Abstract

본 발명은 광디스크플레이어용 광픽업엑츄에이터에 관한 것으로, 길이방향 일측면상에 레이저빔통과공이 형성되고, 반대쪽 양측으로부터 상방향으로 소정높이의 댐핑겔 플레이트가 일체로 절곡되며, 중앙부에는 그 길이방향 중심선상에 요오크부가 일체로 돌설된 베이스플레이트와, 상기 베이스플레이트상에 형성된 레이저빔통과공과 대응되는 일측면에 대물렌즈장착을 위한 대물렌즈장착공이 형성되고, 저면에는 트랙킹조절코일 및 포커싱조정코일이 설치되는 코일권선부가 일정간격으로 일체로 형성되며, 양측면 소정위치에는 서스펜션을 끼우기 위한 서스펜션삽입편이 일체로 돌설되는 한편, 상기 코일권선부 사이에는 밸런서가 장착된 대물렌즈홀더와, 상기 요요크부에 끼워지는 단일의 영구자석으로 구성하므로써 구조를 단순화시킴과 동시에 작업성 및 생산성을 현저히 향상시킬수 있도록 한 것이다.The present invention relates to an optical pickup actuator for an optical disc player, wherein a laser beam through hole is formed on one side of a longitudinal direction, and a damping gel plate of a predetermined height is bent integrally upward from both sides of the opposing side, and a center line is formed on the longitudinal center line thereof. A base plate having an integrally formed yoke portion, and an objective lens mounting hole for mounting an objective lens on one side corresponding to the laser beam passing hole formed on the base plate, and a tracking adjustment coil and a focusing adjustment coil are installed on the bottom surface thereof. The coil windings are integrally formed at predetermined intervals, and suspension insertion pieces for fitting the suspensions are integrally protruded at predetermined positions on both sides, while an objective lens holder equipped with a balancer is inserted between the coil windings and the yoke portion. The paper is composed of a single permanent magnet to simplify the structure and It will allow you to sikilsu significantly improve the workability and productivity.
