A vision system utilizes machine vision in an assembly line to examine products for quality. Machine vision uses imaging technology to sense, sort and guide without making contact. Vision inspection systems can be used to search for surface defects, count products as the come down the line, sort for contaminants and to scan serial numbers. This automated process can essentially save on the cost man-hours while not sacrificing the quality of the products.
A vision system is capable of magnifying their vision multiple times and may catch imperfections and flaws indiscernible to the human eye. A vision system can inspect at a much higher rate than human eyes and are more precise and consistent than the human workforce they often replace. Vision systems come in a variety of different types including optical inspection systems, optical sorting systems, vision sensors, CCD cameras, laser inspection, magnetic imaging, robotic vision and much more.
A vision system is an inexpensive replacement for manpower and can be run constantly, twenty-four hours a day, seven days a week. Infrared light can also be utilized to view the interiors of products to check for quality.
A vision system can rely on digital cameras and pattern recognition software to “see.” Although machine vision technology has improved significantly in the last few years, computers are still incapable of adapting quickly to new tasks in the way that human eyes do. For this reason, a vision system is usually programmed to fulfill those assignments that require consistent repetition of the same task.
