Embodiment Construction

[0018] combine figure 1 , Driven by stepper motor and servo motor, controlled by 89C51 single-chip microcomputer, arm expansion, rotation, wrist lifting, and claw opening and closing are controlled by stepper motor open-loop; wrist rotation and claw rotation are controlled by DC motor closed-loop. Among them, the stepper motor is driven by a single-voltage constant-current source, and the control pulse signal is directly sent out by the single-chip microcomputer. The closed-loop control of the wrist is realized by adding a photoelectric code disc to a DC torque motor, and the display part adopts an LCD liquid crystal display module. Structural design of the hand gripper. In this system, the grasping weight is 5N, and the finger opening and closing is 5.10. We decided to choose the chute lever fulcrum swivel hand. This structure can change the size of the grip force and the opening and closing angle between the fingers through the angle or the length of the bars between the ...

Abstract

Provided is a multi-degree-of-freedom industrial robot which can be applied to teaching demonstration. The industrial robot is low in price, superior in performance and simple in structure, a manipulator of the industrial robot has multiple degrees of freedom, and students can perform programming themselves to change the motion state of the manipulator. According to the industrial robot, an 89C51 single chip microcomputer is used as a controller, a direct-current motor is driven by a PWM power amplifier, and the control mode is simple and easy to learn. The manipulator adopts a chute lever design, and the frictional resistance in the control process is greatly reduced. A stepping motor is adopted to drive a screw-nut transmission mechanism to produce linear motion in arm extension and retraction. When an arm and wrist mechanism is driven by a nut to extend and retract, transmission is performed by a common screw. Therefore, the multi-degree-of-freedom teaching robot is light in weight and compact in structure.

Description

technical field [0001] The present invention is a multi-degree-of-freedom industrial robot that can be applied to teaching and demonstration. Specifically, through the control of 51 single-chip microcomputers, the closed-loop DC motor control system with the PWM controller as the core completes the control of the entire industrial robot to realize the teaching and demonstration function. . Background technique [0002] The use of robots will bring us great convenience. The main difference between robots and other automation devices is that the functions and tasks of robots are easy to modify or change, and only need to change the software. At the same time, robots are more complicated than general automation equipment. More software and hardware knowledge is needed, so once a large number of robots are used, special training is required for high-level and technical personnel who use robots. This undoubtedly puts forward new requirements for education and training. Most robot...
