[0002] Optical storage is a data storage technology that uses optical discs as storage media. It is very suitable for long-term cold data storage because of its advantages such as energy saving, reliability and durability. In order to increase the storage space capacity, the optical disc storage on the market currently puts multiple optical discs in the storage device, and these optical discs require special storage trays. When reading and writing data in the optical disc storage, it is necessary to separate the multiple optical discs stacked together, take out the specified optical disc, and put it into the optical drive for reading and writing. This process requires an efficient, stable and reliable optical disc robot to complete the disc retrieval and separation functions.

[0003] Currently, the optical disk manipulators of the optical disk storage products on the market mostly use a connecting rod mechanism to drive the manipulator claws to achieve the disk retrieval and separation functions. Most of them have defects such as complex structure and low reliability, which makes the optical disk storage cost high and has many undesirable phenomena, restricting the development of the optical storage industry.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] Embodiment 1:

[0064] like Figure 1-2 The optical disk robot disclosed in this embodiment includes a sleeve 11 and a rotating shaft 13 and a track module 14 arranged in the sleeve;

[0065] The track module 14 includes a fixed track plate 141 fixed in the sleeve, and an upper rotating track plate group 142 and a lower rotating track plate group 143 respectively arranged on the upper and lower sides of the fixed track plate 141, and the upper rotating track plate group 142 and the lower rotating track plate group 143 both have a rotating track 144, and the claws of the upper rotating track plate group 142 and the claws of the lower rotating track plate group 143 are arranged in the rotating track 144 near the tail end of the rotating shaft, and the main body of the claw away from the tail end can be slidably arranged in the sliding track 145 on the fixed track plate 141;

[0066] The rotating shaft 13 passes through the upper rotating track plate group 142 and the lower rotating track plate group 143, and the rotating shaft 13 can drive the upper rotating track plate group 142 and the lower rotating track plate group 143 to rotate, thereby driving the tail end of the claw to move along the rotating track 144, and driving the main body of the claw to reciprocate in the sliding track 145 so that the front end of the claw extends out of or retracts into the sleeve 11, and the action of taking and placing the optical disc 2 is completed through the telescopic cooperation of the claw of the upper rotating track plate group 142 and the claw of the lower rotating track plate group 143.

[0067] The present invention can realize the extension or retraction of the sleeve by driving the claw through the provided rotating track and sliding track in coordination with the rotation of the rotating shaft, and realize the disk grabbing and disk placing actions through the telescopic coordination of the claws of the upper rotating track plate group and the claws of the lower rotating track plate group. The present invention disassembles the complex manipulator motion mechanism into simple and reliable linear motion, and can realize stable and reliable disk retrieval and separation functions. The structure of the manipulator is simple, the cost is low, and it is convenient for large-scale production and application.

[0068] In a specific embodiment, Figure 5 As shown, an upper active tooth 131 and a lower active tooth 132 are sequentially arranged on the outer wall of the rotating shaft 13 from top to bottom, and the upper active tooth and the lower active tooth are both provided with toothed areas and toothless areas alternately arranged in sequence along their respective circumferential directions, and the toothed areas and toothless areas of the upper active tooth are staggered with the toothed areas and toothless areas of the lower active tooth;

[0069] Specifically, in this embodiment, a driven gear fixing shaft 147 is provided on the rotating track plate, the driven gear is mounted on the driven gear fixing shaft and fixed by a retaining spring 148, the driven gear is driven to rotate by the driving gear, and the driven gear drives the rotating track plate to rotate through the driving gear fixing shaft; retaining springs 148 are also installed on the upper side of the upper driving gear and the lower side of the lower driving gear on the rotating shaft to prevent axial displacement thereof;

[0070] The sliding rails 145 are provided on the upper and lower surfaces of the fixed rail plate 141 along the radial direction;

[0071] The upper rotating track plate set 142 and the lower rotating track plate set 143 have the same structure, and are symmetrically arranged on the upper and lower sides of the fixed track plate 141. Figure 3-4 As shown, the upper rotating track plate group 142 and the lower rotating track plate group 143 both include a rotating track plate, a driven tooth and the claw, the driven tooth is fixed to the rotating track plate, the rotating track 144 is arranged in the rotating track plate, and the rotating track 144 includes a disk taking track area 1441 and a disk placing track area 1442 which are alternately arranged in sequence and connected along the circumferential direction of the rotating track plate;

[0072] A rotating shaft 146 is fixed to one side of the tail end of the claw, and the rotating shaft is arranged in the rotating track 144, and the side of the main part of the claw away from the rotating shaft is always arranged in the sliding track 145; when the rotating shaft rotates, the toothed area of ​​the upper active tooth 131 and the toothed area of ​​the lower active tooth 132 are engaged with the driven tooth to drive the rotating track plate to rotate, and the rotation of the rotating track plate drives the rotating shaft 146 to move in the rotating track 144 and drives the claw to slide radially in the sliding track 145. When the rotating shaft moves to the disk-taking track area 1441, the driving claw moves radially in the sliding track 145 so that the front end of the claw extends out of the sleeve. When the rotating shaft moves from the disk-taking track area 1441 to the disk-putting track area 1442, the driving claw moves radially in the sliding track 145 so that the front end of the claw retracts into the sleeve; when the rotating shaft rotates to the toothless area of ​​the active tooth opposite to the driven tooth, the claw maintains the previous state of extending or retracting the sleeve unchanged.

[0073] Specifically, when the rotating shaft 13 rotates, the upper active tooth 131 on the rotating shaft rotates coaxially therewith, and when the toothed area of ​​the upper active tooth rotates to mesh with the upper driven tooth 1422 of the upper rotating track plate set 142, as the rotating shaft 13 continues to rotate, the upper rotating track plate 1423 can be driven to rotate, thereby driving the rotating shaft connected to the tail end of the upper claw 1421 to move in the rotating track 144, and then driving the upper claw 1421 of the upper rotating track plate set 142 to move radially in the sliding track 145 and extend out of the sleeve 11. Or retract the sleeve, when the toothless area of ​​the upper active tooth rotates to be opposite to the driven tooth of the upper rotating track plate group 142, that is, the upper active tooth does not mesh with the driven tooth, during this process, the upper claw of the upper rotating track plate group 142 maintains the previous position state (the front end of the upper claw extends out of the sleeve or retracts into the sleeve). Similarly, when the rotating shaft rotates, the lower active tooth rotates with it, and when the toothed area of ​​the lower active tooth rotates to mesh with the lower driven tooth 1432 of the lower rotating track plate group 143, as the rotating shaft continues to rotate, it can drive The lower rotating track plate 1433 rotates, thereby driving the rotating shaft connected to the tail end of the lower claw to move in the rotating track 144, and then driving the lower claw 1431 of the lower rotating track plate group 143 to move radially in the sliding track 145 to extend out of the sleeve or retract the sleeve. When the toothless area of ​​the lower active tooth rotates to be opposite to the driven tooth of the lower rotating track plate group 143, that is, the lower active tooth does not mesh with the driven tooth, during this process, the lower claw of the lower rotating track plate group 143 maintains the front end of the claw in the previous position to extend out of the sleeve or retract The sleeve remains unchanged; and because the toothed area and the toothless area of ​​the upper active teeth are staggered with the toothed area and the toothless area of ​​the lower active teeth, the upper active teeth and the lower active teeth of the rotating shaft can respectively drive the upper clamping claw of the upper rotating track plate group 142 and the lower clamping claw of the lower rotating track plate group 143 to extend and retract respectively, so the upper clamping claw can cooperate with the lower clamping claw to realize the taking and placing of a single or multiple optical discs 2; in this embodiment, the number of the upper clamping claw and the lower clamping claw is set to three, and the upper clamping claw and the lower clamping claw are evenly distributed on their respective rotating track plates,

[0074] Fig.10 It is a schematic diagram of the toothed area and the toothless area of ​​the upper active gear and the lower active gear. Fig.10 (a) is the upper driving gear, Fig.10 (b) is the lower active gear, in which the black dot indicates the initial position. The upper active gear includes toothed areas g1-2, g1-4, g1-6 and toothless areas g1-1, g1-3, g1-5. The lower active gear includes toothed areas g2-1, g2-3, g2-5 and toothless areas g2-2, g2-4, g2-6. The tooth areas of the upper active gear and the lower active gear are staggered and installed on the rotating shaft.

[0075] like Fig.11The schematic diagram of the working process of the optical disk manipulator is shown. When the control system of the optical disk storage device (the control system is a prior art, and its principle is not described here) issues an instruction to read and write a certain disk, the gearbox 6 starts to drive the rotating shaft to rotate forward or reverse, and drives the manipulator to move up and down along the guide rod under the drive of the lifting screw to realize the lifting and lowering of the optical disk. The following describes the movement principle (process) of the manipulator when taking and separating the optical disk:

[0076] t0: Initial state see Fig.11 In the t0 stage, the starting point (black dot) of the upper active tooth 131 contacts the upper driven tooth 1422, and the starting point (black dot) of the lower active tooth 132 contacts the lower driven tooth 1432, and the initial positions of the upper and lower active teeth are not consistent; Fig.11 As shown, the upper clamping claw 1421 and the lower clamping claw 1431 are both in the retracted state;

[0077] t0→t1: When the nth disc from the top of the optical disc magazine 3 needs to be read or written, the manipulator 1 is driven by the lifting screw 81 to descend to the designated position of the optical disc magazine, and the gearbox 6 drives the driving tooth 134 of the manipulator 1 to rotate, thereby driving the rotating shaft 13 and the active tooth fixed thereon to rotate; the g1-1 toothless area of ​​the upper active tooth 131 is opposite to the upper driven tooth 1422, and the upper claw 1421 maintains a retracted state; the g2-1 toothed area of ​​the lower active tooth 132 is meshed with the lower driven tooth 1432, and the lower claw moves in the rotating track and away from the axis, see Fig.11 In the stage t0→t1, the lower claw 1431 becomes extended, and the robot takes out n discs from the optical disc magazine;

[0078] t1→t2: the rotating shaft continues to rotate, the toothless area g2-2 on the lower active tooth 132 is opposite to the lower driven tooth 1432, the lower claw 1431 remains in the extended state, the toothed area g1-2 of the upper active tooth 131 meshes with the upper driven tooth 1422, the upper claw 1421 extends and penetrates between the nth optical disc and the n-1th optical disc, separating the nth optical disc from the n-1th optical disc;

[0079] t2→t3: The rotating shaft 13 continues to rotate, the toothless area g1-3 of the upper driving tooth 131 is opposite to the upper driven tooth 1422, the upper rotating track plate 1423 and the upper clamping claw 1421 remain in the extended state, still grabbing the n-1 optical disc above, the toothed area g2-3 of the lower driving tooth 132 is meshed with the lower driven tooth 1432, the lower rotating track plate 1433 drives the lower clamping claw 1431 thereon to retract, and the nth disc is placed on the optical drive tray 41;

[0080] t3→t4: the rotating shaft continues to rotate, the toothed area g1-4 of the upper driving tooth 131 meshes with the upper driven tooth 1422, the toothless area g2-4 of the lower driving tooth 132 is opposite to the lower driven tooth 1432, the upper claw 1421 retracts, and the upper n-1 optical disc is put back into the optical disc tray 3;

[0081] When the optical disc 2 is finished reading or writing and needs to be put back into the optical disc tray 3, the following steps are followed:

[0082] t4→t5: The optical disc robot 1 is driven by the lifting device 8 to descend into the optical disc tray 3, the rotating shaft is reversed, the toothed area g1-4 of the upper driving teeth 131 meshes with the driven teeth, the toothless area g2-4 of the lower driving teeth 132 is opposite to the driven teeth, the upper claw extends, and the upper claw grabs the upper n-1 optical discs from the optical disc tray, and is driven by the lifting device to rise above the optical drive tray 41, and the next action is performed after the optical drive tray is extended;

[0083] t5→t6: The optical disk robot 1 is driven by the lifting device 8 to descend to the optical disk tray, and the rotating shaft continues to reverse. The toothless area g1-3 of the upper driving tooth 131 is opposite to the upper driven tooth 1422, and the toothed area g2-3 of the lower driving tooth 132 is meshed with the driven tooth. The lower gripper extends to grab the optical disk in the optical disk tray, that is, the nth disk;

[0084] t6→t7: The rotating shaft rotates forward, the toothless area g1-3 of the upper driving tooth 131 is opposite to the upper driven tooth 1422, the toothed area g2-3 of the lower driving tooth 132 is meshed with the lower driven tooth 1432, the lower claw retracts, and the nth disk is put down;

[0085] t7→t8: The rotating shaft rotates forward, the toothed area g1-4 of the upper driving tooth 131 meshes with the upper driven tooth 1422, the toothless area g2-4 of the lower driving tooth 132 is opposite to the lower driven tooth 1432, the upper claw retracts, and the upper n-1 disk is put down;

[0086] At this point, the removal, distribution and return of a single CD are completed.

[0087] If there are more than two optical drives in the optical storage device, refer to Fig.12 The flowchart of the process of taking out, distributing and returning multiple optical discs is shown below:

[0088] When you need to read and write CDs in two CD-ROM drives, Fig.12From t0 to t8, the nth optical disc and the n-1th optical disc can be taken out and distributed, and the n-2th optical disc can be sent back to the optical disc magazine. When the reading and writing are completed and the optical disc 2 in the two optical drive trays 41 needs to be put back into the optical disc magazine, the robot moves, first takes out the n-2th optical disc in the optical disc magazine through the upper claw, takes out the nth optical disc in the optical drive tray and puts the nth optical disc back into the optical disc magazine, then takes out the n-1th optical disc in the other optical drive tray and puts it back into the optical disc magazine, and finally puts the n-2th optical disc back into the optical disc magazine, see Fig.12 t8→t14.

[0089] In a specific embodiment, the radial distance from the disk-taking track area 1441 to the rotating shaft is greater than the radial distance from the disk-placing track area 1442 to the rotating shaft. That is, the rotating shaft arranged in the rotating track 144 can enter the disk-taking track area 1441 and the disk-placing track area 1442 under the drive of the rotating track plate. When the rotating shaft is in the disk-taking track area 1441, the distance between the rotating shaft and the axis of the rotating shaft is relatively far. At this time, the rotating shaft drives the claw to move outward in the sliding track 145 through the tail end of the claw, so that the front end of the claw extends out of the sleeve through the claw outlet and overlaps the lower surface of the optical disc. When the claw is extended, the diameter of the circle where the front end of the claw is located is larger than the center hole of the optical disc 2, thereby achieving the grasping of the optical disc, such as Figure 8 (b) shows that the rotation axis of the lower clamping claw moves into the disc removal track area, and the lower clamping claw extends out of the sleeve to the lower side of the disc. Fig. 9 Schematic diagram of the claw inserted into the gap of the optical disc; when the rotating track plate continues to rotate and drives the rotating shaft to move into the disc placement track area 1442, the distance between the rotating shaft and the axis of the rotating shaft is relatively close. At this time, the rotating shaft drives the claw through the tail end of the claw to move inward in the sliding track 145 until the front end of the claw is retracted into the sleeve, thereby achieving disc placement.
