ABB has launched the IRB 6620LX, a five-axis overhead-mounted robot on a linear axis unit that is said to combine the advantages of an articulated robot and a linear gantry for improved cycle times.

The IRB 6620LX is said to provide flexibility in production with its 150kg payload and large, scalable workspace.

Ideal for machine tending and material handling applications, the IRB 6620LX is claimed to offer greater versatility and cost effectiveness compared with 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 performance, resulting in high productivity and machine utilisation.

The flexibility and workspace of IRB 6620LX can be exploited through additional processes, such as inspection, deburring, packing or gluing in addition to ‘basic’ material handling tasks to further improve robot utilisation.

This flexibility is also said to enable quick and easy changeovers for improved production uptime and provides opportunities for the solution to be tailored for different applications.

The IRB 6620LX is also claimed to enable 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.

The speed and acceleration on the linear axis is said to secure the shortest cycle times with highest accuracy, even at large distances and with a full payload.

The performance is delivered as a result of mechanical engineering and ABB’s Truemove and Quickmove technology.

In machine-tending applications, ABB said the IRB 6620LX offers better handling possibilities compared with conventional solutions as it can access machines 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 five-axis robot arm is available with ABB’s Foundry Plus 2 protection, which includes IP67 for the entire arm.

The linear gantry axis has IP66 protection as standard.

The robot is available with ABB’s IRC5 robot controller.
