Technology for reducing scratches of glass optical lenses during engraving

Abstract

The invention relates to a technology for reducing scratches of a glass optical lens during engraving, and concretely relates to a production technology of the glass screen of a large-screen intelligent mobile phone and a panel computer before an engraving process. The technology comprises the following steps: cutting large piece glass, cleaning, examining, carrying out double side film coverage by adopting a film covering machine, cutting off the superfluous film at the edge of glass after the glass film coverage, engraving the glass, uncovering the film after glass engraving, and subsequently processing. The film coverage treatment process of the right side and the wrong side of the glass lens is carried out before the engraving process, so the technology reduces the contact of the surface of the glass with the outside in the engraving process, thereby the scratching probability is reduced, and the yield is improved; and no polishing treatment is carried out after the glass product is engraved, so the polishing process is omitted, and the production cost is reduced.

Description

technical field [0001] The invention relates to a process for reducing scratches of glass lenses during engraving, which is a production process for glass screens of large-screen smart phones and tablet computers before the engraving process. Background technique [0002] At present, digital products are becoming more and more popular, and the demand for tablet computers and large-screen smartphones is steadily increasing. Due to the high transmittance and hard texture of glass materials, it is widely used in tablet computers and large-screen smartphones, etc. Screen manufacturing of digital products. The traditional glass lens production process is: glass cutting, cleaning, engraving, polishing, and cleaning before strengthening. After engraving, the lens needs to be transferred to the polishing process to remove scratches on the glass surface, but the main component of the polishing powder used in the polishing process is rare earth. Now that the state has introduced a p...

The traditional glass lens production process is: glass cutting, cleaning, engraving, polishing, and cleaning before strengthening. After engraving, the lens needs to be transferred to the polishing process to remove scratches on the glass surface, but the main component of the polishing powder used in the polishing process is rare earth

Now that the country has introduced a policy to restrict the export of rare earths, the domestic price of rare earths has also doubled to three times, resulting in a substantial increase in production costs
