Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly relates to a magnetic levitation flexible conveying system. Background Art

[0002] Under the development trend of the intelligence and precision of 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 conveying systems rely on single magnetic force control. When operating at high speeds or under load changes, it is difficult to accurately control the position and movement trajectory of the levitated body, resulting in deviation in material conveying, insufficient conveying accuracy, and difficulty in meeting the requirements of high-precision production. At the same time, although the magnetic levitation system realizes non-contact driving, the structures for auxiliary guiding and supporting still have mechanical contacts. After long-term operation, serious wear will occur, which not only shortens the equipment life, but also increases the maintenance cost and downtime. Moreover, after the structures for auxiliary guiding and supporting are worn, the magnetic levitation flexible conveying system is prone to fluctuations in the levitation height and deviation of the movement trajectory. Especially during long-term continuous operation, the stability problem is more prominent, seriously affecting the reliability of material conveying and being unfavorable for effectively ensuring the stability and conveying efficiency of the system.

[0004] Therefore, how to develop a magnetic levitation flexible conveying system that takes into account high-precision control, low wear, and high stability, realizes precise positioning and trajectory control of the levitated body under complex working conditions, and at the same time optimizes the structures for auxiliary guiding and supporting to eliminate mechanical contact losses, and improves the reliability and conveying efficiency of the system during long-term continuous operation is an urgent problem to be solved by those skilled in the art.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0029] The embodiment of the present application discloses a magnetic levitation flexible conveying system.

[0030] Please refer to Figures 1 to 6 , in an embodiment of the present application, a magnetic levitation flexible conveying system includes a stator guide rail module 100, a mover levitation module 200 is slidably connected to the stator guide rail module 100, a levitation gas module 300 is connected to the stator guide rail module 100 corresponding to the mover levitation module 200, a magnetic force driving module 400 is arranged between the stator guide rail module 100 and the mover levitation module 200, the levitation gas module 300 and the magnetic force driving module 400 are electrically connected to a control module 500, and the control module 500 is electrically connected to a detection module 600; the stator guide rail module 100 includes a mounting base 101, a mounting bracket 102 is fixedly installed on the mounting base 101, a guide rail 103 is fixedly installed on the mounting bracket 102, the mover levitation module 200 is installed on the guide rail 103, uniformly distributed air guide holes 104 are formed in the guide rail 103 along its length direction towards the mover levitation module 200, magnetic valve assemblies 700 are hermetically installed inside the air guide holes 104, the mover levitation module 200 is magnetically driven and connected to the magnetic valve assemblies 700, an air guide channel 105 communicating with all the air guide holes 104 is formed inside the guide rail 103, and the air guide channel 105 is connected to the levitation gas module 300.

[0031] During the working process, the suspension gas module 300 generates high-pressure gas, and the gas enters each air guide hole 104 on the guide rail 103 through the air guide channel 105. The mover suspension module 200 is magnetically driven and connected to the magnetic valve assembly 700. When the mover suspension module 200 approaches the corresponding magnetic valve assembly 700, the magnetic valve assembly 700 is controlled to open through the magnetic attraction principle, so that the high-pressure gas is discharged from the air guide hole 104, and a uniform air film is formed between the guide rail 103 and the mover suspension module 200, enabling the mover suspension module 200 to be suspended above the guide rail 103 and effectively reducing the frictional resistance between the two.

[0032] Under the regulation 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 mover suspension module 200 to drive it to move along the length direction of the guide rail 103. The control module 500 precisely controls the magnetic field change of the magnetic drive module 400 according to the preset conveying path and speed requirements to achieve the flexible movement of the mover suspension module 200.

[0033] The detection module 600 real-time detects the position state of the mover suspension module 200 and feeds back the position state to the control module 500 in the form of an electrical signal. The control module 500 makes real-time adjustments to the gas pressure of the suspension gas module 300, the magnetic field intensity and direction of the magnetic drive module 400 according to the feedback signal to ensure that the mover suspension module 200 can operate stably according to the predetermined path and speed, and at the same time ensure the reliability of the suspension effect.

[0034] Please also refer to Figures 1 to 6 , in an embodiment of the present application, a first connection hole 106 communicating with the air guide channel 105 is opened on the guide rail 103, a second connection hole 107 hermetically communicating with the first connection hole 106 is opened on the mounting bracket 102, a connecting pipe 108 communicating with the second connection hole 107 is fixedly and hermetically installed on the mounting bracket 102, and one end of the connecting pipe 108 away from the mounting bracket 102 is connected to the suspension gas module 300.

[0035] During operation, the gas generated by the suspension gas module 300 is transmitted through the connecting pipe 108. The connecting pipe 108 is sealed and connected 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 guide channel 105 inside the guide rail 103 through the first connecting hole 106 that is sealed and connected to the second connecting hole 107. Finally, the gas is discharged from the air guide channel 105 through the evenly distributed air guide holes 104, and an air film is formed between the guide rail 103 and the mover suspension module 200, so as to realize the suspension of the mover suspension module 200. A sealed connection method is adopted between the first connecting hole 106 and the second connecting hole 107, and between the second connecting hole 107 and the connecting pipe 108. This sealing design ensures that the gas will not leak during the transmission process, and ensures that the gas can enter the air guide channel 105 completely. A stable gas supply is the key to forming a stable air film, and the sealed connection effectively guarantees the stability of the suspension effect of the mover suspension module 200.

[0036] Please refer to Figures 1 to 6 In one embodiment of the present application, the movable suspension module 200 includes a slider 201, which is slidably connected to the guide rail 103. A slide groove 202 is provided 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 slide groove 202 and the outer surface of the guide rail 103. An installation groove 203 is provided 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, and 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.

[0037] During operation, the slide groove 202 on the slider 201 is adapted to the cross-sectional shape of the guide rail 103 to achieve a sliding connection. When the suspended gas module 300 is working, the gas is discharged through the gas guide channel 105 and the gas guide hole 104, and an air film is formed between the guide rail 103 and the slider 201. Due to the fitting design of the slide groove 202 and the guide rail 103, the air film can be better constrained, so that the slider 201 is 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 with the magnetic valve assembly 700 in the gas guide hole 104. When the motor suspension module 200 is close to the corresponding magnetic valve assembly 700, the magnetic valve assembly 700 will open under the magnetic force of the first magnetic body 204, so that the magnetic valve assembly 700 in other gas guide holes 104 on the guide rail 103 can be opened to cause air leakage, thereby ensuring the suspension effect of the suspended gas module 300 on the motor suspension module 200.

[0038] Please refer to Figures 1 to 6, in an embodiment of the present application, the suspension gas module 300 includes an air pump 301. The output end of the air pump 301 is fixedly and sealingly connected to an output pipe 302. The end of the output pipe 302 away from the air pump 301 is fixedly and sealingly connected to a pressure stabilizing tank 303. An electric control valve 304 is fixedly and sealingly connected to the pressure stabilizing tank 303. A positive pressure pipe 305 is sealingly connected to the electric control valve 304. The positive pressure pipe 305 is sealingly communicated with the air guiding channel 105.

[0039] During the working process, after the air pump 301 is started, it extracts air, and these gases are output through the output pipe 302 fixedly and sealingly connected to the output end of the air pump 301. The output pipe 302 transports the gases to the pressure stabilizing tank 303, and the pressure stabilizing tank 303 plays a role in buffering and stabilizing the gas pressure. The electric control valve 304 connected to the pressure stabilizing tank 303 can adjust the opening degree to control the output amount of the gas. Under the control of the control module 500, the electric control valve 304 precisely regulates the flow rate and pressure of the gas. According to the actual operation requirements of the mover suspension module 200, the regulated gas enters the air guiding channel 105 of the guide rail 103 through the positive pressure pipe 305 and finally discharges from the air guiding hole 104, forming a stable air film between the guide rail 103 and the mover suspension module 200 to achieve the suspension and stable operation of the mover suspension module 200.

[0040] Please refer to Figures 1 to 6 , in an embodiment of the present 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 electromagnetic members 403 are fixedly installed on one side surface of the mounting bracket 102 at equal intervals. The electromagnetic members 403 are arranged along the length direction of the guide rail 103, and the electromagnetic members 403 are correspondingly arranged with the second magnetic body 401.

[0041] During the working process, the control module 500 supplies power to the electromagnetic members 403 equally spaced on the side surface of the mounting bracket 102. After the electromagnetic members 403 are energized, they generate a magnetic field. A magnetic circuit is formed between the electromagnetic members 403 and the second magnetic body 401. By controlling the magnitude and direction of the current of the electromagnetic members 403, the intensity and direction of the generated magnetic field can be adjusted. When the magnetic field generated by the electromagnetic members 403 interacts with the second magnetic body 401, according to the principle of like poles repelling and opposite poles attracting, a magnetic force is generated. Under the action of the magnetic force, the second magnetic body 401 drives the connecting seat 206 and the entire mover suspension module 200 to move along the length direction of the guide rail 103. The control module 500 continuously monitors the information such as the position and speed of the mover suspension module 200 fed back by the detection module 600, and adjusts the current parameters of the electromagnetic members 403 in real time, thereby changing the magnetic field characteristics to achieve precise control of the movement direction, speed and position of the mover suspension module 200.

[0042] Please refer to Figures 1 to 6, in a specific embodiment of the present application, both the first magnetic body 204 and the second magnetic body 401 are made of permanent magnetic materials, such as neodymium iron boron permanent magnets (NdFeB). Neodymium iron boron permanent magnets (NdFeB) are the most magnetic among currently commercialized permanent magnetic materials, which can provide a strong magnetic field force and are suitable for scenarios where the drive module requires high thrust. With the same magnetic force, they have a smaller volume, which helps to miniaturize and lighten the mover suspension module. In the magnetic force drive module 400, neodymium iron boron permanent magnets can enable the electromagnetic component 403 to generate sufficient driving force with a smaller current, reducing energy consumption.

[0043] It can be understood that in other embodiments of the present application, the first magnetic body 204 and the second magnetic body 401 can also use 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 is beneficial to extending the service life.

[0044] Please refer to Figures 1 to 6 , in an embodiment of the present application, the control module 500 includes a controller 501. The controller 501 is electrically connected to the suspension gas module 300, the magnetic force drive module 400, and the detection module 600. The controller 501 is electrically connected to a control panel 502 and a display 503.

[0045] The detection module 600 real-time detects the position state of the mover suspension module 200 and feeds back the position state to the control module 500 in the form of an electrical signal. The control module 500 adjusts the gas pressure of the suspension gas module 300, the magnetic field strength and direction of the magnetic force drive module 400 in real time according to the feedback signal, ensuring that the mover suspension module 200 can operate stably according to the predetermined path and speed, and at the same time ensuring the reliability of the suspension effect.

[0046] During the working process, the detection module 600 real-time monitors the position and speed signals of the mover suspension module 200 and feeds back the position and speed signals to the controller 501. As the core of the control module 500, the controller 501 analyzes and processes the received data to determine whether the current state of the system meets the preset parameter requirements.

[0047] The operator can input various operation instructions to the controller 501 through the control panel 502, such as adjusting the running speed, starting or stopping the system. After receiving the instructions, the controller 501 makes corresponding adjustments to the system. At the same time, the display 503 real-time displays the running parameters, working status, and fault information of the system, etc., facilitating the operator to intuitively understand the running situation of the system, discover problems in time and handle them.

[0048] According to the data analysis results, the controller 501 combines the preset control program and the instructions input by the operator through the control panel 502, and sends control signals to the suspension gas module 300 and the magnetic drive module 400.

[0049] For example, when it is detected that the speed of the mover suspension module 200 is lower than the set value, the controller 501 sends an instruction to the magnetic drive module 400 to increase the current of the electromagnetic component 403 and enhance the magnetic force, thereby increasing the running speed of the mover suspension module 200 to maintain a stable working state.

[0050] Please refer to Figures 1 to 6 In an embodiment of the present application, the detection module 600 includes a grating scale 601. A second mounting plate 602 is fixedly installed on one side of the connecting seat 206, and the grating scale 601 is fixedly installed on the second mounting plate 602. A number of equally spaced grating detectors 603 are fixedly installed on one side surface 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 arranged corresponding to the grating scale 601.

[0051] During the working process, the grating scale 601 is fixedly installed on the second mounting plate 602 of the connecting seat 206 and moves together with the mover suspension module 200. The equally spaced grating detectors 603 on the side surface of the mounting bracket 102 are arranged along the length direction of the guide rail 103 and correspond to the grating scale 601. When the mover suspension module 200 moves on the guide rail 103, the grating scale 601 moves past each grating detector 603. Fine scales are engraved on the grating scale 601. The grating detector 603 converts the physical displacement into an electrical signal by detecting the change in the scale of the grating scale 601. Every time a specific scale is passed, the grating detector 603 generates a pulse signal. By counting and processing the pulse signals, the position and displacement of the mover suspension module 200 can be accurately calculated.

[0052] The control module 500 calculates the running speed of the mover suspension module 200 according to the number of pulses generated by the grating detector 603 within a unit time, in combination with the scale accuracy of the grating scale 601. For example, within a fixed time interval, if the number of detected pulses is more, it means that the mover suspension module 200 moves a longer distance during this time period, that is, the running speed is faster. By monitoring the speed in real time, the control module 500 can timely adjust the working parameters of the magnetic drive module 400 and the suspension gas module 300 to ensure that the mover suspension module 200 operates stably at a predetermined speed.

[0053] The grating detector 603 transmits the detected position, displacement, speed and other related electrical signals to the control module 500. The control module 500 analyzes and processes these data and compares them with the preset operating parameters. If it is found that the actual operating parameters deviate from the preset values, the control module 500 will immediately send adjustment instructions to the magnetic drive module 400 and the suspension gas module 300 to achieve closed-loop control of the operating state of the mover suspension module 200.

[0054] Please refer to Figures 1 to 6 In one embodiment of the present application, the magnetic valve assembly 700 includes a valve stem 701, each air guide hole 104 is provided with an installation cavity 702 connected to the air guide channel 105, the installation cavity 702 is fixedly and sealedly connected with a valve plate 703, the valve plate 703 is provided with a valve hole 704, the valve stem 701 is sealingly and slidably connected inside the valve hole 704, an air guide groove 705 is provided on the outer side of the valve stem 701 at one end close to the air guide channel 105, a sealing disk 706 is fixedly and sealedly connected to the end of the valve stem 701 away from the air guide channel 105, and a magnetic ball 707 is fixedly installed on the end of the valve stem 701 close to the air guide channel 105, and the magnetic ball 707 is magnetically attracted to the mover suspension module 200.

[0055] During operation, when the motor suspension module 200 is close to the corresponding magnetic valve assembly 700, the magnetic ball 707 installed at one end of the valve stem 701 close to the air guide channel 105 will generate attraction due to magnetic attraction with the motor suspension module 200. Under the action of magnetic force, the magnetic ball 707 drives the valve stem 701 to slide along the valve hole 704 in the direction away from the air guide channel 105. As the valve stem 701 moves, the air guide groove 705 on the outer side of the valve stem 701 is aligned 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 motor suspension module 200, thereby realizing the suspension of the motor suspension module 200.

[0056] When the motor suspension module 200 leaves the corresponding magnetic valve assembly 700, the magnetic force between the magnetic ball 707 and the motor suspension module 200 disappears. At this time, the pressure gas in the air guide channel 105 will act on the end of the valve stem 701 close to the air guide channel 105, pushing the valve stem 701 to move in the direction close to the air guide channel 105, so that the valve stem 701 is reset. As the valve stem 701 is reset, the air guide groove 705 and the valve hole 704 are offset, the valve is closed, the gas cannot pass, and the gas supply to the corresponding air guide hole 104 stops.

[0057] The magnetic valve assembly 700 controls the opening and closing of the valve through magnetic attraction, and can accurately control the gas discharge timing and flow rate. The valve only supplies gas to form an air film when the mover suspension module 200 approaches, and closes when it leaves, avoiding unnecessary gas waste. At the same time, it ensures the stability of the air film thickness, ensuring that the mover suspension module 200 always maintains a stable suspension state during operation, effectively improving the stability and reliability of material transportation.

[0058] Please also refer to Figures 1 to 6 In an embodiment of the present application, a limit ring 708 is fixedly installed at one end of the valve stem 701 close to the magnetic attraction ball 707. A spring 709 is sleeved on the valve stem 701, and the spring 709 is abutted and connected between the limit ring 708 and the valve plate 703.

[0059] During the working process, when the mover suspension module 200 approaches the magnetic valve assembly 700, the magnetic attraction ball 707 is attracted by the magnetic force and pulls the valve stem 701 to move in a direction away from the air guide channel 105. At this time, the spring 709 sleeved on the valve stem 701 is compressed, and the spring 709 generates an elastic force opposite to the direction of the magnetic force. When the magnetic force is greater than the elastic force of the spring, the valve stem 701 can move smoothly, aligning the air guide groove 705 with the valve hole 704, opening the valve, and allowing the gas to be discharged.

[0060] After the mover suspension module 200 leaves the magnetic valve assembly 700, the magnetic force between the magnetic attraction ball 707 and the mover suspension module 200 disappears. At this time, the compressed spring 709 begins to release the elastic force, pushing the valve stem 701 to move in a direction close to the air guide channel 105, 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 the initial position, preventing gas leakage.

[0061] The limit ring 708 fixedly installed at one end of the valve stem 701 close to the magnetic attraction ball 707 restricts the movement range of the valve stem 701. When the valve stem 701 moves under the action of the magnetic force, the limit ring 708 can prevent the valve stem 701 from moving excessively, avoiding the valve stem 701 from disengaging from the valve hole 704 and colliding with other components, ensuring the structural integrity and working stability of the magnetic valve assembly 700.

[0062] Please also refer to Figures 1 to 6 In an embodiment of the present application, a plurality of buffer columns 710 are fixedly installed at the end of the sealing disk 706 away from the valve stem 701 corresponding to the inner end face of the installation cavity 702. The buffer columns 710 are arranged in central symmetry with the center of the air guide hole 104.

[0063] During the operation of the magnetic valve assembly 700, when the mover suspension module 200 approaches the magnetic valve assembly 700, the magnetic ball 707 is attracted by the magnetic force and will push the valve stem 701 to move away from the gas guide channel 105.

[0064] At this time, when the sealing disk 706 is about to contact the inner end face of the installation cavity 702, the buffer column 710 fixedly installed on the sealing disk 706 will contact the inner end face of the installation cavity 702. On the one hand, the buffer column 710 has good elasticity and buffering performance and will deform when being squeezed, absorbing the impact force generated by the collision between the sealing disk 706 and the inner end face of the installation cavity 702, slowing down the movement speed of the sealing disk 706, and reducing the vibration generated by the collision. On the other hand, the buffer column 710 can form an effective air flow channel between the outer end of the sealing disk 706 and the inner end face of the installation cavity 702, preventing the outer end of the sealing disk 706 from forming a seal with the inner end face of the installation cavity 702 due to excessive movement of the valve stem 701.

[0065] Moreover, multiple buffer columns 710 are arranged in central symmetry with the center of the air guide hole 104, so that when the sealing disk 706 contacts the inner end face of the installation cavity 702, the buffer forces received in all directions are evenly distributed. This avoids the valve stem 701 from tilting or shifting due to uneven force, enabling the valve stem 701 to remain stable during operation.

[0066] Please also refer to Figures 1 to 6 , in a specific embodiment of the present application, the valve stem 701 and the magnetic ball 707 are integrally formed of iron material. The iron material has good magnetic conductivity and can better respond to the magnetic field in the magnetic valve assembly, ensuring the accurate movement of the magnetic ball 707 under the action of the magnetic force, realizing the effective control of components such as the valve hole 704, and ensuring the normal operation of the valve.

[0067] The implementation principle of a magnetic levitation flexible conveying system in an embodiment of the present application is as follows: The operator inputs control parameters and instructions through the control panel 502, and the display 503 displays the operating status of the system in real time. The control module 500 coordinates and controls the operation of the entire conveying system according to the preset program and the received signals. The air pump 301 is started to extract air, which is sent into the pressure stabilizing tank 303 through the output pipe 302 for pressure stabilization. The electromagnetic valve 304 regulates the gas flow and pressure according to the instructions of the control module 500, and the gas enters the gas guide channel 105 through the positive pressure pipe 305, the connecting pipe 108, the second connecting hole 107, and the first connecting hole 106.

[0068] When the mover suspension module 200 moves along the guide rail 103, the first magnet 204 on the slider 201 approaches the magnetic valve assembly 700. The magnetic ball 707 is attracted by the magnetic force and drives 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. The gas is discharged from the air guide hole 104, forming an air film between the guide rail 103 and the slider 201 to achieve the suspension of the mover suspension 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 magnet 401 to drive the mover suspension module 200 to move along the guide rail 103.

[0069] The grating scale 601 moves with the mover suspension module 200. The grating detector 603 detects the change in its scale to generate a pulse signal, which is fed back to the control module 500 to calculate the position and speed of the mover 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 electro-control valve 304 to control the gas pressure to ensure that the mover suspension module 200 operates stably along the predetermined path and speed. After the mover suspension module 200 leaves the magnetic valve assembly 700, the magnetic force disappears, and the spring 709 pushes the valve stem 701 to reset and close the valve. The buffer column 710 reduces the collision impact of the sealing disc 706 to ensure the stable operation of the magnetic valve assembly 700. Thereby, the high-precision and stable conveying of materials is realized, meeting the requirements of intelligent and precise modern industrial production.

[0070] In summary, the magnetic levitation flexible conveying system realizes the high-precision and stable conveying of materials through the collaborative work of functional modules such as suspension, drive, monitoring, and control, meeting the requirements of intelligent and precise modern industrial production.

[0071] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
