Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic power supply production, in particular to an ultrasonic power supply correction system. Background Art

[0002] The basic function of ultrasonic power supply is to convert electrical energy into high-frequency AC signals to drive ultrasonic transducers. These signals can be sinusoidal or pulse signals, and their electrical signal output power and amplitude need to match the transducer to achieve optimal energy conversion efficiency and equipment performance. For the detection and correction of ultrasonic power supply, since ultrasonic power supply must work with ultrasonic transducer, transducer is a mechanical vibration, and its load characteristics are extremely unstable, which greatly interferes with detection and correction and affects the correction accuracy.

[0003] Therefore, in view of the deficiencies in the prior art, the utility model designs an ultrasonic power supply calibration system to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the utility model. Utility Model Content

[0006] To achieve the above-mentioned purpose and other related purposes, the technical solution provided by the utility model is: an ultrasonic power supply calibration system for detecting and calibrating the output power and amplitude of the electrical signal of the ultrasonic power supply, comprising a load module, a signal collection module and a control module in sequence, wherein:

[0007] The load module includes a pure resistor, which replaces the ultrasonic transducer as the circuit load to improve the stability of the circuit load and facilitate the adjustment of the output power and amplitude of the electrical signal of the ultrasonic power supply; a heat dissipation component is provided at the pure resistor, which is used to dissipate the heat generated by the high-frequency voltage of the pure resistor in time to avoid damage to the pure resistor due to overheating; the pure resistor and the ultrasonic power supply form a load circuit through a cable;

[0008] The signal collection module is arranged on the load circuit, and is used to collect the power and amplitude of the electric signal output by the ultrasonic power supply on the load circuit, and transmit it to the control module;

[0009] The output end of the control module is connected to the output end of the signal collection module, and the output end of the control module is connected to the ultrasonic power supply. The control module cyclically compares the power and amplitude of the electrical signal collected by the signal collection module with the standard value, and adjusts the ultrasonic power supply according to the difference value to make the power and amplitude of the electrical signal output by the ultrasonic power supply consistent with the standard value.

[0010] The preferred technical solution is: the heat dissipation component includes a fixing frame, on which at least one group of heat sinks are provided, the heat sinks are connected to the pure resistor, the heat dissipation area is increased by the heat sinks, and the heat dissipation efficiency of the pure resistor is accelerated.

[0011] The preferred technical solution is: a cooling fan is also provided at the heat sink to increase the air flow rate at the heat sink, avoid heat concentration, and improve the heat exchange efficiency between the heat sink and the air.

[0012] The preferred technical solution is: the heat sink is an aluminum alloy heat sink, which increases the thermal conductivity of the heat sink and thus improves the heat dissipation efficiency.

[0013] The preferred technical solution is: rollers are provided at the bottom of the fixing frame to facilitate the movement of the heat dissipation component.

[0014] The preferred technical solution is: the control module and the ultrasonic power supply use 485 bus communication, and the 485 bus communication uses two signal lines for differential signal transmission. This method can effectively offset external interference and improve the signal's anti-interference ability.

[0015] The preferred technical solution is: the number of pure resistors is one group or more, the pure resistors are connected in series on the load circuit, and the load module is set to have multiple pure resistors connected in series, which helps to dissipate heat from the resistors and avoid changes in the resistance value due to excessively high temperature.

[0016] Due to the application of the above technical solution, the ultrasonic power supply calibration system provided by the utility model has the following advantages over the prior art:

[0017] (1) Using pure resistance instead of ultrasonic transducer as circuit load improves the stability of the load, thereby improving the detection and correction accuracy of the ultrasonic power supply. After correction by the ultrasonic power supply correction system, the difference between the output accuracy and the standard value is ≤1%.

[0018] (2) The control module continuously monitors and cyclically corrects the output electrical signal of the ultrasonic power supply based on the data collected by the signal collection module, thereby ensuring the output stability of the ultrasonic power supply.

[0019] (3) A heat dissipation component is set at the pure resistor to prevent the generated heat from affecting the resistance value of the pure resistor. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example:

[0027] like Figure 1 As shown, the utility model discloses an ultrasonic power supply correction system for detecting and correcting the output power and amplitude of the electrical signal of the ultrasonic power supply 4, including a load module 1, a signal collection module 2 and a control module 3. The main components of the utility model are described in detail below:

[0028] like Figure 1 and Figure 2 As shown, the load module 1 includes a pure resistor 11, and a heat dissipation component 12 is provided at the pure resistor 11. The heat dissipation component 12 includes a fixed frame 12a, and six groups of heat sinks 12b are provided on the fixed frame. The heat sink 12b is made of aluminum alloy; the heat sink 12b is connected to the pure resistor 11; and a roller 12c is provided at the bottom of the fixed frame 12a for moving the fixed frame 12a. The pure resistor 11 and the ultrasonic power supply 4 form a load circuit through a cable, and the pure resistor 11 serves as a stable load of the load circuit. It should be noted that the above structure is only exemplary and not restrictive. In this embodiment, the number of pure resistors 11 is one, but in other embodiments, multiple pure resistors 11 connected in series can be used as circuit loads; at the same time, in this embodiment, the heat sink 12b is the main heat dissipation mechanism, but in other embodiments, a heat dissipation fan can also be added at the heat sink 12b to enhance the heat dissipation capacity.

[0029] like Figure 1 and Figure 2 As shown, the signal collection module 2 is arranged on the load circuit, and is used to collect the power and amplitude of the electrical signal output by the ultrasonic power source 4 on the load circuit.

[0030] like Figure 1 and Figure 2 As shown, the output end of the control module 3 is connected to the output end of the signal collection module 2, and the output end of the control module 3 is connected to the ultrasonic power supply 4, for cyclically comparing and correcting the output parameters of the ultrasonic power supply 4 according to the signal feedback of the signal collection module 2, wherein the control module 3 and the ultrasonic power supply 4 communicate using a 485 bus.

[0031] refer to Figure 1 and Figure 2 As shown, the principle of the utility model is as follows: during calibration, the ultrasonic power supply 4 is connected to the calibration system. After the calibration starts, the ultrasonic power supply 4 and the pure resistor 11 form a load circuit. In the pure resistor circuit, the relationship between current and voltage directly follows Ohm's law, which is convenient for detection and calibration; at the same time, the heat dissipation component 12 arranged at the pure resistor 11 quickly dissipates the heat emitted by the pure resistor 11 to avoid heat accumulation causing the resistance value of the pure resistor 11 to change; after the circuit is connected, the signal collection module 2 continuously collects the power and amplitude of the electric signal output by the ultrasonic power supply 4 and feeds the information back to the control module 3. The control module 3 compares the power and amplitude of the electric signal output by the ultrasonic power supply 4 with the standard value, and automatically adjusts the ultrasonic power supply 4 according to the comparison difference value, so that the power and amplitude of the electric signal output by the ultrasonic power supply 4 are consistent with the standard value.
