How to cut your robotic system down to size Edited by Mike Santora • Managing Editor
METAL LS, the Bulgarian manufacturer of door locking systems, door and window handles, and building hardware started planning the new automated assembly of door locks in 2019. The robotic systems the company already used for other applications were too large for the planned production site, so the new solutions needed to be as compact and precise as possible, in addition to being state of the art. Door and security locks are precision parts with standard dimensions and components stipulated in DIN standards. Therefore, quality and precision were critical deciding factors for METAL LS. The robots also needed to achieve high productivity — assembling between 10 and 14 locks per minute. Additionally, the company required a high level of flexibility and the possibility of retooling to reuse the same system to 26

produce new locks in the future. Following a comparison of various manufacturers and products, METAL LS opted for a robot system om Delta. It was the only manufacturer to offer a complete solution including programmable logic controllers (PLC), a human-machine interface (HMI), servo systems, and robotic arms with Machine Vision. To implement this project, METAL LS and Delta collaborated to develop a custom workstation for the assembly of the mechanical door lock components. The main part of the system comprises a rotation table on which seven, six-axis DRV90L7 articulated DESIGN WORLD
