Machine Vision Evolves
by Michelle Bangert
While cost has gone down, machine vision performance has gone up, so says Marcel Singleton, founder and director of business development, The Value Engineering Alliance (Cambridge, MA). "If it can be done by machine viion, it can be done faster and better," Singleton says. Vision has come a long way since 1984, when Singleton began working in Analog Devices' industrial automation division's machine vision product groups. A vision system went for $30,000 to $40,000, and typically companies made proprietary systems.

 Reintroducing Machine Vision
by David Dechow
Over the years, machine vision has become an important tool for quality analysis. As a technology, it is well-suited for on-line improvement of the manufacturing process. Yet machine vision is not as ubiquitous on the plant floor as might be imagined. According to some market experts, operators barely have scratched the surface with respect to opportunities for machine vision inspection in the manufacturing process. Perhaps it is time to reintroduce machine vision to the quality professional, discuss where the technology is today and review how machine vision can be used successfully.
Machine vision is an automated technology in which images are captured and transferred to a computer-image acquisition-and then processed to perform an inspection task and report the results-image analysis. Although sometimes implemented off-line, it is most effective when used as an integral part of a manufacturing process to capture production errors. Machine vision inspection can enhance quality when used to evaluate manufacturing at various steps in a process, thereby providing immediate and targeted feedback that often includes information about how to improve the process.
Overall, machine vision technology is continually changing, growing and improving. Processing power has increased significantly in just the past few years, and higher resolution imagers are more readily available. At the same time, component costs continue in many cases to decline, making machine vision a cost-effective technology for the plant floor. According to the Automated Imaging Association, the machine vision industry will experience significant growth through 2010, with some industry sectors posting double-digit annual percentage increases in the number of units sold.

 Vision Ensures Pen Quality
Although reliable, the machine occasionally creates defective pens as a result of improperly fed parts or tips that split during insertion. In the past, the company relied on operators to spot defects. But, because of high-production speeds, guaranteeing consistent product quality was difficult, if not impossible.
Faced with increased global competition and the high value of the New Zealand dollar, BIC realized it needed to solve this problem as part of an overall campaign to improve productivity and reduce its production costs. With this in mind, it installed a machine vision system that uses a pair of In-Sight 5100 vision sensors from Cognex Corp. (Natick, MA), one for tip inspection and one for end-plug inspection. The company also implemented special-purpose, LED-based lighting to increase imaging effectiveness and reliability.
"As a small plant we suffer from economies of scale compared to the larger plants offshore. We've looked at this technology before, but this time the price performance is at a level where we can justify the investment," says plant manufacturing manager Bernie Jamieson. "I've been impressed with what this equipment can do, how easy it's been to set up the inspections and how additional inspections can be added over time." Learn more... |
