Welding robots mainly consist of two parts: the robot itself and the control cabinet (hardware and software). The welding equipment, such as for arc welding and spot welding, is composed of the welding power source (including its control system), wire feeder (for arc welding), welding clamp, etc. Intelligent robots should also have a sensing system, 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 onto the workbench surface using fixtures, making the system quite simple. However, in actual production, more workpieces need to be repositioned during welding to ensure the weld seam is in an optimal position (orientation). In such cases, the manipulator and robot can either move separately—the manipulator repositions first, followed by the robot welding—or they can move simultaneously—the manipulator repositions 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.ClampRequirements for posture. In fact, at this point, the axis of the transposer has become a part of the robot. This welding robot system can have up to 7-20 axes, or more.
The control cabinet for robots can coordinate the movement of 12 axes for two robots working together. One is a welding robot, and the other is a handling robot used as a positioner.
