Abstract

1. 청구범위에 기재된 발명이 속한 분야1. Fields to which the invention described in the claims belong

본 발명은 액츄에이터의 래칭시 완충 및 헤드의 데이터존 이탈을 막아주기 위한 크래쉬 스탑(Crash Stop)장치에 관한 것이다.The present invention relates to a crash stop device for preventing buffering and deviation of the head from the data zone when latching the actuator.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

본 발명은 장치를 충격 및 진동으로 인한 결합체의 위치 변화가 잘되지 않는 견고한 결합이 되고 조립이 용이한 크래쉬 스탑 장치 및 액츄에이터 래치장치를 제공하는데 있다.The present invention is to provide a crash stop device and an actuator latch device that is easy to assemble a solid coupling that is difficult to change the position of the assembly due to shock and vibration.

3. 발명의 해결 방법의 요지3. Summary of the Solution of the Invention

본 발명은 보이스코일모터를 구성하는 요오크를 고정시킴에 있어 상부요오크에 끼워지는 크래쉬 스탑에 나사구멍을 형성하여 본딩과 나사체결로 고정시키는 장치이다.The present invention is a device for fixing the yoke constituting the voice coil motor to form a screw hole in the crash stop fitted to the upper yoke to secure by bonding and screwing.

4. 발명의 중요한 용도4. Important uses of the invention

본 발명은 나사를 이용해 크래쉬 스탑을 고정시키므로 조립후 나사 풀림이 발생하지 않는 한 일정한 위치에서 크래쉬 스탑이 있게되어 틀어짐 발생으로 인한 헤드의 위치이동을 막을 수 있으며, 또한 요오크를 본드와 나사로 고정하는 식으로 되어 와란에 의해 떨어지지 않게 되었고, 크레쉬 스탑을 빼내지 않고 재조립이 이루어짐으로 조립공수가 절감되며, 또한 흔들임에 의한 헤드 포지션 변화를 박을 수 있어 제품의 신뢰성이 향상되는 효과가 있다.According to the present invention, the crash stop is fixed by using a screw, so as long as there is a crash stop at a predetermined position unless screw loosening occurs after assembly, it is possible to prevent movement of the head due to twisting and to fix the yoke with a bond and a screw. It does not fall by warrane, and reassembly is made without removing the crash stop, thereby reducing the assembly labor, and also can put the head position change by shaking, thereby improving the reliability of the product.

Claims

An apparatus for fixing an actuator of a hard disk drive, comprising: a disk (10) on which data is recorded, a spindle motor (11) for rotating the disk (10) at a predetermined speed, and a spindle motor (11) at one end thereof. When the disk 10 rotates at a high speed, the disk 10 includes a magnetic head 12 that records or reproduces data at a minute gap, and a rib 13 that adheres to the magnet is attracted to the molding part surrounding the voice coil on the other side. A fastener 17 having a permanent magnet 16 which prevents the parking zone departure of (12) and the voice coil part of the actuator 14 are covered up and down to form a voice coil motor 18. The lower yoke (19a, 19b) and the one side of the upper yoke (19a) is fitted to prevent the head 12 from attempting to escape to the outside direction of the disk, and the bit holder 21 having a tension on one side Screw hole 22a on the other side The actuator latch device of the hard disk drive, characterized in that consisting of a crash stop (22) formed of a buffer material forming a fixed surface (22b).
