Device and method for continuously manufacturing optical fiber sensors

Abstract

The invention discloses a device and a method for continuously manufacturing optical fiber sensors. The device comprises an optical fiber drawing mechanism, a bare optical fiber storage and linear velocity regulation mechanism, an optical fiber sensor manufacture mechanism, an optical protection layer coating and curing mechanism and a take-up mechanism. The bare optical fiber storage and linear velocity regulation mechanism stores a bare optical fiber drawn by the optical fiber drawing mechanism temporally, so that the optical fiber sensor manufacture mechanism can process the optical fiber sensors on the static bare optical fiber. Therefore, the optical fiber sensors can be manufactured continuously under the premise that drawing velocity, diameter accuracy, optical performance and mechanical performance of optical fibers are not affected. By means of the device and the method for continuously manufacturing the optical fiber sensors, drawing of the optical fibers, manufacture of the optical fiber sensors, protection coating and curing process of the optical fibers can be completed for one time, and production efficiency is increased greatly. Furthermore, stripping and recoating of protective layers required by manufacture of the optical fiber sensors do not need to be performed in an off-line mode, and effect on characteristics of the optical fiber sensors caused by unevenness of the protective layers can be reduced to the largest extent.

Description

technical field [0001] The invention belongs to the field of optical fiber sensor preparation, and relates to simultaneous online and continuous processing of multiple different types of distributed optical fiber sensors during the optical fiber drawing process. Background technique [0002] Distributed optical fiber sensors have good application prospects. The core preparation technology requires processing optical fiber sensors at different positions on a long-distance optical fiber with the lowest possible loss, so that the optical fiber can have both sensing and signal transmission functions. The traditional method of preparing distributed optical fiber sensors is to use drawn optical fibers to prepare individual optical fiber sensors, and then fuse these sensors in series to form a long-distance distributed optical sensing line. When manufacturing a single optical fiber sensor, chemical solvents or mechanical methods must be used to remove the original resin protective ...
