Optical fiber cutter sliding block using elastic blade support

Abstract

The invention provides an optical fiber cutter sliding block using an elastic blade support. The optical fiber cutter sliding block comprises the elastic blade support, a blade, a blade support shaft, a blade support bearing, a blade support magnet, a sliding block body, a linear guide rail, a blade support limiting stopper and the like. According to the optical fiber cutter sliding block, a rigid cutting mode based on the relative initial positions of the blade and the optical fiber is changed into a flexible cutting mode based on the contact pressure of the blade and the optical fiber and capable of adjusting the pressure, so that the cutting quality and stability of the optical fiber are improved, and meanwhile, the requirements of the optical fiber cutter on material processing are reduced.

Description

technical field [0001] The invention relates to the field of optical fiber cutters for engineering, in particular to an optical fiber cutter assembly which scratches the outer circular surface of an optical fiber and then squeezes or knocks off the optical fiber along the scratched incision to form an optical fiber end face meeting engineering standards. [0002] technical background [0003] Optical fibers have been widely used in communication, medical treatment, sensors, navigation, and other fields. The main material for making optical fibers is high-purity quartz, so special methods need to be used for the connection between optical fibers. At present, two methods are mainly used in the engineering field: one It is a physical connection, which is to accurately align and fix the optical fibers to be connected, which is called cold splicing; the other is to further heat a group of precisely aligned optical fibers at high temperature to reach the melting point of the optical...

AI Technical Summary

Problems solved by technology

[0004] 1. The quality of optical fiber scratches is not uniform, and the deep cutting position and the shallow cutting position are not uniform due to uneven force, resulting in inconsistent cuts

[0005] 2. Due to the small diameter of the optical fiber, which is 0.125 mm, in order to achieve precise clamping of the optical fiber and ensure the accuracy of the relative position between the outer circle of the optical fiber and the edge of the cutting blade, it is necessary to use materials with higher hardness for the clamping structure and supporting structure , and high processing accuracy; currently on the market, most stainless steel presser feet and aviation aluminum materials are used as the clamping body, and most of the processing methods are precision CNC machining, which leads to relatively high material and processing costs.

[0006] 3. The relative position of the optical fiber and the cutting edge of the blade is adjusted before cutting, that is, the height of the blade is adjusted; due to the small scratch depth between the cutting edge of the blade and the optical fiber, affected by operating factors and environmental factors, the position of the optical fiber is also adjusted every time it is placed. There will be a small change, which will affect the relative position of the blade edge and the fiber and affect the cutting quality

[0007] 4. The rigid contact between the blade and the optical fiber during the cutting process leads to uneven force on the blade edge during the cutting process, which accelerates the wear of the blade and shortens the service life of the blade
