AccuBeam: Robot Temperature Compensation & TCP/Robot Mastering Recovery System
Manufacturers today rely more and more on industrial robots for efficiency and quality. 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 AccuBeamTM (also
known as AutoCalTM Series 2) system offers an inline 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 AutoCal Series 2 system can detect drift or sudden changes to the robot structure itself (including joint offsets) as well
as its T ool 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 AutoCal Series 2 System - Maximum Quality and Uptime at a Minimum Cost
· Automatic
correction of robot temperature variations
· Full re-calibration of a “bent” tool (TCPx,y
,z and orientation)
· Fast recovery after a robot crash or motor replacement
(joint offset re-mastering)
· Constant automatic monitoring of the robot’s performance
· All that, while controlling quality and drastically minimizing any production downtime!
The AutoCal Series 2 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 AutoCal Series 2 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 AutoCal Series 2 System - How it works
The AutoCal Series 2 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 AutoCal software,(2) twin beam lasers, and (3) a rugged industrial sensor. The AutoCal Series 2 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 TCPcan then be automatically
corrected through the AutoCal Series 2 System’s compensation process. Finally, the
AutoCal system confirms the accuracy of the
corrected robot and its TCP , to ensure consistent quality and process control.
