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 settings. These robots can perform tasks automatically, using their own power and control systems. They can be programmed to follow specific instructions or controlled by humans. Modern industrial robots often incorporate artificial intelligence, enabling them to adapt and improve over time.
2. Components of an Industrial Robot
Industrial robots are composed of three main parts: the mechanical structure, the drive system, and the control system.
The mechanical structure includes the base, arms, wrists, and hands, sometimes with additional mobility mechanisms. Most robots have between 3 to 6 degrees of freedom, with the wrist typically having 1 to 3 degrees of movement.
The drive system consists of power units and transmission mechanisms that enable the actuators to perform actions. The control system sends commands to the drive and actuator systems based on pre-programmed instructions.
3. Types of Industrial Robots
Mobile robots (AGVs) are computer-controlled machines used for navigation, sensor-based operations, and network interaction. They are widely used in manufacturing, logistics, and automated warehouses.
Spot welding robots are known for their stability, speed, and high load capacity. They are commonly used in automotive production lines and are essential for improving welding efficiency.
Arc welding robots are used in various automotive parts manufacturing. They are often supplied by large manufacturers to equipment suppliers.
Laser processing robots combine robotic technology with precision laser systems to allow flexible and accurate operations in manufacturing environments.
Vacuum robots operate in controlled environments such as semiconductor fabrication, where they handle delicate materials without contamination. These robots are critical in advanced manufacturing and face import restrictions in many countries.
Clean room robots are used in environments requiring strict cleanliness, such as pharmaceuticals and electronics, ensuring contamination-free operations.
4. Industrial Robot Industry Chain
The upstream of the industry involves core components like reducers and controllers, which are crucial for robot functionality. The midstream focuses on the robot body, while the downstream includes system integrators, where most domestic companies operate.
In China, key components such as gearboxes, servo motors, and controllers account for a significant portion of the cost. However, domestic development in these areas lags behind international standards, leading to reliance on imports and higher production costs.
5. Analysis of Leading Robotics Companies
The robotics sector is highly competitive, with many new entrants. In 2016, three Chinese companies were featured among the top 50 global robotics firms. These include DJI, Foxconn, and Siasun Robot & Automation.
International leaders such as ABB, Google, and Amazon also play significant roles in shaping the future of robotics through innovation and investment.
6. Market Trends and Growth
China's industrial robot market has seen rapid growth, with over 75,000 units sold in 2015, representing about 30% of the global market. The demand for automation continues to rise across industries, including automotive, electronics, and logistics.
The 3C industry, though currently low in robot density, shows strong potential for growth. The automotive sector remains the largest application area, driven by both OEMs and component manufacturers.
7. Future Trends in Robotics
Robots are evolving toward greater safety, ease of use, and intelligence. Three major trends are expected to shape the next decade:
- General software platforms will reduce the complexity and cost of robot programming, making it more accessible to small businesses and individuals.
- Human-robot collaboration will become more common, allowing robots to work alongside humans in shared spaces, enhancing productivity and flexibility.
- Machine vision and deep learning will make robots smarter, enabling them to learn from experience and adapt to changing environments.
Conclusion
As China moves toward intelligent manufacturing, industrial robots are playing a vital role in transforming traditional industries. With increased automation, the workforce is shifting toward higher-value tasks, driving economic growth and innovation. The future of robotics looks promising, with continued advancements in technology and broader applications across sectors.
