[0040] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the accompanying drawings.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0044] The present application proposes a magnetic drive conveying system. The magnetic drive conveying system includes a mover and a stator conveying line, which form a coordinated power and motion based on the principle of magnetic coupling, realizing stable conveying of materials and flexible adjustment of the transfer path of materials.

[0045] The bottom of the mover is integrated with a permanent magnet structure formed by a plurality of permanent magnets arranged in a permanent magnet array at a predetermined interval, which can stably generate a constant magnetic field. The stator conveying line generates a magnetic force by energizing the built-in coil assembly to drive the permanent magnet array of the mover, thereby driving the mover to move along the track of the stator conveying line. The constant magnetic field formed by the permanent magnet array itself can form a dynamic magnetic coupling effect with the alternating magnetic field generated by the energization of the coil assembly of the stator conveying line. When the direction and size of the current in the coil assembly change, the polarity and intensity of the alternating magnetic field will change synchronously, thereby generating a periodic repulsive or attractive interaction force with the constant magnetic field of the permanent magnet array. Specifically, after the alternating magnetic field generated by the energization of the coil assembly of the stator conveying line is coupled with the magnetic field of the permanent magnet array of the mover, a continuous and directional electromagnetic driving force is formed, which directly acts on the mover body to drive the mover to move stably along the track of the stator conveying line, thereby completing the automatic transfer of materials between different stations.

[0046] The stator conveying line specifically comprises a first linear stator, a second linear stator and a reversing stator 100. The first linear stator and the second linear stator are both linearly arranged stator structures, and both are internally provided with linear coil arrays of the same type as the coil assembly of the stator conveying line, which can generate directional magnetic driving force along the extension direction of the stator after being electrified, and can independently drive the mover to move linearly along the linear track stably, thereby serving as a conveying unit for realizing the linear segment transfer of the material in the magnetic driving conveying system. The first linear stator and the second linear stator are respectively arranged on the first direction and the second direction extension paths of the reversing stator 100, and are connected to the corresponding sides of the reversing stator 100 at the end close to the reversing stator 100, thereby receiving the mover transmitted by the reversing stator 100 and continuously providing driving force for the linear motion of the mover. The reversing stator 100 can realize the path switching of the mover between the first linear stator and the second linear stator through the adjustment of its own structure, and the three components cooperate to form a complete conveying track with the functions of linear conveying and direction switching, thereby further improving the flexibility of the material transfer path.

[0047] With reference to Figure 1 and Figure 2 The reversing stator 100 comprises a first coil plate 10 and a second coil plate 20. The second coil plate 20 is in a different plane from the first coil plate 10 and can translate relative to the first coil plate 10, so as to be spliced with the first coil plate 10 to form a first splicing state and a second splicing state. When the second coil plate 20 and the first coil plate 10 are in the first splicing state, they jointly generate magnetic driving force for driving the mover to move in the first direction, thereby driving the mover to move in the direction of the first linear stator and enter the conveying track of the first linear stator. When the second coil plate 20 and the first coil plate 10 are switched to the second splicing state, they jointly generate magnetic driving force for driving the mover to move in the second direction, which is arranged at an angle with the first direction, thereby driving the mover to move in the direction of the second linear stator and enter the conveying track of the second linear stator. The reversing stator 100 realizes the switching of the direction of the magnetic driving force through the adjustment of the splicing state of its own coil plate, and can complete the path switching of the mover between the first linear stator and the second linear stator without additional guide structure, thereby cooperating with the first linear stator and the second linear stator to form a complete conveying track with the functions of linear conveying and direction switching, and further improving the flexibility of the material transfer path.

[0048] Based on the above embodiments, by arranging the second coil plate 20 and the first coil plate 10 in different planes and enabling the second coil plate 20 to translate relative to the first coil plate 10, the first splicing state and the second splicing state are formed, and in different splicing states, the first coil plate 10 and the second coil plate 20 can jointly generate a magnetic driving force for driving the mover to move in the first direction and the second direction arranged at an angle. This structural design can realize the movement of the mover in different angular directions without the need for additional guide structures for the stator, thereby eliminating the design and assembly steps of the guide structure, simplifying the overall structure of the stator, reducing the volume accordingly, and reducing the manufacturing cost and assembly difficulty. In addition, the problem of reduced movement precision of the mover caused by the mechanical gap of the guide structure can be avoided, and finally the stator can meet the application requirements of small-sized and high-precision magnetic driving conveying systems.

[0049] In the specific implementation structure of the commutating stator 100, the first coil plate 10 is provided with a first inlet and outlet end 11, and the second coil plate 20 is correspondingly provided with a second inlet and outlet end 21. The two end portions jointly serve as a key port for the mover to enter and exit the commutating stator 100, and directly adapt to the movement trajectory of the mover in the commutating stator 100. When the second coil plate 20 and the first coil plate 10 are spliced into the first splicing state, the projection of the first inlet and outlet end 11 and the second inlet and outlet end 21 in the first direction at least presents a coincident state. This positional relationship allows the mover to smoothly enter and exit the commutating stator 100 in the first direction, ensuring the continuity of the movement of the mover in the first direction. When the two are switched to the second splicing state, the first inlet and outlet end 11 and the second inlet and outlet end 21 form at least a partially misaligned layout in the first direction. This misaligned design can adapt to the trajectory requirements of the movement of the mover in the second direction at an angle to the first direction, ensuring the stability and accuracy of the movement of the mover in the second direction into and out of the commutating stator 100.

[0050] For reference Figure 3Further, in the implementation structure of the commutating stator 100, the first coil plate 10 and the second coil plate 20 are both designed in the structure of right-angled triangle, wherein the first coil plate 10 is provided with a first straight side 12 extending along the first direction, a first in-out end 11 perpendicular to the first straight side 12, and a first slant side 13 at an angle with the first straight side 12; the second coil plate 20 is provided with a second straight side 22 parallel to the first straight side 12, a second in-out end 21 perpendicular to the second straight side 22, and a second slant side 23 parallel to the first slant side 13, and the two structures are adaptively matched. When the second coil plate 20 and the first coil plate 10 are in the first splicing state, the first slant side 13 of the first coil plate 10 and the second slant side 23 of the second coil plate 20 are aligned and spliced with each other, and together enclose a rectangular area, and in this state, the projection of the first in-out end 11 and the second in-out end 21 along the first direction completely coincides, so that the mover can freely enter and exit the commutating stator 100 along the first direction. When the two are switched to the second splicing state, the first straight side 12 of the first coil plate 10 and the second straight side 22 of the second coil plate 20 are aligned and spliced with each other, thereby forming a parallelogram area, and in this case, the first in-out end 11 and the second in-out end 21 are completely misaligned along the first direction, and the misalignment direction extends along the second direction, which can accurately adapt to the movement trajectory of the mover along the second direction, and ensure the smoothness of the mover entering and exiting the commutating stator 100 along the second direction.

[0051] Reference Figure 1 In some embodiments, the commutating stator 100 includes two support and drive components, a base 30 and a translation drive assembly 40: the first coil plate 10 is fixedly connected with the base 30, so as to determine the basic installation position of the first coil plate 10 in the commutating stator 100, and ensure that it always remains stable during work; the translation drive assembly 40 is also fixedly connected with the base 30, and at the same time, the assembly is in transmission connection with the second coil plate 20, and its core function is to drive the second coil plate 20 to move linearly along the translation path perpendicular to the first direction, and by controlling the linear movement of the second coil plate 20, the second coil plate 20 and the first coil plate 10 can be accurately and stably switched between the first splicing state and the second splicing state, thereby ensuring the flexible adjustment of the driving direction of the mover by the commutating stator 100.

[0052] In the specific implementation structure of the commutating stator 100, the commutating stator 100 further comprises two large support and driving components: the base 30 and the translation driving assembly 40. The first coil plate 10 is fixedly connected with the base 30, so as to determine the basic installation position of the first coil plate 10 in the commutating stator 100 and ensure that the first coil plate 10 always remains stable in position during the working process. The translation driving assembly 40 is also fixedly connected with the base 30, and at the same time, the assembly establishes a transmission connection relationship with the second coil plate 20. The function of the translation driving assembly 40 is to drive the second coil plate 20 to move linearly along a translation path perpendicular to the first direction. By controlling the linear movement of the second coil plate 20, the second coil plate 20 and the first coil plate 10 can be accurately and stably switched between the first splicing state and the second splicing state, so as to ensure the flexible adjustment of the commutating stator 100 to the driving direction of the mover.

[0053] The translation driving assembly 40 can adopt various mechanical structures suitable for linear driving requirements, and is used to drive the second coil plate 20 to move accurately along a translation path perpendicular to the first direction. In one embodiment, the translation driving assembly 40 can be a ball screw nut translation assembly, which mainly comprises a servo motor, a ball screw and a ball screw nut. The servo motor is fixedly connected with the base 30 and the output shaft is connected with the ball screw arranged perpendicular to the first direction. The ball screw nut is sleeved on the ball screw and is fixed with the second coil plate 20. When the servo motor drives the ball screw to rotate, the ball screw nut converts the rotary motion into linear motion, thereby driving the second coil plate 20 to translate. This structure has high transmission accuracy and can realize the position fine adjustment of the second coil plate 20. The translation driving assembly 40 can be a gear and rack translation assembly, which comprises a driving motor, a driving gear and a rack. The driving motor is fixed on the base 30, the driving gear is connected with the output shaft of the motor, and the rack is fixed on the bottom of the second coil plate 20 perpendicular to the first direction and is engaged with the driving gear. When the driving motor drives the driving gear to rotate, the rack drives the second coil plate 20 to move linearly. This structure has high transmission efficiency and fast response speed. The translation driving assembly 40 can be a pneumatic push rod translation assembly, which comprises a pneumatic cylinder, a pneumatic push rod and an electromagnetic valve. The pneumatic cylinder is fixed on the base 30, the pneumatic push rod is arranged in the same direction as the translation path and is connected with the second coil plate 20 at the extension end, and the electromagnetic valve controls the pneumatic cylinder to drive the push rod to extend and retract, thereby driving the second coil plate 20 to translate. This structure has low cost and simple operation. Regardless of the structure, the translation driving assembly 40 can convert the power into the linear translation force of the second coil plate 20 through mechanical transmission, realize the stable switching of the second coil plate 20 between the first splicing state and the second splicing state, and ensure the adjustment efficiency of the commutating stator 100 to the driving direction of the mover.

[0054] To further improve the stability and precision of the translation of the second coil plate 20, a slide rail (not shown) is specially arranged on the base 30, and the extension direction of the slide rail is completely consistent with the translation path of the second coil plate 20, that is, arranged along the direction perpendicular to the first direction. At the same time, the side of the second coil plate 20 facing the base 30 is provided with a sliding block corresponding to the position of the slide rail, and the sliding block and the slide rail form a close sliding fit. The combination of the slide rail and the sliding block can provide precise guidance for the translation of the second coil plate 20, strictly limit the movement track of the second coil plate 20, avoid the offset, shaking or jamming of the second coil plate 20 during translation, and also play a certain supporting role for the second coil plate 20, disperse the driving force received by the second coil plate 20, and reduce the frictional resistance in the translation process. With the sliding fit of the slide rail and the sliding block, the displacement precision and motion stability of the second coil plate 20 are significantly improved when the translation driving assembly 40 drives the second coil plate 20 to move, so that the switching of the second coil plate 20 and the first coil plate 10 between the first splicing state and the second splicing state is more precise, and the reliability of the commutating stator 100 for adjusting the driving direction of the mover is further guaranteed.

[0055] Alternatively, to ensure that the second coil plate 20 can obtain stable power supply to generate magnetic driving force in different splicing states, a power supply mechanism (not shown) is further arranged on the base 30, which includes a first power supply part and a second power supply part, which are arranged on the base 30 along the translation path of the second coil plate 20, and correspond to the first splicing state and the second splicing state of the second coil plate 20 respectively. The second coil plate 20 is provided with a power obtaining mechanism (not shown) matched therewith, which forms an electrical connection with the coil of the second coil plate 20 and is the core component for the second coil plate 20 to obtain electrical energy: when the translation driving assembly 40 drives the second coil plate 20 to move to the first splicing state, the power obtaining mechanism on the second coil plate 20 and the first power supply part of the base 30 realize butt joint conduction, and the electrical energy is transmitted to the coil of the second coil plate 20 through the first power supply part and the power obtaining mechanism, providing working power for the second coil plate 20; when the translation driving assembly 40 drives the second coil plate 20 to switch to the second splicing state, the power obtaining mechanism and the second power supply part of the base 30 complete butt joint conduction, and the second power supply part continuously supplies power to the coil of the second coil plate 20 through the power obtaining mechanism. The cooperation design of the power supply mechanism and the power obtaining mechanism can automatically realize the switching of the power supply link according to the splicing state of the second coil plate 20, ensure that the second coil plate 20 can stably obtain power in the first splicing state and the second splicing state, and further ensure that it and the first coil plate 10 can generate the required magnetic driving force, and guarantee the continuity and reliability of the commutating stator 100 for adjusting the driving direction of the mover.

[0056] In some embodiments, to further improve the positional accuracy and structural stability of the second coil plate 20 and the first coil plate 10 in the spliced state, the first coil plate 10 is provided with a positioning protrusion (not shown), and the second coil plate 20 is provided with a positioning recess (not shown) corresponding to the position of the positioning protrusion, and the two form a matched positioning structure. When the second coil plate 20 is moved to the first splicing state with the first coil plate 10 by the translation driving assembly 40, the positioning protrusion of the first coil plate 10 will be accurately embedded in the positioning recess of the second coil plate 20, and the relative displacement of the two in the plane will be limited by the engagement relationship of the protrusion and the recess, avoiding positional deviation after splicing; when the second coil plate 20 is switched to the second splicing state under the driving of the translation driving assembly 40, the positioning protrusion is still embedded in the positioning recess, and the position of the second coil plate 20 is continuously limited by the engagement structure. The cooperation design of the positioning protrusion and the positioning recess can provide accurate positioning reference for the splicing of the first coil plate 10 and the second coil plate 20 in the two splicing states, effectively prevent the relative shaking of the two due to external force or magnetic driving force, ensure the stability of the magnetic field region formed after splicing, and further ensure the accurate direction and stable strength of the magnetic driving force generated by the two, thereby improving the reliability of the commutating stator 100 driving the commutating rotor.

[0057] Referring to Figure 1 Optionally, to ensure that the first coil plate 10 and the second coil plate 20 always maintain a relative positional relationship in space in different splicing states, an isolation support 50 is further provided between the first coil plate 10 and the second coil plate 20. The isolation support 50 is fixed to the surface of the first coil plate 10 facing the second coil plate 20, and its core function is to maintain a predetermined interlayer gap between the first coil plate 10 and the second coil plate 20. The setting of this predetermined interlayer gap can not only avoid the risk of circuit short circuit caused by direct contact between the first coil plate 10 and the second coil plate 20, and protect the coil assembly on the coil plate from being damaged, but also can provide sufficient space for the translational movement of the second coil plate 20 relative to the first coil plate 10, reduce the frictional interference between the two, and ensure the smoothness of the second coil plate 20 when switching the splicing state; at the same time, the accurate interlayer gap can also make the magnetic field generated by the first coil plate 10 and the second coil plate 20 form a more stable coupling effect, ensure that the magnetic driving force generated by the two in different splicing states meets the design requirements in strength and direction, and further improve the working stability and driving accuracy of the commutating stator 100.
