The mistake of the first X-axis cutting line XL1 and the second X-axis cutting line XL2 is formed in the first face S1 and the second face S2 of substrate S Journey

In, substrate S is adsorbed and be fixed by the second plate 760.

During substrate S is moved to subsequent handling from the second plate 760, gas is supplied to the groove portion of the second plate 760, by This, substrate S can be with the second plate 760 without frictionally being moved.

Also, the second transfer unit 700 further includes going up and down module 750 for going up and down the plate of the second plate 760.Plate goes up and down module 750 are set to the lower section to the extended guide rail 720 of Y direction, for going up and down the second plate 760 and belt 710 together.But this Invent without being limited thereto, plate lifting module 750, which can connect, goes up and down the second plate 760 in the second plate 760.Implement according to the present invention Example can go up and down module 750 by a plate to go up and down the second plate 760.But the invention is not limited thereto, and plate goes up and down module 750, It also may include that the plate decline module 751 for declining the second plate 760 and the plate for rising the second plate 760 rise module 752.

Plate lifting module 750, plate decline module 751 or plate rise module 752 can be by pneumatics or oil pressure operation Actuator, according to electromagnetic interaction operation linear motor or ball screw device isoline mobile device.

As shown in Figure 10, during substrate S is transferred to the second plate 760 from the first plate 660, the second plate 760 passes through plate Decline module 751 and declines preset distance.Thus, it is possible to prevent from entering the top Shi Yu of the second plate 760 at the leading end of substrate S The phenomenon that front end conflict of two plates 760.

Also, during as shown in figure 11, mobile from the first plate 660 in the second plate 760 and substrate S is separated, second Plate 760 rises module 752 by plate and rises preset distance.Thus, it is possible to along the first X-axis cutting line XL1 for being formed in substrate S And the second X-axis cutting line XL2 concentrated stress, substrate S can be along the first X-axis cutting line XL1 and the second X-axis cutting line as a result, XL2 is smoothly separated.

Or if there is the plate lifting module 750 for going up and down the second plate 760, in the process of separating base plate S In, the second plate 760 can go up and down module 750 by plate and rise or fall preset distance.The rising and decline of second plate 760 can be with Pre-determined number repeatedly.Stress is collected along the first X-axis cutting line XL1 and the second X-axis cutting line XL2 for being formed in substrate S as a result, In, substrate S can smoothly be separated along the first X-axis cutting line XL1 and the second X-axis cutting line XL2 as a result,.

Said effect not only can the generation when substrate S is separated into unit substrate, from substrate S remove dummy portions when It can similarly generate.

Or as shown in figure 12, the first plate 660 can A1 be obliquely installed at a predetermined angle in the transfer direction of substrate S. In the same manner, the second plate 760 is also tilted by a predetermined angle on the transfer direction of substrate S A2 and is arranged.That is, the first plate 660 and second Plate 760 can have the surface being tilted by a predetermined angle relative to substrate S.

In embodiments of the present invention, the first plate 660 and the second plate 760 can be tilted all.At this point, the first plate 660 and second Plate 760 can be to inclined.But the present invention is not limited thereto, is also possible in the first plate 660 or the second plate 760 Only one inclination.I.e., the first plate 660 and the second plate 760 are obliquely arranged with different directions towards each other.

In addition, the first plate 660 and the second plate 760 are arranged with angle tilt different from each other.

In addition, the inclined angle of the first plate 660 and the inclined angle of the second plate 760 are unspecified angle in 0 to 45 degree.

For example, the first plate 660 can A1 be tilted down at a predetermined angle towards the transfer direction of substrate S.Another example, first Plate 660 can A1 be tilted upwards at a predetermined angle towards the transfer direction of substrate S.

Or second plate 760 can A2 tilts down setting at a predetermined angle towards the transfer direction of substrate S.It is another Example, the second plate 760 can A2 be obliquely installed upwards at a predetermined angle towards the transfer direction of substrate S.

In the embodiment of the present invention, towards the transfer direction of substrate S, A1 tilts down setting to the first plate 660 at a predetermined angle, Towards the transfer direction of substrate S, A2 tilts down setting to second plate 760 at a predetermined angle.

It is as shown in figure 13, mobile far from the first plate 660 in the second plate 760 according to above structure, and cut along the first X-axis During secant XL1 and the second X-axis cutting line XL2 separating base plate S, the end of separated two unit substrates can be prevented Sliding (friction) between P1, P2.Thus, it is possible to prevent the cunning between end P1, P2 because of two unit substrates separated The breakage of substrate S caused by dynamic (friction), and the substrate S's because of caused by scratch or electrostatic etc. caused by sliding (friction) are broken Damage.

The said effect not only generation when substrate S is separated into unit substrate, when the dummy portions of substrate S are eliminated Can equally it occur.

The effect of mobile device 730 is: by making the second plate 760 and belt 710 along the extended guide rail 720 of Y direction It is moved back and forth to Y direction.Mobile device 730 can be by pneumatics or the actuator of oil pressure operation, according to electromagnetism phase interaction With the linear motor or ball screw device isoline mobile device of operation.

As shown in figure 22, it after substrate S forms the first X-axis cutting line XL1 and the second X-axis cutting line XL2, is inhaled in substrate S In the state of investing the first plate 660 and the second plate 760, the second plate 760 by mobile device 730 far from the first plate 660, then substrate S can be separated along the first X-axis cutting line XL1 and the second X-axis cutting line XL2.

As shown in figure 14, mobile device 730 is connect with control unit 1000, and controlled unit 1000 is controlled.Mobile dress Set 730 load measurement modules 1100 for being connected with load for measuring mobile device 730.

For example, the load of mobile device 730 can if mobile device 730 is the linear moving apparatus for including rotating electric machine To be torque.In order to which along the first X-axis cutting line XL1 and the second X-axis cutting line XL2 separating base plate S, mobile device 730 is mobile During second plate 760, the load of mobile device 730 may be will increase.Also, in substrate S by mobile dress of isolated time point Setting 730 load may reduce.

For separating base plate S, the load of the mobile device 730 of mobile second plate 760 can pressurize according to cutting wheel 225 In the plus-pressure of substrate S and it is different.For example, the depth of cut of cutting wheel 225 also can if the plus-pressure of cutting wheel 225 reduces Reduce and be difficult to separating base plate S, the load for the mobile device 730 that substrate S is measured when being separated will increase.On the contrary, cutting wheel When 225 plus-pressure increases, the depth of cut of cutting wheel 225 also be will increase, and the separation of substrate S becomes easy, therefore, substrate S The load of the mobile device 730 measured when being separated can reduce.

As a result, on the basis of the load of the mobile device 730 measured when separating base plate S, adjustable cutting wheel 225 applies In the plus-pressure of substrate S.

For example, cutting wheel 225 may be ground when the usage amount of Reusability cutting wheel 225 and cutting wheel 225 increases Damage.As cutting wheel 225 is worn, the diameter of cutting wheel 225 can become smaller, and the depth of cut of cutting wheel 225 also reduces.As a result, Cutting wheel 225 applies pressure to the plus-pressure of substrate S and reduces, therefore the load of the mobile device 730 measured in separating base plate S can It can will increase.In this case, the plus-pressure for being applied to substrate S by increasing cutting wheel 225, is worn in cutting wheel 225 In the case where can also maintain evenly the shape by cutting line for being formed in substrate S.Also, it is applied to increase cutting wheel 225 It is added on the plus-pressure of substrate S, wheel mobile module 230 can be further mobile to substrate S by cutting wheel 225.

Load measurement module 1100 is used to measure the load of the mobile device 730 when substrate S is separated.Control unit 1000 Cutting wheel 225 is adjusted on the basis of the load for the mobile device 730 that can be measured by load measurement module 1100 is applied to substrate S Plus-pressure.For this purpose, the plus-pressure that can carry out making to be applied to substrate S in advance changes and measures when substrate S is separated The experiment or simulation of the load of mobile device 730.By above-mentioned experiment or simulation, it can obtain and be stressed on according to cutting wheel 225 The relevant data of load variations of the mobile device 730 of the stressed variation of substrate S.

Also, the load of the mobile device 730 when appropriate separating base plate S can be preset as reference load.This benchmark is negative Lotus can be different according to the characteristic of the substrates S such as thickness, the material of substrate S.Thus, it is possible to by experiment or simulation, it can be pre- If according to multiple reference loads of the characteristic of substrate S.

Control unit 1000 compares the load and reference load of the mobile device 730 measured when substrate S is separated, thus It can determine whether the plus-pressure appropriate that whether pressurizes on substrate S.

If the load that substrate S is measured when being separated within the scope of reference load, control unit 1000 may determine that for Pressed plus-pressure needed for appropriate separating base plate S on substrate S.Also, if the load of measurement exceeds reference load range, control Unit 1000 processed is judged as the excessive or too small plus-pressure that pressed to substrate S.

If the load for the mobile device 730 that substrate S is measured when being separated is less than reference load, control unit 1000 is sentenced Break to be applied on substrate S and exceeding appropriate stressed plus-pressure, by control wheel mobile module 230 make cutting wheel 225 to Direction far from substrate S is mobile.Reduced as a result, by the plus-pressure that cutting wheel 225 is applied to substrate S, needed for separating base plate S The load of mobile device 730 increases.

Also, the load of the mobile device 730 measured when separating base plate S is more than reference load, then control unit 1000 It is judged as that is pressed on substrate S is less than appropriate stressed plus-pressure, by control wheel mobile module 230, so that cutting wheel 225 is mobile to substrate S.The plus-pressure that cutting wheel 225 is applied to substrate S as a result, increases, mobile device needed for separating base plate S 730 load can reduce.

As described above, adjustment is cut if the load of the mobile device 730 when separating base plate S exceeds reference load range The plus-pressure that wheel 225 is applied to substrate S is cut, the load of mobile device 730 is maintained within the scope of reference load.It moves as a result, Separating base plate S in the case that device 730 can be run in optimal criteria load range.And it is possible to prevent mobile device 730 Load be excessively increased or reduce.

Furthermore in the plus-pressure for being applied to substrate S according to the abrasion of cutting wheel 225 without simultaneously, with mobile device 730 Come control wheel mobile module 230, the plus-pressure of adjust automatically cutting wheel 225 on the basis of load.It is ground as a result, in cutting wheel 225 Cutting wheel 225 can also be steadily maintained to apply pressure to the degree of substrate S in the case where damage, thus, it is possible to be formed uniformly in substrate S Smooth cutting line.

In addition, when smaller because of the plus-pressure that the reasons such as bad of cutting wheel 225 are applied to substrate S, mobile device 730 it is negative Lotus is possible to be excessively increased.At this point, such case may be judged as the failure of cutter for substrate by control unit 1000, It is possible that interrupting the operation of cutter for substrate.

Also, it as shown in figure 23, behind the middle section of separating base plate S, is not removed with the dummy portions at row end after substrate S State, substrate S is transferred to the first cutter unit 200.At this point, under the action of the gas sprayed from the second plate 760, substrate It can be floated from the second plate 760.

Furthermore when substrate S is located at the second plate 760, substrate S is adsorbed by the second plate 760.At this point, the first cutting wheel model After the cutting wheel 225 of block 221 and the second cutting wheel module 222 is contacted with substrate S respectively, cutting wheel 225 is mobile to X-direction, The first X-axis cutting line XL1 and the second X-axis cutting line XL2 is formed in the dummy portions of substrate S as a result,.

Also, as shown in Figure 24 and Figure 25, the fixture 910 of illusory removal unit 900, which is moved to, is formed with the cutting of the first X-axis The dummy portions of the substrate S of line XL1 and the second X-axis cutting line XL2.Also, after fixture 910 holds the dummy portions of substrate S, rotation Turn or moves horizontally and remove dummy portions from substrate S.The fixture 910 for removing dummy portions restores to original position without hindering the The movement of the cutting wheel 225 of one cutting wheel model block 221 and the second cutting wheel module 222.

In addition, as shown in figure 26, passing through along the substrate S that the first X-axis cutting line XL1 and the second X-axis cutting line XL2 is separated The rotation of multiple belts 710 is transferred to the second cutter unit 300.

At this point, as shown in figure 27, the second transfer unit 700 and the second cutter unit 300 are arranged in sustained height, substrate S It can be transferred directly to the second cutter unit 300.At this point, substrate S is from second under the influence of the gas supplied from the second plate 760 Plate 760 floats.

Also, as shown in figure 34, as the first adsorption plate 430 and the second adsorption plate 440 rise, the absorption of substrate S and second Second adsorption nozzle 441 of plate 440 contacts.Also, as the first adsorption plate 430 and the second adsorption plate 440 continue to rise, substrate S is risen with the state for being contacted with the second adsorption nozzle 441 of the second adsorption plate 440.At this point, substrate S is to be inhaled by gravity by second Attached nozzle 441 is supported, therefore can also maintain the posture of substrate S even if not applying adsorption capacity in the second adsorption nozzle 441.

In addition, adsorption force is when the first adsorption nozzle 431 or the second adsorption nozzle 441, in order to by its strong adsorption force Degree increase to can appropriate sorbing substrate S size, need the scheduled time.In the present invention, the first suction within the predetermined time During the adsorption capacity of attached nozzle 431 or the second adsorption nozzle 441 is increased, substrate S can also be supported in by gravity One adsorption nozzle 431 or the second adsorption nozzle 441, to rise substrate S.Thus, it is possible to prevent from increasing in adsorption capacity intensity The phenomenon that can not rising substrate S and wait in a period of the intensity of appropriate sorbing substrate S.That is, it is possible to reduce Time needed for rising substrate S.

The 441 sorbing substrate S of the second adsorption nozzle of the second adsorption plate 440 during substrate S rises, then such as Figure 35 institute It states, the second adsorption plate 430 and the second adsorption plate 440 are rotated by adsorption plate rotating device 460.

Also, under as shown in figure 36, substrate S by the second adsorption nozzle 441 of the second adsorption plate 440 in the state of being adsorbed Drop.

Furthermore as shown in figure 37, when the second adsorption plate 430 is inserted into the space between belt 410, then substrate S is located at band 410 top of son is simultaneously separated from the second adsorption nozzle 441.In this state, the first adsorption plate 430 can be located at the second adsorption plate 440 lower section, so as to be immediately performed the movement of subsequent overturning substrate S, it is possible thereby to shorten the time needed for process.

In this state, as shown in figure 38, the substrate S of overturning is by the rotation of belt 410 from substrate roll-over unit 400 It is transferred to third cutter unit 500.Another example, liftable and the pickup unit moved horizontally setting (not shown) are overturn in substrate Between unit 400 and third cutter unit 500, for substrate S to be transferred to third cutter unit from substrate roll-over unit 400 500。

As shown in Figure 38 and Figure 39, third cutter unit 500 forms the second Y-axis cutting line in the second face S2 of substrate S YL2。

Third cutter unit 500 includes: third framework 510, extends to X-direction and can move to Y direction；Third Head 520 can movably be set to third framework 510 to X-direction and have cutting wheel 521；Third guiding rail 530, It is used to guide the movement of third framework 510；Belt 540 is used to support substrate S；Support plate 550, can be to Z-direction It is movably set to the lower section of belt 540, belt 540 and supporting substrate S are supported when cutting wheel 521 applies pressure to substrate S；Support Plate lifting device 560 increases in the Z-axis direction descending branch fagging 550.

Third framework 510 can have multiple third heads 520 in the X-axis direction.

Actuator, the basis of pneumatics or oil pressure operation are provided between third framework 510 and third guiding rail 530 The linear motor or ball screw device isoline mobile device of electromagnetic interaction operation.As a result, in cutting wheel 521 by substrate In the state of S pressure, third framework 510 is moved along third guiding rail 530 to Y direction, thus in the second face of substrate S S2 forms the second Y-axis cutting line YL2.

Belt 540 is supported by multiple belt wheels 541, and at least one of multiple belt wheels 541 can be to provide for rotating The driving pulley of the driving force of belt 540.Belt 540 is not separated into the one-piece type belt of multiple portions preferably, with equably Supporting substrate S integral face simultaneously transfers substrate.

The rotation of belt 540 and when moving substrate S mobile, support plate 550 is supported plate lifting device 560 and declines and separate Belt 540, so that belt 540 is smoothly moved in the case where not rubbing with support plate 550.Also, second is formed in substrate S When Y-axis cutting line YL2, support plate 550 is supported the bottom surface that plate lifting device 560 rises and supports belt 540, thus branch support group Plate S.For example, support plate 550 has the vacuum hole connecting with vacuum source, support plate 550 is adsorbed by the micropore on belt Substrate S.

During the second face S2 of substrate S forms the second Y-axis cutting line YL2, it is provided with the with cutting wheel 521 The third framework 510 on three heads 520 can move, and substrate S is supported plate 550 and is supported, therefore cutting wheel 521 can be with bigger Pressure pressing is in substrate S, thus substrate S easy to cut.

Also, substrate S is supported plate 550 and is supported, and there is no need for support the roller of cutting wheel 521.As a result, may be used It is the width on third head 520 corresponding to the space size of removal roller to reduce, thus, it is possible to shorten multiple third heads 520 recently abut when multiple third heads 520 cutting wheel 521 between interval.Pass through cutting wheel so as to shorten Interval between 520 the second Y-axis cutting line YL2 formed.

As the second face S2 in substrate S forms the second Y-axis cutting line YL2, substrate S can be along the first Y-axis cutting line YL1 and the second Y-axis cutting line YL2 separation.

As a result, after substrate S is cut, X-axis stepped part XS can be formed, has and is equivalent to the first Y-axis cutting line The width of YL2 and the second Y-axis cutting line YL2 distance spaced apart from each other in the X-axis direction, the X-axis stepped part XS can be formed There are wiring and/or the electrode etc. with wiring connection.

The substrate S cut can be transferred to third transfer unit from third cutter unit 500 by the rotation of belt 540 800。

As shown in Figure 40 and Figure 42, third transfer unit 800 includes: belt 810, for accommodating from third cutter unit The substrate S of 500 transmitting；Pickup model 820 is used to hold and transfer substrate S；Support frame 830 can be moved to Y direction Pickup model 820 is supported dynamicly；Mobile module 840 moves pickup model 820 along support frame 830；Module 850 is gone up and down, It is used for the mobile pickup model 820 of Z-direction.

Belt 810 is supported by multiple belt wheels 811, and at least one of multiple belt wheels 811 can be to provide for rotating The driving pulley of the driving force of belt 810.The belt 810 of third transfer unit 800 can be with the belt of third cutter unit 500 540 are formed with identical height, so that substrate S is from third cutter unit 500 to the horizontal transmitting of third transfer unit 800.

Mobile module 840 and lifting module 850 can be the actuator, mutual according to electromagnetism by pneumatics or oil pressure operation Act on the linear motor or ball screw device isoline mobile device of operation.

Pickup model 820 may include: multiple adsorption plates 821, be connect by vacuum line 861 with vacuum source 860；Plate is high Degree adjustment device 822, connect with multiple adsorption plates 821 respectively and goes up and down adsorption plate 821；Pressure sensor 823, respectively with Multiple adsorption plates 821 connect and measure the pressure in adsorption plate 821.

Plate height adjusting device 822 can allow user to manually adjust the height of multiple adsorption plates 821.Also, plate height Adjustment device 822 can be by pneumatics or oil pressure operation actuator, according to electromagnetic interaction operation linear motor or Ball screw device isoline mobile device, so that the highly automated adjustment of multiple adsorption plates 821.

Another example, multiple plate height adjusting devices 822 are not connected to multiple adsorption plates 821, but by two with Upper adsorption plate 821 specifies multiple groups of adsorption plate 821 as a group, and adjusts the height of each group of adsorption plate 821.

At this moment, control unit 1000 can according to the pressure change in the adsorption plate 821 measured by pressure sensor 823 come Plate height adjusting device 822 is controlled, to go up and down multiple adsorption plates 821.

When substrate S is transferred to the belt 810 of third transfer unit 800, then substrate S is picked the absorption of module 820, by picking up Modulus block 820 vertically moving and moving horizontally, and substrate S is transferred to subsequent handling.

In the process, need substrate S uniform adsorption in multiple adsorption plates 821 of pickup model 820.But because the Flatness variation, the multiple absorption of pickup model 820 of substrate S caused by the height change of the belt 810 of three transfer units 800 The upright position of plate 821 changes, and substrate S is possible to equably be adsorbed in multiple adsorption plates 821 of pickup model 820.? The non-uniform adsorption of substrate S in the state of multiple adsorption plates 821 pickup model 820 vertically and horizontally when, it is possible to occur Substrate S is detached from the problem of multiple adsorption plate 821.

As a result, in the third transfer unit 800 in the embodiment of the present invention, before the complete sorbing substrate S of pickup model 820 Pickup model 820 is gradually mobile to substrate S, the pressure in multiple adsorption plates 821 is measured by pressure sensor 823.

With pickup model 820 is gradually mobile to substrate S, substrate S is adsorbed the absorption of plate 821, flat as substrate S Spend uniform, multiple adsorption plates 821 upright position it is uniform when, when substrate S is adsorbed by multiple adsorption plates 821, multiple adsorption plates Pressure in 821 changes simultaneously.

But if the flatness of substrate S is uneven or the upright position of multiple adsorption plates 821 is uneven, only base A part of plate S is adsorbed by the partial adsorbates plate 821 in multiple adsorption plates 821, and the rest part of substrate S is not adsorbed in absorption Plate 821.At this point, the partial pressure in multiple adsorption plates 821 can generate variation, but the pressure of the adsorption plate 821 of unadsorbed substrate S It will not change.

It follows that existing between the unchanged adsorption plate 821 of the adsorption plate 821 and pressure of pressure change relative to substrate The relative height differential of S, by adjusting the height of the unchanged adsorption plate 821 of height or pressure of the adsorption plate 821 of pressure change Above-mentioned relative height differential can be eliminated.

According to the pressure of the multiple adsorption plates 821 measured by multiple pressure sensors 823, (pressure becomes control unit 1000 Change) plate height adjusting device 822 is controlled, it is so as to adjust the height or pressure of the adsorption plate 821 of pressure change unchanged The height of adsorption plate 821.

Thus, it is possible to the relative height differential relative to substrate S between multiple adsorption plates 821 be eliminated, so that substrate S's is whole Dignity can be adsorbed equably by multiple adsorption plates 821.

According to structure as described above, the integral face of substrate S can be adsorbed equably by multiple adsorption plates 821, therefore, base Plate S can be picked module 820 and steadily be transferred to subsequent handling.
