Description

Be used to cut the system and method for substrate
The application is that application number is 200710129466.1 divides an application.
Technical field
The present invention relates to a kind of substrate diced system and method, and or rather, increase, can more effectively cut substrate along with the increase of system height and make substrate cutting work carry out reducing the production time, and can improve the substrate diced system of productivity ratio thereby relate to a kind of size of preventing locking system, and a kind ofly be used to cut substrate approach with online mode.
Background technology
Substrate comprise Semiconductor substrate and as the flat-panel monitor of image display device (flat paneldisplays, FPD).The FPD substrate comprises LCD (liquid crystal display, LCD) substrate, Plasmia indicating panel (plasma display panel, PDP) substrate and Organic Light Emitting Diode (organic light emitting diode, OLED) substrate.
The LCD substrate is made by inject liquid crystal between two sheet glass.There is shortcoming in the LCD substrate, and for example its response speed is slow and cost is higher relatively.Yet the LCD substrate has favorable characteristics aspect resolution, because it is made with semiconductor technology.Therefore, in recent years the LCD substrate as the display unit of future generation of mobile phone, computer monitor and television set and come into one's own.
Fig. 1 is the perspective view of general LCD substrate (unit substrate).Fig. 2 and Fig. 3 are the plane graphs in order to the large tracts of land initial substrates of the unit substrate that forms Fig. 1.Arrive Fig. 3 referring to Fig. 1, the LCD substrate of Fig. 1 comprises: top panel 8a (or colored filter (color filter) CF) and lower panel 8b (or thin-film transistor TFT), the two forms by glass, and partly is in contact with one another when injecting liquid crystal betwixt, from and combine; Last light polarizing film (upper polarizer film) reaches light polarizing film (lower polarizer film) (not shown) down, and it is coupled to the exposed surface of top panel 8a and lower panel 8b respectively, and provides optical characteristics in the relevant position.
The top panel 8a that is formed with color image forms less than lower panel 8b.Therefore, have liner part P on the upper surface of plate 8b below, it does not cover top panel 8a.As the IC driver of the member that is used to control a plurality of units substrate 8 with the IC driver is connected to printed circuit board (PCB) (printedcircuit board, (flexible printed circuit FPC) is coupled to liner part P to flexible print circuit PCB).
When top panel 1a and lower panel 1b combination with one another, form unit substrate 8, as shown in Figures 2 and 3.Unit substrate 8 shown in Figure 1 forms to the dozens of part by large tracts of land initial substrates 1 being cut into several.Single finished product is by to make among the liner part P of module process with the IC driver unit of being installed in substrate 8.Therefore, the technology of manufacturing substrate comprises 1 cutting of large tracts of land initial substrates or cuts into several cutting steps to the dozens of part.
Exactly, when coming the unit substrate 8 of shop drawings 1 by the single initial substrates 1 of cutting drawing 2 and Fig. 3, because the top panel 8a of unit substrate 8 and the area of lower panel 8b differ from one another, so on the top panel 1a of large tracts of land initial substrates 1 and lower panel 1b, form line of cut, cut described top panel 1a and lower panel 1b along described line of cut.Therefore, line of cut need be subjected to accurate control.For the purpose of reference, the position that the mostly position that is cut of the top panel 1a of solid line (some with dotted line overlapping and show) indication large tracts of land initial substrates 1, and dotted line indicates the lower panel 1b of large tracts of land initial substrates 1 to be cut.
The cutting step of large tracts of land initial substrates 1 is to carry out by separate payment (that is the diced system that, is called cutter or cutting equipment).Decide according to the type that supports large tracts of land initial substrates 1, known so far diced system comprises belt conveyer type (belt conveyor type) and flatbed (stage type).
The belt conveyer type has short advantage of production time, but it can't directly discharge the substrate (hereinafter being called pseudo-substrate (dummysubstrate) 3a-3d) that cuts away from large tracts of land initial substrates 1 because of reasons in structure.Pseudo-substrate 3a-3d is meant the part of not marking shade among Fig. 2 and Fig. 3.
Therefore, in belt conveyer type diced system, large tracts of land initial substrates 1 be hemisect rather than cutting fully, need to carry out the heating and cooling step and form and breaks.Then, large tracts of land initial substrates 1 is finally cut, thereby forms unit substrate 8.
On the contrary, according to Platform Type, when mobile large tracts of land initial substrates 1 at will partly locate to form line of cut, because there is not the problem of discharging pseudo-substrate 3a-3d in it.Large tracts of land initial substrates 1 is fitly cut fully along line of cut, thereby forms unit substrate 8.
Yet as mentioned above, because being top panel 1a and the lower panel 1b by combination with one another, large tracts of land initial substrates 1 forms, and the top panel 1a and the lower panel 1b that are formed on large tracts of land initial substrates 1 upward differ from one another with the line of cut by the cutting unit of formation substrate 8, so the flatbed diced system needs a kind of member, it is used for whole large tracts of land initial substrates 1 being rotated or overturning 180 °, with the top panel 1a of cutting large tracts of land initial substrates 1 and any one among the lower panel 1b, then cut other one.
Yet, in the flatbed diced system, as mentioned above, need provide corresponding with it turner or inversion structures, so that reverse whole large tracts of land initial substrates 1, with the top panel 1a of cutting large tracts of land initial substrates 1 and each among the lower panel 1b.In addition, because the minimum space of the large tracts of land initial substrates 1 that need be used to reverse,, make the corresponding increase of size of system so system height can increase.
Simultaneously, in belt conveyer type diced system, as mentioned above, large tracts of land initial substrates 1 is not cut but hemisect fully, and experience heating and cooling step forms and break, and large tracts of land initial substrates 1 just finally is cut like this.Therefore, though pseudo-substrate 3a-3d need be transmitted continuously by being attached to large tracts of land initial substrates 1, and cut fully after the heating and cooling step, pseudo-substrate 3a-3d is cutting in advance during transmitting.Therefore, unit substrate 8 will might be damaged during transmission large tracts of land initial substrates 1 in order to the liner part P that the IC driver is installed very much.
Can cut into preliminary dimension by installation circuit in substrate and with substrate, and will be used for the flat board of chip and flat display devices as the substrate of electronic unit material.Substrate can be the wafer that is used to form semiconductor chip and is used for the flat board (for example, LCD panel, PDP panel and oled panel) of flat display devices.Exactly, because the LCD substrate drives by inject liquid crystal between two substrates, so with combination with one another about two substrates, and then it is cut and makes its fracture.
In general substrate, on substrate surface, form line of cut, and the temperature that change to form the substrate part at line of cut place is broken with formation, and substrate ruptures along line of cut, so just can obtain to have the semiconductor chip of the size of wanting and the flat board of flat display devices.
Yet when forming line of cut on substrate surface, when the line of cut degree of depth was more shallow, substrate was difficult to fracture, even and substrate cracking, break surface is also not too neat.In order to solve described problem, when cutting head forms line of cut on substrate surface, for example use equipment such as servo motor, cam and gear to push substrate surface with predetermined pressure, therefore the described line of cut of cutting under this state increases the line of cut degree of depth.Yet the complex structure of described equipment for the response variation of change in torque, and is difficult to it is controlled, so the performance and the degradation of substrate cutting.
In addition, in as mechanical components such as cam or gears, foreign material and dust be can produce, and a large amount of mechanical parts, for example retainer (stopper), spring and gear needed.Therefore, operational environment is unclean, and the degraded accuracy in the substrate cutting step.
Summary of the invention
In order to solve above and/or other problems, the invention provides a kind of substrate diced system and method, thereby it can prevent that the size of locking system increases, can more effectively cut substrate and makes substrate cutting work carry out to reduce the production time, also can improve productivity ratio with online mode along with the increase of system height.

Arrive Fig. 8 referring to Fig. 4, mainly referring to Fig. 4 and Fig. 5, substrate cutting equipment according to the embodiment of the invention comprises: first lower platform 110, upper mounting plate 130 and second lower platform 160, described platform all is provided on first to the 4th active line W1-W4, and described active line is along the direction layout parallel to each other of large tracts of land initial substrates 1 being carried out cutting work; And distributor 170, cross drive device 175, inversion device 185 and discharge conveyer 190, it is arranged in substrate cutting equipment back.
The substrate cutting equipment comprises: go up cutting module 120, it is provided at first lower platform, 110 tops; Following cutting module 140, it is provided at upper mounting plate 130 belows; And discharge section 150, it is provided at down cutting module 140 belows, to discharge the pseudo-substrate 3a-3d that cuts away from large tracts of land initial substrates 1.
Above element can carry out a series of activities, and the large tracts of land initial substrates 1 that wherein comprises Fig. 2 is input to first lower platform 110; Carry out predetermined cuts work to form the unit substrate 8 of Fig. 1; And be discharged to and discharge conveyer 190.Therefore, because large tracts of land initial substrates 1 can be based upon Wiring technology (inline proces s), so can reduce the production time and can boost productivity in addition.And,,, can prevent that so just system dimension from increasing so can reduce system height because the substrate cutting equipment need not to be used to the structure of whole large tracts of land initial substrates 1 of reversing or overturn.
The large tracts of land initial substrates 1 of Fig. 2, the unit substrate 8 of Fig. 1 and the moving direction of cut direction or platform 110,130 and 160 are at first described.The large tracts of land initial substrates 1 of Fig. 2 is the parent that is used for forming the unit substrate 8 of Fig. 1.Therefore, in the present embodiment, the unit substrate 8 of 12 dash area indicator diagrams 1 of the large tracts of land initial substrates 1 of Fig. 2.
In addition, the top panel 1a of the most of solid line that illustrates among Fig. 2 (some is because of showing with dotted line is overlapping) indication large tracts of land initial substrates 1 is by the position of last cutting module 120 cuttings, and the lower panel 1b of dotted line indication large tracts of land initial substrates 1 is by the position of cutting module 140 cuttings down.The remainder indication that does not add shade is discharged to the pseudo-substrate 3a-3d of discharge section 150.
The same with unit substrate 8, large tracts of land initial substrates 1 comprises top panel 1a and lower panel 1b, and described top panel 1a and lower panel 1b are made by the glass of two combinations with one another.Face up and under the ventricumbent state of lower panel 8b as thin-film transistor TFT, unit substrate 8 finally is placed on discharges on the conveyer 190 as shown in Figure 1 at top panel 8a, and then unit substrate 8 is discharged for reprocessing as colored filter CF.
Yet, before cutting step, be entered into the first active line W1 mutually on the contrary by large tracts of land initial substrates 1 being inverted to unit substrate 8.That is to say, face up as the top panel 1a of TFT, and face down as the lower panel 1b of CF.In this state, large tracts of land initial substrates 1 is input to the first active line W1, and carries out a series of cutting steps.
In the present embodiment, by diced system the large tracts of land initial substrates 1 of Fig. 2 is cut into 12 unit substrates 8 altogether.First to the 4th active line W1-W4 is a Y direction with respect to the direction that the moving direction of cut direction or platform 110,130 and 160 is formed parallel to each other, and is X-direction perpendicular to the direction of first to the 4th active line W1-W4.
In the structure of formation according to each element of the substrate cutting equipment of present embodiment, first lower platform 110 supports the large tracts of land initial substrates of being imported 1 and also is coupled to the first active line W1, so that can move on Y direction along the first active line W1.Can use linear movement accurately to control moving of first lower platform 110.
First lower platform 110 is from the described large tracts of land initial substrates 1 of lower support of the large tracts of land initial substrates 1 that is input to the first active line W1.Therefore, when large tracts of land initial substrates 1 being placed on first lower platform 110, the lower panel 1b of large tracts of land initial substrates 1 is contained in the upper surface of first lower platform 110 and thus and supports.
Though explanation large tracts of land initial substrates 1 will be by on the upper surface that is contained in first lower platform 110 and supported among the figure, the operation of lip-deep a plurality of lifter pins (lift pin) (not shown) that large tracts of land initial substrates 1 also can be by being provided at first lower platform 110 is contained on the upper surface of first lower platform 110.
That is to say that when independent manipulator (not shown) was loaded in large tracts of land initial substrates 1 on the upper surface of first lower platform 110, lifter pin rose the lower surface with the lower panel 1b that supports large tracts of land initial substrates 1.Then, lifter pin descends, thereby large tracts of land initial substrates 1 is contained on the upper surface of first lower platform 110 and supports thus.
When large tracts of land initial substrates 1 is contained on the upper surface of first lower platform 110 and supports thus, be contained on the upper surface of first lower platform 110 and the large tracts of land initial substrates 1 that supports thus by the independent vacuum line absorption on the upper surface of first lower platform 110.Therefore, large tracts of land initial substrates 1 is fixed on fixing position, and can not move arbitrarily on the upper surface of first lower platform 110.On the contrary, when discharging large tracts of land initial substrates 1 from the upper surface of first lower platform 110, lifter pin rises, so that large tracts of land initial substrates 1 is risen to predetermined altitude.
Because the structure of lifter pin and operation not only are applicable to first lower platform 110, and similarly are applicable to second lower platform 160 and upper mounting plate 130, so will omit it are described further.Yet, absorption (absorption) operation to large tracts of land initial substrates 1 will be described in appropriate section in more detail.
Last cutting module 120 is provided in the upper area of first lower platform 110, and by forms on the upper surface 1a of the large tracts of land initial substrates 1 that supports by first lower platform 110 be scheduled on line of cut cut large tracts of land initial substrates 1 (please referring to Fig. 6).Last cutting module 120 comprises: cross tube (uppercross bar) 121, and it is fixed in the zone of location first lower platform 110 along the direction perpendicular to the length direction of the first active line W1; And a plurality of cutters 123 of going up, it is coupled to cross tube 121 1 sides.
Though first lower platform 110 is moving on the first active line W1 on the Y direction, cross tube 121 is fixed on the corresponding position and only is coupled to the last cutter 123 of cross tube 121 removable.Further the opposite side at cross tube 121 provides the upper lines of observing line of cut to observe part 125.Can be by determining to go up the position of cutter 123 on cross tube 121 based on the control of observing part 125 observed images by upper lines.
Last cutter 123 comprises: go up holder 123a, it is coupled to cross tube 121; And on cut tool 123b, it forms line of cut on the top panel 1a of large tracts of land initial substrates 1, described large tracts of land initial substrates 1 moves by being supported by first lower platform 110.Last holder 123a can relatively move on cross tube 121.
Therefore, when forming line of cut on the top panel 1a in the large tracts of land initial substrates 1 of Fig. 2 with the large tracts of land initial substrates 1 that is of uniform thickness thick of cutting and top panel 1a, along with first lower platform 110 with respect to moving of the last cutter 123 that is fixed in a certain position and the cutting work on the execution Y direction.When first lower platform fixedly the time, along with last cutter 123 when mobile, is being carried out the cutting work on the X-direction on the X-direction on cross tube 121.Therefore, with the top panel 1a execution cutting work of said method to large tracts of land initial substrates 1.
As shown in Figure 6, even when the top panel 1a of large tracts of land initial substrates 1 being carried out cutting work and produce the pseudo-substrate 3b in pseudo-substrate 3a and end in the above among the plate 1a, because large tracts of land initial substrates 1 is supported by first lower platform 110, so pseudo-substrate 3a can't separate from large tracts of land initial substrates 1 with the pseudo-substrate 3b in end.By the operation of the following cutting module 140 of description after a while, pseudo-substrate 3a is separated from large tracts of land initial substrates 1 with the pseudo-substrate 3d in end with the pseudo-substrate 3c that produces from lower panel 1b with 3b.
Upper mounting plate 130 is by supporting large tracts of land initial substrates 1 from top absorption large tracts of land initial substrates 1, wherein used cutting module 120 to finish cutting work to the top panel 1a of large tracts of land initial substrates 1.That is to say that different with first lower platform 110, the top panel 1a of upper mounting plate 130 absorption large tracts of land initial substrates 1 is to promote large tracts of land initial substrates 1.Therefore, upper mounting plate 130 is arranged to be higher than first lower platform 110, and is designed to be able to relatively move with respect to first lower platform 110.
In order to make the top panel 1a of upper mounting plate 130 absorption and lifting large tracts of land initial substrates 1, upper mounting plate 130 comprises a plurality of lifter pins (not shown) as first lower platform 110.Yet, different with first lower platform 110, preferably form vacuum line (not shown) in each lifter pin in being provided in upper mounting plate 130 in order to absorption large tracts of land initial substrates 1.
Therefore, when the lifter pin of first lower platform 110 be raised with large tracts of land initial substrates 1 when first lower platform 110 rises to predetermined altitude, the lifter pin of the upper mounting plate 130 that moves above first lower platform 110 is lowered, with the upper surface of the top panel 1a of contact large tracts of land initial substrates 1.When forming vacuum by vacuum line (vacuum line), large tracts of land initial substrates 1 is adsorbed.When large tracts of land initial substrates 1 was adsorbed, the lifter pin of upper mounting plate 130 can be raised, and made the top panel 1a of large tracts of land initial substrates 1 can contact the lower surface of upper mounting plate 130 and support thus.
Except the structure of lifter pin and vacuum line, can use electrode electrostatic chuck (electrodestatic chuck) to replace upper mounting plate 130, described electrode electrostatic chuck makes the electricity consumption friction adsorb large tracts of land initial substrates 1.Large tracts of land initial substrates 1 is being moved to the process of upper mounting plate 130 from first lower platform 110, and upper mounting plate 130 moves towards first lower platform 110, and perhaps first lower platform 110 moves towards upper mounting plate 130.
Following cutting module 140 by form on the lower panel 1b of the large tracts of land initial substrates 1 adsorbed by upper mounting plate 130 predetermined on line of cut cut large tracts of land initial substrates 1 (please referring to Fig. 7).Following cutting module 140 comprises: sheer pole 141, and it is fixed in the zone of location upper mounting plate 130 along the direction perpendicular to the length direction of the second active line W2; And a plurality of cutters 143 down, it is coupled to sheer pole 141 1 sides.
Though upper mounting plate 130 is moving on the second active line W2 on the Y direction, sheer pole 141 is fixed on the relevant position and only is coupled to the following cutter 143 of sheer pole 141 removable.Further the opposite side at sheer pole 141 provides the lower line of line of cut under the observation to observe part 145.Can be by determining the position of cutter 143 on sheer pole 141 down based on the control of observing part 145 observed images by lower line.

Figure 24 explanation is according to the structure of the substrate diced system of fifth embodiment of the invention.Figure 25 illustrates the side of the substrate cutting equipment of Figure 24.
Referring to Figure 24 and Figure 25, substrate diced system 500 comprises: cutting head 510, and its cutting substrate 1 is to form line of cut on substrate 1; Linear motor 520, it raises cutting head 510; Cutting head transmitting portions 530, it transmits cutting head 510 on X-direction; Substrate transfer part 540, it transmits substrate 1 on Y direction; Measure portion 550, it measures the cutting pressure of cutting head 510; And controller 560, it controls above-mentioned parts with electric mode and mechanical system.
Cutting head 510 forms line of cut on the surface of substrate 1, and comprises: raise guider (elevation guide) 511, it is coupled to rod (rod) 511a, and guiding cutting head 510 moves up and down; Tip holder strutting piece 512, it is coupled to raises guider 511, and it can rotate relatively; Tip holder 513, it is connected to tip holder strutting piece 512, and restriction cuts most advanced and sophisticated (the cutter wheel tip) 514 of tool wheel, and the described tool wheel most advanced and sophisticated 514 cut is coupled to tip holder 513 in rotatable mode, and forms line of cut on substrate 1 surface; And carriage 515, it is from raising the side-prominent of guider 511, and uses and following the dynamometer of describing (load cell) 551 is measured cutting pressures.
Raise guider 511 cutting head 510 that when raising, leads and move up and down, hereinafter will describe linear motor 520 by linear motor 520.Therefore, can use normally used linear steering device to implement to raise guider 511.
Tip holder strutting piece 512 supports the tip holder 513 of its below, and is coupled to the lower part of raising guider 511, and described strutting piece can rotate relatively.Therefore, when when forming line of cut on the surface of substrate 1 on X-direction, the blade of cutting tool wheel most advanced and sophisticated 514 points to X-direction.When forming line of cut on the surface of substrate 1 on Y direction, the blade half-twist of cutting tool wheel most advanced and sophisticated 514 is to point to Y direction.
Cut most advanced and sophisticated 514 the surfaces of tool wheel and form line of cut, and be coupled to tip holder 513 in rotatable mode by direct contact substrate 1.That is to say, when cutting tool wheel most advanced and sophisticated 514 and rotate in contact, on the surface of substrate 1, form line of cut by mobile cutting head 510 on surface with substrate 1.
Cut the directly surfaces of contact substrates 1 of tool wheel most advanced and sophisticated 514, make the contact surface generation plastic deformation of substrate 1.When surpassing the critical point of plastic deformation, the direction of pushing at the blade of cutting tool wheel most advanced and sophisticated 514 or on the thickness direction of substrate 1, form the crack.Yet when the power of the blade of cutting tool wheel most advanced and sophisticated 514 of pushing substrate 1 was excessive, the crack can reach capacity, thereby forms on undesirable direction, rather than forms on the thickness direction of substrate 1.That is to say, because the crack is inwardly to form in substrate 1 rather than form on the thickness direction of substrate 1, so the Performance And Reliability of the flat board of semiconductor chip or panel display apparatus can be degenerated.On the contrary, when the power of the blade of cutting tool wheel most advanced and sophisticated 514 of pushing substrate 1 was too small, the crack formed fully inadequately, made and suitably cut in fracture process, thereby make the quality degradation of cutting performance and substrate 1.Therefore, the pressure of cutting tool wheel most advanced and sophisticated 514 by control among the substrate cutting method S500 of Miao Shuing makes it constantly be default reference pressure hereinafter, even also like this during substrate 1 in uneven thickness, make the line of cut degree of depth even, make on the thickness direction of substrate 1, accurately to form line of cut.
Provide carriage 515 in cutting head 510 1 sides, and carriage 515 is along with cutting head 510 moves up and down.Exactly, carriage 515 directly contacts the dynamometer of describing after a while 551, makes dynamometer 551 can measure the falling pressure of cutting head 510.Therefore, as shown in figure 25, carriage 515 is preferably outstanding from cutting head 510, and is arranged in dynamometer 551 tops.In addition, be defined as the cutting pressure of cutting head 510 owing to therefore will push the pressure of the carriage 515 of dynamometer 551, thus carriage 515 must be connected to cutting head 510 by rigid body, and carriage 515 is preferably formed by the material with less strain.
In Figure 24 and Figure 25, carriage 515 is illustrated as to be provided at and raises guider 511 fronts.Yet coupling position is not limited to this, and any position all is possible, as long as carriage 515 raises integratedly with cutting head 510 and the cutting pressure of cutting head 510 is passed to dynamometer 551.
Linear motor 520 is raised cutting head 510 on vertical direction (being Z-direction).That is to say, consider it is in clean room, to make the high-tech equipment that needs high cleanliness and accuracy, so as the assembly that is used on vertical direction (being Z-direction), raising cutting head 510, preferably use linear motor particularly the linear voice coil motor (voice coil motor, VCM).VCM is that a kind of electric power produces equipment (power generating apparatus), and it uses electromagnetic force that motor is moved with linear mode, and described electromagnetic force is to produce by the interaction between the electric current that flows in magnetic force that is produced by magnet and the voice coil loudspeaker voice coil.
When using VCM, can significantly reduce the possibility that produces noise and dust, response speed accelerates, and control becomes easily, and has simplified mechanical structure.Exactly, when the linear motor 520 of raising cutting head 510 is when being formed by VCM, only by the electric current that flows in VCM is controlled, just can be easily and accurately control the cutting pressure of cutting head 510.In addition, because response is very fast, so can accurately form the thickness of line of cut.
Cutting head transmitting portions 530 is transmitted cutting head 510 on X-direction, and can form by driving unit, and described driving unit for example is the linear motor that produces electric power on X-direction.Cutting head transmitting portions 530 is appropriately controlled by controller 560 with substrate transfer part 540 (hereinafter will describe).Therefore, can form on the surface of substrate 1 on the X-direction line of cut and with X-direction on the Y direction of cuts intersect on line of cut.
Substrate transfer part 540 is transmitted substrate 1 on Y direction, and can be by forming by rotating the transfer cylinder 540 of transmitting substrate 1 contiguously with substrate 1.In Figure 24, transfer cylinder only is illustrated as to be provided below the substrate 1.Yet transfer cylinder 540 can be provided at the top and the below of substrate 1, to contact with each other through pushing and to rotate, transmits substrate 1.Yet the present invention is not limited to this, and substrate transfer part 540 can be formed by normally used belt conveyer.
In addition, substrate transfer part 540 can further comprise substrate and grasp unit (not shown), is used to grasp substrate 1, with prevent substrate 1 transmit substrate 1 or in substrate 1, form line of cut during twined or shaken.Substrate grasps unit and is formed by clamp (clamp), and described clamp clamps between substrate 1 or insertion substrate 1 and the transfer cylinder 540 and uses vacuum to grasp the vacuum adsorption plate of substrate 1.Yet this aspect is not limited to this.
Measure portion 550 is measured the cutting pressure of the cutting head of being pushed by linear motor 520 510 downwards, and the cutting pressure of measuring is passed to controller 560.Therefore, measure portion 550 comprises: dynamometer 551, and it is arranged on the descent path of carriage 515 of cutting head 510 with contact carriage 515, and measures the cutting pressure of cutting head 510; And strutting piece 552, it is arranged on the descent path of carriage 551, and supports dynamometer 551.
Measure portion 550 preferably is mounted to the cutting path of substrate 1 spaced a predetermined distance from.That is to say, earlier cutting head 510 is delivered to measure portion 550, and measures and adjust the cutting pressure of cutting head 510 before the cutting work beginning substrate 1 carried out.Then, cutting head 510 is delivered to the cutting path of substrate 1 to begin cutting work.When measure portion 550 being mounted to the cutting path of substrate 1 when spaced a predetermined distance from, the structure of substrate transfer part 540 is also uncomplicated, and measure portion 550 can not disturbed the cutting work of cutting head 510.
Dynamometer 551 contact carriages 515, and the cutting pressure of measurement cutting head 510, and the value that will measure passes to controller 560.Dynamometer 551 is Weight-measuring devices of making in the following manner: (strain gauge) is attached on the metallic elastic body with straingauge, and exports elastomeric deformation rate according to the load of elastomer signal.Therefore, along with cutting head 510 descends, the carriage 515 that is attached to cutting head 510 is pushed the dynamometer 551 that is arranged on the descent path.Then, the elastomeric deformation rate of dynamometer 551 is detected as the signal of telecommunication, and the signal of telecommunication is passed to controller 560 by transducer with the form of analog signal.Because controller 560 comprises the database according to the calculated value in advance of the cutting pressure that detects the signal of telecommunication, so can be by also accurately know the cutting pressure of cutting head 510 fast from dynamometer 551 electrical signal delivered.

To provide detailed description by describing the substrate cutting method S500 of substrate diced system 500 according to another embodiment of the present invention about controller 560.
Figure 26 illustrates the cutting operation of the substrate diced system of Figure 24, and wherein cutting head moves above dynamometer.Figure 27 illustrates the cutting operation of the substrate diced system of Figure 24, and wherein carriage is pushed dynamometer.Figure 28 illustrates the cutting operation of the substrate diced system of Figure 24, wherein cutting head cutting substrate.Figure 29 illustrates the substrate that the substrate diced system of Figure 24 is cut.Figure 30 is the flow chart of substrate cutting method that illustrates the substrate diced system of Figure 24 in regular turn.
Referring to Figure 26 to Figure 30, cutting head transmitting portions 530 (+X) transmit cutting head 510 on the direction of principal axis, make carriage 515 arrive the top of dynamometers 551.When carriage 515 arrives the top of dynamometer 551, apply electric current (S510) to VCM 520.
When VCM 520 applies electric current, cutting head 510 is because the electromagnetic force that is produced by the interaction of magnet and voice coil loudspeaker voice coil descends.When cutting head 510 descends,, make the cutting pressure of cutting head 510 be delivered to dynamometer 551 from the outstanding forward carriage 515 contact dynamometers 551 of cutting head 510.
When carriage 515 when dynamometer 551 is exerted pressure, dynamometer 551 is measured the cutting pressure (S520) of cutting heads 510.That is to say that the elastomer of dynamometer 551 is out of shape because of the pressure of carriage 515, and deformation rate is detected and be delivered to controller 560 as the signal of telecommunication.
Controller 560 searches out from the database of preparing in advance according to the signal of telecommunication corresponding to the cutting pressure value by the dynamometer 551 detected signals of telecommunication, and cutting pressure that searches and the reference pressure of presetting are compared (S530).
When controller 560 compares and find cutting pressure less than reference pressure (N) with the cutting pressure of cutting head 510 and default reference pressure, will be applied to VCM 520 (S540) greater than the electric current of initial current.Improve the cutting pressure of cutting heads 510 greater than the VCM 520 of the electric current of initial current by reception.Dynamometer 551 detects the cutting pressure (S520) that improves once more by carriage 515.Control section 560 compares (S530) with the cutting pressure that remeasures and the reference pressure of cutting head 510.Repeat above-mentioned steps till cutting pressure is identical with reference pressure (Y).
When controller 560 compares and find cutting pressure greater than reference pressure (N) with the cutting pressure of cutting head 510 and default reference pressure, will be applied to VCM 520 (S540) less than the electric current of initial current.Repeat above-mentioned steps, till cutting pressure is identical with reference pressure (Y).
When controller 560 compares and finds that with the cutting pressure of cutting head 510 cutting pressure and reference pressure (Y) are identical with preset reference pressure, controller 560 is stored (S550) with electric current as finally applying electric current, and applies the described electric current that applies to VCM 520 in cutting technique.
After finding to be applied to the electric current of VCM 520, begin to carry out cutting technique about substrate 1 by above-mentioned steps.At first, forming on X-direction on the substrate 1 in the step of cutting, cutting head transmitting portions 530 (X) is being delivered to the top (S560) of cutting initial point 1a (please referring to Figure 29) open of substrate 1 with cutting head 510 from measure portion 550 on the direction of principal axis.Simultaneously, substrate transfer part 540 (Y) is being transmitted substrate 1, is being made the initial point 1a that cuts open of substrate 1 be positioned at cutting head 510 belows on the direction of principal axis.
When cutting head 510 be positioned at substrate 1 cut initial point 1a place open the time, apply electric current (S570) to what VCM 520 applied controller 560 storage.When VCM 520 applies electric current, cutting head 510 descends, and cuts the surface of the most advanced and sophisticated 514 contact substrates 1 of tool wheel.Along with cutting head 510 (X) is moving the surface (S580) of cutting substrate 1 by cutting head transmitting portions 530 on the direction of principal axis.Generally speaking, in the case, cutting head 510 cuts several times repeatedly with identical line of cut, so that accurately form the line of cut of the degree of depth of wanting.X-axis and Y-axis be interpolation in its operation.
When on substrate 1, forming line of cut on the X-direction, substrate transfer part 540 with substrate 1 (+Y) transmit preset distance on the direction of principal axis.Then, cutting head 510 forms new line of cut on the X-axis of substrate 1.
When by repeating above-mentioned steps successively when in X-direction, forming a plurality of line of cut on the substrate 1, form the line of cut on the Y direction with the cuts intersect of X-direction.That is to say that cutting head transmitting portions 530 is transmitted cutting head 510 on X-direction, make it be positioned the new initial point 1b top (S560) of cutting open of substrate 1.Simultaneously, substrate transfer part 540 (Y) is being transmitted substrate 1, is being made the initial point 1b that cuts open of substrate 1 be positioned at cutting head 510 belows on the direction of principal axis.
In the case, tip holder strutting piece 512 makes the blade of cutting tool wheel most advanced and sophisticated 514 point to the direction that is parallel to Y-axis with respect to raising guider 511 half-twists.Then, apply electric current (S570) to what VCM 520 applied that controller 560 stored.
When VCM 520 applies electric current, cutting head 510 descends, and makes to cut the surface that tool wheel most advanced and sophisticated 514 contacts substrates 1.Therefore, substrate transfer part 540 (+Y) transmit substrate 1 on the direction of principal axis, make that the surface of substrate 1 is cut (S580).X-axis and Y-axis be interpolation in its operation.
When the line of cut on the Y-axis that forms substrate 1, cutting head transmitting portions 530 (X) is being transmitted preset distance on the direction of principal axis.Then, when substrate transfer part 540 (+Y) transmit on the direction of principal axis when cutting the substrate 1 that tool wheel most advanced and sophisticated 514 contacted, on the Y-axis of substrate 1, form new line of cut.
When forming a plurality of line of cut by repeating above-mentioned steps successively on the Y-axis of substrate 1, the substrate 1 that is formed with line of cut enters the fracture step, and fragments into a plurality of chips or panel along line of cut.
According to present embodiment,,, make successive substrates fracture step become easily, and can improve the performance and the quality of the fracture of substrate 1 so the degree of depth of the line of cut that forms on the substrate 1 increases because the cutting pressure of cutting head 510 accurately mates default reference pressure.
In addition, because the linear moment of torsion of VCM 520 is directly transferred to cutting head 510, so very fast to the response of linear change in torque.In addition, owing to can be applied to the cutting pressure that electric current is easily controlled cutting head that applies of VCM 520 by control, so can improve the performance of the fracture of substrate 1 largely.
