Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical crystal processing, in particular to a vacuum coating processing device for optical crystal processing. Background Art
[0002] Optical crystals are used as optical dielectric materials, primarily in the manufacture of ultraviolet and infrared windows, lenses, and prisms. Single crystals are the most commonly used optical crystals due to their high crystal integrity, light transmittance, and low input loss. Optical coating is the process of applying one or more layers of metal (or dielectric) thin film to the surface of an optical component. The purpose of coating an optical component is to reduce or increase light reflection, beam splitting, color separation, filtering, and polarization.
[0003] After searching, the patent publication number CN217026055U discloses a patent named "A Vacuum Coating Processing Device for Optical Crystal Processing". The technical problem it aims to solve is that only one side of the optical crystal sheet can be coated, or the outer wall of the optical lens will be blocked by the fixture during spraying, resulting in uneven coating, which will affect the processing speed and quality. By first pulling the pull rod on each fixing hole away from each other, the pull rod drives the splint to move, and then the optical crystal is placed in the fixing hole. At this time, the reaction force of the spring in the compressed state can push the splint to fix the optical crystal. When coating, , start the second motor, so that the rotating shaft drives the fixed disk to rotate 90 degrees, so that it faces the coating emission source, so that the coating emission source can spray coating the optical crystal, and at the same time start the first motor, so that the gear drives the rotating disk to rotate, so as to achieve the effect of uniformly spraying the optical crystal. When the coating of one side of the optical crystal is completed, start the second motor again, so that the rotating shaft drives the fixed disk to rotate 180 degrees, thereby turning the rotating disk over, so as to achieve the effect of turning over the optical crystal for coating; but there are still the following disadvantages that need to be solved: the rotating disk is unstable during the process of rotating and turning the optical crystal, which may cause the optical crystal to fall.
