Streamlining Bumper Inspection: A Case Study in Robotic Vision

A major automotive manufacturer faced the intricate challenge of inspecting 37 distinct variants of their SUV model, each with unique front and rear bumpers. With a complex child part assembly featuring 140 inspection points, the company needed a solution to automate variant classification and child part inspection. Their innovative response was a robotic vision system, in partnership with ABB robots. This system seamlessly integrated machine vision, enabling continuous, on-the-go inspections without production line interruptions. To tackle parts with the same color as the background, a structured pattern projector and machine learning pattern recognition algorithm were deployed, drastically reducing inspection time from 8 minutes to just 52 seconds. The system’s adaptability, allowing for remote updates to accommodate new models, solidified its role in enhancing manufacturing efficiency and quality control in the automotive industry.
