The objective lens holder pressing member 46 for preventing the objective lens holder 34 to be lifted up when soldering the end of the suspension wire 36 is formed.
이와 같이 고정지그(38)는 상면 소정위치에 일정한 높이를 가지며 길이방향 양단에 대물렌즈 홀더(34)상의 코일장착부(34a)의 폭과 동일한 길이의 위치결정리브(48)가 돌설된 대물렌즈 홀더장착판(50)이 일체로 형성되고, 그 대물렌즈 홀더장착판(50)의 상면 중심으로부터는 베이스플레이트(32)상에 형성된 레이저빔 통과공(40)의 아랫쪽으로부터 끼워져 베이스플레이트(32)와 대물렌즈 홀더(34)의 유동을 방지하는 소정 높이의 유동방지보스(52)가 돌설된 메인플레이트(54)와, 상기 메인플레이트(54)의 양측단으로부터 상방향으로 일정 높이만큼 절곡되며, 전면에는 서스펜션 와이어(36)의 설치위치에 맞추어 4개의 서스펜션 와이어 끼움공(56, 56')이 형성된 한쌍의 서스펜션 지지플레이트(58)(58')로 이루어진다.As described above, the fixing jig 38 has a constant height at a predetermined position on the upper surface, and an objective lens holder protruding positioning ribs 48 having the same length as the width of the coil mounting portion 34a on the objective lens holder 34 at both ends in the longitudinal direction. The mounting plate 50 is integrally formed, and is fitted from the bottom of the laser beam passage hole 40 formed on the base plate 32 from the center of the upper surface of the objective lens holder mounting plate 50. The main plate 54 protruding from the flow preventing boss 52 of a predetermined height to prevent the flow of the objective lens holder 34, and is bent upward by a predetermined height from both side ends of the main plate 54, the front It consists of a pair of suspension support plates 58, 58 'formed with four suspension wire fitting holes 56, 56' in accordance with the installation position of the suspension wire 36.
그리고 대물렌즈 홀더누름부재(46)는 일정한 크기를 갖는 육면체형 플레이트(60)의 일측의 일정부분을 하향절곡하여 일측 서스펜션 와이어 지지플레이트(58)의 상면에 스크류(62)로써 고정결합하고, 타측의 일정 길이만큼을 양쪽으로 분리시켜 그 단부를 아랫쪽으로 만곡지게 절곡형성하여 대물렌즈 홀더(34)의 상면양측을 탄성적으로 눌러줄 수 있도록 하였다.The objective lens holder pressing member 46 is bent downward by a predetermined portion of one side of the hexahedral plate 60 having a predetermined size and fixedly coupled to the upper surface of the one side suspension wire support plate 58 with a screw 62. By separating a predetermined length of the two sides to bend to form the end bent downward so as to be able to elastically press both sides of the upper surface of the objective lens holder (34).
이와 같이 구성된 종래의 광픽업 액츄에이터 고정조립장치의 조립과정을 간단히 살펴보면, 고정지그(38)를 구성하는 메인 플레이트(54)의 상면에 형성된 대물렌즈 홀더장착판(50) 상의 유동방지보스(52)가 베이스플레이트(32)상의 레이저빔 통과공(40)에 하부로부터 끼워짐과 동시에 그 메인플레이트(54)의 양측단으로부터 상방향으로 절곡형성되는 한쌍의 서스펜션 와이어 지지플레이트(58, 58') 사이에는 베이스플레이트(32)상의 양측 외측요오크(42')가 접촉되어 내외측요오크(42, 42')를 포함하는 베이트플레이트(32) 전체의 전후 및 좌우방향 유동이 방지된다.Looking at the assembly process of the conventional optical pickup actuator fixed assembly device configured as described above, the flow preventing boss 52 on the objective lens holder mounting plate 50 formed on the upper surface of the main plate 54 constituting the fixing jig 38 Between the pair of suspension wire support plates 58 and 58 ', which is inserted from the bottom into the laser beam passing hole 40 on the base plate 32 and bent upward from both ends of the main plate 54. Both side outer yokes 42 'on the base plate 32 are in contact with each other to prevent the front, rear, and left and right flow of the bait plate 32 including the inner and outer yokes 42 and 42'.
이와 같은 상태에서 상면에 대물렌즈(78)가 장차된 대물렌즈 홀더(34)가 베이트플레이트(32)상의 각 내측요오크(42) 사이에 끼우면, 대물렌즈 홀더누름부재(46)를 일측 서스펜션 와이어 지지플레이트(58)의 상면에 스크류(80)로 고정하여 대물렌즈 홀더(34)의 상면이 탄성적으로 눌려지도록 함으로써, 대물렌즈 홀더(34) 및 베이트플레이트(32)가 유동되는 것을 방지하였다.In this state, when the objective lens holder 34 having the objective lens 78 on the upper surface is sandwiched between the respective inner yokes 42 on the bait plate 32, the objective lens holder pressing member 46 is attached to one side of the suspension wire. The upper surface of the objective lens holder 34 is elastically pressed by fixing the screw 80 on the upper surface of the support plate 58, thereby preventing the objective lens holder 34 and the bait plate 32 from flowing.
이와 같이 대물렌즈 홀더(34)가 고정된 상태에서 4개의 서스펜션 와이어(36)을 각각 대물렌즈 홀더(34)의 측면에 형성된 코일 끼움공(34b)에 끼운 후 납땜시키기 위하여 서스펜션 와이어(36)를 고정지그(38)의 서스펜션 와이어 지지플레이트(58, 58')에 각각 4개씩 형성된 서스펜션 와이어 끼움공(56, 56')에 끼우면서 서스펜션 와이어(36)가 대물렌즈 홀더(34)의 코일 끼움공(34b)에 끼워지도록 한다.As such, the suspension wires 36 are inserted in order to solder the four suspension wires 36 to the coil fitting holes 34b formed on the side surfaces of the objective lens holder 34 while the objective lens holder 34 is fixed. The suspension wire 36 is inserted into the coil fitting hole of the objective lens holder 34 while being inserted into the suspension wire fitting holes 56 and 56 ', each of which is formed on the suspension wire supporting plates 58 and 58' of the fixing jig 38, respectively. (34b).
이러한 상태에서 대물렌즈 홀더(34)의 코일 끼움공(34b)에 끼워진 서스펜션 와이어(36)을 납땜 시킨 후, 니퍼(nipper)와 같은 절단공구를 사용하여서 서스펜션 와이어(36)의 불필요한 8곳을 절단하여 조립을 완료 시켰다.In this state, after soldering the suspension wire 36 inserted into the coil fitting hole 34b of the objective lens holder 34, eight unnecessary portions of the suspension wire 36 are cut by using a cutting tool such as a nipper. To complete the assembly.
그런데, 상기한 바와 같이 절단공구를 사용하여 서스펜션 와이어(36)를 절단하는 작업은 모두 수작업으로 이루어지므로 조립작업이 복잡해질 뿐만아니라, 절단된 후 버려지는 서스펜션 와이어의 손실이 커지는 문제점이 있었다.By the way, as described above, the cutting work using the cutting tool to cut the suspension wire 36 is all made by hand, not only complicated assembling work, but also has a problem that the loss of the suspension wire is discarded after cutting.
또한, 서스펜션 와이어(36)를 서스펜션 와이어 끼움공(56, 56')과 대물렌즈 홀더(34)의 코일 끼움공(34b)에 각각 정확하게 끼우지 않을 경우 서스펜션 와이어(36)가 휘어질 뿐만 아니라, 서스펜션 와이어(36)의 절단위치가 정확하지 않게 되면 광픽업 액츄에이터에 롤링모드의 부공진에 의한 불량이 발생되는 문제점이 있었다.In addition, when the suspension wire 36 is not correctly inserted into the suspension wire fitting holes 56 and 56 'and the coil fitting hole 34b of the objective lens holder 34, the suspension wire 36 is not only bent, but also the suspension wire 36 If the cutting position of the wire 36 is not correct, there is a problem that a defect due to the negative resonance of the rolling mode occurs in the optical pickup actuator.

Passed through the soldering portion 83 of the bonded coil PCB 80 is entered into the coil fitting hole 82 of the coil fitting protrusion 81 is fitted.
이때, 서스펜션 와이어(36)가 약간 기울어지게 진입하여 서스펜션 와이어(36)의 단부가 경사진입면(84)에 접촉되더라도 경사면을 타고서 중심으로 오므라지면서 코일 끼움공(82)의 내측으로 끼워지게 되는 것이다.At this time, the suspension wire 36 is slightly inclined so that even if the end of the suspension wire 36 is in contact with the inclined entrance face 84, the suspension wire 36 is retracted to the center while being inclined to the center of the coil fitting hole 82. .
따라서, 종래의 서스펜션 와이어 조립방식의 경우는 니퍼와 같은 절단공구로 서스펜션 와이어를 일일이 절단시키므로 작업성이 저하되고 서스펜션 와이어의 낭비가 심하던 것과는 다르게, 본 발명에 따른 서스펜션 와이어 끼움구조를 사용하게 되면 미리 일정길이로 절단된 서스펜션 와이어를 코일피씨비의 코일 끼움돌기에 수평으로 형성된 코일 끼움공으로 바로 끼워 납땜 조립함으로써, 서스펜션 와이어가 낭비되는 것을 방지하여 생산단가를 낮추고, 서스펜션 와이어의 절단 공정이 제거하여 광픽업 액츄에이터의 조립성 및 작업성을 향상시킬 수 있는 효과가 있다.Therefore, in the conventional suspension wire assembly method, since the suspension wire is cut by the cutting tool such as the nippers one by one, the workability is degraded and the waste wire of the suspension wire is severely used, and when the suspension wire fitting structure according to the present invention is used in advance, By soldering the suspension wire cut to a certain length into the coil fitting hole formed horizontally on the coil fitting of the coil PC, the solder wire is assembled to prevent waste of the suspension wire, thereby lowering the production cost and eliminating the cutting process of the suspension wire. There is an effect that can improve the assembly and workability of the actuator.
