Figure 2 (a) is a vertical cross-sectional view of a portable terminal injection molded insert the antenna according to an embodiment of the present invention, Figure 2 (b) is a portable terminal injection molded insert of the antenna except the reinforcing layer in Figure 2 (a) Vertical cross section.

The portable terminal injection molded product injected with the antenna according to the embodiment of the present invention includes an injection material 100 and an antenna part 200.

The injection-molded material 100 refers to a composition of a synthetic resin material forming a portable terminal, and may be a main body cover C1, a battery protective cover C2, an antenna carrier, or the like of the portable terminal.

The battery protective cover (C2) is mounted on the body cover of the portable terminal serves to protect the battery, the antenna carrier means a component that is mounted on the portable terminal with the antenna itself.

One surface of the injection molded product 100 is mounted on the main body cover C1 of the portable terminal to protect the inside of the portable terminal.

The injection molded product 100 is made of synthetic resin such as ABS (Acrylonitrile-butadiene-styrene copolymer), PC (Polycarbonate), etc., and is integrally formed together with the antenna unit 200.

The antenna unit 200 includes a film layer 210, a radiator 220, a printing layer 230, a coating layer 240, a reinforcing layer 250, and an adhesive layer 260.

The film layer 210 is bonded to the injection molding 100.

At this time, the film layer 210 may be coupled to the inner surface or the outer surface of the injection molding 100 as necessary.

The film layer 210 is made of PET or PC, and is formed in a thin plate shape.

The film layer of the conventional film antenna is usually made of PI (Polyimide), but since PI has a high deformation temperature, it is not only very difficult to deform the film layer to match the shape of the injection molded product, but also to deform after deforming the shape. It is also difficult to maintain the shape.

In contrast, PET or PC is easy to deform the shape because the deformation temperature is relatively low.

Accordingly, when the antenna unit 200 is integrally molded together with the injection molding 100, the shape of the film layer 210 may be easily modified to match the shape of the injection molding 100.

 The radiator 220 is formed on one surface of the film layer 210 and is disposed between the film layer 210 and the injection molding 100.

The radiator 220 is disposed between the film layer 210 and the injection molding 100 and bonded to the film layer 210 by an ultraviolet curing adhesive (B).

The radiator 220 may be in contact with the film layer 210 using various adhesives, but is preferably bonded by using an ultraviolet curing adhesive (B).

Specifically, the radiator 220 is coated with a corrosion solution on the surface of the copper plate or SUS plate bonded to the film layer 210 by the ultraviolet curing adhesive (B) to the rest other than the pattern previously printed on the copper plate or SUS plate It is formed by corrosion of parts.

Conventional film antennas have formed a radiator using conductive ink, but this method has a problem that it is difficult to precisely form a small integrated radiator.

However, in the related art, since the copper layer or the SUS plate bonded to the film layer 210 and the film layer 210 is bonded using a thermosetting bond or a double-sided tape, the surface of the copper plate or the SUS plate is corroded using a corrosion solution. When the radiator 220 is formed, there is a problem that the thermosetting bond or the double-sided tape reacts with the corrosion solution and the radiator 220 is not fixed to the film layer 210 and is pushed out.

In addition, since the double-sided tape does not withstand the injection temperature when inserting the injection molded product 100 and the antenna unit 200 integrally, it is difficult to bond and fix the film layer 210 and the radiator 220.

Due to this problem, in the present embodiment, the film layer 210 and the radiator 220 are bonded and fixed stably with an ultraviolet curing adhesive (B) having chemical resistance.

The print layer 230 is formed on the other surface of the film layer 210, which is the opposite surface on which the radiator 220 is disposed based on the film layer 210.

The printing layer 230 may be made of various colors or patterns to express the surface of the injection molding 100 beautifully. When the film layer 210 is bonded to the outer surface of the injection molding, the printing layer 230 may be used. Various patterns constituting the exposed to the outside from the surface of the injection molding 100 can obtain the effect of improving the appearance.

In FIGS. 4 and 5, the film layer 210 is bonded to the outer surface of the injection molding 100 and the print layer 230 is exposed to the outside, thereby forming a color or pattern on the surface of the injection molding 100. The surface of the mobile terminal is beautifully expressed through the printed layer 230.

Of course, the film layer 210 may be coupled to the inner surface of the injection molded product 100.

And since the printing layer 230 is formed on the opposite side of the surface in which the injection molding 100 is molded in the film layer 210, the injection printing layer 230 is injection pressure when the injection molding of the injection molding 100 Can be prevented from being damaged.

Therefore, as described below, since the thickness of the reinforcement layer 250 or the reinforcement layer 250 does not have to be formed, the entire thickness of the antenna part 200 may be reduced, and the injection molded part 100 and the antenna part may be reduced. It is easy to form 200 integrally.

The coating layer 240 is applied to the other surface of the film layer 210 on which the printing layer 230 is formed to protect the printing layer 230.

The reinforcement layer 250 is disposed on one surface of the film layer 210 in which the radiator 220 is formed.

Specifically, the reinforcement layer 250 is that the antenna unit 200 is damaged by the injection pressure of the synthetic resin molded into the injection molding 100 when the insert injection molding the antenna unit 200 and the injection molding 100 integrally prevent.

In the present embodiment, the print layer 230 is the weakest part of the injection pressure, but the print layer 230 is opposite to the surface on which the radiator 220 is disposed in the film layer 210, that is, the injection molded material 100. ) Is formed on the opposite side of the surface to be molded to minimize damage due to the injection pressure, so that the thickness of the reinforcement layer 250 is not thinned or the reinforcement layer 250 is not disposed as shown in FIG. It may not.

The print layer 230 is an ink for expressing a color or a pattern on the surface of the injection molding 100, and may be easily damaged by the injection pressure because it is formed as a thin film in the film layer 210.

However, since the film layer 210 is made of synthetic resin such as PET or PC and can withstand the injection pressure, when the injection molding 100 and the antenna unit 200 are integrally molded, the injection molding 100 and the printing layer ( Disposed between the 230 to protect the print layer 230 from the injection pressure.

The adhesive layer 260 is formed on one surface of the reinforcement layer 250 in which the injection molding material 100 is disposed to bond the injection molding material 100 to the antenna part 200.

Specifically, the adhesive layer 260 is formed on one surface of the reinforcement layer 250 and is molded into the injection molding 100 when the antenna unit 200 is integrally molded together with the injection molding 100 by insert injection. In contact with the synthetic resin it is strongly bonded to the antenna unit 200 and the injection molding (100).

On the other hand, when the film layer 210 and the injection molding 100 are made of the same material, the film layer 210 and the injection molding 100 may be integrally formed without bonding the adhesive layer 260.

3 is a flowchart illustrating a method of manufacturing an injection molded product for inserting an antenna according to an exemplary embodiment of the present invention, and FIG. 4 is a perspective view of a portable terminal in which an antenna unit is integrally formed in a battery protection cover according to an exemplary embodiment of the present invention. 5 is a perspective view of a portable terminal in which an antenna unit according to an embodiment of the present invention is integrally formed on a body cover.

According to an embodiment of the present invention, a method of manufacturing an injection molded product for inserting a film antenna into a portable terminal includes an antenna unit forming step and an injection molding step (S90).

The antenna unit forming step forms the antenna unit 200 as described above.

Specifically, the antenna unit forming step, lamination step (S10), pattern printing step (S20), etching step (S30), degreasing step (S40), reinforcing layer forming step (S50), adhesive layer forming step (S60), shape printing It consists of a step (S70) and the coating layer forming step (S80).

One surface described below is a lower surface based on FIG. 2, and the other surface is an upper surface based on FIG. 2.

The lamination step S10 combines the plate-like thin film layer made of copper or SUS to one surface of the film layer 210 made of polyethylene terephthalate (PET) or polycarbonate (PC) using an ultraviolet curing bond.

When the ultraviolet curable adhesive (B) is irradiated with ultraviolet rays, the photoreaction initiator in the adhesive reacts and cures in a few seconds to bond the film layer 210 and the thin film layer.

And the ultraviolet curing adhesive (B) has a chemical resistance to the corrosion solution.

Accordingly, even when the corrosion solution is applied to the thin film layer in the etching step (S30) described later, the UV-curable adhesive (B) does not cause a chemical reaction with the corrosion solution, so that the thin film layer and the film layer 210 are bonded to each other. It can be kept stable.

Conventionally, while bonding the thin film layer and the film layer 210 with a thermosetting bond or double-sided tape, the thermosetting bond or double-sided tape reacts with the corrosive solution in the etching step (S30) so that the adhesive force between the thin film layer and the film layer 210 is increased. It will fall, the problem that the thin film layer is pushed without being fixed to the film layer 210 occurs.

However, in this embodiment, by bonding the thin film layer and the film layer 210 with the ultraviolet curing adhesive (B), the bonding state with the film layer 210 is stable without the thin film layer is pushed out in the etching step (S30). It could be maintained as.

The pattern printing step (S20) prints a pattern on the thin film layer bonded to the film layer 210.

In addition, the etching step (S30) by applying a corrosion solution to the thin film layer to corrode the remaining portion except the portion where the pattern is printed to form a radiator 220 matching the pattern on one surface of the film layer 210.

As described above, since the thin film layer is bonded to the film layer 210 by an ultraviolet curing adhesive (B) having chemical resistance, the thin film layer is stably fixed and bonded to the film layer 210 in the etching step (S30). State can be maintained.

The degreasing step (S40) removes foreign matters from the radiator 220 and the film layer 210 after the etching step (S30).

The reinforcing layer forming step (S50) forms a reinforcing layer 250 on one surface of the film layer 210 in which the radiator 220 is formed after the degreasing step (S40).

As described above, when the antenna layer 200 and the injection molding 100 are integrally formed, the reinforcing layer 250 is damaged by the injection pressure of the synthetic resin molded into the injection molding 100. To prevent them.

In addition, when the reinforcing layer 250 is not formed on one surface of the film layer 210, the reinforcing layer forming step S50 may be omitted.

The adhesive layer forming step (S60) forms the adhesive layer 260 on one surface of the antenna unit 200 in contact with the injection molding 100 after the degreasing step (S40).

In the adhesive layer forming step (S60), the adhesive layer 260 is formed on one surface of the reinforcing layer 250 in which the injection molded product 100 is disposed.

When the reinforcement layer forming step S50 is omitted and the reinforcement layer 250 is not formed, the adhesive layer 260 may be formed on one surface of the film layer 210 in which the radiator 220 is formed.

In addition, when the material of the film layer 210 and the injection molding 100 are the same, the adhesive layer forming step (S60) may be omitted, and thus the adhesive layer 260 may not be formed.

The adhesive layer 260 facilitates bonding of the injection molding 100 and the film layer 210 when the injection molding 100 and the film layer 210 are made of different materials.

In the shape printing step (S70), after the adhesive layer forming step (S60), the printing layer 230 is formed on the other surface of the film layer 210 to which a thin film layer made of copper or SUS is combined.

The print layer 230 expresses color or pattern on the surface of the injection molded product 100.

The coating layer forming step (S80) forms a coating layer 240 on the other surface of the film layer 210 on which the printing layer 230 is formed.

The coating layer 240 is formed on the other surface of the film layer 210 and covers the print layer 230 to protect the print layer 230.

In the injection molding step S90, after the coating layer 230 is formed on the antenna unit 200, the antenna unit 200 is integrally formed on the injection molding unit 100 by insert injection.

In the injection molding step S90, the injection molding 100 is integrally formed with the antenna unit 200 to be in contact with the adhesive layer 260.

Specifically, the antenna unit 200 formed as described above is disposed inside the mold for molding the injection molded product 100, and the synthetic resin molded into the injection molded product 100 is formed in the mold housing provided with the antenna unit 200. The injection molded product 100 is integrally molded together with the antenna unit 200 by injecting it into the inside.

However, unlike the present invention, when the printed layer 230 is formed on one surface of the film layer 210 in which the radiator 220 is formed in the direction in which the injection is placed, not the other surface of the film layer 210, the antenna When injection molding the injection molding 100 together with the part 200, the synthetic resin injected into the mold die penetrates the adhesive layer 260 by the injection pressure and damages the printing layer 230.

In order to prevent damage to the printed layer 230 as described above, the reinforcement layer 250 should be formed thick so that the synthetic resin does not reach the printed layer 230, but the overall thickness of the antenna unit 200 is thick. Losing problems will occur.

Due to such a problem, in the present embodiment, the print layer 230 is formed on the other surface of the film layer 210, which is the opposite surface to the surface on which the injection molding 100 is disposed.

Accordingly, when the antenna unit 200 is integrally molded together with the injection molded product 100, the injection layer 100 and the antenna part 200 may be easily molded together by preventing damage to the printed layer 230. Can be.

As shown in FIG. 4, when the injection molded product 100 is the battery protection cover C2, the antenna unit 200 integrally molded by insert injection into the battery protection cover C2 may be NFC (Near field communication). It can be used as an antenna to perform electronic payment, P2P, card reader functions.

In addition, when the injection molded product 100 is the main body cover C1, a display unit is formed on the front surface of the main body cover C1, the battery protective cover C2 is mounted on the rear surface, and the antenna unit 200 is It may be integrally formed on the back of the body cover (C1), wherein the antenna unit 200 may be used as an NFC antenna or a main antenna for communication.

In FIGS. 4 and 5, the antenna unit 200 is shown, but the antenna unit 200 is not actually exposed, and the film layer 210 is bonded to the outer surface of the injection molding 100 when the antenna unit 200 is exposed. The printed layer 230 is shown to the outside.
