Description
Technical field
The present invention relates to a kind of by the dividing method of the adhesive substrates disjunction of two panels glass substrate and cutting device.Especially, the present invention relates to and be a kind ofly suitable for such as display panels adhesive substrates etc. to be situated between in substrate inside to put dividing method and the cutting device of the adhesive substrates disjunction of thermo-labile material.
In addition, in display panels adhesive substrates, between two panels glass substrate, form the thin film layer such as thin film transistor (TFT) or colored filter (CF), and be situated between put colored filter is separated as black matix (BM) to heat sensitive material.
Background technology
All the time, there will be a known following technology: use laser scribing method, to disjunction chap (slight crack) (such as the reference patent documentation 1) of glass substrate processing along segmentation preset lines, or by complete for glass substrate thin for thickness of slab disjunction (complete cutting processing) (such as with reference to patent documentation 2), described laser scribing method is one side illuminating laser beam, while scan, substrate produces thermal stress distribution and delineates.
In laser scribing method so far, mainly use the CO that the uptake factor of glass substrate is large
2laser etc. to carrying out scanning heating near substrate surface, and are followed described operation and spray refrigerant from the nozzle of cooling body to heating region.Thus, the stress under compression produced according to the heating because preferentially carrying out and the stress distribution of tensile stress produced because of ensuing chilling, make the surface of glass substrate produce disjunction be full of cracks, or make be full of cracks permeate the whole thickness of substrate and carry out complete cutting processing.
Carrying out in laser grooving and scribing processing to relatively thick substrate (such as thickness of slab is more than 1mm), because carrying out the impact of heat conducting relaxation time along depth direction and causing the temperature head of above-below direction, substrate surface side becomes tensile stress and the stress distribution that substrate inside (deep) side becomes stress under compression becomes major effect thus, according to the stress distribution of this above-below direction, and processing be full of cracks (slight crack).On the other hand, when for thin substrate (such as thickness of slab is about 0.2 ~ 0.3mm), produce the temperature head of depth direction hardly, so also produce the impact of the stress distribution of above-below direction hardly, but replace, stress distribution along the fore-and-aft direction of scanning pattern can impact, and when forming strong stress distribution when the stress distribution because of this fore-and-aft direction, can carry out complete cutting processing.

Summary of the invention
[inventing the problem that will solve]
Describedly utilize CO
2the complete cutting processing (laser separation processing) in the past of laser etc. has the following advantages: even if thin glass substrate, also can while keep end face strength, disjunction on one side, and preferably following aspect: can not carry out mechanical dissection process and directly by substrate-cutting (segmentation) in subsequent step, so can simplify step.
But, in described complete cutting processing, owing to only utilizing the stress distribution of the fore-and-aft direction of the scanning pattern along laser beam by substrate-cutting, so large stress-difference must be produced at fore-and-aft direction, and need the heat input of the per unit area of enough sizes.For this reason, the output rating of the laser of irradiation must be made to become large, or make sweep velocity slack-off, but no matter which kind of situation, just utilize the CO that the uptake factor on substrate surface is large
2the laser radiation of laser etc. is large and surface can produce trickle damage to the infringement caused near substrate surface.
For described situation, in patent documentation 2 (0055 hurdle), also recite the CO that replacement wavelength is 10.6 μm
2laser, and use CO laser, YAG (YttriumAluminumGarnet, Yttrium-Aluminium-Garnet) laser, excimer laser to carry out laser grooving and scribing.But, without illustrating during use CO laser in the document.
In general, as long as think and use the laser little to the uptake factor of glass substrate, then principle can suppress the absorption near substrate surface, therefore, it is possible to realize the processing suppressing surface distress, but when the laser utilizing uptake factor little is delineated, produce other problems as described below.
That is, in such as display panels adhesive substrates, the layer using thermo-labile material (such as black matrix" (BM)) is provided with in the fitting part (gaps of two plate bases) of two plate bases, therefore, if want the laser utilizing uptake factor little to carry out complete cutting processing, then the damage of substrate surface is inhibited, but then, can produce the impact of the laser because of the substrate through face side, and the damage (performance or appearance degradation) being arranged on the parts of fitting part becomes the worry of problem.
Therefore, when being carried out adding man-hour as object by adhesive substrates, in the processing of the complete cutting processing of being undertaken heating, namely laser separation, there iing the cause thermal damage caused substrate surface or fitting part to become the worry of problem by scanning laser beam.
Therefore, although the dividing processing utilizing laser of the end face excellent quality of point section originally can be carried out, be difficult to be used in the adhesive substrates that inside exists heat labile part.
On the other hand, as the complete cutting processing not producing heat affecting completely, also have and passing through while break bar (also referred to as tracing wheel) is pressed against glass substrate, while make break bar roll, and after forming the line be full of cracks, the mechanical means of disjunction is carried out along line pressing, but when making be full of cracks carry out disjunction along whole thickness direction infiltration, having the end face through disjunction to contact with each other and damaging or chap not is that through-thickness is expanded as the crow flies and departs from, and the problem that yield is deteriorated.
Therefore, the object of the present invention is to provide a kind of heat affecting that can suppress because heating during laser radiation causes adhesive substrates, and can by adhesive substrates with the dividing method of neat end face disjunction and cutting device.
[technique means of dealing with problems]
In order to reach described object, propose following technique means in the present invention.That is, the feature of dividing method of the present invention is: by least one sheet glass substrate-cutting of the adhesive substrates of laminating two panels glass substrate, and comprise: mechanical scratching step, by while break bar to be pressed against the surface of the glass substrate of disjunction object, while make break bar relative movement, and form the be full of cracks of finite depth along segmentation preset lines; And laser separation step, according to by the thermal stress distribution that produces along described be full of cracks scanning laser beam, make processing in described mechanical scratching step and the be full of cracks that obtains is permeated further and cut completely by described glass substrate; And in described mechanical scratching step, form the be full of cracks of 30 ~ 80% of thickness of slab on the surface of described glass substrate, in described laser separation step, use oscillation wavelength is that the laser of 5 mu m wavebands is split.
Herein, the laser of so-called 5 mu m wavebands is such as equivalent to CO laser specifically.
In addition, the feature of break-up device of the present invention is: by least one sheet glass substrate-cutting of the adhesive substrates of laminating two panels glass substrate, and comprise: break bar, for carrying out mechanical scratching step, described mechanical scratching step is the be full of cracks forming finite depth on the surface of the glass substrate of disjunction object along segmentation preset lines; Machining control portion, the degree of depth of the be full of cracks formed to utilize described break bar becomes the mode of 30 ~ 80% of the thickness of slab of described glass substrate, controls the pressing loading of described break bar; And laser irradiating part, for carrying out laser separation step, described laser separation step is according to by the thermal stress distribution that produces along described be full of cracks scanning laser beam, makes processing in described mechanical scratching step and the be full of cracks that obtains is permeated further, and is cut completely by described glass substrate; And the oscillation wavelength of the laser irradiated from described laser irradiating part is the laser of 5 mu m wavebands.
In described invention, the break bar used in described mechanical scratching step can use diameter to be 1 ~ 3mm and form the trough of belt break bar of groove along the crestal line becoming point of a knife.
In addition, each glass substrate applied thickness of described adhesive substrates is the glass substrate of 0.1 ~ 0.4mm.
[effect of invention]
According to the present invention, in the mechanical scratching step of preferentially carrying out, can use break bar easily the working depth thickness that is glass substrate 30 ~ 80% be full of cracks.In addition, about break bar, the break bar of the point of a knife trough of belt not easily slided preferably is used to delineate.In addition, by using trough of belt break bar, even if be low loading, the depth of penetration of be full of cracks also can be made to become described scope.And this be full of cracks by the laser separation step of follow-up use 5 mu m waveband laser (CO laser), and along the infiltration of substrate thickness direction, can carry out division processing thus.Now, the lingering section that divided part namely chaps is thin, even if so the stress distribution suppressing the heat input of laser radiation to make substrate produce diminishes, also can become complete cut state fully.Therefore, it is possible to realize utilizing the processing that inhibit the laser radiation of heat input, and the laser separation that the damage that can realize substrate surface and substrate inside is little.
And, in laser separation step, use is 5 mu m waveband lasers (CO laser) to the relatively little wave band of the uptake factor of glass, so the energy of laser beam can be suppressed only in the absorption that substrate surface is concentrated, and also can be absorbed in glass substrate inside.Thereby, it is possible to efficient and instantaneously by substrate inside heating.According to the present invention, with the CO be widely used all the time
2laser is compared, can not via thermal conduction direct heating, so with regard to this aspect, also can heat required part efficiently with few heat input.In addition, when laser (such as wavelength is the Nd ︰ YAG laser of 1064nm) that use uptake factor less than 5 mu m wavebands, energy through substrate increases, so there is the worry on the contrary substrate inside being caused to cause thermal damage, but if having the laser of the wavelength of 5 mu m wavebands, even if be then as the thin glass substrate for liquid-crystal display, also produce the heat affecting that the binding face of substrate inside is caused hardly.
Thereby, it is possible to avoid because of the heat of laser beam to the damage that the surface of glass substrate and binding face are caused, and can suppress to produce damage etc. at point section of glass substrate, can split with point section that end face strength is high and neat.
And then, with regard to CO in the past
2laser, in order to ensure heat input, the cross-sectional shape of the light beam spot of laser beam be set to ellipse and scan along rectilinear direction, but in the present invention, due to the heat input needed for segmentation can be suppressed, so the cross-sectional shape of light beam spot can be set to little circle, thus, even if when carrying out along bending line the special-shaped disjunction scanned, also having and precision can carry out the effect of disjunction well.

Embodiment
Below, based on the embodiment shown in Fig. 1 ~ Fig. 5, details of the present invention is described.In the present embodiment, the substrate of following structure is processed, described substrate be by respective thickness be 0.1 ~ 0.4mm the two panels glass substrate 1,2 be made up of thin plate laminating, and Jie puts the adhesive substrates M of the thin film layer such as TFT or colored filter 3 between this two panels glass substrate, and this thin film layer 3 also comprises the heat labile layer as black matix (BM).In addition, glass substrate uses non-alkali glass.
And, in the following description, be described for following situation: the processing carrying out being formed terminal area in the mode of a part for the substrate 1 by upside segmentation.In addition, the disjunction part of divided glass substrate 1 is removed by as scrap material.
Fig. 1 represents the figure for cutting device A of the present invention, possesses the platform 4 of mounting adhesive substrates M.Platform 4 possesses retainer member adhesive substrates M being remained on the fixed position on platform 4.In the present embodiment, as this retainer member, via the multiple little air adsorption hole (not shown) forming opening on the surface of platform 4, absorption keeps adhesive substrates M.In addition, platform 4 can be mobile in horizontal rail 5 in the Y direction (fore-and-aft direction of Fig. 1), and driven by the screw rod 6 rotated by electric motor (not shown).And then platform 4 can the turn in horizontal plane by the rotary driving part 7 of built-in motor.
The supporting pillar 8,8 that bridge formation portion 10 possesses the both sides arranged across platform 4 and the crossbeam (cross bar) 9 flatly extended in X direction, and described bridge formation portion 10 is to arrange across the mode on platform 4.
Crossbeam 9 arranges the guide rail 11 flatly extended in X direction, break bar engraving head 12 and laser irradiating part engraving head 13 are arranged on this guide rail 11 as follows: can be moved in the X direction along guide rail 11 by the travel mechanism (not shown) using electric motor 14 as drive source.At break bar with on engraving head 12, through the retainer 15 of the hoisting appliances such as cylinder 18 lifting, break bar 16 is installed, at laser irradiating part with on engraving head 13, the laser irradiating part 17 irradiated in the mode that laser beam is gathered in substrate surface is set.
In addition, in the present embodiment, represent example laser irradiating part 17 and break bar 16 being arranged on other engraving head 12,13, but also can be arranged on identical engraving head.
About break bar 16, when being used in the surface that is pressed against adhesive substrates M and rolling, can substrate processing thickness 30 ~ 80% the break bar of Thief zone be full of cracks S.In the present embodiment, as shown in Figure 2, groove (otch) 16a that uses circumferentially crestal line to be formed and residual crestal line become the trough of belt break bar formed by cemented carbide disc 16c of nose part 16b.
In addition, in the processing trough of belt break bar 16 of this Thief zone, the Penett (Penett that Samsung DIAMOND limited-liability company manufactures is had; Registered trademark) break bar and APIO (APIO; Registered trademark) break bar.The former can form darker be full of cracks S, and the latter can form the be full of cracks S more shallow than the former, so suitably can select according to processing object substrate.
The laser irradiated from laser irradiating part 17 of the present invention uses oscillation wavelength to be the CO laser of 5 mu m wavebands.The output rating of laser and sweep velocity, according to becoming the thickness of glass substrate of adhesive substrates M of processing object or material, the degree of depth of be full of cracks S of processing and different, can be selected can damage condition little as far as possible in the output rating of disjunction and the condition and range of sweep velocity.That is, it is desirable to select can output rating be made as far as possible to diminish in the scope of disjunction and sweep velocity can not become slow condition.
And then as shown in the block diagram of Fig. 5, cutting device A of the present invention possesses controller 20, input operation part 21 and display part 22.Controller 20 possesses machining control portion 23 as the functional integrant realized by computer hardwares such as CPU, RAM, ROM.Machining control portion 23 carries out the control as the inferior processing treatment action entirety to adhesive substrates M: utilize the absorption of absorption retainer member to keep adhesive substrates M, utilize screw rod 6 or rotary driving part 7 that platform 4 is moved, utilize electric motor 14 that engraving head 12,13 is moved, utilize hoisting appliance 18 make break bar 16 carry out lifting action or adhesive substrates M carried out to the output rating etc. of push action and the laser from laser irradiating part 17.Input operation part 21 be operator for inputting the interface of various operation instruction or data to cutting device A, display part 22 is for display process menu or running-active status.
Next, to using the dividing method of the present invention of described device to be described.
First, as shown in Figures 1 and 3, adhesive substrates M is positioned in platform 4, while break bar 16 to be pressed against the surface of the glass substrate 1 of upside, while make break bar 16 roll, thus, the be full of cracks S (mechanical scratching step) of finite depth is formed along segmentation preset lines.
In this mechanical scratching step, by using trough of belt break bar 16, can with low pressing loading easily the working depth thickness that is glass substrate 1 about 30 ~ 80% be full of cracks S.In addition, because trough of belt break bar not easily slides (easily blocking) on substrate, so make break bar collide glass end and be formed into the otch of triggering, thus do not carry out delineating (circumscribed) from edge of substrate, and from than edge of substrate slightly more in the inner part (inscribe) delineation.And, in the present embodiment, make the degree of depth L of be full of cracks S become about about 70% relative to the thickness 0.2mm of glass substrate 1.The degree of depth of this be full of cracks S can be undertaken by utilizing the machining control portion 23 of controller 20 to control the pressing loading of break bar 16.
Then, irradiate CO laser beam along be full of cracks S from laser irradiating part 17 scan and heat.According to the thermal stress distribution now produced, to make in the mechanical scratching step of preferentially carrying out processing and the be full of cracks S that obtain permeates along thickness direction further, and glass substrate 1 is cut (laser separation step) completely.
In addition, in the diagram, P1 represents the heating region utilizing laser beam.
In laser separation step, use oscillation wavelength is the CO laser of 5 mu m wavebands, and is not only absorbed at the near surface of glass substrate, and a part is absorbed in substrate inside, so can by substrate inside direct heating.In addition, the thickness due to substrate is thin is 0.2mm, so utilize laser radiation to be heated from the front of heating region P1 throughout back side moment, and produces the temperature head on depth direction hardly.Thus, at heating region P1, produce same stress under compression at depth direction.
On the other hand, the surrounding of heating region P1 is not heated, with heating region P1 around formation stress distribution.That is, heating region P1 produce stress under compression and around heating region P1 generation tensile stress, thus, as shown by the arrows in Figure 4, play a role with the power of the mode effect that glass substrate 1 is torn, and positively glass substrate 1 can be cut (segmentation) completely.
Especially, the laser of the CO laser used in the present invention to be oscillation wavelength described above be 5 mu m wavebands, and not only absorbed at the near surface of glass substrate, a part is absorbed in substrate inside, so can by inner for substrate direct heating, and can be efficient and will divide that section is neighbouring to be heated instantaneously.Therefore, if with the CO be all the time widely used
2laser is compared, then the loss when heat caused because of the dissipation of heat from surface moves diminishes, and can realize utilization and compare CO
2the heat input that laser is little carries out laser separation (cutting completely), so also can avoid the damage to thin film layer 3 on the one hand at this.
If supplemented further, then by the CO laser of use 5 mu m waveband, the energy through the back side (substrate private side) to glass substrate 1 can be suppressed fully.That is, when using the laser of 1 mu m wavebands such as Nd ︰ YAG laser, the energy of more than 90% do not absorbed by glass substrate and through, produce and absorbed by thin film layer 3 and cause the worry of damage, but if the CO laser of 5 mu m wavebands, then major part is absorbed in glass substrate, the energy only having 20 ~ 30% not by absorbing through.In addition, suppress to cut required energy completely by the combination with mechanical scratching step, so the heat affecting to thin film layer 3 effectively can be suppressed, and can suppress to produce damage at substrate surface, and can split with point section that end face strength is high and neat.
(embodiment)
The people such as inventor be utilize break bar 16 the glass substrate that thickness is 0.2mm to process the degree of depth be thickness of slab 70% be full of cracks after, use CO
2laser and CO laser carry out the comparative experiments of described laser separation step.
Its result, when for CO laser, can cut (segmentation) when the temperature of the irradiation position of the laser of substrate surface i.e. laser spots is 337 DEG C completely.In addition, when using CO with identical condition
2during laser, the temperature of the laser spots of substrate surface is 444 DEG C.According to described content, known CO laser can be split with the surface temperature of low about 100 DEG C.
As described above, in the present invention, the be full of cracks S of 30 ~ 80% of the thickness of break bar 16 processed glass substrate is used in the mechanical scratching step of preferentially carrying out, then, by the laser separation step of follow-up use CO laser, and make be full of cracks S along the infiltration of substrate thickness direction, thus cut completely (segmentation).Thus, namely the chap lingering section of S of the thickness of the part utilizing laser separation to process is thin, so according to the thermal stress distribution produced so that the energy of damage can not be caused to carry out heating by CO laser, positively glass substrate 1 can be cut (segmentation) completely.
And then in laser separation step of the present invention, energy when irradiating CO laser also can bring sufficient heat to the inside of substrate when utilizing circular light beam spot to scan.
By light beam spot is set to circle, and easily with curve shape non-linear shape process.That is, at use CO
2in the laser grooving and scribing in the past of laser, damage to not cause substrate surface and guarantee heat input, and the shape of the light beam spot of the laser exposed on glass substrate is set to ellipse, process in the mode that the direction of the major axis of the scanning direction with oval beam spot that make this oval beam spot is consistent.Now, shape due to light beam spot is oval, so be difficult to the nemaline processing of march, but be not the light beam spot of elliptical shape in laser separation of the present invention, can the conglobate light beam spot of shape, so without the need to making scanning direction consistent with the direction of light beam spot, the also easily nemaline processing of march.
Above, representational embodiment of the present invention is illustrated, but the present invention may not specifically for described embodiment, can reaching object of the present invention and suitably carry out revising, changing in the scope not departing from claims.
