Background Technology

[0002] Ultra-high flexibility magnetic levitation logistics lines are material transport mechanisms used in semiconductor and chip manufacturing, biomedicine and medical devices, aerospace, large ports and airports, national or regional logistics hubs, large e-commerce warehousing parks, and city-level central warehouse to forward warehouse networks. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of ultra-high flexibility magnetic levitation logistics lines.

[0003] Existing magnetic levitation logistics lines have certain drawbacks in use, including low speed, poor stability, and limited flexibility. The paths are typically fixed straight lines or simple curves, making it difficult to achieve free and intelligent routing and merging / diversion on complex two-dimensional or three-dimensional grid networks. Placement is limited by space constraints, preventing unlimited extension. The path may deviate during operation. Furthermore, it cannot simultaneously achieve high speed and high thrust, limiting its industry applications and negatively impacting practical use. Therefore, we propose an ultra-flexible magnetic levitation logistics line. Utility Model Content

[0024] like Figure 1-7 As shown, an ultra-flexible magnetic levitation logistics line includes a base 1 and a trolley 9. The trolley 9 moves on the base 1. A motor 2 is mounted on the upper center of the base 1. A V-rail 3 is integrally mounted on one side of the upper end of the base 1, and a flat rail 4 is integrally mounted on the other side of the upper end of the base 1. A cover plate 13 and an end plate 14 are positioned on the upper end of the base 1 outside the motor 2. A magnet 11 and an encoder sensing magnet 12 are provided at the bottom of the trolley 9. A V-wheel 5 is provided between the trolley 9 and the V-rail 3, and a flat wheel 6 is provided between the trolley 9 and the flat rail 4. Anti-tipping accessories 10 are installed on the sides of the trolley 9. Lubrication boxes 7 are provided between V-rail 3 and flat rail 4. Connectors 8 are located between the V-wheel 5, flat wheel 6 and the protruding structures on both sides of the base 1. The top of the connector 8 is locked to the trolley 9. The bottom of the trolley 9 is engaged and fixed with the magnet 11. The magnet 11 is combined with the motor 2. Multiple magnets 11 are arranged to form a relative magnetic circuit. After the motor 2 is powered on, a stable magnetic field is formed. The motor 2 moves without contact after being powered on, eliminating the cogging force. The V-wheel 5 and flat wheel 6 at the bottom of the trolley 9 move horizontally on the V-rail 3 and flat rail 4 respectively. The upper end of the base 1 is protected by the cover plate 13 and the end plate 14.

[0025] like Figure 8As shown, an installation component 15 is positioned between the trolley 9 and the lubrication box 7. A drip irrigation hole 16 is provided in the middle of the bottom end of the lubrication box 7. A support member 18 is provided at the lower end of the lubrication box 7. Lubricating cotton 17 is installed in the middle of the support member 18. A positioning plate 21, a spring 20 and a damper 19 are provided between the lubrication box 7 and the support member 18. The spring 20 and the damper 19 are both located inside the positioning plate 21, and the spring 20 is located outside the damper 19. The support member 18 moves elastically at the lower end of the lubrication box 7 through the spring 20 and the damper 19, so that the support member 18 and the lubricating cotton 17 are in close contact with the bottom track. The drip irrigation hole 16 at the bottom of the lubrication box 7 drips lubricating oil into the surface of the lubricating cotton 17. Our self-developed base profile saves raw materials and provides stability. While ensuring key mechanical properties, we precisely remove redundant materials, reducing raw material consumption and overall weight from the source. At the same time, through innovative cross-sectional shape design and one-piece molding process, we significantly improve the bending and torsional rigidity of the profile, ensuring stable vibration-free performance of the equipment under high-speed operation or complex loads. By cleverly utilizing the combination of "V-wheel + flat wheel", the system's durability, environmental adaptability and ease of maintenance are greatly improved while ensuring high precision and strong load-bearing capacity. Unique anti-rollover components are integrated between the rollers on both sides of the trolley and rigidly connected to the vehicle body. This design provides the system with crucial anti-rollover stability, ensuring safety and accuracy; furthermore, its ingenious mechanical structure allows for quick assembly and disassembly, greatly simplifying the maintenance process. The semi-automatic lubrication box is specially designed to tightly enclose the V-rollers and flat rollers, and is adjusted to fit the roller shape. This lubrication box provides a controlled, continuous, and clean supply of lubricating oil to the guide rails, effectively reducing friction and wear, while also providing heat dissipation and corrosion protection. Each trolley is equipped with four rollers, each with an integrated lubrication box at the front. One set of lubrication boxes provides long-lasting lubrication, covering the lubrication needs of tens of meters of guide rails, significantly extending equipment lifespan and reducing maintenance frequency.

[0026] Working Principle: This utility model includes a base 1, a motor 2, a V-rail 3, a flat rail 4, a V-wheel 5, a flat wheel 6, a lubrication box 7, a connecting piece 8, a trolley 9, an anti-tipping accessory 10, a magnet 11, an encoder sensing magnet 12, a cover plate 13, an end plate 14, a mounting assembly 15, a drip irrigation hole 16, lubricating cotton 17, a support piece 18, a damper 19, a spring 20, and a positioning plate 21. The base 1 is made of one-piece molded aluminum material. This base has a stable structure, strong resistance to deformation, and aluminum profile is a good conductor of heat, which helps the motor dissipate heat, ensures stable operation, and extends its service life. The base has a symmetrical design with "hook" and "slot" structures on the left and right sides, which can be perfectly combined with other components and facilitate the locking of encoders and other accessories. The middle is a relatively wide main body, with a row of motors 2 placed on top. The motor and encoder extension cables are connected to an external driver. The external driver eliminates cable drag and utilizes drive control software to improve production cycle time, greatly reducing the constraints of traditional conveyor machinery hardware. The base features integrated V-rails 3 and flat rails 4 on both sides. This integrated design eliminates minor errors, gaps, or inconsistencies at the joints, making the entire guide rail system a rigid whole with better dynamic response characteristics, preventing minor deformations or vibrations during high speeds or acceleration. The V-rail + flat rail design perfectly combines the precise guidance of the V-rail with the robust load-bearing capacity of the flat rail, ultimately achieving a comprehensive improvement in the speed, accuracy, stability, and lifespan of the magnetic levitation system. V-wheels 5 and flat wheels 6 are placed on the V-rails and flat rails respectively. Here, "wheels" refers to rollers with bearings (V-shaped rollers and flat-edged rollers), which roll on their respective tracks (V-rails and flat rails). The core advantage of the "V-wheel + flat wheel" combination lies in its ingenious integration of high-precision guidance, strong load-bearing capacity, ease of installation, and excellent resistance to contamination. The lubrication box 7 encloses the V-wheel and flat wheel, and is adjusted according to the shape of the rollers. This semi-automatic lubrication box supplies lubricating oil to the slide rail in a controlled, continuous, and clean manner to reduce friction, wear, heat dissipation, and corrosion prevention. Each trolley has four rollers, with the front roller enclosing the lubrication box. One lubrication box can lubricate tens of meters of guide rail. A connecting piece 8 is designed between the rollers and the protruding structures on both sides of the base. The connecting piece locks to the trolley 9 above, ensuring that the rollers drive the trolley along the guide rail and improving stability. Anti-tipping accessories 10 are designed between the two rollers on both sides, also locked to the trolley. This accessory has a unique design; it is not only a crucial safety and performance component in the motion system, ensuring safe, accurate, and long-term operation of magnetic levitation transport, but its unique design also allows for quick assembly and disassembly of the trolley, making installation simple. The V-wheel and flat wheel support the trolley, and goods are placed on top of the trolley. The trolleys can be placed freely on the line, with no limit on the number. Magnet 11 is installed directly below the car. The magnet is combined with the motor, and multiple magnets are arranged to form a relative magnetic circuit. After the motor is powered on, a stable magnetic field is formed. The motor moves without contact after being powered on, eliminating cogging force and significantly improving high acceleration performance and dynamic response characteristics.The trolley, along with the encoder sensing magnet 12 mounted below, forms a high-precision position feedback system corresponding to the encoder below. This system converts mechanical displacement (linear or rotational) into electrical signals in real time and with high precision, thereby achieving precise closed-loop control of position and speed. To better protect the internal structure, multiple protective sheet metal panels are designed externally. A cover plate 13 is designed in the middle section, cut into the shape of the motor to avoid affecting the magnetic field, while the rest of the plate fully covers the interior. End plates 14 are also designed at both ends to protect the internal structure.
