An online gluing device for making optical fiber rings based on capillary action

Abstract

The invention relates to an on-line sizing device for making optical fiber loops based on capillary action, comprising a mounting base, a glue pool, a glue-sizing member forming a vertical slit, and a glue pool cover; the glue pool is placed on the mounting base. On the installation platform at the upper end of the seat, the glue injection nozzle at the upper end of the installation base is sealed and inserted with the glue injection nozzle insertion hole set at the bottom of the glue liquid pool, and there is a glue injection channel connected between the glue injection nozzle and one side of the installation base. It is connected to the external glue injection system through the joint and the pipeline; the installation groove at the lower end of the installation base is embedded with an electric heating plate, and the installation base is installed with a temperature sensor at the position of the glue injection nozzle; The liquid level observation window is installed with a transparent baffle plate, and a photoelectric liquid level sensor is provided outside the glue liquid pool at the position facing the liquid level observation window; The opening of the cover protrudes to form a sizing portion for the optical fiber to pass through. The device has the advantages of simple structure, convenient gluing and online gluing.

Description

technical field [0001] The invention belongs to the technical field of making optical fiber rings, and in particular relates to an online gluing device for making optical fiber rings based on capillary action. Background technique [0002] The optical fiber ring is a ring-shaped optical sensitive element formed by winding optical fiber and solidified by glue. It is the core of optical fiber gyroscopes, optical fiber current transformers and other instruments. The pros and cons of its production technology directly determine the performance of the aforementioned instruments and meters. Glue is one of the two materials that make up the optical fiber ring (the other is the optical fiber). Its function is to ensure the position of the optical fiber in the optical fiber ring, so that the ring product can obtain stable and reliable precision performance. Therefore, the glue sizing technology is an indispensable part of the optical fiber ring manufacturing technology. [0003] At...

Problems solved by technology

[0003] At present, there are mainly two types of optical fiber ring sizing technology at home and abroad: offline sizing and online sizing. Both solutions have their own advantages: offline sizing is suitable for mass-produced ring products, but because of its The position of the optical fiber in the product will be disturbed during the gluing process, so it is only suitable for ring products with low precision performance; online gluing just makes up for this disadvantage, and the gluing process will not affect the position accuracy of the optical fiber in the product, but Compared with the former, it takes relatively longer man-hours and has higher requirements on the sizing device, so it is suitable for medium and high-precision ring products
