What’s ultrasonic generator?
Ultrasonic generator, usually called ultrasonic power supply. Its function is to convert our mains (220V 110V or 380V, 50 or 60Hz) into a high frequency AC signal that matches the ultrasonic transducer. From the form of the amplifying circuit, a linear amplifying circuit and a switching power supply circuit can be used, and the high-power ultrasonic power source generally adopts a circuit form of a switching power supply in terms of conversion efficiency. Linear power supplies also have their own application range, which has the advantage that the circuit can be not strictly required.
Matching allows the operating frequency to change continuously and continuously. From the current situation in the ultrasound industry, ultrasonic generators are mainly divided into self-excited and separate excited power supply.
The principle of the ultrasonic generator is to first generate a signal of a specific frequency by a signal generator, which may be a sinusoidal signal or a pulse signal. This specific frequency is the frequency of the transducer, and is generally applied to ultrasonic in an ultrasonic device. The frequency is 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz,70khz, 100KHz.
The advantages:
1, frequency automatic tracking: digital frequency synthesis technology combined with digital phase-locked loop frequency tracking of composite control technology, can eliminate temperature, static load, processing area, tool wear and other factors drifting conventional analog regulator is difficult to overcome shortcomings, is conducive to parameter adjustment It is convenient to modify the control scheme and implement various new control strategies through the modification of the program software.
2, amplitude infinite adjustment: amplitude can be increased or decreased in the process of adjustment, can also be fine-tuned, effectively prevent the size of plastic parts can be perfectly welded, effectively reduce the penetration, burns, with defective product monitoring function, more suitable for automated use, The setting range of the amplitude is 10%~100%
3, intelligent protection and fault alarm tips: mold current is too high protection, frequency offset protection, total output is too large protection. If the equipment fails, the generator will stop working immediately and prompt the corresponding fault reason until the technician removes the fault.
4. Intelligent closed loop amplitude control technology achieves amplitude adjustment, input voltage fluctuations and load fluctuations to maintain a constant amplitude output.
