Welding robots mainly include two parts: robots and welding equipment. The robot consists of a robot body and a control cabinet (hardware and software). Welding equipment, such as arc welding and spot welding, consists of welding power supply (including its control system), wire feeder (arc welding), welding gun (clamp), and other components. For intelligent robots, there should also be sensing systems, such as laser or camera sensors and their control devices.
The welding robots produced in various countries around the world are basically joint robots, with the vast majority having 6 axes. Among them, axes 1, 2, and 3 can send end tools to different spatial positions, while axes 4, 5, and 6 address different requirements for tool posture. The mechanical structure of the welding robot body mainly has two forms: one is a parallelogram structure, and the other is a side mounted (pendulum) structure.
The main advantage of a side mounted (pendulum) structure is the wide range of motion of the upper and lower arms, allowing the robot's workspace to almost reach a sphere. Therefore, this type of robot can work upside down on a rack to save space and facilitate the flow of objects on the ground. However, this type of side mounted robot has a cantilever structure on the 2 and 3 axes, which reduces the stiffness of the robot. It is generally suitable for robots with small loads and is used for arc welding, cutting, or spraying.
The upper arm of a parallelogram robot is driven by a pull rod. The pull rod and lower arm form two sides of a parallelogram. Therefore, it is named. The early development of parallelogram robots had a relatively small workspace (limited to the front of the robot), making it difficult to work upside down. However, the new type of parallelogram robot (parallel robot) developed since the late 1980s has been able to expand the workspace to the top, back, and bottom of the robot, without the stiffness issue of measuring robots, thus gaining widespread attention.
