Description

Technical Field

[0001] The present application relates to the field of transportation technology, and in particular to a magnetic levitation conveyor line. Background Art

[0002] The magnetic drive transmission line is mainly composed of a mover and a stator. The current passes through the coil of the stator to generate a magnetic field, which interacts with the magnetic field of the permanent magnet plate on the mover to cause movement. The position detection device obtains the position, speed and other motion state data of the mover to the control system, and adjusts the strength and direction of the magnetic field by controlling the current in the coil to maintain the desired position and speed of the mover, thereby achieving precise control of the mover movement.

[0003] Because magnetic drive conveyor lines have the characteristics of flexible design, in the actual production process, according to factors such as space limitations and transportation requirements, different shapes of tracks such as straight, circular, and curved are designed to adapt to different application scenarios to the greatest extent. For areas with specific movement path requirements, curved tracks can be used to flexibly adjust the layout, bypass obstacles, and are not constrained by space, minimizing friction, achieving smoother and faster movement, and improving the efficiency and speed of the maglev conveyor line. Compared with right-angle turns or other forms of turns, curved turns can be completed in a relatively short distance, thereby saving space and improving efficiency.

[0004] In the related art, when using a curved line for transportation, for the same type of stator, when a single mover is used for transportation, its load-bearing capacity is limited. If the load capacity on the curved line is to be increased, a mover module with a larger load capacity needs to be designed. In order to control costs, a double mover transportation solution is adopted. However, although the double mover transportation can increase the load, it cannot pass through the arc section of the magnetic drive conveyor line. Summary of the invention

[0009] Wherein, the supporting plates on the two adjacent movers are used to jointly support materials.

[0010] In one embodiment, a mounting groove is formed on the fixed portion, and the rotating mechanism further includes a bearing, the bearing is installed in the mounting groove, and the bearing sleeve is arranged outside the rotating portion.

[0035] Logistics conveyor lines are widely used in various fields such as express sorting, warehousing and transportation, and manufacturing. Traditional logistics conveyor lines mostly use belt transmission. The principle of belt transmission is to use friction to transport workpieces, so it cannot stop suddenly, which limits its conveying speed and directly affects the overall efficiency of the conveyor line. Among the related technologies, the conveying of workpieces through magnetic drive technology has the characteristics of fast conveying speed, low maintenance cost, and high flexibility, and has been increasingly favored.

[0036] The magnetic drive transmission line is mainly composed of a mover and a stator. The current passes through the coil of the stator to generate a magnetic field, which interacts with the magnetic field of the permanent magnet plate on the mover to cause movement. The position detection device obtains the position, speed and other motion state data of the mover to the control system, and adjusts the strength and direction of the magnetic field by controlling the current in the coil to maintain the desired position and speed of the mover, thereby achieving precise control of the mover movement.

[0037] Because magnetic drive conveyor lines have the characteristics of flexible design, in the actual production process, according to factors such as space limitations and transportation requirements, different shapes of tracks such as straight, circular, and curved are designed to adapt to different application scenarios to the greatest extent. For areas with specific movement path requirements, curved tracks can be used to flexibly adjust the layout, bypass obstacles, and are not constrained by space, minimizing friction, achieving smoother and faster movement, and improving the efficiency and speed of the maglev conveyor line. Compared with right-angle turns or other forms of turns, curved turns can be completed in a relatively short distance, thereby saving space and improving efficiency.

[0038] The application of magnetic drive conveyor lines is not limited to the field of material transportation. Due to its advantages such as flexible design, high-precision control and high stability, it can also be widely used in precision machinery manufacturing, electronic information, biomedicine and other fields. For example, in the biomedical field, magnetic drive conveyor lines can be used to achieve micron-level precision drug transportation and cell transplantation operations, improving the accuracy and safety of medical processes.

[0039] In the related art, when using a curved line for transportation, for the same type of stator, when a single mover is used for transportation, its load-bearing capacity is limited. If the load capacity on the curved line is to be increased, a mover module with a larger load capacity needs to be designed. In order to control costs, a double mover transportation solution is adopted. However, although the double mover transportation can increase the load, it cannot pass through the arc section of the magnetic drive conveyor line.

[0040] In view of the above problems, referring to FIG. 1 , FIG. 2 and FIG. 3 , the embodiment of the present application provides a magnetic levitation conveyor line 10, comprising a conveying rail 100 and at least two movers, the two movers being movably arranged on the conveying rail 100 along the extending direction of the conveying rail 100. Each mover comprises a mover body 200, a rotating mechanism 400 and a supporting plate 300. The supporting plate 300 is used to support the material 500, and the two rotating mechanisms 400 are arranged between the mover assembly and the supporting plate 300.

[0041] Referring to Figures 1, 2 and 3, the conveying rail 100 includes a straight segment 110 and an arc segment 120. Specifically, the conveying rail 100 may include a plurality of straight segments 110 and a plurality of arc segments 120. The straight segment 110 is used to convey the support plate 300 in a straight direction, and the arc segment 120 is used to convey the support plate 300 in a turning direction. It should be noted that in the present application, the curvature of the arc segment 120 is not limited and can be set according to actual use requirements.

The rotating mechanism 400 includes a fixed portion 410 and a rotating portion 420, and the rotating portion 420 is rotatably connected to the fixed portion 410. The fixed portion 410 is connected to the mover body 200. The rotating portion 420 is connected to the support plate 300, wherein the support plates 300 on the two adjacent mover bodies 200 are used to jointly support the material 500. That is, in this application, it is a double mover transportation. During transportation, the two adjacent movers have the same moving speed and moving direction.

[0044] By rotatably connecting the rotating part 420 to the fixed part 410, when the fixed part 410 moves with the mover body 200, the fixed part 410 will not rotate, while the rotating part 420 can rotate freely, and the supporting plates 300 on the two adjacent movers are used to jointly support the material 500. When the mover passes through the arc segment 120, the two rotating parts 420 can be rotated to adjust the posture of the material 500 to achieve turning.
