The difference between six-axis robots and four-axis robots

Joint robot, also known as joint arm robot or joint robot arm, is one of the most common forms of industrial robots in today's industrial field. Suitable for mechanical automation in many industrial fields, such as automatic assembly, painting, handling, welding and other work.

The axis of the so-called industrial robot can be explained by the professional term "freedom". It is reasonable to assume that as the number of axes of the robot increases, the robot will have higher flexibility. Four-axis SCARA robot (hereinafter referred to as four-axis robot) and six-axis tube

Node robots (hereinafter referred to as six-axis robots), where four-axis robots are specifically designed for high-speed take-and-place operations, while six-axis robots provide greater flexibility in production motion.

The axis is related to the Qadir coordinate system. A three-axis robot, also known as a Cartesian or Cartesian robot, has three axes that allow the robot to move in the direction of three axes. The six axes of the six-axis robot are the X, Y and Z axes in the Cartesian coordinate system, and the U, V and W axes rotating around the X, Y and Z axes.

Four-axis robot

The four-axis is designed for high-speed take-and-place operations, so the six-axis with more than two axes provides greater flexibility. In the hands of small assembly machines, "four-axis manipulator" refers to "selectively assembled joint robot arm", that is, the arm part of the four-axis manipulator can move freely in a geometric plane. The first two joints of the four-axis manipulator can be freely rotated left and right in the horizontal plane, and the third joint consists of a metal rod called a quill and a gripper. The metal rod can move up and down in the vertical plane or rotate around its vertical axis, but cannot tilt.

This unique design gives four-axis manipulators strong rigidity, which makes them competent for high-speed and highly repeatable work. In packaging applications, four-axis manipulators excel at high-speed pick-and-place and other material handling tasks.

Four-axis robot

Six-axis robot

A six-axis robot has two more joints than a four-axis robot and therefore has more "freedom of action." The first joint of the six-axis robot can rotate freely in the horizontal plane like the four-axis robot, and the last two joints can move in the vertical plane. In addition, the six-axis robot has one "arm" and two "wrist" joints, giving it human-like arm and wrist capabilities.

The greater number of joints in six-axis robots means they can pick up parts facing any direction on the horizontal plane and place them into packaged products at a special Angle. Perform many operations that can only be done by skilled workers. And it can save manpower costs, and it is a good choice for companies that have just been founded.

Six-axis robot

Four-axis, six-axis robots can also be collectively referred to as "automation", automation technology can not only liberate people from heavy physical labor, part of the mental work and poor, dangerous working environment, but also expand human organ functions, greatly improve labor productivity, enhance human understanding of the world and the ability to transform the world.

The integration and application of robot technology in the packaging production line is not as complex, dangerous and costly as some people think, but it is very simple and safe, and may also gain economic advantages.
