Wiredrawing automatic ending control system based on programmable logic controller and control method thereof

Abstract

A wiredrawing automatic ending control system based on a programmable logic controller and a control method thereof according to the invention relate to a wiredrawing automatic ending control system based on a programmable logic controller (PLC) and a man-machine interface and a control method thereof. The wiredrawing automatic ending control system is used for automatically judging defects of optical fiber during an optical fiber manufacturing process and performing automatic ending control. The wiredrawing automatic ending control system comprises an on-line optical fiber defect detecting device, automatic optical fiber cutting and coating receiving devices, a polarization film dispersion twisting automatic flicking device, a PLC and a host computer, wherein the on-line optical fiber defect detecting device comprises an optical fiber measuring probe and a signal processor; two sets of automatic optical fiber cutting and coating receiving devices are arranged and are respectively a primary automatic optical fiber cutting and coating receiving device and a secondary automatic optical fiber cutting and coating receiving device; the polarization film dispersion twisting automatic flicking device is mounted on the lower part of a secondary coating curing furnace; and the polarization film dispersion twisting automatic flicking device comprises a twisting guide wheel, a twisting motor, an automatic flicking cylinder and a horizontal holder.

Description

technical field [0001] The invention relates to a programmable controller-based automatic wire drawing end control system and its control method, which relates to an automatic wire drawing end control system and its control method based on a programmable logic controller (PLC) and a man-machine interface, and is an optical fiber manufacturing process A system that automatically judges fiber defects and performs automatic end control. Background technique [0002] In the process of optical fiber production, there are usually quality problems in the optical fiber. The coating defects are observed under the electron microscope after the optical fiber take-up machine is finished, and then manual intervention is carried out to deal with it. There is a certain lag, and resulting in defective products. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the existing production operation process, and to provide a...
