ABB robots, with their efficient, precise and reliable motion capabilities, are widely used in the industrial sector. The number of axes of ABB robots and their functions are described in detail as follows:
First, Number of axes of ABB robot
ABB robots, such as the IRB 140, are six-axis multi-purpose industrial robots. This means that they have six articulated axes, which are labeled axis 1, axis 2, axis 3, axis 4, axis 5, and axis 6 (different brands or models of robots may have axes labeled differently, but with similar functions).
Second, the role of each axis
Axes 1 to 3: These axes are usually responsible for the main movements of the robot arm, including such actions as pitching, deflection, and rotation. They work together to enable the robotic arm to move flexibly in three-dimensional space to reach specified positions and attitudes.
Axes 4 to 6: These axes are mainly responsible for the motion of the robot wrist. They enable movements such as wrist rotation, swinging and turning, ensuring that the robot can accurately grasp, place or operate various tools and workpieces.
By working together with these six axes, ABB robots are able to complete a variety of complex work tasks, such as assembly, welding, spraying, handling and so on.
Third, the application of external axes
In addition to the six internal axes mentioned above, ABB robots can also be integrated with external axes to further extend their range of motion and flexibility. The external shaft usually includes a slide rail (ground rail), a turnover table (positioner) and additional servo equipment.
1.Slide rail: The robot is mounted on the slide rail, and the long-distance movement of the joint robot is realized by controlling the ground slide through the external shaft function. This enables large-scale, multi-station work, such as the taking and placing of multiple machine tools by one arm in the machine tool industry.
2.Turning table: The function of the external shaft controls the turning to a specific Angle, which is more conducive to the processing of a certain face of the workpiece by the arm. This is mainly used in welding, cutting, spraying and heat treatment.
3.Additional servo equipment: Use the function of the external shaft to control more kinds of external servo equipment such as servo welding gun, so as to achieve more functions of the arm. For example, in the stamping industry, a straight axis is added to the end of the joint robot, and the rapid movement of the straight axis is controlled by the external axis, which greatly improves the efficiency of the punch taking and placing.
In summary, the ABB robot's six internal and external axes work together to enable it to complete a variety of complex work tasks. The design and innovation of these axes provide greater room for improvement in robot performance and functionality.
