What is the reason for the instability of the ultrasonic welding machine?
The instability of the ultrasonic welding machine may be caused by the following reasons, please improve the following conditions:
1. Power supply:
Unstable voltage will cause the output power to be too high or too low;
2. Air pressure:
It is necessary to provide clean compressed air at a high enough pressure; the air compressor works intermittently, the same pressure has a small value and a large value, the pressure generally floats from 5kg/cm to 9kg/cm, and the ultrasonic setting pressure It cannot be higher than the small value; in addition, a large number of gas tools and long-distance transportation will affect the stability of the air pressure;
3. When working continuously for a long time, the frequency deviation of the ultrasonic mold will also lead to unstable welding;
4. Machine failure caused by the following reasons:
A The output power of the machine itself is unstable.
B Occasionally overloaded, not detected,
C time control time is short,
D The machine accuracy is not enough, the guide rod is loose, the sensor flange is loose, the column is backward, etc.
5. Plastic materials should not be ultrasonically welded;
6. The ultrasonic wire structure is unreasonable or the plastic structure is unreasonable;
7. The product has multiple molds, and the error is large;
8. The product is affected by the inconsistency of other accessories inside the product.
9. Surface treatment will also affect the welding stability,
