Description

Technical Field

[0001] The utility model belongs to the technical field of optical lenses, and in particular relates to a high-definition optical lens processing jig. Background Art

[0002] Optical glass lenses are the material used to make glasses;

[0003] Optical lenses are made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasound to remove bubbles; then slowly cooled for a long time to prevent the glass block from generating internal stress. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to form optical lens blanks. The optical lens blanks need to be fixed by processing jigs, and the optical lens blanks are sent to the grinding device to grind the surface of the optical lens blanks.

[0004] Since both sides of the optical lens blank are arc-shaped, with one side bulging outward and the other side bulging inward, the processing jig can only fix one side of the optical lens blank. When grinding the outer wall of the other side of the optical lens blank, it is necessary to replace the processing jig to fix the optical lens blank, resulting in the need to frequently replace the processing jig during the grinding process, which wastes a lot of time in replacing the processing jig when grinding the optical lens blank.
