이하, 첨부한 도면을 참조하여 본 발명의 일 실시예에 따른 렌즈 구동용 모터를 상세히 설명한다.Hereinafter, a lens driving motor according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일 실시예에 따른 렌즈 구동용 모터의 단면도이다.2 is a cross-sectional view of a lens driving motor according to an embodiment of the present invention.

도시된 바와 같이, 상호 결합되어 내부에 소정 공간을 형성하는 베이스(110)와 하우징(120)이 마련된다. 하우징(120)은 하면이 개방되어 베이스(110)에 결합되고, 베이스(110)와 하우징(120)의 상면에는 후술할 캐리어(Carrier)(150)가 출입하 는 출입공(113,123)이 대응되게 형성된다.As shown, the base 110 and the housing 120 are coupled to each other to form a predetermined space therein. The lower surface of the housing 120 is coupled to the base 110, and the base 110 and the upper surface of the housing 120 correspond to the access holes 113 and 123 through which the carrier 150 to be described later enters. Is formed.

하우징(120)의 내부에는 링형상의 요크(130)가 고정되고, 요크(130)에는 링형상의 마그네트(140)가 고정된다. 그리고, 요크(130)의 내부에는 렌즈(200)가 설치된 캐리어(150)가 승강가능하게 설치되고, 캐리어(150)의 외주면에는 코일(160)이 고정되어 마그네트(140)와 대향한다. 그리하여, 코일(160)에 전류가 공급되면, 코일(160)과 마그네트(140) 사이에 형성되는 전자기력에 의하여 코일(160)이 상승하고, 이로인해 캐리어(150)가 상승하면서 렌즈(200)를 상승시킨다.A ring-shaped yoke 130 is fixed to the inside of the housing 120, and a ring-shaped magnet 140 is fixed to the yoke 130. In addition, the carrier 150 having the lens 200 installed therein is movable inside the yoke 130, and the coil 160 is fixed to the outer circumferential surface of the carrier 150 to face the magnet 140. Thus, when a current is supplied to the coil 160, the coil 160 is raised by the electromagnetic force formed between the coil 160 and the magnet 140, thereby raising the carrier 150 while lifting the lens 200 Raise.

베이스(110)와 요크(130)의 하면 사이 및 하우징(120)의 상면과 요크(120)의 상면 사이에는 탄성을 가진 스페이서(Spacer)(170)가 설치되는데, 스페이서(170)는 신축되면서 베이스(110)와 하우징(120)의 내부에 조립되는 부품들의 치수 공차 및 조립시 발생하는 조립 오차에 의한 공차를 보상해 준다.A spacer 170 having elasticity is installed between the base 110 and the lower surface of the yoke 130 and between the upper surface of the housing 120 and the upper surface of the yoke 120. Compensation for the tolerance due to the dimensional tolerances of the parts assembled in the interior of the 110 and the housing 120 and the assembly error occurs during assembly.

요크(130)의 상하측에는 링형상의 스프링(180)이 설치된다. 상세히 설명하면, 요크(130)의 상측에 설치된 스프링(180)은 외주면측이 하우징(120)과 스페이서(170) 사이에 삽입되어 지지되고, 내주면측이 캐리어(150)의 상면에 결합 고정된다. 그리고, 요크(130)의 하측에 설치된 스프링(180)은 외주면측이 베이스(110)와 스페이서(170) 사이에 삽입되어 지지되고, 내주면측이 캐리어(150)의 하면에 결합 고정된다. 그리하여, 전자기력에 의하여 상승된 캐리어(150)는, 코일(160)에 공급되는 전류가 차단되면, 스프링(180)에 의하여 최초의 상태로 복귀된다.Ring-shaped springs 180 are installed on the upper and lower sides of the yoke 130. In detail, the spring 180 installed on the upper side of the yoke 130 has an outer circumferential surface side inserted between the housing 120 and the spacer 170 to be supported, and an inner circumferential surface side is fixedly coupled to the upper surface of the carrier 150. In addition, the spring 180 provided below the yoke 130 has an outer circumferential surface side inserted between the base 110 and the spacer 170 to be supported, and an inner circumferential surface side is fixedly coupled to the lower surface of the carrier 150. Thus, the carrier 150 lifted by the electromagnetic force is returned to the original state by the spring 180 when the current supplied to the coil 160 is cut off.

본 실시예에 따른 렌즈 구동용 모터에는 캐리어(150)와 스프링(180)의 결합위치를 표시함과 동시에 캐리어(150)와 스프링(150)을 결합시키는 수단이 마련되는 데, 이를 도 2 및 도 3을 참조하여 설명한다. 도 3은 도 2에 도시된 스프링과 캐리어의 사시도이다.The lens driving motor according to the present embodiment is provided with a means for coupling the carrier 150 and the spring 150 at the same time as indicating the coupling position of the carrier 150 and the spring 180, which is shown in Figs. It demonstrates with reference to 3. 3 is a perspective view of the spring and the carrier shown in FIG.

도시된 바와 같이, 상기 수단은 스프링(180)의 내주면측에 형성된 결합공(183)과 캐리어(150)의 상면 및 하면에 각각 형성되어 결합공(183)에 삽입 돌출되는 돌기(153)로 마련된다. 즉, 돌기(153)에 결합공(183)을 삽입하여 스프링(180)을 캐리어(150)에 결합하면, 스프링(180)이 캐리어(150)의 정해진 부위에 결합되는 것이다.As shown, the means is provided with a coupling hole 183 formed on the inner circumferential surface side of the spring 180 and a protrusion 153 which is formed on the upper and lower surfaces of the carrier 150 and inserted into the coupling hole 183. do. That is, when the coupling hole 183 is inserted into the protrusion 153 to couple the spring 180 to the carrier 150, the spring 180 is coupled to a predetermined portion of the carrier 150.

스프링(180)이 캐리어(150)의 정해진 부위에 정확하게 결합되므로, 스프링(180)의 내부 응력 편차는 생기지 않는다. 그러므로, 캐리어(180) 및 렌즈(200)가 수평을 유지하면서 승강한다. 스프링(180)과 캐리어(150)의 견고한 결합을 위하여, 돌기(153)의 중앙부(153a)측은 열융착되어 스프링(180)에 고정된다.Since the spring 180 is precisely coupled to a predetermined portion of the carrier 150, there is no internal stress variation of the spring 180. Therefore, the carrier 180 and the lens 200 are raised and lowered while keeping the level. In order to firmly couple the spring 180 and the carrier 150, the central portion 153a side of the protrusion 153 is heat-sealed and fixed to the spring 180.

캐리어(150)에 렌즈(200)를 결합하기 위해서는 지그 등으로 캐리어(150)를 고정한 상태에서 렌즈(200)를 캐리어(150)에 결합하여야 한다. 이때, 상기 지그로 돌기(153)의 테두리부측 집어서 캐리어(150)를 고정한 후, 렌즈(200)를 결합하면 된다.In order to couple the lens 200 to the carrier 150, the lens 200 must be coupled to the carrier 150 while the carrier 150 is fixed by a jig or the like. In this case, the edge of the protrusion 153 is picked up by the jig to fix the carrier 150, and then the lens 200 may be coupled.

열융착되는 돌기(153)의 중앙부(153a)측은 돌기(153)와 일체로 형성되어 열융착될 수 있고, 돌기(153)와 별개로 형성되어 열융착될 수 도 있다.The central portion 153a side of the protrusion 153 that is thermally fused may be integrally formed with the protrusion 153 to be thermally fused, or may be formed separately from the protrusion 153 and thermally fused.

이상에서 설명한 바와 같이, 본 발명에 따른 렌즈 구동용 모터는 캐리어의 돌기에 스프링의 결합공을 삽입하여 돌기의 일측을 열융착하면, 스프링이 캐리어의 정해진 부위에 결합된다. 그러면, 스프링의 내부 응력 편차가 생기지 않으므로, 캐리어 및 캐리어에 결합된 렌즈가 수평을 유지하면서 승강한다. 따라서, 렌즈의 초점이 정확하게 맺히므로, 제품의 신뢰성이 향상된다.As described above, in the lens driving motor according to the present invention, when the coupling hole of the spring is inserted into the protrusion of the carrier to thermally fusion one side of the protrusion, the spring is coupled to the predetermined portion of the carrier. Then, since the internal stress deviation of the spring does not occur, the carrier and the lens coupled to the carrier are lifted while keeping the level. Therefore, since the focus of the lens is accurately formed, the reliability of the product is improved.

이상에서는, 본 발명의 일 실시예에 따라 본 발명을 설명하였지만, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 변경 및 변형한 것도 본 발명에 속함은 당연하다.In the above, the present invention has been described in accordance with one embodiment of the present invention, but those skilled in the art to which the present invention pertains have been changed and modified without departing from the spirit of the present invention. Of course.
