Abstract

The invention relates to a high-precision optical lens manufacturing and machining method, in particular to an automatic chamfering device for high-precision optical lens manufacturing and machining.The automatic chamfering device comprises a machine table, an automatic conveying mechanism used for vertically conveying round lenses, a pushing mechanism used for horizontally pushing the round lenses, a discharging supporting plate mechanism, a front blocking positioning assembly, a chamfering mechanism and a pressing mechanism. According to the device related to the method provided by the invention, a series of continuous automatic machining operations of automatic upward conveying, automatic horizontal pushing, automatic chamfering positioning, automatic chamfering machining and automaticdischarging of the lenses can be completed through mutual cooperation of the arranged mechanisms, a traditional manual machining mode is replaced, the labor cost is reduced, the machining efficiencyis greatly improved, the machining precision is controllable and unified, and the overall machining quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of optical lens manufacturing and processing, and specifically proposes a high-precision optical lens manufacturing and processing method. Background technique [0002] Optical glass is mixed with oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasonic waves, and removed air bubbles; Slowly cool down over time to avoid internal stress in the glass block. The cooled glass block is then measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications; the qualified glass block will be processed by heating and forging into optical lens blanks. [0003] The raw materials of optical lens blanks will be further processed through milling, fine grinding, polishing, edging, co...
