Embodiment Construction

[0014] As shown in Figure 1, the ceramic tile size and shape online visual measurement system of the present invention is installed on the tile production line, located at the rear of the edger, and the ceramic tiles 1 polished by the edger pass through the bottom of the measurement system on the conveyor belt in turn. subject to measurement. The online visual measurement system includes two transverse guide rails 5,11 parallel to each other. The transverse guide rails 5,11 are fixed on the frame (not shown in the accompanying drawings) of the entire measurement system and cannot be moved. There are slide rails respectively. Two parallel longitudinal guide rails 4, 7 are arranged perpendicularly to the transverse guide rails 5, 11, and the two ends of each longitudinal guide rail are erected on the transverse guide rails 5, 11 through a slide plate 13 respectively, and the slide plate 13 cooperates with the slide rails of the transverse guide rails , so that the longitudinal ...

Abstract

The invention discloses a size and shape online visual measurement system of ceramic tile; it was installed with two horizontal guide rails and two vertical guide rails fixed on the frame above the belt conveyer, the two vertical guide rails were installed with slide rails, slide rail on each vertical guide is set with two fore and after sliding block, each sliding block was installed with camera erecting fixture adjustable for height with a CCD camera fixed on it, four CCD camera were connected with computer image acquisition module, each CCD camera take a picture of angle of tile. The present invention overcomes the error of optical imaging, as well as the shortcomings of low measurement accuracy induced by the larger the tiles, the lower the measurement accuracy was, to achieve the measuring accuracy of 0.05 mm; as it simply only measure the size and shape, its detection speed was more faster, can less than 500 ms, can achieve real-time measurement in the ceramic tile production line.

Description

technical field [0001] The invention relates to a measurement system, in particular to an automatic visual measurement system for on-line (on-line) detection of various sizes and shapes of ceramic tiles. Background technique [0002] The size and shape errors of tiles have a great influence on the quality of tiles. Most manufacturers manually measure the size and shape of tiles, and there are many problems in the accuracy, stability and efficiency of measurement. Therefore, people are in urgent need of developing a high-efficiency, high-precision machine testing equipment, which plays an important role in the quality control of ceramic tile production. At present, someone has developed an online visual measurement system for ceramic tile production with a single CCD camera. Each edge of the tile displayed in the image is calculated by some measuring tools to calculate the size of the tile being measured. The system compares the value with the qualified value. If the value...
