Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of magnet assembly, and in particular, to a magnet assembly device, a magnet assembly process, and a feeding mechanism. Background Art

[0002] The Halbach array is a magnet structure. By arranging multiple magnets to form a magnet array, the magnetic field on one side of the magnet array is increased, while the magnetic field on the other side is canceled to be close to zero, generating the strongest magnetic field with the least amount of magnets, thereby improving the performance of the motor. In the process of manufacturing the magnet array in the related art, it is difficult to assemble the magnets due to the repulsive or attractive magnetic force between the magnets, and the directions of the magnets are prone to be disordered, resulting in poor manufacturability. Summary of the Invention

[0003] The embodiments of the present application provide a magnet assembly device, a magnet assembly process, and a feeding mechanism, which solve the problem that it is difficult to assemble or feed the magnet array in the related art.

[0004] The embodiments of the present application adopt the following technical solutions:

[0005] In a first aspect, the embodiments of the present application provide a magnet assembly device, including: a transfer mechanism, a feeding mechanism, an assembly mechanism, and a connection mechanism. The transfer mechanism includes a transfer carrier and a transmission component. The transfer carrier has a plurality of transfer slots arranged side by side and capable of accommodating and positioning magnets. The transfer carrier has an assembly position and one or more feeding positions. The output end of the transmission component is connected to the transfer carrier, and the transmission component is used to drive the transfer carrier to move between the feeding position and the assembly position. A feeding mechanism is correspondingly arranged at the feeding position. When the transfer carrier is at the feeding position, the feeding mechanism is used to provide magnets with a predetermined magnetic pole direction to the transfer slots. An assembly mechanism is correspondingly arranged at the assembly position. The assembly mechanism includes an assembly carrier, a transfer component, and a pressing component. The assembly carrier has an assembly slot capable of accommodating and positioning a plurality of juxtaposed magnets. When the transfer carrier is at the assembly position, the transfer component is used to transfer the magnets in the transfer slots to the assembly slot, and the pressing component is used to press the plurality of magnets in the assembly slot along a predetermined arrangement direction. The connection mechanism is used to connect the plurality of magnets in the assembly slot.

[0006] The magnet assembly device provided by the embodiment of the present application, the transfer component in the transfer mechanism drives the transfer carrier to switch between the feeding position and the assembly position. When the transfer carrier is at the feeding position, the feeding mechanism corresponding to the feeding position can provide magnets with a predetermined magnetic pole direction to the transfer groove of the transfer carrier, and accommodate and position the magnets in the transfer groove. The transfer carrier is used to reduce the magnet spacing, realizing the rough positioning of multiple magnets on the transfer carrier. The magnets after rough positioning lack space for rotation and inclination, preventing the magnetic pole directions of the magnets from being disordered without external force constraint. When a predetermined number of magnets are installed in the transfer groove of the transfer carrier and the transfer carrier is located at the assembly position, the transfer component in the assembly mechanism transfers multiple magnets on the transfer carrier to the assembly groove of the assembly carrier, and presses multiple magnets in the assembly groove along the arrangement direction through the pressing component, realizing the fine positioning of multiple magnets. Multiple magnets in the assembly groove are connected through the connecting mechanism. The magnet assembly device can realize the assembly of Halbach arrays or similar magnet arrays with the number of magnets greater than or equal to 3, is applicable to the assembly of large-sized magnets and small-sized magnets, enables each magnet to maintain a predetermined magnetic pole direction, has good manufacturability of the magnet array, good assembly consistency, good reliability, and high assembly efficiency.

[0009] In an alternative implementation, the transfer component can be provided with a displacement sensor to detect whether the transfer carrier moves to a predetermined position, such as the feeding position or the assembly position, through the displacement sensor.

[0010] In an alternative implementation, multiple feeding mechanisms are arranged at intervals along the linear extension direction of the transfer component on the same side of the transfer component, and each feeding mechanism provides magnets with a predetermined magnetic pole direction and shape. The assembly carrier and the pressing component in the assembly mechanism are arranged on one side of the transfer component, and the transfer component in the assembly mechanism is arranged on the other side of the transfer component.

[0011] In an alternative implementation, the transfer carrier can include a connected base and a cover body. One side surface of the cover body has a plurality of first grooves distributed side by side. After the cover body is installed on the base, the base and the cover body jointly enclose a plurality of side-by-side transfer grooves, and the transfer carrier is easy to form and assemble.

[0012] In an alternative implementation, the transfer carrier is a single structural member, and a plurality of side-by-side transfer grooves are directly formed on the structural member.

[0013] In an alternative implementation, multiple transfer slots are arranged side by side, and a transfer carrier forms a partition wall between two adjacent transfer slots, that is, the opposite sides of the partition wall are adjacent transfer slots. The thickness of the partition wall can be less than the width of the transfer slot. When multiple magnets are correspondingly installed in multiple transfer slots, the distance between adjacent magnets can be reduced. When the transfer carrier is in the assembly position, the transfer component transfers multiple magnets in the transfer slot to the assembly slot, so that each magnet in the assembly slot maintains a predetermined magnetic pole direction.

The magazine has a trough capable of accommodating magnets arranged in a column, and a leakage end for the magnets to leak out is formed at the bottom of the trough. The blocking member is arranged side by side with the support, and the leakage end can be selectively arranged facing the blocking member or the support. When the leakage end faces the blocking member, the blocking member can block the leakage end. When the leakage end faces the support and the groove is facing upwards, the leakage end is in communication with the groove.

The magazine is stationary, and the movable frame is driven by the lateral displacement component to move in the X direction, so as to drive the blocking member and the support member to move synchronously in the X direction relative to the magazine, so that the leakage end of the magazine is arranged facing the blocking member or the support member.

The detection signal of the magnetic pole detection member is fed back to the controller. The controller can obtain the rotation angle required for the output end of the flipping assembly based on the predetermined magnetic pole direction of the magnet and the detection signal of the magnetic pole detection member.

[0128] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Although the description of the present application will be introduced in conjunction with some embodiments, this does not mean that the features of this application are limited to this implementation. On the contrary, the purpose of introducing the implementation as an application is to cover other alternatives or modifications that may extend based on the claims of the present application. In order to provide a deep understanding of the present application, many specific details will be included in the following description. The present application can also be implemented without using these details. In addition, in order to avoid confusing or obscuring the focus of the present application, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0129] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0130] It should be understood that in the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0131] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise clearly and specifically defined.

[0132] In the embodiments of the present application, "and / or" is merely an association relationship describing associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this article, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0133] The reference to "one embodiment" or "some embodiments" etc. described in this specification means that in one or more embodiments of the present application, specific features, structures, or characteristics described in connection with that embodiment are included. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but rather mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in another way.

[0134] In the production of a related art magnet array, it can be achieved by using tooling and manual assembly. There is a repulsive or attractive magnetic force between the magnets, making it difficult to assemble, and there are disadvantages such as poor manufacturability, poor assembly consistency, and poor reliability. In particular, in the case of manufacturing a magnet array with small-sized magnets, such as magnets with a long rectangular cross-section, without intervention, the magnets are prone to flipping, adsorbing, and misaligning, making it difficult to overcome the magnetic force of the small-sized magnets for assembly, easily causing the magnetic directions of the magnets to be disordered, and having a relatively large tolerance gap between the magnets, which affects the finished product performance of the magnet array.

[0135] In a related art magnet assembly process, referring to Figure 1 (a) to (d) therein, a carrier plate 11, a magnetic conductive sheet 12, a magnetic conductive rod 13, and a push rod 14 are used. The carrier plate 11 has a retaining wall 11a and a mounting groove 11b. As shown in Figure 1 (a) therein, first, a plurality of magnets 1 are arranged at intervals on the bottom surface of the mounting groove 11b of the carrier plate 11, and the plurality of magnets 1 are arranged in a predetermined magnetic pole direction. The arrows on the magnets 1 indicate the magnetic pole directions of the magnets 1; as shown in Figure 1 (b) therein, then, glue needles 15 are used to apply glue 16 to the side walls of the magnets 1; as shown in Figure 1 (c) therein, then, the magnetic conductive rod 13 is arranged on the tops of the plurality of magnets 1; as shown in Figure 1 (d) therein, finally, the push rod 14 is used to laterally push and press the magnets 1, and the plurality of magnets 1 are pressed between the retaining wall 11a and the push rod 14 until the plurality of magnets 1 are bonded. The above solution is applicable to the assembly of a magnet array with large-sized magnets 1. Referring to Figure 2In (a) to (c) of [reference], for the assembly of the small-sized magnet 1, when multiple magnets 1 are arranged between the magnetic conductive sheet 12 and the magnetic conductive rod 13 and are pushed and pressed by the push rod 14, the magnets 1 are prone to rotate and tilt in the under-constrained direction, resulting in the disorder of the directions of the magnets 1.

[0136] In another magnet assembly process of the related art, referring to Figure 3 (a) to (d) of [reference], a carrier plate 21, a magnetic conductive sheet 22, a first pressing jig 23 and a second pressing jig 24 are used. The carrier plate 21 has two retaining walls 21a and a mounting groove 21b. The mounting groove 21b is located between the two retaining walls 21a. The first pressing jig 23 is made of a magnetic isolation material and has a boss portion 23a. The second pressing jig 24 has a pressing surface. As Figure 3 shown in (a) of [reference], first, the magnetic conductive sheet 22 is arranged on the bottom surface of the mounting groove 21b of the carrier plate 21, and glue 25 is applied to the upper surface of the magnetic conductive sheet 22 and the inner surfaces of the retaining walls 21a; then, as Figure 3 shown in (b) of [reference], the magnets 1 on both sides are arranged at both ends of the mounting groove 21b in a predetermined magnetic pole direction, and the boss portion 23a of the first pressing jig 23 is inserted into the vacant positions between the magnets 1 at both ends. The magnets 1 at both ends are pressed by the first pressing jig 23, and the glue is cured by baking; then, as Figure 3 shown in (c) of [reference], the first pressing jig 23 is taken out, and glue 25 is applied between the magnets 1 at both ends; finally, as Figure 3 shown in (d) of [reference], magnets 1 in a predetermined magnetic pole direction are installed between the magnets 1 at both ends, and all the magnets 1 are pressed from the top by the second pressing jig 24, and the glue is cured by baking. In the above solution, glue 25 and magnets 1 are applied and installed twice, and pressure and baking are carried out twice. The process is complex, prone to glue overflow, making it difficult to assemble the middle magnets 1, and the assembly accuracy is low. The glue is prone to softening under high temperature and high humidity, resulting in the detachment of the magnets 1.

[0137] The embodiment of the present application provides a magnet assembly device, which can assemble multiple magnets 1 as shown in Figure 4 (a) of [reference] to obtain a magnet array as shown in Figure 4 (b) of [reference]. The number and shape of the magnets 1 in the magnet array are not limited. The process of assembling the magnet array by using the magnet assembly device is as follows: as Figure 5 (a) to (c) of [reference], first, magnets 1 with a predetermined magnetic pole direction are respectively loaded into multiple transfer slots 111 of the transfer carrier 110. The end face of each magnet 1 is marked with N representing the north pole and S representing the south pole, and the magnetic pole direction inside the magnet 1 is from S to N; as Figure 5 shown in (c) of [reference], the magnetic pole directions of the three magnets 1 are different; then, as Figure 5 shown in (d) of [reference], multiple magnets 1 in the transfer carrier 110 are pushed into the assembly carrier 310 along the large arrow direction; as Figure 5As shown in (e) and (f) thereof, a plurality of magnets 1 in the assembly groove 311 of the assembly carrier 310 are laterally pressed along the direction of the large arrow; finally, the plurality of magnets 1 are connected to form a magnet array.

[0138] Combined with Figures 6 to 8 , the magnet assembly device 1000 according to the embodiment of the present application includes: a transfer mechanism 100, a feeding mechanism 200, an assembly mechanism 300, and a connecting mechanism 400. The transfer mechanism 100 includes a transfer carrier 110 and a transmission component 120. The transfer carrier 110 has a plurality of transfer grooves 111 arranged side by side and capable of accommodating and positioning the magnets 1. The transfer carrier 110 has an assembly position 110b and one or more feeding positions 110a. The output end 120a of the transmission component 120 is connected to the transfer carrier 110. The transmission component 120 is used to drive the transfer carrier 110 to move between the feeding position 110a and the assembly position 110b. The feeding mechanism 200 is correspondingly arranged at the feeding position 110a. When the transfer carrier 110 is located at the feeding position 110a, the feeding mechanism 200 is used to provide the magnets 1 with a predetermined magnetic pole direction to the transfer grooves 111. The assembly mechanism 300 is correspondingly arranged at the assembly position 110b. The assembly mechanism 300 includes an assembly carrier 310, a transfer component 320, and a pressing component 330. The assembly carrier 310 has an assembly groove 311 capable of accommodating and positioning a plurality of juxtaposed magnets 1. When the transfer carrier 110 is located at the assembly position 110b, the transfer component 320 is used to transfer the magnets 1 in the transfer grooves 111 to the assembly groove 311, and the pressing component 330 is used to press the plurality of magnets 1 in the assembly groove 311 along a predetermined arrangement direction. The connecting mechanism 400 is used to connect the plurality of magnets 1 in the assembly groove 311.

[0139] Among them, as Figure 5 shown in (c) thereof, the plurality of transfer grooves 111 arranged side by side on the transfer carrier 110 are respectively used to accommodate a plurality of magnets 1 arranged in sequence in the magnet array. The transfer groove 111 can accommodate and position the magnet 1, which means that the magnet 1 can be accommodated and positioned in the transfer groove 111, and the magnet 1 will not rotate and tilt in the transfer groove 111.

[0140] As Figure 5 shown in (e) thereof, the assembly groove 311 on the assembly carrier 310 can accommodate and position a plurality of juxtaposed magnets 1, which means that the plurality of juxtaposed magnets 1 can be accommodated and positioned in the assembly groove 311, and the magnets 1 will not rotate and tilt in the assembly groove 311.

[0141] As Figure 5 shown in (e) and (f) thereof, the predetermined magnetic pole direction of the magnet 1 is the magnetic pole direction of the magnet 1 in the magnet array. Usually, the magnetic pole directions of two adjacent magnets 1 are different. The predetermined arrangement direction of the plurality of magnets 1 refers to the arrangement direction of the plurality of magnets 1 in the magnet array.

[0142] The magnet assembly device 1000 provided by the embodiment of the present application. The transfer component 120 in the transfer mechanism 100 drives the transfer carrier 110 to switch between the feeding position 110a and the assembly position 110b. When the transfer carrier 110 is located at the feeding position 110a, the feeding mechanism 200 corresponding to the feeding position 110a can supply the magnet 1 with a predetermined magnetic pole direction to the transfer groove 111 of the transfer carrier 110, and accommodate and position the magnet 1 in the transfer groove 111. The transfer carrier 110 is used to reduce the distance between the magnets 1, realizing the rough positioning of multiple magnets 1 on the transfer carrier 110. The magnet 1 after rough positioning lacks spatial rotation and inclination, preventing the magnetic pole directions of the magnets 1 from being disordered without external force constraint. When a predetermined number of magnets 1 are installed in the transfer groove 111 of the transfer carrier 110 and the transfer carrier 110 is located at the assembly position 110b, the transfer component 320 in the assembly mechanism 300 transfers multiple magnets 1 on the transfer carrier 110 to the assembly groove 311 of the assembly carrier 310, and presses multiple magnets 1 in the assembly groove 311 along the arrangement direction through the pressing component 330, realizing the fine positioning of multiple magnets 1. Multiple magnets 1 in the assembly groove 311 are connected through the connecting mechanism 400. The magnet assembly device 1000 can realize the assembly of a Halbach array or a similar magnet array with the number of magnets 1 greater than or equal to 3, is applicable to the assembly of large-sized magnets and small-sized magnets, enables each magnet 1 to maintain a predetermined magnetic pole direction, has good manufacturability of the magnet array, good assembly consistency, good reliability, and high assembly efficiency.

[0143] There are various optional implementation methods for arranging the transfer mechanism 100. The first arrangement method of the transfer mechanism 100 is a linear arrangement, and the second arrangement method of the transfer mechanism 100 is a circular arrangement. The following mainly takes the first transfer mechanism 100 as an example for explanation.

[0144] For the convenience of describing the orientation of the magnet assembly device, in the case where the transfer mechanism 100 adopts a linear arrangement, the direction of the linear displacement output by the transfer component 120 or the movement direction of the transfer carrier 110 is defined as the X direction, the transfer direction in which the transfer component 320 transfers the magnet 1 in the transfer groove 111 to the assembly groove 311 is defined as the Y direction, the vertical direction is the Z direction, and the X direction, Y direction, and Z direction are perpendicular to each other in pairs. The arrangement direction of multiple transfer grooves 111 in the transfer carrier 110 and the arrangement direction of multiple magnets 1 in the magnet array are also the X direction.

[0145] Refer to Figure 6 、 Figure 7 , the transfer mechanism 100 adopts a linear arrangement, the output end 120a of the transfer component 120 can output a linear displacement, and one or more feeding positions 110a and assembly positions 110b are arranged in a straight line.

[0146] One or more feeding positions 110a and assembly positions 110b are arranged in a straight line, and the feeding mechanism 200 and the assembly mechanism 300 can be arranged in a straight line. The transmission component 120 drives the transfer carrier 110 to flow between the feeding position 110a and the assembly position 110b.

[0147] Among them, the transmission component 120 can be various driving modules that can output linear displacement, such as linear motors, electric cylinders, combined control motors and synchronous belt linear slides, etc. The transmission component 120 can be provided with a displacement sensor to detect whether the transfer carrier 110 moves to a predetermined position, such as the feeding position 110a or the assembly position 110b, through the displacement sensor.

[0148] Exemplarily, refer to Figure 7 , a plurality of feeding mechanisms 200 are arranged at intervals on the same side of the transmission component 120 along the linear extension direction (X direction) of the transmission component 120, and each feeding mechanism 200 provides a magnet 1 with a predetermined magnetic pole direction and shape. The assembly carrier 310 and the pressing component 330 in the assembly mechanism 300 are arranged on one side of the transmission component 120, and the transfer component 320 in the assembly mechanism 300 is arranged on the other side of the transmission component 120.

[0149] There are various optional implementation methods for setting the transfer carrier 110. Two implementation methods of the transfer carrier 110 are exemplarily given below.

[0150] The first implementation method of the transfer carrier 110: Refer to Figure 9 , Figure 10 , the transfer carrier 110 can include a connected base 113 and a cover 114. One side surface of the cover 114 has a plurality of first grooves 1141 distributed side by side. The cover 114 is installed on the base 113, and the base 113 and the cover 114 jointly enclose a plurality of side-by-side transfer slots 111. This transfer carrier 110 is easy to mold and assemble. The base 113 and the cover 114 can be connected by fasteners or other means.

[0151] The second implementation method of the transfer carrier 110: The transfer carrier 110 is a single structural member, and a plurality of side-by-side transfer slots 111 are directly formed on this structural member.

[0152] When a plurality of transfer slots 111 are provided in the transfer carrier 110, refer to Figure 10 , Figure 11, a plurality of transfer grooves 111 are arranged side by side, and the transfer carrier 110 forms a partition wall 112 between two adjacent transfer grooves 111, that is, the opposite sides of the partition wall 112 are adjacent transfer grooves 111. The thickness A of the partition wall 112 can be less than the widths (B1, B2) of the transfer grooves 111. The thickness A of the partition wall 112 is the dimension of the partition wall 112 in the arrangement direction (X direction) of the magnets 1. The widths (B1, B2) of the transfer grooves 111 are the dimensions of the opposite side walls of the transfer grooves 111 in the arrangement direction (X direction) of the magnets 1.

[0153] When a plurality of magnets 1 are correspondingly installed in the plurality of transfer grooves 111, the distance between adjacent magnets 1 can be reduced. When the transfer carrier 110 is located at the assembly position 110b, the transfer assembly 320 transfers the plurality of magnets 1 in the transfer grooves 111 to the assembly grooves 311. The distance between the magnets 1 in the assembly grooves 311 is relatively small and they will not rotate and tilt, so that each magnet 1 in the assembly grooves 311 maintains a predetermined magnetic pole direction. In Figure 11 In the illustrated embodiment, different-width magnets 1 can be placed in adjacent transfer grooves 111, and the transfer grooves 111 can be set to different widths (B1, B2).

[0154] When setting the feeding mechanism 200, refer to Figures 12 to 15 , the feeding mechanism 200 includes a support 210, a feeding component 220, a magnetic pole detection component 230, a flipping component 240 and a pushing component 250. The support 210 has a groove 211 capable of accommodating the magnets 1, and at least part of the material of the support 210 is ferromagnetic material. The feeding component 220 is used to supply the magnets 1 to the groove 211. The magnetic pole detection component 230 is arranged on the support 210 and is used to detect the magnetic pole direction of the magnets 1 at the groove 211. The output end 240a of the flipping component 240 is connected to the support 210 and is used to drive the support 210 to rotate to adjust the orientation of the magnets 1. Combining Figure 16 , when the transfer carrier 110 is located at the feeding position 110a, the pushing component 250 is used to push the magnets 1 at the groove 211 into the transfer grooves 111.

[0155] The feeding mechanism 200 can supply a single magnet 1 with a predetermined magnetic pole direction to the transfer carrier 110 located at the feeding position 110a each time. The magnet 1 is provided to the groove 211 of the support member 210 by the feeding assembly 220, and the magnetic pole direction of the magnet 1 is detected by the magnetic pole detection member 230. When the magnetic pole direction of a certain magnet 1 does not conform to the expected direction, the orientation of the magnet 1 needs to be adjusted by the flipping assembly 240. When the magnetic pole direction of a certain magnet 1 conforms to the expected direction, there is no need to adjust the orientation of the magnet 1 through the flipping assembly 240. During the rotation of the support member 210 driven by the flipping assembly 240, the magnet 1 and the ferromagnetic material (such as iron, steel, etc.) of the support member 210 are magnetically adsorbed to a certain extent, and the magnet 1 remains in the groove 211 without falling off. When the magnetic pole direction of the magnet 1 reaches the expected direction, the magnet 1 with the expected magnetic pole direction is pushed out of the groove 211 of the support member 210 by the pushing assembly 250 and pushed into one of the transfer grooves 111 of the transfer carrier 110 located at the feeding position 110a.

[0156] When setting the support member 210, refer to Figure 15 , the support member 210 may include a cylindrical portion 212, an extension portion 213, and a plate-shaped portion 214. The extension portion 213 is connected to one end of the cylindrical portion 212, and the plate-shaped portion 214 is connected to the extension portion 213. In order to achieve the magnetic adsorption effect on the magnet 1, the plate-shaped portion 214 and / or the extension portion 213 can be made of ferromagnetic material.

[0157] When setting the groove 211, the cross-section of the groove 211 is adapted to the cross-section of the magnet 1 corresponding to the groove 211, that is, the cross-sections of the groove 211 and the magnet 1 are close in shape and size, so that the magnet 1 can be accommodated and positioned in the groove 211 without rotational inclination. The cross-sections of both the groove 211 and the magnet 1 are perpendicular to the extending direction (Y direction) of the groove 211. For example, the cross-section of the magnet 1 is rectangular, and the cross-section of the groove 211 is approximately rectangular, and their sizes are close.

[0158] When setting the support member 210 and the feeding assembly 220, refer to Figures 12 to 15 , the feeding assembly 220 includes a magazine 221 and a stopper 222. The magazine 221 has a trough 2211 capable of accommodating magnet 1 arranged in a column, and a leakage end 2212 for the magnet 1 to leak out is formed at the bottom of the trough 2211. The stopper 222 is arranged in parallel with the support member 210, and the leakage end 2212 can be selectively faced with the stopper 222 or the support member 210. Combining Figure 12 、 Figure 17 , when the leakage end 2212 faces the stopper 222, the stopper 222 can block the leakage end 2212. Combining Figure 13 、 Figure 18, when the leakage end 2212 faces the support member 210 and the groove 211 is arranged upward, the leakage end 2212 communicates with the groove 211.

[0159] In this embodiment, the support member 210, the blocking member 222 and the magazine 221 cooperate to peel off the lowermost magnet 1 in the chute 2211 and drop it into the groove 211 of the support member 210. A whole strip of magnets 1 is arranged in the chute 2211 of the magazine 221. When there is no object blocking at the leakage end 2212 at the bottom of the chute 2211, the magnet 1 can leak out from the leakage end 2212 under the action of gravity. Combining Figure 12 , Figure 17 , when the leakage end 2212 of the magazine 221 faces the blocking member 222, the blocking member 222 blocks the leakage end 2212 and the magnet 1 remains in the chute 2211. Combining Figure 13 , Figure 18 , when the leakage end 2212 of the magazine 221 faces the support member 210 and the groove 211 of the support member 210 is arranged upward, the single magnet 1 at the leakage end 2212 can fall into the groove 211 under the action of gravity. During the process of the object faced by the leakage end 2212 switching from the support member 210 to the blocking member 222, other magnets 1 near the leakage end 2212 in the chute 2211 are blocked by the blocking member 222 and remain in the chute 2211. The magazine 221 can be made of non-ferromagnetic materials such as copper, aluminum, plastic, etc., which is convenient for the magnet 1 in the chute 2211 to come out from the leakage end 2212 under the action of gravity.

[0160] When the flipping assembly 240 adjusts the orientation of the magnet 1, referring to Figure 4 in (a), the magnet array may include a plurality of cuboid magnets 1, and a predetermined angle is formed between the magnetic pole direction of the magnet 1 and the arrangement direction (X direction) of the plurality of magnets 1, such as 0°, ±10°, ±45°, ±90°, ±100°, 180°, etc. The arrow on the magnet 1 indicates the magnetic pole direction of the magnet 1. The positive and negative signs of the above angle are defined as follows: the deflection direction from the magnet 1 arrangement direction (X direction) to the magnet 1 magnetic pole direction, clockwise deflection is positive, and counterclockwise deflection is negative. Referring to Figure 13 , when assembling the magnet array, the columnar magnets 1 in the magazine 221 fall into the groove 211 of the support member 210 from the leakage end 2212. Referring to Figure 12 , when the magnetic pole direction of a certain magnet 1 does not meet the expected direction, by driving the support member 210 to rotate by -90°, +90° or 180° or other angles through the flipping assembly 240, the magnetic pole direction of the magnet 1 can be adjusted as required.

[0161] Exemplarily, such as Figure 4As shown in (a) of [description], in the magnet array, the angles between the magnetic pole directions of the respective magnets 1 in the left-to-right direction and the arrangement direction (X direction) of the plurality of magnets 1 are +90°, 180°, and -90° respectively. Suppose the leftmost first magnet 1 falls into the groove 211 of the support member 210. At this time, the magnetic pole direction of this magnet 1 is -90°. It is necessary to drive the support member 210 to rotate 180° through the flipping assembly 240 to adjust the magnetic pole direction of this magnet 1 to +90°, and then push the magnet 1 with the adjusted magnetic pole direction into one of the transfer slots 111 of the transfer carrier 110 through the pushing assembly 250. Suppose the leftmost first magnet 1 falls into the groove 211 of the support member 210. At this time, the magnetic pole direction of this magnet 1 is +90°. There is no need to adjust the orientation of the magnet 1 through the flipping assembly 240, and the magnet 1 is directly pushed into one of the transfer slots 111 of the transfer carrier 110 through the pushing assembly 250. Whether the other magnets 1 need to adjust their orientations through the flipping assembly 240 is similar.

[0162] When realizing that the leakage end 2212 selectively faces the blocking member 222 or the support member 210, there are various optional implementation methods. Two implementation methods are exemplarily given below.

[0163] The first implementation method for the leakage end 2212 to selectively face the blocking member 222 or the support member 210: Refer to Figures 12 to 15 , the feeding mechanism 200 further includes a movable frame 260 and a side-shifting assembly 270; both the blocking member 222 and the support member 210 are provided on the movable frame 260; the output end 270a of the side-shifting assembly 270 is connected to the movable frame 260 and is used to drive the movable frame 260 to move so that the leakage end 2212 can selectively face the blocking member 222 or the support member 210.

[0164] Among them, the support member 210 is provided on the movable frame 260, and the support member 210 can be indirectly provided on the movable frame 260. As Figure 12 shown, the flipping assembly 240 is provided on the movable frame 260, and the support member 210 is provided on the output end 240a of the flipping assembly 240, so that the support member 210 is indirectly provided on the movable frame 260.

[0165] In this embodiment, the blocking member 222 and the supporting member 210 are arranged side by side in the X direction. The magazine 221 is stationary, and the movable frame 260 is driven by the side-shifting assembly 270 to move in the X direction, so as to drive the blocking member 222 and the supporting member 210 to move synchronously relative to the magazine 221 in the X direction, so that the leakage end 2212 of the magazine 221 is arranged to face the blocking member 222 or the supporting member 210. During the synchronous movement of the blocking member 222 and the supporting member 210 relative to the magazine 221, it is allowed that the leakage end 2212 of the magazine 221 faces a part of the blocking member 222 and a part of the supporting member 210 at the same time. At this time, the leakage end 2212 is partially blocked by the blocking member 222, and the magnet 1 in the magazine 221 still remains in the material trough 2211 and does not fall. Refer to Figure 13 , Figure 18 , only when the leakage end 2212 of the magazine 221 and the supporting member 210 are completely arranged to face each other, will a single magnet 1 in the magazine 221 fall from the leakage end 2212 into the groove 211 of the supporting member 210.

[0166] The second implementation method for the leakage end 2212 to selectively face the blocking member 222 or the supporting member 210: Refer to Figure 19 , the feeding mechanism 200 further includes a movable frame 260 and a side-shifting assembly 270; the magazine 221 is arranged on the movable frame 260; the output end of the side-shifting assembly 270 is connected to the movable frame 260 and is used to drive the movable frame 260 to move, so that the leakage end 2212 can be selectively arranged to face the blocking member 222 or the supporting member 210.

[0167] In this embodiment, the blocking member 222 and the supporting member 210 arranged side by side in the X direction are stationary, and the movable frame 260 and the magazine 221 are driven by the side-shifting assembly 270 to move in the X direction, so that the leakage end 2212 of the magazine 221 is arranged to face the blocking member 222 or the supporting member 210. During the movement of the magazine 221 relative to the blocking member 222 and the supporting member 210, it is allowed that the leakage end 2212 of the magazine 221 faces a part of the blocking member 222 and a part of the supporting member 210 at the same time. At this time, the leakage end 2212 is partially blocked by the blocking member 222, and the magnet 1 in the magazine 221 still remains in the material trough 2211 and does not fall. Only when the leakage end 2212 of the magazine 221 and the supporting member 210 are completely arranged to face each other, will a single magnet 1 in the magazine 221 fall from the leakage end 2212 into the groove 211 of the supporting member 210.

[0168] In the above two implementation methods, the movable frame 260 can be set in a plate shape or other shapes, as long as it can carry related components (such as the flipping assembly 240, the pushing assembly 250, etc.). The side-shifting assembly 270 can be various linear driving modules that can output linear displacement, such as air cylinders, electric cylinders, etc.

[0169] When setting the side-shifting component 270 and the pushing component 250, refer to Figure 12 and Figure 15 . The moving direction (X direction) of the output end 270a of the side-shifting component 270 is perpendicular to the moving direction (Y direction) of the output end of the pushing component 250 (i.e., the first push rod 252 mentioned later). The side-shifting component 270 is used to drive the movable frame 260 and the predetermined components on the movable frame 260 to move in the X direction, and the pushing component 250 is used to push the magnet 1 in the groove 211 of the support member 210 in the Y direction. The above two directions are arranged perpendicular to each other, which is convenient for the arrangement of related components such as the side-shifting component 270 and the pushing component 250.

[0170] When setting the magazine 221 and the blocking member 222, refer to Figure 14 and Figure 15 . The material groove 2211 of the magazine 221 extends in the vertical direction (Z direction) and is used to accommodate the magnets 1 arranged in a column in the vertical direction. The blocking member 222 has a blocking surface 222a perpendicular to the vertical direction. This way is convenient for the magnets 1 in the material groove 2211 to move downward under the action of gravity. When the leakage end 2212 of the material groove 2211 faces the groove 211 of the support member 210, a single magnet 1 at the leakage end 2212 can fall into the groove 211. The material groove 2211 extends in the vertical direction, and the magazine 221 can be arranged to extend in the vertical direction, and the magazine 221 occupies a small space. The material groove 2211 can have an open end 2213 opposite to the leakage end 2212, and the material groove 2211 is easy to process.

[0171] In order to facilitate the assembly of the side-shifting component 270 and the movable frame 260, in some embodiments, refer to Figure 12 and Figure 15 . The feeding mechanism 200 further includes a first base 280. The side-shifting component 270 is installed on the first base 280, and the movable frame 260 is slidably installed on the first base 280. The movable frame 260 and the first base 280 are connected by a linear guide rail slider assembly 290.

[0172] In this embodiment, both the side-shifting component 270 and the movable frame 260 can be installed on the first base 280. Predetermined components (such as the flipping component 240, the pushing component 250, etc.) can be installed on the movable frame 260. The support member 210 is arranged at the output end 240a of the flipping component 240. The overall structure is easy to assemble, and the support member 210 is arranged at a predetermined height position. The linear guide rail slider assembly 290 can enable the movable frame 260 to be stably slidably installed on the first base 280. The first base 280 can be assembled by multiple plate members or other structural forms.

[0173] Exemplarily, refer to Figure 12 and Figure 15, the movable frame 260 is slidably mounted on the top of the first base 280. A linear guide slider assembly 290 is provided between the movable frame 260 and the first base 280. The linear guide slider assembly 290 may include a linear guide 291 and a slider 292. The linear guide 291 may be fixed on the first base 280, and the slider 292 may be fixed on the movable frame 260. The slider 292 is slidably connected to the linear guide 291, realizing the sliding mounting of the movable frame 260 on the first base 280. The side shift assembly 270 is mounted on the top of the first base 280. The output end 270a of the side shift assembly 270 and the movable frame 260 may be connected by a connecting member 271. The flipping assembly 240, the pushing assembly 250 and the blocking member 222 may be provided on the top surface of the movable frame 260. The material bin 221 may be fixed on the first base 280 through a bracket 223.

[0174] When setting the magnetic pole detection member 230, the magnetic pole detection member 230 may be a Hall magnetic pole detection member. The magnetic field intensity and magnetic pole direction of the magnet 1 on the support member 210 can be detected by the Hall magnetic pole detection member. The magnetic pole detection member 230 may be fixed in the slot of the support member 210.

[0175] In application, the magnetic pole detection member 230 and the flipping assembly 240 may be electrically connected to the controller. The detection signal of the magnetic pole detection member 230 is fed back to the controller. Based on the predetermined magnetic pole direction of the magnet 1 and the detection signal of the magnetic pole detection member 230, the controller can obtain the rotation angle required for the output end 240a of the flipping assembly 240. The flipping assembly 240 receives the working instruction of the controller to rotate the output end 240a of the flipping assembly 240 by a predetermined angle, so that the magnet 1 reaches the predetermined magnetic pole direction.

[0176] When assembling the support member 210, the flipping assembly 240 and the pushing assembly 250, there are various optional implementation manners. Two implementation manners are exemplarily given below.

The control motor can also adjust the orientation of the magnet 1, preparing for the pushing component 250 to push the magnet 1 with a predetermined magnetic pole direction onto the transfer carrier 110. The first push rod 252 in the pushing component 250 passes through the hollow output shaft 241 and is disposed opposite to the groove 211.

The plurality of second guiding grooves 312 communicate with the assembling grooves 311, and the plurality of second push rods 322 and the plurality of second guiding grooves 312 are correspondingly arranged.

[0196] When the transfer carrier 110 is located at the assembly position 110b, a plurality of transfer slots 111 of the transfer carrier 110 and a plurality of second guiding slots 312 of the assembly carrier 310 can be arranged in one-to-one correspondence. During the process of the second linear driving member 321 driving the second push rod 322, first, the second push rod 322 enters the transfer slot 111 of the transfer carrier 110 to push the magnet 1 in the transfer slot 111 into the second guiding slot 312 in the assembly carrier 310, and then the second push rod 322 pushes the magnet 1 in the second guiding slot 312 into the assembly slot 311 of the assembly carrier 310. The second guiding slot 312 plays a guiding role for the magnet 1, so that the magnet 1 entering the assembly slot 311 will not rotate and tilt.

[0197] In order to make the height position of the assembly carrier 310 adjustable, in some embodiments, refer to Figure 23 、 Figure 25 The assembly carrier 310 is arranged on the third height adjusting member 314, and the third height adjusting member 314 is used to adjust the height position of the assembly carrier 310 so that the assembly slot 311 and the transfer slot 111 are flush.

[0198] The assembly carrier 310 is arranged on the third height adjusting member 314. By adjusting the height position of the assembly carrier 310 through the third height adjusting member 314, the transfer slot 111 of the transfer carrier 110 and the assembly slot 311 of the assembly carrier 310 are at the same height, which is convenient for the magnet 1 in the transfer carrier 110 to smoothly enter the assembly carrier 310. The third height adjusting member 314 can be a lead screw slide table or the like.

[0199] When setting the pressing assembly 330, refer to Figure 23 、 Figure 25 The pressing assembly 330 includes a third linear driving member 331, a limiting member 332, a fourth linear driving member 333 and a third push rod 334. Combining Figure 26 、 Figure 27 The assembly carrier 310 has a third guiding slot 313 communicating with the assembly slot 311. The output end 331a of the third linear driving member 331 is connected to the limiting member 332, and the third linear driving member 331 is used to drive the limiting member 332 to move and abut against one end of the magnet 1 in the assembly slot 311 along the predetermined arrangement direction (X direction). The output end 333a of the fourth linear driving member 333 is connected to the third push rod 334, and the third push rod 334 is slidably installed in the third guiding slot 313. The fourth linear driving member 333 is used to drive the third push rod 334 to move and abut against the other end of the magnet 1 in the assembly slot 311 along the predetermined arrangement direction (X direction).

[0200] Such as Figure 23 、 Figure 28As shown in the figure, when it is necessary to press multiple magnets 1 in the assembly carrier 310 along the arrangement direction of the magnets 1 (X direction), the third linear drive 331 drives the limiting member 332 to move, so that the limiting member 332 abuts against one end magnet 1. The fourth linear drive 333 drives the third push rod 334 to move in the third guide groove 313 of the assembly carrier 310. The third push rod 334 pushes the other end magnet 1, so that the multiple magnets 1 in the assembly groove 311 are pressed by the limiting member 332 and the third push rod 334, reducing the distance between the multiple magnets 1 and preparing for the connection mechanism 400 to connect the multiple magnets 1. As Figure 29 shown, after the connection mechanism 400 completes the assembly of the multiple magnets 1 in the assembly groove 311, the fourth linear drive 333 is also used to drive the third push rod 334 to move so as to push out the assembled magnet array from the assembly groove 311.

[0201] Exemplarily, as Figure 4 shown in (a) of the figure, multiple magnets 1 are located in the assembly groove 311 of the assembly carrier 310. The limiting member 332 abuts against the right end face of the rightmost magnet 1, and the third push rod 334 abuts against the left end face of the leftmost magnet 1, so that the multiple magnets 1 are pressed along the arrangement direction (X direction).

[0202] The third linear drive 331 and the fourth linear drive 333 can be various linear drive modules that can output linear displacement, such as cylinders, electric cylinders, etc. Refer to Figure 23 . In application, a pressure sensor 335 and a displacement sensor 336 can be arranged on the third push rod 334. Both the pressure sensor 335 and the displacement sensor 336 are electrically connected to the controller. The pressure sensor 335 can detect the pressure of the third push rod 334, and the displacement sensor 336 can detect the displacement of the third push rod 334, feeding back the pressure signal and the displacement signal to the controller, and controlling the third linear drive 331 to work through the controller so that the third push rod 334 reaches the predetermined pressure and displacement.

[0203] In order to align the third push rod 334 with the third guide groove 313, in some embodiments, refer to Figure 23 、 Figure 26 . On the basis of setting the third height adjusting member 314, the third height adjusting member 314 is arranged on the second lateral adjusting member 314a. The second lateral adjusting member 314a is used to adjust the position of the assembly carrier 310 along the Y direction so as to align the third push rod 334 with the third guide groove 313 of the assembly carrier 310. The second lateral adjusting member 314a can be in the form of a lead screw slide table, etc. The combination of the second lateral adjusting member 314a and the third height adjusting member 314 can adopt a two-dimensional slide table that can output displacements in the Y direction and the Z direction.

[0204] When manufacturing the assembly carrier 310, there are various optional implementation methods. Two implementation methods are exemplarily given below.

[0205] The first implementation method of the assembly carrier 310 is shown in Figure 26 , Figure 30 , Figure 31 . The assembly carrier 310 may include a first structural member 316 and a second structural member 317. On the same side of the first structural member 316, there are a second groove 3161 corresponding to the assembly groove 311, a third groove 3162 corresponding to the second guiding groove 312, a fourth groove 3163 corresponding to the third guiding groove 313, and a processing window 315. The first structural member 316 is mounted on the second structural member 317, and the first structural member 316 and the second structural member 317 together enclose the assembly groove 311, the second guiding groove 312, and the third guiding groove 313. The second structural member 317 may have a positioning groove 3171 to facilitate the positioning and installation of the first structural member 316 at the positioning groove 3171. The first structural member 316 and the second structural member 317 may be arranged as plate bodies. The first structural member 316 and the second structural member 317 may be connected by fasteners or other means. The first structural member 316 and the second structural member 317 may be made of non-ferromagnetic materials such as copper, aluminum, or plastic, facilitating the pushing of the magnet 1 inside the assembly carrier 310 by the second push rod 322 or the third push rod 334.

[0206] In some embodiments, as shown in Figure 26 , Figure 27 , the assembly carrier 310 may further include a magnetic attraction part 318 made of ferromagnetic materials (such as iron, steel, etc.). The magnetic attraction part 318 and the second guiding groove 312 are arranged opposite to each other. The magnetic attraction part 318 is used for magnetically attracting the magnet 1 in the second guiding groove 312 to make the magnet 1 located at a position opposite to the third guiding groove 313, preparing for the third push rod 334 to push the magnet 1 through the third guiding groove 313 towards the processing window 315. The magnetic attraction part 318 may be installed in the groove positions of the first structural member 316 and the second structural member 317.

[0207] The second implementation method of the assembly carrier 310: The assembly carrier 310 may be a single structural member, and the assembly groove 311, the second guiding groove 312, the third guiding groove 313, and the processing window 315 are all provided on this structural member.

[0208] When arranging the third linear driving member 331 and the fourth linear driving member 333, there are various optional implementation methods. Two implementation methods are exemplarily given below.

[0209] The first arrangement method of the third linear driving member 331 and the fourth linear driving member 333: As shown in Figure 23 , Figure 25 , the moving direction (Z direction) of the output end 331a of the third linear driving member 331 is perpendicular to the moving direction (X direction) of the output end of the fourth linear driving member 333;

[0210] The second arrangement of the third linear drive member 331 and the fourth linear drive member 333: the moving direction (X direction) of the output end 331a of the third linear drive member 331 and the moving direction (X direction) of the output end 333a of the fourth linear drive member 333 are parallel.

[0211] Both arrangements can realize the driving of the limiting member 332 and the third push rod 334 , and the limiting member 332 and the third push rod 334 can compress the multiple magnets 1 in the assembly carrier 310 along the arrangement direction (X direction) of the magnets 1 .

[0212] In order to facilitate the installation of components such as the assembly carrier 310, in some embodiments, refer to Figure 21 , Figure 23 The third height adjustment member 314, the third linear driving member 331, and the fourth linear driving member 333 can be installed on the second base 350. The second base 350 can be assembled from a plurality of plates or in other structural forms.

[0213] In order to facilitate the connection of the connection mechanism 400 to the plurality of magnets 1, in some embodiments, refer to Figure 6 , Figure 32 The connection mechanism 400 includes a connection assembly 410, combined with Figure 26 , Figure 27 The assembly carrier 310 has a processing window 315 connected to the assembly groove 311, and the connecting component 410 and the processing window 315 are arranged facing each other.

[0214] A processing window 315 is provided on the assembly carrier 310 , and when the pressing assembly 330 presses the multiple magnets 1 in the assembly carrier 310 along the arrangement direction (X direction), the connecting assembly 410 in the connecting mechanism 400 performs connection processing on the multiple magnets 1 .

[0215] There are multiple optional implementations when setting the connection component 410, and two implementations are given as examples below.

[0216] The first implementation of the connection component 410: Figure 6 , Figure 32 The connecting component 410 includes a laser head 411 and a galvanometer 412 which are arranged opposite to each other. The galvanometer 412 and the processing window 315 are arranged opposite to each other. The galvanometer 412 is used to irradiate the laser beam 413 generated by the laser head 411 to the gap between adjacent magnets 1 in the assembly groove 311.

[0217] In this embodiment, laser welding is used to connect multiple magnets 1. The laser head 411 generates a laser beam 413 with a high energy density. The galvanometer 412 swings to reflect the laser beam 413 towards the processing window 315 and irradiate it near the gap of the magnet 1, melting a part of the magnet 1 to form a molten pool, thus realizing the reliable connection of adjacent magnets 1.

[0218] The implementation method of the second connecting component 410: The connecting component 410 includes a dispensing head, and the dispensing head is used to dispense glue onto the magnet 1 in the assembly groove 311.

[0219] In this embodiment, dispensing is used to connect multiple magnets 1. The glue output by the dispensing head enters near the gap of the magnet 1, and after the glue solidifies, the connection of adjacent magnets 1 is realized.

[0220] In some embodiments, the connecting component 410 further includes a hot pressing head, and the hot pressing head is used to press and heat multiple magnets 1. The hot pressing head is connected to a heating element, and the heat generated by the heating element is conducted to the glue through the hot pressing head. By pressing and heating the magnet 1 with the hot pressing head, the solidification of the glue in the gap of the magnet 1 is accelerated, realizing the reliable connection of adjacent magnets 1.

[0221] To adjust the height position of the connecting component 410, in some embodiments, refer to Figure 6 、 Figure 32 , the connecting mechanism 400 further includes a fifth linear driving member 420, and the fifth linear driving member 420 is used to adjust the height position of the connecting component 410. The height position of the connecting component 410 can be adjusted by the fifth linear driving member 420, so that the connecting component 410 approaches or moves away from multiple magnets 1 on the assembly carrier 310, realizing the connection processing of multiple magnets 1. The fifth linear driving member 420 can be various driving modules that can output linear displacement, such as an electric cylinder, etc.

[0222] To obtain the processing condition of the magnet 1 in the assembly carrier 310, in some embodiments, refer to Figure 6 、 Figure 28 、 Figure 32 , the connecting mechanism 400 further includes a camera module 430. The camera module 430 is arranged in parallel with the connecting component 410, and the camera module 430 is used to photograph the magnet 1 in the assembly groove 311. By obtaining the processing condition of the magnet 1 in the assembly carrier 310 through the camera module 430, it is beneficial for the connecting component 410 to perform automated processing. The camera module 430 can be arranged at the output end 420a of the fifth linear driving member 420 and move along with the connecting mechanism 400.

[0223] In some embodiments, refer to Figure 4 、 Figure 6 、 Figure 7, when the number of the feeding mechanisms 200 is multiple, the multiple feeding mechanisms 200 include a first feeding mechanism 200a and a second feeding mechanism 200b, and the first magnet 1a provided by the first feeding mechanism 200a and the second magnet 1b provided by the second feeding mechanism 200b are different in cross-sectional area or magnetic pole direction. At least two feeding mechanisms 200 are configured such that the magnets 1 provided by them are different in cross-sectional area or magnetic pole direction.

[0224] By configuring multiple feeding mechanisms 200, the multiple feeding mechanisms 200 respectively provide magnets 1 with a predetermined cross-sectional area and a predetermined magnetic pole direction. The first magnet 1a provided by the first feeding mechanism 200a and the second magnet 1b provided by the second feeding mechanism 200b are different in cross-sectional area or magnetic pole direction. The transfer carrier 110 moves to different feeding positions 110a, and multiple magnets 1 can be quickly arranged on the transfer carrier 110. The magnetic pole directions of the respective magnets 1 are set as required, and the arrangement efficiency of the magnets 1 is high.

[0225] Exemplarily, refer to Figure 4 , the magnet array includes first magnets 1a and second magnets 1b arranged in an interleaved manner. Both the first magnets 1a and the second magnets 1b are cuboids, and the cross-sectional area of the first magnet 1a is larger than that of the second magnet 1b. The cross-section of the magnet 1 is perpendicular to the Y direction. The magnetic pole direction of the first magnet 1a is perpendicular to the arrangement direction (X direction) of the multiple magnets 1, and the magnetic pole directions of two adjacent first magnets 1a are opposite. The magnetic pole direction of the second magnet 1b is parallel to the arrangement direction (X direction) of the multiple magnets 1. The arrow on the magnet 1 indicates the magnetic pole direction of the magnet 1.

[0226] When assembling the magnet array having the first magnets 1a and the second magnets 1b, feeding mechanisms 200 with the same number as the first magnets 1a and the second magnets 1b can be configured, and each feeding mechanism 200 respectively provides a magnet 1 at a different arrangement position in the magnet array. For example, if the magnet array includes two first magnets 1a and one second magnet 1b, two feeding mechanisms 200 can be configured to provide the first magnets 1a with different magnetic pole directions, and one feeding mechanism 200 can be configured to provide the second magnet 1b with a predetermined magnetic pole direction.

[0227] When assembling the magnet array having the first magnets 1a and the second magnets 1b, two feeding mechanisms 200 can be configured, one of the feeding mechanisms 200 provides the first magnets 1a with different magnetic pole directions, and the other feeding mechanism 200 provides the second magnet 1b with a predetermined magnetic pole direction.

[0228] It can be understood that the magnets in the magnet array can also have other arrangement ways, and the number of the feeding mechanisms 200 is set as required, which will not be elaborated here.

[0229] To enable the magnet assembly device 1000 to work for a long time, in some embodiments, refer to Figure 6 , Figure 7 , multiple feeding mechanisms 200 can be configured as backup mechanisms. When some feeding mechanisms 200 need to be maintained or repaired, the backup feeding mechanisms 200 replace them to work, enabling the magnet assembly device 1000 to work reliably for a long time.

[0230] In some embodiments, refer to Figure 33 , Figure 34 , when the number of feeding mechanisms 200 is one, the feeding mechanism 200 can provide magnets 1 with the same cross-sectional area and different magnetic pole directions.

[0231] The magnet array includes multiple magnets 1 with the same cross-sectional area. The magnetic pole directions of the multiple magnets 1 are perpendicular or parallel to the arrangement direction of the magnets 1. The cross-section of the magnet 1 is perpendicular to the Y direction. Each time, a feeding mechanism 200 provides a magnet 1 with a predetermined magnetic pole direction to one transfer slot 111 in the transfer carrier 110 until the multiple transfer slots 111 of the transfer carrier 110 are filled with magnets 1 with a predetermined magnetic pole direction, achieving rough positioning of the multiple magnets 1, as shown in (a) of Figure 34 . Fine positioning of the multiple magnets 1 is achieved through the assembly mechanism 300, and finally, connection of the multiple magnets 1 is achieved through the connection mechanism 400, as shown in (b) of Figure 34 .

[0232] In the case where the transfer mechanism 100 is arranged in a ring shape, refer to Figure 35 , the output end 120a of the transmission component 120 can output rotational motion, and one or more feeding positions 110a and assembly positions 110b are arranged in a ring shape. The assembly mechanism 300 and the feeding mechanism 200 can be arranged in a ring shape. The transmission component 120 drives the transfer carrier 110 to flow between the feeding position 110a and the assembly position 110b.

[0233] Among them, the transmission component 120 can be various drive modules that can output rotational motion, such as a combination of a control motor and a turntable. The transmission component 120 can be provided with a displacement sensor to detect whether the transfer carrier 110 moves to a predetermined position, such as the feeding position 110a or the assembly position 110b.

[0234] Exemplarily, refer to Figure 35 , multiple feeding mechanisms 200 are arranged at intervals along the circumferential direction on the outer side of the ring. The feeding mechanism 200 provides magnets 1 with a predetermined magnetic pole direction and cross-sectional area. The assembly carrier 310 and the pressing component 330 in the assembly mechanism 300 are arranged on one side of the transmission component 120, and the transfer component 320 in the assembly mechanism 300 is arranged on the other side of the transmission component 120.

[0235] Refer to Figure 6 、 Figure 36 The embodiment of the present application provides a magnet assembly process, which applies the above-mentioned magnet assembly device 1000. The magnet assembly process includes:

[0236] Step 510: As shown in Figure 16 , place the transfer carrier 110 at the feeding position 110a. The feeding mechanism 200 provides the magnet 1 with a predetermined magnetic pole direction to the transfer groove 111 of the transfer carrier 110, so that a plurality of transfer grooves 111 correspondingly accommodate and position a plurality of magnets 1;

[0237] Step 520: As shown in Figure 27 , place the transfer carrier 110 at the assembly position 110b. The transfer component 320 transfers the magnets 1 in a plurality of transfer grooves 111 to the assembly grooves 311 of the assembly carrier 310; as shown in Figure 28 , the pressing component 330 presses the plurality of magnets 1 in the assembly groove 311 along the predetermined arrangement direction;

[0238] Step 530: As shown in Figure 4 , connect the plurality of magnets 1 in the assembly groove 311 through the connection mechanism 400.

[0239] In the magnet assembly process provided by the embodiment of the present application, when the transfer carrier 110 is located at the feeding position 110a, the feeding mechanism 200 corresponding to the feeding position 110a can provide the magnet 1 with a predetermined magnetic pole direction to the transfer groove 111 of the transfer carrier 110, and accommodate and position the magnet 1 in the transfer groove 111. The transfer carrier 110 is used to reduce the distance between the magnets 1, realizing the rough positioning of the plurality of magnets 1 on the transfer carrier 110. The magnet 1 after rough positioning lacks space rotation and inclination, preventing the magnetic pole direction of the magnet 1 from being disordered without external force constraint. When a predetermined number of magnets 1 are installed in the transfer groove 111 of the transfer carrier 110, the transfer carrier 110 is placed at the assembly position 110b. The transfer component 320 in the assembly mechanism 300 transfers the plurality of magnets 1 on the transfer carrier 110 to the assembly grooves 311 of the assembly carrier 310, and presses the plurality of magnets 1 in the assembly groove 311 along the arrangement direction through the pressing component 330 to realize the fine positioning of the plurality of magnets 1. The plurality of magnets 1 in the assembly groove 311 are connected through the connection mechanism 400. This magnet assembly process can realize the assembly of a Halbach array or a similar magnet array with the number of magnets 1 greater than or equal to 3, is applicable to the assembly of large-sized magnets and small-sized magnets, enables each magnet 1 to maintain a predetermined magnetic pole direction, has good manufacturability, good assembly consistency, good reliability, and high assembly efficiency.

Any changes or substitutions within the technical scope disclosed in this application should be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claimed rights.
