Embodiment 1

[0168] (Embodiment 1, optical pickup core)

[0169] See Figure 21 to Figure 26 , The optical pickup core 5 of the present embodiment includes a base 50, a spindle motor assembly 51, a turntable assembly 52, six slide bar seats 53, a first optical pickup driving component and a second optical pickup driving component.

[0170] See Figure 17 , The base 50 is an integral stamping made of steel, including a bottom plate 50-1 and six shock absorber connection seats 50-2.

[0171] The overall shape of the bottom plate 50-1 is rectangular, with downward folded edges around it, and a long strip-shaped central hole 50-6 as an optical disc reading hole is opened in the center.

[0172] The 6 shock absorber connecting seats 50-2 are divided into two groups, each with 3 shock absorber connecting seats. The left part of the front side, the middle part of the front side and the right part of the front side; the second group of shock absorber connecting seats are equally spaced and conn...

Embodiment 2

[0197] (Embodiment 2, optical pickup core)

[0198] The rest of the optical pick-up movement of the present embodiment is the same as Embodiment 1, the difference is: the middle part of the base plate 50-1 is connected front and back, and the strip central hole 50-6 on the base plate 50-1 is divided into 2 are located on the left and right sides of the bottom plate 50-1, respectively. The spindle motor 51-1 of the spindle motor assembly 51 is fixed on the center of the bottom plate 50-1 by its motor housing.

Embodiment 3

[0199] (Embodiment 3, Suction Disk Loading Device)

[0200] See figure 2 , Image 6 and Figure 17 , the suction-type disk loading device of the present embodiment includes an upper cover assembly 1, an in-and-out disk mechanism 2, a control assembly 3, a transmission mechanism 4, an optical pickup core 5, a pressure plate assembly 6, a baffle assembly 7, a housing 8, a receiving A circuit board 91 , a transmitting circuit board 92 , two wiring boards 93 and five shockproof connectors 94 .

[0201] The optical pickup core 5 in this embodiment is obtained from Embodiment 1. The optical pick-up core 5 also includes 2 blocking posts 50-5 for blocking; the base 50 of the optical pick-up core 5 also includes the left shaft seat plate 50-3 and the right shaft seat plate 50 connected on the base plate 50-1 -4. The left shaft seat plate 50-3 is connected to the base plate 50-1 from top to bottom, and is located on the left of the rear portion of the bottom plate 50-1, and the ri...

Abstract

The invention relates to a suction disk loading device and an optical pickup unit core of the suction disk loading device. The optical pickup unit core is used for reading optical disks of two systems, and comprises a main shaft motor, a first optical pickup unit driver and a second optical pickup unit driver, wherein the main shaft motor is arranged in the center of a bottom plate, and the firstand the second optical pickup unit drivers are respectively arranged below the bottom plate and at the left and the right of the main shaft motor. The suction disk loading device comprises the optical pickup unit core, upper cover assemblies, a disk delivery mechanism, control assemblies, a driving mechanism and disk pressing assemblies. The upper cover assemblies are fixed on the bottom plate ofthe optical pickup unit core. The disk delivery mechanism that is arranged on the upper cover assemblies is a marginal elastically-holding rolling disk-delivery link mechanism, and comprises a link mechanism, a primary roller and a subsidiary roller. A front-side power output member of the driving mechanism is fixedly connected with the primary roller, and a rear-side power output member of the driving mechanism is matched with a controller in the control assemblies. The invention can be used for broadcasting the disks of two different systems, has the advantages of compact structure, high reliability, and causes small damage to the disks.

Description

technical field [0001] The invention relates to a component of an optical disc playing device. Background technique [0002] Traditional DVD requires a light head to emit red laser light with a wavelength of 650nm to read or write data. Blu-ray Disc (Blu-ray Disc) is abbreviated as BD, which uses a shorter blue laser with a wavelength of 405nm to read and write data. Generally speaking, lasers with shorter wavelengths can record or read more information per unit area. Therefore, Blu-ray has greatly improved the storage capacity of optical discs and triggered a leap in the quality of optical storage products. [0003] China's high-definition disc is called CBHD (China Blu-ray High-Definition Disc), which is another blue beam disc product in digital optical storage format. The discs used are similar to BD. They are optical digital storage media with the size of ordinary CDs, and they also use 405 nanometers. wavelength of blue light. The difference is that CBHD can be produ...
