Description

Technical Field

[0001] The utility model relates to the field of spraying, in particular to a spraying fixture. Background Art

[0002] At present, the spraying of earphone products mostly adopts the method of a fixed gun type automatic spraying line. Generally, the earphones to be sprayed are adhered to a jig plate with foam glue for spraying. During the production process, the rotation of the line body of the fixed gun type automatic spraying line may throw off the products, directly resulting in product scrapping; or the earphone products are directly inserted into a specific fixture for spraying, but this causes the part inserted into the fixture to be unable to be covered by spraying, and secondary spraying operations are still required.

[0003] Therefore, during the spraying process of existing earphone products, a buckle structure is designed in the spraying fixture, and the earphone products are fixed in the spraying fixture through the buckle structure. However, designing a buckle structure in the spraying fixture not only makes the structure design complex, the installation and removal of earphone products not easy to operate, but also easily damages the sprayed coating during the disassembly and assembly process, resulting in defective earphone products. This makes the spraying operation not only inefficient but also the yield rate of earphone products low.

[0004] Therefore, there is an urgent need for some new technologies or new jigs to solve the current problems. Summary of the Utility Model

[0030] Please refer to Figures 1-3, the present utility model discloses a spraying fixture for spraying the earphone housing 100, which includes a rotating bracket 10, a connecting member 20 installed on the rotating bracket 10, and a connecting bracket 30 connected to the connecting member 20. In this embodiment, the connecting bracket 30 is connected to the connecting member 20 by plugging and unplugging.

[0031] Please refer to Figure 4 , the rotating bracket 10 includes a vertically arranged support cylinder 11 and several support arms 12 extending horizontally outward along the outer wall of the support cylinder 11. A connecting seat 13 is provided at the end of each support arm 12.

[0032] Please refer to Figure 1 , Figure 6 and Figure 10 , the connecting member 20 has a first end 21 and a second end 23. The first end 21 of the connecting member 20 is installed on the connecting seat 13, and the connecting bracket 30 passes through the earphone housing 100 and is installed on the second end 23 of the connecting member 20. More specifically, in this embodiment, the earphone housing 100 is a hollow structure.

[0033] Please refer to Figure 4 and Figure 5 , the connecting seat 13 is recessed with a first groove 131, and the first end 21 of the connecting member 20 is installed in the first groove 131. Second grooves 132 communicating with the first groove 131 are recessed on both side walls of the first groove 131. Installation parts 22 are protruded on both side walls of the first end 21 of the connecting member 20 corresponding to the second grooves 132, and the installation parts 22 are correspondingly clamped in the second grooves 132. During installation, the first end 21 is fixed in the first groove 131 by inserting the installation parts 22 vertically into the second grooves 132, so as to realize the connection between the connecting member 20 and the connecting seat 13 of the rotating bracket 10.

[0034] Please refer to Figure 5 and Figure 6 , further, a limiting protrusion 133 is protruded on the side wall of the second groove 132, and a clamping part 221 is protruded on the end face of the installation part 22 corresponding to the limiting protrusion 133. When the connecting member 20 is installed on the connecting seat 13, the limiting protrusion 133 is located above the clamping part 221 to block the clamping part 221, so as to prevent the connecting member 20 from detaching from the connecting seat 13. This makes the connection between the connecting member 20 and the connecting seat 13 of the rotating bracket 10 more stable.

[0035] Please refer to Figure 7 and Figure 8, the connecting bracket 30 includes a connecting arm 32 and a shielding plate 31 fixedly connected to one end of the connecting arm 32. In this embodiment, the connecting arm 32 is generally in a "C" shape. The earphone housing 100 has a first opening 102 and a second opening 101. When the connecting arm 32 extends into the earphone housing 100, the shielding plate 31 covers the first opening 102 of the earphone housing 100 to prevent spraying material from entering the interior of the earphone housing 100 during the spraying process. And the other end of the connecting arm 32 is mounted on the second end 23 of the connecting member 20, and the second end 23 of the connecting member 20 covers the second opening 101 of the earphone housing 100 to prevent spraying material from entering the interior of the earphone housing 100 during the spraying process.

[0036] Please refer to Figure 6 and Figure 10 , further, the second end 23 of the connecting member 20 is provided with a socket hole 231, and the other end of the connecting arm 32 is inserted into the socket hole 231 to fix the connecting bracket 30 on the connecting member 20.

[0037] Please refer to Figure 6 , Figure 8 and Figure 9 , a positioning block 104 is provided at the end of the second opening 101 of the earphone housing 100, and a positioning groove 232 corresponding to the positioning block 104 is provided at the second end 23 of the connecting member 20, and the positioning block 104 is correspondingly installed in the positioning groove 232. By setting the positioning block 104 and the positioning groove 232 to match, not only can it provide a positioning direction for the earphone housing 100 when it is installed on the connecting member 20, but also it can make the connection between the earphone housing 100 and the connecting member 20 further achieve a more stable effect.

[0038] Please refer to Figures 1-4 , several support arms 12 are arranged at equal intervals around the support cylinder 11, and a connecting rib 14 is connected between the connecting seats 13 at the ends of adjacent support arms 12. By providing the connecting rib 14, the rotating bracket 10 can maintain stable rotation during rotation without the situation that the connecting seat 13 swings randomly. In this embodiment, the connecting rib 14 is arc-shaped, and a plurality of the connecting ribs 14 are annularly connected to the outer periphery of the support cylinder 11.

[0039] Furthermore, in this embodiment, the number of the connecting ribs 14 is five, and the number of the support arms 12 is five, so that the hollow space formed by two adjacent support arms 12 and the connecting rib 14 located between the two support arms 12 is larger. When ensuring the support strength of the support arms 12, it is more conducive to improving the yield of spraying and vacuum plating.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 8 . The spraying fixture further includes a rubber plug 40. The rubber plug 40 includes a pair of plugs 41 and a connecting wire connected to the pair of plugs. A pair of mounting holes 103 are provided on the outer surface of the earphone housing 100, and the pair of plugs 41 are mounted in the mounting holes 103 of the earphone housing 100. By mounting the plugs 41 in the mounting holes 103 of the earphone housing 100, it is possible to prevent the spraying material from entering the interior of the earphone housing 100 during spraying. By providing the connecting wire connected to the pair of plugs 41, it is not only convenient to remove and install the plugs, but also prevents the loss of the relatively small plugs 41.

[0041] The spraying fixture provided by the present utility model fixes the earphone housing 100 through the cooperation of the rotating bracket 10, the connecting member 20 and the connecting bracket 30. It not only has a simple structure, but also can quickly position the earphone housing 100 without a buckling structure, greatly improving the production efficiency.
