In the face of the overall improvement of the level of manufacturing, various industries have put forward higher requirements for collaborative robots, including higher load capacity, wider range of work and higher accuracy. With the rapid development of collaborative robots and cutting-edge technologies and the gradual expansion of application scenarios, the technical direction of collaborative robots is tilting towards the direction of high load, large arm span, high flexibility and high intelligence.
High load & large arm span, better working ability
The size of the cooperative robot is generally small, and the load is less than 10kg. Although traditional industrial robots have a large load, they usually need to be equipped with layers of protection for safety considerations. In order to solve the problem that traditional industrial robots can not adapt to the fast and flexible production of small batches and multiple varieties, and it is difficult to interact with field personnel and cooperate safely, high-load, large-arm cooperative robots should be born.
The unique joint mechanism of the FANUC CRX “Industrial” co-robot series can cope with heavy loads and high speed industrial working environments for long periods of time. Among them, CRX-20iA/L model load is 20kg, arm span 1418mm; The CRX-25iA model can carry a maximum weight of 30kg, and the arm span can reach an astonishing 1889mm. The ultra-long arm span can meet the requirements of various palletizing types. When the long arm is operated, the interference area can be reduced, and the parts located behind the robot can be easily retrieved and placed. With the advantages of high load and large arm span, CRX-20iA/L and CRX-25iA have become the ideal choice for palletizing applications in many industries such as food, pharmaceuticals and household chemicals.

With the gradual increase of load, the control difficulty of cooperative robot increases, which brings certain challenges to stability. CRX series collaborative robots use AC servo motor + harmonic reducer, start, acceleration, braking response speed is faster, more stable operation. While increasing the load, the CRX series cooperative robots have strong stability, with repeated positioning accuracy of 0.03mm-0.05mm.

Integration of perception technology to achieve a higher level of intelligence

Perception is the core of collaborative robots. In order to achieve safer and more reliable human-machine interaction, cobots need to have high-precision sensors and powerful sensing capabilities. At the same time, cooperative robots also need to adopt advanced safety technologies, such as collision detection, emergency stop, etc., to ensure safe human-machine interaction.

CRX series collaborative robots have various intelligent functions such as FANUC iRVision 3D intelligent vision function and iRPickTool, built-in torque sensor and vision system, which can achieve accurate positioning and recognition of the surrounding environment. When the robot body is perceived to be in slight contact with humans or other objects, it will immediately stop moving to prevent injury.
Unlock new scenarios for diversified industrial applications

Equipped with a variety of sensors and intelligent technologies, while adapting to a variety of work environments and tasks, collaborative robots provide enterprises with more efficient, safer and smarter solutions, changing the traditional way of working and production processes. From palletizing and welding to accurate and fast picking, screw locking, and intelligent production of man-machine collaboration, the flexibility of collaborative robots is constantly improving, and it is widely used in various industrial subdivisions.

For example, in the face of manual palletizing requires workers to bend over, pick up and rotate their bodies for hours on end, CRX series collaborative robots can quickly adapt to multiple brands of quick-plug equipment and non-standard end actuators, and built-in special palletizing process packages to meet the requirements of different palletizing types. Welding work not only faces the challenge of efficiency, quality and stability, but also faces the problem of recruitment and employment. CRX series collaborative robots have built-in multi-layer multi-channel, contact positioning, arc tracking and other professional welding software functions, with manual traction, laser positioning and other ways to quickly complete weld identification and teaching.

The application field of collaborative robots is also expanding, and it has been promoted from the automobile manufacturing industry and 3C electronics manufacturing industry to other industries, and new scenarios continue to emerge. Under the guidance of the “double carbon” goal, the new energy industry is experiencing unprecedented rapid development and upgrading in the direction of intelligence and digitalization. This also makes the market demand for collaborative robots further increase, and the future development is promising.

With the continuous progress of collaborative robot technology, collaborative robots will be applied and developed in more fields, and will also accelerate the digitization process in the industrial field. CRX “Industrial” collaborative robot series combines the running speed, accuracy and stability of traditional industrial robots with the safe cooperation performance and ease of use of collaborative robots. Fanuc will be driven by industry demand and guided by technology trends, and continue to explore new application scenarios to empower more industries.
