Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically to a magnetic levitation system and production line. Background Technology

[0002] Among related technologies, magnetic levitation technology is a technique that uses magnetic force to overcome gravity and levitate objects. Currently, there are three main types: electromagnetic levitation, superconducting antimagnetic levitation, and permanent magnet levitation. Magnetic levitation logistics lines rely on non-contact transmission, but dust and ink particles easily adhere to the track, interfering with the stability of the magnetic field and reducing transmission accuracy. Therefore, related technologies use dust covers fixed to the track to prevent dust and other impurities from adhering to the track, which is detrimental to track maintenance and repair. Utility Model Content

[0003] The embodiments of this utility model provide a magnetic levitation system and production line, which can improve the technical problem in related technologies that dust and ink splatter easily adhere to the surface of the track or magnetic levitation stator control board, interfering with the stability of the magnetic field and reducing the transmission accuracy.

[0004] In a first aspect, embodiments of the present invention provide a magnetic levitation system, comprising:

[0005] A stator assembly, wherein the stator assembly is provided with a track;

[0006] A mover assembly, magnetically connected to the stator assembly, for being driven by the stator assembly to move along the track; and,

[0007] A dust cover, which is detachably connected to the stator assembly, and at least a portion of the dust cover is disposed between the track and the mover assembly.

[0008] In one embodiment, the dust cover includes:

[0009] A cover, the cover including a first surface facing the stator assembly;

[0010] A connector disposed on the first surface for detachable connection with the stator assembly.

[0011] Therefore, the cover can effectively cover the upper space of the stator assembly, thus forming a physical barrier for the stator assembly and preventing impurities such as dust and ink from entering the track area, thereby avoiding these impurities from interfering with the stability of the magnetic field and ensuring the transmission accuracy of the magnetic levitation system.

[0012] The connector is located on the first surface of the cover, which allows the dust cover to be detachably connected to the stator assembly. This allows for quick removal of the dust cover when the stator assembly needs maintenance, and also facilitates the installation and replacement of the dust cover. This improves the convenience and flexibility of system maintenance, and further enhances the practicality and reliability of the magnetic levitation system.

[0013] In one embodiment, the stator assembly further includes:

[0014] A housing, wherein the housing is detachably connected to the connector to form a cavity between the housing and the connector; and,

[0015] A coil is disposed within the cavity and is used to drive the mover assembly to move along the track.

[0016] Thus, the detachable connection between the housing and the connector not only facilitates the installation and removal of the dust cover, but also provides convenience for the assembly and maintenance of the coil.

[0017] Furthermore, by forming a cavity between the housing and the connector, a stable and protected installation space is provided for the coil, ensuring that the coil is not disturbed by the external environment during operation, such as the intrusion of dust, moisture or other impurities, thereby extending the service life of the coil and ensuring its performance stability.

[0018] Meanwhile, the coil is placed inside the cavity to drive the mover assembly to move along the track, making the generation and conduction of the magnetic field more concentrated and efficient, further improving the driving performance and overall operating efficiency of the magnetic levitation system.

[0019] In one embodiment, the mover assembly includes a body and a mating portion connected to each other, the body being disposed on the outside of the dust cover and the mating portion being disposed on the inside of the dust cover for being driven by the coil.

[0020] The main body is located on the outside of the dust cover, which not only provides stable structural support for the moving part assembly, but also prevents it from coming into contact with dust or impurities on the surface of the dust cover, thereby ensuring that the external structure of the moving part assembly is not contaminated or damaged.

[0021] The mating part is located inside the dust cover and interacts directly with the magnetic field generated by the coil, thereby achieving a highly efficient driving effect.

[0022] Furthermore, in practical use, in order to ensure the driving effect of the magnetic levitation system, a coil is also set inside the mating part. Therefore, placing the mating part inside the dust cover can also protect the mating part, prevent dust or impurities from falling into the mating part, and ensure that the magnetic connection between the coils is not disturbed, thereby ensuring the stability of the magnetic field and ensuring the transmission accuracy.

[0023] In one embodiment, the moving part assembly further includes a slider disposed on the mating portion for movement along the track.

[0024] Thus, the slider configuration enables the mover assembly to achieve smoother and more precise motion control during operation, further improving the system's positioning accuracy and repeatability, and enabling it to better meet the requirements of high-precision and high-efficiency magnetic levitation transmission.

[0025] In one embodiment, the mating part is provided with a clearance groove, the housing part is disposed in the clearance groove, and the inner wall of the clearance groove is provided with a plurality of heat dissipation notches.

[0026] Since the magnetic levitation system generates heat during operation, the heat dissipation gap can effectively promote air circulation in the clearance slot, accelerate heat dissipation, prevent local overheating from damaging the coil, housing or other components, and extend the service life of the magnetic levitation system.

[0027] In one embodiment, the housing is provided with a limiting groove, and the connector is provided with a limiting plate corresponding to the limiting groove, the limiting plate being engaged with the limiting groove.

[0028] Thus, the precise positioning of the dust cover during installation is achieved through the snap-fit ​​between the limiting plate and the limiting groove, effectively preventing the dust cover from shifting or loosening during operation and ensuring that it is always in the best protective position. This continuously and effectively blocks dust, ink splatter, and other impurities from entering the track area, ensuring the stability of the magnetic field and the transmission accuracy of the system.

[0029] In addition, the locking mechanism between the limiting plate and the limiting slot simplifies the installation and removal of the dust cover, making maintenance operations more convenient and efficient, and further improving the maintainability and practicality of the magnetic levitation system.

[0030] In one embodiment, the dust cover further includes a support portion protruding from the first surface of the cover body, and the connector is connected to the support portion such that a clearance space is formed between the connector and the cover body to allow at least a portion of the moving part assembly to pass.

[0031] In this way, interference between the dust cover and the moving part can be effectively avoided, allowing the moving part to pass smoothly during operation. This reduces the stability of the interfering magnetic field and ensures transmission accuracy without affecting magnetic levitation transportation, while also ensuring the motion accuracy and stability of the system.

[0032] Meanwhile, the design of the clearance space also provides greater freedom of movement for the moving part components, reducing the risk of friction or collision caused by space constraints, and further improving the operating efficiency and reliability of the magnetic levitation system.

[0033] In one embodiment, the support portion is provided with weight-reducing holes.

[0034] In this way, by opening weight-reducing holes in the support, the overall weight of the dust cover is effectively reduced, thereby reducing the load on the magnetic levitation system. The setting of weight-reducing holes also optimizes the use of materials, reduces manufacturing costs, and makes the structure of the dust cover lighter, making it easier to install and disassemble.

[0035] In addition, the weight-reducing holes can also improve the heat dissipation performance of the support to a certain extent, which helps to dissipate heat during system operation and further enhances the stability and reliability of the magnetic levitation system.

[0036] It is understood that in this embodiment, the weight reduction holes extend along the length of the dust cover.

[0037] In one embodiment, the cover includes:

[0038] A first connecting plate, wherein the side of the first connecting plate facing the stator assembly is the first surface; and,

[0039] At least two second connecting plates, wherein the first connecting plate has a second connecting plate protruding on each side along the width direction, and the connector and the support are both located between the two second connecting plates.

[0040] Thus, the side of the first connecting plate facing the stator assembly serves as the first surface for mounting connectors and supports, ensuring a stable connection between the dust cover and the stator assembly. The two second connecting plates protrude from both sides of the first connecting plate along the width direction, forming a semi-enclosed structure. This not only enhances the overall rigidity and structural strength of the cover but also effectively prevents external impurities from entering the track area from the side, further improving the dustproof effect.

[0041] Meanwhile, the connector and support are located between the two second connecting plates, making the dust cover structure more compact and the installation more stable. It also facilitates the smooth operation of the moving part assembly inside the dust cover and avoids interference.

[0042] In one embodiment, the first connecting plate further includes a second surface facing away from the first surface, and the second surface is provided with a weight reduction groove.

[0043] By creating weight-reducing grooves on the second surface, the overall weight of the cover is effectively reduced, thereby reducing the load on the magnetic levitation system and improving the system's operating efficiency and dynamic response performance.

[0044] Meanwhile, the design of the weight-reducing groove optimizes the use of materials, reduces manufacturing costs, and makes the dust cover structure lighter, making it easier to install and disassemble.

[0045] In addition, the weight reduction groove can also enhance the heat dissipation capacity of the cover to a certain extent, which helps to dissipate heat quickly during system operation and further improves the stability and reliability of the magnetic levitation system.

[0046] Secondly, embodiments of this utility model provide a production line including the magnetic levitation system described in the foregoing embodiments.

[0047] The beneficial effects of the embodiments of this utility model are as follows:

[0048] In an embodiment of this utility model, a portion of the dust cover is disposed between the track and the mover assembly. Therefore, the dust cover can protect the track, thereby preventing dust or ink from falling onto the stator assembly, preventing dust or ink from interfering with the stability of the magnetic field, and ensuring the transmission accuracy of the magnetic levitation system.

[0049] In addition, since the dust cover is detachably connected to the stator assembly, it can be directly removed when the stator assembly needs maintenance, which facilitates maintenance. Attached Figure Description

[0063] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0064] Reference Figure 1 and Figure 2 As shown, the first aspect of this utility model provides a magnetic levitation system 1, which includes a stator assembly 11, a mover assembly 12 and a dust cover 13. The stator assembly 11 is provided with a track 111. The mover assembly 12 is magnetically connected to the stator assembly 11 for moving along the track 111 under the drive of the stator assembly 11. The dust cover 13 is detachably connected to the stator assembly 11, and at least a portion of the dust cover 13 is disposed between the track 111 and the mover assembly 12.

[0065] In an embodiment of this utility model, a portion of the dust cover 13 is disposed between the track 111 and the mover assembly 12. Therefore, the dust cover 13 can protect the track 111, thereby preventing dust or ink from falling onto the stator assembly 11, preventing dust or ink from interfering with the stability of the magnetic field, and ensuring the transmission accuracy of the magnetic levitation system 1.

[0066] Furthermore, since the dust cover 13 is detachably connected to the stator assembly 11, the dust cover 13 can be directly removed when the stator assembly 11 needs maintenance, which facilitates maintenance.

[0067] It should also be noted that, in order to ensure the dustproof effect of the dust cover 13 on the stator assembly 11, in this embodiment, the length of the dust cover 13 is not less than the maximum length of the stator assembly 11.

[0068] In some embodiments, refer to Figure 3 As shown, the dust cover 13 includes a cover body 131 and a connector 132. The cover body 131 includes a first surface 1311 facing the stator assembly 11; and the connector 132 is disposed on the first surface 1311 for detachable connection to the stator assembly 11.

[0069] Therefore, the cover 131 can effectively cover the upper space of the stator assembly 11, thereby forming a physical barrier for the stator assembly 11 and preventing dust, ink splatter and other impurities from entering the track 111 area, thereby avoiding these impurities from interfering with the stability of the magnetic field and ensuring the transmission accuracy of the magnetic levitation system 1.

[0070] The connector 132 is disposed on the first surface 1311 of the cover 131, which enables the dust cover 13 to be detachably connected to the stator assembly 11. When the stator assembly 11 needs to be maintained, the dust cover 13 can be quickly disassembled. It also facilitates the installation and replacement of the dust cover 13, improves the maintenance convenience and flexibility of the system, and further enhances the practicality and reliability of the magnetic levitation system 1.

[0071] In some embodiments, refer to Figure 4 As shown, the stator assembly 11 also includes a housing 112 and a coil. The housing 112 is detachably connected to the connector 132 to form a cavity 113 between the housing 112 and the connector 132. The coil is disposed in the cavity 113 and is used to drive the actuator assembly 12 to move along the track 111.

[0072] Thus, the detachable connection between the housing 112 and the connector 132 not only facilitates the installation and removal of the dust cover 13, but also provides convenience for the assembly and maintenance of the coil.

[0073] Furthermore, by forming a cavity 113 between the housing 112 and the connector 132, a stable and protected installation space is provided for the coil, ensuring that the coil is protected from external environmental interference during operation, such as the intrusion of dust, moisture or other impurities, thereby extending the service life of the coil and ensuring its performance stability.

[0074] Meanwhile, the coil is placed in the cavity 113 to drive the mover assembly 12 to move along the track 111, making the generation and conduction of the magnetic field more concentrated and efficient, further improving the driving performance and overall operating efficiency of the magnetic levitation system 1.

[0075] In some embodiments, refer to Figure 5 As shown, the mover assembly 12 includes a body 121 and a mating part 122 connected to each other. The body 121 is disposed on the outside of the dust cover 13, and the mating part 122 is disposed on the inside of the dust cover 13 for being driven by a coil.

[0076] The main body 121 is located on the outside of the dust cover 13. While providing stable structural support for the moving part assembly 12, it can also prevent it from coming into contact with dust or impurities on the surface of the dust cover 13, thereby ensuring that the external structure of the moving part assembly 12 is not contaminated or damaged.

[0077] The mating part 122 is located inside the dust cover 13 and interacts directly with the magnetic field generated by the coil, thereby achieving a highly efficient driving effect.

[0078] Furthermore, in practical use, in order to ensure the driving effect of the magnetic levitation system 1, a coil is also provided inside the mating part 122. Therefore, placing the mating part 122 inside the dust cover 13 can also protect the mating part 122, prevent dust or impurities from falling into the mating part 122, ensure that the magnetic connection between the coils is not disturbed, thereby ensuring the stability of the magnetic field and ensuring the transmission accuracy.

[0079] In some embodiments, refer to Figure 5 As shown, the mover assembly 12 also includes a slider 123, which is disposed on the mating part 122 for movement along the track 111.

[0080] Thus, the slider 123 enables the mover assembly 12 to achieve smoother and more precise motion control during operation, further improving the positioning accuracy and repeatability of the system, and enabling it to better adapt to the high-precision and high-efficiency magnetic levitation transmission requirements.

[0081] In some embodiments, refer to Figure 5 As shown, the mating part 122 is provided with a relief groove 124, and the housing 112 is partially disposed in the relief groove 124. The inner wall of the relief groove 124 is provided with multiple heat dissipation notches.

[0082] Since the magnetic levitation system 1 generates heat during operation, the heat dissipation gap can effectively promote air circulation in the clearance slot 124, accelerate heat dissipation, prevent excessive local temperature from damaging the coil, housing 112 or other components, and extend the service life of the magnetic levitation system 1.

[0083] In some embodiments, refer to Figure 4 As shown, the housing 112 is provided with a limiting groove 114, and the connector 132 is provided with a limiting plate 133 corresponding to the limiting groove 114. The limiting plate 133 is engaged with the limiting groove 114.

[0084] Thus, through the snap-fit ​​between the limiting plate 133 and the limiting groove 114, the dust cover 13 is precisely positioned during installation, effectively preventing the dust cover 13 from shifting or loosening during operation, ensuring that it is always in the best protective position, thereby continuously and effectively blocking dust, ink splatter and other impurities from entering the track 111 area, ensuring the stability of the magnetic field and the transmission accuracy of the system.

[0085] Furthermore, the engagement of the limiting plate 133 with the limiting groove 114 simplifies the installation and disassembly of the dust cover 13, making maintenance operations more convenient and efficient, and further enhancing the maintainability and practicality of the magnetic levitation system 1.

[0086] In some embodiments, refer to Figure 3 As shown, the dust cover 13 also includes a support portion 134, which protrudes from the first surface 1311 of the cover body 131. The connector 132 is connected to the support portion 134 so that a clearance space 135 is formed between the connector 132 and the cover body 131 to avoid at least part of the moving part assembly 12.

[0087] In this way, interference between the dust cover 13 and the moving part 12 can be effectively avoided, allowing the moving part 12 to pass smoothly during operation. This reduces the stability of the interfering magnetic field and ensures transmission accuracy without affecting magnetic levitation transportation, while also ensuring the motion accuracy and stability of the system.

[0088] Meanwhile, the design of the clearance space 135 also provides greater freedom of movement for the moving part 12, reducing the risk of friction or collision caused by space constraints, and further improving the operating efficiency and reliability of the magnetic levitation system 1.

[0089] In some embodiments, refer to Figure 3 As shown, the support part 134 is provided with weight reduction holes 136.

[0090] Thus, by opening the weight reduction hole 136 in the support part 134, the overall weight of the dust cover 13 is effectively reduced, thereby reducing the load on the magnetic levitation system 1. The setting of the weight reduction hole 136 also optimizes the use of materials, reduces manufacturing costs, and makes the structure of the dust cover 13 lighter, making it easier to install and disassemble.

[0091] In addition, the weight reduction hole 136 can also improve the heat dissipation performance of the support part 134 to a certain extent, which helps to dissipate heat during system operation and further enhances the stability and reliability of the magnetic levitation system 1.

[0092] It is understood that in this embodiment, the weight reduction hole 136 extends along the length of the dust cover 13.

[0093] In some embodiments, refer to Figure 3 As shown, the cover 131 includes a first connecting plate 1312 and at least two second connecting plates 1313. The side of the first connecting plate 1312 facing the stator assembly 11 is a first surface 1311. The first connecting plate 1312 has a second connecting plate 1313 protruding from each side along the width direction. The connector 132 and the support portion 134 are both located between the two second connecting plates 1313.

[0094] Thus, the side of the first connecting plate 1312 facing the stator assembly 11 serves as the first surface 1311, used to install the connector 132 and the support 134, ensuring a stable connection between the dust cover 13 and the stator assembly 11. The two second connecting plates 1313 protrude from both sides of the first connecting plate 1312 along the width direction, forming a semi-enclosed structure, which not only enhances the overall rigidity and structural strength of the cover 131, but also effectively prevents external impurities from entering the track 111 area from the side, further improving the dustproof effect.

[0095] Meanwhile, the connector 132 and the support 134 are located between the two second connecting plates 1313, making the structure of the dust cover 13 more compact and the installation more stable. It also facilitates the smooth operation of the moving part assembly 12 inside the dust cover 13 and avoids interference.

[0096] In some embodiments, refer to Figure 3 As shown, the first connecting plate 1312 also includes a second surface 1314 facing away from the first surface 1311, and the second surface 1314 is provided with a weight reduction groove 1315.

[0097] By creating a weight-reducing groove 1315 on the second surface 1314, the overall weight of the cover 131 is effectively reduced, thereby reducing the load on the magnetic levitation system 1 and improving the system's operating efficiency and dynamic response performance.

[0098] Meanwhile, the design of the weight reduction groove 1315 optimizes the use of materials, reduces manufacturing costs, and makes the structure of the dust cover 13 lighter, making it easier to install and disassemble.

[0099] In addition, the weight reduction groove 1315 can also enhance the heat dissipation capacity of the cover 131 to a certain extent, which helps to dissipate heat quickly during system operation and further improve the stability and reliability of the magnetic levitation system 1.
