본 발명은 엔코더의 설치구조를 개선한 스핀들 모터에 관한 것이다.The present invention relates to a spindle motor having an improved installation structure of an encoder.

스핀들 모터는 ODD(Opticla Disk Drive)의 내부에 설치되어, 직선운동하는 광 픽업이 디스크에 기록된 데이타를 읽을 수 있도록 디스크를 회전시키는 기능을 한다.The spindle motor is installed in the ODD (Opticla Disk Drive) to rotate the disk so that the linear pickup can read the data recorded on the disk.

ODD의 기술 진보에 따라, CD(Compact Disk) 또는 DVD(Digiatl Versatile Disk)의 표면에 원하는 디자인을 레이저로 인쇄하는 라이트 스크라이브(Light Scribe) 기능이 부가된 ODD가 개발되어 사용되고 있다. 그런데, 디스크에 기록된 정보를 재생하거나 디스크에 정보를 기록하기 위해서는 디스크를 약 5,400rpm 정도의 고속으로 회전시켜야 하고, 디스크의 표면에 디자인을 인쇄하기 위해서는 디스크를 40rpm정도의 저속으로 회전시켜야 한다.According to ODD technology advancement, ODDs with a light scribing function of laser printing a desired design on a surface of a compact disk (CD) or a DVD (Digiatl Versatile Disk) have been developed and used. However, in order to reproduce the information recorded on the disc or record the information on the disc, the disc should be rotated at a high speed of about 5,400 rpm, and in order to print a design on the surface of the disc, the disc should be rotated at a low speed of 40 rpm.

이를 위하여, 스핀들 모터에는 디스크의 표면에 디자인을 인쇄할 때, 디스크가 적정한 회전속도로 회전되는지를 감지하는 엔코더(Encoder)가 설치된다.To this end, the spindle motor is provided with an encoder which detects whether the disk is rotating at an appropriate rotational speed when printing the design on the surface of the disk.

도 1 내지 도 2b를 참조하여 종래의 엔코더 설치구조를 설명한다. 도 1은 종래의 스핀들 모터의 구성을 보인 단면도이고, 도 2a는 도 1의 "A" 부 확대도이며, 도 2b는 도 2a에 도시된 엔코더의 평면도이다.A conventional encoder mounting structure will be described with reference to FIGS. 1 to 2B. 1 is a cross-sectional view showing a configuration of a conventional spindle motor, FIG. 2A is an enlarged view "A" of FIG. 1, and FIG. 2B is a plan view of the encoder shown in FIG. 2A.

도시된 바와 같이, 디스크(50)의 표면에 디자인을 인쇄하기 위해서는 라벨 등이 부착되는 디스크(50)의 상면이 하측을 향하도록 디스크(50)를 턴테이블(11)에 탑재한다.As shown, in order to print a design on the surface of the disk 50, the disk 50 is mounted on the turntable 11 so that the upper surface of the disk 50 to which a label or the like is attached faces downward.

이때, 디자인이 인쇄되는 디스크(50)의 상면 부위 중, 턴테이블(11) 외측에 위치된 디스크(50)의 부위에는 테형태의 인식마크(53)가 형성되고, 인식마크(53) 하측의 메인 PCB(13)에는 엔코더(Encoder)(21)가 설치된다. 그리하여, 엔코더(21)가 인식마크(53)를 감지하여 디스크(50)가 적정한 속도로 회전되는가를 감지한다.At this time, among the upper portions of the upper surface of the disk 50 on which the design is printed, the portion of the disk 50 positioned outside the turntable 11 is formed with a recognition mark 53 having a rim shape, and the main mark under the recognition mark 53 is formed. On the PCB 13, an encoder 21 is installed. Thus, the encoder 21 detects the recognition mark 53 to detect whether the disk 50 is rotated at an appropriate speed.

엔코더(21)는 정해진 소형으로 제조되므로, 엔코더(21)와 디스크(50) 사이의 간격을 설정 범위 이내로 하기 위해서는, 엔코더(21)의 하측에 별도의 지지부재를 설치하여야 한다.Since the encoder 21 is manufactured in a small size, in order to keep the gap between the encoder 21 and the disk 50 within a setting range, a separate supporting member must be provided below the encoder 21.

이를 위하여, 종래의 스핀들 모터는, 홀더(23)와 보조 PCB(25)를 적층한 다음, 단자(27)를 홀더(23)와 보조 PCB(25)에 관통시켜 홀더(23)와 보조 PCB(25)를 일체로 결합한다. 그리고, 단자(27)의 하단부 및 상단부를 메인 PCB(13) 및 보조 PCB(25)에 각각 납땜하고, 엔코더(21)를 보조 PCB(25)에 납땜한다.To this end, in the conventional spindle motor, the holder 23 and the auxiliary PCB 25 are stacked, and then the terminal 27 is penetrated through the holder 23 and the auxiliary PCB 25 so that the holder 23 and the auxiliary PCB ( 25) integrally combined. Then, the lower end and the upper end of the terminal 27 are soldered to the main PCB 13 and the auxiliary PCB 25, respectively, and the encoder 21 is soldered to the auxiliary PCB 25.

그러므로, 상기와 같은 종래의 스핀들 모터는 엔코더(21)를 설치하기 위하여, 홀더(23) 및 단자(27) 등이 필요하므로 부품 수가 증가하여 원가가 상승하는 단점이 있다.Therefore, the conventional spindle motor as described above requires the holder 23 and the terminal 27 to install the encoder 21, so that the number of parts increases and the cost increases.

또한, 홀더(23)와 보조 PCB(25)를 단자(27)를 이용하여 결합하여야 하고, 단자(27)를 메인 PCB(13) 및 보조 PCB(25)에 각각 납땜하여야 하므로 결합 공정이 복잡하여 더욱 원가가 상승하는 단점이 있다.In addition, the holder 23 and the auxiliary PCB 25 should be coupled using the terminal 27, and the terminal 27 should be soldered to the main PCB 13 and the auxiliary PCB 25, respectively, so that the coupling process is complicated. There is a further disadvantage that the cost rises.

또한, 많은 부품을 이용하여 엔코더(21)를 결합하므로, 결합 공정 도중의 공차로 인하여, 결합 정밀도가 저하되는 단점이 있다.In addition, since the encoder 21 is coupled using many parts, there is a disadvantage in that the coupling accuracy is lowered due to the tolerance during the coupling process.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 원가를 절감함과 동시에 결합 정밀도를 향상시킬 수 있는 스핀들 모터를 제공함에 있다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a spindle motor that can reduce the cost and at the same time improve the coupling accuracy.

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

도 3은 본 발명의 일 실시예에 따른 스핀들 모터의 구성을 보인 단면도이다.3 is a cross-sectional view showing the configuration of a spindle motor according to an embodiment of the present invention.

도시된 바와 같이, 베이스(110)가 마련된다. 베이스(110)의 상면에는 메인 PCB(120)(Printed Circuit Board)가 마련되고, 메인 PCB(120)를 관통한 베어링하우징(130)이 기립 설치된다.As shown, the base 110 is provided. A main PCB 120 (Printed Circuit Board) is provided on the upper surface of the base 110, and a bearing housing 130 penetrating the main PCB 120 is standing up.

베어링하우징(130)의 내부에는 베어링(135)이 압입되고, 베어링(135)에는 회전축(140)의 하부측이 지지되어 회전가능하게 설치된다. 베어링하우징(130)의 외주면에는 코어(151)와 코어(151)에 권선된 코일(155)을 가지는 고정자(150)가 고정되고, 베어링하우징(130)의 상측으로 노출된 회전축(140)의 외주면에는 부쉬(Bush)(160)가 결합된다.The bearing 135 is press-fitted into the bearing housing 130, and the bearing 135 is rotatably installed by supporting a lower side of the rotating shaft 140. A stator 150 having a core 151 and a coil 155 wound around the core 151 is fixed to an outer circumferential surface of the bearing housing 130, and an outer circumferential surface of the rotating shaft 140 exposed to the upper side of the bearing housing 130. Bush 160 is coupled to.

부쉬(160)의 외주면에는 디스크(50)가 탑재되는 턴테이블(170)이 결합되고, 턴테이블(170)의 저면에는 로터요크(181)와 마그네트(185)를 가지는 회전자(180)가 결합된다. 로터요크(181)는 하부 및 상부 중앙부측이 개방된 원통형상으로 마련되어, 상면은 턴테이블(170)의 저면에 결합되고 측면은 고정자(150)를 감싼다. 마그네트(185)는 로터요크(181)의 측면 내주면에 고정된다.The turntable 170 on which the disk 50 is mounted is coupled to the outer circumferential surface of the bush 160, and the rotor 180 having the rotor yoke 181 and the magnet 185 is coupled to the bottom of the turntable 170. The rotor yoke 181 is provided in a cylindrical shape with the lower and upper central portions open, the upper surface is coupled to the bottom surface of the turntable 170 and the side surrounds the stator 150. The magnet 185 is fixed to the side inner circumferential surface of the rotor yoke 181.

그리하여, 코일(155)에 전류가 인가되면, 코일(155)에서 발생하는 전기장과 마그네트(185)에서 발생하는 자기장과의 작용에 의하여 회전자(180)가 회전하고, 이로인해 턴테이블(170), 부쉬(160) 및 회전축(140)이 회전하는 것이다.Thus, when a current is applied to the coil 155, the rotor 180 is rotated by the action of the electric field generated in the coil 155 and the magnetic field generated in the magnet 185, thereby causing the turntable 170, Bush 160 and the rotating shaft 140 is to rotate.

그리고, 부쉬(160)에는 턴테이블(170)의 상면에 탑재된 디스크(50)의 중심이 회전축(120)의 중심과 일치하도록 디스크(50)를 탄성 지지하는 클램프(190)가 설치된다.The bush 160 is provided with a clamp 190 for elastically supporting the disk 50 so that the center of the disk 50 mounted on the upper surface of the turntable 170 coincides with the center of the rotation shaft 120.

메인 PCB(120)에는 엔코더(Encoder)(210)가 설치되고, 엔코더(210)는 디스크(50)의 회전속도를 감지한다. 상세히 설명하면, 라이트 스크라이브(Light Scribe) 기능을 구비하는 ODD(Opticla Disk Drive)를 이용하여 디스크(50)의 표면에 디자인을 레이저로 인쇄하기 위해서는 디스크(50)가 40rpm 정도의 저속으로 회전되어야 한다. 이를 위하여, 디스크(50)의 표면에는 테형상의 인식마크(53)가 형성되고, 엔코더(210)는 인식마크(53)를 감지하여 디스크(50)의 회전속도를 감지한다.An encoder 210 is installed in the main PCB 120, and the encoder 210 detects a rotation speed of the disk 50. In detail, in order to laser-print a design on the surface of the disk 50 using an optical disk drive (ODD) having a light scribing function, the disk 50 must be rotated at a low speed of about 40 rpm. . To this end, a te-shaped recognition mark 53 is formed on the surface of the disc 50, and the encoder 210 detects the recognition mark 53 to detect the rotational speed of the disc 50.

엔코더(210)는 정해진 소형으로 제조되므로, 엔코더(210)와 디스크(50) 사이의 간격을 설정 범위 이내로 하기 위해서는, 메인 PCB(120)의 상면에서 소정 높이에 엔코더(210)를 설치하여야 한다.Since the encoder 210 is manufactured in a small size, in order to keep the distance between the encoder 210 and the disk 50 within a setting range, the encoder 210 should be installed at a predetermined height on the upper surface of the main PCB 120.

본 실시예에 따른 스핀들 모터는 엔코더(210)를 메인 PCB(120)의 소정 높이 에 간단하게 설치하여 원가절감 및 결합 정밀도를 높일 수 있도록 마련되는데, 이를 도 4a 및 도 4b를 참조하여 설명한다. 도 4a는 도 3의 "B"부 확대도이고, 도 4b는 도 4a에 도시된 엔코더의 평면도이다.The spindle motor according to the present embodiment is provided to simply install the encoder 210 at a predetermined height of the main PCB 120 to increase the cost reduction and the coupling precision, which will be described with reference to FIGS. 4A and 4B. 4A is an enlarged view of a portion “B” of FIG. 3, and FIG. 4B is a plan view of the encoder shown in FIG. 4A.

도시된 바와 같이, 인식마크(53) 바로 하측의 메인 PCB(120)에는 소정 높이를 가지는 양면 PCB(220)가 납땜되어 접속되고, 양면 PCB(220)의 상면에는 엔코더(210)가 납땜되어 접속된다. 이때, 양면 PCB(220)는 에폭시(Epoxy)제로 마련되는 것이 바람직하다.As shown, the double-sided PCB 220 having a predetermined height is soldered and connected to the main PCB 120 directly below the recognition mark 53, and the encoder 210 is soldered and connected to the upper surface of the double-sided PCB 220. do. At this time, the double-sided PCB 220 is preferably made of epoxy (Epoxy).

그러면, 양면 PCB(220)를 메인 PCB(120)에 납땜하고, 양면 PCB(220)의 상면에 엔코더(210)를 납땜하면, 엔코더(210)와 디스크(50) 사이의 간격이 설정 범위 이내가 되므로, 간단하다.Then, when the double-sided PCB 220 is soldered to the main PCB 120, and the encoder 210 is soldered to the upper surface of the double-sided PCB 220, the distance between the encoder 210 and the disk 50 is within the setting range. It's simple.

이상에서 설명한 바와 같이, 본 발명에 따른 스핀들 모터는 메인 PCB에 양면 PCB의 저면을 납땜하고, 양면 PCB의 상면에 엔코더를 납땜하면, 엔코더가 설정된 높이에 설치된다. 그러므로, 엔코더를 메인 PCB에 결합하기 위한 부품 수가 줄어들고, 결합공정이 간단하므로 원가가 절감된다.As described above, when the spindle motor according to the present invention solders the bottom of the double-sided PCB to the main PCB, and the encoder is soldered to the upper surface of the double-sided PCB, the encoder is installed at a set height. Therefore, the number of components for coupling the encoder to the main PCB is reduced and the cost is reduced because the coupling process is simple.

또한, 부품수의 감소로 인해 결합공정이 줄어들므로, 결합공차가 줄어들어 결합정밀도가 향상된다.In addition, the coupling process is reduced due to the reduction in the number of parts, the coupling tolerance is reduced to improve the coupling precision.

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.
