As one of the few companies in China's robotics field that can cover the entire product line of Industrial robots and cobots, ROKAE Robotics has recently raised the payload limit of its industrial robots to a maximum of 220 kg, and the maximum payload of its cobots to 20 kg, so that it has the ability to respond to the needs of the emerging markets of automobiles and photovoltaics, and will be able to provide greater value to its customers in the future in the process of production and manufacturing.
New Product Highlights
Large Payload and Long Reach
ROKAE's newly released NB80 and NB220 series have five models in total, which can meet the production demand of all kinds of payloads from 50 kg to 300 kg in an automobile production line. The NB220 series is the product with longer reach and larger payload in the same class in China.
Wrist Payload Capacity Upgrade
ROKAE Robotics has enhanced the wrist capacity of axis 4, 5 and 6 through the joint payload calibration technology and component structure design technology, which makes NB series products able to perform more stable and higher precision movements for large-size, large-inertia and far-off-center workpieces, which reduces the downtime of the production line and realizes better maintainability. This makes the NB series large payload robots ideal for automotive, photovoltaic, and other industries where large workpieces are handled.
High Speed and High Performance
In terms of overall performance, thanks to ROKAE Robotics' self-developed xCore control system, as well as the continuous improvement of servo and motion control system, ROKAE NB series of large payload robots have typical high beat characteristics, and the high speed performance of all axes is excellent, so that the robots can move the workpieces and place them in the acceleration and deceleration motion in a fast and stable way, which is far better than the performance of the majority of the large payload robots in the high speed section in China. Performance of the robot in the high-speed section is much better than that of most domestic robots with large loads.
High Protection Level
It is also worth noting that the NB80&NB220 series robots have higher protection level, IP65 for the whole machine and IP67 for the wrist, which can help enterprises to maintain high-efficiency production capacity under many kinds of harsh working conditions.
More Application Possibilities
ROKAE NB80 and NB220 series robots are now entering the upstream and downstream of the automobile industry chain with the features of long reach, large payload, strong wrist capacity and high protection level. This makes more applications possible, such as spot welding of automobiles, handling of large-weight lithium batteries, loading and unloading of assembly line, assembly of engine cylinder head, handling of automobile seats, handling of photovoltaic cell baskets, loading and unloading of machine tending, etc.
Large Payload Cobots
The xMate CR20 is ROKAE's latest large payload cobot, with a payload of up to 20 kg and a reach of up to 1,798 mm. xMate CR20 is also able to increase its payload capacity while maintaining high speed and high precision thanks to OptiMotion and TrueMotion, the leading motion control technologies in the industrial field.
Meanwhile, as a large payload cobot, CR20 continues the integrated design of ROKAE xMate series without a controller cabinet and the new generation of joint force control technology system, which is equipped with high-precision torque sensors in each joint, and has the features of 1N ultra-light dragging teaching, sensitive collision detection, graphical programming, etc. It can be widely applied in flexible operation scenarios, such as palletizing, handling, loading and unloading, welding, grinding, assembling, and screw locking.
How to Do Well in Large Payload Robots?
According to ROKAE Robotics Chief Scientist Chris WANG, ROKAE Robotics has 8 years of excellent technology accumulation in the field of robotics, and as early as 2 years ago, it set up an R&D center in Japan, which is able to quickly unite the advanced experience, concepts and methods of Japan R&D center, digest and absorb the world's leading robotics technology, and gradually form a new R&D system with higher quality and higher reliability.
With the new ROKAE R&D system, they analyze in detail the various possible scenarios for customers to make the products closer to the market. ROKAE develops comprehensive and reasonable performance indexes suitable for customers' scenarios and guides the forward design of detailed components of the robots according to the scenarios' requirements. The research and development of large payload robot is finally completed with high performance and high reliability.
Meanwhile, ROKAE has adopted a highly efficient simulation system to support the development of large payload robots in a sustainable way.
Conclusion and Future
At present, ROKAE Robotics has realized the full product portfolio from 3 kg to 220 kg payload, the industrial robot product line covers 4 kg to 220 kg payload, and the flexible cobot product line has three major product series, ER, CR and SR, with payloads ranging from 3 kg to 20 kg.
In the future, ROKAE will also launch products with larger payloads of 300 kg or more, to make ROKAE more competitive in a wide range of application scenarios and increase market share, and contribute to global intelligent manufacturing.
