Consumers spend some $1 billion to buy 2 billion lightbulbs each year in the U.S. That’s more than 6 million every day. High-speed automated assembly is the only way to meet that kind of volume.
Flexible feeders are great at helping manufacturers accommodate product variants on the assembly line. After the feeder presents parts to a vision-guided robot, one or more cameras take images of the parts, and vision software tells the robot which parts are pickable and which are not. The robot then retrieves the parts for kitting or assembly.
A&H Meyer, a manufacturer of cable management systems for furniture, approached RNA Automation Ltd. to design a flexible automation system to sort, separate and feed busbars. The company wanted a system that could handle 12 different lengths of flat and crimped busbars with minimal changeover time.
The manufacturer needed to present thin steel blades down an assembly line in a specific orientation. However, the parts were essentially symmetrical, with the exception of a small notch that had to be presented on the right side. With no real differences in the part other than this notch, feeding them to an assembly mechanism with 100 percent accuracy was a challenge.
