Piston Inspection for the Automotive Industry

KEYENCE offers vision systems for automotive manufacturing that enable manufacturers to conduct accurate inspections on pistons and individual components. Our machine vision systems are designed to help automotive manufacturers make piston inspections for defects and anomalies that can cause problems such as poor combustion, excess carbon buildup, and high emissions.

Vision Systems for Piston Defect Inspection

Our vision systems help manufacturers check for many piston defects, including swarf in piston grooves. To verify pistons' design alignment to quality standards, KEYENCE provides manufacturers with inspection systems that identify issues such as long scratches affecting cylinder compression levels and piston performance while still tolerating normal variations and allowable anomalies on compression ring surfaces.

VS Series

Our AI vision systems use both rule-based and AI inspection tools on the same target to make quick and accurate piston visual inspection. Vision systems also give real-time data visualization for operators to monitor their inspections.

CV-X Series

Our CV-X Series intuitive vision system is an innovative and user-friendly vision system that utilizes high-speed cameras, amongst other technologies, to check for defects and irregularities on pistons.

2D VGR Series

The 2D VGR Series is a 2D Vision-Guided Robotics inspection system that connects to all major robot manufacturers for picking and placing parts during piston inspection tasks.

Challenges in Piston Visual Inspection

Defect Recognition

An inspection system may struggle to classify defects from white areas, rust spots, and even surface fissures, which are all inspection permissible. Our vision systems can detect allowable variations from true defects.

Geometry Inspections

Inspecting for roundness, straightness, and other geometric features of a piston can be complex. Our VS Series vision product uses AI algorithms and rule-based inspection tools to capture and analyze every geometry feature.

High-Volume Production

The need for quick inspection on multiple pistons can be demanding on traditional inspection methods and systems. Use our vision solutions to conduct rapid piston defect inspection even in challenging conditions.

Appearance and Lighting Conditions

Due to the reflective metallic surface of pistons, defects on compression rings can be difficult to detect. KEYENCE vision products use advanced algorithms and controlled lighting to handle blurriness and achieve focused imaging.
