The factors affecting ultrasonic welding need to be explained from two dimensions, one is the reason for the ultrasonic equipment itself, and the other is the external reasons, such as structural design, injection molding conditions, and the reasons for the ultrasonic welding equipment of plastic materials.
1. Power index
In principle, the ultrasonic welding machine has the attribute of a power index. The power refers to the work output by the ultrasonic welding machine in a unit of time. The greater the power, the greater the output energy of the ultrasonic welding machine. If the power is small, it means that the energy output for the operation is too small. Usually, the power selection can be based on the attribute requirements of the operation object to select the required power size.
2. Welding air pressure.
The air pressure can be controlled by pressure regulation, and the pressure regulating valve is the functional component responsible for controlling the air pressure. In the welding operation, the greater the pressure, the greater the energy to the workpiece. If the pressure is too large, it will cause damage to the workpiece or excessive welding and cause adverse effects. If the pressure is too small, it will affect the energy output stability of the welding operation. Causes the bad effect of virtual welding. The working pressure acts on the workpiece, which can improve the plasticity of the working workpiece and facilitate the transmission of energy in the working workpiece.
3. Ultrasonic frequency.
Ultrasound is the principle of an ultrasonic welding machine. Ultrasonic frequency even if the ultrasonic vibration wave frequency, the object vibrates to make a sound, and the wave frequency exceeds the range of human ear capture. It is defined as an ultrasonic wave. The wave frequency is an important attribute that determines the ultrasonic wave. , The more energy output by the welding head welding operation, and the lower the wave frequency, the smaller the output energy of the welding operation. Usually, the frequency attribute of the principle of the ultrasonic welding machine is fixed, and the selection can be based on the attributes of the operation object. to make a selection.
4. The influence of amplitude
The amplitude can usually be controlled by an amplitude modulator. The amplitude is not only the amplitude of the ultrasonic wave frequency but also another factor that affects the ultrasonic energy. The larger the amplitude, the greater the energy output of the welding head welding operation.
5. Welding time
The influence of the time of the welding operation principle on the welding operation, with the different welding times, the longer the welding time, the more energy obtained by the welding operation, and the shorter the welding time, the less energy obtained by the welding operation.
