Ultrasonic transducer
1. Overview Ultrasonic welding transducers have the same starting principle as cleaning transducers, but they are more powerful. It is a high-power acoustic wave supercharger. Usually combined with a concentrating horn and a working head to form a vibration system for plastic welding. To complete ultrasonic welding of plastics, metals and other materials. Ultrasonic welding is the ultrasonic vibration generated by the transducer, which produces the effect of high-frequency friction and heat fusion on the contact surface of the contacted object under pressure, thereby achieving the purpose of welding. Ultrasonic welding transducers are high-power transducers that operate in the gap. Generally, the instantaneous peak power is used to calculate the power of the constant amount. 2. Product
Guosheng ultrasonic welding transducer has the following characteristics:
1. Low resonance impedance;
2. High Q value of machinery;
3. High efficiency of electro-acoustic conversion;
4. Low calorific value;
5. Large amplitude and high velocity.
Notes for transducer installation:
1. Select suitable materials and adjust hardness technology to process and produce horn and working head.
2. Attention should be paid to frequency matching when installing horn or working head, and sound guide glue should be applied at the joint.
3. Use acetone and other solvents to clean the jointed surface during installation.
4. Establish the impedance control technology of the joining process to reduce the joining impedance of the oscillator and improve the electro-acoustic conversion efficiency of the oscillator.
5. Attention should be paid to improving the insulation measures after the installation of oscillator electrodes.
