How To Care For Ultrasonic Transducers?
The ultrasonic vibration generated by the ultrasonic transducer transmits the ultrasonic vibration energy to the welding area through the upper weldment, which is the core device of the ultrasonic welding machine. Therefore, in order to prolong the service life of the ultrasonic welding machine, it is essential to maintain the transducer well. So how should we maintain the ultrasonic transducer?
1.The panel control display part includes the power switch on the generator panel, the power adjustment potentiometer, the power output indicator, etc., to complete the power switch, power adjustment, output power status display and other functions of the cleaning machine.
2.The transducer vibrator is on fire and the ceramic material is broken. It can be checked with the naked eye and a megohmmeter. Generally, as an emergency measure, individual damaged vibrators can be disconnected without affecting the normal operation of other vibrators. use.
3.Check the insulation resistance value between feet 2 and 3 to judge the basic situation. Usually, the insulation resistance is required to be greater than 30 megohms. If the insulation resistance value cannot be reached, usually the transducer is damp. You can put the whole transducer (excluding the plastic-sprayed casing) into the oven and set it at about 100 °C for 3 hours or use a hair dryer to remove moisture to the resistance value. until normal.
4.Perforation of the vibration surface. Usually, the perforation of the vibration surface may occur after the transducer is used for a year at full load. This is due to the long-term high-frequency vibration fatigue of the stainless steel plate of the vibration surface. The perforation of the vibration surface indicates that the transducer The service life has expired and can only be replaced.
5.The vibrator is degummed. This situation does not occur under normal circumstances. The most effective way to avoid degumming of the vibrator is to pay attention not to impact the vibrating surface during normal use. If the output power of the ultrasonic power supply is normal after the vibrator is degummed, but the vibration effect of the vibrating surface is not good due to the poor connection between the vibrator and the vibrating surface, the vibrator may be burned out after a long time. The treatment method of vibrator degumming is more troublesome, and usually it can only be sent back to the manufacturer to solve it.
