Device for on-line detection and classification of fiber tripping defects of chemical fiber spindles and detection and classification method thereof

Abstract

The invention discloses a device for on-line detection and classification of fiber tripping defects of chemical fiber spindles. The device comprises a spindle conveying device, an image acquisition device and a defect elimination module which are positioned on the spindle conveying device, and a good product waiting area and a bad product waiting area which are connected with the spindle conveyingdevice; the defect elimination module comprises an image processing and decision module, a quality statistical evaluation module and a defect control module; the image acquisition device comprises closed dark boxes, LED light source groups, CCD camera groups, image acquisition cards, digital signal processors and memories; the closed dark boxes are arranged above and below the silk ingot conveying device; and the LED light source groups, the CCD camera groups, the image acquisition cards, the digital signal processors and the memories are arranged in the closed dark boxes. The device has thefollowing beneficial effects that collected silk ingot images are processed by combining machine vision and an image processing technology, the interference number and morphological characteristics ofthe tripping fibers and interference fibers can be simultaneously detected, the fiber ingots with the fiber tripping defects can be detected by using detected fiber tripping information, and a sourcecan be traced by using statistical interference information.

Description

technical field [0001] The invention relates to the technical field of on-line detection of trip wire defects, in particular to an online detection of trip wire defects in chemical fiber ingots that can detect trip wires and interference wires at the same time, and can statistically detect the number of interference and morphological characteristics of trip wires and interference wires And grading device and detection grading method thereof. Background technique [0002] Trip wire (also known as spider web wire) is a wire that appears on the end of the winding bobbin, part of the wire deviates from the normal winding trajectory, changes from an arc to a string, and the length of the string exceeds 5cm. The occurrence of trip wires is closely related to machine process adjustment, production management and mechanical conditions. Trip wires can be reduced by standardizing production management and improving mechanical conditions. The existence of trip wires seriously affects ...
