Problems solved by technology

The surface of the optical glass lens will reduce its light transmittance and refractive index due to pollutants such as oil, dirt, dust, mildew, etc., thereby affecting its performance. Therefore, it is necessary to clean the optical glass lens. However, the existing optical glass cleaning The cleaning effect of the process is not good, and it is impossible to thoroughly clean the oil, stains, dust, mildew and other pollutants on the surface of the optical glass lens

Embodiment 1

[0023] A split process for optical glass laser cutting, comprising the following steps:

[0024] S1: Laser cutting: place the optical glass plate in a laser cutting machine for cutting, and cut out the desired shape of the finished glass plate;

[0025] S2: Put the optical glass plate after laser cutting in S1 into the fixture basket;

[0026] S3: Immerse in the wetting and penetrating solution: Submerge the fixture basket with the optical glass plate in the wetting and penetrating solution for 15 seconds; the wetting and penetrating solution uses fatty alcohol polyoxyethylene ether solution or fatty alcohol polyoxyethylene ether and hydroxide A mixed solution of sodium, and the concentration of sodium hydroxide in the fatty alcohol polyoxyethylene ether solution is controlled at 0.8%.

[0027] S4: Drying with airflow: Slowly pull out the fixture basket with the optical glass plate after soaking from the wetting and penetrating solution, and dry the optical glass plate and th...

Abstract

The invention discloses a splitting process for optical glass laser cutting. The splitting process comprises the following steps: S1, carrying out laser cutting on an optical glass plate; S2, placing the optical glass plate subjected to laser cutting machining in a clamp lifting basket; S3, completely immersing the clamp lifting basket filled with the optical glass plate into wetting penetrating fluid; S4, carrying out airflow blow-drying on the wetted optical glass plate; S5, placing the blow-dried optical glass plate in a plastic packaging box; S6, transferring the plastic packaging box loaded with the optical glass plate into a microwave work station to be subjected to microwave treatment; S7, taking out the finished glass plate and frame waste products in the plastic packaging box; S8, performing polishing/acid pickling for impurity removal on the finished glass plate; and S9, packaging and storing finished products, namely packaging and storing the finished glass plate. Automatic splitting batch production of wafers is realized; splitting efficiency is improved; process use cost is reduced; cleanliness after splitting is guaranteed; and cost of laser splitting equipment of similar processes is reduced.

Description

technical field [0001] The invention relates to the technical field of optical glass processing, in particular to a splitting process of optical glass laser cutting. Background technique [0002] Because the refractive index of optical glass lenses is higher than that of resin lenses, optical glass lenses are thinner than resin lenses at the same degree, and optical glass lenses have better light transmittance and mechanical and chemical properties, and have constant refractive index, physical and chemical properties. Stable performance and other characteristics, and widely used in the production of glasses. The surface of the optical glass lens will reduce its light transmittance and refractive index due to pollutants such as oil, dirt, dust, mildew, etc., thereby affecting its performance. Therefore, it is necessary to clean the optical glass lens. However, the existing optical glass cleaning The cleaning effect of the process is not good, and it is impossible to thorough...
