Description

면발광 무드 조명용 부분 도금 처리된 자동차의 내장재 제조 방법{Manufacturing method for interior materials of automobiles with partial plating for surface-emitting mood lighting} Manufacturing method for interior materials of automobiles with partial plating for surface-emitting mood lighting {Manufacturing method for interior materials of automobiles with partial plating for surface-emitting mood lighting}

본 발명은 자동차의 내장재 제조 방법에 관한 것으로, 더욱 상세하게는 면발광 무드 조명부품을 제작하기 위해 부분 도금 처리된 자동차의 내장재를 성형하기 위한 방법에 관한 것이다.The present invention relates to a method for manufacturing an interior material of a vehicle, and more particularly, to a method for molding an interior material of a vehicle partially plated to produce a surface-emitting mood lighting component.

일반적으로 자동차의 내장재 중에서 면발광이 구현되는 무드 조명용 부품의 제조는 필요부위를 도금 처리하여 이루어진다. In general, the manufacture of parts for mood lighting in which surface light is realized among interior materials of automobiles is made by plating the necessary parts.

종래 부분도금 처리된 조명부품의 제조는 도금 처리가 가능한 도금성 소재와 빛 투사가 가능한 투광성 소재를 이중 사출하여 일체로 성형한 다음, 일체로 성형된 부품을 도금액에 침지하여 도금성 소재의 부위만을 도금 처리하는 과정으로 이루어지게 된다.In the conventional manufacturing of partially plated lighting parts, a plating material capable of plating and a translucent material capable of projecting light are double-injected to form one body, and then the integrally molded part is immersed in a plating solution to only the portion of the plating material. This is done through the plating process.

이러한 도금 과정에서 도금성 소재의 표면에는 도금 처리가 되고, 투광성 소재의 표면에는 도금 처리가 되지 않고 투광성을 유지할 수 있게 되므로, 소재의 배면에 조명모듈을 배치하여 빛을 조사하게 되면, 투광성 소재를 통해 외부로 빛이 발광하게 된다.In this plating process, the surface of the plated material is plated, and the surface of the light-transmitting material is not plated and the light-transmitting property can be maintained. light is emitted to the outside.

그런데 상기와 같은 일련의 과정을 통해 부분도금 처리된 조명부품을 제조하는 방법에서는 다음과 같은 문제를 초래하게 된다.However, the method of manufacturing a partially plated lighting component through a series of processes as described above causes the following problems.

첫째, 도금 처리가 가능한 도금성 소재와 빛 투사가 가능한 투광성 소재를 일체로 성형하기 위해서는 이중사출 전용 사출설비가 필요하게 되는 데, 이중사출설비는 동일 사이즈의 성형품을 기준으로 일반사출기와 비교할 때 크기와 비용적인 측면에서 경제적 부담이 크게 상승하게 되고, 사출금형 또한 2벌 세트로 정밀 제작되어야 하기 때문에 금형 제작비 또한 크게 상승하게 되므로, 버튼류의 소형부품에 한정하여 적용되는 실정이다.First, in order to integrally mold a plated material that can be plated and a translucent material that can project light, an injection facility dedicated to double injection is required. In terms of cost and cost, the economic burden is greatly increased, and since the injection mold must be precisely manufactured in two sets, the mold manufacturing cost also increases significantly, so it is applied only to small parts such as buttons.

둘째, 첫 번째와 같은 문제를 해결하고자 일반사출물의 도금 처리된 표면을 레이저 에칭하여 구현하고자 하였으나, 도금용 플라스틱 소재(도금 ABS)는 불투명 소재로 투광이 안 되기 때문에, PC 등의 투광소재에 일반적인 습식도금이 아닌 증착도금 처리하여 도금면을 레이저 에칭으로 미세 타공하게 되는 데, 이러한 미세 타공시에는 타공홀로 빛의 투광은 가능하지만 레이저 타공부위가 육안으로 보이는 문제점과 습식도금 대비 증착도금처리 비용이 상승하는 문제를 야기하게 된다.Second, in order to solve the same problem as in the first one, the plated surface of the general injection material was laser etched to realize it, but the plastic material for plating (plated ABS) is an opaque material and does not transmit light. The plated surface is micro-perforated by laser etching rather than wet plating. In this micro-perforation, light can be transmitted through the perforated hole, but the laser perforation area is visible to the naked eye, and the deposition plating cost is higher compared to wet plating. raises problems.

셋째, 이중사출의 경우 PC소재 성형 금형의 가공 시 가공공구 형상에 의해 형상 구현에 대한 제약이 발생하여 미세한 조명 패턴부 가공 및 날카로운 엣지 처리에 한계가 있게 된다.Third, in the case of double injection, there is a limitation in the shape realization due to the shape of the processing tool when processing the PC material molding mold, so there is a limit to processing the fine lighting pattern part and processing the sharp edge.

넷째, 이중사출 시 PC와 ABS는 재질 특성상 화학결합이 되지 않기 때문에 두 소재간 완전 접합이 되지 않아서 소재 경계부에 도금 전처리액이 침투되어 도금 불량이 자주 발생하는 문제를 초래하게 된다.Fourth, during double injection, since PC and ABS do not chemically bond due to the characteristics of the material, complete bonding between the two materials does not occur, and the plating pretreatment solution penetrates the material boundary, causing frequent plating defects.

본 발명이 해결하고자 하는 기술적 과제는 면발광 무드 조명부품의 제작을 위해 부분 도금 처리된 자동차의 내장재를 성형함에 있어 이중사출 등의 전용 사출설비없이 범용 사출기를 이용하여 기재의 성형을 보다 용이하게 구현할 수 있는 개선된 자동차의 내장재 제조 방법을 제공하는 것이다.The technical problem to be solved by the present invention is to more easily implement the molding of the substrate using a general-purpose injection machine without special injection equipment such as double injection in molding the interior material of a partially plated automobile for the production of surface-emitting mood lighting parts. It is to provide an improved method for manufacturing interior materials for automobiles.

상기와 같은 기술적 과제를 해결하기 위한 본 발명은 도금성 소재와 투광성 소재를 층상으로 배치하여 적층소재를 형성하는 소재준비 공정, 상기 소재준비 공정에서 준비된 적층소재에 대해 투광부위를 외부로 노출되게 하는 표면처리 공정, 상기 표면 처리된 적층소재를 프리포밍하는 프리포밍 공정, 상기 프리포밍된 성형품에 투광성 소재를 인서트 사출성형하여 투광층을 형성하는 사출성형 공정, 및 상기 사출성형된 성형품에 대해 도금 처리하여 도금층을 형성하는 도금 공정을 포함하고, 상기 도금 공정은 상기 사출성형된 성형품에서 투광부위를 제외한 나머지 비투광부위만을 도금 처리하도록 구성되는 것이 바람직하다. The present invention for solving the above technical problems is a material preparation process for forming a laminated material by arranging a plated material and a light-transmitting material in layers, exposing the light-transmitting part to the outside for the laminated material prepared in the material preparation process A surface treatment process, a preforming process of preforming the surface-treated laminated material, an injection molding process of insert-injection molding a light-transmitting material into the preformed molded article to form a light-transmitting layer, and plating treatment on the injection-molded article to include a plating process to form a plating layer, and the plating process is preferably configured to plated only the non-transmissive portion of the injection-molded article except for the light-transmitting portion.

In an embodiment of the present invention, the plating material capable of plating in the laminate material prepared in the material preparation process is ABS, and the light transmitting material capable of projecting light is preferably composed of PC.

본 발명의 실시예로서, 상기 표면처리 공정은 적층소재에 대해 투광부위만을 외부로 노출되게 하는 레이저 에칭 또는 레이저 컷팅으로 이루어지는 것이 바람직하다. In an embodiment of the present invention, the surface treatment process is preferably made of laser etching or laser cutting to expose only the light-transmitting portion to the outside with respect to the laminated material.

본 발명의 실시예로서, 상기 프리포밍 공정을 거친 성형품에 대해 투광성 소재를 인서트 사출성형하여 투광층을 형성하기 이전 공정에서 프리포밍된 성형품의 가장자리 부위를 다듬어 주는 트리밍 공정을 더 포함하여 구성되는 것이 바람직하다. As an embodiment of the present invention, a trimming process of trimming the edge of the molded article preformed in the process prior to forming the light-transmitting layer by insert injection molding a light-transmitting material into the molded article that has undergone the pre-forming process is configured to further include desirable.

본 발명의 실시예로서, 상기 사출성형 공정은 상기 프리포밍 공정에서 프리포밍된 성형품을 인서트 사출금형의 내부에 안착시킨 다음, 프리포밍된 성형품을 구성하는 적층소재 중에서 투광성 소재의 표면에 대해 별도의 투광수지를 사출하여 투광층을 형성하여 이루어지는 것이 바람직하다. As an embodiment of the present invention, in the injection molding process, the molded article preformed in the preforming process is seated inside the insert injection mold, and then a separate light-transmitting material is applied to the surface of the light-transmitting material among the laminated materials constituting the preformed molded article. It is preferable to form a light-transmitting layer by injecting a light-transmitting resin.

본 발명의 실시예로서, 상기 사출성형 공정에서 형성되는 투광층의 구조적 강성은 상기 소재준비 공정에서 형성되는 적층소재의 구조적 강성 보다 크게 설정되는 것이 바람직하다. In an embodiment of the present invention, the structural rigidity of the light-transmitting layer formed in the injection molding process is preferably set to be greater than the structural rigidity of the laminated material formed in the material preparation process.

본 발명의 실시예로서, 상기 사출성형 공정에서 형성되는 투광층의 두께는 상기 소재준비 공정에서 형성되는 적층소재의 두께 보다 크게 설정되는 것이 바람직하다. In an embodiment of the present invention, the thickness of the light-transmitting layer formed in the injection molding process is preferably set to be larger than the thickness of the laminate material formed in the material preparation process.

본 발명의 실시예로서, 상기 사출성형된 성형품에 대해 비투광부위를 도금 처리하는 도금 공정은 습식도금 공정으로 이루어지는 것이 바람직하다. In an embodiment of the present invention, the plating process of plating the non-transmissive portion of the injection-molded article is preferably a wet plating process.

본 발명의 실시예로서, 상기 도금 공정을 거친 성형품 중에서 투광층의 표면에 대해 도광판 및 LED가 실장된 PCB를 조립하는 조립 공정을 더 포함하여 구성되는 것이 바람직하다. As an embodiment of the present invention, it is preferable to further include an assembly process of assembling the PCB on which the light guide plate and the LED are mounted on the surface of the light transmitting layer among the molded products that have undergone the plating process.

본 발명의 실시예에 따른 면발광 무드 조명용 부분 도금 처리된 자동차의 내장재 제조 방법은 다음과 같은 효과를 제공한다.The method for manufacturing the interior material of a partially plated automobile for surface-emitting mood lighting according to an embodiment of the present invention provides the following effects.

첫째, 이중사출 등의 전용 사출설비없이 범용 사출기로 기재의 성형을 가능하게 한다.First, it enables molding of the substrate with a general-purpose injection machine without dedicated injection equipment such as double injection.

둘째, 합지된 필름에 대해 레이저 에칭으로 도금 처리가 가능한 도금성 소재를 컷팅할 수 있으므로, 미세한 조명 패턴 및 날카로운 엣지 처리가 가능하여 다양한 형태의 조명패턴을 디자인함에 있어 제약이 없게 된다.Second, since a plated material that can be plated by laser etching can be cut on the laminated film, a fine illumination pattern and sharp edge treatment are possible, so that there is no restriction in designing various types of illumination patterns.

셋째, 투광층의 형성을 위한 투광수지에 대한 다양한 종류의 칼라 변경이 가능하므로 조명이 인가되지 않을 경우에도 조명 패턴부에서 외부로 들어나는 색감에 대해 다양성을 줄 수 있게 된다.Third, since various types of colors of the light transmitting resin for forming the light transmitting layer can be changed, it is possible to give diversity to the color emitted from the lighting pattern part to the outside even when no light is applied.

넷째, 도금 처리가 가능한 도금성 소재와 빛 투사가 가능한 투광성 소재를 완전한 상태로 접합시킨 합지된 필름을 이용하여 조명부품용 성형품을 제작할 수 있으므로, 도금 공정에서 전처리액이 도금성 소재의 제거부위를 통해 도금성 소재와 투광성 소재 사이의 틈새로 침투하지 못하게 되고, 이를 통해 도금 공정에서의 불량률 발생 정도를 크게 줄일 수 있게 된다.Fourth, since a molded article for lighting parts can be manufactured using a laminated film in which a plating material capable of plating and a translucent material capable of projecting light are bonded in a complete state, the pretreatment solution removes the plating material from the plating process. Through this, it is impossible to penetrate into the gap between the plating material and the light-transmitting material, and through this, the occurrence of defective rate in the plating process can be greatly reduced.

도 3을 참조로 하면, 본 발명의 실시예에 있어, 사출성형 공정은 앞선 프리포밍 공정과 트리밍 공정을 거쳐 제작된 성형품(30)을 인서트 사출금형(40)의 내부에 인서트한 다음, 금형의 캐비티 내부로 투광성 소재인 투광수지를 사출하여 투광층(50)을 일체로 성형하는 일련의 작업과정을 의미한다. Referring to FIG. 3 , in the embodiment of the present invention, the injection molding process inserts the molded article 30 manufactured through the preceding preforming process and trimming process into the insert injection mold 40, and then the mold It refers to a series of work processes for integrally molding the light-transmitting layer 50 by injecting a light-transmitting resin, which is a light-transmitting material, into the cavity.

즉, 사출성형 공정은 프리포밍 및 트리밍된 성형품(30)의 배면에 대해 투광수지를 사출하여 잉여의 투광층(50)을 두께방향으로 일체로 형성하는 일련의 작업과정에 해당하는 것이다.That is, the injection molding process corresponds to a series of work processes for integrally forming the excess light-transmitting layer 50 in the thickness direction by injecting the light-transmitting resin onto the back surface of the preformed and trimmed molded article 30 .

이를 위해 사출성형 공정은 프리포밍 및 트리밍된 성형품(30)을 인서트 사출금형(40)의 내부에 안착시킨 다음, 성형품(30)을 구성하는 적층소재 중에서 투광성 소재인 하지(12)의 표면에 대해 별도의 투광수지를 금형의 주입구(41)로 사출하여 투광층(50)을 부가적으로 형성함으로써 구현될 수 있다. 또한, 도 3에서 미설명 부호 42는 사출성형 공정에서 인서트 사출금형(40)의 캐비티 내부의 압력을 외부로 빼기 위해 진공압이 작용하는 에어빼기 통로인 것이다.To this end, in the injection molding process, the preformed and trimmed molded article 30 is seated inside the insert injection mold 40, and then, among the laminated materials constituting the molded article 30, the light-transmitting material of the base 12 for the surface of the It can be implemented by injecting a separate light-transmitting resin into the injection hole 41 of the mold to additionally form the light-transmitting layer 50 .

It would be desirable to set it larger.

즉, 본 발명의 실시예에 따른 사출성형 공정에서 형성되는 투광층(50)은 자동차 내장재의 구조적 강성을 확보하기 위한 코어층에 해당하는 것으로, 투광층(50)의 구조적 강성은 적층소재인 합지된 필름(10)의 구조적 강성 보다 크게 설정됨으로써, 무드 조명용 제품의 강성은 적정의 수준으로 보장받을 수 있게 된다.That is, the light-transmitting layer 50 formed in the injection molding process according to the embodiment of the present invention corresponds to a core layer for securing the structural rigidity of an automobile interior material, and the structural rigidity of the light-transmitting layer 50 is laminated material. By setting it to be larger than the structural rigidity of the film 10, the rigidity of the product for mood lighting can be guaranteed at an appropriate level.

It refers to a series of work processes.

이 경우, 도금층(60)은 사출성형된 성형품(30)에서 투광부위를 제외한 나머지 비투광부위만을 도금 처리하도록 구성된다. In this case, the plating layer 60 is configured to plated only the non-transmissive portion other than the light-transmitting portion in the injection-molded article 30 .

즉, 도금 처리공정은 필름(10)을 구성하는 상지(11)와 하지(12) 중에서 도금성 소재에 해당하는 상지(11)의 표면에 한정하여 도금이 실시되는 일련의 작업과정인 것이다.That is, the plating process is a series of work processes in which plating is limited to the surface of the upper extremity 11 corresponding to the plating material among the upper extremities 11 and 12 constituting the film 10 .

또한, 본 발명의 실시예에 있어, 도금 공정은 사출성형된 성형품(30)에 대해 비투광부위만을 도금 처리하는 것으로, 예컨대 습식도금 공정을 그 예로 들 수 있을 것이다.In addition, in the embodiment of the present invention, the plating process involves plating only the non-transmissive portion of the injection-molded molded article 30 , for example, a wet plating process may be exemplified.

도 5는 본 발명의 실시예에 따른 자동차의 내장재 제조 방법에 있어, 도금 공정을 거친 성형품의 투광층 배면에 도광판과 LED가 실장된 PCB을 조립하는 조립 공정을 설명하기 위한 도면이다.FIG. 5 is a view for explaining an assembly process of assembling a PCB on which a light guide plate and an LED are mounted on the rear surface of a light transmitting layer of a molded article that has undergone a plating process in the method for manufacturing an interior material of a vehicle according to an embodiment of the present invention.

도 5를 참조로 하면, 본 발명의 실시예에 있어, 조립 공정은 앞선 도금 공정에서 도금층(60)이 형성되게 제작되는 성형품(30)의 배면, 즉 투광층(50)의 표면에 대해 도광판(70)과 LED가 실장된 PCB(80)을 각각 적정의 위치에 조립하는 일련의 작업과정을 의미한다. 이 경우, LED가 실장된 PCB(80)는 광원에 해당하는 것으로, 반드시 LED에 한정되는 것이 아니라, 빛을 외부로 조사할 수 있는 광원이라면 어느 것이라도 무방할 것이다.5, in the embodiment of the present invention, in the assembly process, the light guide plate ( 70) and the LED-mounted PCB 80 refer to a series of work processes for assembling each at appropriate positions. In this case, the PCB 80 on which the LED is mounted corresponds to a light source, and is not necessarily limited to the LED, and any light source capable of irradiating light to the outside may be used.

이 결과, PCB(80)의 광원으로부터 조사되는 빛은 도광판(70)을 통해 확산된 다음, 투광층(50)과 투광성 소재인 하지(12)를 거쳐 외부로 방사될 수 있게 된다. As a result, the light irradiated from the light source of the PCB 80 is diffused through the light guide plate 70 , and then can be radiated to the outside through the light transmitting layer 50 and the base 12 , which is a light transmitting material.

또한, PCB(80)의 광원으로부터 조사되는 빛 중에서 투광층(50)과 하지(12)를 거쳐 비투광성인 도금성 소재의 상지(11)로 조사되는 빛은 차단되어 외부로 방사될 수 없음은 물론이다. In addition, among the light irradiated from the light source of the PCB 80, the light irradiated to the upper extremity 11 of the non-transmissive plating material through the transmissive layer 50 and the lower extremity 12 is blocked and cannot be radiated to the outside. Of course.
