Description

  The present invention relates to an FPD module assembling apparatus, and more particularly to an FPD module assembling apparatus capable of efficiently mounting electronic components on display panel substrates of various sizes when electronic components are thermocompression bonded to the display panel substrate. .

  The FPD module assembly device performs peripheral processing on display panel substrates by sequentially performing multiple processing steps on FPD (Flat Panel Display) display panel substrates such as liquid crystal displays, plasma displays, and organic EL (Electro-Luminescence). Drive IC is mounted on the part, TAB (Tape Automated Bonding) connection such as COF (Chip On Film) and FPC (Flexible Printed Circuit), or peripheral substrate such as PCB (Printed Circuit Board) around the display substrate It is a device that implements.

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

  As processing steps of the FPD module assembling apparatus, usually, (1) a terminal cleaning step for cleaning the TAB attaching portion at the end of the display panel substrate, and (2) an anisotropic conductive film (ACF) at the end of the display panel substrate after cleaning. : Anisotropic Conductive Film) panel side ACF pasting process, (3) Temporary crimping process for positioning and mounting TAB or IC at the position where ACF is pasted on the display panel substrate, (4) Mounted TAB or IC (5) PCB side ACF pasting process for pasting ACF on PCB, (6) Pasting PCB with ACF on the opposite side of TAB panel substrate side There is a PCB mounting and crimping process to be mounted.

  The ACF only needs to be affixed to any one of the members to be joined in advance, and there is an example in which the ACF is affixed to the mounting member in the (2) panel-side ACF affixing step. In addition, the FPD module assembling apparatus requires a processing apparatus that rotates the substrate in accordance with the number of sides of the substrate to be processed, the number of mounting members, the number of processing apparatuses, and the like.

  Through such a series of steps, the electrodes on the display panel 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. It is. When the crimping process is completed, the ACF base resin is cured, so that the display panel substrate and the mounting member are mechanically connected simultaneously with the electrical connection of both electrodes.

  (4) The main pressure bonding apparatus used in the main pressure bonding process includes a pressure bonding head that presses the mounting member against the display panel substrate. When the crimping surface (upper blade) of this crimping head is brought into direct contact with the mounting member, the ACF interposed between the mounting member and the display panel substrate protrudes and adheres to the crimping surface, and the flatness of the crimping surface decreases. End up. As a result, the applied pressure acting on the mounting member becomes non-uniform, and a crimping failure is likely to occur.

  Therefore, a technique of interposing a protective sheet between the crimping head and the mounting member at the time of ACF crimping to prevent the protruding ACF from adhering to the crimping surface of the crimping head and maintaining the flatness of the crimping surface at the time of crimping. It has been implemented.

  Since the protective sheet deteriorates due to the heat of the head and the pressure applied, it is sent by the feeding mechanism at a predetermined number of times or for a predetermined time, and the used portion is changed. Usually, the protective sheet is wound around a tape reel or a cassette reel. By repeating the sheet feeding process, the sheet disappears, and a new reel or cassette needs to be replaced.

  A crimping apparatus using such a protective sheet is described in Patent Document 1, for example. In the crimping apparatus described in Patent Document 1, a longitudinal feeding method is employed in which the protective sheet is fed in a direction orthogonal to the direction in which the upper blades of the crimping head are arranged.

  Moreover, as another example of the crimping | compression-bonding apparatus using a protection sheet, there exist some which are described in patent document 2, for example. In the pressure bonding apparatus described in Patent Document 2, a lateral feed method is employed in which a protective sheet is fed in the direction in which the upper blades of the pressure bonding head are arranged.

JP-A-8-184847 JP 2010-182825 A

  As described above, since the protective sheet is wound and supplied on a tape reel or a cassette reel, once the sheet is exhausted, the operation of the apparatus is stopped once, and the last part of the previous tape-shaped protective sheet and the next protection are stopped. After connecting the leading edge of the sheet with connecting tape, the operation of the device was resumed.

  As described above, there is a problem in that the production efficiency is lowered due to the work due to the supply of the protective sheet being cut off.

  In regard to the above-described conventional technology, no consideration is given to the point of preventing the production efficiency from being lowered for such replacement of the protective sheet.

  The crimping apparatus described in Patent Document 2 is a lateral feed system that feeds a protective sheet in the direction in which the upper blades of the crimping head are arranged. For this reason, the feeding amount increases, the consumption of the protective sheet increases, the frequency of replacement of the tape reel or cassette reel increases, and the vertical movement of the pressure-bonding head must be stopped each time, resulting in poor production efficiency.

  On the other hand, the crimping apparatus described in Patent Document 1 is a longitudinal feeding method in which a protective sheet is fed in a direction orthogonal to the direction in which the upper blades of the crimping head are arranged. Therefore, the feed amount of the protective sheet can be made relatively small. However, when the protective sheet wound around the protective sheet supply reel runs out and a new supply reel needs to be replaced, the upper and lower movements of the crimping head must still be stopped because the upper crimping blade is straddled. Becomes worse.

  The present invention has been made to solve the above-described problems, and the object thereof is not to stop the operation of the crimping head of the crimping apparatus when replacing the supply reel of the protective sheet in the crimping process of the FPD module assembling apparatus. Accordingly, an object of the present invention is to provide an FPD module assembling apparatus capable of improving the module production efficiency.

  The FPD module assembling apparatus of the present invention is an FPD module assembling apparatus in which a protective sheet is interposed between the crimping blade and the mounting member when the mounting member is crimped to the display panel substrate.

  The FPD module assembling apparatus includes a control unit, a sheet supply unit that supplies a protective sheet, a crimping unit unit that crimps a mounting member to a display panel substrate with a crimping blade, and a sheet collection unit.

The sheet supply unit includes a supply reel on which the protective sheet is wound, a supply roller that rotates to pull out the protective sheet from the supply reel, a feed roller that sends the protective sheet to the pressure-bonding unit, a supply roller, and the feed A buffer mechanism for storing the protection sheet is provided in a conveyance path of the protection sheet between the rollers. The buffer mechanism is attached to a fixed roller and a movable member movable by conveyance of the protection sheet. And a protective sheet is routed between the fixed roller and the moving roller.

  The buffer mechanism unit further includes a first position sensor that detects the first position of the moving member, and the control unit rotates the supply motor connected to the supply roller to cause the protective sheet to move to the buffer mechanism unit. And the feed motor connected to the feed roller is rotated to feed the protective sheet from the buffer mechanism to the crimping unit, and the feed motor and the feed motor are controlled so that the first position sensor detects the moving member. It is what you do.

  Further, the buffer mechanism unit further includes a second position sensor that detects the limit of the rising of the moving member, and when the second position sensor detects the moving member, the control unit stops the crimping operation in the crimping unit. It is what you do.

  According to the present invention, the operation of the crimping head of the crimping device does not have to be stopped when replacing the supply reel of the protective sheet in the crimping process of the FPD module assembling device, thereby improving the production efficiency of the FPD module. It is possible to provide an FPD module assembling apparatus that can perform such an operation.

It is a control block diagram of a crimping device. In order to explain the state of sheet feeding in the S direction, FIG. It is a figure for demonstrating the use condition in the protection sheet. It is a figure which shows the other form of the buffer mechanism part in a sheet supply part. It is the figure which looked at the mode at the time of an assembly from the diagonal direction, in order to demonstrate the process of assembling an FPD module.

  Hereinafter, an embodiment according to the present invention will be described with reference to FIGS. 1 to 7.

First, the process of assembling the FPD module by the FPD module assembling apparatus according to the embodiment of the present invention will be described with reference to FIG.
FIG. 7 is a view of the assembling state seen from an oblique direction in order to explain the process of assembling the FPD module.
(1) Terminal cleaning step: This is a step of cleaning the peripheral terminal region of the display panel substrate 7. The cleaning tape 28 soaked with a solvent or the like wipes and removes the foreign matter from the terminal portion 29. As another foreign matter removing method, a method using UV or plasma may be used.
(2) Panel side ACF sticking step: A step of sticking the anisotropic conductive film (ACF) 30 to the display panel substrate 7. The ACF tape 30 is softened at a temperature of several tens of degrees Celsius or less to around 100 degrees Celsius and temporarily attached 31 to the component mounting position of the display substrate panel 7.
(3) Temporary pressure bonding process: This is a process of mounting 33 and 35 mounting members (such as COF 32 and COG (panel substrate peripheral mounting IC) 34) around the display substrate panel 7. The reference mark provided on the substrate panel 7 and the reference mark provided on the mounting member are detected and positioned, and heating and pressurization are performed so as not to shift the position, and mounting 33 and 35 is performed at predetermined positions.
(4) Main press-bonding step: In the temporary press-bonding step, the parts mounted around the substrate panel substrate are subjected to high-temperature heating and pressurization at a high temperature of about several hundred degrees Celsius by the press-bonding head 9, thereby ensuring conduction and curing the ACF.
(5) PCB-side ACF sticking step: a step of sticking the anisotropic conductive film (ACF) 30 to the peripheral substrate (PCB) 10.

(6) PCB mounting / crimping step: A step of crimping the peripheral circuit board 10 around the substrate panel 7. The peripheral circuit board 10 is positioned on the opposite side of the mounting member attached to the board panel 7 and heated 5 at a high temperature of about several hundred degrees Celsius, so that conduction is secured and the ACF is cured and bonded.

  In addition, processes such as inspection in each process are performed as necessary.

Next, the structure of the crimping apparatus that performs the crimping process will be described with reference to FIGS. 1 and 3.
FIG. 1 is a front view showing the structure of the crimping apparatus.
FIG. 2 is a front view showing the structure of the sheet supply unit.
FIG. 3 is a control block diagram of the crimping apparatus.

  As shown in the figure, the crimping apparatus includes a sheet supply unit 1 that sends a protective sheet to the crimping head unit 2, a crimping head unit 2 that heats and presses the display panel substrate, and a sheet collecting unit 3 that collects the protective sheet.

  First, the structure of the crimping head part 2 will be described.

  The pressure-bonding head portion 2 is composed of two types of frames, that is, an up-and-down mechanism base frame 203 and a pressure-bonding head base frame 205.

  On the vertical mechanism base frame 203, a motor connection block 206 for connecting the servo motor 201 and a vertical guide 202 are installed. An upper / lower slider 207 is installed on the block of the upper / lower guide 202, and the servo motor 201 and the upper / lower slider 207 are directly connected to each other through a ball screw 208 and a coupling 209 to perform an up / down operation.

  Two rows of horizontal slide guides 210 and a panel cradle 211 are installed on the pressure-bonding head base frame 205. A plurality of crimping heads 204 are installed on the block of the horizontal slide guide 210. The crimping head 204 can be moved in the X direction and is fixed in the Y direction. The crimping head 204 has a cylinder 212 for controlling pressure and a heater 213 for heating the crimping blade 214. Further, the upper part of the crimping head 204 is connected via an up / down slider 207 and a lateral slide guide 215.

  Then, the display panel substrate is installed on the panel cradle by a transport unit (not shown), and the operation of the servo motor 201 lowers the pressure-bonding head to heat and press the mounting member. At this time, the protective sheet S is sandwiched between the substrate panel and the crimping blade 214 to maintain the flatness of the crimping blade 214 and prevent the protruding ACF from adhering to the crimping surface of the crimping head. In addition, the raw material of this protective sheet S can use silicon rubber, a polyimide, etc.

  Next, the structure of the sheet supply unit 1 will be described.

  As shown in FIG. 2, the sheet supply unit 1 includes a supply reel 102, an end detection sensor 103, a supply roller 104, a feed roller 107, a sheet breakage detection sensor 114, a buffer mechanism unit 115, and guide rollers 120a to 120h.

  The supply reel 102 is a reel that supplies the protective sheet S. When the protective sheet S is completely removed, the supply reel 102 needs to be replaced. The supply reel 102 supplies the protective sheet S by rotating a supply motor (not shown).

  The end detection sensor 103 is a sensor for detecting the end of the protective sheet S supplied from the supply reel 102.

  The supply roller 104 is connected to a supply motor (not shown). When the supply motor rotates, the protective sheet S is pulled out from the supply reel 102, so that the supply reel 102 rotates.

  The feed roller 107 is connected to a feed motor (not shown). By rotating the feed motor, the protective sheet S is moved and supplied to the pressure-bonding head unit 2. The supply roller 104 is a roller on the supply reel 102 side of the buffer mechanism unit 115, and the feed roller 107 is a roller on the pressure bonding head unit 2 side of the buffer mechanism unit 115.

  The sheet break detection sensor 114 is a sensor for detecting sheet break.

  The buffer mechanism unit 115 is a part that functions as a buffer when the protective sheet S is sent in the sheet supply unit 1. The buffer mechanism 115 will be described in detail below.

  The buffer mechanism 115 has a plurality of sheet rollers 106 as fixed rollers whose positions are fixed, and a sheet roller 110 as a moving roller on a linear block 105 as a moving member mounted on two linear shafts 109. This is a mechanism for providing a two-peak routing for the protective sheet S.

  The linear block 105 moves up and down depending on the remaining amount of sheets in the buffer mechanism 115.

  A sensor dog 111 is installed in the linear block 105, a standard position sensor 113 as a first position sensor detects the position of the linear block 105, and a control unit (described later) detects that the linear block 105 is the first block. The supply motor is controlled so as to approach the standard position which is the position. That is, in FIG. 2, when the linear block 105 is below the standard position sensor 113, the supply motor is stopped to raise the linear block 105 until it is detected by the standard position sensor 113, and the linear block 105 is above the standard position. In some cases, the supply motor is rotated and the protective sheet S is supplied to lower the linear block 105 until it is detected by the standard position sensor 113.

  On the other hand, the sheet storage end sensor 112 as the second position sensor is a sensor for detecting that the protective sheet S has run out in the sheet supply unit 1, and the supply of the protective sheet S from the supply reel 102 is lost. When the linear block 105 reaches the position of the sheet storage end sensor 112, a warning is given by a sheet depletion warning lamp, a display panel (not shown) or the like, and the operation of the crimping head 204 of the crimping head unit 2 is stopped.

  While the end detection sensor 103 does not detect the end of the protection sheet S, the supply roller 104 is operable by the supply motor. When the end detection sensor 103 detects the end of the protection sheet S, the supply motor stops. The supply of the protective sheet S by the supply roller 104 is stopped.

  The protective sheet S is sent to the pressure-bonding head unit 2 by the rotation of the feed roller 107, whereby the linear block 105 is raised. As a result, the standard position sensor 113 cannot detect the sensor dog 111. On the other hand, until the standard position sensor 113 detects the sensor dog 111, the control unit rotates the supply roller 104 by the supply motor, the protective sheet S is supplied to the buffer mechanism unit 115, and the linear block 105 is lowered. As a result, the standard position sensor 113 detects the sensor dog 111. Usually these are repeated.

  As described above, the protective sheet S sent to the crimping head unit 2 is sent to the crimping head unit 2 and used to protect the mounting member and the crimping blade 214. Finally, the sheet collecting unit shown in FIG. Sent to 3. Here, the protective sheet S sent by the supply unit 1 is sent to a collecting means (not shown) by the rotation of the collecting roller 301 directly connected to the collecting motor.

  When the end detection sensor 103 detects the end of the protective sheet S, the control unit warns by a sheet out warning lamp, a display panel (not shown), or the like. In this case, the control unit stops the rotation of the supply motor, but does not stop the operation of the crimping head 204 of the crimping head unit 2.

  The worker recognizes this warning and performs the work of adding the protective sheet S. That is, the supply reel 102 after the supply of the protective sheet S is removed, the supply reel 102 is replaced with a new one, and the protective sheet pulled out from the supply reel 102 replaced with the last of the previous protective sheet S is removed. Affix the tip with connecting tape.

  The time required for this work is about 5 minutes in actual measurement. If the worker does not perform this work, the protective sheet S is not supplied from the supply reel 102 as described above, and the sheet storage end sensor 112 detects the rise of the linear block 105, and the operation of the crimping apparatus is performed. (It is estimated that this time is about 30 minutes in the scale of the apparatus currently used), but if the protective sheet S is replaced by then, the protective sheet S is not stopped without stopping the apparatus. Can be added.

  Further, FIG. 2 shows a two-mountain routing as an example, but the working time can be further ensured by increasing the number of peaks and increasing the amount of stored sheets.

  The drive motor for the feed roller 107 and the collection roller 301 needs a servo motor so that the sheet feed amount can be controlled. However, the drive motor for the supply roller 104 is controlled by turning on / off the standard position sensor. But you can.

  As shown in FIG. 3, each part of the crimping apparatus is connected to the control unit 400 and its operation is controlled.

  The crimp blade driving mechanism 410 is a mechanism for driving the crimp blade 214. The transport mechanism 420 is a mechanism that transports the display panel substrate.

  The supply motor 430 rotates the supply roller 101, the supply motor 431 rotates the supply roller 104, the feed motor 432 rotates the feed roller 107, and the collection motor 433 rotates the collection roller 301 based on instructions from the control unit 400. Make it work.

  The end detection sensor 103 reports to the control unit 400 when the end of the protective sheet S is detected.

  The standard position sensor 113 reports to the control unit 400 when the sensor dog 111 attached to the linear block 105 has reached the standard position.

  The sheet storage end sensor 112 reports to the control unit 400 when the sensor dog 111 attached to the linear block 105 comes to a position where it can be seen that there are no stored sheets.

  The sheet break sensor 114 reports to the control unit 400 when a sheet break occurs in the protective sheet 114.

  The out-of-sheet warning lamp 440 is turned on according to an instruction from the control unit 400 when the end detection sensor 103 detects a sheet end.

  The sheet depletion warning lamp 441 is turned on according to an instruction from the control unit 400 when the sheet storage end sensor 112 detects that the protective sheet S in the sheet supply unit has run out.

  Although the control is somewhat complicated, the sheet out warning and the sheet exhaustion warning may be performed by providing a display device and displaying the characters and icons on the control unit 400.

Next, sheet feeding of the crimping apparatus will be described with reference to FIG.
FIG. 4 is a diagram illustrating only a relevant part of the crimping apparatus in order to explain the state of sheet feeding in the S direction.
FIG. 5 is a diagram for explaining a use state in the protective sheet S. FIG.

  Only the S (Source) direction (the long side of the panel) will be described below, but the same applies to the G (Gate) direction (the short side of the panel).

  The protective sheet S sent out from the sheet supply reel 102 is guided to the guide roller 50a through the buffer mechanism 115, the feed roller 107, and the guide rollers 120f to 120h. The guide roller 50a is disposed on the side of the lower blade. The rotation axis of the guide roller 50a is inclined with respect to a direction that is parallel to the horizontal direction and orthogonal to the direction in which the plurality of crimping blades 214 are arranged.

  The inclination changing portion 60 in the center of the drawing is composed of two pressing rollers 60a and 60b and a taper roller 60c. The pressing rollers 60a and 60b are formed in a columnar shape and press the protective sheet S facing the crimping blade 214 so as not to be displaced upward. Thereby, the protective sheet S facing the crimping blade 214 is maintained in a state substantially parallel to the horizontal direction. The rotation shafts of the pressing rollers 60a and 60b are substantially orthogonal to the width direction of the protective sheet S.

  The taper roller 60c is disposed above the pressing rollers 60a and 60b. The rotation axis of the taper roller 60c is oriented in a direction perpendicular to the direction in which the crimping blades 214 are arranged. The diameter of the tapered roller 60c is continuously reduced toward the front side of the pressure-bonding head portion 2. The pressing rollers 60a and 60b and the taper roller 60c reverse the inclination angle of the protective sheet S guided by the guide roller 50a and guide it to the guide roller 50b.

  As described above, the crimping apparatus according to the present embodiment employs a method in which the protective sheet S is sent while being tilted by the θ direction in the direction in which the crimping blades 214 are arranged (relative to the X direction).

  Therefore, as shown in FIG. 5, it can be used efficiently over almost the entire surface of the protective sheet S, and the feeding amount for each press-bonding can be reduced.

  Therefore, by adopting this oblique sheet feeding method, the buffer amount of the sheet supply unit 1 can be reduced, and the number of sheet rollers 106 and 110 can be reduced. Therefore, there is an effect that it is possible to shorten the time when the protective sheet S is set in the sheet supply unit 1 during the initial setup.

Next, another form of the buffer mechanism will be described with reference to FIG.
FIG. 6 is a diagram illustrating another form of the buffer mechanism unit in the sheet supply unit.

  The buffer mechanism 115 described above has a chevron routing between the sheet rollers. The buffer mechanism 115 ′ has an opening slightly wider than the width of the protective sheet S and a length in a direction perpendicular to the opening plane. A stock portion 80 having a thickness is provided. The stock unit 80 stores the protective sheet S by sucking air from an intake port 81 provided on the lower side.

  The intake port 81 is connected to an air suction mechanism 82 such as a vacuum pump.

  Guide rollers 85 and 86 for guiding the protective sheet S are provided at both ends of the opening of the stock unit 80.

  The protective sheet S sent from the supply roller 104 to the guide roller 86 enters the inside of the stock unit 80 through the opening of the stock unit 80, and again passes through the opening of the stock unit 80 and the guide roller 85 and is not shown. It is sent to the feed roller. At this time, the air suction mechanism 82 is operated to suck the inside of the stock unit 80 from the intake port 81, and the supply motor, feed motor, standard position sensor, sheet storage sensor, etc., as in the embodiment of FIGS. And the protection sheet S can be stored inside the stock unit 80 by controlling the feeding of the protection sheet S by the control unit.

  As described above, in the present embodiment, the main pressure bonding apparatus used in the main pressure bonding process has been described as an example. However, the pressure bonding apparatus used in the PCB pressure bonding / mounting process can also be applied.
