Abstract

본 발명은 광픽업 액츄에이터의 트랙킹 코일 조립지그(20)에 관한 것으로, 렌즈홀더(H)에 권취된 포커스 코일(F)의 양측으로 트랙킹 코일(T)을 접착시키도록 한 광픽업 액츄에이터의 트랙킹 코일 조립지그에 있어서, 상부 양단으로는 받침부(1)를 구비하고 상기한 받침부(1)의 내측으로는 관통공(2A)을 갖는 안내구(2)를 각각 부착시킨 몸체(3)와, 상기한 몸체(3)의 안내구(2) 사이에 수직으로 부착되며 상부 일측에는 위치 조정나사(4)를 회동가능하게 축착시키고 상기한 위치 조정나사(4)의 선단으로는 상부에 요홈(5A)이 형성된 렌즈홀더 교정부재(5)를 이동가능하게 결합시킨 렌즈홀더 고정블록(6)과, 고정핀에 의해 몸체(3)의 안내구(2)로부터 회동가능하게 결합되며 돌출부(10A,15A)에 축착된 간격 조정나사(7,11)의 선단에는 이동부재(8,12)를 연결하고 상부 일측과 상기한 이동부재(8,12)에는 코일 삽입구(10B,15A)를 각각 형성하였으며 일측부에는 레버(9,13)를 부착시킨 제1트랙킹 코일 지지블록(10) 및 제2트랙킹 코일 지지블록(15)으로 이루어져 제1트랙킹 코일 지지블록(10) 및 제2트랙킹 코일 지지블록(15)의 회동에 따라 제1트랙킹 코일 지지블록(10) 및 제2트랙킹 코일 지지블록(15)의 코일 삽입구(10B,15B)에 삽입된 트랙킹 코일(T)이 렌즈홀더 고정블록(6)의 상부에 안치된 렌즈홀더(H)의 포커스 코일(F)과 밀착되도록 하는 한편, 제1트랙킹 코일 지지블록(10) 및 제2트랙킹 코일 지지블록(15)의 간격 조정나사(7,11)와 렌즈홀더 고정블록(6)의 위치 조정나사(4)에 의해 트랙킹 코일(T) 사이의 간격 및 포커스 코일(F)과의 결합위치를 미세조절할 수 있으므로 트랙킹 코일(T)과 포커스 코일(F) 이 정확히 결합될 수 있도록 하여 고정밀도와 높은 신뢰성을 갖는 광픽업 액츄에이터를 제작할 수 있으며, 또한 포커스 코일(F)의 양측면에 대한 트랙킹 코일(T)의 부착이 동시에 이루어지므로 트랙킹 코일(T)의 조립작업을 신속하고 용이하게 할 수 있도록 구성한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tracking coil assembling jig 20 of an optical pick-up actuator. In the assembling jig, a body (3) provided with a supporting portion (1) at both ends of the upper part and a guide (2) having a through hole (2A) inside the supporting portion (1), respectively, It is vertically attached between the guides 2 of the body 3, the upper side is rotatably tightened the position adjustment screw 4, the front end of the position adjustment screw 4 to the groove 5A at the top A lens holder fixing block (6) which movably couples the lens holder correcting member (5) formed thereon, and is rotatably coupled from the guide hole (2) of the body (3) by a fixing pin, To the end of the gap adjusting screw (7, 11) condensed on the The first moving coil support block 10 and the second tracking coil support block 15 having the coil insertion holes 10B and 15A formed on the deadline moving members 8 and 12 and the levers 9 and 13 attached to one side thereof, respectively. The coil insertion hole 10B of the first tracking coil support block 10 and the second tracking coil support block 15 according to the rotation of the first tracking coil support block 10 and the second tracking coil support block 15. The tracking coil T inserted into the 15B is in close contact with the focus coil F of the lens holder H placed on the lens holder fixing block 6, and the first tracking coil support block 10 And the distance between the tracking coil T and the focus coil F by the interval adjusting screws 7 and 11 of the second tracking coil support block 15 and the position adjusting screw 4 of the lens holder fixing block 6. The position can be finely adjusted so that the tracking coil (T) and the focus coil (F) can be precisely combined to achieve high precision and The optical pickup actuator with high reliability can be manufactured and the tracking coil T is attached to both sides of the focus coil F at the same time, so that the assembly work of the tracking coil T can be performed quickly and easily. will be.
