Abstract

본 발명은 광픽업의 액츄에이터 조립지그에 관한 것으로 특히 흘더 렌즈(111)를 홈(112)에 끼워지는 조립지그(100)의 돌부(113)에 의해 잡아줌으로서 홀더렌즈(111)가 X, Y방향으로 움직이지 못하게 하는 동시에 조립 지그(100)에 나사(201)로 체결되는 플레이트200에 의해 홀더렌즈(111)가 Z방향으로도 움직이지 못하게 함으로서 홀더렌즈(111)의 소정위치에 서스펜션 와이어(109)를 납땜 작업 할 수 있게 하며, 조립지그(100)에 자석 또는 전자석을 설치하여 자력이 요크(110)의 저면에 균일하게 작용하도록 함으로서 조립지그(170)에 안착되는 요크(110) 저면의 평탄도가 불량하더라도 균일하게 작용하는 자력에 의해 요크(110)클 조립지그(100)에 안정되게 안착시킬 수 있게 한 광픽업의 조립지그에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an actuator assembly jig for optical pickup, and in particular, the holder lens 111 is X, Y by holding the header lens 111 by the protrusion 113 of the assembly jig 100 fitted into the groove 112. The holder lens 111 does not move even in the Z direction by the plate 200 fastened to the assembly jig 100 with the screw 201. 109 can be soldered, and a magnet or an electromagnet is installed on the assembly jig 100 so that the magnetic force acts uniformly on the bottom surface of the yoke 110 so that the bottom of the yoke 110 seated on the assembly jig 170 is fixed. Even if the flatness is poor, it relates to the assembly jig of the optical pickup that can be stably seated in the yoke (110) assembly jig 100 by the magnetic force acting uniformly.
