Focusing On Non Standardized Power Ultrasound Applications By 20Khz Ultrasonic Controller

Description:

Ultrasonic technology has been widely used in the industrial field, and its core component ultrasonic generator, ultrasonic power technology, has also been developed for several generations. From the original tube oscillation circuit - semiconductor electronic oscillator - to the current intelligent digital circuit ultrasonic generator, the ultrasonic oscillation circuit is more and more advanced, reliable and intelligent. The Qianrong series ultrasonic generator has automatic frequency tracking function. Automatically adapt to the frequency of the ultrasonic mold (welding head), no frequency modulation, long-term working frequency will not shift, Qianrong intelligent ultrasonic generator in plastic welding, continuous welding of woven fabric, slitting, edge sealing, shearing, plastic Film sealing and other processes have been widely used.

Ultrasonic generators typically have frequencies of 15, 20, 25, 28, 30, 35, 40 KHz, and the like. The ultrasonic generator has an generating circuit, a feedback circuit, a protection circuit, and an output matching circuit.

Advantages:

• High stability: All-digital integrated circuits, use of US imports of high-performance processors interference, while reducing the number of components, simplify the hardware structure, thereby improving the reliability of the system.
• Automatic frequency tracking: Digital frequency synthesis technology combined with digital phase-locked loop frequency tracking of complex control technology, can eliminate the temperature, static load, machining area, tool wear and other factors drift disadvantages of conventional analog regulator insurmountable, conducive parameter adjustment, easy modification by software, easily adjust the control scheme and achieve a variety of new control strategies.
• Strong output: The use of IGBT power modules plus his excited oscillation circuit structure, the output power is more than 1.5 times that of conventional self-excited circuit.
• Amplitude stepless adjustment: Amplitude can instantly increase or decrease in the adjustment process, also can be micro adjusted, can effectively prevent the perfect size pieces of plastic welding, effectively reducing wear shock, burns and so on. Defective amplitude setting range of 10% to 100%.
• Intelligent three protection and fault alarm: Die-current protection, frequency offset protection, total output is too large to protect. Equipment failure, the generator will stop working, and make the appropriate cause of the malfunction prompts until technician troubleshooting.
• Intelligent closed-loop amplitude control technology to achieve the amplitude adjustment, independent of input supply voltage and load fluctuations affect the amplitude of the output remains constant.
• Two kinds of welding mode switch back and forth, so that a higher precision welding, soldering and better results.
