 I Finally Tried Piezoelectric Ceramic Sensor For A Week And This Is What Happened.

                 I Finally Tried Piezoelectric Ceramic Sensor For A Week And This Is What Happened.


At present, the lack of understanding of soldering piezoelectric disc element for the ultrasonic metal welding mechanism is as a solid-phase welding method, or metal "bonding" process, in the welding process, whether piezo elements transducer of the metal-free melting remains to be further studied. There is also the use of ultrasonic waves in material welding, and although the welding effect of piezoelectric ceramics is good, there are still problems in terms of stability, operability, reliability, etc., for the entire system consisting of an ultrasonic generator, an acoustic system and a mechanical system , So the design of the piezo ceramic element sensor acoustic system and the connection between the acoustic system and the specimen are all very important. In addition, the study of piezoresistive pzt ring of ultrasonic vibration on the grain and texture from the perspective of micro-mechanics is also an important direction for future research. Ultrasonic welding is the use of high-frequency piezoceramic disc vibration sensor vibration wave transmitted to the two surfaces to be welded under pressure, so that the two surfaces rubbed each other to form the fusion between molecular layers.Process Research for ultrasonic welding technology materials for Ultrasound Welding Thermoplastics are the ideal material for ultrasonic welding. Because this material does not form an unrecoverable molecular bond when it is pressurized at high temperatures, it can be remixed after reheating. Thermoplastics include non-crystalline plastics and semi-crystalline plastics of two types. The molecular arrangement of non-crystalline polymers is random and has no definite melting point. Non-crystalline polymers transfer energy more efficiently and therefore melt with less energy. The molecular arrangement of semi-crystalline polymers is extremely ordered and has repeating structural features. Have a very definite melting point. Semi-crystalline polymers require high temperatures to melt, absorb large amounts of heat, making them more difficult to weld than semi-crystalline polymers.
