Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ultrasonic products, and particularly relates to an ultrasonic product load characteristic display circuit, method, device and storage medium. BACKGROUND

[0002] An ultrasonic product is a device used in the fields of ultrasonic machining and ultrasonic welding, which converts high-frequency alternating current energy into mechanical energy by using the piezoelectric effect of piezoelectric ceramics to drive the load to vibrate ultrasonically. In the related art, the piezoelectric effect of the ultrasonic product is quite complex. With different voltage frequencies applied to both ends, the piezoelectric ceramics will appear inductive and capacitive alternating changes. Such change parameters are greatly related to the grain structure, shape and size, annealing degree, assembly pressure, load pressure and surface quality of the ceramics. The ultrasonic product often has a complex structure and variable characteristics. The characteristics of different types and different batches of products are quite different. Even the products of the same batch will have some deviations in characteristics due to various problems in the production process.

[0003] The characteristics of the ultrasonic product can be detected by a professional impedance analyzer during the production process. However, in actual use, especially during product installation and debugging, there is no professional test equipment, and the installation and debugging can only be performed by observing the actual processing effect. The installer needs to adjust the state of the ultrasonic product while adjusting the state of the machine equipment. In order to achieve a good load processing effect, the installer can only rely on debugging experience and repeated attempts on the effect of the equipment to make adjustments. Such debugging is often complex and inefficient.

[0056] The present application will be further described below in conjunction with the drawings of the specification and specific embodiments. The described embodiments should not be regarded as limiting the present application, and all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0057] In the following description, "some embodiments" are described, which describe a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0059] The ultrasonic product is used for converting alternating current energy of high frequency into mechanical energy by piezoelectric effect of piezoelectric ceramic, driving the load to do ultrasonic vibration, and thus used for equipment in fields of ultrasonic machining, ultrasonic welding and the like. In the related art, due to the piezoelectric effect characteristics of the ultrasonic product being quite complex, the piezoelectric ceramic appears inductive and capacitive alternating change with different voltage frequencies applied to both ends. The characteristics of the ultrasonic product can be detected by a professional impedance analyzer in the production process, but in actual use, especially during product installation and debugging, there is no professional test equipment, and only the actual processing effect can be observed to install and debug. The installer needs to adjust the state of the ultrasonic product while adjusting the state of the machine equipment, and only by relying on debugging experience and repeated attempts on the effect of the equipment can the better load processing effect be achieved. This debugging is often complex and inefficient, such as improper installation pressure, improper parameter selection, product loosening, product vibration cracking and some details not handled well, and it is difficult to find the problem in the debugging process, resulting in the product not working normally. Therefore, the ultrasonic product is often difficult to install and debug, and requires quite rich installation and debugging experience.

[0060] Therefore, in the embodiments of the present application, an ultrasonic product load characteristic display circuit, method, device and storage medium are provided. By using the circuit, the load characteristics of the ultrasonic product can be converted into data and displayed. By cooperating some simple hardware and software, the voltage and current signals of the power output of the ultrasonic product are sampled, and then the sampling data is processed by a program algorithm, so that a curve can be displayed on the screen according to a specific rule.

[0061] Based on the circuit and method provided in the embodiments of the present application, with the load characteristic curve of the ultrasonic product, the installer can observe the characteristics and state of the ultrasonic product while debugging in the actual debugging process, so as to quickly judge the problem of the ultrasonic product and adjust the problem point. For example, when the phase and impedance of the ultrasonic product appear serious oscillation, it means that the product is probably loosened; the voltage curve amplitude of the ultrasonic product becomes low, which means that the pressure is too large; the curve falls in the middle, which means that the load appears column; and the curve does not fluctuate, which means that the electric box does not output normally. Therefore, by using the method in the embodiments of the present application, the installation and debugging difficulty of the ultrasonic product can be greatly reduced, and the installation efficiency and quality can be improved.

[0062] Next, the ultrasonic product load characteristic display circuit in the embodiments of the present application is explained and described.

[0063] In the embodiment of the present application, the ultrasonic product load characteristic display circuit mainly comprises:

[0064] a sampling circuit, configured to sample a voltage signal and a current signal of a power output of the ultrasonic product;

[0065] Specifically, the sampling circuit can comprise a current transformer and a voltage dividing resistor. The current transformer can be used to sample the current signal of the power output of the ultrasonic product, and the voltage dividing resistor can be used to calculate the voltage signal of the power output.

[0066] an amplification circuit, configured to amplify the voltage signal and the current signal;

[0067] With reference to Figure 1 In the embodiment of the present application, the amplification circuit can be a subtraction operation circuit built by an integrated operational amplifier ADTL082ARZ chip combined with resistors. The circuit can differentially amplify the voltage signal and the current signal obtained by the sampling circuit to obtain voltage signals and current signals with required voltages for subsequent processing. In the embodiment of the present application, the amplification circuit is used, so that very small voltage signals and current signals can be sampled. Therefore, the sampling resistor can only use a small-power SMD resistor to meet the requirements. Compared with the conventional sampling method using a large-power resistor, the structure of the circuit is more compact, and the parameter adjustment is more convenient. Moreover, the amplification circuit in the embodiment of the present application has a differential input mode, which can effectively separate strong and weak electric grounds and prevent strong and weak electric interference.

[0068] a preprocessing circuit, configured to denoise and shape the amplified voltage signal and current signal;

[0069] In some more specific embodiments, the preprocessing circuit of the present application can comprise a filtering circuit, an effective value circuit and a comparison circuit. Please refer to Figure 2 In the embodiment of the present application, the filtering circuit can be an active filter circuit built by an integrated operational amplifier ADTL082ARZ chip combined with resistors and capacitors. The circuit can filter the voltage signal and the current signal amplified by the amplification circuit to obtain regular voltage and current signals. In the embodiment of the present application, the above filtering circuit is used, which can effectively prevent high-frequency interference and jitter, and the circuit parameter adjustment is simple and has a wide adjustment range.

[0070] With reference to Figure 3In the embodiment of the application, the effective value circuit can adopt an integrated operational amplifier ADTL082ARZ chip combined with resistors and diodes to build a precision rectifier circuit. Specifically, the effective value circuit includes an integrated operational amplifier ADTL082ARZ chip, a first diode, a second diode, a third diode, a fourth diode, a thirteenth resistor, a fourteenth resistor, a fifteenth resistor, a sixteenth resistor, a seventeenth resistor, and an eighteenth resistor. The current signal is connected to the second pin of the integrated operational amplifier ADTL082ARZ chip through the fifteenth resistor. The anode of the first diode is connected to the first pin of the integrated operational amplifier ADTL082ARZ chip. The cathode of the first diode outputs a processed current signal. One end of the thirteenth resistor is connected to the second pin of the integrated operational amplifier ADTL082ARZ chip. The other end of the thirteenth resistor is connected to the cathode of the first diode. The anode of the third diode is connected to the second pin of the integrated operational amplifier ADTL082ARZ chip. The cathode of the third diode is connected to the first pin of the integrated operational amplifier ADTL082ARZ chip. The third pin of the integrated operational amplifier ADTL082ARZ chip is grounded through the seventeenth resistor. The fourth pin and the fifth pin of the integrated operational amplifier ADTL082ARZ chip are grounded. The voltage signal is connected to the sixth pin of the integrated operational amplifier ADTL082ARZ chip through the sixteenth resistor. The anode of the second diode is connected to the seventh pin of the integrated operational amplifier ADTL082ARZ chip. The cathode of the second diode outputs a processed voltage signal. One end of the fourteenth resistor is connected to the sixth pin of the integrated operational amplifier ADTL082ARZ chip. The other end of the fourteenth resistor is connected to the cathode of the second diode. The anode of the fourth diode is connected to the sixth pin of the integrated operational amplifier ADTL082ARZ chip. The cathode of the fourth diode is connected to the seventh pin of the integrated operational amplifier ADTL082ARZ chip. The fifth pin of the integrated operational amplifier ADTL082ARZ chip is grounded through the eighteenth resistor. The eighth pin of the integrated operational amplifier ADTL082ARZ chip is connected to a power supply. This circuit can effectively remove the negative half-axis of the sine voltage and current, and the removed part can always maintain 0 potential without the tube voltage drop of the conventional rectifier circuit. The voltage signal and the current signal obtained by the filtering circuit can be converted into a positive voltage signal of 0-3.3V for convenient data processing. In addition, due to the restraint of the operational amplifier, this circuit can avoid the problem of 0.7V tube voltage drop existing in the ordinary diode rectifier circuit, and can ensure that the potential of the rectifier part is 0. Compared with the conventional sampling method of lifting the voltage by 1.65V, this half-wave method can maintain an effective value of 0-3.3V, and the range is twice that of the conventional voltage lifting method, that is, the sampling range is doubled.

[0071] Reference Figure 4 In the embodiment of the application, the comparison circuit can adopt a comparator AD790JRZ chip combined with resistors and diodes to build a zero-crossing comparison circuit,Figure 4 Taking the processing of the voltage signal as an example, the circuit can obtain a voltage signal close to a square wave, and then the voltage signal is shaped by a Schmitt trigger NL17SZ17DFT2G, so that a standard voltage-current square wave signal is obtained. The processing principle of the current signal is similar, and will not be described here.

[0072] A phase discrimination circuit is configured to compare the phases of the voltage signal and the current signal, and output a phase difference signal.

[0073] Reference Figure 5 In the embodiment of the application, the phase discrimination circuit can compare the square waves of the voltage signal and the current signal by using an XOR gate SN74LVC1G86DBVT chip, so as to obtain the part where the voltage and the current are different, that is, the phase difference signal of the voltage signal and the current signal. The width of the waveform represents the specific value of the phase difference. At the same time, the square wave signals of the voltage signal and the current signal are compared by using a flip-flop 74LVC2G74DCUR chip. When the voltage signal leads the current signal, a high-level voltage leading Q signal is obtained. Conversely, when the current signal leads the voltage signal, a high-level current leading Q- signal is obtained. Then, the phase difference signal and the leading signal are compared by using an AND gate SN74LVC1G08DBVR chip. When the voltage signal leads the current signal, the phase difference signal is output by ECAP1. When the current signal leads the voltage signal, the phase difference signal is output by ECAP2.

[0074] A processor is configured to process the voltage signal, the current signal and the phase difference signal, so as to obtain impedance data, power voltage data and power phase difference data of the ultrasonic product.

[0075] A transmission circuit is configured to transmit the impedance data, the power voltage data and the power phase difference data to a display.

[0076] A display is configured to display the impedance data, the power voltage data and the power phase difference data.

[0077] In the embodiment of the application, the processor is configured to process the voltage signal and the current signal, so as to obtain the impedance data and the power voltage data of the ultrasonic product, and is further configured to process the phase difference signal, so as to obtain the power phase difference data. The processor in the embodiment of the application can be composed of any one or more processor chips including MCU single-chip microcomputer, FPGA, CPLD, DSP, ARM, etc. The transmission circuit can be hardware or a communication transmission circuit, and the display can include a display screen and other devices. The specific data processing process in the processor will be described in subsequent method embodiments, and will not be described here.

[0078] It can be understood that the ultrasonic product load characteristic display circuit in the embodiment of the present application is composed of some basic operational amplifier devices, resistors, capacitors, diodes and simple logic circuits, and the whole can use conventional and inexpensive devices, so the implementation cost is very low, and the performance requirement of the device is low. Using the circuit can greatly reduce the installation and debugging difficulty of the ultrasonic product, and is conducive to improving the installation efficiency and quality.

[0079] Referring to Figure 6 , Figure 6 is a flowchart of an ultrasonic product load characteristic display method provided in the embodiment of the present application. The ultrasonic product load characteristic display method can be configured in a terminal device, which can include any one or more of a computer, a personal digital assistant (PDA), a smart voice interaction device, a smart power device or a vehicle-mounted terminal, which is not limited in the present application. Referring to Figure 6 , the ultrasonic product load characteristic display method includes but is not limited to:

[0080] Step 110, acquiring an output period of a power supply of an ultrasonic product;

[0081] Step 120, determining a phase time difference value of a voltage signal and a current signal output by the power supply according to a phase difference signal output by a phase discriminator circuit;

[0082] Step 130, obtaining power supply phase difference data according to a ratio of the phase time difference value and the output period;

[0083] In the embodiment of the present application, when calculating the phase difference data according to the phase difference signal, the output period of the power supply of the ultrasonic product can be acquired first. Specifically, the general ultrasonic power supply is a pure digital power supply, and the accurate frequency f of the output voltage and current can be directly acquired, and the total time T 总 of one power supply output period can be determined according to the frequency f.

[0084] Then, which of the two signal ports of the phase discriminator circuit has a signal can be detected, so that it can be determined whether the voltage signal leads the current signal or the current signal leads the voltage signal. Then, a fixed time can be counted, when the rising edge of the output signal of the phase discriminator circuit is detected, the value M1 at this time is recorded, when the falling edge of the output signal of the phase discriminator circuit is detected, the value M2 at this time is recorded, the difference between M2 and M1 is calculated, multiplied by the fixed time of counting, which is the time width of the phase difference signal, then divided by the total time T of the power supply output period, and then multiplied by 360 degrees to obtain the power supply phase difference data of the product.

[0085] Step 140, under the condition of different power supply output frequencies, a plurality of groups of power supply phase difference data are collected;

[0086] Step 150, determining a plurality of power phase difference coordinate points in a plane with power output frequency as abscissa and power phase difference data as ordinate, connecting each of the power phase difference coordinate points to obtain and display a curve of power phase difference data changing with power output frequency.

[0087] In the embodiment of the application, when the data is displayed, the ultrasonic product can be applied with output signals of different frequencies, and the obtained and processed power phase difference data can be obtained. With the size of the power output frequency as the abscissa and the power phase difference data as the ordinate, a plurality of coordinate points corresponding to the data can be obtained, which can be referred to as power voltage coordinate points. Connecting each power voltage coordinate point can form a characteristic curve of power voltage data changing with power output frequency.

[0088] In some embodiments, the display method of the application further comprises the following steps:

[0089] Obtaining a sampling period of a sampling circuit;

[0090] According to the sampling period and the output period, determining a target sampling number; the target sampling number is greater than or equal to the ratio of the output period to the sampling period.

[0091] In the embodiment of the application, in order to better measure the power output of the ultrasonic product, the number of sampling points needs to be determined, that is, the number of sampling points cannot be too small, otherwise the sampling may not be complete and accurate. Therefore, in the embodiment of the application, the sampling period of the sampling circuit can be determined first, that is, how often data is collected. The sampling period can be denoted as T 采 . Thus, the number of data X = T 总 / T 采 that needs to be sampled in one cycle of the voltage signal and the current signal can be calculated. Y is set as the target sampling number, and it is required that Y is greater than or equal to X regardless of the change of frequency. In this way, the sampled data completely passes through one output period, and can accurately reflect the power output.

[0092] In some embodiments, the display method of the application further comprises the following steps:

[0093] Selecting a target voltage signal of a target processing number of continuous signals from the sampled signals; the target processing number is equal to the ratio of the output period to the sampling period;

[0094] According to the target voltage signal, calculating a voltage effective value, and determining the voltage effective value as the power voltage data;

[0095] Under the condition of different power output frequencies, a plurality of groups of power voltage data are collected;

[0096] A plurality of power voltage coordinate points are determined in a plane with the power output frequency as the abscissa and the power voltage data as the ordinate, and a curve of the power voltage data changing with the power output frequency is obtained and displayed by connecting each of the power voltage coordinate points.

[0097] In the embodiment, when the power voltage data is determined according to the voltage signal, a plurality of voltage signals can be collected, and then a target number of target voltage signals are continuously selected from the voltage signals, and the target number of target voltage signals is equal to the ratio of the output period to the sampling period. Thus, a voltage signal sampled in one period is obtained. Since the sampled voltage signal is a half wave, the average value of the signal multiplied by 2 is the average value of the voltage signal, and then the average value of the voltage signal divided by the conversion coefficient K of the effective value and the average value is the effective value of the voltage signal. In the embodiment, the voltage effective value can be determined as the power voltage data and displayed. Similarly, the current data can also be determined in a similar manner, which will not be described in detail.

[0098] In some embodiments, the display method of the application further comprises the following steps:

[0099] A target number of target voltage signals and target current signals are selected from the signals obtained by sampling, and the target number of target signals is equal to the ratio of the output period to the sampling period.

[0100] The voltage effective value is calculated according to the target voltage signal, and the current effective value is calculated according to the target current signal.

[0101] The impedance data is obtained according to the ratio of the voltage effective value to the current effective value.

[0102] Under the condition of different power output frequencies, a plurality of groups of impedance data are collected.

[0103] A plurality of impedance coordinate points are determined in a plane with the power output frequency as the abscissa and the impedance data as the ordinate, and a curve of the impedance data changing with the power output frequency is obtained and displayed by connecting each of the impedance coordinate points.

[0104] In the embodiment, after the voltage effective value and the current effective value are obtained, the impedance data can be determined according to the ratio of the two. In some embodiments, after the impedance data, the power voltage data and the power phase difference data are obtained, the data can be scaled according to the needs, for example, it can be normalized to 0-255, which is convenient for the installer to quickly understand the load characteristics of the ultrasonic product.

[0105] It can be understood that similarly, the ultrasonic product can also be applied with different frequency output signals, and the obtained impedance data and power supply voltage data are taken as the horizontal coordinate axis and the vertical coordinate, to obtain a plurality of coordinate points corresponding to the data, and the characteristic curve is formed by connecting each coordinate point. Through the characteristic curve, the characteristics of the ultrasonic product can be more intuitively displayed on the screen, and the installer can observe the characteristic curve during debugging, and according to the curve on the screen, the state of the product can be quickly and clearly judged, and then the equipment and machine debugging can be carried out accordingly. Compared with the product without this function, the debugging difficulty can be greatly reduced, and the installation and debugging efficiency can be improved.

[0106] With reference to Figure 7 , the embodiment of the application further discloses a computer device, comprising:

[0107] at least one processor 301;

[0108] at least one memory 302 for storing at least one program;

[0109] When the at least one program is executed by the at least one processor 301, the at least one processor 301 implements the ultrasonic product load characteristic display method embodiment as shown in the method embodiment. Figure 6
