Description

  The present invention relates to a method for manufacturing a magnetic health product in which a DLC film is formed on the surface of a bead member, and a magnetic health accessory manufactured by the manufacturing method.

  Recently, magnetic health accessories such as a magnetic necklace in which permanent magnets are connected in a bead-like manner have been used for the purpose of promoting health by magnetic force (see, for example, Patent Document 1).

  On the other hand, the applicant has focused on the far-infrared effect of carbon materials, and has proposed health accessories made of carbon materials (see Patent Document 2), and further developed health accessories that have a carbon film formed on the surface of a permanent magnet body. Various attempts are being made to achieve this goal.

  In recent years, various techniques for forming a carbon film similar to diamond on the surface of a substrate by a DLC (diamond-like carbon) film forming method have been proposed. It is also possible to produce a magnetic health accessory having a high hardness and excellent wear resistance by forming a carbon film on the surface of the film. In addition, it is particularly effective if this method is used when a film is formed on the surface of a three-dimensional base material such as a sphere without any defects.

JP 2005-87404 A Japanese Patent No. 3555928

  However, magnetic health accessories such as magnetic necklaces are made by connecting a plurality of permanent magnet bodies in a bead-like manner. Therefore, if a DLC film is individually formed on each permanent magnet body such as a sphere, production is possible. High-quality manufacturing cannot be performed. In addition, if a film is formed one by one, there is a risk that manufacturing variations may occur in the DLC films of the individual magnetic health products constituting the magnetic health accessory. If the DLC film forming process is performed in a state where the permanent magnet bodies are connected in a bead-like manner, even if a plurality of permanent magnet bodies can be formed simultaneously, the permanent magnet bodies come into contact with each other, causing unevenness and uniform DLC. A film cannot be formed.

  The present invention has been proposed in view of such circumstances, and its purpose is to improve the production efficiency of magnetic health products constituting magnetic health accessories, and to provide a DLC film formed on the surface of magnetic health products. It is an object of the present invention to provide a method for manufacturing a magnetic health product that does not cause manufacturing variations, and a magnetic health accessory manufactured using the method.

  In order to achieve the above object, a proposed method for manufacturing a magnetic health product according to the present invention is a method for manufacturing a magnetic health product, in which a DLC film is formed on the surface of each pearl member having a through hole. The member is made of a permanent magnet body or a magnet material that is magnetized after the DLC film is formed, and a conductive connection in which a plurality of pearl members are held by a conductive wire with a gap so as not to contact each other. A body is prepared, and the conductive connecting body is accommodated in a chamber of a plasma ion implantation apparatus as a target base material, and then a predetermined element ion is generated and injected into each of the pearl members. It is characterized by forming.

  According to the second aspect of the present invention, the conductive wire body forms a hump portion obtained by bending a part of the conductive wire body so as to maintain a gap with the adjacent bead member so that mutual contact is made when the DLC film is formed. It has a structure to prevent.

  According to a third aspect of the present invention, the conductive wire is attached to a part of the conductive wire in a hump-like shape so as to maintain a gap with the adjacent bead member, and at the time of forming the DLC film. It has a structure that prevents contact.

  In claim 4, the conductive wire body has a structure in which a conductive core member corresponding to a protrusion to be brought into contact with the through-hole of the bead member is covered with an insulating film on a portion excluding the protrusion, After penetrating the bead member, the protrusion is thermally expanded to prevent contact between the bead members and falling off from the conductive wire.

  According to the fifth aspect, hydrogen is contained in the element ions to be implanted for forming the DLC film.

  According to a sixth aspect of the present invention, fluorine is contained in the element ions implanted for forming the DLC film.

  According to a seventh aspect of the present invention, a magnetic health accessory includes a magnetic health product manufactured by the manufacturing method according to any one of the first to sixth aspects, and a connecting string that penetrates the magnetic health accessory so as to be connected in a rosary manner.

  In the magnetic health accessory according to claim 8, a carbon fired body having a crystal structure having a through hole is further added, and the magnetic health accessories are connected by the connecting string.

  According to the method for manufacturing a magnetic health product of the present invention, a conductive coupling body in which a plurality of rosicle members are held through a conductive wire is housed in a chamber of a plasma ion implantation apparatus, and the DLC is placed in the coupling body. Since it is the structure which forms a membrane | film | coat, the magnetic health goods which have no dispersion | variation in the formation of a DLC membrane | film | coat between bead members can be manufactured rapidly and efficiently. Moreover, since the several bead members are hold | maintained in the state which spaced apart so that it may not mutually contact, a uniform DLC film can be formed in the whole surface of each bead member.

  In particular, in the case where a hump portion formed by folding a part of a conductive wire body is formed so as to maintain a gap between the adjacent bead members, the connection body can be formed simply by bending the conductive wire body between the bead members. Therefore, it is possible to easily and quickly prepare the connected body by manual work or a simple jig.

  In particular, when a non-conductive material is attached to a part of a conductive wire in a hump shape so as to maintain a gap between adjacent bead members, a DLC film is formed on the hump portion of the non-conductive material. Therefore, after the DLC treatment, the conductive wire can be reused if the non-conductive material is removed by heat or chemicals.

  In particular, in the structure in which protrusions provided on the conductive wire are thermally expanded to prevent mutual contact of the bead members and dropping from the conductive wire, the conductive wire penetrates the bead member, DLC pretreatment such as locking of protrusions to the bead member by heating of the conductive wire and post-DLC treatment such as removal of the bead member by cooling of the conductive wire can be performed mechanically and rapidly.

  In the case of injecting element ions containing hydrogen for forming the DLC film, the DLC film can be made a glossy black color, and the magnetic health product can have a profound feeling.

  In the case of injecting elemental ions containing fluorine in the formation of the DLC film, the surface of the magnetic health product can be made a glossy iridescent color, giving a mysterious feeling.

  According to the magnetic health accessories of the present invention, the magnetic health goods manufactured by the method of the present invention are constructed by connecting the connecting strings in a rosary manner, so that the hardness is high, the sliding is good, and the gloss is high. Magnetic health accessories with excellent wear resistance can be formed. Furthermore, since the magnetic health accessories directly touch the skin, the far-infrared effect due to the DLC film can be expected, and since the magnet does not touch the skin directly, there is no risk of rough skin due to magnet allergy.

  In particular, in the case where a carbon fired body having a crystal structure having a through-hole is further added and connected by the same connecting string, the far-infrared effect by the carbon fired body can be enhanced.

(A)-(c) is a figure which shows the other example of the shape of a permanent magnet body.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  In the following, various forms of preparation steps for forming a DLC film on the surface of a bead member made of a permanent magnet body or the like in a plasma ion implantation apparatus are shown, all of which are in contact with each other. In order to avoid this, a wire-like conductive wire body is penetrated and held with a gap therebetween to form a connected body that becomes a target base material for plasma ion implantation. In addition, below, embodiment which uses a permanent magnet body as a bead member is described.

  Moreover, as a permanent magnet body, the thing below 2000 gauss is desirable for medical use and health promotion, and can be used conveniently. As the conductive wire, a flexible wire such as copper, aluminum or silver can be used.

  FIG. 1 is a perspective view of a jig used in the first embodiment. 2A to 2C are explanatory diagrams of procedures of a method for manufacturing a magnetic health product using the jig. FIG. 3 is a diagram illustrating another example of the first embodiment.

  The jig 20 shown in FIG. 1 has a plurality of recesses 21 formed vertically and horizontally so that spherical permanent magnet bodies 1 having through-holes 1a can be arranged in multiple rows. In each gap portion of the recesses 21 arranged in the left-right direction, a press groove 22 for forming a hump portion that runs in the vertical direction is formed.

  First, in the recess 21 of the jig 20, the permanent magnet bodies 1 are arranged in the lateral direction so that the through holes 1 a are aligned, and the conductive wire 2 is placed in the through holes 1 a of the permanent magnet bodies 1. It penetrates like a skewer (see FIG. 1, FIG. 2 (a) (b)).

  Next, a press die 23 having a plurality of protrusions 23a protruding downward in a comb-like shape is pressed down against the jig 20, and the conductive wire 2 is formed by the protrusions 23a and the press grooves 22 of the jig 20. Are partly bent to form the hump 11 (see FIGS. 2B and 2C). This hump portion 11 constitutes a spacer for maintaining a distance to prevent contact between adjacent permanent magnet bodies 1.

  In this way, the coupling body 10 having conductivity as a whole is formed.

  According to such a method, since it is the structure which hold | maintains the gap | interval with the adjacent permanent magnet body 1 by the hump part 11 formed by bending the conductive wire body 2, using the above jig | tools 20 is used. Thus, the connector 10 can be formed easily and quickly.

  Further, in the case of forming a connection body in which a small number of permanent magnet bodies 1 are connected to each other, such a hump portion 11 can be used as shown in FIG. It can also be formed by work.

  In FIG. 3, the conductive wire 2 is formed with a stopper portion by bending one end thereof, and then the permanent magnet body is sequentially penetrated from the other end to bend a portion thereof to form a hump portion. However, it is needless to say that the spacer portion is not limited to such a method.

  Thus, in the connection body 10 formed by such a method, a DLC film is formed on the entire surface of the permanent magnet body 1 by a known plasma ion implantation / film formation method.

  FIG. 4 is an explanatory view showing an example of a plasma ion implantation apparatus for forming a DLC film.

  The plasma ion implantation apparatus 30 includes a chamber 31, a gas introduction device 32 that introduces a gas into the chamber 31, a vacuum device 34 that evacuates the chamber 31, and a target that is disposed at a predetermined position in the chamber 31. A high voltage pulse generating power source 36 for applying a high voltage pulse to the conductor 35 connected to the base material (connector 10), and a plasma generating power source for generating a plasma around the target base material by applying high frequency power to the conductor 35 37, and a high voltage pulse generating power source 36, a plasma generating power source 37, and a superimposing device 38 provided between the conductors 35 in order to share the application of the high voltage pulse and the high frequency power with one conductor. ing.

  The gas introducing device 32 and the vacuum device 33 are connected to the inside of the chamber 31 through respective valves 34 and 34. The conductor 35 is connected to the superimposing device 38 via a feedthrough 39 (high voltage introducing portion).

  In order to perform ion implantation on the surface of the permanent magnet body 1 with the plasma ion implantation apparatus 30 configured as described above, the connection body 10 as a target base material is suspended in the chamber 31 while being connected to the conductor 35 with a hook or the like. The inside of the chamber 31 is evacuated by the vacuum device 33, and a hydrocarbon gas is introduced into the chamber 31 by the gas introduction device 32. As the hydrocarbon-based gas, methane gas can be preferably used, but other acetylene gas, propane gas and the like can also be used.

  The plasma generation power source 37 applies high-frequency power to the connection body 10 to generate plasma around the connection body 10, and then generates a high voltage pulse (negative high voltage pulse) from the high voltage pulse generation power source 36. To attract the ions in the plasma to the connector 10.

  When ions are attracted to the coupling body 10 in this way, carbon atoms contained in the ions are injected into the coupling body 10 from the surface to a predetermined depth, thereby forming a DLC film on the surface.

  Further, ions to be implanted may contain hydrogen, fluorine, or silver. Therefore, a gas containing these atoms may be used, or a mixed gas containing hydrogen gas and fluorine gas may be used. Argon gas may also be included.

  Since the connection body 10 arranged in the chamber 31 as a target base material is arranged at intervals so that the plurality of permanent magnet bodies 1 do not contact each other, it is uniformly formed on the entire surface of each individual permanent magnet body 1. A DLC film can be formed.

  If the coupling body 10 thus formed with the DLC film is separated into the permanent magnet bodies 1 by cutting the conductive wire 2 or the like, they can be used as magnetic health products.

  FIG. 5 is a schematic plan view of a magnetic health accessory using the manufactured magnetic health goods. As shown in this figure, for example, by passing the connecting string 6 through the through holes 1a (see FIG. 2) of the plurality of magnetic health products 5, the magnetic health accessories 7 such as a magnetic necklace and a magnetic bracelet can be formed.

  Since this magnetic health accessory 7 is composed of the magnetic health product 5 on which the DLC film is formed, in addition to various effects by the permanent magnet, low friction, high hardness, wear resistance, corrosion resistance, etc. by the DLC film It is possible to provide a magnetic health accessory 7 that is gentle to the skin, glossy, hard and has almost no surface deterioration. In addition, since the permanent magnet does not directly hit the skin, it is also suitable for people with allergies. Furthermore, the far infrared effect by carbon can also be acquired by a DLC film.

  Moreover, as a magnetic health accessory, in addition to the magnetic health goods 5, a carbon fired body having a crystal structure (not shown) may be further connected by a connecting string 6. In this case, the far infrared effect by the carbon fired body Etc. can be strengthened.

  Carbon materials emit far-infrared rays of the same wavelength as humans warmed by body temperature, and when far-infrared rays hit water molecules in the body, hydrogen and oxygen collide violently (causing molecular resonance action) to become kinetic energy and self-heating. As the deep temperature rises, the magnetic necklace containing a DLC film-formed magnetic health product or carbon fired body warms the neck by such far-infrared action and promotes blood circulation. The same effect as therapy can be expected.

  Further, when the implanted element ions include hydrogen atoms, the DLC film can be uniformly blackened, and the magnetic health product 1 can have a profound feeling. Moreover, in the thing containing a fluorine atom, a DLC film can be made iridescent, and also an antibacterial action can be expected. In addition, an antibacterial action can be exerted with silver atoms.

  Note that the DLC film may be formed by another DLC film forming method such as a plasma CVD method instead of the plasma ion implantation apparatus shown in FIG. Moreover, as a method of accommodating the connection body 10 in the chamber 31, it is not limited to suspension, but another arrangement method may be taken.

  Next, a second embodiment of the method for manufacturing a magnetic health product according to the present invention will be described.

  6 (a) and 6 (b) are explanatory diagrams illustrating the manufacturing method of the second embodiment.

  In this embodiment, the coupling body 10 is molded using a non-conductive material 12 as a spacer between adjacent permanent magnet bodies 1.

  That is, in this connection body 10, a plurality of permanent magnet bodies 1 are arranged in a row with the through holes 1 a aligned, and one conductive wire 2 is passed through each through hole 1 a, so A predetermined gap is ensured, and rubber or resin is attached to these gaps in a hump shape to form a spacer.

  When the DLC film forming process is performed on the connector 10 thus molded by the plasma ion implantation apparatus 30 shown in FIG. 4 or the like, the surface of the spacer portion is formed of the non-conductive material 12. Therefore, although the DLC film is formed on the surface of the permanent magnet body 1, there is an advantage that the DLC film is not formed on the surface of the spacer.

  After the DLC film formation process, if the non-conductive material 12 is removed by heat, chemicals, or equipment and the conductive wire 2 is extracted from the permanent magnet body 1, only the magnetic health product on which the DLC film is formed is used as a product. It can be taken out. Moreover, since the non-conductive material 12 is removed, the extracted conductive wire 2 can be reused.

  Next, a third embodiment of the method for manufacturing a magnetic health product according to the present invention will be described.

  FIGS. 7A to 7C are explanatory diagrams of procedures showing the manufacturing method of the third embodiment.

  In the coupling body 10 of this embodiment, the permanent magnet body 1 is removed from the conductive wire body 2 by friction between the protrusion 14 provided on the conductive wire body 2 and the inner wall of the through hole 1a of the permanent magnet body 1. It has a structure that prevents it.

  That is, in this embodiment, the conductive protrusions 14 are formed at predetermined intervals on the conductive core member, and the insulating film 13 is covered on the conductive core member except for the protrusions 14, thereby forming the conductive wire. The body 2 is constituted, and the conductive wire 2 is made to penetrate the permanent magnet body 1 and then heated, so that the protrusion 14 accommodated in the through hole 1a of the permanent magnet body is heated to expand, The coupling body 10 is formed so that the permanent magnet body 1 cannot move due to friction between the protrusion 14 and the inner wall of the through hole 1a.

  Thus, since it is the structure which thermally expands the protrusion 14 and the permanent magnet body 1 is latched, the shaping | molding of the connection body 10 can be performed easily and rapidly.

  When the DLC film forming process is performed on the thus-formed molded body 10 by using the plasma ion implantation apparatus 30 shown in FIG. 4 or the like, the insulating film 13 is coated on the conductive wire 2 except for the protrusions 14. Therefore, a DLC film is formed on the surface of the permanent magnet body 1, but no DLC film is formed on the exposed portion between the permanent magnet bodies 1.

  Further, after the DLC film is formed by such a method, if the connecting body 10 is cooled, the projection 14 contracts to the original state, so that the conductive wire body 2 can be easily extracted from the permanent magnet body 1, Only the magnetic health product 5 on which the DLC film is formed can be taken out. Moreover, if the insulating film 13 is peeled off from the extracted conductive wire 2, the conductive wire 2 can be reused.

  In this embodiment, in order to reuse the conductive wire 2, the insulating film 13 is coated on the portion excluding the protrusion 14. However, when there is no purpose of reuse, a conductive wire having a uniform diameter is used. It may be used to be locked to the permanent magnet body by thermal expansion of the conductive wire body. Further, without using thermal expansion, the permanent magnet body 1 may be penetrated through the conductive wire body by press fitting so that the permanent magnet body cannot be moved.

  In the various embodiments described above, the permanent magnet body 1 is exemplified as a spherical one. However, as shown in FIGS. 8A to 8C, the permanent magnet body 1 is a cylinder, an ellipsoid, or a truncated cone. Can also be used.

  If the permanent magnet body 1 is configured in such a shape, when the jig 20 shown in FIG. 1 or the like is used, the positioning of the through holes 1a can be easily performed, and the connection body 10 can be formed efficiently. 8A is a cross-sectional view showing a state where the permanent magnet body 1 is housed in the recess 21 of the jig 20. FIG.

  In the above embodiment, a description has been given of using a permanent magnet body as a bead member, but using a magnet material that is not magnetized as a bead member, a DLC film is formed on the magnet material in the same manner as described above, Thereafter, it may be magnetized to form a magnetic health product.
