With the continuous advancement of automation, the demand for robots in factory production lines is increasing day by day. In recent years, global robotics giant ABB has closely followed the pulse of the market and launched a series of innovative products. Recently, ABB Robotics has expanded its product lineup of modular industrial robot arms and launched two robots, IRB 7710 and IRB 7720, which offer 16 new variants designed specifically for various applications.

Module design

Traditional industrial robots are usually designed in a single way and cannot meet the differentiated needs of different application scenarios. ABB's modular robots break this constraint by standardizing and modularizing components such as the base, lower arm, upper arm, and wrist, making it easy to assemble dozens of different models and specifications.

All models share the same footprint and interface specifications, greatly simplifying the installation and 

debugging process and improving production flexibility. The factory can freely select the most suitable model according to different payload requirements. The ABB modular series can cover a payload range 

of 70 kilograms to 620 kilograms, with a total of 46 variants available to meet the needs of the vast majority 

of scenarios.

This advanced modular design concept is not only beneficial for reducing robot costs and shortening 

delivery cycles, but also enables efficient switching of robot models on the production line, achieving 

fast product switching and small batch customized production. When faced with small batch orders of 

multiple varieties, factories do not need to purchase new robots repeatedly, only need to replace some 

components, greatly improving asset utilization and avoiding the waste of repeated investment.

Accurate and efficient

ABB's newly launched IRB 7710 and IRB 7720 large modular robots have a path accuracy of up to 0.6 

millimeters and a maximum operating speed of 1600 millimeters per second, making them the best in terms 

of accuracy and speed among similar products. This is crucial for high-precision machining processes such as 

automotive stamping, casting palletizing, and precision machining, which can significantly improve production efficiency and product consistency.

It is worth mentioning that ABB modular robots all adopt mechatronics design, tightly integrating control 

systems, motors, and sensors, greatly simplifying wiring and installation, and improving reliability. Compared 

with traditional wired control, this design enables the robot to achieve more precise and smooth motion 

control, ensuring the precision of various complex machining processes.

Widely used

The ABB modular robot series has a deep product lineup that can meet the different needs of various fields 

in the manufacturing industry. According to ABB's forecast, the new model may be mainly applied in 

industries such as automotive OEM and first tier suppliers, logistics, casting, machinery manufacturing, 

construction, and agriculture.

Taking the automobile manufacturing industry as an example, there are many processes on the automobile 

production line, such as stamping automation, body welding, battery structure assembly, and final assembly, 

which have different requirements for the effective load and accuracy of robots. The ABB modular robot 

series can be tailored to these different scenarios to create ideal configurations.

In addition, ABB modular robots can be widely used in general heavy-duty handling scenarios, such as steel smelting, machine tool processing, etc., and can also be used in high-precision machining fields, such as 

electronic circuit board soldering, medical equipment precision assembly, etc., playing an irreplaceable role.

Marc Segura, President of ABB Robotics Division, said, "We have designed a modular portfolio of large 

robots that allows them to choose the best robots and variants, enabling them to operate effectively. With 

the most comprehensive mechatronics platform, industrial robots, collaborative robots, and AMR product 

portfolio on the market, the latest robots further expand our product portfolio, helping our customers 

address labor shortages, ensuring they remain competitive, and operating in a sustainable manner“
