Optical storage technology is a safe, reliable, green and energy-saving storage technology with long life and low cost. It also has many advantages such as high efficiency, reliability, stability and scalability.

[0003] With the continuous development of optical storage technology, single discs with a capacity of up to 500GB have been put on the market. However, in order to further expand the storage capacity of a single unit, 12 discs are placed in a disc cartridge, so that the capacity of such a disc cartridge can reach 6T. It is precisely because of such advantages that the disc cartridge has been promoted and applied in many fields. When reading and writing the discs in the disc cartridge, a robot or a disc separation mechanism is traditionally used to transport different discs in the disc cartridge to the movement. The structure of the robot is complex, with many parts, and the precision requirements for the processing of parts are very high, resulting in a relatively high overall cost; and although the traditional disc separation mechanism is lower in cost than the robot, the overall volume is relatively large and requires a large space.

[0022] The upper chamber is provided with a movement 9, and a pair of driving protrusions are provided at both ends of the movement 9. The driving protrusions are slidably connected in guide grooves 10 provided on the housing 1, and the guide grooves 10 are longitudinally distributed. Stepped slider assemblies matching the driving protrusions are also provided on both sides of the housing 1.

[0023] The stepped slider assembly includes an upper guide plate 11 and a lower guide plate 12 fixedly connected to the housing 1, and guide grooves matching each other are provided on the upper guide plate 11 and the lower guide plate 12, and the guide grooves are composed of a main groove 13 and a yielding groove 14 that are connected to each other, wherein the yielding grooves 14 are two pairs of symmetrically distributed, and an angle is formed between the yielding grooves 14 and the main grooves 13, and the stepped slider assembly also includes a central slider 15 and a left slider 16 and a right slider 17 located at both ends thereof, and the central slider 15 is provided with an upper step sub-slideway 18 and a lower step sub-slideway 19, and The central axes of the two slides are parallel to each other. A left step slide 20 is provided on the left slider 16, and a right step slide 21 is provided on the right slider 17. When the two ends of the central slider 15 are in contact with the ends of the left slider 16 and the right slider 17 respectively, the upper step branch slide 18 is connected and coaxial with the left step slide 20 to form an upper step main slide, and the lower step branch slide 19 is connected and coaxial with the right step slide 21 to form a lower step main slide. The upper step main slide and the lower step main slide each contain n steps, and there is a smooth rounded transition between adjacent steps.

[0024] The top and bottom surfaces of the central slider 15 are both provided with sliding convex strips 22 slidably connected to the main guide groove 13, and the top and bottom surfaces of the left and right sliders 16 and 17 are both provided with yielding protrusions 23 slidably connected to the main guide groove 13, and the yielding protrusions 23 can enter the yielding guide groove 14.

[0025] A connecting portion 24 is provided on the bottom surface of the central slider 15, and the bottom end of the connecting portion 24 is slidably connected to a slide groove 25 provided on the driving end head 5.

[0026] The two driving protrusions arranged at the ends of the movement 9 are respectively slidably connected to an upper step main slideway and a lower step main slideway in a stepped slider assembly.

[0027] The working process of the folding staggered step slide plate selection mechanism of the embodiment of the present invention is as follows: Figure 1 As shown, there are multiple optical discs (generally 12) evenly distributed in the optical disc magazine in the longitudinal direction. A disc transport mechanism is arranged between the disc selection mechanism and the optical disc magazine. When a certain optical disc needs to be read or written, the movement 9 in the mechanism moves longitudinally relative to the housing 1 until the optical disc entrance on the movement 9 is at the same level as the target optical disc, and then the disc transport mechanism will transport the target optical disc in the optical disc magazine to the movement 9. Since the mechanism adopts a special driving mechanism (stepped slider assembly), the movement 9 moves smoothly and reliably, and can accurately control its lifting height and lock it, so as to ensure that the movement 9 will not shake or move during the reading and writing process of the optical disc. At the same time, it is also provided with a pair of photoelectric sensors 8, which can detect which optical disc the current movement 9 corresponds to, so as to ensure that the disc transport mechanism can accurately transport the target optical disc.

[0028] When it is necessary to drive the movement 9 to make a relative longitudinal movement relative to the housing 1, the control system controls the motor 2 to work, and the motor 2 drives the rotating shaft 3 and the driving plate 4 to rotate through the gear transmission pair. When the driving plate 4 rotates, the driving ends 5 at both ends thereof will slide in opposite directions in the long grooves on the side wall of the housing 1 respectively. Since the driving ends 5 are connected to the connecting portion 24 on the bottom surface of the central slider 15, when the driving plate 4 rotates, the two central sliders 15 will be driven to move in the horizontal direction respectively. Since the driving protrusions at both ends of the movement 9 are slidably connected to the upper step total slideway and the lower step total slideway which are inclinedly distributed, and are slidably connected to the longitudinally distributed guide groove 10 which is opened on the side wall of the housing 1, when the slider moves horizontally, the movement 9 will make a longitudinal movement relative to the housing 1;

[0029] Since the upper stairway and the lower stairway on the two side walls of the housing 1 are inclined in opposite directions, and the driving heads 5 at both ends of the driving plate 4 are running in opposite directions, the driving protrusions at both ends of the movement 9 have the same movement direction (upward or downward at the same time), and since a total of n steps are provided on the upper stairway and the lower stairway, and there is a smooth rounded transition between adjacent steps, the driving head 5 will slide step by step in the upper stairway and the lower stairway, and once the driving head 5 enters a certain step, the step can support it, which can lock it at the current height on the one hand, and can also ensure that the movement 9 remains stable during operation on the other hand;

[0030] During the above movement, when the center slider 15 slides to one side thereof (for example, slides to the left slider 16), the left slider 16 will be pushed to move to the left together in the initial state. At this time, the yielding protrusions 23 at the upper and lower ends of the left slider 16 slide in the main groove 13. When the yielding protrusions 23 move to the connection between the main groove 13 and the yielding guide groove 14, they will automatically enter the yielding guide groove 14 under the guidance of the yielding guide groove 14. Since there is a certain angle between the yielding guide groove 14 and the main groove 13, when the above action occurs, the left slider 16 will move a distance away from the housing 1. It is equivalent to giving up a space slightly larger than its own thickness, and the sliding convex strips 22 set at the upper and lower ends of the central slider 15 cannot enter the giving way guide groove 14, so the central slider 15 will continue to move after crossing the giving way guide groove 14 until the central slider 15 moves to the left end of the main groove 13; this special structure and movement mode can maximize the horizontal movement distance of the slider while ensuring the longitudinal movement stroke (compared with a structure in which a large slider converts horizontal movement into longitudinal movement, the horizontal travel can be saved by about half), thereby greatly reducing the space occupied by the drive mechanism;

[0031] There are n steps in each of the upper step main slideway and the lower step main slideway, and n detection holes 7 are also provided on the sector area 6 on the driving plate 4 that directly drives the movement 9 to move. Here, n should be equal to the number of optical discs stored in an optical disc cartridge. Generally, an existing optical disc cartridge will store 12 optical discs. Here, n is generally 12. If it is for an optical disc cartridge of other specifications, n needs to be equal to the number of optical discs.

[0032] In the initial state, let the movement 9 be at the highest position, and mark the optical discs in the optical disc magazine from top to bottom as disc No. 1, disc No. 2, ... disc No. 12. When the detection hole 7 swings to the position corresponding to the photoelectric sensor 8, the photoelectric sensor 8 is triggered, and the number of times the photoelectric sensor 8 is triggered is consistent with the number of detection holes 7 passed, and also consistent with the number of steps passed by the movement 9. That is to say, through the counting function of the photoelectric sensor 8, it can accurately reveal at which disc the entrance of the movement 9 is currently stopped;

[0033] Assume that now disc No. 3 needs to be taken out, the motor is started, and the driving plate 4 starts to swing. When the photoelectric sensor 8 is triggered three times, it means that the entrance of the movement 9 is just at the height corresponding to disc No. 3. At this time, the control system only needs to control the disc transport mechanism to send disc No. 3 in the optical disc magazine into the movement 9.

[0034] After the read and write operation of disk 3 is completed, suppose disk 8 needs to be taken now. The system first determines that the difference of the disk number is +5, and then controls the driving board 4 to swing in the original direction again. When the photoelectric sensor 8 is triggered five times again, it means that the entrance of the movement 9 is at the same height as disk 8, and the disk transport mechanism can send disk 8 in the optical disk magazine into the movement 9.

[0035] After the read and write operation of disk No. 8 is completed, assuming that disk No. 5 needs to be taken now, the system first determines that the difference in the disk number is -3, and then controls the driving plate 4 to swing in the opposite direction. When the photoelectric sensor 8 is triggered three times again, it means that the entrance of the movement 9 is at the same height as disk No. 5, and the disk transport mechanism can send disk No. 5 in the optical disk cartridge into the movement 9.

[0036] After the operation is completed, the movement 9 is controlled to return to the initial position and wait for the next operation.
