Automatic inspection system refers to the use of various inspection instruments to measure, indicate or record the main process parameters of the production process system. In the Fourth Industrial Revolution (Industry 4.0) era, competition among enterprises has become increasingly fierce. Most enterprises use automated testing to replace traditional manual testing to improve production efficiency and product quality. This paper investigates the current inspection process in the manufacturing industry. It proposes and designs an automated inspection system for sandwich filling coverage and thickness for sandwich production to replace the original manual inspection. After simulation and comparison of the improved production line, it was finally verified that the modified production line could improve the yield and quality of sandwiches and can help manufacturers save human resources.
