The cleaning method comprises the following steps: (1) an optical module is moved to the preset interpretation region on the cleaning surface by a radial transferring device, and an optical lens is focused on the interpretation region by a focus actuating device; (2) if the optical lens is incapable of being focused on the interpretation region, the cleaning disc is rotated by a motor, and the optical lens is acted with the cleaning device on the cleaning surface to clean the optical lens by making use of the radial transferring device and the focus actuating device.
Description
The present invention relates to a kind of clean method of optical disk system, especially a kind of clean method that utilizes a cleaning disc to clean the optical lens of an optical disk system.
In the working environment of today, discs has been used widely on the storage lot of data.During data on reading a slice discs, the one side of store data can be placed in the optical disk system down on the discs, and the optical lens of optical disk system then can upwards focus on to read the data on the discs discs.Because the operating environment of optical disk system is not a confined space, therefore through after using for a long time, dust and impurity can build up the surface of optical lens and its optically read ability is affected.In order to clean the laying dust of optical lens, more existing on the market utilization cleaning discs clean the commodity of optical lens.
Please refer to Fig. 1.Fig. 1 shows the cleaning face 12 of an existing cleaning disc 10, and the hairbrush 14 which is provided with a projection is used for the optical lens of clear light disc system.On the cleaning face 12 except hairbrush 14, other parts can as general optical disk be used for the emitted laser beam of reflection optical lens so that optical lens focused on.After the user will clean disc 10 and put into a traditional optical disk system, the track that optical disk system can be earlier moves on to the inner ring of cleaning face 12 with its optical lens down and begin to utilize laser beam to come this place is focused on distance with 12 in adjustment optical lens and cleaning face.After focusing on, optical disk system can outwards move optical lens with the data on the academic probation cleaning face 12.In the process that moves, optical lens can utilize at any time that institute's laser light reflected light focuses on the cleaning face 12, and the action of this focusing can approximately maintain some fixing focusing distances with the distance of 12 in optical lens and cleaning face.When optical lens moved past cleaning orbital 16, hairbrush 14 was because its length above focusing distance, therefore will touch the surface of optical lens and the laying dust on camera lens surface is removed.
The problem of this clean method is, when optical lens by hairbrush 14 time, because therefore hairbrush 14 reflector laser light suitably can make optical lens focus on.This situation that can't focus on makes optical disk system be seen as academic probation failure and optical lens is descended at once and regains through regular meeting; the action of this decline makes optical lens maintain focusing distance with cleaning face 12, so hairbrush 14 also just can not clean the surface of optical lens again.In this case, if the user wish can with the camera lens cleaning surfaces more totally, just must be once more or repeatedly will clean disc 10 and take out optical disk systems and then put into optical disk system so that the academic probation that optical disk system can repeat is cleaned the cleaning face 12 of disc 10 with the generation cleaning effect.This program is very inconvenient to the user.
Except cleaning disc 10, other different cleaning disc is also arranged on the market, for example hairbrush is to be spot distribution rather than is to be line style to distribute as hairbrush 14, but their employed cleaning procedures are all the same with cleaning disc 10 with the shortcoming that is produced, just when optical lens because of can't focus on the time by hairbrush, the reaction of optical lens can make hairbrush can't produce cleaning action again, so the user often must repeatedly repeat this cleaning procedure and could effectively optical lens be cleaned out.
Therefore, one object of the present invention is to provide a kind of clean method that utilizes a new-type cleaning disc to clean the optical lens of an optical disk system, to reach better cleaning effect.
Another object of the present invention is to provide a kind of and utilize existing cleaning disc to clean the clean method of an optical disk system optical lens, to solve the problem that above-mentioned existing method is run into.
