Description

Trayless cassette cassette and its automatic drive

Technical field

The present invention relates to a high density trayless cassette cassette and an apparatus for automatically driving the same.

Background technique

The optical disc library is an opto-mechatronic mass data storage device that uses a standardized optical disc as a data storage medium. The optical disc library is connected to the computer through the data communication interface, and the data on all the optical discs in the optical disc library is automatically provided to the user through the management software of the optical disc library. At the same time, the user can easily write data to the disc in the disc library. Therefore, optical disc libraries are widely used for long-term archival preservation of data. The structural principle of the library is shown in Figure 1. The optical disc library consists of a disc drive, an optical drive, a robot assembly and a control unit, wherein the robot assembly includes a robotic dial, a robotic gripper, and a robot displacement device having two axial and horizontal axial movements. The robotic dial and the robotic gripper can be moved up and down with the robot displacement device. The robotic tray is used to pull and push the specified disc tray in the disc magazine, and the robotic gripper is used to grab the disc in the disc tray.

When reading and writing the data of the optical disc, the robot calls the corresponding optical disc according to the instruction of the control unit. At this time, the robot moves to a suitable position, the robotic extractor pulls out the optical disc tray at the designated position in the optical disc, and the mechanical gripper drives the optical disc tray. The optical disc is grabbed from the center hole of the optical disc, and the robotic puller pushes the disc tray back to the closed position. At this time, the robot shifting device transports the robot carrying the optical disc to the position of the designated optical disc drive, and the control unit sends an instruction to send the disc. The tray of the optical drive is opened, the robot puts the loaded optical disc into the optical drive tray, and the control unit sends a command to close the tray of the optical drive, thereby completing the loading process of the optical disc from the optical disc tray to the optical drive. The operation of returning the disc from the optical disc drive to the disc tray is reversed from the above process.

In the prior art, the most occupied space in the optical disc library is the storage portion of the optical disc, which is usually composed of a plurality of modular optical disc cartridges. A typical structure of a commonly used disc cartridge is shown in FIG. 2. Generally, the optical disc cartridge is provided with a plurality of disc trays on which the optical discs are placed, such as the patent ZL200910259495.9, in order to extract the required disc trays by the robot as needed, thereby realizing the above-mentioned function of automatically carrying the optical discs. Obviously, this tray itself takes up a lot of space, and due to mechanical stability, the disc tray cannot be made too thin or too short. Therefore, the light contained in the physical size of the existing optical disc library unit The number of disks is relatively small. Compared with disk and tape, the optical disk library is a near-line storage device, which lags far behind disk arrays and tape libraries in effective space utilization.

In the prior art, another method of placing an optical disc is that although there is no tray in the optical disc cartridge, a sliding groove is provided on the side wall of the optical disc cartridge, and a certain gap between the optical discs of the patent ZL201010538426.4 also takes up. A lot of space, so the space utilization is still not high enough.

Obviously, the most space-saving disc placement method is to stack the discs directly together like a packaged disc package, ie the disc tray is completely omitted. However, the problem with this is that it is not possible to obtain any one of the desired stacked discs using the existing draw-and-catch method. For the form in which such multiple discs are stacked directly, a known method is that the robot gripper grabs one of the uppermost or lowermost discs of the stacked disc each time and repeats this action until it is caught. The disc that you need, in fact, the CD Autoloader and some disc libraries work in this type of scratch. Obviously, for the technical requirements of randomly picking up any disc, the efficiency of this sequential disc capture method is very low, which does not reach the disc speed index of the existing disc library.

On the other hand, the optical disk cartridge of the existing optical disk library is also large in size, and it is inconvenient to exchange the optical disk. The ideal disc size should be similar to modern digital tape, making it easier to transport, exchange and save.

Summary of the invention

The object of the present invention is to provide a trayless cassette cassette and an automatic driving device thereof, which have high storage density, convenient storage and exchange of optical discs, and can automatically take out a disc from the disc and put it into the standard. The automated read and write operations in the optical drive and the automated operation of placing the optical discs in the optical drive back into the optical disk drive provide a core technical foundation for the modular library of optical libraries and offline libraries of various sizes.

In order to solve the problems in the prior art, the technical solution provided by the present invention is:
