Problems solved by technology
However, the encoder motor control scheme has the following disadvantages: 1. Mechanical vibration can easily cause displacement or offset of the photoelectric transmitter tube or receiver tube, resulting in the inability of the receiver tube to receive signals reliably, resulting in system instability or malfunction
2. Due to external electromagnetic interference, the output waveform of the photoelectric detection device is distorted, resulting in system instability or malfunction

The invention relates to the technical field of mechanical control, in particular to a rotating control system of a joint robot and a control method thereof. The rotating control system of the joint robot comprises a motion programming controller, a motor control circuit and a motor which are connected with one another in sequence through electrical signals; an output shaft of the motor is connected with a rotating resistor through a drive shaft, the resistance value of the rotating resistor is adjusted through rotation of the drive shaft, and adjustment of the output voltage value is achieved; the motion programming controller is used for comparing the output voltage value with a preset voltage value, and the working state of the motor is adjusted through the result of the voltage comparison. According to the rotating control system of the joint robot and the control method thereof, misoperation caused by mechanical vibration or external electromagnet interference is avoided, the stability is high, the structure is simple, and the cost-performance ratio is high.
Description
technical field [0001] The invention relates to the technical field of mechanical control, in particular to a rotation control system of a joint robot and a control method thereof. Background technique [0002] Joint robot, also known as joint arm robot or joint robot arm, is one of the most common industrial robots in the industrial field today. In the existing industrial production process, joint robots are often used for auxiliary production; in the existing joint In robots, motion programming controllers, harmonic reducers, servo motors, servo motor drivers and position encoders are generally used to control the joint rotation of joint robots; and position encoders generally use photoelectric code discs, which are composed of photoelectric emission and photoelectric Receive, read, and form 4 groups of sine wave pulse signals with a phase difference of 90 degrees such as A, B, C, and D, and feed back the sine wave pulse signals to the motion programming controller, and th...
