[0031] Please refer to FIG. 1 and FIG. 2 , an embodiment of the present application relates to a magnetic levitation transportation system 10 , including two magnetic levitation mechanisms and a connecting mechanism 200 , wherein the connecting mechanism 200 is disposed between the two magnetic levitation mechanisms.

[0032] Both magnetic levitation mechanisms include a conveying rail and a mover 100 movably arranged on the conveying rail, and the extension directions of the two conveying rails are parallel to each other. It should be noted that the magnetic levitation mechanism is based on the principle of a linear motor, with the driving coil as the stator and the permanent magnet driving the carrier plate as the mover 100, which can realize the motion control of a single mover 100, greatly improving the flexibility, conveying speed and stability of the conveying system. This application does not limit the structure of the conveying rail, and the conveying rail can be linear or annular. The mover 100 is movably connected to the conveying rail through a slider or roller guide.

[0033] Specifically, the mover 100 is movably arranged on the conveying rail along the extension direction of the conveying rail. More specifically, the mover 100 is guided to move on the conveying rail. The drive coil is configured to generate thrust or pull on the permanent magnet, thereby driving the mover 100 to move along the extension direction of the conveying rail. The drive coil is electrically connected to the power supply. The power supply can provide current to the drive coil, and the force on the permanent magnet can be controlled to be thrust or pull according to the positive and negative current provided by the power supply.

[0034] The connection mechanism 200 is rotatably connected between two correspondingly arranged movers 100, the rotation axis of the connection mechanism 200 is perpendicular to the extension direction of the conveying guide rail and the mover 100, and the connection mechanism 200 is movably connected to at least one mover 100. In other words, one end of the connection mechanism 200 is rotatably connected to the mover 100 of one magnetic suspension mechanism, and the other end of the connection mechanism 200 is rotatably connected to the mover 100 of another magnetic suspension mechanism.

[0035] The connecting mechanism 200 is used to support materials. When the mover 100 moves, it can drive the connecting mechanism 200 to move together, thereby realizing the transportation of materials. It should be noted that: a plurality of movers are arranged on the conveying guide rail. The connecting mechanism 200 can be rotatably connected between two correspondingly arranged movers 100, and the two movers 100 move in one direction at the same time.

[0036] By rotatably connecting the connecting mechanism 200 between the two movers 100, the connecting mechanism 200 is movably connected to at least one mover 100, so that the connecting mechanism 200 can have a rotation amount during the movement process, and at the same time, the connecting mechanism 200 can generate a displacement amount when rotating, thereby effectively avoiding the connecting mechanism 200 from getting stuck, and further ensuring the stability of material transportation while ensuring the transportation speed.

[0037] Referring to Figures 1 and 2, according to some embodiments of the present application, optionally, the connection mechanism 200 and the two movers 100 can be detachably connected.

The moving direction of the connection mechanism 200 relative to the mover 100 is parallel to the moving direction of the mover 100.

[0039] By movably connecting one end of the connecting mechanism 200 to one of the two movers 100, the connecting mechanism 200 can generate displacement when rotating to prevent the connecting mechanism 200 from getting stuck. The other end of the connecting mechanism 200 is fixedly connected to the other mover 100 of the two movers 100 to fix the position of the connecting mechanism 200 relative to the mover 100, thereby ensuring the connection stability between the connecting mechanism 200 and the mover 100, thereby ensuring the stability of material transportation while ensuring the transportation speed.
