Description

Technical Field

[0001] The utility model belongs to the technical field of industrial automation test and measurement, and particularly relates to a rapid debugging device for an inductive encoder. Background Art

[0002] An encoder is a sensor used to detect linear displacement, angular displacement, linear velocity, and angular velocity, and convert the detected signals into digital signals. Traditional optoelectronic encoders have problems such as high cost and low environmental adaptability. Resolvers have disadvantages such as low resolution and complex structures. Inductive encoders based on electromagnetic induction technology have received attention due to their advantages such as high resolution, compact structure, and high environmental adaptability.

[0003] During the debugging and installation process of existing inductive encoders, it is necessary to manually connect an oscilloscope and observe the waveform to adjust the installation position of the inductive encoder to be installed. The method of manually observing the oscilloscope waveform not only has low production efficiency but also large errors. Therefore, a device for rapid debugging of inductive encoders needs to be designed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rapid debugging device for an inductive encoder, which can rapidly debug the inductive encoder to solve the problems of high manual dependence and low production efficiency in the production process of inductive encoders in the prior art.

[0005] The solution to achieve the purpose of the utility model is as follows:

[0006] A rapid debugging device for an inductive encoder includes a bench, on which a motor rotor, a motor stator, and a motor housing are installed, and a controller. It is characterized in that a junction box is installed on the bench, and the junction box is provided with a power input terminal, an inductive encoder power connection terminal, an inductive encoder signal input terminal, and a display screen. The power input terminal is connected to the inductive encoder power connection terminal through a wire; the controller is installed in the junction box, and there is a signal transmission between the inductive encoder signal input terminal and the controller, and a signal transmission between the display screen and the controller.

[0007] The display screen is connected to the controller through pin headers. The controller is installed below the digital display screen for reading the inductive encoder signal, resolving it into a digital quantity, and controlling the display information of the display screen.

[0008] Both the inductive encoder power connection terminal and the inductive encoder signal input terminal adopt a terminal block structure.

[0009] The power input terminal, the inductive encoder power connection terminal, the inductive encoder signal input terminal, and the display screen are all embedded in the junction box. A row can be embedded on the surface of the junction box.

[0010] When debugging the inductive encoder, the stator and rotor of the inductive encoder are respectively fixedly installed on the motor stator and the motor rotor. The signal output line of the inductive encoder is connected to the signal input terminal of the inductive encoder, and the power supply line of the inductive encoder is connected to the power supply connection terminal of the inductive encoder.

[0011] The inductive encoder described is a non-contact high-precision absolute encoder, with a stator and a rotor provided.

[0012] For the convenience of installing the motor housing, preferably, there is an opening on the bench, and a coupling is embedded in the opening. The motor shaft is fixedly connected to the coupling, and the motor housing is installed above the coupling.

[0013] Preferably, the display screen adopts a digital display screen.

[0014] The digital display screen is used to display the calculated angle value; the controller is used to process the read analog signal and convert it into a digital quantity; the power input terminal is embedded in the top of the junction box housing and is used to supply power to the controller and the inductive encoder.

[0015] When the number of pole pairs of the inductive encoder to be installed changes, the digital display screen can still correctly display the angle information, that is, the digital display screen displays the electrical angle of the inductive encoder to be installed.

[0016] When the distance between the stator and the rotor of the inductive encoder to be installed changes, the controller can still correctly calculate the angle information and display it through the digital display screen.

[0017] Advantages of the present utility model:

[0018] Convenient operation: Through interfaces such as the power input terminal, the power supply connection terminal of the inductive encoder, the signal input terminal of the inductive encoder, and the display screen on the junction box, users can easily complete operations such as power connection, signal transmission, and data display. This design greatly simplifies the debugging process and reduces the operation difficulty.

[0019] Efficient debugging: The controller is installed in the junction box and realizes signal transmission connection with the signal input terminal of the inductive encoder and the display screen. This means that during the debugging process, the controller can receive the signals of the inductive encoder in real time and quickly process these data, thereby realizing precise control of the motor performance. This efficient data processing ability helps to shorten the debugging time and improve the debugging efficiency.

[0020] Real-time feedback: The introduction of the display screen enables key parameters and status information during the debugging process to be displayed to the user in real time. Users can adjust the debugging parameters in a timely manner according to the information on the display screen to ensure that the motor performance reaches the best state. This real-time feedback mechanism helps to improve the accuracy and reliability of debugging. Description of the Drawings

[0035] The power adapter 6 of the controller is connected to the AC220V power supply interface to supply power to the controller and the inductive encoder.

[0036] The following details a usage process of an embodiment of the present utility model:

[0037] First, place the stator 10 of the inductive encoder at the motor stator positioning position on the motor end face, and connect the power adapter 6 of the controller to the AC220V power supply interface; then, set the switching power supply and turn on the switching power supply; again, while manually rotating the stator 10 of the inductive encoder, observe the display value on the digital display screen 3 until the display value on the digital display screen 3 is near 0 and then stop rotating; finally, tighten the screws at the screw holes of the stator 10 of the inductive encoder, fix it on the motor housing 9, and turn off the switching power supply 12.

[0038] The embodiment of the present utility model collects the electrical signals output by the inductive encoder, then performs angle calculation, and displays it on the digital display screen; not only replaces the process of workers observing the electrical signals output by the encoder by operating an oscilloscope, but also the display is more intuitive, simplifies the installation process of the inductive encoder, and improves the installation efficiency of the inductive encoder.
