Intelligent robotic arms are popular in the market because they can stabilize and improve welding quality, increase labor productivity, improve labor intensity, work in harmful environments, and reduce the requirements for workers' operating skills.
So in the actual application of welding robots, what should be paid attention to in writing programming? Today I will introduce you in detail.
1. The robot arm selects a reasonable welding sequence.
The welding sequence is formulated to reduce the welding deformation and the length of the welding torch travel path. The space transition of the welding gun requires a short, smooth and safe movement trajectory. In order to optimize the welding parameters, in order to obtain the best welding parameters, work specimens are made for welding test and process qualification.
2. Reasonable position of the positioner, welding torch attitude, and the position of the welding torch relative to the joint.
After the workpiece is fixed on the positioner, if the welding seam is not the ideal position and angle, it is required to continuously adjust the positioner during programming, so that the welded seam reaches the horizontal position successively according to the welding sequence, and the mechanical arm must be constantly adjusted
For each axis position, reasonably determine the position and angle of the welding gun relative to the joint and the length of the welding wire. After the position of the workpiece is determined, it is difficult to observe the position of the welding gun relative to the joint through the eyes of the programmer. This requires programmers to be good at summing up and accumulating relevant experience of robotic arms.
3. Insert the gun cleaning program in time.
After writing a certain length of welding program, you should insert the gun cleaning program in time to prevent welding spatter from blocking the welding nozzle and contact tip, ensure the cleaning of the welding gun, increase the life of the nozzle, ensure reliable arc ignition, and reduce welding flying. It is generally not possible to compile a program in one step. It is necessary to continuously inspect and modify the program during the welding process of the robot arm, adjust the welding parameters and the welding torch posture, etc., to form a good program.
With the development of advanced manufacturing technology, it has become 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 strong versatility and reliable work.
