When the ultrasonic wave acts on the thermoplastic plastic contact surface, it will generate tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration with a certain amplitude will transmit the ultrasonic energy to the welding area through the upper weldment. Because the welding area is two The acoustic resistance at the welding interface is large, so local high temperature will be generated. In addition, due to the poor thermal conductivity of the plastic, it cannot be distributed in time for a while, and it gathers in the welding area, causing the contact surface of the two plastics to melt rapidly, and after a certain pressure is applied, they are fused into one. When the ultrasonic stops, let the pressure continue for a few seconds to make it solidify and shape, thus forming a strong molecular chain, achieving the purpose of welding, and the welding strength can be close to the strength of the raw material. The quality of ultrasonic plastic welding depends on three factors: the amplitude of the transducer's welding head, the applied pressure and the welding time. The welding time and welding head pressure can be adjusted, and the amplitude is changed by the transducer and the welding head.
Rod decision. There is an appropriate value for the interaction of these three quantities. When the energy exceeds the appropriate value, the melting amount of the plastic is large and the welded material is easy to deform; if the energy is small, it is not easy to weld firmly, and the applied pressure cannot be too large. The optimal pressure is the product of the side length of the welded part and the optimal pressure per 1mm of the edge
1. Automobile: (Traffic industry) Ultrasound can be controlled by computer programs to weld large and irregular workpieces such as bumpers, front and rear doors, lamps, brake lights, etc. With the development of high-grade roads, more and more reflectors are welded by ultrasonic.
2. Home appliances: Through appropriate adjustments, it can be used for: portable fluorescent lampshade, steam ironing door, TV shell, recording, sound machine transparent panel, power rectifier, TV shell screw fixing seat, mosquito-reducing lamp shell, washing machine dehydration tank, etc. Sealed, strong and beautiful household appliances.
3. Packing: The sealing of the hose and the connection of the special packing belt.
4. Toy industry: The use of ultrasonic technology makes products clean, efficient and firm, and eliminates the use of screws, adhesives, glues or other auxiliary products, reduces production costs, and greatly enhances the competitiveness of enterprises in the market.
5. Electronics: The use of automation program design enables users to achieve large-scale production while ensuring product quality requirements.
6. Other commercial uses: From communication equipment, computer industry, printing equipment to audio-visual products, etc., ultrasonic equipment can be used.
