The Laboratory for Machine Tools and Production Engineering (WZL) at RWTH Aachen University has installed a Reis Robotics laser welding system for development of batteries for electro-mobility. The complete RWTH system, of which the Reis welding machine is a part, allows engineers to optimise the complete manufacturing process, from electrode coating to the production of the battery pack.
The Reis laser welding system consists of an articulated arm robot RV60-60, a 180° rotary table for setting and removal of components, a rotary module for manipulation of components, as well as a laser-safe perimeter guard.
A TruDisk disk laser made by Trumpf with programmable focusing optics (PFO 3D) is used as laser source. The robot cell can be visualised via the offline programming tool ProVis. With this tool, it is possible to check possible component accessibilities and cycle times in advance as well as to create new programs while the system is operating. Education and on-going training of engineers is also part of Reis’ activities at the WZL.
