Description

Technical Field

[0001] The present application relates to the technical field of Halbach arrays, and in particular to an assembly method of Halbach strong magnets. Background Art

[0002] The Halbach array is a magnetic structure that is a near-ideal structure in engineering. Its goal is to produce the strongest magnetic field with the least number of magnets. It arranges magnets with different magnetization directions in a certain smooth arrangement, so that the magnetic field on one side of the array is significantly enhanced, which is of great significance in engineering.

[0003] The Halbach array is formed by arranging and assembling a number of magnets. The quality of the arrangement affects the unidirectional magnetic field strength of the Halbach array magnet, and the size of the gaps between the magnets also affects the magnetic field strength of the Halbach array magnet. For example, a method for integrally magnetizing a Halbach array magnet assembly, disclosed in publication number CN112530658A, includes the following steps: 1) selecting a suitable blank; 2) first machining the blank assembly direction to a specified size; 3) assembling the blanks into a Halbach array according to different magnetization directions to form a Halbach array assembly; 4) then machining the assembled Halbach array assembly to the required size to form a Halbach array semi-finished product; 5) performing surface treatment on the Halbach array semi-finished product; and 6) integrally magnetizing the surface-treated Halbach array semi-finished product to form a Halbach array magnet. The present invention has the following beneficial effects: the Halbach array magnet is assembled without magnetizing first, eliminating the influence of repulsive force, increasing the safety factor of employee operation, and greatly reducing the difficulty of assembly.

[0004] The above-mentioned prior art assembles the components without magnetizing them and then magnetizes them uniformly. Although there is no repulsive force during assembly, which can reduce the difficulty of assembly, the magnets are arranged intermittently in the vertical and horizontal directions. Therefore, the magnetization fixture needs to be magnetized in two steps (horizontally and vertically). In addition, since adjacent magnets are bonded by glue, the magnetism of adjacent magnets will be affected during magnetization, and the magnetization effect of adjacent magnets will be poor during the second magnetization.

[0005] In addition, currently, when arranging and assembling magnets, the magnets are first arranged and then glue is injected one by one to connect and fix two adjacent magnets. Finally, pressure is applied from both sides to ensure that the adjacent magnets are firmly bonded. This bonding method can assemble magnets faster, but it cannot guarantee the gap between two adjacent magnets, which easily leads to the problem of uneven magnetic distribution in different parts of the Halbach array.

[0056] The bottom support 2 includes a bottom support plate 21 slidably arranged in the assembly square tube 1, a guide bar 22 extending from the side wall of the bottom support plate 21, and a guide groove 23 is opened on the side wall of the assembly square tube 1 to facilitate the sliding of the guide bar 22. The outer side wall of the assembly square tube 1 is provided with a downward stabilizer 5 connected to the guide bar 22, and the downward stabilizer is intermittently cooperated with the T-bar 32.

[0057] During the specific implementation process, the bottom support plate 21 of the present invention is used to support the magnet 100 in the assembly square tube 1, and is used to drive the magnet 100 in the assembly square tube 1 to dock and assemble with the cooperation of the down-presser 3; and the present invention can control the bottom support plate 21 to be fixed on the assembly square tube 1 by pressing the stabilizer down, or the downward stabilizer 5 can cooperate with the down-presser 3 to realize the overall synchronous downward movement of the magnet 100 in the assembly square tube 1 that has been glued, so as to facilitate the subsequent assembly of the newly installed magnet 100 in the square tube 1 to be glued and fixed with the already assembled Halbach array magnet 100 by glue.

[0058] The assembly method using the Halbach ferromagnet 100 assembly device includes the following steps:

[0059] Step S1: Pre-assembly process: after checking whether all parts of the assembly device are operating normally, a magnet 100 is placed in the assembly square tube 1 and supported on the bottom support plate 21;

[0060] Step S2: Move down and glue is poured. Then, the next magnet 100 is placed into the assembly square tube 1. Then, the T-shaped rod 32 is pushed by the existing downward pressing mechanism to make the lower pressing plate 31 push the magnet 100 downward. Before docking with the magnet 100 in step S1, the glue pouring device 4 will pour glue on the upper end surface of the magnet 100 in step S1.

[0061] Step S3: Butt bonding, following step S2, after the glue dispenser 4 has finished pouring glue, the magnet 100 placed in step S2 is bonded to the magnet 100 in step S1 by glue;

[0062] Step S4: Stabilize and move downward. After the bonding of the magnet 100 in step S3 is completed, the T-shaped rod 32 is clamped and fixed with the downward pressure stabilizer, so that the two magnets 100 located between the lower pressing plate 31 and the bottom supporting plate 21 move downward as a whole until the glue injector 4 can restrict the upward movement of the magnet 100 and fix the magnet 100 between the glue injector 4 and the bottom supporting plate 21;

[0063] Step S5: Repeat the operation. After completing step S4, the T-shaped rod 32 is disengaged from the downward movement stabilizer 5, and the lower pressing plate 31 is driven to move upward and reset by the downward pressure mechanism, so as to repeat steps S2-4 until the assembly of the Halbach array magnet 100 is completed.

[0064] The downward pressure stabilizer includes a stabilizing block 51 arranged between two guiding bars 22 and is fixed on the guiding bars 22 by bolts. A downward movement bar 52 is arranged at the upper end of the stabilizing block 51, and a downward movement control member 53 is arranged between the stabilizing block 51, the downward movement bar 52 and the side wall of the assembly square cylinder 1.

[0065] In the specific implementation process, the downward movement control member 53 can control the sliding of the stabilizing block 51 on the side wall of the assembly square cylinder 1, thereby controlling the sliding of the bottom supporting plate 21 in the assembly square cylinder 1. At the same time, the downward movement control member 53 can connect the downward movement bar 52 to the stabilizing block 51; secondly, after the Halbach array magnet 100 in the assembly square cylinder 1 is assembled, the bolt on the guiding bar 22 is screwed to disassemble the stabilizing block 51 and the guiding bar 22, so as to facilitate the removal of the Halbach array magnet 100 in the assembly square cylinder 1.

[0066] Refer to Figure 4-5 , the downward movement control member 53 includes a C-shaped cavity 531 opened on one side of the stabilizing block 51 facing the assembly square cylinder 1, and a C-shaped insert bar 532 slidably arranged in the C-shaped cavity 531. The two horizontal segments of the C-shaped insert bar 532 slidably penetrate through the stabilizing block 51. A plurality of insertion cavities 533 engaged with the two horizontal segments of the C-shaped insert bar 532 are uniformly opened on the outer side wall of the assembly square cylinder 1 from top to bottom. A pressing spring 534 is arranged between the C-shaped insert bar 532 and the C-shaped cavity 531.

[0067] In the specific implementation process, when it is necessary to fix the bottom supporting plate 21 in the assembly square cylinder 1 and restrict the movement of the bottom supporting plate 21, the C-shaped insert bar 532 is pulled towards the assembly square cylinder 1 under the pulling of the pressing spring 534 until the two horizontal segments of the C-shaped insert bar 532 are inserted into the insertion cavities 533 on the side wall of the assembly square cylinder 1. At this time, the bottom supporting plate 21 can be limited and fixed on the assembly square cylinder 1.

[0068] The top of the stabilizing block 51 is provided with a stabilizing cavity 535 communicating with the C-shaped cavity 531. The lower end of the downward movement bar 52 is slidably inserted into the stabilizing cavity 535. On the bottom of the downward movement bar 52 and on the side facing the C-shaped insertion bar 532, a through strip-shaped hole 536 is provided, and the strip-shaped hole 536 is slidably engaged with the C-shaped insertion bar 532. At one end of the stabilizing cavity 535 facing away from the C-shaped insertion bar 532, an electromagnetic sheet 537 is provided for driving the C-shaped insertion bar 532 to move towards the stabilizing cavity 535.

[0069] In the specific implementation process, when it is necessary to control the downward movement of the bottom support plate 21, the electromagnetic sheet 537 is powered on to drive the C-shaped insertion bar 532 to move towards the electromagnetic sheet 537 until the C-shaped insertion bar 532 moves into the strip-shaped hole 536 of the downward movement bar 52. At this time, the two horizontal segments of the C-shaped insertion bar 532 are disengaged from the groove and insertion hole, and at this time, the downward movement bar 52 can control the movement of the bottom support plate 21.

[0070] Refer to Figure 6 , a plurality of intermittent bars 54 are provided at the upper end of the downward movement bar 52 and are distributed from top to bottom and on the same vertical line as the downward movement bar 52. The upper end of the intermittent bar 54 is provided with a T-shaped hole 541, and a T-shaped block 542 is provided at the lower end of the intermittent bar 54 and is inserted and mated with the T-shaped hole 541 at the upper end of the adjacent intermittent bar 54 below. A T-shaped hole 541 is also provided at the upper end of the downward movement bar 52 and is inserted and mated with the T-shaped block 542 at the lower end of the intermittent bar 54 above it; through the insertion and mating of the T-shaped block 542 and the T-shaped hole 541, the connection between the intermittent bar 54 and the downward movement bar 52 can be realized, so as to connect the adjacent two downward movement bars 52.

[0071] Refer to Figure 7 , a temporary storage box 55 is provided on the side wall of the assembly square tube 1, and the temporary storage box 55 is on the same side of the assembly square tube 1 as the downward movement bar 52. The bottom surface of the T-shaped hole 541 at the top of the intermittent bar 54 at the topmost position on the same vertical line as the downward movement bar 52 is flush with the inner bottom surface of the temporary storage box 55; a plurality of intermittent bars 54 are also slidably provided in the temporary storage box 55 along its horizontal direction. A push plate 551 is slidably provided on one side inside the temporary storage box 55, and the push plate 551 and the inner side wall of the temporary storage box 55 are connected by a top push spring 552. The T-shaped block 542 at the lower end of the intermittent bar 54 on the side of the temporary storage box 55 facing away from the push plate 551 and the T-shaped hole 541 at the top of the intermittent bar 54 at the topmost position on the same vertical line as the downward movement bar 52 are slidably inserted; the top push spring 552 can always push the push plate 551, so that the intermittent bar 54 in the temporary storage box 55 always moves in the direction away from the top push spring 552, ensuring that the intermittent bar 54 on the side of the temporary storage box 55 facing away from the push plate 551 can be slidably inserted into the T-shaped hole 541 at the top of the intermittent bar 54 at the topmost position on the same vertical line as the downward movement bar 52.

[0072] It should be noted that the length of the intermittent strip 54 can be replaced according to the thickness of the magnet 100 to ensure that the height of the lower movement of the bottom support plate 21 driven by each assembled magnet 100 is the length of the intermittent strip 54.

[0073] Looking back Figure 4 , a clamping plate 56 is provided on the T-shaped rod 32 and on the same side as the temporary storage box 55. The clamping plate 56 and the T-shaped hole 541 at the top of the intermittent strip 54 in the temporary box and on the same vertical line as the downward movement strip 52 are clamped and matched through a clamping control member 57.

[0074] In the specific implementation process, when the T-shaped rod 32 moves downward, it带动 the clamping plate 56 to move downward synchronously. When the pressing plate 31 pushes the magnet 100 downward and bonds with the magnet 100 at the uppermost end of the Halbach array magnet 100, the lower end of the clamping plate 56 is clamped and matched with the top of the intermittent strip 54 located in the temporary storage box 55 and on the same vertical direction as the downward movement strip 52 through the clamping control member 57. At this time, the electromagnetic sheet 537 is powered on to drive the C-shaped insert 532 to move into the strip hole 536, so that the downward movement strip 52 is connected and fixed to the stabilizing block 51. The stabilizing block 51 slides with the assembly square tube 1, thereby ensuring that the T-shaped rod 3, the pressing plate 31, the bottom support plate 21, the stabilizing block 51, the downward movement strip 52, the intermittent strip 54, the clamping plate 56, and the Halbach array magnet 100 located between the pressing plate 31 and the bottom support plate 21 form a whole and move downward synchronously under the action of the downward pressing machine.

[0075] Specifically, referring to Figure 8 , the clamping control member 57 includes a clamping cavity opened on one side of the bottom of the clamping plate 56 and背离 the assembly square tube, and an elastic clamping block 571抵触配合 with the horizontal section of the T-shaped hole 541 of the intermittent strip 54 is provided in the clamping cavity. On the bottom of the elastic clamping block 571 and背离 the clamping plate 56, a clamping slope 572 facilitating the insertion of the clamping plate 56 into the T-shaped hole 541 is provided; through the抵触配合 of the clamping slope 572 of the elastic clamping block 571 with the vertical section 4621 of the T-shaped hole 541, it is ensured that the elastic clamping block 571 can be顺利 inserted into the bottom of the T-shaped hole which makes the elastic clamping block 571 able to抵触配合 with the horizontal section of the T-shaped hole 541, thereby restricting the up and down movement of the clamping plate 56 and实现 the clamping and fixing of the clamping plate 56 and the intermittent strip 54.

[0076] Referring to Figure 7-8 It should be noted that there are some inaccuracies in the original text, such as "带动" which should be "带动", "背离" which should be "背离", "抵触配合" which should be "抵触配合", "顺利插入" which should be "顺利插入", "实现" which should be "实现". The above translation has made corresponding corrections., on the bottom of the temporary storage box 55, on the side背离 the formula loading cylinder 1, there is a permanent magnet 573 located in the same vertical direction as the downward moving strip 52, and the horizontal section of the T-shaped block 542 at the bottom of the intermittent strip 54 in the temporary storage box 55 is on the same horizontal plane as the permanent magnet 573. A through hole 574 is opened at the same horizontal plane as the horizontal section of the T-shaped hole 541 on the side of the intermittent strip 54背离 the formula loading cylinder 1. On the side of the elastic clamping block 571 facing the through hole 574, there is an adapter magnetic sheet 575 with the same magnetic property as the permanent magnet 573 on the side wall of the temporary storage box 55.

[0077] In the specific implementation process, the above-mentioned T-shaped rod 32, lower pressing plate 31, bottom supporting plate 21, stabilizing block 51, downward moving strip 52, intermittent strip 54, clamping plate 56, and the Halbach array magnet 100 located between the lower pressing plate 31 and the bottom supporting plate 21 form a whole and move downward synchronously under the action of the downward pressing machine. When the upper surface of the magnet 100 at the uppermost end in the formula loading cylinder 1 contacts the lower surface of the abutting block 42, and the abutting block 42 restricts the upward movement of the magnet 100. At this time, the electromagnetic sheet 537 is powered off, and under the action of the abutting spring 534, the two horizontal sections of the C-shaped insertion strip 532 are inserted into the insertion cavity 533 on the side wall of the formula loading cylinder 1 to restrict the movement of the bottom supporting plate 21. At the same time, the bottom of the clamping plate 56 drives the connected intermittent strip 54 to move to the bottom of the temporary storage box 55, so that the adapter magnetic sheet 575 on the elastic clamping block 571 faces the permanent magnet 573 through the through hole 574. Then, under the repulsive force between the two, the elastic clamping block 571 moves towards the clamping plate 56 until the elastic clamping block 571 no longer抵触配合 with the horizontal section of the T-shaped hole 541. Then, under the action of the downward pressing machine, the clamping plate 56 is driven to move upward and脱离出 the T-shaped hole 541 and return to the initial position.

[0078] Embodiment Two:

[0079] Refer to Figure 9-11 , the glue injector 4 includes two through glue injection ports opened on both side walls of the formula loading cylinder 1. On the side背离 the formula loading cylinder 1 of the glue injection port, there is a square guiding frame 41 with a hollow structure. Abutting blocks 42 are slidably arranged in the square guiding frame 41, and a guiding spring 43 is connected between the abutting blocks 42 and the inner side wall of the square guiding frame 41. On the upper end of the side of the abutting block 42 located in the formula loading cylinder 1, there is a guiding slope 421.

[0080] A glue injection channel 422 for glue flow is opened in the abutting block 42. The outlet of the glue injection channel 422 is on the guiding slope 421. The inlet of the glue injection channel 422 is at the upper end of the side of the abutting block 42背离 the formula loading cylinder 1, and an elastic covering door 423 is arranged at this inlet to control the flow of glue in the glue injection channel 422. A glue injection cylinder 44 is arranged on the abutting block 42 at the inlet of the glue injection channel 422, and a glue pushing member 45 is arranged in the glue injection cylinder 44.

[0081] In the specific implementation process, the glue pushing member 45 moves within the glue filling cylinder 44 to push the glue pre-stored in advance in the glue filling cylinder 44 through the glue filling channel 422 of the pressing block 42 to the upper surface of the magnet 100, providing glue for the docking and bonding of the magnet 100; when the lower pressing plate 31 pushes the magnet 100 downward to contact the pressing block 42, at this time, the magnet 100 continues to move downward and抵触配合with the guiding slope 421 of the pressing block 42, driving the pressing block 42 to move into the square guiding frame 41 until the magnet 100 is bonded to the magnet 100 located at the lower end of the pressing block 42 through glue. At this time, the clamping plate 56 is clamped with the intermittent strip 54, and the U-shaped insert 532 disengages from the insertion cavity 533 and moves into the strip hole 536. The lower pressing mechanism continues to push the lower pressing plate 31 downward until the uppermost magnet 100 in the mounting square cylinder 1 moves downward until its upper end surface is flush with the lower end surface of the pressing block 42. Since the side wall of the lower pressing plate 31 is provided with a dislocation opening 313 (shown in Figure 8 ) facilitating the sliding fit of the pressing block 42, the pressing block 42 is pushed by the guiding spring 43 to move into the mounting square cylinder 1 until the pressing block 42 restricts the upward movement of the magnet 100. At this time, the U-shaped insert 532 disengages from the strip hole 536 and inserts into the insertion cavity 533, and the clamping plate 56 disengages from the T-shaped hole 541 of the intermittent strip 54.

[0082] Refer to Figure 12 , the glue pushing member 45 includes a piston plate 451 slidably disposed within the glue filling cylinder 44. The top of the piston plate 451 is connected to a glue pushing rod 452, and the upper end of the glue pushing rod 452 slidably penetrates through the glue filling cylinder 44. A material control plate 453 is slidably disposed on the glue pushing rod 452, and the material control plate 453 is slidably disposed within the glue filling cylinder 44. A return spring 454 is connected between the material control plate 453 and the piston plate 451; a limiting rod 455 for restricting the reset distance of the piston plate 451 is disposed at the lower end of the material control plate 453.

[0083] A plurality of material control screw rods 456 are rotatably connected to the upper end of the material control plate 453, and the upper ends of the material control screw rods 456 penetrate through the glue filling cylinder 44 and are threadedly connected to a material control gear 457 rotatably disposed at the top of the glue filling cylinder 44. A material control internal gear ring 458 meshing with the material control gear 457 is rotatably disposed at the top of the glue filling cylinder 44.

[0084] In the specific implementation process, the glue pushing rod 452 pushes the piston plate 451 downward to push the glue in the glue filling cylinder 44 into the glue filling channel 422, and then to the upper surface of the magnet 100. When the glue filling is completed, under the pulling of the return spring 454, the piston plate 451 returns to the initial position. In the present invention, a limiting rod 455 is disposed at the bottom of the material control plate 453 to limit the upward movement distance of the piston plate 451, and thus the content of the newly replenished glue in the glue filling cylinder 44, preventing too much or too little glue from being replenished in the glue filling cylinder 44.

[0085] When it is necessary to change the glue content when bonding the magnet 100, rotate the material control inner gear ring 458 to rotate the material control gear 457, and then drive the material control screw 456 to drive the material control plate 453 to move, thereby changing the distance from the piston plate 451 to the bottom of the glue filling cylinder 44, and controlling the change of the glue content in the glue filling cylinder 44.

[0086] See Figure 13 The side wall of the assembled square tube 1 is provided with a control component 46 (at Figure 11 ), the control component 46 includes a control square hole 461 opened on the side wall of the assembly square cylinder 1 and located above the square guide frame 41, and a guide bar 462 is provided on the side wall of the control square hole 461, so that the control panel 463 slidingly set in the control square hole 461 can slide with the guide bar 462 through the guide notch opened on its side wall, and the upper and lower ends of the guide bar 462 are respectively a vertical section 4621 and an inclined section 4622 inclined away from the assembly square cylinder 1. The end of the control panel 463 facing the assembly square cylinder 1 is in contact with the magnet 100 installed in the assembly square cylinder 1, and the end of the control panel 463 away from the assembly square cylinder 1 is extended with a control section that cooperates with the rubber pushing rod 452, and the control section is slidably set between the two material control screw rods 456; the bottom of the control square hole 461 is provided with a mounting groove for facilitating the installation of a spring rod 464, and the upper end of the spring rod 464 slides with the control panel 463.

[0087] During the specific implementation process, when the magnet 100 moves downward and contacts the control panel 463, the control panel 463 is pushed downward. Since the control panel 463 is slidingly set on the guide bar 462, and the upper end of the guide bar 462 is a vertical section 4621, and the lower end is an inclined section 4622, when the control panel 463 moves downward to the inclined section 4622, the control panel 463 will move in the direction away from the assembly square tube 1 until the control panel 463 is separated from the magnet 100, and then the control panel 463 moves up to the initial position under the push of the spring rod 464; wherein the control panel 463 will push the glue pushing rod 452 to move downward synchronously during the downward movement until the control panel 463 contacts the upper surface of the material control inner gear ring 458, at this time, the glue in the glue filling cylinder 44 is injected into the magnet 100, which is convenient for the subsequent bonding and docking of the magnet 100.

[0088] Replay Figure 10-11, a glue filling component 47 is arranged between two square guiding frames 41. The glue filling component 47 includes a material storage box 471 fixed between the two square guiding frames 41. A T-shaped pressing plate 472 for pressing glue is slidably arranged in the material storage box 471. Two C-shaped bars 473 slidably arranged on the outer side wall of the material storage box 471 are connected to the top of the T-shaped pressing plate 472. A one-way moving part 474 for restricting the upward movement of the T-shaped pressing plate 472 is arranged between the C-shaped bar 473 and the material storage box 471. A glue conveying pipe 475 is connected between the bottom of the material storage box 471 and the side wall of the lower end of the glue filling cylinder 44.

[0089] In the specific implementation process, after the glue pushing rod 452 moves downward to inject the glue in the glue filling cylinder 44 onto the magnet 100, under the action of the return spring 454, the piston plate 451 returns to the initial position. At this time, the glue filling cylinder 44 is in an empty glue state, and the air pressure inside it is lower than the external air pressure. Since an elastic covering door 423 is arranged at the inlet of the glue filling channel 422, it can effectively prevent the glue in the glue filling channel 422 from flowing back into the glue filling cylinder 44. At this time, under the action of the T-shaped pressing plate 472, the glue in the material storage box 471 enters the glue filling cylinder 44 through the glue conveying pipe 475. Due to the existence of the elastic covering door 423, it can prevent the glue in the material storage box 471 from being conveyed onto the magnet 100 through the glue filling channel 422. At the same time, in the present invention, the one-way moving part 474 can prevent the glue in the glue filling cylinder 44 from flowing back into the material storage box 471 through the glue conveying pipe 475 when the glue pushing rod 452 pushes the piston plate 451 downward.

[0090] Specifically, referring to Figure 14 , the one-way moving part 474 includes a vertical section 4621 of the C-shaped bar 473, and a one-way groove is formed on the side facing the material storage box 471. A one-way tooth 4741 is slidably arranged in the one-way groove. A tension spring 4742 is connected between the one-way tooth 4741 and the one-way groove. A pull rod 4743 slidably penetrating the C-shaped bar 473 is connected to the side of the one-way tooth 4741背离 the material storage box 471. A limiting bar 4744 is arranged on the material storage box 471 and opposite to the one-way tooth 4741. A limiting tooth groove for limiting the upward movement of the T-shaped pressing plate 472 and in limiting cooperation with the one-way tooth 4741 is arranged on the limiting bar 4744 facing the one-way tooth 4741.

[0091] In the specific implementation process, in the present invention, through the cooperation of the one-way tooth 4741 and the limiting tooth groove, it can be ensured that the C-shaped bar 473 can move downward and restrict the upward movement of the C-shaped bar 473. When the T-shaped pressing plate 472 needs to be removed from the material storage box 471, the pull rod 4743 is pulled to make the one-way tooth 4741脱离 the limiting cooperation with the limiting tooth groove, so that the C-shaped bar 473 can move upward, and thus the T-shaped pressing plate 472 can be taken out.

[0092] Since there is a torque force between adjacent magnets 100 when assembling the magnets 100, in order to ensure the neatness of the assembly of the Halbach array magnet 100, the assembly square cylinder 1 of the present invention and the magnet 100 are precisely slidably matched to ensure the neatness of the assembly of the Halbach array magnet 100. Therefore, when the lower pressing plate 31 pushes the magnet 100 downward, the gas in the assembly square cylinder 1 cannot be effectively discharged, which will affect the docking and bonding of the magnet 100. Specifically, looking back Figure 8-9 The present invention provides an air guide groove 11 at the corner of the inner wall of the assembly square cylinder 1, the upper end of which passes through the assembly square cylinder 1, for discharging the gas in the assembly square cylinder 1. A hinged step 311 is formed at the corner of the upper end of the lower pressure plate 31. The side wall of the hinged step 311 is hinged with a through groove plate 312 that slides with the air guide groove 11 through a torsion spring, and the bottom of the through groove plate 312 rests on the hinged step 311.

[0093] When the magnet 100 moves downward, the gas in the assembled square tube 1 can push open the through-groove plate 312 in the air guide groove 11, thereby achieving the discharge of gas. When the lower pressure plate 31 moves upward, the through-groove plate 312 can scrape the inside of the air guide groove 11 to prevent the glue from blocking the air guide groove 11 and affecting the subsequent assembly of the Halbach array magnet 100.

[0094] The implementation principle of the present invention is:

[0095] (1): First, place a magnet 100 into the assembly square tube 1 and support it on the bottom support plate 21, while ensuring that the bottom surface of the clamping block 42 can contact the upper surface of the magnet 100. At this time, the bottom support plate 21 is fixed to the side wall of the assembly square tube 1 by the downward control member 53;

[0096] (2): Next, the next magnet 100 is placed into the assembly square tube 1, and then the T-shaped rod 32 is pushed by the existing downward pressing mechanism so that the lower pressing plate 31 pushes the magnet 100 downward, and the magnet 100 presses the control panel 463 downward to drive the glue pushing member 45 to move downward, thereby transferring the glue pre-stored in the glue filling tube 44 through the glue filling channel 422 on the pressing block 42 to the upper surface of the magnet 100 in contact with the bottom surface of the pressing block 42;

[0097] (3): Then the magnet 100 continues to move downward and pushes the pressing block 42 to move away from the assembly square tube 1, so that the magnet 100 can be docked and bonded with the magnet 100 filled with glue;

[0098] (4): After the bonding is completed, the down-presser 3 is docked with the down-moving stabilizer 5, so that the multiple bonded magnets 100 located between the down-pressing plate 31 and the bottom support plate 21 are moved downward as a whole until the upper surface of the magnet 100 at the upper end of the assembly square tube 1 contacts the lower surface of the clamping block 42. At this time, the bottom support plate 21 is fixed to the side wall of the assembly square tube 1 again through the down-moving control member 53. At the same time, the down-presser 3 is undocking from the down-moving stabilizer 5, and the down-pressing plate 31 is returned to its initial position under the drive of the down-pressing mechanism. Then, steps (2) to (4) are repeated until the Halbach array magnet 100 is assembled.

[0099] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
