ultrasonic plastic welder generator 15khz/20khz

The ultrasonic signal generator consists of an ultrasonic power amplifier module which can convert 50/60Hz AC power frequency into ultrasonic frequency for transducer operation and a control module with "system protection monitoring" and "automatic tuning" functions. The control module can cut off the ultrasonic energy when the ultrasonic welding work breaks down, thus providing high safety and reliability for the generator and even the whole welding equipment.

 

1. True automatic frequency tracing (AFC) is suitable for all kinds of welding dies and different design dies. The frequency range of AFC can be traced automatically: + 400HZ (for example, 15KHZ ultrasonic wave, the frequency of the die can be tracked automatically at 14.40-15.20KHZ). Frequency tracking accuracy: + 5HZ

2. Using CPU computer to monitor and control the program speed, adaptability, built-in protection system "system protection monitoring" function will respond to the following situation:

 

IGBT high temperature protection

Excessive pressure causes overload.

The current of ultrasonic generator is too large.

Loosening or other faults of welding head, luffing device or transducer

Generator circuit failure

Cable failure between generator and transducer

Automatic compensation for frequency instability of power supply

 

3. "Auto-tuning" function can make the ultrasonic generator automatically track and compensate the change of welding head frequency. This frequency change occurs when the temperature is too high, the surface of the weld is worn or the impurities are on the weld.

 

4. Built-in automatic constant amplitude system, which can automatically compensate for different pressure changes and voltage fluctuations, and can steplessly adjust the ultrasonic amplitude from 50% to 100% to meet the requirements of different welding workpieces.

 

5. Using IGBT as power amplifier, the reaction speed is faster than that of traditional silicon power transistor, so the protection function is better.
