Large robots target EV production and other complex tasks

04 April, 2022

ABB has announced two new families of large industrial robots for complex manufacturing applications such as EV (electric vehicle) manufacturing, foundries, forging, rubber, plastics and metal fabrication. The IRB 5710 and 5720 robots are designed to boost productivity, performance and uptime by delivering enhanced speed, accuracy, flexibility, and a more robust design with integrated cabling.

Available in eight variants, the robots offer payloads from 70–180kg and reaches from 2.3–3m. They are suitable for tasks such as material-handling, machine tending and assembly, as well as EV-specific operations such as battery module picking and placing. They can also be used for plastic moulding, metal casting, cleaning and spraying applications. More applications, including welding, cutting and dispensing, will be released during 2023.

The IRB 5710 covers payloads from 70–110kg and reaches from 2.3–-2.7m, while the IRB 5720 spans 90–180kg and 2.6-3m.

“These new robots accelerate ABB’s continuing expansion into the rapidly growing EV market, meeting customer demand for robust units with the speed, path accuracy and dexterity to handle complex EV battery assembly duties,” says Joerg Reger, managing director of ABB Robotics’ automotive business. “The switch from ICE (internal combustion engine) vehicles to EVs especially is driving increased demand for fast, adaptable production lines. EV designs can often be highly complex, and components such as batteries and semiconductor modules can be very heavy or extremely fragile. These demands call for solutions that can offer maximum precision and repeatability to avoid errors in production.”

Both robot families are powered by ABB’s new OmniCore V250XT controller which allows them to offer “class-leading” speed and accuracy, improving production capacities and shortening manufacturing times. ABB promises a position repeatability of 0.04-0.05mm, a path repeatability of 0.1-0.14mm and a path accuracy of 1-1.2mm.

ABB’s new heavy-duty robots are aimed at demanding applications such as moving battery packs in electric vehicle production

Process cables can be routed internally through the robot’s upper arm and along the wrist, eliminating swinging cables, and protecting them against heat and collisions – a common cause of robot maintenance issues – potentially cutting downtime and maintenance costs and extending the robots’ service lives by several years. Software is available for programming and simulating cable movements.

The robots offer multiple mounting possibilities including floor, angled, inverted and semi-shelf options.
