DETAILED DESCRIPTION

[0042] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0043] The following describes a driving mechanism 20 for a magnetic levitation transmission device 100 according to an embodiment of the present application with reference to the accompanying drawings.

[0044] 1-3 , a magnetic levitation transmission device 100 according to an embodiment of the present application includes a track member 10 and a mover 14. The mover 14 is movably disposed on the track member 10 along the extension direction of the track member 10. The track member 10 includes a linear track 12 and a curved track 13 arranged along the extension direction of the track member. A drive mechanism 20 is used to drive the mover 14 to move on the curved track 13. The mover 14 can move along the extension direction of the track member 10, which facilitates the implementation of automated transmission and transfer functions. Workpieces to be transferred, such as pole pieces, can be fixed to the mover 14 and follow the mover 14 along the track member 10 to a corresponding position, thereby improving transmission efficiency, safety, and accuracy.

[0045] The drive mechanism 20 includes a drive motor 22 and a turntable 21. The turntable 21 is rotatably mounted on the curved track 13. The drive mechanism 20 is connected to the turntable 21 to drive its rotation. The turntable 21 is detachably connected to the mover 14. When the mover 14 is on the curved track 13, the mover 14 is connected to the turntable 21 to drive the mover 14 along the circumference of the curved track 13. When the mover 14 is on the straight track 12, the mover 14 is disconnected from the turntable 21.

[0046] In the related art, when the mover 14 on the magnetic levitation transmission device 100 moves from the linear track 12 to the curved track 13, the motion state of the mover 14, such as speed and acceleration, changes dramatically, resulting in poor stability of the mover 14 on the curved track 13. By providing a drive mechanism 20, when the mover 14 is on the curved track 13, the mover 14 is connected to the turntable 21. The drive motor 22 of the drive mechanism 20 can drive the turntable 21 to rotate, thereby providing power to the mover 14 and driving the mover 14 to move circumferentially along the curved track 13, thereby improving the stability of the mover 14 on the curved track 13.

[0047] According to the driving mechanism 20 of the embodiment of the present application, when the mover 14 of the magnetic levitation transmission device 100 is located on the turning track 13, the driving mechanism 20 can provide power to the mover 14 and drive the mover 14 to move circumferentially along the turning track 13, thereby improving the stability of the mover 14 moving on the turning track 13.

[0048] 1-3 , according to some embodiments of the present application, one of the driving mechanism 20 and the mover 14 is provided with a mating block 15 and the other is provided with a mating groove 210. The driving mechanism 20 may be provided with the mating block 15 and the mover 14 may be provided with the mating groove 210; or the mover 14 may be provided with the mating block 15 and the driving mechanism 20 may be provided with the mating groove 210.

[0049] Among them, when the mover 14 is located on the turning track 13, the mating block 15 is accommodated in the mating groove 210 to connect the mover 14 with the driving mechanism 20, and the driving mechanism 20 drives the mover 14 to move circumferentially along the turning track 13; when the mover 14 is located on the straight track 12, the mating block 15 is disengaged from the mating groove 210 to disconnect the mover 14 from the driving mechanism 20. After the mover 14 moves from the straight track 12 to the turning track 13, the movement state of the mover 14 changes dramatically, resulting in a relatively unstable movement of the mover 14 on the turning track 13. By providing a matching block 15 on one of the driving mechanism 20 and the mover 14 and a matching groove 210 on the other, when the mover 14 is located on the turning track 13, the matching block 15 is accommodated in the matching groove 210 to connect the mover 14 with the driving mechanism 20, so that the driving mechanism 20 can drive the mover 14 to move circumferentially along the turning track 13, thereby enabling the mover 14 to move more smoothly on the turning track 13, thereby improving the stability and safety of the mover 14 moving on the track member 10.

[0050] 1 to 3 , according to some embodiments of the present application, a mating groove 210 is formed on the outer peripheral wall of the turntable 21, and a mating block 15 is provided on the mover 14, so that the mating block 15 of the mover 14 can be mated with the mating groove 210 at a corresponding position of the outer peripheral wall of the turntable 21, thereby facilitating the connection between the mover 14 and the driving mechanism 20. At the same time, the mating block 15 of the mover 14 can be disengaged from the mating groove 210 of the turntable 21 at a relevant position of the outer peripheral wall of the turntable 21, thereby facilitating the disconnection between the mover 14 and the driving mechanism 20.

[0051] 1-3 , according to some embodiments of the present application, the mating groove 210 is a notch formed on the outer peripheral wall of the rotary disk 21. The mating groove 210 is a notch formed on the outer peripheral wall of the rotary disk 21, which makes the shape of the mating groove 210 relatively simple and facilitates the processing and manufacture of the mating groove 210.

[0052] 1 to 3 , according to some embodiments of the present application, the mating groove 210 is an arcuate groove, and the mating block 15 is cylindrical. When the mover 14 is located on the turning track 13, the mating block 15 of the mover 14 is accommodated in the mating groove 210 of the turntable 21. The mating groove 210 is an arcuate groove, and the mating block 15 is cylindrical, which can facilitate the mating of the mating groove 210 and the mating block 15. At the same time, it can make the mating groove 210 and the mating block 15 have a larger connection area, making the mating of the mating groove 210 and the mating block 15 more stable. In addition, the mating groove 210 is an arcuate groove, and the mating block 15 is cylindrical, which can facilitate the mating of the mating block 15 from the mating groove 210.

[0053] 1-3 , according to some embodiments of the present application, the mating groove 210 is a notch formed on the outer peripheral wall of the rotary disk 21. The mating groove 210 is an arcuate groove, and the mating block 15 is cylindrical. This makes the shape of the mating groove 210 relatively simple, facilitating its processing and fabrication. Furthermore, the arcuate groove 210 and the cylindrical mating block 15 facilitate the mating of the mating groove 210 and the mating block 15. Furthermore, the mating groove 210 and the mating block 15 have a larger connection area, resulting in a more stable mating between the mating groove 210 and the mating block 15.

[0054] 1-3 , according to some embodiments of the present application, a plurality of mating grooves 210 are formed on the turntable 21, and the plurality of mating grooves 210 are arranged at intervals along the circumference of the turntable 21. By providing a drive motor 22 and the turntable 21, the plurality of mating grooves 210 are formed on the turntable 21. When the mover 14 is located on the turning track 13, the mating blocks 15 of the mover 14 are accommodated in the mating grooves 210. The drive motor 22 drives the turntable 21 to rotate about the rotation axis, so that the turntable drives the mover 14 to move circumferentially along the turning track 13. Furthermore, the plurality of mating grooves 210 are arranged at intervals along the circumference of the turntable 21, and the plurality of mating grooves 210 correspond one-to-one with the mating blocks 15 of the plurality of movers 14. This allows the turntable 21 to simultaneously drive the plurality of movers to move circumferentially along the turning track 13, while maintaining a sufficient safety distance between the plurality of movers 14, thereby preventing collisions between the plurality of movers 14 on the turning track 13.

[0055] It should be noted that the term “plurality” in this application refers to two or more.

[0056] 3-5 , according to some embodiments of the present application, the mover 14 includes a support plate 16 and two side plates 17 . The support plate 16 is located on the track member 10 and is used to support the workpiece. The two side plates 17 are connected to the support plate 16 on both sides of the axial direction of the track member 10 . By providing the support plate 16 , the workpiece can be placed on the support plate 16 and follow the mover 14 to move to the corresponding position along the circumferential direction of the track member 10 , which can improve the transfer efficiency and improve the safety and accuracy of the transfer. At least one side plate 17 is provided with a mating block 15 at one end away from the support plate 16, that is, the mating block 15 can be provided at one end of one side plate 17 away from the support plate 16, or the mating blocks 15 can be provided at one end of both side plates 17 away from the support plate 16. For example, referring to Figure 2, the mating blocks 15 are provided at one end of the two side plates 17 of the mover 14 away from the support plate 16, and the driving mechanism 20 includes two turntables 21. The two turntables 21 of the driving mechanism 20 are located on both axial sides of the turning track 13, and the two mating blocks 15 of the mover 14 are mated with the mating grooves 210 of the two turntables 21.

[0057] 1-5 , a magnetic levitation transmission device 100 according to an embodiment of the second aspect of the present application includes a track member 10 and a drive mechanism 20. When a mover 14 is located on a linear track 12, the linear track 12 drives the mover 14 to move along the extension direction of the linear track 12 via magnetic levitation. As the mover 14 moves along the linear track 12, the mover 14 disengages from the drive mechanism 20. A magnet 18 is provided on the mover 14, and the linear track 12 drives the mover 14 to move via magnetic levitation. For example, a linear stator 19 of the linear track 12 is provided with a coil. When energized, the coil forms a magnetic field that interacts with the magnet 18 on the mover 14, propelling the mover 14 along the linear track 12.

[0058] Furthermore, the linear track 12 drives the mover 14 via magnetic levitation, enabling the mover 14 to achieve a higher transport speed and higher conveying accuracy on the linear track 12. When the mover 14 is on the curved track 13, the drive mechanism 20 is provided, and the mover 14 is connected to the drive mechanism 20. Driven by the drive mechanism 20, the mover 14 moves along the curved track 13. This prevents the mover 14 from experiencing a reduced magnetic field after reaching the curved track 13, which could result in lower speed and acceleration during movement of the mover 14 on the curved track 13.

[0059] The turntable 21 is located on at least one side of the axial direction of the turning track 13. This means the turntable 21 can be located on one side of the axial direction of the turning track 13, or on both sides of the axial direction of the turning track 13. The rotation axis of the turntable 21 coincides with the axis of the turning track 13. When the mover 14 is located on the turning track 13, the mating block 15 of the mover 14 is accommodated in the mating groove 210. The drive motor 22 drives the turntable 21 to rotate about the rotation axis. The rotation axis of the turntable 21 coincides with the axis of the turning track 13, allowing the turntable to drive the mover 14 to rotate about the axis of the turning track 13.

[0060] According to the magnetic levitation transmission device 100 of the embodiment of the present application, by providing the above-mentioned driving mechanism 20, when the mover 14 of the magnetic levitation transmission device 100 is located on the turning track 13, the driving mechanism 20 can provide power to the mover 14 and drive the mover 14 to move circumferentially along the turning track 13, thereby improving the stability of the mover 14 moving on the turning track 13.

[0061] 3-5 , according to some embodiments of the present application, the drive motor 22 is located on one axial side of the turning track 13. The drive motor 22 is disposed on one axial side of the turning track 13, which can fully utilize the space on the axial side of the turning track 13, making the overall structure of the drive mechanism 20 more compact.

[0062] 3-5 , according to some embodiments of the present application, the drive mechanism 20 includes two turntables 21 located on opposite axial sides of the turning track 13, and the drive motor 22 is located on the axial side of one of the turntables 21 away from the turning track 13. The drive mechanism 20 is provided with two turntables 21 located on opposite axial sides of the turning track 13, which fully utilizes the space on both axial sides of the turning track 13 and makes the overall structure of the drive mechanism 20 relatively compact.

[0063] In addition, by providing two turntables 21, the connection between the matching groove 210 and the driving mechanism 20 can be made more flexible. For example, the two turntables 21 are each formed with a plurality of matching grooves 210, and the plurality of matching grooves 210 are arranged at intervals along the circumference of the turntable 21. A matching block 15 can be provided on the mover 14, and the matching blocks 15 on the plurality of movers 14 are located on the same axial side of the turning track 13 and cooperate with the matching groove 210 of the turntable 21 located on the same axial side of the turning track 13; a matching block 15 can be provided on the mover 14, and the matching blocks 15 on the plurality of movers 14 are located on the same axial side of the turning track 13. 5 are respectively located on both sides of the axial direction of the turning track 13. The matching blocks 15 of a part of the movers 14 match with the matching grooves 210 of the rotary disk 21 located on one side of the axial direction of the turning track 13, and the matching blocks 15 of the other part of the movers 14 match with the matching grooves 210 of the rotary disk 21 located on the other side of the axial direction of the turning track 13. The mover 14 is symmetrically provided with two matching blocks 15 along both sides of the axial direction of the turning track 13. The matching blocks 15 of the mover 14 located on both sides of the axial direction of the turning track 13 match with the matching grooves 210 of the rotary disk 21 located on both sides of the axial direction of the turning track 13.

[0064] 1 to 5 , the track member 10 is annular and includes two linear tracks 12 and two curved tracks 13. The two linear tracks 12 are arranged opposite to each other and spaced apart. The two curved tracks 13 are located on opposite sides of the two linear tracks 12. The two ends of each curved track 13 in the length direction are respectively connected to the two linear tracks 12. The structure of the track member 10 is relatively simple. For example, the outer peripheral wall of the track member 10 has an annular track 11 extending along the circumferential direction of the track member 10. The annular track 11 includes two linear tracks 12 and two curved tracks 13. The two linear tracks 12 are arranged between the two curved tracks 13. The two linear tracks 12 can be arranged in parallel. One end of the two linear tracks 12 is respectively connected to the two ends of one of the curved tracks 13, and the other end of the two linear tracks 12 is respectively connected to the two ends of the other curved track 13. The shape is relatively simple, the processing and manufacturing difficulty is relatively low, and the mover 14 can move relatively smoothly on the annular track 11.

[0065] There are two drive mechanisms 20, and the drive motors 22 of the two drive mechanisms 20 are located on the same side of the track member 10. This fully utilizes the space on both sides of the track member 10 in the axial direction, making the overall structure of the magnetic levitation transmission device 100 more compact. Furthermore, the axial dimension of the magnetic levitation transmission device 100 in the curved track 13 can be reduced.

[0066] Furthermore, in related art, when the magnetic levitation transmission device 100 is used vertically, that is, when the axis of the curved track 13 of the circular track 11 is parallel to the ground or operating table, and the linear track 12 is parallel to the horizontal plane, if both the linear track 12 and the curved track 13 use magnetic levitation to drive the mover 14, while the mover 14 remains on the curved track 13, the magnetic levitation needs to continue to work to overcome the gravity of the mover 14 itself, resulting in significant power consumption and a long-term stay that can easily cause the track member 10 to overheat. Furthermore, when the magnetic levitation transmission device 100 is powered off, the movers 14 on the curved track 13 will slide down the curved track 13 under their own gravity, which can easily cause collisions between movers 14 and reduce safety.

[0067] By providing the drive mechanism 20, the operating state of the drive motor 22 can be controlled according to the specific usage of the magnetic levitation transmission device 100. When the drive motor 22 is controlled to stop rotating, the turntable 21 stops rotating, and the mating block 15 of the mover 14 is accommodated in the mating groove 210 of the turntable 21. The mover 14 can remain relatively stable on the curved track 13, and the magnetic levitation transmission device 100 does not require additional work to overcome the gravity of the mover 14. In addition, by providing the drive mechanism 20, it is possible to prevent the mover 14 located on the curved track 13 from sliding down the curved track 13 due to its own gravity after the magnetic levitation transmission device 100 is powered off, thereby improving the safety and flexibility of the magnetic levitation transmission device 100.

[0068] The following describes a driving mechanism 20 for a magnetic levitation transmission device 100 according to other embodiments of the present application with reference to the accompanying drawings.

[0069] 6-7 , the driving mechanism 20 according to the embodiment of the present application is used in the magnetic levitation transmission device 100 . The magnetic levitation transmission device 100 includes an arc-shaped turning track 13 and a mover 14 movably provided on the turning track 13 .

When the insertion rod 23 moves from the portion of the cam disk 24 with the protrusion 241 to the portion without the protrusion 241, the elastic member 25, under the action of the elastic force, drives the insertion rod 23 to move along the axial direction of the rotary disk 21 toward the direction away from the turning track 13, and causes the insertion rod 23 to disengage from the insertion hole 141 of the mover 14. In addition, by providing the elastic member 25 , the elastic member 25 can, under the action of elastic force, enable the insertion rod 23 to abut against the end of the cam plate 24 facing the rotary plate 21 .

[0084] 9 and 11 , according to some embodiments of the present application, the driving mechanism 20 includes a rotary disk 21, a driving motor 22, an insert rod 23, a cam plate 24, an elastic member 25, a wall panel 26, a fixed shaft 27, a first gear 28, and a second gear 29. The rotary disk 21 includes a first rotary disk 211 and a second rotary disk 212. The insert rod 23 is movably disposed on the first rotary disk 211 and the second rotary disk 212. The elastic member 25 is located between the first rotary disk 211 and the second rotary disk 212. The rotary disk 21 is provided with a rotary shaft 214, which is disposed within the turning track 13 and connected to the driving motor 22. One end of the fixed shaft 27 is connected to the cam plate 24. The fixed shaft 27 is disposed within the rotary shaft 214 and the other end is connected to the wall panel 26. The cam plate 24 has a protrusion 241 on its end facing the rotary disk 21.

[0085] The driving motor 22 is running, which can drive the first gear 28 connected to the output shaft of the driving motor 22 to rotate, and the first gear 28 can drive the second gear 29 meshing with the first gear 28 to rotate, and the second gear 29 can drive the rotary shaft 214 connected to the rotating shaft of the second gear 29 to rotate.

[0086] 6-11 , a magnetic levitation transmission device 100 according to other embodiments of the present application includes a track member 10, a mover 14, and the aforementioned drive mechanism 20. The track member 10 has a track, which includes a linear track 12 and a curved track 13 connected to each other. The linear track 12 is provided with a linear stator, and the curved track 13 is a circular track. The mover 14 is movably disposed on the track, and a plurality of movers 14 are spaced apart along the length of the track. The plurality of movers 14 are spaced apart along the circumferential direction of the annular track 11, so that there is a sufficient safety distance between adjacent movers 14, which can reduce or avoid the occurrence of collisions between two adjacent movers 14.

[0087] The mover 14 is equipped with a magnet, and the linear track 12 drives the mover 14 via magnetic levitation. The drive mechanism 20 is arranged opposite the curved track 13. The turntable 21 is located on one side of the curved track 13, and its rotation axis coincides with the axis of the curved track. The mover 14 is provided with an insert plate on the side facing the turntable 21, and the insert plate has a socket 141. When the mover 14 is located on the curved track 13, the insert rod 23 extends into the socket 141. When the mover 14 is located on the linear track 12, the insert rod 23 is disengaged from the socket 141. The linear track 12 drives the mover 14 via magnetic levitation. When the mover 14 moves on the linear track 12, the insertion rod 23 disengages from the insertion hole 141, and the mover 14 disengages from the driving mechanism 20. A magnet is provided on the mover 14, and the linear track 12 drives the mover 14 to move by magnetic levitation. For example, the linear stator of the linear track 12 is provided with a coil. When the coil is energized, a magnetic field is formed, which can interact with the magnet on the mover 14 to push the mover 14 along the linear track 12. In addition, the linear track 12 drives the mover 14 to move by magnetic levitation, which can enable the mover 14 to have a higher transport speed and higher conveying accuracy on the linear track 12.

[0088] When the mover 14 moves on the turning track 13, the insertion rod 23 extends into the insertion hole 141, and the mover 14 cooperates with the driving mechanism 20 and moves along the turning track 13 under the drive of the driving mechanism 20. This can prevent the mover 14 from being subjected to a smaller magnetic field after moving to the turning track 13, thereby causing the mover 14 to have a lower speed and acceleration during the movement of the turning track 13.

[0089] Optionally, two annular guide rails 131 can be symmetrically arranged on both sides of the axial direction of the track member 10, and the mover 14 is provided with a matching groove that matches the two guide rails 131. By setting the guide rails 131, the matching groove of the mover 14 matches the guide rails 131, and the guide rails 131 can support and guide the mover 14, thereby improving the stability of the movement of the mover 14.

[0090] Optionally, the linear track 12 may also provide support force for the mover 14 through magnetic levitation to ensure the stability of the movement of the mover 14 .

[0091] According to other embodiments of the magnetic levitation transmission device 100 of the present application, by setting the above-mentioned driving mechanism 20, when the mover 14 is located on the turning track 13, the insertion rod 23 of the driving mechanism 20 can be extended into the insertion hole 141 of the mover 14, thereby driving the mover 14 to move on the turning track 13, which can improve the stability of the mover 14 moving on the turning track 13. 1-3 , according to some embodiments of the present application, there are two linear rails 12 that are opposite to each other and spaced apart, there are two turning rails 13 that are spaced apart, the linear rail 12 is located between the two turning rails 13, the two linear rails 12 and the two turning rails 13 are connected end to end to form a ring, and the driving mechanisms 20 are two correspondingly arranged corresponding to the two turning rails 13. The structure is relatively simple, the processing and manufacturing difficulty is relatively low, and the mover 14 can move more smoothly on the annular rail 11. For example, the rail is an annular rail 11, and the annular rail 11 includes two linear rails 12 and two turning rails 13. The two linear rails 12 are arranged between the two turning rails 13, and the two linear rails 12 can be arranged in parallel. One end of the two linear rails 12 is respectively connected to the two ends of one of the turning rails 13, and the other end of the two linear rails 12 is respectively connected to the two ends of the other turning rail 13. The mover 14 of the annular track 11 can move along the circumferential direction of the annular track 11, which is conducive to realizing functions such as automated transportation and transfer. The workpiece that needs to be transferred, such as the pole piece, can be fixed to the mover 14 and follow the mover 14 to move along the circumferential direction of the annular track 11 to the corresponding position, which can improve the transfer efficiency and improve the safety and accuracy of the transfer.

[0092] Furthermore, in related art, when the magnetic levitation transmission device 100 is used vertically, that is, when the axis of the curved track 13 of the circular track 11 is parallel to the ground or operating table, and the linear track 12 is parallel to the horizontal plane, if both the linear track 12 and the curved track 13 use magnetic levitation to drive the mover 14, while the mover 14 remains on the curved track 13, the magnetic levitation needs to continue to work to overcome the gravity of the mover 14 itself, resulting in significant power consumption and a long-term stay that can easily cause the track member 10 to overheat. Furthermore, when the magnetic levitation transmission device 100 is powered off, the mover 14 located on the curved track 13 will slide down the curved track 13 under its own gravity, which can easily cause collisions between movers 14 and reduce safety.

[0093] By providing the drive mechanism 20, during the use of the magnetic levitation transmission device 100, the working state of the drive motor 22 can be controlled according to the specific use situation. When the mover 14 needs to stay on the turning track 13, the drive motor 22 stops rotating, the turntable 21 and the insertion rods 23 arranged along the circumference of the turntable 21 will stop rotating, and the insertion rods 23 are inserted into the insertion holes 141 of the mover, so that the mover 14 can stay on the turning track 13 more stably, and the transfer device 100 does not need to make additional work to overcome the gravity of the mover 14. In addition, by providing the drive mechanism 20, it is possible to prevent the mover 14 located on the turning track 13 from sliding down the turning track 13 under the action of its own gravity after the transfer device 100 is powered off, thereby improving the safety and flexibility of the transfer device 100.
