Abstract
The utility model discloses a high vacuum coating fixture for a hemispherical lens. The high vacuum coating fixture comprises a cylindrical fixture body, wherein a stopping baffle plate is arranged at the edge of the top of the fixture body. The high vacuum coating fixture is characterized in that a blocking sleeve is arranged at the inner side of the bottom of the fixture body, the inner side surface of the blocking sleeve is of a spherical surface structure, and the diameter of the spherical surface of the blocking sleeve is slightly less than the outer diameter of a coated lens. The high vacuum coating fixture has the advantages of simple structure and strong practicability, and is easy to machine and produce and convenient to operate, the lens can be freely assembled and disassembled, the coating quality is improved, and the scrap rate is lowered.
Description
Technical field
The utility model relates to a kind of fixture, specifically, relates to a kind of high vacuum coating fixture of packaged lens.Belong to opticinstrument part manufacture field.
Background technology
The hemisphere optical lens is the spherical lens that half angle of divergence is 90 degree, and this optical element is widely used in ultrashort focal length projector, in the modern photoelectron instruments such as ultra-large vision field video recorder and monitor, is each quasi-instrument center heart key part.For performance and the function that improves instrument, need to be coated with various specific films as anti-reflection film, reflectance coating, infrared film, polarizing coating, conducting film etc. to the optical element surface.Need to use coating clamp in coating process, whether suitable quality and yield rate and the damage condemnation factor that directly affects plated film of fixture.
Between coating clamp used and lens, be at present to contact, make eyeglass weight drop on a little line point fully and go up, be easy to scratch lens surface.Simultaneously eyeglass needs heat treatment, and in the hemisphere eyeglass, thick and external diameter differs too large, and the thermal expansion that eyeglass produces is also irregular, easily causes eyeglass stuck or burst and cause plated eyeglass to be scrapped at fixture Inner.
Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this utility model is to provide a kind of packaged lens vacuum plating unit clamp simple and easy, practical, easy to loading and unloading.
The technical solution adopted in the utility model is:
The high vacuum coating fixture of packaged lens, comprise the tubular chuck body, be provided with lock plate on the top of described chuck body, the bottom inside of described chuck body is provided with and stops cover, describedly stop that the medial surface of cover is the spherical structure, describedly stop that the diameter that overlaps spherical is slightly less than the external diameter of institute's plated film lens.
Describedly stop that the diameter that overlaps spherical is than the little 0.5-1.5um of the external diameter of institute plated film lens.
The utility model stops that to chuck body cover is improved, and will put contact and make the face contact into, and the stress point of eyeglass is enlarged, and increases the smoothness of plated film, prevents that eyeglass is scratched or bursts, and improves the quality of institute's plated film lens.
The utility model has the advantages that: simple in structure, be easy to processing and manufacturing, easy to operate, practical, eyeglass loads and unloads freely, and coating quality improves, reduces condemnation factor.
The accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is structural representation in the utility model use procedure.
Wherein: 1, chuck body, 2, lock plate, 3, stop cover, 4, stop the medial surface of cover, 5, eyeglass.
Embodiment
As depicted in figs. 1 and 2, the high vacuum coating fixture of packaged lens, comprise tubular chuck body 1, be provided with lock plate 2 on the top of chuck body 1, be provided with and stop cover 3 in the bottom inside of chuck body 1, lock plate plate 2, stop that cover 3 and chuck body 1 are an one-piece construction, the medial surface 4 that stops cover is the spherical structure; In order to make to need the plated film lens marginal surface to be blocked less as far as possible, can guarantee again to need the not landing in fixture of plating eyeglass, the diameter that will stop the spherical of cover is designed to be slightly less than, and stops that the diameter of spherical of cover is than the little 0.5-1.5um of the external diameter of institute plated film lens 5.
Claims (3)
1. the high vacuum coating fixture of packaged lens, comprise the tubular chuck body, be provided with lock plate on the top of described chuck body, it is characterized in that: the bottom inside of described chuck body is provided with and stops cover, describedly stop that the medial surface of cover is the spherical structure, describedly stop that the diameter that overlaps spherical is slightly less than the external diameter of institute's plated film lens.
2. the high vacuum coating fixture of packaged lens according to claim 1 is characterized in that: describedly stop that the diameter that overlaps spherical is than the little 0.5-1.5um of the external diameter of institute plated film lens.
