Description

Technical Field

[0001] This invention relates to a suspension device, and more particularly to a magnetic component, its manufacturing method, and a suspension device having the magnetic component. Background Technology

[0002] An existing suspension device, such as a suspension device used on a motor suspension, typically uses a spring or a pneumatic cylinder as the return component.

[0003] However, after prolonged use, the springs in the suspension device will gradually lose elasticity due to deformation, resulting in a decrease in return speed or reciprocating speed, which is detrimental to stable use in precision mechanisms. Meanwhile, the pneumatic cylinder will experience gas loss, leading to a drop in air pressure and directly causing the return function to fail. Summary of the Invention

[0004] The first objective of this invention is to provide a magnetic component that can improve upon at least one of the aforementioned drawbacks.

[0005] The magnetic component of the present invention can generate a magnetic field and can be movably mounted on a magnetically conductive component extending along an axis. The magnetically conductive component includes a first magnetically conductive end and a second magnetically conductive end arranged in opposite directions along an axis parallel to the axis. The magnetic component includes a main body, a first connecting end, a second connecting end, a plurality of magnets, and an adhesive layer.

[0006] The main body extends along the axis and is movably mounted on the magnetic conductor. A first connecting end is disposed at one end of the main body along the axis. A second connecting end is disposed at the other end of the main body opposite to the first connecting end, along the axis. A plurality of magnets are fixedly arranged side-by-side within the main body along the axis, with the N pole and S pole of each magnet located on opposite sides of the axis, and the N pole of each magnet connected to the N pole of an adjacent magnet, and the S pole of each magnet connected to the S pole of an adjacent magnet. An adhesive layer is bonded between the magnets and the main body. When the magnetic component is in an extended position relative to the magnetic conductor, the magnet generates a magnetic attraction force on the magnetic conductor, causing the first magnetically conductive end of the magnetic conductor to move and reset along the axis toward the first connecting end.

[0007] The magnetic component of the present invention has a hollow cylindrical body with an inner peripheral surface that defines an accommodating space around the axis. The magnet is disposed in the accommodating space and connected to the inner peripheral surface of the body through the adhesive layer. The magnetic conductive component defines a cavity around the axis for the magnetic component to pass through.

[0008] The magnetic component of the present invention comprises an inner bushing that surrounds the axis and allows the magnetic conductor to move through it, and an outer bushing that surrounds the inner bushing. The first connecting end and the second connecting end are located on opposite sides of the outer bushing along the axial direction. Each magnet surrounds the inner bushing and is connected between the inner bushing and the outer bushing through the adhesive layer.

[0009] A second objective of the present invention is to provide a method for manufacturing the magnetic component.

[0010] The method for manufacturing the magnetic component of the present invention includes the following steps:

[0011] (A) Prepare a main body extending along the axis and a plurality of unsaturated magnets;

[0012] (B) Detect and mark the N and S poles of each of the magnets;

[0013] (C) The magnets are sequentially connected and fixed to the body along an axial direction parallel to the axis using adhesive, such that the N pole and S pole of each magnet are located on opposite sides of the axis, and the N pole of each magnet is connected to the N pole of the adjacent magnet, and the S pole of each magnet is connected to the S pole of the adjacent magnet; and

[0014] (D) The magnet is saturated with magnets so that the magnetized magnet and the main body form the magnetic element.

[0015] In the method for manufacturing the magnetic component of the present invention, in step (A), the main body is hollow cylindrical and has an inner peripheral surface that defines an accommodating space around the axis; in step (C), the magnet is disposed in the accommodating space and connected to the inner peripheral surface of the main body by the adhesive.

[0016] In the method for manufacturing the magnetic component of the present invention, in step (A), the main body includes an inner bushing surrounding the axis and an outer bushing surrounding the inner bushing; in step (C), each magnet surrounds the inner bushing and is connected between the inner bushing and the outer bushing by the adhesive.

[0017] A third objective of the present invention is to provide a suspension device having the magnetic element.

[0018] The suspension device with magnetic components according to the present invention includes a magnetic conductive component and a magnetic component.

[0019] The magnetic conductive element extends along an axis and includes a first magnetically conductive end and a second magnetically conductive end disposed opposite to each other along an axial direction parallel to the axis. The magnetic element includes a first connecting end and a second connecting end disposed opposite to each other along the axial direction. The magnetic element is capable of generating a magnetic field and is movably mounted on the magnetic conductive element along the axial direction. The N pole and S pole of the magnetic element extend along the axial direction and are respectively located on two opposite sides of the axial direction. When the magnetic element is in an extended position relative to the magnetic conductive element, the magnetic element generates a magnetic attraction force that causes the first magnetically conductive end of the magnetic conductive element to move and reset towards the first connecting end along the axial direction.

[0020] The suspension device with magnetic components of the present invention includes a magnetic conductive component defining a cavity around an axis. The magnetic component further includes a main body extending along the axis in a hollow cylindrical shape and movable along the axis and installed in the cavity; a plurality of magnets fixedly disposed in the main body in parallel along the axis; and an adhesive layer bonded between the magnets and the main body. The first connecting end and the second connecting end are located on opposite sides of the main body along the axis. The N pole and S pole of each magnet are located on opposite sides of the axis, and the N pole of each magnet is connected to the N pole of an adjacent magnet, and the S pole of each magnet is connected to the S pole of an adjacent magnet.

[0021] The suspension device with magnetic components of the present invention further includes a main body, an adhesive layer, and a plurality of magnets. The main body has an inner bushing that surrounds the axis and allows the magnetic conductive component to move through it, and an outer bushing that surrounds the inner bushing. The first connecting end and the second connecting end are located on opposite sides of the outer bushing along the axial direction. The magnets are connected in parallel along the axial direction around the inner bushing and are fixed between the inner bushing and the outer bushing by the adhesive layer. The N pole and S pole of each magnet are located on opposite sides of the axis, and the N pole of each magnet is connected to the N pole of the adjacent magnet, and the S pole of each magnet is connected to the S pole of the adjacent magnet.

[0022] The suspension device with magnetic components described in this invention further includes a sliding bearing disposed between the main body and the magnetic conductive component.

[0023] The beneficial effect of the present invention is that when the magnetic conductive element is in the extended position relative to the magnetic element, the magnetic element generates a magnetic attraction force that magnetically attracts the magnetic conductive element, causing the first magnetically conductive end of the magnetic conductive element to move and reset along the axial direction toward the first connecting end.

[0030] Figure 7 yes Figure 6 An incomplete magnified view of a part. Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Before the present invention is described in detail, it should be noted that the relative position terms used in the following description, such as "front", "back", "left", "right", "up", and "down", are based on the orientation shown in each figure and the normal use orientation, and similar elements are represented by the same number.

[0032] See Figures 1 to 3 A first embodiment of the suspension device 100 with magnetic components of the present invention is suitable for installation on a linear module 7, the linear module 7 having a body 71 and a slide 72 movably disposed on the body 71.

[0033] The suspension device 100 with magnetic components includes a magnetic conductor 1, a magnetic component 2, and a sliding bearing 3.

[0034] The magnetic conductor 1 extends along an axis L and defines a chamber 11 around the axis L. The magnetic conductor 1 includes a first magnetic end 12 connected to the slide 72 by a plate and a screw (not shown), and a second magnetic end 13 along an axial direction X parallel to the axis L, opposite to the first magnetic end 12.

[0035] The magnetic component 2 is movably mounted in the cavity 11 of the magnetic conductive component 1 along the axial direction X. The magnetic component 2 includes a main body 21 extending along the axis L and movably mounted in the cavity 11 of the magnetic conductive component 1 along the axial direction X; a first connecting end 22 disposed at one end of the main body 21 along the axial direction X and connected to the slide 72 by a plate and screws; a second connecting end 23 disposed at the other end of the main body 21 opposite to the first connecting end 22 and passing through the cavity 11 along the axial direction X; a plurality of magnets 24 fixedly fixed in the main body 21 in parallel along the axial direction X; and an adhesive layer 25 bonded between the magnets 24 and the main body 21.

[0036] The main body 21 is hollow cylindrical and has an inner circumferential surface 211 that defines an accommodating space 212 around the axis L.

[0037] The magnet 24 is disposed in the accommodating space 212 and connected to the inner peripheral surface 211 of the main body 21 through the adhesive layer 25. The N pole 241 and S pole 242 of each magnet 24 are located on opposite sides of the axis L, and the N pole 241 of each magnet 24 is connected to the N pole 241 of the adjacent magnet 24, and the S pole 242 of each magnet 24 is connected to the S pole 242 of the adjacent magnet 24.

[0038] In this embodiment, the magnetic conductive component 1 is a magnetically conductive material that can be attracted by the magnet 24, such as iron, steel, nickel, etc., and the adhesive layer 25 is formed by applying an adhesive to the inner peripheral surface 211 of the magnet 24 and the main body 21 and then curing it.

[0039] Therefore, the magnetic element 2 can generate a magnetic field and move relative to the magnetic conductor 1 along the axial direction X, and the N pole 241 and S pole 242 of the magnetic element 2 are arranged side by side along the axial direction X and are located on opposite sides of the axis L. In other variations of this embodiment, the magnetic element 2 may also include only a single elongated magnet (not shown) extending along the axial direction X, and the N pole and S pole of the magnet extend along the axial direction X and are located on opposite sides of the axis L, but this is not intended to be a limitation.

[0040] The sliding bearing 3 extends along the axial direction X and is fixed in the cavity 11 of the magnetic conductor 1 and surrounds the body 21 of the magnetic component 2, so that the magnetic component 2 can slide smoothly relative to the magnetic conductor 1 along the axial direction X.

[0041] The process of the linear module 7 reciprocating through the suspension device 100 with magnetic components described in this embodiment is explained below.

[0042] See Figure 1 , Figure 2 , Figures 4 to 5 In this embodiment, the body 71 of the linear module 7 can be mounted on a frame (not shown) and electrically connected to a motor (not shown) for driving the slide 72 to move up and down.

[0043] When the motor drives the slide 72 to move downward, and the magnetic conductor 1 is in an extended position relative to the magnetic component 2 (see...), Figure 2 When the motor removes the external force applied to the magnetic conductor 1, the magnet 24 of the magnetic component 2 generates a magnetic attraction force to the magnetic conductor 1, causing the first magnetic end 12 of the magnetic conductor 1 to move along the axial direction X toward the first connecting end 22, thereby moving the magnetic conductor 1 relative to the magnetic component 2 back to a positioning position (see...). Figure 5 The slide 72 and the body 71 are folded together side by side.

[0044] Compared to existing suspension devices that utilize springs or pneumatic cylinders, which generate different reset forces at different strokes, leading to unstable reset, in this embodiment, the magnetic guide 1 is attracted by the same magnitude of magnetic force when it moves along the axial direction X to different stroke positions relative to the positioning position. This allows the slide 72 to be reset more stably by the suspension device 100 with magnetic components in this embodiment, further improving the accuracy of the slide 72's movement and positioning.

[0045] Therefore, in the first embodiment of the suspension device 100 with magnetic components of the present invention, when the magnetic conductive component 1 is in the extended position relative to the magnetic component 2, the magnet 24 generates a magnetic attraction force that magnetically attracts the magnetic conductive component 1, causing the first magnetically conductive end 12 of the magnetic conductive component 1 to move and reset along the axial direction X toward the first connecting end 22. This enables the magnetic conductive component 1 to stably overcome the downward gravity and accurately reset, thus effectively achieving the purpose of the present invention.

[0046] See Figure 2 , Figure 3 In this embodiment, the method for manufacturing the magnetic component 2 of the present invention includes the following steps S1 to S4:

[0047] Step S1: Prepare a hollow cylindrical body 21 extending along an axis L, and a plurality of unsaturated magnetized magnets 24. The body 21 has an inner peripheral surface 211 that defines an accommodating space 212 around the axis L.

[0048] Step S2: Detect and mark the N pole 241 and S pole 242 of each magnet 24.

[0049] Step S3: The magnets 24 are sequentially connected to each other along an axial direction X parallel to the axis L using an adhesive (not shown) and disposed in the accommodating space 212. The magnets are also connected to the inner peripheral surface 211 of the main body 21 using the adhesive, such that the N pole 241 and S pole 242 of each magnet 24 are located on opposite sides of the axis L, and the N pole 241 of each magnet 24 is connected to the N pole 241 of the adjacent magnet 24, and the S pole 242 of each magnet 24 is connected to the S pole 242 of the adjacent magnet 24. After the adhesive is cured, it forms the adhesive layer 25.

[0050] Step S4: Saturate magnetize the magnet 24 so that the magnetized magnet 24 and the main body 21 form the magnetic element 2.

[0051] Since the magnetic field strength of the unsaturated magnet 24 in step S1 is less than that of the saturated magnet 24 in step S4, the difficulty of connecting the magnet 24 in parallel with the magnetic poles can be reduced in step S3, thereby improving the ease of manufacturing.

[0052] Therefore, the magnetic component 2 manufactured by the method of the present invention can be manufactured and sold separately, and can be applied to the magnetic conductor 1 of the suspension device 100 having the magnetic component, and can stably overcome the downward gravity and accurately reset the magnetic conductor 1, thus reliably achieving the purpose of the present invention.

[0053] See Figure 1 , Figure 2 , Figure 6 , Figure 7 A second embodiment of the suspension device 200 with magnetic components of the present invention includes a magnetic conductor 4, a magnetic component 5, and a sliding bearing 6. The magnetic conductor 4 of the second embodiment is similar in appearance to the magnetic component 2 of the first embodiment, and the magnetic component 5 of the second embodiment is similar in appearance to the magnetic conductor 1 of the first embodiment, the difference being:

[0054] In this embodiment, the magnetic conductive element 4 extends along the axis L and includes a first magnetic conductive end 41 and a second magnetic conductive end 42 disposed opposite to each other along the axis X. The first magnetic conductive end 41 is connected to the body 71 of the linear module 7 via a plate and screws.

[0055] The magnetic component 5 includes a main body 51, a first connecting end 52, a second connecting end 53, a plurality of magnets 54, and an adhesive layer 55.

[0056] The main body 51 has an inner bushing 511 that surrounds the axis L and through which the magnetic conductor 4 can move, and an outer bushing 512 that surrounds the inner bushing 511. The first connecting end 52 and the second connecting end 53 are located on opposite sides of the outer bushing 512 along the axial direction X, and the first connecting end 52 is connected to the slide 72 by a plate and a screw (not shown).

[0057] The magnets 54 are arranged side by side along the axial direction X around the inner bushing 511 and are bonded to the inner bushing 511 and the outer bushing 512 by the adhesive layer 55.

[0058] The N pole 541 and S pole 542 of each magnet 54 are located on opposite sides of the axis L, and the N pole 541 of each magnet 54 is connected to the N pole 541 of the adjacent magnet 54, and the S pole 542 of each magnet 54 is connected to the S pole 542 of the adjacent magnet 54.

[0059] The sliding bearing 6 is located inside the inner bushing 511 and allows the magnetic conductive element 4 to pass through, so that the magnetic conductive element 4 can move smoothly relative to the magnetic element 5 along the axial direction X.

[0060] Therefore, in the second embodiment of the suspension device 200 with magnetic components of the present invention, when the magnetic conductive component 4 is in the extended position relative to the magnetic component 5, the magnet 54 generates a magnetic attraction force that magnetically attracts the magnetic conductive component 4, causing the first connecting end 52 of the magnetic component 5 to move and reset along the axial direction X toward the first magnetically conductive end 41 of the magnetic conductive component 4. This enables the magnetic component 5 to stably overcome the downward gravity and accurately reset, thus effectively achieving the purpose of the present invention.

[0061] In this embodiment, the method for manufacturing the magnetic component 5 of the present invention includes the following steps S1' to S4':

[0062] Step S1': Prepare a body 51 and a plurality of unsaturated magnets 54. The body 51 includes an inner bushing 511 surrounding the axis L and an outer bushing 512 surrounding the inner bushing 511.

[0063] Step S2': Detect and mark the N pole 541 and S pole 542 of each magnet 54.

[0064] Step S3': The magnets 54 are sequentially connected to each other along the axial direction X using an adhesive. Each magnet 54 surrounds the inner bushing 511 and is connected between the inner bushing 511 and the outer bushing 512 through the adhesive, so that the N pole 541 and S pole 542 of each magnet 54 are located on opposite sides of the axial direction L, and the N pole 541 of each magnet 54 is connected to the N pole 541 of the adjacent magnet 54, and the S pole 542 of each magnet 54 is connected to the S pole 542 of the adjacent magnet 54. After the adhesive cures, the adhesive layer 55 is formed.

[0065] Step S4': Saturate magnetize the magnet 54 so that the magnetized magnet 54 and the main body 51 form the magnetic element 5.

[0066] Therefore, the magnetic component 5 manufactured by the method of the present invention can be applied to the magnetic conductive component 4 of the suspension device 200 having the magnetic component, so that the magnetic component 5 can stably overcome the downward gravity and accurately reset, thus achieving the purpose of the present invention.

[0067] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
