Description

Technical Field

[0001] The utility model relates to the technical field of storage media, in particular to a push-pull mechanism of a storage media device. Background Art

[0002] An optical disc library is an opto-mechatronic mass data storage device using standardized optical discs as data storage media, and is widely used for long-term and permanent data storage. The optical disc library may include a plurality of optical disc cartridges and optical disc cases arranged in the optical disc cartridges. During the transportation of the optical disc cartridges or during the use of the optical disc cartridges, there are inevitably usage scenarios of locking and unlocking the optical disc cases and optical disc trays. Optical disc cases are widely used because of their large loading capacity and obvious protection effect on optical discs compared with storage bags. Optical disc cases are mostly placed on the optical disc library for large data volume storage of the optical disc library.

[0003] In the existing storage technologies, hard disks for magnetic storage, USB flash drives (including SD cards) for semiconductor storage, and optical discs for optical storage coexist. However, in an environment with strong electromagnetic fields, the stored information of hard disks for magnetic storage and USB flash drives for semiconductor storage will be damaged, and the information stored in these two can be changed at any time. Only optical storage can ensure that the information will not be changed after being stored, and has stronger confidentiality. Therefore, optical storage is the safest, and optical discs have become an indispensable information carrier medium in today's information society.

[0004] When an optical disc case is transferred, the tray can be withdrawn from the storage bin. The tray is withdrawn from the storage bin through a clamping head. The clamping head can be lifted and lowered to select the corresponding tray to be aligned and then withdrawn or pushed back. When the existing clamping head is lifted and lowered, a guide rod is used as a guiding structure for the lifting and lowering of the clamping head. Usually, two guide rods are arranged in parallel at intervals. Therefore, when guiding and installing, a high installation accuracy is required, which increases the installation difficulty. If the installation accuracy is not high, when the clamping head is lifted and lowered, the contact friction between its sleeve and the guide rod will be relatively large, resulting in a huge noise and causing adverse effects. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a push-pull mechanism of a storage media device aiming at the deficiencies of the prior art.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] The push-pull mechanism of the storage media device includes a clamping seat and a lifting and guiding mechanism for longitudinally moving the clamping seat. The clamping seat is installed with a clamping head for cooperating with the tray. The lifting and guiding mechanism includes a guide rail structure arranged longitudinally. A sliding seat is slidably installed on the guide rail structure. The clamping seat is installed on the sliding seat. A transmission mechanism is arranged along the length direction of the guide rail structure. The driving end of the transmission mechanism longitudinally moves along the length direction of the guide rail structure, and the driving end of the transmission mechanism is connected to the clamping seat.

[0008] Further: The transmission mechanism includes a transmission belt arranged along the length direction of the guide rail structure. The clamping seat is provided with a transmission slot for the transmission belt to pass through, and the transmission belt is fixedly connected to the transmission slot along the way.

[0009] Further: Transmission seats are installed along the transmission belt. The transmission seats are formed with first connection holes, and second connection holes matching the first connection holes are formed around the transmission slot of the clamping seat.

[0010] Further: A rotatable driving wheel is installed at the top of the guide rail structure, and a driven wheel longitudinally aligned with the driving wheel is installed at the bottom of the guide rail structure. The transmission belt is nested between the driving wheel and the driven wheel.

[0011] Further: A top mounting plate is installed at the top of the guide rail structure. A driving motor is installed on the top mounting plate. The driving wheel is installed at the driving end of the driving motor. The top mounting plate is provided with a through slot for the transmission belt to pass through.

[0012] Further: A rear cover is installed on the back of the guide rail structure. A driving cavity with a hollow structure is formed through the rear cover along the length direction, and one long side of the transmission belt passes through the driving cavity.

[0028] The present utility model will be described in detail below with reference to the accompanying drawings.

[0029] As Figures 1-3 shown, the push - pull mechanism of the storage medium device includes a clamping seat 14 and a lifting and guiding mechanism 1 for longitudinally moving the clamping seat 14. The clamping seat 14 is equipped with a clamping head 12 for cooperating with the tray. The lifting and guiding mechanism 1 includes a longitudinally arranged guide rail structure 13. A sliding seat 11 is slidably installed on the guide rail structure 13. The clamping seat 14 is installed on the sliding seat 11. A transmission mechanism is arranged along the length direction of the guide rail structure 13. The driving end of the transmission mechanism longitudinally moves along the length direction of the guide rail structure 13 and is connected to the clamping seat 14.

[0030] When arranging the lifting and guiding mechanism 1, after the guide rail structure 13 is longitudinally arranged, under the drive of the transmission mechanism, the sliding seat 11 can longitudinally move along the guide rail structure 13, thereby driving the clamping seat 14 to lift. This not only ensures the linear stability of the lifting of the clamping seat 14, but also reduces the installation accuracy requirements, greatly improves the installation efficiency, and ensures the movement stability without the phenomenon of frictional noise.

[0031] Specifically, the transmission mechanism includes a transmission belt 15 arranged along the length direction of the guide rail structure 13. The clamping seat 14 is provided with a transmission slot 16 for the transmission belt 15 to pass through. The transmission belt 15 is fixedly connected to the transmission slot 16 along the way. The transmission belt 15 moves along the length direction of the guide rail structure 13 and is connected to the transmission slot 16 of the clamping seat 14 along the way, thereby driving the clamping seat 14 to move in the vertical direction. The clamping seat 14 can move up and down to be horizontally aligned and cooperate with different optical disc trays.

[0032] Furthermore, a transmission seat 17 is installed along the way on the transmission belt 15. The transmission seat 17 is formed with a first connection hole 18, and a second connection hole 19 that cooperates with the first connection hole 18 is formed on the periphery of the transmission slot 16 of the clamping seat 14. The transmission belt 15 is inserted into the transmission slot 16 through the transmission seat 17. Subsequently, the first connection hole 18 formed in the transmission seat 17 is coaxially aligned with the second connection hole 19 on the periphery of the transmission slot 16. After inserting a bolt, the connection is achieved, further improving the connection stability between the transmission belt 15 and the clamping seat 14, preventing the phenomenon of slipping between the transmission belt 15 and the clamping seat 14, and ensuring transmission stability.

[0033] Furthermore, a rotatable driving wheel 21 is installed at the top of the guide rail structure 13, and a driven wheel 22 longitudinally aligned with the driving wheel 21 is installed at the bottom of the guide rail structure 13. The transmission belt 15 is nested between the driving wheel 21 and the driven wheel 22. The driving wheel 21 can rotate. When the driving wheel 21 rotates, it can drive the transmission belt 15 to move along the vertical direction of the guide rail structure 13. The transmission seat 17 of the transmission belt 15 can move up and down in the vertical direction, driving the clamping seat 14 to move longitudinally along the length direction of the guide rail structure 13.

[0034] Furthermore, a top mounting plate 2 is installed at the top of the guide rail structure 13. A driving motor 20 is installed on the top mounting plate 2. The driving wheel 21 is installed at the driving end of the driving motor 20. The top mounting plate 2 is provided with a through slot 23 for the transmission belt 15 to pass through. The driving motor 20 rotates forward and backward to drive the driving wheel 21 to rotate, and the transmission belt 15 installed between the driving wheel 21 and the driven wheel 22 moves accordingly through the through slot 23.

[0035] A rear cover 24 is installed on the back of the guide rail structure 13. The rear cover 24 is formed with a hollow driving cavity 25 running through along the length direction. One long side of the transmission belt 15 passes through the driving cavity 25. The driving cavity 25 can shield one long side of the transmission belt 15, preventing damage to the transmission belt 15 caused by the sputtering of external impurities, and effectively protecting the transmission belt 15.

[0036] At the bottom of the driving cavity 25, a top guide block 26 and a bottom guide block 27 are installed on both sides of the moving direction of the transmission belt 15. The bottom guide block 27 is located at the bottom of the top guide block 26. The driven wheel 22 is rotatably installed on the bottom guide block 27. The top guide block 26 can limit and guide the transmission belt 15 to prevent the transmission belt 15 from shifting laterally. The driven wheel 22 is installed on two bottom guide blocks 27, facilitating the longitudinal connection of the transmission belt 15 between the driving wheel 21 and the driven wheel 22, and further improving the movement stability.

[0037] Furthermore, a sensor 28 is installed on the clamping seat 14, and an induction block 29 cooperating with the sensor 28 is installed on the top of the guide rail structure 13. When the clamping seat 14 moves longitudinally along the guide rail structure 13 through the sliding seat 11 and approaches the top, the sensor 28 on the clamping seat 14 will be inductively coupled with the induction block 29 on the top of the guide rail structure 13. At this time, the sensor 28 will send a pulse signal to the driving motor 20, and the driving motor 20 will pause rotating at this time.

[0038] Preferably, the sensor 28 is a distance sensor 28, which can achieve induction without contact.

[0039] Furthermore, the lifting guide mechanism 1 further includes a support bottom plate 291 installed at the bottom of the guide structure. A plurality of support rods 292 are installed between the top mounting plate 2 and the support bottom plate 291. By connecting the support bottom plate 291 and the top mounting plate 2 through the support rods 292, stable support is achieved.

[0040] In summary, it can be seen that the present utility model has the excellent characteristics described above, enabling it to enhance the effectiveness never before achieved in the prior art during use and having practicality, thus becoming a product with extremely high practical value.

[0041] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
