A Detection Device for Quality Assessment of High-Speed Moving Filter Rods Based on Machine Vision

This study builds an online detection device for quality assessment of high-speed moving filter rods based on machine vision. This detection device effectively addresses the problem of high defect rate associated with filter rods high-speed forming machines. Three basic components make up the device: a high-speed imaging system, a control and detecting system, and an electromechanical support system. The high-speed imaging system takes pictures of filter rods using a high-speed line array camera. Once the image is framed, the data is transferred to the industrial computer's image acquisition card via the camera link. When the industrial computer obtains the image data, it processes the images with machine vision methods and outputs the processing results to the PLC controller, which generates instructions for discarding defective filter rods based on the output detection results. The results indicate that the high-speed online detection device for filter rod quality based on machine vision effectively resolves quality issues such as excess capsules, missing capsules, mixed capsules, and capsules position shift during the high-speed production of filter rods.
