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, good maintenance of the transducer is essential. So how should we maintain the ultrasonic transducer?
Maintenance method 1: The panel control display part includes the power switch on the generator panel, the power adjustment potentiometer, and the power output indicator to complete the power switch, power adjustment, output power status display and other functions of the washing machine.
Maintenance method 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 normality of other vibrators. use.
Maintenance method 3: Check the insulation resistance between the 2 and 3 feet to determine the basic situation. Generally, the insulation resistance is required to be greater than 30 megohms. If this insulation resistance value is not reached, usually the transducer is damp, you can put the transducer as a whole (excluding the sprayed shell) into an oven and set it to about 100 ℃ for 3 hours or use a hair dryer to remove moisture to the resistance value. So far.
Maintenance method 4: Perforation on the vibrating surface. Usually, the perforation of the vibrating surface may occur after the full load of the transducer for a year. This is due to the fatigue of the stainless steel plate on the vibrating surface for a long time. The perforation of the vibrating surface indicates the transducer The service life of the device has reached and can only be replaced.
Maintenance method five: vibrator degumming, this will not happen under normal circumstances, the most effective way to avoid vibrator degumming is to pay attention not to hit the vibrating surface during normal use. If the output power of the ultrasonic power supply is normal after the vibrator is degummed, but the vibrator is not well connected to the vibrating surface, the vibration effect of the vibrating surface is not good, and the vibrator may be burnt out after a long time. The processing method of vibrator degumming is more troublesome, and usually it can only be sent back to the manufacturer for solution.
