Among them, the plane where the X direction is located intersects with the plane where the Z direction is located and they are not coplanar, the plane where the X direction is located intersects with the plane where the Y direction is located and they are not coplanar, and the plane where the Y direction is located intersects with the plane where the Z direction is located and they are not coplanar.

[0036] According to the first aspect of an embodiment of the present application, a conveying device is provided, comprising a first conveying mechanism 1, a second conveying mechanism 2 and a magnetically driven conveying mechanism 3; the first conveying mechanism 1 transfers materials along the X direction; the second conveying mechanism 2 and the first conveying mechanism 1 are spaced apart along the Z direction, and the second conveying mechanism 2 transfers materials along the X direction; the magnetically driven conveying mechanism 3 is adjacent to the first conveying mechanism 1 and the second conveying mechanism 2 along the X direction and is located between the first conveying mechanism 1 and the second conveying mechanism 2 in the Z direction, and the conveying end of the magnetically driven conveying mechanism 3 can move cyclically along the Z direction and the first direction to transfer materials between the first conveying mechanism 1 and the second conveying mechanism 2.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the conveying device includes a first conveying mechanism 1, a second conveying mechanism 2 and a magnetic drive conveying mechanism 3.

[0038] Among them, the first transport mechanism 1 and the second transport mechanism 2 are arranged at intervals along the Z direction. The first transport mechanism 1 can move materials along the X direction, and the second transport mechanism 2 can transfer materials along the X direction. The conveying direction of the first transport mechanism 1 is opposite to the conveying direction of the second transport mechanism 2.

[0039] The magnetically driven transport mechanism 3 is arranged adjacent to the first transport mechanism 1 and the second transport mechanism 2 along the X direction, that is, the magnetically driven transport mechanism 3 is arranged on one side of the first transport mechanism 1 and the second transport mechanism 2, and the magnetically driven transport mechanism 3 is located between the first transport mechanism 1 and the second transport mechanism 2 in the Z direction. The magnetically driven transport mechanism 3 can transfer materials on the first transport mechanism 1 to the second transport mechanism 2, or the magnetically driven transport mechanism 3 can transfer materials from the second transport mechanism 2 to the first transport mechanism 1.

[0040] It is further explained that the conveying end of the magnetically driven transport mechanism 3 can move circularly along the Z direction and the first direction; specifically, the Z direction and the first direction can form a closed moving path, the conveying end can move circularly in the Z direction and the first direction, and when the conveying end moves in the Z direction, the magnetically driven transport mechanism 3 can move the material of the first transport mechanism 1 to the second transport mechanism 2.

[0041] If the second section 342 and the fourth section 344 are in an arc shape, the conveying end moves counterclockwise or clockwise on the second section 342. For the first direction, please refer to the attached Figure 5 The conveying end moves counterclockwise or clockwise on the fourth section 344. For the first direction, please refer to the attached Figure 6 The first direction is the moving direction of the conveying end on the second section 342 and / or the fourth section 344.

[0042] If the second section 342 and the fourth section 344 are in a straight line, the first direction is the X direction.

[0043] Compared with the belt transport used in the prior art, the embodiment of the present application adopts a magnetic drive transport mechanism 3 to transfer materials between the first transport mechanism 1 and the second transport mechanism 2. It has a simple structure, higher stability and higher efficiency.

[0044] Among them, the magnetic-driven transport mechanism 3 generates a magnetic force after the stator is energized, and the mover moves under the action of the magnetic force, so that the output end of the magnetic-driven transport mechanism 3 can move materials between the first transport mechanism 1 and the second transport mechanism 2.

[0045] In an optional embodiment, the magnetically driven transport mechanism 3 includes a stator assembly 31, a guide rail 34, at least one movable assembly 32 and at least one first carrier 33, the guide rail 34 is arranged around the stator assembly 31, the movable assembly 32 is slidably connected to the guide rail 34, the movable assembly 32 can move cyclically along the guide rail 34, the first carrier 33 is arranged on the movable assembly 32, and the first carrier 33 is used to place materials.

[0046] like Figure 1 , Figure 3 and Figure 4As shown, the magnetically driven transport mechanism 3 includes a stator assembly 31 , a guide rail 34 , at least one mover assembly 32 and at least one first carrier 33 .

[0047] Among them, the guide rail 34 is arranged around the stator assembly 31, the movable assembly 32 is slidably connected to the guide rail 34, and the first carrier 33 is arranged on the movable assembly 32. When the movable assembly 32 moves along the guide rail 34, the movable assembly 32 can move circularly along the Z direction and the first direction around the stator assembly 31, and can also drive the material on the first carrier 33 to move along the Z direction, thereby transferring the material located on the first transport mechanism 1 to the second transport mechanism 2, and then moving idly along the first direction and the Z direction to the first transport mechanism 1.

[0048] To further explain, the working principle of the magnetic drive transport mechanism 3 is that the stator assembly 31 generates a rotating magnetic field after being energized, and the magnetic field generated by the stator assembly 31 interacts with the mover assembly 32 to generate a force in the mover assembly 32, so that the mover assembly 32 moves around the direction of the magnetic field.

[0049] In an optional embodiment, the number of the movable subassemblies 32 is multiple, and the multiple movable subassemblies 32 are arranged at intervals along the guide rail 34. The number of the first carriers 33 is multiple, and one first carrier 33 is connected to the corresponding movable subassembly 32. The number of movable subassemblies 32 is the same as the number of first carriers 33, and one first carrier 33 is connected to one movable subassembly 32. By providing multiple first carriers 33, the interval time between transporting two adjacent materials can be shortened, thereby improving the transportation efficiency.

[0050] In an optional implementation, the mover assembly 32 includes a sliding member and a mover block, the sliding member is slidably connected to the guide rail 34, and the mover block is connected to the sliding member.

[0051] To further explain, the mover assembly 32 includes a sliding member and a mover block. The sliding member is slidably connected to the guide rail 34, and the mover block is connected to the sliding member. When the mover block moves around the stator assembly 31 under the action of electromagnetic force, the sliding member will move along the guide rail 34, so that the mover block can move along the guide rail 34 to provide guidance for the movement of the first carrier 33.

[0052] To further explain, the first carrier 33 may be connected to the mover block or to the sliding member.

[0053] In an optional embodiment, the guide rail 34 includes a first section 341, a second section 342, a third section 343 and a fourth section 344 which are connected in sequence end to end, an accommodating space 345 is formed in the guide rail 34, the stator assembly 31 is arranged in the accommodating space 345, the first section 341 and the third section 343 are arranged at intervals along the X direction, the second section 342 and the fourth section 344 are arranged at intervals along the Z direction, and the first section 341 is arranged adjacent to the first transport mechanism 1 and the second transport mechanism 2.

[0054] like Figure 4 , Figure 5 and Figure 6 As shown, the guide rail 34 includes a first section 341, a second section 342, a third section 343 and a fourth section 344. The first section 341, the second section 342, the third section 343 and the fourth section 344 are connected in sequence, and the guide rail 34 forms a continuous annular structure, and an accommodation space 345 is formed in the guide rail 34. The stator assembly 31 is arranged in the accommodation space 345. Since a rotating magnetic field is formed when the stator assembly 31 is energized, when the mover assembly 32 is slidably connected to the guide rail 34, the mover assembly 32 can move along the guide rail 34.

[0055] Further description, the first section 341 and the third section 343 are arranged at intervals along the X direction, the second section 342 and the fourth section 344 are arranged along the Z direction, the second section 342 connects the first section 341 and the third section 343 at one end of the first section 341 and the third section 343, and the fourth section 344 connects the first section 341 and the third section 343 at the other end of the first section 341 and the third section 343. Among them, the first transport mechanism 1 and the second transport mechanism 2 are arranged at intervals along the Z direction. If the first transport mechanism 1 is located above the second transport mechanism 2 in the Z direction, then when the first carrier 33 is in the first section 341, the material is loaded at the first transport mechanism 1, the first carrier 33 moves along the first section 341 toward the second transport mechanism 2, and at the second transport mechanism 2, the material is transferred to the second transport mechanism 2, and the first carrier 33 will continue to transfer along the second section 342, the third section 343 and the fourth section 344, and finally move to the first section 341, and repeat the above process. In this embodiment, the first carrier 33 is loaded with materials only when it is in the first section 341, and the other parts are empty. When the first carrier 33 is in the first section 341, the materials are placed on the first carrier 33, and the materials are located on the first carrier 33, that is, the bearing surface of the first carrier 33 faces upward, so it can support the materials. When the first carrier 33 rotates to the second section 342, the bearing surface of the first carrier 33 faces downward, so it cannot support the materials. Therefore, the first carrier 33 completes the loading and unloading of materials in the first section 341, and the second section 342, the third section 343 and the fourth section 344 are in order to make the first carrier 33 circulate and move back to the first section 341.

[0056] In an optional embodiment, the second section 342 is in an arc shape, the second section 342 includes a first connection end 3421 and a second connection end 3422, the first connection end 3421 is connected to the first section 341, the tangent of the first connection end 3421 coincides with the extension line of the first section 341 in the Z direction, the second connection end 3422 is connected to the third section 343, the tangent of the second connection end 3422 coincides with the extension line of the third section 343 in the Z direction; and / or, the fourth section 344 is in an arc shape, the fourth section 344 includes a third connection end 3431 and a fourth connection end 3432, the third connection end 3431 is connected to the first section 341, the tangent of the third connection end 3431 coincides with the extension line of the first section 341 in the Z direction, the fourth connection end 3432 is connected to the third section 343, and the tangent of the fourth connection end 3432 coincides with the extension line of the third section 343 in the Z direction.

[0057] In a specific implementation, the second section 342 is in an arc shape.

[0058] In another specific implementation, the fourth section 344 is in an arc shape.

[0059] In another specific implementation, the second section 342 is in an arc shape, and the fourth section 344 is in an arc shape. This implementation is taken as an example for description.

[0060] Specifically, the second section 342 is in the shape of an arc, that is, the sliding trajectory of the movable subassembly 32 on the second section 342 is an arc, and the second section 342 includes a first connecting end 3421 and a second connecting end 3422, and the first connecting end 3421 and the second connecting end 3422 are spaced apart along the X direction, the first connecting end 3421 is connected to the first section 341, and the second connecting end 3422 is connected to the third section 343; wherein, the tangent of the first connecting end 3421 coincides with the extension line of the first section 341 in the Z direction, and the tangent of the second connecting end 3422 coincides with the extension line of the third section 343 in the Z direction, so that the movable subassembly 32 can smoothly transition between the first section 341 and the second section 342, and smoothly transition between the second section 342 and the third section 343, thereby improving the movement stability of the movable subassembly 32.

[0061] The fourth section 344 is in the shape of an arc, that is, the sliding trajectory of the movable subassembly 32 on the fourth section 344 is an arc, and the fourth section 344 includes a third connecting end 3431 and a fourth connecting end 3432, and the third connecting end 3431 and the fourth connecting end 3432 are spaced apart along the X direction, the third connecting end 3431 is connected to the first section 341, and the fourth connecting end 3432 is connected to the third section 343; wherein, the tangent of the third connecting end 3431 coincides with the extension line of the first section 341 in the Z direction, and the tangent of the fourth connecting end 3432 coincides with the extension line of the third section 343 in the Z direction, so that the movable subassembly 32 can smoothly transition between the fourth section 344 and the first section 341, and smoothly transition between the third section 343 and the fourth section 344, thereby improving the movement stability of the movable subassembly 32.

[0062] In an optional embodiment, the second transport mechanism 2 includes a conveyor belt 22 and at least one second carrier 21, the second carrier 21 is arranged on the conveyor belt 22, and the conveyor belt 22 partially overlaps with the first carrier 33 in the Z direction; the first section 341 is close to the first transport mechanism 1 and the second transport mechanism 2 in the X direction relative to the third section 343; the first carrier 33 is provided with an avoidance groove 331, the first carrier 33 moves along the Z direction in the first section 341, and the second carrier 21 can pass through the avoidance groove 331 to lift the material located on the first carrier 33.

[0063] like Figure 2 As shown, the second transport mechanism 2 includes a conveyor belt 22 and at least one second carrier 21 .

[0064] The second carrier 21 is disposed on the conveyor belt 22 . If the second transport mechanism 2 includes a plurality of second carriers 21 , the plurality of second carriers 21 are disposed on the conveyor belt 22 at intervals along the X direction.

[0065] To further illustrate, the conveyor belt 22 moves along the X direction, and a portion of the second transport mechanism 2 on a side close to the magnetic-driven transport mechanism 3 extends into the magnetic-driven transport mechanism 3, so that a portion of the conveyor belt 22 on a side of the second transport mechanism 2 close to the magnetic-driven transport mechanism 3 will overlap with the first carrier 33 in the Z direction; an avoidance groove 331 is provided on the first carrier 33, and when the first carrier 33 moves along the first section 341 from the first transport mechanism 1 to the second transport mechanism 2, when passing through the second transport mechanism 2, the second carrier 21 on the conveyor belt 22 will pass through the avoidance groove 331, so that the first carrier 33 passes through the second transport mechanism 2. Therefore, the first carrier 33 loads the material at the first transport mechanism 1, and the first carrier 33 moves along the Z direction from the first transport mechanism 1 to the second transport mechanism 2. When passing through the second transport mechanism 2, the second carrier 21 can pass through the avoidance groove 331 to lift the material on the first carrier 33, thereby transferring the material on the magnetic-driven transport mechanism 3 to the second transport mechanism 2; with this embodiment, a separate transfer mechanism is no longer required to transfer the material on the magnetic-driven transport mechanism 3 to the second transport mechanism 2, which can reduce costs and reduce floor space.

[0066] In an optional implementation, the second carrier 21 is provided with a suction hole 211 .
