Laser Profiling & Tracking Systems OTC DAIHEN® Sensor Range

Sensor Models & Features

1. FD-QD Quick Detect

High-accuracy part finding: Utilizes advanced laser triangulation to detect workpiece positions with an exceptional precision of ±1 mm on thin to medium gauge plates.
Fast operation: Delivers scanning and search speeds up to 200 cm/min, offering significantly faster part setup times compared to legacy mechanical touch sensors.
Seam & groove profiling: Capable of identifying multiple joint configurations and instantly visualizing real-time profiling results directly on the teach pendant display.

2. FD-QTS Laser Tracking

Look-ahead seam tracking: Projects a dense laser stripe combined with vision tracking cameras to evaluate the seam path profile ahead of the arc, enabling dynamic, real-time path adjustments.
Ultra-high tracking speed: Operates seamlessly at extreme processing speeds up to 1000 cm/min, making it ideal for high-speed automated production and laser-hybrid installations.
Integrated automation: Fully configured and controlled via the standard teach pendant software interface, completely removing the requirement for an external standalone PC.

Integration & Advantages

Seamlessly integrated into the OTC DAIHEN robotic welding cell architecture via native robot controllers and the intuitive teach pendant system.

• Maximizes welding consistency through automated real-time workpiece alignment cycles.
• Optimizes cycle times by reducing part localization and search durations.
• Provides broad application flexibility across varying plate thicknesses and diverse joint designs.
• Ensures low-maintenance operation without demanding physical modifications to the welding torch assembly.

Typical Applications

• Automated seam finding and structural joint profiling executed prior to welding arc initiation.
• Adaptive compensation routines to instantly counteract part misalignment or variance within manufacturing fixtures.
• High-speed processing lines utilizing automated MIG, TIG, plasma, and precision laser systems.

System Architecture Note: Both hardware systems utilize digital synchronization with the main control processor to maintain tracking metrics across complex multi-axis geometric trajectories.
