[0002] In the field of direct-drive linear motion, a primary permanent magnet vernier linear motor integrates the characteristics of a permanent magnet motor and a linear motor, has high thrust and high efficiency, and has the advantages of low cost in the long-stroke field because the permanent magnet and the winding are integrated in the primary. The primary permanent magnet vernier linear motor is currently widely used in the fields of numerical control machine tools, 3C product manufacturing equipment, high-speed logistics systems, liquid crystal panel transportation systems, and cordless elevators.

[0003] With the design and research of the topological structure of the primary permanent magnet vernier linear motor, a U-shaped Halbach magnetic concentration structure appears. The magnetic concentration unit of the U-shaped Halbach magnetic concentration structure is composed of five permanent magnets which form a U shape. The magnetization directions of the five permanent magnets are different, but they are all concentrated at the center point of the U-shaped structure. In the process of linear motor machining and assembly, the assembly of the permanent magnet is extremely important and determines the electromagnetic performance of the motor. Therefore, it is necessary to ensure the assembly precision of the permanent magnet, reduce the surface wear of the permanent magnet, and reduce the generation of waste products. Because the magnetization directions of the five permanent magnets are different, repulsion will be generated between the permanent magnets during assembly, which reduces the production efficiency and is not conducive to widespread application.

[0087] Specifically, please refer to Figure 5 again, the first assembling mechanism 200 includes the first positioning component 210, the first fixing component 220 and two first prosthesis structures 211, the first positioning component 210 and the first fixing component 220 are detachably fixedly connected and enclose a first positioning space therebetween, and the one core unit can be correspondingly arranged in the first positioning space, and the first fixing component 220 can be fixedly connected with the core in a detachable manner to fix the core in the first positioning space; the first prosthesis structure 211 is fixedly arranged on the first positioning component 210 and located inside the first positioning space, and the two first prosthesis structures 211 correspond to the two mounting grooves 110, respectively, the profile structure of each first prosthesis structure 211 is same as the profile structure of the second assembling space 102, the third assembling space 103, the fifth assembling space 105 and the sixth assembling space 106 as a whole, and two first windows (or referred to as first channels, the same below) 212 are further formed in the first positioning component 210, the first windows 212 are in communication with the first positioning space, and the two first windows 212 correspond to the two mounting grooves 110, respectively.

[0088] Specifically, the first positioning component 210 can be a ring-shaped member, and the first positioning component 210 and the first fixing component 220 are fixedly connected to form a ring-shaped structure. For example, the first fixing component 220 can be fixedly connected to the iron core through a threaded connecting member or the like, and the first fixing component 220 and the first positioning component 210 can also be connected and fixed through a threaded connecting member.

[0089] Specifically, the first positioning component 210 has a first working surface, the first prosthetic structure 211 is arranged on the first working surface, and the first window 212 is in communication with the first working surface. When the iron core unit is fixed in the first positioning space, the end faces of the first core tooth 121, the second core tooth 122, and the third core tooth 123 are flush with and abut the first working surface. The first prosthetic structure 211 is arranged in the mounting groove 110 and occupies or fills the second assembly space 102, the third assembly space 103, the fifth assembly space 105, and the sixth assembly space 106. The first window 212 corresponds to and communicates with the first assembly space 101 and the fourth assembly space 104 along the first direction, and the first magnetic steel 601 can enter the first assembly space 101 from the first window 212.

[0090] Specifically, the first prosthetic structure 211 can be a boss structure arranged on the first positioning component 210, which can be integrally arranged with the first positioning component 210.

The first magnetic steel 601 can slide into the first assembly space along the first guide surface, and the first magnetic steel 601 can be kept in a fixed posture when entering the mounting groove, thereby improving the assembly precision. More specifically, the first guide surface can be a wedge surface, and the inner contour of the first window can be matched with the first magnetic steel 601.

When the first assembly mechanism is combined with the iron core unit, the first limiting structure 213 is located on the side of the third core tooth 123 facing away from an adjacent mounting groove 100. In the second direction, the first limiting structure 213 abuts against the third core tooth 123 to facilitate the positioning and fixing of the assembly fixture, ensuring that there is no relative movement between the first positioning component and the iron core, thereby improving the installation accuracy of the magnet.

[0116] Embodiment 2

[0117] An assembly method of a U-shaped magnetic concentration structure, comprising the steps of: fixing a first magnetic steel 601, a second magnetic steel 602, a third magnetic steel 603, a fourth magnetic steel 604, a fifth ferromagnetic body 605 and a sixth magnetic steel 606 in a first assembly space 101, a second assembly space 102, a third assembly space 103, a fourth assembly space 104, a fifth assembly space 105 and a sixth assembly space 106 of an installation groove 110 respectively, so as to form a U-shaped magnetic concentration structure. Figure 1 as shown.

[0118] Specifically, please refer to Figure 11 The assembly method of the U-shaped magnetic concentration structure in the embodiment is implemented by using the assembly tool of the U-shaped magnetic concentration structure in Embodiment 1, and the assembly method of the U-shaped magnetic concentration structure specifically comprises:

[0119] 1) First, fix the first magnetic steel 601 with a circular arc surface in the first assembly space 101 by using the first assembly mechanism 200, and then remove the first assembly mechanism 200.

[0120] Specifically, the first assembling mechanism 200 is first fixed with the core 100, the first false body structure 211 in the first assembling mechanism 200 is arranged in the mounting groove 110 and fills the second assembling space 102, the third assembling space 103, the fifth assembling space 105 and the sixth assembling space 106, the first magnetic steel 601 is introduced into the first assembling space 101 through the first window 212 of the first assembling mechanism 200 and is fixedly combined with the inner wall of the mounting groove 110.

[0121] Specifically, the first magnetic steel 601 can be fixedly combined with the inner wall of the mounting groove 110 in a bonding manner.

[0122] It should be noted that, please refer to Figures 12-14 In order to reduce the repulsive force generated in too many magnetic steels, the first magnetic steel is assembled first, only the attractive force to the core is generated in the assembling process, and no repulsive force is generated, and the assembling is simple.

[0123] 2) The third magnetic steel 603 with a circular arc surface is fixed in the third assembling space 103 by the second assembling mechanism 300, and then the second assembling mechanism 300 is removed.

[0124] Specifically, the second assembling mechanism 300 is first fixed with the core 100, the second false body structure 311 in the second assembling mechanism 300 is arranged in the mounting groove 110 and fills the second assembling space 102, the fourth assembling space 104 and the fifth assembling space 105, the third magnetic steel 603 is introduced into the third assembling space 103 through the second window 312 of the second assembling mechanism 300 and is fixedly combined with the inner wall of the mounting groove 110.

[0125] Specifically, the third magnetic steel 603 can be fixedly combined with the inner wall of the mounting groove 110 in a bonding manner.

[0126] It should be noted that, from Figure 12 It can be seen that, in the assembling process of the third magnetic steel, the first magnetic steel does not generate repulsive force to the third magnetic steel, the third magnetic steel only generates attractive force to the core and does not generate repulsive force, and the assembling is simple.

[0127] 3) The second magnetic steel 602 in a rectangular shape is fixed in the second assembling space 102 by the third assembling mechanism 400.

[0128] Specifically, the third assembly mechanism 400 is first fixed with the core 100, the third prosthetic structure 411 in the third assembly mechanism 400 is arranged in the mounting groove 110 and fills the fourth assembly space 104 and the sixth assembly space 105 (it can be understood that the third prosthetic structure includes two spaced apart boss structures), at the same time, the third prosthetic structure 411 also abuts and presses the first magnetic steel 601 and the third magnetic steel 603 in the first direction, the second magnetic steel 602 is guided into the second assembly space 102 from the third window 412 of the third assembly mechanism 400 and is fixedly combined with the inner wall of the mounting groove 110, and the first fastening part 430 is fixed with the third positioning part 410, and the first fastening boss 431 of the first fastening part 430 passes through the third window 412 and abuts and presses on the second magnetic steel 602.

[0129] Specifically, the second magnetic steel 602 can be fixedly combined with the inner wall of the mounting groove 110 in a bonding manner.

[0130] It should be noted that, in the process of assembling the third magnetic steel, the rectangular second magnetic steel located between the first magnetic steel and the third magnetic steel is assembled for the third time, which can ensure that the horizontal position is consistent when the next layer of magnetic steel is assembled, but the first magnetic steel and the third magnetic steel on both sides will generate repulsive force on it, and the first fastening part is used to fix the first magnetic steel, the second magnetic steel and the third magnetic steel. Figure 13 It can be seen from the simulated force analysis diagram that, in the process of installing the rectangular second magnetic steel in the middle, the force changes from attraction to repulsion from the distal end to the proximal end (close to the bottom of the mounting groove), so in order to prevent the magnetic steel from being repelled by the repulsive force before the bonding material solidifies, the magnetic steel needs to be pre-tightened to ensure that it will not be repelled by the repulsive force during the bonding process, so the first fastening part is used to additionally fix the first magnetic steel, the second magnetic steel and the third magnetic steel, mainly to fix the second magnetic steel, and then the first fastening part 430 is removed after the second magnetic steel is fixed.

[0131] 4) The rectangular fifth ferromagnetic body 605 is fixed in the fifth assembly space 105 by the third assembly mechanism 400, and then the third assembly mechanism 400 is removed.

[0132] Specifically, since the position of the fifth ferromagnetic body 605 in the first direction corresponds to that of the second magnetic steel 602, the same assembly mechanism is directly used for assembly, and the specific process can be: the fifth ferromagnetic body 605 is guided into the fifth assembly space 102 from the third window 412 of the third assembly mechanism 400, since the fifth ferromagnetic body 605 can be attracted by the magnetic steel, the first fastening part 430 is not needed to fix it, and the fifth ferromagnetic body 605 can be directly attracted and fixed on the second magnetic steel 602. For example, the material of the fifth ferromagnetic body can be silicon steel or the like.

[0133] 5) Fourth assembly mechanism 500 fixes rectangular fourth magnetic steel 604 and sixth magnetic steel 606 in fourth assembly space 104 and sixth assembly space 106 respectively.

[0134] Specifically, fourth assembly mechanism 500 is fixed with iron core 100 first, fourth working surface of fourth assembly mechanism 500 is flush with end surface of core tooth of iron core, and the two are adhered, so two third limiting structures 513 are adopted to abut against two core teeth in the second direction, so as to avoid relative movement between fourth assembly mechanism 500 and iron core, thereby ensuring the assembly precision.

[0135] Fourth magnetic steel 604 is introduced into fourth assembly space 104 through fourth window 512 of fourth assembly mechanism 500 and is fixed and combined with the inner wall of mounting groove 110, sixth magnetic steel 606 is introduced into sixth assembly space 106 through fifth window 514 and is fixed and combined with the inner wall of mounting groove 110, second fastening part 530 is fixed with fourth positioning part 510, second fastening boss 531 of second fastening part 530 abuts against fourth magnetic steel 604 in fourth assembly space 104, third fastening boss 532 abuts against sixth magnetic steel 606 in sixth assembly space 106, and fourth assembly mechanism 500 is removed after fourth magnetic steel 604 and sixth magnetic steel 606 are fixed.

[0136] Specifically, fourth magnetic steel 604 and sixth magnetic steel 606 can be fixed and combined with the inner wall of mounting groove 110 by means of adhesion.

[0137] It should be noted that repulsive force is generated on fourth magnetic steel and sixth magnetic steel during assembly of fourth magnetic steel and sixth magnetic steel, and Figure 14 It can be found from the force simulation diagram shown in the figure that during installation of fourth magnetic steel and sixth magnetic steel, the force changes from attraction between magnetic steels to repulsion from the distal end to the proximal end (the proximal end is the end close to the bottom of the mounting groove), so the fourth magnetic steel and the sixth magnetic steel need to be fixed for a short time before the adhesive material solidifies, and the second fastening part 530 can realize the fixation of the fourth magnetic steel and the sixth magnetic steel to avoid relative movement between the magnetic steels.

[0138] Figure 12 、 Figure 13 、 Figure 14 In the X-axis direction, a positive number represents repulsion to the magnetic steel, and a negative number represents attraction to the magnetic steel (i.e. a positive number corresponds to a positive force in the second direction, and a negative number is the opposite); in the Y-axis direction, a positive number represents attraction to the magnetic steel, and a negative number represents repulsion to the magnetic steel (i.e. a positive number corresponds to a negative force in the first direction, and a negative number is the opposite).

[0139] The U-shaped magnetic structure assembling tool and the assembling method can improve the assembling efficiency, ensure the reliability and rate of the assembling, thereby improving the production qualified rate of the linear motor, and the U-shaped magnetic structure assembling tool can position the assembling positions of the plurality of magnetic steels, and can ensure the reliability of the magnetic steel assembling.

[0140] The U-shaped magnetic structure assembling method is more suitable for the repulsive force and attractive force generated in the installation process of the U-shaped Halbach magnetic unit array, has higher assembling efficiency and installation precision, each assembling process has a corresponding tool, reduces the waste rate of the magnetic steel, reduces the wear of the surface of the magnetic steel, thereby improving the batch production efficiency of the primary permanent magnet vernier linear motor, and ensures the electromagnetic performance and service life of the motor.
