Measuring with KUKA LBR iiwa for FARO
Contactless measurement for quality assurance
Contactless measurement and component testing in human-machine cooperation (HRC) with KUKA LBR iiwa
This mobile robot-scanner combination combines the FARO Factory Array Imager with a collaborative robot from KUKA and thus provides a ready-to-use, flexible solution for inspection in and on the production line.
FAUDE’s task in this project was the design and construction of the HRC solution with a cobot. From the concept to the programming to the safety assessment and the final force measurementaccording to TS 15066.
Thanks to the turntable integrated in the instrument trolley, even more complex components can be captured from several sides. The overlapping images are simply “pinned together” after the measurement in order to measure the entire component completely.
The FARO measuring head works with so-called blue light technology and records millions of 3D coordinate measuring points within seconds. The non-contact measurements enable measurements of up to 0.01 mm, which is sufficient for the usual measurements in the automotive industry. The applications are typically quality inspection, factory automation and dimensional inspection as part of the manufacturing process.
Typical fields of application for measurement as an HRC solution
Today in many companies the measurement technology takes place in different places. From an economic point of view, it is advantageous if a Measuring system can be used in a wide variety of scenarios. The solution presented here solves this requirement by combining a scanner, robot and transportable platform with an integrated turntable.
The integrated rotary table brings the workpiece to be measured into the correct position so that the scanner on the KUKA LBR iiwa can carry out an optimal measurement. The air conditioning from Rittal integrated into the table ensures that the electronic components do not overheat during long periods of use, even in midsummer.
Commissioning the system
The KUKA robot is either programmed via the touch panel or can be moved manually in freedrive mode. In this case, the operator has a handle on the front end of the robot that can easily move the KUKA LBR iiwa into different positions. In this way, processes can be taught in that will later run in practice as an automatic measuring routine. With this approach, this application also meets the requirements of Industry 4.0. With this system, the user can measure a component without his constant presence. However, he also has the option of following the measurements directly on the system.
The operating instructions, the declaration of incorporation and the preparation for the CE documentation were created in cooperation with FARO. The measurements of the limit values according to TS 15066 were also carried out by means of a force-pressure measuring system for collaborative robots from GTE’s measuring device, so that the customer can decide, depending on his environment, whether he wants to work with an additional Sick floor scanner or the system as a complete HRC Want to operate the application.
This HRC application can be used for inspection applications on the production line so that this solution meets the principles of lean manufacturing by eliminating movements and time expenditure that are not necessary.
