Touch sensor QR-SN-TS-W

Product overview:
The tactile sensor uses the welding wire as a stylus to detect deviations between the programmed and the actual weld seam position. The robot guides the welding torch along a search path programmed on the reference component. If the welding wire contacts the component, a measuring current flows and the robot stops the search run. The robot coordinates of the contact point on the programmed component are compared with the coordinates recorded during the search, allowing calculation of the component's actual position. Three search paths in spatial coordinates X, Y and Z relative to the component enable precise adaptation of robot movements to the actual weld seam positions. The accessible free wire end at the torch tip allows programming search paths close to weld seams. Measuring with the welding wire in the joint also enables determination of weld seam volume (e.g. V-seam).

Unique selling points:

• Recognise and compensate component tolerances before welding:
  Improves weld seam positioning by measuring and compensating part deviations.
• No additional attachments required:
  Maintains accessibility of the welding torch without extra fixtures.
• Programmed within the robot sequence program:
  Integration in standard robot programs; no special programming knowledge required.

Characteristics / technical specifications:

• Product model: QR-SN-TS-W
• Brand: CLOOS
• Measuring principle: welding wire used as stylus; contact generates a measuring current
• Measurement axes: three spatial axes X, Y and Z (three search paths)
• Operation: robot follows programmed search paths; contact triggers measuring current and stops the run to record coordinates
• Positioning: compares programmed contact coordinates with measured coordinates to calculate actual component position and adapt robot movement
• Accessibility: free wire end at torch tip enables search paths close to weld seams
• Weld seam analysis: enables determination of weld seam volume (e.g. V-seam) by measurement with the welding wire
• Integration: programmable directly in the robot sequence program without additional attachments or special programming skills
