Abstract

The invention belongs to the technical field of the production of optical lenses and provides a tool and process for processing a white optical lens concave surface with diopter. The tool is provided with a disc-shaped main body; the circumference of the bottom surface of the disc-shaped main body is provided with flanged edges; raised sphere-crown shaped hollow cavities are formed in the flangededges; the middle part of the upper surface of the disc-shaped main body is provided with a central hole which is communicated with the sphere-crown shaped hollow cavities; two sides of the central hole are at least provided with an air inlet respectively, and the air inlets are communicated with the sphere-crown shaped hollow cavities; a circle of double-sided adhesive tape with matchable width is adhered to the bottom surface of each flanged edge; the sphere-crown shaped hollow cavities are internally provided with suction discs which match with the sphere-crown shaped hollow cavities in shape; the middle parts of the suction discs are provided with air inlet and outlet pipes which penetrate out from the central hole; and the air inlet and outlet pipes are internally provided with one-way valves which can ensure that air circulates from the inside of the suction discs to the outside under the action of negative pressure. In the invention, the double-sided adhesive tapes are adopted to obtain anti-sliding power, the suction discs are adopted to obtain anti-peel force, the white optical lens can be fixed firmly without falling off when being processed and can be peeled easily after being processed without being scratched or polluted on the surface. In the invention, the low-temperature alloy is not used, the production cost is reduced, the production efficiency is improved, the damage to the health of the operators is avoided, and the pollution to the environment is prevented.

Description

technical field

[0001] The invention belongs to the technical field of optical lens production, and relates to the processing of the diopter of the optical lens, in particular to an optical lens white sheet diopter concave processing tool for fixing the optical lens white sheet to a grinding machine and a process method thereof. Background technique

[0002] In the whole process of optical lens production, there is a white diopter concave surface processing process. The purpose is to polish one side of the resin or glass lens into a concave surface with a certain diopter. The specific processing process is to first fix the convex surface of the optical lens white film on the Fix the fixture on a grinding machine, and use the grinding machine to grind the other side of the resin or glass lens into a concave surface with a certain diopter. Among them, the process of "fixing the convex surface of the optical lens white sheet on the fixture" is called "optical lens white sheet u...
