Cleanroom robot redesigned for compact situations

ABB Robotics' ISO 5 (Class 100) Cleanroom version of the IRB 120 robot is a multipurpose 6-axis robot designed as a more compact solution to the existing model of the IRB 120 that has already been released.

Courtesy: ABB RoboticsABB Robotics has introduced an ISO 5 (Class 100) Cleanroom version of the IRB 120, its smallest ever multipurpose 6-axis robot. The component materials of the IRB 120 prone to particle generation have been modified to eliminate the potential for contamination of the manufacturing area and the parts being processed.  

Cleanrooms are classified according to the number and size of particles permitted per volume of air, with Class 100 denoting the number of particles of size 0.5 µm or larger permitted per cubic foot of air. Cleanroom robots of this rating are suited for material handling and assembly applications in a range of industries requiring low levels of environmental pollutants, including medical device, pharmaceutical, electronics, semiconductor and solar panel manufacturing.

The Cleanroom IRB 120 features a special 4-layer paint with varnish clear coat for easy, cloth cleaning; unpainted mounting holes; unpainted stainless steel mechanical stops; and special glue-seals to avoid particle generation. In certain conditions it can meet more stringent, ISO 4 (Class 10) requirements. The new model has all the functionality of the standard IRB 120, with superior motion control and outstanding path accuracy, providing agility, precision and speed to applications where a smaller footprint and profile are required. Weighing just 25kg (55 lbs), the IRB 120 has a standard payload of 3kg (6.6 lbs), a vertical wrist payload of 4kg (8.8 lbs), a reach of 580mm, a best-in-class stroke of 411mm and the ability to reach 112mm below its base. 

The standard version of the IRB 120 was introduced in Fall 2009. All models are:

  • Extremely accurate 6-axis robot with a repeatability of pose (RP) of 0.01 mm; competitive 6-axis robot models feature an RP of 0.02 mm.
  • Easy to integrate into new and existing lines. It can be mounted at any angle, either in a cell, on top of a machine or in close proximity to other robots on the line. Wall- and invert-mounting saves floor space and optimizes working range.
  • Extremely nimble, featuring a compact turning radius on axis 1, allowing it to be mounted close to application process machines.
  • Easy to clean and maintain with internal cabling and smooth surfaces.
  • Designed with a light, aluminum structure, with powerful motors that ensure fast, accurate acceleration.

The Cleanroom IRB 120 is available with the compact version of the IRC5 controller, making it easy to program and control for a variety of tasks. The Compact IRC5 is fully compatible with the standard and panel mount IRC5 controllers, with user friendly FlexPendant programming, RobotStudio offline programming, flexible RAPID language and powerful communication capabilities.
