Several aspects of improving the working stability of ultrasonic welding machine
When using the ultrasonic welding machine, it is very important to keep the output power stable in order to get qualified products. If the output power can not be stable, the direct result is that the machine can not obtain stable friction heat energy. It can be seen that stable output power is very important, So how can we make the ultrasonic welding machine get stable output power? It mainly needs the following four aspects: the output power of the machine, the expansion ratio of ultrasonic welding head, the pressure source and the voltage source.
There is a formula like this: the actual available power = ultrasonic machine output power + ultrasonic welding head expansion ratio. According to the formula, we can see that for a specific machine, the greater the output power of the machine, the smaller the horn expansion ratio; otherwise, it is the same. We need to get stable output power, which is not to say that the higher the power, the better. We should choose the appropriate power according to the characteristics of the material to maintain its stable output
Pay attention to the coordination of air pressure and voltage. According to experience, such things often happen. When the working hours fail to reach the quality standard, they stop using the voltage and air pressure after work to meet the quality standard. In addition, when many people use the voltage and air pressure at the same time, when the air pressure of the air storage cylinder of the air compressor is too low, the automatic inflation will often lead to product errors.
According to the available resources, the engineer should make reasonable design. The available resources mainly include: existing equipment, product quality requirements, product positioning and material. This is due to some equipment resources
When China is gone, it is necessary to use product design skills to match the existing equipment resources.
Therefore, in order to get stable output power, we need to pay attention to the following aspects
1. The engineer should have a complete understanding of the performance of the machine
2. Understand the required product performance
3. Have a comprehensive understanding of the corresponding relationship between ultrasonic and product welding
4. Use power supply voltage stabilizing equipment and stable compressed air
