Automatic assembly line manufacturers believe that industrial robots have become a part of our lives. NC machine tool loading and unloading manipulator and NC machine tool robot are common robots in the NC machine industry. Industrial robot is a kind of opto mechatronics equipment which is composed of manipulator (mechanical body), controller, servo drive system and sensor device, which can simulate human operation, automatic control, repeatable programming and complete various operations in three-dimensional space.

There are many classification methods for industrial robot manipulators, which can be classified according to mechanical structure, operator coordinate form and program input mode.

1、 According to the mechanical structure, the industrial robot manipulator can be divided into: serial robot and parallel robot;

2、 Industrial robot manipulators are divided into:

1. The arm of the cylindrical coordinate industrial robot can be used for lifting, rotating and telescoping;

2. The arm of the spherical coordinate industrial robot can rotate, pitch and stretch;

3. The arm of the multi joint industrial robot has multiple rotation joints;

4. The axes of the planar articulated industrial robot are parallel to each other to achieve in-plane positioning and orientation;

5. The arm of the rectangular coordinate industrial robot can move along three rectangular coordinates;

3、 Industrial robot manipulators are divided into:

1. Programming input type robot: programming input type is to transmit the operation program file programmed on the computer to the robot control cabinet through RS232 serial port or Ethernet and other communication methods.

2. Teaching input robot: There are two teaching methods of teaching input type. One is that the operator uses a manual controller (teaching control box) to transmit the command signal to the drive system, so that the actuator can perform once according to the required action sequence and motion track. The robot system integration tells you that the other way is to let the operator directly lead the actuator and perform it once according to the required action sequence and motion track.
