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 in real time.
TH6D
Optical seam tracking for electric arc and laser applications
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, soldering, adhesives etc.
- Interfaces to all popular robot controllers
- Universal analogue / digital machine interface available
- High electromagnetic compatibility thanks to nickel-plated coating
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
- High electromagnetic compatibility thanks to nickel-plated coating
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
- Integrated air cooling for the sensor
