Full-automatic manufacturing device and method for lensed fiber

Abstract

The invention is applicable to the field of optical communication, and provides a full-automatic manufacturing device and method for a lensed fiber. The full-automatic manufacturing device for the lensed fiber comprises a base, a polishing and grinding disk and a machine frame, wherein the polishing and grinding disk is arranged on the base. The polishing and grinding disk is driven by a high-precision motor, an optical fiber clamp and an image sensor are installed on the machine frame, the image sensor is located exactly above the polishing and grinding disk, and a detector and a lens manufacturing device are further arranged on one side of the optical fiber clamp. The polishing and grinding disk is used for polishing and grinding operation of an optical fiber and chamfering, and the detector is used for detecting the optical output value of the polished and ground surface of the optical fiber, and detecting the beam quality in the process that the lensed fiber is manufactured through the lens manufacturing device in real time. According to the invention, due to the fact that the high-precision motor and the detector are adopted, the situation that the polishing and grinding disk bounces in the micron level is guaranteed. Due to the facts that two levels of diamond abrasive paper are used for rough polishing and fine polishing, and error calculation is conducted, the optical value deviation percentage can be within a preset value range, and the accuracy of the lensed fiber is guaranteed.

Description

technical field [0001] The invention belongs to the field of optical communication, and in particular relates to a fully automatic manufacturing equipment and method for lens optical fibers. Background technique [0002] Optical fiber coupling technology is the key technology affecting the optical fiber system, and the lens optical fiber is the key component of optical fiber coupling. The coupling between the light-emitting chip and the optical fiber is essentially a matching problem of the mode field. The more light emitted by the light-emitting chip is coupled into the optical fiber, the more optical fiber communication The farther the distance, the farther the relay distance will be; and the basic way to improve the mode field matching is to add an optical lens to the coupling system to improve the efficiency of optical coupling. The current solution is to directly process the lens at the end of the optical fiber. Get the lensed fiber. [0003] Due to the unstable rotati...
