Technical Field

[0003] The present application relates to the technical field of conveying devices, and in particular to a mover and a magnetic drive conveying system having the same. Background Art

[0004] Magnetic levitation technology, which enables workpiece transportation, is gaining popularity with customers due to its high conveying speed, low maintenance costs, and high flexibility. Magnetic levitation conveyor line applications often involve the diversion of a single rail or the merging of multiple rails.

[0005] In the related art, a deflection device is provided on the side of the mover to realize the reversal of the mover, which results in a complex structure and a large volume of the magnetic drive conveying system. Summary of the Invention

[0006] The purpose of this application is to provide a mover and a magnetic drive conveying system having the same, which are applied to the magnetic drive conveying system.

At this time, the mover can be reversed, so there is no need to set up an additional deflection device, thereby simplifying the structure of the magnetic drive conveying system and reducing the volume of the magnetic drive conveying system.

[0025] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0026] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0029] As shown in Figure 1, the magnetic drive conveying system 3 generally includes a mover 2 and a stator. One of the mover 2 and the stator is provided with a coil, and the other is provided with a permanent magnet. A traveling wave magnetic field is generated by exciting the coil current. The traveling wave magnetic field is magnetically coupled with the permanent magnet to realize the movement of the mover 2 relative to the stator, and a carrier is provided on the mover 2 to realize the transmission function.

[0030] In the application scenarios of the magnetic drive conveying system 3, it is often involved in the situation where a single guide rail is split or multiple guide rails are merged. In the prior art, a separate transfer mechanism is set up, such as a turntable, a transverse platform, and the like. The transfer mechanism first docks with the guide rail of the output workpiece. After the workpiece moves onto the transfer mechanism, the transfer mechanism turns or moves to dock with the guide rail of the input workpiece to transfer the workpiece from the output guide rail to the input guide rail. In this process, the transfer mechanism needs to dock with the output guide rail and the input guide rail respectively. The docking accuracy requirements are high and the docking speed is slow, which greatly affects the conveying efficiency of the conveyor line.

[0031] In some other technologies, a deflection device is provided on the side of the mover 2 to realize the reversal of the mover 2, which results in a complex structure of the magnetic drive conveying system 3, a large volume, and a large space occupation.

[0032] The mover 2 of the magnetic drive conveying system 3 of the present application is provided with a telescopic guide 7 with telescopic movement. When the telescopic guide 7 is in an extended state, it can be inserted into the slide groove of the stator of the magnetic drive conveying system 3 to fix the relative position between the mover 2 and the stator to prevent the mover 2 from separating from the stator. When the telescopic guide 7 is in a retracted state, it can be moved out of the slide groove of the stator of the magnetic drive conveying system 3. At this time, the mover 2 can be reversed, so there is no need to set up an additional deflection device, thereby simplifying the structure of the magnetic drive conveying system 3 and reducing the volume of the magnetic drive conveying system 3.

[0033] The mover 2 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0034] As shown in FIG. 2 to FIG. 6 , the mover 2 according to an embodiment of the present application is used in a magnetic drive conveying system 3 , and the mover 2 includes a base plate 10 , a first permanent magnet array 6 , a telescopic guide 7 and a first roller 900 .

[0035] The substrate 10 has a first surface 10a and a second surface 10b opposite to each other. The first surface 10a faces the stator of the magnetic drive conveying system 3, and the second surface 10b faces away from the stator of the magnetic drive conveying system 3. The first permanent magnet array 6 is provided on the first surface 10a.

[0036] The first surface 10a is used to provide a foundation for disposing the first permanent magnet array 6, and the second surface 10b is generally used to carry objects.

[0037] The stator has an armature winding, and the first permanent magnet array 6 can be a permanent magnet. When the mover 2 operates on the stator, the armature winding is energized in a periodic phase sequence, creating magnetic coupling between the first permanent magnet array 6 and the armature winding, driving the mover 2 along the stator. By changing the phase sequence of the armature winding, the direction of the driving force acting on the mover 2 can be changed, thereby changing the direction of its movement.

[0038] The first permanent magnet array 6 generates a constant magnetic field around the mover 2. By controlling the current direction and current magnitude of the armature winding, the armature winding can generate a changing traveling wave magnetic field. The changing traveling wave magnetic field interacts with the constant magnetic field of the first permanent magnet array 6 to drive the mover 2 to move; by controlling the change of the traveling wave magnetic field, the moving direction of the mover 2 is controlled, thereby realizing commutation of the mover 2.

[0039] By arranging the first permanent magnet array 6 on the first surface 10a, since the first surface 10a is closer to the stator, the driving force generated by the magnetic coupling between the first permanent magnet array 6 and the armature winding of the stator can be increased, thereby increasing the movement stability and movement speed of the mover 2.

[0040] In addition, the telescopic guide 7 can be telescopically arranged on the substrate 10, and the telescopic direction of the telescopic guide 7 is the thickness direction of the substrate 10, and the telescopic direction of the telescopic guide 7 can be perpendicular to the first surface 10a and the second surface 10b. The first surface 10a and the second surface 10b are parallel to each other. When the telescopic guide 7 is in an extended state, it extends beyond the first surface 10a. The dimension of the telescopic guide 7 extending beyond the first surface 10a when it is in an extended state is greater than the dimension of the telescopic guide 7 extending beyond the first surface 10a when it is in a retracted state.

[0041] It should be noted that when the telescopic guide 7 is in the retracted state, the telescopic guide 7 can extend beyond the first surface 10a, that is, on the basis of extending beyond the first surface 10a, the telescopic guide 7 and the stator's slide groove are released from mutual engagement, thereby being not guided by the stator's slide groove; or the telescopic guide 7 can not extend beyond the first surface 10a, so as to more stably release engagement with the stator's slide groove.

[0042] Among them, when the telescopic guide member 7 is in the extended state, it can be inserted into the stator slot to enable the mover 2 to move along the extension direction of the stator slot; when the telescopic guide member 7 is in the retracted state, it can be moved out of the stator slot, and the mover 2 can change the direction of movement.

[0043] In addition, the first roller 900 is rotatably disposed on the base plate 10 and extends beyond the first surface 10 a . The rotation axis of the first roller 900 is perpendicular to the moving direction of the mover 2 and parallel to the first surface 10 a and the second surface 10 b .

[0044] For example, the first roller 900 is located outside the slide groove of the stator, and the first roller 900 can contact the outer surface of the stator. On the one hand, during the movement of the mover 2 along the stator, the first roller 900 can provide support force for the mover 2 to ensure that the substrate 10 of the mover 2 and the stator are spaced apart from each other and the spacing is stable, and the substrate 10 of the mover 2 and the stator will not be relatively close or far away. On the other hand, it can reduce the relative friction between the mover 2 and the stator, and improve the moving speed and movement stability of the mover 2.

[0045] In some embodiments of the present application, as shown in Figures 2-6, the substrate 10 has at least one first roller 900 and at least one telescopic guide 7 on each side of its width. Specifically, the substrate 10 has one or more first rollers 900 on each side of its width, and one or more telescopic guides 7 on each side of its width. The width, thickness, and movement directions of the substrate 10 are perpendicular to each other. The substrate 10 has the same number of first rollers 900 on both sides of its width, and the same number of telescopic guides 7 on both sides of its width. The multiple first rollers 900 are positioned on both sides of the substrate 10 along the width to ensure uniform force on the mover 2, preventing deflection and ensuring stable movement. The multiple telescopic guides 7 are positioned on both sides of the substrate 10 along the width to increase the diversity of the mover 2's steering, such as allowing the telescopic guide 7 on either side to be extended or retracted depending on the operating conditions. Preferably, the first rollers 900 and telescopic guides 7 are symmetrically positioned on both sides of the substrate 10 along the width. This is to further improve the motion stability and steering stability of the mover 2.

[0046] In some embodiments of the present application, as shown in Figures 2 to 8, the substrate 10 is provided with a first mounting cavity 13 and a first opening 14. The first opening 14 is provided on the first surface 10a and is connected to the first mounting cavity 13. The telescopic guide member 7 is provided in the first mounting cavity 13 and extends beyond the first surface 10a through the first opening 14.

[0047] By providing the first mounting cavity 13, the telescopic guide member 7 can be installed within the first mounting cavity 13. When the telescopic guide member 7 is in the retracted state, the telescopic guide member 7 can be completely stored within the first mounting cavity 13. In this state, the telescopic guide member 7 does not extend beyond the first surface 10a. This reduces the probability of the telescopic guide member 7 getting stuck with the stator during reversal of the mover 2, making reversal more convenient. Furthermore, the provision of the first mounting cavity 13 improves the installation stability of the telescopic guide member 7, protecting the telescopic guide member 7 so that it can more smoothly perform its telescopic function and, to a certain extent, protect the telescopic guide member 7 from being struck by foreign objects.

[0048] By providing the first opening 14, the telescopic guide member 7 can extend beyond the first surface 10a through the first opening 14, so that the telescopic guide member 7 can be inserted into the stator slot to move the mover 2 along the extension direction of the slot, reducing the probability of the mover 2 detaching from the stator.

[0049] Furthermore, as shown in Figures 4-8 , the substrate 10 is provided with a second opening 15, which is provided on the second surface 10b. The first mounting cavity 13 includes a first cavity 13a and a second cavity 13b. The first cavity 13a is connected to the first opening 14, and the second cavity 13b is connected between the first cavity 13a and the second opening 15. The cross-sectional area of ​​the second cavity 13b as projected orthographically onto the first surface 10a is greater than the cross-sectional area of ​​the first cavity 13a as projected orthographically onto the first surface 10a.

[0050] Among them, the telescopic guide member 7 includes a mounting portion 630 and a telescopic portion 640. The telescopic portion 640 is telescopically connected to the mounting portion 630. The mounting portion 630 is located in the second cavity 13b and is connected to the inner wall of the second cavity 13b. When the telescopic guide member 7 is in an extended state, the telescopic portion 640 passes through the first cavity 13a and extends beyond the first surface 10a from the first opening 14.

[0051] Specifically, the telescopic guide member 7 can be placed in the first mounting cavity 13 through the second opening 15 until the mounting portion 630 stops at the bottom wall of the second cavity 13b, and the telescopic guide member 7 is installed in place between the substrate 10, thereby facilitating the installation of the telescopic guide member 7; by connecting the mounting portion 630 to the inner wall of the second cavity 13b, the telescopic guide member 7 can be avoided from being separated from the substrate 10, ensuring that during the movement of the mover 2, the telescopic guide member 7 can reliably cooperate with the slide groove of the stator to guide the mover 2 and prevent the mover 2 from separating from the stator.

[0052] The telescopic portion 640 is configured to extend and retract relative to the mounting portion 630, meaning that the mounting portion 630 guides the telescopic portion 640. When the telescopic portion 640 is not under force, the telescopic guide member 7 remains in an extended state, and the telescopic portion 640 is inserted into the stator's chute, allowing the mover 2 to move along the extension direction of the stator's chute. When the telescopic portion 640 is under force, the telescopic portion 640 is retracted into the first mounting cavity 13, and the telescopic guide member 7 switches to a retracted state, removing the telescopic portion 640 from the stator's chute, allowing the mover 2 to reverse direction relative to the stator and move to different directions.

[0053] 4-8 , the second cavity 13b includes a first sub-cavity 1311 and a second sub-cavity 1312. The first sub-cavity 1311 is connected to the first cavity 13a, and the second sub-cavity 1312 is connected between the first sub-cavity 1311 and the second opening 15. The cross-sectional area of ​​the second sub-cavity 1312 as projected orthographically onto the first surface 10a is greater than the cross-sectional area of ​​the first sub-cavity 1311 as projected orthographically onto the first surface 10a.

[0054] The mounting portion 630 includes a mounting seat 631 and a guide shaft 632. The telescopic portion 640 is telescopically connected to the guide shaft 632. The mounting seat 631 is located in the second sub-cavity 1312 and is connected to the bottom wall of the second sub-cavity 1312. For example, the mounting seat 631 and the bottom wall of the second sub-cavity 1312 can be connected by threaded fasteners (screws or bolts), or the mounting seat 631 and the bottom wall of the second sub-cavity 1312 can be riveted together. The guide shaft 632 is located in the first sub-cavity 1311 and abuts against the bottom wall of the first sub-cavity 1311.

[0055] In this way, when the mounting portion 630 abuts against the bottom wall of the second sub-cavity 1312, the telescopic guide 7 is installed in place between the substrate 10. By connecting the mounting seat 631 to the bottom wall of the second sub-cavity 1312, the telescopic guide 7 and the substrate 10 can be avoided from being separated, ensuring that during the movement of the mover 2, the telescopic guide 7 can reliably cooperate with the slide groove of the stator to guide the mover 2 and prevent the mover 2 from separating from the stator.

[0056] By setting up the guide shaft 632, the movement of the telescopic part 640 can be guided, and a larger displacement space is provided for the telescopic part 640 in the axial direction of the guide shaft 632. The cross-sectional area of ​​the guide shaft 632 projected onto the first surface 10a is smaller than the cross-sectional area of ​​the mounting seat 631 projected onto the first surface 10a. Therefore, while ensuring stable installation, the cost is reduced.

[0057] In some embodiments of the present application, the guide shaft 632 is a linear bearing, the inner ring surface of the linear bearing is transmission-connected to the telescopic part 640, or the guide shaft 632 includes a sleeve and a linear bearing, the outer ring surface of the linear bearing is connected to the inner ring surface of the sleeve, and the inner ring surface of the linear bearing is transmission-connected to the telescopic part 640.

[0058] In this way, the configuration of the guide shaft 632 is more diverse, which is beneficial to expanding the selection range of the guide shaft 632, so that the mover 2 has a wider range of application and is suitable for different scenarios.

[0059] By making the guide shaft 632 include a linear bearing, the balls of the linear bearing can be located on the inner circumference of the guide shaft 632 to achieve relative movement between the telescopic part 640 and the guide shaft 632, wherein the telescopic part 640 and the guide shaft 632 can move along the circumferential and axial directions of the guide shaft 632.

[0060] The telescopic portion 640 and the guide shaft 632 can move along the axial direction of the guide shaft 632, so that the telescopic guide member 7 can be switched between the extended state and the retracted state to achieve reversal of the mover 2.

[0061] When the telescopic part 640 is inserted into the slide groove of the stator, friction may be generated between the telescopic part 640 and the groove wall of the slide groove. The telescopic part 640 and the guide shaft 632 can rotate along the circumferential direction of the guide shaft 632, which can reduce the friction between the telescopic part 640 and the groove wall of the slide groove and improve the service life of the telescopic guide 7, thereby increasing the movement speed of the mover 2 and making the mover 2 move more smoothly.

[0062] When the guide shaft 632 is a linear bearing, the linear bearing is fixedly connected to the mounting seat 631. For example, the linear bearing and the mounting seat 631 can be formed into an integrated structure, which is easy to process and has high structural strength; or, the linear bearing is interference fit with the first sub-cavity 1311, and the linear bearing is interference fit with the first sub-cavity 1311. At this time, the linear bearing and the mounting seat 631 can be separately set. In this way, when one of the linear bearing and the mounting seat 631 is damaged, there is no need to replace the other together, thereby reducing maintenance costs; or, the linear bearing is clamped by the mounting seat 631 and the bottom wall of the first sub-cavity 1311, and the linear bearing is clamped by the mounting seat 631 and the bottom wall of the first sub-cavity 1311, that is, the mounting seat 631 and the bottom wall of the first sub-cavity 1311 apply clamping force to the linear bearing from both ends of the axial direction of the linear bearing to fix the position of the linear bearing. In this way, after the mounting seat 631 is disassembled, the disassembly of the linear bearing is also relatively convenient, which improves the convenience of disassembly and assembly of the mover 2 and facilitates later maintenance.

[0063] When the guide shaft 632 includes a sleeve and a linear bearing, the linear bearing and the sleeve are interference fit to fix the relative position between the linear bearing and the sleeve.

[0064] Among them, the shaft sleeve can be fixedly connected to the mounting seat 631, for example, the shaft sleeve and the mounting seat 631 can be formed into an integrated structure, which is easy to process and has high structural strength; or the shaft sleeve has an interference fit with the first sub-cavity 1311, at this time the shaft sleeve and the mounting seat 631 can be separately set, so that when one of the shaft sleeve and the mounting seat 631 is damaged, there is no need to replace the other together, thereby reducing maintenance costs; or, the shaft sleeve is clamped by the mounting seat 631 and the bottom wall of the first sub-cavity 1311, that is, the mounting seat 631 and the bottom wall of the first sub-cavity 1311 apply clamping force to the shaft sleeve from both axial ends of the shaft sleeve to fix the position of the shaft sleeve, so that after the mounting seat 631 is disassembled, the shaft sleeve is also more convenient to disassemble, which improves the convenience of disassembly and assembly of the mover 2 and facilitates later maintenance.

[0065] In some embodiments of the present application, as shown in Figures 5, 6 and 9, the telescopic portion 640 includes a limiting section 641 and a guide section 642. The limiting section 641 is inserted into the guide shaft 632. The limiting section 641 stops at the bottom wall of the second cavity 13b. The guide section 642 is connected to the limiting section 641. When the telescopic guide member 7 is in the extended state, the guide section 642 extends beyond the first surface 10a from the first opening 14.

[0066] For example, the outer contour of the cross section of the limiting section 641 is circular, and the outer contour of the cross section of the guide section 642 is circular. In this way, the installation of the telescopic portion 640 is more convenient, and the telescopic portion 640 and the guide shaft 632 do not need to be installed at a characteristic angle.

[0067] By dividing the telescopic part 640 into a limiting section 641 and a guiding section 642, the limiting section 641 can abut against the bottom wall of the second cavity 13b, limiting the maximum displacement stroke between the telescopic part 640 and the guide shaft 632 and the substrate 10, thereby preventing the telescopic part 640 from separating from the guide shaft 632 and the substrate 10, and the guiding section 642 can move freely in the first opening 14, so as to facilitate the telescopic part 640 to extend out of the first surface 10a and insert into the stator's slide groove, thereby realizing the stator's guidance of the movement of the mover 2, and the telescopic part 640 can be moved out of the stator's slide groove to realize the turning of the mover 2.

[0068] The limiting section 641 includes a linear bearing, the outer ring surface of the linear bearing contacts the inner ring surface of the guide shaft 632, and the limiting section 641 is slidable relative to the guide shaft 632. The limiting section 641 can be entirely a linear bearing, or the limiting section 641 can be partially a linear bearing.

[0069] By making at least a portion of the limiting section 641 a linear bearing, the balls of the linear bearing can be located on the outer ring surface of the limiting section 641 to achieve relative movement between the limiting section 641 and the guide shaft 632, wherein the limiting section 641 and the guide shaft 632 can move along the circumferential and axial directions of the guide shaft 632.

[0070] The limiting section 641 and the guide shaft 632 can move along the axial direction of the guide shaft 632, so that the telescopic guide member 7 can be switched between the extended state and the retracted state, so as to realize the reversal of the mover 2 on the track conversion stator 1.

[0071] When the telescopic part 640 is inserted into the slide groove of the stator, friction may be generated between the telescopic part 640 and the groove wall of the slide groove. The limiting section 641 and the guide shaft 632 can rotate along the circumferential direction of the guide shaft 632, which can reduce the friction between the telescopic part 640 and the groove wall of the slide groove and increase the service life of the telescopic guide 7, thereby increasing the movement speed of the mover 2 and making the mover 2 move more smoothly.

[0072] Furthermore, the telescopic guide member 7 includes an elastic member (not shown). The elastic member can be a spring or other elastically deformable component. The elastic member is located within the guide shaft 632. One end of the elastic member abuts against the stopper 641, while the other end abuts against the guide shaft 632 or the mounting seat 631. When compressed, the elastic member exerts a force that drives the telescopic portion 640 beyond the first surface 10a.

[0073] For example, the inner wall of the guide shaft 632 is provided with a stop step (not shown in the figure), one end of the elastic member stops at the limiting section 641, and the other end of the elastic member stops at the stop step of the guide shaft 632; or, one end of the elastic member stops at the limiting section 641, and the other end of the elastic member stops at the mounting seat 631.

[0074] When the telescopic guide member 7 is in the extended state, that is, when the limit section 641 stops at the bottom wall of the second cavity 13b, the elastic member is also in a compressed state (that is, the length of the elastic member is still smaller than the length of the elastic member in the natural state at this time), and the elastic member applies an elastic force to the telescopic portion 640. Therefore, when the telescopic portion 640 is not subjected to external force, the telescopic guide member 7 can be stably maintained in the extended state to prevent the mover 2 from separating from the stator.

[0075] By setting an elastic member, the telescopic guide member 7 can be kept in the extended state when the mover 2 is not subjected to external force, ensuring that the telescopic guide member 7 is in the extended state in a natural state, thereby avoiding the accidental contraction of the telescopic part 640, and when the telescopic guide member 7 is in the contracted state due to external force on the mover 2, when the external force disappears, the elastic force immediately pushes the telescopic guide member 7 to return to the extended state. In this way, except during the reversing process of the mover 2, the telescopic part 640 can be reliably inserted into the slide groove of the stator, reducing the probability of the mover 2 detaching from the stator and improving the stability of the movement of the mover 2.

[0076] Furthermore, as shown in Figures 5-6 and 9, the end surface of the mounting seat 631 facing the guide shaft 632 is provided with a first positioning structure 633, and the end surface of the limiting section 641 facing the mounting seat 631 is provided with a second positioning structure 643, and one end of the elastic member is connected to the first positioning structure 633 and the other end is connected to the second positioning structure 643.

[0077] By setting the first positioning structure 633, the relative position between the mounting seat 631 and the elastic member can be fixed. By setting the second positioning structure 643, the relative position between the limiting section 641 and the elastic member can be fixed, that is, the relative position between the telescopic part 640 and the elastic member can be fixed. The inner wall of the guide shaft 632 can limit the deflection stroke of the elastic member, thereby ensuring that the deformation, deflection and displacement of the elastic member will not exceed expectations, so that the force exerted by the elastic member on the telescopic part 640 is in line with expectations, ensuring that the telescopic member can be effectively and quickly reset.

[0078] Furthermore, as shown in Figures 5-6 and 9, the first positioning structure 633 is at least one of a positioning slot and a positioning post. That is, the first positioning structure 633 can be a positioning slot, in which case the end of the elastic member is inserted into the positioning slot, and the groove wall of the positioning slot limits the end of the elastic member; or the first positioning structure 633 can be a positioning post, in which case the end of the elastic member is sleeved on the positioning post, and the positioning post limits the end of the elastic member; or the first positioning structure 633 can include a positioning post and a positioning slot, with the positioning post provided at the bottom of the positioning slot, in which case the end of the elastic member is inserted into the positioning slot and sleeved on the positioning post, and the groove wall of the positioning slot and the positioning post jointly limit the end of the elastic member.

[0079] In this way, the position of the end of the elastic member facing the first positioning structure 633 in the mover 2 can be fixed, avoiding the end of the elastic member facing the first positioning structure 633 from being offset, and ensuring the reliability of the elastic member in resetting the telescopic guide member 7.

[0080] The second positioning structure 643 is at least one of a positioning slot and a positioning post. That is, the second positioning structure 643 can be a positioning slot, in which case the end of the elastic member is inserted into the positioning slot, and the groove wall of the positioning slot limits the end of the elastic member; or the second positioning structure 643 can be a positioning post, in which case the end of the elastic member is sleeved on the positioning post, and the positioning post limits the end of the elastic member; or the second positioning structure 643 can include a positioning post and a positioning slot, with the positioning post provided at the bottom of the positioning slot, in which case the end of the elastic member is inserted into the positioning slot and sleeved on the positioning post, and the groove wall and the positioning post jointly limit the end of the elastic member.

[0081] In this way, the position of the end of the elastic member facing the second positioning structure 643 in the mover 2 can be fixed, avoiding the end of the elastic member facing the second positioning structure 643 from being offset, and ensuring the reliability of the elastic member in resetting the telescopic guide member 7.

[0082] In some embodiments of the present application, as shown in Figures 2-4, the substrate 10 is provided with a second mounting cavity 16 and a third opening 17, the third opening 17 is provided on the first surface 10a and is connected to the second mounting cavity 16, and the first roller 900 is provided in the second mounting cavity 16 and extends beyond the first surface 10a through the third opening 17.

[0083] By providing the second mounting cavity 16 , on the one hand, the weight of the substrate 10 can be reduced, and on the other hand, it can be used to accommodate a portion of the first roller 900 , thereby reducing the overall size of the first roller 900 and the substrate 10 in the thickness direction of the substrate 10 , which is beneficial to the lightweight setting of the mover 2 .

[0084] For example, the substrate 10 may be provided with a fourth opening 18 on the second surface 10b, and the fourth opening 18 is connected to the second mounting cavity 16. The first roller 900 may also extend beyond the second surface 10b through the fourth opening 18. The volume of the second mounting cavity 16 is larger and can accommodate more first rollers 900. The size of the first roller 900 in the thickness direction of the substrate 10 can be increased accordingly. On the one hand, the space utilization of the substrate 10 is improved. On the other hand, the mover 2 can install more first rollers 900 of different sizes, expanding the selection range of the first roller 900 to adapt to different usage scenarios.

[0085] Of course, those skilled in the art will understand that the substrate 10 may not have the fourth opening 18 on the second surface 10b, that is, the second mounting cavity 16 is closed on the side facing the second surface 10b, the second surface 10b of the substrate 10 is neater, and the structural strength of the substrate 10 is high.

[0086] In some embodiments of the present application, as shown in Figures 2 to 4, at least one of the first surface 10a and the second surface 10b is provided with a weight-reducing groove 19. This can reduce the weight of the mover 2 and thus the production cost of the mover 2. Furthermore, due to the reduced weight of the mover 2, the mover 2 has less inertia, and the mover 2 needs to overcome less inertial force during reversing. Therefore, the mover 2 can achieve reversing under the action of a smaller driving force, thereby improving the reversing speed and smoothness, and making reversing of the mover 2 more convenient.

[0087] In some embodiments of the present application, as shown in Figures 2-4 and 10-12, the substrate 10 has a third surface 10c, which is connected between the first surface 10a and the second surface 10b. The third surface 10c is provided with a second permanent magnet array (not shown in the figures). The third surface 10c is parallel to the extension direction of the substrate 10.

[0088] Specifically, an electromagnetic reversing drive is provided on the track switching stator 1, and is disposed adjacent to the confluence end 101. The electromagnetic reversing drive is magnetically coupled to the second permanent magnet array, acting on the mover 2 without contacting the mover 2. By changing the direction of the current flowing through the electromagnetic reversing drive, a magnetic attraction or repulsion is generated between the electromagnetic reversing drive and the second permanent magnet array, thereby guiding the mover 2 from the confluence end 101 to the first conveying track 200, or guiding the mover 2 from the confluence end 101 to the second conveying track 300.

[0089] It can be seen from this that the second permanent magnet array can assist in adjusting the moving direction of the mover 2, and since the second permanent magnet array is located on the third surface 10c of the mover 2, the distance between the third surface 10c and the first permanent magnet array 6 is relatively far, so the magnetic field of the second permanent magnet array has little effect on the first permanent magnet array 6, and thus has little effect on the magnetic coupling between the first permanent magnet array 6 of the mover 2 and the first armature winding 210 and the second armature winding 310, thereby ensuring the smooth movement of the mover 2 along the first conveying track 200 and the second conveying track 300.

[0090] In some embodiments of the present application, the mover 2 further includes a second roller (not shown in the figure), which is rotatably provided on the base plate 10, and the rotation axis of the second roller is perpendicular to the first surface 10a and the second surface 10b.

[0091] For example, the substrate 10 has a third surface 10c connected between the first surface 10a and the second surface 10b. The third surface 10c is parallel to the extension direction of the substrate 10. The second roller can be installed on the third surface 10c and extend beyond the third surface 10c.

[0092] Specifically, there may be multiple second rollers, and the multiple second rollers may be disposed on opposite sides of the base plate 10. When the mover 2 is located in the track conversion stator 1, at least one second roller is located in the first chute 411 and contacts the groove wall of the first chute 411. At least one second roller is located in the second chute 421 and contacts the groove wall of the second chute 421. When the mover 2 is located in the remaining stators of the magnetic drive conveying system 3, the second rollers are also located in the chute of the corresponding stator and contact the groove wall of the chute.

[0093] By setting a second roller, the displacement space of the mover 2 in the width direction of the slide groove can be reduced without affecting the smoothness of the movement of the mover 2 relative to the stator, which is beneficial to improving the position stability of the mover 2 and the stator in the width direction of the stator. The mover 2 is less likely to have problems such as eccentricity and uneven force, and the movement is smoother.

[0094] In some embodiments of the present application, as shown in FIG2 , the extension of the telescopic guide member 7 beyond the first surface 10a when in the extended state is greater than the extension of the first roller 900 beyond the first surface 10a. Thus, when the telescopic guide member 7 is in the extended state, the first roller 900 can contact the outer surface of the stator, and the telescopic guide member 7 can be inserted into the stator's chute, facilitating the mating of the mover 2 and the stator.

[0095] In a second aspect, as shown in FIG1 , an embodiment of the present application provides a magnetic drive conveying system 3, comprising a mover 2 and a stator as described above, wherein the stator comprises a track, and the track comprises an armature winding. When energized, the armature winding is magnetically coupled with a first permanent magnet array 6 to drive the mover 2 to move along the track. The stator may comprise an arc-shaped stator or a linear stator.

[0096] The magnetic drive conveying system 3 described in the embodiment of the present application, by applying the mover 2 in the magnetic drive conveying system 3, can not only realize the diversion of a single guide rail or the merging of multiple guide rails, but also does not require a separate deflection mechanism, thereby simplifying the structure of the magnetic drive conveying system 3 and reducing the volume.

[0097] Further, as shown in Figures 10-12, the stator includes a track conversion stator 1, the track conversion stator 1 has a converging end 101, a first branch end 102 and a second branch end 103, the track conversion stator 1 includes a first conveying track 200 and a second conveying track 300, the first conveying track 200 is located between the converging end 101 and the first branch end 102, the first conveying track 200 includes a first armature winding 210, the first armature winding 210 is used to drive the mover 2 of the magnetic drive conveying system 3 to move between the converging end 101 and the first branch end 102, the second conveying track 300 is located between the converging end 101 and the second branch end 103, the second conveying track 300 includes a second armature winding 310, the second armature winding 310 is used to drive the mover 2 to move between the converging end 101 and the second branch end 103.

[0098] By setting the track conversion stator 1, the mover 2 can be diverted from the merging end 101 to the first shunt end 102 and the second shunt end 103, or the mover 2 can be merged from the first shunt end 102 and the second shunt end 103 to the merging end 101, thereby realizing the reversal of the mover 2.

[0099] Furthermore, as shown in FIG2 , there are multiple telescopic guide members 7 , at least one of which is a first telescopic guide member 610 and at least another of which is a second telescopic guide member 620 . The first telescopic guide member 610 is provided on one side of the width direction of the mover 2, and the second telescopic guide member 620 is provided on the other side of the width direction of the mover 2. It should be noted that the width direction of the mover 2 is perpendicular to the thickness direction of the mover 2 and the direction of movement of the mover 2. Furthermore, there can be one or more first telescopic guide members 610. When there are multiple first telescopic guide members 610, the multiple first telescopic guide members 610 are arranged at intervals along the direction of movement of the mover 2. There can be one or more second telescopic guide members 620. When there are multiple second telescopic guide members 620, the multiple second telescopic guide members 620 are arranged at intervals along the direction of movement of the mover 2. The number and positions of the multiple first telescopic guide members 610 and the multiple second telescopic guide members 620 can be set in a one-to-one correspondence.

[0100] As shown in FIG. 10 to FIG. 12 , the track switching stator 1 further includes a commutation structure, and the commutation structure includes a first guide member 410 and a second guide member 420 .

[0101] The first guide member 410 defines a first slide groove 411, or the first guide member 410 and the first conveying track 200 jointly define the first slide groove 411. When the mover 2 moves along the first conveying track 200, the first telescopic guide member 610 is slidably disposed in the first slide groove 411, and a first telescopic member 430 with telescopic movement is disposed in the first slide groove 411.

[0102] For example, the first guide member 410 includes a first shoulder 412 , which together with the first conveying track 200 defines a first slide groove 411 , or the first guide member 410 includes a first shoulder 412 and a first shoulder 413 , which together define a first slide groove 411 .

[0103] The second guide member 420 defines a second slide groove 421, or the second guide member 420 and the second conveying track 300 jointly define the second slide groove 421. When the mover 2 moves along the second conveying track 300, the second telescopic guide member 620 can be slidably disposed in the second slide groove 421, and a second telescopic member 440 with telescopic movement is provided in the second slide groove 421.

[0104] For example, the second guide member 420 includes a second shoulder 422 , which together with the second conveying track 300 defines a second slide groove 421 , or the second guide member 420 includes a second shoulder 422 and a second shoulder 423 , which together define a second slide groove 421 .

[0105] By setting a first slide groove 411, which cooperates with the first telescopic guide 610 of the mover 2, when the mover 2 moves along the first conveying track 200, the first slide groove 411 can limit and guide the mover 2 through the first telescopic guide 610; by setting a second slide groove 421, which cooperates with the second telescopic guide 620 of the mover 2, when the mover 2 moves along the second conveying track 300, the second slide groove 421 can limit and guide the mover 2 through the second telescopic guide 620.

[0106] It should be noted that, in this embodiment, the first telescopic member 430 is telescopically arranged along the depth direction of the first slide groove 411. Therefore, when the first telescopic member 430 is in the retracted state, the first telescopic member 430 sinks to allow the first telescopic guide member 610 to be inserted into the first slide groove 411. When the first telescopic member 430 is in the extended state, the first telescopic member 430 is lifted to allow the first telescopic guide member 610 to be separated from the first slide groove 411. The second telescopic member 440 is telescopically arranged along the depth direction of the second slide groove 421. Therefore, when the second telescopic member 440 is in the retracted state, the second telescopic member 440 sinks. So that the second telescopic guide member 620 is inserted into the second slide groove 421, and when the second telescopic member 440 is in the extended state, the second telescopic member 440 is lifted to disengage the second telescopic guide member 620 from the second slide groove 421; the third telescopic member 731 is telescopically arranged along the depth direction of the third slide groove 730, so that when the third telescopic member 731 is in the retracted state, the third telescopic member 731 sinks to allow the second telescopic guide member 620 to be inserted into the third slide groove 730, and when the third telescopic member 731 is in the extended state, the third telescopic member 731 is lifted to allow the second telescopic guide member 620 to disengage from the third slide groove 730.

[0107] When the mover 2 moves between the confluence end 101 and the first divergence end 102 , the first telescopic member 430 sinks, the first telescopic guide member 610 is in an extended state and inserted into the first slide groove 411 , and the second telescopic member 440 is lifted, so that the second telescopic guide member 620 is in a retracted state.

[0108] In this way, the second telescopic guide member 620 can be led out of the second slide groove 421. Since the second telescopic guide member 620 is led out of the second slide groove 421, the first telescopic guide member 610 still remains in the first slide groove 411. Therefore, the mover 2 can be limited and guided by the first slide groove 411 at this time, so that the mover 2 moves along the first conveying track 200.

[0109] When the mover 2 moves between the confluence end 101 and the second divergence end 103 , the second telescopic member 440 sinks, the second telescopic guide member 620 is in an extended state and inserted into the second slide groove 421 , and the first telescopic member 430 is lifted, so that the first telescopic guide member 610 is in a retracted state.

[0110] In this way, the first telescopic guide member 610 can be led out of the first slide groove 411. Since the first telescopic guide member 610 is led out of the first slide groove 411, the second telescopic guide member 620 is still maintained in the second slide groove 421. Therefore, the mover 2 can be limited and guided by the second slide groove 421 at this time, so that the mover 2 moves along the second conveying track 300.

[0111] By cooperating with each other, the first telescopic member 430, the second telescopic member 440, the first slide groove 411 and the second slide groove 421 can assist in adjusting the moving direction of the mover 2. Compared with applying force to the mover 2 in a non-contact manner, the first telescopic member 430 and the second telescopic member 440 both apply force to the mover 2 in a contact manner. The force applied to the mover 2 is continuous, stable and precise, the movement reliability of the mover 2 is higher and the switching speed is faster.

[0112] In some embodiments of the present application, the track conversion stator 1 further comprises a third shunt end 104. The track conversion stator 1 further comprises a third conveying track 700, which is disposed on the base 100 and is located between the converging end 101 and the third shunt end 104. The third conveying track 700 comprises a third armature winding 710, which is used to drive the mover 2 to move between the converging end 101 and the third shunt end 104.

[0113] In this way, the mover 2 can be diverted from the confluence end 101 to any one of the first diversion end 102, the second diversion end 103 and the third diversion end 104 through the track conversion stator 1, and can be merged from the first diversion end 102, the second diversion end 103 and the third diversion end 104 to the confluence end 101. The track conversion stator 1 can drive the mover 2 in more conveying directions, which is conducive to the application of the track conversion stator 1 to a more complex magnetic drive conveying system 3.

[0114] The above-mentioned reversing structure includes a third guide member 720, the third guide member 720 defines a third slide groove 730, or the third guide member 720 and the third conveying track 700 jointly define the third slide groove 730, the third slide groove 730 is connected to the second slide groove 421, and a third telescopic member 731 with telescopic movement is provided in the third slide groove 730. When the third telescopic member 731 is lifted, it acts on the mover 2 by contacting the mover 2 to guide the mover 2 to move from the confluence end 101 to the first conveying track 200 or the second conveying track 300.

[0115] For example, the third guide member 720 includes a third shoulder 721 , which together with the third conveying track 700 defines a third slide groove 730 , or the third guide member 720 includes a third shoulder 721 and a third shoulder 722 , which together with the second shoulder 423 defines a third slide groove 730 .

[0116] The following describes, with reference to the accompanying drawings, an example of the commutation method of the mover 2 on the track switching stator 1 when the track switching stator 1 has the third shunt end 104:

[0117] As shown in Figure 11, when the mover 2 is located at the confluence end 101, if the mover 2 moves toward the first diversion end 102, the first telescopic member 430 is in a retracted state, and the first telescopic member 430 and the first telescopic guide member 610 may not contact each other, so that the first telescopic guide member 610 remains in the first slide groove 411. The first slide groove 411 guides and limits the first telescopic guide member 610, so that the mover 2 can move along the first conveying track 200 to the first diversion end 102, and the second telescopic member 440 and the third telescopic member 731 are in an extended state, the second telescopic member 440 contacts the second telescopic guide 620, and the first telescopic member 430 contacts the second telescopic guide 620. The second telescopic guide member 620 applies a force to cause the second telescopic guide member 620 to retract and be located outside the second slide groove 421. The second telescopic guide member 620 is free from the restriction of the second slide groove 421. The second slide groove 421 does not guide the second telescopic guide member 620. As a result, the movement trajectory of the mover 2 is not restricted by the second slide groove 421. At the same time, the third telescopic member 731 extends to apply a force to the second telescopic guide member 620, so that the second telescopic guide member 620 remains retracted and located outside the third slide groove 730, thereby preventing the second telescopic guide member 620 from being stuck in the third slide groove 730, thereby ensuring the smooth movement of the mover 2.

[0118] As shown in Figure 11, when the mover 2 is located at the confluence end 101, if the mover 2 moves toward the second diversion end 103, the second telescopic member 440 is in a retracted state, and the second telescopic member 440 and the second telescopic guide member 620 may not contact each other, so that the second telescopic guide member 620 remains in the second chute 421, and the second chute 421 guides and limits the second telescopic guide member 620, so that the mover 2 can move along the second conveying track 300 to the second diversion end 103, and the first telescopic member 430 and the third telescopic member 731 are in an extended state, and the first telescopic member 430 contacts the first telescopic guide 610, The first telescopic guide member 610 applies a force to retract the first telescopic guide member 610 and locate it outside the first slide groove 411. The first telescopic guide member 610 is free from the restriction of the first slide groove 411. The first slide groove 411 does not guide the first telescopic guide member 610. As a result, the movement trajectory of the mover 2 is not restricted by the first slide groove 411. At the same time, the third telescopic member 731 extends to apply a force to the second telescopic guide member 620, so that the second telescopic guide member 620 remains retracted and located outside the third slide groove 730, thereby preventing the second telescopic guide member 620 from being stuck in the third slide groove 730, thereby ensuring the smooth movement of the mover 2.

[0119] As shown in Figure 11, when the mover 2 is located at the confluence end 101, if the mover 2 moves toward the third diversion end 104, the second telescopic member 440 and the third telescopic member 731 are in a retracted state, and the second telescopic member 440 and the second telescopic guide member 620 and the third telescopic member 731 and the second telescopic guide member 620 may not contact each other, so that the second telescopic guide member 620 can slide along the second slide groove 421 into the third slide groove 730, and the second slide groove 421 and the third slide groove 730 guide and limit the second telescopic guide member 620, thereby moving The mover 2 can move along the third conveying track 700 to the third diversion end 104, and the first telescopic member 430 is in an extended state. The first telescopic member 430 contacts the first telescopic guide member 610 and applies a force to the first telescopic guide member 610 to cause the first telescopic guide member 610 to shrink and be located outside the first slide groove 411. The first telescopic guide member 610 is free from the restriction of the first slide groove 411, and the first slide groove 411 does not guide the first telescopic guide member 610, so that the movement trajectory of the mover 2 is not restricted by the first slide groove 411 at this time.
