preparation example Construction

[0033] see figure 1 , the invention provides a method for preparing a rolled copper shading ring sheet, which comprises the steps of:

[0034] S1: Provide a formed shading ring, which is made of rolled copper.

[0035] Rolled copper is made by rolling copper ingots, then forging, anti-oxidation, roughening and other processes. The thickness of rolled copper is generally 5um ~ 135um. The molecules are tightly connected, with good flexibility, high strength, and bendability. , ductility, electroplating, good electrical conductivity, and excellent surface gloss; moreover, the rolled copper foil has low surface oxygen characteristics, and can be attached to various substrates, such as metals, insulating materials, etc., and has a wide range of temperature applications . The shading ring made of calendered copper material can avoid the shortcomings of PET material shading ring in the related art that are not resistant to aging, easy to deform, and not resistant to high temperatur...

Embodiment 1

[0059] The invention provides a method for preparing a rolled copper shading ring, which comprises the following steps:

[0060] (1) Provide a molded light-shielding ring piece made of rolled copper material.

[0061] (2) After washing with water, the light-shielding ring is ultrasonically cleaned for 10 minutes with acetone and 20 minutes with ethanol, so as to remove the rolling oil film attached to the surface of the light-shielding ring.

[0062] (3) After washing with water, the degreased light-shielding ring is polished with a copper polishing solution to remove the concave-convex structure on the surface of the light-shielding ring, and the polishing time is 5 minutes.

[0063] (4) After washing with water, place the polished light-shielding ring in the electroplating solution for electroplating, so as to attach a layer of copper bump layer on the surface of the light-shielding ring to increase the roughness of the light-shielding ring surface, The temperature of the e...

Embodiment 2

[0069] The invention provides a method for preparing a rolled copper shading ring, which comprises the following steps:

[0070] (1) Provide a molded light-shielding ring piece made of rolled copper material.

[0071] (2) After washing with water, ultrasonically clean the light-shielding ring for 20 minutes with acetone and 50 minutes with ethanol to remove the rolling oil film attached to the surface of the light-shielding ring.

[0072] (3) After washing with water, the degreased light-shielding ring is polished with a copper polishing solution to remove the concave-convex structure on the surface of the light-shielding ring, and the polishing time is 1 minute.

[0073] (4) After washing with water, place the polished light-shielding ring in the electroplating solution for electroplating, so as to attach a layer of copper bump layer on the surface of the light-shielding ring to increase the roughness of the light-shielding ring surface, The temperature of the electroplating...

Abstract

The invention provides a preparation method of a rolled and annealed copper darkening ring. The method comprises the following steps of providing a formed darkening ring made of rolled and annealed copper materials; degreasing the darkening ring; polishing the darkening ring; electroplating the darkening ring so that the surface of the darkening ring is plated with a copper nodule layer for improving the surface roughness of the darkening ring; activating the darkening ring; blackening the darkening ring for changing the surface color of the darkening ring; and drying the darkening ring to obtain the finished product of the rolled and annealed copper darkening ring. The invention further provides the rolled and annealed copper darkening ring. The preparation method of the rolled and annealed copper darkening ring is simple in steps and high in feasibility of implementation, and the rolled and annealed copper darkening ring produced is stable in dumb black structure, and is not liable to fall off; and the preparation method of the rolled and annealed copper darkening ring and the rolled and annealed copper darkening ring have the characteristics of easy blackening, simple technologyand low reflectivity after blackening.

Description

【Technical field】 [0001] The invention relates to the field of imaging technology, in particular to a method for preparing a rolled copper shading ring and a rolled copper shading ring. 【Background technique】 [0002] With the rapid development of science and technology, digital cameras and mobile phones with digital cameras are popularized rapidly, and the optical parts used in these optical instruments are gradually improved. The shading ring is an optical element used to regulate the luminous flux in the optical system. When the external light enters the lens, the unnecessary light can be blocked through the shading ring set between the lenses to prevent flare or ghosting in the camera image. . [0003] In the related art, the light-shielding ring is made of Japanese SOMA light-shielding material, which is double matte black polyethylene terephthalate (PET), and the light-shielding ring made of this material is not easy to exist. Conductive, not resistant to high temper...
