Abstract
This paper presents the design and development of an automatic monomer filling system using machine vision in optics manufacturing. Currently, the production process is carried out by a trained worker. The monomer filling process, needs to be operated by hand and human vision is employed to control each step. The important procedure is to start-stop a valve to prevent liquid monomer overflow from glass molds. The proposed system consists of a Cartesian robot and a vision system. The vision system uses two cameras to capture four regions of interest (ROI) of four glass molds at the same time. The frame differencing technique is used to detect the difference between the last and the current video frames. The results show that each camera can be operated at real-time image processing at 52 frames per second, and the system can stop the valve for the filling monomer of each glass mold at the full level. As the result, productivity increased by 60% compared with the existing manual process making it possible to replace skilled workers. ฉ 2019 IEEE.
