The axis of the so-called industrial robot can be explained by the professional term degree of freedom. If the robot has three degrees of freedom, it can move freely along the x, y, and z axes, but it cannot tilt or rotate.
In the production of industrial robots, it is generally necessary to be equipped with peripheral equipment other than its own performance characteristics, such as a rotary table for rotating workpieces, and a mobile table for moving workpieces. The motion and position control of these peripheral devices need to cooperate with industrial robots and require corresponding precision.
When the number of axes of the robot increases, it means higher flexibility for the robot. So how many axes should an industrial robot have?
At present, the number of axes of industrial robots on the market ranges from one to seven. There are not only single-axis robots, but also seven-axis robots.
Single-axis and two-axis robots are also called linear modules, electric slides, etc. in China. They are mechanical structures that can provide linear motion. At the same time, more complex tasks can be completed through combination. The name also explains from another It can complete the specified work in a modular manner, and at the same time it shows that the single-axis robot has been developed very maturely.
A three-axis robot is also called a Cartesian or Cartesian robot. Its three axes allow the robot to move along three axes. This robot is generally used for simple handling tasks.
The four-axis robot can rotate along the x, y, and z axes. Unlike the three-axis robot, it has a fourth axis that moves independently
The five-axis robot is the configuration of many industrial robots. These robots can rotate through the three space circles of x, y, and z. its flexibility.
The six-axis robot can pass through the x, y, and z axes, and each axis can rotate independently. The biggest difference from the five-axis robot is that there is one more axis that can rotate freely. The representative of the six-axis robot is the Universal Robots. Through the blue cover on the robot, you can clearly calculate the number of axes of the robot.
Seven-axis robot, also known as redundant robot, generally seven-axis is the external axis of the robot, and the external axis is also called the robot ground rail. Compared with the six-axis robot, the extra axis allows the robot to avoid certain specific targets, facilitate the end effector to reach a specific position, and can be more flexible to adapt to certain special working environments.
