Summary: | Assembly is an important part of the production of industrial robots. When the load is large, adjusting the robot's position and the contact force is difficult to control. This paper proposes a flexible assembly method for large-scale heavy-load machines based on a force sensor. First, the robotic arm moves the load to different positions to collect the force sensor information and calculates the parameters of robot base installation inclination, force sensor zero error, workpiece gravity, and center of gravity position. Then, real-time gravity compensation is realized according to the robot's position and posture. Mobile assembly is carried out according to the contact force value and all the holes on the cabin are plated into the pins. Experiments show that this method can improve the assembly accuracy of large-scale heavy-load robots and realize flexible robot assembly. |
