[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears.

[0003] In the current headphone production process, the exterior of the headphones needs to be sprayed with paint to enhance the product's appearance. However, most headphone painting equipment currently only sprays one headphone at a time. After the headphone is painted, the painting process is stopped before the headphone can be replaced and the painting process can continue. This results in more time being spent on painting, slowing down the work rate.

[0004] Therefore, a headphone spray coating production device is proposed. Summary of the Invention

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] Please refer to Figures 1 and 5. This utility model provides a headphone spraying production device, including a bottom box 1 with an opening at the top. Paint can be stored inside the bottom box 1 for spraying, resulting in better spraying effect. A liquid exchange port 17 is provided at the bottom of the bottom box 1, through which the internal paint can be replaced or discharged. A controller 117 and a level gauge 118 are installed on the outside of the bottom box 1. The controller 117 makes it easier for the operator to operate the electrical components in the device, making the operation more convenient. The level gauge 118 can monitor the internal paint level to avoid excessive or insufficient levels affecting the spraying. A removable filter layer 116 is provided at the upper end of the bottom box 1. The filter layer 116 allows the sprayed paint to fall downwards and be filtered and recycled, saving costs.

[0031] Please refer to Figures 1, 2, 3, and 4. A protective box 3 is installed in the middle of the bottom box 1 via a step to prevent paint from affecting the first motor 4. The first motor 4 is installed inside the protective box 3. A circular rotating plate 2 is connected to the upper output end of the first motor 4, located at the upper end of the bottom box 1. The upper surface of the rotating plate 2 can be tilted outwards, allowing excess paint to fall downwards during spraying. The first motor 4 drives the rotating plate 2 to rotate, causing the upper earpiece to slowly rotate, sequentially rotating into the spray frame 8 and drying frame 14, thus increasing automation efficiency. The outer side of the rotating plate 2 is connected to the bottom box 1 via a detachable stabilizing component, allowing for disassembly of components like the rotating plate 2 for subsequent maintenance. The stabilizing component includes a fixing rod 111 located on the outer side of the rotating plate 2. A rotating groove 112 is provided on the upper end of the inner wall of the bottom box 1. A rotating force-bearing block 113 is connected to the outer side of the fixing rod 111, rotatably connecting to the rotating groove 112. The stability of the rotating plate 2 is enhanced by the fixing rod 111, resulting in better stability during rotation. The rotating force block 113 and the rotating groove 112 are provided with roller grooves 114 on their corresponding surfaces. Several balls 115 are provided inside the roller grooves 114, which makes the rotating force block 113 roll better under the roller grooves 114 and the balls 115 during rotation, reducing jamming. Several support rods 7 are installed around the top surface of the rotating plate 2, which can hold multiple earphones, so that continuous spraying and other work can be carried out without interruption. The top of the support rod 7 is equipped with a detachable ejector pin 110, which makes it easy to install the earphones on it. The top of the support rod 7 is provided with a connecting screw hole 18. The bottom mounting plate of the ejector pin 110 is provided with a connecting screw 19 that connects to the connecting screw hole 18. The connection method of the connecting screw 19 and the connecting screw hole 18 makes it easy to disassemble and replace different ejector pins 110 for different earphones, making it more practical, easier to operate, and increasing the stability of earphone placement.

[0032] Please refer to Figure 1. Several fixed boxes 5 are installed on the outer side of the rotating plate 2 at the lower end of the support rod 7, and a second motor 6 is installed inside the fixed box 5. The output end of the second motor 6 is connected to the support rod 7. The second motor 6 drives the upper pin 110 to rotate under the force, thereby rotating the earphone placed on the pin 110. When the earphone rotates, the spraying effect is better, the spraying is more complete, and the effect is better. Moreover, when it rotates inside the drying frame 14, it can make the drying surface more evenly heated and accelerate the drying rate.

[0033] Please refer to Figure 1. A paint spray frame 8 with openings at the front and rear ends and the bottom is installed on the upper side of one side of the bottom box 1. A spray pipe 9 is laid inside the paint spray frame 8, and several nozzles 10 are provided inside the spray pipe 9. A pump body 12 is installed on the outside of the bottom box 1 through a pump box 11. The liquid outlet of the pump body 12 is connected to the spray pipe 9 through a liquid delivery pipe 13, and the suction end of the pump body 12 penetrates through the bottom of the bottom box 1. The operation of the pump body 12 allows the paint liquid inside the bottom box 1 to be drawn out and fed into the spray pipe 9 through the liquid delivery pipe 13, and then sprayed outward under the action of the nozzles 10, thereby spraying the headphones. A drying frame 14 with openings at the front and rear ends and the bottom is connected to the upper side of the other side of the bottom box 1. A heating chamber 15 is provided inside the drying frame 14, and a heating element 16 is installed inside the heating chamber 15. When the heating element 16 generates heat, the headphones that have been sprayed into the drying frame 14 can be dried, thereby avoiding the low efficiency of natural air drying and speeding up the work.

[0034] Working principle: In use, first connect the first motor 4, the second motor 6, the pump body 12, the heating element 16, and the controller 117, and connect them to an external power supply. Then, place the earpiece on the top of the ejector pin 110. Driven by the first motor 4, the rotating plate 2 rotates slowly. During rotation, the earpiece can be placed on different ejector pins 110 at the same time. After rotation, the earpiece is rotated to the bottom of the spray frame 8. The pump body 12 draws out the paint from the bottom box 1 and inputs it into the spray pipe 9 through the infusion tube 13. The paint is then sprayed onto the earpiece through the nozzle 10. The second motor 6 drives the support rod 7 to rotate, causing the earpiece to rotate and spray. During spraying, the rotating plate 2 rotates, causing the other earpiece to rotate and be sprayed inside the spray frame 8. After spraying, the earpiece rotates into the drying frame 14 and is dried by the heating element 16 inside the heating chamber 15. After drying, the earpiece is removed and the spraying process is repeated to complete the work.
