Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic equipment control, and specifically to a control management system and method for an ultrasonic cleaner. Background Art

[0002] In the era of pursuing extreme cleanliness and maintaining precision tools, equipment, and precious items, ultrasonic cleaning machines are particularly important. Ultrasonic cleaning machines utilize the cavitation effect generated by ultrasonic waves in liquids, enabling access to tiny gaps that cannot be reached by traditional manual cleaning.

[0003] During the ultrasonic cleaning process, the actual working power and frequency of the ultrasonic cleaning machine may deviate from the preset values. For example, due to electrical or environmental factors, the frequency of the oscillator may shift, and due to changes in equipment load or transducer performance, the power may deviate from the preset value. Therefore, it is necessary to make adaptive adjustments to the ultrasonic cleaning machine during the ultrasonic cleaning process. Summary of the Invention

[0004] The purpose of the present invention is to provide a control management system and method for an ultrasonic cleaner to solve the problems presented in the prior art.

[0005] To achieve the above objective, the present invention provides the following technical solution: A control management method for an ultrasonic cleaner, the method comprising:

[0006] Step S100: Set an evaluation interval for the cleaning parameters of the ultrasonic cleaner and obtain the cleaning parameters set by relevant operators;

[0007] Step S200: Compare the actual value of the ultrasonic power during the operation of the ultrasonic cleaner with the evaluation interval and collect the evaluation results with abnormal evaluation results;

[0008] Step S300: Evaluate the deviation degree of the ultrasonic power from the evaluation interval in the abnormal evaluation results and evaluate the power deviation value per unit time;

[0009] Step S400: When the power deviation value exceeds the preset range, generate a control signal to adjust the ultrasonic power, and verify the power deviation value after each adjustment until it is within the preset range;

[0010] Step S500: Compare the frequency change of the ultrasonic wave before and after the power adjustment, and when a frequency shift occurs after the power adjustment, give an alarm prompt.

[0011] Further, step S100 includes:

[0012] Step S101: Obtain the ultrasonic power and ultrasonic frequency set by the relevant operator when the ultrasonic cleaner performs a certain cleaning task, and record the ultrasonic frequency as the ultrasonic frequency reference value f s ;

[0013] For different cleaning objects, corresponding ultrasonic frequencies need to be set. The cavitation bubbles generated by low-frequency ultrasonic waves are larger and fewer in number, but the energy released during bursting is large, and the cavitation effect is strong, which can effectively remove hard or stubborn dirt. The cavitation bubbles generated by medium-frequency ultrasonic waves are moderate, and it has the ability of both strong cleaning and fine cleaning. The cavitation bubbles generated by high-frequency ultrasonic waves are small and dense, and can better penetrate into small gaps and pores, suitable for fine cleaning;

[0014] Step S102: Set the time period during which the ultrasonic cleaner performs ultrasonic cleaning as the target time period, and divide the target time period into several unit time periods;

[0015] Step S103: Set several evaluation nodes in the unit time period, set the evaluation interval corresponding to the ultrasonic power for each evaluation node, and set the midpoint value of each evaluation interval as the central evaluation value.

[0016] Further, step S200 includes:

[0017] Step S201: Obtain the i-th unit time period in the target time period, and record the number of all evaluation nodes in the i-th unit time period as m;

[0018] Step S202: Collect the ultrasonic power of the ultrasonic cleaner at each evaluation node. When the ultrasonic power is not within the corresponding evaluation interval range, the ultrasonic power at the evaluation node shows an abnormality. Record the evaluation node corresponding to the abnormal ultrasonic power as the abnormal node, and obtain the number of all abnormal nodes in the i-th unit time period as n;

[0019] Step S203: Calculate the power evaluation coefficient w, w = n / m.

[0020] Further, step S300 includes:

[0021] Step S301: Take the midpoint of each evaluation interval as the interval evaluation value, and obtain the ultrasonic power of all abnormal nodes, where the ultrasonic power corresponding to the j-th abnormal node in the i-th unit time period is denoted as p j ; Step S302: Calculate the power difference E in the i-th unit time period i , where, x j represents the interval evaluation value of the corresponding evaluation interval at the j-th abnormal node;

[0022] Step S303: Calculate the interval power evaluation value D for the i-th unit time period i , D i = w×E i ;

[0023] First, obtain the proportion of abnormal nodes among all evaluation nodes, evaluate the abnormality rate of the nodes, further accumulate the deviation values, obtain the cumulative value of the mid-power deviation in the interval, and evaluate the degree of deviation of the interval power from two aspects.

[0024] Further, step S400 includes:

[0025] Step S401: Set the power evaluation interval. When the interval power evaluation value D i is not within the power evaluation interval range, it is determined that the ultrasonic power in the i-th unit time period is abnormal. When the interval power evaluation value D i is within the power evaluation interval range, it is determined that the ultrasonic power in the i-th unit time period is normal;

[0026] Step S402: Set the unit regulation power Δr. When the ultrasonic power in the i-th unit time period is abnormal, if D i > 0, then in the (i + 1)-th unit time period, reduce the ultrasonic power by Δr. If D i < 0, then in the (i + 1)-th unit time period, increase the ultrasonic power by Δr;

[0027] Step S403: After adjusting the ultrasonic power in the (i + 1)-th unit time period, calculate the interval power evaluation value D i+1 for the (i + 1)-th unit time period. When the ultrasonic power in the (i + 1)-th unit time period is abnormal, repeat the regulation steps in step S402;

[0028] Step S404: When the ultrasonic power in the (i + k)-th unit time period corresponding to the k-th adjustment is normal, collect all unit time periods from the i-th unit time period to the (i + k - 1)-th unit time period, denoted as the first monitoring period, and denote the (i + k)-th unit time period as the second monitoring period.

[0029] During the ultrasonic cleaning process, the selection of power and frequency needs to be coordinated with each other. In practical applications, the power and frequency need to be reasonably set according to specific cleaning requirements and workpiece characteristics. Only when the ultrasonic frequency and ultrasonic power are coordinated with each other can a better cleaning effect be achieved. Therefore, when adjusting the ultrasonic power, it is necessary to monitor the ultrasonic frequency; if the frequency shows a deviation after the power adjustment is correct, it indicates that there may be a fault in the ultrasonic cleaner, and relevant technical personnel are required to come and check.

[0030] Further, step S500 includes:

[0031] Step S501: Set the unit frequency f0, the interval endpoint Q1 and the interval endpoint Q2, where Q1 ≤ f s ≤ Q2, Q1 = a × f0, Q2 = b × f0, where a and b are both positive integers and b > a;

[0032] Meanwhile, referring to the initial frequency selection value and the interval endpoints of the frequency interval, evaluate the offset of the ultrasonic wave. When the frequency offset value increases, the ultrasonic cleaning effect will decrease;

[0033] Step S502: Obtain the ultrasonic frequency f at the qth evaluation node in the ith unit time period iq and calculate the frequency offset value g of the ith unit time period i ,

[0034] Step S503: Calculate the frequency offset values corresponding to all unit time periods in the first monitoring period, and denote the average value of the frequency offset values in the first monitoring period as the first frequency reference value U1. Obtain the frequency offset value g of the (i + k)th unit time period i+k and denote it as the second frequency reference value U2;

[0035] Step S504: When U2 > U1, give an alarm prompt to the management personnel of the ultrasonic cleaning machine.

[0036] Furthermore, in step S501, the method for obtaining the unit frequency f0 includes:

[0037] Obtain the length, width and height of the cleaning tank of the ultrasonic cleaning machine, denoted as L, W and H respectively, and calculate the unit frequency f0,

[0038] where c represents the sound speed in the cleaning liquid;

[0039] Regard the ultrasonic cleaning tank as a resonance cavity model. In order to achieve the best cleaning effect, the operating frequency of the cleaning machine should be close to the resonance frequency or its harmonic frequency of the cleaning tank. This means that if the operating frequency of the ultrasonic generator can match f0 or its integer multiple, the cleaning efficiency will be significantly improved;

[0040] In the related technical field, the expression of f0 is an integral part of the frequency expression. 1 / L, 1 / W and 1 / H represent the ratio relationship of the length, width and height, and c / 2π represents the frequency scale. Input dimensionless quantities into the overall expression, and the output result is the frequency.

[0041] To better implement the above method, a control and management system for an ultrasonic cleaning machine is also proposed. The system includes:

The parameter acquisition unit is used to acquire the cleaning parameters set by the relevant operator.

[0044] Furthermore, the power evaluation module includes: a node evaluation unit, an abnormal node management unit, a power evaluation unit, a power difference calculation unit, and an interval evaluation unit. Among them, the node evaluation unit is used to compare the ultrasonic power at the evaluation node with the evaluation interval.

The power evaluation unit is used to calculate the power evaluation coefficient in the unit time period.

The loop control unit is used to check the interval power evaluation value after each adjustment of the ultrasonic power to judge whether to enter a loop.

[0047] Compared with the prior art, the beneficial effects of the present invention are as follows: By monitoring the ultrasonic power, when the ultrasonic power deviates from the preset range, the ultrasonic power is adjusted. Further, by changing the ultrasonic frequency, the working state of the ultrasonic cleaning machine during the power adjustment process is monitored, and warning information is uploaded in a timely manner.
