Four wires (29) which transmit the input / output signals from the servo system to each other and support the objective lens holder (28) to oscillate and attenuate the vibration during an impact from the outside. And a holder gel 30 fixed to the second yoke 23 to support the wire 29 and attached to an outer side of the holder gel 30 to receive an input / output signal of a servo system. The wire 31 is installed on both sides of the PCB 31 and the objective lens holder 26. 9) and a coil PCB 32 for electrically connecting the focusing adjustment coil 27 and the tracking adjustment coil 28 to each other.

또한, 본 발명에 따른 액츄에이터의 대물렌즈홀더(26)는 정사각형과 같은 형상을 가지며, 정사각형의 외측으로 대물렌즈(25)가 설치되는 구조를 갖는다. 즉, 대물렌즈홀더(26)의 무게중심에 상기 내측요오크(21)에 유동가능하게 끼워질 수 있도록 포커싱 조정코일(27) 및 트랙킹 조정코일(28)이 설치되어, 광픽업 액츄에이터의 구동시, 코일의 구동력 중심점과 대물렌즈 홀더(26)의 무게중심이 일치하며 이에 따라 대물렌즈홀더(26)의 내측에 장착된 하나의 포커싱 조정코일(27) 및 트랙킹 조정코일(28)에 상기 영구자석(24)의 로렌츠 구동력으로 대물렌즈홀더(26)가 충분하게 움직이게 되는 것이다. 그리고, 상기 대물렌즈 홀더(26)의 소정위치에는 구동시 무게중심을 보정하는 밸랜서(33)가 끼움결합될 수 있도록 도면에 미도시된 홈이 형성되어 있다.In addition, the objective lens holder 26 of the actuator according to the present invention has a shape such as a square, and has a structure in which the objective lens 25 is installed outside the square. That is, a focusing adjustment coil 27 and a tracking adjustment coil 28 are installed at the center of gravity of the objective lens holder 26 so as to be able to be inserted into the inner yoke 21 so that the optical pickup actuator is driven. The center of gravity of the driving force center point of the coil coincides with the center of gravity of the objective lens holder 26, and thus the permanent magnet is mounted on the focusing adjustment coil 27 and the tracking adjustment coil 28 mounted inside the objective lens holder 26. The objective lens holder 26 is sufficiently moved by the Lorentz driving force of (24). In addition, a groove, not shown in the drawing, is formed at a predetermined position of the objective lens holder 26 so that the balancer 33 for correcting the center of gravity when driving is fitted.

이와같이, 구성된 종래 광픽업 액츄에이터의 작용을 상세히 설명하면 다음과 같다.Thus, the operation of the conventional optical pickup actuator configured in detail as follows.

제1도 및 제2도에 도시된 바와같이, 광학계상의 광검출장치(Photo Detector)에서 레이져빔의 기록피트에서의 포커싱 및 트랙킹상태를 검출하게 된다. 여기서, 포커싱 및 트랙킹 상태를 검출한 결과 교정이 필요한 경우에는 서보시스템에서는 PCB(31)에 전기적인 신호를 전달한다. PCB(31)에서 와이어(29)를 통하여 코일 PCB(32)에 전달된 전기적인 신호에 의하여 대물렌즈홀더(26)내의 무게중심에 설치되어 있는 포커싱 조정코일(27) 및 트랙킹 조정코일(28)이 영구자석(24)과의 자속으로 인해서 로렌츠 구동력을 받게 된다.As shown in Figs. 1 and 2, the photo detector on the optical system detects the focusing and tracking states at the recording feet of the laser beam. In this case, when calibration is necessary as a result of detecting the focusing and tracking states, the servo system transmits an electrical signal to the PCB 31. Focusing adjustment coil 27 and tracking adjustment coil 28 installed at the center of gravity in the objective lens holder 26 by an electrical signal transmitted from the PCB 31 to the coil PCB 32 via the wire 29. The magnetic flux with the permanent magnet 24 receives the Lorentz driving force.

그리고, 포커싱 조정코일(27) 및 트랙킹 조정코일(28)에 와이어(29)를 통하여 전류가 인가되면 트랙킹 조정코일(27) 및 포커싱 조정코일(26)과 외측요오크(22)의 내면에 장착된 영구자석(24)간의 로렌츠 구동력이 발생하여 대물렌즈홀더(26)가 구동하게 된다. 이때 대물렌즈홀더(26)의 무게중심에 상기 포커싱 조정코일(27)이 유동되게 끼움 결합되는 내측 요오크(21)가 설치되어 대물렌즈홀더(26)의 구동시 코일의 구동력 중심점과 가동부인 대물렌즈 홀더(26)의 무게중심점이 일치하게 된다.Then, when a current is applied to the focusing adjustment coil 27 and the tracking adjustment coil 28 through the wire 29, the tracking adjustment coil 27 and the focusing adjustment coil 26 and the inner surface of the outer yoke 22 are mounted. The Lorentz driving force between the permanent magnets 24 is generated and the objective lens holder 26 is driven. At this time, the inner yoke 21 is installed in the center of gravity of the objective lens holder 26 so that the focusing adjustment coil 27 is flowed so that the center of the driving force and the moving part of the coil when the objective lens holder 26 is driven. The center of gravity of the lens holder 26 coincides.

이와같이, 상기와 반대로 와이어(29)를 통해서 포커싱조정코일(27) 및 트랙킹조정코일(28)에 전류가 인가되면 외측요오크(22) 내면에 각각 부착된 영구자석(24)간에 강력한 로렌츠 구동력이 발생하여 대물렌즈홀더(26)가 트랙킹방향과 포커싱 방향으로 동작하게 되는 것으로서, 이때 영구자석(24)에 강한 반발력이 가해지면서 영구자석(24)을 지지해주고 있는 외측 요오크(22)에도 강한 반발력이 가해지게 된다.As described above, when current is applied to the focusing adjustment coil 27 and the tracking adjustment coil 28 through the wire 29, a strong Lorentz driving force is applied between the permanent magnets 24 attached to the inner surface of the outer yoke 22, respectively. When the objective lens holder 26 is operated in the tracking direction and the focusing direction, a strong repulsive force is applied to the permanent magnet 24, and a strong repulsive force is also applied to the outer yoke 22 that supports the permanent magnet 24. Will be added.

한편, 상기 대물렌즈홀더(26)가 상,하,좌,우 방향으로 동작함에 따라 홀더겔(34)에 충진된 댐핑겔이 와이어(29)의 진동을 적절하게 흡수하여서 와이어(29)에서 정확한 동작성능이 나오도록 보조해주는 것이다.Meanwhile, as the objective lens holder 26 operates in the up, down, left, and right directions, the damping gel filled in the holder gel 34 appropriately absorbs the vibrations of the wire 29 so that the wire 29 is accurate. It is to help the operation performance.

그리고, 상기한 바와 같이 대물렌즈홀더(27)의 외주면에는 포커싱조정코일(27)이 수십내지 수백번의 횟수로 권선되어 있으며, 다시 그 포커싱 조정코일(27)의 외측면에는 두 개씩의 트랙킹조정코일(28)이 유브이 본드에 의해 접착되어져 있으며, 상기 트랙킹조정코일(28) 및 포커싱조정코일(27)은 서로 대물렌즈홀더(26)의 양측면에 접착된 코일 피씨비(32)에 서로 연결되어 전류가 도전되도록 구성되는 것이다.As described above, the focusing adjustment coil 27 is wound on the outer circumferential surface of the objective lens holder 27 several tens to hundreds of times, and again the tracking adjustment is performed on the outer surface of the focusing adjustment coil 27 by two. The coil 28 is bonded by a UV bond, and the tracking adjustment coil 28 and the focusing adjustment coil 27 are connected to each other by a coil PC 32 bonded to both sides of the objective lens holder 26 so that the current Is configured to be challenged.

그런데, 상기 트랙킹조정코일(28)과 포커싱조정코일(27)을 서로 연결 하는 것과 각각의 조정코일(27)(28)을 코일 피씨비(32)에 납땜 고정시키기 위해서는 작업자가 직접 대물렌즈홀더(26)를 일일이 들고 조립 작업을 수행하고, 계속해서 유브이 본드로 대물렌즈홀더(26) 주위에 부착된 조정코일(27)(28)과 코일 피씨비(32)에 코팅시키는 작업을 수행하는 것으로서 작업자가 대물렌즈홀더(26)를 잡고 조립작업을 수행하는 도중에 코일을 정확하고, 신속하게 처리하지 못하여 광픽업 액츄에이터의 조립성 및 생산성이 현저하게 떨어지는 문제점이 있었다.However, in order to connect the tracking adjustment coil 28 and the focusing adjustment coil 27 to each other and to fix and fix the respective adjustment coils 27 and 28 to the coil PC 32, the operator directly operates the objective lens holder 26. And carry out the assembly work, and then continue to coat the adjustment coils (27) and (28) and coil PC (32) attached around the objective lens holder (26) with a UV bond. While holding the lens holder 26 and performing the assembly operation, the coil could not be accurately and quickly processed, and thus there was a problem in that the assembly and productivity of the optical pickup actuator were remarkably degraded.

본 발명은 이러한 점을 감안하여 안출한 것으로, 대물렌즈홀더의 외주면에 설치되는 포커싱조정코일 및 트랙킹조정코일을 코일 피씨비에 선재 처리하기 좋도록 다수개의 대물렌즈홀더를 받침대상에 수평으로 연결되어 지지된 수평지지대에 안착시키고, 받침대에 대해 일정각도 회전하는 누름판으로 대물렌즈홀더의 상부면을 눌러 고정시킨 상태로 대물렌즈홀더 양측면에 조정코일의 선재를 처리하므로써 광픽업 액츄에이터의 조립성 및 생산성을 향상시키는 것이 목적이다.The present invention has been made in view of this point, and a plurality of objective lens holders are horizontally connected on a pedestal so that the focusing adjustment coils and tracking adjustment coils installed on the outer circumferential surfaces of the objective lens holders can be wired to the coil PC.

The purpose is to.

이러한 목적은 대물렌즈가 상부면에 안치되는 대물렌즈홀더와, 상기 대물렌즈홀더의 외주면에 감겨지거나 접착되어 코일 피씨비에 연결되며, 대물렌즈홀더를 포커싱 조정방향 및 트랙킹 조정방향으로 동작시키는 트랙킹 조정코일 및 포커싱조정코일을 구비한 광픽업 액츄에이터에 있어서, 상기 대물렌즈홀더가 다수개 수평으로 안착되어 대물렌즈홀더의 저면에 형성된 하부요홈이 끼워지는 받침돌기가 상부면에 형성된 받침부재와, 상기 받침부재의 양측 끝단부를 각각 지지해주고, 좌,우로 관통된 끼움공이 형성된 받침부재와, 상기 받침부재의 끼움공이 끼워지는 고정볼트에 의해 너트로 체결되어 수평지지부재상에 안치된 대물렌즈홀더의 상부면을 눌러 고정시키는 누름부재로 구성된 것을 특징으로 하는 선재 처리용 대물렌즈홀더 고정장치를 제공함으로써 달성된다.This purpose is to provide an objective lens holder in which an objective lens is placed on an upper surface and a coil wound around the outer peripheral surface of the objective lens holder and connected to a coil PC, and a tracking adjustment coil for operating the objective lens holder in a focusing adjustment direction and a tracking adjustment direction.
