First, the basic principle of ultrasonic welding machine
The ultrasonic welding machine mainly uses the vibration energy and heat generated by high-frequency ultrasonic waves on the surface of plastics, metals or other materials to make two or more welded parts tightly bonded together in a short time. Ultrasonic welding machines are usually composed of ultrasonic generators, transducers and welding heads. The ultrasonic generator converts direct current into high-frequency alternating current, drives the transducer to generate high-frequency vibration, and then transmits it to the welding head, so that the welded parts generate high-intensity friction and heat at the contact point of the welding head to realize welding.
2. Advantages of ultrasonic welding machine
Good welding effect: Ultrasonic welding can make the welded parts tightly combined in a short time, with high weld strength, beautiful appearance and stable welding quality.
Fast welding speed: Ultrasonic welding is extremely fast and more efficient than traditional welding methods.
Small heat impact: The heat generated by ultrasonic welding is concentrated, which has little impact on the tissue around the welded part, and can effectively protect the welded part from heat damage.
Low requirements for welded parts: Ultrasonic welding does not require special pretreatment of welded parts, and is easy to operate and low in cost.
No pollution: Ultrasonic welding does not need to use any chemical substances and has no pollution to the environment.
3. Application field of ultrasonic welding machine
