Ceramic wall and floor tile flatness detection device and method

Abstract

The invention relates to a ceramic wall and floor tile flatness detection device and method, and the device includes an illumination module and an acquisition module. The illumination module includesa grid-shaped dense laser mounted above a detection area; and the acquisition module includes a camera mounted above the detection area. The ceramic wall and floor tile flatness detection device usesgrid-shaped dense laser to irradiate the surface of a ceramic tile in a direction perpendicular to the surface of the ceramic tile, thereby obtaining a ceramic wall and floor tile with evenly distributed surface grids; utilizes the acquisition module, acquires image data of the ceramic wall and floor tile through a CCD camera, and sends the image data to a positioning module; based on the positioning module, locates a deformation area of the image data and sends to a calculation module, adopts a BP neural network to process the deformation area, and calculates the flatness of the surface of the ceramic wall and floor tile where deformation occurs; and finally, utilizes a grading module, and adopts a quality fuzzy expert system to realize quality grading of the ceramic wall and floor tile,so as to solve the problem of low detection accuracy of surface flatness of the ceramic wall and floor tile.

Description

technical field [0001] The invention relates to the technical field of quality detection of ceramic wall and floor tiles, in particular to a device and method for detecting the flatness of ceramic wall and floor tiles. Background technique [0002] The surface flatness of ceramic wall and floor tiles is one of the main factors affecting its quality, so the flatness detection of ceramic wall and floor tiles is particularly important. [0003] Due to the limitation of technical level, most ceramic enterprises in my country are still in the manual detection stage for the measurement of flatness, so the detection accuracy is difficult to be guaranteed. Although some relatively mature equipment for testing the flatness of ceramic wall and floor tiles have been developed abroad, these equipment often appear "acclimatized" in China. In addition, the high price of these devices also restricts their widespread use in China. Contents of the invention [0004] The purpose of the pr...
