Description

TECHNICAL FIELD

[0001] The utility model relates to a jig, especially to an assembling jig of repulsion magnets. BACKGROUND

[0002] It is very difficult to assemble the magnets repelling each other. Taking the Halbach array of magnets as an example, multiple magnets are arranged according to a specific rule, such as the magnetization directions of adjacent magnets having an included angle of 60 degrees or 120 degrees. These magnets are adhered together by magnet adhesive and clamped by a fixing clamp. In this way, the magnetic lines of force are converged on one side of the array, while the magnetic lines of force are weakened on the other side, so that a relatively ideal one-sided magnetic field can be obtained. However, the repulsion between adjacent magnets is relatively large, and the magnets are prone to self-tilting during the curing stage of the adhesive. Therefore, additional time is required to correct the tilted magnets, and the assembly efficiency is relatively low. SUMMARY

DETAILED DESCRIPTION

[0063] The embodiment of the utility model provides a kind of assembly jig of repulsion magnet, can be bonded and assembled to the magnet of one column between adjacent magnet, the assembly jig of this can be fixed to magnet or magnet combination from multiple directions in the stage of glue curing, prevent the phenomenon of magnet self-inversion occurs.This embodiment arranges multiple magnets according to the requirement of Halbach array.

[0064] As Figure 1 , Figure 2As shown, the assembly fixture comprises a base 10, a cover plate 70, two guide rods 60 respectively penetrating through the cover plate 70 and extending into the base 10 at the front and rear sides, a left top block 40 and a right top block 30 connected to the left and right sides of the base 10, and two stop blocks 50 connected to the front and rear sides of the base 10; each stop block 50 is provided with an operating rod 51 and a positioning block 52 for locking the corresponding guide rod 60. The base 10, the cover plate 70, the left top block 40 and the right top block 30 can simultaneously fix the combination of the magnetic attraction gasket 20 and the magnet or magnet combination from multiple directions.

[0065] The base 10 bears the magnetic attraction gasket 20 and a plurality of magnets, and the magnetic attraction gasket 20 is commonly magnetized; the plurality of magnets are sequentially bonded to the magnetic attraction gasket 20 in the direction and order specified in the Halbach array, and are bonded to adjacent magnets until all the magnets are bonded to form the Halbach array. Specifically, among these magnets, one of the intermediate magnets is first bonded to the magnetic attraction gasket 20, and the other magnets are bonded to the left and right sides of the magnetic attraction gasket 20 and the already bonded magnets or magnet combinations in pairs in turn and symmetrically. Since the repulsion between adjacent magnets is large, and the sizes of adjacent magnets are not the same, it is easy to cause the smaller magnet to flip over.

[0066] These magnets can be a plurality of magnetic stones, or a plurality of magnet segments pre-magnetized. Referring to Figure 11 As shown, the following is a schematic description of a Halbach array composed of five magnetic stones, which includes a middle magnetic stone 81, two interval magnetic stones 82 and two outer magnetic stones 83. The middle magnetic stone 81 is located in the middle, the two interval magnetic stones 82 are located on the left and right sides of the middle magnetic stone 81, and the two outer magnetic stones 83 are further located on the left and right sides of the combination of the middle magnetic stone 81 and the two interval magnetic stones 82. The length, width and height of the five magnetic stone combination in this example are about 12.7mm x 8.2mm x 1.5mm. When arranged on the base 10, the length direction of the magnetic stone combination corresponds to the front and rear direction of the base 10. Among them, the middle magnetic stone 81 and the outer magnetic stone 83 are smaller in size, which is manifested as the width of the interval magnetic stone 82 being greater than the width of the middle magnetic stone 81 or the outer magnetic stone 83 adjacent to it (the length and height of the three are the same), causing the middle magnetic stone 81 and the outer magnetic stone 83 (especially the middle magnetic stone 81) to be more prone to tipping over under the action of repulsion. The assembly fixture of the utility model can effectively prevent this situation from occurring. It can be understood that the number, size and arrangement of the above-mentioned magnetic stones are only examples and are not a limitation on the applicable magnet array of the assembly fixture; assuming that there are more number of magnetic stones in the array, they can be further bonded to the left and right sides of the magnetic attraction gasket 20 and the already bonded magnet combination in pairs symmetrically, and during the waiting period for the glue to solidify, the base 10, the cover plate 70, the left top block 40 and the right top block 30 of the assembly fixture are fixed from multiple directions.

[0067] For details, see Figure 1、 Figure 2 、 Figure 5 As shown in the drawings, the top of the base 10 is provided with a first recess 110 in the middle, and the magnetic pad 20 is placed in the first recess 110. The first recess 110 is provided with a plurality of flared portions 111 around the periphery, which facilitates the removal of the magnetic pad 20 embedded in the first recess 110. The bottom of the cover plate 70 is provided with a second recess 72, which can cooperate with the first recess 110 on the top of the base 10. When the first recess 110 and the second recess 72 are opposite to each other, the space between them is used to place the combination of the magnetic pad 20 and the magnet or magnet combination.

[0068] The two corners of the front side of the top of the base 10 are respectively provided with front side corner support portions 102; and a front side middle support portion 101 is provided in the middle of the top of the base 10 on the front side, which is located between and separated from the two front side corner support portions 102, so as to form two front side openings 12 between the front side middle support portion 101 and the two front side corner support portions 102, which are used for dispensing and placing the magnets (such as the middle magnet 81 and the outer magnet 83) on the magnetic pad 20. The bottom surface of the two front side openings 12 is lower than the bearing surface 19 on both sides of the first recess 110, which can make the operation space at the front side openings 12 larger, and facilitate the use of tweezers to pick up the magnets and pass through the front side openings 12 to place the magnets on the magnetic pad 20.

[0069] The rear side of the top of the base 10 is provided with a rear side support portion 103, which is integrated with the support portions of the corners and the middle of the rear side, and the rear side support portion 103 is separated from the front side middle support portion 101 and the two front side corner support portions 102 by the first recess 110 and the bearing surface 19 on both sides of the first recess 110, and the bearing surface 19 on both sides is lower than the top surface of each support portion, which is used for bearing the left top block 40 and the right top block 30. The top surfaces of the rear side support portion 103, the front side middle support portion 101 and the two front side corner support portions 102 can contact the corresponding positions of the bottom surface of the cover plate 70 around the periphery of the second recess 72.

[0070] The rear side support portion 103 and the front side middle support portion 101 of the base 10 are respectively provided with a longitudinal guide hole 16; and the front part and the rear part of the cover plate 70 are respectively provided with a longitudinal mounting hole 71 which penetrates through the cover plate 70, corresponding to the two guide holes 16. The guide rod upper segment 63 of each guide rod 60 is located in the mounting hole 71 on the corresponding side of the cover plate 70, and the two are threadedly connected to fixedly connect the guide rod 60 and the cover plate 70. The guide rod lower segment 64 of each guide rod 60 can extend into the guide hole 16 on the corresponding side of the base 10 and allow the guide rod lower segment 64 to move up and down in the guide hole 16, or the guide rod lower segment 64 can be completely separated from the guide hole 16 to adjust the positional relationship between the cover plate 70 and the base 10 at different stages of the assembly process.

[0071] For example, in the first state, the lower section 64 of the guide rod does not extend into the guide hole 16, and the combination of the cover plate 70 and the guide rod 60 is separated from the base 10. In the second state, the lower section 64 of the guide rod extends into the guide hole 16, and the cover plate 70 covers the base 10, at which time the bottom surface of the cover plate 70 is at a minimum distance from the top surface of the middle support portion 101, the corner support portion 102, and the rear support portion 103 of the front side of the base 10, the combination of the magnetic pad 20 and the magnet or magnet combination is located in the space formed by the first groove 110 and the second groove 72, and the left top block 40 and the right top block 30 fix the magnet or magnet combination from the left and right sides, and the cover plate 70 and the base 10 are fixed to the combination from above and below by the close contact of the groove bottoms of the respective grooves.

[0072] In the third state, the lower section 64 of the guide rod extends into the guide hole 16, but the cover plate 70 is above the base 10 and separated from the base 10, that is, the cover plate 70 and the guide rod 60 are slightly lifted, the combination of the magnetic pad 20 and the magnet or magnet combination is still located in the first groove 110 of the base 10, the second groove 72 of the cover plate 70 is separated from the combination, and the bottom surface of the cover plate 70 is away from the top surface of each support portion of the base 10, at which time the operation space at the front side opening 12 of the base 10 is further increased in the height direction, which facilitates the placement of the magnet to be bonded next through the front side opening 12 onto the magnetic pad 20 (the corresponding position of the magnetic pad 20 is provided with glue), so that the magnet is located on the left side or the right side of the magnet or magnet combination that has been bonded on the magnetic pad 20 (the contact surface of the newly placed magnet and the existing magnet or magnet combination is also provided with glue), forming a new magnet combination, and the new magnet combination and the magnetic pad 20 form a new combination. According to the number of magnets to be connected in the array, the second state and the third state will be implemented alternately several times (described in detail below).

[0073] Each guide rod 60 is provided with a notch 61 at the lower section 64 of the guide rod, which is recessed inward in the radial direction, which can be a single recess, multiple recesses separated at the same height, or a ring of recesses. The side surfaces of the front and rear sides of the base 10 are respectively provided with a transverse first sliding groove 15, which communicates to the guide hole 16 on the same side; the opening at the inner end of the first sliding groove 15 is referred to as the sliding groove outlet, and the height of the notch 61 on the guide rod 60 in the second state (that is, when the lower section 64 of the guide rod extends into the guide hole 16 and the cover plate 70 covers the base 10) corresponds to the height of the sliding groove outlet.

[0074] The stopper 50 fixedly connected with the side surface of the base 10 on both sides of the front and back is respectively provided with a transverse second sliding slot 55, which is communicated with the first sliding slot 15 on the same side of the base 10. Each stopper 50 is provided with two third bolts 54, which are connected to the base 10 through the stopper 50. The mounting holes of the base 10 for accommodating the two third bolts 54 are located on both sides of the first sliding slot 15, and the mounting holes of the stopper 50 for accommodating the two third bolts 54 are correspondingly located on both sides of the second sliding slot 55. The positioning block 52 arranged in each stopper 50 can move in the first sliding slot 15 and the second sliding slot 55, and the positioning block 52 has a transversely protruding head portion, which can protrude from the sliding slot outlet and enter the guide hole 16. The rod body of the operating rod 51 protrudes into the second sliding slot 55 of the stopper 50, and the head portion of the rod body is connected with the tail portion of the positioning block 52. The tail portion of the rod body is provided with the handle of the operating rod 51, and the diameter of the handle is greater than the diameter of the rod body, so that the handle is left outside the opening at the outer end of the second sliding slot 55.

[0075] The operating rod 51 of the example is a bolt, and the head portion of the rod body is provided with a thread for threadedly connecting with the tail portion of the positioning block 52. The head portion of the rod body can be a smooth rod. The second sliding slot 55 of the stopper 50 is further provided with a spring 53, which is sleeved on the rod body of the operating rod 51, one end of the spring 53 abuts against the end face of the tail portion in the second sliding slot 55, and the other end of the spring 53 abuts against the end face of the tail portion of the positioning block 52. The spring 53 is kept in a compressed state, so as to provide a pushing force (hereinafter referred to as spring pushing force) for the positioning block 52 through the elastic force of the spring 53.

[0076] The handle of the operating rod 51 is driven to move the rod body transversely in the second sliding slot 55, which can drive the positioning block 52 connected therewith to move transversely, so as to adjust the position of the head portion of the positioning block 52. For example, when the operating rod 51 is pulled out by a certain distance, the pulling force overcomes the elastic force of the spring 53, and the head portion of the positioning block 52 is retracted into the sliding slot outlet, which does not affect the up-down movement of the lower section 64 of the guide rod in the guide hole 16.

[0077] Without operating the operating lever 51, only under the action of spring thrust, the head of the positioning block 52 can be extended from the chute outlet and into the guide hole 16, the operating lever 51 is driven back to the push-in position by the positioning block 52 (or the operating lever 51 can be actively driven to push in, so that the head of the positioning block 52 is extended from the chute outlet and into the guide hole 16), at this time, if in the first state, the lower section 64 of the guide rod is not in the guide hole 16; if in the second state, the notch 61 of the lower section 64 of the guide rod corresponds to the position of the chute outlet, then the head of the positioning block 52 is embedded into the notch 61 to lock the guide rod 60, preventing the guide rod 60 from moving up and down; if in the third state, the guide rod 60 is slightly lifted with the cover plate 70, and the notch 61 of the lower section 64 of the guide rod is slightly higher than the position of the chute outlet, then under the action of spring thrust and / or operating lever thrust, the protruding head of the positioning block 52 can be against the rod body below the notch 61; if the guide rod 60 is further moved upward in the third state, so that the rod body of the guide rod 60 is higher than the chute outlet or the lower section 64 of the guide rod is taken out of the guide hole 16, then under the action of spring thrust and / or operating lever thrust, the head of the positioning block 52 is extended into the guide hole 16, returning to the first state; if the guide rod 60 is further moved downward in the third state, so that the notch 61 of the lower section 64 of the guide rod corresponds to the position of the chute outlet, then under the action of spring thrust and / or operating lever thrust, the head of the positioning block 52 is embedded into the notch 61 to lock the guide rod 60, returning to the second state.

[0078] As shown in Figure 1 , Figures 3-7 , the right top block 30 is generally a "-7" type structure, having a first main body transverse section 31 and a first main body longitudinal section 32, and a transverse first extension section 33 connected with the inner side of the first main body transverse section 31. The first main body longitudinal section 32 is provided with a first bolt hole 34 and a first pin hole 35 through it, and a base bolt hole 17 and two base pin holes 18 are provided on the right side of the base 10 corresponding to the first bolt hole 34 and the two first pin holes 35; the first bolt 13a installed in the corresponding first bolt hole 34 and base bolt hole 17 fixes and connects the right top block 30 with the base 10; the first pin 14a installed in the corresponding first pin hole 35 and base pin hole 18 plays a guiding role, after the first bolt 13a is locked, the first pin 14a can prevent the right top block 30 from being raised or raised too much, avoiding affecting the positioning accuracy of the right top block 30 when fixing the magnet and avoiding lifting the cover plate 70.

[0079] The left top block 40 and the right top block 30 are substantially similar in structure, each having a second main body transverse section 41 and a second main body longitudinal section 42, and a transverse second extension section 43 connected to the inner side of the second main body transverse section 41; but in order to distinguish the two top blocks, a notch 46 is provided on the second extension section 43 of the left top block 40. A second bolt hole 44 and two second pin holes 45 are provided through the second main body longitudinal section 42, corresponding to a base bolt hole 17 and two base pin holes 18 on the left side of the base 10, so that the left top block 40 is fixedly connected to the left side of the base 10 through a second bolt 13b in the middle, guided by two second pins 14b on both sides of the second bolt 13b, and prevented from being raised or raised too much by the second pins 14b when the second bolt 13b is locked, so as to ensure the positioning accuracy and avoid the lifting of the cover plate 70.

[0080] When the right top block 30 and the left top block 40 are fixedly connected to the base 10 respectively, the distance between the inner side of the first main body longitudinal section 32 and the second main body longitudinal section 42 of the two top blocks and the side of the base 10 can be adjusted by adjusting the length of the first bolt 13a and the second bolt 13b screwed into the base 10 (the length of the first pin 14a and the second pin 14b or the length of the first pin 14a and the second pin 14b inserted into the base 10 can be adjusted) at different stages of assembling the magnets. With the change of the distance, the bearing surface 19 beside the first groove 110 on the base 10 can be in full contact, partial contact or completely out of contact with the bottom surface of the first main body transverse section 31 and the second main body transverse section 41. After the magnetic pad 20 is placed in the first groove 110 on the base 10, the top surface of the magnetic pad 20 is at the same height as the bearing surface 19 (flush or with a small error; for example, the bearing surface 19 is slightly higher, but not as a limitation); the first extension section 33 and the second extension section 43 are above the bearing surface 19 and the magnetic pad 20 on the same side thereof (the first extension section 33 and the second extension section 43 can be in contact or not in contact with the top surface of the bearing surface 19 or the magnetic pad 20), and the inner side of the first extension section 33 and the second extension section 43 is used to contact the magnets on the magnetic pad 20, and the left and right sides of the magnets or the magnet combination are fixed between the first extension section 33 and the second extension section 43; similarly, with the change of the number of magnets on the magnetic pad 20, the distance between the inner side of the first main body longitudinal section 32 and the second main body longitudinal section 42 and the side of the base 10 changes, and the distance between the first extension section 33 and the second extension section 43 changes accordingly. It can be understood that the more magnets arranged on the magnetic pad 20, the larger the distance between the first extension section 33 and the second extension section 43 (matching the width of the current magnet combination), and the farther the left top block 40 and the right top block 30 are away from the side of the base 10. In some examples, the bearing surface 19 contacts the bottom surface of the first extension section 33 and the second extension section 43 to bear them, so that the first extension section 33 and the second extension section 43 are more stable when the top block moves.

[0081] The right top block 30 of the example has magnetic permeability as a whole, or at least the first extension section 33 of the right top block 30 has magnetic permeability, which can attract the magnets or the magnet combination to implement positioning and fixing; the left top block 40 has no magnetic permeability, and the two top blocks clamp the magnets or the magnet combination to implement fixing through the first extension section 33 and the second extension section 43 of the two top blocks. For example, the right top block 30 as a whole or the first extension section 33 of the right top block 30 is made of 430 stainless steel or other strong magnetic material and has magnetism; the left top block 40 is made of aluminum material. The top surface of the first extension section 33 and the second extension section 43 of the two top blocks is not higher than the top surface height of the magnets or the magnet combination, so that when the cover plate 70 is covered to the base 10, the groove bottom of the second groove 72 of the cover plate 70 can be pressed to the top surface of the magnets or the magnet combination to implement fixing.

[0082] In some optional examples, at least when the first main longitudinal section 32 of the right top block 30 and the second main longitudinal section 42 of the left top block 40 are closest to the side surface of the base 10, the respective support portions on the base 10 above the bearing surface 19 can cooperate to constrain the positions of the left top block 40 and the right top block 30 in the front-rear direction; for example, the inner side surfaces at the left and right ends of the rear side support portion 103 and the inner side surfaces of the two front side corner support portions 102 abut the front-rear side surfaces of the first main transverse section 31 and the second main transverse section 41 to limit the positions, so that the two top blocks can be more stable when moving closer to or away from the base 10, and the positioning accuracy of the top blocks after adjustment can be more easily ensured.

[0083] In other optional examples, the front side middle support portion 101 and the middle section of the rear side support portion 103 of the base 10 can cooperate to contact and fix the magnet or the magnet combination in the length direction of the magnet or the magnet combination. For example, the distance from the front side middle support portion 101 to the middle section of the rear side support portion 103 can be less than the distance from one end of the rear side support portion 103 to the front side corner support portion 102 at the front of the end.

[0084] When the above assembly jig is used for adhesive assembly of the magnets, as shown in Figure 5 The two stop blocks 50 are always connected to the base 10; the combined structure of the cover plate 70 and the guide rod 60 is first separated from the base 10, and the left top block 40 and the right top block 30 are also not connected to the base 10. The magnetic attraction gasket 20 is placed into the first groove 110 on the base 10; at this time, the operating rod 51 and the positioning block 52 of the stop block 50 are in the first state, the head of the positioning block 52 protrudes transversely from the sliding groove outlet and extends into the guide hole 16.

[0085] As shown in Figure 6 The right top block 30 is connected to the base 10 by the corresponding first bolt 13a (cooperating with the first pin 14a for guidance), so that the right top block 30 is in the position closest to the base 10, and the inner side surface of the first extension section 33 of the right top block 30 is used to position the middle magnet 81 in the array; in this example, when the position is closest, the inner side surface of the first main longitudinal section 32 of the right top block 30 is in close contact with the right side surface of the base 10. The middle magnet 81 is placed on the gasket position along the inner side surface of the first extension section 33 of the right top block 30, so that the right side of the middle magnet 81 is in close contact with the inner side surface of the first extension section 33 of the right top block 30; the right top block 30 or the first extension section 33 thereof has magnetism to further firmly attract the middle magnet 81.

[0086] As shown in Figure 7As shown, the left top block 40 is connected to the base 10 through the corresponding second bolt 13b (guided by the second pin 14b), so that the left top block 40 is in the position closest to the base 10, for example, the inner side of the second main longitudinal section 42 of the left top block 40 is in close contact with the left side of the base 10. At this time, the inner side of the second extension section 43 of the left top block 40 is in close contact with the left side of the middle magnet 81, and the left-right direction of the middle magnet 81 is fixed by the first extension section 33 and the second extension section 43 of the two top blocks.

[0087] As shown, Figure 8 As shown, the combination structure of the cover plate 70 and the guide rod 60 is installed on the base 10, and the lower section 64 of the guide rod extends into the corresponding guide hole 16; as the lower section 64 of the guide rod extends, the head of the positioning block 52 first contacts the rod body below the notch 61, and then is embedded into the notch 61 to lock the guide rod 60, reaching the second state; unless a large external force acts (such as lifting the guide rod 60 upward), the locked guide rod 60 cannot move up and down.

[0088] At this time, the cover plate 70 covers the base 10, and the outer periphery of the bottom surface of the cover plate 70 is in the minimum distance from the top surface of each support part (the front middle support part 101, the front corner support part 102, and the rear support part 103) of the base 10; the groove bottom of the first groove 110 on the base 10 bears the middle magnet 81 and the magnetic attraction pad 20, and the cover plate 70 is in close contact with the top of the middle magnet 81 through the groove bottom of the second groove 72, and the cover plate 70 and the base 10 respectively fix the combination of the middle magnet 81 and the magnetic attraction pad 20 from above and below. The nut 62 of the upper section 63 of the guide rod can be further locked, so that the assembled guide rod 60 and the cover plate 70 are in a locked state, and a downward force is applied to the cover plate 70 to ensure that the cover plate 70 does not lift up and the perpendicularity of the cover plate 70 relative to the guide rod 60 is ensured.

[0089] Then, the first curing is performed, and the glue for bonding the middle magnet 81 is cured.

[0090] As shown, Figure 9 After the first curing is completed, the bolts of the left top block 40 and the right top block 30 are loosened, so that the left top block 40 and the right top block 30 are respectively away from the side surface of the base 10 by a certain distance, at least leaving the pad positions for placing the middle magnets 82 on the left and right sides of the middle magnet 81, and the middle magnets 81 and the pad positions on the left and right sides of the middle magnet 81 are glued through the front opening 12 on the base 10.

[0091] When the combined structure of the cover plate 70 and the guide rod 60 is slightly lifted (the bottom surface of the cover plate 70 is not in contact with each support portion of the base 10), and the operating rod 51 is pulled out, the spring 53 is overcome, the head of the positioning block 52 is first retracted into the first sliding slot 15 by the operating rod 51, and when the notch 61 of the lower section 64 of the guide rod is higher than the outlet of the sliding slot, the operating rod 51 is released or pushed in, under the action of the spring and / or the operating rod, the head of the positioning block 52 is re-extended out of the outlet of the sliding slot and abuts against the rod body of the guide rod 60 below the notch 61, reaching the third state.

[0092] Because the cover plate 70 is slightly lifted, the operation space at the front opening 12 of the base 10 is increased, and the interval magnets 82 held by the tweezers can be placed on the magnetic pad 20 through the front opening 12, so that the two interval magnets 82 are tightly attached to the left and right sides of the middle magnet 81, forming a first magnet combination of the middle magnet 81 and the interval magnets 82 (the middle magnet 81 is between the two interval magnets 82).

[0093] As shown in Figure 10 , the combined structure of the cover plate 70 and the guide rod 60 is lowered, the head of the positioning block 52 returns from the third state to the second state and is re-embedded in the notch 61 of the lower section 64 of the guide rod 60, and the guide rod 60 is locked again. The cover plate 70 covers the base 10, the bottom surface of the cover plate 70 is tightly in contact with the top surface of each support portion of the base 10, and the cover plate 70 is tightly in contact with the top of the first magnet combination through the groove bottom of the second groove 72, cooperating with the groove bottom of the first groove 110 of the base 10 to bear the first magnet combination and the magnetic pad 20. The cover plate 70 and the base 10 respectively fix the combination of the magnetic pad 20 and the first magnet combination from above and below.

[0094] Moreover, the first bolt 13a of the right top block 30 and the second bolt 13b of the left top block 40 are re-tightened (cooperating with the first pin 14a and the second pin 14b for guidance), and the right top block 30 and the left top block 40 are connected with the base 10, so that the first extension section 33 and the second extension section 43 of the two top blocks are tightly in contact with the first magnet combination from left and right directions, and the first magnet combination is fixed. It can be understood that because the number of arranged magnets is increased, the inner side surfaces of the first main body longitudinal section 32 and the second main body longitudinal section 42 of the two top blocks are separated from the side surfaces of the base 10 by a certain distance.

[0095] Then, the second curing is performed, and the glue for bonding the interval magnets 82 is cured.

[0096] As shown in Figure 11 , Figure 12 , after the second curing is completed, the related operations between the first curing and the second curing are repeated to place and fix the outer magnet 83.

[0097] According to Figure 11Loosen the first bolt 13a of the right top block 30 and the second bolt 13b of the left top block 40 again, so that the right top block 30 and the left top block 40 are each away from the side of the base 10 by a certain distance, at least leaving the gasket position for placing the outer magnet 83 on the left and right sides of the first magnet combination. Through the front side opening 12 of the base 10, the first magnet combination is glued on the left and right sides and the gasket position points on the left and right sides of the combination.

[0098] Again slightly lift the combined structure of the cover plate 70 and the guide rod 60 (the bottom surface of the cover plate 70 does not contact each support part of the base 10), cooperate with the operating rod 51 to pull the positioning block 52 outward, overcome the elastic force of the spring 53, so that the head of the positioning block 52 exits from the notch 61 of the guide rod 60, first shrink into the first sliding groove 15, and then release the operating rod 51 or push the operating rod 51 inward after the guide rod 60 moves upward to make the notch 61 higher than the sliding groove outlet. Under the action of the spring thrust and / or the operating rod thrust, the head of the positioning block 52 is re-stretched out from the sliding groove outlet and abuts on the rod body of the guide rod 60 below the notch 61, that is, the positioning block 52 is converted from the second state to the third state.

[0099] Place the outer magnet 83 held by the tweezers on the magnetic gasket 20 through the front side opening 12, so that the two outer magnets 83 are tightly attached to the left and right sides of the first magnet combination (i.e. tightly attached to the adjacent interval magnet 82), forming a second magnet combination of three kinds of five magnets (the middle magnet 81 is in the middle, the outer magnet 83 is on the outside, and the interval magnet 82 is between the middle magnet 81 and the outer magnet 83).

[0100] According to Figure 12 Put down the combined structure of the cover plate 70 and the guide rod 60, the positioning block 52 returns from the third state to the second state, and the head is re-embedded into the notch 61 of the lower section 64 of the guide rod 60, so that the guide rod 60 is locked again. The cover plate 70 covers the base 10, the bottom surface of the cover plate 70 is in close contact with each support part of the base 10, and the cover plate 70 is in close contact with the top of the second magnet combination through the groove bottom of the second groove 72. The cover plate 70 and the base 10 respectively fix the combined body of the magnetic gasket 20 and the second magnet combination from above and below.

[0101] And, the first bolt 13a of the right top block 30 and the second bolt 13b of the left top block 40 are locked again (guided by the first pin 14a and the second pin 14b), the right top block 30 and the left top block 40 are connected with the base 10, and the first extension section 33 and the second extension section 43 of the two top blocks are in close contact with the second magnet combination from the left-right direction to fix the second magnet combination. It can be understood that, due to the further increase of the arranged magnets, the distance between the inner side of the first main body longitudinal section 32 and the second main body longitudinal section 42 of the two top blocks and the side of the base 10 is larger than the distance at the position during the second curing.

[0102] Then, the third curing is performed, and the glue for bonding the outer magnets 83 is cured.

[0103] If there are more magnets to be bonded, the related operations between any two curing stages can be further repeated: for example, the two top blocks are moved away from the base 10 by a certain distance, the glue is applied to the positions of the gaskets on both sides of the current magnet combination and the positions of the gaskets left on both sides, the cover plate 70 and the guide rod 60 are lifted, the head of the positioning block 52 is withdrawn from the notch 61 of the lower section 64 of the guide rod 60 to unlock the guide rod 60, two new magnets are symmetrically placed on both sides of the current magnet combination to form a new magnet combination, the cover plate 70 and the guide rod 60 are lowered, the new magnet combination is pressed by the cover plate 70, the two top blocks are locked to the base 10 again, the new magnet combination is fixed between the first extension section 33 and the second extension section 43, and the glue is cured.

[0104] After the last curing is completed (in this example, after the third curing is completed), the magnet combination on the magnetic gasket 20 meets the requirements of the Halbach array, and the magnets and the magnetic gasket 20 and the adjacent magnets are firmly connected together. The combination structure of the cover plate 70 and the guide rod 60 is removed from the base 10 (the lower section 64 of the guide rod is withdrawn from the guide hole 16; under the action of the spring force, the head of the positioning block 52 is located in the guide hole 16 and is in the first state), the first bolt 13a of the right top block 30 and the second bolt 13b of the left top block 40 are loosened, and the right top block 30 and the left top block 40 are removed from the base 10. The combination of the magnetic gasket 20 and the magnet combination is removed, and the assembly operation is completed.
