Abstract
The present invention relates to a bonding method and an apparatus for manufacturing optical data carriers, such as DVD9 disks and other high density optical disks. The present invention is characterized in that in order to provide an effective bonding process, a bonding station uses a dynamic balance bonding technique and/or a pulse bonding technique. The dynamic balance bonding technique ensures that the unevenness of base pieces can be effectively compensated when the two base pieces are bonded together, and therefore, dynamic unbalance degree possibly generated by one of the base pieces is reduced. The pulse bonding technique eliminates bubbles in glue for bonding the two base pieces, and high voltage for generating electromagnetic pulse can be well arranged according to the properties of the base pieces and the glue. In the transmission process of a disk after the bonding process and before the solidifying process, a clamping disk mechanism is still adopted for assuring the concentricity of the two base pieces and reducing the relatively sliding displacement of the two base pieces on the glue coating work position.
Description
Technical field
The present invention relates to a kind of method and apparatus that is used for making bonding disc, particularly be used for making the method and apparatus of optical data carrier such as DVD dish (DVD-ROM, DVD9, DVD-R/RW, DVD+R/RW and other DVD forms), AOD (Advanced Optical Disc), HD DVD Blu-ray Disc or other optical data carriers.
Background technology
Require two or more substrates are bonding mutually when making DVD, AOD or Blu-ray disc, to obtain complete optical data carrier, therefore bonding is necessary technology, and it also is one of part the most difficult in the disc production run such as DVD.A lot of possible schemes have been developed.
DVD (Data Versatile Disc) CD because have that storage density height, volume are little, advantage such as storage period limit for length, height with low cost, compatible and error rate are low, having become the main flow of present optical information recording medium, is one of most popular optical storage media.Technically, DVD is newer generation CD storage technique.It is more much bigger on numerical capacity than CD, and read or write speed is faster, can hold than CD audio frequency the video of the better film class of picture and computer data.DVD is intended to cover home entertaining, computer and commercial information with a kind of single digital format.It has been substituted laser disc, is expected to replace video-tape and video-game TV, and might finally replace audio CD and CD-ROM.DVD has obtained from all electronic enterprises and computer hardware enterprise, the support of film and music studio, and DVD has become the most successful storage medium on the CD storage technique history.Along with popularizing of multimedia (Multimedia) technology, many audio/video file data volumes are increasing, and capacity is that the single face DVD5 of 4.7G (Gigabyte) has faced limitation.The single-surface double-layer capacity is that the DVD9 of 8.5G rises at the sound, and beginning occupies a tiny space on market.The DVD-Video form is to emerge middle nineteen nineties, and in a few years, the DVD9 form has formed scale market after it emerges, and many in the world areas quantitatively surpass the home video band.The rate of growth that today, DVD9 still continued to remain ahead with bigger advantage in the CD industry.
Though blank or substantial DVD produces in the test of control, mould formation (Cheng Mo), injection moulding, metallization, printing and requirement similar to CD, but still be very different in some aspects, comprise: two substrates are bonded together additional test and the much smaller physical characteristics and the processing of specification.In order to increase output and manufacturing speed, simultaneously, also in order to reduce manufacturing cost, each step of producing DVD need all to require the attention of height.
DVD coils base, is commonly referred to transparent disc substrate or white sheet, and thickness is 0.6 millimeter, must meet very strict requirement and micron-sized tolerance.Compare with CD, the optical maser wavelength of DVD player optical head is shorter, can read littler bowl configurations and information track.Simultaneously, disc from the internal diameter to the external diameter, require to duplicate absolute unanimity and also uniformly pit to obtain high signal performance.The DVD9 of form of pre-recording requires two reflection horizon of sputter-deposited respectively: semi-reflective layer L0 and total reflection layer L1.Being used for this two-layer sputter material comprises: gold, aluminium, silicon, silver and silver alloy etc.
The L0 and the L1 substrate of the intact metallic reflector of sputter bond together by adhesive glue in a so-called bonding station, become a complete DVD9 disc after adhesive glue solidifies.Bondline thickness between two and half discs is very consistent, and controlling does not simultaneously have bubble in the bonding coat.
Bonding is a step of most critical during DVD produces, and the importance in this step is very important.Bonding that incorrect meeting makes video disc generation bending, imbalance, the arrangement of mistake, bonding coat bubble or the like defective occur.All these will cause the video disc that falls short of specifications, and these video discs can not be play with desired many speed that should have such as film and video-game.At least, the defective in this zone can cause slower transmission speed, also can cause lower output and final higher cost aborning.
After the bonding substrate of needs is handled through operations such as injection moulding, jet-plating metallization reflection horizon, directly or through intermediate storage enter a so-called bonded assemblies later on.After arriving bonded assemblies,, in this time glue assembly, treat that one of mutual bonding substrate or both go up the suitable UV adhesive glue of coating for two kinds at first by glue assembly under the ultra-violet curing adhesive glue (UV adhesive glue).Then pretreated like this two substrates are flowed to next or several merge modules, in this assembly, establish two substrates are folded mutually, and bonding mutually, wherein, guarantee between two substrate L0 and the L1 with one heart fully, mutual dislocation can not be arranged.Utilize the UV ultra violet lamp then, make the UV adhesive curing, thereby two substrates are merged together.So complete disc has just been made, and can deliver to next detection components and carry out the disc classification and deposit.
The DVD9 adhesive bonding method that uses has many different modes now, a kind of method is between the two halves sheet of DVD, at radius with a certain distance from cd centre's point, inject bonding glue with elongated syringe needle, it is bonding with the two sides to press again, so adhesive glue can be expanded inwardly outward, and then two discs that 0.6mm is thick of bonding DVD.But the yield rate of this bonding mode is not high, under assessment at angularity and signal quality, yield rate can't maintain higher level, add excessive easily glue of Internal and external cycle or starved and round, also often there is glue the outer ring and causes concavo-convex outside, therefore be easy to cause apparent flaw, cause disc to be demoted because of this outward appearance flaw.
Patent EP0735530B1 has introduced a kind of adhesive bonding method, known a kind of adhesive stations, and wherein two kinds of DVD matrix flow to a heat molten type bonding agent mutually abreast and smear station.After smearing the heat molten type bonding agent, at first a kind of matrix (matrix A) is transported to a station, in this station, UV cured bonding agent is poured in the groove of matrix, second kind of matrix (matrix B) is delivered device by a matrix and is handed to a turning device.Second kind of matrix (matrix B) upset is 180 ° there, makes it with the side that scribbles the heat molten type bonding agent down.Then by turning device this matrix being moved to first kind of matrix A goes up and is placed on above it.DVD matrix A and B this and that close picked up by another-and placing machine catches and is placed in the pressing machine, and two kinds and the DVD-matrix AB that closes are pressed into a completion DVD under pressure there.Being compressed in the vacuum chamber of DVD matrix carried out, and on its bottom a vitaglass spare arranged, and ultraviolet ray is by its irradiation DVD, so that the UV cured adhesive hardens in groove.The shortcoming of this adhesive bonding method is, all needs to smear bonding agent on matrix A and B, and greater than the edge, this causes the bonding agent that might smear on A and B in uneven thickness, therefore causes imbalance when adhesive matrix at the middle part of scraper plate pressure.
The adhesive bonding method that patent CN03158597.3 introduces is that the disc operation of substrate and merging is all carried out with circular arc, and two substrates are carried on the concentric circles of different radii.Processing stations is also with the circular arc setting, be provided with a whirligig as the central operation device, has the clamping limb that is equipped with clamping element, clamping limb can be by means of whirligig along continuous straight runs or movement in vertical direction, at least one clamping limb has two clamping elements that are provided with in turn before and after radially, when clamping limb along the circumferential direction moved, clamping element can mark the concentric circles in the true footpath of two differences.Clamping limb is scalable mobile at radial direction.Have one and be used for bonding agent and smear station, and deliver station and close station and the quality inspection station.
Some adhesive bonding methods are also arranged to force the mode of warpage, cause the upwards concave surface of bowl-type, to reduce the method that adhesive surface produces bubble or excessive glue, the method for this fix the defect is easy to introduce stress again and is deflected in first sheet of DVD, and then has influence on the inside and outside thickness of bonding coat.Have in addition and adopt the mode of serigraphy that glue is coated on the DVD CD two halves sheet in advance, bonding in addition again method, but this mode also is easy to cause bubble and dirty point, and the vestige of silk screen scraper also can remain on the cemented surface, also can cause the defective of many outward appearances.
Also has glue bond technology under a kind of central authorities, adopt central rods that are loaded with the flexible glue ring, after demifacet is inserted central rods under the DVD CD, the glue ring can be done the expansion of appropriateness, second sheet is buckled in base, this moment, glue pushed up downward material feeding by the side of central rods, base is the rotation of marginal not material limit when blanking, glue revolved turn around around central rods, insert first sheet of DVD CD to take advantage of a situation on the central rods again and slide this moment, the central authorities that are enclosed within first sheet via a cylindrical column give a slight pressure and first sheet is pressed down with second sheet combine again, so glue can be by the mediad external diffusion of DVD CD, guarantee not have the generation of bubble, except the bonding central inner ring of energy, glue can not cause the warpage of bonding sheet because of general high speed rotating causes inside and outside phenomenon in uneven thickness yet.
In the adhesive bonding method that patent US006261403 introduces, in order to reduce bubble, especially minute bubbles, when bonding, in two substrates one, especially scribble add an electrostatic field on the substrate of glue or at glue jet surface electric charge so that glue layer has static, the glue layer that has static like this is with another one half sheet when bonding, can adsorb fast and be bonded together, thereby reduce the especially generation of minute bubbles of bubble.But shortcoming is the electrostatic field instability, and the electric charge of injection is inhomogeneous, can not prevent the generation of bubble in adhesion process fully.
Summary of the invention
The purpose of this invention is to provide a kind of method and apparatus that is used for making bonding disc, this method can be in less space and short cycling time bonding DVD substrate, especially the DVD9 substrate produces the bondline thickness uniformity, does not have the DVD9 video disc of bubble.
For the DVD9 disc, L0 Information Level and L1 Information Level will accurately be bonded together, and the intermediate adhesion layer thickness is wanted uniformity, does not have bubble; Two Information Levels are wanted accurately with one heart, reduce eccentric as far as possible.By two L0 and the L1 substrate thickness of injection machine injection mo(u)lding, density can not be in full accord, always has a certain amount of off-centre (on the weight), adopted mobile equilibrium adhesive bonding method (Index Bonding) in the substrate adhesion process for this reason.The main design philosophy of this method is that the bonding as required different weight off-centre of two substrates is adjusted two angles that substrate stacks, and the center of gravity of two substrates is stacked symmetrically about the disc center, thereby reduces the weight off-centre of bonding back video disc.Be exactly the eccentric orientation of weight of measuring injection moulding substrate L0 and L1 respectively specifically, in transmitting the substrate process, guarantee that substrate does not rotate; Accurately control L1 substrate rotation, after being coated with bonding glue, pallet drives the L1 substrate and rotates, adjust substrate angle, make it with the contraposition of L0 substrate bonding after, can offset the part weight off-centre of two substrates, it is minimum that the bonding weight off-centre of video disc is afterwards dropped to, to reduce the dynamic unbalance degree of bonding back finished product video disc.
The difference of mobile equilibrium adhering technique (Index Bonding) and conventional adhesive as shown in Figure 2, can see that Index Bonding is bonding can effectively improve because the eccentric asymmetric disc dynamic unbalance degree that bring of two substrate weight.
When bonding,, reduce bubble as far as possible, invented the method for electrostatic pulse bonding (Pulse Bonding) in order accurately between L0 and L1 substrate, to form uniform adhesive glue water layer fast.Electrostatic pulse can overcome the glue surface tension, the generation of compacting reboil bubble (unborn bubble is called bubble one time in the glue); The faying face of two substrates is contacted simultaneously,, reduce the possibility that bubble produces to arrange air.Promptly when bonding disc, the bonding mechanical hand-motion L1 substrate of following glue rotating disk one side rises, when the glue of L1 just will contact with the L0 substrate, apply a time very short can the gating pulse time and the high-pressure electrostatic pulse of voltage give two substrates, allow two substrates be attached together fast, the L0 substrate contacts the back electrostatic pulse promptly to be stopped with L1 substrate glue layer.Do not having under the situation of static afterwards, two substrate L0 and L1 are bonded together under the condition of immersional wetting and pressurization, and two substrates carry out the center pit location by the centralized positioning pin of bonding mechanical arm.
