First, industrial robots are divided into four types according to the movement of the arm:
1. The right-angled coordinate arm can move along three orthogonal coordinates;
2. The cylindrical coordinate type arm can be used for lifting, turning and telescopic movement;
3. The spherical coordinate type of the arm can be rotated, pitched and telescoped;
4. The articulated arm has multiple rotating joints.
Second, the control function of the industrial robot according to the movement of the actuator can be divided into points and continuous track type.
1. The point type only controls the accurate positioning of the actuator from one point to another, and is suitable for machine loading and unloading, spot welding and general handling, loading and unloading operations;
2, continuous track type can control the actuator to move according to a given trajectory, suitable for continuous welding and painting operations.
Third, the industrial robot is divided into two types: programming input type and teaching input type according to the program input mode:
1. The programming input type is to transfer the programmed program files on the computer to the robot control cabinet through RS232 serial port or Ethernet communication.
2. There are two teaching methods for teaching input type:
One is that the operator uses a manual controller (teaching operation box) to transmit the command signal to the drive system, so that the actuator can be operated in accordance with the required sequence of motions and motion trajectories;
The other is that the operator directly leads the actuator and performs it in the required sequence of actions and motion trajectories. At the same time of the teaching process, the information of the working program is automatically stored in the program memory. When the robot automatically works, the control system detects the corresponding information from the program memory, and transmits the command signal to the driving mechanism, so that the executing mechanism reproduces the teaching. Various actions. The industrial robot that teaches the input program is called a teaching and reproducing industrial robot.
Fourth, intelligent industrial robot
Industrial robots with tactile, force or simple vision can work in more complex environments; if they have recognition functions or further increase adaptive, self-learning functions, they become intelligent industrial robots. It can adapt to the environment according to the "macro" selection or self-programming given by people, and automatically complete more complicated work.
