Six-axis industrial robots are 6-joint industrial robots commonly used in actual production. They are also called six-axis robotic arms, six-joint robotic hands, six-axis robotic arms, robotic arms, etc. Industrial robots generally refer to four-axis, five-axis, and six-axis robotic hands. The joint structure of each robot will be different. Below, we will explain which six axes of a six-axis robot are and what their functions are.
The first axis: the main body rotation axis, which is the part that connects to the base. It is the axis that bears the largest load of the industrial robot. It can rotate left and right, similar to the movement of a millstone. It bears the weight of the entire robot and the large horizontal swing of the robot.
The second axis: The main arm's forward and backward swing axis is the core connection point of the robot components, serving as a link between the upper and lower parts, and is an important axis for controlling the robot's forward and backward swing and extension.
The third axis: The third axis controls the robot's back-and-forth swing. The third axis has a similar motion function to the second axis, which also controls the robot's loading and unloading swing function. The motion of the third axis is relatively small, but this is also the basis for the arm span of the six-axis robot.
The fourth axis is the cylindrical shaft on an industrial robot. It can rotate freely. It's essentially the rotation of a cylinder, but with an additional cable restricting its movement. The fourth axis controls the 180° free rotation of the upper arm, which is analogous to a human forearm.
Fifth axis: The fifth axis is very important. After you have roughly adjusted the position, you need to accurately position it on the product, which is where the fifth axis comes in. This position is similar to the wrist joint in the human arm. It can move up and down slightly and is used to flip the product or a fixed tool after it is gripped.
The sixth axis: the end rotation axis, is a joint used for fine-tuning the position at the rear. After you have positioned the fifth axis on the product, if you need to make some minor changes, you will need to use the sixth axis. The sixth axis is equivalent to a turntable that can rotate 360° horizontally. It can position the product more precisely.
