Plastic light guide fiber end face processing method, apparatus, cutting blade and connecting method

Abstract

A plastic optical fiber end surface processing method, a processing apparatus for the method, a cutter for use in the method, and a plastic optical fiber connecting method are provided. The processing method is that at least the core part of the end face of the plastic optical fiber is cut to be formed into a hemisphere face with a half circular cutting blade. The processing apparatus includes: a motor; a cutting blade connected with connecting component or directly to the driving shaft of the motor; a holder having a through hole for inserting the cutting blade into the middle portion of the through hole; a cutter inserted from one side into the through-hole of the holder for cutting at least the core part of the end face of the plastic optical fiber with rotating cutting blade. The invention is capable of processing the plastic optical fiber to be not only convex semi-spherical surface but also concave semi-spherical surface and arbitrary profile according to the change of the cutting blade shape.

Description

technical field [0001] The present invention relates to a method for processing the end face of a plastic optical fiber, which is a method for processing the end face of a plastic optical fiber (hereinafter simply referred to as an optical fiber) such as a convex or concave hemispherical surface, and its processing Devices, cutting blades, and optical fibers are connected to each other, optical fibers are connected to machines, and optical fibers are connected to connecting devices such as connectors, etc. Optical fiber connection methods, especially light guides with little light loss at the connecting part fiber connection method, Background technique [0002] In the past, the method of processing the end surface of the optical fiber into a hemispherical surface was usually a method of processing the end surface after heating. For example, there is a method of keeping the optical fiber in a vertical state, heating its tip with a high-temperature heat source such as a flam...

AI Technical Summary

Problems solved by technology

[0006] However, the above-mentioned conventional processing apparatus for processing the end face of an optical fiber by heating can be applied to the formation of a convex hemispherical surface, and there is a problem that other shapes including a concave hemispherical surface cannot be formed.
