TH6D

Optical seam tracking for electric arc and laser applications

The TH6D is designed for optical seam tracking in automated welding processes using an arc or laser. The sensor also supports the application of adhesives and other tracking processes. The active seam tracking detects the position of the joint/component edge and ensures precise positioning of the tool.

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

  • High reliability by use of state-of-the-art camera technology
  • Works with reflective surfaces such as stainless steel or aluminium
  • Three laser lines to ensure excellent measurement stability
  • Simple to operate

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

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
