Problems solved by technology

[0002] Visual inspection has been successfully applied to the detection of defects such as color difference and outline of ceramic tiles. However, in the process of producing and processing tile patterns, pattern defects such as pattern outline deformation, loss, and color material flow are prone to occur. If manual inspection is relied on, it is easy to cause fatigue, Low efficiency and high missed detection rate, therefore, it is necessary to develop a new type of tile pattern defect detection system based on machine vision

Abstract

The invention relates to a tile pattern defect detection system based on machine vision, which includes a tile transmission module, a centering module and a vision detection module. The tile transmission module is composed of two parallel conveyor belts. The centering module is composed of the front spring sheet and contact switch, two sets of low-speed motors and motor drivers, eccentric wheels and push rods; the visual inspection module is composed of the rear spring sheet and contact switch, Composed of CCD camera, LED coaxial light source and image processing system. The system first centers the tiles to be detected, then takes pictures, and then matches the captured images with the standard image templates stored in the system to determine whether the tiles have pattern defects. The invention has the characteristics of high degree of automation, good reliability and flexible use, and can accurately detect pattern defects of ceramic tiles.

Description

technical field [0001] The invention relates to the technical field of tile detection, in particular to a machine vision-based tile pattern defect detection system. Background technique [0002] Visual inspection has been successfully applied to the detection of defects such as color difference and outline of ceramic tiles. However, in the process of producing and processing tile patterns, pattern defects such as pattern outline deformation, loss, and color material flow are prone to occur. If manual inspection is relied on, it is easy to cause fatigue, The efficiency is low and the missed detection rate is high. Therefore, it is necessary to develop a new type of machine vision-based tile pattern defect detection system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for detecting tile pattern defects based on machine vision. This device first centers the tiles to be detected, then takes pictures, and ...
