Problems solved by technology

Large-scale spherical mirrors mainly use silicon glass as the mirror material, which is generally processed by heating and softening the silicon glass formed by the mold on a mirror grinding machine through rough grinding, fine grinding and polishing; this manufacturing method has a long cycle and high cost. , the product weight is large
At present, the virtual image display system for simulators in the world mainly uses film negative pressure to form a large spherical mirror, which is to stick the plastic film coated with reflective film on the spherical mirror seat of composite material raised around it, and stretch the plastic film with negative pressure equipment. It is a spherical surface; the negative pressure equipment of this large spherical mirror needs to work continuously for a long time to maintain the spherical shape. After a long time, the aging surface of the plastic film will deteriorate. The reflective film layer of the plastic film is not easy to clean after collecting dust, and the maintenance is poor

Embodiment Construction

[0022] In order to better illustrate the purpose and advantages of the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Polymerized carbon-plastic composite large-scale spherical mirror, the radius of curvature R is 3000 mm, the thickness of the mirror substrate is 20 mm, the geometric size is 40 degrees for the vertical center angle, and 36 degrees for the horizontal center angle. The spherical mold substrate 1 of R3000 is first thermally formed with 20 mm thick silicon glass, and the convex surface of the spherical mold substrate 1 is ground and polished to an optical level on a mirror grinder, with an optical error of 2 to 5 apertures. The mirror seat 2 of the spherical reflector is a composite structure of pre-impregnated epoxy resin carbon fiber cloth and aluminum honeycomb. Five layers of pre-impregnated carbon fiber cloth, five layers of pre-impregnated glass fi...

Abstract

The present invention relates to a pouring carbon plastic large spherical reflection lens and a production method, belonging to the technical field of optical display. The pouring carbon plastic large spherical reflection lens comprises a lens seat, a reflection lens substrate and a reflection film layer. The reflection lens substrate and the lens seat are bonded adsehively, and the reflection film layer is plated to the reflection lens substrate through a plating machine. The lens is made of glass, metal or composite materials. The reflection lens substrate is made of organic glass or other suitable optical plastic, and the convex surface fits the concave surface of the lens seat and is bonded and cured on the lens seat concave surface. Compared with a glass spherical reflection lens, the carbon plastic large spherical reflection lens has the advantages of light weight, short manufacturing cycle, low cost and good rigidity, compared with a film negative pressure formation large spherical reflection lens, the carbon plastic large spherical reflection lens has the advantages of high strength, a long life, good optical performance and maintainability. The simulation training requirements of a general aircraft, a large aircraft and other large equipment can be satisfied by a 1600-4000 mm large curvature radius. The pouring carbon plastic large spherical reflection lens is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to a pouring polycarbonate composite large-scale spherical reflector and a manufacturing method thereof, belonging to the technical field of optical display. Background technique [0002] The virtual image display system uses a large spherical mirror as an optical imaging element. Large-scale spherical mirrors mainly use silicon glass as the mirror material, which is generally processed by heating and softening the silicon glass formed by the mold on a mirror grinding machine through rough grinding, fine grinding and polishing; this manufacturing method has a long cycle and high cost. , The product is heavy. At present, the virtual image display system for simulators in the world mainly uses film negative pressure to form a large spherical mirror, which is to stick the plastic film coated with reflective film on the spherical mirror seat of composite material raised around it, and stretch the plastic film with negative pressure e...
