Description

Technical Field

[0001] The present invention belongs to the technical field of magnetic science, and specifically relates to a strong magnetic assembly and a manufacturing method thereof. Background Art

[0002] In the existing technologies that use the method of assembling magnets to increase the influence distance of magnetic lines and the surface magnetic strength, glue bonding is used for positioning and fixing. Since the magnets themselves mostly use powerful magnets such as neodymium iron boron for combination, the repulsive force between them is very strong. During the assembly process, the distance between them is not easy to control, and it is easy to cause damage to the magnets. Fixing by drilling holes in the magnet and the fixing plate to install screws will greatly weaken the overall performance. Fixing through fixing holes (square holes, round holes, etc.) also requires bonding first and then fixing. It is time-consuming and laborious, and it is not easy to repair the damage caused by vibration, dropping, etc. during use.

[0003] Since the magnets themselves mostly use powerful magnets such as neodymium iron boron for combination, the repulsive force between them is very strong. During the assembly process, the distance between them is not easy to control, and it is easy to cause damage to the magnets. The existing methods for installing and fixing magnet combinations include glue bonding, screw fixing, embedding grooves, etc. Glue fixing is not environmentally friendly and is prone to displacement and falling off after aging; screw fixing will weaken the overall magnetic performance and will damage the magnet coating during the assembly process, resulting in magnet rusting and reducing performance; embedding groove fixing requires high mold opening costs and cannot be adjusted once formed, with too many limitations.

[0004] Based on the above problems, we propose a strong magnetic assembly and a manufacturing method thereof. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a strong magnetic assembly and a manufacturing method thereof to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A strong magnetic assembly includes a fixed sleeve body, a powerful magnet, and a cover plate. The powerful magnet is arranged inside the fixed sleeve body, and cover plates are arranged on both sides of the fixed sleeve body on one side of the powerful magnet;

[0007] The shape of the vertical cross-section of the fixed sleeve body includes but is not limited to triangle, circle, square, trapezoid, polygon. The shape of the vertical cross-section of the powerful magnet includes but is not limited to triangle, circle, square, trapezoid, polygon. Multiple powerful magnets are stacked up and down in the way of like-pole stacking or unlike-pole stacking. The fixed sleeve body is made of non-magnetic materials including but is not limited to aluminum, plastic, nylon. The fixed sleeve body is designed with a multi-layer structure, which can be one layer, two layers or multiple layers.

[0008] To further optimize this technical solution, a placement groove / hole is provided inside the fixed sleeve body. Wedge-shaped grooves are provided on both sides of the placement groove / hole. A fixed baffle is provided at the top position of the wedge-shaped groove. The outermost powerful magnet is fixed by inserting a wedge block into the wedge-shaped groove. A fixed screw groove / hole is provided on the surface of one end of the fixed sleeve body around the outside of the placement groove / hole. The surface of the cover plate is fixedly assembled with the fixed sleeve body by being threadedly connected to the fixed screw groove / hole with a fixed screw.

[0009] To further optimize this technical solution, the strong magnetic assembly further includes a powerful magnet. The powerful magnet is placed in contact with the upper surface of the substrate. A magnetic isolation block is provided in the interval between the powerful magnets on the upper surface of the substrate. The substrate is inserted into the inside of the fixed sleeve body through the placement groove / hole. The upper surface of the substrate is in contact with the lower surface of the fixed baffle to fix the substrate. After the substrate is inserted into the inside of the fixed sleeve body.

[0010] To further optimize this technical solution, the powerful magnet is made of neodymium iron boron material. The substrate is made of a magnetic conductive or non-magnetic conductive material. The wedge block inserted into the wedge-shaped groove is made of a non-magnetic conductive material. The magnetic isolation block is made of a non-magnetic conductive and magnetic absorbing material including wood, plastic, acrylic, rubber, aluminum, copper, etc.

[0011] A manufacturing method of a strong magnetic assembly is based on the above-mentioned strong magnetic assembly for manufacturing, and includes the following specific steps:

[0012] S1. Place the substrate at one end of the fixed sleeve body, and use a cover plate to fix the other end of the fixed sleeve body to make it in a closed state;

[0013] S2. Place the first powerful magnet in contact with the upper surface of the substrate and slide it to the designated design position;

[0014] S3. Place the substrate with the first powerful magnet into the placement groove / hole;

[0015] S4. Place the magnetic isolation block on the upper surface of the substrate inside the fixed sleeve body and slide it into contact with one side of the first powerful magnet;

[0016] S5. Place the second powerful magnet in contact with the upper surface of the substrate and slide it into contact with one side of the magnetic isolation block;

[0017] S6. Place the powerful magnets and magnetic isolation blocks in sequence according to the design. After the last powerful magnet is placed, directly push all the powerful magnets and magnetic isolation blocks into place at one time by an external force, then fix them by inserting a wedge block into the wedge-shaped groove, and finally fix the cover plate by means of screwing.

[0018] Further optimize this technical solution, the substrate can be processed into a special shape to define the position of the magnet by the shape.

[0019] Further optimize this technical solution, the magnetic isolation block can be processed into a special shape and sleeved on the powerful magnet, which can prevent the magnet from shifting, can also define the distance between magnets, and protect the magnetic field line distance.

[0020] Further optimize this technical solution, when the powerful magnet is pushed into the fixed sleeve body, it can be directly pushed into the inner part of the placement groove / hole without adding a magnetic isolation block in sequence, or a magnetic isolation block can be added and pushed into the inner part of the placement groove / hole in different intervals.

[0021] Further optimize this technical solution, the manufacturing method can also not use the substrate, and directly insert the powerful magnet into the inner part of the placement groove / hole.

[0022] Compared with the prior art, the present invention provides a strong magnetic assembly and its manufacturing method, which have the following beneficial effects:

[0023] 1. For this strong magnetic assembly and its manufacturing method, by utilizing the property that the powerful magnet adsorbs iron parts, the same - pole sides of the magnets are placed in contact on a magnetic conductive material such as a steel plate. Due to the large adsorption contact area, it will not fall off by itself, and the connection of the same poles can push up the influence distance of the magnetic field lines on the other side (the other pole), preventing the problem that the magnets bonded with glue in the prior art fall off and shift due to vibration and dropping, resulting in performance degradation or harm to the human body. When the magnets are placed with the same poles, the magnetic field lines can be pushed up, and when placed with different polarities, the density of the magnetic field lines can be enhanced. By different combination methods of the powerful magnets, the effect of pushing up the magnetic field lines is achieved, making the magnetic field line induction distance of this assembly farther.

[0024] 2. For this strong magnetic assembly and its manufacturing method, by reducing the usage amount of the powerful magnet, not only the cost is saved, but also a better effect is achieved. At the same time, the assembly is convenient, there is no gluing process, preventing chemical pollution, and the possibility of harm to the human body during the assembly process can be prevented.
