Robotic Ultrasonic Spot Welding For Car Interior Components
Ultrasonic welding principle of spot welding machine is 20 KHZ (or 15 KHZ) generated by the generator of high voltage, high frequency signal, can by changing the system, the signal is converted to high-frequency mechanical vibration, and on the plastic workpiece, through the surface and inner friction between the molecules and make the transfer to the interface temperature, when the temperature reaches the melting point of the workpiece itself, the workpiece interface rapidly melting, and then fill in the space between the interface; When the vibration stops, the workpiece is cooled and shaped at a certain pressure to achieve perfect welding.
1. Electronic products: recording, cassette case and core wheel, magnetic disc shell, mobile phone panel and rectifier transformer, switch socket, remote control, electronic mosquito bat, imitation and false bottle cover, etc.;
2. Household electrical appliances: electronic clock, electric blower and drum, steam iron water tank, electric kettle air bag, computer, etc.;
1. Ultrasonic spot welder greatly reduces the processing time, and the combination of plastics can be completed in a few milliseconds.
2. The process is clean, stable and reliable with the application of ultrasonic wave.
3. Low energy consumption, ultrasonic energy will be consumed only in the precise area where welding is required, and there is no need for preheating and heat preservation during efficient and economical operation.
4. The use of ultrasound does not generate excess heat without the use of expensive and easily polluting AIDS, such as adhesives, fasteners or adhesives.
