TH6D Advanced

Optical seam tracking for electric arc and laser applications

The TH6D-Advanced is our latest development of optical seam tracking sensors for automated laser or arc welding processes. Based on the proven triangulation principle and the latest camera technology, the sensor actively guides the process along the joint or the component edge, thus enabling reliable compensation of component tolerances.

Function description

The triangulation sensor scans the seam shape along the joint without actually touching it and transmits information including gap dimensions, joint edge offset and positioning of the tool relative to the workpiece surface to the robot controller. Integrated extraneous light filtering ensures smooth operation even in the area close to the process. Efficient signal analysis ensures reliable detection, especially on reflective surfaces.

Areas of application

  • Automated production processes: welding, adhesives, etc.
  • Interfaces to all popular robot controllers
  • Universal analogue / digital machine interface available

Advantages

  • Even more precise seam tracking thanks to new camera technology
  • Compact design for flexible use and best accessibility of work piece
  • Easy handling and maintenance concept
  • Suitable for thin and thick sheet metal applications

Properties

  • Seam tracking for standard joint types (e.g. fillet or T-joint) for compensation for component tolerances
  • Applicable on all popular and also high reflective material surfaces
  • Immune to electromagnetic effects (EMI)
  • Optical filters used to minimize sensitivity to extraneous light
  • Splash guard with integrated safety glass cleaning
  • Splash-proof housing
  • Safety-glass quick-change drawer
  • Integrated air cooling for the sensor
  • Robust design
  • Interfaces for all well-established robot controls
  • Universal interface digital / analog

Features

  • integrated air flushing of protective glass
  • integrated cooling by air
  • working temperature +10°C up to +45°C
  • box splash water protected (IP64)
  • easy and rapid exchange of protective glass
