Advanced Engineering Industrie's MOV 650 four-axis pick and place robot is used to position PCBs between conveyors and processes such as etching.
The design of the robot system called for low cost combined with maximum flexibility to adapt to any size of PCB and the ability to meet high processing speeds with long life and minimal maintenance.
Advanced Engineering Industrie based its design on a SCARA style robot system with one linear axis and three rotary axes, all acting in the same horizontal plane.
The robot can transport up to 12 circuit boards per minute, handling two magazine-mounted PCBs simultaneously - each measuring up to 650 x 650mm with a combined weight of 4kg.
To minimise the overall inertia it was decided to use a low-mass power transmission system comprising 12 Synchroflex Gen III polyurethane timing belts with hardened precision pulleys and servomotor drives.
The choice of the GEN III timing belt with its harder polyurethane and improved steel cord tensioning allows up to 25% more power transmission than conventional belts, resulting in higher load performance and an extended lifetime.
The belt offers a constant length and no post-elongation, maintaining a very high dynamic stiffness to provide optimal servo control characteristics and exceptional accuracy and repeatability.
The red GEN III belt requires no lubrication, is very quiet running and is effectively maintenance-free after installation.Jan 3, 2008
