6000W Ultrasonic Power Supply For High-precision automotive interior panel welding

 

Parameter:

Power Supply. Every ultrasonic welder starts with a power supply. The power supply is sometimes referred to as the frequency generator because it takes standard electrical power (usually 115V/220V) at 60 Hz and converts it to the operating frequency of approximately 20 kHz or 20,000 cycles per second. Other output frequencies commonly available range from 15-70 kHz. This high frequency current is then sent through a special cable to the ultrasonic stack.

Product Features:

1. Digital technology:

　　Using DSP chip and D/A converter, using direct digital frequency synthesis technology, a sinusoidal signal generator with controllable frequency and phase is designed and realized. It can eliminate the shortcomings that are difficult to overcome by conventional analog regulators such as temperature drift. It is conducive to parameter setting and variable parameter adjustment. It is convenient to adjust the control scheme and realize a variety of new control strategies through the change of program software. At the same time, it can reduce the number of components and simplify the hardware structure, thereby improving the reliability of the system. Its frequency setting, tracking compensation, amplitude setting, amplified matching output, signal detection and analysis to control its output power, amplitude, and energy;

2. The relationship between power and amplitude:

　　The output power can be changed by changing the amplitude, and the amplitude and power can be linearly changed by electronic amplitude control;

3. Amplitude control:

　　 Amplitude is one of the most important variables in the ultrasonic welding and processing. The company’s unique closed-loop electronic amplitude control technology is used to control the amplitude adjustment, and it is not affected by the fluctuation of the input power supply voltage and load to maintain a constant amplitude output;

4. Power supply voltage adaptability:

The fluctuating power supply voltage will produce inconsistencies in the welding process. The intelligent closed loop amplitude control technology circuit automatically compensates for the power supply voltage change by ±16%, and the amplitude is only changed by ±2%. This function is to achieve repeated welding under unstable working voltage conditions The key to effect;

5. Load characteristics:

　　 The loss generator can maintain a constant amplitude output regardless of the load power, and has a larger power output;

6. Adjust the frequency:

　　 The loss generator has a specific frequency range, and any frequency within the frequency range can be input through the man-machine interface;

7. Frequency automatic scanning/storing:

　　Automatic frequency scanning can save the time of each startup and debugging, and the ultrasonic generator can provide three frequency scanning methods

a. Automatically scan the frequency after power-on and save;

b. Power on and manually scan the frequency and save;

c. The frequency is automatically scanned and stored per unit time to compensate for the frequency drift caused by the heat of the welding head and other factors. This function prevents the high current from impacting the welding head and transducer when the ultrasonic is started, and protects the ultrasonic system;

8.Auto tuning/storing:

　　Ultrasonic transducer suitable for various frequency ranges, automatically adjusts the resonance frequency, and the actual frequency is stored every time the ultrasound stops;

9. Ultrasonic start time:

　　 Ultrasonic start time 10-200mS, suitable for various welding head start characteristics, extending the start time can start the more difficult welding head and extending the stop time to solve the welding head after vibration. For smaller welding heads, the start/stop time can be reduced and the vibration can be started and stopped faster. Can reduce cycle time and increase productivity (start-up characteristics);

10. System protection:

　Frequency offset protection, voltage compensation, amplitude compensation, power compensation, short circuit protection, overload protection, overheat protection;
