Embodiment 1

[0039] Ultrasonic welding transducer 7 universal adjustment device, combined with the attached figure 1 , attached figure 2 And attached image 3 As shown, it is mainly composed of an adjusting block mounting plate 2, an adjusting fixed cover 3, an adjusting fixed seat 4, a fixed ring, an adjusting pressing piece 8, and an adjusting mechanism. The adjusting block mounting plate 2 is fixedly connected with the output end of the cylinder, the adjusting fixed cover 3 is ring-shaped, and the adjusting fixed cover 3 and the adjusting block installing plate 2 are connected by bolts; the adjusting fixed cover 3 is provided with a central hole, and the axis of the central hole It coincides with the centerline of the adjusting and fixing cover 3 , and the part of the adjusting and fixing cover 3 near the central hole is formed with a first arc-shaped surface 31 .

[0040]The adjustment fixing seat 4 and the adjustment fixing cover 3 are fixed by bolts, and an installation space is f...

Embodiment 2

[0046] The difference between this embodiment and embodiment 1 is that: Figure 4 And attached Figure 5 As shown, the adjusting mechanism in the present embodiment is mainly composed of several jacks 14 and several second adjusting rods 11, and several jacks 14 are evenly distributed with the center of the adjusting holder 4 as the center of circle, and each jack 14 A plurality of limiting protruding rings 15 are welded or integrally formed along the axial direction of the socket 14 , and the limiting protruding rings 15 are equidistantly arranged, and a limiting groove 16 is formed between adjacent limiting protruding rings 15 . Each limiting protruding ring 15 is provided with a notch, and all the notches are distributed along the axial direction of the insertion hole 14 and are located on the same straight line, and all the notches form a slideway 17 . Several indicating points 18 for indicating the position of the slideway 17 are welded on the adjustment fixing seat 4, a...

Embodiment 3

[0055] The difference between this embodiment and Embodiment 1-2 is that: this embodiment also includes several pressing units for enhancing the stability of the first adjusting rod 9 / second adjusting rod 11, combined with the attached Figure 6 And attached Figure 7 As shown, the pressing unit is arranged on the adjustment fixing seat 4, and the pressing unit is mainly composed of a limiting piece 20, a rotating piece 21, and a spring ring 19. The limiting piece 20 is welded on the first adjusting rod 9 / second adjusting rod 11 On the side away from the adjustment pressing piece 8, the rotating piece 21 can rotate or move on the limit piece 20, and the rotating piece 21 is provided with a rotating hole, so that the first adjusting rod 9 / second adjusting rod 11 can be placed in the rotating hole. Inner rotation; and the limit piece 20 cannot pass through the rotation hole. One end of the spring ring 19 is welded on the rotating piece 21 , the other end of the spring ring 19 i...

Abstract

The invention relates to the technical field of headphone welding and discloses an ultrasonic welding transducer universal adjustment device. The device comprises an adjustment block mounting plate connected to a cylinder, wherein an adjustment fixed cover is arranged on the adjustment block mounting plate, a central hole is formed in the adjustment fixed cover, and a first arc-shaped surface is arranged on a part, close to the central hole, of the adjustment fixed cover; an adjustment fixed seat is arranged on the adjustment fixed cover, a mounting space is formed between the adjustment fixedseat and the adjustment fixed cover, a fixed ring used for mounting a transducer is arranged in the mounting space, a second arc-shaped surface is arranged on the side, facing the central hole, of the fixed ring, and the second arc-shaped surface is matched with the first arc-shaped surface and can perform universal rotation on the first arc-shaped surface; an adjustment pressing sheet is arranged on the side, away from the second arc-shaped surface, of the fixed ring; and an adjustment mechanism used for ejecting the adjustment pressing sheet is arranged on the adjustment fixed seat. According to the scheme, universal adjustment of the transducer in the output end direction can be realized, and the demand for headphone welding at different angles is met.

Description

technical field [0001] The invention belongs to the field of earphone welding. Background technique [0002] The earphones we use in our daily life have some earphone holes on them. In the production of earphones, it is necessary to use an ultrasonic welding machine to weld the dust-proof net to the earphone holes. Ultrasonic welding machine is a special welding equipment using ultrasonic technology. When welding, ultrasonic welding machine does not add any adhesives, fillers or solvents, and does not consume a lot of heat. It has the advantages of simple operation and high welding strength. [0003] The welding head of the ultrasonic welding machine is generally connected to the output end of the transducer, and the transducer is generally installed on the connection part of the cylinder. When welding the earphone dust-proof net, different earphones may have different welding angles, but the existing transducer can only move in a single direction, cannot realize universal ...
