China has become a major producer and exporter of pen products in the world.One of the key technologies in pen making industry is pen tube testing.Aiming at the requirement of automatic inspection,a pen tube defect automation inspection system was designed to improve the pen tube defect detection efficiency and production quality of pen tube manufacturing enterprises.Based on the machine vision and the gravity center classification device,the defect forms and types of pen tubes were identified and counted by modular detection system to achieve high-efficiency and high-precision pen tube defect detection,defect elimination and automatic sorting.Using the automatic defect detection algorithm and computer vision detection technology,the defect edge detection was carried out,the defect area of pen tube was segmented,the main defect types were defined,and the pen tube defects were judged and classified.By constructing and training convolution neural network,a convolution neural network model with high fitting degree was obtained to analyze the defect of pen tube.The experimental results show that the pen tube defect automation detection system can objectively evaluate the defects of pen tube,raise the production efficiency of pen tube,improve the quality of finished products of the production line,which has higher engineering application value.
