Machine Guidance

Machine vision makes for a great tool for machine guidance applications. Typically a camera is being used to analyze and control the operation of a tool with respect to a workpiece. In this example 2 cameras are used to control the positioning of a set of weld torches with respect to an axle assembly.  The axle is clamped up and the weld torches drop into position, typically aiming for the root of the weld joint.  At that point the cameras take a look at the alignment and re-position the torches to align to a specified offset from the root point.  Once in alignment the torches are allowed to ignite and complete the circumferential weld.   In other cases, a camera may be used to locate an object and then send feedback to a manipulator for pick up and/or processing or to guide a slitter on a hi-speed web line.
