What are the reasons for the instability of ultrasonic welding machines

2021-07-16

The failure of the machine itself caused:

　　 1. The output power of the machine itself is unstable, sometimes large and sometimes small,

　　2. Occasionally overloaded, not found,

　　3, the time control is long and short,

　　4. The machine precision is not enough, the guide rod is loose, the transducer flange is loose, the column is tilted backward, etc.

　　 What should I do if the ultrasonic welding machine is unstable? Don’t worry, let’s take a look with the editor below.

　　The instability of the ultrasonic welding machine may be caused by the following reasons, please improve the following conditions:

　Air pressure:

Need to provide clean compressed air with high enough pressure; the air compressor works intermittently, and the same pressure has a minimum value and a maximum value. The pressure generally fluctuates from 5kg/cm to 9kg/cm, which is set by ultrasonic The pressure cannot be higher than this minimum value; in addition, a large number of air tools and long-distance transmission will also affect the stability of the air pressure;

　　Surface treatment will also affect welding stability,

　　 For example, the surface of the product is sprayed with UV or rubber oil or other paint, especially the bonding surface of the product is also blocked, which will affect the transmission of ultrasonic waves, thereby affecting the stability of welding.

　　 power supply;

　　 Unstable voltage will cause the output power to increase or decrease;

　　Ultrasonic mold continuous working time for a long time, frequency deviation can also cause welding instability;

　　Plastic materials are not suitable for ultrasonic welding;

　　 The above is the analysis of the reasons for the instability of the ultrasonic welding machine, I hope it will be helpful to everyone.

　　The structure of the ultrasonic line is unreasonable or the plastic structure is unreasonable;

　　 There are more products in one mold, and the error is larger;

　　 The internal assembly of the product is affected by the inconsistency of other accessories,

　　 For example, in a certain electronic product, the battery or circuit board inside is not assembled properly every time due to manufacturing errors, or the plastic shell is needed to withstand the ultrasonic pressure, so that the ultrasonic wave cannot be pressed down.
