Description

Technical Field

[0001] The utility model relates to the technical field of Halbach magnet assembly equipment, in particular to a three-direction squeezing and aligning positioning device for Halbach magnetic components. Background Art

[0002] Due to its nearly ideal magnetic field performance, the Halbach magnet assembly is widely used in electronic products such as computers, communications, and consumer electronics. However, since the internal space of electronic products is generally limited, high precision requirements are imposed on the external dimensions of the magnetic assembly. Conventional Halbach magnet assemblies generally consist of three magnets. Usually, the three magnets are placed in the Halbach array pattern and then pasted and assembled. During this assembly process, the alignment and positioning of the three magnets are very important. Whether the alignment and pasting can be accurately performed will directly affect the external dimensions of the entire magnet assembly.

[0003] Currently, the commonly used method on the market is manual assembly and positioning through a right-angle tool. During operation, after applying glue between the magnets, the positioning of the magnetic assembly is achieved by squeezing with two right-angle toolings. This assembly method requires assembling the magnets one by one, resulting in low efficiency. Secondly, the manual assembly accuracy is related to each person's operation method, and there is a problem that the alignment and positioning accuracy cannot be guaranteed during assembly, which further affects the non-uniformity of the external dimensions of each assembled magnetic assembly. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a three-direction squeezing and aligning positioning device for Halbach magnetic components to solve the above technical problems of low manual assembly efficiency and low alignment and positioning accuracy.

[0005] To achieve the above object, the solution of the utility model is: a three-direction squeezing and aligning positioning device for Halbach magnetic components, used for assembling multiple magnets into a magnetic assembly, including a placement table, a first pusher, a second pusher, a third pusher, and a pressing head;

[0006] The top surface of the placement table is used to sequentially place multiple magnets along the horizontal first direction;

[0007] The first pusher and the second pusher are located on both horizontal sides of the placement table and can approach or move away horizontally. When approaching, the multiple magnets are clamped and brought closer along the first direction;

[0008] The second direction is in the horizontal plane and perpendicular to the first direction. Along the second direction, an alignment surface is formed on one side of the placement table. The third pusher is located above the placement table, and the third pusher can horizontally move along the second direction at one end of the multiple magnets on the placement table, so as to be able to push from one end of the multiple magnets, making the other end of the multiple magnets abut against the alignment surface;

[0009] The pressing head is used to apply pressure to the top surface of the multiple magnets placed.

[0010] Further, the number of placing platforms is multiple, and the multiple placing platforms are arranged at intervals in the second direction. Each placing platform is correspondingly provided with a first pusher head, a second pusher head, a third pusher head and a pressing head.

[0011] Further, the first pusher head is used to horizontally abut against the outer side surface of the magnet. When the first pusher head abuts against the outer side surface of the magnet, the second pusher head pushes multiple magnets towards the first pusher head, so that the multiple magnets are assembled into a magnetic component.

[0012] Further, magnetic attraction can be achieved between the pressing head and the magnet.

[0013] Further, it includes a second sliding plate which slides horizontally. A second installation groove is formed on the second sliding plate. A second push rod is slidably arranged in the second installation groove. The second pusher head is formed at the end of the second push rod and extends out of the second installation groove. A first elastic member is arranged between the inner end of the second push rod and the second installation groove, so as to drive the second pusher head to horizontally approach or move away from the placing platform when the second sliding plate slides horizontally.

[0014] Furthermore, the number of second push rods corresponding to one placing platform is two. The above-mentioned second pusher heads are formed at the ends of each second push rod. Each second push rod is connected with a first elastic member. The two second pusher heads respectively abut and push against both ends of the side surface of the magnet.

[0015] Further, the third pusher head can move up and down.

[0016] Furthermore, it also includes a lifting mechanism and a sliding seat. The lifting mechanism can move up and down. The sliding seat can slide horizontally. The sliding seat is installed on the lifting mechanism. A longitudinally extending sliding groove is formed on the sliding seat. A longitudinal push rod is slidably arranged in the sliding groove. The third pusher head is formed at the bottom end of the longitudinal push rod and extends downward out of the sliding seat. A second elastic member is arranged between the top end of the longitudinal push rod and the inner wall of the sliding groove, so as to drive the third pusher head to longitudinally approach or move away from the placing platform when the lifting mechanism moves up and down, and to drive the third pusher head to horizontally abut and push the magnetic component when the sliding seat slides horizontally.

[0017] Further, the first pusher head is formed with a first abutting surface and a first limiting surface. The first abutting surface protrudes from the first limiting surface. The first abutting surface is used to fit and abut against the outer side surface of the magnet. The first limiting surface is used to abut against the side surface of the placing platform to limit the movement of the first pusher head.

[0018] Further, it includes a first sliding plate which slides horizontally. The first pusher head is detachably installed on the first sliding plate, so as to drive the first pusher head to horizontally approach or move away from the placing platform when the first sliding plate slides horizontally.

[0019] After adopting the above solution, the beneficial effects of the present utility model are as follows: By clamping and bringing multiple magnets closer along the horizontal first direction with the first push head and the second push head, the assembly of multiple magnets in the first direction is realized. Then, by pushing from one end of the multiple magnets along the horizontal second direction with the third push head, the other end of the multiple magnets is abutted against the alignment surface, realizing the alignment and extrusion assembly of the multiple magnets in three directions, improving the alignment accuracy, realizing semi-automatic assembly, improving the assembly efficiency and the forming size accuracy of the magnetic component. In addition, by pressing and maintaining pressure on the top surface of the multiple magnets with the pressing head, the problem that the multiple magnets arranged in the Halbach pattern jump up can be prevented.

Detailed implementation mode

[0030] The following combines the accompanying drawings and specific embodiments to make a detailed description of the present utility model.

[0032] As Figures 1 to 8 shown, the present utility model provides a Halbach magnetic component three - direction alignment and positioning device for assembling multiple magnets 100 into a magnetic component 200, including a placement table 4, a first pusher head 1, a second pusher head 2, a third pusher head 3 and a pressing head 5;

[0033] The present alignment and positioning device includes a workbench 300, a jig 400 and a mounting frame 500. A placement table 4 is arranged on the top side of the jig 400. The top surface of the placement table 4 is used to sequentially place multiple magnets 100 along a horizontal first direction. A first pusher 1 and a second pusher 2 are arranged on the workbench 300. The first pusher 1 and the second pusher 2 are located on both horizontal sides of the placement table 4 and can approach or move away horizontally. When approaching, the multiple magnets 100 can be clamped and brought closer along the first direction. The mounting frame 500 is fixed on the workbench 300 and extends horizontally above the placement table 4. A third pusher 3 is arranged on the mounting frame 500, located above the placement table 4, and can move up and down and horizontally. A second direction is in the horizontal plane and perpendicular to the first direction. Along the second direction, an alignment surface 41 is formed on one side of the placement table 4. The third pusher 3 can horizontally move along the second direction at one end of the multiple magnets 100 on the placement table 4 and push from one end of the multiple magnets 100, so that the other end of the multiple magnets 100 abuts against the alignment surface 41, realizing the alignment and extrusion of the multiple magnets 100 in three directions. In this specific embodiment, there is no magnetic attraction between the first pusher 1, the second pusher 2 and the magnet 100. Specifically, it can be made of stainless steel material or aluminum alloy material, or other non-ferromagnetic materials.

[0034] Focusing on Figure 3 As shown, the multiple magnets 100 are placed at intervals and arranged in the Halbach array pattern. Due to the characteristics of the Halbach magnet, during assembly, the middle magnet will jump up due to the repulsive force. It includes a pressure head 5. The pressure head 5 is used to apply pressure on the top surface of the multiple magnets 100 to prevent the middle magnet 100 from jumping up. Specifically, there can be magnetic attraction between the pressure head 5 and the magnet 100, and the magnet 100 can be adsorbed on the pressure head 5 and slide. When in use, the multiple magnets 100 are arranged and placed on the bottom surface of the pressure head 5, and then the pressure head 5 adsorbed with the multiple magnets 100 is placed on the placement table 4. Further, along the second direction, the multiple magnets 100 protrude from the pressure head 5, so that when the third pusher 3 descends to the placement table 4, it can contact one end of the magnet 100.

[0035] Focusing on Figure 3 and Figure 4As shown, in order to improve the assembly efficiency and realize the simultaneous assembly of multiple groups of magnetic components 200, there are multiple placement tables 4, and the multiple placement tables 4 are arranged at intervals along the second direction. Each placement table 4 is correspondingly provided with a first push head 1, a second push head 2, a third push head 3 and a pressing head 5; specifically, a plurality of assembly stations 42 are arranged at intervals on the jig 400, and the plurality of assembly stations 42 are arranged at intervals along the second direction, and a placement table 4 is formed on each assembly station 42, and an alignment surface 41 is formed on one side of the assembly station 42, located on one side of the placement table 4 and away from the alignment surface 41, and an insertion position 43 for inserting the third push head 3 is also formed on the assembly station 42. Along the second direction, the length of the placement table 4 is less than the length of the magnet 100, so that when the magnet 100 is placed on the placement table 4, it can protrude from the side of the placement table 4, which is convenient for the third push head 3 to push the magnet 100 and reduce the processing accuracy of the jig 400.

[0036] In this specific embodiment, the first pusher head 1 is used to horizontally fit against the outer side of the magnet 100, focusing on the combination Figure 4 As shown, the first push head 1 is formed with a first abutting surface 11 and a first limiting surface 12, the first abutting surface 11 protrudes from the first limiting surface 12, the first abutting surface 11 is used to fit against the outer side of the magnet 100, and the first limiting surface 12 is used to abut against the side of the placement table 4 to limit the movement of the first push head 1 to prevent the first push head 1 from pushing the magnet 100 away from the placement table 4, so that when the first push head 1 fits against the outer side of the magnet 100, the second push head 2 pushes the multiple magnets 100 toward the first push head 1 with the first abutting surface 11 as a reference, so that the multiple magnets 100 are assembled into a magnetic assembly 200.

[0037] Focus on combination Figure 5 As shown, it includes a first slide plate 13, which slides horizontally, and a first push head 1 is detachably mounted on the first slide plate 13, so that when the first slide plate 13 slides horizontally, the first push head 1 is driven to horizontally approach or move away from the placement table 4; a first driving mechanism 14 is arranged on the workbench 300, and the first driving mechanism 14 is any existing linear driving mechanism, such as a telescopic cylinder or other, the first slide plate 13 is connected to the first driving mechanism 14, and the first driving mechanism 14 is used to drive the first slide plate 13 to slide horizontally and linearly, and a first mounting groove 15 is arranged on the first slide plate 13, and a first push rod 16 is installed in the first mounting groove 15, and the first push rod 16 is fixed in the first mounting groove 15 by bolts, and the first push head 1 extends out of the first mounting groove 15. Of course, other fixing methods can also be used, not limited to this, and it can be easily disassembled to replace the first push head 1.

[0038] Focus on combination Figure 6As shown, it includes a second slide plate 21 which slides horizontally. A second driving mechanism 24 is provided on the workbench 300. The second driving mechanism 24 is any existing linear driving mechanism, such as a telescopic cylinder or others. The second slide plate 21 is connected to the second driving mechanism 24. The second driving mechanism 24 is used to drive the second slide plate 21 to slide horizontally in a straight line. A second installation groove 22 is formed on the second slide plate 21. A second push rod 23 is slidably arranged in the second installation groove 22. A second push head 2 is formed at the end of the second push rod 23 and extends outside the second installation groove 22. Since multiple assembly stations 42 are assembling multiple groups of magnets 100 simultaneously, in order to ensure that each group of magnets 100 can be fully pushed and assembled, a first elastic member 6 is arranged between the inner end of the second push rod 23 and the second installation groove 22. When the second slide plate 21 slides horizontally, it drives multiple second push heads 2 to approach or move away from the placement table 4 horizontally. When the multiple second push heads 2 approach the magnet 100 horizontally, the setting of the first elastic member 6 can ensure that each second push head 2 can fully abut against the magnet 100. The first elastic member 6 is specifically a compression spring. Of course, it can also be a spring sheet or others, without specific limitation.

[0039] In order to further improve the stability of the horizontal pushing of the magnet 100, the number of second push rods 23 corresponding to each placement position 4 is two. The second push head 2 is formed at the end of each second push rod 23. Each second push rod 23 is connected to a first elastic member 6. The two second push heads 2 respectively abut and push against both ends of the side of the magnet 100, which can make the second push heads 2 fully fit against both ends of the side of the magnet 100, enable the magnet 100 to slide horizontally and evenly, and further ensure that multiple magnets 100 are fully fitted and assembled. The magnet 100 will not deflect during the abutting and pushing process. Of course, the number of second push rods 23 corresponding to each placement position 4 can also be three or others, not limited to this. Those skilled in the art can design according to specific situations.

[0040] Focus on combining Figure 8As shown in the figure, the third pusher 3 can move up and down, and can descend to one end of multiple magnets 100 on the placement table 4. It further includes a lifting mechanism 31 and a sliding seat 32. The lifting mechanism 31 is slidably arranged on the mounting frame 500 and moves up and down longitudinally. The lifting mechanism 31 is any existing linear driving mechanism, which can be a telescopic cylinder or others. The sliding seat 32 can slide horizontally and is installed on the lifting mechanism 31. Specifically, a third driving mechanism 34 is arranged between the sliding seat 32 and the lifting mechanism 31. The third driving mechanism 34 is connected to the sliding seat 32 to drive the sliding seat 32 to slide horizontally. The third driving mechanism 34 is any existing linear driving mechanism, which can be a telescopic cylinder or others. A longitudinally extending chute 33 is formed on the sliding seat 32. The third pusher 3 is longitudinally slidably arranged in the chute 33, and the bottom end of the third pusher 3 extends downward out of the sliding seat 32. When the lifting mechanism 31 moves up and down, the sliding seat 32 drives the third pusher 3 to longitudinally approach or move away from the placement table 4. When the sliding seat 32 slides horizontally, it drives the third pusher 3 to horizontally push against the magnetic component 200. Since there are multiple assembly stations 42 and multiple groups of magnetic components 200 need to be aligned simultaneously, in order to ensure that each group of magnetic components 200 can be fully aligned to the alignment surface 41, a second elastic member 7 is arranged between the top end of the third pusher 3 and the inner wall 3 of the chute 33, which can ensure that each third pusher 3 can descend to the corresponding insertion position 43 (as shown in Figure 7 the figure), so as to be able to push against the magnetic component 200 along the second direction to align the magnetic component 200.

[0041] During use, first place the pressing head 5 adsorbed with multiple magnets 100 on the placement position 4. The first driving mechanism 14 drives the first sliding plate 13 to drive the first pusher 1 to horizontally approach the placement table 4 until the first limiting surface 12 abuts against the side surface of the placement table 4. Then the second driving mechanism 24 drives the second sliding plate 21 to drive the second pusher 2 to horizontally approach the placement table 4 and push against multiple magnets 100 in the direction of the first pusher 1 until multiple magnets 100 are completely fitted and assembled. The second driving mechanism 24 drives the second pusher 2 to move away from the placement table 4. The lifting mechanism 31 descends, so that the sliding seat 32 drives the third pusher 3 to downwardly insert into the insertion position 43 of the assembly station 42. The third driving mechanism 34 drives the sliding seat 32 to drive the third pusher 3 to slide horizontally, and push against from one end of the magnetic component 200, so that the other end of the magnetic component 200 abuts against the alignment surface 41 for alignment. The second driving mechanism 24 drives the second pusher 2 to approach the placement table 4 again to horizontally push the magnetic component 200. Then the third driving mechanism 34 drives the sliding seat 32 to reset and move away from the magnetic component 200. The lifting mechanism 31 drives the sliding seat 32 to rise and reset. The second driving mechanism 24 resets, and the first driving mechanism 14 resets. The assembly is completed.

[0042] The above are only the preferred embodiments of the present invention, and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
