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.
