Abstract

The invention creatively provides a wire penetrating system and method for optical fiber drawing. The wire penetrating system comprises a prefabricated rod, a drawing tower body, a heating furnace, acooling pipe, a coating device, a curing lamp box, a measuring device, a traction mechanism and a main controller; the prefabricated rod is fixed at the top end of the drawing tower body and is coaxial with an inlet of the heating furnace; the heating furnace is arranged at the upper part of the wire drawing tower body; and a cooling pipe is arranged below the heating furnace and is used for cooling bare optical fibers. According to the invention, an original wire penetrating method is changed, and after optical fiber drawing is interrupted, original mold unloading and cleaning operation is not carried out, so that waste of a large amount of manpower, material resources and labor hours for cleaning a mold is avoided, meanwhile, various problems of an optical fiber coating layer in an optical fiber production speed-increasing process are reduced, cost is reduced for enterprises, and certain contributions are made to improving the product percent of pass.

Description

technical field [0001] The invention belongs to the field of optical fiber drawing, and in particular relates to a threading system and method based on the optical fiber manufacturing process. Background technique [0002] In recent years, with the large-scale deployment and application of my country's 5G network, the demand for optical fiber has increased significantly, and major optical fiber manufacturers have expanded their production capacity. Since the WET ON WET (hereinafter referred to as WOW) coating method has the characteristics of high fiber drawing production speed, this coating method is preferred, but the WOW coated fiber drawing production technology will introduce fiber Coating layer defects, coating layer bubbles, and coating layer unevenness. The present invention changes the original wire threading method. After the optical fiber wire drawing is interrupted, the original mold unloading cleaning operation is not performed. While avoiding the waste of a lo...
