Preface: Six-joint robots, also known as "six-degree-of-freedom robots," are widely used in large-scale industrial production. Their basic structure is a spatial six-bar open-chain structure composed of six rotating axes. Composed of seven parts and six joints, they possess six degrees of freedom, each a rotary joint, and feature an open structure with excellent interaction with the external environment. They are suitable for automated mechanical operations in many industrial fields, such as automated assembly, painting, material handling, and welding.
A six-joint robot consists of a body, arm, wrist, and hand. The vast majority of six-joint robots are based on a rotating base, which directly connects to, supports, and transmits the robot's main motion mechanisms.
Six-joint robots are typically used in production lines for automobiles or other large equipment. They require a robot with a relatively large range of motion that can efficiently carry out production, which is why six-joint robots usually use a rotary base type body.
Therefore, the most outstanding feature of a six-joint robot is that it is different from other planar robots. A six-joint robot can work at multiple angles, especially in multi-angle assembly situations such as automobile assembly. Screws in different places need to be tightened at different angles, so the horizontal assembly method used before is far from enough.
The six-joint robot, paired with a smart screwdriver, can achieve precise screw tightening from multiple angles, eliminating the need for manual screwdriver handling. Once the torque is set, the six-joint intelligent tightening device can automatically tighten screws precisely and accurately at every angle. It also features a built-in feedback function, allowing inspectors to check the tightening status at any time. In case of an emergency, it will sound an alarm and immediately stop working, providing an excellent tightening solution for many situations requiring multi-directional tightening.
