Description

  The present invention relates to an FPD module assembling apparatus and assembling method for mounting an electronic component (mounting member) on an FPD module constituting a flat panel display (hereinafter referred to as FPD (Flat Panel Display)).

  Conventionally, as the FPD, for example, there are a liquid crystal display, an organic EL (Electro-Luminescence) display, a plasma display, and the like. In the FPD, a driving IC is mounted on the periphery of the display substrate, and TAB (Tape Automated Bonding) connection such as COF (Chip on Film) or FPC (Flexible Printed Circuit) is performed. A peripheral substrate such as a PCB (Printed Circuit Board) is mounted around the display substrate. As a result, the FPD module is assembled.

  The FPD module assembling apparatus is a line apparatus that assembles an FPD module by mounting mounting members such as a driving IC, a COF, and a PCB on the periphery and the periphery of the display substrate of the FPD by sequentially performing a plurality of processes.

  Here, an electronic component referred to as a “mounting member” in the following description is referred to as TCP (Tape Carrier Package) or COF (Chip On Film) due to a difference in the detailed shape or thickness of the member. Or These TCP and COF are constructed by mounting an IC chip on an FPC (Flexible Printed Circuit) in which a long polyimide film having sprocket holes is wired and cutting it out. There is no difference. Also, depending on the panel design, only an FPC without an IC chip may be mounted. In the mounting and assembling process of the FPD, since there is no substantial difference between these parts, they are referred to as mounting members in the present invention.

  As an example of the process in the assembly apparatus of the FPD module, (1) a terminal cleaning process for cleaning the mounting member attaching part of the display substrate end, and (2) an anisotropic conductive film (ACF) on the display substrate end after cleaning. : Anisotropic Conductive Film). Further, there are (3) a mounting step in which the mounting member is positioned and mounted at the position where the ACF is pasted on the display substrate, and (4) a pressing step in which the mounting member is thermocompression-bonded and fixed by the ACF. Furthermore, (5) there is a PCB process in which a PCB substrate on which an ACF has been pasted is pasted and mounted on the side opposite to the display substrate side of the mounting member. The PCB process is composed of a plurality of processes.

  ACF should just be affixed previously to either one of the members to join. For example, in another example of the ACF process, the ACF may be attached in advance to the mounting member. In addition, the FPD module assembly line requires various processing device groups depending on the number of sides of the substrate to be processed, the number of mounting members and ICs to be processed, and the like.

  By passing through a series of processes by such a processing apparatus group, the electrodes on the display substrate and the electrodes provided on the mounting member are thermocompression bonded, and the electric electrodes of the two electrodes are electrically connected via the conductive particles inside the ACF. A connection is made. When the crimping process is completed, the ACF base resin is cured, so that the display substrate and the mounting member are mechanically connected simultaneously with the electrical connection of both electrodes.

  A pressure bonding apparatus used in the process of the FPD module assembly apparatus is described in Patent Document 1. In Patent Document 1, when the display substrate supplied from the temporary pressure bonding stage is moved in the direction perpendicular to the conveyance direction of the conveyance belt, the display substrate is turned counterclockwise, and then the two sides of the display substrate are changed. Discloses a crimping apparatus for simultaneously thermocompression bonding electronic circuit components.

JP 2009-117704 A

  By the way, since the apparatus group for performing various processes for every process is arrange | positioned in an FPD module assembly line, the scale of an assembly line is easy to expand. However, with the technique disclosed in Patent Document 1, as the size of the display substrate increases, it becomes difficult to stop the display substrate at a predetermined position due to inertial force generated by rotating the display substrate. It takes time. Further, when the display substrate is rotated, a space must be provided in each processing device group by the area of a circle whose diameter is a diagonal line of the display substrate, and the line configuration tends to be redundant.

  The present invention has been made in view of such a situation, and an object thereof is to efficiently perform processing on an FPD module including a display substrate on which a mounting member is mounted.

In order to solve the above problems and achieve the object of the present invention, the present invention includes an ACF sticking device for sticking an ACF to a display substrate, a temporary pressure bonding device for temporarily pressing a mounting member to the display substrate via the ACF, The following processing is performed in an FPD module assembly line for assembling an FPD module that includes a main pressure bonding apparatus that pressure-bonds the temporarily pressed mounting member to a display substrate.
That is, the transfer line is arranged by a moving device provided in at least one of the ACF adhering device, the temporary pressure bonding device, and the main pressure bonding device, which is arranged along the conveyance line in which the display substrate is conveyed in the first direction. The display substrate is moved to a predetermined position in the direction intersecting with.
At least one of the ACF sticking device, the temporary pressure bonding device, and the main pressure bonding device overlaps at least three sides of the display substrate moved to the processing position by the moving device at least for each side. Predetermined processing is performed at the timing.

  According to the FPD module assembling apparatus of the present invention, a predetermined position in a direction intersecting the transport line using a moving device provided in at least one of the ACF adhering apparatus, the temporary crimping apparatus, and the main crimping apparatus. By moving and arranging the display substrate, the predetermined processing can be performed at the timing at which the processing time for at least each side overlaps at least three sides of the display substrate moved to the processing position. Therefore, the scale of the FPD module assembling apparatus can be reduced as compared with a conventional FPD module assembling line that performs processing for each two sides of the display substrate.

Hereinafter, an embodiment for implementing an FPD module assembling apparatus will be described with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected to the common member in each figure.
First, a first embodiment of an FPD module assembling apparatus according to the present invention will be described with reference to FIGS.

[First Embodiment: FPD Module Assembly Device]
First, the FPD module will be described with reference to FIG.
FIG. 1 is a plan view showing a schematic configuration of the FPD module according to the first embodiment of the present invention.

  As shown in FIG. 1, the FPD module 7 connects a plurality of mounting members 2 to the peripheral portion of the display substrate 1 by ACF bonding, and is connected to one long side and two short sides of the display substrate 1. A PCB 6 is connected to the member 2 by ACF. The mounting member 2 is a mounting member 2 in which an IC chip 5 is mounted on an FPC (Flexible Printed Circuit) 4 in which a printed circuit (not shown) made of copper foil is applied to a flat rectangular polyimide film. The IC chip 5 is mounted substantially at the center of the FPC 4. A printed circuit is provided on the lower surface of the FPC 4, and outer lead terminals (not shown) are provided on both sides (two long sides) in the longitudinal direction.

  Depending on the type of the mounting member 2, there is a case where the IC chip 5 is on the lower surface side (COF type) and a case where there is no IC chip (FPC type). FIG. 1 shows a form in which an IC chip 5 is inserted into the hole of the FPC 4 as an example. Further, the mounting member 2 and the PCB 6 are different from each other in terms of circuit depending on the connection site, but are not shown in the description of the mounting and mounting, and are therefore shown as the same.

FIG. 2 is a floor layout diagram showing the entire FPD module assembly line 10.
The FPD module assembly line 10 includes a receiving unit 100 as a receiving device that receives the display substrate 1, a temporary crimping unit 200 as a temporary crimping device that temporarily crimps the mounting member 2 to the display substrate 1 via the ACF, and an ACF to the display substrate 1. A main pressure bonding unit 300 as a main pressure bonding device for finally pressure bonding the mounting member 2 via the PCB, a PCB connection unit 400 as a PCB connection device for connecting a PCB to the display substrate 1, and a conveyance as a conveyance device for conveying the display substrate 1. The unit 500 is configured. Each unit has frames 103, 203, 303, 403, and 503. Conveying rails 101, 201, 301, 401, and 501 are provided on the operation surface side of each frame, and adjacent conveying rails are connected. Further, in the temporary pressure bonding unit 200, the main pressure bonding unit 300, and the PCB connection unit 400, the moving mechanisms 290, 390, and 490 that move the display substrate 1 in the Y direction intersecting the transport line are collectively referred to as “moving devices”.

  The transport rails 101, 201, 301, and 401 support the transport stages 102, 202, 302, and 402 in a movable manner. These transfer stages 102, 202, 302 and 402 transfer the display substrate 1 to the work position of the next unit. In addition, although the apparatus which receives the display board | substrate 1 is separately provided in the last conveyance unit 500, since the specification generally differs for every factory from the conveyance unit 500, it is abbreviate | omitting here.

  Reference bars 204, 304, and 404 on which work sides of the display substrate 1 are placed are provided at work positions of the temporary pressure bonding unit 200, the main pressure bonding unit 300, and the PCB connection unit 400. These reference bars 204, 304, and 404 absorb the working side of the display substrate 1 and flatten the display substrate 1. These reference bars 204, 304, and 404 stably hold the display substrate 1 in operation together with the rear end supports (not shown) of the temporary pressure bonding unit 200, the main pressure bonding unit 300, and the PCB connection unit 400.

  The temporary pressure bonding unit 200 includes a moving mechanism 290 that moves the display substrate 1 in the Y direction intersecting the transport line. In the following description, in this example, it is assumed that the Y direction is orthogonal to the transport line. And the temporary crimping | compression-bonding unit 200 is provided with the ACF sticking part 230 which sticks ACF to the mounting member 2 supplied by the mounting member supply part 220 and cut out by the punching mechanism mentioned later. The mounting member 2 to which the ACF is attached is transferred to the mounting unit 280. Then, the temporary press-bonding unit 200 temporarily press-bonds the mounting member 2 to the three sides of the long side and the short side of the display substrate 1 moved in the Y direction by the moving mechanism 290 by ACF.

  The main crimping unit 300 has three main crimping portions 320A, 320B, and 320C. Further, the main crimping unit 300 includes a moving mechanism 390 that moves the display substrate 1 in the Y direction intersecting the transport line. Then, the main crimping unit 300 performs the main crimping operation of the mounting member 2 mounted on the three sides of the long side and the short side of the display substrate 1 moved in the Y direction by the moving mechanism 390 at least for each side. Is performed at the timing of overlapping. The three main crimping portions 320A, 320B, and 320C include a main crimping head having an upper blade and a lower blade. The upper blade and the lower blade are heated by a heater, and the mounting member 2 is heated and pressed to connect to the display substrate 1.

  In order to press-bond the mounting member 2 to the display substrate 1, the display substrate 1 to which the mounting member 2 has been temporarily bonded is pressed from the lower side with the lower blade while being pressed with the upper blade. At this time, the protective sheet 340A is interposed between the mounting member 2 and the upper blade (see FIG. 8 described later). The ACF pressurized by the upper blade is heated and cured at 190 ° C. for 5 seconds, for example. The protective sheet 340 </ b> A is fed by the sheet feeding mechanism when a predetermined number of crimping operations are performed, and the used portion that contacts the upper blade is changed.

  In the main crimping unit 300, there is a moving mechanism for moving the main crimping portions 320B and 320C for final crimping the gate-side mounting member 2 temporarily crimped to both short sides of the display substrate 1 in the left-right direction (unit alignment direction). I need it. However, of the production time required for each unit, the main crimping operation with the longest production time can be performed at the timing at which the processing times for at least each side overlap. For this reason, there is an advantage that the time (around time) required from the start to the end of the process can be shortened throughout the entire process.

  The PCB connection unit 400 connects the PCB 6 to the mounting member 2 having one long side and two short sides of the display substrate 1. The PCB connection unit 400 includes a PCB supply device 430, an ACF sticking device 440, a transfer device 450, and a main crimping portion 460 on each side. Further, the PCB connection unit 400 includes a moving mechanism 490 that moves the display substrate 1 in the Y direction intersecting the transport line. When the moving mechanism 490 moves the display substrate 1 to a position where the PCB connecting unit 400 performs processing for connecting the PCB to the display substrate 1, the PCB connecting unit 400 is moved in the Y direction by the moving mechanism 490. The PCB 6 is connected to three sides of one long side and both short sides of the display substrate 1 at a timing at which the processing time for at least each side overlaps.

  The PCB supply device 430 supplies the PCB 6 supplied by a tray (not shown) one by one to the left and right ACF sticking devices 440. The ACF sticking device 440 sticks the ACF to the PCB 6 supplied from the PCB supply device 430. The transfer device 450 conveys the PCB 6 on which the ACF has been pasted to the main crimping section 460. Then, the main crimping section 460 pressurizes and heats the PCB 6 and connects it to the plurality of source-side mounting members 2.

  Thus, three processing mechanisms in which at least one of the ACF adhering unit 230, the provisional pressure bonding unit 200, the main pressure bonding unit 300, and the PCB connection unit 400 applies the same processing to the three sides of the display substrate 1, respectively. Have In the case where the two processing mechanisms out of the three processing mechanisms are in the direction intersecting the transport line and are respectively processed on two opposing sides of the display substrate 1 arranged at the processing position, Two processing mechanisms are configured to be able to approach or separate from the display substrate 1 in accordance with the size of the display substrate 1 to be moved.

As already described, the ACF attachment can be performed on the display substrate 1 side. In this case, the above-described three-side processing of the ACF pasting unit 230 can be realized by arranging the ACF pasting unit 230 on the three sides of the display substrate 1 without the mounting member supply unit 220. This modification has the effect that process changes can be avoided when there is a track record prior to ACF pasting to a glass substrate.
Further, the mounting member supply unit 220 and the ACF attaching unit 230 are arranged on the long side of the display substrate 1, and the ACF attaching unit 230 is arranged without the mounting member supplying unit 220 on the left and right short sides, thereby It is also possible to adopt a configuration in which an ACF is previously attached to the side-side mounting member 2 (for example, COF) and temporarily pressed, and an IC chip or the like is mounted in the next step on the short side. In this case, a configuration in which a minute IC chip that is difficult to recognize when the ACF is pasted on the circuit surface in advance is directly connected to the display substrate 1 is effective in increasing the mounting accuracy.

  As described above, the moving device is arranged among the ACF pasting unit 230, the provisional crimping unit 200, the main crimping unit 300, and the PCB connection unit 400 arranged along the transport line in the first direction in which the display substrate 1 is transported. The display substrate 1 is moved to a processing position in a direction intersecting the transfer line with respect to at least one of the apparatuses, and the display substrate 1 is disposed at the processing position of at least one of the apparatuses. Accordingly, at least one of the ACF pasting unit 230, the provisional pressure bonding unit 200, the main pressure bonding unit 300, and the PCB connection unit 400 is processed for at least each side of the display substrate 1 moved to the processing position by the moving device. Predetermined processing can be performed at the timing when the times overlap.

  As described above, according to the moving device in the FPD module assembly line 10, the temporary pressure bonding unit 200, the main pressure bonding unit 300, and the PCB connection unit 400 have moving mechanisms 290, 390, and 490 that move the display substrate 1 in the Y direction, respectively. Provided. For this reason, a predetermined process 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 FPD module assembly device can be shortened. The moving mechanisms 290, 390, and 490 do not necessarily have to move the display substrate 1 in a direction orthogonal to the transport line.

  In addition, although the example which moves the display board | substrate 1 to the direction which cross | intersects a conveyance direction in a horizontal direction as a moving apparatus of this example was demonstrated, it is also comprised so that the moving direction of the display board | substrate 1 may be moved to an up-down direction. Of course it is possible.

[Temporary crimping unit]
Next, the form of the temporary press-bonding unit 200 will be described with reference to FIGS. FIG. 3 is a plan view showing the provisional pressure bonding unit 200. FIG. 4 is a schematic configuration diagram of an ACF attachment unit according to the first embodiment.

  Because of the characteristics of ACF, it tends to cause elongation, so it is necessary to examine how to deal with this elongation. The ACF is formed by applying an ACF having a thickness of about 30 μm on a base film made of PET (Polyethylene Terephthalate) having a thickness of about 30 μm, and is supplied by a reel. For this reason, even if a cut such as a half cut is made in advance in the ACF so that the ACF is cut out at a necessary length, an error occurs in the length of the ACF due to the elongation of the base film. The half-cut here refers to a process of giving a cut to the ACF layer and cutting the base film layer so that the base film layer is not completely separated but maintains continuity.

  As shown in FIG. 3, the provisional pressure bonding unit 200 includes a mounting member supply unit 220, an ACF sticking unit 230, and a mounting unit 280. The mounting member supply unit 220 includes a reel 221, a reel feed mechanism 622 that rotates the reel 221, and a punching mechanism 623.

  A mounting member 2 mounted on the display substrate 1 is wound around a reel 221 as a long ribbon-like film. The reel 221 is rotated by a reel feeding mechanism 622 and feeds a ribbon-like film at a specified pitch. The punching mechanism 623 punches out the ribbon-like film sent out by the reel 221 and cuts out the mounting member 2 individually. The cut-out mounting member 2 is taken out by the take-out mechanism 624 (see FIG. 4) and supplied to the ACF sticking unit 230.

  As shown in FIG. 4, the ACF sticking unit 230 includes a carry-in cross arm 660, an ACF sticking block 670, and a carry-out cross arm 680.

  The carry-in cross arm 660 includes four arm pieces 660 a and supplies the mounting member 2 to the ACF attachment block 670. Each of the four arm pieces 660a of the carry-in cross arm 660 includes a mounting member chuck 666 that vacuum-sucks the mounting member 2. The carry-in cross arm 660 rotates by about 90 degrees, and each arm piece 660a is disposed at the take-out position, the cleaning position, the imaging position, and the placement / crimping position.

  A punching mechanism 623 and a take-out mechanism 624 are arranged at the take-out position of the mounting member 2. At this take-out position, the upside down arm 624 a of the take-out mechanism 624 takes out the mounting member 2 from the punching mechanism 623 and passes it to the mounting member chuck 666. A brush 625 is disposed at the cleaning position. In this cleaning position, the brush 625 cleans the surface to which the ACF 3a is attached in the mounting member 2 adsorbed by the mounting member chuck 666.

  A first imaging camera 626 is disposed at the imaging position. At this imaging position, the first imaging camera 626 images the mounting member 2 attracted to the mounting member chuck 666 from below, and the length of the end of the mounting member 2 (side to which the ACF 3a is pasted), the alignment mark 710A, 710B (see FIG. 5) is detected. An ACF adhering block 670 is disposed at the mounting / crimping position. At this placement / crimping position, the mounting member 2 attracted to the mounting member chuck 666 is transferred to the ACF attachment block 670. The ACF attachment block 670 will be described in detail later with reference to FIG.

  Similarly to the carry-in cross arm 660, the carry-out cross arm 680 includes four arm pieces 680a and supplies the mounting member 2 to the mounting unit 280. Each of the four arm pieces 680a of the carry-out cross arm 680 has a peeling chuck 681 that vacuum-sucks the mounting member 2. The carry-out cross arm 680 rotates by about 90 degrees, and each arm piece 680a is disposed at the peeling position, the imaging position, the carry-out position, and the standby position.

  An ACF attachment block 670 is disposed at the peeling position. At the peeling position, the mounting member 2 to which the ACF 3a (see FIG. 5) is attached is attracted to the peeling chuck 681. A second imaging camera 627 is disposed at the imaging position. At this imaging position, the second imaging camera 627 images the mounting member 2 adsorbed by the peeling chuck 681 from below. The image captured by the second imaging camera 627 is output to an image processing device (not shown), and the state of the ACF 3a attached to the mounting member 2 is inspected.

  A delivery unit 275 (see FIG. 3) is disposed at the carry-out position. At this unloading position, the mounting member 2 that has been determined to be acceptable by the inspection based on the image captured at the imaging position is delivered to the delivery unit 275. The delivery unit 275 delivers the supplied mounting member 2 to the mounting unit 280. At the standby position, the peeling chuck 681 that does not attract the mounting member 2 is on standby. In addition, the mounting member 2 in which the inspection result at the imaging position is unacceptable is discarded at the standby position and collected by a collection unit (not shown).

  Note that the carry-in cross arm 660 and the carry-out cross arm 680 described above do not necessarily need to be cross arms having four arms, and one arm for carrying in and carrying out the mounting member 2 may be used depending on the necessity of the transport tact. It can be applied to a mobile device as a book. Further, when it is necessary to transport the display substrate 1 at high speed, it is of course possible to increase the number of arms of the mechanism for loading and unloading the mounting member 2 to 6 or 8.

[ACF pasting block]
Next, the ACF sticking block 670 will be described with reference to FIG. FIG. 5 is a perspective view of the ACF attachment part according to the first embodiment.

  The ACF attachment block 670 shown in FIG. 5 attaches the ACF 3 a of the ACF tape 3 to the two sides of the mounting member 2 supplied from the carry-in cross arm 660. The ACF sticking block 670 includes a supply reel (not shown), guide rollers 691A, 691B, 691C, a base film collection unit 692, a first cutter blade 694A, and a second cutter blade 694B. Further, the ACF sticking block 670 includes an ACF guide 696, a crimping blade 697, a lower support 698, a suction receiver 699, a peeling roller 701, movable chucks 702A and 702B, and a fixed chuck 703.

  The first cutter blade 694A and the second cutter blade 694B are arranged at an appropriate interval in a direction parallel to the feed direction of the ACF tape 3 (longitudinal direction of the ACF tape). The first cutter blade 694A is moved in the vertical direction and the longitudinal direction of the ACF tape 3 by a first cutter blade drive mechanism (not shown). Further, the angle of the first cutter blade 694 </ b> A is corrected with respect to the ACF tape 3 by the first cutter blade driving mechanism.

  Similarly to the first cutter blade 694A, the second cutter blade 694B is moved in the vertical direction and the longitudinal direction of the ACF tape by a second cutter blade drive mechanism (not shown). Further, the angle of the second cutter blade 694B is corrected with respect to the ACF tape 3 by the second cutter blade driving mechanism.

  The first cutter blade 694 </ b> A and the second cutter blade 694 </ b> B perform a half cut on the ACF tape 3. A hollow arm (not shown) is provided between the first cutter blade 694A and the second cutter blade 694B. This hollow arm attaches and removes excess ACF 3a between two half cuts formed by the first cutter blade 694A and the second cutter blade 694B to an adhesive tape.

  The ACF guide 696 is a stainless steel member having a smooth surface, and the surface facing the mounting member chuck 666 is subjected to fluororesin processing. As a result, the ACF 3 a protruding from the base film 3 b does not adhere to the ACF guide 696. The ACF guide 696 movably supports the ACF tape 3 and the mounting member 2 placed on the ACF 3 a of the ACF tape 3.

  Although FIG. 5 shows that the mounting member chuck 666 is detached from the arm piece 660a of the carry-in cross arm 660, the mounting member chuck 666 is connected to the arm piece 660a and integrated. The mounting member chuck 666 is lowered together with the arm piece 660 a and presses the mounting member 2 against the ACF 3 a of the ACF tape 3 fed onto the ACF guide 696. Further, the mounting member chuck 666 and the ACF guide 696 have a built-in heater, and the mounting member 2 and the ACF tape 3 are heated at 70 to 90 ° C., for example.

  The crimping blade 697 is lowered by an elevating mechanism (not shown), and the mounting member 2 and the ACF tape 3 are sandwiched between the pressure receiving blade 698 and pressurizing at 2 MPa, for example. In addition, a heater is built in a portion facing the ACF tape 3 of the crimping blade 697 and the lower support 698, and the mounting member 2 and the ACF tape 3 are heated at, for example, 70 to 90 ° C. The heating temperature and pressure of the mounting member chuck 666, the ACF guide 696, the crimping blade 697, and the lower support 698 are appropriately set according to the characteristics of the ACF to be used.

  The moving chucks 702A and 702B sandwich the base film 3b between the two half cuts from which the excess ACF 3a has been removed. These movable chucks 702A and 702B are supported by chuck bases 705A and 705B, respectively. The chuck bases 705A and 705B move the moving chucks 702A and 702B by one pitch in the feeding direction of the ACF tape 3 or in the direction opposite to the feeding direction. The fixed chuck 703 is disposed between the guide roller 691C and the base film collection unit 692, and sandwiches the base film 3b peeled off from the ACF 3a.

Next, the operation of the ACF pasting block 670 will be described.
The direction of the ACF tape 3 is changed by the guide roller 691 </ b> A and is disposed at a fixed position on the ACF guide 696. Before the ACF tape 3 is disposed on the ACF guide 696, the ACF tape 3 is half-cut by the first cutter blade 694A and the second cutter blade 694B. At this time, the first cutter blade 694 </ b> A and the second cutter blade 694 </ b> B have the length of the end portion (side to which the ACF 3 a is attached) detected from the image captured by the first imaging camera 626 and Drive control is performed based on the inclination. The drive control of the first cutter blade 694A and the second cutter blade 694B will be described in detail later.

  The mounting member chuck 666 of the carry-in cross arm 660 conveys the mounting member 2 by vacuum suction, and places and presses the mounting member 2 on the ACF 3 a of the ACF tape 3 stretched along the ACF guide 696. At this time, the mounting member chuck 666 is driven based on the alignment marks 710A and 710B of the mounting member 2 imaged by the first imaging camera 626, and corrects the posture (X, Y, θ) of the mounting member 2 with respect to the ACF 3a. To do.

  The crimping blade 697 is lowered by an elevating mechanism (not shown), and pressurizes, for example, at 2 MPa, with the mounting member 2 and the ACF tape 3 sandwiched between the lower support 698. On the other hand, the peeling chuck 681 of the carry-out cross arm 680 sucks the mounting member 2 supported by the suction receiver 699. The moving chucks 702A and 702B each sandwich the base film 3b, and the fixed chuck 703 opens the base film 3b.

  After the pressurization, the mounting member chuck 666 releases the vacuum suction to the atmosphere and moves away from the mounting member 2. In addition, the press-fitting blade 697 that has been pressurized is raised by the elevating mechanism. The chuck bases 705A and 705B move the moving chucks 702A and 702B sandwiching the base film 3b by one pitch in the feed direction. As a result, the mounting member 2 and the ACF tape 3 are fed by one pitch in the feeding direction.

The first imaging camera 626 outputs the captured image of the end portion of the mounting member 2 to the image processing apparatus 110. The image processing apparatus 110 detects the position of the terminal portion S by using the two alignment marks 710A and 710B. Further, the length M of the end portion (side to which the ACF 3a is pasted) of the mounting member 2 is detected from the corner region M1 in the imaging region T1 and the corner region M2 in the imaging region T2. Furthermore, the inclination with respect to the terminal portion S of the front and rear sides of the mounting member 2 in the feeding direction (traveling direction) is detected. The image processing apparatus 110 detects the position and inclination of the end of the mounting member 2 with respect to the reference line from the sent image.

For the reference line, the drive output unit 113 generates a drive signal based on the cutting position determined by the arithmetic processing unit 112 and outputs the drive signal to the first cutter blade drive mechanism 265A and the second cutter blade drive mechanism 265B. . The first cutter blade driving mechanism 265A and the second cutter blade driving mechanism 265B are used as a cutting unit that cuts the ACF at the cutting position determined by the arithmetic processing unit 112.

  Based on the position of the terminal portion S, the arithmetic processing unit 112 determines a correction value for the posture (X, Y, θ) of the mounting member 2 with respect to the ACF 3a. Further, based on the length M of the end portion of the mounting member 2 and the inclination of the front and rear sides of the mounting member 2 in the feeding direction (traveling direction) with respect to the terminal portion S, the first cutter blade 694A and the second cutter blade The cutting position by 694B is determined. And the cutting position by the 2nd cutter blade 694B is memorize | stored in a memory | storage part (not shown).

  The drive output unit 113 generates a drive signal based on the cutting position by the first cutter blade 694A determined based on the current image measurement, and outputs the drive signal to the first 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 at the imaging position.

  Thereby, the first cutter blade 694A is arranged at a position corresponding to the length M of the end portion of the mounting member 2 parallel to the front side of the corresponding mounting member 2 in the feeding direction. Then, the first cutter blade drive mechanism 265A lowers the first cutter blade 694A and cuts the ACF 3a.

  Further, the drive output unit 113 extracts the cutting position by the second cutter blade 694B stored in the storage unit when the corresponding mounting member 2 is disposed at the mounting / crimping position (above the ACF guide 696). To do. And a drive signal is produced | generated based on the extracted cutting position, and it outputs to the 2nd 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.

  Accordingly, the second cutter blade 694B is disposed at a position corresponding to the length M of the end portion of the mounting member 2 parallel to the rear side of the corresponding mounting member 2 in the feed direction. Then, the second cutter blade drive mechanism 265B lowers the second cutter blade 694B and cuts the ACF 3a. As a result, the ACF 3a can be cut to a length corresponding to the corresponding mounting member 2, and the ACF 3a can be attached to the mounting member 2 with high accuracy.

Yes.

  As described above, the ACF pasting block 670 images the end of the mounting member 2 with the first imaging camera 626, performs image measurement, and determines the cutting position of the ACF 3a based on the result. As a result, the ACF 3a can be cut to a length corresponding to the individual difference of the mounting member 2, and can be attached to the corresponding mounting member 2 with high accuracy.

  The ACF pasting block 670 uses two cutter blades as a cutting part, but the number of cutter blades according to the present invention may be one. In that case, two cutting positions of the ACF 3a with respect to the mounting member 2 are cut with one cutter blade.

  In addition, in the ACF pasting block 670 according to the above-described embodiment, the example in which the half cut ACF 3a is pasted on the mounting member 2 after half-cutting the ACF tape 3 has been described, but the ACF 3a is pasted on the mounting member 2. Thereafter, the ACF tape 3 can be half-cut.

The Y-axis guide 282 is supported by the X-axis guide 283 so as to be movable. Thereby, the shuttle chuck 281 is movable in the horizontal direction. Two shuttle chucks 281 and two Y-axis guides 282 are provided. The two Y-axis guides 282 share the X-axis guide 283.

  The mounting block 285 includes a mounting base 291, a mounting member base 292, a mounting head 293, and a delivery head 294. The mounting base 291 is movably supported by the X-axis guide 286 and moves to a mounting position on the long side of the display substrate 1. The mounting member base 292, the mounting head 293, and the delivery head 294 are disposed on the mounting base 291.

  The shuttle chuck 281 approaches the mounting base 291 and passes the mounting member 2 to the mounting member base 292. The delivery head 294 delivers the mounting member 2 on the mounting member base 292 to the mounting head 293. The mounting head 293 temporarily presses (mounts) the mounting member 2 supplied from the delivery head 294 to the mounting position of the display substrate 1. At this time, prior to the movement of the mounting base 291, the pair of camera units 287 previously waiting below both ends of the mounting position each have a two-field lens, and the mounting marks on the display substrate 1 and the positioning marks on the mounting member 2 Take an image. The positioning error calculated by the image measurement is transmitted to the mounting head 293, and the mounting head 293 mounts the mounting member 2 on the display substrate 1 while adjusting (positioning) the mounting position by the received individual adjustment value. .

  Two sets of mounting blocks 285 and camera units 287 of the long side mounting unit 280A are provided corresponding to the shuttle chuck 281. The two mounting bases 291 share the X-axis guide 286.

The mounting bases 291 of the short side mounting portions 280B and 280C are movably supported by the Y-axis guide 298 and move to the mounting position on the short side of the display substrate 1.

  When the display substrate 1 is placed on the reference bar 204, the reference marks at both ends are photographed in advance by the camera unit 287 and delivered in a state where rough alignment adjustment is performed. However, in order to avoid the displacement of the mounting position due to the dimensional error of the display substrate 1, the alignment is performed individually even when mounting by the mounting head 293.

[Main crimping device]
Next, a configuration example of the main crimping unit 300 will be described.

First, a configuration example of a conventional main crimping apparatus will be described.
The crimping device used in the crimping process includes a crimping head that presses the mounting member against the display substrate. When the pressure bonding surface (upper blade) of this pressure bonding head is brought into direct contact with the mounting member, the ACF interposed between the mounting member and the display substrate protrudes and adheres to the pressure bonding surface, and the flatness of the pressure bonding surface decreases. End up. As a result, the applied pressure acting on the mounting member becomes non-uniform, and it becomes easy to cause a crimping failure.

  Therefore, a technique has been considered in which a protective sheet is interposed between the pressure bonding surface of the pressure bonding head and the mounting member so that the protruding ACF does not adhere to the pressure bonding surface of the pressure bonding head. Since the protective sheet deteriorates due to the heat of the pressure-bonding head and the pressure applied, the protective sheet is sent by the feeding mechanism at a predetermined number of times or for a predetermined time, and the used portion is changed.

[Main crimping unit]
Here, the sheet feeding mechanism of the main crimping unit 300 according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 8 is a cross-sectional view of the main crimping unit 300. FIG. 9 is an explanatory diagram showing a part of the sheet feeding mechanism 350A according to the main crimping unit 300 shown in FIG. FIG. 10 is an explanatory diagram showing an inclination changing portion of the sheet feeding mechanism according to 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 feeding mechanism 350A.

  A lower blade (not shown) is installed on the lower frame 321A. 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 at the tip of the lower blade is appropriately set according to the characteristics of the ACF used. Further, an upper frame 322A is installed on the lower frame 321A so as to straddle the lower blade. The upper frame 322A is provided with a lifting mechanism that moves the crimping head 330A in the vertical direction.

  The pressure bonding 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 upper blades 331 are fixed to the upper blade frames, respectively. The upper blade 331 is heated by a heater unit (not shown), and a tip portion having a pressure-bonding surface is kept at, for example, 150 ° C. to 350 ° C. The crimping surface of each upper blade 331 is formed in a substantially rectangular shape. The plurality of upper blades 331 attached to the plurality of upper blade frames are arranged in a straight line so that the short sides thereof face each other.

  A protective sheet 340A is interposed between the upper blade 331 and the lower blade. The protective sheet 340A is formed in a belt shape having a predetermined width, and is sent out between the upper blade 331 and the lower blade by the sheet feeding mechanism 350A.

  The sheet feeding mechanism 350A includes a sheet supply reel 351, a rotation drive unit 352, a guide roller group 353A, and a sheet collection unit 354.

  An unused protective sheet 340 </ b> A is wound around the sheet supply reel 351, and the used protective sheet 340 </ b> A is collected by the sheet collection unit 354. The rotation drive unit 352 is intermittently driven to rotate the sheet supply reel 351 intermittently. When the sheet supply reel 351 rotates, the protective sheet 340A is sent out by a predetermined feed amount at a predetermined feed speed.

  The sheet collection unit 354 collects the protective sheet 340A by a predetermined feed amount in synchronization with the driving of the rotation drive unit 352. The sheet collection unit 354 can be constituted by, for example, a collection reel and a rotation drive unit that rotates the collection reel. Further, a suction device that sucks the protective sheet 340A may be used.

  The guide roller group 353A guides the protection sheet 340A from the sheet supply reel 351 to the sheet collection unit 354 by changing the traveling direction of the protection sheet 340A. The guide roller group 353A includes guide rollers 353a and 353b arranged on the side of the lower blade. The protective sheet 340A sent out from the sheet supply reel 351 has its traveling direction changed by a guide roller (not shown) in the guide roller group 353A and is guided to the guide roller 353a.

  The rotation axis of the guide roller 353a is inclined with respect to a direction that is parallel to the horizontal direction and orthogonal to the direction in which the plurality of upper blades 331 are arranged, and moves away from the upper blade 331 toward the front of the main crimping portion 320A. The guide roller 353a guides the protective sheet 340A between the upper blade 331 of the pressure bonding head 330A and the lower blade provided on the lower frame 321A, and inclines in the horizontal direction with respect to the direction in which the plurality of upper blades 331 are arranged. . This inclination angle will be described later with reference to FIGS.

Further, the sheet feeding mechanism 350A includes an inclination changing unit 355 that changes the inclination direction of the protective sheet 340A disposed between the upper blade 331 and the lower blade. The inclination changing unit 355 is
It consists of two pressing rollers 355a and 355b and a tapered roller 355c (see FIG. 9).

The pressing rollers 355a and 355b are formed in a columnar shape and press the protective sheet 340A facing the upper blade 331 so as not to be displaced upward. Thereby, the protective sheet 340 </ b> A facing the upper blade 331 maintains a state substantially parallel to the horizontal direction. The rotation shafts of the pressing rollers 355a and 355b are substantially orthogonal to the width direction of the protective sheet 340A.
Note that the pressing rollers 355a and 355b are not limited to a cylindrical shape, and for example, a tapered roller whose diameter increases toward the front of the main pressure bonding portion 320A can be used.

  The taper roller 355c is disposed above the pressing rollers 355a and 355b. The rotation axis of the taper roller 355c is directed in a direction orthogonal to the direction in which the upper blades 331 are arranged. The diameter of the tapered roller 355c is continuously reduced toward the front side of the main pressure bonding part 320A.

  The pressing 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, the protective sheet 340A from the guide roller 353a to the pressing roller 355a and the protective sheet 340A from the pressing roller 355b to the guide roller 353b are symmetrical with respect to a plane orthogonal to the direction in which the plurality of upper blades 331 are arranged. (See FIG. 8).

  Thereby, the part which inclines in the horizontal direction with respect to the direction where the some upper blade 331 of protection sheet 340A is located in a line can be shortened. Accordingly, it is possible to suppress the forward protrusion amount of the protective sheet 340A and the guide roller 353b, and to reduce the size of the apparatus.

  Further, 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 times for at least the sides overlap, 320A, 320B, 320C are provided. Therefore, by suppressing the forward projection amounts of the protective sheet 340A and the guide roller 353b, the protective sheet 340A and the guide roller 353b can be prevented from interfering with the main crimping portions 320B and 320C.

  The guide rollers 353b and 353c change the traveling direction of the protective sheet 340A that has passed between the upper blade 331 and the lower blade, and guide it to the sheet collecting unit 354. Accordingly, the protective sheet 340A that has passed through the guide rollers 353b and 353c is collected by the sheet collecting unit 354.

  The main crimping portions 320B and 320C are disposed in front of the main crimping portion 320A, and the respective 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.

  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 by the sheet collecting section 354. When the sheet supply reel 351 is rotated by the rotation driving unit 352, the protective sheet 340B is sent out by a predetermined feed amount at a predetermined feed speed.

  The guide roller group 353B guides the protection sheet 340B from the sheet supply reel 351 to the sheet collection unit 354 by changing the traveling direction of the protection sheet 340B. The guide roller group 353B includes guide rollers 353d and 353e arranged on the side of the lower blade. The protective sheet 340B sent out from the sheet supply reel 351 has its traveling direction changed by a guide roller (not shown) in the guide roller group 353B and is guided to the guide roller 353d.

  The guide roller 353d guides the protective sheet 340B between the upper blade 331 of the pressure bonding head 330B and the lower blade (not shown) provided on the lower frame 321B, and inclines in the horizontal direction with respect to the direction in which the upper blade 331 is arranged. Let The protection sheet 340 </ b> B that has passed between the upper blade 331 and the lower blade is changed in the traveling direction by the guide roller 353 e and a guide roller (not shown), and proceeds toward the sheet collection unit 354.

The main crimping section 320C includes a lower frame 321C, an upper frame 322C, a crimping head 330C, a protective sheet 340C, and a sheet feeding mechanism 350C.
The sheet feeding mechanism 350C includes a sheet supply reel 351, a rotation drive unit 352, a guide roller group 353C, and a sheet collection unit 354.

  An unused protective sheet 340C is wound around the sheet supply reel 351 of the main crimping section 320C, and the used protective sheet 340C is collected by the sheet collecting section 354. When the sheet supply reel 351 is rotated by the rotation driving unit 352, the protective sheet 340C is sent out by a predetermined feed amount at a predetermined feed speed.

  The guide roller group 353C guides the protective sheet 340C from the sheet supply reel 351 to the sheet collection unit 354 by changing the traveling direction of the protective sheet 340C. The guide roller group 353C includes guide rollers 353f and 353g arranged on the side of the lower blade. The protective sheet 340C sent out from the sheet supply reel 351 is changed in the traveling direction by a guide roller (not shown) in the guide roller group 353C and is guided to the guide roller 353f.

  The guide roller 353f guides the protective sheet 340C between the upper blade 331 of the pressure bonding head 330C and the lower blade (not shown) provided on the lower frame 321C, and is inclined in the horizontal direction with respect to the direction in which the upper blades 331 are arranged. Let The protective sheet 340C that has passed between the upper blade 331 and the lower blade is changed in the traveling direction by the guide roller 353g and a guide roller (not shown), and proceeds toward the sheet collecting unit 354.

In the sheet feeding mechanism (350A, 350B, 350C) of the FPD module assembly line 10, the protective sheet (340A, 340B, 34) is used until the used part is detached from the upper blade 331.
0C). If the inclination angle θ of the protective sheet with respect to the direction in which the plurality of upper blades 331 are arranged is small, the amount of the protective sheet protruding in front of the pressure-bonding head can be reduced, and the apparatus can be downsized. Therefore, in the present embodiment, the inclination angle θ of the protective sheet is determined in consideration of the two points described above.

Here, the direction in which the plurality of upper blades 331 are arranged is the X direction, and the direction orthogonal to the direction in which the plurality of upper blades 331 is arranged is the Y direction. And let the length (upper blade length) of the X direction of the upper blade 331 be L, and let the space | interval (distance between upper blades) of the adjacent upper blade 331 be L1. Further, the length (upper blade width) in the Y direction of the upper blade 331 is 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 upper blade distance L1 is shorter than the upper blade length L (L> L1). As the distance L1 between the upper blades is shorter, tan θ approaches t / L (t / (L + L1) ≈t / L).
The feed amount in the X direction of the protective sheet in the first example is made equal to the length obtained by adding the upper blade length L and the upper blade distance L1, and the feed amount in the Y direction is made equal to the upper blade width t.

  Thereby, the length of the width direction of a protection sheet can be set short. Moreover, many used parts can be provided on a protection sheet, and the use efficiency of a protection sheet can be improved. And if it is said feed amount, the used part (indentation) on a protection sheet will be located in a Y direction (direction orthogonal to the direction where the some upper blade 331 is located in a line). In addition, the used portions of the protective sheets arranged in the Y direction are used by different upper blades 331, respectively.

In the second example shown in FIG. 12, the upper blade distance L1 is longer than the upper blade length L (L <L1). The distance L1 between the upper blades is twice as long as the upper blade length L. Therefore,
tan θ = t / 3L
It becomes.

  The feed amount in the X direction of the protective sheet in the second example is set to 1/3 of the length obtained by adding the distance L1 between the upper blades to the upper blade length L. That is, the upper blade length L is set equal. On the other hand, the feed amount in the Y direction is set to 1/3 of the upper blade width t.

  Thereby, the length of the width direction of a protection sheet can be set short. Moreover, many used parts can be provided on a protection sheet, and the use efficiency of a protection sheet can be improved. And if it is said feed amount, the used part on a protection sheet will be located in a line with the Y direction, and these used parts will be used by the separate upper blade 331, respectively.

In the third example shown in FIG. 13, the upper blade distance L1 is substantially equal to the upper blade length L (L = L1). Therefore,
tan θ = t / 2L
It becomes.

  The feed amount in the X direction of the protective sheet in the third example is set to ½ of the length obtained by adding the distance L1 between the upper blades to the upper blade length L. That is, the upper blade length L is set equal. On the other hand, the feed amount in the Y direction is set to ½ of the upper blade width t.

  Thereby, the length of the width direction of a protection sheet can be set short. Moreover, many used parts can be provided on a protection sheet, and the use efficiency of a protection sheet can be improved. And if it is said feed amount, the used part on a protection sheet will be located in a line with the Y direction, and these used parts will be used by the separate upper blade 331, respectively.

In the fourth example shown in FIG. 14, the interval between used parts adjacent in the Y direction is set to α so that used parts arranged in the Y direction do not contact each other. Therefore,
tan θ = (t + α) / (L + L1)
It becomes.

In this fourth example, the upper blade distance L1 is longer than the upper blade length L (L <L1). Specifically, the distance L1 between the upper blades is a length obtained by adding β to the length twice the upper blade length L. Therefore,
L + L1 = 3L + β
It becomes.
Here, 3L + β = 3L ′ and t + α is t ′. This
tan θ = t ′ / 3L ′
It becomes.

  The feed amount in the X direction of the protective sheet in the fourth example is set to 1/3 of the length obtained by adding the upper blade distance L1 to the upper blade length L. That is, 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 upper blade width t. That is, the feed amount in the Y direction is set to t ′ / 3.

  Thereby, many used parts can be provided on a protection sheet, and the use efficiency of a protection sheet can be improved. And if it is said feed amount, the used part on a protection sheet will be located in a line with the Y direction, and these used parts will be used by the separate upper blade 331, respectively.

In the fifth example shown in FIG. 15, the interval between used parts adjacent in the Y direction is set to α, as in the fourth example. Therefore,
tan θ = (t + α) / (L + L1)
It becomes.

In the fifth example, the upper blade distance L1 is longer than the upper blade length L (L <L1). Specifically, the upper blade distance L1 is a length obtained by adding β to the upper blade length L. Therefore,
L + L1 = 2L + β
It becomes.
Here, 2L + β = 2L ′ and t + α is t ′. This
tan θ = t ′ / 2L ′
It becomes.

  The feed amount in the X direction of the protective sheet in the fifth example is ½ of the length obtained by adding the upper blade distance L1 to the upper blade length L. That is, the feed amount in the X direction is set to L ′ / 2. On the other hand, the feed amount in the Y direction is ½ of the length obtained by adding α to the upper blade width t. That is, the feed amount in the Y direction is set to t ′ / 2.

  Thereby, many used parts can be provided on a protection sheet, and the use efficiency of a protection sheet can be improved to a protection sheet. And if it is said feed amount, the used part on a protection sheet will be located in a line with the Y direction, and these used parts will be used by the separate upper blade 331, respectively.

In the sixth example shown in FIG. 16, the upper blade distance L1 is shorter than the upper blade length L (L> L1). When the distance L1 between the upper blades is shorter than the upper blade length L, the inclination angle θ of the protective sheet can be determined by the following equation.
tan θ = (t + α) / n (L + L1)
However, n is a positive integer (n ≧ 1).

  Thereby, inclination-angle (theta) of a protection sheet can be made small. That is, when n is increased, 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 pressure-bonding head is limited. In addition, since the use efficiency of a protection sheet becomes low, so that n is enlarged, it is good to determine the value of n in consideration of the amount which a protection sheet protrudes ahead of a crimping head, and the use efficiency of a protection sheet.

  In the sixth example, n = 2. In this case, the feed amount in the X direction of the protective sheet is set to twice the length obtained by adding the upper blade distance L1 to the upper blade length L. That is, the feed amount in the X direction is set to 2 (L + L1). On the other hand, the feed amount in the Y direction is set to a length obtained by adding α to the upper blade width t. That is, the feed amount in the Y direction is set to t + α.

  As shown in FIG. 8, in the main crimping part 320 </ b> A of the present embodiment, the inclination angle of the protective sheet 340 </ b> A is changed by the inclination changing part 355. Therefore, in the protective sheet 340 </ b> A on the downstream side (sheet collecting unit 354 side) from the inclination changing unit 355, the upper blade 331 comes into contact with the used portion. Therefore, in the main crimping section 320A, the number of times the protective sheet 340A is used on the upstream side (sheet supply reel 351 side) of the inclination changing section 355 is halved from the allowable number.

The number of times of use described above is the number of times the upper blade 331 contacts the same portion of the protective sheet 340A. The allowable number of times is an upper limit value of the number of times that the upper blade 331 may be brought into contact with the same portion of the protective sheet 340A. The 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 a protective sheet that can perform the crimping operation up to 10 times on the same portion, the protective sheet is fed by a predetermined feed amount when the crimping operation is performed 5 times upstream from the inclination changing unit 355. Thereby, even if the upper blade 331 contacts the used part on the downstream side of the inclination changing portion 355, the number of uses does not exceed the allowable number.

[Modification of the crimping part of this crimping unit]
FIG. 17 is an explanatory view showing a modification of the crimping part of the crimping unit according to the first embodiment of the FPD module assembling apparatus of the present invention. In this modification, the configuration of the sheet feeding mechanism shown in FIG. 8 is different from that in the first embodiment. That is, by having two sheet feeding mechanisms, there are two sets of protective sheets and sheet feeding mechanisms. And since it was made not to use a protective sheet twice in the part which crimps | bonds a right and left 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 on the way.

  The main crimping unit according to the first embodiment of the FPD module assembling apparatus includes crimping portions 620A, 320B, and 320C. That is, the main crimping sections 320B and 320C are the same as those used in the main crimping unit 300 according to the first embodiment.

  As shown in FIG. 17, the crimping portion 620A includes an upper frame 622A, two protective sheets 640A and 640B, and two sheet feeding mechanisms 650A and 650B. That is, the crimping part 620A has two sets of a protective sheet and a sheet feeding mechanism. Further, the crimping portion 620A includes a lower frame and a crimping head (not shown).

  The upper frame 622A has a substantially C-shape when viewed from the front, and has a rectangular upper plate 628 and side plates 629A and 629B that are continuous with the short sides of the upper plate 628, respectively. The side plates 629A and 629B are each formed in a rectangular shape that is long in the vertical direction, and one short side is continuous with the upper plate 628.

  On one long side (front side) of the upper plate 628, notches 625a and 625b are provided to avoid interference with the protective sheets 640A and 640B. Similarly, notches 626a and 627a for avoiding interference with the protective sheets 640A and 640B are provided on one (front side) long side of the side plates 629A and 629B.

  The two protective sheets 640A and 640B are each formed in a strip shape having a predetermined width, and are interposed between the upper blade and the lower blade. And when performing a crimping | compression-bonding operation | work, it interposes between an upper blade and the mounting member 2 (refer FIG. 1). The portions interposed between the upper and lower blades of these protective sheets 640A and 640B are located on the same plane.

  The protective sheet 640A is formed in a strip shape having a predetermined width, and is fed by the sheet feeding mechanism 650A between the upper blade and the lower blade on the side plate 629A side than the intermediate portion of the upper frame 622A. On the other hand, the protective sheet 640B is formed in a belt shape having the same predetermined width as that of the protective sheet 640A, and the sheet feeding mechanism 650B is provided between the upper blade and the lower blade on the side plate 629A side than the intermediate portion of the upper frame 622A. Sent out.

  The sheet feeding mechanism 650A includes a sheet supply reel and a rotation drive unit (not shown), a guide roller group 653A, and a sheet collection unit 655A.

  The guide roller group 653A guides the protective sheet 640A from the sheet supply reel to the sheet collecting unit 655A. The guide roller group 653A includes guide rollers 653a and 653b that are arranged at predetermined intervals in a direction in which a plurality of upper blades (not shown) are arranged. The guide roller 653a is disposed on the side plate 629A side in the upper frame 622A, and the guide roller 653b is disposed in an intermediate portion in the upper frame 622A.

  The protective sheet 640A sent out from the sheet supply reel passes through the notch 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 in 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 that has passed between the upper blade and the lower blade upward, and guides it to the sheet collecting unit 655A. Accordingly, the protective sheet 640A passes through the notch 625a of the upper frame 622A and is collected by the sheet collecting unit 655A.

  The sheet feeding mechanism 650B has the same configuration as the sheet feeding mechanism 650A, and includes a sheet supply reel and a rotation driving unit (not shown), a guide roller group 653B, and a sheet collection unit 655B.

  The guide roller group 653B guides the protective sheet 640B from the sheet supply reel to the sheet collecting unit 655B. The guide roller group 653B includes guide rollers 653c and 653d that are arranged at a predetermined interval in a direction in which a plurality of upper blades (not shown) are arranged. The guide roller 653c is disposed on the side plate 629B side in the upper frame 622A, and the guide roller 653d is disposed in an intermediate portion in the upper frame 622A.

  The protective sheet 640B fed from the sheet supply reel passes through the notch 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 that has passed between the upper blade and the lower blade upward, and guides it to the sheet collection unit 655B. Accordingly, the protective sheet 640B passes through the notch 625b of the upper frame 622A and is collected by the sheet collecting unit 655B.

  Thus, in this Embodiment, it was set as the structure which provides 2 sets of a protection sheet and a sheet | seat feed mechanism with respect to the crimping | compression-bonding head of 620A of crimping | compression-bonding parts. Thereby, the protrusion amount to the front of a protection sheet can be made small rather than the case where 1 set of protection sheets and sheet feeding mechanisms are provided with respect to the pressure-bonding head of the pressure-bonding part 620A. As a result, downsizing of the device can be realized. Further, by reducing the forward protrusion amount of the protective sheet, the protective sheet can be prevented from interfering with the main crimping portions 320B and 320C (see FIG. 8).

  Furthermore, another upper blade 331 does not come into contact with a used part that deviates from the contact position of the upper blade 331, and a more stable crimping operation can be performed than the main crimping portion 320A according to the first embodiment. it can.

  In the modification of the first embodiment, two sets of the protective sheet and the sheet feeding mechanism are provided for the crimping head of the crimping portion 620A. However, the pair of the protective sheet and the sheet feeding mechanism according to the present invention is provided. Can be more than two sets.

  According to the modification including the first embodiment described above, the protective sheet is guided between the plurality of upper blades of the pressure-bonding head and the mounting member (lower blade), and the direction in which the plurality of upper blades are arranged is aligned. Tilt horizontally. When the protective sheet is fed by the sheet feeding mechanism, the used part generated by the contact of the upper blade is displaced obliquely with respect to the upper blade. Therefore, the amount of displacement of the protective sheet until the used part is removed from the crimped part by the upper blade can be reduced. As a result, the feed amount of the protective sheet can be reduced and the feed time can be shortened. Moreover, even if the displacement amount of a protective sheet is small, a used part can be removed from a crimping | compression-bonding location.

  In addition, since the feeding mechanism can be disposed on the side of the crimping head, the apparatus can be downsized and heat can be prevented from being accumulated around the crimping head. That is, in the first embodiment described above, the protective sheet can be fed in a short time while realizing downsizing of the apparatus. Further, by adjusting the feed amount of the protective sheet, many used portions can be provided on the protective sheet, and the use efficiency of the protective sheet can be increased.

  In the modification including the above-described first embodiment, the mounting time of the mounting member 2 to which the ACF is attached overlaps the processing time for each side with respect to the three sides of the display substrate 1. For this reason, the scale can be reduced as compared with the FPD module assembly line that performs processing for each two sides of the display substrate that has been conventionally used.

  In the modification including the first embodiment described above, an example in which two rows of ACFs are simultaneously pasted has been shown. However, depending on the type of COF to be mounted, ACFs may be pasted only on one side. It is not limited to attaching the ACF of the column.

[Second Embodiment: Modification of Moving Device]
Next, an FPD module assembly line 11 according to a second embodiment of the present invention will be described with reference to FIGS. Here, a modification of the moving device provided in the FPD module assembly line 10 described in the first embodiment will be described.

[FPD module assembly line]
Here, an FPD module assembly line 11 which is a second embodiment of the FPD module assembly apparatus of the present invention will be described with reference to FIG. The provisional pressure bonding unit 200, the main pressure bonding unit 300, and the PCB connection unit 400 have the same configurations as those in the FPD module assembly line 10 according to the first embodiment, and thus detailed description thereof is omitted.

  FIG. 18 is a floor layout diagram showing the entire FPD module assembly line 11. In the first embodiment described above, when the display substrate 1 is transported in the Y direction, the moving mechanism 290, 390, 490 that moves the display substrate 1 in the direction orthogonal to the X direction is used. In the embodiment, it is realized that the display substrate 1 is transported in the Y direction by using a biaxial rotationally driven arm.

  The receiving unit 100 constituting the FPD module assembly line 11, the provisional crimping unit 200, which is a mounting unit, the main crimping unit 300, and the PCB connection unit 400 are arranged in the first direction X along the transport line.

  Hereinafter, a vertical direction that intersects the first direction X is defined as a second direction Z, and a direction that intersects the first direction X and the second direction Z is defined as a third direction Y. In this example, the second direction Z is orthogonal to the first direction X, and the third direction Y is orthogonal to the first direction X and the second direction Z. Further, the receiving unit 100 side in the first direction X is the upstream side, and the PCB connection unit 400 side in the first direction X is the downstream side.

  The display substrate 1 is sequentially conveyed from the receiving unit 100 to the PCB connection unit 400, and the mounting member 2 is mounted on the peripheral portion through each processing operation process, and the PCB 6 is mounted on the mounting member 2. The FPD module assembly line 11 includes a transport unit 500 that transports the display substrate 1 to the work position of the next unit.

[Transport unit]
Next, the transport unit 500 will be described with reference to FIG.
FIG. 19 is a perspective view of the transport unit 500 related to the main crimping unit 300.

  The transport unit 500 is provided for each work unit. The transport unit 500 includes a supply transport unit 510, a take-out transport unit 520, and an intermediate stand 570.

First, the intermediate stand 570 will be described.
The intermediate stand 570 is disposed between adjacent work units. The display substrate 1 transported by the take-out transport unit 520 is placed on the intermediate table 570.

  The intermediate stand 570 is also arranged on the downstream side of the PCB connection unit 400 (see FIG. 18). An intermediate stand 570 provided on the downstream side of the PCB connection unit 400 is disposed between the PCB connection unit 400 and a transport unit (not shown).

  The intermediate stand 570 is supported by the support housing 571. The support housing 571 is formed in a hollow rectangular parallelepiped shape. A transport unit controller (not shown) is housed inside the support housing 571. The transport unit control unit controls each drive unit of the take-out transport unit 520 and the supply transport unit 510 provided for the work unit disposed on the upstream side of the accommodated support housing 571.

Next, the supply conveyance unit 510 will be described.
The supply conveyance unit 510 faces the work unit (for example, the main crimping unit 300) in the third direction Y, and is disposed between a pair of control units (control units 303A and 303B) of the work unit. The supply transport unit 510 transports the supplied display substrate 1 to the work position of the work unit and places it on a reference bar (for example, the reference bar 304).

  The supply conveyance unit 510 includes a holding unit 511, a rotation driving unit 512, an elevating unit 513, an X-axis slider 514, a Y-axis slider 515, and a Y-axis guide 516.

  The holding part 511 has an adsorption part (not shown) that vacuum-adsorbs a flat part facing downward of the display substrate 1 and holds the display substrate 1 in a detachable manner. The holding unit 511 holds the display substrate 1 delivered from the take-out and transfer unit 520 provided for the previous (upstream) work unit, and places the display substrate 1 on the reference bar of the corresponding work unit. Release the hold when placing.

  The rotation drive unit 512 rotates about a rotation axis parallel to the second direction Z. The rotation drive unit 512 includes, for example, a motor, a reduction mechanism that reduces the rotational speed of the rotation shaft of the motor, and a connection member that connects the reduction mechanism and the holding unit 511. Moreover, as a speed reduction mechanism of the rotation drive part 512, a gear reduction gear can be used, for example.

The elevating unit 513 supports the rotation driving unit 512. The elevating unit 513 moves the rotation driving unit 512 in the second direction Z. Thereby, the holding part 511 is movable in the second direction Z via the rotation driving part 512.
As this raising / lowering part 513, an air cylinder, a hydraulic cylinder, etc. are applicable, for example.

  The X-axis slider 514 supports the elevating unit 513. The Y-axis slider 515 supports the X-axis slider 514 so as to be movable in the first direction X. The X-axis slider 514 has a drive unit for moving on the Y-axis slider 515, and the Y-axis slider 515 has a drive unit for moving on the Y-axis guide 516.

  The drive unit, the rotation drive unit 512, and the elevating unit 513 of the X-axis slider 514 and the Y-axis slider 515 are controlled by a transport unit control unit (not shown) housed in the support housing 571.

  In the supply transport unit 510, when the display substrate 1 is received at the receiving position, the display substrate 1 is held by the holding unit 511. Next, the position of the display substrate 1 with respect to the holding unit 511 is detected by a camera unit (not shown). Based on the detection result, the X-axis slider 514 and the rotation drive unit 512 are driven to adjust the position of the display substrate 1 in the first direction X and the rotation direction with respect to the work position of the work unit.

  Next, the Y-axis slider 515 is driven to transport the display substrate 1 above the work position in the work unit. Then, the lift unit 513 is driven to lower the display substrate 1 and place the display substrate 1 on the reference bar of the corresponding work unit. Thereafter, the holding of the display substrate 1 by the holding unit 511 is released, and the Y-axis slider 515 is driven to return to the receiving position.

  The holding unit 511 of the supply transport unit 510 and the intermediate table 570 arranged at the receiving position are aligned in the first direction X and the positions in the second direction Z are the same.

Next, the take-out conveyance unit 520 will be described.
The take-out conveyance unit 520 takes out the display substrate 1 from the work position of the work unit (for example, the main crimping unit 300) and transfers it to the supply / conveyance unit 510 of the next unit (for example, the PCB connection unit 400).

The take-out conveyance unit 520 includes a substrate holding member 521 that holds the display substrate 1 and a linear motion drive unit 522 that moves the substrate holding member 521 in the first direction X.
The substrate holding member 521 includes a holding portion 531, a first rotation drive portion 532, an arm portion 533, a second rotation drive portion 534, a substrate holding arm 535, a support portion 536, and an elevating portion 537. And.

  The holding unit 531 has a suction unit (not shown) that vacuum-sucks a flat portion facing upward of the display substrate 1 and holds the display substrate 1 in a detachable manner. The holding unit 531 holds the display substrate 1 arranged at the work position of the work unit. Then, the holding is released when the display substrate 1 is placed on the intermediate stand 570.

  The first rotation drive unit 532 rotates the holding unit 531 around a rotation shaft 532a parallel to the second direction Z. The first rotation drive unit 532 includes, for example, a motor, a reduction mechanism that reduces the rotational speed of the rotation shaft of the motor, and a connection member that connects the reduction mechanism and the holding unit 531. In addition, as a speed reduction mechanism of the first rotation drive unit 532, for example, a gear speed reducer can be used.

  The arm portion 533 is formed in a substantially L shape. A first rotation drive unit 532 is attached to one end of the arm unit 533. Therefore, the holding portion 531 rotates about the rotation shaft 532a with respect to the arm portion 533. On the other hand, the other end of the arm portion 533 is connected to the second rotation drive portion 534.

  The second rotation drive unit 534 rotates the arm unit 533 around a rotation shaft 534a parallel to the second direction Z. Similar to the first rotation drive unit 532, the second rotation drive unit 534 includes a motor, a speed reduction mechanism, and a connection member that connects the speed reduction mechanism and the arm portion 533.

The substrate holding arm 535 includes an arm part 541, a connection part 542, and a holding part 543.
The arm portion 541 is a rectangular plate having an appropriate thickness. The connection portion 542 is formed in a columnar shape parallel to the second direction Z. One end of the connection portion 542 is fixed to one end portion of the arm portion 541. Further, the other end of the connection portion 542 is fixed to the holding portion 543. That is, the holding part 543 does not rotate with respect to the arm part 541.

  The holding unit 543 is the same as the holding unit 531, and includes a suction unit (not shown) that vacuum-sucks a flat portion facing upward of the display substrate 1. The holding unit 543 of the substrate holding arm 535 holds the display substrate 1 placed on the intermediate table 570. Then, the holding is released when the display substrate 1 is transferred to the supply conveyance unit 510 corresponding to the next work unit.

  The support unit 536 supports the second rotation drive unit 534 and the substrate holding arm 535. The support portion 536 is made of a rectangular plate having an appropriate thickness, and is arranged so that the long side is parallel to the first direction X. A second rotation drive unit 534 is fixed to the upstream end of the support unit 536. Therefore, the arm portion 533 rotates about the rotation shaft 534a with respect to the support portion 536.

  The other end portion of the arm portion 541 of the substrate holding arm 535 is fixed to the downstream end portion of the support portion 536. Therefore, the substrate holding arm 535 does not rotate with respect to the support portion 536.

A support part 536 is attached to the elevating part 537. The elevating part 537 moves the support part 536 in the second direction Z. Thereby, the holding part 543 and the holding part 531 of the substrate holding arm 535 are movable in the second direction Z via the support part 536.
As this raising / lowering part 537, an air cylinder, a hydraulic cylinder, etc. are applicable, for example.

The linear drive unit 522 includes an X-axis guide 551 and a slider 552 that moves on the X-axis guide 551.
The X-axis guide 551 is supported by guide support portions 555A and 555B disposed in the support housing 571.

  The slider 552 has a drive unit for moving on the X-axis guide 551. The drive unit of the slider 552 and the first rotation drive unit 532 and the second rotation drive unit 534 of the substrate holding member 521 are controlled by a transport unit control unit (not shown) housed in the support housing 571. Be controlled.

[Operation of take-out conveyance section]
Next, the operation of the take-out conveyance unit 520 will be described with reference to FIGS.
FIG. 20 is an explanatory diagram illustrating the operation of the take-out and transport unit 520 in the transport unit 500. FIG. 21 is a timing chart showing the operation of the take-out conveyance unit 520.

  FIG. 20A is an explanatory diagram of a state in which the holding unit 531 of the take-out conveyance unit 520 is in contact with the flat part facing upward of the display substrate 1, and shows a state at the timing t1 shown in FIG.

  In the state shown in FIG. 20A, the holding portion 531 comes into contact with the flat surface portion of the display substrate 1A at the working position of the main pressure bonding unit 300, and the holding portion 543 in the substrate holding arm 535 is on the placing table 570 (see FIG. 19). It contacts the flat part of the display substrate 1B. At this time, the position in the first direction X and the position in the second direction Z of the support portion 536 in the substrate holding member 521 are set to zero.

  At this time, the rotation angle θ1 of the holding portion 531 with respect to the arm portion 533 is −35 degrees. The rotation angle θ1 is an angle when the rotation range of the holding portion 531 is set to 70 degrees and the middle is set to 0 degrees. Accordingly, the holding portion 531 rotates from −35 degrees to 35 degrees.

  On the other hand, the rotation angle θ2 of the arm portion 533 with respect to the support portion 536 is 35 degrees. The rotation angle θ2 is an angle when the rotation range of the arm portion 533 is set to 70 degrees and the middle is set to 0 degrees. Therefore, the arm portion 533 rotates from 35 degrees to −35 degrees, and the rotation directions of the arm portion 533 and the holding portion 531 are opposite.

  When the holding units 531 and 543 come into contact with the flat portions of the display substrates 1A and 1B, the adsorption of the display substrate 1A by the adsorption unit of the holding unit 531 and the adsorption of the display substrate 1B by the adsorption unit of the holding unit 543 are started (FIG. 21). reference). When a predetermined time elapses, the holding units 531 and 543 suck and hold the display substrates 1A and 1B.

  Thereafter, the elevating part 537 (see FIG. 19) is driven, and the support part 536 moves (rises) in the second direction Z by a predetermined distance (60 mm in this example). Accordingly, the holding portions 531 and 543 holding the display substrates 1A and 1B move (rise) by a predetermined distance in the second direction Z together with the support portion 536. This state is the state at the timing t1 shown in FIG.

  In FIG. 20, the operation of the supply conveyance unit 510 is omitted, but the operations of the supply conveyance unit 510 and the take-out conveyance unit 520 are synchronized with the operations of the supply conveyance unit 510. When the holding units 531 and 543 holding the display substrates 1A and 1B start moving in the second direction Z, the supply conveyance unit 510 causes the holding unit 511 holding the display substrate 1 (not shown) to move to the main pressure bonding unit 300. Move in the third direction Y toward the working position.

  When the movement of the holding parts 531 and 543 holding the display substrates 1A and 1B in the second direction Z is completed, the second rotation driving part 534 (see FIG. 19) moves the arm part 533 in the R1 direction (see FIG. 20B). ) At a predetermined speed. Further, the first rotation driving unit 532 (see FIG. 19) rotates the holding unit 531 in the R2 direction opposite to the R1 direction at the same predetermined speed as the arm unit 533. Further, the slider 552 moves the substrate holding member 521 to the downstream side in the first direction X.

  At this time, the moving speed of the substrate holding member 521 coincides with the speed at which the rotation shaft 532a of the holding portion 531 is displaced upstream in the first direction X with respect to the rotation shaft 534a of the arm portion 533. Accordingly, the rotation shaft 532 a of the holding portion 531 moves in the third direction Y and moves away from the working position of the main crimping unit 300.

  As a result, the holding portion 531 can be moved in the first direction Y without using the linear motion shaft that guides the movement of the holding portion 531 in the first direction Y. Therefore, it is not necessary to secure a space for retracting the linear motion shaft that guides the movement of the holding portion 531 in the first direction Y until it does not interfere with the work unit. Thereby, the space for disposing the transport unit 500 can be reduced, and the entire apparatus can be reduced in size.

  Further, since the holding portion 531 rotates in the R2 direction at the same predetermined speed as the arm portion 533, the display substrate 1A moves without rotating with respect to the main pressure bonding unit 300. Thereby, since the attitude | position of the display board 1A with respect to this crimping | compression-bonding unit 300 can always be made constant, display board 1A does not interfere with this crimping | compression-bonding unit 300.

  FIG. 20B is an explanatory diagram of a state where the rotation angles θ1 and θ2 of the arm portion 533 and the holding portion 531 are 0 degrees, and shows a state at the timing t2 shown in FIG.

  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. Until the state shown in FIG. 20B is reached, the rotation shaft 532a is displaced upstream in the first direction X with respect to the rotation shaft 534a. Therefore, the slider 552 (see FIG. 19) moves the substrate holding member 521 toward the downstream side in the first direction X until the rotation shaft 532a and the rotation shaft 534a coincide with a straight line L parallel to the first direction X. Move.

  In this example, the substrate holding 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). reference).

  After the pivot shaft 532a and the pivot shaft 534a coincide with the straight line L parallel to the first direction X, when the arm portion 533 pivots in the R1 direction, the pivot shaft 532a is the first relative to the pivot shaft 534a. 1 is displaced downstream in the direction X. 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) moves the substrate holding member 521 upstream of the first direction X. Move to the side. As a result, the rotation shaft 532a of the holding portion 531 continues to move in the third direction Y and leaves the working position of the main crimping unit 300.

  FIG. 20C is an explanatory diagram of a state where the rotation angle θ1 of the arm portion 533 is 35 degrees and the rotation angle θ2 of the holding portion 531 is −35 degrees, and shows the state at the timing t3 shown in FIG. ing.

  In the state illustrated in FIG. 20C, the rotation operation of the arm portion 533 and the holding portion 531 is stopped, and the position of the support portion 536 in the substrate holding member 521 in the first direction X is zero. That is, the support portion 536 moves 50 mm upstream in the first direction X from the timing t2 (see FIG. 20B) to the timing t3 (see FIG. 20C), and is at the same position as the timing t1 (see FIG. 20A). Return to. At this time, the display substrate 1 </ b> A held by the holding unit 531 and the display substrate 1 </ b> B held by the holding unit 543 are aligned along the first direction X.

  In the state shown in FIG. 20C, the supply conveyance unit 510 places the display substrate 1 held by the holding unit 511 on the reference bar 304 at the work position of the main crimping unit 300. Then, the holding unit 511 is moved in the third direction Y to move away from the work position.

  When the rotation of the arm portion 533 and the holding portion 531 is stopped, the slider 552 (see FIG. 19) moves the substrate holding member 521 to the downstream side in the first direction X.

  FIG. 20D is an explanatory diagram of a state in which the movement of the substrate holding member 521 to the downstream side in the first direction X is stopped, and shows the states at timings t4 and t5 shown in FIG.

  When the rotation operation of the arm portion 533 and the holding portion 531 is stopped (see FIG. 20C), the slider 552 of the linear motion driving portion 522 moves the substrate holding member 521 by a predetermined distance downstream in the first direction X. (Timing t4 shown in FIG. 21). In this example, the substrate holding member 521 is moved 500 mm downstream in the first direction X.

  At this time, the holding unit 511 of the supply transport unit 510 transports the display substrate to a receiving position. This receiving position is separated from the main crimping unit 300 in the third direction Y by a predetermined distance. Then, the supply / conveyance unit 510 waits until a display substrate is supplied from an extraction / conveyance unit (not shown) provided corresponding to the temporary press-bonding unit 200 that is the previous work unit.

  When the movement of the substrate holding member 521 to the downstream side in the first direction X is stopped, the display substrate 1A held by the holding unit 531 is disposed above the intermediate table 570 (see FIG. 19). Further, the display substrate 1B held by the holding unit 543 is disposed above the holding unit in a supply conveyance unit (not shown) provided corresponding to the PCB connection unit 400 which is the next work unit.

  Thereafter, the elevating part 537 (see FIG. 19) is driven, and the support part 536 moves (lowers) in the second direction Z by a predetermined distance (60 mm in this example). As a result, the display substrate 1 </ b> A is placed on the intermediate stand 570. Then, the display substrate 1B is placed on a holding unit in a supply conveyance unit (not shown) provided corresponding to the PCB connection unit 400 (timing t5 shown in FIG. 21).

  When the display substrates 1A and 1B are placed on the holding units in the intermediate table 570 and the supply transfer unit (not shown), the adsorption of the display substrates 1A and 1B by the adsorption units of the holding unit 531 and the holding unit 543 is released. . And when predetermined time passes, holding | maintenance part 531 and 543 will open display board 1A, 1B (timing t5 shown in FIG. 21). Thereby, the delivery of the display substrates 1A and 1B is completed.

  When the transfer of the display substrates 1A and 1B is completed, the take-out conveyance unit 520 returns to the state shown in FIG. 20A. That is, after the elevating part 537 is driven to raise the support part 536, the slider 552 is driven to move the substrate holding member 521 upstream in the first direction X. Next, while rotating the arm portion 533 and the holding portion 531, the substrate holding member 521 is moved to the downstream side or the upstream side in the first direction, and the holding portion 531 is moved in the third direction Y.

  Until the take-out conveyance unit 520 returns from the state shown in FIG. 20D to the state shown in FIG. 20A, the main crimping unit 300 performs the main crimping operation of the mounting member 2 on the supplied display substrate 1. Further, the supply conveyance unit 510 stands by at the receiving position.

  According to the second embodiment described above, the substrate holding member is moved to one or the other in the first direction while the arm portion of the substrate holding member is rotated about an axis parallel to the second direction. . Thereby, the rotation center of the 1st rotation drive part can be displaced to the 3rd direction which intersects the 1st direction and the 2nd direction. For example, when the rotation shaft 532a of the holding portion 531 is displaced upstream 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 holding member 521 is moved to the first position. To the downstream side in the direction X. On the other hand, when the rotation shaft 532a is displaced downstream in the first direction X with respect to the rotation shaft 534a by the rotation of the rotation shaft 534a, the substrate holding member 521 is moved upstream in the first direction X. Let Thereby, the rotating shaft 532a can be moved in the third direction Y.

  As a result, the holding unit 531 and the display substrate 1A can be moved in the third direction Y without using the linear motion shaft. As a result, the display substrate 1 can be moved in the third direction Y without providing a linear motion axis parallel to the third direction Y. Further, since it is not necessary to secure a space for retracting the linear movement shaft, the space for arranging the transport unit 500 can be reduced, and the entire apparatus can be reduced in size.

  Further, 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 of them rotate at the same speed (the angular velocities are the same), the posture of the display substrate 1A held by the holding portion 531 with respect to the main pressure bonding unit 300 can always be made constant. Therefore, the display substrate 1 </ b> A transported in the third direction Y does not interfere with the main crimping unit 300.

  In addition, since the intermediate table 570 and the substrate holding arm 535 are provided, the distance that the take-out conveyance unit 520 moves downstream in the first direction X after the display substrate 1A is pulled out in the third direction Y is shortened. Can do. Thereby, each work unit can be prevented from waiting for conveyance of the display substrate 1A, and productivity can be improved.

  In the second embodiment described above, the rotation shaft 532a and the rotation shaft 534a coincide with the straight line L parallel to the first direction X in the middle of the rotation range of the arm portion 533 and the holding portion 531. The configuration. However, the rotation axes of the arm part and the holding part according to the present invention may coincide with the 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 θ1 of the arm portion 533 of this embodiment is 5 degrees and the rotation angle θ2 of the holding portion 531 is −5 degrees, the rotation shaft 532a and the rotation shaft 534a are moved in the first direction. It can also coincide with a straight line L parallel to X. That is, when the arm portion 533 rotates 20 degrees in the R1 direction from the state shown in FIG. 20A and the holding portion 531 rotates 20 degrees in the R2 direction, the rotation shaft 532a and the rotation shaft 534a are moved in the first direction X. It is also possible to match with a straight line L parallel to.
In the case of such a configuration, the position of the rotation shaft 534a of the arm portion 533 may be shifted to the main pressure bonding unit 300 side in the third direction Y.

  In the second embodiment described above, the elevating unit 537 moves the arm unit 533 and the substrate holding arm 535 in the second direction Z via the support unit 536. However, the elevating unit according to the present invention only needs to move at least the holding units 531 and 543 in the second direction Z. Therefore, the arrangement of the elevating units can be set as appropriate as long as the holding units 531 and 543 can be moved in the second direction Z.

  Further, in the second embodiment described above, the mounting operation of the mounting member 2 to which the ACF is attached is performed at a timing at which the processing time for at least each side overlaps the three sides of the display substrate 1. For this reason, the scale can be reduced as compared with the FPD module assembly line that performs processing for each two sides of the display substrate that has been conventionally used.

  The embodiment of the FPD module assembling apparatus according to the present invention has been described above including the effects thereof. However, the FPD module assembling apparatus according to the present invention is not limited to the first and second embodiments described above, and various applications can be made without departing from the gist of the invention described in the claims. Variations are possible. Further, by arbitrarily combining the first and second embodiments described above, it is possible to configure an FPD module assembly line that processes at least three sides of the display substrate 1 at a timing at which the processing time for each side overlaps. Is possible. This timing may be different in processing start time and processing end time for each side of the display substrate 1 in each unit, and at least the processing time for each side may be overlapped. Further, the FPD module assembling apparatus according to the present invention may not require that all units perform processing on the three sides of the display substrate 1 depending on the configuration. For example, some units may be arranged with mechanisms for performing individual processing.
