Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a novel magnetic levitation conveying device. Background Technology

[0002] In industrial production, conveying devices are key equipment for material transfer. Traditional conveying systems mostly rely on mechanical contact methods, such as rollers, chains, or belts. Although these methods are simple and easy to use, they have inherent defects, including high friction loss, frequent component wear, significant noise pollution, and low energy efficiency, resulting in high maintenance costs and operational interruptions.

[0003] With the introduction of magnetic levitation technology, the aim is to eliminate physical contact, reduce friction and wear, and improve conveying speed and accuracy. However, existing magnetic levitation conveying devices still face many challenges. For example, in terms of magnetic pole arrangement, existing technologies often use fixed magnetic pole structures, which may lead to uneven magnetic field distribution, affecting the stability of levitation force and the smoothness of conveying, thus causing a decrease in positioning accuracy and vibration problems. In addition, the installation and adjustment of slide rails usually rely on bolts or simple clamping methods, which are prone to loosening due to vibration or load changes, requiring frequent realignment, increasing installation complexity and maintenance burden, and may also lead to sluggish operation or additional friction. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is: how to provide a new type of magnetic levitation conveying device to improve the conveying stability and smoothness of the magnetic levitation conveying device.

[0005] To achieve the above objectives, this utility model proposes a novel magnetic levitation conveying device, which includes a support, a base, a slide rail, a slide rail mounting block, a stator motor, and multiple sliding components. The sliding components include a mounting block, a support plate, a magnetic pole fixing block, a first magnetic pole, and a second magnetic pole.

[0006] The base is fixedly mounted on the bracket, the slide rail is fixedly mounted on the base, the two slide rails are arranged in parallel on both sides of the base, and a receiving groove is provided on the base between the two slide rails, and the stator motor is fixedly mounted in the receiving groove.

[0007] The base is provided with a mounting groove, and the slide rail mounting block is provided in the mounting groove. In the width direction of the base, the slide rail mounting block is positioned closer to the stator motor than the slide rail. The side of the slide rail mounting block facing the stator motor is inclined. The surface of the slide rail mounting block facing the stator motor in the mounting groove is also inclined. During the downward movement of the slide rail mounting block, the inclined surface drives the surface of the slide rail mounting block away from the stator motor to press against the side of the slide rail.

[0008] The mounting block is fixedly disposed at the bottom of the support plate and is slidably connected to the slide rail. The magnetic pole fixing blocks are disposed at the bottom of the support plate and are respectively located on both sides of the stator motor. The magnetic pole fixing blocks located on both sides of the stator motor are respectively provided with the first magnetic pole and the second magnetic pole.

[0009] Furthermore, the first magnetic pole and the second magnetic pole have opposite polarities, the stator motor is located between the first magnetic pole and the second magnetic pole, and the first magnetic pole, the second magnetic pole and the magnetic pole fixing block are all located in the receiving groove.

[0010] Furthermore, a gap is formed between the top of the magnetic pole fixing block and the bottom surface of the support plate, and a wedge-shaped notch is provided at the bottom of the magnetic pole fixing block.

[0011] Furthermore, anti-collision rubber blocks are provided at the ends of the support plate, and the anti-collision rubber blocks are respectively provided at both ends along the length direction of the support plate.

[0012] Furthermore, a sheet metal cover plate is provided below the base, and heat dissipation holes are provided on the sheet metal cover plate.

[0013] Furthermore, multiple slide rail mounting blocks are spaced apart along the length of the slide rail.

[0014] Furthermore, in the height direction of the magnetic pole fixing block, the width of the lower part of the magnetic pole fixing block gradually decreases from top to bottom.

[0015] Compared with related technologies, the novel magnetic levitation conveying device proposed in this utility model has the following advantages:

[0016] The inclined design of the slide rail mounting block drives it to press against the side of the slide rail when it moves downward, realizing self-adjustment and fastening functions, ensuring the stability and alignment accuracy of the slide rail, and avoiding the loosening or offset problems that may occur in traditional installation methods.

[0017] The magnetic pole fixing block is set at the bottom of the support plate and is equipped with a first magnetic pole and a second magnetic pole with opposite polarities. It works with the stator motor to generate a uniform and controllable magnetic levitation force, which enables the sliding component to float smoothly and reduce energy loss and noise.

[0018] The anti-collision rubber blocks at the ends of the support plate provide effective impact protection, preventing damage to the equipment due to collisions during operation and enhancing safety and reliability. The sheet metal cover plate under the base is equipped with ventilation holes to promote heat dissipation, preventing overheating of the motor and magnetic pole components, and ensuring the stability and lifespan of the device during long-term operation.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figure 1 - Figure 4 As shown, this utility model proposes a novel magnetic levitation conveying device, which includes a support 11, a base 12, a slide rail 13, a slide rail mounting block 14, a stator motor 15, and multiple sliding components. The sliding components include a mounting block 21, a support plate 22, a magnetic pole fixing block 23, a first magnetic pole 31, and a second magnetic pole 32.

[0025] The base 12 is fixedly mounted on the bracket 11, and the slide rail 13 is fixedly mounted on the base 12. The two slide rails 13 are arranged in parallel on both sides of the base 12. A receiving groove is provided on the base 12 between the two slide rails 13, and the stator motor 15 is fixedly mounted in the receiving groove.

[0026] The base 12 is fixedly mounted on the bracket 11, thereby establishing a support frame for the entire device, ensuring its stability and rigidity during operation, and preventing positional displacement caused by external vibration or load changes.

[0027] The slide rails 13 are fixedly mounted on the base 12, and the two slide rails 13 are arranged in parallel on both sides of the base 12. They guide the sliding components to move smoothly along a predetermined path, reducing friction and jamming, thereby improving conveying accuracy and efficiency. The parallel arrangement of the slide rails 13 ensures the straightness of the sliding direction, making it suitable for high-precision industrial applications, such as automated production lines.

[0028] A receiving slot is provided on the base 12 between the two slide rails 13, and the stator motor 15 is fixedly installed inside it, concentrating and protecting the stator motor 15 from external impacts or contamination. The integrated layout of the receiving slot optimizes space utilization, allowing the stator motor 15 to directly interact with the magnetic poles of the sliding component, achieving efficient magnetic levitation and driving function, thereby reducing energy loss and enhancing system responsiveness.

[0029] A mounting groove is provided on the base 12, and a slide rail mounting block 14 is provided in the mounting groove. In the width direction of the base 12, the slide rail mounting block 14 is positioned closer to the stator motor 15 than the slide rail 13.

[0030] The side of the slide rail mounting block 14 facing the stator motor 15 is inclined. The surface of the mounting groove that fits with the side of the slide rail mounting block 14 facing the stator motor 15 is also inclined. During the downward movement of the slide rail mounting block 14, the inclined surface drives the surface of the slide rail mounting block 14 away from the stator motor 15 to press against the side of the slide rail 13. Multiple slide rail mounting blocks 14 are spaced apart along the length of the slide rail 13.

[0031] The side of the slide rail mounting block 14 facing the stator motor 15 is inclined, and the mating surface inside the mounting groove is also inclined. This allows the surface of the slide rail mounting block 14 away from the stator motor 15 to actively press against the side of the slide rail 13 during downward movement of the slide rail mounting block 14 through the wedge-shaped action of the inclined surface. The slide rail mounting block 14 not only secures the slide rail 13, preventing displacement under vibration or load changes, but also allows for some thermal expansion compensation, ensuring the adaptability and durability of the device in temperature fluctuation environments and reducing maintenance requirements.

[0032] Multiple slide rail mounting blocks 14 are spaced apart along the length of the slide rail 13, which provides uniform support and fixing points, effectively dispersing mechanical stress and load, avoiding local deformation or bending of the slide rail 13, and thus ensuring smooth movement of the sliding assembly.

[0033] A sheet metal cover 27 is provided below the base 12, and heat dissipation holes are provided on the sheet metal cover 27. The sheet metal cover 27 below the base 12 is equipped with heat dissipation holes, which promotes heat dissipation, prevents the motor and magnetic pole assembly from overheating, and ensures the stability and lifespan of the device during long-term operation.

[0034] Mounting block 21 is fixedly installed at the bottom of support plate 22. Mounting block 21 is slidably connected to slide rail 13. Magnetic pole fixing block 23 is installed at the bottom of support plate 22 and located on both sides of stator motor 15. Magnetic pole fixing block 23 located on both sides of stator motor 15 is respectively provided with first magnetic pole 31 and second magnetic pole 32.

[0035] The first magnetic pole 31 and the second magnetic pole 32 have opposite polarities. The stator motor 15 is located between the first magnetic pole 31 and the second magnetic pole 32. The first magnetic pole 31, the second magnetic pole 32 and the magnetic pole fixing block 23 are all located in the receiving groove.

[0036] The mounting block 21 is fixedly installed at the bottom of the support plate 22 and slidably connected to the slide rail 13. Its purpose is to achieve stable support and precise guidance for the support plate 22, and ensure that the sliding component can move smoothly along the slide rail 13, thereby improving the linear motion accuracy and efficiency of the conveying device.

[0037] Magnetic pole fixing blocks 23 are disposed at the bottom of the support plate 22 and located on both sides of the stator motor 15. Each magnetic pole fixing block 23 is provided with a first magnetic pole 31 and a second magnetic pole 32, with the first magnetic pole 31 and the second magnetic pole 32 having opposite polarities. This arrangement generates a symmetrical magnetic field distribution, enabling the stator motor 15 to efficiently drive the support plate 22 to move using magnetic levitation force.

[0038] A gap 24 is formed between the top of the magnetic pole fixing block 23 and the bottom surface of the support plate 22. A wedge-shaped notch 25 is provided at the bottom of the magnetic pole fixing block 23. In the height direction of the magnetic pole fixing block 23, the width dimension of the lower part of the magnetic pole fixing block 23 gradually decreases from top to bottom.

[0039] A gap 24 is formed between the top of the magnetic pole fixing block 23 and the bottom surface of the support plate 22. This design is intended to provide space for airflow, so as to facilitate natural convection during the movement of the sliding component, thereby effectively dissipating the heat accumulated in the areas of the magnetic pole fixing block 23 and the support plate 22.

[0040] The setting of gap 24 creates a channel for airflow, allowing cooling air to be drawn in from the surrounding environment and flow along the contact surface, carrying away the heat generated by the operation and friction of the magnetic poles, reducing thermal resistance, and preventing excessive temperature from affecting magnetic properties or mechanical stability.

[0041] The bottom of the magnetic pole fixing block 23 is provided with a wedge-shaped notch 25, and the width of the lower part of the magnetic pole fixing block 23 gradually decreases from top to bottom. This wedge-shaped structure guides the airflow to form a directional flow channel during movement, enhancing the efficiency of air intake and exhaust. The wedge-shaped notch 25 can accelerate the airflow speed, improve heat dissipation capacity, and reduce airflow resistance, ensuring a continuous cooling effect during high-speed delivery. This airflow channel works in conjunction with the top gap 24 to form a complete heat dissipation path.

[0042] Anti-collision rubber blocks 26 are provided at the ends of the support plate 22, and the anti-collision rubber blocks 26 are respectively located at both ends of the support plate 22 along its length. The purpose of providing anti-collision rubber blocks 26 at the ends of the support plate 22 and at both ends of the support plate 22 along its length is to provide an effective buffer and protection mechanism to prevent the support plate 22 from having a hard collision with the external structure during high-speed movement or at the end position.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
