Abstract: According to the surface quality inspection requirements of honeycomb ceramics, an intelligent image inspection and sorting system based on machine vision was designed. The working flow of the designed system includes four steps: top inspection, bottom inspection, side inspection and sorting. Top images and bottom images are captured with area scan CCD cameras. The workpiece rotation (360°) was driven by the turntable unit driven by a servo motor and an encoder while workpiece side images were captured with line scan CCD cameras. The captured images were sent to IPC inspection software for processing and judgment. Then the judgment results were sent to the PLC electrical control system. Unqualified products were picked out by the PLC-controlled sorting unit. The designed system realized the rapid surface inspection and accurate sorting of honeycomb ceramics and improved the production efficiency.

Abstract: Honeycomb ceramics is the key component of the thermal flow-reversal reactor, which is for oxidation of coal mine ventilation air methane. In this paper, numerical simulation method was used to study the honeycomb ceramics' heat transfer process, and the effects of temperature difference and hole side length on heat transfer and the resistance losses were investigated. The calculating results show that the temperature difference between the gas and honeycomb ceramics is larger, then the heat transfer effect is better, and the resistance loss is bigger. In the situation other parameters are the same, then the hole side length is longer, the heat transfer efficiency is lower, and the resistance loss is smaller.
