Application of robot vision positioning in automobile manufacturing industry

In recent years, with the advancement of technology, the application field of industrial robots is expanding. Compared with workers whose labor costs are rising, companies prefer to use hard-working, one-time investment industrial robots to perform standardized operations, making robot technology The industry is bearing fruit and is widely used. According to the data, at present, regardless of domestic or global, the industry with the most applications is the automobile manufacturing industry.

Statistics show that in developed countries, robots in the automotive industry account for more than 53% of total robot ownership. In China, 50% of industrial robots are used in the automotive industry, of which more than 50% are welding robots. According to statistics, the world's major automobile manufacturers have an annual output of more than 10 robots per 10,000 cars. With the continuous development and improvement of robot technology, industrial robots will greatly promote the development of automobile manufacturing. And China is moving from a manufacturing country to a manufacturing country. It needs to improve processing methods, improve product quality, and increase enterprise competitiveness, all of which indicate that the development of robots is promising.

The following is a typical application case: China National Heavy Duty Truck Group Co., Ltd., before the introduction of robots, a worker can only look after two machine tools. After the introduction of industrial robots, one robot can automatically control 5-10 machining centers. From 2005 to 2011, the annual output of China National Heavy Duty Trucks increased from more than 40,000 to 150,000, while the number of fixed employees increased by only about 10%. For the introduction of robots. In addition, in 2008, Sinotruk introduced industrial robots when building a new workshop, and built a fully automatic stamping machine. The steel plate was sent to the stamping machine by a mechanical arm, which not only stabilized the product quality but also replaced manual labor to avoid work-related injuries. happened.

However, the above-mentioned robots all exist as a rigid actuator, that is, they can only be continuously repeated according to a preset path and action. For current manufacturing tasks of the enterprise, which require more and more complicated production processes, it starts The effect of this is becoming increasingly limited. How to improve the intelligence and flexibility of robots? Here we may wish to learn from the current fiery intelligent manufacturing and artificial intelligence concepts. If we install a visual sensor on the robot and determine the next processing procedure based on the judgment after determining the acquired image, then the robot will undoubtedly start from the original "hand The execution function of "" has evolved to increase the observation and judgment functions of "eye" and "brain", thereby improving its intelligence and greatly expanding its application scenarios. For example, the robot combines positioning functions, measurement functions, and defect detection functions, so that the robot can adapt to more complex production tasks.

Let's look at the typical application of the robot in the automotive manufacturing industry from the direction of visual positioning of the robot.

The above picture shows the process of auto parts assembly by robots using automated equipment. The key technology used in this is robot vision positioning. In actual production, because the workpiece has a certain angle, the angle information cannot be accurately positioned by mechanical means. If a traditional robotic actuator is used, the accuracy of the angle cannot be guaranteed during gripping, and the assembly task cannot be completed. At this time, we use dual cameras to determine the position and angle of the incoming material from the two directions as novelty, determine the assembly position, and calculate the coordinate and angle information to the robot to complete the task of guiding the robot to accurately grasp and complete the assembly. .

This is just a simple example of robot vision positioning. Similar applications abound in this industry and are showing a significant increase. Among the vision positioning solutions used in the country, there are many manufacturers that can be matched. Weishi is a vision company that has been engaged in independent research and development for nearly 20 years. It can provide a comprehensive range of products, from industrial cameras and lenses to including vision positioning guidance functions. All intelligent vision software are available, and have been verified by a large number of long-term field tests. The cost performance and stability are relatively high.
