Description

  The present invention relates to a sheet glass bonding method for bonding a bonding object such as a functional sheet or another sheet glass to one surface of a sheet glass, and a sheet glass bonding apparatus. Hereinafter, in this invention, the plate glass by which the bonding target is bonded is called base glass.

  As this type of bonding apparatus, for example, the bonding apparatus of Patent Document 1 is known. In this case, an adhesive layer having rubber-like elasticity is formed on one side of the base glass, and then a polycarbonate plate is bonded. Specifically, an adhesive sheet whose front and back are covered with a release film is prepared in advance, and the adhesive sheet is bonded to one side of the base glass while peeling the release film on one side to form an adhesive layer. Next, the base glass is placed on the base plate with the adhesive layer on the upper surface, and the polycarbonate plate is slanted in a state in which the adhesive start end is in contact with the adhesive layer and the adhesive end is lifted away from the adhesive layer. The polycarbonate plate is bonded to the base glass by pressing the polycarbonate plate against the base glass with a roller while moving the roller toward the end of adhesion, preventing bubbles from forming on the bonding surface. ing.

  A similar laminating apparatus is also disclosed in Patent Document 2. There, the thin glass that is the object to be bonded to the base glass is bonded and fixed via an ultraviolet curable resin, but the thin glass is vacuum-adsorbed with a bonding jig and held in a downwardly curved shape for bonding. Different from the previous bonding device. The thin glass held in the downward projecting curved shape by the bonding jig is bonded and fixed by pressing the bonding jig against the base glass with a pressure roller from the bonding start end toward the bonding end.

  Patent Document 3 also discloses a bonding apparatus that vacuum-sucks a plate glass to be bonded and holds it obliquely. In this case, the glass sheet is adsorbed and held obliquely by the joint action of the conveyor belt and the adsorption chamber disposed on the inner surface of the conveyor belt.

JP 2001-30420 A (paragraph number 0021, FIG. 2) JP 2000-53453 A (paragraph numbers 0019 to 0024, FIG. 1) Japanese Patent Laid-Open No. 2-9733 (lower right column on page 3, FIG. 2)

  According to the bonding apparatuses of Patent Documents 1 to 3, theoretically, there should be no room for air bubbles to be formed between the base glass and the object to be bonded. The defect rate is high and there is a problem with productivity. Although it depends on the object to be bonded, the glass laminate that has become poorly bonded peels off the object to be bonded, and then only the base glass is reused and the object to be bonded is discarded. For example, when a functional sheet such as a polarizing sheet or an antireflection film is bonded to the outer surface of a liquid crystal substrate or a plasma display substrate, the functional sheet that has failed to be bonded is peeled off and discarded. By the way, since this type of functional sheet is expensive, the total cost of the functional sheet to be discarded reaches a considerable amount annually, which is a major obstacle to reducing the manufacturing cost of the glass laminate. .

  In all past bonding devices, the bonding start end of the object to be bonded is in contact with the adhesive layer, and the bonding end is supported obliquely or in a curved posture with the adhesive end floating away from the adhesive layer. The object to be bonded is pressed against the base glass with a roller and bonded. In other words, the alignment between the base glass and the object to be bonded is merely aligning both edges at the bonding start end. Therefore, the bonding end of the base glass and the object to be bonded in a state where the bonding has been completed may be greatly displaced, and this type of bonding failure is one of the factors that reduce the productivity of glass laminates. Yes.

  The object of the present invention is to securely bond the object to be bonded and the base glass without generating bubbles, and to bond the object to be bonded and the base glass with high precision, as a whole. An object of the present invention is to provide a sheet glass laminating method and apparatus capable of improving the productivity of a glass laminate and reducing the production cost.

  In the method for laminating a plate glass in the present invention, the base glass G is adsorbed and fixed by a plurality of sets of adsorbers 3 provided on the adjustment table 2, and the object to be bonded F is moved to the movable table 4 at a standby position outside the fixing table 1. Provided on the fixed base 1, the step of adsorbing and fixing, the step of moving the movable table 4 from the standby position to the bonding position, and causing the bonding object F to face the base glass G through the vertical gap E, The position deviation between the bonding object F and the base glass G is optically detected by the deviation detection device 20, and the position of the adjustment table 2 is adjusted by the position adjustment device 6 according to the output signal from the deviation detection device 20. The step of positioning the bonding object F and the base glass G, and the adhesive roller 5 is moved from the standby position to the pressing position to press the bonding start edge of the base glass G against the bonding object F, and the bonding roller 5 is bonded from the bonding start edge. Termination And the process of pressing and bonding the base glass G to the object F to be bonded. In the process of moving the bonding roller 5 from the bonding start end toward the bonding end, the bonding roller 5 precedes the bonding movement. The base glass G is pressed and bonded to the bonding object F while each adsorbing body 3 is retracted from the adsorption position to the retracted position.

  The plate glass laminating apparatus according to the present invention includes a fixing table 1, an adjustment table 2 supported by the fixing table 1 so as to be position-adjustable, and a plurality of sets of adsorbers that are provided on the adjustment table 2 and adsorb and fix the base glass G 3, a movable table 4 that adsorbs and fixes the bonding target F, and an adhesive roller 5 that presses the base glass G against the bonding target F. The movable table 4 is attached to the standby position located outside the fixed base 1 and the base glass G to which the adhering and fixing object F is adsorbed and fixed by the adsorbent 3 via the vertical gap E. It is supported so as to be able to reciprocate between the joint positions, and is configured so that it can be locked and fixed to the fixed base 1 at the bonding position so as to be immovable. The fixing table 1 is configured to adjust the position of the adjustment table 2 according to the displacement detection device 20 that optically detects the displacement between the base glass G and the bonding target F and the output signal from the displacement detection device 20. A position adjusting device 6 is provided. The adsorbing bodies 3 that adsorb and support the base glass G reciprocate between an adsorbing position for adsorbing and holding the base glass G and a retreating position that separates from the base glass G and retreats outside the transition locus of the bonding roller 5. It is supported by the adjustment table 2 so that it can be displaced. The bonding roller 5 can reciprocate up and down between a standby position below the base glass G and a pressing position where the bonding start edge of the base glass G is pressed against the bonding target F, and is bonded from the bonding start edge of the base glass G. It is provided so as to be movable in a state where the pressing position is held over the end. Therefore, prior to the bonding roller 5 moving from the bonding start end toward the bonding end, the base glass G is bonded to the bonding target F while sequentially switching the respective adsorbers 3 from the suction position to the retracted position. It is characterized by that.

  The adsorbing tool 15 of the adsorbing body 3 is configured to be able to reciprocate between an adsorbing position and a separation position that descends from the adsorbing position and separates from the base glass G.

  A breathable silk screen 30 is stretched over the adjustment table 2, and an adsorbing body 3 for adsorbing and fixing the base glass G and an adhesive roller 5 are disposed on the lower surface side of the silk screen 30. The adhesion roller 5 press-bonds the base glass G to the bonding object F through the silk screen 30.

  In the laminating method of the plate glass which concerns on this invention, the bonding object F adsorbed and fixed by the movable table 4 and the base glass G adsorbed and fixed by the plurality of sets of adsorbing bodies 3 on the adjustment table 2 are interposed via the vertical gap E. Then, the positional deviation between the bonding object F and the base glass G is detected by the deviation detection device 20, and the position adjustment device 6 is driven according to the output signal from the deviation detection device 20 to adjust the adjustment table 2. By adjusting this, the bonding object F and the base glass G can be positioned with high accuracy. Further, in the state where the bonding roller 5 is moved from the bonding start end toward the bonding end in a state where the bonding start end of the base glass G is pressed against the bonding target F, each adsorbent is preceded by the bonding movement of the bonding roller 5. The base glass can be pressed and bonded to the G bonding target F while retracting 3 from the suction position to the retracted position.

  According to the above bonding method, the base glass G is inclined downward toward the front in the traveling direction of the adhesive roller 5 by the pressing action of the adhesive roller 5 and the adsorption action of the adsorbent 3 at the position closest to the adhesive roller 5. Since the base glass G can be bonded to the bonding target F while maintaining the state in which the base glass G is bonded, the base glass G and the bonding target are reliably prevented from being caught in the bonding surfaces of both. F can always be suitably bonded. Moreover, since the position shift of the base glass G and the bonding target F is corrected by the shift detection device 20 and the position adjustment device 6 and both of the states positioned with high accuracy are bonded by the adhesive roller 5, the bonding is performed. The positional deviation between the base glass G and the bonding target F in the finished state can be cleared. Therefore, according to the bonding method of the plate glass of this invention, it can always bond reliably without the generation | occurrence | production of an air bubble in the state which positioned the bonding object F and the base glass G with high precision, and is laminated | stacked as a whole. Product productivity can be improved and the production cost of glass laminates can be reduced accordingly.

  Even in the sheet glass bonding apparatus of the present invention, in the same manner as described above, the bonding object F and the base glass G are positioned with high accuracy and are always securely bonded without generating bubbles. As a result, the productivity of the glass laminate can be improved, and the production cost of the glass laminate can be reduced accordingly. Moreover, in the bonding apparatus of this invention, main structures, such as the adjustment table 2 and the adhesion | attachment roller 5 which support the adsorption body 3, or the position adjustment apparatus 6 and the shift | offset | difference detection apparatus 20, are collectively arranged on the fixed base 1 side, Using the bonding target F adsorbed and fixed to the movable table 4 as a position reference, the positional deviation between the bonding target F and the base glass G is corrected, and the base glass G is bonded to the bonding roller 5 with the bonding target F as the bonding reference. Since it press-bonds to the bonding object F, the whole bonding apparatus can be reduced in size and compactly compared with the conventional apparatus of this type.

  When the adsorbing tool 15 of the adsorbing body 3 is configured so as to be able to reciprocate between the adsorbing position and the separating position that descends from the adsorbing position and separates from the base glass G, the bonding roller 5 moves toward the bonding end. When the adsorbent 3 is retracted prior to moving, the adsorber 15 is retracted to the separation position, and then the adsorbent 3 is retracted so that the adsorber 15 and its peripheral structure are in contact with the base glass G. Since interference can be surely prevented, it is possible to reliably prevent the base glass G from being displaced by the suction tool 15 and its peripheral structure, that is, to reduce the positional accuracy of the base glass G.

  An air-permeable silk screen 30 is stretched over the adjustment table 2, and an adsorbing body 3 that adsorbs and fixes the base glass G and an adhering roller 5 are arranged on the lower surface side of the silk screen 30. According to the bonding apparatus in which the base glass G is pressed and bonded to the bonding object F through the silk screen 30, the bonding object F such as a functional film having no self-holding property as well as the base glass G is used. Can be adsorbed and fixed in a flush manner with a plurality of adsorbers 3. If this is utilized, both G and F can be bonded in the state which the base glass G was adsorbed and fixed by the side of the movable table 4, and the bonding object F was adsorbed and fixed by the plurality of adsorbing bodies 3. .

(Example) FIG. 1 thru | or FIG. 10 shows the Example of the bonding apparatus of the plate glass which concerns on this invention. 1 and 2, the bonding apparatus is provided on a fixed base 1 made of a frame assembled in a horizontally long rectangular parallelepiped shape, an adjustment table 2 supported by the fixed base 1 so as to be position-adjustable, and the adjustment table 2. Three sets of adsorbent bodies 3, a movable table 4 that adsorbs and fixes the bonding object F, and an adhesive roller 5 that presses the base glass G supported by the adsorbing body 3 against the bonding object F. . An adhesive layer 8 is formed in advance on one surface of the bonding object F, and the outer surface thereof is covered with release paper.

  The adjustment table 2 is composed of a UVW table, and can be adjusted and moved in the left-right direction and the front-rear turning direction by a pair of left and right position adjusting devices 6 provided between the left and right sides of the fixed base 1 and the adjustment table 2. The necessity of adjusting and moving the adjustment table 2 in this way will be described later.

  2 and 3, the adsorbent 3 has a long and long suction frame 10, a swing frame 11 that supports the front and rear ends of the suction frame 10, and an operation that swings the swing frame 11 around the shaft 12. The cylinder 13, the air cylinder 14 that moves up and down the suction frame 10, and a total of six suction tools 15 that are arranged at regular intervals inside the suction frame 10. Each suction tool 15 is connected to a vacuum source (not shown) via a control valve or the like, and can apply a vacuum pressure or block the vacuum pressure according to a programmed operation procedure.

  The adsorbing body 3 is operated by extending and contracting the operation cylinder 13 to thereby move the upper adsorbing position (a position indicated by a symbol A in FIG. 3) and a retreating position (a symbol C in FIG. The position of the suction tool 15 can be extended and retracted by moving the air cylinder 14 back and forth, and the separation position (position indicated by symbol B in FIG. 3) is lowered from the suction position. ) And can be displaced.

  In a state where each adsorption body 3 is switched to the adsorption position, after placing the base glass G on the adsorption frame 10 in accordance with the positioning display on the upper surface of the adsorption frame 10, by applying a vacuum pressure to the group of adsorption tools 15, The base glass G can be sucked and fixed with its lower surface in close contact with the upper surface of the suction frame 10. Therefore, the suction surface at the upper end of the suction tool 15 is slightly protruded from the upper surface of the suction frame 10.

  The movable table 4 is connected to the fixed base 1 via a shaft 17, and the movable table 4 is displaced around the shaft 17 by an operation mechanism (not shown) so that the movable table 4 is moved outwardly from the upper surface of the fixed base 1. The standby position (position shown in FIG. 2 and FIG. 4) and the bonding position where the table surface faces the base glass G that is reversely operated from the standby position and sucked and held by the suction body 3 (see FIG. 5). The position shown in FIG. Inside the movable table 4, an adsorbing tool 18 for adsorbing and fixing the bonding object F is arranged.

  In a state where the movable table 4 is in the standby posture, the bonding target F is placed according to the positioning display provided on the table surface, and the vacuum pressure is applied to the previous suction tool 18, whereby the bonding target F is placed on the table surface. Can be fixed by adsorption. By reversing the movable table 4 in this state around the shaft 17 and switching to the bonding posture, the rotating tip of the movable table 4 is received by the fixed base 1 and the bonding object F is passed through the vertical gap E. The base glass G can be directly opposed. The upper and lower gaps E are appropriately selected depending on the thickness and elastic modulus of the base glass G, but are usually selected within a range of 0.1 to 5 mm. The vertical gap E in this example was 2 mm. Thereafter, in order to prevent the movable table 4 from moving with respect to the fixed base 1, the movable table 4 is locked and held by a lock structure 19 (see FIG. 2) provided on the fixed base 1 so as not to be relatively movable.

  Although the base glass G adsorbed and held by the adsorbent 3 and the bonding object F adsorbed and held by the movable table 4 are roughly positioned, the positional accuracy of both is low and insufficient. Then, the shift | offset | difference detection apparatus 20 is provided in two places of the fixed base 1, and the position shift | offset | difference with the base glass G and the bonding target F is detected optically. The deviation detection device 20 includes a CCD camera, an alignment controller that recognizes a positional deviation from an image of the CCD camera, a focus controller, and a monitor. By driving the previous position adjustment device 6 according to the output signal from the alignment controller and adjusting and moving the adjustment table 2, the base glass G and the object to be bonded F can be accurately aligned with no positional deviation. I have to.

  A positioning mark is displayed in advance on the base glass G and the bonding object F. For example, as illustrated in FIG. 4, a black circle-shaped position display M <b> 2 is displayed on the base glass G, and a circular position display M <b> 1 is displayed on the bonding target F. In the state where the images of both displays are detected by the CCD camera, if there is a positional shift between the base glass G and the bonding object F, the black circle-shaped position display M2 is a circular position as shown in FIG. It is located outside the display M1. Whether the misalignment between the position indications M1 and M2 has increased by recognizing the image in this state with the alignment controller, adjusting and moving the adjustment table 2 with the position adjustment device 6, and recognizing the image again with the alignment controller. , You can see if it decreased. Thereafter, the position adjustment device 6 is driven in such a direction that the deviation can be reduced, and the recognition of the image after the driving is repeated several times, whereby the black circle position display M2 is displayed as shown in FIG. 7B. A state located inside the circular position display M1 is obtained. The base glass G and the bonding target F in this state are positioned with high accuracy, and the deviation amount of both G and F is within a deviation range of 5 μm with respect to the reference position.

  The adhesive roller 5 is supported by a roller base 22 that is guided and supported so as to be capable of reciprocating along the left and right longitudinal directions of the fixed base 1. Further, the adhesive roller 5 is reciprocally moved up and down by an air cylinder 23 provided on the roller base 22, and a standby position below the base glass G (state indicated by an imaginary line in FIG. 8) and an adhesion start end of the base glass G The posture can be changed to a pressing position (a state indicated by a solid line in FIG. 8) that presses the bonding target F. The roller portion of the adhesive roller 5 is made of hard rubber, and the roller portion circumscribes the base glass G in a line contact manner at the pressing position.

  Base glass G and pasting object F are pasted through the following processes. First, as shown in FIG. 4, the base glass G is adsorbed and fixed by the three sets of adsorbers 3, and the bonding target F is adsorbed and fixed to the table surface of the movable table 4 at the same time. In this state, the release paper is removed and the adhesive layer 8 is exposed. The supply of the base glass G and the bonding object F and the removal of the release paper can be performed by an automatic machine, and may be performed manually.

  Next, the movable table 4 is displaced from the standby position to the bonding position, and the bonding object F is directly opposed to the base glass G through the vertical gap E as shown in FIG. In this state, the positional deviation between the bonding object F and the base glass G is optically detected by the deviation detection device 20, and the adjustment table 2 is adjusted by the position adjustment device 6 according to the output signal from the deviation detection device 20. And the bonding object F and the base glass G are positioned appropriately. The details are as described above.

  After the positioning is completed, the adhesive roller 5 is moved upward from the standby position below the base glass G to the pressing position as shown in FIG. 8, and the bonding start edge of the base glass G is pressed against the bonding target F. The base roller G is pressed and bonded to the bonding object F by moving the bonding roller 5 from the bonding start end toward the bonding end. At this time, as shown in FIG. 10, the base glass G is pressed and bonded to the object to be bonded while the adsorbing bodies 3 are retracted from the suction position to the retracted position prior to the pressure bonding operation of the bonding roller 5.

  In a state where the bonding roller 5 is moved upward from the lower standby position to the pressing position and the bonding start edge of the base glass G is pressed against the bonding target F, the base glass G is in a state of being adsorbed and fixed by each adsorbent 3. (See FIG. 8). Therefore, the base glass G draws a gentle S-shape between the position pressed by the adhesive roller 5 and the position adsorbed and fixed by the adsorbent 3 closest to the adhesive roller 5 and the closest position. It will be elastically deformed in a state of being inclined downward toward the adsorbent 3. That is, as shown in FIG. 9, the base glass G is continuously stretched from the position pressed by the adhesive roller 5 toward the front in the traveling direction of the adhesive roller 5, and continuously to the bonding target F. It will be pressed and bonded. As a result, the air that is about to be sandwiched between the bonding surfaces can be forcibly released toward the front in the roller traveling direction by the pressing action of the adhesive roller 5, and therefore, it is ensured that air bubbles are trapped in the bonding surfaces. While being prevented, the bonding object F and the base glass G can always be suitably bonded.

  Corresponding to the start of movement of the adhesive roller 5 from the adhesive start end to the adhesive end, the supply of vacuum pressure to the adsorber 15 of the adsorbent 3 located closest to the adhesive roller 5 is stopped as shown in FIG. Further, the air cylinder 14 and the operation cylinder 13 are operated in order, the suction tool 15 is moved down from the lower surface of the base glass G to the separation position, and the suction body 3 is retracted outside the transition locus of the adhesive roller 5. It is swung to the position. Thus, when the base glass G is bonded to the bonding target F while the three adsorbing bodies 3 are sequentially retracted and moved in response to the bonding movement of the bonding roller 5, bubbles are generated on the bonding surfaces of the two. Since the base glass G and the object F to be bonded can be prepared in a highly positioned state, it is possible to eliminate the bonding failure of the obtained glass laminate and improve the productivity. Product production costs can be reduced. Further, when the adsorber 3 is swung to the retracted position after the adsorber 15 is separated from the base glass G, the adsorber 10 and the adsorber 15 are prevented from contacting and interfering with the base glass G without fail. It is possible to prevent the base glass G from moving by retreating 3 from the suction position.

As can be understood from the above description, the sheet glass bonding method of the present invention can suitably bond both G and F by preparing the base glass G and the bonding object F according to the following steps.
A step of adsorbing and fixing the base glass G with a plurality of sets of adsorbers 3 provided on the adjustment table 2, and adhering and fixing the bonding object F to the movable table 4 at a standby position outside the fixing table 1;
Displacement operation of the movable table 4 from the standby position to the bonding position, the process of causing the bonding target F to face the base glass G through the vertical gap E;
The positional deviation between the bonding object F and the base glass G is optically detected by the deviation detection device 20 provided on the fixed base 1, and the position of the adjustment table 2 is adjusted according to the output signal from the deviation detection device 20. And adjusting the bonding target F and the base glass G,
The bonding roller 5 is moved from the standby position to the pressing position, the bonding start end of the base glass G is pressed against the bonding target F, the bonding roller 5 is moved from the bonding start end toward the bonding end, and the base glass G is bonded. The process of pressing and bonding to F,
In the process of moving the bonding roller 5 from the bonding start end to the bonding end, the base glass is attached to the G bonding object F while each adsorbing body 3 is moved from the suction position to the retracted position prior to the bonding movement of the bonding roller 5. It is characterized in that it is pressed and adhered.

  FIG. 11 shows another embodiment of the bonding apparatus. There, a breathable silk screen 30 is stretched over the adjustment table 2, and an adsorbing body 3 and an adhering roller 5 for adsorbing and fixing the base glass G are arranged on the lower surface side of the silk screen 30. In that case, a vacuum pressure is applied to the lower space covered with the silk screen 30, and an extra screen surface is masked to suck and fix a work such as the base glass G. At the time of bonding, the bonding roller 5 press-bonds the base glass G to the bonding object F through the silk screen 30. If the silk screen 30 is stretched in this way, not only the base glass G but also a bonding object F such as a functional film having no self-holding property can be adsorbed and fixed in a flush manner with a plurality of adsorbents 3. . Therefore, both G and F can be bonded in a state where the base glass G is fixed by suction on the movable table 4 side and the bonding target F is fixed by adsorption by the plurality of adsorbing bodies 3. If necessary, the silk screen 30 can be stretched on the table surface of the movable table 4.

  In addition to the above embodiment, the movable table 4 does not need to be reversed around the shaft 17 to switch between the standby posture and the bonding posture, and after the bonding object F is sucked and fixed on the movable table 4 at the standby position, The movable table 4 can be reversed and further slid sideways to move to the bonding position. The adjustment table 2 may be configured as an XY table. Each of the position indications M1 and M2 may have a shape other than a circle such as a cross-shaped cross line, a triangle, or a star. The adhesive layer 8 can be formed in advance on the base glass G side. The adhesive layer 8 can be formed of an ultraviolet curable resin. In that case, after the base glass G and the bonding target F are prepared by the bonding apparatus of the present invention, the adhesive layer 8 is preferably cured. An arbitrary number of the adsorbents 3 can be provided according to the size of the base glass G, and it is sufficient that there are at least two sets.

  In said Example, although it was made to position the base glass G and the bonding target F using the positioning mark currently formed in each of the base glass G and the bonding object F, the necessity is. Absent. For example, the positioning mark may not be formed on the workpiece such as the base glass G or the bonding target F. Even in such a case, the outer shape such as the side portion or the corner portion of each workpiece, Both can be positioned using the partial shape. In addition, positioning can be performed using the print patterns displayed on both workpieces.
