Energy-saving robots promise ‘class-leading repeatability’

27 June, 2023

ABB Robotics has added four new energy-saving models and 22 variants to its family of large robots, claiming that they will achieve energy savings of up to 20%. The new IRB 6710, 6720, 6730 and 6740 models are suitable for payloads from 150–310kg and have reaches from 2.5–3.2m. They made their debut at the Automatica exhibition in Munich, Germany, where they were shown performing spot welding, loading and unloading tasks in a fully functional battery production cell on ABB’s stand.

The improved energy efficiency is achieved using ABB’s OmniCore controller in combination with robot designs that up to 10% lighter. The controller also delivers high motion control accuracy, achieving a “class-leading” repeatability with a minimum deviation of 0.03mm, according to ABB. These capabilities make the modular robots ideal for complex tasks such as spot and laser welding, screwdriving and riveting, allowing automotive manufacturers, in particular, to achieve high-quality assemblies.

According to Marc Segura, president of ABB’s Robotics Division, the new robots respond to customer’s needs, “offering more choice and greater flexibility for more sustainable production. These new robots will help our customers build resilience across a range of industries including automotive, general manufacturing, foundry, food and beverage, and logistics.”

“Our new robot range meets the needs of the rapidly growing electric vehicle (EV) industry,” adds Joerg Reger, managing director of ABB Robotics Automotive business. “As manufacturers ramp up production of EVs and batteries, they can choose from a wide range of ABB robots to ensure they have the right variant to handle batteries of varying sizes, from individual cells and modules to complete packages. They can also perform tasks such as high-precision car body assembly and spot welding and enter restricted areas within a vehicle to install seats or dashboards.”
