Device and method for pretreatment of end face of small optical fiber ceramic ferrule

Abstract

The invention discloses a device and method for pretreatment of an end face of a small optical fiber ceramic ferrule. The device comprises an automatic loading-unloading system, a workpiece clamping main shaft system and a grinding main shaft system, wherein the automatic loading-unloading system is provided with an feeding hole and an discharge hole which are used for transmitting the optical fiber ceramic ferrule to the discharge hole, the workpiece clamping main shaft system is disposed at the lateral side of the discharge hole and the grinding main shaft system is disposed at one side, inthe horizontal direction, of the workpiece clamping main shaft system; the workpiece clamping main shaft system comprises a workpiece clamping assembly, and the workpiece clamping assembly is used forclamping the optical fiber ceramic ferrule which is transmitted to the discharge hole; and the grinding main shaft system comprises a horizontal motion platform and a grinding assembly, the grindingassembly is connected to the horizontal motion platform, and the horizontal motion platform is used for driving the grinding assembly to move along the horizontal direction so as to approach the end face of the optical fiber ceramic ferrule, so that the end face of the optical fiber ceramic ferrule can be pre-treated. The device and method disclosed by the invention eliminate uncertain factors caused by manual operations and increase accuracy and efficiency of end face pre-treatment.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an end face pretreatment device and method of a small optical fiber ceramic ferrule. Background technique [0002] The ceramic ferrule is a small ceramic cylindrical tube fired from zirconia. It has a hard texture and is the most commonly used and the largest number of precision positioning parts in optical fiber communication networks. It is often used in the manufacture of optical fiber connectors and optical coupling of devices. The main function of the ceramic ferrule is to realize the physical connection of optical fibers. [0003] In order to ensure low loss when the ferrule transmits signals, it is necessary to grind the end face of the ferrule. PC (physical contact) grinding is one of them. The shape of the ferrule is small, and there are strict size requirements for the PC surface vertex offset and curvature radius , Grinding product quality requirements a...

Problems solved by technology

This grinding equipment and method has the following disadvantages: when the fiber optic ceramic ferrule is ground to a certain extent, it is necessary to manually press down the grinding tool to ensure that the fiber optic ceramic ferrule has a certain grinding pressure. However, such downward pressure is often difficult to control , resulting in uneven grinding of the end face of the fiber optic ceramic ferrule, making it difficult to meet the 3D requirements for the end face of the fiber optic ceramic ferrule
