Description

Amplitude modulator structure for ultrasound

This work is about an amplitude modulator structure, especially an amplitude modulator structure for ultrasonic waves.

For example, a "welding head structure" in the Republic of China Patent No. M611684 includes a transducer; an amplitude modulator connected to one side of the transducer; a cross-shaped conductive mold, one top end of the cross-shaped conductive mold is connected to the amplitude modulator; and at least one welding head, each of which is disposed at the other top ends of the cross-shaped conductive mold.

However, because in Figure 1 of Case No. M611684, there is only one amplitude modulator on one side of the welding head, and the amplitude modulator is equipped with a transducer, when welding large workpieces, the amplitude of the welding head may not be sufficient to complete the welding operation in one go, and it needs to be implemented in multiple times, resulting in low welding efficiency and poor welding quality.

Therefore, how to improve the above deficiencies is the technical difficulty that the creator of this case wants to solve.

In view of the above usage, this creation aims to solve and improve the problems and deficiencies in usage.

This invention provides an amplitude modulator structure for ultrasonic waves, which includes: a welding head, which is provided with a plurality of welding surfaces; and two amplitude modulators, which are respectively arranged on both sides of the welding head, and the two amplitude modulators are respectively provided with at least two input parts.

The two modulators have the same appearance and are symmetrically arranged on both sides of the welding head.

Among them, the input part of the two amplitude modulators is provided with a transducer.

Thus, the input parts of the two amplitude modulators can be provided with the transducer respectively, and the mechanical vibration provided by the transducer is transmitted to the two amplitude modulators through the input parts, and then the two amplitude modulators respectively transmit the mechanical vibration to the welding head in a concentrated manner, thereby enhancing the amplitude of the welding head and achieving the purpose of improving welding efficiency.

In order to make it easier for you, the reviewer, to understand the other features, contents and advantages of this work and to make the effects it achieves more obvious, this work is accompanied by pictures and explained in detail as follows:

Please refer to Figures 1 and 2. This invention provides an amplitude modulator structure for ultrasound, and its first embodiment includes:

A welding head 1, the welding head 1 is provided with a plurality of welding surfaces 11. The welding head 1 may be generally cross-shaped in appearance.

Two amplitude modulators 2 are respectively arranged on both sides of the welding head 1, and the two amplitude modulators 2 are respectively provided with at least two input parts 21. The two amplitude modulators 2 are a component of the ultrasonic welding machine, and their main function is to increase the amplitude of mechanical vibration through different shapes.

The two amplitude modulators 2 have the same appearance and are symmetrically arranged on both sides of the welding head 1. The input parts 21 of the two amplitude modulators 2 are respectively provided with a transducer 3. The transducer 3 can be a piezoelectric ceramic transducer to provide a high-frequency mechanical vibration.

In FIG. 1 and FIG. 2 , the number of input parts 21 of the amplitude modulator 2 may be four, and the number of the transducers 3 is four.

Please refer to Figures 3, 4, 5 and 6, the second embodiment of the present invention, the number of input parts 21 of the modulator 2 can be adjusted according to the implementation requirements, for example, eight, and the number of the transducers 3 is correspondingly eight.

Please refer to Figures 5 and 7. The eight transducers 3 provide high-frequency mechanical vibrations respectively. The mechanical vibrations are transmitted to the two amplitude modulators 2 via the input parts 21 connected to the transducers 3. The two amplitude modulators 2 then transmit the mechanical vibrations to the welding head 1 respectively. The welding surface 11 of the welding head 1 can be used to weld the workpiece. Because there are a total of eight transducers 3 to provide mechanical vibrations, the amplitude of the welding head 1 can be effectively enhanced, which is particularly suitable for large workpieces. Because the amplitude of the welding head 1 is larger, the welding operation of large workpieces can be completed at one time.

Please refer to Figures 8 and 9. In the third embodiment of the present invention, the appearance of the two amplitude modulators 2 is different from that of the first and second embodiments. The appearance of the two amplitude modulators 2 of the first and second embodiments is roughly forked, while the appearance of the two amplitude modulators 2 of the third embodiment is roughly block-shaped. The appearance of the two amplitude modulators 2 can be adjusted according to the implementation requirements.

Thus, the input parts 21 of the two amplitude modulators 2 can be respectively provided with the transducer 3, and the mechanical vibration provided by the transducer 3 is transmitted to the two amplitude modulators 2 via the input parts 21, and the two amplitude modulators 2 then respectively transmit the mechanical vibration to the welding head 1 in a concentrated manner, thereby enhancing the amplitude of the welding head 1 and achieving the purpose of improving welding efficiency.

The above discussion is only the best implementation example of this creation, and is not intended to limit the scope of implementation of this creation; therefore, any equivalent shape, structure or combination changes made within the spirit and scope of this creation should be included in the scope of the patent application for this creation.
