Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more specifically to a magnetic levitation flexible conveying system. Background Technology

[0002] With the trend of intelligent and precise development in modern industrial production, magnetic levitation flexible conveying systems are widely used in fields such as electronic manufacturing and precision instrument assembly due to their non-contact conveying characteristics.

[0003] However, existing magnetic levitation flexible conveyor systems rely on single magnetic force control. Under high-speed operation or load changes, it is difficult to precisely control the position and trajectory of the levitation body, leading to material conveying deviations and insufficient conveying accuracy, failing to meet the demands of high-precision production. Furthermore, while magnetic levitation systems achieve non-contact actuation, the auxiliary guiding and supporting structures still have mechanical contact, leading to severe wear after long-term operation. This not only shortens equipment lifespan but also increases maintenance costs and downtime. Moreover, wear on the auxiliary guiding and supporting structures makes the magnetic levitation flexible conveyor system prone to fluctuations in levitation height and trajectory deviations, especially during long-term continuous operation, where stability issues become more pronounced, severely impacting the reliability of material conveying and hindering the effective guarantee of system stability and conveying efficiency.

[0004] Therefore, how to develop a magnetic levitation flexible conveying system that combines high-precision control, low wear, and high stability to achieve precise positioning and trajectory control of the suspended body under complex working conditions, while optimizing the auxiliary guidance and support structure to eliminate mechanical contact loss and improve the reliability and conveying efficiency of the system during long-term continuous operation, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

A first magnetic body is fixedly installed inside the installation groove. A cover plate is detachably connected to the slider, and a connecting seat is installed on the cover plate. The magnetic drive module and the detection module are respectively installed on the two sides of the connecting seat.

[0009] Furthermore, the suspended gas module includes an air pump, the output end of which is fixedly and sealed to an output pipe, the end of which, away from the air pump, is fixedly and sealed to a pressure stabilizing tank, an electrically controlled valve is fixedly and sealed to the pressure stabilizing tank, a positive pressure pipe is sealed to the electrically controlled valve, and the positive pressure pipe is sealed to the gas guide channel.

[0010] Furthermore, the magnetic drive module includes a second magnetic body, and a first mounting plate is fixedly installed on one side of the connecting seat, with the second magnetic body fixed on the first mounting plate; a plurality of equidistantly distributed electromagnetic components are fixedly installed on one side of the mounting bracket, the electromagnetic components being arranged along the length direction of the guide rail, and the electromagnetic components being arranged corresponding to the second magnetic body.

[0011] Furthermore, the control module includes a controller, which is electrically connected to the suspended gas module, the magnetic drive module, and the detection module. The controller is also electrically connected to a control panel and a display.

[0012] Furthermore, the detection module includes a grating ruler, and a second mounting plate is fixedly installed on one side of the connecting seat, and the grating ruler is fixedly installed on the second mounting plate; a plurality of equidistantly distributed grating detectors are fixedly installed on one side of the mounting bracket, the grating detectors are electrically connected to the control module, the grating detectors are arranged along the length direction of the guide rail, and the grating detectors are correspondingly arranged with the grating ruler.

[0013] Furthermore, the magnetic valve assembly includes a valve stem, and each of the air guide holes has an installation cavity communicating with the air guide channel. A valve plate is fixedly and sealed inside the installation cavity, and a valve hole is opened on the valve plate. The valve stem is sealed and slidably connected inside the valve hole. An air guide groove is opened on the outer side of the valve stem near the air guide channel. A sealing disc is fixedly and sealed to the end of the valve stem away from the air guide channel. A magnetic ball is fixedly installed on the end of the valve stem near the air guide channel. The magnetic ball is magnetically attracted to the moving part suspension module.

[0014] Furthermore, a limiting ring is fixedly installed at one end of the valve stem near the magnetic ball, and a spring is fitted on the valve stem, with the spring abutting and connecting between the limiting ring and the valve plate.

[0017] Beneficial effects achieved:

[0018] This application adopts a combination of gas suspension and magnetic drive, which reduces the error caused by mechanical contact. With the real-time monitoring of the detection module and the precise control of the control module, it can achieve precise control of the position and motion trajectory of the moving part suspension module, meet the needs of high-precision material conveying, and is suitable for industries such as electronics and precision instruments that have extremely high requirements for conveying accuracy.

[0019] This application utilizes the gas film formed by the suspended gas module to prevent direct contact between the mover suspension module and the guide rail, significantly reducing frictional losses. The magnetic drive module employs a non-contact drive, avoiding wear on mechanical transmission components. This results in low operating resistance and low energy consumption for the entire conveying system, while extending the equipment's service life and reducing maintenance costs and frequency.

[0020] This application utilizes a detection module to monitor the system's operating status in real time, and a control module to provide timely feedback and adjustments, ensuring that the moving part suspension module maintains a stable suspension and motion state during the conveying process. Even when faced with external interference or load changes, the system can quickly adjust, ensuring the reliability of the conveying process and reducing the risk of failure during production.

[0028] The following is in conjunction with the appendix Figure 1-6This application will be described in further detail.

[0029] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] This application discloses a magnetic levitation flexible transport system.

[0032] Please refer to the above as well. Figures 1 to 6 In one embodiment of this application, a magnetic levitation flexible conveying system includes a stator guide rail module 100, a mover levitation module 200 slidably connected to the stator guide rail module 100, a levitation gas module 300 connected to the stator guide rail module 100 corresponding to the mover levitation module 200, a magnetic drive module 400 disposed between the stator guide rail module 100 and the mover levitation module 200, a control module 500 electrically connected to the levitation gas module 300 and the magnetic drive module 400, and a detection module 600 electrically connected to the control module 500; the stator guide rail module 100 includes a mounting base 1. 01. A mounting bracket 102 is fixedly mounted on the mounting base 101. A guide rail 103 is fixedly mounted on the mounting bracket 102. The moving part suspension module 200 is mounted on the guide rail 103. The guide rail 103 has evenly distributed air guide holes 104 along its length toward the moving part suspension module 200. A magnetic suction valve assembly 700 is sealed inside each air guide hole 104. The moving part suspension module 200 is magnetically connected to the magnetic suction valve assembly 700. An air guide channel 105 is opened inside the guide rail 103, which connects all the air guide holes 104. The air guide channel 105 is connected to the suspension gas module 300.

[0033] During operation, the suspending gas module 300 generates high-pressure gas, which enters the various air guide holes 104 on the guide rail 103 through the air guide channel 105. The moving part suspending module 200 is magnetically connected to the magnetic suction valve assembly 700. When the moving part suspending module 200 approaches the corresponding magnetic suction valve assembly 700, the magnetic suction principle controls the magnetic suction valve assembly 700 to open, thereby causing the high-pressure gas to be discharged from the air guide holes 104. A uniform gas film is formed between the guide rail 103 and the moving part suspending module 200, so that the moving part suspending module 200 is suspended above the guide rail 103, effectively reducing the frictional resistance between the two.

[0034] Under the control of the control module 500, the magnetic drive module 400 generates a magnetic field with a specific direction and intensity. The magnetic force generated by the magnetic drive module 400 acts on the levitation module 200, driving it to move along the length of the guide rail 103. The control module 500 precisely controls the changes in the magnetic field of the magnetic drive module 400 according to the preset conveying path and speed requirements, realizing the flexible movement of the levitation module 200.

[0035] The detection module 600 monitors the position of the moving part suspension module 200 in real time and feeds back the position status to the control module 500 in the form of an electrical signal. Based on the feedback signal, the control module 500 adjusts the gas pressure of the suspension gas module 300 and the magnetic field strength and direction of the magnetic drive module 400 in real time to ensure that the moving part suspension module 200 can operate stably along a predetermined path and speed, while ensuring the reliability of the suspension effect.

[0036] Please refer to the above as well. Figures 1 to 6 In one embodiment of this application, the guide rail 103 is provided with a first connection hole 106 communicating with the gas guide channel 105, the mounting bracket 102 is provided with a second connection hole 107 communicating with the first connection hole 106, and a connecting pipe 108 communicating with the second connection hole 107 is fixedly and sealed on the mounting bracket 102. The end of the connecting pipe 108 away from the mounting bracket 102 is connected to the suspended gas module 300.

[0037] During operation, the gas generated by the levitation gas module 300 is transmitted through the connecting pipe 108. The connecting pipe 108 is sealed to the second connecting hole 107 on the mounting bracket 102, and the gas enters the mounting bracket 102 through the second connecting hole 107. Subsequently, the gas enters the air guiding channel 105 inside the guide rail 103 through the first connecting hole 106, which is sealed to the second connecting hole 107. Finally, the gas exits from the air guiding channel 105 through the evenly distributed air guiding holes 104, forming an air film between the guide rail 103 and the moving part levitation module 200, thus achieving the levitation of the moving part levitation module 200. The connections between the first connecting hole 106 and the second connecting hole 107, and between the second connecting hole 107 and the connecting pipe 108, are all sealed. This sealing design ensures that the gas does not leak during transmission and guarantees that all the gas can enter the air guiding channel 105. A stable gas supply is key to forming a stable air film, and the sealed connection effectively ensures the stability of the levitation effect of the moving part levitation module 200.

[0038] Please refer to the above as well. Figures 1 to 6 In one embodiment of this application, the levitation module 200 includes a slider 201, which is slidably connected to the guide rail 103. A groove 202 is formed on the side of the slider 201 close to the guide rail 103 corresponding to the cross-sectional shape of the guide rail 103. A gap for forming an air film is provided between the inner surface of the groove 202 and the outer surface of the guide rail 103. An installation groove 203 is formed on the side of the slider 201 away from the guide rail 103 corresponding to the magnetic valve assembly 700. A first magnetic body 204 is fixedly installed inside the installation groove 203. A cover plate 205 is detachably connected to the slider 201. A connecting seat 206 is installed on the cover plate 205. The magnetic drive module 400 and the detection module 600 are respectively installed on the two sides of the connecting seat 206.

[0039] During operation, the groove 202 on the slider 201 matches the cross-sectional shape of the guide rail 103, achieving a sliding connection. When the suspending gas module 300 is working, gas is discharged through the air guide channel 105 and the air guide hole 104, forming an air film between the guide rail 103 and the slider 201. Due to the fitted design of the groove 202 and the guide rail 103, the air film is better constrained, allowing the slider 201 to be stably suspended on the guide rail 103. At the same time, the first magnetic body 204 in the mounting groove 203 on the slider 201 is magnetically connected to the magnetic suction valve assembly 700 in the air guide hole 104. When the moving part suspending module 200 approaches the corresponding magnetic suction valve assembly 700, the magnetic suction valve assembly 700 will open under the magnetic force of the first magnetic body 204. This avoids air leakage caused by the opening of the magnetic suction valve assemblies 700 in other air guide holes 104 on the guide rail 103, ensuring the suspending effect of the suspending gas module 300 on the moving part suspending module 200.

[0040] Please refer to the above as well. Figures 1 to 6In one embodiment of this application, the suspended gas module 300 includes an air pump 301. The output end of the air pump 301 is fixedly and sealed to an output pipe 302. The end of the output pipe 302 away from the air pump 301 is fixedly and sealed to a pressure stabilizing tank 303. An electric control valve 304 is fixedly and sealed to the pressure stabilizing tank 303. A positive pressure pipe 305 is sealed to the electric control valve 304. The positive pressure pipe 305 is sealed to the gas guide channel 105.

[0041] During operation, the air pump 301 starts and draws in air. This gas is output through the output pipe 302, which is fixedly and sealed to the output end of the air pump 301. The output pipe 302 delivers the gas to the pressure stabilizing tank 303, which buffers and stabilizes the gas pressure. The electrically controlled valve 304 connected to the pressure stabilizing tank 303 can adjust its opening to control the gas output. Under the control of the control module 500, the electrically controlled valve 304 precisely regulates the gas flow and pressure. According to the actual operating requirements of the moving element suspension module 200, the regulated gas enters the air guide channel 105 of the guide rail 103 through the positive pressure pipe 305, and finally exits from the air guide hole 104, forming a stable gas film between the guide rail 103 and the moving element suspension module 200, thus achieving the suspension and stable operation of the moving element suspension module 200.

[0042] Please refer to the above as well. Figures 1 to 6 In one embodiment of this application, the magnetic drive module 400 includes a second magnetic body 401. A first mounting plate 402 is fixedly installed on one side of the connecting seat 206, and the second magnetic body 401 is fixed on the first mounting plate 402. A plurality of equidistantly distributed electromagnetic components 403 are fixedly installed on one side of the mounting bracket 102. The electromagnetic components 403 are arranged along the length direction of the guide rail 103, and the electromagnetic components 403 are correspondingly arranged with the second magnetic body 401.

[0043] During operation, the control module 500 supplies power to the electromagnetic components 403 equidistantly distributed on the side of the mounting bracket 102, which generate a magnetic field. A magnetic circuit is formed between the electromagnetic components 403 and the second magnetic body 401. By controlling the magnitude and direction of the current in the electromagnetic components 403, the strength and direction of the generated magnetic field can be adjusted. When the magnetic field generated by the electromagnetic components 403 interacts with the second magnetic body 401, a magnetic force is generated according to the principle of like poles repelling and unlike poles attracting. Under the action of the magnetic force, the second magnetic body 401 drives the connecting seat 206 and the entire moving levitation module 200 to move along the length of the guide rail 103. The control module 500 continuously monitors the position, speed, and other information of the moving levitation module 200 fed back by the detection module 600, and adjusts the current parameters of the electromagnetic components 403 in real time, thereby changing the magnetic field characteristics and achieving precise control over the direction, speed, and position of the moving levitation module 200.

[0044] Please refer to the above as well. Figures 1 to 6In one specific embodiment of this application, both the first magnetic body 204 and the second magnetic body 401 are made of permanent magnet materials, such as neodymium iron boron (NdFeB) permanent magnets. NdFeB is currently the strongest magnetic material among commercially available permanent magnet materials, providing a powerful magnetic field force, suitable for scenarios where the drive module requires high thrust. It also has a smaller volume for the same magnetic force, contributing to the miniaturization and weight reduction of the mover levitation module. In the magnetic drive module 400, the NdFeB permanent magnet enables the electromagnetic component 403 to generate sufficient driving force with a smaller current, reducing energy consumption.

[0045] It is understood that in other embodiments of this application, the first magnetic body 204 and the second magnetic body 401 may also be samarium cobalt permanent magnets. Samarium cobalt permanent magnets not only have excellent high-temperature stability, but also good chemical stability, corrosion resistance, and are not easily oxidized, which helps to extend their service life.

[0046] Please refer to the above as well. Figures 1 to 6 In one embodiment of this application, the control module 500 includes a controller 501, which is electrically connected to the suspended gas module 300, the magnetic drive module 400, and the detection module 600. The controller 501 is electrically connected to a control panel 502 and a display 503.

[0047] The detection module 600 monitors the position of the moving part suspension module 200 in real time and feeds back the position status to the control module 500 in the form of an electrical signal. Based on the feedback signal, the control module 500 adjusts the gas pressure of the suspension gas module 300 and the magnetic field strength and direction of the magnetic drive module 400 in real time to ensure that the moving part suspension module 200 can operate stably along a predetermined path and speed, while ensuring the reliability of the suspension effect.

[0048] During operation, the detection module 600 monitors the position and velocity signals of the levitation module 200 in real time and feeds them back to the controller 501. The controller 501, as the core of the control module 500, analyzes and processes the received data to determine whether the current state of the system meets the preset parameter requirements.

[0049] Operators can input various operating commands into controller 501 via control panel 502, such as adjusting operating speed, starting or stopping the system. After receiving the commands, controller 501 makes corresponding adjustments to the system. Simultaneously, display 503 shows the system's operating parameters, working status, and fault information in real time, allowing operators to intuitively understand the system's operation and promptly identify and address problems.

[0050] Based on the data analysis results, the controller 501, in conjunction with the preset control program and the instructions input by the operator through the control panel 502, sends control signals to the suspended gas module 300 and the magnetic drive module 400.

[0051] For example, when the speed of the levitation module 200 is detected to be lower than the set value, the controller 501 will send a command to the magnetic drive module 400 to increase the current of the electromagnetic component 403 and enhance the magnetic field force, thereby increasing the operating speed of the levitation module 200 to maintain a stable working state.

[0052] Please refer to the above as well. Figures 1 to 6 In one embodiment of this application, the detection module 600 includes a grating ruler 601. A second mounting plate 602 is fixedly installed on one side of the connecting seat 206, and the grating ruler 601 is fixedly installed on the second mounting plate 602. A plurality of equidistantly distributed grating detectors 603 are fixedly installed on one side of the mounting bracket 102. The grating detectors 603 are electrically connected to the control module 500. The grating detectors 603 are arranged along the length direction of the guide rail 103, and the grating detectors 603 are correspondingly arranged with the grating ruler 601.

[0053] During operation, the grating ruler 601 is fixedly mounted on the second mounting plate 602 of the connecting seat 206 and moves together with the moving part suspension module 200. Grating detectors 603, evenly distributed on the side of the mounting bracket 102, are arranged along the length of the guide rail 103 and correspond to the grating ruler 601. When the moving part suspension module 200 moves on the guide rail 103, the grating ruler 601 moves accordingly, passing each grating detector 603. The grating ruler 601 has fine graduations, and the grating detectors 603 convert physical displacement into electrical signals by detecting changes in the graduations. Each time a specific graduation is passed, the grating detector 603 generates a pulse signal. By counting and processing these pulse signals, the position and displacement of the moving part suspension module 200 can be accurately calculated.

[0054] The control module 500 calculates the operating speed of the mover levitation module 200 based on the number of pulses generated by the grating detector 603 per unit time and the scale accuracy of the grating ruler 601. For example, within a fixed time interval, a higher number of pulses detected indicates a longer distance traveled by the mover levitation module 200 during that time period, meaning a faster operating speed. By monitoring the speed in real time, the control module 500 can adjust the operating parameters of the magnetic drive module 400 and the levitation gas module 300 in a timely manner to ensure that the mover levitation module 200 operates stably at the predetermined speed.

[0055] The grating detector 603 transmits the detected position, displacement, and velocity-related electrical signals to the control module 500. The control module 500 analyzes and processes this data, comparing it with preset operating parameters. If a deviation is found between the actual operating parameters and the preset values, the control module 500 immediately sends adjustment commands to the magnetic drive module 400 and the suspended gas module 300, achieving closed-loop control of the moving part suspension module 200's operating status.

[0056] Please refer to the above as well. Figures 1 to 6 In one embodiment of this application, the magnetic valve assembly 700 includes a valve stem 701. Each air guide hole 104 has an installation cavity 702 that communicates with the air guide channel 105. A valve plate 703 is fixedly and sealed inside the installation cavity 702. A valve hole 704 is provided on the valve plate 703. The valve stem 701 is slidably and sealed inside the valve hole 704. An air guide groove 705 is provided at the end of the outer side of the valve stem 701 near the air guide channel 105. A sealing disc 706 is fixedly and sealed at the end of the valve stem 701 away from the air guide channel 105. A magnetic ball 707 is fixedly installed at the end of the valve stem 701 near the air guide channel 105. The magnetic ball 707 is magnetically attracted to the moving part suspension module 200.

[0057] During operation, when the moving element suspension module 200 approaches the corresponding magnetic valve assembly 700, the magnetic ball 707 installed on the valve stem 701 near the air guide channel 105 will attract the moving element suspension module 200 due to its magnetic attraction. Under the action of the magnetic force, the magnetic ball 707 drives the valve stem 701 to slide away from the air guide channel 105 along the valve hole 704. As the valve stem 701 moves, the air guide groove 705 on the outer side of the valve stem 701 aligns with the valve hole 704 on the valve plate 703. At this time, the gas in the air guide channel 105 can be smoothly discharged to the air guide hole 104 through the valve hole 704 and the air guide groove 705, thereby forming an air film between the guide rail 103 and the moving element suspension module 200, realizing the suspension of the moving element suspension module 200.

[0058] When the moving part suspension module 200 leaves the corresponding magnetic valve assembly 700, the magnetic force between the magnetic ball 707 and the moving part suspension module 200 disappears. At this time, the pressurized gas in the air guide channel 105 acts on the end of the valve stem 701 near the air guide channel 105, pushing the valve stem 701 to move closer to the air guide channel 105, thus resetting the valve stem 701. As the valve stem 701 resets, the air guide groove 705 and the valve hole 704 are misaligned, the valve closes, gas cannot pass through, and the supply of gas to the corresponding air guide hole 104 stops.

[0059] The magnetic valve assembly 700 controls the opening and closing of the valve through magnetic attraction, enabling precise control of the timing and flow rate of gas discharge. The valve only opens to supply gas and form an air film when the moving element suspension module 200 approaches, and closes when it moves away, avoiding unnecessary gas waste and ensuring a stable air film thickness. This ensures that the moving element suspension module 200 maintains a stable suspension state during operation, effectively improving the stability and reliability of material conveying.

[0060] Please refer to the above as well. Figures 1 to 6 In one embodiment of this application, a limiting ring 708 is fixedly installed on one end of the valve stem 701 near the magnetic ball 707, and a spring 709 is fitted on the valve stem 701, with the spring 709 abutting and connected between the limiting ring 708 and the valve plate 703.

[0061] During operation, when the levitation module 200 approaches the magnetic valve assembly 700, the magnetic ball 707 is attracted by magnetic force, pulling the valve stem 701 away from the air guide channel 105. At this time, the spring 709 fitted on the valve stem 701 is compressed, generating a spring force opposite to the direction of the magnetic force. When the magnetic force is greater than the spring force, the valve stem 701 can move smoothly, aligning the air guide groove 705 with the valve hole 704, opening the valve, and allowing gas to be discharged.

[0062] When the moving part suspension module 200 leaves the magnetic valve assembly 700, the magnetic force between the magnetic ball 707 and the moving part suspension module 200 disappears. At this time, the compressed spring 709 begins to release its elastic force, pushing the valve stem 701 towards the gas guide channel 105, thus resetting the valve stem 701 and closing the valve. The elastic force of the spring 709 ensures that the valve stem 701 can quickly and accurately return to its initial position, preventing gas leakage.

[0063] A limiting ring 708, fixedly installed on the valve stem 701 near the magnetic ball 707, restricts the movement range of the valve stem 701. When the valve stem 701 moves under magnetic force, the limiting ring 708 prevents the valve stem 701 from moving excessively, avoiding the valve stem 701 from detaching from the valve hole 704 and colliding with other components, thus ensuring the structural integrity and operational stability of the magnetic valve assembly 700.

[0064] Please refer to the above as well. Figures 1 to 6 In one embodiment of this application, a plurality of buffer columns 710 are fixedly installed on the end of the sealing disc 706 away from the valve stem 701, corresponding to the inner end face of the mounting cavity 702. The buffer columns 710 are arranged in a centrally symmetrical manner with respect to the center of the air guide hole 104.

[0065] During operation, when the moving part suspension module 200 approaches the magnetic valve assembly 700, the magnetic ball 707 is attracted by magnetic force, which will push the valve stem 701 to move away from the air guide channel 105.

[0066] At this moment, just as the sealing disc 706 is about to contact the inner end face of the mounting cavity 702, the buffer column 710, fixedly mounted on the sealing disc 706, will also contact the inner end face of the mounting cavity 702. On one hand, the buffer column 710 has good elasticity and cushioning performance; it deforms when compressed, absorbing the impact force generated by the collision between the sealing disc 706 and the inner end face of the mounting cavity 702, slowing down the movement speed of the sealing disc 706, and reducing the vibration generated by the collision. On the other hand, the buffer column 710 can form an effective airflow channel between the outer end of the sealing disc 706 and the inner end face of the mounting cavity 702, preventing the valve stem 701 from moving excessively and causing a seal to form between the outer end of the sealing disc 706 and the inner end face of the mounting cavity 702.

[0067] Furthermore, the multiple buffer pillars 710 are arranged symmetrically around the center of the air guide hole 104, ensuring that the buffering force on the sealing disc 706 is evenly distributed in all directions when it contacts the inner end face of the mounting cavity 702. This prevents the valve stem 701 from tilting or shifting due to uneven force, thus maintaining the stability of the valve stem 701 during operation.

[0068] Please refer to the above as well. Figures 1 to 6 In one specific embodiment of this application, the valve stem 701 and the magnetic ball 707 are integrally formed from iron material. Iron material has good magnetic conductivity, which can better respond to the magnetic field in the magnetic valve assembly, ensuring that the magnetic ball 707 moves accurately under the action of magnetic force, realizing effective control of components such as valve hole 704, and ensuring the normal operation of the valve.

[0069] The implementation principle of a magnetic levitation flexible transport system according to an embodiment of this application is as follows:

[0070] Operators input control parameters and commands through control panel 502, and display 503 shows the system operating status in real time. Control module 500 coordinates and controls the operation of the entire conveying system according to preset programs and received signals. Air pump 301 is started to draw air, which is sent to pressure stabilizing tank 303 through output pipe 302 for pressure stabilization. Solenoid valve 304 regulates gas flow and pressure according to the command of control module 500. Gas enters air guide channel 105 through positive pressure pipe 305, connecting pipe 108, second connecting hole 107, and first connecting hole 106.

[0071] When the levitation module 200 moves along the guide rail 103, the first magnetic body 204 on the slider 201 approaches the magnetic valve assembly 700. The magnetic ball 707 is attracted by the magnetic force, causing the valve stem 701 to move against the elastic force of the spring 709, aligning the air guide groove 705 with the valve hole 704. Gas is discharged from the air guide hole 104, forming an air film between the guide rail 103 and the slider 201, thus levitizing the levitation module 200. At the same time, the control module 500 supplies power to the electromagnetic component 403 to generate a magnetic field, which interacts with the second magnetic body 401, driving the levitation module 200 to move along the guide rail 103.

[0072] The grating ruler 601 moves with the moving part suspension module 200. The grating detector 603 detects the scale change and generates a pulse signal, which is fed back to the control module 500 to calculate the position and speed of the moving part suspension module 200. If there is a deviation from the preset parameters, the control module 500 adjusts the current of the electromagnetic component 403, changes the magnetic field strength and direction, and adjusts the opening of the solenoid valve 304 to control the gas pressure, ensuring that the moving part suspension module 200 operates stably along the predetermined path and speed. After the moving part suspension module 200 leaves the magnetic suction valve assembly 700, the magnetic force disappears, the spring 709 pushes the valve stem 701 to reset and close the valve, and the buffer column 710 reduces the impact of the sealing disc 706, ensuring the stable operation of the magnetic suction valve assembly 700. This achieves high-precision and stable material conveying, meeting the needs of intelligent and precise modern industrial production.

[0073] In summary, this magnetic levitation flexible conveying system achieves high-precision and stable material conveying through the coordinated operation of functional modules such as levitation, driving, monitoring and control, meeting the needs of intelligent and precise modern industrial production.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
