Description

Technical Field

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

[0002] As people's quality of life improves, more and more electronic products, such as headphones, are entering our lives. To achieve a smooth and bright appearance, headphone shells are often sprayed with materials such as protective paint, color paint, or varnish. This requires assembling the headphone shells on a fixture for the spraying process.

[0003] The existing spraying fixture of the earphone housing 100' (see Figure 9 ) includes a rotating bracket 10' installed on the equipment, and several mounting seats 11' are vertically arranged on the outer periphery of the rotating bracket 10'. When in use, the earphone shell 100' is placed on the mounting seat 11' for spraying. However, in the existing spraying fixture, when the earphone shell 11' is installed on the mounting seat, one end of the support tube 12' close to the rotating bracket 10' is too low, so that the coloring area cannot be completely exposed to the range of the spray gun, so the coloring consistency requirement cannot be met, resulting in a defective earphone shell 100'. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a spraying fixture with a directional assembly structure that can ensure that the earphone shell is completely exposed within the range of the spray gun and greatly improve the spraying yield.

[0028] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of elements other than the listed elements and may also include additional elements not specifically listed.

[0029] See also Figures 1-8 The utility model discloses a spraying fixture with a directional assembly structure for spraying an earphone housing 100, including a rotating bracket 10 and a directional assembly structure 20 installed on the rotating bracket 10 for supporting the earphone housing 100. The rotating bracket 10 includes a vertically arranged support tube 11 and several support arms 12 arranged at intervals and extending outward along the outer wall of the support tube 11. A mounting seat 13 is provided at the end of each support arm 12. The upper surface of the mounting seat 13 is provided with a mounting groove 131 for installing the directional assembly structure 20. The groove bottom surface 132 of the mounting groove 131 is set at an angle with the horizontal plane, and the angle is 30~60°. The directional assembly structure 20 includes a seat body 21. The lower end of the seat body 21 is provided with an abutting surface 212 that abuts against the groove bottom surface 132 of the mounting groove 131. The upper end of the seat body 21 is provided with a supporting surface 211 that supports the supporting surface 102 of the earphone housing 100. The supporting surface 211 is arranged parallel to the abutting surface 212. The middle part of the supporting surface 102 is provided with a model structure 23 that matches the cavity 101 of the earphone housing 100. In this embodiment, when the angle between the bottom surface 132 of the groove and the horizontal plane is less than 30°, the end of the earphone housing 100 close to the support tube 11 will be too low and affect the coloring. When the angle between the bottom surface 132 of the groove and the horizontal plane is greater than 60°, the end of the earphone housing 100 away from the support tube 11 will be too low and affect the coloring. Therefore, in this embodiment, the optimal angle is 45°, and at the angle setting value of 45°, the yield of the earphone housing 100 can reach more than 99.8%.

[0030] See also Figure 3-Figure 6, vertically extending fixing columns 133 are provided on both sides of the mounting seat 13 for fixing the directional assembly structure 20, and positioning blocks 22 are convexly provided at both ends of the seat body 21 of the directional assembly structure 20 corresponding to the fixing columns 133, and the two fixing columns 133 are recessed on the opposite side with positioning grooves 134 for accommodating the positioning blocks 22, and the positioning grooves 134 are provided with openings 135 toward the side walls of the support tube 11, and the positioning blocks 22 enter the positioning grooves 134 from the openings 135.
