Abstract

The invention discloses online detection equipment forglass fiber yarn based on machine vision, which comprises an LED line light source erected above the glass fiber yarn, wherein an industrial camera is arranged on one side of the LED line light source, the LED line light source and the industrial camera are connected in parallel with an acquisition trigger control panel, the acquisition trigger control panel is also connected with a rotary encoder, the rotary encoder is located on a glass yarn production line, the industrial camera is connected with the input end of the industrial control computer, and the output end of the industrial control computer is connected with a defect alarm prompter. The invention further discloses a detection method of the online detection equipment for the glass fiber yarn based on machine vision, the machine vision technology is adopted, non-contact and non-damage detection of the glass fiber yarn is achieved, and the problem of non-hair detection in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of yarn detection, and relates to an online detection device for glass fiber yarn based on machine vision; [0002] The invention also relates to an online detection method for glass fiber yarns based on machine vision. Background technique [0003] Glass fiber (original name in English: Fibreglass) is an inorganic non-metallic material with excellent performance. Less abrasive. It is made of pyrophyllite, quartz sand, limestone, dolomite, boronite, and boronite as raw materials through high-temperature melting, wire drawing, winding, and weaving. The diameter of its single filament is several Micron to more than 20 microns, which is equivalent to 1 / 20-1 / 5 of a hair, and each bundle of fiber filaments is composed of hundreds or even thousands of single filaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and ...
