Adjustable-type optical coating fixture

Abstract

The invention discloses an adjustable-type optical coating fixture, and relates to the field of optical coating. The problems that an existing coating fixture is only used for a substrate to be coated of the single size and single shape and is not applicable when the size and shape of the substrate to be coated are changed are solved. The adjustable-type optical coating fixture comprises a connecting member, a fixed guiding member with a plurality of T-shaped grooves, sliding members installed in the T-shaped grooves in a one-to-one correspondence mode and in clearance fit with the T-shaped grooves, and clamping members. Each clamping member comprises three supporting frames, a lead screw fixed to the upper supporting frame, a sliding block installed on the lead screw in a sleeving mode and a flexible portion fixed to the sliding block. A protruding structure on the edge of each upper supporting frame makes contact with the upper surface and the side face of the substrate to be coated, and the upper surface of each flexible portion makes contact with the lower surface of the substrate to be coated. The sliding members are connected with the lower supporting frames through locking screws, and the T-shaped grooves of the fixed guiding member are tightly clamped by the sliding members and the lower supporting frames through the locking screws. According to the adjustable-type optical coating fixture, clamping on substrates to be coated of different sizes and different shapes is achieved, the coating period is shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of optical coating, in particular to an adjustable optical coating fixture. Background technique [0002] Vacuum coating technology is to use physical and chemical means to coat the surface of solid materials with a layer of coating with special properties, so that the surface of solid materials has wear resistance, high temperature resistance, corrosion resistance, oxidation resistance, radiation protection, electrical conductivity, magnetic conductivity, and insulation. And decoration and many other superior properties than the solid material itself. At present, vacuum coating technology has been widely used in aviation, aerospace, electronics, information, machinery, petroleum, chemical industry, environmental protection, military and other fields. [0003] When using a vacuum coating machine to coat a thin film on the surface of the substrate 5 to be coated, it is necessary to use a clamp to hold the su...
