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...

Examples

Embodiment Construction

[0024] The solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 , the method for reducing the uneven coloring of the optical fiber of the present invention includes: the step of making the optical fiber coloring uniform by reducing the eccentricity of the optical fiber: before assembling the optical fiber, a laser is set between the pay-off reel and the eye mask mold base, and the laser is located Pre-set center line, and along the set center line to irradiate the eye mask mold hole, after installing the eye mask, record the light spot situation projected by the laser on the eye mask, when the distance between any two points on the light spot is within the set When it is within the value range of , it is considered that the concentricity of the eye mask installation is good, and the optical fiber can be assembled. The steps to make the optical fiber color uniform by reducing the jitter of ...
