Clamping mechanism for storage medium device

Abstract

This utility model relates to the field of storage medium technology, and more particularly to a clamping mechanism for a storage medium device. It includes a longitudinally movable drive base, a push-pull assembly mounted on the drive base capable of pulling a tray out of and pushing it back into the storage compartment, a clamping base mounted on the drive base, and a clamping head mounted on the clamping base capable of being inserted into an optical disc hole. The clamping head is provided with multiple support blocks capable of radially moving along the clamping head, and the outer wall of the support blocks is formed with a contact surface capable of abutting against the wall of the optical disc hole. After the drive base moves longitudinally to be flush with the corresponding tray, the push-pull assembly pulls the tray out of the storage compartment. Subsequently, the drive base moves longitudinally to insert the clamping head into the optical disc hole. The support blocks, capable of radial movement, abut against the wall of the optical disc hole through the contact surface, causing the clamping head to contact the optical disc, thus removing the optical disc from the tray. This mechanism avoids contact with the surface of the optical disc, preventing scratches and effectively protecting the optical disc.

Description

Technical Field

[0001] The utility model relates to the technical field of storage media, in particular to a clamping mechanism of storage medium equipment. Background Art

[0002] Optical discs are becoming increasingly widely used due to their large storage capacity, portability, low price, multiple readability, and resistance to wear. To facilitate the storage and reading of optical discs, there are already some large-capacity optical disc libraries that can automatically pick up optical discs. Such large-capacity automatic optical disc libraries usually have automatic optical disc pick-up and placement devices. Existing automatic optical disc pick-up and placement devices often use clamping and other structural methods, which are not only more complex in structure, but also require a larger movement space, and need to be equipped with a corresponding optical disc storage position with a larger space, resulting in a reduction in the optical disc storage density per unit space of the optical disc library. Therefore, its structural setting is not entirely reasonable. In addition, the existing technology has poor movement stability when grabbing a single optical disc, cannot accurately achieve stable separation of the optical disc when placing the optical disc, has low efficiency in grabbing and placing the optical disc, and the entire process is not simple and fast enough.

[0004] In the above solution, the first and second supporting blocks are used to clamp the top and bottom surfaces of the optical disc.

[0030] The present invention is described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-3As shown, the clamping mechanism of the storage medium device includes a drive seat 43 that can move longitudinally, the drive seat 43 is equipped with a push-pull assembly that can pull the tray out of the storage bin and push it back, the drive seat 43 is equipped with a clamping seat 3, the clamping seat 3 is equipped with a clamping head 1 that can be inserted into the optical disc hole, the clamping head 1 is provided with a plurality of support blocks 13 that can move radially along the clamping head 1, and the outer wall of the support block 13 is formed with a contact surface 16 that can resist the hole wall of the optical disc.

[0032] After the drive seat 43 moves longitudinally until it is flush with the corresponding tray, the tray is pulled out of the storage compartment through the push-pull assembly. Then the drive seat 43 moves longitudinally so that the clamping head 1 is inserted into the disc hole. The support block 13 can move radially through the contact surface 16 to press against the wall of the disc hole, so that the clamping head 1 contacts the disc and can be taken out of the tray; it will not contact the surface of the disc and will not scratch the disc, effectively protecting the disc.

[0033] Preferably, the bottom of the clamping head 1 is in a frustum-shaped structure, so that the outer diameter of the bottom of the clamping head 1 is small, which is convenient for inserting into the hole of the optical disc.

[0034] Preferably, the plurality of support blocks 13 are arranged in an annular shape and at equal intervals on the clamping head 1 . The plurality of support blocks 13 can simultaneously move radially to abut against the hole wall of the optical disc, thereby increasing the contact area and further improving the clamping stability.

[0035] Specifically, the clamping head 1 is formed with a hollow driving cavity 11, and multiple support blocks 13 can move radially along the driving cavity 11. The clamping head 1 is provided with a driving groove 12 that is connected to the driving cavity 11 and for the radial movement of the support blocks 13. When the support blocks 13 retract, they are located in the driving cavity 11, which can protect the support blocks 13; when clamping is required, they move radially in the driving cavity 11 through the driving groove 12 and contact the wall of the optical disc hole.

[0036] Specifically, the drive chamber 11 is provided with a drive structure 2 that drives the support block 13 to move radially. The drive structure 2 includes a rotatable rotating disk 23, and the rotating disk 23 is equipped with a toggle rod 24. The support block 13 is laterally formed with a movable long groove 17 for guiding the movement of the toggle rod 24; when the rotating disk 23 rotates, the toggle rod 24 makes an arc movement accordingly. At this time, the toggle rod 24 can toggle the support block 13 to move, and through the movable cooperation between the toggle rod 24 and the movable long groove 17, the support block 13 is driven to move radially, extending outward or retracting.

[0037] Preferably, the driving structure 2 also includes a guide plate 25 installed in the driving cavity 11, and the guide plate 25 is radially provided with a radial groove 26 for radial movement of the support block 13; the radial groove 26 formed by the guide plate 25 can allow the support block 13 to move radially to prevent the movement from deviating from the set path. When the rotating plate 23 rotates, the support block 13 is driven to move along the radial groove 26 of the guide plate 25 by the toggle rod 24 to ensure the stability of the movement.

[0038] Preferably, the support block 13 includes a contact block 15 having a contact surface 16 and a sliding block 14 slidably installed in the radial groove 26, and the contact block 15 and the sliding block 14 are integrally formed; the sliding block 14 is larger than the contact block 15, and the sliding block 14 slides in cooperation with the radial groove 26, and the outer end of the contact block 15 can be pressed against the wall of the optical disc hole through the contact surface 16.

The drive shaft 21 is installed in the bearing seat 22 to ensure the rotation stability of the drive shaft 21. When the drive shaft 21 rotates, it drives the rotating disk 23 to rotate, thereby realizing radial movement of the support block 13.

[0040] Furthermore, the clamping seat 3 is provided with a driving hole 31, the top of the clamping head 1 is coaxially installed at the bottom of the driving hole 31, and the clamping seat 3 is installed with a telescopic driving member 32. The driving end of the telescopic driving member 32 is rotatably installed with a first connecting rod 33, and the end of the first connecting rod 33 is movably connected to the second connecting rod 34, and the end of the second connecting rod 34 is connected to the top of the driving shaft 21; the driving end of the telescopic driving member 32 performs a telescopic movement, driving the first connecting rod 33 forward or backward, and the second connecting rod 34 can swing. Since the second connecting rod 34 is connected to the top of the driving shaft 21, it can drive the driving shaft 21 to rotate, thereby realizing the rotation of the driving shaft 21 and the radial movement of the support block 13.

[0041] Preferably, the telescopic driving member 32 is a telescopic cylinder or an electric push rod.

[0042] Specifically, the push-pull assembly includes a push block 45 arranged laterally on the drive seat 43. The push block 45 is driven by the belt transmission mechanism 46 to achieve horizontal movement, and then the clamping seat 3 moves longitudinally so that the push block 45 cooperates with the bayonet of the pallet. Then the push block 45 moves laterally to drive the pallet out of the storage bin; when it needs to be pushed back, the push block 45 moves laterally to press against the outer end of the pallet to push the pallet back into the storage bin.

[0043] The clamping mechanism includes a lifting guide mechanism 4 for longitudinal movement of a drive seat 43. The lifting guide mechanism 4 includes a longitudinally arranged guide rail structure 41. A sliding seat 42 is slidably mounted on the guide rail structure 41. The drive seat 43 is mounted on the sliding seat 42. A transmission mechanism is arranged along the length of the guide rail structure 41. The driving end of the transmission mechanism moves longitudinally along the length of the guide rail structure 41. The driving end of the transmission mechanism is connected to the drive seat 43. The transmission mechanism is a transmission belt 44 driven by a motor. The transmission belt 44 is connected to the clamping seat 3 along the transmission seat. The transmission belt 44 moves along the length of the guide rail structure 41 and is connected to the transmission groove of the drive seat 43. Therefore, the clamping seat 3 can move in the vertical direction. The drive seat 43 can be lifted and lowered to align with different pallets in the transverse direction.
