In-depth analysis of the entire industrial chain of industrial robots
1. What is an Industrial Robot?
An industrial robot is a multi-jointed or multi-degree-of-freedom machine designed for use in industrial environments. These robots are capable of performing tasks automatically, relying on their own power and control systems to carry out various functions. They can be programmed by humans or operate based on pre-set instructions. In modern applications, they often incorporate artificial intelligence principles to enhance their capabilities.
2. Components of an Industrial Robot
Industrial robots typically consist of three main components: the mechanical structure, the drive system, and the control system.
The mechanical structure includes the base, arms, wrists, and hands, and some models may also feature walking mechanisms. Most industrial robots have between 3 to 6 degrees of freedom, with the wrist usually offering 1 to 3 degrees of movement.
The drive system consists of a power source and transmission mechanisms that enable the actuators to perform specific actions. The control system sends commands to the drive system and actuators according to a pre-programmed sequence, ensuring precise operation.
3. Types of Industrial Robots
Mobile robots (AGVs) are computer-controlled machines used for tasks such as navigation, sensor-based control, and network interaction. They are widely applied in industries like manufacturing, electronics, and logistics for material handling and automated operations.
Spot welding robots are known for their stability, large working space, and high load capacity. They significantly improve productivity and welding quality compared to manual methods, especially in automotive manufacturing.
Arc welding robots are commonly used for welding auto parts. International manufacturers often supply these units to equipment suppliers in the industry.
Laser processing robots combine robotics with laser technology to achieve more flexible and accurate operations. Vacuum robots function in controlled environments, particularly in semiconductor manufacturing for wafer handling.
Clean robots operate in cleanrooms, essential for producing high-precision products in industries like electronics and pharmaceuticals.
4. Industrial Robot Industry Chain
The industrial robot industry chain starts with core components such as reducers and controllers, which act as the "brain" of the robot. The midstream involves the robot body, while the downstream includes system integrators, where most domestic companies are concentrated.
Key components like gearboxes, servo motors, and controllers account for significant portions of the cost. However, China still relies heavily on imported parts due to technical limitations, affecting the competitiveness of domestic robots.
5. Analysis of Industrial Robot Companies
The global robotics sector is highly competitive, with many new startups emerging. According to RBR50, several Chinese companies were listed among the top 50 robotic firms, including DJI, Foxconn, and Siasun.
International leaders like ABB, Google, and Amazon are also shaping the future of robotics through innovation and investment. Collaborative robots, machine vision, and AI integration are key trends driving the next wave of development.
6. Market Growth and Trends
In 2015, China accounted for about 30% of global industrial robot sales, reflecting strong growth. The automotive and 3C industries remain major markets, with increasing adoption across sectors like food, textiles, and healthcare.
Looking ahead, trends like general software platforms, human-robot collaboration, and deep learning will transform how robots are used, making them safer, easier to operate, and more intelligent.
Conclusion
As China moves toward smart manufacturing, industrial robots play a vital role in enhancing efficiency and reducing labor costs. With ongoing advancements in AI, automation, and collaboration, the future of robotics looks promising, opening up new opportunities across industries.
