Video-assisted glue dispensing method for LC optical fiber connector

Abstract

The invention discloses a video-assisted glue dispensing method for an LC optical fiber connector. The video-assisted glue dispensing method comprises the following steps: a glue dispenser, comprisinga glue dispensing tube, a camera, a connector fixing clamp, a glue dispenser base, a control computer and a communication cable, is provided; a flexible needle on which a guider is mounted is provided, and the flexible needle is mounted on the glue dispensing tube; the LC optical fiber connector is provided and mounted on the glue dispensing base; the tail part of the LC optical fiber connector is shot by the camera, and shot images comprise an image of the tail part of a metal support tube and an image of a tail sleeve; the image of the tail part of the metal support tube and the image of the tail sleeve are analyzed by an image processing program to seek out the center of the metal support tube and the center of the tail sleeve; a point, close to the center of the metal support tube, ona connecting line of the center of the metal support tube and the center of the tail sleeve is determined as a glue dispensing location; the glue dispensing tube on the glue dispenser is controlled and the flexible needle is driven to be aligned with the glue dispensing location through the control system; the control system drives the glue dispensing tube and enables the flexible needle to stretch into the tail sleeve of the LC optical fiber connector; the flexible needle reaches a mortice tail handle and then stops moving; and the control system drives a piston to move and pushes glue to beinjected into the tail handle. The tail part of the LC optical fiber connector is shot by video recognition, the center of the tail sleeve and the center of the metal support tube are analyzed by theimage processing program, and the glue dispensing location is determined. Since the glue dispensing location is within a region of not only the tail sleeve but also the mortice tail handle, the flexible needle can be successfully inserted into the mortice tail handle.

Description

technical field [0001] The invention relates to the optical fiber communication industry, in particular to a dispensing method for video-assisted LC optical fiber connectors. Background technique [0002] Optical fiber communication is a communication method that modulates signals such as images and data to be transmitted onto an optical carrier, and uses optical fiber as a transmission medium. The frequency of light waves as a carrier is much higher than that of radio waves, and the loss of optical fibers as a transmission medium is much lower than that of coaxial cables or waveguides. Therefore, compared with cable communication or microwave communication, optical fiber communication has many unique advantages. [0003] Optical fiber connector is a device for detachable connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving ...

Problems solved by technology

[0006] At present, due to the plastic structure of the LC-type optical connector boot, there is a certain natural curvature, so the tail contour circle of the dispensing needle inserted into the boot can not be concentric with the tail handle contour circle, and there are a large number of product branches. There is a big deviation
