Description
Technical field
The utility model relates to a kind of blue laser video disc player movement.
Background technology
The core component of VCD player is a movement, and the basal disc seat is important product on the movement, is the basis of cassette mechanism structure, and whole parts all are installed on the basal disc seat.The blue light video disc player of popular in the market a kind of high sharpness video and mass data storage is called for short BD.The BD technical standard of being issued according to BD groups such as Sony, Philip, Panasonics, be that blue light video disc player or Blu-ray Disc all are that price can be in any more at present, the blue-ray laser head high enterprise of price especially wherein, so cheap again movement of a kind of existing BD characteristics of market in urgent need (being HD video and mass data storage), just the mentioned MiniBD movement of the utility model is called for short MBD movement (being little blue light movement again).In fact little blue light is not traditional blue light, but reads with ruddiness, and it is to be the AVC video of storage medium with the D5/D9 disc, and by the specific video decode system, it can reach the high-resolution image quality of 1080P.Just allow you with the price of traditional DVD, enjoy the 1080P high-quality movie in high definition epoch! And the blue-ray DVD form has the message transmission rate of 36MB/s, and adopts the compress mode of MPEG-2 as Streaming Media, and the standards for digital broadcasting with the whole world keeps compatible.The memory capacity of blue-ray DVD single-surface single-layer disc is defined as 23.3GB, 25GB and 27GB, and wherein peak capacity (27GB) is nearly 6 times of current ruddiness DVD single-surface single-layer disc capacity (4.7GB).
The blue light video disc player is to read file on the dish with blue laser.Because red light wavelength has 700 nanometers, and blue light has only 400 nanometers, and is shorter because of blue light wavelength, so blue laser is in fact more accurate, can read the bigger CD of density.Can read and write a point that has only 200nm, and by contrast, red laser can only be read and write the point of 350nm, so a same CD, point is how, and the information of record is also just how naturally!
Blu-Ray Disk is a Blu-ray disc, be one of follow-on standard of DVD, storage principle is the groove recording mode, adopts traditional groove to carry out record, yet realized more jumbo storage and data management by the advanced more addressing of shivering, reached the 100GB that surprises the world at present.Compare with traditional CD or DVD file layout, the BD CD obviously brings better reflectivity and storage density, and this is the key that its realization capacity is broken through.
Above-mentioned videodisc machine core comprises a basal disc seat, be arranged on the high-speed brushless motor on the basal disc seat, holder of fixedlying connected with the high-speed brushless motor with the basal disc seat and the stepper motor that is connected with screw mandrel, driving rack, leading rod, secondary guide rod and the laser head that can on leading rod and secondary guide rod, slide, laser head and driving rack are connected, under the drive of the described stepper motor that is fixed with screw mandrel, by screw mandrel and driving rack transmission, laser head is along guide rod gliding motility back and forth, standard size 24.5mm between video disc center of rotation and the laser head leading rod its role is to guarantee in the accuracy of LD laser light fixed fire at video disc pits spot central point! Help providing laser head to read the error correcting capability of dish, off-centre.
Existing blue light movement has accurately adopted structure as shown in Figure 1 for guaranteeing the distance between leading rod and the crystalline flake of iodine center of rotation, leading rod 1 immobilizes, adjust the standard size that (Spindle Motor) holder 2 moves video disc center of rotation transverse horizontal to guarantee itself and leading rod, its pattern mainly relies on special fixture to guarantee in size correction that produce to adjust fit on, and adjustment process complexity, time are long.And the adjustment consistance be cannot say for sure to demonstrate,prove! Often its adjusting process becomes the operation bottleneck of whole production technology! Cause production cost height, efficient extremely low!
The utility model content
The utility model provides a kind of blue laser video disc player movement, serves as the accurate employed complicated adjusting process of distance that guarantees between leading rod and the limited post to solve existing videodisc machine core, and is difficult to guarantee conforming technical matters.
In order to solve above technical matters, the technical scheme that the utility model is taked is:
A kind of blue laser video disc player movement, holder that comprises a basal disc seat, is arranged on high-speed brushless motor on the basal disc seat, fixedlys connected with the high-speed brushless motor with the basal disc seat and the stepper motor that is connected with screw mandrel, driving rack, leading rod, secondary guide rod and the laser head that can on leading rod and secondary guide rod, slide, described laser head and driving rack are connected, under the drive of the described stepper motor that is fixed with screw mandrel, by screw mandrel and driving rack transmission, laser head is along guide rod gliding motility back and forth; It is characterized in that described leading rod is locked on the basal disc seat, described holder is provided with limited post, be locked on the basal disc seat after being connected with high-speed electric expreess locomotive, described leading rod and described limited post near.
Described limited post is the bending projection.
After having adopted technique scheme, owing to be locked on the basal disc seat after holder and high-speed brushless motor (being the video disc center of rotation) are connected, and leading rod also is locked on the basal disc seat after near the limited post on the holder, just can not guarantee that the distance between video disc center of rotation and the leading rod is set to 24.5mm so do not need to carry out complicated adjustment, simultaneously when producing assembling, also saved great amount of manpower, solved existing videodisc machine core be difficult to guarantee between video disc center of rotation and the leading rod apart from the accurate technique problem.
