[0036] The following describes embodiments of the present invention in detail. 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0038] In the description of this utility model, "several" means more than one, "plurality" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of the terms "first" and "second" is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0041] Logistics conveyor lines are widely used in various fields such as express sorting, warehousing and transportation, production and manufacturing. They use magnetic levitation technology to transport workpieces. They have the characteristics of fast transportation speed, low maintenance cost and high flexibility, and are favored by more and more customers.

[0042] In the prior art, in order to ensure the operation accuracy, mutually cooperating guide structures are often provided on the magnetic driver and the frame. For example, a conveying slide is provided on the frame, and correspondingly, a slide adapted to the conveying slide is provided on the magnetic driver. The slide of the magnetic driver is engaged with the linear slide to realize the movement and guidance of the magnetic driver. However, the volume of the conveying module with the additional guide structure is often large, and the volume of the magnetic driver is also large, resulting in a large gap between adjacent magnetic drivers. The number of magnetic drivers that can run simultaneously in the magnetic drive conveying system is small, and the conveying efficiency is limited.

[0043] To solve the above problems, the first embodiment of the present application proposes a magnetic drive conveying system, which includes a conveying module 100 and a plurality of magnetic drivers 200. The magnetic drivers 200 can carry the workpiece and move on the conveying module 100 to convey the workpiece to a set location. Figures 1 to 3As shown, the conveying module 100 includes a frame 110 and two support members 120. A driving member 111 is laid on the frame 110, and the two support members 120 are respectively located on both sides of the driving member 111. It should be noted that the support member 120 and the driving member 111 do not need to be set at the same height position. Figure 1 In the illustrated embodiment, the driver 111 is disposed below the top plate of the frame 110, and the support members 120 are fixedly connected to the side plates of the frame 110. The two support members 120 define a guide channel 130, and the magnetic driver 200 is at least partially located in the guide channel 130. Furthermore, the side walls of the magnetic driver 200 abut against the side walls of the guide channel 130. When the magnetic driver 200 is driven to move, it is limited by the support members 120 on both sides and can move along a set path. In other words, the support members 120 serve as a guide for the movement of the magnetic driver 200.

[0044] And, as Figure 3 As shown, the magnetic driver 200 abuts against the support member 120 so that a certain distance is maintained between the magnetic driver 200 and the driver 111, so as to reduce the friction resistance of the magnetic driver 200 and improve the electromagnetic coupling efficiency of the magnetic driver 200 and the driver 111.

[0045] Based on the above, it can be found that the support member 120 of the present application plays the role of support and guidance at the same time, so there is no need to set up a guide structure of a slide rail or a slide groove, which greatly reduces the volume of the magnetic driver 200 and the conveying module 100, thereby enabling the miniaturization of the magnetic drive conveying system.

[0046] In addition, the driving member 111 includes multiple coil windings, multiple power supplies, and multiple controllers (not shown in the figure), that is, each coil winding is configured to be connected to a separate power supply and controller, which can independently adjust the amplitude and phase of the current of the coil winding, so that when the magnetic driver 200 passes through each coil winding, each coil winding can be activated in turn to form a synthetic magnetic field. By precisely controlling the current of each phase winding, a traveling wave magnetic field with a sinusoidal distribution along the direction of movement can be formed. This traveling wave magnetic field is electromagnetically coupled with the magnetic field of the magnet 240 on the magnetic driver 200 to generate thrust to drive the magnetic driver 200 to move. A phase difference of 90 degrees (π / 2) is maintained between the traveling wave magnetic field and the magnetic field of the magnetic driver 200 to generate maximum thrust.

[0047] In the prior art, the magnetic drive conveying system uses a three-phase permanent magnet synchronous motor to drive the magnetic driver. The motor has three-phase windings u, v, and w, and the three-phase currents in u, v, and w are spaced 120 degrees apart from each other. That is to say, when there is current in the u-phase motor, there must also be currents in the v-phase and w-phase that are spaced 120 degrees apart from each other. Therefore, when the magnet of the magnetic driver is in the u-phase winding position, the u-phase winding needs to provide a current of the corresponding waveform to generate a traveling wave magnetic field. At the same time, the v-phase and w-phase windings also consume current to generate an invalid traveling wave magnetic field. In addition, since the three-phase permanent magnet synchronous motor needs to be spaced at least 3 to 4 coils apart, the gap between adjacent magnetic drivers on the conveyor line will be large, which is not suitable for application scenarios with dense movers or small movers.

[0048] In the present application, on the one hand, by optimizing the guide structure, the support and guide functions are achieved through the support member 120, replacing the slide rail structure in the prior art, and reducing the specifications of the magnetic driver 200. In addition, by optimizing the drive structure, each coil winding is individually configured with a power supply and a controller so that the current of each coil winding can be adjusted individually, thereby reducing the gap between adjacent magnetic drivers 200, so that more magnetic drivers 200 can be allowed to operate on the conveyor line of the same specification. This miniaturized, high-density magnetic drive conveying system is suitable for small load and large-volume working conditions, and can complete the conveying work at high speed and high efficiency.

[0049] In some embodiments, the support member 120 includes an extension portion 121 and an abutting portion 122. The two ends of the extension portion 121 are connected to the frame 110 and the abutting portion 122 respectively, and the abutting portions 122 of the two support members 120 extend toward each other. Figure 2 and Figure 3 In the illustrated embodiment, the extensions 121 of the two support members 120 extend vertically and are arranged side by side. The abutment portions 122 of the two support members 120 extend horizontally toward each other, so that the distance between the two abutment portions 122 is smaller than the distance between the two extensions 121. For convenience of subsequent description, the space between the two abutment portions 122 is defined as a first guide groove 131, and the space between the two extensions 121 is defined as a second guide groove 132. It will be understood that the first guide groove 131 and the second guide groove 132 are both part of the guide channel 130.

[0050] like Figure 2 and Figure 3As shown, the magnetic driver 200 is arranged in the first guide groove 131 and the second guide groove 132. Specifically, the magnetic driver 200 includes a first main body 210, a second main body 220, a connecting portion 230 and a magnet 240. The first main body 210 is located outside the guide channel 130 and is exposed to the frame 110 for carrying the workpiece. The second main body 220 is located in the second guide groove 132. A magnet 240 is provided on the wall of the second main body 220 opposite to the frame 110. The magnet 240 is generally a permanent magnet and can be electromagnetically coupled with the driving member 111 to be driven to move the magnetic driver 200. The first main body 210 and the second main body 220 are connected by the connecting portion 230, which is arranged in the first guide groove 131.

[0051] It is understandable that the conveying module 100 can be used upright or inverted. Figure 1 Taking the upright posture shown as an example, the magnetic driver 200 is arranged above the frame 110, and the workpiece can be placed directly on the top surface of the first main body 210. The bottom surface of the first main body 210 abuts against the top surface of the abutment portion 122 (the surface of the abutment portion 122 facing away from the frame 110), so that the magnetic driver 200 is mounted on the frame 110, and a certain gap is maintained between the bottom surface of the magnet 240 and the driving member 111.

[0052] In other embodiments (not shown in the figures), the conveying module 100 is arranged in an inverted posture, that is, the magnetic driver 200 is arranged below the frame 110, and the workpiece can be connected to the first main body 210 by hanging or the like, and the bottom surface of the second main body 220 abuts against the top surface of the abutting portion 122 (the surface of the abutting portion 122 facing the frame 110) to hang the magnetic driver 200 on the frame 110, and a certain gap is maintained between the top surface of the magnet 240 and the driving member 111.

[0053] Based on the above, when the conveying module 100 is upright, the first main body 210 abuts against the abutting portion 122, and the bottom surface of the first main body 210 is provided with a friction portion, so that the first main body 210 abuts against the abutting portion 122 through the friction portion. The friction portion is made of a wear-resistant material with a low friction coefficient, which can reduce sliding friction while having a long service life. It should be noted that the friction portion can be a coating applied to the bottom surface of the first main body 210, or the friction portion can be a sticker attached to the bottom surface of the first main body 210, or the friction portion can be an insert embedded in the bottom groove of the first main body 210, or the entire first main body 210 can be made of a wear-resistant material.

[0054] Similarly, when the conveying module 100 is inverted, the second main body 220 abuts against the abutment portion 122, so that a friction portion is provided on the bottom surface of the second main body 220, and the second main body 220 abuts against the abutment portion 122 through the friction portion, or the second main body 220 is made of wear-resistant material.

[0055] It should be noted that the support member 120 can not only support the magnetic driver 200 but also guide it. Figure 3 As shown, the side walls of the second main body 220 respectively abut against the groove walls of the second guide groove 132, thereby guiding the movement of the magnetic driver 200. Alternatively, the two sides of the connecting portion 230 respectively abut against the groove walls of the first guide groove 131 to guide the movement of the magnetic driver 200. Alternatively, both sides of the connecting portion 230 and both sides of the second main body 220 play a guiding role. Thus, when the magnetic driver 200 is driven to move, the support member 120 can guide its movement.

[0056] In some embodiments, the magnetic drive conveying system can achieve point-to-point conveying from one loading station to one unloading station. In other embodiments, the magnetic drive conveying system needs to achieve workpiece conveying from multiple loading stations to one unloading station, from one loading station to multiple unloading stations, or from multiple loading stations to multiple unloading stations. This involves the bifurcation and merging of conveying routes. When facing a bifurcation, the magnetic drive 200 must be stably and reliably guided into the correct path.

[0057] To this end, the magnetic drive conveying system further includes a branch module 300, such as Figures 4 to 7 As shown, a branch module 300 is docked with at least three conveying modules 100. The branch module 300 is provided with a plurality of diverter channels and a converging channel 330, each of which is connected to the guide channel 130 of a different conveying module 100. The branch module 300 also includes a guide member 340, which can connect one of the diverter channels to the converging channel 330. It should be noted that the magnetic driver 200 can be moved from different diverter channels to the same converging channel 330 to achieve confluence, or from the same converging channel 330 to different diverter channels to achieve diversion.

[0058] Specifically, such as Figure 4As shown, there are two diverter channels. For the convenience of subsequent description, they are respectively designated as a first diverter channel 310 and a second diverter channel 320. One end of the first diverter channel 310 and the second diverter channel 320 intersects with the converging channel 330, and the other ends extend in different directions. The guide member 340 includes a rotating shaft 342 disposed between the first diverter channel 310 and the second diverter channel 320 and a guide portion 341 disposed at the intersection. The rotating shaft 342 is connected to the output shaft of the drive motor. When the drive motor is in operation, the rotating shaft 342 rotates, and drives the guide portion 341 to rotate about the rotating shaft 342, thereby switching the position of the guide portion 341 so that one of the first diverter channel 310 and the second diverter channel 320 is connected to the converging channel 330.

[0059] More specifically, the guide portion 341 is driven to rotate and has a first position and a second position. In the first position, the first diversion channel 310 is connected to the merging channel 330. In the second position, the second diversion channel 320 is connected to the merging channel 330. Figure 5 As shown, the guide portion 341 has a first side wall 3411 and a second side wall 3412. In the first position, the first side wall 3411 of the guide member 340 is connected to the side wall of the first diversion channel 310, so that the magnetic driver 200 is guided by the first side wall 3411 to move from the first diversion channel 310 to the merging channel 330, or from the merging channel 330 to the first diversion channel 310. In the second position, as shown Figure 4 and Figure 5 As shown, the second side wall 3412 of the guide member 340 is connected to the side wall of the second diversion channel 320 .

[0060] The first diverter channel 310 and the merging channel 330 extend in the same direction, while the second diverter channel 320 and the merging channel 330 extend in opposite directions. Accordingly, the first sidewall 3411 is a flat surface, while the second sidewall 3412 is an arcuate surface. The second sidewall 3412 is configured as an arcuate surface to smoothly connect with the sidewall of the second diverter channel 320, thereby preventing the magnetic driver 200 from becoming stuck during diversion or merging.

[0061] In some embodiments, the conveying module 100 is any one of a straight line, a curved line or a wavy line. Figure 1 In the embodiment shown, the conveying module 100 is linear. Figure 6 In the embodiment shown, the conveying module 100 is curved, which can realize the change of conveying direction. The number of conveying modules 100 can be one or more. Figure 7In the illustrated embodiment, an annular magnetic drive conveying system is formed by combining a plurality of linear conveying modules 100 and a plurality of curved conveying modules 100. Further, two branch modules 300 are provided in the middle of the annular magnetic drive conveying system, and conveying modules 100 are connected to both ends of the branch modules 300, thereby forming a double-ring structure in the shape of a Chinese character "ri", which can be applicable to more working conditions.

[0062] In some embodiments, the conveying module 100 further includes a position sensor, and the position sensor is communicatively connected to each controller to real-time feedback the position of the magnetic drive element 200 and achieve the control of each coil winding.

[0063] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the knowledge scope of those of ordinary skill in the art to which the present utility model pertains. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
