Abstract
A kind of combined optical element mask clamping fixture comprising: chuck body is provided with the circular clamp of square hole centered on the chuck body；For in the optical element film coated mask plate for blocking the optical element in the process；With several fixture items for being detachably mounted to the mask plate in the chuck body.A kind of mask clamping fixture disclosed in the utility model, it is applied in combination by using dismountable mask plate and the circular die with square hole, it solves traditional coating clamp and is not easy to realize the problem of optical element surface different zones are coated with different film layers or different zones are coated with film layer and are not coated with film layer.In addition, the not super 0.5-1mm of bottom Mask portion thickness of mask plate, not will cause the problem of film layer is coated with middle empty film.The processing is simple for this mask clamping fixture, and performance is stablized, and chuck body and fixture item are also reusable, save the cost, the requirement being coated with particularly suitable for high-volume optical element surface exposure mask.
Description
Technical field
The utility model relates to a kind of optical element mask clamping fixtures.Belong to optical element processing and film plating field.
Background technique
When for optical element surface plated film, it is frequently encountered optical element surface different zones and needs to be coated with different film layers
Or different zones the case where being coated with film layer and not being coated with film layer.Such as: in the optical element surface only plating in a half range
Film, another half range not plated film.The method for handling the above problem in the prior art is the fixture of direct engraving complexity, this method
Though can satisfy the production requirement of Partial coatings, this fixture has processing, and time-consuming, fixture is not easy to be processed, fixture repeats benefit
The problems such as poor with rate, increases crystal production cost.
It is complicated in the prior art, being processed for coating clamp, the problems such as can not reusing, need a kind of novel clamp
Tool is to solve the above problems.
Utility model content
In order to solve above-mentioned the problems of coating clamp in the prior art, the utility model provides a kind of combined light
Element mask clamping fixture is learned, by efficiently solving using dismountable fixture item and mask plate are arranged on existing coating clamp
The problems such as fixture production is complicated, and recycling rate of waterused is low.
Technical solution provided by the utility model are as follows:
A kind of mask clamping fixture, comprising:
Chuck body is provided with the round coating clamp of square hole centered on the chuck body；
For in the optical element film coated mask plate for blocking the optical element in the process；With
Several fixture items for being detachably mounted to the mask plate in the chuck body.
Further, the catercorner length in the square hole is less than the diameter of the circular clamp.
Further, the mask plate is rectangular half hollow out of aluminium sheet one, the other half is the bottom plate with a thickness of 0.5-1mm.
Further, the end of the hollow-out part of the mask plate is provided with the first for fixing the optics of wide 0.5-1mm
The flanging of part.
Further, the fixture item is the rectangular slab with setting thickness, and both ends are provided with for by the fixture
Item is fixed on the card slot in the circular clamp.
Further, the fixture length is 10-20mm longer than the side length of the square hole.
Further, the card slot depth is 5-10mm.
Further, the fixture item is provided with for the fixture item to be fixed on the circular clamp at two side bayonet slots
On fixed structure.
Further, the fixed structure includes being arranged on fixture item, and be located at threaded hole and screw at card slot.
Further, flanging is provided in two long sides of the fixture item, the flanging width is 0.5-1mm.
A kind of mask clamping fixture disclosed in the utility model, by using dismountable mask plate and the circle for having square hole
Die assembly uses, and solves traditional coating clamp and is not easy to realize that optical element surface different zones are coated with different film layers, or not
The problem of being coated with film layer with region and not being coated with film layer.In addition, the not super 0.5-1mm of bottom Mask portion thickness of mask plate, no
It will cause the problem of film layer is coated with middle empty film.The processing is simple for this mask clamping fixture, uses stabilization, common round square hole coating clamp
And fixture item is also reusable, save the cost, the requirement being coated with particularly suitable for high-volume optical element surface exposure mask.

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, 2, the mask clamping fixture of the utility model includes: chuck body 1, fixture item 2 and mask plate 3.
As shown in Fig. 2, chuck body 1 is to be provided with the circular clamp of square hole 4, chuck body 1 can be by existing circle
Square hole is opened on clamp to be made, and can also directly be processed.Square hole 4 is for placing optical element to be coated.Square hole 4
Diagonal line should be less than the diameter of circular clamp 1.
As shown in Figure 3,4, fixture item 2 is with the rectangular strip board of setting thickness, and both ends, which have been provided with, to be used for
The card slot 5 fixture item 2 being fixed in circular clamp 1.The length of fixture item 2 is greater than the side length of square hole 4, it is preferred that its
Length is 10-20mm longer than the side length of square hole 4.In order to which mask plate 3 is firmly fixed, fixture item 2 further includes fixed structure,
Fixed structure includes the threaded hole 7 being arranged at card slot 6 and the matched fastening screw used.Threaded hole 7 can be such as 3 figure institutes
Show, is only arranged in the side of card slot 5, can also be respectively provided in the two sides of card slot 5.Preferably, the size of threaded hole 7 is M3.Certainly,
