Description

Technical Field

[0001] The utility model relates to the technical field of ultrasound, and in particular to an ultrasonic welding structure capable of reducing the shaking of a welding head. Background Art

[0002] Ultrasonic welding utilizes a generator to generate a high-voltage, high-frequency signal. This signal is converted into high-frequency mechanical vibrations through a transducer system. This vibration is then applied to the plastic workpiece. Friction between the workpiece surface and internal molecules causes the temperature of the weld to rise. When the temperature reaches the melting point of the workpiece itself, the workpiece interface rapidly melts, filling the gap between the interfaces. When the vibration stops, the workpiece cools and sets under a certain pressure, completing the weld.

[0003] In the prior art, a vibrator is connected to a welding head, which drives the welding head to vibrate at a high frequency so that the welding head can ultrasonically weld an object. However, during installation, the mounting structure is often mounted on the vibrator. In this way, the installation position is too far away from the welding surface of the welding head, resulting in excessive shaking of the welding head. Utility Model Content

[0004] The purpose of the present invention is to provide an ultrasonic welding structure that reduces the shaking of the welding head, aiming to solve the problem in the prior art that the installation position of the vibrator is too far away from the welding surface of the welding head, resulting in excessive shaking of the welding head.

[0006] Furthermore, the welding head is arranged longitudinally, and the mounting structure and the welding bottom surface are arranged longitudinally.

[0007] Furthermore, a plurality of mounting structures are provided on the mounting surface, and the plurality of mounting structures are arranged at intervals along the length direction of the mounting surface.

[0008] Furthermore, the mounting structure includes a connecting section connected to the mounting surface, the connecting section has a longitudinal section extending upward, and the top of the longitudinal section has a transverse section extending outward away from the mounting surface.

[0009] Furthermore, the longitudinal section and the mounting surface are spaced apart to form a mounting gap, and the longitudinal section and the transverse section are arranged perpendicularly.

[0010] Furthermore, the welding head is arranged in a flat shape.

[0011] Furthermore, the thickness of the upper portion of the welding head is greater than the thickness of the lower portion of the welding head, and the mounting structure is located on the upper portion of the welding head.

[0012] Furthermore, the thickness of the lower portion of the welding head gradually decreases from top to bottom.
