광픽업 액츄에이터용 렌즈 보호커버{Lens protection cover for optical pick-up actuator}Lens protection cover for optical pick-up actuator

본 발명은 광픽업 액츄에이터용 렌즈 보호커버에 관한 것으로서, 좀더 상세하게는 조립이 완성된 액츄에이터에 있어, 액츄에이더에 조립 설치되는 픽업커버의외관에 별도로 씌워져 보관상태를 유지시키기 위한 보호 커버를 개선하여 사용자로 하여금 제품의 사용되기 이전 운반이나 보관상태에서 안전하게 액츄에이터를 보호 및 유지관리하기에 용이하도록 한 것이다.The present invention relates to a lens protective cover for an optical pickup actuator, and more particularly, in an actuator in which an assembly is completed, the protective cover for maintaining a storage state is separately covered by an outer cover of a pickup cover assembled and installed on the actuator. This makes it easy for users to protect and maintain the actuator safely in the transport or storage state before the product is used.

일반적으로, 컴팩트 디스크 플레이어와 같은 광픽업 액츄에이터를 이용한 광학기기 등은 각종 음성신호 혹은 영상신호가 입력된 디스크(Disc)를 광학기기 내에 장착시키고, 그 디스크를 턴테이블 저면에 설치된 스핀들 모터를 회전시켜서 디스크에 내재된 데이터를 광픽업 액츄에이터를 통해 신호화하여 이를 재생시킴으로써 사용자가 음성신호를 듣거나 영상신호를 디스플레이 하여서 보게 하도록 해주는 재생기기이다.In general, optical devices using optical pickup actuators, such as compact disc players, mount discs in which various audio signals or video signals are input into the optical devices, and rotate the discs by rotating the spindle motor installed on the bottom of the turntable. It is a playback device that allows the user to listen to the audio signal or display the video signal by displaying the data inherent in the optical pickup actuator to reproduce the signal.

상기와 같은 광픽업 장치에서는 픽업구동에 따른 광디스크로부터 정보를 읽기 위한 액츄에이터는 단품상으로 조립 설치됨에 있어, 상부에는 블레이드상의 대물렌즈 및 서스펜션와이어를 외부의 충격으로부터 내부 구조물의 보호 방지하기 위한 픽업 커버가 설치된다.In the optical pick-up device as described above, the actuator for reading information from the optical disk according to the pickup drive is installed in a single unit, so that the pickup cover for protecting the inner structure of the objective lens and suspension wire on the blade from external impacts Is installed.

한편, 상기와 같은 상태의 액츄에이터는 단품으로 광픽업 기기의 데크로부터 조립되어 완제품으로 출시되기 이전에 보관 및 이를 유지해야 하는데, 특히, 액츄에이터의 대물렌즈부분은 공기 중에 포함된 이물질이나 습도에 의해 오염됨을 방지하기 위한 목적으로 상기 픽업커버 상에 양면 테이프가 적용된 시트(Sheet)를 부착하여 대물렌즈를 보호할 수 있도록 하였다.On the other hand, the actuator as described above must be stored and maintained before assembling from the deck of the optical pickup device as a single product and released to the finished product, in particular, the objective lens portion of the actuator is contaminated by foreign matter or humidity contained in the air In order to prevent the possibility of attaching a sheet (Sheet) to which the double-sided tape is applied on the pickup cover to protect the objective lens.

상기와 같은 양면 테이프의 사용은 사용당시 편리함은 있으나, 제품 조립 적용시 다시 떼어내어야 하는 번거로움이 있으며, 떼어낸 부분으로부터 잔존하는 접착물질을 완전 제거해 주어야 하는 불편함이 있었고, 양면 테이프는 일회용 용도로 사용되기 때문에 후 처리와 함께 비경제적인 문제점이 있었다.Although the use of the double-sided tape as described above is convenient at the time of use, there is a hassle that needs to be removed again when applying the product assembly, and the inconvenience of having to completely remove the remaining adhesive material from the removed portion, the double-sided tape is disposable There was an uneconomical problem with post-treatment because it was used as.

상기와 같은 점을 고려하여 종래에는 첨부된 도 1에서 도시된 바와 같이, 액츄에이터(10)의 픽업커버(11)형상에 맞는 보호커버(20)를 별도로 끼움 설치함으로써, 대물렌즈를 보호할 수 있도록 한 바 있다. 상기 보호커버(20)는 얇은 PET소재로서 사출 제작한 것으로, 픽업커버에 끼움 설치됨에 있어, 상기 보호커버는 경제적으로 이용하기 위한 목적에서 얇게 형성되어 있기 때문에, 사출제작 상에서 상기 픽업커버를 수용하기 위한 사이즈가 오버되거나 미달되는 사례가 있어, 이를 상기 픽업커버에 적용했을 때 액츄에이터의 운반도중 보호커버가 액츄에이터의 픽업커버로부터 쉽게 이탈되는 단점이 있었다. 또는 사이즈가 작을 경우에는 사용하지 못하는 폐단이 있었다.In consideration of the above, as shown in FIG. 1, the protective cover 20 that fits in the shape of the pickup cover 11 of the actuator 10 is separately installed to protect the objective lens. I've done it.

There is a case in which the size is over or under, there is a disadvantage that the protective cover is easily separated from the pickup cover of the actuator during the transport of the actuator when it is applied to the pickup cover. Or if the size is small, there was a lung can not be used.

이는 곧 대물렌즈를 오염시키는 원인이 되기도 하며, 대물렌즈 보호를 위해 생산된 별도의 보호커버 일부는 그대로 버릴 수밖에 없는 비경제적인 문제점이 있었다.This may soon cause contamination of the objective lens, and there is an uneconomic problem inevitably throwing away some of the separate protective cover produced for the objective lens protection.

본 발명은 상술한 바와 같이 제반되는 문제를 해결하기 위하여 안출한 것으로, 그 목적은 광픽업 액츄에이터의 픽업커버의 상면으로부터 보호커버를 용이하게 착탈할 수 있도록 하여 대물렌즈를 안정적으로 보호함은 물론, 광픽업 제품의 생산공정 및 보관, 출하시 액츄에이터의 보관 및 조립상태 유지에 따른 보호커버를 회수하여 반복적인 재사용이 가능하도록 한 광픽업 액츄에이터용 렌즈 보호커버를 제공하는데 있다.The present invention has been made in view of the above-described problems, the object of which is that the protective cover can be easily detached from the upper surface of the pickup cover of the optical pickup actuator, as well as stably protect the objective lens, The present invention provides a lens protective cover for an optical pickup actuator that enables the repetitive reuse of the protective cover according to the production process and storage of the optical pickup product, the storage of the actuator during the shipment, and the maintenance of the assembled state.

상기 목적을 달성하기 위해 본 발명에 의하면, 광픽업 액츄에이터의 픽업커버 상에 끼움 설치되는 렌즈 보호커버에 있어서, 상기 보호커버는 픽업커버를 상부로부터 수용하기 위한 본체의 내측둘레에 돌출 형성되는 걸림부와, 상부로부터 돌출 형성되어 렌즈로부터 이격되는 돌출부와, 본체 일측에 연장 형성되는 손잡이부로 구성된 것을 특징이다.According to the present invention in order to achieve the above object, in the lens protective cover fitted on the pickup cover of the optical pickup actuator, the protective cover is a locking portion protruding on the inner circumference of the main body for receiving the pickup cover from the top And a protrusion formed to protrude from an upper portion and spaced apart from the lens, and a handle portion extended to one side of the main body.
