Description

Technical Field

[0001] The present invention relates to the field of stepper motors, and in particular to a stepper motor control method and device. Background Art

[0002] A stepper motor is an electric motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates an angle or moves forward one step. The output angular displacement or linear displacement is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. Therefore, a stepper motor is also called a pulse motor. A stepper motor control device is a device used to control the movement of a stepper motor. It is usually composed of a controller, a driver, a stepper motor and other components.

[0003] At present, when stepper motor control devices are implemented, the control devices are generally assembled and installed inside a small control housing. The control device will generate heat during operation, and the heat generation will reduce the service life of the device. Traditional heat dissipation holes not only have slow heat dissipation effect and no adjustment function, but are also easily blocked by flowing dust, which further reduces the service life of the device and reduces the control efficiency of the stepper motor. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a stepper motor control device, which overcomes the deficiencies of the prior art and solves the problem that, when the current stepper motor control device is implemented, the control device is generally assembled and installed inside a narrow control housing, and the control device will generate heat during operation, and the heat generation will reduce the service life of the device, while the traditional heat dissipation holes not only have slow heat dissipation effect and lack adjustment function, but are also easily blocked by flowing dust, thereby further reducing the service life of the device and reducing the control efficiency of the stepper motor.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a stepper motor control device, comprising a controller housing and a stepper motor body arranged on one side of the controller housing, movable grooves are respectively opened on both side surfaces of the controller housing, and five groups of rotating plates are rotatably installed inside the controller housing located inside the two movable grooves, connecting plates are respectively fixedly installed on both sides of each group of rotating plates, brushes are respectively fixedly installed on one side of the two connecting plates away from the corresponding rotating plates, protective housings are respectively fixedly installed on both sides of the controller housing, filter plates are fixedly installed on one side of the protective housing away from the controller housing, the brushes are in contact with the filter plates, and a linkage driving mechanism is provided on one side of multiple groups of rotating plates.

[0006] By adopting the above technical scheme, when in use, the two groups of rotating plates are driven to rotate through the linkage mechanism, and then the two groups of rotating plates can play a role in heat dissipation inside the controller shell when rotating, and the rotating plate opening can be adjusted to facilitate heat dissipation, and the protective shell can protect the rotating plate and the connecting plate to prevent the rotating plate from causing harm to the staff when rotating. The filter plate will stick to dust during the heat dissipation process, and then the rotating plate can drive the connecting plate and the brush to rotate. Every time the brush rotates, the bristles will contact the filter plate, and the bristles will penetrate the holes of the filter plate, thereby cleaning the filter plate, enhancing the heat dissipation effect inside the controller shell, preventing damage to internal equipment, and enhancing the control effect of the stepper motor.

[0007] As a preferred technical solution of the present invention, a rear cover is fixedly mounted on the outer wall of one side of the controller housing, a driver is mounted on the inner wall of the rear cover, and the driver is electrically connected to the stepper motor.

[0008] By adopting the above technical solution, the controller housing can be fixed by the back cover, and the arrangement of the back cover can facilitate the maintenance of the equipment inside the controller housing by the staff.

[0009] As a preferred technical solution of the present invention, a PLC and a power supply are fixedly installed on the inner wall of the rear cover below the driver, and the power supply, PLC, driver and stepper motor are electrically connected.

[0010] By adopting the above technical solution, the PLC and the power supply can be fixed through the back cover.

[0011] As a preferred technical solution of the present invention, the linkage drive mechanism includes multiple groups of pulleys, the multiple groups of pulleys are fixedly connected to the rotating shafts of the corresponding rotating plates, and the outer walls of the multiple groups of pulleys are respectively equipped with belts for transmission.

[0012] By adopting the above technical solution, the rotating plate can fix multiple groups of pulleys, and the cooperation between the pulleys and the belts can facilitate the linkage rotation of multiple groups of rotating plates.

[0013] As a preferred technical solution of the present invention, two driving motors are installed on the side of the controller housing away from the pulley, and the output shafts of the two driving motors are respectively fixedly connected to the rotating shafts of the corresponding rotating plates.

[0014] By adopting the above technical solution, the controller housing can fix the drive motor, and the drive motor can drive the rotating plate to rotate.

[0015] As a preferred technical solution of the present invention, a storage shell is installed on the outer wall of the controller shell located outside the multiple groups of pulleys, and a cover plate is fixedly installed on the outer wall of the storage shell.

[0016] By adopting the above technical solution, the controller shell can fix the storage shell, and the cover plate can close the storage shell, which makes it convenient for staff to repair the pulley and belt.

[0017] As a preferred technical solution of the present invention, a display, a control panel and a switch are installed on the outer wall of the controller housing, and the display, the control panel, the PLC and the power supply, the power supply, the PLC, the driver, the drive motor and the stepper motor are electrically connected.

[0018] By adopting the above technical solution, the display, control panel and switch can be fixed by the controller housing.

[0019] A stepper motor control method comprises the following steps: Step 1: The user first starts the stepper motor main control device through the control panel. The power supply supplies power to the entire system, and the PLC (Programmable Logic Controller) starts initialization and checks the connection status of each component, including the driver, stepper motor body, display, control panel and switch.

[0020] Step 2: Set parameters. The user enters the required stepper motor body motion parameters on the control panel, such as step size, speed, rotation direction, etc. The PLC receives these parameters and stores them in the internal memory, ready for execution.

[0021] Step 3: The drive motor starts. The PLC sends a start signal to the drive motor according to the set parameters. The drive motor starts working. Its output shaft is connected to multiple sets of rotating plates through a belt and pulley transmission mechanism, driving the rotating plates to rotate. The brushes that clean the filter plates start to contact and move with the rotation of the rotating plates. The brushes connected to both sides of the rotating plates start to contact and move with the filter plates. The brushes slide on the surface of the filter plates, effectively removing dust, impurities, etc. on the filter plates and keeping the filter plates clean.

[0022] Step 4: The stepper motor body moves. At the same time, the driver receives the instructions from the PLC and controls the movement of the stepper motor body according to the set parameters. Under the precise control of the control device, the stepper motor body rotates according to the set step size and speed to achieve the required motion trajectory.

[0023] Step 5: Status monitoring and feedback. PLC monitors the operating status of the stepper motor in real time, including position, speed, etc. If the stepper motor has an abnormal situation (such as overload, loss of step, etc.), PLC will immediately send out an alarm signal and display the error information through the display. Users can understand the operating status of the stepper motor through the information on the display and take corresponding measures.

[0024] Step 6: Stop and reset. When the stepper motor body completes the set motion trajectory, the PLC sends a stop signal to the drive motor and the driver. The drive motor and the stepper motor body stop working, and the system enters the standby state. Through the above work flow, the control device can accurately control the movement of the stepper motor body and realize the cleaning function of the filter plate to ensure the stability and reliability of the system.

[0025] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention drives two sets of rotating plates to rotate through a linkage mechanism, and then the two sets of rotating plates can dissipate heat inside the controller housing when they rotate. The rotating plates can be adjusted to facilitate heat dissipation, and the protective housing can protect the rotating plates and the connecting plates to prevent the rotating plates from causing harm to the staff when they rotate. The filter plate will stick to dust during the heat dissipation process, and then the rotating plate can drive the connecting plate and the brush to rotate. Each time the brush rotates, the bristles will contact the filter plate, and the bristles will penetrate the holes of the filter plate, thereby cleaning the filter plate, thereby enhancing the heat dissipation effect inside the controller housing, preventing damage to internal equipment, and enhancing the control effect of the stepper motor.

[0026] (2) The present invention can drive a group of rotating plates to rotate through a driving motor, and then with the cooperation of a pulley group and a belt, multiple rotating plates can be driven to rotate in a linked manner, so as to facilitate the synchronous adjustment of opening heat dissipation for different rotating plates.

[0027] (3) The present invention realizes the movement of the stepper motor body through the movement of the stepper motor body. At the same time, the driver receives the instruction of the PLC and controls the movement of the stepper motor body according to the set parameters. Under the precise control of the control device, the stepper motor body rotates according to the set step length and speed to achieve the required motion trajectory, state monitoring and feedback. The PLC monitors the operating state of the stepper motor body in real time, including position, speed, etc. If the stepper motor body has an abnormal situation (such as overload, loss of step, etc.), the PLC will immediately send an alarm signal and display an error message on the display. The user can understand the operating state of the stepper motor body through the information on the display and perform corresponding processing. Through the above work flow, the control device can accurately control the movement of the stepper motor body. BRIEF DESCRIPTION OF THE DRAWINGS
