Articulated advantages

The IRB 6620LX is a 5-axis overhead mounted robot arm on a linear axis unit providing flexibility in production with its 150kg payload and large scalable workspace.

Said to be ideal for machine tending and material handling applications, the IRB 6620LX offers greater versatility and cost effectiveness compared to customised linear handling systems. The IRB 6620LX is also suitable for applications such as power train assembly, heavy arc welding and grinding.

To integrate articulated and linear technology, ABB has removed the first rotational axis from the robotic arm, enabling it to be mounted either upside down or sideways on the linear gantry unit, which acts as the first axis. The ability to be mounted overhead facilitates production flexibility as the linear gantry axis unit can be extended by up to 33m horizontally and 4m vertically.

With this extended reach, the robot can access several machines or workstations without compromising on performance, resulting in high productivity and machine utilisation. The flexibility and work space of the IRB 6620LX can be further enhanced through additional processes, such as inspection and deburring in addition to basic material handling tasks to further improve robot utilisation.

The inherent flexibility also enables quick and easy changeovers for improved production uptime and provides opportunities for the solution to be tailored for different applications.

The IRB 6620LX also enables savings in investment and maintenance, as only one robot is needed to replace numerous complex materials handling systems. It can be readily fitted or adapted to existing production lines as it requires limited floor space requirements and can be configured to position the support legs to suit the application.

The use of standard, well proven components guarantees high performance and reliability and ABB reports that the speed and acceleration on the linear axis secures the shortest possible cycle times with highest possible accuracy, even at large distances and with a full payload. The high performance is delivered as a result of sophisticated mechanical engineering and ABB's motion control technology, TrueMove and QuickMove.

In machine tending applications the IRB 6620LX offers excellent handling possibilities as it can access machines either from the top or the side. In addition, overhead rail mounted robots provide open access in front of machines for manual operation, maintenance work, handling of short batches and quick changes. As a result, personal safety is improved, as the robot is not present if there is a need to operate machines manually.

The IRB 6620LX's 5-axis robot arm is available with ABB's established Foundry Plus 2 protection, which includes IP67 for the entire arm. The linear gantry axis has IP66 protection as standard.

The new robot is available with ABB's IRC5 robot controller and is fully supported by the ABB Robotics global sales and service organisation in 49 countries and over 100 locations.
