Abstract

The invention aims to provide a simple and cost-effective method for coating an optically readable data carrier. The invention is characterised in that a transparent adhesive film which has adhesive on one side is applied onto a data carrier surface to be protected. A transparent protective layer is subsequently applied to the optically readable data carrier. Said protective layer also has an adhesive film with adhesive on one side.

Description

The plater of optically readable data carrier and method
The present invention relates to a kind of plater and a kind of coating process of optically readable data carrier, also relate to a kind of optically readable data carrier.
Optical data carrier such as CD, and manufacturing method and apparatus is extensively known in the prior art.This data carrier has the surface of record data usually, and this surface must be protected not affected by environment.In order to protect this surface, adopt a kind of lacquer of age hardening in the past, this lacquer is coated in the centre of the data carrier of high speed rotating, so that outwards flow by centrifugal force, thereby forms basic one deck uniformly on CD.But the necessary high speed rotating of data carrier is evenly distributed on the surface to be protected lacquer to produce enough centrifugal force here.There is the danger of corrupt data carrier in this process.In addition, lacquer unnecessary in this method breaks away from data carrier, must difficultly remove afterwards.
Can learn that from EP-A-0 855 703 a kind of is the method that two essentially identical disc-shaped data carriers substrates are stained with the adhesive film of one deck biadhesive.
Method is set out thus, and the technical problem to be solved in the present invention is a kind of optically readable data carrier coating process of simple economy to be provided and a kind of data carrier that produces like this is provided.
According to the present invention, this task is to be coated onto on the data carrier surface to be protected by the transparent adhesive film with a kind of single face viscosity to realize in a kind of coating process of optically readable data carrier.Adopt a kind of advantage of adhesive film to be, saved above-mentioned for the data carrier japanning centrifugal process and do not produce must hard disengaging of removing the residue lacquer.Adhesive film also provides a kind of solution of the simple economy for the data carrier coating in addition.
According to a kind of preferred implementing form of the present invention, adhesive film breaks away from from a carrier thin film in being coated onto the data carrier process or afterwards.This carrier thin film has an advantage, that is, film was protected and made adhesive film to have enough transportation stability before being coated onto on the data carrier.In addition, be preferably in adhesive film and layer protecting film removed from adhesive film before being coated onto on the data carrier, this diaphragm protect the not contaminated and damage of the single face tacky surfaces of adhesive film before coating procedure.
Advantageously, the shape of adhesive film and size are suitable with the surface to be protected of data carrier, so that cover fully.Here, preferably determine shape and sizable adhesive film part with data carrier in the carrier thin film upper punch.
Adhesive film preferably centrally is coated onto on the surface to be protected of data carrier, to guarantee data carrier all sites uniform coating.For this reason, adhesive film and data carrier are alignd before being preferably in coating mutually.
In another kind of form of implementation of the present invention, adhesive film hold-down roller by a rotation in coating procedure is pressed onto on the data carrier, and the hold-down roller of this rotation guarantees contact reliably between adhesive film and data carrier.This moment, the snap-in force of hold-down roller preferably can be controlled, so that realize the optimum adhesion effect on the data carrier surface.
Adhesive film is preferably in by hold-down roller and is under the angle of a regulation with regard to the relative data carrier surface before compressing, and keeps at a certain distance away to keep adhesive film and data carrier, and guarantees that control compresses at the hold-down roller position.Be implemented in thus and avoid containing air bubble between adhesive film and the data carrier.
According to a kind of preferred implementing form of the present invention, data carrier and hold-down roller relative motion can constantly be coated onto on the data carrier surface adhesive film.This moment, data carrier preferably moved through hold-down roller linearly, and hold-down roller is best and the motion of data carrier keeps synchronously adhesive film being pressed onto on the data carrier continuously.
According to a kind of form of implementation of the present invention, adhesive film on being coated onto optical data carrier after sclerosis, improve intensity, thereby protect optical data carrier better.This moment, adhesive film was preferably by thermal treatment and/or pressure and/or time sclerosis.In another kind of form of implementation of the present invention, adhesive film preferably passes through ultraviolet radiation hardened.
Preferably the especially so-called PC band of transparent protective seam is coated onto adhesive film not with the bonding side of data carrier on.
The technical matters that the present invention proposes also solves by the plater of an optically readable data carrier, and this device has a gummed platform, and the transparent adhesive film of single face viscosity is coated onto on the surface to be protected of data carrier.The described advantage of method above in this device, having obtained.Especially in this device, cancelled because centrifugal process causes the danger of corrupt data carrier, saved hard processing and removing in addition the residue lacquer that breaks away from.
In addition, task of the present invention realizes by a kind of optically readable data carrier that has protective clear layer that also wherein protective seam is a kind of adhesive film of single face viscosity.The advantage of having stated above the transparent adhesive film of employing single face viscosity has as protective seam.According to this preferred implementing form of the present invention, data carrier is arranged in the protection housing around data carrier.By using a protection housing can obviously reduce requirement,, prevent to be polluted and chemical affect but mainly be used as protective seam because this protective seam need not bear stronger load to protective seam.
Further describe the present invention by preferred embodiment with reference to accompanying drawing below.Be illustrated as:

Fig. 3 is according to the side view of the another kind of form of implementation of gummed platform of the present invention;
The diagrammatic side view of the another kind of adhesive film of Fig. 4.
Fig. 1 shows the device 1 that is used to make the optical data carrier that has at least one surface to be protected.
This device has an input block 3 and is used to import optical data carrier such as CD or DVR.Data carrier 6 is transported to a gummed platform 7 from first input block 3, and this gummed platform illustrates in greater detail in Fig. 2 and 3.In this gummed platform, the pressure sensitive adhesive tape of a single face viscosity that is known as PSA band or the surface to be protected that adhesive film is coated onto optical data carrier 6.Here adhesive tape or adhesive film be interpreted as with glue make not with one deck of carrier material.The optical property of glue-line usually can more accurate control better than the performance of coated carrier material.Adhesive film has different cohesives according to institute's applied pressure above it.Data carrier is put into one and has centering and close on the round platform 8 of clamping device then.
Then round platform continues rotation, places a treatment bench 11 up to it, is positioned at the adhesive film sclerosis on the data carrier in this treatment bench.Round platform forwards a unloading position to then, and is removed at this position optical data carrier.
Device 1 is arranged in the pure space, and each operation all can be carried out under the pure space condition.
Fig. 2 and 3 shows the synoptic diagram according to a gummed platform 7 of the present invention, and wherein the layout of gummed platform 7 each parts shown in Fig. 2 and 3 is different.But in the description according to Fig. 2 and 3 pairs of gummed platforms, same Reference numeral is represented identical or similar parts below.
Gummed platform 7 has an input roller 22, is wound with banded gummed film 23 on this input roller.Gummed film 23 has three kinds of films, i.e. the adhesive film 25 of diaphragm 24, single face viscosity and carrier thin film 26 are shown in the round section of the amplification among Fig. 2 is clear.Adhesive film 25 has a part 27 that goes out according to the surface size to be protected and the shape stamping-out of data carrier 6.
The gummed platform also has one to receive roller 28, receives remaining gummed film 23 after the primary gluing process.Gummed film 23 is around a plurality of rollers 30 to 38 guiding, to provide definite motion path of banded gummed film 23 between roller 22 and 28 between input roller 22 and reception roller 28.Each roller 30 to 38 all can be around its rotating shaft rotation separately, and roller 31 and 37 is designed to so-called dancer roll (T  nzerrollen), and it movably is supported in the horizontal direction, so that can make gummed film 23 obtain length compensation between roller 22 and 28.Although the gummed circulation is discontinuous thus, roller 22 and 28 still can rotate with constant speed, and is as described below.The unnecessary portions of adhesive film 25 can be in advance just before the gummed film enters the gummed platform, for example when making the gummed film, be removed, perhaps can stay on the film, with guarantee film 23 on its whole width and length at least before the primary gluing process thickness even.
Gummed film 23 at these scraper place gummed film 23 zig zags, so that diaphragm 24 can be peeled from gummed film 23, thereby comes out so that bonding with optical data carrier a side of the viscosity of adhesive film 25 around scraper 40 guiding of a wedge shape.Can be clear that in Fig. 3 diaphragm 24 peels.Diaphragm 24 peels afterwards around to a unshowned roller.Also can be without the wedge shape scraper, and with the film peeling apparatus of another kind of form.
Gummed film 23 is after scraper 40 guiding, and around lower roller 33 guiding, this roller 33 is designed to hold-down roller from the horizontal by certain angle.After roller 33, gummed film 23 is around axle 34 guiding, and this axle drives by a motor 42.
The rotation of driven roller 34 at this moment makes the roller that the is designed to pure guide roller 35 corresponding rotations of hold-down roller 33 and back.
Gummed platform 7 has a first sensor 45, and it combines and be used for surveying the profile of the part that is punched out 27 of adhesive film 25 with driven roller 34.Gummed film 23 longitudinally moves around by driven roller 34, identifies up to sensor 45 and is punched part 27 fixed wheel exterior feature really, for example an interstitial hole that is punched out.When sensor 45 identified interstitial hole, its motion by film directly was positioned at a seamed edge top of interstitial hole, make thus part 27 opposed rollers 34 especially hold-down roller 33 along the vertically accurately alignment of gummed films 23.
Gummed platform 7 also has a supporting delivery unit 47 to be used to data carrier to be glued together 6.Supporting delivery unit 47 has constituted the horizontal supporting of data carrier 6 and can move in all directions by suitable telecontrol equipment not shown further.By one can be buried alignment pin 48 guarantee the data carriers 6 accurate alignment of supporting delivery units 47 relatively.Pin 47 can be buried in the gummed process, so that can not be damaged.This can realize by it upwards being pressed onto in the position shown in Figure 3 with less elastic force with a spring.When pushing this pin from above, can overcome elastic force and will sell extrusion downwards.Another selection is that this pin also can make it motion by a cylinder or motor.
Before data carrier 6 gummeds, transportation bearing unit 47 moves to a block on the directions X longitudinally at correspondence gummed film 23.The part 27 of the adhesive film 25 that guarantees data carrier 6 for this reason and longitudinally align is in advance alignd mutually.Transporting bearing unit 47 is then moving around on the Z direction longitudinally perpendicular to gummed film 23.By the sensor in transportation bearing unit 47 of attaching troops to a unit to 50 profiles that detect the stamping-out part 27 of adhesive film 25, the profile of interstitial hole for example, this make data carrier 6 relatively part 27 side direction align.
, transport bearing unit 47 and hoist mobile in the above described manner not only at directions X but also after the part 27 of the relative adhesive film 25 of Z direction is alignd in data carrier 6 along the Y direction.This moment, roller 34 drove through motor 42, thereby gummed film 23 is moved along directions X.Transportation bearing unit 47 synchronously moves along directions X simultaneously and with rotation.Part 27 is bonded on the data carrier 6 and from carrier thin film 26 it and breaks away from the surface to be protected contact of data carrier 6 and by hold-down roller 33 relative compressing at this moment.By being synchronized with the movement of driven roller 34 and transportation bearing unit 47,27 pairs of the parts of adhesive film 25 centrally place on the data carrier 6, thus the side to be protected of the part of film 25 27 complete cover data carriers 6 and do not stretch out the edge.The snap-in force of hold-down roller is by the position control of transportation bearing unit 47 in the Y direction, to adjust the adhesion characteristic of pressure-sensitive adhesion film.Certainly another kind of the selection also can be that hold-down roller 33 moves to transportation bearing unit direction.For adjustment or balance snap-in force well well, a flexible suspension can be set.This suspension can realize by a spring or a pressure cylinder.
Then, have adhesive film 25 part 27 data carrier 6 by a suitable operating means 52 for example internal clamp take off and deliver to round platform shown in Figure 18 from transportation bearing unit 47.
On transportation bearing unit 47, load onto a new data carrier 6, repeat said process.As mentioned above, roller 22 and 28 is rotation continuously in whole process, although adhesion process is discontinuous carrying out.Therefore the length compensation of desired gummed film 23, as mentioned above, the tangential movement by dancer roll 31 and 37 realizes.
Although have three layers according to foregoing gummed film, promptly diaphragm 24, adhesive film 25 and carrier thin film 26 it should be noted that diaphragm 24 is optional.If but, should make roller 30 and 32 special coatings at least without diaphragm 24, becoming freely to avoid making such, adhesive film 25 would adhere on these rollers.
The another kind of selection be, also can save guide roller, and up to roller 33, in this case, roller 22 and 28 control so promptly realizes being synchronized with the movement of the alignment of part 27 and gummed film 23 and transportation bearing unit 47.
Without sensor 45 and 50, also can adopt a sensor, for example a video camera is used for above-mentioned alignment procedure.
By round platform 8, data carrier 6 is delivered to treatment bench 11 as mentioned above, in this treatment bench adhesive film sclerosis.
Fig. 4 shows the form of implementation that the banded another kind that glues together film can be used on above-mentioned gummed platform.In Fig. 4 with same Reference numeral TYP or similar part.Gummed film 23 also is made up of trilamellar membrane, i.e. the gummed film 25 of diaphragm 24, single face viscosity and carrier thin film 26.In contrast with the previous embodiment, adhesive film is not to be made of the individual layer jointing material.Specifically, the adhesive film 25 of single face viscosity is made of as the PC band one deck bonding coat 60 and layer protective layer 62.Because the PC band makes adhesive film have additional stability and this PC band also has particular optical performance, this is especially very favourable for DVR.Adhesive film 25 has foregoingly treats the size of bonding side and the part that the shape stamping-out goes out according to data carrier.In this adhesive film form, can save treatment bench 11, because the sclerosis of adhesive film is unnecessary.
The present invention has been described by the preferred embodiments of the present invention in the front, but the invention is not restricted to these specific embodiments.Data carrier can be for example be placed in its housing according to the form of disc, and this has reduced the mechanical requirement to coating greatly.In this case, treatment bench 11 can save, because no longer need other treatment step behind adhesive film (glue-line) gummed.The sclerosis of glue-line can realize by pressure and/or time and/or by radiation such as ultraviolet light or by thermal treatment.
