However, due to space limitations in actual production, material workstations need to be on multiple planes in the vertical space. Therefore, the magnetic levitation mover needs to be able to reach any direction in any plane in the space. Utility Model Content

[0003] An embodiment of the present application provides a magnetic drive conveying system, which can transfer movers in different planes at different heights.

[0004] The magnetic drive conveying system includes a base, a docking assembly, a mover and multiple stator rails. The docking assembly includes a motion structure and a docking stator.

[0005] Based on the magnetic drive conveying system of the embodiment of the present application, when the mover needs to be transferred from a stator track to another stator track, the motion structure drives the docking stator to move along the height direction of the base and drives the docking stator to rotate, so that the docking stator is connected to the stator track with the mover. Under the drive of the stator track, the mover moves from the stator track to the transfer stator. Then the motion structure drives the docking stator to move along the height direction of the base and drives the docking stator to rotate again, so that the docking stator is connected to the stator track of the mover to be received. Under the drive of the transfer stator, the mover moves from the transfer stator to the stator track of the mover to be received.

[0006] In some embodiments of the present application, the motion structure includes a lifting module and a rotating module, the lifting module is used to drive the docking stator to move along the height direction of the base; the rotating module is installed on the lifting module, the docking stator is installed on the rotating module, and the rotating module is used to drive the docking stator to rotate.

[0007] Based on the above embodiment, the lifting module drives the rotating module and the docking stator to move along the height direction of the base so that the docking stator and any stator track can be at the same height. The rotating module drives the docking stator to rotate so that the docking stator can be connected to the stator track at the same height.

[0008] In some embodiments of the present application, the rotation module includes a carrier, a rotating member and a first power member, and the carrier is transmission-connected to the lifting module; the rotating member is rotatably mounted on the carrier, and the connecting stator is mounted on the rotating member; the first power member is mounted on the carrier and transmission-connected to the rotating member, and the first power member can drive the rotating member to rotate relative to the carrier.

The lifting module drives the supporting member to move along the height direction of the base. The first power member drives the rotating member to rotate on the supporting member, and the rotating member drives the docking stator to rotate synchronously, so that the docking stator can be connected to any stator track surrounding its circumference to realize the transfer of the mover.

[0010] In some embodiments of the present application, the first power member is configured as a first motor, the rotating member and the first motor are installed on opposite sides of the supporting member, and the output shaft of the first motor passes through the supporting member and is connected to the rotating member.

[0011] Based on the above embodiment, the first motor and the rotating member are installed on both sides of the carrier to prevent the first motor from affecting the rotation angle of the rotating member, so that the rotating member can rotate 360°, ensuring that the docking stator can be connected to any stator track.

[0012] In some embodiments of the present application, both ends of the docking stator protrude from the edge of the rotating member.

[0013] Based on the above embodiment, since the end of the docking stator needs to be connected to the stator track, after the end of the docking stator protrudes from the edge of the rotating member, the influence of the rotating member on the connection between the docking stator and the stator track is avoided.

[0014] In some embodiments of the present application, when the stator track is connected to the docking stator, the guiding direction of the stator track is parallel to the guiding direction of the docking stator.

[0015] Based on the above embodiment, when the stator track is connected to the docking stator, the guiding direction of the nail track is parallel to the guiding direction of the docking stator, ensuring that the mover can move smoothly from the stator track to the docking stator; or the mover can move smoothly from the docking stator to the stator track.

[0016] In some embodiments of the present application, the lifting module includes a first support member, a second support member, a second power member and at least two transmission rods; the first support member and the second support frame are relatively arranged along the height direction of the base; the transmission rod is arranged along the height direction of the base, the transmission rod is threadedly connected to the bearing member, and one end is rotatably connected to the first support member, and the other end is rotatably connected to the second support member; the second power member is transmission-connected to the transmission rod, and can drive the transmission rod to rotate around its own axis, and the second power member is installed on the first support member or the second support member.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] At present, the motion trajectory of the magnetic levitation conveyor line is basically that the mover runs in a straight line along the guide rail within a plane, or switches between the upper and lower planes through modules. However, due to space limitations in actual production, material workstations need to be on multiple planes in the vertical space. Therefore, the magnetic levitation mover needs to be able to reach any direction in any plane in the space.

[0031] To solve the above technical problems, please refer to Figures 1 to 3 As shown, an embodiment of the present application proposes a magnetic drive conveying system, which can transfer the mover 40 in different planes at different heights.

[0032] Please refer to Figures 1 to 2As shown, the magnetic drive conveying system includes a base 10, a docking assembly 20, a mover 40 and a plurality of stator rails 30. The docking assembly 20 includes a motion structure 21 and a docking stator 22. The docking stator 22 is installed on the motion structure 21. The motion structure 21 can drive the docking stator 22 to move along the height direction of the base 10 and can drive the docking stator 22 to rotate; the stator rail 30 is installed on the base 10, and the plurality of stator rails 30 are distributed in the height direction of the base 10. The plurality of stator rails 30 are distributed along the circumference of the docking stator 22. The docking stator 22 is at different positions and can be connected to different stator rails 30; the mover 40 is slidably installed on any stator rail 30.

[0033] The base 10 is used to support multiple stator rails 30. The base 10 in the embodiment of the present application can be set as a support frame, which has a lighter weight. At the same time, since the multiple stator rails 30 are distributed along the circumference of the docking stator 22, in some embodiments of the present application, the support frame is surrounded by a receiving space, and the docking assembly 20 is arranged in the receiving space.

[0034] The stator track 30 includes a plurality of stators connected in sequence, each having an armature winding therein. When the stator is energized, the armature winding generates a magnetic field. The mover 40 is provided with a permanent magnet array. When the permanent magnet array is magnetically coupled with the armature winding, the mover 40 moves on the stator track 30 .

[0035] It can be understood that the docking stator 22 is also provided with an armature winding, but the docking stator 22 should be powered off in time after the mover 40 moves from the stator track 30 to the docking stator 22, so that the mover 40 stops moving after moving from the stator track 30 to the docking stator 22, and then the docking stator 22 is driven by the motion structure 21 to move to other stator tracks 30; when the mover 40 moves from the docking stator 22 to the stator track 30, the docking stator 22 is energized to drive the mover 40 to move to the stator track 30.

[0036] Based on the magnetic drive conveying system of the embodiment of the present application, when the mover 40 needs to be transferred from one stator track 30 to another stator track 30, the motion structure 21 drives the docking stator 22 to move along the height direction of the base 10 and drives the docking stator 22 to rotate, so that the docking stator 22 is connected to the stator track 30 with the mover 40. Under the drive of the stator track 30, the mover 40 moves from the stator track 30 to the transfer stator. Then the motion structure 21 drives the docking stator 22 to move along the height direction of the base 10 and drives the docking stator 22 to rotate, so that the docking stator 22 is connected to the stator track 30 to be received by the mover 40. Under the drive of the transfer stator, the mover 40 moves from the transfer stator to the stator track 30 to be received by the mover 40.

[0037] Please refer to Figure 2As shown, in some embodiments of the present application, the motion structure 21 includes a lifting module 211 and a rotating module 212. The lifting module 211 is used to drive the docking stator 22 to move along the height direction of the base 10; the rotating module 212 is installed on the lifting module 211, and the docking stator 22 is installed on the rotating module 212. The rotating module 212 is used to drive the docking stator 22 to rotate. The lifting module 211 drives the rotating module 212 and the docking stator 22 to move along the height direction of the base 10, so that the docking stator 22 and any stator rail 30 can be at the same height. The rotating module 212 drives the docking stator 22 to rotate so that the docking stator 22 can be connected to the stator rail 30 at the same height.

[0038] Please refer to Figure 2 As shown, in some embodiments of the present application, the rotating module 212 includes a supporting member 2121, a rotating member 2122 and a first power member 2123. The supporting member 2121 is transmission-connected to the lifting module 211; the rotating member 2122 is rotatably installed on the supporting member 2121, and the connecting stator 22 is installed on the rotating member 2122; the first power member 2123 is installed on the supporting member 2121 and transmission-connected to the rotating member 2122. The first power member 2123 can drive the rotating member 2122 to rotate relative to the supporting member 2121.

[0039] The supporting member 2121 is connected to the lifting module 211 in a transmission manner. The lifting module 211 drives the supporting member 2121 to move along the height direction of the base 10. The first power member 2123 drives the rotating member 2122 to rotate on the supporting member 2121. The rotating member 2122 drives the docking stator 22 to rotate synchronously, so that the docking stator 22 can be connected to any stator track 30 surrounding its circumference to realize the transfer of the mover 40.

[0040] The supporting member 2121 is used to support the rotating member 2122 and the first power member 2123, and the supporting member 2121 is used to be connected to the lifting module 211 in transmission. In some embodiments of the present application, the supporting member 2121 can be set as a supporting plate, which is sufficient to support the lighter weight of the rotating member 2122, the connecting stator 22 and the first power member 2123.

[0041] The rotating member 2122 is used to install the connecting stator 22 and can rotate relative to the supporting member 2121. In some embodiments of the present application, the rotating member 2122 can be set as a rotating disk, and the rotating disk is set at the center position of the supporting plate. Balls or bearings can be set between the rotating disk and the supporting plate to reduce the friction between the rotating disk and the supporting plate.

[0042] Please refer to Figure 2As shown, in some embodiments of the present application, the first power member 2123 is configured as a first motor, and the rotating member 2122 and the first motor are mounted on opposite sides of the carrier 2121. The output shaft of the first motor passes through the carrier 2121 and is connected to the rotating member 2122. The first motor and the rotating member 2122 are mounted on both sides of the carrier 2121 to prevent the first motor from affecting the rotation angle of the rotating member 2122, allowing the rotating member 2122 to rotate 360 ​​degrees, ensuring that the docking stator 22 can be connected to any stator track 30.

[0043] It can be understood that the rotating member 2122 is rotatably installed on the top wall of the supporting member 2121, and the connecting stator 22 is installed on the top wall of the rotating member 2122 so that the connecting stator 22 can support the mover 40, and the first motor is installed on the bottom wall of the supporting member 2121 to avoid the rotation of the rotating member 2122 and the connecting stator 22.

[0044] Please refer to Figure 2 As shown, in some embodiments of the present application, both ends of the docking stator 22 protrude from the edge of the rotating member 2122. Since the end of the docking stator 22 needs to be connected to the stator track 30, after the end of the docking stator 22 protrudes from the edge of the rotating member 2122, the influence of the rotating member 2122 on the connection between the docking stator 22 and the stator track 30 is avoided.

[0045] In some embodiments of the present application, when the stator rail 30 is connected to the docking stator 22, the guide direction of the stator rail 30 is parallel to the guide direction of the docking stator 22, ensuring that the docking stator 22 and the stator rail 30 are in the same straight line after the docking stator 22 and the stator rail 30 are connected, and the mover 40 can slide smoothly from the docking stator 22 to the stator rail 30, or from the stator rail 30 to the docking stator 22.

[0046] Please refer to Figure 2 as well as Figure 3 As shown, in some embodiments of the present application, the lifting module 211 includes a first support member 2111, a second support member 2112, a second power member 2114 and at least two transmission rods 2113; the first support member 2111 and the second support frame are arranged relatively to each other along the height direction of the base 10; the transmission rod 2113 is arranged along the height direction of the base 10, the transmission rod 2113 is threadedly connected to the bearing member 2121, and one end is rotatably connected to the first support member 2111, and the other end is rotatably connected to the second support member 2112; the second power member 2114 is transmission-connected to the transmission rod 2113, and can drive the transmission rod 2113 to rotate around its own axis, and the second power member 2114 is installed on the first support member 2111 or the second support member 2112.

[0047] The first support member 2111 and the second support member 2112 are arranged along the height direction of the base 10, and a space for the supporting member 2121 to move is formed between the two. After one end of the transmission rod 2113 is rotatably connected to the first support member 2111 and the other end is rotatably connected to the second support member 2112, at least two transmission rods 2113 drive the supporting member 2121 to move between the first support member 2111 and the second support member 2112 along the height direction of the base 10 when rotating in the same direction.

[0048] Please refer to Figure 2 as well as Figure 3 As shown, in some embodiments of the present application, the first support member 2111 is configured as a first support plate, the second support member 2112 is configured as a second support plate, and the second support plate is fixed to the ground. To ensure the movable range of the support member 2121, the bottom wall of the first support plate is higher than the top wall of the base 10, and the distance between the two can at least accommodate the docking stator 22 and the mover 40. For example, a stator rail 30 is fixed to the top wall of the base 10. At this time, the docking stator 22 can still be moved between the bottom wall of the support plate and the top wall of the base 10 to transfer the mover 40 from the stator rail 30 to the docking stator 22, or to transfer the mover 40 from the docking stator 22 to the stator rail 30.

[0049] The transmission rod 2113 is used to drive the supporting platform to move along the height direction of the base 10. In some embodiments of the present application, the transmission rod 2113 can be configured as a threaded rod, which is threadedly connected to the supporting platform. When multiple threaded rods rotate simultaneously in the first direction, the supporting platform moves up along the height direction of the base 10. When multiple threaded rods rotate simultaneously in the second direction, the supporting platform moves down along the height direction of the base 10. The first direction and the second direction are opposite.

[0050] Please refer to Figure 2 As shown, in the embodiment of the present application, the number of threaded rods is 4, and the 4 threaded rods are threadedly connected to the supporting platform at the four corners of the supporting platform.

[0051] It can be understood that after the support platform is connected to the threaded rod through transmission to realize the movement of the support platform in the height direction of the base 10, the maximum radial length of the rotating part 2122 must be less than the minimum distance between the multiple threaded rods. Similarly, the length of the docking stator 22 must be less than the minimum distance between the multiple threaded rods. Otherwise, the docking stator 22 will interfere with the threaded rod. At this time, in order to realize the connection between the docking stator 22 and the stator rail 30, the stator rail 30 extends to the accommodating cavity near one end of the docking assembly 20, and the support platform opens multiple avoidance openings at the ends of the multiple stator rails 30 to avoid interference between the support platform and the stator rail 30.

[0052] Please refer to Figure 2 as well as Figure 3As shown, in some embodiments of the present application, the second power member 2114 is configured as a second motor, and the lifting module 211 also includes a first transmission wheel 2115, a second transmission wheel 2116 and a transmission belt 2117. The first transmission wheel 2115 is coaxially installed on the output shaft of the second motor; the second transmission wheel 2116 is coaxially installed on the corresponding transmission rod 2113; the first transmission wheel 2115 and the second transmission wheel 2116 are connected via a transmission belt 2117.

[0053] When the second motor rotates, it drives the first transmission wheel 2115 to rotate synchronously. The first transmission wheel 2115 drives the second transmission wheel 2116 and the transmission rod 2113 to rotate synchronously via the transmission belt 2117. The rotation of the transmission rod 2113 forces the support member 2121 to move along the height direction of the base 10. Considering the four transmission rods 2113 described above, the number of second transmission wheels 2116 should also be four, and the four second transmission wheels 2116 are connected to the four transmission rods 2113 in a one-to-one correspondence.

[0054] In order to ensure that the connecting stator 22 and the stator track 30 are accurately connected, the first transmission wheel 2115 and the second transmission wheel 2116 in the embodiment of the present application can be configured as gears, and the transmission belt 2117 can be configured as a transmission chain. The transmission chain is engaged with the first transmission wheel 2115 and the second transmission wheel 2116. The ratio of the number of teeth of the first transmission wheel 2115 to the number of teeth of the second transmission wheel 2116 is less than or equal to 1 / 5. In this way, the first transmission wheel 2115 rotates multiple circles and the second transmission wheel 2116 rotates one circle, and the support platform can move more accurately in the height direction of the base 10. At the same time, the ratio of the number of teeth of the first transmission wheel 2115 to the number of teeth of the second transmission wheel 2116 is less than or equal to 1 / 5, which can also play the role of a differential.

[0055] Please refer to Figure 2 as well as Figure 3 As shown, in some embodiments of the present application, the second power member 2114 is mounted on the second support member 2112, and the lifting module 211 further includes a tensioning wheel 2118, which is rotatably mounted on the second support member 2112 and applies tension to the transmission belt 2117. The tensioning wheel 2118 ensures that the transmission belt 2117 remains taut even after prolonged use, thereby ensuring engagement between the transmission belt 2117 and the first transmission wheel 2115 and the second transmission wheel 2116, thereby ensuring that the lifting module 211 can move the docking stator 22 to an accurate position in the height direction of the base 10.

[0056] In some embodiments of the present application, there are multiple tensioning wheels 2118. At the same time, the first transmission gear can be used as a tensioning wheel 2118 to reduce the number of tensioning wheels 2118. The tensioning wheel 2118 is located on the inner side of two adjacent second transmission wheels 2116, so that the transmission belt 2117 produces a larger bend on the second transmission wheel 2116, thereby increasing the number of engagements between the transmission belt 2117 and the transmission teeth of the second transmission wheel 2116.

[0057] Please refer to Figure 2 As shown, in some embodiments of the present application, the second support member 2112 has an accommodating cavity, and the first transmission wheel 2115, the second transmission wheel 2116, the transmission belt 2117 and the tensioning wheel 2118 are all in the accommodating cavity. The first transmission wheel 2115, the second transmission wheel 2116, the transmission belt 2117 and the tensioning wheel 2118 are arranged in the accommodating cavity to protect the first transmission wheel 2115, the second transmission wheel 2116, the transmission belt 2117 and the tensioning wheel 2118.

[0058] Combined with the above-mentioned second support member 2112 fixed to the ground, the second transmission wheel 2116 is arranged at the end of the transmission rod 2113 close to the second support member 2112. At this time, the first transmission wheel 2115, the second transmission wheel 2116, the transmission belt 2117 and the tensioning wheel 2118 occupy a smaller space.

[0059] In other embodiments of the present application, the accommodating chamber may be provided on the first support member 2111 . In this case, the tensioning wheel 2118 and the second power member 2114 may both be installed on the first support member 2111 .
