The ultrasonic transducer in the ultrasonic plastic welding machine is also known as the ultrasonic vibrator . It is one of the core accessories of the ultrasonic welding machine and is also an indispensable part of the ultrasonic welding process.
A brief description of the common problems and maintenance of the vibrator:
The ultrasonic vibrator consists of an ultrasonic transducer and an ultrasonic horn to form an ultrasonic vibration system. The ultrasonic transducer is a device that can convert high-frequency electrical energy into mechanical energy. The ultrasonic horn is a passive device that does not generate vibration itself. It only changes the amplitude of the vibration input by the ultrasonic transducer and then transmits it out, completing the impedance transformation.
maintainance:
The ultrasonic vibrator should be placed in a dry place to prevent the ultrasonic vibrator from getting damp, which will affect normal work. If the ultrasonic vibrator is damp, put it in an oven set at about 100 ℃ and dry it for 2 hours or use a hair dryer to remove moisture until the resistance value is normal; The ultrasonic vibrator is debonded . After the ultrasonic vibrator is debonded , the power output of the ultrasonic power supply is normal , but because the connection between the vibrator and the vibration surface is not good , the vibrator will be burned if it works for a long time . Generally, professional ultrasonic manufacturers should be asked to repair or replace the ultrasonic vibrator if it is debonded.
