Description

Push rod structure for optical disk manipulator and optical disk box

Technical Field

The utility model relates to an optical storage device technical field, more specifically relates to a push rod structure and CD casket for CD manipulator.

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 existing optical disc libraries of various types have defects. In the existing optical disc library products, a mechanical arm is generally installed at one side of the optical disc library, and an optical disc in a disc cartridge in the optical disc library is taken out by the action of the mechanical arm and then put into an optical drive for reading and writing operations. Although the design of installing the manipulator on one side of the optical disc library realizes the expected functions of the optical disc library product, the manipulator needs to occupy a small space due to the action requirement of the manipulator. The manipulator installed at one side of the optical disc library occupies a large space, which results in an increase in the volume of the entire optical storage device and a limitation in applicable places. The operation of the robot is then relatively complex, making the optical storage less accurate and safe. With the development of society, information data is increasing every day, optical storage devices are also rapidly advancing, and the existing manipulator can not meet the requirements of the optical storage devices. Therefore, there is a need for an improved optical disc handling apparatus, which occupies a smaller space and can access an optical disc accurately and reliably.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a push rod structure for CD manipulator makes CD manipulator occupation space littleer, and the access CD is more accurate reliable.

Specifically, the guide rail is horizontally fixed in the support frame, a slide block is arranged in the guide rail, a driving mechanism positioned at one end of the guide rail is used for driving the slide block to move back and forth in the guide rail, and when the slide block moves, a push rod connected with the slide block also moves along with the slide block. When the moving distance of the push rod reaches a certain length, the front end of the push rod extends into the optical disk library to push the optical disk.

Further, one end of the push rod is used for being driven by the driving mechanism, and the other end of the push rod is provided with a notch matched with the edge of the optical disk.

Specifically, the push rod is linear, when the pushed optical disc is in contact with the front end of the push rod, the linear push rod provides thrust for the optical disc, the edge of the optical disc enters the vertical notch of the push rod, and in the moving process of the pushed optical disc, the notch always applies force to two side faces of the push optical disc to enable the push optical disc to keep a basically vertical direction. This facilitates alignment of the optical disc in and out of the read/write apparatus, reduces the tilt of the optical disc, and reduces the probability of collision between the optical disc and the device.

Furthermore, the cross section of the notch is isosceles trapezoid, the opening end at the front end is a trapezoid long bottom, the bottom of the notch is a trapezoid short bottom, the height of the trapezoid is 0.5-1.5mm, and the included angle between the trapezoid waist and the long bottom is 65-80 degrees.

The light emitter can emit infrared light or visible light, and the light receiver can receive light under the unobstructed condition. When the induction sheet moves a certain distance along with the sliding block, the induction sheet passes through the sensor and blocks between the light emitter and the receiver, so that the receiver cannot receive the light signal emitted by the light emitter, and the photoelectric sensor outputs a control signal.

Further, comprising: the laser sensor is arranged on the support frame; the direction of the laser sensor projected light and the push direction of the push rod are on the same vertical plane.

Specifically, the laser sensor is located on the support frame, the light projection direction and the push direction of the push rod are located on the same vertical plane, and the laser sensor is used for detecting whether an optical disc exists in an optical disc slot in the optical disc box or not, if yes, pushing operation is carried out according to signals, and if not, signals without the optical disc are fed back. The laser sensor is arranged on the support frame to prevent the manipulator from performing idle pushing operation, so that the manipulator is protected and more durable; and redundant operations in the optical disc access are reduced, and the reliability and the accuracy of optical storage are improved.

In particular, the existing mechanical arm is generally disposed at one side of the optical disc cartridge, and such a design results in a large space occupied by the mechanical arm, which results in a considerable increase in the volume of the entire optical storage device. In order to overcome the problem of large occupied space of the manipulator, the scheme adopts the rotating disc type optical disc box, and the manipulator is arranged at the center of the optical disc library, so that the occupied space of the manipulator 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 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.

Further, the robot further includes: the laser sensor is arranged on the support frame; the direction of the light projected by the laser sensor and the pushing direction of the push rod are on the same vertical plane; the direction of the projected light is in the disc storage slot of the disc cartridge.

Further, still include: the optical disk cartridge driving mechanism is a stepping motor.

Specifically, the driving mechanism of the optical disc cartridge is different from the existing optical disc library product, and a stepping motor is used instead of a servo motor.
