What are the key technologies of welding robot control system
The robot control system is the brain of the robot and the main factor determining the function and performance of the robot. The main task of industrial robot control technology is to control the position, posture, trajectory, operation sequence and action time of industrial robot in the workspace. It has the characteristics of simple programming, software menu operation, friendly man-machine interaction interface, online operation prompt and convenient use.
Spot welding robot
Welding robot has the characteristics of stable performance, large workspace, fast movement speed and strong load capacity. The welding quality is obviously superior to manual welding, which greatly improves the productivity of spot welding.
The spot welding robot is mainly used for welding the whole automobile, and the production process is completed by the major automobile engine manufacturers. International industrial robot enterprises, relying on their long-term cooperation with major automobile enterprises, provide various types of spot welding robot unit products to major automobile manufacturers and enter China in the form of welding robots and vehicle production lines, occupying a leading market position in this field.
With the development of the automobile industry, the welding clamp is required to be integrated in the welding production line, and its weight is becoming larger and larger. The 165kg spot welding robot is the most commonly used robot in automobile welding. In September 2008, the Robotics Research Institute developed the first 165 kg spot welding robot in China and successfully applied it to Chery Automobile Welding Workshop. In September 2009, the second robot with optimization and performance improvement was completed and successfully passed the acceptance. The overall technical indicators of the robot have reached the level of similar robots abroad.
Arc welding robot
Arc welding robot is mainly used in welding production of various automobile parts. In this field, international large-scale industrial robot manufacturers mainly provide unit products to complete equipment suppliers. The company is mainly engaged in the production of complete sets of arc welding robot equipment. According to the different needs of various projects, the company produces robot unit products in the complete sets of equipment by itself, and can also purchase and form various complete sets of arc welding robot equipment from large industrial robot enterprises. In this field, our company is both competitive and cooperative with large international industrial robot manufacturers.
Key technologies of arc welding robot include:
(1) Optimization and integration technology of arc welding robot system: the arc welding robot adopts AC servo drive technology, high-precision and rigid RV reducer and harmonic reducer, which has good low-speed stability and high-speed dynamic response, and can realize maintenance free function.
(2) Coordinated control technology: control the coordinated movement of multiple robots and positioner, which can not only maintain the relative posture of welding gun and workpiece to meet the requirements of welding process, but also avoid the collision between welding gun and workpiece.
(3) Precise seam tracking technology: Combining the advantages of offline working mode of laser sensor and visual sensor, laser sensor is used to achieve seam tracking in the welding process, improve the flexibility and adaptability of welding robot for complex workpieces, combine offline observation of visual sensor to obtain residual deviation of seam tracking, obtain compensation data based on deviation statistics and correct the robot's motion trajectory, The best welding quality can be obtained under various working conditions.
