Problems solved by technology

[0005] 1. The protective paint has poor high temperature resistance and is easy to soften. Therefore, it is necessary to control the temperature when putting it on the plate. Melting the wax, the wax and the optical parts are not bonded firmly, and there may be a danger of the optical parts moving or even falling
[0006] 2. The surface smoothness of the polished surface of optical parts is a very important indicator, but it is necessary to use a brush to smear to form a uniform and complete protective paint layer during the painting process. For the polished surface, if the force is not used properly, it will make The tip of the writing brush forms scratches on the surface of the polished surface, destroying the smoothness of the polished surface of the optical parts, resulting in rework or even waste of the optical parts
[0007] 3. The cleaning process of the protective paint is cumbersome. It is necessary to soak the optical parts in alcohol for many times and wipe them repeatedly, which will also reduce the yield of optical parts during the operation.
[0008] 4. During the process of using wax paint, wax marks may be formed on the surface of optical parts due to the inconsistent thickness or uniformity of the application, and alcohol will be used in the process of preparing protective paint. Alcohol contains a certain proportion of water, which may be on the optical parts. imprint on the surface

Embodiment 1

[0036] Optical parts to be processed: germanium squares with a length, width and height of 215*135*12mm. The germanium squares include the opposite polishing surface and protective surface. Fix it on the fixture, choose a PET single-sided blue tape of appropriate width according to the size of the polishing sheet, cover the entire protective surface with PET tape to form a protective film, and remove the excess PET tape; the paste process is carried out slowly to prevent Bubbles are generated; upper plate: Put the protective film of the germanium square sheet with the protective film facing upward, then heat the seal ball to 110°C, and under the action of external force, stick the seal ball to the germanium square sheet with the protective film until Remove the external force after the wax ball cools and sticks firmly; then heat the adhesive film, and under the action of external force, stick the high-temperature adhesive film on the wax ball until the wax ball and the adhesive...

Abstract

The invention relates to a polishing method for optical elements. The polishing method for the optical elements is characterized in that protection paint in the prior art is replaced by a PET adhesivetape; the PET adhesive tape is easily available; a protection surface is protected; an optical element is fixedly connected with an adhesive mould; after polishing is finished, the PED adhesive tapecan be easily torn off without residual glue; and various technical problems caused by smearing the protection paint can be avoided.

Description

technical field [0001] The invention relates to the field of polishing optical parts, in particular to a polishing method for optical parts. Background technique [0002] For high-precision, ultra-small or ultra-large optical parts, classical polishing methods are generally used for polishing. The classical polishing method has the following main steps: upper plate, grinding, rough polishing, fine polishing, and lower plate. Mounting is a key process of polishing, which refers to bonding the optical parts to the plastic mold. The mounting process must ensure that no mechanical damage will be caused to the surface of the parts, and there must be sufficient bonding strength to withstand the processing. pressure and speed. The common way of putting on the plate is wax ball glue plate. First, the wax ball is melted and stuck to the parts at high temperature, and then the rubber mold is heated to the temperature that can melt the wax ball. The ball keeps the optical parts fixe...
