Referring to fig. 1 to 3, a first embodiment of a suspension device 100 with magnetic elements according to the present invention is adapted to be mounted on a linear module 7, the linear module 7 having a body 71 and a slider 72 movably disposed on the body 71.
The suspension device 100 with magnetic elements comprises a magnetic element 1, a magnetic element 2, and a sliding bearing 3.
The magnetically permeable member 1 extends along an axis L and defines a chamber 11 about the axis L. And the magnetically conductive member 1 comprises a first magnetically conductive end portion 12 connected to the slider 72 by a plate member and a screw (not shown), and a second magnetically conductive end portion 13 opposite to the first magnetically conductive end portion 12 along an axial direction X parallel to the axis L.
The magnetic member 2 is movably mounted in the chamber 11 of the magnetic conductive member 1 in the axial direction X. The magnetic member 2 includes a main body 21 extending along the axis L and movably mounted in the cavity 11 of the magnetic conductive member 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 a screw, a second connecting end 23 disposed at the other end of the main body 21 opposite to the first connecting end 22 and penetrating the cavity 11 along the axial direction X, a plurality of magnets 24 fixedly disposed in the main body 21 in parallel connection along the axial direction X, and an adhesive layer 25 adhered between the magnets 24 and the main body 21.
The main body 21 has a hollow cylindrical shape and has an inner peripheral surface 211 defining an accommodating space 212 around the axis L.
The magnet 24 is disposed in the accommodation space 212 and is connected to the inner peripheral surface 211 of the main body 21 via the adhesive layer 25. The N pole 241 and the S pole 242 of each magnet 24 are respectively located at two opposite sides of the axis L, and the N pole 241 of each magnet 24 is connected to the N pole 241 of an adjacent magnet 24, and the S pole 242 of each magnet 24 is connected to the S pole 242 of an adjacent magnet 24.
In this embodiment, the magnetic conductive member 1 is made of a magnetic 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 magnet 24 and the inner peripheral surface 211 of the main body 21 and then curing.
Therefore, the magnetic member 2 can generate a magnetic field and can move relative to the magnetic conductive member 1 along the axial direction X, and the N pole 241 and the S pole 242 of the magnetic member 2 are juxtaposed along the axial direction X and are respectively located on opposite sides of the axis L. In other variations of the present embodiment, the magnetic member 2 may include only one magnet (not shown) extending along the axial direction X, and the N pole and the S pole of the magnet extend along the axial direction X and are located at opposite sides of the axis L, which is not limited thereto.
The sliding bearing 3 extends along the axial direction X and is fixedly arranged in the cavity 11 of the magnetic conductive member 1 and surrounds the main body 21 of the magnetic member 2, so that the magnetic member 2 can smoothly slide along the axial direction X relative to the magnetic conductive member 1.
The following description will be made of the process of reciprocating the linear module 7 by the suspension device 100 with a magnetic member of the present embodiment.
Referring to fig. 1, 2 and 4 to 5, in the present embodiment, the body 71 of the linear module 7 may be mounted on a frame (not shown) and electrically connected to a motor (not shown) for driving the slider 72 to move up and down.
When the motor drives the slider 72 to move downward and the magnetic conductive member 1 is located at an extended position (see fig. 2) relative to the magnetic member 2 and the motor removes the external force applied to the magnetic conductive member 1, the magnet 24 of the magnetic member 2 generates a magnetic attraction force to magnetically attract the magnetic conductive member 1 so that the first magnetic conductive end 12 of the magnetic conductive member 1 moves toward the first connecting end 22 along the axial direction X, and the magnetic conductive member 1 moves and resets to a positioning position (see fig. 5) relative to the magnetic member 2, and the slider 72 is folded in parallel with the body 71.
Compared with the existing suspension device using a spring or a pneumatic cylinder, which generates different restoring force during different strokes, the present embodiment has the disadvantage of unstable restoring, in which the magnetic conductive member 1 is attracted by the magnetic force of the same magnitude when moving to different strokes along the axial direction X compared with the positioning position, so that the sliding seat 72 can be restored more stably by the suspension device 100 with a magnetic member of the present embodiment, and the accuracy of moving and positioning of the sliding seat 72 is further improved.
Therefore, in the first embodiment of the suspension device 100 with a magnetic member according to the present invention, when the magnetic conductive member 1 is located at the extended position relative to the magnetic member 2, the magnet 24 generates a magnetic attraction force that magnetically attracts the magnetic conductive member 1 to move the first magnetic conductive end 12 of the magnetic conductive member 1 toward the first connecting end 22 along the axial direction X, so that the magnetic conductive member 1 can stably overcome the downward gravity and accurately reset, and the object of the present invention can be achieved.
Referring to fig. 2 and 3, in the present embodiment, the method for manufacturing the magnetic element 2 according to the present invention includes the following steps S1 to S4:
step S1: a hollow cylindrical body 21 extending along an axis L and a plurality of unsaturated magnetized magnets 24 are prepared, the body 21 having an inner peripheral surface 211 defining a receiving space 212 around the axis L.
Step S2: n pole 241 and S pole 242 of each magnet 24 are detected and marked.
Step S3: the magnets 24 are sequentially connected to each other along an axial direction X parallel to the axis L by an adhesive (not shown) and disposed in the accommodating space 212 and connected to the inner peripheral surface 211 of the main body 21 by the adhesive, such that the N pole 241 and the S pole 242 of each magnet 24 are located at two opposite sides of the axis L, the N pole 241 of each magnet 24 is connected to the N pole 241 of an adjacent magnet 24, the S pole 242 of each magnet 24 is connected to the S pole 242 of an adjacent magnet 24, and the adhesive is cured to form the adhesive layer 25.
Step S4: the magnet 24 is saturated and magnetized so that the magnetized magnet 24 and the main body 21 are formed into the magnetic material 2.
Since the magnetic field intensity of the magnet 24 that is not saturated and magnetized in the step S1 is smaller than the magnetic field intensity of the magnet 24 that is saturated and magnetized in the step S4, the difficulty of connecting the magnet 24 and the magnetic pole in parallel can be reduced in the step S3, so that the convenience of manufacturing is improved.
Therefore, the magnetic member 2 manufactured by the method of manufacturing a magnetic member according to the present invention can be manufactured and sold separately, and can be applied to the magnetic conductive member 1 of the suspension device 100 having a magnetic member, and the magnetic conductive member 1 can be stably and precisely reset against the downward gravity, so that the object of the present invention can be surely achieved.

The magnet 54 surrounds the inner hub 511 in parallel connection along the axial direction X and is adhered between the inner hub 511 and the outer hub 512 by the adhesive layer 55.
The N pole 541 and the S pole 542 of each magnet 54 are located on opposite sides of the axis L, respectively, and the N pole 541 of each magnet 54 is connected to the N pole 541 of an adjacent magnet 54, and the S pole 542 of each magnet 54 is connected to the S pole 542 of an adjacent magnet 54.
The sliding bearing 6 is located in the inner sleeve 511 and is used for the magnetic conductive member 4 to pass through, so that the magnetic conductive member 4 can smoothly move along the axial direction X relative to the magnetic member 5.
