Keep it stable.
The pressing unit 200 includes a moving mechanism 290 for moving the display substrate 1 in the Y direction crossing the transfer line. In the following description, in the present example, the Y direction is orthogonal to the transport line. And the pressure bonding unit 200 is provided by the mounting member supply part 220, and is equipped with the ACF adhesion part 230 which adhere | attaches ACF to the mounting member 2 cut out by the punching mechanism mentioned later. The mounting member 2 to which the ACF is bonded is passed to the mounting portion 280. Then, the pressing unit 200 press-fits the mounting member 2 to the three sides of one long side and both short sides of the display substrate 1 moved in the Y direction by the moving mechanism 290 by ACF.

In addition, the main crimping unit 300 performs at least the main crimping operation of the mounting member 2 mounted on one long side and three short sides of the display substrate 1 moved in the Y direction by the moving mechanism 390. This is done at the timing at which the processing time for each side overlaps. The three main compression parts 320A, 320B and 320C have a main compression head having an upper blade and a lower blade. The upper blade and the lower blade are heated by a heater, and heat-pressurize the mounting member 2 to be connected to the display substrate 1.
In order to main-bond the mounting member 2 to the display board | substrate 1, it presses by the upper blade, supporting the display board 1 which pressed the mounting member 2 from the lower side to the lower blade. At this time, the protective sheet 340A is interposed between the mounting member 2 and the upper blade (see FIG. 8 to be described later). The ACF pressurized by the upper blade is heated at 190 ° C. for 5 seconds and thermally cured. When a certain number of crimping | bonding operations are performed, the protective sheet 340A is sent by the sheet | seat conveying mechanism, and the use part which abuts on an upper blade changes.
In the main compression unit 300, the main compression portions 320B and 320C which main-bond the mounting members 2 on the gate side pressed against both short sides of the display substrate 1 are oriented in the left and right directions (the directions in which the units are arranged). A moving mechanism for moving to) is needed. However, of the production time required for each unit, the long main compression operation of the longest production time can be performed at a timing at which the processing time for each side overlaps. Therefore, there is an advantage that the time (around time) required from the start of the process to the end can be shortened through the whole stroke.

The ACF adhesion device 440 adheres the ACF to the PCB 6 supplied from the PCB supply device 430. The transfer mounting apparatus 450 conveys the PCB 6 in which the adhesion of the ACF is completed to the main compression unit 460. And the main crimping | compression-bonding part 460 pressurizes and heats the PCB 6, and it connects with the mounting member 2 of several source side.
As described above, at least one of the ACF bonding portion 230, the pressing unit 200, the main pressing unit 300, and the PCB connection unit 400 performs the same processing on three sides of the display substrate 1, respectively. It has three processing mechanisms to perform. The display substrates to be moved when the two processing mechanisms of the three processing mechanisms intersect the conveying line and are processed on two opposite sides of the display substrate 1 arranged at the processing position, respectively. In accordance with the size of 1), two processing mechanisms are configured to be accessible or spaced apart from the display substrate 1.
As described above, ACF adhesion can also be performed on the display substrate 1 side. In this case, in order to make the above-mentioned ACF adhesion part 230 into a three side process, it can implement by arrange | positioning ACF adhesion part 230 in three sides of the arrangement position of the display substrate 1 without the mounting member supply part 220. FIG. This modification has the effect that a process change can be avoided when there is a track record prior to the ACF adhering to a glass substrate.
In addition, the mounting member supply part 220 and the ACF adhesion part 230 are arrange | positioned at the long side of the display board | substrate 1, and the ACF adhesion part 230 is arrange | positioned without the mounting member supply part 220 at the left and right short sides, It is also possible to set it as the structure which adheres and press-bonds ACF to the mounting member 2 (for example, COF) beforehand, and the short side can be set as the structure which mounts an IC chip etc. in a next process. In this case, in the structure which directly connects the micro IC chip which becomes difficult to recognize a positioning mark by adhering ACF to a circuit surface beforehand directly with the display board | substrate 1, it is effective in raising mounting precision.
As mentioned above, the movement apparatus is ACF adhesion part 230, the pressing unit 200, the main pressing unit 300, and PCB connection arrange | positioned along the conveyance line of the 1st direction in which the display board 1 is conveyed. The display substrate 1 is moved to the processing position of the direction which intersects a conveyance line with respect to at least any one apparatus of the unit 400, and the display substrate 1 is arrange | positioned at the processing position of at least one apparatus. . Thereby, the display board 1 in which at least any one of the ACF adhesion part 230, the pressing unit 200, the main pressing unit 300, and the PCB connection unit 400 was moved to the processing position by the moving apparatus. Predetermined processing can be performed at the timing at which the processing time for at least each of the sides overlaps.
As described above, according to the moving device in the FPD module assembly line 10, the display substrate 1 is moved in the Y direction to the pressing unit 200, the main pressing unit 300, and the PCB connection unit 400, respectively. The moving mechanisms 290, 390, 490 are provided. Therefore, the predetermined processing can be performed at the timing at which the processing time for at least each side of the display substrate 1 overlaps. At this time, since the process of rotating the display substrate 1 is unnecessary, the space of the device group can be reduced, and the line length of the entire assembly device of the FPD module can be shortened. In addition, the movement mechanisms 290, 390, and 490 may not necessarily move the display substrate 1 in the direction orthogonal to the transfer line.
And although the example which moved the display board | substrate 1 to the direction which cross | intersects a conveyance direction in the horizontal direction was demonstrated as a moving device of this example, it is also comprised so that the movement direction of the display board | substrate 1 may move to an up-down direction, Of course it is possible.

The drive output part 113 produces | generates a drive signal based on the cutting position by the 1st cutter blade 694A determined according to this image measurement, and outputs it to the 1st cutter blade drive mechanism 265A. The first cutter blade drive mechanism 265A rotates and horizontally moves the first cutter blade 694A based on the received drive signal when the corresponding mounting member 2 is in the imaging position.
Thereby, the 1st cutter blade 694A is arrange | positioned in the position along the length M of the edge part of the mounting member 2 in parallel with the front side of the conveyance direction of the corresponding mounting member 2. Then, the first cutter blade drive mechanism 265A lowers the first cutter blade 694A to cut the ACF 3a.
In addition, the drive output unit 113 is formed by the second cutter blade 694B stored in the storage unit when the corresponding mounting member 2 is disposed at the mounting / compression position (above the ACF guide 696). Extract the cutting position. Then, a drive signal is generated based on the extracted cutting position, and output to the second cutter blade drive mechanism 265B. The second cutter blade drive mechanism 265B rotates and horizontally moves the second cutter blade 694B based on the received drive signal.
Thereby, the 2nd cutter blade 694B is arrange | positioned in the position along the length M of the edge part of the mounting member 2 in parallel with the side of the back side of the conveyance direction of the corresponding mounting member 2. Then, the second cutter blade drive mechanism 265B lowers the second cutter blade 694B to cut the ACF 3a. As a result, the ACF 3a can be cut to a length along the corresponding mounting member 2, and the ACF 3a can be bonded to the mounting member 2 with high accuracy.
And the imaging part which concerns on this invention is not limited to the 1st imaging camera 626 which has a binocular lens, For example, it can also be comprised by two imaging cameras and a prism. In this case, one imaging camera picks up the imaging area T1 through a prism, and the other imaging camera picks up the imaging area T2 through a prism. In addition, when changing the position of imaging area T1, T2 according to the kind of mounting member, it can respond by fixing two imaging cameras, moving a prism, or fixing two prisms and moving two imaging cameras.
Thus, the ACF adhesion block 670 picks up the edge part of the mounting member 2 with the 1st imaging camera 626, performs an image measurement, and determines the cutting position of the ACF 3a based on the result. As a result, ACF 3a can be cut | disconnected to the length according to the individual difference of the mounting member 2, and it can be made to adhere | attach with the corresponding mounting member 2 with high precision.
In addition, although the ACF adhesive block 670 used two cutter blades as a cutting part, one cutter blade which concerns on this invention may be sufficient. In that case, two cutting positions of the ACF 3a with respect to the mounting member 2 are cut by one cutter blade.
Moreover, in the ACF adhesive block 670 which concerns on embodiment mentioned above, although the half cut of the ACF tape 3 was demonstrated, the example which adhere | attached the half cut ACF 3a to the mounting member 2 was demonstrated. After the ACF 3a is attached to the member 2, the ACF tape 3 may be half cut.

[Main compression apparatus]
Next, a configuration example of the main crimping unit 300 will be described.
First, the structural example of the conventional main crimping apparatus is demonstrated.
The crimping apparatus used at the crimping process is equipped with the crimping head which presses a mounting member to a display substrate. When the pressing face (upper blade) of the pressing head is brought into direct contact with the mounting member, the ACF interposed between the mounting member and the display substrate is protruded and adhered to the pressing face, thereby degrading the flatness of the pressing face. Thereby, the pressing force which acts on a mounting member becomes nonuniform, and it becomes easy to produce a crimping | compression-bonding.
Therefore, the technique of interposing a protective sheet between the crimping surface of a crimping head and a mounting member so that the protruding ACF will not adhere to the crimping surface of a crimping head is considered. Since the protective sheet deteriorates under the influence of the heat of the crimping head and the pressing force, the protective sheet is sent by the transfer mechanism at a predetermined number of times or for a predetermined time and the use portion is changed.
[Main compression unit]
Here, the sheet conveyance mechanism of the main crimping unit 300 according to the first embodiment of the present invention will be described with reference to FIGS. 8 to 10. 8 is a cross-sectional view of the main compression unit 300. FIG. 9: is explanatory drawing which showed a part of sheet conveyance mechanism 350A regarding the main crimping unit 300 shown in FIG. FIG. 10: is explanatory drawing which showed the inclination changing part of the sheet conveying mechanism which concerns on the main crimping unit 300 shown in FIG.
The main crimping unit 300 has main crimping portions 320A, 320B and 320C.
The main crimping section 320A includes a lower frame 321A, an upper frame 322A, a crimping head 330A, a protective sheet 340A, and a sheet conveying mechanism 350A.
On the lower frame 321A, a lower blade (not shown) is provided. The lower blade is heated by a heater unit (not shown), and the tip portion is kept at 60 ° C to 100 ° C. The temperature of the tip portion of the lower blade is appropriately set according to the characteristics of the ACF to be used. Moreover, on the lower frame 321A, the upper frame 322A is provided so that it may pass over a lower blade. The upper frame 322A is provided with a lifting mechanism for moving the pressing head 330A in the vertical direction.
The crimping head 330A has an air spring structure using an air cylinder. A plurality of upper blade frames (not shown) are attached to the pressure rod of the air cylinder, and the upper blades 331 are fixed to these upper blade frames, respectively. The upper edge 331 is heated by the heater unit which is not shown in figure, and the front-end | tip part which has a crimping surface is kept at 150 degreeC-350 degreeC, for example. The crimping surface of each upper blade 331 is formed in substantially rectangular shape. The plurality of upper blades 331 attached to the plurality of upper blade frames are aligned in a straight line such that the short sides thereof face each other.
A protective sheet 340A is interposed between the upper blade 331 and the lower blade. This protective sheet 340A is formed in the band shape which has a predetermined | prescribed width, and is sent out between the upper blade 331 and the lower blade by 350A of sheet conveying mechanisms.
350 A of sheet feed mechanisms are provided with the sheet feed reel 351, the rotation drive part 352, the guide roller group 353A, and the sheet collection | recovery part 354. As shown in FIG.
340A of unused protective sheets are wound up by the sheet supply reel 351, and 340A of used protection sheets are collect | recovered by the sheet collection | recovery part 354. The rotation drive part 352 drives intermittently and rotates the sheet feed reel 351 intermittently. When the sheet feed reel 351 rotates, the protective sheet 340A is fed out by a predetermined transfer amount at a predetermined transfer speed.
The sheet recovery part 354 recovers the protective sheet 340A by a predetermined amount of transfer in synchronization with driving of the rotation driving part 352. As this sheet collection | recovery part 354, it can comprise with the rotation drive part which rotates a collection reel and a recovery reel, for example. Moreover, the suction device which sucks the protective sheet 340A may be sufficient.
The guide roller group 353A changes the advancing direction of the protective sheet 340A, and guides the protective sheet 340A from the sheet supply reel 351 to the sheet recovery part 354. The guide roller group 353A includes guide rollers 353a and 353b disposed on the side of the lower blade. The protective sheet 340A sent out from the sheet feed reel 351 is changed by the guide rollers not shown in the guide roller group 353A, and guided to the guide roller 353a.
The rotation axis of the guide roller 353a is inclined with respect to the direction orthogonal to the direction in which the plurality of upper blades 331 are arranged in parallel in the horizontal direction, and is directed toward the front of the main crimping portion 320A, so that the upper blade 331 ) The guide roller 353A guides the protective sheet 340A between the upper blade 331 of the crimping head 330A and the lower blade provided on the lower frame 321A, and the plurality of upper blades 331 are arranged. Inclined in the horizontal direction with respect to the defined direction. This inclination angle is demonstrated next with reference to FIGS. 11-16.
In addition, 350 A of sheet conveying mechanisms are provided with the inclination change part 355 which changes the inclination direction of the protective sheet 340A arrange | positioned between the upper blade 331 and the lower blade. This inclination change part 355 is comprised from two press rollers 355a and 355b and the taper roller 355c (refer FIG. 9).
The pressure rollers 355a and 355b are formed in a cylindrical shape, and are pressed so that the protection sheet 340A which opposes the upper blade 331 may not displace upward. Thereby, the protection sheet 340A which opposes the upper edge 331 is maintaining the state substantially parallel to a horizontal direction. The rotating shafts of the pressure rollers 355a and 355b are substantially orthogonal to the width direction of the protective sheet 340A.
The pressure rollers 355a and 355b are not limited to a cylindrical shape, but a tapered roller whose diameter increases as the front of the main compression section 320A may be used.
The taper roller 355c is arrange | positioned above the press roller 355a, 355b. The rotation axis of this taper roller 355c is oriented in the direction orthogonal to the direction in which the upper blade 331 is arranged. And the taper roller 355c is continuously made small in diameter as it goes to the front of main compression part 320A.
These press rollers 355a and 355b and the taper roller 355c reverse the inclination angle of the protective sheet 340A guided by the guide roller 353a. Therefore, as for the protection sheet 340A from the guide roller 353a to the pressure roller 355a, and the protection sheet 340A from the pressure roller 355b to the guide roller 353b, the several upper edge 331 is It is symmetrical with respect to the plane orthogonal to the arranged direction (see FIG. 8).
Thereby, the part which inclines in a horizontal direction with respect to the direction in which the some upper blade 331 of the protective sheet 340A was arranged can be shortened. Therefore, the amount of protrusion to the front of the protective sheet 340A and the guide roller 353b can be suppressed, and the apparatus can be miniaturized.
In addition, since the main crimping unit 300 performs the crimping operation of the mounting member 2 (see FIG. 1) mounted on the three sides of the display substrate 1 at a timing at which the processing time for at least each side overlaps, Three main compression parts 320A, 320B, and 320C are provided. Therefore, by suppressing the amount of protrusion of the protective sheet 340A and the guide roller 353b to the front, it is possible to prevent the protective sheet 340A and the guide roller 353b from interfering with the main compression portions 320B and 320C. .
The guide rollers 353b and 353c change the advancing direction of the protective sheet 340A which has passed between the upper blade 331 and the lower blade, and guide the sheet recovery part 354. Thereby, the protective sheet 340A which passed the guide rollers 353b and 353c is collect | recovered by the sheet collection | recovery part 354.
The main crimping portions 320B and 320C are disposed in front of the main crimping portion 320A, and the crimping heads 330B and 330C face each other. These main crimping parts 320B and 320C have the same configuration as the main crimping part 320A. The main compression parts 320B and 320C differ from the main compression parts 320A in that the sheet conveying mechanisms 350B and 350C have an inclination change part.
The main crimping section 320B includes a lower frame 321B, an upper frame 322B, a crimping head 330B, a protective sheet 340B, and a sheet conveying mechanism 350B.
The sheet conveying mechanism 350B has a sheet feeding reel 351, a rotation driving unit 352, a guide roller group 353B, and a sheet collecting unit 354.
An unused protective sheet 340B is wound around the sheet supply reel 351 of the main crimping section 320B, and the used protective sheet 340B is collected in the sheet recovery section 354. When the sheet feed reel 351 rotates by the rotation drive part 352, the protective sheet 340B is sent out by a predetermined | prescribed conveyance amount at a predetermined | prescribed transmission speed.
The guide roller group 353B changes the advancing direction of the protective sheet 340B, and guides the protective sheet 340B from the sheet supply reel 351 to the sheet recovery part 354. The guide roller group 353B includes guide rollers 353d and 353e disposed on the side of the lower blade. The protective sheet 340B sent out from the sheet feed reel 351 is changed in the traveling direction by guide rollers not shown in the guide roller group 353B, and guided to the guide roller 353d.
The guide roller 353d guides the protective sheet 340B between the upper blade 331 of the crimping head 330B and the lower blade (not shown) provided in the lower frame 321B, and the upper blade 331. It is inclined in the horizontal direction with respect to this arranged direction. The protection sheet 340B which has passed between the upper blade 331 and the lower blade is changed in the traveling direction by the guide roller 353e and a guide roller (not shown), and proceeds toward the sheet recovery part 354. .
The main compression section 320C includes a lower frame 321C, an upper frame 322C, a compression head 330C, a protective sheet 340C, and a sheet conveying mechanism 350C.
The sheet conveying mechanism 350C has a sheet feeding reel 351, a rotation driving unit 352, a guide roller group 353C, and a sheet collecting unit 354.
340C of unused protective sheet is wound up by the sheet supply reel 351 of this crimping | compression-bonding part 320C, and 340C of used protection sheet is collect | recovered by the sheet collection | recovery part 354. When the sheet supply reel 351 rotates by the rotation drive part 352, the protective sheet 340C is sent out by the predetermined | prescribed conveyance amount by a predetermined | prescribed transmission speed.
The guide roller group 353C changes the advancing direction of the protective sheet 340C, and guides the protective sheet 340C from the sheet supply reel 351 to the sheet recovery part 354. The guide roller group 353C includes guide rollers 353f and 353g disposed on the side of the lower blade. The protective sheet 340C sent out from the sheet feed reel 351 is changed by the guide rollers not shown in the guide roller group 353C, and guided to the guide roller 353f.
The guide roller 353f guides the protective sheet 340C between the upper blade 331 of the crimping head 330C and the lower blade (not shown) provided in the lower frame 321C, and the upper blade 331. It is inclined in the horizontal direction with respect to this arranged direction. The protection sheet 340C which has passed between the upper blade 331 and the lower blade changes the direction of travel by the guide roller 353g and a guide roller (not shown), and proceeds toward the sheet recovery part 354. .
As the material of the protective sheets 340A, 340B, and 340C, for example, polytetrafluoroethylene, silicone rubber, polyimide, and the like can be applied. Moreover, it can also form with the composite sheet which laminated | stacked two or more types of these materials. Polytetrafluoroethylene is very suitable as a material to which ACF does not adhere easily, and silicone rubber is preferable as a material which has cushioning property. Moreover, polyimide is preferable as a material with favorable heat resistance.
[Inclination angle and feed amount of the protective sheet]
Next, the inclination angle and the feed amount of the protective sheet will be described with reference to FIGS. 11 to 16.
11-16 is explanatory drawing which showed the 1st-6th example of the inclination-angle and the feed amount of the protective sheet with respect to the FPD module assembly line 10. FIG.
In the sheet conveying mechanisms 350A, 350B and 350C of the FPD module assembly line 10, the protective sheets 340A, 340B and 340C are sent until the used part is out of the upper blade 331. When the inclination angle θ of the protective sheet with respect to the direction in which the plurality of upper blades 331 is arranged is small, the amount of the protective sheet protruding toward the front of the crimping head can be reduced, and the device can be miniaturized. . Therefore, in this embodiment, inclination angle ( theta) of a protective sheet is determined in consideration of said two points.
Here, the direction in which the plurality of upper blades 331 are arranged is referred to as the X direction, and the direction orthogonal to the direction in which the plurality of the upper blades 331 is arranged is referred to as the Y direction. The length in the X direction (the length of the upper blade) of the upper blade 331 is referred to as L, and the interval (the distance between the upper blades) of the adjacent upper blade 331 is referred to as L1. In addition, the length (width of an upper blade) of the upper edge 331 of Y direction is called t.
In that case, the inclination angle θ of the protective sheet is determined by the following equation.
tan θ = t / (L + L1)
In the first example shown in FIG. 11, the distance L1 between the upper blades is shorter than the length L of the upper blades (L> L1). And the shorter the distance L1 between upper blades, the closer tan θ becomes to t / L [t / (L + L1) _t / L].
The feed amount in the X direction of the protective sheet in the first example is the same as the length obtained by adding the distance L1 between the length L of the upper blade and the upper blade, and the feed amount in the Y direction is equal to the width t of the upper blade.
Thereby, the length of the width direction of a protective sheet can be set short. Moreover, many used parts can be arrange | positioned on a protective sheet, and the use efficiency of a protective sheet can be improved. And when it is set as the said conveyance amount, the used part (indentation) on a protective sheet is arrange | positioned in the Y direction (direction orthogonal to the direction in which the several upper blades 331 were arrange | positioned). In addition, the used part of the protective sheet arrange | positioned in the Y direction is used by the different upper blade 331, respectively.
In the second example shown in FIG. 12, the distance L1 between the upper blades is longer than the length L of the upper blades (L <L1). The distance L1 between the upper blades is twice the length L of the upper blades. therefore,
tan θ = t / 3L
.
The feed amount in the X direction of the protective sheet in the second example is 1/3 of the length obtained by adding the distance L1 between the upper edges to the length L of the upper edges. Namely, the length L of the upper blade is made equal. On the other hand, the feed amount in the Y direction is 1/3 of the width t of the upper blade.
Thereby, the length of the width direction of a protective sheet can be set short. Moreover, many used parts can be arrange | positioned on a protective sheet, and the use efficiency of a protective sheet can be improved. And when it is said transfer amount, the used part on a protective sheet is arrange | positioned in a Y direction, and these used part are used by the different upper blade 331, respectively.
In the third example shown in FIG. 13, the distance L1 between the upper edges is approximately equal to the length L of the upper edges (L = L1). therefore,
tan θ = t / 2L
.
The feeding amount in the X direction of the protective sheet in the third example is 1/2 of the length obtained by adding the distance L1 between the upper edges to the length L of the upper edges. Namely, the length L of the upper blade is made equal. On the other hand, the feed amount in the Y direction is 1/2 of the width t of the upper blade.
Thereby, the length of the width direction of a protective sheet can be set short. Moreover, many used parts can be arrange | positioned on a protective sheet, and the use efficiency of a protective sheet can be improved. And when it is said transfer amount, the used part on a protective sheet is arrange | positioned in a Y direction, and these used part are used by the different upper blade 331, respectively.
In the fourth example shown in Fig. 14, the intervals of the used portions adjacent to the Y direction are α so that the used portions arranged in the Y direction are not in contact with each other. therefore,
tan θ = (t + α) / (L + L1)
.
In this fourth example, the distance L1 between the upper blades is longer than the length L of the upper blades (L <L1). Specifically, the distance L1 between the upper blades is a length obtained by adding β to a length twice the length L of the upper blades. therefore,
L + L1 = 3L + β
.
Here, 3L + β = 3L ', and t + α is t'. As a result,
tan θ = t '/ 3L'
.
The feed amount in the X direction of the protective sheet in the fourth example is 1/3 of the length obtained by adding the distance L1 between the upper edges to the length L of the upper edges. In other words, the feed amount in the X direction is set to L '/ 3. On the other hand, the feed amount in the Y direction is 1/3 of the length obtained by adding α to the width t of the upper blade. In other words, the feed amount in the Y direction is t '/ 3.
Thereby, many used parts can be arrange | positioned on a protective sheet, and the use efficiency of a protective sheet can be improved. And when it is said transfer amount, the used part on a protective sheet is arrange | positioned in a Y direction, and these used part are used by the different upper blade 331, respectively.
In the fifth example shown in FIG. 15, similarly to the fourth example, the interval between the used portions adjacent to the Y-direction is α. therefore,
tan θ = (t + α) / (L + L1)
.
In this fifth example, the distance L1 between the upper blades is longer than the length L of the upper blades (L <L1). Specifically, the distance L1 between the upper blades is the length obtained by adding β to the length L of the upper blades. therefore,
L + L1 = 2L + β
.
Here, 2L + β = 2L ', and t + α is t'. As a result,
tan θ = t '/ 2L'
.
The feed amount in the X direction of the protective sheet in the fifth example is set to 1/2 of the length L of the upper blade plus the distance L1 between the upper blades. That is, let the feed amount in the X direction be L '/ 2. On the other hand, the feed amount in the Y direction is 1/2 of the length of α added to the width t of the upper blade. In other words, the feed amount in the Y direction is t '/ 2.
Thereby, many used parts can be arrange | positioned on a protective sheet, and the use efficiency of a protective sheet can be improved to a protective sheet. And when it is said transfer amount, the used part on a protective sheet is arrange | positioned in a Y direction, and these used part are used by the different upper blade 331, respectively.
In the sixth example shown in FIG. 16, the distance L1 between the upper blades is shorter than the length L of the upper blades (L> L1). When the distance L1 between upper edges is shorter than the length L of an upper edge, the inclination-angle ( theta) of a protective sheet can be determined by following Formula.
tan θ = (t + α) / n (L + L1)
However, n is a positive integer (n) (n≥1).
Thereby, the inclination angle ( theta) of a protective sheet can be made small. That is, when n is made large, the inclination angle θ can be set small. Therefore, determining the inclination angle θ of the protective sheet by this equation is effective when the amount of the protective sheet protruding forward of the crimping head is limited. And as n increases, the use efficiency of a protective sheet becomes low, What is necessary is just to determine the value of n in consideration of the quantity which a protective sheet protrudes in front of a crimping head, and the use efficiency of a protective sheet.
In the sixth example, n = 2. In this case, the feed amount in the X direction of the protective sheet is made twice the length L of the upper blade plus the distance L1 between the upper blades. That is, let the feed amount in the X direction be 2 (L + L1). On the other hand, the feed amount in the Y direction is the length obtained by adding α to the width t of the upper blade. In other words, the feed amount in the Y direction is t + α.
And as shown in FIG. 8, in the main crimping | compression-bonding part 320A of this embodiment, the inclination-change part 355 changes the inclination-angle of the protective sheet 340A. Therefore, in the protection sheet 340A on the downstream side (the sheet collection | recovery part 354 side) rather than the inclination change part 355, the upper edge 331 is in contact with the used part. Therefore, in the main crimping portion 320A, the number of times of use of the protective sheet 340A on the upstream side (the sheet feed reel 351 side) of the inclination change portion 355 is half the allowable number.
The number of uses described above is the number of times the upper blade 331 abuts on the same portion of the protective sheet 340A. In addition, a permissible number of times is an upper limit of the number of times which may make the upper edge 331 contact the same part of 340 A of protective sheets. This allowable number of times can be appropriately set in consideration of the material of the protective sheet, the temperature of the upper blade, and the like.
For example, when using the protection sheet which can carry out a crimping operation up to 10 times in the same part, when a crimping operation is performed 5 times upstream from the inclination change part 355, a protection sheet is sent only by a predetermined | prescribed feed amount. Thereby, even if the upper blade 331 contacts the used part on the downstream side than the inclination change part 355, the number of uses does not exceed the permissible number.
[Modified example of the crimp part of the main crimping unit]
It is explanatory drawing which shows the modification of the crimping | compression-bonding part of this crimping unit which concerns on 1st Embodiment of the assembly apparatus of the FPD module of this invention. In this modification, the structure of the sheet | seat feed mechanism shown in FIG. 8 is made different from 1st Embodiment. That is, by having two sheet conveying mechanisms, it has two sets of a protective sheet and a sheet conveying mechanism. And since the protection sheet is not used twice at the left and right crimping part with the inclination change part as a boundary, there exists an effect that there is no possibility that a protective sheet may be cut off in the middle.
The main crimping unit according to the first embodiment of the assembling apparatus of the FPD module has the crimping portions 620A, 320B, and 320C. That is, the main compression parts 320B and 320C are the same as those used for the main compression unit 300 according to the first embodiment.
As shown in FIG. 17, the crimping | compression-bonding part 620A has the upper frame 622A, two protective sheets 640A and 640B, and two sheet conveyance mechanisms 650A and 650B. That is, the crimping | compression-bonding part 620A has two sets of the protective sheet and the sheet | seat conveying mechanism. Moreover, the crimping | compression-bonding part 620A is equipped with the lower frame and a crimping head (not shown).
The upper frame 622A is formed in a substantially C-shape as viewed from the front, and has a rectangular upper plate 628 and side plates 629A and 629B that are respectively continuous on the short sides of the upper plate 628. The side plates 629A and 629B are each formed in a rectangular shape that is long in the vertical direction, and one short side thereof is continuous to the upper plate 628.
On the long side of one side (front side) of the upper plate 628, cutouts 625a and 625b for avoiding interference with the protective sheets 640A and 640B are formed. Similarly, notches 626a and 627a are formed on the long side of one side (front side) of the side plates 629A and 629B to avoid interference with the protective sheets 640A and 640B.
The two protective sheets 640A and 640B are each formed in a band shape having a predetermined width, and are interposed between the upper blade and the lower blade. And when performing a crimping | compression-bonding operation, it interposes between the upper blade and the mounting member 2 (refer FIG. 1). The part interposed between the upper blade and the lower blade of these protective sheets 640A and 640B is located on the same plane.
The protective sheet 640A is formed in a band shape having a predetermined width, and is disposed between the upper blade and the lower blade on the side plate 629A side than the middle portion of the upper frame 622A by the sheet conveying mechanism 650A. It is sent out. On the other hand, the protective sheet 640B is formed in a band shape having a predetermined width similar to that of the protective sheet 640A, and is side plate 629A side from the middle portion of the upper frame 622A by the sheet conveying mechanism 650B. It is sent out between the upper blade and the lower blade of.
The sheet conveying mechanism 650A includes a sheet feed reel and a rotation drive unit (not shown), a guide roller group 653A, and a sheet collecting unit 655A.
The guide roller group 653A guides the protective sheet 640A from the sheet feed reel to the sheet recovery part 655A. This guide roller group 653A includes guide rollers 653a and 653b arranged at predetermined intervals in a direction in which a plurality of upper blades (not shown) are arranged. The guide roller 653a is arrange | positioned at the side plate 629A side in 622A of upper frames, and the guide roller 653b is arrange | positioned at the intermediate part in 622A of upper frames.
The protective sheet 640A sent out from the sheet feed reel penetrates through the cutout portion 626a of the side plate 629A and reaches the guide roller 653a. The guide roller 653a guides the protective sheet 640A between the upper blade and the lower blade, and inclines the horizontal direction with respect to the direction in which the plurality of upper blades are arranged.
The guide roller 653b guides the protective sheet 640A which has passed between the upper blade and the lower blade upward, and guides the sheet recovery part 655A. As a result, the protective sheet 640A is recovered through the cutout portion 625a of the upper frame 622A to the sheet recovery portion 655A.
The sheet conveying mechanism 650B has the same structure as the sheet conveying mechanism 650A, and is provided with the sheet feed reel and rotation drive part which are not shown in figure, the guide roller group 653B, and the sheet collection | recovery part 655B. .
The guide roller group 653B guides the protective sheet 640B from the sheet feed reel to the sheet recovery part 655B. This guide roller group 653B includes guide rollers 653c and 653d arranged at predetermined intervals in a direction in which a plurality of upper blades (not shown) are arranged. The guide roller 653c is arrange | positioned at the side plate 629B side in 622A of upper frames, and the guide roller 653d is arrange | positioned at the intermediate part in 622A of upper frames.
The protective sheet 640B sent out from the sheet feeding reel penetrates through the cutout 627a of the side plate 629B and reaches the guide roller 653c. The guide roller 653c guides the protective sheet 640B between the upper blade and the lower blade, and inclines in the horizontal direction with respect to the direction in which the plurality of upper blades are arranged.
The guide roller 653d guides the protective sheet 640B which has passed between the upper blade and the lower blade upward, and guides the sheet recovery part 655B. Thereby, the protective sheet 640B is recovered by the sheet recovery part 655B through the notch 625b of the upper frame 622A.
Thus, in this embodiment, it was set as the structure which provides two sets of the pair of a protective sheet and a sheet | seat feed mechanism with respect to the crimping head of the crimping | compression-bonding part 620A. Thereby, the protrusion amount of the protection sheet to the front can be made smaller with respect to the crimping head of the crimping | compression-bonding part 620A compared with the case where a protective sheet and a sheet feed mechanism are provided in one set. As a result, the device can be miniaturized. In addition, by reducing the amount of protrusion of the protective sheet toward the front, the protective sheet can be prevented from interfering with the main compression parts 320B and 320C (see FIG. 8).
Moreover, since the other upper blade 331 does not contact the used part deviating from the contact position of the upper blade 331, the crimping operation | work more stable than the main crimping | compression-bonding part 320A which concerns on 1st Embodiment can be performed.
And in the modified example of 1st Embodiment, although the pair of the protective sheet and the sheet | seat feed mechanism was provided with two sets of the crimping head of the crimping | compression-bonding part 620A, the pair of the protective sheet and the sheet | seat feed mechanism which concerns on this invention are 3 It can be more than a trillion.
According to a modification including the first embodiment described above, the protective sheet is guided between the plurality of upper blades of the crimping head and the mounting member (lower blade), and inclined in the horizontal direction with respect to the direction in which the plurality of upper blades are arranged. do. When the protective sheet is sent by the sheet conveying mechanism, the used portion caused by the upper edge contacting is inclinedly displaced with respect to the upper edge. Therefore, the amount of displacement of the protective sheet from the crimping point by the upper blade to the end of the used portion can be reduced. As a result, the conveyance amount of a protective sheet can be made small and a conveyance time can be shortened. Moreover, even if the displacement amount of a protective sheet becomes small, a used part can be removed from a crimping | compression-bonding point.
In addition, since the transfer mechanism can be arranged on the side of the crimping head, the device can be miniaturized and heat can be prevented from increasing around the crimping head. That is, in the above-described first embodiment, the protective sheet can be transferred in a short time while realizing miniaturization of the apparatus. Moreover, by adjusting the conveyance amount of a protective sheet, many used parts can be arranged on a protective sheet, and the use efficiency of a protective sheet can be improved.
In the modification including the above-described first embodiment, the mounting time of the mounting member 2 to which the ACF is bonded is set so that the processing time for each side overlaps with three sides of the display substrate 1. Therefore, the scale can be reduced as compared with the FPD module assembly line which processes two sides of the display substrate conventionally used.
In the modified example including the first embodiment described above, an example in which two rows of ACFs are bonded at the same time is shown. However, depending on the type of COF to be mounted, only one side of the ACF may be bonded. It is not limited to bonding the.

[Operation of Drawer Carrier]
Next, operation | movement of the drawer conveyance part 520 is demonstrated with reference to FIG. 20 and FIG. 20 is an explanatory diagram showing the operation of the withdrawal and transfer unit 520 in the transfer unit 500. 21 is a timing chart showing the operation of the take-out and transport unit 520.
FIG. 20A is an explanatory view of a state in which the holding unit 531 of the lead-out transport unit 520 is in contact with the flat part facing upward of the display substrate 1, and shows a timing t1 state shown in FIG. 21. have.
In the state shown in FIG. 20A, the holding portion 531 contacts the flat portion of the display substrate 1A at the working position of the main compression unit 300, and holds the holding portion at the substrate holding arm 535. 543 contacts the planar portion of the display substrate 1B on the center mounting table 570 (see FIG. 19). The position of the 1st direction X of the support part 536 and the position of the 2nd direction Z in the board | substrate support member 521 at this time are made into zero.
In addition, the rotation angle ( theta) 1 of the holding | maintenance part 531 with respect to the arm part 533 at this time is -35 degrees. The rotation angle θ 1 is an angle when the rotation range of the holding portion 531 is set to 70 ° and the middle thereof is set to 0 °. Therefore, the holding part 531 rotates from -35 degrees to 35 degrees.
In addition, the rotation angle ( theta) 2 of the arm part 533 with respect to the support part 536 is 35 degrees.
The rotation angle θ 2 is an angle when the rotation range of the arm portion 533 is set to 70 ° and the middle thereof is set to 0 °. Therefore, the arm part 533 rotates from 35 degrees to -35 degrees, and the rotation directions of the arm part 533 and the holding part 531 are reversed.
When the holding portions 531 and 543 come into contact with the planar portions of the display substrates 1A and 1B, the holding portions 531 are attracted by the adsorption portion of the holding substrate 531 and by the adsorption portion of the holding portion 543. Adsorption of the display substrate 1B is started (refer FIG. 21). When the predetermined time elapses, the holding units 531 and 543 adsorb and hold the display substrates 1A and 1B.
Thereafter, the lifting unit 537 (see FIG. 19) is driven, and the supporting unit 536 moves (rises) by a predetermined distance (60 mm in this example) in the second direction Z. As shown in FIG. As a result, the holding portions 531 and 543 holding the display substrates 1A and 1B move (raise) by the predetermined distance in the second direction Z together with the supporting portion 536. This state is a state of timing t1 shown in FIG.
In addition, although the operation | movement of the supply conveyance part 510 is abbreviate | omitted in FIG. 20, the operation | movement of the supply conveyance part 510 and the drawing conveyance part 520 is synchronizing with the operation | movement of the supply conveyance part 510. As shown in FIG. When the holding parts 531 and 543 holding the display substrates 1A and 1B start the movement in the second direction Z, the supply conveying part 510 holds holding the display substrate 1 (not shown). The unit 511 is moved in the third direction Y toward the working position of the main compression unit 300.
When the movement of the holding portions 531 and 543 holding the display substrates 1A and 1B to the second direction Z is completed, the second rotation driving part 534 (see FIG. 19) moves the arm portion 533 to the R1 direction (FIG. 20 (B)] is rotated at a predetermined speed. Further, the first rotation drive unit 532 (see FIG. 19) rotates the holding unit 531 at a predetermined speed, such as the arm portion 533, in the R2 direction opposite to the R1 direction. In addition, the slider 552 moves the substrate support member 521 to the downstream side in the first direction X. FIG.
At this time, the movement speed of the substrate support member 521 is equal to the speed at which the rotation shaft 532a of the holding portion 531 displaces upstream in the first direction X with respect to the rotation shaft 534a of the arm portion 533. Doing. Therefore, the rotation shaft 532a of the holding part 531 moves in the third direction Y and is spaced apart from the working position of the main compression unit 300.
As a result, the holding part 531 can be moved to the 3rd direction Y without using the linear drive shaft which guides the movement of the holding part 531 to the 3rd direction Y. As shown in FIG. Therefore, it is not necessary to secure a space for evacuating the linear drive shaft which guides the movement of the holding part 531 in the third direction Y until it does not interfere with the work unit. Thereby, the space for arranging the conveying unit 500 can be made small, and the whole apparatus can be miniaturized.
In addition, in order for the holding part 531 to rotate at the predetermined speed | rate similar to the arm part 533 in the R2 direction, the display substrate 1A moves without rotating with respect to the main crimping unit 300. As shown in FIG. Thereby, since the attitude | position of the display substrate 1A with respect to the main crimping unit 300 can always be made constant, the display board 1A does not interfere with the main crimping unit 300.
FIG. 20B is an explanatory diagram of a state in which the rotation angles θ 1 and θ 2 of the arm portion 533 and the holding portion 531 are 0 °, and show a timing t2 state shown in FIG. 21.
In the state shown in FIG. 20B, the rotation shaft 532a of the holding portion 531 and the rotation shaft 534a of the arm portion 533 coincide with a straight line L parallel to the first direction X. In FIG. Until the state shown in FIG. 20B is reached, the rotating shaft 532a is displaced to the upstream side in the first direction X with respect to the rotating shaft 534a. Therefore, the slider 552 (see FIG. 19) moves the substrate support member 521 in the first direction until the rotational axis 532a and the rotational axis 534a coincide with a straight line L parallel to the first direction X. FIG. Move to the downstream side of X.
In this example, the substrate support member 521 is moved 50 mm downstream in the first direction X until the rotation shaft 532a and the rotation shaft 534a coincide with the straight line L parallel to the first direction X (Fig. 21).
After the rotating shaft 532a and the rotating shaft 534a coincide with the straight line L parallel to the first direction X, and the arm portion 533 rotates in the R1 direction, the rotating shaft 532a is connected to the rotating shaft 534a. It is displaced to the downstream side of 1st direction X with respect to. Therefore, after the rotation shaft 532a and the rotation shaft 534a coincide with the straight line L parallel to the first direction X, the slider 552 (see FIG. 19) causes the substrate support member 521 to move in the first direction X. Move to the upstream side of. Thereby, the rotation shaft 532a of the holding | maintenance part 531 continues to move to a 3rd direction Y, and is spaced apart from the working position of the main compression unit 300. As shown in FIG.
20C is an explanatory diagram of a state in which the rotation angle θ 1 of the arm portion 533 is 35 °, and the rotation angle θ 2 of the holding part 531 is 35 °, and the timing t3 shown in FIG. 21 is shown. It shows the state.
In the state shown in FIG. 20C, the rotational operations of the arm portion 533 and the holding portion 531 stop, and the position of the first direction X of the support portion 536 in the substrate support member 521 is zero. Becomes That is, the support part 536 moves 50 mm from the timing t2 (refer FIG. 20B) to the timing t3 (refer FIG. 20C) to the upstream of the 1st direction X, and the timing t1 [ Return to the same position as in FIG. 20 (A)]. At this time, the display substrate 1A held by the holding unit 531 and the display substrate 1B held by the holding unit 543 are arranged along the first direction X. FIG.
In addition, in the state shown to FIG. 20C, the reference | standard bar which the supply conveyance part 510 hold | maintains the display board | substrate 1 hold | maintained by the holding | maintenance part 511 in the working position of the main crimping unit 300 ( 304). Then, the holding part 511 is moved in the third direction Y to be spaced apart from the work position.
When the rotational operations of the arm portion 533 and the holding portion 531 stop, the slider 552 (see FIG. 19) moves the substrate supporting member 521 to the downstream side in the first direction X. FIG.
FIG. 20D is an explanatory diagram of a state in which the movement of the substrate support member 521 to the downstream side in the first direction X is stopped, and shows timing t4 and t5 states shown in FIG. 21.
When the rotational operations of the arm portion 533 and the holding portion 531 stop (see FIG. 20C), the slider 552 of the linear drive unit 522 moves the substrate support member 521 downstream of the first direction X. FIG. Side by a predetermined distance (timing t4 shown in Fig. 21). In this example, the substrate support member 521 is moved 500 mm downstream in the first direction X. As shown in FIG.
At this time, the holding | maintenance part 511 of the supply conveyance part 510 conveys to the receiving position which receives a display substrate. This receiving position is spaced apart from the main compression unit 300 in the third direction Y by a predetermined distance. And the supply conveyance part 510 waits until the display board | substrate is supplied from the drawing conveyance part (not shown) provided corresponding to the press bonding unit 200 which is a previous work unit.
When the movement of the substrate support member 521 to the downstream side in the first direction X stops, the display substrate 1A held by the holding portion 531 is disposed above the center mounting table 570 (see FIG. 19). do. In addition, the display board 1B held by the holding | maintenance part 543 is arrange | positioned above the holding part in the supply conveyance part (not shown) provided corresponding to the PCB connection unit 400 which is a next work unit.
Thereafter, the lifting unit 537 (see FIG. 19) is driven, and the supporting unit 536 moves (falls) by a predetermined distance (60 mm in this example) in the second direction Z. FIG. As a result, the display substrate 1A is mounted on the center mounting table 570. And the display board | substrate 1B is mounted in the holding part in the supply conveyance part (not shown) provided corresponding to the PCB connection unit 400 (timing t5 shown in FIG. 21).
When the display substrates 1A and 1B are mounted on the holding portions at the center mounting table 570 and the supply conveying portion (not shown), the display substrates by the suction portions of the holding portion 531 and the holding portion 543 ( 1A and 1B) are released. When the predetermined time elapses, the holding units 531 and 543 open the display substrates 1A and 1B (timing t5 shown in FIG. 21). This completes the reception of the display substrates 1A and 1B.
When the receiving of the display substrates 1A and 1B is completed, the withdrawal transport unit 520 returns to the state shown in FIG. 20A. That is, after driving the elevating part 537 to raise the support part 536, the slider 552 is driven to move the substrate supporting member 521 to the upstream side in the first direction X. Next, while rotating the arm part 533 and the holding | maintenance part 531, the board | substrate support member 521 is moved to the downstream or upstream of a 1st direction, and the holding part 531 is moved to the 3rd direction Y. As shown in FIG.
The main compression unit 300 is mounted on the supplied display substrate 1 until the take-out and transport unit 520 returns from the state shown in FIG. 20D to the state shown in FIG. 20A. The main pressing operation of the member 2 is performed. In addition, the supply conveyance part 510 waits in a receiving position.
According to 2nd Embodiment mentioned above, the board | substrate support member is moved to one side or the other side of a 1st direction, rotating the arm part of a board | substrate support member about the axis parallel to a 2nd direction. Thereby, the rotation center of a 1st rotation drive part can be displaced in the 3rd direction which cross | intersects a 1st direction and a 2nd direction. For example, when the rotation shaft 532a of the holding portion 531 is displaced to the upstream side in the first direction X with respect to the rotation shaft 534a by the rotation of the rotation shaft 534a of the arm portion 533, the substrate support is supported. The member 521 is moved to the downstream side in the first direction X. On the other hand, when the rotation shaft 532a is displaced to the downstream side in the first direction X with respect to the rotation shaft 534a by the rotation of the rotation shaft 534a, the substrate supporting member 521 is moved upstream in the first direction X. Let's do it. Thereby, the rotation shaft 532a can be moved to the 3rd direction Y. As shown in FIG.
As a result, the holding portion 531 and the display substrate 1A can be moved in the third direction Y without using the linear drive shaft. As a result, the display substrate 1 can be moved in the third direction Y without providing the linear drive shaft parallel to the third direction Y. In addition, since it is not necessary to secure a space for retracting the linear drive shaft, the space for arranging the transfer unit 500 can be made small, and the whole apparatus can be miniaturized.
In addition, the arm portion 533 rotates in the R1 direction, and the holding portion 531 rotates in the R2 direction opposite to the R1 direction. Since both rotate at the same speed (the same angular velocity), the attitude toward the main compression unit 300 of the display substrate 1A held by the holding portion 531 can be made constant at all times. Therefore, the display substrate 1A conveyed in the third direction Y does not interfere with the main compression unit 300.
In addition, since the center mounting table 570 and the substrate holding arm 535 are provided, after the display substrate 1A is taken out in the third direction Y, the withdrawal conveyance unit 520 moves to the downstream side in the first direction X. You can shorten the distance. Thereby, each work unit can prevent it from carrying around waiting of 1 A of display boards, and productivity can be improved.
Moreover, in 2nd Embodiment mentioned above, in the middle of the rotation range of the arm part 533 and the holding part 531, the rotation shaft 532a and the rotation shaft 534a correspond with the straight line L parallel to 1st direction X. Moreover, as shown in FIG. It was set as the structure. However, the rotation axis of the arm part and the holding part according to the present invention may coincide with a straight line L parallel to the first direction X at any position in the rotation range of the arm part and the holding part.
For example, when the rotation angle θ 1 of the arm portion 533 of the present embodiment is 5 ° and the rotation angle θ 2 of the holding part 531 is −5 °, the rotation shaft 532a and the rotation shaft 534a are provided. May coincide with a straight line L parallel to the first direction X. That is, when the arm part 533 rotates 20 degrees in the R1 direction and the holding part 531 rotates 20 degrees in the R2 direction from the state shown in FIG. 20A, the rotation shaft 532a and the rotation shaft 534a. ) May coincide with a straight line L parallel to the first direction X.
When comprised in this way, what is necessary is just to shift the position of the rotation shaft 534a of the arm part 533 to the main crimping unit 300 side of 3rd direction Y. As shown in FIG.
In addition, in 2nd Embodiment mentioned above, the lifting part 537 made the structure which moves the arm part 533 and the board | substrate holding arm 535 to 2nd direction Z through the support part 536. As shown in FIG. However, what is necessary is just to move the holding part 531, 543 to 2nd direction Z at least in the lifting part which concerns on this invention. Therefore, arrangement | positioning of the lifting part can move the holding | maintenance part 531, 543 to 2nd direction Z, and can set it suitably.
In addition, in 2nd Embodiment mentioned above, the mounting operation of the mounting member 2 with ACF adhere | attached was made at the timing which the processing time with respect to each side at least with respect to three sides of the display board 1 overlaps. Therefore, the scale can be reduced as compared with the FPD module assembly line which processes two sides of the display substrate conventionally used.
In the above, embodiment of the assembly apparatus of the FPD module of this invention was described including the effect. However, the assembly apparatus of the FPD module of the present invention is not limited to the above-described first and second embodiments, and various applications and modifications can be made without departing from the spirit of the invention described in the claims. Do. In addition, by arbitrarily combining the above-described first and second embodiments, an FPD module assembly line which processes three sides of the display substrate 1 at a timing at which processing times for at least each side overlaps can be configured. This timing does not interfere even if there is a difference in the time between the start and end of the processing for each side of the display substrate 1 in each unit, and at least the processing time for each side should overlap. In addition, in the assembly apparatus of the FPD module according to the present invention, it is not necessary for all units to process three sides of the display substrate 1 depending on the configuration. For example, for some units, the mechanisms for individually processing may be arranged.
