How to solve the problem of excessively high welding current of ultrasonic wire harness
In fact, there are many factors that cause the high current of the ultrasonic wire harness welding. First, it is necessary to distinguish whether the ultrasonic generator itself is damaged due to the high current, or the ultrasonic load output has a problem causing the high current. So what is the solution? Let’s take you to know more about it by Suzhou Runsheng Precision Machinery Co., Ltd. The details are as follows:
1. The loosening of the screw between the ultrasonic die and the transducer leads to high current. Generally, the method to eliminate it on the machine that has been used for a period of time is to use the special wrench of the ultrasonic die to tighten it to see if the die is not locked.
2. Ultrasonic molds and die heads are damaged or cracked, which usually occur after long-term use or long-term use. The way to eliminate them is to check whether there are cracks on the surface of the die, or install it on other ultrasonic systems for detection.
3. Replace the vibrator of the ultrasonic transducer or the ultrasonic die. If the current is too high after replacing these two parts, this is normal. As long as the ultrasonic frequency is adjusted, this problem can be solved.
