20Khz 3000W High Power Digital Generator for Ultrasonic Metal Welding with Frequency Automatic Tracking System

Description:

Ultrasonic power sources are often referred to as ultrasonic sources, ultrasonic generators, and ultrasonic electronics boxes. It is a major component of high power ultrasound systems. Its function is to generate a high-power high-frequency AC signal to drive the ultrasonic transducer to work. The high-quality driving power supply must ensure the stable and safe operation of the high-power ultrasonic system. At the same time, it must monitor the operating frequency, load power, capacitive reactance, impedance and other parameters of the transducer in real time, and can carry out power according to different needs of users. Adjustment of parameters such as amplitude and operation mode.

working principle:

The principle of ultrasonic welding by the ultrasonic digital generator 50/60 Hz current is converted into 15,20,30 or 40 kHz energy, even reach 70khz. The high frequency electrical energy is converted by the transducer is again converted into a mechanical movement of the same frequency, followed by the mechanical motion transmitted to the weld head through a set can change the amplitude modulator means. The welding head will be received by the vibration energy transmitted to the engaging portion of the workpiece to be welded, in the region, the vibration energy is by friction by conversion into heat, the plastic melts. Ultrasonic can not only be used to weld the hard thermoplastic fabrics and films can also be processed.

Frequency automatic tracking technology:

At the atomic point, there is no big difference between the ultrasonic generator used in the metal welding device and the ultrasonic generator used in the plastic welding device. The particularity may be that the welding metal has more important use value and the welding quality is higher. In order to meet the needs of metal welding, it is necessary to use a generator with special properties. The modern ultrasonic generator has an automatic frequency tracking system, and changes in the operation of the mechanical device or electronic components during the welding process cause changes in the vibration frequency. For example, when the welding head and the workpiece are in close contact under the action of the welding static pressure, the vibration frequency will change. If the welding time is too long or the rapid continuous welding causes the material temperature to rise, the vibration frequency will also change. The ultrasonic generator will track the frequency of the vibration system so that the generator and the vibration system are always in resonance. The frequency automatic tracking system can compensate for the change of working state that occurs during the welding process, so that the system is in resonance again and the welding parameters are guaranteed. Stable, the focus is on the stability of the amplitude, which is very important for metal welding
