Robots used for welding, cutting, material handling, dispensing, and assembly must operate at very high levels of reliability and repeatability/accuracy to meet the demands of modern manufacturing.  This means that any environmental changes or mechanical failure of the robot system - whether the robot itself or any of its peripherals - can result in many hours of lost production or can generate large amounts of scrap parts.

The AccuBeam system offers an in-line robot calibration solution designed to quickly and automatically guarantee the performance of robotic equipment.  Adaptable to a wide variety of robotic applications and compatible with most robot types, the AccuBeam system can detect drift or sudden changes to the robot structure itself (including joint offsets) as well as its Tool Center Point (TCP), and then automatically correct for those changes without any operator intervention.  This means "no guessing" of what went wrong; no valuable time wasted re-teaching robot programs, and no loss of production quality!

The AccuBeam System - Maximum Quality and Uptime at a Minimum Cost

  • Automatic correction of robot temperature variations
  • Full re-calibration of a "bent" tool (TCP x,y,z and orientation)
  • Fast recovery after a robot crash or motor replacement (jpoin offset re-mastering)
  • Constant automatic monitoring of the robot's performance
  • All that, while controlling quality and drastically minimizing any production downtime!

The AccuBeam System - Dynalog's State-of -the-Art Calibration Technology
Dynalog is the world leader in robot cell calibration technology.  Its mainstream product - the DynaCal system - is used for off-line robot cell calibration, and has been accepted by many major robot manufacturers and end-users as the most accurate and technically advanced robot calibration process available. The AccuBeam system incorporates the proven calibration technology of the DynaCal product into an in-line, fully automated system designed specifically for process monitoring, repeatability control, and recovery purposes.

The AccuBeam System - How it works
The AccuBeam System comes in different forms, depending on the particular robot controller and its level of integration (contact Dynalog for more information).  However, a typical installation consists of (1) the AccuBeam software, (2) twin beam lasers, and (3) a rugged industrial sensor.  The AccuBeam System relies on simple and automatic measurements: no special artifact or interface required!  Between production cycles, the robot automatically executes - in a matter of seconds - a "Quick-Check" measurement routine to assess overall system performance and to detect any drift or crash of the robot or TCP.  Any changes to the robot structure or TCP can then be automatically corrected through the AccuBeam System's compensation process.  Finally, the AccuBeam system confirms the accuracy of the corrected robot and its TCP, to ensure consistent quality and process control.
