What’s ultrasonic generator?
Ultrasonic generator, usually called ultrasonic power supply. Its function is to convert our mains (220V 110V or 380V, 50 or 60Hz) into a high frequency AC signal that matches the ultrasonic transducer. From the form of the amplifying circuit, a linear amplifying circuit and a switching power supply circuit can be used, and the high-power ultrasonic power source generally adopts a circuit form of a switching power supply in terms of conversion efficiency. Linear power supplies also have their own application range, which has the advantage that the circuit can be not strictly required.
Matching allows the operating frequency to change continuously and continuously. From the current situation in the ultrasound industry, ultrasonic generators are mainly divided into self-excited and separate excited power supply.
The principle of the ultrasonic generator is to first generate a signal of a specific frequency by a signal generator, which may be a sinusoidal signal or a pulse signal. This specific frequency is the frequency of the transducer, and is generally applied to ultrasonic in an ultrasonic device. The frequency is 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz,70khz, 100KHz.

The ultrasonic signal generator is composed of an ultrasonic power amplifier module that can convert 50/60 Hz industrial frequency alternating current into super audio frequency for the transducer to work, and a control module with "system protection monitoring" and "auto-tuning" functions. The control module can cut off the ultrasonic energy when the ultrasonic welding work fails, thus providing extremely high safety and reliability for the generator and the entire welding equipment.
1. Really automatic frequency tracking (AFC) adapts to various sizes of welding molds and different design molds. The frequency range of automatic tracking: ±400HZ (according to 15KHZ ultrasonic for example, the mold frequency can be used for automatic frequency tracking at 14.40-15.20KHZ). Frequency tracking accuracy: ±5HZ
2. Adopt CPU computer to monitor each program with fast speed, strong adaptability, built-in various
protection systems, "system protection monitoring" function will respond to the following situations:
u _ Excessive pressure leads to overload
u Ultrasonic generator current is too large
u _ Welding head, horn or transducer loose or other failure
u _ Generator circuit failure
u _ Faulty cable between generator and transducer
u Automatic compensation for unstable power supply frequency
3. The "automatic tuning" function enables the ultrasonic generator to automatically track and compensate
for changes in the welding head frequency. When the temperature is too high, the surface of the welding
head is worn or there is debris on the welding head, this frequency change will occur.
4. Built-in fully automatic constant amplitude system, which can automatically compensate for different air pressure changes and voltage fluctuations, and can adjust the ultrasonic amplitude from 50% to 100% steplessly to meet the requirements of different welding workpieces.
5.Using IGBT for power amplification, the response is fast, which is more than 100 times faster than
the traditional silicon power tube, so the protection function is better.
Voltage: 198-242VAC (50 / 60Hz), the output will be much weaker when AC110V input, need some adjustment, direct use is almost only used for cutting applications.
Volume: 384mm * 240mm * 110mm
Color: light gray
Automatic frequency tracking: The system automatically tracks the resonance frequency of the welding horn. Compensate for detuning caused by heat and other reasons.
Digital frequency control: The operating frequency is digitally controlled by the microcontroller.
Digital amplitude setting: This feature allows users to set precise amplitudes according to application requirements, which provides a larger range and repeatability of settings than analog systems.
The amplitude can be adjusted in a large range: 1% ~ 100% continuously adjustable, which is different from the shortcomings of traditional generators that are difficult to work with low amplitude.
High-speed micro-controller: The internal micro-controller operates at a frequency of up to 168MHz, which can accurately and timely control the working conditions.
Control and sampling interval of 0.5 milliseconds: 2000 times of sampling and control for welding process per second.
Color touch screen display: Through the color screen and touch, friendly and easy-to-use human-computer interaction is realized, and the experience is better.
Coexistence of buttons and touch: common functions can provide better interaction through buttons. Among them, the buttons use silicone keys, which have a better feel.
Operating language: The user can select the applicable language in the start screen: currently only supports English and Chinese.
Slant start: Ultrasonic energy supply and welding horn start at the most suitable ascent speed to reduce the electromechanical pressure of the system.
Vibration after welding: The user can start the ultrasonic after the welding and pressure holding process is finished, and the workpiece sticking to the welding horn will be shaken off.
Welding quality monitoring: user-definable process alarm. When it is outside the range of user-defined defective products, the system will generate an alarm to remind
