Welding robots primarily consist of two parts: the robot itself and the control cabinet (hardware and software). Welding equipment, such as arc welding and spot welding, is composed of welding power sources (including their control systems), wire feeders (for arc welding), welding clamps, and more. For intelligent robots, a sensor system is also required, such as laser or camera sensors and their control devices.
If the workpiece does not require any positioning changes throughout the welding process, it can be clamped and positioned on the worktable. This system is as simple as it gets. However, in actual production, more workpieces need to be repositioned during welding to ensure the weld seam is in an optimal position (attitude). In such cases, the manipulator and robot can either move separately, with the manipulator positioning first and then the robot welding; or they can move simultaneously, with the manipulator repositioning while the robot welds, which is commonly referred to as coordinated movement between the manipulator and the robot. At this point, the combined movement of the manipulator and the robot allows for welding...ClampIn relation to the workpiece movement, it can meet both the welding path and the welding speed requirements.ClampPosition requirements. In fact, at this point, the axis of the transposer has become part of the robot. This welding robot system can have up to 7-20 axes, or even more.
The control cabinet for robots can coordinate the movement of 12 axes between two robots. One is a welding robot, while the other is a handling robot used as a manipulator.
