a stop command is sent to the cleaning liquid replenishing device to enable the cleaning liquid replenishing device to replenish the cleaning liquid.

[0031] Specifically, by obtaining the liquid level height data sent by the liquid level sensor in the cleaning tank and comparing it with the lower limit of the liquid level, the system can know the inventory of the cleaning liquid in the cleaning tank in real time. When the liquid level height is lower than the lower limit of the liquid level, the cleaning liquid replenishing device connected to the cleaning tank is started in time to ensure that there is always sufficient cleaning liquid in the cleaning tank to meet the needs of ultrasonic cleaning work, avoiding the situation where the cleaning effect is greatly reduced or even the cleaning operation cannot be carried out normally due to insufficient cleaning liquid. In the process of replenishing the cleaning liquid, the liquid level sensor continuously monitors the changes in the liquid level. Once the liquid level reaches the upper limit of the liquid level, it sends a stop command to the cleaning liquid replenishing device, preventing waste caused by excessive replenishment of cleaning liquid, and avoiding problems such as overflow of cleaning liquid caused by excessive replenishment.

[0033] As one embodiment of the ultrasonic power control method of a hanging chain cleaning machine, the method further includes: After the workpiece is cleaned, the cleaning effect index value of the workpiece is detected by the cleaning effect detection equipment; when the cleaning effect index value is lower than the preset index value, the current ultrasonic power and temperature value are recorded and sent to the external device.
