Swing type welding device

Abstract

The invention provides a swing type welding device. The swing type welding device comprises a first conversion mechanism, a second conversion mechanism and a welding head. The first conversion mechanism comprises two first transducers, a first amplitude modulator and a first fixing piece, the first amplitude modulator is arranged between the two first transducers, the first amplitude modulator isprovided with a first section part, and the first fixing piece is fixedly arranged at one end of each of the two first transducers and fixedly penetrates through the first section part; the second conversion mechanism comprises two second transducers, a second amplitude modulator and a second fixing piece, the second amplitude modulator is arranged between the two second transducers, the second amplitude modulator is provided with a second section part, and the second fixing piece is fixedly arranged at one end of each of the two second transducers and fixedly penetrates through the second section part; and the welding head is arranged between the output ends of the first amplitude modulator and the second amplitude modulator, wherein an included angle is formed between each amplitude modulator and the corresponding two transducers. In this way, more mechanical energy is converted, and the welding position and angle are increased by swinging the welding head.

Description

technical field [0001] The invention relates to a welder, in particular to a swing type welder. Background technique [0002] The common ultrasonic spot welding machine is a common welding equipment. Its main components include an ultrasonic generator and a transducer, a booster, and a horn (horn, or horn, The energy conversion welding head mechanism composed of three components such as mold) can be driven by a power mechanism such as a pneumatic cylinder, and move up and down within a certain stroke range to pressurize and weld the workpiece. The working principle of the ultrasonic spot welding machine is that the ultrasonic generator generates high-frequency electric energy of about 15KHz to 40KHz, and then the electric energy is converted into mechanical motion (vibration) of the same frequency by the transducer, and then the amplitude modulator converts the mechanical After the movement changes the amplitude, it is transmitted to the welding head. When the welding head ...

AI Technical Summary

Problems solved by technology

[0003] The processing of the workpiece is carried out by driving the welding head up and down for processing and welding. However, due to the vertical and longitudinal lifting processing mode (with gravitational potential energy), the force of the lifting displacement is relatively large. When processing and welding the workpiece , the workpiece (such as two pieces of plastic) is easy to produce dust during processing, which can be cleaned through the cleaning process, but because of this, there is an additional processing step, which makes the process more cumbersome and the manufacturing cost is high

Furthermore, since the welding head is in contact with the workpiece vertically and longitudinally, the welding position and angle are limited, which is less elastic. Correspondingly, the welding area is also limited, which also affects the welding strength.
