Abstract

The invention discloses an optical cable surface defect detecting system based on planar array CMOS cameras. The optical cable surface defect detecting system comprises the one or more planar array CMOS cameras, an industrial personal computer, an analysis detection module, an alarming module and a storage module. A to-be-detected optical cable on a production line is continuously shot through the high-speed planar array CMOS industrial cameras, stripping, swelling, bubbles and the like, caused by impurities of materials or improper technological control in production, of the surface of a jacket of the product can be rapidly detected in real time, production efficiency and product quality are effectively improved, and manufacturing cost and the rejection ratio are reduced. Compared with the prior art, the optical cable surface defect detecting system has the advantages that optical cables which are made of most materials and are of most structures can be detected, the detecting speed and detecting efficiency are higher, cost is lower, and the optical cable surface defect detecting system is quite suitable for online detection on the high-speed production line.

Description

technical field [0001] The invention relates to the technical field of communication optical cable detection, in particular to an optical cable surface defect detection system based on an area array CMOS camera. Background technique [0002] In recent years, with the deepening implementation of the "Broadband China" strategy and the vigorous deployment of 4G networks, my country's optical fiber and cable industry market has entered a period of vigorous development. The construction of broadband network, especially the construction of FTTx network, has become the main driving force to stimulate the domestic demand for optical fiber and cable. However, limited by the network construction model, there are still some problems in the popularization of fiber-to-the-home, such as the relative lack of pipeline resources in cities and the difficulty of terminal access. In order to overcome these bottlenecks, new special optical cables, represented by air-blown micro-cables, which ca...

Problems solved by technology

However, it has high requirements on the lighting source system, and due to the progressive scanning motion of the line array camera and the existence of the corresponding position feedback link, the complexity and cost of the system are increased, resulting in a long time for image acquisition, which is difficult to achieve in the high-speed optical cable production line. real-time synchronous detection

In addition, since this detection system uses a CCD industrial camera, although the camera has high pixel accuracy, its performance is already excessive for the detection of optical cable surface defects using a line array camera, which will only make the system expensive and cause detection costs. waste of
