Abstract
This invention concerns apparatus for protecting and/or repairing damage to an optical surface, the apparatus comprising a film-like member having a protective film (1) provided with a resiliently conformable and tacky optical coupling medium (2) adapted for adhesive retention to said surface.
Description
The present invention relates to protect and/or repair the device of optical component surface damage, relate in particular to this device of laminated film component form.
Many optical device contain the surface, and its consistance depends on the calibration function of device.For example, camera lens, true mirror, optical memory device etc. if the optical surface of these devices sustains damage, for example are scratched, and so, the calibration function of device can affect adversely.
With optical memory device (OSD) is example, and these devices generally include discoidal transparency carrier, is loaded with optical recording data on it, and expectation is inquired these devices photographically so that the data of recovery record on these substrates.The example of these devices has the optical recording disk of (nonrestrictive) such as CD (CD).
OSD such as CD is normally durable, but responsive to small scratch and other surface damage, these damages surpass the typical sizes of the data character string of record dimensionally easily.Certainly, there are some quite complicated error recovery routines, can be encased in hope from the electronic system of most unit of this device playback and/or reproducing recorded data, but, this system limited in one's ability, they can be damaged institute and defeat, and damage is widely and/or has certain type.For example, on CD, much more serious than passing orbital drive usually to the similar extensive injuries of walking along the damage of the arc walking of track record.Therefore; need provide a kind of and can be applied to the film shape member that new OSD upward protects its surface to avoid damaging; if and/or it is applied on the surface of the OSD that has sustained damage; it can reduce the adverse effect of this damage at least; because when by optical challenge when OSD carries out playback, this damage can influence the integrality of data.
My BrP GB-B-2279799 describes and a kind of like this film shape member of opinion; wherein a kind of fluid media (medium) is set being inquired between the surface of plastic protective film and OSC; arrangement is such; plastic sheeting has the refractive index that approaches the OSD substrate; perhaps be a part of substrate at least; wish by inquiry by it, for example read means retrieval optical recording data by laser.Fluid media (medium) has similar refractive index, and plays effective optical coupler, and it flow in the surface topography of substrate of OSD, therefore can fill scratch and other defective in the surface.The cohesion that exists in the fluid media (medium) allows to be diffused in the film between plastic sheeting and the OSD, and thus, because capillary result, OSD can stop that plastic sheeting separates with OSD on the direction of vertical plastic film surface.If necessary, can apply another layer film on the opposite one side of OSD,, can be easily double-layer films be locked on the spot in their edges by public organizations if adopt edge locked mechanism.Yet, because fluid media (medium) is as the optical coupler between plastic sheeting and the OSD, this coupling mechanism can trend towards going to the periphery of CD during use under centripetal force/action of centrifugal force, final scatter from the CD edge or produce variable influence at the surf zone of OSD at least.Obviously this is undesirable.
My International Patent Application WO 96/21928 is provided by a kind of system of the OSD of providing shell, has the purpose that is similar to above-mentioned BrP, still, can replace the fluid optical coupler with the malleable solid material that can spread in the surface imperfection here.Shell is made up of the collaborative work of suitable setting and the parts of coupling, because other means that OSD and film shape member are kept together may be not enough, promptly promoted by the high shear force that can produce between the operating period at OSD, cohesion in the solid ductility coupling mechanism and static " are close to film " type power are failed give enough prevention with the horizontal slip between the OSD with separating to film shape member, therefore need shell.Produce so high shearing force, for example on CD, in use under the high speed of the state of reading that drops on the CD with respect to laser beam to be limited, make its rotation.Yet, use whole casing to protect OSD can bring shortcoming, lacking the space is a problem, and/or the manufacturing cost problem.
The objective of the invention is to overcome the shortcoming of above these arrangements.
According to an aspect of the present invention; a kind of protection is provided and/or repairs the device that optical surface is damaged; described device comprises film shape member, has to be provided with to be suitable for the bonding protective film that remains on described lip-deep rebound resilience applying and bonding optical coupled medium.
In this respect, be understood that inherent viscosity of couplant causes bonding remaining on the optical surface just.
The bonding agent viscosity of couplant has strengthened significantly to the shearing force repellence, and shearing force can cause that film shape member laterally slides with respect to described device surface.So far, with the reason of discussing, consider the desirable characteristics of film shape member for following, especially at the optimization of its refractive index and to the requirement of the conformal ability of optical coupled medium, produce a very large impact for using film shape member bonding agent viscosity to remain on the OSD.The present invention allows the arrangement that realizes that this is favourable.
In this respect, the viscosity of optical coupled medium preferably is enough to resist the separation of couplant, thereby opposing in normal working conditions, and film shape member is from the separation of optical surface, if and necessary or need, allow the manual film shape member of removing from the surface.During from optical surface removing films shape member, the optical coupled medium is taken off with preferably being cleaned, and does not stay residue, just can apply new film shape member so that need not do cleaning to optical surface.
The viscosity of couplant preferably is enough to overcome the inside screen resilience of couplant further, and this will pull out couplant from any surface imperfection of optical surface.
Can provide optical surface, as the part of optical memory device (OSD).Therefore in this case, the optical coupled medium preferably has enough viscosity, to avoid allowing the manual film shape member of removing simultaneously in the horizontal slip of film shape member during the normal OSD of use from the OSD.
Usually, although optional, described surface will be a kind of like this surface, by it or from it, can derive the contained information that has of device by optical challenge.Therefore, preferably by the material of optics GTG, for example polycarbonate forms film shape member.Yet, can adopt any other suitable material, comprise the cellophane of optics GTG.
According to another aspect of the present invention, provide a kind of protection and/revise method to the optical component surface damage, said method comprising the steps of:
(a) provide a kind of protective film;
(b) provide the protective film with optical coupled medium, to form film shape member, described optical coupled medium comprises the conformal and cohesive material of rebound resilience; With
(c) by described optical coupled medium film shape member is adhesively secured on the described surface.
Optical coupled medium and protective film can be other elements of branch, by reverse intaglio printing technological process for coating the optical coupled medium are applied on the film, form film shape member.On the other hand, two surface cures of the material by will making film shape member are in various degree, thereby a tacky surfaces and a non-sticky surface are provided, and optical coupled medium and film are integrally formed.
The device that provides with sheet form according to the above also is provided in the present invention, the OSD that produces by said method, and/or aforesaid device organized in first state of the present invention.The present invention further comprises the optical coupled medium for this device or the use of this method.
In order more to be expressly understood the present invention and to be convenient to realize the present invention, below will be by taking a single example and describing certain embodiments with reference to the accompanying drawings, wherein:
Fig. 1 illustrates the film shape member of the example according to the present invention with planimetric map, is attached with the protection part that is easy to open on it.
Fig. 2 illustrates the sectional view (not to scale (NTS)) of film shape member, has protection part as shown in Figure 1.
Before in detail with reference to the accompanying drawings, provide earlier general description of the present invention.
Therefore, for simple and avoid for the purpose of the unsuitable repetition, being referenced as that the present invention did is applied to CD.Yet as having described the front, the present invention can be applied to any member with surface, and its optical characteristics has critical function, for example data scanning instrument, lens, catoptron, duplicating machine etc.One of skill in the art will be appreciated that, produces the film shape member that is suitable for these other application, need do the improvement on the details.
So; for being applied to CD; the invention provides a kind of flat annulus film shape member (comprising that optical characteristics is similar to the protective film of the optical characteristics of CD itself and the conformal viscosity optical coupled of rebound resilience medium), inquired by laser beam or the surface of " reading " is designed for the expection of protecting OSD at least.The present invention also provides the subsidiary function of reparation to the little damage in above-mentioned surface valuably, allows the conformal viscosity optical coupled of rebound resilience medium to extend in the middle of the scratch etc.
The advantage that the optical coupled medium is set is, when laser beam its strength degradation at least 5% during by any surface, " loss " of light intensity be by light surfacewise by level scatter cause.Do not had the CD of optical coupled medium or the place that other optical surface provides protecting component, on its each path by protecting component and optical surface (having three effective surfaces that light passes through), light intensity will descend at least 15%.Therefore, when reading CD, in the laser beam of CD Player and search on the path between the device, intensity of laser beam will reduce at least 30%.This does not consider other light intensity decays effect.Yet, in the CD technology, when light passes through optic disc base board, because absorbing light intensity further reduces.Really, direct some number percents of light further loss by CD silver oxide coating are to this coating attenuate progressively, to reduce manufacturing cost.Adopt term " reflectivity " as dropping on measuring of CD glazing intensity percent decline in the prior art.As an example, do not protect the maximum reflectivity of tectal CD to be about 90% (light intensity reduces by 5% when entering CD, reduces by 5% when leaving CD).
The I of appropriate CD operation is accepted reflectivity and is thought approximately 70%, and being understood that between the surface of film shape protection member and CD does not have the optical coupled medium, along these surperficial chromatic dispersions, has same problem with reduction light in light is searched.
The optical coupled medium of film shape member is the protected surface on the two that is fixed to protective film and CD by its viscosity, has enough intensity is drawn back film shape member from CD with the meeting of opposing effect during CD disposes and plays power.Specifically, not only act on the peeling force on the direction that is basically perpendicular to protected surface, and the shearing force that acts in the plane on protected surface is blocked all, need not device is done further clamping or encapsulation.
Yet the viscosity of optical coupled medium allows film shape member to be removed, and replaces if desired, can peel off the optical coupled medium from CD.Preferably, mode goes up stripping film shape member from CD by hand, the residue that can not damage CD and can on CD, not stay any optical coupled medium, thus new film shape member can be applied on the CD, not as cleaning.
The refractive index of optical coupled medium can with the refractive index of the transparency carrier of CD reasonably closely coupling (at least within 20%, be preferably within 10%, ideally within 5%), when the data of retrieve stored on CD, the inquiry laser beam is passed through optic disc base board.Typically, CD adopts polycarbonate substrate, and its refractive index is about 1.5, and the suitable candidate of optical coupled medium adopts the compound that has based on silicone in these situations.In addition, use for CD, the optical coupled medium should have the birefringence less than 100nm.
Yet, exist tangible obstacle to have influence on and use this compound to make this purposes.Recall; the optical coupled medium preferably can be filled scratch etc.; go up and repair its little damage so that fit to the surface; the important bonding maintenance of protective film to protected surface is provided; notice immediately; previously known silicone compounds does not represent bond property usually, and on the contrary, they are often used as the mould remover and carry out other anti-stick subsides function.
Yet the inventor has designed the following process that really silicone-based compounds is used with the object of the invention.
At first, use catalyzer in the mode of the whole curing that prevents silicone compounds.Under partly solidified condition, rebound resilience and the cohesive of compound exhibits to substrate used herein and membraneous material are provided.
In an example, silica-based product DC781 (Dow Corning) is mixed mutually with 20% silicone fluid of viscosity higher level, silica-based product is the transparent elastic body that contains acetate silane, at room temperature solidifies about 1 hour.This prevents DC781 product full solidification, but so its keep to be bonding and resilience.Yet, accelerating to several seconds magnitude in order to make the partly solidified time, this is the advantage of commercial product, people can make silicone product dilution with a large amount of solvents, and this is not preferable process, mainly due to environment reason.
In better embodiment, for example be used for optical memory device with the CD form, the optical coupled medium comprises:
A) vast scale of following material (maximum by weight constitutes):
1) silicon dielectric gel (refractive index 1.4074), transparent low viscosity silicone balloon.This gel is designed to form damping, closes up certainly, the rebound resilience quality; Or
2) based on the silicone elastomer (glycidoxypropyltrime,hoxysilane, refractive index 1.428) of glycidoxy and trimethoxy silane organic group.This is quick-setting silicone elastomer, and it is inserted in the conformal coating; Or
3) silicone polymer is blended in (refractive index is about 1.5) in the hydrocarbon solvent; And
B) small scale of silicone fluid, this is transparent colourless liquid, and is almost tasteless, preferably viscosity is between 0 to 2000 η.The refractive index of this fluid is about 1.5, and is relevant with viscosity.Use the overall cohesive of the silicone fluid increase optical coupled medium of small scale.The minimizing of catalyst elements (referring to following content) will cause contacting the raising of bonding quality.
Form more specifically and comprise the Silcolease 426 (Rhone PoulencChemicals) of 15 parts by weight (" pbw "), two kinds of rapid-action catalyzer, be Catalyst 62a and Catalyst 62b (RhonePoulenc Chemicals), each is the mixing of the silicone oil Flll-10000 (have the high viscosity ratings, provided by Ambersil company limited) of the Toluene (a kind of solvents for commercial commonly used) of 0.75pbw, 40pbw and 5pbw.This potpourri produces the optical coupled medium with appropriate refractive index (1.55) that a kind of confession is used based on the OSD of polycarbonate, and it has shown other key property discussed above.
Concrete composition in addition is:
(A) silicone oil (Dow Corning) of the Sylgard 527A of 40pbw and B silicone dielectric gel (Dow Corning), 10pbw and the toluene of 20pbw.The refractive index that this composition shows is about 1.4.
(B) toluene of the silicone oil of the DC781 of 40pbw, 10pbw and 30pbw.
The two is based on silicone elastomer DC 781 and Sylgard 527, on the surface topography of the OSD of the to be repaired/protection of using elastic body to allow couplant to fit to well in the optical coupled medium.It will be noted that couplant is a rebound resilience/flexible, so can extend in the scratch rather than flow into and spread in them.Therefore, the viscosity of couplant preferably should be enough strong, with the propensity that stops the couplant material to be pulled out from scratch.
Further form and comprise Rhone Poulenc product, be called Poly200.This is a kind of epoxy resin silicone of UV curable.Ultra-violet curing has certain advantage, and it does not need heating to be cured, and has therefore avoided and may especially increase its fragility to the damage of protective film.In addition, ultra-violet curing can make production run more cheap and quicker, does not comprise solvent, and is therefore favourable to environment.The normal composition of this product is 100 umber polymkeric substance to 2.5 umber catalyzer.The optical coupled medium reduces about 10% and increase by 1 umber silicone fluid and form by making catalyzer.
Although above promotion is used and is made the optical coupled medium based on the material of silicone, but the present invention also not exclusively estimates according to this use, for example, can adopt contact adhesive to replace, as long as their refractive index is suitable and is consistent on surf zone.
In another embodiment, film shape member and optical coupled medium are integrally formed.In this respect, device can be taked to have appropriate refractive index and have form less than the optical thin film of 100nm birefringence level for surface to be adhered to.Film can utilize the liquid compound with described characteristic to make, and is partly solidified to simultaneously carrying out, and another side is carried out full solidification.This will cause having the film of viscosity optical coupled dielectric surface on one side, another side is cured as inviscid, and necessary protecting component is provided.Can adopt the ultraviolet sensitivity catalyzer to make this purposes, the one side with film is exposed to ultraviolet light here, will cause this face full solidification and another side will keep semi-solid preparation and viscosity.
Now will specifically describe with reference to the accompanying drawings.
Expediently,, make optical coupled medium, the protective film with optical coupled medium 2 is provided, typically be the polycarbonate film 1 (being used for the CD protection) of 125 microns of thickness with 6 micron thickness of every square metre 6 gram by means of reverse photogravure roller.Certainly, this size can change to be fit to wish to produce the application of film shape member.Particularly, the weight of couplant can be different from weight cited above, is noted that its weight is heavy more usually, and the optical coupled medium is easy more to be fitted on the protected surface.The process that applies couplant in the room of cleaning is preferable to be reduced in the risk that occurs impurity or other undesirable snotter in the optical coupled medium, in case be cured, it must be level and smooth as far as possible.
For transmitting and storage, can be easily film shape member be joined in " sandwich " structure between the cheap protective film with remover.For this reason, in whole process of production, arrange as follows:
Give the polyester of 100 micron thickness or film 3 coatings thin (for example 2 microns) and the low-down contact adhesive of levels of viscosity of similar cheap material.With bonding agent this material is folded on the transparent polycarbonate film 1 (two sides is level and smooth) then, constitutes the protective film element of film member 1,2, therefore have as 125 microns of previous described thickness.On the one or both sides of polycarbonate film smooth surface, begin to provide the protection mask; If provide, remove the mask on the one side, allowing to apply mylar 3, so its constitutes carrier band.
The mask (if providing) that gathers on another smooth surface that plays acid esters film 1 is provided then, the optical coupled medium 2 of 6 microns of applied thickness thereon, preferably in clean room, carry out as mentioned above, therefore, form the viscosity of film shape member 1,2 and the optical coupled medium of applying.Apply the protection release liner 4 that thickness is about 36 microns to medium then, keep its smooth finish and globality.Be understood that release liner can be any also can not making enough smoothly so that the optical coupled medium can not begin to fit to the material that makes things convenient on it with the silicone reaction.Yet release liner is generally polyester.
Then, " the sandwich material " that the annular cutting so constitutes produces and is applied to the suitable shape of CD and the medium of size.For this reason, from above material cutting release liner 4, optical coupled medium 2 and polycarbonate film 1, produce internal diameter 42mm, external diameter 120mm with blade.On the outer rim of release liner 4, form and peel off outshot 5, be convenient to the final user and remove it.
From below cutting polyester support band 3, to internal diameter 15mm and same outer diameter as 120mm+/-, the same with other element.Critically carry out such cutting, identical with the annular cutting center of being done by element 1,2 and 4, on the outer rim of carrier band 3, form a pair of outshot 6,7 of peeling off, each other in the relative both sides of diameter, help the final user to remove.
The final user puts on film shape member on the CD in the following manner.
OSD should clean, and will be recorded a side (blank and light) then and be placed in the normal CD storage box (being commonly referred to " jewel " case).Remove release liners 4 from the optical coupled medium 2 of film shape member 1,2 then, peel off outshot 6,7, avoid contacting with the surface of optical coupled medium by utilizing peel off on outshot 5 and the polyester support band 3 two on the antiseize membrane 4.Place film shape member 1,2 then, optical coupled medium one side direction is transferred on the CD,, utilize the centrally-pivoted axle in the jewel case to make film shape member be positioned at central authorities, be centered close in the cutting hole in the carrier band 3 by the co-operating of its 15mm.In case film shape member is suitably placed on the CD on the spot, utilize once more last form peel off outshot 6,7, remove polyester support band 3, check film shape member 1,2 then, appropriately in place.By applying radially downward pressure gently, squeeze any visible bubble between film shape member and the CD with thumb.If necessary, can carry out cleaning to the top surface of the protecting component 1 of film shape member, CD prepares to play then.
Should be understood that shown embodiment shows that the present invention is applied in the illustrated purposes with a definite form.In fact, the present invention can be applied in many different structures, and detailed embodiment directly allows one of skill in the art realize.For example, as required, can change the size of different parts.In addition, though film shape member is preferably formed by the plastic material such as polycarbonate, can adopt any suitable equivalent material.
