Abstract

The invention relates to the technical field of optical fiber processing and production, in particular to an optical fiber drawing coating device and a coating method. The optical fiber drawing and coating device comprises: a mold body having an accommodating cavity allowing an optical fiber to pass through; a heat preservation structure which is arranged on the periphery of the mold body in a sleeving mode and provided with a cavity used for containing heat conduction liquid; a first temperature control structure which is arranged in the cavity of the heat preservation structure and comprises a heater, a cooler and a temperature sensor; and a controller which is in signal connection with the first temperature control structure and is used for receiving a temperature signal fed back by the temperature sensor so as to control the heating of the heater or the cooling of the cooler. The invention provides the optical fiber drawing and coating device and the coating method which are uniform in coating and high in product quality.

Description

technical field [0001] The invention relates to the technical field of optical fiber processing and production, in particular to an optical fiber drawing coating device and a coating method. Background technique [0002] Optical fibers play a very important role in modern communication systems. Optical fiber manufacturing is to heat and soften the optical fiber preform at high temperature, then draw it into glass fiber, then coat the surface of the glass fiber with two layers of polymer resin material, and finally form a communication optical fiber after curing. Optical fiber coating is a key link in optical fiber manufacturing. The coating device is one of the core components of optical fiber manufacturing. The coating device will affect the coating concentricity error of the optical fiber, the mechanical strength of the optical fiber, the environmental performance of the optical fiber and the splicing performance. Existing coatings are composed of a mold with a cup body ...
