In general, coinage is a kind of property that is used as a measure of economic value, a means of payment, a purpose of accumulation, and this coin is usually used as an intermediary of commodity exchange in the market economy .

In addition, coins are issued with different types and units according to each country, and when there are events that are characteristic of the country or region, various coins, medals, etc. (hereinafter referred to as "custom" Coins ") will be issued.

In addition, when a common coin or custom coin or the like is newly issued, it is made to be widely publicized in a single sample structure so as to be provided to each country or each country in the world.

The conventional coin promoting method, which is widely used, is to select the coin to be issued according to the type of the coin to be issued, so that the selected coin is randomly accommodated in the simple structure of the coin, To be provided to the respective currency authorities in each country or region in an individual form that does not exist.

In the conventional coin processing machine, coin processing, coin processing, coin processing, coin processing, coin processing, coin processing, coin processing, and so on are performed. The upper mold is moved by the ram, and then the lower mold is pushed out of the ring type die to take out the processed product. Therefore, the overall size is large and a very large pressure is required, There is a concern that a safety accident may occur during removal, and it is difficult to process a large number of workpieces in a short time.

In another conventional example, a conventional photolithography technique used in the field of printing is applied to manufacturing a latent image of a coin, and then copied onto a plummer printing plate using a film original including a latent image. Then, And a latent image coin is manufactured by applying a printing plate making technique to produce a latent image coin.

In the above-described conventional latent-image mold manufacturing method, a machine engraving machine is used in a NC engraver using a CAD used in a foreign country, or a latent image is sculpted into a number of pieces in order to emphasize an artistic image of the latent image. Thereby producing a coin.

This is because, first, a precision machine engraving machine is necessary for manufacturing by a mechanical engraving method, and a manufacturing method of a male engraving can give an artistic image of a latent image. However, since the manufacturing time of a latent image engraving takes a lot of time, There are problems and difficulties.

That is, the conventional coin adopts a casting method and an abstraction method, and the above-mentioned coining method is a method of manufacturing a coin-like manufacturing process and a coin to make a metal plate into a thin plate shape, Is manufactured in a gypsum plate and then sculpted into metal rods in a sieve size. Such a manufacturing method is suitable for mass production. Since the manufacturing cost is high in the unit production, it is practically necessary to manufacture customized custom coin for one person There is a problem.

Fig. 3 is a manufacturing process diagram of a custom coin according to the present invention; Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, a custom coin according to the present invention includes an insertion groove 12 having a predetermined depth at one end or both ends thereof, a coin frame 10 having a knurling 14 formed at a rim thereof, (20) inserted into the insertion groove (12) of the main body (10).

In addition, the custom coin includes a transparent or translucent coin capsule 30 in which an insertion space into which the custom coin is inserted is formed.

In addition, the coin capsule 30 includes a case 40 in which the coin capsule 30 with the custom coin inserted therein is housed for use as a gift or for storage.

The method of manufacturing a custom coin of the present invention includes a coin frame manufacturing step S1, a coin board manufacturing step S2 and an assembling step S3 as shown in Fig.

The coin frame manufacturing step (S1) is a step of manufacturing a coin frame of an external shape to have a general coin feel.

The metal frame manufacturing step S1 includes a metal frame shaping step S12, a knurling machining step S14, and a surface treatment step S16.

The coin shape machining step S12 is a step of shaping the primary coin frame by machining the base metal to fit the size of the custom coin to be manufactured.

This is to form the shape of a custom coin frame to be manufactured, and the size and thickness of the prepared coin frame are matched to the coin frame 10.

In this case, the material of the base material is formed of any one of metallic materials such as iron, copper, non-ferrous metal such as aluminum, or synthetic resin such as acrylic. Of course, the present invention is not limited thereto, and various materials can be used depending on the user or operator's choice.

In addition, a primary coin frame is formed by machining the insertion grooves 12 having a predetermined depth so that the coin plate is inserted into one end or both ends of the coin frame 10.

The knurling machining step S14 is a step of shaping the shape of the secondary coin frame by machining the knurling on the rim of the primary coin frame formed through the coin frame machining step S12.

This is because the knurling 14 is processed by the knurling machine on the rim of the primary coin frame to form the shape of the secondary coin frame. In some cases, the nulling ring 14 may be omitted.

The surface treatment step S16 is a step of shaping a shape of a coin frame by performing surface treatment on the shape of a secondary coin frame formed through the knurling process S14.

This is a surface plating treatment to improve the durability and the product value in the shape of the formed secondary coin frame. That is, due to the nature of the coin, plating is performed so as to have a texture such as gold or silver, thereby enhancing the product value as well as improving the durability of the shape of the coin frame.

The coin manufacturing step S2 is a step of forming a coin to be inserted into the insertion groove formed at one end or both ends of the coin frame shaped through the coin frame manufacturing step S1.

The coin manufacturing step S2 includes an outer design selecting step S22, an inserted image selecting and converting step S24, a 3D printing step S26, and a coating step S28.

The outline design selection step (S22) is a step of selecting an outline frame of a custom coin to be formed.

This selects the outline design of the shape desired by the user (or buyer). In some cases, it is possible to create a unique coin outer design by executing the drawing operation directly on the drawing or the site in the form desired by the user.

That is, the shape to be formed on the outer periphery of the coin is selected in order to utilize the characteristic of the coin. It may be omitted in some cases.

The inserted image selection and conversion step S24 is a step for the user to select an image to be inserted into the coin and convert it into a 3D stereoscopic design, thereby fixing the coin image.

In this case, the inserted image of the coin can utilize an existing image or an image owned by a user (or a buyer).

In addition, the inserted image selected by the user is a 2D plane, and is converted into a three-dimensional shape conforming to the characteristics of the coin. The 3D conversion can be performed simply and easily through a computer program.

Accordingly, the user selects an image to be inserted into the coin, converts the selected image into a 3D stereoscopic image, and stores the determined coin image in the computer.

The 3D printing step S26 is a step of forming the primary image through the 3D printer through the image selection and conversion step S24.

This is achieved by providing the determined image to the 3D printer, and then forming the primary coin through the 3D printer.

The coating step S28 is a step of processing the coating to improve the durability and the product value on the primary coin plate formed through the 3D printing step S26.

This can be achieved by subjecting the formed primary coin to a post-treatment such as fine grinding, plating, vapor deposition, nano or general spraying, or by gold foil, silver foil or lapping to improve the durability of the primary coin And the material feel of the coin. In this case, it can be plated so as to have the same or similar texture as that of the formed coin frame, or it can be formed to have a texture of different feeling, which can be selected according to the user's taste.

Meanwhile, the step of manufacturing the coin plate S2 is not limited to the step of forming the coin plate 20 by the 3D printer, and the casting method can be performed concurrently.

That is, in the 3D printing step (S26), a shape of a copper plate is formed through a 3D printer using a casting resin (or a resin wax) as a material, and the thus shaped copper plate is placed in a casting mold, When the casting mold is poured into the casting mold in such a manner, the casting resin is melted by the casting mold so that the casting mold is filled with the casting mold.

Then, the coin plate 20 is completed by subjecting the coin coin 20 thus formed to the coating step S28.

As a result, the coin plate 20 can be manufactured by either a direct molding method in which a coin plate is formed through a 3D printer, an indirect method in which a coin shape is formed using a casting resin, Lt; / RTI >

Of course, the present invention is not limited thereto, and any method can be used as long as it can easily manufacture a coin plate. For example, a carving method using a carving machine or the like may be used.

The assembling step S3 is a step of manufacturing a completed coin by inserting a coin plate molded through a coin manufacturing step S2 into a coin frame formed through the coin frame manufacturing step S1.

This is accomplished by inserting the formed coin 20 into the insertion groove 12 of the coin frame 10. In this case, after the adhesive is applied to the insertion groove 12, the coin 20 is adhered and fixed by the adhesive.

Meanwhile, the coin completed in the above manner can be inserted into the prepared coin capsule and stored in the case, thereby further improving the product value.

The above description is only one embodiment for implementing a custom coin manufacturing method using a 3D printer, and the present invention is not limited to the above-described embodiment. It will be understood by those skilled in the art that various changes may be made without departing from the spirit of the invention.
