Positioning

Parts Positioning and Robotic Guidance

For inspection on high-speed production lines, offline verification audits or robot-guided pick and place, positioning tools are critical to successful machine vision. Positioning tools, locators or pattern finders recognize and determine exact position and orientation of parts. Results can be transferred directly to material handling devices or used to position other tools required for the inspection. We refer to this correcting for part movement as landmarking.

Precision Alignment Capabilities

Teledyne DALSA's products provide a variety of positioning tools that range from simple edge finders to sophisticated pattern finding algorithms. Selecting the appropriate positioning tool (or tools) for a specific application is typically based on the following criteria:

  • Part Features: high contrast unique features or complex similar patterns
  • Part Movement: XY only or with rotation
  • Part Appearance: pattern variation due to process or environment changes
  • Part Orientation: small rotation or 360° rotation
