Tool used for optical fiber capillary tube film coating

Abstract

The invention discloses a tool used for optical fiber capillary tube film coating. The tool is characterized by comprising a tool body; the tool body is of a cuboid structure and is composed of a baseand a cover plate covering the base; the tool body is provided with multiple product grooves matched with optical capillary tubes in appearance in the positions of covering faces of the base and thecover plate; the multiple product grooves are formed in the length direction of the tool body; each product groove is provided with an optical fiber limiting end and a capillary tube limiting end connected with the optical fiber limiting end; the optical fiber limiting ends are sealed in the tool body; and the limiting ends of the capillary tubes are opened and communicate with external media. Bymeans of the tool used for optical fiber capillary tube film coating, the optical fibers are not likely to be bent and fractured during film coating of the optical capillary tubes, the product qualityof the optical capillary tubes is improved, the tool can be used for batched film coating, the film coating efficiency of the optical capillary tubes is improved, and the film coating requirement forcapillary tube tail fibers is met.

Description

technical field [0001] The invention relates to the technical field of optical product films, in particular to a tool for coating an optical fiber capillary tube. Background technique [0002] Coating technology is widely used in the industry, and is generally used in the metal processing industry, semiconductor industry, and communication fields. With the development of optical coatings, the application range of optical coatings in the field of communication is becoming wider and wider. Coating refers to coating single-layer or multi-layer thin films on the surface of optical components by physical or chemical methods, using the interference of incident, reflected and transmitted light at the film interface to achieve focusing, collimation, filtering, reflection and refraction effects. The coating process of optical products is as follows: first, install the optical product to be coated on the coating jig, and the coating jig is placed on the umbrella stand in the cavity o...

Problems solved by technology

Due to the current lack of special tooling for optical fiber capillary coating, the coating tools used are all frame structures, and the coated products are directly placed in the frame of the tooling (such as figure 2 ), the existing tooling cannot meet the coating requirements of the capillary tail fiber, and the optical fiber is prone to bending or even breaking when coating the fiber capillary, which seriously affects the product quality of the fiber capillary
