Description

Easy radiating carousel formula CD-ROM

Technical Field

The utility model relates to an optical storage device technical field, more specifically relates to an easily radiating carousel formula CD-ROM jukebox.

Background

With the digitization of information resources and the rapid increase of information volume, the requirements for the storage density, the access rate and the storage life of the memory are continuously increased. Optical storage, which is capable of storing data safely, at low cost, for long periods of time, is becoming increasingly popular. Compared with the expensive price, complex maintenance and high environmental requirement of hard disk storage, the cost of using optical disk storage is lower, and the stored data is safer and more stable. Because the optical disk storage does not need to rotate continuously like a hard disk, the energy consumption is lower, and because the structure of the optical disk determines that the optical disk has longer service life than the hard disk, the optical disk can be used for 50 years or even longer, and does not need to be replaced frequently. With the development of error correction technology, the reliability of data stored in the optical disc is greatly improved. Because the data stored in the optical disc is recorded on the metal film of the disc by the purely physical metal ablation technology, the process is irreversible, so that the data cannot be tampered, and the stability of the data is ensured on the physical level. The hard disk and the magnetic tape become fragile if they are exposed to water or in a humid environment, and the optical disk is not affected by these influences, and data can be normally read even in an office environment at a temperature higher than 35 ℃.

Optical storage, which has such many advantages, is increasingly used in storage. The optical disc library is an optical, mechanical and electronic integrated mass data storage device which takes a standardized optical disc as a data storage medium and is used for storing data information for a long time or permanently, so the optical disc library is widely applied to long-term archiving and storing of data. However, the continuously and rapidly increasing amount of data to be filed puts increasing demands on the optical disc library device, and in order to achieve faster and more data reading and writing, the optical disc library generally adopts a method of stacking and assembling a plurality of optical disc drives into an optical disc drive group, and simultaneously operating the plurality of optical disc drives to read and write data of a plurality of optical discs. Therefore, the optical disk can be read and written more quickly, the optical disk library can be compact in structure and small in overall size due to the fact that the optical disk drives are arranged in a stacking mode. However, while the compact disc library satisfies the functional requirements of the customers, in the compact space of the compact disc library, the optical disc drive can emit a large amount of heat during data recording and data reading, if the heat on the optical disc drive and other devices is not timely removed, the temperature of the optical disc drive and other devices is reduced, the running performance of the equipment cannot be kept in a good state, and even the equipment or the optical disc is damaged due to overhigh temperature. Once the damage accident of the equipment or the optical disc occurs, the data disaster happens, and the immeasurable loss is necessarily caused. These design deficiencies are likely to result in serious, if not insignificant, fruit cachets. Therefore, there is a need for a turntable type optical disc library with reasonable layout, good heat dissipation and long-term operation.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides an easy radiating carousel formula CD-ROM, this carousel formula CD-ROM is rationally distributed, the heat dissipation is good, can keep good operating condition for a long time.

The utility model adopts the technical proposal that:

an easy radiating carousel formula CD storehouse includes: a storage area, a device area, and a control area; the storage area, the device area and the control area are arranged side by side; the storage area is used for storing optical disks and is positioned at one end of the optical disk library; the device area is used for reading and writing the optical disc and is positioned between the storage area and the control area; the control area is used for controlling devices in the device area through commands and is positioned at the other end of the optical disc library; the two sides of the device area, which are not adjacent to the storage area and the control area, are provided with ventilation openings, and a heat dissipation air channel is formed in the device area.

Specifically, the carousel-type optical disc library is divided into three different areas, namely a storage area, a device area and a control area, and each area is responsible for different functions. The storage area is used for storing an optical disc, the device area is used for reading and writing the optical disc through optical storage equipment, and the control area is used for operating the optical storage equipment in the device area through instructions. The optical disk box can obtain better heat dissipation effect through the reasonable layout by dividing the area of the optical disk library. In the conventional optical storage apparatus, the space in the optical disc library is reduced by setting the devices in the optical disc library as compact as possible in consideration of the applicable place, thereby reducing the size of the optical disc library. The problem of insufficient heat dissipation due to the narrow space of the optical disk library is solved by additionally arranging a heat dissipation fan on a cover plate or the front end and the rear end of a shell so as to take away heat. However, if the fan is mounted on the cover plate, the compact structure of the optical disc library cannot be maintained, and the fans are mounted at the front end and the rear end of the box body, the heat of the read/write device cannot be effectively carried away, so that the heat dissipation effect is poor; and because the rotating disc type optical disc library stores the optical disc by the optical disc box, when the optical disc in the box is accessed by the rotation of the optical disc box, the operation of the optical disc box can be influenced by irregular airflow, so that the access process of the optical disc is not stable any more, the accuracy and the safety of optical storage are reduced, and even equipment damage occurs. Therefore, the storage device with low heat productivity and the read-write device with high heat productivity are respectively arranged in two different areas, namely the storage area and the device area, the ventilation opening is arranged on the two sides of the device area, which are not adjacent to the storage area and the control area, and the heat dissipation fan is arranged in the ventilation opening, so that the heat dissipation air channel is formed in the device area to take away the heat. The device with high heat productivity is concentrated at one position, so that the heat can be more conveniently and effectively taken out of the optical disk library, and the storage device in the storage area can be prevented from being directly blown by air flow to influence the access process of the optical disk.

Further, the storage area includes: a turntable type optical disk box, a mechanical arm and a photoelectric sensor; the rotating disc type optical disc box is in a circular ring shape, and a plurality of vertical optical disc storage grooves are radially distributed along the radial circular ring; the manipulator is arranged at the center of a circle of the turntable type optical disc box; the photoelectric sensor is arranged beside the rotating disc type optical disc box and at the upper/lower corner position of one end of the optical disc library.

Specifically, the turntable-type conventional manipulator is generally disposed at one side of the optical disc cartridge, and such a design results in a large space occupied by the manipulator, which results in a considerable increase in the volume of the entire optical storage device. In order to overcome the problem that the mechanical arm occupies a large space, the volume of the optical disk library is further reduced. The scheme adopts the turntable type optical disk box, and the mechanical arm is arranged at the center of the optical disk library, thereby not only reducing the occupied space of the mechanical arm, but also reserving various functions of the optical disk library, and simultaneously ensuring that enough optical disks are used for data storage. The manipulator can still realize various functions of the optical disc library in a limited space. The arrangement can not only quickly and accurately send the optical disk into the optical disk drive, but also improve the response speed and the control precision of the turntable type optical disk library equipment, and simultaneously, the arrangement is convenient to implement and reduces the manufacturing cost of the equipment.

Furthermore, the turntable type disc cartridge comprises a slot disc bracket, an upper slot disc and a lower slot disc; the upper groove plate and the lower groove plate are connected by a groove plate bracket, and the optical disc storage groove of the upper groove plate corresponds to the optical disc storage groove of the lower groove plate.

Specifically, the upper edge of the optical disk is limited by the optical disk storage slot of the upper slot disk of the optical disk case, the lower edge of the optical disk is limited by the optical disk storage slot of the lower slot disk of the optical disk case, and the optical disk storage slots of the upper slot disk and the lower slot disk correspond to each other and act on the same optical disk, so that the optical disk is always kept in a vertical state in the access process. The optical disk can not incline in the process of accessing because of the change of the volume of the optical disk box, thereby avoiding the accident when the mechanical arm operates the optical disk and ensuring the smooth motion of the accessing process. In order to smoothly enter and exit the disc magazine without abrasion of the disc, the width of a disc storage groove on the lower tray is slightly larger than the thickness of the disc, so that the disc cannot be completely and vertically stored on the disc magazine. And, in order to avoid the abrasion of the disc surface, the depth of the disc storage groove is as shallow as possible, which results in a large variation in the tilt angle of the disc. Especially for a large-capacity disc box, the inertia generated by the rotation of the wheel disc is large, so that the disc periodically swings on the disc box, and thus, the side surface of the disc storage groove is greatly stressed, the disc storage groove is quickly fatigue-aged, the service life is greatly reduced, and even mechanical systematic risks can be generated. In addition, only the inclination angle of the optical disc of the lower tray is changed too much, which also increases the alignment difficulty of the optical disc entering the optical drive and the possibility of collision between the optical disc and the optical drive. Although this patent is simple to increase a groove dish structure, the CD receives the restriction of upper and lower CD holding groove, and inclination is restricted in very little angle, and this kind of structure is more favorable to the alignment when the CD gets into or out of the CD driver, and can avoid the produced periodic swing of CD when the CD casket rotates, and the degree of depth of upper and lower CD holding groove can be done more shallowly on the contrary from this, has reduced the possibility to the wearing and tearing of CD data area. The structure is particularly suitable for the large-capacity wheel disc type optical disc box, the number of the optical disc boxes is more and more for the requirements of larger and larger stored data quantity, the structural performance, the stability and the safety performance of the existing optical disc box design can not meet the higher and higher requirements, and the upgrading and updating of the existing product are realized through simple structural transformation from the structural design.

Further, the device region includes: a drive device, an optical drive and a position sensor; the optical driver, the driving device and the position sensor are sequentially arranged beside the turntable type optical disc box; the CD-ROM opening of the CD-ROM faces the CD box and is aligned to the notch of the CD storage groove; the driving device is used for driving the rotating disc type optical disc box to rotate; the position sensor is used for calculating the number of the optical disk storage grooves passed by the rotating rotary disk type optical disk box; the heat dissipation air duct and the ventilation opening are mutually matched, and air flow is formed when the heat dissipation air duct and the ventilation opening work and penetrates through the driving device, the optical drive and the position sensor.

Specifically, air outside the optical disk library is extracted by a heat dissipation fan in a ventilation opening formed in one side of the device area, enters the device area to form an air channel, and flows out from the ventilation opening in the other side. The heat dissipation air duct flows through the optical drive, the driving device and the position sensor to take away heat generated in the operation process.

Further, the control area includes: the control device and the power supply conversion plate are arranged in the electric box body; the control device is used for controlling the storage area and the equipment area; the power supply conversion board is used for providing voltage required by the storage area and device area equipment; and ventilation openings are formed in two sides of the electric box body, which are not adjacent to the device area.

Specifically, devices with high heat generation in the optical disc library are concentrated in the device area, and the heat generated by the control device and the power conversion board is not low in the control area for controlling the devices in the device area. Therefore, ventilation openings are also formed in two sides of the box body of the electric box for bearing the box body and the box body, and heat dissipation fans are also installed in the ventilation openings. Another heat dissipation air duct is formed in the control area to take away heat generated in the operation of the control device and the power supply conversion plate, and the machine can be ensured to keep a good operation state.

Further, the device region further includes: an optical disk protection device; the optical disk protection device is arranged between the turntable type optical disk box and the optical disk drive, and the main body of the optical disk protection device is an arc-shaped guardrail; the arc-shaped guardrail is matched with the outer contour of the turntable type optical disk box, and lifting devices are arranged at two ends of the arc-shaped guardrail, so that the position of an optical disk is limited by the lifting of the guardrail.

Specifically, the arc guardrail in the optical disk protection device is positioned at an initial position when the optical disk box rotates, and blocks the notch of the optical disk storage groove of the groove disk on the optical disk box so as to prevent the optical disk from separating from the optical disk box to cause an accident; when the CD box stops rotating and the notch of the CD storage groove is aligned with the CD driver opening, the lifting devices at the two ends of the arc-shaped guardrail start to operate to lift the arc-shaped guardrail to prevent the arc-shaped guardrail from blocking between the CD box and the CD driver, so that the CD can smoothly enter the CD driver for reading and writing and then returns to the CD box.

Further, comprising: the storage area and the device area are arranged in the shell, and the side walls of the shell positioned at two sides of the device area are provided with ventilation openings; the size of the shell is matched with the sizes of the storage area and the device area, and the side wall of the shell is as close as possible to the in-box device under the condition that the operation of the device is not influenced; the side wall of the shell is provided with a groove matched with the side profile of the turntable type disk box to be installed.

Specifically, in order to make the structure of the optical disc library more compact and make the applicable scenes more, the side wall of the shell is made to be close to the rotating disc type optical disc box as much as possible under the condition that the device in the optical disc library is not influenced to realize the function of reading and writing the optical disc. The design of the groove further makes the structure of the optical disk library more compact, the air channel in the shell is smaller, when the rotating disk type optical disk box rotates, certain air pressure can be formed, and certain cooling effect is formed on the device area.

Furthermore, a plurality of optical drives are arranged beside the turntable type optical disk box in a sector shape.

Specifically, a plurality of optical drives are arranged beside the turntable type optical disc box to realize the simultaneous reading and writing of a plurality of optical discs. The optical drives are distributed in a sector shape, so that the space occupation of the optical disk library by the device is further reduced, and the volume of the optical disk library is reduced.

Furthermore, the plurality of optical drives are of the same optical drive structure and are opposite in installation direction.

Specifically, information data is increased every day, massive data is stored and managed, the capacity of a single-sided optical disk obviously cannot meet the requirement, and in order to realize that a disk box can read and write a double-sided optical disk, the scheme adopts the design of a front-side read-write optical drive and a back-side read-write optical drive. The front read-write optical drive and the back read-write optical drive use the same optical drive, and the optical disk cartridge can read and write a double-sided optical disk by using a turnover installation mode. And different combination modes of the same components can be realized, so that the matching requirements are not required to be considered during production, and only the combination mode and the number are considered. When the device in later stage damages, it is more convenient when maintaining the change, finds the part replacement easily.

Further, the motors used by the manipulator and the driving device are stepping motors.

In particular, the stepping motor is used instead of the conventional replacement servo motor, and the size of the optical disc library is reduced because the stepping motor occupies a much smaller space than a servo motor driver.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the manipulator is arranged at the center of the optical disk library, so that the occupied space of the manipulator is reduced, and various functions of the optical disk library are reserved.

(2) The design of the shell outline makes the structure of the CD box more compact, further reduces the occupied volume of the CD box.

(3) The turntable type optical disk library is divided into different areas, and the high heating devices are concentrated in one area, so that heat dissipation can be performed more effectively and conveniently.

This embodiment provides an easy radiating carousel formula optical disc jukebox, and figure 1 is the utility model discloses an optical disc jukebox top view, as shown in the figure, include: a storage area 1, a device area 2, and a control area 3; the storage area 1, the device area 2 and the control area 3 are arranged side by side; the storage area 1 is used for storing optical discs and is positioned at one end of an optical disc library; the device area 2 is used for reading and writing an optical disc and is positioned between the storage area 1 and the control area 3; the control area 3 is used for controlling devices in the area 2 of the device 31 through commands and is positioned at the other end of the optical disc library; the two sides of the device area 2, which are not adjacent to the storage area 1 and the control area 3, are provided with ventilation openings 13, and a heat dissipation air channel is formed in the device area 2.

Specifically, the carousel-type optical disc library is divided into three different areas, namely a storage area 1, a device area 2 and a control area 3, and each area is responsible for different functions. The storage area 1 is used for storing optical discs, the device area 2 is used for reading and writing optical discs through optical storage equipment, and the control area 3 is used for operating the optical storage equipment of the device area 2 through instructions. The optical disk box can obtain better heat dissipation effect through the reasonable layout by dividing the area of the optical disk library. In the conventional optical storage apparatus, the space in the optical disc library is reduced by setting the devices in the optical disc library as compact as possible in consideration of the applicable place, thereby reducing the size of the optical disc library. The problem of insufficient heat dissipation due to the narrow space of the optical disk library is solved by additionally arranging a heat dissipation fan on a cover plate or the front end and the rear end of a shell so as to take away heat. However, if the fan is mounted on the cover plate, the compact structure of the optical disc library cannot be maintained, and the fans are mounted at the front end and the rear end of the box body, the heat of the read/write device cannot be effectively carried away, so that the heat dissipation effect is poor; and because the rotating disc type optical disc library stores the optical disc by the optical disc box, when the optical disc in the box is accessed by the rotation of the optical disc box, the operation of the optical disc box can be influenced by irregular airflow, so that the access process of the optical disc is not stable any more, the accuracy and the safety of optical storage are reduced, and even equipment damage occurs. Therefore, in the present embodiment, the storage device with low calorific value and the read/write device with high calorific value are respectively disposed in two different areas, namely, the storage area 1 and the device area 2, the ventilation opening 13 is disposed at two sides of the device area 2, which are not adjacent to the storage area 1 and the control area 3, and the ventilation opening 13 has a heat dissipation fan therein, so that a heat dissipation air duct is formed in the device area 2 to take away heat. The device with high heat productivity is concentrated at one position, so that the heat can be more conveniently and effectively taken out of the optical disk library, and the storage device in the storage area 1 can be prevented from being directly blown by air flow to influence the access process of the optical disk.

Further, the storage area 1 includes: a turntable type disc box 4, a mechanical arm 5 and a photoelectric sensor 6; the rotating disc type optical disc box 4 is in a circular ring shape, and a plurality of vertical optical disc storage tanks are radially distributed along the radial circular ring; the manipulator 5 is arranged at the center of the circle of the turntable type disc box 4; the photoelectric sensor 6 is arranged beside the rotating disc type optical disc box 4 and at the upper/lower corner position of one end of the optical disc library.

Specifically, the turntable-type conventional manipulator 5 is generally disposed at one side of the optical disc cartridge, and such a design results in a large space occupied by the manipulator 5, which results in a considerable increase in the volume of the entire optical storage apparatus. In order to overcome the problem that the robot 5 occupies a large space, the volume of the optical disc library is further reduced. In the embodiment, a rotating disc type optical disc cartridge is adopted, and the manipulator 5 is installed at the center of the optical disc library, so that the occupied space of the manipulator 5 is reduced, various functions of the optical disc library are reserved, and meanwhile, enough optical discs are ensured to be used for data storage. The manipulator 5 can still realize various functions of the optical disc library in a limited space. The arrangement can not only quickly and accurately send the optical disk into the optical disk drive 8, but also improve the response speed and the control precision of the turntable type optical disk library equipment, and simultaneously, the arrangement is convenient to implement and reduces the manufacturing cost of the equipment.

Further, fig. 2 is a front view of the carousel-type disc cartridge of the present invention, as shown in the figure, the carousel-type disc cartridge 4 includes a tray support 23, an upper tray 21 and a lower tray 22; the upper tray 21 and the lower tray 22 are connected by a tray support 23, and the disc storage slot of the upper tray 21 corresponds to the disc storage slot of the lower tray 22.

The optical disk cannot incline in the process of accessing because of the change of the volume of the optical disk box, so that accidents caused when the mechanical arm 5 operates the optical disk are avoided, and the smoothness of the motion of the accessing process is ensured. In order to smoothly enter and exit the disc magazine without abrasion of the disc, the width of a disc storage groove on the lower tray is slightly larger than the thickness of the disc, so that the disc cannot be completely and vertically stored on the disc magazine. And, in order to avoid the abrasion of the disc surface, the depth of the disc storage groove is as shallow as possible, which results in a large variation in the tilt angle of the disc. Especially for a large-capacity disc box, the inertia generated by the rotation of the wheel disc is large, so that the disc periodically swings on the disc box, and thus, the side surface of the disc storage groove is greatly stressed, the disc storage groove is quickly fatigue-aged, the service life is greatly reduced, and even mechanical systematic risks can be generated. In addition, only the tilt angle of the optical disc on the lower tray is changed too much, which increases the alignment difficulty of the optical disc entering the optical disc drive 8 and the possibility of collision between the optical disc and the optical disc drive 8. Although this patent is simple to increase a structure of the upper slot disc 21, the compact disc is limited by the upper and lower compact disc storage slots, the inclination angle is limited in a very small angle, this kind of structure is more favorable to the alignment when the compact disc gets into or out of the CD-ROM 8, and can avoid the produced periodic swing of the compact disc when the compact disc casket rotates, therefore the depth of the upper and lower compact disc storage slots can be made shallower on the contrary, has reduced the possibility of the abrasion to the data area of the compact disc.
