Description

멤즈 액츄에이터가 적용된 카메라모듈{Camera Module Having MEMS Actuator}Camera Module Having MEMS Actuator

본 발명은 MEMS 액츄에이터가 적용된 카메라모듈에 관한 것이다.The present invention relates to a camera module to which a MEMS actuator is applied.

각종 휴대단말기의 보급이 널리 일반화되고, 무선 인터넷 서비스가 상용화됨에 따라 휴대단말기와 관련된 소비자들의 요구도 다양화되고 있는바, 이에 따라 다양한 종류의 부가장치들이 휴대단말기에 장착되고 있다.As the spread of various portable terminals is widely used and the wireless Internet service is commercialized, the demands of consumers related to the portable terminals are diversified. Accordingly, various kinds of additional devices are installed in the portable terminals.

그 중에서 피사체를 사진이나 동영상으로 촬영하여 그 이미지데이터를 저장한 후 필요에 따라 이를 편집 및 전송할 수 있는 대표적인 것이 카메라 모듈이다.Among them, a camera module is one that can photograph a subject as a picture or a video, store the image data, and then edit and transmit the image data as necessary.

도1은 종래 VCM 액츄에이터가 적용된 카메라 모듈을 나타낸 사시도이다.1 is a perspective view showing a camera module to which a conventional VCM actuator is applied.

도1에 도시된 바와 같이 카메라모듈(10)은 일반적으로 전면에 렌즈(11a)가 구비되는 렌즈부(11)와, 상기 렌즈부(11)가 체결되는 VCM액츄에이터(12)와, IR필터(13)와, 이미지센서(14) 및, PCB(15)로 구성되어 피사체의 광이미지를 상기 렌즈부(11)가 수광받아 IR필터(13)로 전달하고, 상기 IR필터(13)는 수광된 광이미지에서 적외선을 차단한 후 이미지센서(14)로 조사하게 되며, 상기 이미지센서(14)는 조사된 광이미지를 전기적인 신호로 변환하여 상기 PCB(15)를 통해 출력되는 메카 니즘을 갖는다.As shown in FIG. 1, the camera module 10 generally includes a lens unit 11 having a lens 11a on the front surface, a VCM actuator 12 to which the lens unit 11 is fastened, and an IR filter. 13, the image sensor 14, and the PCB 15 are configured to receive an optical image of a subject by the lens unit 11 and receive the IR image 13 to the IR filter 13. The infrared ray is blocked from the optical image and then irradiated to the image sensor 14, and the image sensor 14 converts the irradiated optical image into an electrical signal and has a mechanism output through the PCB 15.

한편, 상기 렌즈부(11)는 이미지센서(14)와의 거리 조절을 통한 초기 포커싱을 셋팅할 수 있도록 상기 VCM액츄에이터(12)에 나사체결방식에 의해 체결 조립되는 구조를 갖게 되고, 이에 따라 상기 렌즈부(11)가 상기 VCM액츄에이터(12) 상에서 어느 한방향으로 회전됨에 따라 렌즈 초기 초점이 조정된다.On the other hand, the lens unit 11 has a structure that is fastened and assembled by the screwing method to the VCM actuator 12 to set the initial focusing by adjusting the distance with the image sensor 14, accordingly the lens The lens initial focus is adjusted as the unit 11 is rotated in either direction on the VCM actuator 12.

이때, 상기 VCM액츄에이터(12)와 상기 PCB(15)간에 전기적 신호를 주고 받을 수 있도록 상기 VCM액츄에이터(12)의 하부에는 단자부(12a)가 외부로 돌출되게 구비되는데, 상기 단자부(12a)는 상기 VCM액츄에이터(12)가 상기 PCB(15)와 조립되었을 때 PCB(15)와 전기적으로 연결된다.At this time, the lower portion of the VCM actuator 12 is provided so that the terminal portion 12a protrudes to the outside to transmit and receive electrical signals between the VCM actuator 12 and the PCB 15, the terminal portion 12a is When the VCM actuator 12 is assembled with the PCB 15, the VCM actuator 12 is electrically connected to the PCB 15.

참고로, VCM 액츄에이터가 적용된 카메라모듈은 코일을 감아서 제작되기 때문에 금속형 단자를 추출하는 것이 가능하다.For reference, since the camera module to which the VCM actuator is applied is manufactured by winding a coil, it is possible to extract a metal terminal.

그러나, 최근에는 도2에 나타낸 바와 같은 MEMS 액츄에이터가 적용된 카메라모듈(20)이 개발되었는바, 도2는 종래 MEMS 액츄에이터가 적용된 카메라모듈을 나타낸 사시도이다.However, recently, a camera module 20 to which a MEMS actuator is applied as shown in FIG. 2 has been developed. FIG. 2 is a perspective view showing a camera module to which a conventional MEMS actuator is applied.

참고로, MEMS(Micro-Electro Mechanical Ststem)기술이란, 마이크론 단위의 기계적 구조물과 전자회로가 집적화되어 결합된 시스템을 의미하는 것으로, 극히 미세한 실리콘 웨이퍼 구조물을 정밀하게 가공하고, 전자회로를 결합시킴으로써 렌즈의 초점거리를 조정하는 것을 말한다.For reference, MEMS (Micro-Electro Mechanical Ststem) technology refers to a system in which a micron unit mechanical structure and an electronic circuit are integrated and combined, and precisely process an extremely fine silicon wafer structure and combine the lens with an electronic circuit. To adjust the focal length.

여기서, 상기 MEMS 액츄에이터(21a)가 적용되면 실리콘 웨이퍼를 절단하여 사용하는 관계로 렌즈부(21)는 도시된 바와 같이 사각 형태를 이룰 수 밖에 없다.Here, when the MEMS actuator 21a is applied, the lens unit 21 has a rectangular shape as shown in the drawing, since the silicon wafer is cut and used.

그렇기 때문에, 상기 렌즈부(21)는 종래와 같이 카메라하우징(22)에 나사체결되어 직접 회전되는 방식으로 이미지센서와의 거리조정이 이루어지지 않고, 별개의 구성을 통해 비회전방식으로 상하 수직이동하게 된다.Therefore, the lens unit 21 is screwed to the camera housing 22 as in the related art, and thus does not adjust the distance with the image sensor in a manner of being directly rotated. Done.

또한, 상기 카메라하우징(22)의 하부에는 PCB(23)가 배치되는데, 여기서, 상기 렌즈부(21)에 있는 MEMS 액츄에이터(21a)와 상기 PCB(23)의 전기적 연결을 위해 상기 렌즈부(21)에는 도시된 바와 같이 패드단자(21b)가 구비된다.In addition, a PCB 23 is disposed below the camera housing 22, wherein the lens unit 21 is configured to electrically connect the MEMS actuator 21a in the lens unit 21 and the PCB 23. ) Is provided with a pad terminal 21b.

그러나, 도2에 도시된 바와 같은 종래 MEMS 액츄에이터가 적용된 카메라모듈에서의 패드단자(21b)는 앞에서 설명한 도1의 단자부와 달리 점접촉 형식의 패드로 이루어져 있기 때문에 단자부와 PCB를 연결하기가 매우 어려운 문제점이 있다.However, since the pad terminal 21b of the camera module to which the conventional MEMS actuator is applied as shown in FIG. 2 is made of a pad of a point contact type unlike the terminal portion of FIG. 1 described above, it is very difficult to connect the terminal portion and the PCB. There is a problem.

본 발명은 상술한 바와 같은 문제점을 해결하기 위한 것으로, 그 목적은 MEMS 액츄에이터가 적용된 카메라모듈에서 렌즈부의 단자와 PCB가 전기적으로 연결될 수 있도록 함에 있다.The present invention is to solve the above problems, the object is to enable the terminal of the lens unit and the PCB in the camera module to which the MEMS actuator is applied.

이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 보다 상세하게 설명한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도3은 본 발명에 따른 MEMS 액츄에이터가 적용된 카메라모듈을 나타낸 사시도이다.3 is a perspective view showing a camera module to which the MEMS actuator according to the present invention is applied.

도3을 참조하여 본 발명의 실시예를 설명하면, 본 발명은 크게 카메라하우징(110), 렌즈부(120), PCB부(130), 연성회로부(140)를 포함하여 이루어진다.Referring to FIG. 3, an embodiment of the present invention is largely comprised of a camera housing 110, a lens unit 120, a PCB unit 130, and a flexible circuit unit 140.

상기 카메라하우징(110)은 홀더라고 부르기도 하는데, 상기 카메라하우징(110)의 상부에는 상기 렌즈부(120)가 상하이동 가능하도록 설치되고, 상기 카메라하우징(110)의 하부에는 상기 PCB부(130)가 설치되어, 상기 렌즈부(120)의 신호가 상기 PCB부(130)로 전달되도록 한다.The camera housing 110 may be referred to as a holder, and the lens unit 120 is installed at the upper portion of the camera housing 110 so as to be movable. The PCB unit 130 is disposed below the camera housing 110. ) Is installed, so that the signal of the lens unit 120 is transmitted to the PCB unit 130.

즉, 상기 렌즈부(120)에는 피사체의 광이미지를 수광받기 위한 렌즈(121)가 구비되고, 그 광이미지는 전기적 신호로 변환되어 상기 PCB부(130)를 통해 출력된다.That is, the lens unit 120 includes a lens 121 for receiving an optical image of the subject, and the optical image is converted into an electrical signal and output through the PCB unit 130.

이때, 상기 렌즈부(120)는 렌즈초점의 조정을 위해서 상기 카메라하우징(110) 상에서 상하로 이동 가능하게 설치된다.In this case, the lens unit 120 is installed to be moved up and down on the camera housing 110 to adjust the lens focus.

그리고, 상기 렌즈부(120)에는 도시된 바와 같이 MEMS 액츄에이터(122)가 구비되는데, 상기 MEMS 액츄에이터(122)의 특성상 신호 전달을 위한 단자가 패드형태로 이루어지기 때문에 상기 렌즈부(120)의 일측에는 상기 MEMS 액츄에이터(122)의 신호를 전달하기 위한 패드단자(도2 참조)가 형성된다.In addition, the lens unit 120 is provided with a MEMS actuator 122 as shown, because the terminal for signal transmission due to the characteristics of the MEMS actuator 122 is made in the form of a pad, one side of the lens unit 120 A pad terminal (see FIG. 2) is formed in the MEMS actuator 122 to transmit a signal.

한편, 상기 PCB부(130)는 상기 카메라하우징(110)의 하부에 배치되는데, 상기 PCB부(130)가 광이미지를 전기적 신호로 전달받기 위해서는 상기 패드단자와의 전기적 연결이 이루어져야 한다.On the other hand, the PCB 130 is disposed below the camera housing 110, the PCB 130 must be electrically connected to the pad terminal in order to receive the optical image as an electrical signal.

그러나, 상술한 바와 같은 패드단자는 종래기술에서 설명한 바와 같이 그 크 기가 작고 강도가 약해 통상적인 와이어를 통한 전기연결을 수행하면 상기 패드단자가 손상될 우려가 있다.However, as described above, the pad terminal is small in size and weak in strength as described in the prior art, so that the pad terminal may be damaged when electrical connection is performed through a conventional wire.

따라서, 상기 연성회로부(140)를 통해 상기 패드단자와 상기 PCB부(130)가 전기적으로 연결되도록 하는 것이 바람직하다.Therefore, the pad terminal and the PCB 130 may be electrically connected through the flexible circuit unit 140.

상기 연성회로부(140)는 상기 렌즈부(120)의 전기적 신호를 상기 PCB부(130)로 전달할 수 있으면서 그 자체적 성질이 잘 구부러지고 휘어지는 인쇄회로기판(PCB)으로 이루어져 있어서, 상기 렌즈부(120)의 이동이나 변화에 용이하게 대응할 수 있는 장점이 있다.The flexible circuit unit 140 is formed of a printed circuit board (PCB) that is capable of transmitting electrical signals from the lens unit 120 to the PCB unit 130 and having its own property well bent and bent. There is an advantage that can easily cope with the movement or change of).

이와 같이 연하고 부드러운 성질을 갖는 연성회로부(140)를 상기 패드단자와 연결하면 그 두 물질의 성질이 비슷해 종래의 와이어 전기연결과 같이 금속을 연결할 때에 비해 상기 패드단자의 손상이 거의 없다.When the flexible circuit unit 140 having the soft and soft properties as described above is connected to the pad terminals, the properties of the two materials are similar, so that the pad terminals are hardly damaged as compared to the connection of metals as in the conventional wire electrical connection.

여기서, 상기 연성회로부(140)는 상기 패드단자에 접속될 때 전도성 양면테잎을 통해 연결되는 것이 바람직하다. 상기 패드단자는 앞에서 설명한 바와 같이 강도가 약하고 크기가 작기 때문에 연성회로부(140)와 패드단자를 서로 접속시키는 것이 매우 어려운 바, 이에 따라 전기전도가 이루어지는 전도성테잎을 통해 상기 연성회로부(140)와 패드단자를 접속시키면 손쉽게 두 부재를 전기적으로 연결할 수 있게 된다.Here, the flexible circuit unit 140 is preferably connected via a conductive double-sided tape when connected to the pad terminal. Since the pad terminal is weak in strength and small in size as described above, it is very difficult to connect the flexible circuit unit 140 and the pad terminal to each other. Accordingly, the flexible circuit unit 140 and the pad are formed through a conductive tape. Connecting the terminals makes it easy to electrically connect the two members.

한편, 상기 렌즈부(120)가 움직이게 되면 상기 패드단자에 결합된 상기 연성회로부(140)의 결합력이 크지 않기 때문에 상기 연성회로부(140)가 상기 패드단자 로부터 이탈될 우려가 있다.On the other hand, when the lens unit 120 is moved, the coupling force of the flexible circuit unit 140 coupled to the pad terminal is not large, so the flexible circuit unit 140 may be separated from the pad terminal.

상기 연성회로부(140)가 상기 패드단자로부터 이탈되는 것을 방지하기 위해서 상기 연성회로부(140)는 주위 구조물에 고정되는 것이 바람직한 바, 상기 연성회로부(140)는 실리콘이나 에폭시에 의해 상기 카메라하우징(110)이나 상기 렌즈부(120)나 상기 PCB부(130) 중 적어도 어느 하나에 고정되는 것이 좋다.In order to prevent the flexible circuit unit 140 from being separated from the pad terminal, the flexible circuit unit 140 is preferably fixed to the surrounding structure, and the flexible circuit unit 140 is formed of silicon or epoxy in the camera housing 110. ) Or at least one of the lens unit 120 or the PCB unit 130.

이상, 본 발명을 바람직한 실시예를 사용하여 상세히 설명하였으나, 본 발명의 범위는 설명된 특정 실시예에 한정되는 것은 아니며, 당해 기술 분야에서 통상의 지식을 가진 자라면 본 발명의 범위 내에서 얼마든지 구성요소의 치환과 변형이 가능한바, 이 또한 본 발명의 권리에 속하게 된다.As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to the specific Example described, and the person of ordinary skill in the art is not limited within the scope of this invention. Substitution and modification of the components are possible, which also belongs to the rights of the present invention.
