When a Tier 1 supplier of automotive exhaust system components turned toward automation for quality inspection, it reached out to Neff Group Distributors (Indianapolis, IN, USA; https:/effautomation.com) to develop a machine vision system that verifies not only the integrity of a specific part, but also its proper assembly prior to shipment. Previously, the supplier did not have a process in place to detect defects on butterfly valves, and as a result, an end customer reported that the parts were flawed upon delivery. At one end of the butterfly valve is the point where the closure plate, or vane, pivots. That pivot point is critical to the function of the valve. A misshapen, broken, or otherwise damaged pivot can hinder the butterfly valve's operation.
