Ultrasonic welding machines can be divided into automatic welding machines, semi-automatic ultrasonic welding machines and manual welding machines according to the level of automation. For modern enterprises, the higher the level of automation, the more favorable the production line of enterprises, so the use of automatic welding machines is one of the future of enterprises. trend.
The principle of ultrasonic welding machine is to generate 20KHz (or 15KHz) high-voltage and high-frequency signals from the generator. Through the energy conversion system, the signal is converted into high-frequency mechanical vibration and applied to the workpiece of plastic products. The temperature transmitted to the interface is increased by the surface of the workpiece and the friction between the molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface is rapidly melted, and then filled in the gap between the interfaces, when the vibration stops, the workpiece simultaneously Cooling and setting under a certain pressure will meet the welding requirements.
The welding method of ultrasonic welding machine is also various, including welding method, rivet welding method, embedding, forming, spot welding, cutting and sealing, etc. It is easy to use and can meet various industries. Different needs. At the same time, the ultrasonic welding machine has a significant production efficiency, good welding quality, environmental protection and energy-saving lamps compared with conventional processes such as gluing, perm ironing and screw fastening. Therefore, ultrasonic welding machines are widely used in medical equipment, auto parts, fishing gear, packaging and other industries.
At present, the country is pursuing sustainable development, which shows that all enterprises should integrate sustainability into their own development while developing. Therefore, the ultrasonic welding machine will be more and more used in the welding industry. Therefore, the development prospect of ultrasonic can be said to be very broad.
