[0034] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0035] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0036] like Figure 1 As shown, this application provides a magnetic drive transport system 1, including a stator assembly 11, a mover assembly 12, and a blocking member 13. The stator assembly 11 includes a stator body 111 and a coil winding 112 mounted on the stator body 111. The mover assembly 12 includes a mover body 122 and a permanent magnet array 121 disposed on the mover body 122, with the mover body 122 slidably connected to the stator body 111. The permanent magnet array 121 is disposed opposite to the coil winding 112. The blocking member 13 is connected to at least one of the stator body 111 and the mover body 122. The blocking member 13 includes a cover portion 132 disposed opposite to the coil winding 112, and a receiving space 14 for the magnetic drive transport system 1 is formed between the cover portion 132 and the stator body 111. Both the coil winding 112 and the permanent magnet array 121 are disposed within the receiving space 14. The projection of the cover portion 132 on the coupling surface covers the projection of the coil winding 112 on the coupling surface.

[0037] In the present application, the magnetic drive conveying system 1 is connected to at least one of the stator body 111 and the mover body 122 by arranging the blocking piece 13, and the cover structure part 132 of the blocking piece 13 is arranged to cover the projection of the coil winding 112 on the coupling surface of the magnetic drive conveying system 1. Thus, a semi-closed space structure is formed, which effectively prevents foreign matter such as dust particles from entering the containing space 14. Such a structure effectively avoids the adhesion of metal particles to the coil winding 112 and the surface of the permanent magnet array 121, thereby reducing the possibility of short circuit or increased resistance of the coil winding 112, and avoiding damage to the structure of the coil winding 112 caused by the extrusion of dust particles. At the same time, the arrangement of the blocking piece 13 also avoids the adhesion of metal debris affecting the magnetic field distribution of the permanent magnet array 121, thereby affecting the performance of the magnetic drive conveying system 1. As can be seen, the magnetic drive conveying system 1 of the present application can effectively improve the overall stability, reliability and safety of the system by the structural arrangement of the blocking piece 13, thereby reducing the failure risk, maintenance cost of the magnetic drive conveying system 1, and prolonging its service life.

[0038] It should be noted that in the present application, the coil winding 112 is arranged opposite to the permanent magnet array 121, and the magnetic field generated by the coil winding 112 interacts with the permanent magnet array 121 to drive the movement of the mover assembly. The coupling surface described in the embodiments of the present application refers to the surface of the coil winding 112 close to the permanent magnet array 121 after the coil winding 112 is energized, i.e., when a certain coil winding 112 is energized, the coil winding 112 generates a spatial magnetic field, and the coupling surface is a limited plane parallel to the surface of the coil winding 112 close to the surface of the permanent magnet array 121 within the magnetic field range.

[0039] Further, along the direction perpendicular to the surface of the coil winding 112, the plurality of coupling surfaces can be regarded as the spatial magnetic field range generated by the coil winding 112 after being energized. Therefore, the embodiments of the present application limit the width projection of the cover structure part 132 on the coupling surface to cover the width projection of the coil winding 112 on the coupling surface, i.e., the coverage range of the cover structure part 132 in the width direction is greater than the coverage range of the magnetic field of the coil winding 112. Moreover, since the containing space 14 is formed between the cover structure part 132 and the stator body 111, the coil winding 112 and the permanent magnet array 121 are arranged in the containing space 14, so that the coverage range of the containing space 14 in the width direction is greater than the coverage range of the coil winding 112 in the width direction of the magnetic field.

[0040] On the one hand, such a design makes the particles outside the containing space 14 be blocked by the blocking piece 13 to ensure the cleanliness of the containing space 14. On the other hand, the particles outside the containing space 14 will not be attracted by the magnetic field generated by the coil winding 112, so as to ensure the cleanliness of the surface of the blocking piece 13, thereby making the blocking piece 13 have better blocking effect.

[0041] However, considering that there may be multiple stator assemblies 11 in the magnetic drive transport system 1, the coupling surface position of the magnetic drive transport system 1 will be different when the coil windings 112 at different positions are energized; therefore, the coupling surface in a general sense refers to an infinite plane located between the coil windings 112 and the permanent magnet array 121 and parallel to the surface of the coil windings 112 near the permanent magnet array 121. On the coupling surface in a general sense, the width projection of the cover portion 132 on the coupling surface covers the width projection of the coil windings 112 on the coupling surface, that is, the width of the cover member 13 is greater than the width of the coil windings 112. When external particles fall under gravity, the cover member 13 can effectively block the particles to prevent them from falling directly onto the surface of the coil windings 112; and it can be understood that the wider the width of the cover portion 132, the more difficult it is for external particles to adhere to the surface of the coil windings 112 when they fall naturally. Furthermore, the width direction described in the above embodiments is perpendicular to the conveying direction of the mover assembly 12, and intuitively can refer to the width direction of the stator body 111 or the width direction of the coil winding 112.

[0042] In addition, during the operation of the magnetic drive conveying system 1, the setting of the blocking component 13 ensures the stable output of the magnetic field inside the system, thereby ensuring the accuracy and stability of the moving component 12 when it moves, improving the conveying efficiency of the system, and thus improving the overall efficiency of the production line and the quality of the products produced.

[0043] In such Figure 1 In the illustrated embodiment, the blocking member 13 is connected to the stator body 111, thereby forming the receiving space 14 of the stator assembly 11. This design allows the blocking member 13 to always cover the receiving space 14. When the rotor assembly 12 is running, the blocking member 13 is relatively stationary with respect to the stator body 111, thus providing continuous protection for the receiving space 14 and preventing external metal impurities from entering the receiving space 14. Furthermore, this design makes the installation and maintenance of the blocking member 13 simpler and more convenient, and also simplifies the mechanical structure, reducing design complexity and manufacturing costs. In other alternative embodiments, the blocking member 13 can also be configured to be connected to the rotor body 122 and move with the rotor body 122, thereby forming the receiving space 14 of the rotor assembly 12. In this embodiment, the blocking member 13 can move with the rotor body 122; therefore, regardless of how the rotor body 122 moves, the blocking member 13 can provide real-time protection for the receiving space 14, suitable for high-speed or frequently moving magnetic drive conveyor systems. Furthermore, since the blocking member 13 can move together with the moving body 122, it makes it easier for metal impurities that fall onto the blocking member 13 to be automatically removed during the movement. Therefore, this application does not impose any limitations on this.

[0044] It should be noted that, for ease of explanation and brevity, the width direction X, extension direction Y, and vertical direction Z are specifically provided as reference directions in the accompanying drawings. Furthermore, the width direction X, extension direction Y, and vertical direction Z are mutually perpendicular. The extension direction Y should be understood as a direction parallel to the direction in which the magnetic drive conveyor system 1 conveys the object, i.e., the direction of movement of the mover assembly 12. In addition, in the various embodiments described in this application, the phrase "structure a extends along direction b" should be understood as meaning that the extension of structure a has a component in direction b. That is, the extension direction of structure a may have a certain angle with direction b, and is not necessarily strictly parallel to direction b. This point will not be elaborated further in the following text.

[0045] Meanwhile, depending on the different usage scenarios and requirements of the magnetic drive conveying system 1, the projection area of ​​the blocking member 13 in the vertical direction Z can also be adjusted accordingly. For example, in one embodiment, the projection area of ​​the blocking member 13 in the vertical direction Z can be set to be the same as the projection area of ​​the stator body 111 in the vertical direction Z; while in another embodiment, the projection area of ​​the blocking member 13 can be set to be larger, thereby better blocking the accommodating space 14. Therefore, this application does not impose any limitations on this.

[0046] like Figure 2 As shown, in an optional embodiment, the blocking member 13 is connected to the stator body 111. The blocking member 13 also includes a support portion 131, one end of which is connected to the stator body 111, and the other end is connected to the cover portion 132. The mover body 122 surrounds and forms an isolation cavity 123. The cover portion 132 is located within the isolation cavity 123 and extends in the same direction as the isolation cavity 123, i.e., both extend along the extension direction Y.

[0047] from Figure 2As can be seen, the magnetic drive conveying system 1 designs the blocking piece 13 as a combination of the cover structure 132 and the support part 131, thereby forming a more complete closed structure, i.e., the support part is arranged on one side of the permanent magnet array, further improving the sealing of the containing space 14 and reducing the possibility of external impurities entering. At the same time, the mover assembly 12 is arranged by arranging the mover body 122 and the isolation cavity 123, and the cover structure 132 is located in the isolation cavity 123. Such a structure arrangement enables the cover structure 132 to pass through the isolation cavity 123 for avoidance during the movement of the mover assembly 12, without interfering with the operation of the mover assembly 12. In addition, the arrangement of the isolation cavity 123 enables a gap between the mover assembly 12 and the cover structure 132. During the operation of the mover assembly 12, even if there are dust particles on the cover structure 132, these dust particles can pass through the gap between the mover assembly 12 and the cover structure 132 (i.e., the top space of the isolation cavity 123 in the vertical direction Z) without affecting the operation of the mover assembly 12 or causing wear to its structure. It can be seen that the above structure arrangement effectively improves the stability and reliability of the magnetic drive conveying system 1 during operation, and also ensures the precision and efficiency of the magnetic drive conveying system 1 during operation, thereby meeting the production requirements of high precision, high efficiency and high reliability of the production line.

[0048] It should be noted that, in order to ensure the protection performance of the blocking piece 13, the projection area of the cover structure 132 of the present application in the width direction of the entire conveying line of the magnetic drive conveying system 1 covers the stator body 111, and at the same time, the support part 131 also uniformly extends along the extension direction Y, thereby ensuring the stability and safety of the cover structure 132 after installation. However, in other optional embodiments, the support part 131 can be designed as a hollow structure or multiple support parts 131 are arranged at intervals and uniformly arranged along the extension direction Y, considering cost control or lightweight, etc. Therefore, the present application does not limit this.

[0049] In optional embodiments, the mover body 122 includes a first body 1221, a second body 1222 and a third body 1223. The first body 1221 and the third body 1223 are arranged relative to the coil winding 112, and the first body 1221 is farther away from the coil winding 112 than the third body 1223. The first body 1221, the second body 1222 and the third body 1223 are arranged around the circumferential side of the cover structure 132 and form the isolation cavity 123.

[0050] The application splits the mover body 122 into a first body 1221, a second body 1222 and a third body 1223, so that the magnetic drive conveying system 1 can assemble the third body 1223, the second body 1222 and the first body 1221 in sequence without affecting the structure of the blocking piece 13 during assembly, and form an isolation cavity 123 for the blocking piece 13 to pass through. It can be seen that such a structural design significantly improves the efficiency and convenience during assembly, maintenance, replacement of parts and the like, effectively limiting the maintenance and installation costs of the magnetic drive conveying system 1. Alternatively, in some embodiments, the first body, the second body and the third body are integrally formed to make the mover body have better structural strength.

[0051] In some optional embodiments, the structure of the mover assembly 12 can be adjusted according to actual working requirements, application scenarios and the like. For example: in an embodiment in which the conveyed object is an instrument that needs to be clamped, the mover assembly 12 can be designed to be installed on the side of the stator body 111 along the width direction X, so as to better clamp and operate the instrument. In this embodiment, the isolation cavity 123 can be designed as a semi-closed space, i.e., the side away from the clamped instrument is designed as an open structure. In this way, the support part 131 can be arranged on the side with the open structure to block the side, and part of the cover part 132 is arranged in the isolation cavity 123, and the other part extends from the open position of the isolation cavity 123, so as to form a more complete blocking structure, ensuring that foreign matter such as dust particles from the outside cannot fall into the containing space 14 from the side. Similarly, in other application scenarios, the structures of the mover assembly 12 and the blocking piece 13 can be adjusted correspondingly, and therefore the application does not limit this.

[0052] In the above-mentioned embodiment, as shown in Figures 7 to 9 , the conveyed object is an instrument that needs to be clamped, at this time, the magnetic drive conveying system 1 designs the mover assembly 12 to be installed on the side of the stator body 111 along the width direction X, and designs the isolation cavity 123 as a semi-closed space, which can be arranged on the side with the open structure to block the side, and part of the cover part 132 is arranged in the isolation cavity 123, and the other part extends from the open position of the isolation cavity 123. In this embodiment, one end of the third body 1223 is connected to the guide piece 151, and the other end is connected to the second body 1222. The second body 1222 is arranged along the vertical direction Z, and the first body 1221 is connected to the second body 1222 at the end away from the third body 1223. The first body 1221 extends along the width direction X, so that the mover body 122 forms a structure similar to a C letter, facilitating the arrangement of the blocking piece 13.

[0053] And in the above-mentioned embodiment, as shown in Figure 2 , Figures 6 to 9In the shown embodiment, the third body 1223 is in a number of two, and the two third bodies 1223 are arranged along the width direction X and surround the cavity opening 1231 of the isolation cavity 123, and the isolation cavity 123 communicates with the accommodation space 14 through the cavity opening 1231. Along the extension direction Y, the orthographic projection of the support part 131 at least partially coincides with the orthographic projection of the cavity opening 1231.

[0054] In the operation of the magnetic drive conveying system 1, the mover assembly 12 moves along the extension direction Y under the excitation of the coil winding 112. In the moving process, the cover part 132 of the blocking piece 13 avoids the isolation cavity 123, and the support part 131 avoids the cavity opening 1231. The structure of the mover assembly 12 is arranged so that it does not interfere with the structure of the blocking piece 13 during operation, thereby ensuring the stability, safety and reliability of the magnetic drive conveying system 1 during operation. At the same time, since the mover assembly 12 and the blocking piece 13 are relatively independent, such a design also ensures that the blocking piece 13 can be arranged on the entire conveying line of the magnetic drive conveying system 1, further enhancing the protection ability of the magnetic drive conveying system 1 against external impurities.

[0055] In an optional embodiment, the mover assembly 12 includes a cooperating piece 152, and the stator assembly 11 includes a guide piece 151 extending along the extension direction Y. The cooperating piece 152 is connected with the guide piece 151 in cooperation, and the two form a guide assembly 15 of the magnetic drive conveying system 1.

[0056] The magnetic drive conveying system 1 of the present application is connected with the guide piece 151 and the cooperating piece 152 in cooperation, so that when the mover assembly 12 moves along the extension direction Y, the guide assembly 15 can effectively reduce the deviation and vibration of the mover assembly 12, thereby improving the movement precision of the system. At the same time, such a structure arrangement also enables the magnetic drive conveying system 1 to always maintain precise movement trajectory and position control, meeting the high-precision processing requirements. In addition, the guide assembly 15 can also avoid collision or interference between the mover assembly 12 and the blocking piece 13, thereby improving the reliability, safety and stability of the magnetic drive conveying system 1.

[0057] Of course, in another optional embodiment, the magnetic drive conveying system 1 can also be arranged such that the stator assembly 11 includes the cooperating piece 152, and the mover assembly 12 includes the guide piece 151 extending along the extension direction Y, thereby forming the guide assembly 15 of the magnetic drive conveying system 1. Similarly, the deviation and vibration of the mover assembly 12 can be effectively reduced, thereby improving the movement precision of the system. Therefore, the present application does not limit this.

[0058] In an optional embodiment, the vertical distance between the cover structure 132 and the surface of the coil winding 112 opposite to the stator assembly 11 is a first distance M. In actual installation and use, the specific structure of the magnetic drive conveying system 1 will be adjusted accordingly due to different use scenarios and user needs.

[0059] For example, in an optional embodiment, the coil winding 112 needs to be arranged in the vertical direction Z because the permanent magnet array 121 of the mover assembly 12 is a double-sided magnet. At this time, the surface of the coil winding 112 facing the mover assembly 12 is further close to the surface of the cover structure 132 facing the stator assembly 11. In order to limit the overall volume of the magnetic drive conveying system 1 and achieve the miniaturization requirement of the system, the first distance M is set to be greater than or equal to 25 mm and less than or equal to 35 mm in this embodiment. Specifically, it can be 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, or 35 mm. In actual application, if the first distance M is too small, the overall size of the accommodation space 14 will be limited, affecting the installation of the coil winding 112. If the first distance M is too large, the overall volume of the magnetic drive conveying system 1 will be large, and the utilization rate of the internal accommodation space 14 will be reduced.

[0060] In another optional embodiment, the permanent magnet array 121 of the mover assembly 12 is a single-sided magnet, and the coil winding 112 is arranged in the width direction X. Therefore, the magnetic drive conveying system 1 needs to correspondingly expand the size of the accommodation space 14 to ensure that the permanent magnet array 121 can be arranged between the coil winding 112 and the cover structure 132. Therefore, in this embodiment, the first distance M is set to be greater than or equal to 60 mm and less than or equal to 80 mm. Specifically, it can be 60 mm, 61 mm, 62 mm, 63 mm, 64 mm, 65 mm, 66 mm, 67 mm, 68 mm, 69 mm, 70 mm, 71 mm, 72 mm, 73 mm, 74 mm, 75 mm, 76 mm, 77 mm, 78 mm, 79 mm, or 80 mm. Similarly, in actual application, if the first distance M is too small, the overall size of the accommodation space 14 will be limited, resulting in too close spacing between the coil winding 112 and the permanent magnet array 121, or even unable to install, thereby affecting the normal assembly and operation of the magnetic drive conveying system 1. If the first distance M is too large, the overall volume of the magnetic drive conveying system 1 will be large, and the utilization rate of the internal accommodation space 14 will be reduced.

[0061] Similarly, in some other optional embodiments, the magnetic drive conveying system 1 can have a larger size of the permanent magnet array 121, or the motor and other structures need to be arranged in the accommodation space 14, or part of the structure of the mover assembly 12 needs to occupy part of the accommodation space 14. At this time, the magnetic drive conveying system 1 needs to further expand the size of the accommodation space 14, so the first distance M is set to be greater than or equal to 100 mm and less than or equal to 140 mm. Specifically, it can be 100 mm, 101 mm, 102 mm, 103 mm, 104 mm, 105 mm, 106 mm, 107 mm, 108 mm, 109 mm, 110 mm, 111 mm, 112 mm, 113 mm, 114 mm, 115 mm, 116 mm, 117 mm, 118 mm, 119 mm, 120 mm, 121 mm, 122 mm, 123 mm, 124 mm, 125 mm, 126 mm, 127 mm, 128 mm, 129 mm, 130 mm, 131 mm, 132 mm, 133 mm, 134 mm, 135 mm, 136 mm, 137 mm, 138 mm, 139 mm or 140 mm. Therefore, the present application does not limit this. In actual application, if the first distance M is too small, the overall specification of the accommodation space 14 will be limited, which will affect the installation of the coil winding 112 and the permanent magnet array 121, or the motor and part of the structure of the mover assembly 12 cannot be installed into the accommodation space 14, thereby affecting the normal assembly and operation of the magnetic drive conveying system 1. If the first distance M is too large, the overall volume of the magnetic drive conveying system 1 will be large, and the utilization rate of the internal accommodation space 14 will be reduced.

[0062] Therefore, the specific numerical range of the first distance M in the present application not only ensures that the size of the accommodation space 14 is appropriate and ensures the structural integrity of the magnetic drive conveying system 1, but also effectively limits the overall size of the magnetic drive conveying system 1. Such a setting makes the overall structure of the magnetic drive conveying system 1 more compact, thereby improving the internal space utilization rate, so that the magnetic drive conveying system 1 can meet more diversified application scenarios and adapt to more complex processing environments, thereby effectively expanding its application range.

[0063] In optional embodiments, along the width direction X, the blocking piece 13 further includes a bending portion 133 arranged on the opposite sides of the cover portion 132. One end of the bending portion 133 is connected with the cover portion 132, and the other end extends away from the first body 1221 of the third body 1223.

[0064] The magnetic drive conveying system 1 further expands the protection range of the blocking piece 13 through the design of the bending portion 133, and can better block pollutants such as metal scraps and dust from entering the containing space 14 from the side of the magnetic drive conveying system 1 along the width direction X.

[0065] In an optional embodiment, the third body 1223 includes an integral enclosing body 1223a and a placement body 1223b, the enclosing body 1223a is fixedly connected with the second body 1222, the bending portion 133 is located in the projection of the coil winding 112 on the enclosing body 1223a, and the enclosing body 1223a is farther away from the first body 1221 than the placement body 1223b.

[0066] As shown in Figure 3 , one end of the bending portion 133 is connected with the cover structure 132, and the other end extends away from the first body 1221 from the third body 1223. Therefore, the third body 1223 of the present application is correspondingly provided with the enclosing body 1223a and the placement body 1223b. The projection of the coil winding 112 on the enclosing body 1223a is located in the projection of the coil winding 112, and the placement body 1223b is used to connect the mover body 122 to the mover body 111. As can be seen, the enclosing body 1223a and the placement body 1223b are provided, so that the isolation cavity 123 forms a U-shaped groove at a position corresponding to the bending portion 133. When dust particles fall above the cover structure 132, even if the mover assembly 12 happens to move to this position at this time, the dust particles can only slide along the bending portion 133 into the groove of the isolation cavity 123. Then, as the mover assembly 12 moves, the dust particles slide to the ground and cannot enter the containing space 14 from the side. It can be seen that the design of the bending portion 133 significantly enhances the protection performance of the blocking piece 13, improves the protection ability of the side of the magnetic drive conveying system 1, further reduces the possibility of pollutant intrusion, and thus improves the stability, reliability and safety of the magnetic drive conveying system 1.

[0067] In an optional embodiment, the projection of the blocking piece 13 on the width direction X covers the projection of the guide assembly 15 on the width direction X. The structural design of the bending portion 133 enables the blocking piece 13 to further improve the protection ability of the side of the magnetic drive conveying system 1 along the width direction X, effectively reduces the possibility of particles falling into the containing space 14 from the side, and further improves the reliability and safety of the magnetic drive conveying system 1.

[0068] Please refer to Figure 2 , in an optional embodiment, as shown in Figure 4As shown, the bending portion 133 extends in a direction close to the coil winding 112, and the extending direction of the bending portion 133 forms an included angle A with the coupling surface, and the angle of the included angle A is greater than or equal to 90° and less than or equal to 110°; or, as shown, Figure 5 As shown, the bending portion 133 extends in a direction away from the coil winding 112, and the extending direction of the bending portion 133 forms an included angle A, and the angle of the included angle A is greater than or equal to 80° and less than 90°. Specifically, the angle of the included angle A can be 80°, 85°, 90°, 95°, 100°, 105° or 110°. The angle of the included angle A is set so that the bending portion 133 can form an inclined surface away from the accommodation space 14, or an inclined surface close to the accommodation space 14. In actual use, if the angle of the included angle A is designed to be too small, the bending portion 133 will bend too much towards the accommodation space 14, which may cause structural interference between the mover assembly 12 and the guide assembly 15. If the angle of the included angle A is designed to be too large, the bending portion 133 will bend too much away from the accommodation space 14, resulting in a larger size of the mover assembly 12 in the width direction X, and causing collision with other structures during operation.

[0069] As shown, Figure 4 As shown, when the size of the included angle A is in the range of 90° to 110°, the bending portion 133 will form an inclined surface close to the accommodation space 14. Accordingly, the structures on both sides of the isolation cavity 123 and the mover body 122 will also be correspondingly retracted, thereby further limiting the size of the structure of the mover body 122 and reducing the overall size of the magnetic drive conveying system 1. At the same time, the design of the included angle A also makes the position of the isolation cavity 123 corresponding to the bending portion 133 inclined inward, further ensuring that the particles falling into the groove position will not enter the accommodation space 14.

[0070] As shown, Figure 5 As shown, when the size of the included angle A is in the range of 80° to 90°, the bending portion 133 will form an inclined surface away from the accommodation space 14, thereby facilitating the sliding of dust particles from the surface of the mover body 122 or the bending portion 133, and further ensuring the protection performance of the blocking piece 13. At the same time, the angle setting of the bending portion 133 also increases the spacing between the mover body 122 and the stator body 111, ensuring that there is no interference between the structures of the mover body 122, the blocking piece 13 and the stator assembly 11, and ensuring the overall safety and stability of the magnetic drive conveying system 1.

[0071] In an optional embodiment, the vertical distance between the third body 1223 and the surface opposite to the coil winding 112 is a second distance N. The second distance N is greater than or equal to 20 mm and less than or equal to 32 mm. Specifically, the second distance N can be 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm or 32 mm. Similarly, in actual applications, if the second distance N is too small, it can limit the overall size of the accommodation space 14, affect the installation of the internal structure, or cause the structure of the mover assembly 12 to extend too much towards the stator body 111, resulting in mutual interference during operation. If the first distance M is too large, the overall size of the magnetic drive conveying system 1 will be large, and the utilization rate of the internal accommodation space 14 will be reduced.

[0072] The specific range of the second distance N in the present application effectively limits the overall structure size of the magnetic drive conveying system 1, avoids the distance between the mover body 122 and the stator body 111 being too far apart, and makes the overall size of the magnetic drive conveying system 1 larger, which limits the scope of application.

[0073] In an optional embodiment, the mover assembly 12 further comprises a magnetic sensor 16 connected to the mover body 122. The stator assembly 11 further comprises a magnetic scale 17 arranged opposite to the magnetic sensor 16, and the magnetic scale 17 extends along the extension direction Y. As shown in Figure 6 The magnetic scale 17 is located outside the accommodation space 14 and is arranged on the side surface of the stator body 111 in the width direction X. The present application arranges the support part 131 between the magnetic sensor 16 and the permanent magnet array 121, so that the support part 131 forms a physical barrier and plays a physical isolation role. Such a structural design effectively avoids the direct magnetic field interference of the permanent magnet array 121 on the magnetic sensor 16, so that the magnetic sensor 16 can independently and accurately perceive the magnetic field change of the magnetic scale 17. At the same time, such a structural design can also avoid the interference of the permanent magnet array 121 on the magnetic sensor 16, thereby improving the measurement accuracy of the real-time motion position of the mover assembly 12 by the magnetic drive conveying system 1 and ensuring the reliability of the measurement result.

[0074] In the embodiment as shown in Figure 6 The guide assembly 15 is also located between the magnetic sensor 16 and the permanent magnet array 121. As can be seen, the structural arrangement of the present application makes the support part 131 and the guide assembly 15 simultaneously act as a physical barrier, thereby better avoiding the direct magnetic field interference of the permanent magnet array 121 on the magnetic sensor 16, further improving the measurement accuracy of the real-time motion position of the mover assembly 12 by the magnetic drive conveying system 1, and ensuring the reliability of the measurement result.

[0075] In the embodiment as shown in Figure 7In the embodiment shown, the magnetic scale 17 is arranged on the surface of the support portion 131 away from the permanent magnet array 121 in the width direction X.

[0076] Similarly, the support portion 131 of the magnetic drive conveying system 1 can form a physical barrier to physically isolate the permanent magnet array 121, thereby effectively avoiding direct magnetic field interference of the permanent magnet array 121 on the magnetic sensor 16. As can be seen from the figure, the magnetic scale 17 and the magnetic sensor 16 are both arranged in the accommodation space 14, so that the magnetic scale 17 and the magnetic sensor 16 can be ensured not to be affected by the attachment of dust particles, further ensuring the measurement accuracy of the magnetic drive conveying system 1 on the real-time movement position of the mover assembly 12, and ensuring the reliability of the measurement result.

[0077] Of course, in other alternative embodiments, the arrangement of the magnetic sensor 16 and the magnetic scale 17 can also be adjusted accordingly according to different application scenarios and user requirements of the magnetic drive conveying system 1. For example, in the embodiment in which the size of the accommodation space 14 is limited, the magnetic scale 17 is arranged in the accommodation space 14 and on the surface of the stator body 111 away from the support portion 131 in the vertical direction Z; or the magnetic drive conveying system 1 can not be provided with the magnetic scale 17, and the magnetic sensor 16 is directly connected to the coil winding 112 and arranged towards the permanent magnet array 121. When the mover assembly 12 moves along the extension direction Y, the magnetic sensor 16 detects the magnetic field signal of the permanent magnet array 121. Such an arrangement enables the magnetic sensor 16 to directly detect the magnetic field change of the permanent magnet array 121 to determine the accurate position of the mover assembly 12, thereby further improving the space utilization of the magnetic drive conveying system 1 and controlling the production cost. Therefore, the present application does not limit the arrangement position of the magnetic scale 17 and the magnetic sensor 16.

[0078] In the embodiment shown in FIG. 1, Figure 6 In the embodiment shown in FIG. 1, Figure 7 In the embodiment shown in FIG. 1,

[0079] The structural layout of the permanent magnet array 121 and the coil winding 112 ensures that the overall magnetic field distribution of the permanent magnet array 121 is more uniform, avoiding the problems of magnetic field concentration or unevenness, and improving the overall magnetic field distribution effect of the system, so that the magnetic field utilization rate is higher. Moreover, since the first magnet 1211 and the second magnet 1212 are respectively located on the two sides of the coil winding 112, such a structural design enhances the magnetic field interaction between the permanent magnet array 121 and the coil winding 112, thereby improving the driving force of the system, reducing energy loss, and further improving the overall operation efficiency of the system, reducing energy consumption. In addition, such a design also avoids the phenomenon of heat concentration or local overheating, improving the operation stability of the system.

[0080] In another optional embodiment, as shown in Figure 8 , the first magnet 1211 and the second magnet 1212 are respectively arranged on the two sides of the coil winding 112 along the vertical direction Z.

[0081] In Figure 8 the embodiment shown, the magnetic drive conveying system 1 lays the coil winding 112 horizontally and arranges the first magnet 1211 and the second magnet 1212 on the two sides of the coil winding 112 along the vertical direction Z, so that the height of the accommodation space 14 in the vertical direction Z is smaller, thereby limiting the overall height of the magnetic drive conveying system 1, so that it can be applied to the use scene with limited height space.

[0082] In Figure 9 the embodiment shown, similar to the embodiment shown in Figure 7 , the first magnet 1211 and the second magnet 1212 of the permanent magnet array 121 are respectively arranged on the two sides of the coil winding 112 along the width direction X. But in Figure 9 the embodiment shown, the magnetic drive conveying system 1 arranges the motor and other components in the accommodation space 14. Such a structural arrangement enables the magnetic drive conveying system 1 to also protect other components of the magnetic drive conveying system 1 through the blocking piece 13, further improving the stability, reliability and safety of the magnetic drive conveying system 1 during operation, prolonging its service life.

[0083] In the actual assembly process of the magnetic drive conveying system 1, the magnetic drive conveying system 1 can include a multi-layer structure, and therefore the stator assembly 11 and the mover assembly 12 need to be capable of performing transportation work between the multi-layer structure. In such an embodiment, the magnetic drive conveying system 1 further includes a transfer stator assembly connected with the linear motor and used for splicing with the stator assembly 11 at different positions, the transfer stator assembly includes a transfer stator body and a coil winding mounted on the transfer stator body, and the blocking piece 13 is arranged on the transfer stator body. In the actual use process, the mover assembly 12 moves on the stator assembly 11 along the extension direction Y and performs transportation work, when the mover assembly 12 moves to the transfer stator assembly, it will be separated from the stator body 111, at the same time, it will be in line with the transfer stator body, and the permanent magnet array 121 of the mover assembly 12 will correspond to the coil winding mounted on the transfer stator body. After the mover body 122 is completely combined with the transfer stator body, the transfer stator assembly will drive the mover body 12 and the blocking piece 13 to move between different levels, so as to realize the layer changing operation. After the layer changing is successful, the mover assembly 12 is separated from the transfer stator assembly, and at the same time, it is in line with the mover assembly 11 of the layer, and continues to perform the transportation work.

[0084] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
