Embodiment 1

[0037] Please refer to FIG. 1 , this embodiment provides a method for manufacturing a hyperboloid lens, and the process flow is as follows:

[0038] Select the sheet and carry out UV transfer - electroplating on the UV transfer surface - printing on the electroplating surface - drying the printed sheet - stripping - attaching a protective film and punching - punching the sheet into individual pieces - thermoforming —Put the sheet into the mold for injection molding.

[0039] Specifically include the following steps:

[0040] S01. Select a sheet and perform UV transfer printing on the sheet; wherein, the material of the sheet is any one of PC and PET, and the thickness of the sheet is preferably 0.125-0.15 mm. Among them, light curing is carried out at a speed of 20-30m / min, and the energy is 800-1000mj / cm 2 Curing treatment of UV transfer sheet.

[0041] S02, carrying out one-side electroplating (UV transfer printing one side) to the sheet material of UV transfer printing; ...

Abstract

The invention relates to a method for manufacturing a mobile phone lens, in particular to a method for manufacturing the double-curved-surface lens. The method comprises the steps that a sheet is selected, UV transfer printing is carried out on the selected sheet, electroplating treatment is carried out on a transfer printing face, according to needs, different colors are electroplated, printing is carried out on an electroplating face, and the electroplating colors are set out; after printing, drying treatment is carried out, a protection film is laid up, a locating hole is punched, the whole sheet is punched singly, heat molding is carried out on the single sheet, and therefore the two side edges of the whole sheet are in a curved-surface state; and the molded sheet is put into a mold for injection molding. According to the method, the problems that after UV transfer printing, thermal deformation of a plane PC sheet is poor, and in the prior art, after the sheet is directly molded into the curved-surface lens via injection molding, UV transfer printing cannot be carried out, and poor printing is caused are effectively solved; and a double-curved-surface structure is attractive in appearance, and the double-curved-surface lens is a pioneer in a model machine.

Description

technical field [0001] The invention relates to the field of preparation of mobile phone lenses, in particular to a method for producing hyperboloid lenses. Background technique [0002] The existing production processes of mobile phone lenses include injection molding, strengthening, vacuum evaporation, screen printing, drying, electroplating, and CNC cutting. They are direct PMMA / PC sheet printing and cutting or making molds for injection molding, all of which are flat lenses with a monotonous style and no new ideas. The Chinese invention patent with application number 201410400495.7 discloses a preparation method of a flat-panel mobile phone lens. The method not only includes the formula of the mobile phone mirror surface, but also includes its preparation process. The lens is prepared by advanced technology. The lens has strong thermal stability, high imaging resolution, and an effective focal length of 5.5mm. However, the lenses it produces are still of the traditiona...
