Description

  The present invention relates to an FPD module assembling apparatus for mounting electronic components (mounting components) on a display panel of a flat panel display (FPD).

  Examples of the FPD include a liquid crystal display, an organic EL (Electro-Luminescence) display, and a plasma display. 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 assembly device is a line device that assembles an FPD module by mounting mounting members such as a drive IC, COF, and PCB on the periphery and periphery of the display substrate of the FPD by sequentially performing a plurality of processing work steps. is there.

  Here, an electronic component referred to as a mounting member in the present invention is referred to as a TCP (Tape Carrier Package) or a COF (Chip On Film) due to a difference in the detailed shape or thickness of the member. 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 processing steps in the FPD module assembly apparatus, (1) a terminal cleaning step for cleaning the mounting member affixing portion of the display substrate end, and (2) an anisotropic conductive film ( There is an ACF process for attaching an ACF (Anisotropic Conductive Film). Further, there are (3) a mounting process in which the mounting member is positioned and mounted at the position where the ACF is attached to the display substrate, and (4) a pressing process 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.

  The ACF may be attached in advance to either one of the members to be joined. That is, in another example of the ACF process, the ACF is attached in advance to the mounting member.

  Through such a series of steps, the electrodes on the display substrate and the electrodes provided on the mounting member are thermocompression bonded, and the electrodes are electrically connected through the conductive particles inside the ACF. . 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.

  For example, Patent Document 1 discloses an FPD module assembling apparatus. In the FPD module assembling apparatus described in Patent Document 1, units for performing each process are arranged in a first direction (X direction), and a transport mechanism that holds a display substrate and transports between adjacent units is provided. I have.

  The transport mechanism includes a panel holder that holds the display substrate, and an X-axis driving unit, a Y-axis driving unit, a Z-axis driving unit, and a rotating unit that move the panel holder. The X-axis drive means moves the panel holder in the X direction. The Y-axis driving means moves the panel holder in the Y direction orthogonal to the X direction, and the Z-axis driving means moves the panel holder in the Z direction orthogonal to the X direction and the Y direction. The rotating means rotates the panel holder around an axis parallel to the Z direction.

  The transport mechanism holds the display substrate placed on the work table of each unit by the panel holder, and then moves the display substrate in the Y direction by the Y-axis driving unit. Next, the panel holder is moved in the X direction by the X-axis driving means, and the display substrate is transported to the display substrate transfer position. At the delivery position, the display substrate is delivered by being raised in the Z direction from a position below the delivery-side panel holder.

JP 2007-99466 A

  However, the conveyance mechanism in the FPD module assembly apparatus described in Patent Document 1 generally uses a linear motion shaft. Therefore, in order to move the panel holder along the linear movement axis of the X driving means, the linear movement axis of the Y axis driving means and the display substrate have to be moved (retracted) to a position where they do not interfere with each unit. As a result, it is necessary to secure a space for retracting the linear movement shaft of the Y-axis driving means, and there is a problem that the apparatus becomes large.

  For example, when the linear motion shaft of the Y-axis drive means is retracted in the Y direction, the apparatus becomes large in the Y direction. In addition, when the linear motion shaft of the Y-axis drive unit is retracted in the Z direction, the apparatus becomes large in the Z direction.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an FPD module assembling apparatus capable of reducing the size of the apparatus by reducing the space for disposing the transport mechanism in consideration of the actual situation in the prior art.

In order to solve the above problems and achieve the object of the present invention, an FPD module assembling apparatus according to the present invention is an FPD module assembling apparatus in which a plurality of work units each performing work on a display substrate are arranged in a first direction. And it is provided with the board | substrate holding member and the linear drive part.
The substrate holding member includes a holding unit that detachably holds the display substrate, a first rotation driving unit, an arm unit, and a second rotation driving unit. The first rotation driving unit rotates the holding unit about an axis that is orthogonal to the first direction and parallel to a second direction that is orthogonal to the plane of the display substrate. The first rotation driving unit is attached to the arm unit. The second rotation driving unit rotates the arm unit around an axis parallel to the second direction.
The linear motion drive unit moves the substrate holding member in the first direction.
The first rotation driving unit of the substrate holding member rotates the holding unit holding the display substrate in a direction opposite to the rotation direction of the arm unit. Then, the linear motion drive unit moves the substrate holding member to one or the other of the first directions according to the rotation amount of the arm unit, so that the display substrate held by the holding unit is moved in the first direction and the second direction. Transport in a third direction orthogonal to the direction.

  In the FPD module assembly apparatus configured as described above, the substrate holding member is moved in one or the other direction in the first direction while the arm portion of the substrate holding member is rotated around an axis parallel to the second direction. Thereby, the rotation center of the first rotation drive unit can be displaced in the third direction orthogonal to the first direction and the second direction. In addition, the holding portion that holds the display substrate rotates in a direction opposite to the rotation direction of the arm portion. For this reason, the posture of the display substrate with respect to the work unit can always be made constant.

  As a result, the display substrate can be moved in the third direction without providing a linear motion axis parallel to the third direction. Therefore, the space for arranging the transport mechanism can be reduced, and the entire apparatus can be reduced in size.

  According to the FPD module assembling apparatus having the above-described configuration, the space for arranging the transport mechanism can be reduced and the apparatus can be miniaturized.

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 means 520 is placed on the intermediate mounting table 570.

  The intermediate stand 570 is also arranged on the downstream side of the PCB connection unit 400 (see FIG. 2). 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 carry-out 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 the drive units 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 stored support housing 571.

Next, the supply conveyance unit 510 will be described.
The supply / conveyance means 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 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.

  When the supply substrate 510 receives the display substrate 1 at the receiving position, the holding substrate 511 holds the display substrate 1. 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 conveyance 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 conveying means 520 will be described.
The take-out and transport unit 520 takes out the display substrate 1 from the work position of the work unit (for example, the main crimping unit 300) and passes it to the supply and transport unit 510 of the next unit (for example, the PCB connection unit 400).

The take-out conveyance means 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 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.

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

<Operation of take-out conveying means>
Next, the operation of the take-out conveying means 520 will be described with reference to FIGS.
FIG. 4 is an explanatory diagram showing the operation of the take-out and transport means 520 in the transport unit 500. FIG. 5 is a timing chart showing the operation of the take-out conveying means 520.

  4A is an explanatory diagram of a state in which the holding unit 531 of the take-out conveying 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. 4A, 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. 3). 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 θ ₁ of the holding portion 531 with respect to the arm portion 533 is −35 degrees. This θ ₁ 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 θ ₂ of the arm portion 533 with respect to the support portion 536 is 35 degrees. This θ ₂ 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 portions 531 and 543 come into contact with the flat portions of the display substrates 1A and 1B, the suction of the display substrate 1A by the suction portion of the holding portion 531 and the suction of the display substrate 1B by the suction portion of the holding portion 543 are started (FIG. 5). 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. 3) 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. 4, the operation of the supply transport unit 510 is omitted, but the operations of the supply transport unit 510 and the take-out transport unit 520 are synchronized with the operation of the supply transport unit 510. When the holding portions 531 and 543 holding the display substrates 1A and 1B start moving in the second direction Z, the supply / conveying means 510 causes the holding portion 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 portions 531 and 543 holding the display substrates 1A and 1B in the second direction Z is completed, the second rotation driving portion 534 (see FIG. 3) moves the arm portion 533 in the R1 direction (see FIG. 4B). ) At a predetermined speed. Further, the first rotation drive unit 532 (see FIG. 3) rotates the holding unit 531 in the R2 direction, which is the opposite direction 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, the display board | substrate 1A does not interfere with this crimping | compression-bonding unit 300.

FIG. 4B is an explanatory diagram of a state where the rotation angles θ ₁ and θ ₂ 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. 4B, 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. 4B 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. 3) moves the substrate holding member 521 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. 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 a straight line L parallel to the first direction X (FIG. 5). 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. 3) 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. 4C 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 a state at the timing t3 shown in FIG. ing.

  In the state shown in FIG. 4C, 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. 4B) to the timing t3 (see FIG. 4C), and is at the same position as the timing t1 (see FIG. 4A). 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. 4C, 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 operation of the arm portion 533 and the holding portion 531 is stopped, the slider 552 (see FIG. 3) moves the substrate holding member 521 to the downstream side in the first direction X.

  FIG. 4D 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. 4C), 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. 5). 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 moves to a receiving position for receiving the display substrate. 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 stands by 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. 3). Further, the display substrate 1B held by the holding unit 543 is disposed above the holding unit in the supply / conveyance means (not shown) provided corresponding to the PCB connection unit 400 which is the next work unit.

  Thereafter, the elevating part 537 (see FIG. 3) 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 t4 shown in FIG. 5).

  When the display substrates 1A and 1B are placed on the holding units in the intermediate table 570 and the supply / conveyance means (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. . When a predetermined time elapses, the holding units 531 and 543 open the display substrates 1A and 1B (timing t5 shown in FIG. 5). Thereby, the delivery of the display substrates 1A and 1B is completed.

  When the delivery of the display substrates 1A and 1B is completed, the take-out conveying means 520 returns to the state shown in FIG. 4A. 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.

  The main pressure bonding unit 300 performs the main pressure bonding operation of the mounting member 2 on the supplied display substrate 1 until the take-out conveyance unit 520 returns from the state illustrated in FIG. 4D to the state illustrated in FIG. 4A. Further, the supply conveyance unit 510 stands by at the receiving position.

  According to the above-described embodiment, 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 downstream in the first 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. Therefore, since it is not necessary to secure a space for retracting the linear motion 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 1A moving in the third direction Y does not interfere with the main pressure bonding unit 300.

  In addition, since the intermediate table 570 and the substrate holding arm 535 are provided, the distance that the take-out conveying 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 1, and productivity can be improved.

  In the above-described embodiment, 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. 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 is rotated 20 degrees in the R1 direction from the state shown in FIG. 4A and the holding portion 531 is rotated 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 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.

  In the first and second embodiments described above, the mounting operation of the mounting member 2 to which the ACF is attached is performed simultaneously on the three sides of the display substrate 1. However, some FPD modules, for example, connect the mounting member 2 (electronic component) only to one side of the display substrate 1. Accordingly, the provisional pressure bonding unit according to the present invention may be configured to perform the mounting operation of the mounting member 2 on at least one side of the display substrate 1. Similarly, the main pressure bonding unit according to the present invention may be configured to perform the pressure bonding operation of the mounting member 2 mounted on at least one side of the display substrate 1.

  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 of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the invention described in the claims.
