CN103481144A - Processing technic for ultrathin glass lens of mobile phone camera - Google Patents

Abstract

The invention relates to a processing technic for a lens of an ultrathin mobile phone camera. The processing technic comprises the steps that a glass cutting machine is firstly used for carrying out sub cutting on a glass raw material according to the size 5-10 times the size of the outer contour of the ultrathin glass lens of the camera, then rough grinding is carried out for thinning, polishing is carried out for thinning, secondary sub cutting is carried out, and bunching profile modeling is carried out; then cleaning is carried out, chemical tempering is carried out, finally, silk-screen printing of a non-polished surface is carried out, and evaporation plating is carried out for forming an antireflection film and an anti-fingerprint film. The processing technic has the beneficial effects that the ultrathin camera lens can be applied to a mobile phone, and the mobile phone can be made more delicate, more attractive and thinner.

Description

A kind of processing technology of mobile phone cam ultra-thin glass eyeglass

Technical field

The present invention relates to a kind of processing technology of ultra-thin glass, particularly a kind of processing technology of mobile phone cam ultra-thin glass eyeglass.

Background technology

Increasingly popular and universal along with smart mobile phone; Requirement to its thickness is also carried out towards more and more thinner direction; And crucial for it building block--it is more and more thinner that the camera glass lens certainly will also will be done, thickness of glass reaches 0.3 ± 0.03mm, and therefore, our manufacture craft is arisen at the historic moment.

Summary of the invention

The object of the invention is to produce the mobile phone cam ultra-thin glass eyeglass that thickness is 0.3mm, specifically technical scheme is, a kind of processing technology of mobile phone cam ultra-thin glass eyeglass, and this technique comprises following step,

(1), once divide cutting: the cuttings in 5 ~ 10 times of minutes by the outer profile size of camera ultra-thin glass eyeglass by raw material with glass cutting machine;

(2), corase grind attenuate: use and take kibbling mill and as carrier coordinates the diamond abrasive pad, the sheet glass after cutting apart is roughly ground and is thinned to 0.4mm;

(3), polishing attenuate: to being thinned to the 0.4mm sheet glass, use polishing machine to carry out polishing and be thinned to 0.3 ± 0.03mm;

(4), secondary divides cutting: the sheet glass with glass cutting machine after to attenuate carries out secondary by the outer profile size of camera ultra-thin glass eyeglass and divides cutting;

(5), bunching profiling: outline bunching profiling frosted is carried out in the glass lens stack that several pieces secondaries are cut;

(6), cleaning and chemical tempering: the complete product of profiling is cleaned and chemical tempering;

(7), serigraphy: the glass white sheet after tempering carries out the thoroughly black serigraphy of frame;

(8), plated film: the glass lens finished printing carries out vacuum coating (AR) and the anti-fingerprint film (AF) of vacuum evaporation.

The beneficial effect that the present invention produces is batch production and the application that has realized the ultra-thin glass camera; The march toward paces in ultra-thin stage of smart mobile phone have actively been coordinated; Meet the consumer and pursued the spiritual demand of personalized and sophistication at society.

The specific embodiment

Take a kind of mobile phone cam ultra-thin glass eyeglass 8*8*0.3 ± 0.03 mm is example, the glass plate of glass raw material 470*370*0.55mm that first will be relatively thick divides the pieces of glass that is cut into 80*80*0.55mm; The kibbling mill of take again is thinned to 0.4mm as carrier coordinates the diamond abrasive pad to roughly grind; Then use polishing machine to carry out polishing and be thinned to 0.3 ± 0.03mm; Then carry out secondary and divide cutting, use profiling machine to undercut appearance profile size 8*8mm; Cleaned again and chemical tempering; Finally carry out thoroughly black serigraphy and anti-reflection the reaching of vacuum evaporation of non-burnishing surface frame and prevent fingerprint film, border width is 1.8 ± 0.05mm.
