Solution
In order to find the best possible solution to this problem, two versions with different plain bearing components were designed:
in version 1, the 48 suction tips were each guided by two
drylin N carriages in a cross formation. These carriages run in
drylin N guide rails (NK-02-17).
In the second test design, they were replaced by
drylin slide bearings (JUM-02-10) and
drylin R linear shafts (AWMP-10).
Both versions deliver results of equal quality. The AWMP-10 shafts are freely supported at their ends and have a higher rigidity. In both versions, the system with
drylin slide bearings (JUM-01-12) and
drylin R linear shafts (AWMP-12) guides the rows of suction nozzles in a 6 x 8 formation. Both module types were assembled on the robot arm using a quick-clamping system based on
drylin W housing bearings (WJ200UM-01-20-AL) bearing blocks and
drylin W double guide rails (WS-20-80).
