ABB IRB 120 OverviewThe IRB 120 is the smallest multipurpose robot in ABB’s fleet of industrial robots. ABB recognized the robot industry at the time was lacking in small robot options. Releasing the ABB IRB 120 paid off as it is one of ABB’s most popular robot models and has enjoyed tremendous success as the demand for small industrial robots has exploded. This articulated robot features a payload capacity of just 3 kg for lightweight part handling. Its compact size and short arm with a reach of 580 mm makes it suitable for operating in tight spaces. It is built with aluminum for an incredibly light robot mass of 25 kg allowing it to be easily mounted almost anywhere including overhead, wall, or even on top of other manufacturing machines. The IRB 120 is comparable to the FANUC LR Mate 200ic, Yaskawa Motoman MH3F, and KUKA KR5 R650 from ABB’s competitors.
The ABB IRB 120 is one of the most versatile small robots on the market. It can automate several different applications including automated material handling, robotic assembly, packaging, part transfer, pick and place, and palletizing. This six axis robot is available with a food grade lubricate option which makes it safe for operation in cleanroom facilities including those in the food, medical, pharmaceutical, electronic, and research industries.
Automating with the ABB IRB 120 is sure to decrease cycle times with its fast and agile movements. This robot can complete a cycle in just 0.58 seconds. Its repeatability of 0.01 mm ensures that even with its fast-operating speeds, accuracy is never compromised. In addition to its fast-operating speeds, the IRB 120 features an optimized work envelope despite its short reach. This robot is considered to have the best stroke in its class and the capability to reach up to 112 mm below its base.
In 2012, ABB released an even faster version of the IRB 120 with the IRB 120T. The IRB 120T features the same specifications as the standard model but with increased speed capabilities in its fourth, fifth, and sixth axes. The increase in speed cuts down cycle time completions by 10% compared to the standard IRB 120.
The ABB IRB 120 is easy to maintain with internal cable routing. Internalized cabling reduces interference, wear and tear, maintenance time, and costs. This combined with its reduced footprint makes integration easy and compatible with most production lines. Manufacturers with limited space can still automate using the ABB IRB 120. Space savings is one of the biggest advantages of small robot automation as it removes size barriers for manufacturers.
