Coherix 3D GlassMaster Tracker™ Inline Urethane Inspection System

High-Profile Bead Inspection & Adaptive Process Control for Urethane Dispensing The Coherix 3D GlassMaster Tracker™ delivers inline 3D inspection and real-time adaptive process control for high-profile urethane bead dispensing. Designed for automotive glass bonding and battery sealing applications, the high-profile bead inspection system verifies bead profile, position, and edge location while actively controlling the dispensing process to maintain consistent, high-quality seals. By combining high-speed 3D sensing with closed-loop robot control, the GlassMaster Tracker urethane bead inspection system reduces process variation, minimizes manual intervention, and helps prevent leaks, rework, and scrap—without slowing production. From Inspection to Automatic Process Control GlassMaster Tracker goes beyond basic urethane bead inspection by continuously monitoring bead position, edge location, and tip-to-surface distance, then sending real-time corrections to the robot. Maintains precise bead-to-edge placement for proper sealing Controls tip-to-surface distance within tight tolerances (±1 mm) Compensates for part variation and robot path deviation Adapts automatically to changing production conditions This transforms urethane dispensing from a reactive process into a controlled, stable, and repeatable operation. Adaptive Process Control (APC) Solutions Adaptive Process Control is enabled through configurable software modules: Coherix 3D LocationMaster™: Locates parts in 3D space and sends offsets to adjust the robot dispensing path Coherix 3D Z-Tracking™: Maintains precise tip-to-part distance to prevent nozzle contact and ensure proper bead formation Coherix 3D Lateral Tracking™: Controls bead position relative to edges and features to prevent squeeze-out and seal defects Coherix 3D VAC® (Volume Adaptive Control): Detects volume variation and automatically adjusts material output to maintain consistent bead volume Advanced 3D Inspection System Combining compact sensor hardware with real-time processing software, the GlassMaster Tracker urethane adhesive bead inspection system delivers full inline visibility and control. Four high-speed laser sensors capture the complete urethane bead profile with 360° coverage and no blind spots Processes up to 400 samples per second per sensor for real-time feedback Tracks bead position relative to glass edges—critical for seal integrity Detects variation caused by upstream manual processes, such as rubber dam placement Key Benefits of Inline Bead Inspection & Control Improved Seal Quality: Maintains consistent bead placement, profile, and volume Reduced Scrap & Rework: Identifies and corrects variation before defects occur Increased Process Stability: Compensates for part and robot variation automatically Minimized Downtime: Reduces the need for manual adjustments and robot reprogramming Full Traceability: Captures inspection data for quality and compliance High-Speed Operation: Maintains throughput without slowing production Built for Production Environments Designed for demanding manufacturing conditions, the GlassMaster Tracker urethane bead inspection system delivers reliable performance on the line: IP67-rated sealed housing for protection against dust, fluids, and harsh environments Shock-resistant, solid aluminum construction for durability in robotic applications No moving parts for long-term reliability and minimal maintenance Mounts directly around the dispensing nozzle (robot-mounted or pedestal) Integrates with existing robots and dispensing systems without complex programming Proven 3D Technology Platform The GlassMaster Tracker is built on Coherix’s proven 3D imaging platform: Deployed in hundreds of systems worldwide Inspecting millions of parts across global manufacturing lines Typical Applications Automotive glass bonding (windshield, backlite, fixed glass) Battery cover sealing and enclosure protection Structural adhesive and sealant dispensing in automotive assembly Get Expert Support Whether you’re optimizing an existing dispensing process or implementing inline inspection for the first time, Coherix can help configure the right solution for your application.
