Online cable surface defect detection device and online cable surface defect detection method

Abstract

The invention relates to an online device and an online method for detecting surface defects of cables and optical cables particularly. The online detection device comprises a fixed support, a camera with a shooting angle covering the periphery of the outer surface of a detected cable is arranged on the fixed support, light sources or a light source are / is arranged in the side direction of and / or above the camera, and the control and output end of the camera is connected with a computer. When running through a shooting region, the detected cable is subjected to continuous shooting in sections, the shooting rate is 20-200 pictures per second, a cable running length and time recorder is also configured, and pictures are analyzed by a picture analysis program so as to judge the type of the surface defect of the cable. The online device can automatically and efficiently detect the surface defects of the cables so as to provide basis for further analysis, treatment and repair of the surface defects of the cables, is simple in structure and reasonable in arrangement, can be directly installed on complete cable production equipment to be in linkage with an equipment control system, is convenient to operate, and can efficiently detect the surface quality of the cables subjected to continuous production.

Description

technical field [0001] The invention relates to an online detection device and method for surface defects of cables, especially irregular optical cables. Background technique [0002] Most existing cables have smooth surfaces, and their cross-sections are mainly regular circles or rectangles. For this simple cross-sectional shape of the cable, the existing cable surface defect detection methods mainly include size detection and color difference detection. [0003] The small-diameter micro-air-blown optical cable has some irregular spiral structures on the surface, and there are sleeves of various colors inside the optical cable. It is difficult for existing detection devices to detect irregular cable surface defects and damage. When the inner sleeve of the optical cable When the color of the cable is consistent with the color of the surface of the cable, the cable color difference detection cannot effectively find the surface defects of the cable. As a result, the surface ...

[0003] The small-diameter micro-air-blown optical cable has some irregular spiral structures on the surface, and there are sleeves of various colors inside the optical cable. It is difficult for existing detection devices to detect irregular cable surface defects and damage. When the inner sleeve of the optical cable When the color of the cable is consistent with the color of the surface of the cable, the cable color difference detection cannot effectively find the surface defects of the cable

As a result, the surface defects of the optical cable cannot be detected online, causing hidden dangers in the quality of the product

In severe cases, it will affect the air blowing laying of optical cables
