SCARA robot sets new performance benchmarks

31 July 2012

Mitsubishi Electric has extended its RH range of MELFA SCARA robots with the F series, which is said to set new benchmark standards for speed, flexibility, ease of integration and simplicity of programming.

Combining a wide area of coverage with fast cycle times, the F series is said to offer a cost-effective way to boost productivity on critical production lines.

The F series includes two base models with various options. The RH-3FH, for example provides a 3kg payload, while the RH-6FH provides a 6kg maximum payload. Both feature a 12in test cycle time of just 0.29 seconds. For increased flexibility in operation the working range for the J1 axis on these robots has been increased, allowing a reachable area from ±127° to ±170° to be achieved with just one arm configuration.

For use in challenging environments, the F Series provides increased protection as standard for the spindle throughout the housing, and in the most demanding applications the protection level can easily and cost-effectively increased to IP65. In addition, all wiring is routed internally through the spindle, further increasing applicability in demanding environments as well as increasing long term reliability and reducing maintenance requirements by eliminating the possibility of the cables tangling.

The robots include Ethernet, USB, tracking functions, camera interface, hand I/O and additional-axis connections as standard. They have a standalone controller unit as standard, and are also available as a fully integrated package where the robot controller is embedded in an iQ Platform module for direct integration with Mitsubishi PLCs and PACs.

Offline programming is simple via Mitsubishi’s RT ToolBox2 PC-based software for programming, monitoring and debugging, or through MELFA Works 3D robot and working cell programming and simulation software which helps the user to check the complete program for errors or collisions before it is run in the real application.
