Design of Automatic Detection System of Ceramic Tile Flatness

In order to achieve automatic detection of the tile flatness and automatic classification of product quality, the top control unit is touch screen, which can download parameters, display result information, control and debug device. Lower machine works as follows, when the tile is transferred to the test platform in the correct position, the laser displacement sensor collects 25 characteristic points information from moving the tile surface, via the A / D module,the information is converted into digital signals, according to specific flatness algorithm, PLC calculates flatness and achieves tile classification. Practice shows that the accuracy of tile flatness is 0.1mm, detection efficiency is 40 pieces per-minute. The system is suitable the quality control of ceramic tile product.
