Coherix Robot Vision System for Adhesive Bead Inspection

Complete Inline Bead Inspection & Adaptive Control System for Dispensing Robots

Transform your automated adhesive dispensing process with an integrated hardware and software solution from Coherix that not only ensures precise bead application, but also actively monitors and corrects issues in real time. By combining advanced 3D sensor technology with adaptive process control software, this dispensing robot vision system allows manufacturers to achieve consistent quality while preventing costly errors, downtime, and production delays.

Coherix 3D Adaptive Process Control (APC)

Preventing + Adapting. Every Day. All Shifts. All the Time.

Coherix goes beyond basic adhesive bead inspection by actively controlling and correcting the dispensing process in real time. When there’s a gap in the material, the Coherix vision system can proactively fix it. When the volume of material drifts out of spec, it is instantly corrected. When part variation risks a nozzle crash, the robotic vision system dynamically adjusts to prevent it. Every aspect of the process is continuously optimized to exacting specifications at a microscopic level—resulting in zero defects, fewer line stoppages, reduced waste, and lower operating costs. This is not a future concept—this capability is available today.

Adaptive Process Control Solutions for Dispensing

• Coherix 3D AutoRepair™: Automatically repairs gaps, bubbles, neck downs, and low-volume defects with no human intervention
• Coherix 3D Z-Tracking™: Dynamically maintains optimal tip-to-part distance to prevent broken nozzles and scrap
• Coherix 3D Lateral Tracking™: Maintains precise bead-to-edge positioning to prevent squeeze-out and part rejection
• Coherix 3D VAC® (Volume Adaptive Control): Detects volume variation and automatically adjusts output to ensure consistent bead volume
• Coherix 3D LocationMaster™: Locates parts in 3D space and sends offsets to the robot to correct dispensing paths
• Coherix 3D NozzleCheck™: Detects material buildup on the nozzle to prevent defects and downtime
• Coherix 3D TCP Locator™: Measures actual nozzle position and automatically recalibrates the robot Tool Center Point (TCP) in real time

System Components

The Coherix robot vision system hardware features a compact 3D sensor ring with four high-speed lasers mounted around the dispensing nozzle, delivering complete 360° bead inspection coverage with no blind spots. Built for industrial environments, the IP67-rated enclosure ensures reliable performance in demanding production conditions.

The Coherix software platform provides real-time adhesive bead analysis, adaptive process control, and full production traceability—enabling manufacturers to monitor, optimize, and automatically correct dispensing performance as it happens.

Key Benefits

• Real-Time Quality Assurance: Monitor adhesive bead width, height, volume, and placement during dispensing—with instant detection and correction of defects
• Prevent Costly Errors: Identify and resolve issues before they lead to product failures, recalls, or scrap
• Increase Production Throughput: Maintain optimal adhesive dispensing speeds while ensuring consistent bead quality
• Reduce Material Waste: Minimize over-application, rework, and scrap through precise control
• Protect Equipment & Tooling: Prevent nozzle crashes and damage with real-time surface tracking and adaptive adjustment

Advanced Features

360° Bead Monitoring
