The automatic assembly line company tells you that the basic parameters and performance indicators of the industrial robot loading and unloading manipulator mainly include workspace, degree of freedom, payload, motion accuracy, motion characteristics, dynamic characteristics, etc.

1. Workspace: refers to the set of positions that a specific part of the robot arm can reach under certain conditions. The character and size of the workspace reflect the size of the robot's working ability.

2. Degree of freedom of motion: refers to the number of variables required for the industrial robot manipulator to move in space, which is a parameter used to indicate the degree of flexibility of the robot's action. Generally, it is expressed by the number of independent motions moving along the axis and rotating around the axis.

3. Payload: refers to the weight of objects that may be carried or the force or torque that can be borne by the arm end when the robot is operating, which is used to indicate the load capacity of the operator.

4. Motion accuracy: The accuracy of robot manipulator system mainly involves position accuracy, repetitive position accuracy, trajectory accuracy, repetitive trajectory accuracy, etc.

5. Motion characteristics: speed and acceleration are the main indicators to indicate the motion characteristics of the robot. In the manual of industrial robots, a large stable speed for the main degree of freedom of motion is usually provided, but it is not enough to simply consider a large stable speed in practical applications, and attention should also be paid to its large allowable acceleration.

6. Dynamic characteristics: dynamic characteristics The dynamic parameters of the structure mainly include mass, inertia moment, stiffness, damping coefficient, natural frequency and vibration mode. If the stiffness is poor, the position accuracy and system natural frequency of the robot will decrease, which will lead to the dynamic instability of the system; The robot system integration thinks that it is beneficial to appropriately increase the flexibility for some operations (such as assembly operations). The ideal situation is to hope that the stiffness of the robot arm is adjustable.
