Ultrasonic welding machine simple self-maintenance operation

  Ultrasonic welding machine in the work of the generator out of the load alarm is also a common thing, what is the real fault? And what just debug the replacement problem? Next Xiaobian will teach you a trick:

1, often full load detection is normal, and can not operate normally, it may be the internal structure of the welding and other sound energy original changes, resulting in blocked sound energy transmission, here is a very simple method: hand touch method. The normal operation of the welding head or test fixture surface effort when the vibration is very uniform, the hand feels like canary smooth, when the sound energy transmission is blocked, there will be a feeling of bubbles or raw edges with the hand, at this time it is necessary to use the elimination method to remove the problem component. When the generator is abnormal, it can also cause the same situation, because in general, the test transducer input waveform should be smooth sine waveform, when the sine waveform has a peak or abnormal waveform, it can also cause this situation, at this time, you can use another whole acoustic element to replace to identify.

2, ultrasonic full load detection, if the working current is normal, it may be that the ultrasonic welding head has touched the object that should not be touched or the parameter adjustment between the ultrasonic welding head and the welding base is abnormal.

3, when the ultrasonic full load detection is abnormal, we should first observe whether the ultrasonic welding head is cracked, whether the assembly is intact, and then remove the welding head and then carry out the full load detection, remove whether the transducer + test fixture is wrong, and remove it step by step. After filtering out the probability that the transducer + test fixture is abnormal, a new welding head is removed to distinguish.
