What are the classification methods of industrial robots? Introduction to the types of industrial robots
Introduction: At present, robots are divided into two categories internationally based on application environment: industrial robots in manufacturing environment and service and humanoid robots in non manufacturing environment. According to the application environment, robot experts in China also divide robots into two categories, namely industrial robots and special robots. This is consistent with the international classification.
Industrial robots refer to multi joint manipulators or multi degree of freedom robots facing the industrial field. Special robots are all kinds of advanced robots except industrial robots, which are used in non manufacturing industries and serve human beings, including service robots, underwater robots, entertainment robots, military robots, agricultural robots, etc. Among special robots, some branches are developing rapidly, and there is a trend of becoming independent systems, such as service robots, underwater robots, military robots, micro-manipulation robots, etc.
1. Industrial robots are divided into four types according to the motion form of the arm.
The arm of rectangular coordinate type can move along three rectangular coordinates; The cylindrical coordinate type arm can be used for lifting, turning and telescoping; The arm of spherical coordinate type can rotate, pitch and stretch; The articulated arm has a plurality of rotation joints.
2. Industrial robots can also be divided into point type and continuous track type according to the control function of the motion of the actuator.
The point position type only controls the accurate positioning of the actuator from one point to another, and is suitable for loading and unloading of machine tools, spot welding, general handling, loading and unloading, etc; The continuous track type can control the actuator to move according to the given track, which is suitable for continuous welding, painting and other operations.
3. Industrial robots can be divided into two types according to program input mode: programming input type and teaching input type.
The programming input type is to transmit the programmed operation program file on the computer to the robot control cabinet through RS-232 serial port or Ethernet and other communication methods.
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 other is that the operator directly leads the actuator, and drills it once according to the required action sequence and motion track.
At the same time of the teaching process, the information of the working program is automatically stored in the program memory. When the robot works automatically, the control system picks out the corresponding information from the program memory and transmits the command signal to the drive mechanism, so that the actuator can reproduce various actions of the teaching. The industrial robot of teaching input program is called teaching reappearance industrial robot.
