There are many ways to classify industrial robots, which can be classified according to mechanical structure, operator coordinate form and program input method.
A Classification by Mechanical Structure
1, tandem robots: the motion of one axis will change the coordinate origin of another axis. For example, six-jointed robots.
2, parallel robots: the movement of one axis does not affect the coordinate origin of the other axis, such as the spider robot.
Two according to the operator coordinate form classification
1, cylindrical coordinate robot arm can be lifted and lowered, rotary and telescopic movements;
2, ball coordinate robot arm can rotate, pitch and telescopic;
3, multi-jointed robots arm has more than one rotating joints.
4, plane joint type robot axis parallel to each other, realize in-plane positioning and orientation;
5, right-angle coordinate type robot arm can move along the three right-angle coordinates;
Three according to the program input method classification
1, programming input type robot: programming input type is the computer will have been programmed job program file. Programming input type is the computer has been programmed operating program files, through the RS232 serial port or Ethernet and other communication methods to the robot control cabinet.
2, teaching input type robot: teaching input type teaching method has two kinds, one is by the operator with a manual controller (teaching manipulation box), the command signal to the drive system, so that the actuator in accordance with the required sequence of action and the trajectory of the exercise once. The other is by the operator directly lead the actuator, according to the required sequence of action and movement trajectory drill again. In the process of teaching at the same time, the work program information that is automatically stored in the program memory in the automatic work of the robot, the control system from the program memory to detect the corresponding information, the command signal to the drive mechanism, so that the actuator to reproduce a variety of actions taught.
