Technical Field

[0001] This utility model relates to the field of servo device testing technology, specifically a novel servo device testing device. Background Technology

[0002] Servo devices, as important driving structures in the field of automation, are used in various automated production lines. Electrically fed servo devices typically include a servo driver and a servo motor. The servo driver receives external signals and controls the position, speed, and torque of the servo motor. Different electrically fed servo devices have varying power consumption during use, making energy efficiency testing an important indicator of their quality. However, they still have some drawbacks, such as the inability to constantly monitor and adjust motor speed, and issues with the stability and accuracy of system signal transmission. To address these problems, this application proposes a novel servo device testing device. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of servo equipment testing device to solve the problems mentioned in the background art, such as the fact that most of the energy-saving tests of servo equipment are carried out manually, and that the servo motor must be stopped before the adjustment can be made, which greatly reduces the testing speed.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel servo equipment testing device, the testing device comprising a servo motor, a photoelectric encoder, a turntable antenna, a detector, and a servo controller, wherein a photoelectric encoder is fixedly connected to the outer surface of the rear end of the servo motor, a cable is fixedly connected to the outer surface of the upper end of the photoelectric encoder, a cable connector is fixedly connected to the outer surface of one end of the cable connector, a cable connector is detachably connected to the outer surface of one end of the cable connector, and a cable is fixedly connected to the outer surface of one end of the cable connector.

[0005] Preferably, the outer surface of the rear end of the servo motor is connected to a connecting shaft, and a grating disk is fixedly connected to the outer wall of the connecting shaft.

[0006] Preferably, a photoelectric sensor is fixedly connected to the inner surface of the photoelectric encoder, and the photoelectric sensor is located at the rear end of the grating disk.

[0007] Preferably, a turntable antenna is fixedly connected to the outer surface of one end of the second cable, a third cable is fixedly connected to the outer surface of one end of the turntable antenna, and a rotary transformer and a motor driver are provided on the inner surface of the turntable antenna.

[0009] Preferably, a detector is fixedly connected to the outer surface of one end of the cable three, and a digital-to-analog converter and an analog-to-digital converter are provided on the inner surface of the detector.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention utilizes an analog-to-digital converter (ADC) to convert analog signals from a position photoelectric encoder into digital signals for servo motor control. This digital signal is then processed by a microcontroller or digital controller for precise position control. This conversion helps achieve higher position accuracy and reduces position errors. Simultaneously, in speed control, the ADC converts tachogenerator signals into digital values, enabling the control system to monitor and adjust motor speed in real time, thus ensuring stable motor operation. Furthermore, it guarantees the stability and accuracy of system signal transmission, reducing malfunctions caused by signal distortion or errors, thereby improving system reliability.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a novel servo equipment testing device, including a servo motor 1, a photoelectric encoder 2, a turntable antenna 7, a detector 9, and a servo controller 11. The photoelectric encoder 2 is fixedly connected to the outer surface of the rear end of the servo motor 1. The upper outer surface of the photoelectric encoder 2 is fixedly connected to a cable 3. The outer surface of one end of the cable 3 is fixedly connected to a cable connector 4. The outer surface of one end of the cable connector 4 is detachably connected to a cable connector 5. The outer surface of one end of the cable connector 5 is fixedly connected to a cable 6.

[0019] In this embodiment, as Figures 2-4 As shown, a connecting shaft 12 is connected to the outer surface of the rear end of the servo motor 1. A grating disk 13 is fixedly connected to the outer wall of the connecting shaft 12. The grating disk 13 can convert mechanical motion into light signals, provide high-precision position feedback, and realize direction detection. A photoelectric sensor 14 is fixedly connected to the inner surface of the photoelectric encoder 2, and the photoelectric sensor 14 is located at the rear end of the grating disk 13. The photoelectric sensor 14 can accurately detect the presence and position of an object by emitting light and receiving reflected or blocked light signals. A turntable antenna 7 is fixedly connected to the outer surface of one end of the cable 2 6, and a cable 3 8 is fixedly connected to the outer surface of the turntable antenna 7. A rotary transformer 17 and a motor driver 18 are provided on the inner surface of the turntable antenna 7. The turntable antenna 7 ensures wireless communication. The stability and coverage range enable comprehensive signal coverage, improve signal reception and transmission efficiency, and enhance the flexibility and reliability of the communication system. A connecting cable 10 is fixedly connected to the outer surface of the rear end of the detector 9. A servo controller 11 is detachably connected to the outer surface of one end of the connecting cable 10. The servo controller 11 can control the servo motor 1 in three ways: position, speed, and torque, ensuring that the servo motor 1 can accurately execute operation commands. A detector 9 is fixedly connected to the outer surface of one end of the cable 8. A digital-to-analog converter 15 and an analog-to-digital converter 16 are provided on the inner surface of the detector 9. The analog-to-digital converter 16 can convert the analog signal from the position photoelectric encoder 2 into a digital signal in the control of the servo motor 1, so that the microcontroller or digital controller can process and accurately control the position.

[0020] Working principle:

[0021] A novel servo device detection device, during detection, first uses the coordinated action of the grating disk 13, LED light source, marking disk, and photoelectric sensor 14 in the photoelectric encoder 2 to convert the position information of the motor shaft into electronic signals. These signals are processed by an analog signal conditioning circuit, captured by a synchronous sampling analog-to-digital converter 16, and converted into digital signals, ultimately fed back to the servo controller 11. This enables precise control of the servo motor 1's position. Furthermore, the analog-to-digital converter 16 can convert analog signals from the position photoelectric encoder 2 into digital signals during servo motor 1 control, allowing the microcontroller or digital controller to process and precisely control the position. This conversion helps achieve higher position accuracy and reduces positional errors. To mitigate errors, in speed control, the analog-to-digital converter 16 can convert the tachogenerator signal into a digital value, enabling the control system to monitor and adjust the motor speed in real time, thereby ensuring stable motor operation and guaranteeing the stability and accuracy of system signal transmission. This reduces faults caused by signal distortion or errors, thus improving system reliability. The turntable antenna 7 is equipped with a servo controller 11 that sends commands to the motor driver 18 via analog or digital signals to drive the turntable antenna 7 motor to rotate. The encoder or rotary transformer 17 built into the turntable antenna 7 detects the antenna azimuth and elevation angles in real time and feeds back the position / speed signals to the servo controller 11, forming a closed-loop adjustment to ensure high-precision target tracking.
