Technical Field

[0001] This application relates to the technical field of cleaning machines, and in particular to an ultrasonic power control method and system for a suspended chain cleaning machine. Background Technology

[0002] A suspended chain cleaning machine is a device that uses a suspended chain to transport workpieces for cleaning. It removes dirt from the surface of the workpieces through ultrasonic cleaning and other methods, thereby improving the cleanliness of the workpieces.

[0003] In ultrasonic cleaning, the temperature of the cleaning solution has a significant impact on the cleaning effect. The suitable temperature range of the cleaning solution varies for different materials. Traditional overhead conveyor cleaning machines often use a fixed ultrasonic power setting or maintain the cleaning solution within a general temperature range. This leads to a mismatch between temperature and ultrasonic power when cleaning different materials, resulting in either incomplete cleaning with excessive residual contaminants that affect workpiece quality, or energy waste.

[0004] Solving this technical problem is a technical challenge that needs to be overcome by those skilled in the art. Summary of the Invention

[0010] The temperature of the first cleaning fluid sent by the temperature sensor in the cleaning tank is obtained; when the obtained temperature of the first cleaning fluid is not within the target temperature range, the heating device is activated to adjust the temperature of the cleaning fluid so that the temperature of the cleaning fluid is within the target temperature range.

[0011] The target temperature range is divided into n sub-intervals, and an ultrasonic power-temperature mapping library is obtained; the ultrasonic power-temperature mapping library contains the ultrasonic power corresponding to each sub-interval;

[0012] Acquire the current temperature data sent by the temperature sensor and determine the sub-range in which the current temperature is located;

[0013] The ultrasonic power value corresponding to the sub-interval of the current temperature is determined based on the ultrasonic power and temperature mapping library; the ultrasonic transducer is controlled to perform ultrasonic cleaning based on the ultrasonic power value.

[0014] Optionally, the heating device is activated to adjust the temperature of the cleaning fluid so that the temperature of the cleaning fluid is within the target temperature range, including:

[0015] After the temperature sensor sends the temperature of the first cleaning fluid, the temperature deviation value is calculated by the difference between the temperature of the first cleaning fluid and the lower limit of the target temperature range.

[0016] The initial heating power of the heating adjustment device is matched based on the magnitude of the temperature deviation value: when the temperature deviation value is less than a first temperature difference threshold, the initial heating power of the heating adjustment device is set to a first power; when the temperature deviation value is greater than the first temperature difference threshold and less than a second temperature difference threshold, the initial heating power of the heating adjustment device is set to a second power; when the temperature deviation value is greater than the second temperature difference threshold, the initial heating power of the heating adjustment device is set to a third power; wherein, the first power is less than the second power; and the second power is less than the third power.

[0017] The heating regulating device heats the cleaning solution according to the initial heating power;

[0018] During the heating process, the temperature of the second cleaning fluid sent by the temperature sensor is acquired and based on... 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 is obtained; where, This represents the upper limit of the target temperature range. The upper limit of the target temperature range is based on the ratio r.

[0019] The initial heating power is adjusted based on a ratio r to raise the temperature of the cleaning fluid and bring it within the target temperature range; wherein, the larger the ratio r, the smaller the adjusted heating power.

[0020] Optionally, the construction process of the ultrasonic power-temperature mapping library includes:

[0021] For each sub-interval of the target temperature range corresponding to each type of workpiece material, multiple different temperature test points are selected within the sub-interval;

[0022] At each selected temperature test point, ultrasonic cleaning experiments were conducted on standard workpiece samples using ultrasonic power of different magnitudes; the ultrasonic power value corresponding to each experiment and the cleaning effect index value measured by the cleaning effect detection equipment after cleaning were recorded;

The cleaning fluid replenishment device is used to deliver cleaning fluid into the cleaning tank. During the replenishment process, the liquid level sensor continuously monitors the liquid level change. When the liquid level reaches the upper limit, a stop command is sent to the cleaning fluid replenishment device to enable it to replenish the cleaning fluid.

[0034] Optionally, after receiving the input material information of the workpiece to be cleaned, the method further includes:

[0051] The following is in conjunction with the appendix Figure 1-2 The present application will be further described with reference to specific embodiments:

[0052] This application discloses an ultrasonic power control method for a suspended chain cleaning machine, comprising the following steps:

[0053] Step 101: Receive the material information of the workpiece to be cleaned. Specifically, the workpiece to be cleaned is an object that needs to be cleaned by a suspended chain cleaning machine. These workpieces may come from different manufacturing stages, and their surfaces may have oil stains, impurities, and other substances that need to be removed. Their material properties vary, for example, they may be made of metal or plastic.

[0054] Step 102: Based on the material information, match a suitable cleaning solution temperature range for the workpiece to be cleaned, denoted as the target temperature range. Specifically, different workpiece materials have different physicochemical properties, and therefore require different cleaning solution temperatures to achieve good cleaning results. Exceeding the suitable range may result in poor cleaning performance.

[0055] Step 103: Obtain the first cleaning fluid temperature sent by the temperature sensor in the cleaning tank; when the obtained first cleaning fluid temperature is not within the target temperature range, start the heating device to adjust the temperature of the cleaning fluid so that the temperature of the cleaning fluid is within the target temperature range.

[0056] Step 104: Divide the target temperature range into n sub-intervals and obtain an ultrasonic power-temperature mapping library; the ultrasonic power-temperature mapping library contains the ultrasonic power corresponding to each sub-interval.

[0057] Step 105: Obtain the current temperature data sent by the temperature sensor and determine the sub-interval in which the current temperature is located.

[0058] Step 106: Determine the ultrasonic power value corresponding to the sub-interval of the current temperature based on the ultrasonic power and temperature mapping library; control the ultrasonic transducer to perform ultrasonic cleaning based on the ultrasonic power value. Specifically, an ultrasonic transducer is a device that converts electrical energy into ultrasonic vibration. In a suspended 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 in turn act on the cleaning fluid, causing cavitation and other effects in the cleaning fluid to remove dirt and other impurities from the surface of the workpiece, thus achieving the purpose of cleaning.

[0059] In this application, the material information of the workpiece to be cleaned is first received from an input device, which can be an external keyboard or a touch screen. A suitable cleaning fluid temperature range is then matched as the target temperature range based on the material information. When the actual temperature of the cleaning fluid in the cleaning tank is not within the target temperature range, a heating device is used to adjust it, ensuring the cleaning fluid is in a suitable temperature environment. During the cleaning of the workpiece, the target temperature range is divided into multiple sub-intervals, and the ultrasonic power corresponding to each sub-interval is determined based on an ultrasonic power-temperature mapping library. The current temperature obtained in real-time by a temperature sensor accurately determines the sub-interval, and the ultrasonic transducer is then controlled to perform ultrasonic cleaning according to the corresponding ultrasonic power value. The ultrasonic power is dynamically adjusted based on the workpiece material characteristics and the real-time cleaning fluid temperature, enabling the cleaning machine to clean different materials with matched ultrasonic power, effectively improving the cleaning quality and efficiency for various workpieces.

[0060] As a specific implementation of an ultrasonic power control method for a suspended chain cleaning machine, the heating device is activated to adjust the temperature of the cleaning fluid so that the temperature of the cleaning fluid is within the target temperature range, including:

[0061] After the temperature sensor sends the temperature of the first cleaning fluid, the temperature deviation value is calculated by the difference between the temperature of the first cleaning fluid and the lower limit of the target temperature range.

[0062] The initial heating power of the heating adjustment device is matched based on the magnitude of the temperature deviation value: when the temperature deviation value is less than a first temperature difference threshold, the initial heating power of the heating adjustment device is set to a first power; when the temperature deviation value is greater than the first temperature difference threshold and less than a second temperature difference threshold, the initial heating power of the heating adjustment device is set to a second power; when the temperature deviation value is greater than the second temperature difference threshold, the initial heating power of the heating adjustment device is set to a third power; wherein, the first power is less than the second power; and the second power is less than the third power.

[0063] The heating regulating device heats the cleaning solution according to the initial heating power;

[0064] During the heating process, the temperature of the second cleaning fluid sent by the temperature sensor is acquired and based on... 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 is obtained; where, This represents the upper limit of the target temperature range. The upper limit of the target temperature range is based on the ratio r.

[0065] The initial heating power is adjusted based on a ratio r to raise the temperature of the cleaning fluid and bring it within the target temperature range; wherein, the larger the ratio r, the smaller the adjusted heating power.

[0066] Specifically, the temperature deviation is calculated by comparing the temperature of the first cleaning fluid sent by the temperature sensor with the lower limit of the target temperature range. The initial heating power of the heating adjustment device is then matched based on the magnitude of this deviation. A smaller deviation results in a lower power (e.g., the first power), while a larger deviation results in a higher power (e.g., the second or third power). The appropriate initial heating power is selected based on the degree of deviation between the actual temperature and the target temperature to avoid energy waste from excessive power or slow heating due to insufficient power, which would affect cleaning efficiency. During the heating process, new temperature data is acquired, and 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 is calculated. The initial heating power is then adjusted based on this ratio *r*. A larger ratio *r* means the temperature is closer to the upper limit of the target temperature range, resulting in a lower adjusted heating power. This allows the cleaning fluid temperature to rise more steadily and ultimately remain within the target temperature range, preventing the temperature from exceeding the appropriate range and affecting the cleaning effect and workpiece quality, while also reducing energy consumption.

[0067] As a specific implementation method of ultrasonic power control for a suspended chain cleaning machine, the process of constructing an ultrasonic power-temperature mapping library includes:

[0068] For each sub-interval of the target temperature range corresponding to each type of workpiece material, multiple different temperature test points are selected within the sub-interval;

[0069] At each selected temperature test point, ultrasonic cleaning experiments were conducted on standard workpiece samples using ultrasonic power of different magnitudes; the ultrasonic power value corresponding to each experiment and the cleaning effect index value measured by the cleaning effect detection equipment after cleaning were recorded;

[0070] The ultrasonic power with the largest sum of cleaning effect index values ​​is selected as the ultrasonic power value for sub-interval adaptation; the sum of cleaning effect index values ​​is the sum of cleaning effect index values ​​at different temperature test points in the sub-interval.

[0071] Specifically, for each sub-range of the target temperature range corresponding to each type of workpiece material, multiple different temperature test points are first selected. At these test points, ultrasonic cleaning experiments are carried out on standard workpiece samples using ultrasonic power of different strengths. The corresponding ultrasonic power values ​​and cleaning effect index values ​​after cleaning are recorded. Finally, the ultrasonic power with the largest sum of cleaning effect index values ​​is selected as the power value adapted to the sub-range. The most suitable ultrasonic power is found for each temperature sub-range. In the actual cleaning process, the system matches the corresponding optimal ultrasonic power according to the mapping library to drive the ultrasonic transducer to work, maximizing the advantages of ultrasonic cleaning and ensuring high-quality cleaning of workpieces under different working conditions.

[0072] As a specific embodiment of an ultrasonic power control method for a suspended chain cleaning machine, after controlling the ultrasonic transducer to perform ultrasonic cleaning based on the ultrasonic power value, the method further includes:

[0073] The actual output value of the ultrasonic power of the ultrasonic transducer is obtained by a power detector.

[0074] The difference between the actual output value of the ultrasonic power and the set ultrasonic power value is obtained.

[0075] A power deviation threshold is matched based on the power range in which the set ultrasonic power value is located;

[0076] Determine whether the difference is greater than the power deviation threshold; if so, obtain the current power supply voltage value and determine whether it is caused by voltage fluctuation; if so, start the voltage regulator to stabilize the voltage and re-obtain the actual output value of the ultrasonic power; if within the first time period, the difference between the actual output value of the ultrasonic power and the set ultrasonic power value is less than the power deviation threshold, then it is determined that the power deviation has returned to the normal range.

[0077] If it is determined that the problem is not caused by voltage fluctuations, the operating temperature of the ultrasonic transducer is obtained; when the operating temperature is higher than the upper limit of the rated temperature, the speed of the cooling fan of the ultrasonic transducer is increased.

[0078] Specifically, the actual ultrasonic power output value is obtained through a power detector, and the difference between this value and the set ultrasonic power value is calculated. Then, based on the power range of the set power value, a power deviation threshold is matched to determine whether the difference exceeds the threshold, and to monitor whether there are any abnormalities in the ultrasonic power output. If the difference is greater than the threshold, it is further determined whether it is caused by voltage fluctuations. If so, a voltage regulator is activated to stabilize the voltage and the output value is re-detected. This can promptly correct power deviation problems caused by voltage instability, ensuring that the ultrasonic transducer operates at a stable power, thereby ensuring the stability of the cleaning effect. If it is determined that the problem is not caused by voltage fluctuations, the operating temperature of the ultrasonic transducer is then obtained. When the operating temperature exceeds the upper limit of the rated temperature, the speed of the cooling fan is increased to enhance heat dissipation, preventing the ultrasonic transducer from being affected or even damaged due to excessive temperature. This allows it to continuously and stably output appropriate ultrasonic power for cleaning, effectively reducing the adverse effects of abnormal power, excessive temperature, and other factors on the cleaning process.

[0079] As one embodiment of an ultrasonic power control method for a suspended chain cleaning machine, the method further includes:

[0080] Acquire the liquid level height data sent by the liquid level sensor in the cleaning tank;

[0081] The liquid level height data is compared with the lower limit value of the liquid level.

[0082] When the liquid level is lower than the lower limit, the cleaning fluid replenishment device connected to the cleaning tank is activated. The cleaning fluid replenishment device is used to deliver cleaning fluid into the cleaning tank. During the replenishment process, the liquid level sensor continuously monitors the liquid level change. When the liquid level reaches the upper limit, a stop command is sent to the cleaning fluid replenishment device to enable it to replenish the cleaning fluid.

[0083] Specifically, by acquiring the liquid level 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 real-time status of the cleaning fluid in the cleaning tank. When the liquid level is lower than the lower limit, the cleaning fluid replenishment device connected to the cleaning tank is activated in a timely manner, ensuring that there is always sufficient cleaning fluid in the cleaning tank to meet the needs of ultrasonic cleaning, and avoiding situations where the cleaning effect is greatly reduced or even the cleaning operation cannot be carried out normally due to insufficient cleaning fluid. During the replenishment of cleaning fluid, the liquid level sensor continuously monitors the changes in liquid level. Once the liquid level reaches the upper limit, it sends a stop command to the cleaning fluid replenishment device, preventing waste caused by excessive replenishment of cleaning fluid and avoiding problems such as cleaning fluid overflow that may be caused by over-replenishment.
