Description

Technical Field

[0001] This invention relates to the field of magnetization technology, specifically to a magnetization box and its manufacturing method. Background Technology

[0002] With the development of new energy technologies, magnetization is becoming increasingly common in the processing of new energy products and components. For example, during the manufacturing process of motor rotors, a magnetization device is used to magnetize the rotor to give it magnetic properties. Currently, magnetization is also being applied to new energy battery technology for magnetizing thin materials. To improve the magnetization efficiency of thin materials, methods such as... Figure 1 The strip magnetization method shown involves using a conveyor belt to magnetize the foil to be magnetized. The magnetizable foil is coated onto the strip, baked in a baking machine 2, and then magnetized by a strip magnetizer 1. Therefore, a magnetization mechanism needs to be installed inside the strip magnetizer 1. This mechanism has a magnet and a magnetic circuit design, enabling it to perform magnetization. Furthermore, the magnetization mechanism has a simple structure, facilitating installation. Summary of the Invention

[0003] In view of the above, it is necessary for the present invention to provide a magnetizing box that is simple and novel in structure, easy to process, and easy to install into a magnetizer.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A magnetizing box includes a base, several magnetizing components, a retaining wall, and several pressure strips. The magnetizing components are arranged side by side on the base. Each magnetizing component includes two magnetic columns and a magnetic strip disposed between the two magnetic columns. Each magnetic column includes several magnets arranged linearly. Adjacent magnets are in contact but repel each other magnetically. The retaining wall is fixed on the base to form an outer cavity for accommodating the several magnetizing components and restricts the magnets of the magnetizing components from moving to the sides or ends. The pressure strips press against the top of the magnetizing components and restrict the magnets of each magnetic column from moving upward.

[0006] In addition, the present invention needs to provide a method for manufacturing the aforementioned magnetizing box, the method comprising:

[0007] A magnetizing assembly device is provided, including a clamping base, a guide, a top support structure, a pushing mechanism, and a locking mechanism;

[0008] The base of the magnetizing box is placed horizontally on the clamping seat and locked in place by the locking mechanism. The pushing mechanism pushes the magnetic segment onto the protrusion of the base.

[0009] When pushing the magnetic segment, guides are installed on both sides of the clamping seat to guide the magnetic segment. One of the guides on one side also presses and limits the magnetic segment. When fixing the magnetic segment after it is pushed into place, the top abutment structure set at the top of the clamping seat presses against one side of the top surface of the magnetic segment. A pressure strip is installed on the top surface of the magnetic segment to press against the other side of the top surface of the magnetic segment, and the pressure strip is fixed to the clamping seat.

[0010] The locking mechanism unlocks and moves the base until it aligns with the next magnetic segment in the same column, then locks in place. Similarly, the next magnetic segment is installed.

[0011] In this way, the base moves segment by segment to allow the magnetic segments to be installed segment by segment, so that several magnetic segments are connected to form a magnetic array;

[0012] After completing the installation of one magnetic column, proceed to the installation of the next magnetic column. The assembly process is the same as the previous column, until all magnetic columns are installed.

[0013] The beneficial effects of this invention are as follows:

[0014] The magnetizing box provided by this invention is a novel magnetizing product designed for use in magnetizing equipment to magnetize foil coatings applied to strips. Several magnetizing components are arranged in parallel within the box, each with two magnetic columns and a magnetic strip between them, fully meeting the required magnetic field strength. These components are mounted on a raised platform on the base and secured by surrounding walls and a pressure strip above the platform. This ensures the magnetizing components are stably mounted on the base and will not move due to repulsive forces between adjacent magnets, guaranteeing the stability and durability of the magnetizing box.

Detailed Implementation

[0036] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0037] This invention provides a magnetizing box 10 for installation in a magnetizer, enabling the magnetizer to perform magnetization. Preferably, the magnetizing box 10 provided by this invention is used in the magnetization mechanism of a strip magnetizer, such as... Figure 2 As shown, the magnetization mechanism includes an adjustment base 4 and a magnetization box 10 mounted on the adjustment base 4. The adjustment base 4 can adjust the height, levelness, and offset of the magnetization box 10 from one end to the other on the horizontal plane. The specific structure of the adjustment base 4 will not be described in this invention.

[0038] Please see Figures 3-5 The magnetizing box 10 includes a base 11, several magnetizing components 12 arranged side by side on the base 11, a surrounding wall 13 fixed around the base 11, and several pressure strips 14 pressing against the top of the magnetizing components 12. The base 11, the surrounding wall 13, and the pressure strips 14 are all made of non-magnetic materials, such as aluminum. The surrounding wall 13 forms an outer cavity to accommodate the several magnetizing components 12 and restricts the magnetizing components 12 from moving to the sides or ends. The pressure strips 14 restrict the magnetizing components 12 from moving upward.

[0039] The base 11 includes a base plate 111 and a boss 112 protruding from the base plate 111. Correspondingly, a stepped surface 1111 is formed on both sides and both ends of the boss 112 on the upper surface of the base plate 111. A fixing hole 1112 is provided on the stepped surface 1111 for fixing the enclosure wall 13.

[0040] A plurality of magnetically conductive grooves 1121 are parallel to each other on the top surface of the boss 112. The magnetically conductive grooves 1121 extend from one end of the boss 112 to the other end, passing through both ends of the boss 112. Each magnetically conductive groove 1121 is used to cooperate with a magnetizing component 12 for installation. In this embodiment, the base 11 is a rectangular strip plate, and the boss 112 is a corresponding rectangular strip block. The magnetically conductive grooves 1121 extend along the length direction of the boss 112 and pass through both ends of the boss 112.

[0041] Several magnetizing components 12 are mounted in parallel on the top surface of the boss 112. Each magnetizing component 12 includes two magnetic columns 121 and a magnetic strip 122 disposed between the two magnetic columns 121. Each magnetic column 121 includes several magnetic segments, which are formed by the linear arrangement of the magnetic segments end to end, and adjacent magnetic segments repel each other at the connection point. Each magnetic segment includes several magnets, which are formed by the linear arrangement of the magnets end to end, and adjacent magnets repel each other at the connection surface. The magnetic segments are formed by applying strong adhesive to the connection surface of adjacent magnets. Understandably, the adhesive weakens as the adhesive ages over time and can only maintain a limited bonding time. Otherwise, after a certain period of time, the magnets will split due to the repulsive force. Therefore, the magnetic segments need to be assembled in a timely manner after formation.

[0042] The magnetic strip 122 is provided to enhance the overall strength of the magnetic field, as required by the magnetic circuit design. The magnetic strip 122 is fixedly installed within the magnetic groove 1121. Specifically, the lower end of the magnetic strip 122 is fixedly fitted within the magnetic groove 1121, and its upper end is clamped between two magnetic columns 121, tightly adhering to them. The two magnetic columns 121 repel each other magnetically. The magnetic strip 122 is made of a magnetic material, attracting the magnetic columns 121 on both sides. Preferably, the magnetic strip 122 is made of ferrous material, such as an iron sheet. Furthermore, to improve the installation stability of the magnetic strip 122, the magnetic groove 1121 preferably has an inverted T-shaped cross-section. Correspondingly, the magnetic strip 122 is also inverted T-shaped, and after installation, its upper end extends out of the magnetic groove 1121, clamping between the two magnetic columns 121 mounted on the top surface of the boss 112.

[0043] The enclosure wall 13 is used to enclose a plurality of magnetizing components 12 arranged side by side on the base 11. In this embodiment, the enclosure wall 13 includes a side wall 131 and an end wall 132. The side wall 131 is mounted on the stepped surfaces 1111 on both sides of the boss 112 on the upper surface of the base plate 111, and the end wall 132 is mounted on the stepped surfaces 1111 at both ends of the boss 112 on the upper surface of the base plate 111. Both the side wall 131 and the end wall 132 exceed the top surface of the boss 112 by a preset height, roughly corresponding to the height of the magnet. The side wall 131, the end wall 132 and the base plate 111 are preferably connected by screw fastening. The side wall 131 abuts against the side of the corresponding outermost magnetic array 121, and the end wall 132 abuts against the end face of the magnetic array 121 to prevent the magnets on both sides or at both ends from moving outward.

[0044] In this embodiment, in conjunction with the manufacturing method of the magnetizing box, among the two side walls 131, the rear side wall 131 (which can be regarded as the rear side wall) is a whole wall, and the front side wall 131 (which can be regarded as the front side wall) is formed by several wall segments arranged in a straight line.

[0045] Several pressure strips 14 are used to press against the top surface of the corresponding magnetic array 121 to prevent the magnets of the magnetic array 121 from moving upwards. The pressure strips 14 can be locked to the side wall 131, the end wall 132, or locked above the top surface of the boss 112 by long screws to achieve downward pressing against the magnetic array 121. In this embodiment, combined with the manufacturing method of the magnetizing box, each pressure strip 14 is formed by several pressure strip segments 141 arranged linearly, and the length of each pressure strip segment 141 corresponds to the length of the magnetic segment, so as to press against one side of the top surface of the corresponding magnetic segment. In order to improve the pressing stability, the pressing contact surface between the pressure strip segment 141 and the magnetic segment adopts a wedge-shaped surface. Furthermore, the wedge-shaped surface of the top surface of the magnetic segment is formed on the side opposite to the magnetic guide strip 122, so that after the pressure strip segment 141 presses down on the magnetic segment, it has a force to hold the magnetic segment against the magnetic guide strip 122, ensuring stable contact between the magnetic segment and the magnetic guide strip 122.

[0046] In this embodiment, the pressure strip segment 141 is locked to the side wall 131 or the top surface of the boss 112 to press against the magnetic array 121. The pressure strip segment 141 fixed to the side wall 131 can be regarded as an edge pressure strip segment, with a wedge-shaped surface on one side of its bottom surface for engagement with the magnetic array on the side. The pressure strip segment 141 fixed to the top surface of the boss 112 can be regarded as an inner pressure strip segment, with wedge-shaped surfaces symmetrically provided on both sides of its bottom surface for pressing against the magnetic arrays of the two adjacent magnetizing components 12. Understandably, the inner pressure strip segment can be fixed to the top surface of the boss 112 by using a long screw, that is, a screw hole is opened on the top surface of the boss 112, and the screw passes through the inner pressure strip segment and screws into the screw hole of the boss 112, without the bottom surface of the inner pressure strip segment contacting the top surface of the boss 112. Thus, multiple magnetizing components 12 are arranged side by side on the boss 112, and the magnetic columns of adjacent magnetizing components 12 can be pressed against each other by the inner pressure strips; for magnetizing components 12 arranged on both sides of the boss 112, the magnetic columns on the edge of the magnetizing component 12 are pressed against each other by the edge pressure strips.

[0047] Furthermore, the magnetizing box 10 includes a cover 15 for covering the top surface of the base 11 and sealing the magnetizing assembly 12, the enclosure wall 13, and the pressure strip 14 on the base 11.

[0048] The magnetizing box 10 provided by this invention has a simple overall structure and a compact arrangement of magnetizing components 12. Designed according to the magnetic field and magnetic circuit required by the magnetizer, it can fully meet the magnetization requirements of the strip material when installed on the magnetizer. Specifically, by arranging a plurality of magnetizing components 12 in parallel within the magnetizing box 10, each magnetizing component 12 has two magnetic columns 121 and a magnetic guide strip 122 disposed between the two magnetic columns 121, fully meeting the requirements for magnetic field strength. The magnetizing components 12 are disposed on the protrusions 112 of the base 11 and are limited and fixed by the surrounding walls 13 and the pressure strip 14 above the protrusions. The magnetizing components 12 can be stably installed on the base 11 and will not move due to the repulsive force between adjacent magnets, ensuring the stability and durability of the magnetizing box 10.

[0049] Those skilled in the art will foresee that, in manufacturing the magnetizing box 10, due to the repulsive magnetic force between the magnets, it is not easy to complete the manufacturing process by hand. Correspondingly, this invention provides a method for manufacturing the magnetizing box 10, which can overcome the repulsive force between the magnets for arrangement and fixation, greatly improving manufacturing efficiency.

[0050] Please see Figures 6-10The present invention also provides a magnetic box assembly device for manufacturing a magnetizing box 10, including a clamping base 20, guide members 30, a top abutment structure 40, a pushing mechanism 50, and a locking mechanism 60. The clamping base 20 includes clamping walls 21 arranged opposite to each other, forming a pushing channel 211 between the two clamping walls 21. One end of the pushing channel 211 is connected to the pushing mechanism 50, and the other end is equipped with the locking mechanism 60. The two clamping walls 21 are provided with through holes 212 opposite to each other, so that the base 11 of the magnetizing box 10 can pass through the clamping base 20. The inserted base 11 is perpendicular to the pushing channel 211. There are several guide members 30 of different lengths, which are used to selectively install in the through holes 212 of the two clamping walls 21 when installing magnetic segments, to guide the pushed magnetic segments and to guide the magnetic segments. The end abutment limit is provided. The abutment structure 40 is installed on the top surface of the clamping seat 20, forming the top wall of the push channel 211. It is used to press against the top surface of the magnetic segment during installation, pressing one side of the top surface of the magnetic segment, so that the pressing strip 141 can press against the other side of the top surface of the magnetic segment. The push mechanism 50 is used to push the magnetic segment along the push channel to the top surface of the boss 112 of the base 11. The locking mechanism 60 is used to lock the base 11 into the clamping seat 20 so that the magnetic segment can be installed at the corresponding position on the top surface of the boss 112 of the base 11. After unlocking, the base 11 is moved a preset distance and then locked again to install the next magnetic segment. By moving the base 11 relative to the clamping seat 20 segment by segment and installing the magnetic segments, the magnetic segments are installed in a row on the base 11.

[0051] Specifically, the clamping seat 20 includes a base plate 22 and clamping walls 21 formed on both sides of the base plate 22. A horizontal bar 221 is fixedly connected to one end of the push channel 211 of the base plate 22. The horizontal bar 221 extends along the length direction perpendicular to the base plate 22, and its two ends are connected to the clamping walls 21. The thickness of the horizontal bar 221 is approximately the same as the thickness of the base plate 111. A protrusion 2211 is formed on the side of the horizontal bar 221, which, after the base 11 is inserted into the clamping seat 20, engages with a recessed hole on one side of the base plate 111 to limit the lateral movement of the base 11 relative to the clamping seat 20. A connecting plate 222 is mounted on the top surface of the horizontal bar 221. The connecting plate 222 is used to fix the push mechanism 50. The thickness of the connecting plate 222 is approximately the same as the thickness of the protrusion 112. Preferably, in order to improve the stability of the connecting plate 222, two horizontal bars 221 are installed in the push channel 211 for fixing the connecting plate 222.

[0052] The two clamping walls 21 can be divided into a left clamping wall and a right clamping wall. The width of the push channel 211 between the clamping walls 21 corresponds to the length of the magnetic segment, so that the magnetic segment can be placed horizontally in the push channel 211 during installation. That is, when the magnetic segment is pushed, the two ends of the magnetic segment abut against the plate surface of the clamping wall 21 respectively.

[0053] There are multiple guide members 30 of different lengths, which are selectively installed in the through holes 212 of the two clamping walls 21. Depending on whether they are installed on the corresponding left or right clamping walls, they can be divided into left guide members and right guide members. They play a role in guiding the magnetic segment when it passes through the through hole 212 of the clamping wall 21. The right guide member also plays a role in preventing the magnetic segment being installed from moving laterally under the repulsive force of the end face of the previously installed magnetic segment after the previous magnetic segment has slid into place. That is, the right guide member supports the end of the newly installed magnetic segment.

[0054] Specifically, such as Figure 7 As shown, the guide member 30 includes an insert 31 and a fixing plate 32. The insert 31 is inserted into the through hole 212, and its thickness is similar to that of the clamping wall 21. It has a guide surface, and after being inserted into the through hole 212, its guide surface is flush with the inner surface of the clamping wall 21. The insert 31 is located at the upper end of the through hole 212, and the lower end of the through hole 212 is for the base 11 to pass through. Specifically, the bottom end of the insert 31 is approximately in contact with the top surface of the boss 112. The fixing plate 32 is used to fix it to the clamping wall 21. The insert 31 is fixedly mounted on the fixing plate 32. After the insert 31 is inserted into the through hole 212, the insert 31 is stably installed in the through hole 212 by locking the fixing plate 32 to the clamping wall 21.

[0055] As each magnetic column is installed, the length of the guide 30 used for the magnetic column varies from far to near. Specifically, the guide 30 embedded in the insert 31 required when installing the magnetic column far from the pushing mechanism 50 is longer, while the guide 30 embedded in the insert 31 required when installing the magnetic column close to the pushing mechanism 50 is shorter. Thus, different guides 30 need to be replaced as each magnetic column is installed.

[0056] When installing the same magnetic array, the lengths of the embedded bodies 31 in the through holes 212 of the two clamping walls 21 are also different. Specifically, after the previous magnetic segment has been installed, when installing the next magnetic segment, the end of the embedded body 31 on one side will abut against the front surface of the previous magnetic segment, while the length of the embedded body 31 on the other side will be approximately longer than the thickness of a magnet, so as to hold the next magnetic segment and restrict its lateral movement.

[0057] The top abutment structure 40 includes a top abutment bar 41 and a movable plate 42. Both ends of the top abutment bar 41 and the movable plate 42 are connected to the two clamping walls 21. There are several top abutment bars 41, corresponding to the number of magnetic columns. Each top abutment bar is set above the corresponding magnetic column and is used to abut against one side of the magnetic column. Each top abutment bar 41 is equipped with a lifting screw 411, which is used to rotate downward to press against the corresponding magnetic segment and tighten the magnetic segment. The movable plate 42 is above the pressure bar 14 that presses against each magnetic column and can be lifted off the clamping seat 20 for installing the pressure bar segment 141.

[0058] The pushing mechanism 50 includes a support base 51, a guide assembly 52, a drive assembly 53, and a pushing assembly 54. The pushing assembly 54 is moved by the drive assembly 53, and the guide assembly 52 guides the movement of the pushing assembly 54. The support base 51 includes a support foot 511 and a support plate 512 mounted on the support foot 511. One end of the support plate 512 is connected to the connecting plate 222, and after the connection, the surface of the support plate 512 is flush with the surface of the connecting plate 222. The guide assembly 52 includes two end blocks 521 and two guide rods 522. The two end blocks 521 are fixed at both ends of the support plate 512, and the guide rods 522 are fixedly connected between the two end blocks 521. The drive assembly 53 includes a motor 531 and a bearing seat 53. 2. The lead screw 533 and the slider 534 are mounted on the end block 521. The output shaft of the motor 531 is connected to the lead screw 533 through the bearing seat 532, which drives the lead screw 533 to rotate. The slider 534 is sleeved on the lead screw 533 and is threadedly engaged with the lead screw 533. The rotation of the lead screw 533 drives the slider 534 to move axially along the lead screw 533. The slider 534 is slidably sleeved on the guide rod 522, which guides the slider 534 to move stably. The push assembly 54 includes a push plate 541 and a slide rod 542. The width of the push plate 541 corresponds to the length of the magnetic segment, and it is used to push the magnetic segment from the surface of the support plate 512 into the surface of the connecting plate 222 and then slide along the push channel 211. The push plate 541 is connected to one end of the slide rod 542, and the other end of the slide rod 542 passes through the end block 521 and is fixed to the slider 534. Thus, the push plate 541 is moved by the movement of the slider 534. Preferably, there are two guide rods 522 and two slide rods 542.

[0059] The locking mechanism 60 is installed in the push channel 211, at one end relative to the push component 54, and is used to lock the base 11 in place with the protrusion 2211 on the side of the horizontal bar 221. The locking mechanism 60 locks the other side of the base 11. The locking mechanism 60 includes a sliding plate 61, a mounting plate 62, and a push bolt 63. The sliding plate 61 is slidably installed in the push channel 211. A threaded hole is formed on one side of the sliding plate 61, and a protrusion 611 is formed on the other side. The mounting plate 62 is horizontally mounted on the base plate 22 and has a locking groove 621. One end of the push bolt 63 is rotatably locked in the locking groove 621, and the other end is screwed into the threaded hole of the sliding plate 63. Thus, the locking groove 621 holds the push bolt 63 in place on the mounting plate 62, preventing it from moving forward or backward. When the push bolt 63 is rotated, the sliding plate 61 slides, and the protrusion 611 of the sliding plate 61 slides into the hole on the other side of the base 11, thus securing the base 11. To release the locking mechanism, simply rotate the push bolt 63, causing the sliding plate 61 to move back. Furthermore, the positioning mechanism 60 includes a guide assembly for guiding the sliding displacement of the sliding plate 61. The guide assembly adopts a structure in which a guide groove and a guide post cooperate. For example, a guide groove 612 is opened on the sliding plate 61, and a guide post (not shown) protrudes from the base plate 22 and enters the guide groove 612 to realize the sliding guidance of the sliding plate 61.

[0060] Please see Figures 11-19 The method for manufacturing the magnetizing box 10 using the magnetic box assembly device is as follows:

[0061] In this embodiment, two sets of magnetizing components 12 are installed inside the magnetizing box 10. These two sets of magnetizing components 12 can be divided into a first magnetizing component and a second magnetizing component, each having four magnetic columns, which can be sequentially considered as the first magnetic column, the second magnetic column, the third magnetic column, and the fourth magnetic column. The first magnetizing component includes a first magnetic strip and a second magnetic strip, and the magnetic strip on the first magnetizing component can be considered as the first magnetic strip. The second magnetizing component includes a third magnetic strip and a fourth magnetic strip, and the magnetic strip on the second magnetizing component can be considered as the second magnetic strip. The first and second magnetizing components are installed sequentially, with the first magnetizing component located away from the pushing mechanism 50 and the second magnetizing component located closer to the pushing mechanism 50.

[0062] Correspondingly, the top surface of the boss 112 of the base 11 is provided with a first magnetic groove and a second magnetic groove, wherein the first magnetic groove is used to install the first magnetic strip and the second magnetic groove is used to install the second magnetic strip.

[0063] Before installation, spacers 70 are inserted into the two magnetic grooves 1121 of the boss 112. The first spacer is inserted into the first magnetic groove, and the second spacer is inserted into the second magnetic groove. After insertion, the top surface of the spacer 70 is flush with the top surface of the boss 112, so that the top surface of the boss 112 is flat, which makes the magnetic segment slide smoothly on the top surface of the boss 112. Otherwise, the magnetic segment will not be able to slide through due to the presence of the magnetic groove and may be blocked by the magnetic groove 1121. The length of the spacer 70 is greater than the length of the magnetic groove 1121, and one end of it extends out of the magnetic groove 1121 to facilitate removal.

[0064] In this embodiment, each magnetic column is formed by five magnetic segments arranged in a straight line. Thus, the installation of each magnetic column requires the base 11 to move horizontally five times relative to the clamping seat 20 so that the five magnetic segments are connected end to end. The movement of the base 11 can be regarded as the first segment, the second segment, the third segment, the fourth segment, and the last segment. Each magnetic column is installed sequentially from left to right.

[0065] Correspondingly, the top abutment structure 40 has four top abutment bars 41 arranged side by side for the four magnetic columns. Each top abutment bar 41 is used to press down on the top of the magnetic segment of each magnetic column when installing each magnetic column, preventing the magnet from arching upwards. Specifically, the top abutment bar 41 only presses down on one side of the top surface of each magnetic segment, which also serves the purpose of pressing down. The four top abutment bars 41 correspond to the positions of the first to fourth magnetic columns of the magnetization box 10, and can be regarded as the first top abutment bar, the second top abutment bar, the third top abutment bar, and the fourth top abutment bar, respectively.

[0066] First, begin the installation of the first magnetic array, that is, begin the installation of the first set of magnetization components 12;

[0067] The base 11 is passed horizontally through the through hole 212 through the clamping seat 20 until the first section of the base 11 corresponds to the push channel 211. Then the locking mechanism 60 locks it in place, so that the base 11 is clamped between the sliding plate 61 and the crossbar 221 of the locking mechanism 60, and the top surface of the connecting plate 222 is flush with the top surface of the boss 112. In addition, before the base 11 is inserted into the clamping seat 20, the rear side wall 131 (rear side wall) of the base 11 is first fixed to the base plate 111, and the left end wall 132 (left end wall) and the right end wall 132 (right end wall) of the base 11 are first fixed to the base plate 111.

[0068] When the first section of the base 11 is opposite to the push channel 211, the guide 30 (i.e., the left guide) is not installed in the through hole of the left clamping wall of the clamping seat 20. The left end wall of the base 11 is completely accommodated in the through hole 212 of the left clamping wall, filling the through hole 212. The inner side of the left clamping wall of the clamping seat 20 is flush with the inner side of the left end wall. In addition, the guide 30 (i.e., the right guide) is installed in the through hole 212 of the right clamping wall of the clamping seat 20. At this time, the embedding body 31 of the right guide is the longest in the longitudinal direction, which is equivalent to the longitudinal length of the entire through hole, and plays a role in guiding and supporting the magnetic segment.

[0069] The pushing mechanism 50 pushes the first magnetic segment of the first magnetic column onto the protrusion 112 of the base 11. The two ends of the first magnetic segment slide along the left end wall of the base 11 and the right guide of the clamping seat 20 until they abut against the rear side wall of the base 11. At this time, the two ends of the magnetic segment abut against the left end wall of the base 11 and the right guide of the clamping seat 20. The top of the magnetic segment is aligned with the first top abutment bar and pressed against it. The first top abutment bar only presses against one side (rear side) of the top surface of the magnetic segment.

[0070] Then, the movable plate 42 corresponding to the magnetic segment is lifted, exposing the other side (front side) of the top surface of the magnetic segment corresponding to the first magnetic column. Then, the pressure strip 141 is provided and locked to the rear side wall. The pressure strip 141 presses down and locks the magnetic segment. Under the pressure of the pressure strip 141, the right end of the magnetic segment will not move to the right.

[0071] Next, unlock the locking mechanism 60, move the base 11 (to the left) to the position where its second segment corresponds to the push channel 211, and then lock the locking mechanism 60. When the second segment of the base 11 is opposite to the push channel 211, the left end wall of the base 11 has moved out of the through hole 212 of the left clamping wall of the clamping seat 20. The left guide needs to be installed in the through hole 212 of the left clamping wall of the clamping seat 20, and the length of the insert 31 of the left guide needs to extend to the front side of the first magnetic segment that has been installed. The guide surface of the insert 31 of the left guide is flush with the end face of the first magnetic segment. At this time, the right guide installed in the through hole 212 of the right clamping wall corresponds to the installation of different magnetic segments of the same magnetic column and does not need to be replaced.

[0072] The pushing mechanism 50 pushes the second magnetic segment of the first magnetic column onto the protrusion 112 of the base 11. Before pushing the second magnetic segment, the movable plate 42 of the top abutment structure 40 is sealed on the clamping seat 20 to have a pressing effect. The two ends of the second magnetic segment slide along the left guide on the base 11 and the right guide on the clamping seat 20 until they abut against the rear side wall on the base 11. At this time, the top side of the magnetic segment is aligned with the first top abutment bar and presses against it.

[0073] Similarly, by lifting the movable plate 42 corresponding to the magnetic column, the other side of the top surface of the second magnetic segment corresponding to the first magnetic column is exposed. Then, a pressure strip 141 is provided and locked to the rear side wall. The pressure strip 141 presses down and locks the second magnetic segment.

[0074] This process continues until the tail section of the first magnetic column (i.e., the fifth magnetic segment) is locked by the pressure strip section 141; understandably, when installing the tail section, the guide 30 (i.e., the right guide) is not installed in the through hole of the right clamping wall of the clamping seat 20, and the right end wall of the base 11 is completely accommodated in the through hole 212 of the right clamping wall.

[0075] Next, the first pad of the first magnetic groove is removed, and then the first magnetic strip is pushed into the first magnetic groove. The length of the first magnetic strip corresponds to the length of the magnetic column, and the top of the first magnetic strip is flush with the top surface of the first magnet.

[0076] Then, the installation of the second magnetic column begins, which is also divided into five magnetic segments and installed sequentially.

[0077] Move the base 11 so that its first section aligns with the push channel 211. When installing the second magnetic column, the installation principle of the guide 30 in the through holes 212 of the two clamping walls 21 of the clamping seat 20 is the same as that of the first magnetic column. Similarly, when installing the first (leftmost) magnetic section, the guide 30 does not need to be installed in the through hole 212 of the left clamping wall to accommodate the left end wall of the base 11. When installing the second magnetic section, the guide 30 is installed in the through hole 212 of the left clamping wall. The guide 30 is installed in the through hole 212 of the right clamping wall from the first to the fourth magnetic column. The section is always equipped with a guide member 30. Since it needs to abut against the magnet on the right side, the longitudinal length of the insert 31 of the right guide member is longer than that of the insert 31 of the left guide member. Only when installing the fifth magnetic section is the guide member 30 in the through hole 212 of the right clamping wall removed to accommodate the right end wall of the base 11. Similarly, when each magnetic section abuts against the first magnetic strip, the corresponding movable plate 42 is lifted to expose one side of the top surface of the magnetic section (the other side is pressed by the corresponding second top abutment strip), and then the corresponding pressure strip section 141 is installed. When installing the pressure strip section 141, the pressure strip section 141 is pressed against one side of the magnetic section, and then a long bolt is passed through the pressure strip section 141, and the bottom end of the bolt is fixed to the boss 112. The bottom surface of the middle pressure strip 141 has symmetrically arranged wedge-shaped surfaces on both sides. One side (rear side) of the wedge-shaped surface presses against the top surface of the magnetic segment of the second magnetic column, while the other side (front side) of the wedge-shaped surface is used to press against the top surface of the magnetic segment of the third magnetic column.

[0078] Then, the installation of the third magnetic column begins, that is, the installation of the second group of magnetizing components 12, which is also divided into five magnetic segments and installed sequentially.

[0079] Similarly, the installation of the third magnetic column is based on the same principle as the first and second magnetic columns. The base 11 is moved and installed segment by segment from the first to the fifth. The guide 30 of the corresponding length is installed into the through hole 212 of the left and right clamping walls. When installing the first (leftmost) magnetic segment, the guide 30 does not need to be installed in the through hole 212 of the left clamping wall to accommodate the left end wall of the base 11. When installing the fifth magnetic segment, the guide 30 in the through hole 212 of the right clamping wall is removed (i.e., the guide 30 does not need to be installed in the through hole 221 of the right clamping wall) to accommodate the right end wall of the base 11. After each magnetic segment is pushed, it abuts against the middle pressure strip segment 141 and the wedge-shaped surface of the pressure strip segment 141 (front side), and is pressed by the corresponding pressure strip segment 141. Since the magnetic segment has been pressed down by the pressure strip segment 141, it is not necessary to lift the corresponding movable plate 42 to install the pressure strip segment 141 during the installation of the magnetic array.

[0080] Next, remove the second pad from the second magnetic groove, and then push the second magnetic strip into the second magnetic groove. Similarly, the length of the second magnetic strip corresponds to the length of the magnetic column, and the top of the second magnetic strip is flush with the top surface of the magnet.

[0081] Then, the installation of the fourth magnetic column begins. The installation process for the fourth magnetic column is the same as that for the first three magnetic columns. The base 11 is moved, and the columns are installed one by one from the first segment to the fifth segment. Since the fourth magnetic column is the first magnetic column, the magnetic segments have already filled the through holes 212. Therefore, during the installation of the first to the fifth magnetic segments of the fourth magnetic column, guides cannot be installed in the through holes of the left clamping wall. Only during the installation of the first to the fourth magnetic segments in the through holes 212 of the right clamping wall, guides need to be installed to hold the ends of the magnetic segments. When installing the fifth magnetic segment, the guides in the through holes 212 of the right clamping wall are removed, and the through holes accommodate the right end wall of the base 11, which holds the end of the fifth magnetic segment. During installation, each magnetic segment of the fourth magnetic column has its top surface on one side (rear side) pressed against by the fourth pressure strip 14. In this way, the movable plate 42 corresponding to the fourth magnetic column can be lifted, the wall segment of the front side wall can be locked to the bottom plate 111 first, and then the corresponding pressure strip segment 141 can be locked on the wall segment to press against the corresponding magnetic segment.

[0082] Thus, the installation of the four magnetic columns on the base 11 is completed, that is, the installation of the two sets of magnetizing components 12. It can be understood that no matter how many sets of magnetizing components 12 are installed, the above installation principle can be used for installation.

[0083] Then, pull out the clamping seat 20 from the base 11 and seal the box cover 15 on the base 11 to complete the production of the magnetizing box.

[0084] From the above installation method, we can summarize that: first, the outlines of the three sides of the boss 112, namely the rear side wall, left end wall, and right end wall, are installed on the base 11; then, the base 11 is pushed onto the clamping seat 20, and according to the number of magnetic segments in each magnetic column, the base 11 is moved segment by segment to align with the pushing channel 211 so that the magnetic segments can be pushed into the corresponding positions on the boss 112; when pushing in each magnetic segment, guide members 30 are selectively installed in the through holes 212 on the two clamping walls of the clamping seat to guide the magnetic segment, and one side of the guide... The component 30 presses and limits the magnetic segment; after each magnetic segment is aligned, the corresponding top abutment strip 41 presses against one side of the magnetic segment, and the movable plate 42 is lifted to allow the locking strip segment 141 to press against the other side of the magnetic segment; during the alignment of each magnetic column, the length of the guide component 30 in the through hole 212 on the two clamping walls of the clamping seat is matched accordingly. When installing the last column of magnetic columns, after each magnetic segment is installed, the wall segment of the front side wall and the pressing strip segment 141 are installed on the base 11 accordingly until the front side wall segment and the pressing strip segment 141 are completely installed.

[0085] Specifically, the main steps in the production process include:

[0086] 1) A magnetizing assembly device is provided, which includes a clamping seat 20, a guide 30, a top abutment structure 40, a pushing mechanism 50, and a locking mechanism 60. The clamping seat 20 has a clamping wall 21 and forms a pushing channel 211. One end of the pushing channel 211 is connected to the pushing mechanism 50, and the other end is equipped with the locking mechanism 60. Through holes 212 are opened on the clamping wall 21 so that the base 11 of the magnetizing box 10 passes through the clamping seat 20 and is perpendicular to the pushing channel 211. The top abutment structure 40 includes a plurality of top abutment strips 41 for correspondingly pressing against the top half of the magnet array. There are a plurality of guides 30 with different lengths for selectively installing onto the through holes 212 of the two clamping walls 21.

[0087] 2) The base 11 of the magnetizing box 10 is passed horizontally through the clamping seat 20 and locked by the locking mechanism 60. The pushing mechanism 50 pushes the magnetic segment onto the protrusion 112 of the base 11.

[0088] When pushing the magnetic segment, a guide 30 is installed in the through hole 212 of the clamping wall 21 to guide the magnetic segment. One side of the guide 30 presses and limits the magnetic segment. When fixing the magnetic segment after it is pushed into place, the top abutment strip 41 corresponding to the top of the clamping seat 20 presses against one side of the top surface of the magnetic segment. A pressure strip 141 is installed on the top surface of the magnetic segment to press against the other side of the top surface of the magnetic segment, and the pressure strip 141 is fixed to the clamping seat 20.

[0089] The locking mechanism 60 unlocks the movable base 11 and locks it in place after aligning with the next magnetic segment in the same column. Similarly, the next magnetic segment is installed.

[0090] Thus, the base 11 moves segment by segment to be aligned with the corresponding magnetic segment, so that the magnetic segments can be installed segment by segment, and several magnetic segments are connected to form a magnetic array 121;

[0091] 3) After completing the installation of one magnetic column 121, proceed to the installation of the next magnetic column 121. Repeat the above process 2) until several magnetic columns 121 are completely installed.

[0092] In summary, the method for manufacturing a magnetizing box according to the present invention, by using the aforementioned magnetizing box assembly device, can effectively overcome the repulsive force between magnetic segments, accurately and quickly install the magnetic segments, and stably limit the position of the installed magnetic segments, thus avoiding the possibility of breakage between magnets due to repulsive force.

[0093] The embodiments described above merely illustrate implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
