Product Description
The welding principle of ultrasonic spot welder is to convert 50/60 Hz current into 15, 20, 30 or 40 kHz electric energy through an ultrasonic generator. The converted high-frequency electric energy is again converted into mechanical motion of the same frequency through the transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude. The welding head transfers the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction to melt the plastic. The short pressure maintained on the workpiece after the vibration stops causes the two weldments to solidify into one body in a molecular link. Generally, the welding time is less than 1 second, and the obtained welding strength is comparable to that of the main body. Ultrasound can be used not only to weld hard thermoplastics, but also to process fabrics and films. The main components of an ultrasonic welding system include ultrasonic generator, transducer/amplitude modulator/welding head triple group, mold and frame.
The characteristics of ultrasonic welding generator:
1. High stability: All-digital integrated circuit, adopts imported high-performance anti-interference processor, at the same time reduces the number of components and simplifies the hardware structure, thereby improving the reliability of the system.
2.Frequency automatic tracking: Digital frequency synthesis technology combined with digital phase-locked loop frequency tracking composite control technology, can eliminate the disadvantages of temperature, static load, processing area, tool wear and other factors that are difficult to overcome by conventional analog regulators , which is conducive to parameter adjustment , Easy to modify through the program software, easy to adjust the control scheme and implement a variety of new control strategies.
3.Powerful output: The application of IGBT power module and the structure of other excited oscillation circuit make the output power more than 1.5 times of traditional self-excited circuit.
4.Intelligent six protection and fault alarm tips: output overcurrent, output overvoltage, input overcurrent, frequency sweep failure, overtemperature protection, and frequency sweep power is too high. If the equipment fails, the generator will immediately stop working and prompt the corresponding cause of the failure until the technician eliminates the failure.
5. Amplitude stepless adjustment: The amplitude can be increased or decreased instantaneously during the adjustment process, and can also be fine-tuned, effectively prevent perfect welding of large and small workpieces, and effectively reduce the phenomenon of shock, burns, and amplitude of defective products.
