Description

스핀들 모터 {SPINDLE MOTOR}Spindle Motors {SPINDLE MOTOR}

본 발명은 스핀들 모터에 관한 것이다.The present invention relates to a spindle motor.

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

도 1은 종래의 스핀들 모터의 사시도로서, 이를 설명한다.1 is a perspective view of a conventional spindle motor, which will be described.

도시된 바와 같이, 베이스(11)에 기판(21) 및 모터부(31)가 설치된다. 기판(21)에는 보조기판(25)이 일체로 형성되는데, 보조기판(25)은 기판(21)과 접속됨과 동시에 제품의 메인기판 또는 광픽업 이송용 스테핑 모터 등과 같은 상대물과 접속된다.As shown, the substrate 21 and the motor unit 31 are installed on the base 11. The auxiliary substrate 25 is integrally formed on the substrate 21. The auxiliary substrate 25 is connected to the substrate 21 and to a counterpart such as a main substrate of a product or a stepping motor for optical pickup transfer.

모터부(31)는 베이스(11)에 지지 설치되어 기판(21)과 접속하며, 외부의 전원이 기판(21)을 통하여 모터부(31)로 공급되면, 회전하면서 디스크를 회전시킨다.The motor part 31 is supported by the base 11 and is connected to the board | substrate 21, When an external power supply is supplied to the motor part 31 through the board | substrate 21, it rotates a disk while rotating.

상기와 같은 종래의 스핀들 모터는 기판(21)에 보조기판(25)이 일체로 형성되고, 기판(21)과 보조기판(25)의 크기와 대응되게 베이스(11)를 형성하여야 하므로, 원가가 상승하는 단점이 있다.In the conventional spindle motor as described above, since the auxiliary substrate 25 is integrally formed on the substrate 21 and the base 11 is formed to correspond to the size of the substrate 21 and the auxiliary substrate 25, the cost is low. There is a drawback to rising.

또한, 보조기판(25)과 상기 상대물과의 접속을 위하여 커넥터(27)를 각각 설치한다. 즉, FFC(29)의 일측 및 타측을 보조기판(25)의 커넥터(27) 및 상기 상대물의 커넥터에 각각 삽입 접속한다. 따라서, 보조기판(25)의 커넥터(27)와 상기 상대물의 커넥터가 필요하므로, 더욱 원가가 상승하는 단점이 있다.In addition, the connector 27 is provided for the connection between the auxiliary substrate 25 and the counterpart, respectively. That is, one side and the other side of the FFC 29 are inserted into and connected to the connector 27 of the auxiliary substrate 25 and the connector of the counterpart, respectively. Therefore, since the connector 27 of the auxiliary substrate 25 and the connector of the counterpart are required, the cost increases further.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 원가를 절감할 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 to provide a spindle motor that can reduce the cost.

상기 목적을 달성하기 위한 본 발명에 따른 스핀들 모터는, 베이스; 상기 베이스에 결합된 기판; 상기 베이스에 결합 설치되며 상기 기판과 접속된 모터부를 포함하며,Spindle motor according to the present invention for achieving the above object, the base; A substrate coupled to the base; A motor unit coupled to the base and connected to the substrate,

상기 기판은 상기 모터부를 구동하기 위한 회로로 구성되고, 상기 기판에는 FFC(Flexible Flat Cable)의 일측이 납땜 접속되며, 상기 FFC의 타측은 상대물과 납땜 접속된다.The substrate is composed of a circuit for driving the motor unit, one side of the FFC (Flexible Flat Cable) is soldered to the substrate, the other side of the FFC is soldered and connected to the counterpart.

본 발명에 따른 스핀들 모터는 모터부를 구동시키기 위한 기판만이 마련되고, 기판과 대략 비슷한 크기로 베이스가 형성된다. 그러므로, 원가가 절감된다.In the spindle motor according to the present invention, only a substrate for driving the motor unit is provided, and a base is formed to a size substantially similar to that of the substrate. Therefore, the cost is reduced.

또한, FFC(Flexible Flat Cable)를 기판 및 커넥터에 납땜하여 기판과 상대물을 접속하므로, 별도의 커넥터가 필요 없다. 따라서, 원가가 더욱 감소된다.In addition, since the FFC (Flexible Flat Cable) is soldered to the board and the connector to connect the board and the counterpart, a separate connector is not necessary. Therefore, the cost is further reduced.

또한, 외부로 노출되어 기판 및 상대물에 납땜되는 FFC의 단자가 보강필름에 의하여 지지되므로, 단자의 변형이 없다. 따라서, 단자를 기판 및 상대물에 정확하게 납땜 접속할 수 있다.In addition, since the terminals of the FFC exposed to the outside and soldered to the substrate and the counterpart are supported by the reinforcement film, there is no deformation of the terminals. Therefore, the terminal can be soldered correctly to the substrate and the counterpart.

이하, 첨부된 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 2는 본 발명의 일 실시예에 따른 스핀들 모터의 사시도이다.2 is a perspective view of a spindle motor according to an embodiment of the present invention.

도시된 바와 같이, 본 실시예에 따른 스핀들 모터는 베이스(110)와 기판(120)과 모터부(130)를 가진다.As shown, the spindle motor according to the present embodiment has a base 110, a substrate 120 and the motor unit 130.

이하, 구성요소들의 면 및 방향을 지칭함에 있어서, 베이스(110)의 수직방향 상측을 향하는 면 및 방향을 "상면 및 상측", 하측을 향하는 면 및 방향을 "하면 및 하측"이라 한다.Hereinafter, in referring to the plane and the direction of the components, the plane and the direction facing upward in the vertical direction of the base 110 is referred to as "upper and upper side", the plane and the direction facing downward is referred to as "lower and lower side".

베이스(110)는 금속으로 형성되며, 하면이 제품에 결합된다. 기판(120)은 하면이 베이스(110)의 상면에 결합되고, 모터부(130)는 베이스(110)에 결합되어 베이스(110)에 대하여 수직으로 설치된다.Base 110 is formed of a metal, the lower surface is bonded to the product. The lower surface of the substrate 120 is coupled to the upper surface of the base 110, and the motor unit 130 is coupled to the base 110 to be installed perpendicular to the base 110.

모터부(130)의 고정자(131)의 코일(131a)은 기판(120)에 접속되어 외부의 전원을 공급받는다. 코일(131a)에 전원이 공급되면, 고정자(131)와 회전자(133)의 작용에 의하여 회전자(133)가 회전하고, 이로인해 회전자(133)의 로터요크(133a)에 탑재된 디스크가 회전한다.The coil 131a of the stator 131 of the motor unit 130 is connected to the substrate 120 to receive external power. When power is supplied to the coil 131a, the rotor 133 rotates due to the action of the stator 131 and the rotor 133, which causes the disk mounted on the rotor yoke 133a of the rotor 133. Rotates.

본 실시예에 따른 스핀들 모터의 기판(120)에는 모터부(130)의 구동에 필요 한 회로만 형성되므로, 기판(120)을 상대물과 접속시키기 위한 매개체가 필요하다. 이때, 상기 상대물은 전원 또는 제품의 메인기판 또는 스테핑 모터 등과 같은 적어도 2개이다.Since only a circuit necessary for driving the motor unit 130 is formed on the substrate 120 of the spindle motor according to the present embodiment, a medium for connecting the substrate 120 to the counterpart is required. At this time, the counterpart is at least two such as a main board or a stepping motor of a power source or a product.

이를 위하여 기판(120)과 상기 상대물은 FFC(Flexible Flat Cable)(140)에 상호 접속된다. 즉, FFC(140)의 일측 및 타측은 기판(120)에 형성된 접속단자(121) 및 상기 상대물에 각각 납땜 접속된다.To this end, the substrate 120 and the counterpart are interconnected to a flexible flat cable (FFC) 140. That is, one side and the other side of the FFC 140 are soldered to the connection terminal 121 formed on the substrate 120 and the counterpart, respectively.

본 실시예에 따른 스핀들 모터는 모터부(130)의 구동에 필요한 기판(120)만 마련되므로, 베이스(110)의 크기도 대략 기판(120)의 크기와 비슷하게 형성된다. 따라서, 기판(120)의 크기 및 베이스(110)의 크기가 감소되므로, 원가가 절감된다.Since the spindle motor according to the present exemplary embodiment is provided with only the substrate 120 required for driving the motor unit 130, the size of the base 110 is also formed to be approximately the size of the substrate 120. Therefore, since the size of the substrate 120 and the size of the base 110 are reduced, cost is reduced.

FFC(140)는 절연피복(141)과 복수의 단자(143)를 가진다. 단자(143)는 중앙부측은 절연피복(141)에 감싸이고 양단부측은 절연피복(141)의 외측으로 노출된다. 절연피복(141)의 외측으로 노출된 단자(143)의 일단부측 및 타단부측이 기판(120)의 접속단자(121) 및 상기 상대물에 각각 납땜 접속된다.The FFC 140 has an insulation coating 141 and a plurality of terminals 143. The terminal 143 is surrounded by an insulating coating 141 at the center portion thereof, and both ends thereof are exposed to the outside of the insulating coating 141. One end side and the other end side of the terminal 143 exposed to the outside of the insulating coating 141 are soldered to the connection terminal 121 and the counterpart of the substrate 120, respectively.

단자(143)의 두께는 대단히 얇기 때문에 절연피복(141)의 외측으로 노출된 단자(143)의 부위는 쉽게 변형된다. 그리고, 단자(143)의 두께가 얇으므로 인하여, 변형된 단자(143)의 위치를 정위치로 보정하기가 대단히 어렵다. 이로인해, 변형된 단자(143)의 위치를 정위치로 보정하여 기판(120) 및 상기 상대물의 정해진 위치에 납땜하기가 대단히 어렵다.Since the thickness of the terminal 143 is very thin, the portion of the terminal 143 exposed to the outside of the insulating coating 141 is easily deformed. And, because the thickness of the terminal 143 is thin, it is very difficult to correct the position of the deformed terminal 143 to the correct position. As a result, it is very difficult to correct the position of the deformed terminal 143 to the correct position and solder it to the predetermined position of the substrate 120 and the counterpart.

단자(143) 변형의 문제는 단자(143)의 일단부측을 기판(120)에 납땜한 후, 상기 상대물과의 접속을 위하여 포장 운반하는 도중에 특히 심하다. 따라서, 상기 상대물과 접속되는 단자(143)의 타단부측은 거의 위치 변형이 발생한다.The problem of deformation of the terminal 143 is particularly acute during packaging and transporting one end side of the terminal 143 to the substrate 120 for connection with the counterpart. Therefore, the position deformation of the other end side of the terminal 143 connected with the counterpart almost occurs.

본 실시예에 따른 스핀들 모터의 FFC(140)에는 단자(143)의 변형을 방지하는 보강필름(145)이 형성된다.In the FFC 140 of the spindle motor according to the present embodiment, a reinforcement film 145 is formed to prevent deformation of the terminal 143.

즉, 단자(143)의 일단부 및 타단부는 보강필름(145a,145b)에 감싸여 각각 지지되고, 절연피복(141)과 보강필름(145a) 사이에 위치된 단자(143)의 일단부측 부위 및 절연피복(141)과 보강필름(145b) 사이에 위치된 단자(143)의 타단부측 부위가 각각 기판(120) 및 상기 상대물에 납땜 접속된다.That is, one end portion and the other end portion of the terminal 143 are wrapped in the reinforcement films 145a and 145b to be supported, respectively, and the one end side portion of the terminal 143 positioned between the insulating coating 141 and the reinforcement film 145a. And portions of the other end side of the terminal 143 positioned between the insulating coating 141 and the reinforcing film 145b are soldered to the substrate 120 and the counterpart, respectively.

따라서, 절연피복(141)의 외측으로 노출된 단자(143)의 부위는 변형이 없으므로, 단자(143)를 용이하게 기판(120) 및 상기 상대물에 납땜 접속할 수 있다.Therefore, since the portion of the terminal 143 exposed to the outside of the insulating coating 141 is not deformed, the terminal 143 can be easily soldered to the substrate 120 and the counterpart.

도 3은 도 2에 도시된 기판에 FFC가 납땜된 상태를 보인 사시도로서, 이를 설명한다.3 is a perspective view illustrating a state in which an FFC is soldered to the substrate illustrated in FIG. 2, and this will be described.

도시된 바와 같이, 보강필름(145a,145b)은 절연제인 PET(Polyethylene terephthalate)로 마련된다. 그리고, 절연피복(141)과 보강필름(145a) 사이의 단자(143)의 일단부측 부위를 기판(120)에 납땜한 후, 보강필름(145a)을 접어서 납땜된 단자(143)의 일단부측 부위를 덮는다. 그러면, 보강필름(145a)에 의하여 절연의 효과가 있으므로, 안전하다.As shown, the reinforcement films 145a and 145b are made of polyethylene terephthalate (PET) which is an insulating material. Then, after soldering the one end portion of the terminal 143 between the insulating coating 141 and the reinforcing film 145a to the substrate 120, the one end portion of the terminal 143 that is soldered by folding the reinforcing film 145a. To cover. Then, since the reinforcement film 145a has the effect of insulation, it is safe.

이는, 상기 상대물에 납땜되는 단자(143)의 타단부측 부위도 보강필름(145b)을 접어서 덮으면 절연된다.This is insulated when the other end side portion of the terminal 143 soldered to the counterpart is folded and covered with the reinforcing film 145b.

도 4는 도 2에 도시된 기판에 FFC가 납땜된 다른 상태를 보인 사시도로서, 이를 설명한다.FIG. 4 is a perspective view illustrating another state in which the FFC is soldered to the substrate illustrated in FIG. 2.

도시된 바와 같이, 절연피복(141)과 보강필름(145a) 사이의 단자(143)의 일단부측 부위를 기판(120)에 납땜한 후, 보강필름(145a)을 절단하여 제거할 수 도 있다.As shown, after the end portion of the terminal 143 between the insulating coating 141 and the reinforcing film 145a is soldered to the substrate 120, the reinforcing film 145a may be cut and removed.

상기 상대물에 단자(143)의 타단부측을 납땜한 후, 보강필름(145b)도 절단하여 제거할 수 있다.After soldering the other end side of the terminal 143 to the counterpart, the reinforcement film 145b may also be cut and removed.
