How to set the drag trajectory of a six axis welding robot? Six axis welding robots play an important role in modern manufacturing, and their precise operation and efficient work capabilities have brought revolutionary changes to welding processes. For a six axis welding robot, setting the drag trajectory is one of the key steps to achieve precise welding.
When setting the drag and drop trajectory, the first step is to program the robot through demonstration mode. The operator manually guides the robot along the predetermined welding path using a teaching pendant, while recording the coordinates, velocity, acceleration, and other information of each step. During this process, the robot will provide real-time feedback on its position information to ensure the accuracy of the path.
After completing the demonstration, the robot will generate the corresponding welding program based on the recorded trajectory information. This program includes the complete path from the starting point to the endpoint, as well as the pose, velocity, and acceleration requirements for each point along the way. To further improve welding accuracy, several intermediate points can be added to the trajectory, and the pose of these points can be converted into the angle values of each joint of the robot through inverse kinematics.
In the trajectory planning stage, joint space method or Cartesian space method are often used. The joint space method focuses on controlling the angle changes of each joint of the robot, while the Cartesian space method pays more attention to the position and posture of the robot's end effector in three-dimensional space. By selecting appropriate interpolation algorithms, such as cubic polynomial interpolation or parabolic transition linear interpolation, it is possible to ensure smooth motion of the robot along the predetermined trajectory, avoiding abrupt changes and vibrations.
Finally, in the automatic welding process, it is necessary to monitor the welding status in real time and adjust welding parameters such as current, voltage, and speed as needed to achieve good welding results. Through scientifically reasonable drag trajectory settings and precise welding control, the six axis welding robot can efficiently and stably complete various complex welding tasks, providing strong support for the automation production of the manufacturing industry.
