Embodiment Construction

[0024] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The invention provides a processing method of a shading ring, referring to figure 1 , in one embodiment, the processing method of the shading ring includes the following steps:

[0026] Step S10, providing a shading ring, the shading ring includes a main body, an antistatic coating coated on the main body, and a through hole formed on the main body, the main body is made of plastic material, and the antistatic The coating is a layer of carbon powder, and the through holes are formed by punching.

[0027] Specifically, in this embodiment, the thickness of the shading ring is 0.025 mm, the diameter of the through hole is 2.14 mm, and the body is made of polyethylene terephthalate.

[0028] Because the manufacturing method of the light-shielding ring is to form the main body first, then apply an antistatic coati...

Abstract

The invention discloses a shading ring processing method and a shading ring. The method comprises the following steps that the shading ring is provided, the shading ring comprises a body, an anti-static coating and a through hole, the anti-static coating coats the body, the through hole is formed in the body, the body is made of plastic materials, and the anti-static coating is a carbon dust layer; the wall of the through hole is corroded through aqueous alkali to form a matte structure. According to the shading ring processing method and the shading ring, the shading ring is processed inside an ultrasonic generator through aqueous alkali so that the matte structure can be formed on the wall of the through hole of the shading ring, the poor phenomena of dazzling, halo, ghosting and the like caused by reflection of the wall of the through hole are avoided, and therefore the photographing effect is ensured and the photographing product quality is improved.

Description

technical field [0001] The invention relates to the technical field of imaging, in particular to a processing method of a light shielding ring and the light shielding ring. Background technique [0002] Generally, 3 to 5 shading circles need to be placed inside the cameras of high-resolution mobile phones and digital cameras to adjust the light aperture and block other stray light. In the past, metal stamping was used to oxidize and blacken to achieve full extinction. However, the cost and the plastic shading ring are several times more expensive. In recent years, with the sharp drop in cost, polyethylene terephthalate (PET) raw materials with anti-static high shading coating on the surface have been directly punched instead , but as the pixels get higher and higher, the cross-section of the inner hole after plastic stamping will leave a shiny cut surface, but it cannot be treated with traditional blackening and matting like metal, so that obvious glare, halo and Defects su...
