Description
Technical Field
The invention relates to the technical field of optical disc storage and pick-and-place equipment, in particular to a cam type optical disc pick-and-place device and a pick-and-place method.
Background
With the further development of the digitization industry, the utilization rate of data storage devices is gradually 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. 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 technology, as a solution for large-scale data storage, has many unique and superior technical characteristics, and has extremely wide application in the fields of data backup, archival storage, secure storage, long-term storage, and the like, compared with magnetic storage technology and semiconductor storage technology. With the advent of the big data age, the rapid expansion of data scale, and the large-scale clustering and distribution of optical storage systems put higher demands on the storage devices of a large number of optical discs:
1. optical disc library data management requiring high density volumes;
2. higher bottom-level intelligent management is required;
3. modularization of the optical disc for storing data is required;
4. the mechanical operation of the equipment is required to be safer, quicker and more concise.
Therefore, the application of discs in large-scale optical disc libraries has been developed from previous individual storage applications of each disc into modular storage applications of several or more than ten discs as an integral unit. The method and the device have the advantages that higher requirements are provided for the grabbing structure of the intelligent mechanical arm which has the functions of batch grabbing, distributing and placing optical disks serving as key components in large data storage equipment, and the working stability, reliability and efficiency of the intelligent mechanical arm are particularly important.
So far, most of the common optical storage devices employ a structure of a disc clamping steel ball (or a steel needle) and an electromagnet. When the guide post is inserted into the central hole of the CD, the electromagnetic coil in the mechanism is powered on, the sliding iron block in the electromagnetic coil moves upwards, the cone moves the steel ball of the CD outwards, and the CD is supported from the central hole to complete the grabbing action. When the electromagnetic coil is powered off, due to the action of gravity, the steel balls (or steel needles) of the clamping disc move inwards, the central hole of the optical disc is separated from the guide post under the action of gravity and is placed at a target position, the optical disc is grabbed by a single optical disc, and when the multi-disc modules need to be distributed and collected in batches, the switching can be completed only by the cooperation of other auxiliary mechanical driving devices.
The above-mentioned grasping method generally has the problem of insufficient reliability, and has influenced the progress and development of the application of the optical storage technology, because of the following reasons: the supporting of the steel balls of the clamping disc on the optical disc only has upward supporting force, and the optical disc can shake when moving rapidly in equipment, so that the reliability of the equipment is affected. And after the equipment runs for a long time, the flexibility of the movement of the steel balls and the conical sliding iron blocks of the clamping disc can be obviously changed under the influence of dust and oxidizing substances, so that the disc taking and placing frequently break down.
In addition, when a plurality of optical disc modules are distributed and collected in batches, extra mechanical action and the matching of a driving device are needed to be completed, and the sensor is needed to be added for assistance, so that complicated uncertain factors are increased, the high-efficiency management of a plurality of optical disc module devices is hindered, and the difficulty is increased for the installation, debugging and maintenance of the devices.
The grabbing structure is a core component of the whole intelligent optical storage device, the reliability of the grabbing structure directly influences the reliability and even the usability of the whole storage device, and when a problem occurs in the disk taking or placing, the equipment stops executing the follow-up action to stop the equipment, or even the damaged data of the optical disk is damaged. Meanwhile, the high efficiency of the grabbing structure directly influences the high efficiency of the data management of the whole equipment, and particularly for a modularized multi-disk mechanism, the hysteresis of action greatly reduces the performance of the whole data management.
Accordingly, the prior art is yet to be improved and developed.
