Description

Technical Field

[0001] This utility model relates to a welding device, and more particularly to an ultrasonic welding device. Background Technology

[0002] Examples include Chinese Patent No. CN110598366B, "Design Method of Longitudinal-Torsion Composite Vibration Ultrasonic Amplifier Rod Based on Frequency Coupling," and Chinese Patent No. CN213002683U, "An Ultrasonic Tool Holder Without a Sealing Nut." Please refer to patent No. CN110598366B. Figure 2 It incorporates helical or oblique grooves on the amplitude transformer (i.e., the modulator) to convert the longitudinal vibration acting on the amplitude transformer into torsional vibration. Please refer to case CN213002683U. Figure 1 It has several spiral vibration guide grooves spaced apart on the outer periphery of the amplitude rod (i.e., amplitude modulator). The vibration guide grooves can convert part of the longitudinal vibration of the mechanical vibration into torsional vibration, thereby forming a combined longitudinal and torsional mechanical vibration.

[0003] However, both CN110598366B and CN110598366B only allow for the installation of a single transducer. Therefore, although they can convert part of the longitudinal vibration of the mechanical vibration into torsional vibration, thereby forming a combined longitudinal and torsional mechanical vibration, they still cannot significantly increase the mechanical vibration.

[0004] Therefore, how to improve the aforementioned deficiencies is the technical challenge that the creators of this case sought to solve. Utility Model Content

[0005] In view of the conventional application, the purpose of this utility model is to solve and improve the problems and deficiencies of the conventional application by providing a welding device.

[0006] This utility model provides a welding device, which includes: a welding head having a welding surface; and an amplitude modulator disposed on one side of the welding head, the amplitude modulator including an amplitude modulator body, a connecting part and at least one input part, the two ends of the connecting part being connected to the amplitude modulator body and the at least one input part respectively, and the connecting part being spiral in shape.

[0007] The input section of the amplitude modulator is equipped with a transducer, and the transducer is inclinedly connected to the input section.

[0008] The input section of the amplitude modulator is provided with a transducer, and the transducer is vertically connected to the input section.

[0009] The connecting part is a spiral that rotates counterclockwise.

[0010] The connecting part is a clockwise rotating spiral.

[0011] Therefore, the amplitude modulator is provided with a spiral-shaped connecting part, which can convert part of the mechanical vibration acting on the amplitude modulator from longitudinal vibration to torsional vibration, that is, convert the longitudinal wave into a transverse wave, forming a combined longitudinal and torsional mechanical vibration. Moreover, the at least one input part can be multiple input parts, which can be equipped with multiple transducers to concentrate and transmit the mechanical vibration provided by each transducer to the welding head, thereby enhancing the amplitude of the welding head and achieving the purpose of improving welding efficiency.

[0018] To facilitate a concise understanding of the other features, advantages, and effects of this utility model, the following detailed description, in conjunction with the accompanying drawings, is provided:

[0019] Please see Figure 1 As shown, this utility model provides a welding device, the first embodiment of which includes:

[0020] A welding head 1, which has a welding surface 11.

[0021] An amplitude modulator 2 is disposed on one side of the welding head 1. The amplitude modulator 2 includes an amplitude modulator body 21, a connecting part 22, and at least one input part 23. The two ends of the connecting part 22 are respectively connected to the amplitude modulator body 21 and the at least one input part 23, and the connecting part 22 is spiral-shaped. The amplitude modulator 2 is a component of the ultrasonic welding machine, and its main function is to increase the amplitude of mechanical vibration through different shapes. The input part 23 of the amplitude modulator 2 is provided with a transducer 3, and the transducer 3 is vertically connected to the input part 23. The transducer 3 can be a piezoelectric ceramic transducer to provide high-frequency mechanical vibration.

[0022] Please see Figure 2 The second embodiment shown is similar to the first embodiment, and the similarities will not be described again here. However, there are still differences between the second and first embodiments. The difference is that the input section 23 of the amplitude modulator 2 is provided with the transducer 3, and the transducer 3 is obliquely connected to the input section 23. In the first embodiment, the mechanical vibration of the transducer 3 is transmitted vertically to the amplitude modulator 2; in the second embodiment, the mechanical vibration of the transducer 3 is transmitted obliquely to the amplitude modulator 2.

[0023] Please see Figure 3 The third embodiment shown is similar to the first embodiment, and the similarities will not be described again here. In the third embodiment, the connecting part 22 is a counterclockwise rotating spiral. However, the third embodiment is still different from the first embodiment. The difference is that the number of input parts 23 of the amplitude modulator 2 is adjusted to four according to the implementation requirements, and the number of transducers 3 is also four.

[0024] Please see Figure 4 The fourth embodiment shown is similar to the third embodiment, and the similarities will not be described again here. However, there are still differences between the fourth embodiment and the third embodiment. The difference is that in the fourth embodiment, the connecting part 22 is a clockwise rotating spiral.

[0025] Please see Figure 5 As shown, the four transducers 3 provide high-frequency mechanical vibrations. The mechanical vibrations are transmitted sequentially to the connecting part 22 and the amplitude modulator body 21 via the input part 23 connected to each transducer 3. The amplitude modulator 2 then concentrates the mechanical vibrations and transmits them to the welding head 1, so that the welding surface 11 of the welding head 1 can be used to weld the workpiece.

[0026] Therefore, the amplitude modulator 2 is provided with a spiral-shaped connecting part 22, which can convert part of the mechanical vibration acting on the amplitude modulator 2 from longitudinal vibration to torsional vibration, that is, convert the longitudinal wave into a transverse wave, forming a combined longitudinal and torsional mechanical vibration. Moreover, the at least one input part 23 can be a plurality of input parts 23, for setting the plurality of transducers 3, and concentrating the mechanical vibration provided by each transducer 3 to the welding head 1, thereby enhancing the amplitude of the welding head 1 and achieving the purpose of improving welding efficiency.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, any equivalent changes in shape, structure or combination made without departing from the spirit and scope of the present utility model should be covered within the protection scope of the present utility model.
