The TH6i is designed for optical seam tracking in automated welding processes using an arc or laser. The active seam recognition can detect the position of the workpiece and ensure that the tool is positioned accurately.
TH6i
Optical sensor for seam tracking on butt joint with 0-gap
Function description
The TH6i 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 technique
- Approved with high reflective surfaces as stainles steel or aluminum
- Three laser lines: thus excellent stability during the acquisition of measurement data
- Simple to operate
Properties
- Seam tracking for standard joint types, specially on butt joint with 0-gap to correct device tolerances
- Applicable on all popular and also high reflective material surfaces.
- Immune to electromagnetic effects (EMI)
