Description

Technical Field

[0001] This invention relates to the field of magnetic levitation transport technology, and more specifically to a magnetic levitation transport system for a panel-coated substrate. Background Technology

[0002] In the many sub-sectors of manufacturing, the efficient and precise transport of panels using magnetic levitation conveyors is undoubtedly a crucial step in the production process. In the panel coating industry, panels need to be accurately delivered to the corresponding workstations before coating. Since the mover is in a moving state during the transport process, passive positioning methods are the most ideal choice when positioning panels on the mover due to their advantages of requiring no external power supply, simple structure, and high reliability.

[0003] However, existing magnetic levitation conveyor systems still face numerous challenges when applied to panel transport. From a positioning perspective, based on passive positioning, existing magnetic levitation conveyor systems struggle to achieve rapid and accurate panel positioning. Rapid positioning capability is crucial in the high-efficiency pace of panel production. Simultaneously, the high speed of magnetic levitation conveyors results in significant acceleration. Panels, being relatively fragile components, are easily damaged under such high acceleration, increasing production costs and defect rates.

[0004] Furthermore, the stator of the magnetic levitation conveyor generates a large amount of heat during operation, and the existing heat dissipation design is insufficient to meet its cooling requirements. Overheating of the stator will affect the performance and lifespan of the device.

[0005] Therefore, it is necessary to provide a magnetic levitation transport system for panel coating substrates to solve the above problems. Summary of the Invention

[0006] To address the above problems, the present invention provides the following technical solution: a magnetic levitation transport system for a panel coating substrate, comprising:

[0007] The base has a stator installed in the middle and two symmetrically arranged slide rails fixed at the top.

[0008] Two sets of corresponding sliding blocks are slidably disposed on the slide rail;

[0009] A buffer assembly is supported and connected by two sets of slides, and the buffer assembly has a buffer end that can provide buffering in the direction of movement of the slides.

[0010] The mover is fixed below the buffer assembly and maintains an air gap with the stator;

[0011] A limiting component is disposed at the buffer end of the buffer component and is used to support and limit the substrate.

[0012] Furthermore, preferably, the limiting component includes:

[0013] The bottom of the first plate is fixed to the buffer end of the buffer assembly by a first spring;

[0014] The second plate is spaced above the first plate and connected to the first plate by four fixed shafts arranged in a rectangular pattern.

[0015] The first arm is rotatably mounted on the fixed shaft;

[0016] The second arm is hinged to the free end of the first arm;

[0017] A support plate is fixed to the free end of the second arm body, and a limit plate is also provided on the outer circumference of the support plate.

[0018] Furthermore, as a preferred embodiment, a magnetic suction element is fixed to the end of the first arm that is away from the second arm;

[0019] The buffer assembly also has four rectangularly distributed magnetic components fixed on its buffer end. When the magnetic components move downward, they can be attracted by the magnetic components, thereby causing the first arm to deflect and move away from the substrate.

[0020] Furthermore, as a preferred embodiment, the magnetic component is a single-sided magnetic structure, with the magnetic end facing upwards.

[0021] Furthermore, as a preferred embodiment, the first arm body is provided with a through hole for rotatably engaging with the fixed shaft;

[0022] A plurality of reset components are installed between the through hole and the fixed shaft, the reset components including:

[0023] A double-arc bracket, which is detachably connected between the through hole and the fixed shaft;

[0024] Two symmetrically arranged slow rebound ends are fixed to the upper and lower ends of the double arc bracket, respectively, so that the double arc bracket and the slow rebound ends form a whole.

[0025] The second spring is connected to the double-arc bracket.

[0026] Furthermore, preferably, the limiting disk is rotatably mounted on the support disk, and the limiting disk is elastic;

[0027] The upper surface of the support plate is flush with the upper surface of the second plate.

[0028] Furthermore, preferably, the buffer component includes:

[0029] A buffer groove, which is fixed between two sets of slides;

[0030] A buffer seat is slidably disposed in the buffer groove along the moving direction of the mover;

[0031] A third spring connecting the buffer groove and the buffer seat.

[0032] Furthermore, preferably, the base has a mounting groove in the middle for mounting the stator;

[0033] The bottom of the base is provided with a connecting groove, and two adjacent bases are connected by the connecting groove and a connector embedded in the connecting groove.

[0034] Furthermore, as a preferred embodiment, heat dissipation channels are provided on both sides of the mounting groove and on the base, and a fluid channel is provided on one side of each heat dissipation channel and on the base, one of the fluid channels being a liquid inlet channel and the other being a liquid outlet channel.

[0035] Furthermore, as a preferred embodiment, a first wire hole and a second wire hole are respectively provided on the two side walls of one of the heat dissipation channels, and a wire groove corresponding to the second wire hole is also provided on the side wall of the base.

[0036] Compared with the prior art, the present invention provides a magnetic levitation transport system for substrate coating, which has the following advantages:

[0037] 1. In this invention, the problem of substrate damage caused by excessive acceleration in magnetic levitation conveying is effectively solved through the coordinated design of the buffer component and the limiting component. The buffer component adopts a combination structure of a sliding buffer seat and a third spring. When the mover accelerates or decelerates, the buffer seat can generate elastic displacement along the moving direction to absorb impact energy and reduce the inertial force on the substrate. At the same time, the limiting component, through the adjustable first and second arm structures, combined with a magnetic deflection mechanism, achieves adaptive limiting of substrates of different sizes. During the loading / unloading stage, when the robotic arm drives the second plate to press down, the magnetic force of the magnetic components can drive the limiting arm to deflect, avoiding interference. The slow rebound characteristic of the reset component ensures that the limiting plate is smoothly reset, significantly improving the response speed and reliability of passive positioning.

[0038] 2. This invention employs a base-embedded liquid cooling structure. By providing a mounting slot in the center of the base to accommodate the stator, and with cooling channels, liquid inlet channels, and liquid outlet channels on both sides, the heat dissipation efficiency is improved compared to traditional air-cooling solutions. More importantly, the modular base allows for rapid expansion via connecting slots and connectors, and the cooling channel network can extend synchronously with the system length, ensuring uniform coolant flow distribution when multiple bases are connected in series. This architecture guarantees the thermal stability of the stator under high-speed magnetic levitation conditions and avoids interference with the magnetic field caused by complex external piping, providing a reliable guarantee for continuous panel production.

[0047] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0048] Example: Please refer to Figures 1-7 In this embodiment of the invention, a magnetic levitation transport system for a panel-coated substrate is provided, comprising:

[0049] The base 1 has a stator 13 installed in its middle and two symmetrically arranged slide rails 2 fixed at its top.

[0050] Two sets of sliding blocks 3 are correspondingly slidably disposed on the slide rail 2;

[0051] The buffer assembly 4 is supported and connected by two sets of slides 3, and the buffer assembly 4 has a buffer end that can provide buffering in the moving direction of the slides 3.

[0052] The mover 14 is fixed below the buffer assembly 4 and maintains an air gap with the stator 13;

[0053] A limiting component is disposed at the buffer end of the buffer component 4 to support and limit the substrate 20.

[0054] In practice, the substrate 20 to be coated is first placed on the limiting assembly, which supports and limits the substrate 20 to ensure its stable position during transport. Then, the stator 13 is energized, generating a magnetic field that interacts with the mover 14. Under the influence of the magnetic field, the mover 14 drives the entire buffer assembly 4 and the slide block 3 to move along the slide rail 2. During transport, if external impacts or changes in transport speed occur, the buffer end of the buffer assembly 4 provides a buffering effect in the direction of movement of the slide block 3. For example, during sudden acceleration or deceleration, the buffer end can absorb some of the impact force, reducing the impact on the substrate 20 and ensuring smooth transport. As the mover 14 moves, the substrate 20 is transported to the coating station, where the panel coating operation can begin.

[0055] Specifically, the buffer component 4 includes:

[0056] The buffer groove 41 is fixed between the two sets of slides 3;

[0057] The buffer seat 42 is slidably disposed in the buffer groove 41 along the moving direction of the mover 14;

[0058] A third spring 43 is connected between the buffer groove 41 and the buffer seat 42.

[0059] Among them, the buffer seat 42 serves as the buffer end of the buffer assembly 4.

[0060] Specifically, the limiting component includes:

[0061] The bottom of the first plate 5 is fixed to the buffer end of the buffer assembly 4 by the first spring 7;

[0062] The second plate 6 is spaced above the first plate 5 and is connected to the first plate 5 by four fixed shafts 15 arranged in a rectangular pattern.

[0063] The first arm 9 is rotatably mounted on the fixed shaft 15;

[0064] The second arm 10 is hinged to the free end of the first arm 9;

[0065] A support plate 11 is fixed to the free end of the second arm body 10, and a limit plate 12 is also provided on the outer circumference of the support plate 11.

[0066] The limiting disk 12 can limit the substrate 20 to prevent it from shifting and ensure its position during transport and coating. The movable structure of the first arm 9 and the second arm 10 allows the limiting assembly to adapt to substrates 20 of different shapes and sizes, improving the versatility and flexibility of the limiting assembly while ensuring the limiting effect.

[0067] It should be noted that the second arm 10 can be hinged to the free end of the first arm 9 by bolts. Under normal circumstances, the relative position of the second arm 10 and the first arm 9 remains unchanged. Only when the substrate 20 of a different size is replaced, the corresponding adjustment is made.

[0068] Furthermore, a magnetic suction element 91 is fixed to the end of the first arm body 9 away from the second arm body 10;

[0069] The first arm body 9 has a through hole 17 for rotating with the fixed shaft 15, and multiple reset components are installed between the through hole 17 and the fixed shaft 15.

[0070] The buffer assembly 4 is also fixed with four rectangularly distributed magnetic elements 8. When the magnetic element 91 moves downward, it can be attracted by the magnetic elements 8, thereby causing the first arm body 9 to deflect and move away from the substrate 20.

[0071] When a substrate 20 of a different size is replaced, the second arm 10 is adjusted accordingly so that the limiting disk 12 can just limit the substrate 20 in the initial state. In addition, before unloading or loading, the second plate 6 is driven to move downward by an external robotic arm. At this time, the first spring 7 is compressed, and at the same time, the magnetic suction member 91 moves downward. When the magnetic suction member 91 moves downward, it can be magnetically attracted by the magnetic member 8, thereby causing the first arm 9 to deflect and move away from the substrate 20 for unloading or loading.

[0072] Additionally, the reset component includes:

[0073] A double-arc bracket 16 is detachably connected between the through hole 17 and the fixed shaft 15;

[0074] Two symmetrically arranged slow rebound ends 18 are fixed to the upper and lower ends of the double arc bracket 16, thereby making the double arc bracket 16 and the slow rebound ends 18 form a whole.

[0075] The second spring 19 is connected to the double arc bracket 16.

[0076] Before unloading or loading, the second plate 6 is driven downward by an external robotic arm, compressing the first spring 7 and causing the magnetic chuck 91 to move downward as well. When the magnetic chuck 91 moves to a position where it can be attracted by the magnetic component 8, the magnetic component 8 generates a magnetic attraction force on the magnetic chuck 91. This magnetic attraction force overcomes the force exerted by the reset assembly on the first arm 9, causing the first arm 9 to deflect and move away from the substrate 20. During this process, the deflection of the first arm 9 causes the double-arc bracket 16 to deform, and the slow-rebound ends 18 at the upper and lower ends of the double-arc bracket 16 are stretched, causing the second spring 19 to elongate and undergo elastic deformation.

[0077] After the loading or unloading operation is completed, the external robotic arm no longer applies a downward force to the second plate 6. The first spring 7 begins to return to its original state, pushing the second plate 6 upward. The magnetic suction component 91 also moves upward, and the magnetic force gradually decreases. At this time, the elastic potential energy stored in the second spring 19 begins to be released. It pushes the double-arc bracket 16 back to its initial position, thereby causing the first arm 9 to deflect back to its initial position. The slow-rebound end 18 also gradually returns to its original shape, restoring the entire reset assembly to its initial equilibrium state, preparing for the next transport and positioning of the substrate 20.

[0078] It is important to note that the slow-rebound characteristic of the slow-rebound end 18 allows the first arm 9 to return to its initial position slowly and smoothly during the reset process, avoiding impacts and vibrations caused by excessively rapid reset, ensuring the stability of the limiting component, and facilitating the subsequent limiting of the substrate 20. The second spring 19 provides reliable elastic force for the reset of the first arm 9, ensuring that the first arm 9 can accurately return to its initial position, so that the limiting disk 12 is once again in the appropriate limiting position, ensuring the limiting effect on substrates 20 of different sizes.

[0079] Preferably, the magnetic element 8 is a single-sided magnetic structure, with the magnetic end facing upwards.

[0080] A single-sided magnetic structure means that the magnetic field of the magnetic component 8 is mainly concentrated on one side (the magnetic end), while the magnetic field on the other side is very weak or almost non-existent. By setting the magnetic end upwards, the magnetic field direction is mainly directed towards the magnetic attractor 91, away from the area where the stator 13 and the mover 14 are located, thereby effectively reducing the interference of the magnetic field on the stator 13 and the mover 14.

[0081] For example, the magnetic element 8 includes a columnar magnet and a magnetic shielding sleeve that wraps around the magnet and exposes the upper end of the magnet.

[0082] In this embodiment, the limiting disk 12 is rotatably mounted on the support disk 11, and the limiting disk 12 is elastic;

[0083] The upper surface of the support plate 11 is flush with the upper surface of the second plate 6.

[0084] During the transport of substrate 20, slight positional shifts may occur due to various factors (such as equipment vibration, changes in transport speed, etc.). The rotation of the limiting disk 12 can better adapt to these slight shifts, allowing substrate 20 to move relatively smoothly while being limited, reducing the risk of jamming or damage caused by positional shifts.

[0085] In this embodiment, the base 1 has a mounting groove 101 in the middle for mounting the stator 13;

[0086] The bottom of the base 1 is provided with a connecting groove 102, and two adjacent bases 1 are connected by the connecting groove 102 and a connector embedded in the connecting groove 102.

[0087] The design of the connecting groove 102 and the connector allows for flexible expansion or adjustment of the length and scale of the conveying system according to actual needs. For example, when it is necessary to increase the conveying distance, a new base 1 can be easily added and connected to the original base 1 through the connecting groove 102 and the connector, thereby improving the system's expandability and flexibility.

[0088] In this embodiment, heat dissipation channels 103 are provided on both sides of the mounting groove 101 and are opened on the base 1. Each heat dissipation channel 103 has a fluid channel opened on one side of the base 1, one of which is a liquid inlet channel 107 and the other is a liquid outlet channel 108.

[0089] The heat dissipation channels 103 provided on both sides of the mounting slot 101 can effectively improve the heat dissipation efficiency of the stator 13. During the operation of the magnetic levitation conveyor system, the stator 13 will generate heat. If the heat cannot be dissipated in time, the temperature of the stator 13 will rise, affecting its performance and lifespan. The existence of the heat dissipation channels 103 provides a channel for heat dissipation, ensuring that the stator 13 operates at a suitable temperature.

[0090] Furthermore, the fluid channels (inlet channel 107 and outlet channel 108) provided on one side of the heat dissipation channel 103 can further enhance the heat dissipation effect. In implementation, one end of the inlet channel 107 is supplied with liquid by an external liquid supply device, and one end of the outlet channel 108 is connected to an external collection device. In addition, when expanding or adjusting the length and scale of the conveying system, multiple inlet channels 107 form a complete inlet flow channel, and multiple outlet channels 108 form a complete outlet flow channel. When one end of the two is connected in series, a highly efficient liquid cooling heat dissipation system can be formed, which greatly improves the heat dissipation efficiency.

[0091] In this embodiment, a first wire hole 104 and a second wire hole 106 are respectively provided on the two side walls of one of the heat dissipation channels 103, and a wire groove 105 corresponding to the second wire hole 106 is also provided on the side wall of the base 1.

[0092] One of the heat dissipation channels 103 has a first wire hole 104 and a second wire hole 106 respectively opened on the two side walls, providing a channel for the arrangement of cables related to the stator 13. In the magnetic levitation transport system, the stator 13 needs to be connected to various cables (such as power lines, signal lines, etc.). The design of the wire holes allows these cables to pass through the heat dissipation channel 103 in an orderly manner, avoiding the mess of cables, reducing interference and wear between cables, and improving the reliability and safety of the system.

[0093] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
