Online regulating system of optical fiber drawing chuck

Abstract

The invention discloses an online regulating system of an optical fiber drawing chuck. The online regulating system comprises the chuck, a drawing furnace and a coating die which are sequentially arranged from top to bottom and is characterized in that the top of a prefabricated rod is suspended on the chuck, the body of the prefabricated rod is placed in the drawing furnace, subjected to high-temperature melting and drawn into an optical fiber, the optical fiber penetrates the coating die for coating, the transverse positions of the chuck are regulated through a first linear drive mechanism and a second linear drive mechanism which are located on a transverse direction and are perpendicular to each other, and a concentricity detecting device is arranged between the drawing furnace and the coating die. The online regulating system is simple in structure, high in applicability, capable of conveniently and flexibly regulating optical fiber positions online to allow the optical fiber to be concentric with the central position of the coating die, capable of increasing coating evenness and consistence, capable of guaranteeing coating quality, capable of avoiding defective conditions such as fiber breaking, capable of greatly increasing production yield, capable of guaranteeing production quality, capable of lowering production loss and capable of increasing production economic benefits.

Description

technical field [0001] The invention relates to the technical field of optical fiber drawing equipment, in particular to an online adjustment system for optical fiber drawing clamps. Background technique [0002] The preform is vertically fed into the drawing furnace through the feeding chuck. The preform is melted at high temperature and then drawn into a filament. Under the action of the drawing tension, it shrinks rapidly and becomes thinner to become a bare optical fiber. The high-temperature bare optical fiber coming out of the furnace enters the cooling system. After cooling down, when the microcracks on the surface of the bare optical fiber have not been affected by moisture in the air, etc., it needs to be coated quickly to protect the surface of the optical fiber. In the coating system, the surface of the optical fiber is coated with resin coating, and then enters the curing process. The system strengthens the anti-stretching and bending capabilities of the bare opt...
