Optical filter coating regulating unit

Abstract

One kind of film filling device used for light filter. It is used together with a basal board, which has a core hole, a outer round edge, a surface to be filled and a surface to be press. The film filling device comprises at least one film filling covering plate, at least one film filling baffle and a steadily locked orientating device. The film filling covering plate possesses at least one first vacancy section; the film filling baffle possesses at least one second vacancy section corresponding the first vacancy section; the steadily locked orientating device is to orientate the basal board, the film filling covering plate and the film filling baffle, to make the second vacancy section and the first vacancy section splice connected, and to make the film filling baffle come into contact with the film filling covering plate. Then make the film filling covering plate joint close with the surface to be filled. The dyeing materials can orderly get through the second and first vacancy section connected by splicing, and cling to the surface to be filled corresponding the bound of the first vacancy section which forms a color section. This invention can make the whole basal board of light filter accurately forms film filling color section in its different positions.

Description

【Technical field】 [0001] The invention relates to a coating jig, in particular to a coating jig for an optical filter that can be used for multi-color coating on an integral optical filter substrate. 【Background technique】 [0002] Such as figure 1 As shown, an existing optical projection device (US Pat. No. 5,868,482) includes a color wheel set 1 , a projection light source 2 , an image generating device 3 , an optical projection system 4 , and a screen 5 . Referring to Fig. 2, the color wheel set 1 has a motor 101, a carrier 102 installed on the spindle of the motor 101, an adhesive layer 103 coated on the carrier 102, and three glued on the adhesive. On the adhesive layer 103, there are circular fan-shaped filters 104 that can be joined together, and a clamp ring 105 that can clamp and cover the bonded areas of the fan-shaped filters 104 . Thereby, when the motor 101 drives the fan-shaped filters 104 to rotate, the light projected by the projection light source 2 can pa...

AI Technical Summary

Problems solved by technology

[0005] Since the fan-shaped filters 104 are grouped and fixed on the carrier 102 instead of integrally made into a ring shape, the fan-shaped filters 104 are prone to dynamic balance and stress when rotating at high speed. In addition, these fan-shaped filters 104 need to be coated, colored and cut from different single pieces 6 before they can be bonded and assembled on the carrier 102. In this way, not only the production is troublesome and inconvenient, but also , the stability and precision of these fan-shaped filters 104 are not easy to control
