Problems solved by technology

[0005] Optical lenses are optical glass lenses, but after the optical lens is ground, there will be a 2-3mm crack layer, and polishing is required to eliminate it. The current polishing method is cumbersome and inefficient, and it is difficult to ensure the surface shape and polishing accuracy of the lens. After polishing, the optical lens needs to be cleaned, but the current cleaning method, if the cleaning is not clean enough, there will be residues, and the cleaning method often cannot meet the latest technology and engineering requirements

Embodiment 1

[0034] The technical solution adopted in this specific embodiment is: the polishing method of the optical lens is characterized in that it comprises the following steps:

[0035] Step 1. Prepare the polishing solution; prepare the polishing solution required for optical lens polishing in advance, and the polishing solution contains the following raw materials in parts by weight: 75 parts of water, 13 parts of cerium oxide, 0.5 part of hydrofluoric acid, and 0.5 part of nitric acid , 0.5 parts of zinc nitrate, 2 parts of silicon dioxide, 2 parts of alkane polyglycol ether;

[0036] Step 2, prepare the polishing device; use the correction mold to trim the polishing pad of the device, and clean the polishing pad; fix the polishing pad on the polishing pad base;

[0037] Step 3, install the polishing liquid; place the prepared polishing liquid in the polishing liquid circulation cylinder of the polishing device;

[0038] Step 4, install the optical lens; place the optical lens to...

Embodiment 2

[0060] The difference between this embodiment and Example 1 is that the polishing liquid contains the following raw materials in parts by weight: 80 parts of water, 18 parts of cerium oxide, 1 part of hydrofluoric acid, 1.5 parts of nitric acid, 1.5 parts of zinc nitrate, two 3 parts of silicon oxide, 3 parts of polyglycol ether. Other compositions and connections are the same as in Embodiment 1.

Embodiment 3

[0062] The difference between this embodiment and Example 1 is that the polishing liquid contains the following raw materials in parts by weight: 78 parts by weight of water, 15 parts by cerium oxide, 0.8 parts by weight of hydrofluoric acid 0.8 parts of nitric acid, 1 part of zinc nitrate, 2.5 parts of silicon dioxide, and 2.5 parts of polyglycol ether. Other compositions and connections are the same as in Embodiment 1.

[0063] After adopting the above technical scheme, the beneficial effects of the present invention are: the polishing method of the present invention is simple to operate, high in efficiency, and can ensure the surface shape and polishing accuracy of the lens; the cleaning method of the present invention improves the cleaning effect of the optical lens, especially can remove the lens The residue on the cylindrical surface (non-polished surface), due to the addition of acidic cleaning solution, neutralizes the alkaline substances attached to the surface of the...

The method for cleaning the optical lens is characterized by comprisingthe following steps of firstly, cleaning with an organic solvent; secondly, cleaning with water; thirdly, cleaning with a basic solution; fourthly, cleaning with water; fifthly, cleaning with an acidic solution; sixthly, cleaning with water; seventhly, ultrasonic cleaning; eighthly, cleaning with alcohol; ninthly, cleaning with water; and tenthly, vacuum drying. The method for polishing and cleaning the optical lens has the beneficial effects that the polishing method is simple in operation and high in efficiency; the facial form and polishing accuracy of the lens can be guaranteed; and the cleaning effect of the optical lens is improved by the cleaning method.

Description

technical field [0001] The invention relates to the technical field of lens processing, in particular to methods for polishing and cleaning optical lenses. Background technique [0002] The glass originally used to make lenses is the bump on ordinary window glass or wine bottles, which is shaped like a "crown", hence the name crown glass or crown glass. The glass at that time was extremely uneven and foamy. In addition to crown glass, there is another flint glass that contains more lead. Around 1790, Frenchman Pierre-Louis Junard discovered that stirring glass sauce could make glass with uniform texture. In 1884, Ernst Abbe and Otto Schott of Zeiss Company founded the Schott Glass Factory (Schott Glaswerke AG) in Jena, Germany, and developed dozens of optical glasses within a few years, among which high refractive index The invention of the barium crown glass is one of the important achievements of SCHOTT Glassworks. [0003] Optical glass is mixed with high-purity oxide...
