光碟驅動器及其機芯模組 Optical disc drive and its movement module

本發明涉及一種電子設備，尤其涉及一種光碟驅動器及其機芯模組。 The present invention relates to an electronic device, and more particularly to an optical disk drive and a core module thereof.

光碟驅動器的機芯模組為光碟驅動器的核心結構。現有的光碟驅動器的機芯模組都具有設有傾角調整結構，用於調整光學讀取頭髮出的光束的光軸與光碟之間的垂直度，進而確保光學讀取頭的讀寫效果。然而，現有的光學讀取頭傾角調整結構通常直接利用螺絲和彈性元件組合方式進行調整。該彈性元件可為一彈簧，該光學讀取頭傾角調整藉由調節螺絲而擠壓彈簧而調整光學讀取頭傾角。如此，每製造一台光碟播放器就需要額外增加一個或者多個彈性，不僅零件增多且組裝也需要較多時間，導致成本的增加。 The movement module of the disc drive is the core structure of the disc drive. The movement module of the existing optical disc drive has a tilt adjustment structure for adjusting the perpendicularity between the optical axis of the optical beam and the optical disc, thereby ensuring the read and write effect of the optical pickup. However, existing optical pickup tilt adjustment structures are typically adjusted directly using a combination of screws and spring elements. The elastic element can be a spring that adjusts the tilt angle of the optical pickup by adjusting the screw to squeeze the spring. In this way, each time a disc player is manufactured, an additional one or more elasticity is required, which not only increases the number of parts but also requires more time for assembly, resulting in an increase in cost.

鑒於此，有必要提供一種成本較低的光碟驅動器的機芯模組。 In view of this, it is necessary to provide a core module of a lower cost optical disc drive.

The adjusting device 39 is a screw having a substantially cylindrical shape and a cross-sectional area that is in contact with the adjusting device 39 at the first end 31a. The accumulation is large so that the first end 31a can be stably supported by it.

請結合參看圖5，蓋體20固定於承載座10上，用於蓋設承載座10。在本實施方式中，蓋體20藉由鎖合螺釘60與承載座10固定。在其他實施方式中，蓋體20可以藉由扣合或者粘合的方式與承載座10固定。蓋體20與第一通孔11相應地位置上開設有圓形的第二通孔21。蓋體20與第一開口13相應地位置上開設有大致矩形的第二開口23。第二通孔21同樣使主軸馬達40穿過，且主軸馬達40可在其內旋轉。第二開口23比第一開口13的面積小，使光學讀取頭50局部外露並在其內滑動。蓋體20上與導杆30a的第一端31a相對應的位置形成一彈性件25和一開孔27。彈性件25和開孔27是自蓋體20上衝壓而成的。具體地，彈性件25為一彈片，其一體成型于蓋體20上。彈性件25的一端形成于開孔27的孔壁上，另一端向內彎折並穿過開孔27抵壓於導杆30a的第一端31a上並遠離調節裝置39的另一側。因此，導杆30a的第一端31a被穩定地限制於調節裝置39和彈性件25之間。 Referring to FIG. 5, the cover 20 is fixed to the carrier 10 for covering the carrier 10. In the present embodiment, the cover 20 is fixed to the carrier 10 by the locking screw 60. In other embodiments, the cover 20 can be fixed to the carrier 10 by snapping or bonding. The cover body 20 is provided with a circular second through hole 21 at a position corresponding to the first through hole 11. The cover body 20 is provided with a substantially rectangular second opening 23 at a position corresponding to the first opening 13. The second through hole 21 also passes the spindle motor 40, and the spindle motor 40 is rotatable therein. The second opening 23 is smaller than the area of the first opening 13, and the optical pickup 50 is partially exposed and slid therein. An elastic member 25 and an opening 27 are formed in the cover 20 at a position corresponding to the first end 31a of the guide bar 30a. The elastic member 25 and the opening 27 are stamped from the cover 20. Specifically, the elastic member 25 is a spring piece which is integrally formed on the cover body 20. One end of the elastic member 25 is formed on the wall of the opening of the opening 27, and the other end is bent inwardly and passed through the opening 27 against the first end 31a of the guide rod 30a and away from the other side of the adjusting device 39. Therefore, the first end 31a of the guide bar 30a is stably restricted between the adjustment device 39 and the elastic member 25.

主軸馬達40具有一承載面41，用於承載光碟(圖未示)。承載面41藉由第一通孔11和第二通孔21穿出於機芯模組100外。光學讀取頭50具有上表面51。物鏡53位於光學讀取頭50表面所在的一側，並透過第一開口13和第二開口23外露。當承載面41承載光碟時，上表面51與光碟的讀取面相對。物鏡53用於將光學讀取頭50射的光束會聚於光碟的讀取面上或者會聚從光碟讀取面上反射的光束。 The spindle motor 40 has a bearing surface 41 for carrying a compact disc (not shown). The bearing surface 41 passes through the first through hole 11 and the second through hole 21 outside the movement core module 100. The optical pickup 50 has an upper surface 51. The objective lens 53 is located on the side where the surface of the optical pickup 50 is located, and is exposed through the first opening 13 and the second opening 23. When the carrying surface 41 carries the optical disc, the upper surface 51 is opposed to the reading surface of the optical disc. The objective lens 53 is for concentrating the light beam emitted from the optical pickup 50 on the reading surface of the optical disk or condensing the light beam reflected from the optical disk reading surface.

機芯模組100初步組裝完畢後，需藉由調節裝置39來調整導杆30a的高度，使固定於導杆30a和30b的光學讀取頭50的上表面51和主軸馬達40上的光碟承載面41平行，從而使得光學讀取頭50的光軸方向與光碟的方向垂直。因為導杆30a的第一端31a限制於調節裝置39和彈性件25之間，旋轉調節裝置39調節裝置相對導杆30a方向或者背離導杆30a方向移動，從而導杆30a可相對或者背離蓋體20移動，亦即導杆30a沿著光學讀取頭50的光軸方向上下移動，如此達到了調整位於導杆30a和30b上的光學讀取頭50傾角的目的。 After the initial assembly of the movement module 100, the height of the guide rod 30a is adjusted by the adjusting device 39 so that the upper surface 51 and the main surface of the optical pickup 50 fixed to the guide rods 30a and 30b The optical disk bearing surface 41 on the shaft motor 40 is parallel such that the optical axis direction of the optical pickup 50 is perpendicular to the direction of the optical disk. Since the first end 31a of the guide rod 30a is restricted between the adjusting device 39 and the elastic member 25, the rotation adjusting device 39 adjusts the direction of the device relative to the guide rod 30a or away from the guide rod 30a, so that the guide rod 30a can be opposite or away from the cover body The movement of 20, that is, the guide bar 30a moves up and down along the optical axis direction of the optical pickup 50, thus achieving the purpose of adjusting the tilt angle of the optical pickup 50 on the guide bars 30a and 30b.

上述實施方式中，機芯模組100僅在導杆30a的第一端31a相應地位置設置了彈性件25和調節裝置39作為調整光學讀取頭50的傾角調整機構。在其他實施方式中，機芯模組100還可以在導杆30a和30b的第一端31a和31b與第二端33a和33b相應地位置上設置有彈性件25和調節裝置39作為調整光學讀取頭50的傾角調整機構。 In the above embodiment, the movement module 100 is provided with the elastic member 25 and the adjusting device 39 as the inclination adjusting mechanism for adjusting the optical pickup 50 only at the first end 31a of the guide rod 30a. In other embodiments, the movement module 100 can also be provided with an elastic member 25 and an adjustment device 39 at the positions of the first ends 31a and 31b of the guide bars 30a and 30b and the second ends 33a and 33b as adjustment optical readings. The tilt adjustment mechanism of the head 50 is taken.

上述機芯模組藉由調節裝置39和在蓋體20上一體成型的彈性件25，不僅能夠調整光學讀取頭的傾角，且無需額外使用其他彈性元件，不僅減少零件數目且節省了組裝時間，降低了成本。 The above-mentioned movement module can not only adjust the inclination of the optical pickup by the adjusting device 39 and the elastic member 25 integrally formed on the cover 20, and does not need to use other elastic members, thereby reducing the number of parts and saving assembly time. , reducing costs.
