Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation mover speed control, specifically a magnetic levitation mover speed control component. Background Technology

[0002] In fields such as industrial automated transportation and precision equipment drive, the requirements for speed control accuracy, operational stability and equipment integration of moving parts are increasing. Traditional mover drive and speed control devices mostly adopt mechanical contact transmission structures, such as gear transmission and belt transmission. Such structures are prone to transmission gaps due to mechanical wear during long-term operation, resulting in deviation of the mover's running trajectory and large speed fluctuations. This not only reduces control accuracy but also requires frequent maintenance to replace worn parts, increasing equipment operation and maintenance costs and downtime.

[0003] Meanwhile, the drive module and detection module of traditional devices are often set up independently, and the signal transmission between the two is easily affected by external interference. In addition, the overall installation layout of the components is scattered, occupying a large space, which makes it difficult to adapt to the compact industrial equipment installation environment. Furthermore, traditional movers lack effective collision protection design. In the scenario of multi-motor cooperative operation, once an accidental collision occurs, it can easily lead to damage to the movers and load, further affecting the stability and service life of the equipment.

[0004] In addition, the debugging and data interaction methods of traditional devices are relatively simple, relying on dedicated interfaces for program debugging and parameter reading. This is complex and inefficient, and cannot meet the needs of rapid installation and debugging and real-time status monitoring. To address these issues, there is an urgent need for a high-integration, high-precision, stable, and protective actuator speed control component to solve the shortcomings of traditional devices in terms of accuracy, stability, integration, and ease of maintenance. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic levitation mover speed control component.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a magnetic levitation mover speed control component, including a cabinet, a straight section guide rail fixed at the bottom of the cabinet, an arc section guide rail fixed at the arc section of the bottom of the cabinet, multiple mover trolleys movably connected on the straight section guide rail and the arc section guide rail, collision buffer blocks symmetrically fixed on the lower sides of the mover trolleys, multiple coils arranged at the bottom of the interior of the mover trolleys, multiple permanent magnets fixed at the top of the mover trolleys, a driver module arranged inside the side wall of the cabinet, and an encoder module fixed inside the cabinet above the permanent magnets.

[0007] Furthermore, a strip-shaped slot is provided at the bottom of the side wall of the cabinet, and the strip-shaped slot is connected to the moving trolley.

[0008] Furthermore, the driver module includes a driver housing fixed to a rack inside the side wall of the cabinet. A driver base plate is fixed to the front surface of the driver housing. A driver power supply line is fixed to one side above the front surface of the driver base plate. Two motor power supply lines are fixed to the side of the driver base plate near the driver power supply line. A main control board is fixed to the bottom of the front surface of the driver housing. Two USB encoding interfaces are fixed to the front right side of the driver base plate. A communication bus interface is fixed to the other end of the front surface of the driver base plate beyond the USB encoding interfaces.

[0009] Furthermore, the encoder module includes a circuit board fixed inside the strip slot, an encoder interface is fixed on the left side of the front surface of the circuit board, a control board is fixed near the center of the front surface of the circuit board, and multiple Hall sensors are fixed at the bottom of the front surface of the circuit board.

[0010] Furthermore, multiple Hall sensors are located above the permanent magnet, and the spacing between the Hall sensors matches the position of the permanent magnet.

[0011] The beneficial effects of this utility model are:

[0012] Improving speed control accuracy and operational stability: This component forms a closed-loop speed control system through the encoder module and the driver module. The Hall sensor and permanent magnet are precisely matched to detect changes in the position of the moving carriage in real time. After processing by the control board, the speed feedback signal is transmitted to the main control board. The main control board can adjust the coil energizing parameters in real time to effectively avoid speed fluctuations and ensure that the moving carriage runs smoothly along the straight or circular guide rails. This solves the problem of insufficient accuracy caused by wear in traditional mechanical transmission, significantly improving control accuracy. At the same time, the straight and circular guide rails precisely limit the trajectory of the moving carriage, reducing lateral deviation and further ensuring operational stability.

[0013] Improved component integration and space utilization: The cabinet serves as the core installation carrier, integrating the drive module, encoder module, and the moving carriage's running rails. The compact layout of each component and controllable positional accuracy avoid the problems of large space occupation and strong signal interference caused by the dispersed placement of components in traditional devices. In addition, the drive module's internal drive base plate integrates the drive power supply line, motor power supply line, USB encoding interface, and communication bus interface, reducing external wiring, improving the overall integration of components, and making it more suitable for compact industrial installation environments.

[0014] It has reliable collision protection capabilities: The collision buffer blocks on both sides of the underside of the moving trolley are made of elastic material. When multiple moving trolleys operate in coordination or collide with the inner wall of the cabinet, they can absorb the impact force through elastic deformation, avoid damage to the moving trolley, load and internal components, extend the service life of the equipment, reduce the risk of downtime caused by collision, and improve the safety and stability in multi-moving trolley collaborative operation scenarios.

[0015] Simplified debugging process and improved maintenance convenience: The component is equipped with a USB encoding interface and a communication bus interface. The USB encoding interface supports quick connection with external devices, which makes it easy for staff to debug programs, configure parameters and read running data on the main control board. The operation is convenient and efficient. The communication bus interface enables real-time data interaction with external control systems. Staff can remotely monitor the component's operating status, reduce on-site maintenance workload and lower operation and maintenance costs.

[0016] Ensuring long-term operational reliability: The drive housing is made of high-strength insulating material, which can effectively protect the internal components such as the drive base plate and main control board from dust and moisture corrosion, reduce the impact of environmental factors on the components, and the drive base plate also has a heat dissipation function, which can avoid the performance degradation caused by the accumulation of heat in the components, extend the service life of the components, and ensure the long-term stable operation of the components.

[0024] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0025] See Figures 1-6 This is a schematic diagram of the structure of this utility model, a magnetic levitation mover speed control component, including a cabinet 2. The cabinet 2 serves as the core installation and support carrier of the entire component, providing a stable framework for the operation of the mover trolley 1. It is also used to integrate and install key control components such as the driver module 3 and the encoder module 6, ensuring the positional accuracy and collaborative work between the components.

[0026] A linear guide rail 5 is fixed at the bottom of the cabinet 2. The linear guide rail 5 provides a linear running track for the moving trolley 1, limiting its linear motion trajectory, reducing lateral deviation during straight-line travel, and ensuring smooth movement of the moving trolley 1 along a preset linear path. An arc-shaped guide rail 4 is fixed at the arc-shaped section of the bottom of the cabinet 2. The arc-shaped guide rail 4 facilitates a smooth transition of the moving trolley 1 from linear to arc-shaped motion. Its arc-shaped structure matches the arc-shaped section at the bottom of the cabinet 2, providing an arc-shaped motion trajectory for the moving trolley 1, ensuring stability and trajectory accuracy during turning or arc-shaped movement. Multiple moving connections are made on the linear guide rail 5 and the arc-shaped guide rail 4. The moving trolley 1 is the core actuator in the component that realizes the motion function. It is used to carry the load to be transported or driven. It can move in multiple positions by cooperating with the guide rail. At the same time, its internal structure provides installation space for permanent magnet 12 and coil 13. Collision buffer blocks 11 are symmetrically fixed on the lower sides of the moving trolley 1. The collision buffer blocks 11 are made of elastic material. When multiple moving trolleys 1 collide accidentally with each other or with the inner wall of the cabinet 2 and other structures, they can absorb the impact force generated by the collision through their own elastic deformation, so as to avoid damage to the moving trolley 1 and the components on it due to the collision, and at the same time reduce the impact of the collision on the operational stability of the entire component.

[0027] Multiple coils 13 are installed at the bottom of the moving carriage 1. As a key component of magnetic levitation drive, the coils 13 generate a magnetic field when energized. This magnetic field interacts with the magnetic field generated by the permanent magnet 12 to form the power to drive the moving carriage 1 along the guide rail. By changing the magnitude, direction and frequency of the current flowing through the coils 13, the running speed, acceleration and direction of motion of the moving carriage 1 can be adjusted. Multiple permanent magnets 12 are fixed at the top of the moving carriage 1. The permanent magnets 12 can continuously generate a stable magnetic field, which, together with the magnetic field generated by the coils 13 after energization, forms the electromagnetic driving force required for magnetic levitation drive. At the same time, the position distribution of the permanent magnets 12 is adapted to the Hall sensor 63 to provide a magnetic field signal source for the encoder module 6 to detect the position and speed of the moving carriage 1.

[0028] Inside the side wall of cabinet 2, there is a driver module 3. The driver module 3 is the core of the component's power control. It is used to receive control commands from the main control board 35, convert the externally input electrical energy into electrical energy that is compatible with the coil 13, and adjust the energizing parameters of the coil 13 to control the running state of the moving trolley 1. Inside cabinet 2, above the permanent magnet 12, there is an encoder module 6. The encoder module 6 is a position and speed detection component. It detects the changes in the magnetic field of the permanent magnet 12 through the Hall sensor 63, obtains the current position information of the moving trolley 1 in real time, and then converts the position information into an electrical signal and transmits it to the control board 64. After processing, the running speed of the moving trolley 1 is obtained, which provides feedback signals for the driver module 3 to adjust the speed of the moving trolley 1 and realizes closed-loop speed control.

[0029] The bottom of the side wall of the cabinet 2 is provided with a strip-shaped slot. The strip-shaped slot provides space for the connection between the moving trolley 1 and the internal structure of the cabinet 2. At the same time, it facilitates the movement of the moving trolley 1 along the guide rail. Its related components can maintain a stable relative position with the encoder module 6 and other structures in the cabinet 2, ensuring the normal realization of detection and drive functions. The strip-shaped slot is connected to the moving trolley 1.

[0030] The driver module 3 includes a driver housing 31 fixed to the internal rack of the side wall of the cabinet 2. The driver housing 31 is made of a material with certain strength and insulation properties, used to wrap and protect internal components such as the driver base plate 32 and the main control board 35, preventing external dust, moisture and impurities from entering the module and affecting the operation of the components. At the same time, it provides mounting support for the internal components and ensures the stability of the position of each component. The driver base plate 32 is fixed to the front surface of the driver housing 31. The driver base plate 32 is the mounting carrier of the internal components of the driver module 3. It is made of a plate with low conductivity and high structural strength, used to fix the driver power supply line 33, the motor power supply line 34, the USB encoding interface 36 and the communication bus interface 37, etc., and at the same time, it can also play a certain role in heat dissipation. To prevent heat buildup during component operation, a driver power supply line 33 is fixed to one side of the front surface of the driver base plate 32. The driver power supply line 33 connects the external power source to the driver module 3, transmitting external power to the driver module to provide the necessary power for the various components on the driver base plate 32 and the main control board 35, ensuring the normal operation of the driver module 3. Two motor power supply lines 34 are fixed to the side of the driver base plate 32 near the driver power supply line 33. The motor power supply lines 34 serve as the power transmission channel between the driver module 3 and the coil 13, accurately transmitting the processed power from the driver module 3 to the coil 13 of the moving trolley 1, providing the current required for driving the coil 13. Their dual-line design can correspond to different coils. The drive unit can achieve bidirectional current transmission to meet the needs of different motion states of the moving trolley 1. A main control board 35 is fixed at the bottom of the front surface of the drive unit housing 31. The main control board 35 is the control core of the drive unit module 3, integrating a microprocessor, memory, and various control circuits. It receives speed and position feedback signals transmitted by the encoder module 6, generates control commands for the coil 13 based on a preset control program, and then transmits the commands to the drive circuit inside the drive unit to achieve precise control of the moving trolley 1's running state. Simultaneously, it can interact with an external control system via the communication bus interface 37, receiving external control commands and providing feedback on component operating status. Two USB encoding interfaces 36 are fixed on the front right side of the drive unit base plate 32. The encoding interface 36 is mainly used for temporary data interaction between the driver module 3 and external devices. It can realize the debugging of the internal program of the main control board 35, parameter configuration and reading of running data, which facilitates the installation, debugging and subsequent maintenance of the component by the staff. Its dual interface design can connect different devices at the same time, improving the efficiency of debugging and maintenance. The other end of the front surface of the driver base plate 32 away from the USB encoding interface 36 is fixed with a communication bus interface 37. The communication bus interface 37 serves as a long-term stable communication channel between the component and the external control system. It adopts the bus communication protocol to realize high-speed and reliable data transmission. It can receive control commands from the external control system in real time and feed back the component's operating status data to the external system, realizing the collaborative work of the entire component and the external control system.

[0031] The encoder module 6 includes a circuit board 62 fixed inside a strip-shaped slot. The circuit board 62 serves as the mounting and circuit connection carrier for the internal components of the encoder module 6, integrating various conductive lines to realize the circuit connection between the encoder interface 61, the control board 64, and the Hall sensor 63, ensuring stable signal transmission between components and providing mounting support for each component to ensure accurate component positioning. The encoder interface 61 is fixed on the left side of the front surface of the circuit board 62. The encoder interface 61 serves as the signal transmission interface between the encoder module 6 and external devices, transmitting the speed and position signals of the moving trolley 1 processed by the control board 64 to the main control board 35 to provide feedback for the control of the driver module 3. It can also receive control signals from external devices to adjust the detection parameters of the encoder module 6. The control board 64 is fixed near the center of the front surface of the circuit board 62. The control board 64 is responsible for signal processing of the encoder module 6. The core component integrates a signal amplification circuit, a filtering circuit, and a data processing chip. It receives the raw magnetic field signal transmitted by the Hall sensor 63, amplifies, filters, and digitizes the signal, converting it into a digital signal that reflects the position of the moving trolley 1. Then, it calculates the running speed of the moving trolley 1 and finally transmits the position and speed signals to the main control board 35. Multiple Hall sensors 63 are fixed at the bottom of the front surface of the circuit board 62. The Hall sensor 63 is the signal detection element of the encoder module 6. Utilizing the Hall effect principle, when the moving trolley 1 moves, the permanent magnet 12 moves with it. The Hall sensor 63 detects the change in the magnetic field of the permanent magnet 12 and outputs a corresponding electrical signal. This signal can reflect the current position of the permanent magnet 12 in real time. The distribution design of multiple sensors can improve the accuracy and resolution of position detection, ensuring the accuracy of position and speed detection of the moving trolley 1. Multiple Hall sensors 63 are located above the permanent magnet 12, and the spacing between the Hall sensors 63 matches the position of the permanent magnet 12. This position matching design ensures that each Hall sensor 63 can accurately detect the magnetic field change of the corresponding permanent magnet 12, avoiding the loss or error of detection signal due to mismatch in spacing, ensuring the continuity and accuracy of the output signal of the Hall sensor 63, and thus providing a reliable guarantee for the detection of the speed and position of the moving trolley 1.

[0032] When using this utility model:

[0033] First, the rack 2 provides the overall installation support frame, and the driver module 3 integrated inside it starts working as the core control unit. The external power supply inputs electrical energy through the driver power supply line 33 of the driver module 3, and distributes it to the main control board 35 through the driver base plate 32. The main control board 35 combines the preset program or the external control command received through the communication bus interface 37 to generate control signals for the movement of the mover, and transmits the signals to the drive circuit.

[0034] After the drive circuit processes the current, the appropriate current is precisely delivered to the coil 13 at the bottom of the moving carriage 1 through the motor power supply line 34. After the coil 13 is energized, it generates a magnetic field, which interacts with the stable magnetic field generated by the permanent magnet 12 fixed at the top of the moving carriage 1 to form an electromagnetic driving force, which pushes the moving carriage 1 to move along the straight section guide rail 5 or the arc section guide rail 4 at the bottom of the cabinet 2 to achieve linear or arc-shaped trajectory movement.

[0035] During the movement of the moving trolley 1, the encoder module 6 located above the permanent magnet 12 inside the cabinet 2 synchronously starts the detection function. Multiple Hall sensors 63 fixed on the circuit board 62 of the encoder module 6, because they are matched with the position of the permanent magnet 12, can detect the change of magnetic field of the permanent magnet 12 as it moves with the moving trolley 1 in real time, convert the change of magnetic field into an electrical signal and transmit it to the control board 64.

[0036] The control board 64 amplifies, filters, and digitizes the electrical signal to calculate the current position and running speed of the moving trolley 1. Then, it transmits the processed speed and position feedback signals to the main control board 35 through the encoder interface 61. The main control board 35 compares the feedback signal with the preset target speed and adjusts the current parameters output to the coil 13 in real time, thereby fine-tuning the running speed of the moving trolley 1 to form a speed closed-loop control and ensure the stable operation of the moving trolley 1.

[0037] In addition, the collision buffer blocks 11 on both sides of the lower part of the moving carriage 1 can absorb the impact force through elastic deformation in the event of an accidental collision, protecting the moving carriage 1 and other components of the assembly. If it is necessary to debug the assembly or read data, the staff can connect to external devices through the USB encoding interface 36 to debug the program of the main control board 35 or obtain the running data. The strip slot at the bottom of the side wall of the cabinet 2 provides the necessary space for the movement of the moving carriage 1 and its cooperation with the encoder module 6, ensuring the continuity and stability of the overall assembly operation.
