Design of Automatic System to Detect the Difference in Outer Mouth Diameter of Daily Ceramics

The outer mouth difference in diameter is an important index to measure the quality of daily ceramics. Aiming at the quality inspection of daily-use ceramics with round mouth, an automatic system was designed to detect the outer mouth diameter. Different from the traditional outer diameter positioning detection of bearing parts, a non-positioning detection method was proposed in this work. By building an automatic detection device under embedded system, the outer mouth diameter is detected with a displacement sensor under visual guidance. The experimental results indicated that the non-positioning automatic device exhibited a promising effect, with rapid detection. The measurement accuracy is 0.1 mm and the time for measuring a piece of daily ceramic is 20 s, thus ensuring the accuracy and the quality inspection efficiency.
