Prevent Dispensing Nozzle Crashes with Adaptive Z-Offset Feedback

Coherix 3D Inspection for Sealant Dispensing Applications

Part variation is a reality in manufacturing: but nozzle destruction doesn’t have to be. In automated dispensing and material application, even slight changes in part height can lead to costly nozzle crashes, unplanned downtime and damaged equipment.

With adaptive Z-offset feedback, robots can automatically adjust height in real time to account for part variation. Instead of following a fixed path, the robot responds dynamically to actual conditions on the line, maintaining the correct standoff distance and protecting critical tooling.

In a recent body shop application, this adaptive approach:

  • Eliminated nozzle crashes
  • Avoided production downtime
  • Saved over $270,000 in costs

By enabling real-time height adjustment, manufacturers can improve process robustness, extend nozzle life and significantly reduce maintenance and scrap costs, without slowing production.
