What are the applications of flexible force-controlled robots in assembly?

With the continuous development of industrial automation, flexible robots, as an emerging technology, have gradually been widely used in the field of assembly. Its highly sensitive force perception, adjustable compliance control, and strong environmental adaptability make it show unique advantages in complex assembly tasks. This article will discuss in detail the application of flexible force control robots in assembly, and analyze their technical characteristics, application scenarios, advantages, and challenges from multiple aspects.

1. Technical characteristics of flexible force control robots

High-precision force sensors: The core of flexible force control robots lies in their high-precision force sensors, which can monitor the force changes between the robot and the external environment in real-time. By feeding this data back to the control system, the robot can accurately control and adjust the force to ensure stability and accuracy during the assembly process.

Dynamic modeling and control algorithm: In order to achieve precise control of force, flexible robot adopts advanced dynamic modeling and control algorithms. These algorithms can calculate the best force control strategy in real-time according to the dynamic characteristics of the robot and the changes in the external environment, ensuring that the robot can flexibly respond to various situations during the assembly process.

Force-position hybrid control: Another important feature of flexible force-control robots is their force-position hybrid control capability. This control method allows the robot to control position and force at the same time, that is, while maintaining position accuracy, it adjusts its own movements according to changes in external forces. This control method is particularly important for assembly tasks that require fine operation and high flexibility.

2. Application of flexible force-controlled robots in assembly

Automobile manufacturing: In the automotive manufacturing industry, flexible robots are widely used in the assembly process of parts. For example, on the engine assembly line, robots need to accurately install various parts on the engine. Due to the tolerance and position deviation between parts, traditional industrial robots have difficulty dealing with this situation. The flexible force-controlled robot can simulate the human hand's compliance with position deviation through active compliance control to achieve smooth assembly when encountering part tolerance or position deviation through its force-position hybrid control capability. This not only improves assembly efficiency but also ensures assembly quality.

Electronic manufacturing: In the electronic manufacturing industry, flexible force-controlled robots also play an important role. For example, in the process of assembling mobile phones, robots need to accurately install tiny parts on the motherboard. Because these parts are very small and fragile, they require extremely high assembly accuracy and force control. Flexible force-controlled robots can achieve precise assembly of these tiny parts through their high-precision force sensors and advanced control algorithms while avoiding damage caused by excessive force.

Aerospace manufacturing industry: In the aerospace manufacturing industry, flexible force-controlled robots are used for the assembly and maintenance of aircraft parts. Since aircraft parts are usually large and complex in shape, they require extremely high assembly accuracy and flexibility. Flexible force-controlled robots can complete high-precision assembly tasks in complex space environments through their strong environmental adaptability and force-position hybrid control capabilities. In addition, during aircraft maintenance, the robot can also adjust its own movements by sensing the force changes of the maintenance object, thereby achieving more efficient and safer maintenance operations.

Other fields: In addition to the above fields, flexible robots are also used in many fields such as home appliance manufacturing and medical equipment production. In these fields, flexible force-controlled robots bring higher efficiency and better quality to the assembly process through their unique technical characteristics and advantages.

3. Advantages of flexible robots

Improve production efficiency: Flexible force-controlled robots can significantly improve production efficiency by reducing manual intervention and increasing the degree of automation. During the assembly process, the robot can work continuously without being affected by fatigue, and its high-precision force control and position control capabilities can also reduce the defective rate and rework rate.

Enhance product quality: Since the flexible force control robot can accurately control and adjust the force, it can avoid damage or deformation of parts caused by excessive force during the assembly process. This not only ensures the assembly quality of the product but also extends the service life of the product.

Improve the safety of the working environment: In some high-risk assembly environments (such as chemical industry, nuclear energy, etc.), the use of flexible robots can significantly reduce the safety risks of workers. Robots can replace manual assembly operations in dangerous environments, thereby protecting the life safety and physical health of workers.

Enhance corporate competitiveness: By introducing flexible robot technology, companies can improve production efficiency, reduce costs, and improve product quality. These will help enhance the market competitiveness of enterprises and promote the sustainable development of enterprises.

With the continuous advancement of technology and the gradual reduction of costs, flexible force control robots will be more widely used in the field of assembly. At the same time, with the continuous development and integrated application of technologies such as artificial intelligence and the Internet of Things, the intelligence level of flexible robots will be further improved. This will enable flexible force-controlled robots to play a more important role in future industrial production and promote the continuous development and innovation of the entire industry.
