How should we solve the problem of ultrasonic overload and the abnormal noise of the ultrasonic horn(sonotrode)?

If you have purchased an ultrasonic welding machine, then you must have encountered two phenomena of ultrasonic overload and ultrasonic horn(sonotrode) abnormal noise. If you have not encountered it yet or you will become an ultrasonic welding machine user, then you must carefully look at the following, Because these are two common faults in the operation of ultrasonic welding machines:

　1st,Ultrasonic overload:

 

　　 1. When an overload alarm occurs, first check whether the operation power supply is normal, and determine whether it is an abnormal power supply.

　　 2. If the power supply is normal, perform a no-load operation test to carefully observe whether the ultrasonic horn(sonotrode) is loose or cracked.

　　 3. If there is no obvious abnormality in the ultrasonic horn(sonotrode), remove the welding head and continue the no-load operation test to confirm whether the amplitude modulator and the transducer are abnormal. If it is ruled out, test the ultrasonic horn(sonotrode) again.

　　 4. If no abnormality can be found in the no-load running test, touch the welding head amplitude modulator with your hand to check whether the amplitude is uniform. If the amplitude fluctuates abnormally, replace the acoustic energy component of the ultrasonic welding machine for testing.

　　 Seond, The ultrasonic horn(sonotrode) makes an abnormal noise:

　　 When the ultrasonic horn(sonotrode) makes abnormal noises, check whether the ultrasonic horn(sonotrode)screws are loose and whether there are cracks .
