Laser Marking and Image-based Industrial ID Reader Save Hundreds of Thousands of Dollars


An electronics manufacturer produces thousands of different part numbers of high value electronic products intermixed on the same assembly line. The large number of different products built on the line, coupled with the fact that many of the parts that distinguish these products are so similar, made it difficult for assemblers to verify that they were assembling the products correctly.

The difficulty in identifying parts, combined with the fast pace of the assembly line, resulted in a large amount of assemblies that required rework or had to be scrapped. The electronics manufacturer previously experienced several hundred thousand dollars a year in losses when incorrect parts were added to, and/or the wrong operations were performed, on assemblies. An additional issue was the inability to easily track the WIP inventory which resulted in large amounts of money tied up in raw materials in process.

After reading the alphanumeric characters, the finishing and inspection steps take place, including balancing and sound testing. Finally, the robot creates stacks of six discs each in a stainless steel box and then placed a wood cover on top. The robot's In-Sight camera locates the exact position thanks to a simple black cross.
