The intelligent robotic arm is popular in the market because it can stabilize and improve welding quality, improve labor productivity, improve labor intensity of workers, work in harmful environments, and reduce the requirements for workers' operating skills. In practical applications, what should be paid attention to in writing programming? Today, Xiaobian will introduce it to you in detail.
1. Select a reasonable welding sequence for the robotic arm.
The welding sequence is formulated to reduce the welding deformation and the length of the welding torch walking path. The space transition of the welding torch requires a short, smooth and safe moving trajectory. Optimizing Welding Parameters In order to obtain the best welding parameters, working test pieces were made for welding test and process qualification.
2. Reasonable position of positioner, position of welding gun, position of welding gun relative to joint.
After the workpiece is fixed on the positioner, if the welding seam is not in the ideal position and angle, it is required to continuously adjust the positioner during programming, so that the welded seam reaches the horizontal position one by one according to the welding sequence, and at the same time, it is necessary to continuously adjust the position of each axis of the robot arm. , and reasonably determine the position, angle and wire extension of the welding torch relative to the joint. After the position of the workpiece is determined, it is difficult to observe the position of the welding torch relative to the joint through the programmer's eyes. This requires programmers to be good at summarizing and accumulating relevant experience of robotic arms.
3. Insert the gun cleaning procedure in time.
After writing a certain length of welding program, the gun cleaning program should be inserted in time, which can prevent welding spatter from clogging the welding nozzle and contact tip, ensure the cleaning of the welding gun, improve the life of the nozzle, ensure reliable arc ignition, and reduce welding spatter. Generally, the programming cannot be completed in one step. It is necessary to continuously check and modify the program during the welding process of the robot arm, and adjust the welding parameters and the posture of the welding torch to form a good program.
With the development of advanced manufacturing technology, it is an inevitable trend to realize the automation, flexibility and intelligence of welding product manufacturing. At present, the use of robotic welding has become the main symbol of the modernization of welding automation technology. The welding manipulator has received more and more attention due to its advantages of strong versatility and reliable operation.
