Problems solved by technology
This structure meets the requirements of use to a certain extent, but due to the existence of the elastic body, the structural strength is insufficient, and the welding head deforms greatly when it bears a large welding pressure. Therefore, the existing ultrasonic welding machine is only suitable for small-area workpieces. Unable to meet the needs of high-power large-area ultrasonic resonance welding
In addition, the transducer is mainly composed of ceramic wafers, which are easily damaged under the action of ultrasonic vibration, which affects the service life of the ultrasonic welding machine

Description
technical field [0001] The invention relates to the technical field of ultrasonic welding, in particular to an ultrasonic welding machine. Background technique [0002] Ultrasonic welding technology is widely used in the welding of workpieces such as hard thermoplastics, fabrics and films. Its output power is low, and there is no chemical reaction during the welding process, which can avoid defects such as pores and cracks in traditional welding. [0003] The ultrasonic welding machine mainly includes an ultrasonic generator, a transducer, a horn and a welding head. The ultrasonic generator converts low-frequency alternating current into high-frequency electricity of tens of thousands of hertz, and the transducer converts high-frequency electricity into mechanical motion of the same frequency. , and then the mechanical motion is transmitted to the welding head through the horn device that can change the amplitude, and the welding head transmits the received vibration energy ...
