Key point: In the field of industrial automation, industrial robots have become an indispensable and important tool. According to their design and application scenarios, industrial robots can have different numbers of degrees of freedom (DOF), also known as "axes". These robots have achieved diversified applications from simple handling to complex assembly through different axis configurations. According to their different structures and degrees of freedom, robots can be divided into various types, among which the most common are 3 axis, 4 axis, 5 axis, 6 axis, and robots with a 7 axis.

In the field of industrial automation, industrial robots have become an indispensable and important tool. According to their design and application scenarios, industrial robots can have different numbers of degrees of freedom (DOF), also known as "axes". These robots have achieved diversified applications from simple handling to complex assembly through different axis configurations. According to their different structures and degrees of freedom, robots can be divided into various types, among which the most common are three-axis, four axis, five axis, six axis, and robots with a seventh axis. This article will delve into the differences between the seventh axis of robots and the 3, 4, 5, and 6 axis robots, helping readers better understand the characteristics and application scenarios of these robots.
1、 The definition and significance of the number of axes in industrial robots
The number of axes of industrial robots is usually explained using the professional term 'degrees of freedom'. Degree of freedom refers to the number of dimensions in which a robot can move independently. For example, a three-axis robot has three degrees of freedom and can move freely along the X, Y, and Z axes, but cannot tilt or rotate. As the number of axes increases, the flexibility of the robot also increases, enabling it to complete more complex tasks.
2、 Characteristics of Three, Four, Five, and Six Axis Robots
3 Axis Robot (Cartesian or Cartesian robot)
Features: The three-axis robot moves along the X, Y, and Z linear axes, suitable for simple handling work.
Application: Commonly used for simple automated operations such as material handling and palletizing.
4 Axis Robots (such as SCARA robots)
Features: In addition to the movement of the X, Y, and Z axes, an independent fourth axis has been added, which is usually used for high-speed picking and placing operations.
Application: Widely used in industries such as electronics and packaging, skilled in high-speed and high-precision material handling and assembly.
5 Axis Robot
Features: Rotation is achieved through the X, Y, and Z spatial axes, while relying on the axis on the base to achieve the turning action, as well as the axis for flexible hand rotation, increasing flexibility.
Application: Suitable for complex assembly tasks that require multi-directional rotation, such as component installation in automotive manufacturing.
6 Axis Robot
Features: The six axis robot can pass through the X, Y, and Z axes, and each axis can rotate independently, with extremely high flexibility.
Application: Widely used in fields such as electronics, automotive, aerospace, etc., capable of completing complex tasks such as assembly, welding, and spraying.
3、 Characteristics and Applications of the 7 Axis of Robots
Definition: The 7 axis of a robot is not a traditional part of the robot body, but refers to an additional device installed on the walking axis guide rail for connecting and moving industrial robots. This mechanism allows robots to move from one workstation to another, achieving multi workstation operations.
characteristic:
Multi degree of freedom motion: The seventh axis provides additional degrees of freedom, allowing the robot to move flexibly over a larger spatial range.
High precision and reliability: Adopting a fully servo power system, it achieves fast speed and high precision, and has dust-proof and anti fouling design, suitable for harsh environments.
Long stroke application: Suitable for various long stroke operations such as loading and unloading, welding, assembly, and spraying of machine tool workpieces.
Application:
Production line automation: On the automated production line, the seventh axis robot can efficiently move between multiple workstations to complete different processes.
Space constrained environment: In narrow or complex working environments, the seventh axis robot can flexibly avoid obstacles and complete tasks that traditional robots find difficult to accomplish.
Summary
There are significant differences in structure, function, and application scenarios between the seventh axis robot and the third, fourth, fifth, and sixth axis robots. 3, 4, 5, and 6 axis robots mainly improve flexibility by increasing the number of axes and are suitable for industrial tasks of different complexities; The seventh axis serves as an additional device for connecting and moving industrial robots, expanding their working range and flexibility. With the continuous development of industrial automation technology, these robots will play an important role in more fields, driving the manufacturing industry towards intelligence and efficiency.
