Method of reducing optical fiber coloring unevenness and apparatus thereof

Abstract

The invention relates to a method of reducing optical fiber coloring unevenness and an apparatus thereof. The method comprises the following steps that before an optical fiber is assembled, a laser is arranged between a pay-off disc and an eye film die holder; the laser is arranged at a preset center line and irradiates towards an eye film die hole along the set center line; after an eye film is installed, a light spot condition projected by the laser on the eye film is recorded and whether the installed eye film is usable is determined; power of original UV lamps is increased and a quantity of the UV lamps is reduced, and two guide wheels are additionally installed at positions where the UV lamps are removed. The method and the apparatus have advantages that on one hand, through confirming the size of the light spot, whether a center of the light spot is deviated is observed at any time so as to ensure that the eye film is installed on the place; on the other hand, through reducing an optical fiber free length and additionally installing the guide wheels, optical fiber jitter is reduced and adverse factor generation is decreased so as to solve a problem that optical fiber coloring is uneven.

Description

technical field [0001] The invention relates to the field of optical fiber manufacturing, in particular to a method and device for reducing uneven coloring of optical fibers. Background technique [0002] Reduce the eccentricity problem in the production process. Since the diameter of the optical fiber is very small and only 0.25mm, it is not so easy to see whether it is eccentric with the naked eye. Generally, we hang the center line regularly, but at the same time, the colored eye mask needs to be removed and cleaned frequently before installation. Going up, sometimes cleaning 10 times a day, whether the installation is in place after each installation, whether it is in the center, the staff can not be sure, can only try their luck, and it is impractical to hang the center line after each installation. [0003] Uneven coloring of optical fiber is the most common defect in the optical fiber coloring process. Generally, there are three main reasons for uneven coloring. Firs...

AI Technical Summary

Problems solved by technology

First, the center line is offset, so that the coloring of the optical fiber cannot be coated with colored resin on some surfaces, resulting in uneven coloring of the optical fiber; second, the air tightness of the glue tank is not good, and air leakage leads to unstable glue supply pressure. There is no coloring phenomenon intermittently; thirdly, the static electricity of the optical fiber is too large, which is prone to jitter and intermittent coloring unevenness
