DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] See also Figure 1-5 The embodiment of the utility model provides a technical solution: the earphone shell painting device includes a base 1, a turntable 2 is rotatably connected to the top of the base 1, a plurality of connecting blocks 3 are arranged in a circular array on the peripheral side of the turntable 2, a gear ring 4 is fixedly connected to the base 1, and one end of each connecting block 3 away from the turntable 2 is vertically rotatably connected to a first bevel gear 5, each first bevel gear 5 is meshed with the gear ring 4, and each connecting block 3 is horizontally rotatably connected to a second bevel gear 6, each second bevel gear 6 is meshed with each first bevel gear 5 one by one, and each second bevel gear 6 is A thimble 7 is fixedly connected to the top, a fixing seat 10 is fixedly connected to the base 1, a clamp body is detachably connected to the fixing seat 10, a spray gun 15 is sleeved in the clamp body, and a driving member for driving the turntable 2 to rotate is provided at the bottom of the base 1. Specifically, the output end of the motor 18 is coaxially fixedly connected to the turntable 2, and a support rod 9 is horizontally provided at one end of each connecting block 3 away from the turntable 2. The first bevel gear 5 is rotatably sleeved on the support rod 9, and a limiting hole 8 is provided on the top of each connecting block 3, and the thimble 7 penetrates and is rotatably connected in the limiting hole 8.

[0021] As a preferred technical solution, the cross-section of the gear ring 4 is trapezoidal, and the teeth on the side surfaces of the gear ring 4 are all inclined. Specifically, the inclined setting is to facilitate the engagement of the gear ring 4 with each first bevel gear 5. When each connecting block 3 rotates around the output shaft of the motor 18, each first bevel gear 5 rotates while driving the second bevel gear 6 and the ejector pin 7 to rotate synchronously. When the earphone shell orbits to the painting range of the spray gun 15, the earphone shell rotates at the same time, so that the earphone shell can be painted without dead angles, realizing assembly line painting operations, and greatly improving the painting efficiency. Preferably, an annular groove is provided on the top surface of the gear ring 4, and an arc-shaped slider is provided at the bottom of each connecting block 3. Each arc-shaped slider is slidably connected in the annular groove, so that the rotation of each connecting block 3 is more stable.

[0022] As a preferred technical solution, the clamp body includes two half hoops 12, the inner walls of the two half hoops 12 are abutted against the spray gun 15, and the two ends of the two half hoops 12 are respectively fixedly connected with a first connecting plate 13 and a second connecting plate 16, the two first connecting plates 13 are screwed together, and the two second connecting plates 16 are coaxially screwed on the fixed seat 10. Specifically, the inner walls of the half hoops 12 are tightly fitted with the side surfaces of the barrel of the spray gun 15, which increases the friction between the clamp body and the spray gun 15, and prevents the spray gun 15 from slipping off the clamp body and affecting the painting effect.

[0023] As a preferred technical solution, two grooves 11 are symmetrically provided on the fixing seat 10, and two second connecting plates 16 are slidably connected to the two grooves 11 in a one-to-one correspondence. Specifically, a fixing plate 17 is provided between the two grooves 11, and the fixing plate 17 is integrally formed with the fixing seat 10. A threaded hole is provided on the fixing plate 17, and the bolts 14 fix the two second connecting plates 16 to both sides of the fixing plate 17 through the threaded hole. The positions of the two second connecting plates 16 in the two grooves 11 can be adjusted according to the diameter of the barrel of the spray gun 15, and the size of the through hole formed by the two half hoops 12 can be adjusted to adapt to spray guns 15 with different barrel diameters.

[0024] Working principle: The headphone shell painting device connects the spray gun 15 to the compressor, adds paint to the pot of the spray gun 15, plugs the headphone shell into each ejector pin 7, and drives the turntable 2, the connecting block 3 and the ejector pin 7 to rotate around its output shaft through the motor 18, so that each headphone shell revolves around the output shaft of the motor 18. Through the engagement between the ring gear 4, the first bevel gear 5 and the second bevel gear 6, when the headphone shell revolves to the painting range of the spray gun 15, the headphone shell rotates at the same time, so that the headphone shell can be painted without dead angles, realizing assembly line painting operation, and greatly improving the painting efficiency.

[0025] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
