Description

Technical Field

[0001] This utility model relates to the field of magnet assembly technology, and in particular to an assembly fixture for irregularly shaped three-piece Helbeck magnet components. Background Technology

[0002] Magnet components are typically designed as ring structures for use in mobile phones or phone stands as magnetic positioning structures during wireless charging. A ring-shaped magnet component generally consists of multiple fan-shaped magnets and iron rings. To maximize the magnetic attraction of the magnets, a Heilbeck array is usually formed by arranging and distributing the magnetic poles.

[0003] In the prior art, there are many structures that assemble fan-shaped magnet components into ring-shaped magnet components. For example, a jig for assembling multiple magnet rings is disclosed in application number 202321215345.X, which discloses a lower positioning component and an upper positioning component for forming a ring magnet from multiple fan-shaped magnets. However, when the fan-shaped magnet component is composed of multiple magnets and forms a Heilbeck array structure, the multiple magnets generate interaction forces, and there is no related jig or tooling that can achieve rapid assembly. Utility Model Content

[0004] The purpose of this utility model is to provide an assembly fixture for irregularly shaped three-piece Heilbeck magnet components. The conforming plate can position the magnets using its first conforming surface and first abutting surface. The push plate can achieve precise movement and abutting of multiple magnets using its second conforming surface and second abutting surface. The pressure plate can prevent misalignment or displacement caused by adjacent magnet abutting, ensuring smooth and precise molding of the magnet components.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an assembly fixture for irregularly shaped three-piece Heilbeck magnet components, comprising:

[0006] The base has a low platform on one side of its upper surface and a protrusion on the other side. The protrusion has a positioning groove that communicates with the low platform.

[0007] A contouring plate includes a horizontal plate and a vertical plate disposed on the horizontal plate. The horizontal plate is at least partially embedded in the positioning groove, and the vertical plate abuts against the lower platform and / or the positioning groove. At least one assembly area for placing multiple magnets is formed between the horizontal plate and the vertical plate. A first contouring surface is provided on the side of the horizontal plate adjacent to the assembly area, and a first abutting surface is provided on the side of the vertical plate adjacent to the assembly area.

[0008] A pressure plate, which is used to abut against the upper end of the magnet located within the assembly area.

[0009] The push plate includes a second contoured surface and a second abutting surface. When the push plate extends into the assembly area below the pressure plate, the second abutting surface slides along the first abutting surface, and the second contoured surface abuts against the adjacent magnet and pushes multiple magnets to abut against the first contoured surface to form a magnet assembly.

[0010] As a further optimization, the contour plate is made of magnetic material, and the lower end face of the base is provided with multiple mounting holes below the contour plate. The mounting holes are equipped with magnets to ensure the stability of the contour plate on the base.

[0011] As a further optimization, the height of the contour plate is greater than or equal to the height of the push plate to avoid interference between the push plate and the pressure plate.

[0012] As a further optimization, two assembly areas are symmetrically formed on the contour plate.

[0013] As a further optimization, the pressure plate is made of a magnetically conductive material; there are two pressure plates, which match the number of assembly areas.

[0014] As a further optimization, the opposite sides of the horizontal plate form a pair of inclined contact surfaces that abut against the sidewalls of the positioning groove.

[0015] As a further optimization, a positioning block is provided on the low platform on the opposite side of the positioning groove, which can abut against the contour plate.

[0016] As a further optimization, the positioning block and the vertical plate are in surface contact to ensure stable contact.

[0017] As a further optimization, the low platform has a concave surface on one side away from the vertical plate, and the concave surface extends to at least part of the assembly area below, to facilitate the removal of the magnet assembly.

[0018] As a further optimization, the concave surface extends to at least part of the underside of the transverse plate, facilitating the removal of the contour plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The contour plate can position the magnet using its first contour surface and first contact surface. The push plate can achieve precise movement and contact of multiple magnets using its second contour surface and second contact surface. The pressure plate can prevent misalignment or displacement caused by magnets contacting each other, ensuring smooth and precise molding of the magnet assembly.

[0021] 2. When the contour plate and pressure plate are made of magnetic material, the stability of the assembly fixture and the formed magnetic components can be ensured by cooperating with the magnets adsorbed on the base, making them easy to move. Attached Figure Description

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figs. 1 to 3 As shown, an assembly fixture for a non-standard three-piece Helbeck magnet assembly includes a base 10, a contour plate 20, a pressure plate 30, and a push plate 40. A low platform 101 is formed on one side of the upper surface of the base 10, and a protrusion 102 is formed on the other side. The protrusion 102 has a positioning groove 100 communicating with the low platform 101. The contour plate 20 includes a horizontal plate 21 and a vertical plate 22 disposed on the horizontal plate 21. The horizontal plate 21 is at least partially embedded in the positioning groove 100, and the vertical plate 22 abuts against the low platform 101 and / or within the positioning groove 100. At least one spacer for placing multiple magnets is formed between the horizontal plate 21 and the vertical plate 22. In the assembly area 200, a first contoured surface 201 is provided on the side of the horizontal plate 21 adjacent to the assembly area 200, and a first abutting surface 202 is provided on the side of the vertical plate 22 adjacent to the assembly area 200. The pressure plate 30 is used to abut against the upper end of the magnet located in the assembly area. The push plate 40 includes a second contoured surface 401 and a second abutting surface 402. When the push plate 40 extends into the assembly area 200 below the pressure plate 30, the second abutting surface 402 slides along the first abutting surface 202, and the second contoured surface 401 abuts against the adjacent magnet and pushes multiple magnets to abut against the first contoured surface 201 to form a magnet assembly.

[0030] Combination Fig. 6As shown, the magnet assembly 50 includes a first magnet 501, a second magnet 502, and a third magnet 503. The lengths of the three magnets increase sequentially, and the heights of the three magnets are the same, all being higher than the height of the contour plate 20. The first magnet 501 and the third magnet 503 are respectively bonded to the front and rear sidewalls of the second magnet 502 to form a fan-shaped magnet assembly 50. The second magnet 502 is magnetized in a front-to-back mirror image, while the first magnet 501 and the third magnet 503 are magnetized in a top-to-bottom mirror image, and the magnetic poles of the two magnets are opposite at the top, thus forming a three-piece Heilbeck magnet assembly. When forming the magnet assembly 50 using the assembly fixture of this utility model, the third magnet 503 is placed in the assembly area 200, with one side abutting against the first contour surface 201 and the other side abutting against the first contact surface 202. The second magnet 502 is placed in the assembly area 200, with one side abutting against the first contact surface 202 and forming a gap with the third magnet 503. The first magnet 501 is placed in the assembly area 200, with one side abutting against the first contact surface 202 and located on the side away from the third magnet 503, forming a gap with the second magnet 502. An adhesive layer (such as glue) is applied to the positions where the three magnets need to be connected. The lower end of the pressure plate 30 is then... The insert plate 40 is inserted into the assembly area 200 by applying a certain downward pressure to the upper surfaces of the first magnet 501, the second magnet 502, and the third magnet 503. This causes the second contact surface 402 to contact the first contact surface 202, and the second contour surface 401 to contact the first magnet 501. This pushes the insert plate 40 to move, and the second contact surface 402 slides along the first contact surface 202. During the movement of the insert plate 40, the first magnet 501 contacts the second magnet 502, and the second magnet 502 contacts the third magnet 503. This achieves the contact and bonding of the three magnets to form a fan-shaped magnet assembly 50. In the assembly process described above, the contour plate 20, with its first contour surface 201 and first contact surface 202, provides initial positioning for the magnets, ensuring accurate orientation of each magnet. The push plate 40, with its second contour surface 402 fully contacting the first magnet 501 and its second contact surface 402 engaging with the first contact surface 202, enables precise movement and contact of multiple magnets. The pressure plate 30 ensures the interaction force when magnets are in close contact, preventing misalignment or displacement. Furthermore, the assembled magnet assembly 50, with its position unchanged, is baked on a heating platform (such as an oven) to rapidly cure the adhesive layer. In this process, the base 10 and the contour plate 20 can be placed together on the heating platform as a carrier.

[0031] like Fig. 4As shown, the contour plate 20 is confined within the positioning groove 100. To further ensure the stability of the contour plate 20 on the base, the contour plate 20 is preferably made of a magnetic material. The lower end face of the base 10 is provided with multiple mounting holes 103 below the contour plate 20. The mounting holes 103 are provided with magnetic magnets 12. The contour plate 20 can be stably fixed on the base 10 by the magnetic magnets 12.

[0032] Preferably, the height of the contour plate 20 is greater than the height of the push plate 40, which can prevent the push plate 40 from being too high and coming into contact with the pressure plate 30 supported by the magnet, thus avoiding interference with the pressure plate 30 or increasing the resistance when the push plate 40 is pushed.

[0033] Two symmetrical assembly areas 200 are formed on the contour plate 20, forming a T-shaped structure that can simultaneously hold two sets of three magnets. The two magnet assemblies 50 are formed by pushing them within one assembly area 200 using a pusher plate 40, and by flipping them and pushing them into the other assembly area 200. The presence of two assembly areas 200 improves the utilization rate of the assembly fixture. For example, during baking, the two magnet assemblies 50 can be supported by a base 10 and the contour plate 20, reducing the area occupied during baking.

[0034] Furthermore, the pressure plate 30 is made of magnetically conductive material, and the number of pressure plates 30 matches the number of assembly areas 200, with two in total. The magnetically conductive pressure plate 30 can apply downward pressure to the adsorption magnet 12 during magnet assembly, ensuring stability during assembly. Additionally, when the magnet assembly 50 is baked after its formation, the adsorption between the pressure plate 30 and the adsorption magnet 12 during the movement of the assembly fixture will securely position the magnet assembly 50 on the base 10, preventing it from falling off.

[0035] In one embodiment, the opposite sides of the horizontal plate 21 form a pair of inclined abutment surfaces 204 that abut against the sidewall of the positioning groove 100. The inclined abutment surfaces 204 can cause the horizontal plate 21 to interfere with the positioning groove 100, preventing the horizontal plate 21 from sliding out of the positioning groove 100.

[0036] Furthermore, a positioning block 11 is provided on the lower platform 101 on the opposite side of the positioning groove 100, which can abut against the contour plate 20 (such as the end of the vertical plate 22 away from the horizontal plate 21), which can also prevent the contour plate 20 from sliding out of the positioning groove 100. Preferably, the positioning block 11 and the vertical plate 22 are in surface contact.

[0037] like Fig. 5As shown, in another embodiment of this utility model, a concave surface 1010 is provided on the side of the low platform 101 away from the vertical plate 22. The concave surface 1010 is a horizontal structure and extends to at least part of the assembly area 200 below. For example, after the magnet assembly 50 is baked on the assembly fixture, when it is necessary to remove the magnet assembly 50, the pressure plate 30 is first removed (to overcome the attraction between the pressure plate 30 and the adsorption magnet 12), and the insert plate 40 is moved in the concave surface 1010 so that it is partially located below the assembly area 200 and below the assembly magnet 50, such as the contact area 1011 located below the left side of the assembly magnet 50. By lifting one end of the insert plate 40, the insert plate 40 in the contact area 1011 is moved upward, so that the assembly magnet 50 overcomes the attraction with the adsorption magnet 12, and thus the assembly magnet 50 is removed more easily.

[0038] Furthermore, the concave surface 1010 extends to at least part of the horizontal plate 21 below. Similarly, when it is necessary to remove the contour plate 20 for cleaning or replacement, the contour plate 20 can also be removed by moving part of the insert plate 40 into the contact area 1011 located below the horizontal plate 21.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
