Real-time fiber winding defect visual inspection device based on double CDDs

Abstract

The present invention discloses a real-time fiber winding defect visual inspection device based on double CDDs. The device comprises a visual detection unit which comprises a global CCD camera which has a fixed position and is used for collecting a whole fiber winding image and a local CCD camera which has an adjustable position and is used for collecting a fiber winding local image. Both the global CCD camera and the local CCD camera are connected to an industrial computer. The industrial computer is connected to the local CCD camera through an electrical transmission unit and is connected to a display screen. According to the device, the double-CCD camera automatic online detection technology is used, the working position of the local CCD camera is adjusted through tracking fiber winding wire diameter change by the global CCD camera, thus the local CCD camera carries out online monitoring on a fiber winding in real time, the improvement of the fiber winding quality and defect detection efficiency is facilitated, the production cost is reduced, at the same time, the improvement of the degree of automation of fiber winding defect detection is facilitated, in an online real-time detection process, the fiber winding defect image information is recorded, and the problem backtracking is helped.

Description

technical field [0001] The invention belongs to the field of industrial visual computing, in particular to a dual-CCD-based real-time optical fiber winding defect visual detection device. Background technique [0002] Since it takes a long time to complete the winding of a round of optical fiber, and the winding parts are large in size and have many layers, the optical fiber winding needs to move left and right within a certain range during the winding process, so it is easy for the optical fiber to climb, extrude, sink, slide, and brush. Defects such as hair residue. At present, the quality of optical fiber winding is mainly inspected by human eyes, which is prone to "missed inspection". [0003] For the detection of optical fiber winding defects, the Chinese patent application number 201210189025.1 discloses a real-time optical fiber winding defect detection method based on machine vision technology, which uses machine vision technology to detect defects in ordinary optic...

Problems solved by technology

[0002] Since it takes a long time to complete the winding of a round of optical fiber, and the winding parts are large in size and have many layers, the optical fiber winding needs to move left and right within a certain range during the winding process, so it is easy for the optical fiber to climb, extrude, sink, slide, and brush. Defects such as hair residue

At present, the quality of optical fiber winding is mainly inspected by human eyes, which is prone to "missing detection"

[0003] For the detection of optical fiber winding defects, the Chinese patent application number 201210189025.1 discloses a real-time optical fiber winding defect detection method based on machine vision technology, which uses machine vision technology to detect defects in ordinary optical fiber rings according to the sampling detection method. Suitable for objects with small size, slow winding speed and low precision

The Chinese patent with the application number 201210477554.1 discloses an online monitoring and alarm system and method for optical fiber wrapping. It irradiates the light source along the tangent direction of the optical fiber ring, generates shadows through the imaging system, and judges the optical fiber according to the shadow of the optical fiber ring. defects, this method can only detect whether the optical fiber ring has defects of stacked fibers and leaked fibers
