Description

Technical Field

[0001] The present invention relates to the technical field of magnetic suspension transportation, and in particular to a magnetic suspension transportation system for substrates coated with panels. Background Art

[0002] Across many manufacturing sectors, 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 must be accurately delivered to the appropriate workstation before coating. Because the movers are in motion during the conveying process, passive positioning methods are an ideal choice for positioning panels on the movers due to their lack of external energy supply, simple structure, and high reliability.

[0003] However, existing magnetic levitation conveyors still face numerous challenges when applied to panel transportation. Regarding positioning, due to their passive positioning, existing magnetic levitation conveyors struggle to quickly and accurately position panels. Rapid positioning is crucial given the high pace of panel production. Furthermore, the high speed of magnetic levitation conveyors results in significant acceleration. Panels, as fragile components, are susceptible to damage under high acceleration, increasing production costs and the defective rate.

[0004] Furthermore, during operation, the stator of a magnetic levitation conveyor generates a significant amount of heat, which the existing device's heat dissipation design cannot meet. Overheating of the stator can affect the device's performance and lifespan.

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

[0006] To solve the above problems, the present invention provides the following technical solutions: a magnetic suspension conveying system for substrates for panel coating, comprising:

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

[0008] Two sets of sliding seats correspondingly slidably arranged on the slide rails;

[0009] A buffer assembly is supported and connected by two sets of slides, and the buffer assembly has a buffer end, which can provide buffering in the moving direction of the slide;

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

[0011] The limiting component is arranged at the buffer end of the buffer component and is used for carrying and limiting the substrate.

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

[0013] a first plate body, the bottom of which is fixed to the buffer end of the buffer assembly via a first spring;

[0014] a second plate body, which is spaced apart and disposed above the first plate body and is connected to the first plate body via four fixed shafts distributed in a rectangular shape;

[0015] a first arm body, which is rotatably arranged on the fixed shaft;

[0016] a second arm body, which is hinged to the free end of the first arm body;

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

[0018] Furthermore, preferably, a magnetic element is fixed to one end of the first arm away from the second arm;

[0019] Four magnetic members distributed in a rectangular shape are also fixed on the buffer end of the buffer assembly. When the magnetic member moves downward, it can be magnetically attracted by the magnetic member, thereby causing the first arm to deflect and move away from the substrate.

[0020] Furthermore, preferably, the magnetic member is a single-sided magnetic structure, with the magnetic end thereof facing upward.

[0021] Furthermore, preferably, a through hole is provided on the first arm body for rotationally cooperating with the fixed shaft;

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

[0023] a double-arc bracket detachably connected between the through hole and the fixed shaft;

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

[0025] A second spring is connected to the double arc support.

[0026] Furthermore, as a preference, the limiting plate is rotatably arranged on the supporting plate, and the limiting plate is elastic;

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

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

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

[0030] a buffer seat, which is slidably arranged in the buffer groove along the moving direction of the mover;

[0031] A third spring is connected between the buffer groove and the buffer seat.

[0032] Furthermore, as a preference, a mounting groove is provided in the middle of the base for mounting the stator;

[0033] A connecting groove is provided at the bottom of the base, and two adjacent bases are connected via the connecting groove and a connecting piece embedded in the connecting groove.

[0034] Furthermore, preferably, heat dissipation channels opened on the base are provided on both sides of the mounting groove, and a fluid channel opened on the base is provided on one side of each heat dissipation channel, one of the fluid channels is a liquid inlet channel, and the other fluid channel is a liquid discharge channel.

[0035] Furthermore, preferably, a first wire hole and a second wire hole are respectively formed on two side walls of one heat dissipation channel, and a wire groove corresponding to the second wire hole is further formed on the side wall of the base.

[0036] Compared with the prior art, the present invention provides a substrate magnetic levitation conveying system for panel coating, which has the following beneficial effects:

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

[0038] 2. In the present invention, a liquid-cooled heat dissipation structure with a built-in base is adopted. By providing a mounting groove in the middle of the base to accommodate the stator, heat dissipation channels, liquid inlet channels, and liquid discharge channels are provided on both sides, which improves the heat dissipation efficiency compared to the traditional air-cooling solution. More importantly, the modular base can be rapidly expanded through connecting grooves and connectors, and the heat dissipation channel network can be extended synchronously with the length of the system to ensure uniform distribution of coolant flow when multiple bases are connected in series. This architecture not only ensures the thermal stability of the stator under high-speed magnetic levitation conditions, but also avoids the interference of complex external pipes on the magnetic field, providing reliable protection for the continuous production of panels.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, and this is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0048] Example: Please refer to Figure 1-Figure 7 In an embodiment of the present invention, a magnetic suspension conveying system for substrates for panel coating is provided, comprising:

[0049] The base 1 has a stator 13 installed in the middle and two symmetrically arranged slide rails 2 fixed on the top;

[0050] Two sets of slide seats 3 correspondingly slidably arranged on the slide rails 2;

[0051] A 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 slide 3;

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

[0053] The limiting component is provided at the buffer end of the buffer component 4 and is used for supporting and limiting the substrate 20 .

[0054] During implementation, the substrate 20 to be coated is first placed on the limiting assembly, which supports and limits the substrate 20, ensuring that the position of the substrate 20 is stable during transportation. Then, the stator 13 is energized, generating a magnetic field that interacts with the mover 14. Under the action of the magnetic field force, the mover 14 drives the entire buffer assembly 4 and the slide 3 to begin moving along the slide rail 2. During the transportation process, if there is an external impact or a change in the transportation speed, the buffer end of the buffer assembly 4 will provide a buffering effect in the moving direction of the slide 3. For example, when there is a sudden acceleration or deceleration, the buffer end can absorb part of the impact force, reduce the impact on the substrate 20, and ensure smooth transportation of the substrate 20. As the mover 14 moves, the substrate 20 is transported to the coating station, at which point the panel coating operation can be carried out.

[0055] Specifically, the buffer assembly 4 includes:

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

[0057] a buffer seat 42 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] The buffer seat 42 serves as the buffer end of the buffer assembly 4 .

[0060] Specifically, the limiting component includes:

[0061] A first plate 5, the bottom of which is fixed to the buffer end of the buffer assembly 4 via a first spring 7;

[0062] The second plate 6 is spaced apart and disposed above the first plate 5 and is connected to the first plate 5 via four fixed shafts 15 distributed in a rectangular shape;

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

[0064] a second arm 10, which 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 10 , and a limiting plate 12 is further provided on the outer circumference of the support plate 11 .

[0066] The limiting plate 12 can limit the position of the substrate 20, preventing the substrate 20 from shifting and ensuring the position of the substrate 20 during the conveying and coating process. The movable structure of the first arm 9 and the second arm 10 enables the limiting assembly to adapt to substrates 20 of different shapes and sizes, while ensuring the limiting effect and improving the versatility and flexibility of the limiting assembly.

[0067] It should be noted that the second arm 10 can be hinged to the free end of the first arm 9 by bolts. Generally, the relative positions of the second arm 10 and the first arm 9 remain unchanged. Corresponding adjustments are only made when replacing the base plate 20 of different sizes.

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

[0069] A through hole 17 is formed on the first arm 9 for rotating with the fixed shaft 15, and a plurality of reset components are installed between the through hole 17 and the fixed shaft 15;

[0070] Four rectangularly distributed magnetic members 8 are also fixed to the buffer end of the buffer assembly 4 . When the magnetic 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 .

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

[0072] In addition, the reset component includes:

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

[0074] Two symmetrically arranged slow-rebound ends 18 are respectively fixed to the upper and lower ends of the double-arc bracket 16, so that the double-arc bracket 16 and the slow-rebound end 18 form a whole;

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

[0076] Before unloading or loading, an external robotic arm is used to drive the second plate 6 downward, the first spring 7 is compressed, and the magnetic member 91 also moves downward. When the magnetic member 91 moves to a position where it can be magnetically attracted by the magnetic member 8, the magnetic member 8 generates a magnetic attraction force on the magnetic member 91. This magnetic attraction force overcomes the force of the reset assembly on the first arm 9, causing the first arm 9 to deflect and move away from the substrate 20. In this process, the deflection of the first arm 9 will cause the double-arc bracket 16 to deform. At the same time, the slow rebound ends 18 at the upper and lower ends of the double-arc bracket 16 will be stretched, and the second spring 19 will also elongate, resulting in elastic deformation.

[0077] When the loading or unloading operation is completed, the external robotic arm no longer applies downward force to the second plate 6. The first spring 7 begins to return to its original shape, pushing the second plate 6 upward. The magnetic element 91 also moves upward, and the magnetic attraction force gradually decreases. At this time, the elastic potential energy stored in the second spring 19 begins to be released, which pushes the double-arc bracket 16 back to its initial position, thereby driving 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, ready for the next substrate 20 conveying and limiting.

[0078] It should be noted that the slow rebound characteristic of the slow rebound end 18 enables the first arm 9 to slowly and smoothly return to its initial position during the reset process, avoiding the impact and vibration caused by resetting too quickly, ensuring the stability of the limit assembly, and facilitating the subsequent limiting of the substrate 20. The second spring 19 provides a 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 limit plate 12 is once again in the appropriate limiting position, ensuring the limiting effect for substrates 20 of different sizes.

[0079] Preferably, the magnetic member 8 is a single-sided magnetic structure, with the magnetic end thereof facing upward.

[0080] The single-sided magnetic structure means that the magnetic field of the magnetic element 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. Positioning the magnetic end upward can make the magnetic field mainly toward the magnetic element 91 and away from the area where the stator 13 and mover 14 are located, thereby effectively reducing the interference of the magnetic field on the stator 13 and mover 14.

[0081] Exemplarily, the magnetic member 8 includes a columnar magnet and a magnetic shielding sleeve wrapped around the magnet and allowing the upper end of the magnet to leak out.

[0082] In this embodiment, the limiting plate 12 is rotatably disposed on the supporting plate 11, and the limiting plate 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 conveying process of the substrate 20, slight positional deviation may occur due to various factors (such as equipment vibration, conveying speed changes, etc.). The rotation of the limit plate 12 can better adapt to such slight deviations, allowing the substrate 20 to move relatively smoothly while being limited, reducing the risk of jamming or damage caused by positional deviation.

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

[0086] A connecting groove 102 is formed at the bottom of the base 1 , and two adjacent bases 1 are connected via the connecting groove 102 and a connecting piece embedded in the connecting groove 102 .

[0087] The design of the connection slots 102 and connectors allows for flexible expansion or adjustment of the length and scale of the conveying system based on actual needs. For example, when the conveying distance needs to be increased, a new base 1 can be easily added and connected to the existing base 1 via the connection slots 102 and connectors, thereby improving the scalability and flexibility of the system.

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

[0089] The heat dissipation channels 103 provided on both sides of the mounting slot 101 effectively improve the heat dissipation efficiency of the stator 13. During operation of the magnetic levitation conveying system, the stator 13 generates heat. If this heat cannot be dissipated promptly, the temperature of the stator 13 will rise, affecting its performance and lifespan. The presence of the heat dissipation channels 103 provides a channel for heat dissipation, ensuring that the stator 13 operates at an appropriate temperature.

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

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

[0092] A first cable hole 104 and a second cable hole 106, respectively defined on the sidewalls of one heat dissipation channel 103, provide passageways for routing cables associated with the stator 13. In a magnetic levitation conveying system, the stator 13 requires connections to various cables (such as power cables and signal cables). The cable holes allow these cables to be routed orderly through the heat dissipation channel 103, avoiding disorganization and reducing interference and wear between cables, thereby improving system reliability and safety.

[0093] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
