엘이디 모듈 어셈블리, 그리고 그 제조장치 및 제조방법{LED MODULE ASSEMBLY, MANUFACTURING APPARATUS AND MANUFACTURING METHOD THEREOF}LED module assembly, manufacturing apparatus and manufacturing method therefor {LED MODULE ASSEMBLY, MANUFACTURING APPARATUS AND MANUFACTURING METHOD THEREOF}

본 발명은 엘이디 모듈 어셈블리, 그리고 그 제조장치 및 제조방법에 관한 것으로, 특히 제품의 소형화가 가능한 엘이디 모듈 어셈블리, 그리고 그 제조장치 및 제조방법에 관한 것이다.
The present invention relates to an LED module assembly, a manufacturing apparatus and a manufacturing method thereof, and more particularly, to an LED module assembly capable of miniaturization of a product, and a manufacturing apparatus and a manufacturing method thereof.

엘이디(LED)는 발광소자(light-emitting diode)를 의미하며, 반도체의 p-n 접합구조를 이용하여 주입되는 소수 캐리어들의 재결합에 의하여 발광시키는 소자를 지칭한다. 현재까지 LED의 소재로는 발광 효율과 p-n 접합제작의 용이성 등으로 인하여 비소화갈륨(GaAs), 인화갈륨(GaP), 갈륨-비소-인, 갈륨-알루미늄-비소, 인화인듐(InP) 등 3B 및 5B족인 2원소 또는 3원소 화합물 반도체가 일반적으로 사용되고 있다.LED refers to a light-emitting diode, and refers to a device that emits light by recombination of minority carriers injected using a p-n junction structure of a semiconductor. To date, LED materials include 3B such as gallium arsenide (GaAs), gallium phosphide (GaP), gallium-arsenide-phosphorus, gallium-aluminum-arsenide, and indium phosphide (InP) due to light emission efficiency and ease of pn junction manufacturing. And 5 element group 2 or 3 element compound semiconductors are generally used.

엘이디는 종래의 광원과 비교하여 소형이고, 수명은 길며, 전기에너지가 빛에너지로 직접 변환하기 때문에 전력이 적게 들고 효율이 좋다. 뿐만 아니라 고속응답이므로 자동차 계기의 표시소자, 광통신용 광원 등 다양한 전자기기의 표시용 램프, 숫자표시 장치나 계산기의 카드 판독기 등에 널리 응용되고 있다.LEDs are smaller than conventional light sources, have a long lifetime, and have low power and good efficiency because electrical energy is directly converted into light energy. In addition, since it is a high-speed response, it is widely applied to display devices of automobile instruments, display lamps of various electronic devices such as optical communication light sources, numeric display devices, and card readers of calculators.

일반적으로 엘이디는 엘이디 모듈 어셈블리를 통하여 조립되어 광고판 및 각종 조명장치에서 광원으로 사용되는데, 도 1은 종래의 엘이디 모듈 어셈블리를 나타낸 단면도이고, 도 2는 도 1에 도시된 본체와 전선의 결합형태를 나타낸 평면도이다.In general, the LED is assembled through the LED module assembly is used as a light source in the billboard and various lighting devices, Figure 1 is a cross-sectional view showing a conventional LED module assembly, Figure 2 is a coupling form of the main body and the wire shown in Figure 1 It is the top view shown.

After inserting the PCB 10 between the two molds 110 and 120 as described above and bringing the two molds 110 and 120 into close contact with each other, the molding liquid is injected through the molding liquid injection hole 125 of the upper mold 120. When injected, as shown in FIG. 8, the molding liquid fills the PCB insertion grooves 111 and 121 formed in the two molds 110 and 112 through the dispersion grooves 112. At this time, the molding liquid is coated while covering the remaining portion except the upper surface of the LED 11 to form a waterproof layer 30.

도 9는 본 발명의 바람직한 실시예에 따른 엘이디 모듈의 제조방법을 나타낸 공정도이고, 도 10은 가압기를 이용해 전선체결용 튜브를 압착하는 모습을 나타내는 도면.9 is a process chart showing a manufacturing method of the LED module according to a preferred embodiment of the present invention, Figure 10 is a view showing a state of pressing the tube for wire fastening using a pressurizer.

본 발명의 바람직한 실시예에 따른 엘이디 모듈의 제조방법은, (a) 전선 체결용 튜브(20)를 안착시키는 단계(S10)와, (b) 전선 체결용 튜브(20)에 전선(40)(41)을 인입시키는 단계(S20)와, (c) 전선 체결용 튜브(20)를 압착시키는 단계(S30), 및 (d) 방수층(30)을 형성하는 단계(S40)를 포함한다.Method of manufacturing an LED module according to a preferred embodiment of the present invention, (a) the step of mounting the wire fastening tube 20 (S10), (b) the wire fastening tube 20 to the wire 40 ( 41, the step (S20), the (c) crimping the wire fastening tube 20 (S30), and (d) forming a waterproof layer 30 (S40).

상기 (a) 단계에서는 동으로 제작된 전선 체결용 튜브(20)를 PCB(10)의 상면 전후단부에 각각 안착시키게 된다. 이 과정에서 전선 체결용 튜브(20)는 표면실장방식(SMD방식)에 의해 PCB(10)의 상면에 안착된다. 즉, PCB(10)의 상면에 액체납을 페인팅한 후 액체납이 페인팅된 부분에 전선 체결용 튜브(20)를 안착시킨 후 고온상태인 곳을 통과시키게 되면, 전선 체결용 튜브(20)가 PCB(10)의 상면에 견고히 고정된다.In the step (a), the wire fastening tube 20 made of copper is mounted on the front and rear ends of the upper surface of the PCB 10, respectively. In this process, the wire fastening tube 20 is seated on the upper surface of the PCB 10 by a surface mounting method (SMD method). That is, after the liquid lead is painted on the upper surface of the PCB 10, the wire fastening tube 20 is seated on the portion where the liquid lead is painted, and then passed through a high temperature place. The upper surface of the PCB 10 is firmly fixed.

상기 (b) 단계에서는 전선 체결용 튜브(20)에 단부의 피복이 벗겨진 두 전선의 양단부를 각각 양쪽에서 삽입하게 된다. 이 때, 두 전선의 양단부는 서로 교차되게 삽입되는 것이 바람직하나 전선 체결용 튜브(20) 자체가 전원이 흐르기 때문에 교차되지 않아도 무방하다.In the step (b), both ends of the two wires, each of which is peeled off at the end of the wire fastening tube 20, are respectively inserted. At this time, it is preferable that both ends of the two wires are inserted to cross each other, but the wire fastening tube 20 itself may not cross because power is flowing.

상기 (c) 단계에서는 가압기(50)를 이용해 전선 체결용 튜브(20)의 상단을 압착시켜 두 전선이 전선 체결용 튜브(20)에 견고히 체결되도록 한다. 이 때, 가압기(50)는 펜치(pillers)의 형태로 형성되어 PCB(10)의 저면과 전선 체결용 튜브(20)의 상부를 가압하도록 되어 있다. 가압기(p)의 두 가압단 중 PCB(10)의 저면에 위치되는 가압단은 평면 형태이고 전선 체결용 튜브(20)의 상부를 가압하는 가압단은 요철형태로 형성된다. 그리고, 가압기(p)의 손잡이를 꽉 쥐더라도 두 가압단은 면접되지 않고 이격된다. 따라서, 가압기(p)의 두 가압단으로 PCB(10)와 전선 체결용 튜브(20)를 밀고 가압하면, PCB(10)는 변형되지 않고 전선 체결용 튜브(20)만 가압단의 형태에 맞게 요철 형태로 변형되어 전선 체결용 튜브(20) 내에 삽입된 두 전선(40)(41)을 전선 체결용 튜브(20) 내에 견고히 체결하게 된다.In the step (c) by pressing the upper end of the wire fastening tube 20 using the pressurizer 50 so that the two wires are firmly fastened to the wire fastening tube 20. At this time, the pressurizer 50 is formed in the form of pliers to pressurize the bottom of the PCB 10 and the upper portion of the wire fastening tube 20. Among the two pressing ends of the pressurizer p, the pressing end located on the bottom surface of the PCB 10 is in a planar shape, and the pressing end for pressing the upper part of the wire fastening tube 20 is formed in an uneven shape. In addition, even when the handle of the pressurizer p is gripped, the two pressurization stages are separated from each other without being interviewed. Therefore, when the PCB 10 and the wire fastening tube 20 are pushed and pressed by the two pressure ends of the pressurizer p, the PCB 10 is not deformed and only the wire fastening tube 20 is adapted to the shape of the pressure end. The two wires 40 and 41 inserted into the wire fastening tube 20 to be deformed into the uneven shape are firmly fastened into the wire fastening tube 20.

상기 (d) 단계에서는 두 몰드(110)(120) 사이에 PCB(10)를 삽입하고 두 몰드(110)(120)를 밀착시킨 후, 상부몰드(120)의 몰딩액 주입홀(125)을 통해 몰딩액을 주입하게된다. 몰딩액을 주입하면 몰딩액이 분산홈(112)을 통해 두 몰드(110)(120)에 형성된 PCB 삽입홈(111)(121) 및 전선 삽입홈(113)(122)을 채우게 된다. 이 때, 몰딩액은 LED(11)의 상면을 제외한 나머지 부분을 감싸면서 코팅되어 방수층(30)을 형성하게 된다.
In step (d), the PCB 10 is inserted between the two molds 110 and 120, the two molds 110 and 120 are brought into close contact with each other, and then the molding liquid injection hole 125 of the upper mold 120 is closed. Inject the molding liquid through. When the molding liquid is injected, the molding liquid fills the PCB insertion grooves 111 and 121 and the wire insertion grooves 113 and 122 formed in the two molds 110 and 120 through the dispersion grooves 112. At this time, the molding liquid is coated while covering the remaining portion except the upper surface of the LED 11 to form a waterproof layer 30.
