Abstract

The invention discloses a special optical lens for a mobile phone, and relates to the technical field of optical lenses. An optical lens special for a mobile phone comprises a lens body, the lens bodyis of a cylindrical structure, a top arc part is integrally formed at the top of the lens body, side arc parts are integrally formed on the periphery of the lens body, and the lens body, the top arcpart and the side arc parts are all made of glass. The processing method comprises the following steps: S1, cutting an optical lens blank material A from a glass raw material by using a glass engraving machine according to the size of the optical lens; s2, grinding a top arc part and a side arc part to obtain a semi-finished product B by using an edge grinding machine according to the designed shape of the optical lens; according to the invention, through the arrangement of the strengthening furnace strengthening process, the pressure stress layer is formed on the surface of the optical lens after the optical lens is subjected to the heat treatment process, the optical lens has a special fragment state, and when the optical lens is subjected to external force, the pressure stress layer cancounteract part of tensile stress.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a special optical lens for mobile phones and a processing method thereof. Background technique [0002] Optical lens refers to a lens with high light transmittance formed by optical glass through multiple processing procedures. Optical glass is made of oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. Mix according to a specific formula, melt in a platinum crucible at high temperature, stir evenly with ultrasonic waves, and remove air bubbles; then cool down slowly over a long period of time to avoid internal stress in the glass block. After cooling, the glass block must be measured by optical instruments to test its purity, Whether the transparency, uniformity, refractive index and dispersion rate meet the specifications, the qualified glass block is heated and forged to form an optical lens blank. [0003] Most of the ...
