Description

  The present invention relates to a display panel laminating apparatus and a laminating method, and more specifically, when an adhesive is dropped on a panel provided with a barrier to laminate another panel, the display area is first pressed from above and below. In particular, the present invention relates to a panel laminating apparatus and a panel laminating method in which an adhesive is spread in the direction of the barrier and subsequently the barrier portion is pressed to be laminated.

  Electronic paper having a structure in which liquid crystal is injected and sealed between plastic or glass sheets is being put to practical use. This electronic paper is expected to be a new electronic medium because the display content can be electrically rewritten and color display is also possible.

  Furthermore, when plastic film is used for electronic paper, it can be bent as long as it is within a certain range of curvature. Taking advantage of its thinness and lightness, it can be used to hang trains, post ads attached to telephone poles, etc. It can be used to display information such as POP advertisements.

  One of the display principles capable of full color display is one using a cholesteric liquid crystal material. This is because the cholesteric liquid crystal reflects only a specific wavelength, and when sunlight enters the liquid crystal, voltage is applied to the liquid crystal layers of each color to control the red, green, and blue wavelengths. Full color is realized. Therefore, full-color electronic paper by this method is made so that three panels of red, green, and blue are laminated to form one electronic paper.

  When bubbles are present between the panels, the display quality is adversely affected by diffuse reflection. The same applies to the mixing of dust. For this reason, at the time of manufacturing a panel, a laminating process for laminating a plurality of panels and reinforcing members is generally performed in vacuum. By creating a vacuum, it is possible to minimize the mixing of bubbles, and even if only a few bubbles remain, the bubbles are pressed down to the atmospheric pressure when released to the atmosphere and become so fine that they cannot be recognized by the naked eye. There is little to be. However, when the panels are stacked in a vacuum, the stacking apparatus including the vacuum apparatus becomes large and expensive.

  Generally, the panel is laminated by dropping an adhesive between two panels and pressing both panels. FIG. 7 shows a method for laminating the panel as an example of the prior art. As shown in FIG. 7A, the panel laminating apparatus has an upper surface adsorption plate 10 that adsorbs and holds one panel 40 to be laminated, an upper surface adsorption support base 11 that supports the upper surface adsorption plate 10, and another panel 50. The lower surface adsorption plate 20 that adsorbs and holds the lower surface adsorption plate 20, the lower surface adsorption support base 21 that supports the lower surface adsorption plate 20, and the stage mechanism 30 that moves the lower surface adsorption plate 20 and the lower surface adsorption support base 21 up and down. The position of the upper surface suction plate 10 is fixed, and the lower surface suction plate 20 moves upward to press the panels 40 and 50 and stack them. The surfaces of the upper surface suction plate 10 and the lower surface suction plate 20 that hold the panels 40 and 50 are both flat, and a vacuum suction hole (not shown) is formed on the plane.

  FIG. 7A shows a state before lamination, and a frame-like barrier 51 that blocks the spread of the adhesive 60 is formed on the panel 50 held on the lower surface adsorption plate 20. The adhesive 60 has been dropped inside the barrier 51. The barrier 51 is formed of a resin that is cured by visible light, for example, around the outside of the display region, and the barrier has a width of 150 to 200 μm and a height of 100 μm or less. The panels 40 and 50 are each filled with liquid crystal between plastic films. For example, the panel 40 is a red panel that constitutes an electronic panel, and the panel 50 is a green panel.

  FIG. 7B shows a state where the stage mechanism 30 is raised and the panel 40 and the panel 50 are pressed by the upper surface suction plate 10 and the lower surface suction plate 20. When the adhesive 60 before lamination is dripped as shown in FIG. 7A, the adhesive 60 swells in the approximate center due to the viscosity of the adhesive 60. However, the adhesive 60 is pressed by the upper and lower suction plates. 60 extends toward the barrier 51. The spread adhesive 60 is cured, and the panel 40 and the panel 50 are laminated. In the case of full-color electronic paper, three panels are stacked, so another panel is stacked on the stack of two panels.

  As a proposal for stacking panels, a method for preventing air bubbles from being mixed between panels has been proposed.

In this proposal, when a liquid crystal panel and a polarizing film are bonded together in a vacuum, the polarizing film is opposed to the liquid crystal panel, and then the atmosphere is introduced and the polarizing film is pressed against the liquid crystal panel with the force of atmospheric pressure. To do. Adhesion is performed at once by applying an adhesive to the polarizing film in advance (Patent Document 1).
JP 7-318919 A

  As described above, when air bubbles enter between the panels to be laminated, irregular reflection occurs at that portion, and the display quality deteriorates. For this reason, it is common to perform panel lamination in a vacuum, but the size of the apparatus increases and the cost becomes high, which puts pressure on the cost. For this reason, it is desirable to work in the atmosphere.

  Further, if the amount of the adhesive and the pressing method at the time of stacking are not appropriate in the stacking of the panels, an unextended region of the adhesive is generated near the inside of the barrier. There is no problem if the unexpanded area is outside the display area, but if it is within the display area, light is reflected in that part in the same manner as bubbles, and display quality is degraded. FIG. 8 shows an example of an unexpanded area in the vicinity of the barrier, and an unexpanded area 61 that enters the display area 70 of the panel 50 is a problem in display quality. In FIG. 8, another unextended area is seen on the lower side.

  In addition, when the panels are stacked, the adhesive flows out from between the panels, and the adhesive may wrap around the display surface and electrode portions formed on the panel, causing the display surface to become dirty or have a problem of current conduction.

  The present invention relates to a panel laminating apparatus in which uniform adhesive spreading is performed while the laminating operation is performed in the atmosphere, there are no bubbles or unexpanded areas in the display area, and the sticking out of the adhesive can be suppressed.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. The panel laminated in this embodiment is a panel having the same structure as that described with reference to FIGS. That is, a frame-shaped barrier that blocks the spread of the adhesive is formed around the outer periphery of the display area of one of the two panels. The other panel to be bonded is not formed with a barrier, and is dropped inside the barrier so that the adhesive is covered from above.

  FIG. 1 shows the configuration of the main part of the panel laminating apparatus according to the present invention and its operating principle. The main part is composed of an upper surface suction plate 300, a lower surface suction plate 400 and a barrier pressing plate 500. FIG. 1A shows a state before bonding, and the upper surface adsorption plate 300 adsorbs and holds one panel (herein referred to as a first panel) with the adhesive surface of the panel facing down. ing. As shown in FIG. 1A, the planar outer shape of the upper surface suction plate 300 is sufficiently larger than the outer shape of the first panel 40, and the entire back surface of the first panel 40 is sucked and held.

  The lower surface adsorption plate 400 adsorbs and holds another panel (referred to herein as a second panel) on which a barrier is formed from the back surface with the barrier facing upward. The size of the planar outer shape of the lower surface adsorption plate 400 is the same as the display area of the panel, but slightly smaller than that, and the lower surface adsorption plate 400 adsorbs and holds the display area portion of the second panel from the rear surface. Is in a free state. The back surface of the lower surface suction plate 400 is connected to a stage mechanism 410 that moves up and down. Further, the adhesive 60 is dripped inside the barrier 51 of the second panel 50.

  The barrier pressing plate 500 has a frame shape when viewed from above, and is arranged so that the lower surface adsorption plate 400 is accommodated inside the frame. The height of the pressing surface of the barrier pressing plate 500 is lower than the height of the suction surface of the lower surface suction plate 400. Further, the lower side of the barrier pressing plate 500 is in contact with the stage mechanism 410 as shown in FIG. 1A, and when the stage mechanism 410 is lifted, it is lifted together with the lower surface suction plate 400. Further, the barrier pressing plate 500 can be moved upward from the surface in contact with the stage mechanism 410 by a lift mechanism (not shown). However, the lower part of the barrier pressing plate 500 is in contact with the stage mechanism 410 at the stage of FIG.

  1B, the stage mechanism 410 ascends from the state of FIG. 1A as indicated by the arrow, the second panel 50 comes into contact with the first panel 40, and the lower surface suction plate 400 presses the display area. The state where the adhesive 60 is spread is shown. At this time, since the portion is in a free state from the barrier region of the second panel 50 to the end of the panel as described above, the air is bent and the air passes through the barrier 51 due to the spreading of the adhesive 60. Extruded beyond.

  When the adhesive 60 is sufficiently spread, the barrier pressing plate 500 is lifted by a lift mechanism (not shown) until the height of the surface of the barrier pressing plate 500 coincides with the height of the surface of the lower surface suction plate 400 (FIG. 1C). And the barrier region of the second panel 50 is pressed from the back side. FIG.1 (c) has shown the state which is pressing this barrier area | region.

  It is divided into two stages of FIG. 1B and FIG. 1C. First, the display area is pressed, and then the barrier area is pressed in addition to the display area, so that the air between the panels can easily escape and the adhesive. Can spread evenly. For this reason, generation | occurrence | production of a bubble and an unexpanded area | region is suppressed.

  Next, a barrier is formed in a semi-cured state, and when the barrier region is pressed by the barrier pressing plate 500 shown in FIG. An example will be described with reference to FIG. Here, introduction of a visible light source is provided in the upper surface adsorption plate 300, a hole 310 is formed in the upper surface adsorption plate 300, and an emission head 320 that guides visible light from the lamp light source using an optical fiber is disposed in the hole 310. is doing. Visible light irradiates the barrier region of the second panel 50 from the hole 310 through the first panel 40. As shown in the figure, the holes 310 are provided at five locations on one side of the longitudinal barrier, and visible light is spot-irradiated therefrom. In addition, a transparent glass or plastic window 330 is provided at the bottom of the hole 310 so that the window 330 is in contact with the first panel 40 and receives the pressure from below by the barrier pressing plate 500. In FIG. 2, the lamp 320 is arranged with respect to the barrier in the longitudinal direction, but the lamp 320 may be arranged with respect to the barrier in the short direction. Further, although five light sources are provided for one side, a single elongated tubular lamp may be disposed on each side.

  Subsequently, the installation of a detector that detects that the second panel 50 is in contact with the first panel 40 and detects the amount of application when the second panel 50 is pressed against the first panel 40 will be described. To do. FIG. 3A shows an example in which a concave portion is formed on the upper surface of the stage mechanism 410 and a detector 800 using a load cell or the like is disposed therein. That is, the detector 800 is disposed between the stage mechanism 410 and the lower surface suction plate 400 in order to detect the pressure applied to the lower surface suction plate 400. More specifically, the upper detection side of the detector 800 is in contact with the lower surface suction plate 400, and the bottom of the detector 800 is supported by the stage mechanism 410 with an elastic member (not shown) so that accurate pressure can be detected. .

  FIG. 3B shows an example of pressure detection of the detector 800 in FIG. First, the raising of the stage mechanism 410 is started at time “t1”. While the stage mechanism 410 is moving up, the detection pressure of the detector 800 is “0”. At time “t2”, the detector 800 detects the pressure and the pressure value increases. This rise is when the second panel 50 held by suction by the lower surface suction plate 400 comes into contact with the first panel 40. The rise of the stage mechanism 410 from the time “t2” causes the second panel 50 to start pressing against the first panel 40. By this pressing, the adhesive 60 spreads between the first and second panels. The rising of the stage mechanism 410 is stopped at a time “t3” when the pressing pressure becomes a predetermined amount (pressing application amount). Subsequently, the barrier pressing plate 500 is raised to press the barrier region. During this time, the pressure of the detector 800 is maintained at a constant pressure. At a time “t4” after a predetermined time, the suction of the upper surface suction plate 300 is released, and the stage mechanism 410 and the barrier pressing plate 500 are lowered while holding and holding the stacked panels. The detector 800 returns to “0” at time “t4”.

  Next, an example in which the above-described upper surface adsorption plate 300, lower surface adsorption plate 400, and barrier pressing plate 500 are incorporated into the panel laminating apparatus 100, and the operation flow thereof will be described with reference to FIGS.

  FIG. 4 is a perspective view of the panel laminating apparatus 100, in which a stage mechanism 410 is installed on the base plate 200, and a lower surface adsorption plate 400 and a barrier pressing plate 500 are disposed on the stage mechanism 410. The barrier pressing plate 500 has a frame shape as shown in FIG. 4, and a lower surface suction plate 400 is disposed inside the frame, and the height of the pressing surface of the barrier pressing plate 500 is the height of the suction surface of the lower surface suction plate 400. About 200 μm lower than the height. The stage mechanism 410 can be moved up and down by an air slider that is not visible in the figure, and the stage mechanism 410 raises and lowers the barrier pressing plate 500 together with the lower surface suction plate 400 in the Z direction in the figure. Further, when the barrier pressing plate 500 presses the barrier region, the barrier pressing plate 500 is lifted by a lift mechanism not visible in the drawing to press the barrier region. In addition, although the lamp | ramp 320 and the detector 800 which irradiate visible light are not visible from this figure, they are each installed.

  Further, the panel laminating apparatus 100 includes a dispenser 600 and can drop a predetermined amount of the adhesive 60 inside the barrier of the second panel 50 sucked and held on the lower surface suction plate 400. The dispenser 600 can move in the X direction and the Y direction in the figure, and moves above the lower surface suction plate 400 only when the adhesive 60 is dropped. Further, the panel laminating apparatus 100 includes cameras 700 and 710 for panel alignment.

  The upper surface suction plate 300 is disposed at the uppermost part of the panel laminating apparatus 100 and is slidable in the Y direction in the figure by an air slider 720 and a slide guide 730. When the first panel 40 is transferred from the lower surface suction plate 400 and when the first and second panels are pressed, the first panel 40 is slid forward of the panel laminating apparatus 100, and otherwise, the first panel 40 waits backward.

  FIG. 5 explains the operation flow of the panel laminating apparatus 100 shown in FIG. First, the first panel 40 is aligned and held on the lower surface suction plate 500. At this time, the adhesive surface of the first panel is held downward. Subsequently, the upper surface suction plate 300 waiting in the rear is slid forward and moved above the lower surface suction plate 400. The lower surface suction plate 400 is lifted, and when the first panel 40 comes into contact with the lower surface suction plate 400, the lower surface suction plate 400 stops rising, the lower surface suction plate 400 is turned off, and the upper surface suction plate 300 is turned on. To do. Thereby, the 1st panel 40 is delivered from the lower surface adsorption | suction board 400 to the upper surface adsorption | suction board 300 (S10-S30).

  Subsequently, the upper surface suction plate 300 is slid rearward, and the second panel 50 is aligned with the lower surface suction plate 400 and held by suction. The dispenser 600 is moved from the standby position to the center of the lower surface suction plate 400, and the adhesive 60 is dropped (S40, S50).

  The dispenser 600 is returned to the standby position, the upper surface suction plate 300 is slid forward again, and the lower surface suction plate 400 is raised at a predetermined speed. When the detector 800 detects contact with the first panel 40, it switches to a slight increase and spreads the adhesive 60. When the detector 800 detects a predetermined pressure application amount, the lower surface suction plate 400 stops rising (S60-S100).

  The barrier pressing plate 500 is raised at a slow speed and pressed with a predetermined pressing application amount. Then, the visible light source of the upper surface adsorption plate 300 is turned ON for a predetermined time to fully cure the barrier (S110, S120).

  The adsorption of the upper surface adsorption plate 300 is turned off, the lower surface adsorption plate 400 and the barrier pressing plate 500 are lowered, and the adsorption of the lower surface adsorption plate 400 is turned off to remove the stacked panel from the lower surface adsorption plate 400 (S130).

The removed panel is placed in a lamp house, for example, and the adhesive 60 is cured.
