  The air levitation table 121 has a horizontal upper surface on which many air holes are formed. The air hole communicates with an air device (not shown) via a passage inside the air floating table 121. The air device is an air supply device or an air suction device represented by a pump. By ejecting air from the air holes, the panel P1 can be supported in a floating state. In addition, a part of the air levitation table 121 is ejected from a part of the air holes, and the air is sucked from the other part of the air holes to form a Bernoulli chuck. It can be precisely supported in a floating state.

  The air levitation table 121 extends in the Y direction, which is the conveyance direction of the panel P1. More specifically, it extends across the entire area from the carry-in area R1 to the carry-out area R3 except for the groove 121b. Therefore, the panel P1 and the laminated body LB can be supported in a non-contact manner in the entire region of the manufacturing apparatus A. Two air levitation tables 121 are provided, extend parallel to each other, and are spaced apart in the X direction. A gap in the X direction between the two air levitation tables 121 forms a movement space for the plurality of slide units 123.

The adsorption unit 31 can move on the XZ plane by moving the movable unit 33 in the X direction and moving the rotary unit 32 up and down.

<Position detection unit>
The position detection unit 7 is a unit that is provided in the carry-in area R <b> 1 and detects the position of the panel P <b> 1 whose posture is adjusted and positioned by the adjustment units 14 and 15. Even the panel P1 whose posture is adjusted and positioned by the adjusting units 14 and 15 is not the same shape and accurate square due to the manufacturing accuracy and individual panel differences. Due to the positioning accuracy, they are not in exactly the same posture and position. This becomes a cause of misalignment when the panels P1 and P2 are bonded together. Therefore, the position detection unit 7 detects a more accurate posture and / or position of the panel P1.

  In the case of this embodiment, the position detection unit 7 captures an image of the panel P1 and detects its posture and / or position. The position detection unit 7 may have any configuration as long as the position in the X direction and the Y direction of the panel P1 can be detected. The preferred position detection unit 7 is capable of detecting a wide range of postures and / or positions with high speed and high accuracy without contact.

  The position detection unit 7 includes a camera 71, a slider 72, and a rail member 73. The rail member 73 extends horizontally in the X direction so as to cross over the two rows of air levitation tables 121. The slider 72 engages with the rail member 73 and can reciprocate in the X direction by the guide of the rail member 73 by a drive mechanism (not shown). As the drive mechanism, for example, a linear motor mechanism, a ball screw mechanism, a belt transmission mechanism, or the like can be adopted.

  The camera 71 is supported by a slider 72, and the shooting range is set downward. As a result, the panel P1 on the air floating table 121 can be photographed. In the present embodiment, the camera 71 images a predetermined part of the panel P1 and detects the position thereof, but of course, the camera 71 may be configured to image the entire panel P1.

  In the case of the present embodiment, the site for photographing and detecting the position is a corner of the outer shape of the panel P1. Since the panel P1 is rectangular, the positions of the four corners are detected. In addition, the site | part which image | photographs and detects a position is not restricted to this. For example, as shown in FIG. 4B, it may be a corner portion of the inner edge of the light shielding layer LS. Further, an alignment mark may be attached to the panel P1 in advance, and this mark may be the target.

  A sensor for detecting the moving position of the slider 72 is provided, or the position of the object in the image of the camera 71 is determined from the detection result of the sensor or the position of the slider 72 based on the control amount of the controller by the control amount of the controller of the drive mechanism. As a result, the position of the corner of the panel P1 can be calculated.

  Next, the position detection unit 8 is a unit that is provided adjacent to the carry-in table 5 and detects the position of the panel P <b> 2 sucked by the suction unit 31. Even the panel P2 whose posture is adjusted and positioned by the adjustment units 53 and 54 is not the same shape and accurate square due to the manufacturing accuracy and individual panel differences. Due to the positioning accuracy, they are not in exactly the same posture and position. This becomes a cause of misalignment when the panels P1 and P2 are bonded together. Therefore, the position detection unit 8 detects a more accurate posture and / or position of the panel P2.

  In the case of the present embodiment, the position detection unit 8 captures an image of the panel P2 and detects its posture and / or position. The position detection unit 8 may have the same configuration as the position detection unit 7.

The position detection unit 8 includes two cameras 81, a support member 82 that supports the two cameras 81, and a moving mechanism 83. The support member 82 is a member extending in the Y direction, and cameras 81 are disposed at both ends thereof. The moving mechanism 83 is, for example, an electric cylinder, and moves the support member 82 back and forth in the X direction between the photographing position and the retracted position so as not to interfere with the suction unit 31.

  The two cameras 81 are supported at a distance substantially corresponding to the width of the panel P2 in the Y direction, and the shooting range is set upward. As a result, the panel P2 adsorbed by the adsorption unit 31 can be photographed from below. In the present embodiment, the camera 81 captures a predetermined part of the panel P2 and detects the position thereof. However, the camera 81 may of course be configured to capture the entire panel P2. Further, at least one of the cameras 81 may be provided so as to be movable along the longitudinal direction (Y direction) of the support member 82. As a result, even if the camera 81 has a narrow shooting range, it is possible to deal with panels P2 of various sizes.

  In the case of the present embodiment, the part for photographing and detecting the position is a corner of the outer shape of the panel P2. Two corners can be photographed simultaneously by two cameras 81, and the other two corners can be photographed by rotating the suction unit 31. Since the shooting position is a fixed position, the position of the corner of the panel P2 can be calculated from the image of the camera 81.

  Since the panel P2 is rectangular, the positions of the four corners are detected. In addition, the site | part which image | photographs and detects a position is not restricted to this. For example, it may be a corner portion of a circuit arrangement region (region inside a predetermined width from the outer edge) of the panel P2. Further, an alignment mark may be attached to the panel P2 in advance, and this mark may be the target.

<Control unit>

The control unit 6 includes a processing unit 61 such as a CPU, a storage unit 62 such as a RAM and a ROM, and an interface unit 63 that interfaces an external device and the processing unit 61. The interface unit 63 also includes a communication interface that performs communication with the host computer. The host computer is, for example, a computer that controls the entire manufacturing facility in which the manufacturing apparatus A is arranged.

  The processing unit 61 executes a program stored in the storage unit 62 and controls various actuators 64 based on detection results of various sensors 65 and instructions from a host computer or the like. The various sensors 65 include, for example, a sensor that detects the position of the slide unit 123, a sensor that detects the position of the support 42, a sensor that detects the position and rotation angle of the suction unit 31, and a sensor that detects the position of the slider 72. Various sensors such as a sensor for detecting the position of the support member 82 and an imaging sensor provided in the cameras 71 and 81 are included. The various actuators 93 include, for example, an air device for the air levitation tables 121 and 51, an air device for the adsorption unit 1231, an air device for the adsorption unit 21, and a drive source for various mechanisms.

<Control example>
A control example of the processing unit 61 will be described with reference to FIGS. Here, a series of operations of carrying in the panels P1 and P2 to the manufacturing apparatus A, transporting to the panel P1, bonding the panels P1 and P2, and carrying out the stacked body LB will be described.

  FIG. 6A shows a state immediately before the panel P1 is carried into the carry-in area R1 by an external device. In the two lifting units 13 provided in the carry-in region R1, each pin 131 is located at the raised position. The suction portion 1231 is located at the retracted position at the upstream end position (referred to as the initial position) of the carry-in region R1. The contact portion 141 of the adjustment unit 14 is located at the retracted position. Although not shown, the adjustment unit 15 is the same. Air is ejected from the air holes 12 of the air levitation table 121.

  FIG. 6B shows a state in which the panel P1 is carried into the carry-in area R1 by an external device. The panel P1 is placed on the plurality of pins 131 in a horizontal posture with the surface on which the light shielding layer LS is formed as an upper surface. An adhesive RG is applied in advance to the upper surface of the panel P1 (see FIGS. 9A and 9B).

  Thereafter, as shown in FIG. 6C, the two lifting units 13 provided in the carry-in region R1 lower each pin 131 to the lowered position. Accordingly, the panel P1 is transferred from the plurality of pins 131 to the air levitation table 121. At this time, the panel P1 is not closely attached to the upper surface of the air levitation table 121, but is supported in a floating state slightly raised from the upper surface.

  Next, posture adjustment and positioning of the panel P1 are performed. As shown in FIG. 7A, each adjustment unit 14 is driven, and the contact portion 141 moves to the positioning position. The separation distance in the X direction between the contact portions 141 at the positioning position is substantially equal to the width of the panel P1 in the X direction. For this reason, when the posture of the panel P1 is disturbed, the contact portion 141 contacts the side edge of the panel P1, and the posture and position are adjusted. As a result, of the four sides of the panel P1, the pair of sides located on both sides in the X direction are centered and positioned toward the rail 122 side, and the posture is adjusted in parallel or substantially parallel to the Y direction.

  In parallel, the posture and position in the Y direction with respect to the slide unit 123 of the panel P1 are adjusted. By the drive of the drive unit 152, the contact portion 151 of the adjustment unit 15 moves to the posture and the position adjustment position, respectively. At this time, the postures and positions of the two adjusting units 15 are adjusted so that the positions in the Y direction are the same and parallel to the X direction. One of the two slide units 123 is used for the movement of the panel P1. As shown in FIG. 7B, the suction portion 1231 is raised to the suction position by the lifting mechanism 1234.

As shown in FIG. 8A, the slide unit 123 is moved in the Y direction by a distance set according to the size of the panel P1, and stopped. At this time, the contact portion 1232 of the suction portion 1231 contacts the upstream edge in the transport direction of the panel P1 (the rear edge in the transport direction) and presses the panel P1 toward the downstream side in the transport direction. Then, the conveying direction lower stream side end edge of the panel P1 is brought into contact with each abutment portion 151, the movement of the slide unit 123 is stopped. The distance in the Y direction between the contact portion 1232 and the contact portion 151 when the slide unit 123 is stopped is substantially equal to the width of the panel P1 in the Y direction. Accordingly, at least the front end edge in the transport direction among the end edges on the both sides in the transport direction of the panel P1 (the front end edge and the rear end edge in the transport direction) is positioned at the position of the both contact portions 151 and is parallel to the X direction. The posture is adjusted.

  Thus, the posture adjustment and positioning of the panel P1 are completed. At this stage, air is sucked from the suction holes 1231a of the suction unit 1231, and the panel P1 is suction-held by the suction unit 1231. As shown in FIG. 8B, the contact portions 141 and 151 of the adjustment units 14 and 15 are returned to the retracted position. Before the contact portion 151 is returned to the retracted position, the slide unit 123 is slightly returned to the upstream side to prevent the contact portion 151 from rubbing against the front edge of the panel P1 (edge on the downstream side in the transport direction).

  Next, the position detection unit 7 detects the position of the panel P1. As shown in FIG. 9A, the slider 71 is moved in the X direction, and the movement of the slider 71 is stopped at two positions estimated to be above the corners of the panel P1, and the camera 71 takes a picture. . Thereby, two corners on the front side (downstream side in the transport direction) of the panel P1 are photographed.

  Next, as shown in FIG. 9B, the slide unit 123 is moved by the width in the Y direction of the panel P1, and the panel P1 is sent out by the width in the Y direction. The slider 71 is moved in the opposite direction to that shown in FIG. 9A, and the movement of the slider 71 is stopped at two positions estimated to be above the corners of the panel P1, and the camera 71 takes a picture. As a result, two corners on the rear side (upstream side in the transport direction) of the panel P1 are photographed. In this way, four corners are photographed. Four corner positions are detected from the captured image. As will be described later, the transport amount in the Y direction of the panel P1 is controlled so that the bonding position of the panel P1 and the panel P2 matches from the detection result.

  In parallel with the above processing for the panel P1, the panel P2 is carried into the carry-in table 5 by an external device. The elevating unit 52 is in a state where each pin 521 is located at the raised position, and air is ejected from the air hole 12 of the air floating table 51. Then, as shown in FIG. 10A, the panel P <b> 2 is carried onto the air levitation table 51 as shown in FIG. The panel P2 is placed on the plurality of pins 521 in a horizontal posture with the surface bonded to the panel P1 facing downward. The panel P2 is carried in and transported in this posture, and the panel P1 is loaded and transported with the surface to be bonded to the panel P2 facing upward so that the upper and lower surfaces of the panel P1 and the panel P2 are bonded together when they are bonded together. It is not necessary to “hold” to change

  As shown in FIG. 10B, the pins 521 are lowered to the lowered position by the lifting unit 52. Thus, the panel P2 is transferred from the plurality of pins 521 to the air floating table 51. At this time, the panel P2 is supported not in close contact with the upper surface of the air levitation table 51 but in a slightly floating state.

  Subsequently, the posture adjustment and positioning of the panel P2 are performed. As shown in FIGS. 10B and 10C, the drive units 532 and 542 of the respective adjustment units 53 and 54 are driven, and the contact portions 531 and 541 move to the positioning positions. The distance in the Y direction between the contact portions 531 at the positioning position is substantially equal to the width of the panel P2 in the Y direction. Further, the separation distance in the X direction between the contact portions 541 at the positioning position is substantially equal to the width in the X direction of the panel P2. For this reason, when the posture of the panel P2 is disturbed, the contact portions 531 and 541 come into contact with the side edges of the panel P2, and the posture and position are adjusted. The panel P1 has moved to the holding unit 2.

  Thus, the posture adjustment and positioning of the panel P2 are completed. Thereafter, as shown in FIG. 10D, the drive units 532 and 542 return the contact portions 531 and 541 of the adjustment units 53 and 54 to the retracted position, and the elevating unit 52 raises the pins 521 to the raised position. And the panel P2 is lifted.

  Before and after the posture adjustment and positioning of the panel P2, each pin 521 may be lowered to the lowered position and the panel P2 may be placed on the table 521 to perform processing such as inspection of the panel P2.

  Next, as shown in FIG. 11A, the suction unit 31 is moved onto the carry-in base 5 and lowered onto the panel P2 to suck the panel P2. The panel P2 is adsorbed on the surface (here, the upper surface) opposite to the surface (here, the lower surface) attached to the panel P1. As shown in FIG. 11B, the suction unit 31 is lifted from the carry-in table 5 and the position of the panel P2 is detected by the position detection unit 8. As shown in FIG. 11 (B), the support member 82 is moved to the photographing position by the moving mechanism 83, and the two cameras 81 are positioned almost directly below the two corners of the panel P2 as shown in FIG. 12 (A). To do. By photographing with the two cameras 81, two corners on one side of the panel P2 in the X direction (the upper side in FIG. 12A) are photographed.

  Next, it moves to imaging | photography of two corners in the other side of the X direction of panel P2. The rotation mechanism 32a is driven to rotate the suction unit 31 by 180 degrees as shown in FIGS. 12 (B) and 12 (C). After the rotation is completed, the remaining two corners on the opposite side of the panel P2 (located on the upper side in FIG. 12C and on the lower side in FIG. 12A) are taken by the two cameras 81. Department is filmed. In this way, four corners are photographed. Four corner positions are detected from the captured image. As will be described later, the transport amount in the X direction of the panel P2 is controlled based on the detection result so that the bonding positions of the panel P1 and the panel P2 are matched.

In parallel with the loading of the panel P2, the panel P1 is transported to the processing region R2 and held by the holding unit 2. As shown in FIG. 13A, the holding portion 21b of the holding mechanism 20b is located at a standby position below the upper surface of the air floating table 121 in the groove 121b, and the panel P1 is conveyed thereon. . Holding portion 21 a of the holding mechanism 20a is at a position higher than the panel P1, and stands by at the upstream side in the conveying direction than the panel P1.

  As shown in FIG. 13B, the holding portion 21a of the holding mechanism 20a is lowered into the groove 121a. Subsequently, the moving mechanism 26 (see FIG. 1) is driven to move the support member 24 that supports the holding mechanism 20a, and as shown in FIG. 14A, the holding portion 21a enters the lower side of the panel P1.

  When the panel P1 is moved to a position on each holding portion 21a, 21b, the adsorption of the panel P1 by the adsorption portion 1231 of the slide unit 123 is released, and the slide unit 123 is slightly moved as shown in FIG. Retreat to the upstream position.

  As shown in FIG. 14B, the elevating mechanisms 23a and 23b are driven synchronously to raise the holding portions 21a and 21b synchronously. Thus, the panel P1 is transferred to the holding portions 21a and 21b. Each holding portion 21a, 21b supports the panel P1 from below and is raised to a higher holding position than the roller 41.

  Next, the transport mechanism 3 transports the panel P2 above the panel P1 held by the holding unit 2, and superimposes them. As indicated by a two-dot chain line and arrows A131 and A132 in FIG. 15, the suction unit 31 is moved horizontally onto the panel P1, and the suction unit 31 is lowered to superimpose the panel P2 on the panel P1. At this time, the panel P1 and the panel P2 are slightly in contact with each other or slightly separated from each other, and the panel P2 remains supported by the suction unit 31.

  Next, a pressing force in the thickness direction is applied to the stacked panel P1 and panel P2. First, as shown in FIG. 16A, the roller 41 is moved below the panel P1. The roller 41 is moved to a position slightly upstream of the front end edge in the transport direction of the panel P1 while avoiding a position directly below the retainer 21b so as not to interfere with the retainer 21b later.

  Subsequently, as shown in FIG. 16B, the roller 41 is raised by the elevating mechanism 43, and is brought into contact with the lower surface of the panel P1 and pressed upward (to the panel P2 side). The reaction force of pressing is received by the transport mechanism 3 via the suction unit 31. The panels P1 and P2 are sandwiched between the roller 41 and the suction unit 31. In this state, as shown in FIG. 16C, the roller 41 is moved in the Y direction and moved to a position slightly downstream of the rear end edge in the transport direction of the panel P1 within a range not interfering with the holding portion 21a. Let Since the roller 41 is a free roller, the lower surface of the panel P1 is pressed from the downstream side to the upstream side in the transport direction while rolling. Thereby, the panel P1 and the panel P2 are pressure-bonded and bonded together over the entire surface, and the stacked body LB is obtained. In this state, the stacked body LB is substantially supported by the adsorption unit 31.

  Next, the stacked body LB is transferred from the suction unit 31 to the slide unit 123. First, as shown in FIG. 17A, the roller 41 is lowered by the lifting mechanism 43. As shown in FIG. 17B, the roller 41 is moved to the original position in the Y direction. Further, the slide unit 123 is moved below the stacked body LB. As shown in FIG. 17C, each holding portion 21 of the holding unit 2 is lowered to the standby position, and the suction unit 31 is lowered to place the stacked body LB on the air floating table 121. The stack LB is transferred from the holding unit 31 to the slide unit 123 by restarting the suction at the suction unit 1231 of the slide unit 123 and releasing the suction of the suction unit 31.

  Next, the process proceeds to the step of carrying out the stacked body LB. As shown in FIG. 18, the slide unit 123 is moved to move the stacked body LB onto the lifting unit 13 in the carry-out area R3. The suction unit 31 is moved in the X direction after being lifted to perform the next process. When the stacked body LB reaches the lifting unit 13 in the carry-out area R3, the pins 131 are raised and brought into contact with the lower surface of the stacked body LB, and then the suction of the stacked body LB by the suction portion 1231 of the slide unit 123 is released. To do. As a result, the laminate LB is transferred from the air levitation table 121 to the pins 131 and is ready for delivery to the supply destination device.

  As described above, in the manufacturing apparatus A of the present embodiment, it is possible to continuously and accurately perform the conveyance of both panels (panel P1 and panel P2) to the alignment between the two panels, thereby improving the production efficiency of the stacked body LB. It can be improved.

  Next, with reference to FIGS. 19A to 20B, control of the transport amounts of the panels P1 and P2 will be described. It is preferable that the panel P1 and the panel P2 are bonded to each other with a predetermined positional relationship without positional displacement. Therefore, based on the position detection result of the panel P1 by the position detection unit 7 and the position detection result of the panel P2 by the position detection unit 8, the panels P1 and P2 are positioned at the positions where the panels P1 and P2 are bonded together. In addition, the conveyance amounts of the panels P1 and P2 are controlled. Here, the transport amounts are controlled so that the center positions of the panels P1 and P2 on the XY plane are aligned. Examples of the center position include an intersection of the diagonal lines of the panel, an intersection of a line connecting the midpoints of one facing side of the panel and a line connecting the midpoints of the other facing side, and the like.

  FIG. 19A is an explanatory diagram of transport amount control. The center position of the stacked body LB in the processing region R2 is assumed to be coordinates RP (X, Y). The coordinates RP1 (X, Y1) are ideal coordinates of the center point of the panel P1 whose posture is adjusted and positioned by the adjusting units 14 and 15. When the center point of the panel P1 is at the coordinate RP1, when the panel P1 is transported in the Y direction by the reference distance LY (= Y−Y1), the panel P1 is positioned at the coordinate RP in the processing region R2. Become.

  Similarly, the coordinates RP2 (X1, Y) are ideal coordinates of the center point of the panel P2 whose posture is adjusted and positioned by the adjusting units 53 and 54. When the center point of the panel P2 is at the coordinate RP2, when the panel P1 is transported in the X direction by the reference distance LX (= X−X1), the panel P2 is positioned at the coordinate RP in the processing region R2. .

  If the actual center points of the panels P1 and P2 are deviated from the coordinates RP1 and RP2, the transport amount in the Y direction of the panel P1 may be adjusted by the amount of deviation in the Y direction, and the X direction of the panel P2 It is sufficient to increase or decrease the transport amount of X.

  In order to control the carry amount as described above, coordinate settings in the X direction and the Y direction are necessary. FIG. 19B shows an example. Here, a jig G1 corresponding to the panel P1 and a jig G2 corresponding to the panel P2 are used. The jig G1 and the jig G2 are disposed in the processing region R2 in a state where the bonding positions of the jigs G1 and G2 are closely aligned with each other, and this is the original position.

  Then, the jig G2 is reversely conveyed by, for example, the reference distance LX by the conveyance mechanism 3, and the position is detected by the position detection unit 8. Similarly, the jig G1 is reversely conveyed by the distance LY, for example, by the conveyance mechanism 12, and the position is detected by the position detection unit 7. From the position detection results of the position detection units 7 and 8, coordinates in the X direction and the Y direction can be set.

  As information used for control, for example, the center coordinates of the jig G1 and the jig G2 at the original position are set as the origin. And the coordinate of the center point of the jig | tool G1 is calculated from the coordinate of the four corners of the jig | tool G1 after reverse conveyance by the position detection unit 7, and it is set as the reference | standard center point of the panel P1. Further, the coordinates of the center point of the jig G2 are calculated from the coordinates of the four corners of the jig G2 after the reverse conveyance by the position detection unit 8, and set as the reference center point of the panel P2.

  Alternatively, the coordinates of the four corners of the jig G1 after reverse conveyance by the position detection unit 7 are used as the reference coordinates of the corners, respectively, and the coordinates of the four corners of the jig G2 after reverse conveyance by the position detection unit 8 are used. The reference coordinates of the corners may be used.

  FIG. 20A shows an example of the conveyance amount control. Assume that the coordinates of the center point of the panel P1 are calculated as PC1 (x1, y1) and the coordinates of the center point of the panel P2 are calculated as PC2 (x2, y2) from the position detection results of the position detection units 7 and 8. If the center point after conveyance of the panels P1 and P2 in the processing region R2 is conveyed so as to have the coordinates RC (x1, y2), the panels P1 and P2 can be bonded to each other without misalignment.

  Therefore, the transport amount Ly of the panel P1 can be set as Ly = y2−y1 or Ly = LY + (Y1−y1) − (Y−y2). Further, the transport amount Lx of the panel P2 can be set as Lx = x2-x1 or Lx = LX + (X-x1)-(X1-x2).

  The position detection timing of the panel P1 and the position detection timing of the panel P2 do not necessarily match. When the position detection timing of the panel P1 is earlier than the position detection timing of the panel P2, the transport amount of the panel P1 is set to the reference distance LY, and the transport amount is increased or decreased when the position detection of the panel P2 is completed. It may be. If the panel P1 has already completed the transport of the reference distance LY before the position of the panel P2 is detected, the panel P1 is stopped, and the panel P1 is moved upstream or downstream when the position detection of the panel P2 is completed. In addition, only a necessary amount may be re-conveyed.

  It is assumed that the posture of either the panel P1 or the panel P2 is not appropriate. For example, as shown in FIG. 20B, the panel P2 has a substantially parallel posture with respect to the X direction as shown by a two-dot chain line (if it is tilted by a minute angle θ2 (not shown) ≠ 0 degrees). It is assumed that the panel P1 is inclined at an angle θ with respect to the X direction. Alternatively, the outer shape of the panel P1 may not be a strict square, but may be a parallelogram or a trapezoid. In this case, at least the corresponding sides of the panel P1 and the panel P2 (for example, the side SD1 on the downstream side in the transport direction of the panel P1 and the side SD2 corresponding to the overlap with the side SD1 of the panel P1 in the panel P2) are matched. Is also possible.

  First, the postures of the panels P1 and P2 or the orientations of the sides can be detected from the corner detection results by the position detection units 7 and 8. Further, in the case of the present embodiment, the posture of the panel P2 can be corrected by rotating the suction unit 31 by the rotation unit 32.

  Therefore, for example, as shown in FIG. 20B, the panel P1 tilted by the angle θ is corrected by the correction angle θ ′ (= θ−θ2) necessary for overlapping the panel P2 at the bonding position. By rotating P2, it is possible to match the postures or orientations of the panels P1 and P2. At this time, the coordinates PC2 (x2, y2) of the center point of the panel P2 are replaced with the coordinates PC2 ′ (x2 ′, y2 ′) of the center point after the panel P2 is rotated by the angle θ ′, and then the panel P1. The carry amount Ly and the carry amount Lx of the panel P2 are respectively set. The coordinate PC <b> 2 ′ can be calculated from the coordinate PC <b> 2, the rotation angle, and the coordinates of the rotation center of the rotation unit 32 (designally known coordinates).

  In the present embodiment, the panel P2 is rotatable, but the panel P1 may be configured to be rotatable. Alternatively, both the panel P1 and the panel P2 may be rotatable.

  As described above, in the present embodiment, the bonding positions of the panel P1 and the panel P2 can be matched by controlling the transport amount in the Y direction of the panel P1 and the transport amount in the X direction of the panel P2. A dedicated device for adjusting the alignment position is not required. Therefore, from the conveyance of the panel to the alignment between the panels can be realized with a simpler configuration.

  In this embodiment, the corners and center points of the panel P1 and the panel P2 are used as a reference. However, the method of taking the reference is not limited to this, and may be a part of the side, or may be an alignment mark or the like. Good.

  In the present embodiment, the cover panel and the image display panel are exemplified as the panel P1 and the panel P2. However, the present invention can be applied to other panels. The shapes of the panel P1 and the panel P2 are not limited to a square, and can be various shapes. Although the step due to the presence of the light shielding layer LS has been exemplified as the factor of the step of the resin RG, the present invention can also be applied to the suppression of the step of the resin RG caused by other steps.

  In the present embodiment, the air floating table 121 and the slide unit 123 are combined as the transport mechanism 12 of the panel P1, but the present invention is not limited to this, and various moving mechanisms such as a belt conveyor and a roller conveyor can be adopted. is there.

  In the present embodiment, the transport mechanism 3 is configured to suck and hold the panel P2 by the suction unit 31, but the holding mechanism is not limited to this, and other holding mechanisms such as a mechanical holding mechanism such as a clamp mechanism may be adopted. Good.

  In the present embodiment, the roller 41 is used for pressing the stacked body LB, but other pressing mechanisms can also be used. In addition, the roller 41 is moved in the Y direction when the stacked body LB is pressed, but the stacked body LB may be moved in the Y direction. Furthermore, although it was set as the structure which contact | abuts the roller 41 to the panel P1 lower surface, it is good also as a structure which supports the laminated body LB from the lower side and presses from the upper surface side of the panel P2 to the panel P1 side.

  In the present embodiment, the panel P1 is held by the holding unit 2 as a holding mechanism, and the panel P1 is mounted on the holding portions 21a and 21b. However, other holding mechanisms such as a mechanical holding mechanism such as a suction holding mechanism and a clamping mechanism may be used. It can be adopted.

Second Embodiment
When pressing the panel P1 to the panel 2 side by the roller 41, it is preferable to press the panel P1 so that bubbles are not mixed as much as possible. Therefore, the panel P <b> 1 may be tilted and held so as to assume a horizontal posture as the roller 41 moves. FIGS. 21A to 21D show an example.

  First, as shown in FIG. 21A, the panel P1 is held obliquely so that the upstream end E2 in the transport direction is farther from the panel P2 than the downstream end E1 in the transport direction. In other words, the end E1 closer to the pressing start position by the roller 41 is brought closer to the panel P2, and the end E2 closer to the pressing end position is held away from the panel P2. In the example of the figure, the height difference h is generated between the end portions E1 and E2 by changing the height of the holding portions 21 and 21.

  Next, as shown in FIG. 21B, pressing by the roller 41 is started. As the roller 41 moves, the holding portion 21 on the end E2 side is raised (FIG. 21C), and when the roller 41 reaches the pressing end position, as shown in FIG. In a horizontal position. The air between the panel P1 and the panel P2 is pushed out from the end portion E2 side by the pressing and movement of the roller 41, so that it is easy to escape, and mixing of bubbles can be reduced.

  When preventing bubbles from being mixed by the method of FIGS. 21A to 21D, depending on the strength and flexibility of the panel P1, immediately after the roller 41 starts pressing, the end E2 side of the panel P1 becomes the panel P2. There may be cases where they touch each other. In this case, air becomes difficult to be pushed out. Therefore, the portion of the panel P1 before being pressed by the roller 41 may be restricted from contacting the panel P2. 22A to 22E are diagrams showing an example thereof.

  In the example of the figure, holding mechanisms 200a and 200b instead of the holding mechanisms 20a and 20b are employed, and the above-described restriction is provided on the holding mechanisms 200a and 200b.

  Referring to FIG. 22A, the holding mechanism 200a includes a holding portion 201a, a regulating portion 202a, a support portion 203a, and an elevating mechanism 204a. Although not shown, for example, the elevating mechanism 204a can be moved in the Y direction with the same configuration as the support member 24 and the moving mechanism 26 described above. Therefore, the holding portion 201a and the restricting portion 202a are movable in the Y direction. It is said that.

  The holding mechanism 200b includes a holding unit 201b, a regulating unit 202b, a support unit 203b, and an elevating mechanism 204b. Although not shown, the elevating mechanism 204b is also movable in the Y direction with the same configuration as the support member 24 and the moving mechanism 26 described above, and therefore the holding unit 201b and the regulating unit 202b are movable in the Y direction. It is said that.

  The holding parts 201a and 201b are claw-like members arranged so as to contact the lower surface of the peripheral edge of the panel P1. The restricting portions 202a and 202b are claw-like members that are disposed apart from the holding portion 201 in the Z direction and restrict the panel P1 on the holding portions 201a and 201b from moving upward. The support parts 203a and 203b are members that support the holding parts 201a and 201b and the regulation parts 202a and 202b. The elevating mechanisms 204a and 204b include a mechanism for elevating and lowering the support portions 203a and 203b.

  As shown in FIG. 22A, the holding portions 201a and 201b are retracted to a position higher than the panel P1 before holding the panel P1. When the panel P1 is held, as shown in FIG. 22B, the holding parts 201a and 201b and the restricting parts 202a and 202b are lowered by the elevating mechanisms 204a and 204b, and the holding parts 201a and 201b and the restricting part 202a are lowered. , 202b, the elevating mechanisms 204a, 204b are moved in the Y direction so that the panel P1 is inserted between them.

  Subsequently, the holding portions 201a and 201b and the regulating portions 202a and 202b are raised by the lifting mechanisms 204a and 204b, and the panel P1 is held by the holding portions 201a and 201b. At this time, as shown in FIG. 22C, by raising the end E1 side to a position higher than the end E2 side, the posture of the panel P1 becomes the same as that in FIG.

  Next, as shown in FIG. 22D, pressing by the roller 41 is started. When the end E1 side is pressed by the roller 41, the end E2 side may also come into contact with the panel P2. However, the restricting portion 202 comes into contact with the end E2, and the end E2 comes close to the panel P2. To regulate that. Thereafter, as in the example of FIGS. 21A to 21D, the holding portions 201a and 201b on the end E2 side are raised in accordance with the movement of the roller 41 (FIG. 22E), and the roller 41 is pressed. When the end position is reached, the panel P1 is set to the horizontal posture.

  Thus, the portion of the panel P1 before being pressed by the roller 41 can be prevented from sticking to the panel P2. As a result, the air between the panel P1 and the panel P2 is easily pushed out from the end portion E2 side by the pressing and movement of the roller 41, and air bubbles can be more reliably reduced.

  In the present embodiment, the restricting portion 202 is also provided in the holding mechanism 200 on the end E1 side, but this may be omitted.

In the case of the present embodiment, the panel P1 is positioned by the upstream adjustment units 14 and 15 before application of the adhesive RG, and the panel P1 is positioned by the downstream adjustment units 14 and 15 even after application. Do. The position detection unit 7 detects the position of the panel P1 and controls the transport amount of the panel P1 so that the bonding position with the panel P2 matches.

  The coating unit 1 is a unit that applies a liquid photocurable resin as an adhesive RG to the surface of the panel P1, and includes a coating head 10 and a moving mechanism 11.

  The coating head 10 is disposed above the air floating table 121 and includes a nozzle 101 disposed so as to face the upper surface of the air floating table 121. The nozzle 101 is capable of discharging a photocurable resin that is liquid and has optical transparency.

  The nozzle 101 is a slit-like nozzle extending in the X direction, and the photocurable resin is continuously discharged downward in a curtain shape extending in the X direction. A liquid film of the photocurable resin can be formed on the surface of the panel P1 by discharging the photocurable resin while the panel P1 is conveyed by the conveyance mechanism 12.

  The moving mechanisms 11 are provided at both ends of the coating head 10 in the X direction, and support the coating head 10 in a horizontal posture. Each moving mechanism 11 includes a driving mechanism (not shown) and is controlled in synchronization with each other to move the coating head 10 in the Z direction.

The curing accelerating device UV1 extends in the X direction, and both end portions thereof are supported by the support columns CL, and are disposed horizontally above the upper surface of the air floating table 121.

  The curing accelerator UV1 includes a light source LTS that extends in the X direction. The light source LTS emits ultraviolet rays. When the laminated body LB moves below the curing accelerating device UV1, by performing a process of irradiating the laminated body LB with ultraviolet light by the light source LTS, curing of the photocurable resin is promoted, and the panel P1 and the panel P2 Adhesion can be made strong.

<Fourth embodiment>
You may provide the structure which accelerates | stimulates hardening of the photocurable resin of the panel P1. FIG. 24 is a plan view of the manufacturing apparatus C of this embodiment. The manufacturing apparatus C is obtained by adding a curing accelerating device UV2 and a shutter device 9 to the manufacturing apparatus B, and the other configuration is the same as that of the manufacturing apparatus B. Note that a configuration in which the curing accelerating device UV1 is not provided in the manufacturing apparatus C can also be employed.

  The curing accelerating device UV2 is disposed downstream of the coating head 10 in the Y direction and upstream of the position detection unit 7, the holding unit 2, and the like. That is, it is located upstream from the bonding position of the panel P1 and the panel P2.

  The configuration of the curing accelerator UV2 is the same as that of the curing accelerator UV1. That is, the curing accelerating device UV2 extends in the X direction, and both ends thereof are supported by the support columns CL and are horizontally disposed above the upper surface of the air floating table 121. The curing accelerating device UV2 includes a light source LTS extending in the X direction. The light source LTS emits ultraviolet rays. When the panel P1 moves below the curing accelerating device UV2, the photocurable resin can be semi-cured by executing a process of irradiating the panel P1 with ultraviolet rays by the light source LTS. Thereby, when the panel P1 and the panel P2 are bonded together, it is possible to prevent bubbles from being mixed and to prevent misalignment between the two, thereby facilitating the handling of the stacked body LB.

The shutter device 9 is disposed between the coating head 10 and the curing accelerating device UV2. The shutter device 9 extends in the X direction, and both end portions thereof are supported by the support columns 92 and are disposed horizontally above the upper surface of the air levitation table 121. The shutter device 9 includes a movable shutter 91 that can shield light between the coating head 10 and the curing accelerating device UV2 .

  When the panel P1 passes below the shutter device 9, the shutter device 9 moves down the shutter 91 to shield between the coating head 10 and the curing accelerating device UV2. Thereafter, the curing accelerating device UV2 is driven and irradiated with ultraviolet rays. Due to the presence of the shutter 91, the coating head 10 is shielded from ultraviolet rays, and the photocurable resin adhering to the nozzle 101 can be prevented from solidifying. When the panel P1 passes through the curing accelerator UV2 and the driving of the light source 91 is stopped, the shutter 91 is raised.
