Method for manufacturing coated convex reflectors for mobile telephone auto heterodyne

Abstract

The invention discloses a method for manufacturing coated convex reflectors for mobile telephone auto heterodyne. The method comprises the following steps of: 1) heating an optical transparent plastic sheet to 80 to 100 DEG C, and performing hot-forming by using a mould to obtain a plurality of convex reflector matrixes with crescent sections; 2 spraying hardening liquid on the surface of the sheet which is subjected to hot-pressing, and curing; 3) coating aluminum films on the concave sides of the convex reflector matrixes of the sheet on which the hardening liquid is sprayed, and coating protective coatings on the aluminum films; 4) printing ink on the aluminum films of the convex reflector matrixes by a screen-printing method to shield the aluminum films on the convex reflector matrixes; 5) drying sheet on which ink is printed, wherein a plurality of coated convex reflectors are formed on the dried sheet; and 6) dividing the plurality of coated convex reflectors on the sheet into discrete components, wherein after being subjected to die cutting and gum application, the discrete components can be used for the assembly of a mobile phone. In the method, the aluminum films are coated on the concave sides of the reflectors to effectively prevent the reflectors from being worn and prolong the service life of the reflectors.

Description

technical field [0001] The invention relates to a method for manufacturing a reflector, in particular to a method for manufacturing a coated convex reflector for a mobile phone selfie. Background technique [0002] At present, the self-portrait mirror for mobile phones uses an injection molded part with a crescent-shaped cross section as the substrate. First, a layer of plastic UV hardening solution is sprayed on the surface of the substrate. After the UV hardening solution is dried, an aluminum film is coated on the convex surface of the substrate. Finally, spray a layer of plastic UV hardening liquid on the surface of the aluminum film. During the use of mobile phones, the outer plastic UV hardened layer is easy to wear and tear. After the plastic UV hardened layer is worn, the aluminized film is exposed, which eventually leads to the wear of the unprotected aluminized film. The wear of the aluminized film directly leads to the damage of the reflector. The emissivity drop...

Problems solved by technology

During the use of mobile phones, the outer plastic UV hardened layer is easy to wear and tear. After the plastic UV hardened layer is worn, the aluminized film is exposed, which eventually leads to the wear of the unprotected aluminized film. The wear of the aluminized film directly leads to the damage of the reflector. The emissivity rate drops, which affects shooting, thus shortening the service life of the mobile phone selfie mirror

Moreover, the above-mentioned reflective mirror for mobile phone selfies and the protective screen in front of the camera of the mobile phone are discrete components manufactured separately, and processing, packaging, and installation all need to be carried out independently, resulting in many processes and low efficiency.
