Description

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

  Examples of the FPD include a liquid crystal display, an organic EL (Electro-Luminescence) display, and a plasma display. A mounting member such as COF (Chip on Film) or FPC (Flexible Printed Circuit) is connected to the peripheral edge of the display substrate in the FPD by TAB (Tape Automated Bonding). The mounting members to which these TAB connections are made are collectively referred to as TAB. This TAB is hereinafter referred to as a mounting member.

  A peripheral substrate such as a PCB (Printed Circuit Board) is mounted around the display substrate. As a result, the FPD module is assembled.

  The FPD module assembling apparatus is configured to assemble a FPD module by sequentially performing a plurality of processing work steps, mounting TAB, PCB, and the like on the periphery and the periphery of the display substrate of the FPD, respectively.

  As an example of the processing operation process in the FPD module assembling apparatus, (1) a terminal cleaning process for cleaning the TAB attaching part at the end of the display substrate, and (2) an anisotropic conductive film (ACF: Anisotropic Conductive Film). Further, there are (3) a temporary press-bonding process in which the TAB is positioned and temporarily press-bonded at the position where the ACF is attached to the display substrate, and (4) a main press-bonding process in which the mounted TAB is heat-pressed and fixed by the ACF. . Further, (5) there is a PCB process in which a PCB substrate on which ACF is previously bonded is attached to the surface of TAB opposite to the display substrate side.

  In each of the above work steps, in order to perform the work accurately, the side part of the display substrate (hereinafter referred to as “working side part”) on which the work is performed is supported so as not to move during the work. This support is performed by a suction table constituting the FPD module assembling apparatus (see Patent Documents 1 and 2).

  A conventional suction table has a suction surface in which a plurality of suction holes are formed over the entire surface. The suction table supports the display substrate disposed on the suction surface by vacuum suction during operation.

  By the way, there are various types of display substrates, and the size of the display surface varies. In order to be able to support all types of display substrates, the suction table is configured such that the suction surface is larger than the display surface of the display substrate of the largest size. The suction table changes the suction area of the suction surface (changes the suction holes for vacuum suction) according to the size of the display surface of the display substrate arranged on the suction surface. The change of the suction area (change of the suction hole for vacuum suction) is performed by opening and closing the suction hole formed on the suction surface with an electromagnetic valve (suction area switching valve).

Japanese Patent Application Laid-Open No. 2001-228452 JP 2002-261495 A

  However, since there are various types of display substrates as described above, in order to hold these display substrates securely, it is necessary to set the suction areas in detail, and the number of suction areas that have been set is switched. A valve must be provided. For this reason, there has been a problem that the manufacturing cost of the FPD module assembling apparatus is increased with an increase in the number of suction area switching valves.

  An object of the present invention is to provide an FPD module assembling apparatus that can securely hold display substrates of various sizes and can reduce the number of suction area switching valves in consideration of the above problems. There is to do.

  In order to solve the above problems and achieve the object of the present invention, an FPD module assembling apparatus of the present invention has a suction surface on which a plurality of suction holes are formed, and a display substrate placed on the suction surface. A display substrate holding mechanism for suction is provided.

  The display substrate holding mechanism includes a vacuum generator for sucking air from a plurality of suction holes, a first suction hole group formed in a first suction region of the suction surface among the plurality of suction holes, and vacuum generation. A first pipe for connecting the gas generator, and a first adsorption region switching valve that is provided in the first pipe and that collectively controls the flow of air from the vacuum generator to the first adsorption hole group by opening and closing. .

  In addition, the display substrate holding mechanism includes a second piping connecting a second suction hole group formed in a second suction region other than the first suction region of the suction surface and a vacuum generator among the plurality of suction holes. And a second adsorption region switching valve that is provided in the second pipe and collectively controls the flow of air from the vacuum generator to the second adsorption hole group by opening and closing.

  Further, the display substrate holding mechanism is a valve with an automatic switching function provided between the boundary suction hole located closest to the second suction region among the suction holes constituting the first suction hole group and the first pipe. Is provided.

  And this valve with an automatic switching function makes the air flowing between the boundary suction hole and the first pipe communicate when the boundary suction hole is completely blocked by the display substrate during suction by the vacuum generator, When the boundary adsorption hole is not completely blocked by the display substrate, the air flowing between the boundary adsorption hole and the first pipe is blocked.

  According to the FPD module assembling apparatus having the above configuration, in a state where a display substrate of a predetermined size is disposed on the suction surface (hereinafter referred to as “arrangement state”), there is a possibility that the display substrate partially blocks the display substrate. A valve with an automatic switching function was placed directly under the boundary adsorption hole. Thereby, when it is in the arrangement state, it is possible to automatically stop the suction at the boundary suction hole partially blocked by the display substrate. As a result, there is no need to provide an electromagnetic valve for controlling ON / OFF of suction at the boundary suction hole that is partially blocked as in the prior art. Therefore, the number of solenoid valves to be provided can be suppressed to the minimum necessary, and the cost can be reduced.

  Further, since the suction can be performed only by the suction holes closed by the display substrate regardless of the size (type) of the display substrate, the display substrate can be reliably held.

First, when the type of the display substrate 1A is input via an operation unit (not shown), the widths of the suction table 710 and the suction beam 800 in the X-axis direction are determined based on the types.

  Subsequently, the first moving suction board 712 and the second moving suction board 713 of the suction table 710 move by a predetermined amount in the direction along the X axis so that the width of the suction table 710 in the X-axis direction becomes the determined width. To do. Then, the first moving suction bar 802 and the first moved suction bar 804, the second moving suction bar 803 and the second of the suction beam 800 are set so that the width of the suction beam 800 in the X-axis direction becomes the determined width. The moved suction bar 805 moves a predetermined amount in the direction along the X axis. The widths in the X-axis direction of the suction table 710 and the suction beam 800 in this state are referred to as a suction table reference width and a suction beam reference width, respectively.

  Subsequently, among the first to fourth adsorption region switching valves 910 to 913 (see FIG. 5), only the third and fourth adsorption region switching valves 912 and 913 are opened. Then, air is sucked from the third and fourth pipes 903 and 904 by the vacuum suction device 914.

  Subsequently, as shown in FIG. 6A, the display substrate 1A is placed on the suction surface 710A so as to completely close all the suction holes formed on the suction surface 710A of the suction table 710 disposed at the receiving position. . At this time, since the suction holes 716c, 717c, and 718c immediately above the valves 907, 908, and 909 with automatic switching function are completely blocked by the display substrate 1A, the valves 907, 908, and 909 with automatic switching function are opened. . As a result, the display substrate 1A is sucked by all the suction holes formed on the suction surface 710A of the suction table 710.

  Subsequently, the suction table 710 is moved on the Y-axis guide 760 from one side of the Y-axis direction to the other side by the Y-axis slider 750 (see FIG. 3), and the display substrate 1A sucked on the suction table 710 is As shown in FIG. 6B, the suction beam 800 is disposed above.

  Subsequently, the first and second adsorption region switching valves 910 and 911 (see FIG. 5) are opened. Then, air is sucked from the first and second pipes 901 and 902 by the vacuum suction device 914. At this time, since the suction holes 809c and 810c immediately above the valves 905 and 906 with the automatic switching function are completely closed by the display substrate 1A, the valves 905 and 906 with the automatic switching function are opened. Thereby, the display substrate 1A has its working side (both short side and one long side) adsorbed by all the suction holes formed on the suction surface (suction surfaces 801A to 805A) of the suction beam 800, It is held at the work position of the work unit.

  After the above processing is completed, the third and fourth adsorption region switching valves 912 and 913 (see FIG. 5) are closed. Then, the suction of air from the third and fourth pipes 903 and 904 by the vacuum suction device 914 is blocked, and the suction of the display substrate 1A by the suction table 710 is released. Then, as shown in FIG. 6C, the suction table 710 is moved on the Y-axis guide 760 from the other side in the Y-axis direction to one side by the Y-axis slider 750, and returns to the receiving position.

  Next, an operation example when the display substrate 1 held by the display substrate holding device 600 is a medium size (M size) display substrate 1B will be described with reference to FIGS. In FIG. 7, as in FIG. 6, a part of the reference numerals shown in FIG. 4 is omitted for easy viewing of the drawing.

FIG. 7 is a top view of a display substrate holding device 600 according to an embodiment of the present invention.
First, when the type of the display substrate 1B is input via an operation unit (not shown), the widths of the suction table 710 and the suction beam 800 in the X-axis direction are determined based on the types. Specifically, the difference between the length of the long side portion of the display substrate 1A and the length of the long side portion of the display substrate 1B (hereinafter referred to as “LM difference”) is larger than the suction table reference width and the suction beam reference width. The widths of the suction table 710 and the suction beam 800 in the X-axis direction are determined so as to be shorter.

  Then, from the state shown in FIG. 6A, the distance corresponding to ½ of the LM difference in the direction in which the first moving suction board 712 and the second moving suction board 713 of the suction table 710 approach the fixed suction board 711, respectively.

  Subsequently, as shown in FIG. 7A, the suction so as to completely block all the suction holes formed in the third area 853 (see FIG. 4) of the suction surface 710A of the suction table 710 arranged at the receiving position. The display substrate 1B is placed on the surface 710A. At this time, the suction holes 716c to 718c immediately above the valves 907, 908, 909 with automatic switching function are completely blocked by the display substrate 1B, and the valves 907, 908, 909 with automatic switching function are opened. As a result, the display substrate 1B is sucked by all the suction holes formed in the third area 853 (see FIG. 4) of the suction surface 710A of the suction table 710.

  Subsequently, the suction table 710 is moved on the Y-axis guide 760 from one side to the other side in the Y-axis direction by the Y-axis slider 750 (see FIG. 3), and the display substrate 1B sucked on the suction table 710 is As shown in FIG. 7B, the suction beam 800 is disposed above. Then, the suction table 710 is lowered by the elevating unit 730, and the display substrate 1B sucked by the suction table 710 is all formed in the first area 851 (see FIG. 4) of the suction surface (suction surfaces 801A to 805A). It is placed on the suction surface (suction surfaces 801A to 805A) so as to completely block the suction holes.

  Subsequently, the first adsorption region switching valve 910 (see FIG. 5) is opened. Then, air is sucked from the first pipe 901 by the vacuum suction device 914. At this time, since the suction holes 809c and 810c immediately above the valves 905 and 906 with automatic switching function are completely blocked by the display substrate 1B, the valves 905 and 906 with automatic switching function are opened. As a result, the work side (both short side and one long side) of the display substrate 1B is sucked by all the suction holes formed in the first area 851 of the suction beam 800, and the work position of the work unit Held in.

  After the above processing is completed, the third adsorption region switching valve 912 (see FIG. 5) is closed. Then, the suction of air from the third pipe 903 by the vacuum suction device 914 is blocked, and the suction of the display substrate 1B by the suction table 710 is released. Then, as shown in FIG. 7C, the suction table 710 is moved on the Y-axis guide 760 from the other side in the Y-axis direction to one side by the Y-axis slider 750 (see FIG. 3), and returns to the receiving position.

Note that, in FIG. 8, as in FIG. 6, in order to make the drawing easier to see, some of the reference numerals shown in FIG. 4 are omitted.

FIG. 8 is a top view of a display substrate holding device 600 according to an embodiment of the present invention.
First, when the type of the display substrate 1C is input via an operation unit (not shown), the widths of the suction table 710 and the suction beam 800 in the X-axis direction are determined based on the types. Specifically, the suction table is set such that the difference between the length of the long side portion of the display substrate 1A and the length of the long side portion of the display substrate 1C (hereinafter referred to as “LS difference”) is shorter than the reference width. 710 and the width of the adsorption beam 800 in the X-axis direction are determined.

  Subsequently, from the state shown in FIG. 6A, the first moving suction board 712 and the second moving suction board 713 of the suction table 710 are each equivalent to ½ of the LS difference in a direction approaching the fixed suction board 711. Move along the X axis by a distance. At this time, the first moving suction bar 802 and the first moved suction bar 804, the second moving suction bar 803, and the second moved suction bar 805 of the suction beam 800 are moved closer to the fixed suction bar 801, respectively. It moves along the X axis by a distance corresponding to 1/2 of the LS difference.

  Subsequently, among the first to fourth adsorption region switching valves 910 to 913 (see FIG. 5), only the third adsorption region switching valve 912 is opened. Then, air is sucked from the third pipe 903 by the vacuum suction device 914.

  Subsequently, the display substrate 1C is placed on the suction surface 710A of the suction table 710 disposed at the receiving position. At this time, as shown in FIG. 8A, the suction holes 716a, 716b, 717a, 717b, 718a, 718b of the third area 853 (see FIG. 4) are completely closed by the display substrate 1C, but the suction holes 716c, 717c , 718c is not completely blocked. Therefore, the automatic switching function-equipped valves 907 to 909 arranged immediately below the suction holes 716c, 717c, and 718c are in a closed state. As a result, the display substrate 1C is sucked only by the suction holes 716a, 716b, 717a, 717b, 718a, and 718b completely closed by the display substrate 1C. Therefore, the display substrate 1C can be reliably held.

  Subsequently, the suction table 710 is moved on the Y-axis guide 760 from one side to the other side in the Y-axis direction by the Y-axis slider 750 (see FIG. 3), and the display substrate 1C sucked on the suction table 710 is As shown in FIG. 8B, the suction beam 800 is disposed above. The suction table 710 is lowered by the elevating unit 730, and the display substrate 1C sucked by the suction table 710 is placed on the suction surface (suction surfaces 801A to 805A) of the suction beam 800. At this time, the suction holes 806a to 806d, 807a to 807c, 808a to 808c, 809a, 809b, 810a, and 810b in the first area 851 are completely blocked by the display substrate 1C, but the suction holes 809c and 810c are completely closed. I can't block it.

  Subsequently, the first adsorption region switching valve 910 (see FIG. 5) is opened. Then, air is sucked from the first pipe 901 by the vacuum suction device 914. Here, since the suction holes 809c and 810c immediately above the valves 905 and 906 with automatic switching function are not completely closed by the display substrate 1C (see FIG. 8B), the valves 905 and 906 with automatic switching function are closed. Become. As a result, the display substrate 1C is adsorbed only by the suction holes 806a to 806d, 807a to 807c, 808a to 808c, 809a, 809b, 810a, and 810b completely closed by the display substrate 1C. As a result, it is possible to reliably hold the working side portions (both short side portions and one long side portion) of the display substrate 1C.

  After the above processing is completed, the third adsorption region switching valve 912 (see FIG. 5) is closed. Then, the suction of air from the third pipe 903 by the vacuum suction device 914 is blocked, and the suction of the display substrate 1C by the suction table 710 is released. Then, as shown in FIG. 8C, the suction table 710 is moved on the Y-axis guide 760 from the other side in the Y-axis direction to one side by the Y-axis slider 750 (see FIG. 3), and returns to the receiving position.

  As described above, in one embodiment of the present invention, for example, the display substrate 1C (S size display substrate 1) is disposed on the suction surface of the suction table and the suction surface of the suction beam (hereinafter referred to as “arrangement state”). In other words, a valve with an automatic switching function is disposed immediately below the suction hole partially blocked by the display substrate 1C. Thereby, when it is in the arrangement state, it is possible to automatically stop the suction in the suction hole partially blocked by the display substrate 1C. As a result, there is no need to provide an electromagnetic valve for controlling ON / OFF of suction in the suction hole partially blocked by the display substrate 1C as in the conventional case. Therefore, the number of solenoid valves to be provided can be suppressed to the minimum necessary, and the cost can be reduced.

  In one embodiment of the present invention, the display substrate 1 is sucked only by the suction holes completely closed by the display substrate 1 regardless of the size of the display substrate 1. Thereby, the display substrate can be reliably held.

  In one embodiment of the present invention, the width of the suction beam and the suction table in the X-axis direction can be changed according to the type of the display substrate 1. Thereby, it is not necessary to divide the suction surface of the suction beam and the suction table into, for example, four suction areas (first to fourth areas) or more. Therefore, it is possible to further reduce the number of solenoid valves that need to be provided for each suction area, and to further reduce the cost.

An operation example when the display substrate 1 held by the display substrate holding device is the display substrate 1A having the largest size (L size) will be described with reference to FIGS. In FIG. 11, in order to make the drawing easier to see, some of the reference numerals shown in FIG. 9 are omitted.

FIG. 11 is a top view of a display substrate holding apparatus according to another embodiment of the present invention.
First, when the type of the display substrate 1A is input via an operation unit (not shown), the arrangement position of the movable support bar 940 is determined along with the widths of the suction table 920 in the X-axis direction and the Y-axis direction based on the type. Is done.

  Then, the first moving suction board 922 of the suction table 920 moves in the direction along the X axis and the second moving suction board 923 moves in the direction along the Y axis so as to have the determined width. The third moving suction board moves in the direction along the X axis and moves in the direction along the Y axis. Then, the movement support bar 940 moves along the X-axis direction so as to be arranged at the determined position. In this state, the respective widths of the suction table 920 in the X-axis direction and the Y-axis direction are referred to as an X-axis direction reference width and a Y-axis direction reference width, and the arrangement position of the moving support bar 940 is referred to as a reference arrangement position.

  Subsequently, among the first to third adsorption region switching valves 970 to 972 (see FIG. 10), only the third adsorption region switching valve 972 is opened. Then, air is sucked from the third pipe 963 by the vacuum suction device 914.

  Subsequently, as shown in FIG. 11A, the suction surfaces (suction surfaces 921A to 924A) are closed so as to block all the suction holes formed in the suction surfaces (suction surfaces 921A to 924A) of the suction table 920 arranged at the receiving position. ) Is placed on the display substrate 1A. At this time, the suction holes 927c, 927d, 928c, and 928d immediately above the valves 966 to 969 with the automatic switching function are closed with the display substrate 1A. As a result, the valves 966 to 969 with an automatic switching function are opened, and the display substrate 1A is sucked by all the suction holes formed in the suction surfaces 921A to 924A of the suction table 920.

  Subsequently, the suction table 920 is moved on the Y-axis guide 760 by the Y-axis slider 750 (see FIG. 3) from one side to the other side in the Y-axis direction, and the display substrate 1A sucked on the suction table 920 is As shown in FIG. 11B, the suction beam 930 is disposed vertically above.

It is mounted on the mounting surface 940 </ b> A of the moving support bar 940.

  Subsequently, the first and second adsorption region switching valves 970 and 971 (see FIG. 10) are opened. Then, air is sucked from the first and second pipes 961 and 962 by the vacuum suction device 914. At this time, since the suction holes 933f and 934c just above the automatic switching function-equipped valves 964 and 965 are blocked by the display substrate 1A, the automatic switching function-equipped valves 964 and 965 are opened. As a result, the display substrate 1A has its working side (the short side on one side of the X axis and the other side of the Y axis) by all the suction holes formed on the suction surfaces (suction surfaces 931A, 932A) of the suction beam 930. The long side) is adsorbed and held at the work position of the work unit.

  After the above processing is completed, the third adsorption region switching valve 972 (see FIG. 10) is closed. Then, the suction of air from the third pipe 963 by the vacuum suction device 914 is blocked, and the suction of the display substrate 1A by the suction table 920 is released. Then, as shown in FIG. 11C, the suction table 920 is moved on the Y-axis guide 760 from the other side in the Y-axis direction to one side by the Y-axis slider 750 (see FIG. 3), and returns to the receiving position.

  Specifically, the difference between the length of the long side portion of the display substrate 1A and the length of the long side portion of the display substrate 1B (hereinafter referred to as “LM long side portion difference”) is shorter than the reference width in the X-axis direction. Thus, the width of the suction table 920 in the X-axis direction is determined. Then, the difference between the length of the short side portion of the display substrate 1A and the length of the short side portion of the display substrate 1B (hereinafter referred to as “LM short side portion difference”) is shorter than the reference width in the Y-axis direction. The width of the suction table 920 in the Y-axis direction is determined.

  Subsequently, the first to third movable suction boards 922 to 924 of the suction table 920 move from the state illustrated in FIG. 11A so as to have the determined width. That is, the first moving suction board 922 moves along the distance X axis corresponding to the LM long side difference in a direction approaching the fixed suction board 921. The second moving suction board 923 moves along the distance Y axis corresponding to the LM short side difference in a direction approaching the fixed suction board 921. The third moving suction board 924 moves along the distance X-axis corresponding to the LM long side difference in the direction approaching the fixed suction board 921, and the LM short in the direction approaching the fixed suction board 921. It moves along the distance Y axis corresponding to the side difference. At this time, the moving support bar 940 moves along the X axis by a distance corresponding to the LM long side difference in the direction approaching the adsorption beam 930.

  Subsequently, among the first to third adsorption region switching valves 970 to 972 (see FIG. 10), only the third adsorption region switching valve 972 is opened. Then, air is sucked from the third pipe 963 by the vacuum suction device 914.

  Subsequently, as shown in FIG. 12A, the suction surfaces (suction surfaces 921A to 924A) are closed so as to block all the suction holes formed in the suction surfaces (suction surfaces 921A to 924A) of the suction table 920 arranged at the receiving position. ) Is placed on the display substrate 1B. At this time, the suction holes 927c, 927d, 928c, 928d immediately above the valves 966 to 969 with an automatic switching function are closed by the display substrate 1B. As a result, the valves 966 to 969 with an automatic switching function are opened, and the display substrate 1B is sucked by all the suction holes formed on the suction surfaces 921A to 924A of the suction table 920.

  Subsequently, the suction table 920 is moved on the Y-axis guide 760 from one side to the other side in the Y-axis direction by the Y-axis slider 750 (see FIG. 3), and the display substrate 1B sucked on the suction table 920 is As shown in FIG. 12B, the suction beam 930 is disposed vertically above. Then, the suction table 920 is lowered by the elevating unit 730. Then, the display substrate 1B sucked on the suction table 920 moves and moves to the suction surfaces (suction surfaces 931A, 932A) so as to close the suction holes 933a to 933f and 934a to 934c formed in the first area 951 of the suction beam 930. It is mounted on the mounting surface 940A of the support bar 940.

  Subsequently, the first adsorption region switching valve 970 (see FIG. 10) is opened. Then, air is sucked from the first pipe 961 by the vacuum suction device 914. At this time, since the suction holes 933f and 934c immediately above the valves 964 and 965 with an automatic switching function are closed by the display substrate 1B, the valves 964 and 965 with an automatic switching function are opened. As a result, the display substrate 1B has its working side (the short side on one side of the X axis and the other side of the Y axis) by the suction holes 933a to 933f and 934a to 934c formed in the first area 951 of the suction beam 930. The long side) is adsorbed and held at the work position of the work unit.

  After the above processing is completed, the third adsorption region switching valve 972 (see FIG. 10) is closed. Then, the suction of air from the third pipe 963 by the vacuum suction device 914 is blocked, and the suction of the display substrate 1B by the suction table 920 is released. Then, as shown in FIG. 12C, the suction table 920 is moved on the Y-axis guide 760 from the other side of the Y-axis toward the one side by the Y-axis slider 750 (see FIG. 3), and returns to the receiving position.

  Next, an operation example when the display substrate 1 held by the display substrate holding device is the display substrate 1C having the smallest size (S size) will be described with reference to FIGS. In FIG. 13, in order to make the drawing easier to see, some of the reference numerals shown in FIG. 9 are omitted. Further, the widths of the suction table 920 in the X-axis direction and the Y-axis direction are not smaller than the width shown in FIG.

FIG. 13 is a top view of a display substrate holding apparatus according to another embodiment of the present invention.
First, when the type of the display substrate 1C is input via an operation unit (not shown), the arrangement position of the movement support bar 940 is determined along with the widths of the suction table 920 in the X-axis direction and the Y-axis direction based on the type. Is done.

  Specifically, the difference between the length of the long side portion of the display substrate 1A and the length of the long side portion of the display substrate 1C (hereinafter referred to as “LS long side portion difference”) is shorter than the reference width in the X-axis direction. Thus, the width of the suction table 920 in the X-axis direction is determined. The difference between the length of the short side portion of the display substrate 1A and the length of the short side portion of the display substrate 1C (hereinafter referred to as “LS short side portion difference”) is shorter than the reference width in the Y-axis direction. The width of the suction table 920 in the Y-axis direction is determined.

  Subsequently, from the state shown in FIG. 11A, the first to third movable suction boards 922 to 924 of the suction table 920 move so as to have the determined width. However, the widths of the suction table 920 in the X-axis direction and the Y-axis direction are not smaller than the width shown in FIG. Therefore, the first moving suction board 922 moves in the direction approaching the fixed suction board 921 along the distance X axis corresponding to the LM long side difference, and the movement is stopped. The second moving suction board 923 moves in the direction approaching the fixed suction board 921 along the distance Y axis corresponding to the LM short side difference, and the movement is stopped. The third moving suction board 924 moves along the distance X-axis corresponding to the LM long side difference in the direction approaching the fixed suction board 921, and the LM short in the direction approaching the fixed suction board 921. The movement is stopped along the distance Y-axis corresponding to the side difference. At this time, the moving support bar 940 moves along the X axis by a distance corresponding to the LS long side difference in the direction approaching the suction beam 930.

  Subsequently, among the first to third adsorption region switching valves 970 to 972 (see FIG. 10), only the third adsorption region switching valve 972 is opened. Then, air is sucked from the third pipe 963 by the vacuum suction device 914.

  Subsequently, as illustrated in FIG. 13A, the display substrate 1C is placed on the suction surfaces (suction surfaces 921A to 924A) of the suction table 920 arranged at the receiving position. At this time, the suction holes 925a to 925d, 926a to 926d, 927a, 927b, 928a, and 928b in the third area 953 (see FIG. 9) are completely blocked by the display substrate 1C, but the suction holes 927c, 927d, 928c, 928d is not completely blocked. Therefore, the automatic switching function-equipped valves 966 to 969 arranged immediately below the suction holes 927c, 927d, 928c, and 928d are closed. As a result, the display substrate 1C is adsorbed only by the adsorption holes 925a to 925d, 926a to 926d, 927a, 927b, 928a, and 928b that are completely blocked by the display substrate 1C. Therefore, the display substrate 1C can be reliably held.

  Subsequently, the suction table 920 is moved on the Y-axis guide 760 from one side to the other side in the Y-axis direction by the Y-axis slider 750 (see FIG. 3), and the display substrate 1C sucked on the suction table 920 is As shown in FIG. 13B, the suction beam 930 is disposed vertically above. Then, the suction table 920 is lowered by the elevating unit 730. Then, the display substrate 1 </ b> C sucked by the suction table 920 is placed on the suction surface (suction surfaces 931 </ b> A and 932 </ b> A) of the suction beam 930 and the placement surface 940 </ b> A of the moving support bar 940. At this time, the suction holes 933a to 933e, 934a, and 934b in the first area 951 are completely closed by the display substrate 1C, but the suction holes 933f and 934c are not completely closed.

  Subsequently, the first adsorption region switching valve 970 (see FIG. 10) is opened. Then, air is sucked from the first pipe 961 by the vacuum suction device 914. Here, since the suction holes 933f and 934c immediately above the valves 964 and 965 with automatic switching function are not completely closed by the display substrate 1C (see FIG. 13B), the valves 964 and 965 with automatic switching function are closed. Become. Thereby, the display substrate 1C is adsorbed only by the adsorption holes 933a to 933e, 934a, and 934b completely closed by the display substrate 1C. As a result, the display substrate 1C is placed at the work position of the work unit in a state where the work side (the short side and one long side) of the display substrate 1C is held.

  After the above processing is completed, the third adsorption region switching valve 972 (see FIG. 10) is closed. Then, the suction of air from the third pipe 963 by the vacuum suction device 914 is blocked, and the suction of the display substrate 1C by the suction table 920 is released. Then, as shown in FIG. 13C, the suction table 920 is moved on the Y-axis guide 760 from the other side in the Y-axis direction to one side by the Y-axis slider 750 (see FIG. 3), and returns to the receiving position.

  As described above, in another embodiment of the present invention, as in the embodiment, for example, the display substrate 1C (S size display substrate 1) is arranged on the suction surface of the suction table and the suction surface of the suction beam. In the state (hereinafter, referred to as “arrangement state”), the valve with an automatic switching function is disposed immediately below the suction hole partially blocked by the display substrate 1C. Thereby, when it is in the arrangement state, it is possible to automatically stop the suction in the suction hole partially blocked by the display substrate 1C. As a result, there is no need to provide an electromagnetic valve for controlling ON / OFF of suction in the suction hole partially blocked by the display substrate 1C as in the conventional case. Therefore, the number of solenoid valves to be provided can be suppressed to the minimum necessary, and the cost can be reduced.

  Further, in another embodiment of the present invention, like the one embodiment, the display substrate 1 is sucked only by the suction holes completely closed by the display substrate 1 regardless of the size of the display substrate 1. did. Thereby, the display substrate can be reliably held.

  In another embodiment of the present invention, the widths of the suction table in the X-axis direction and the Y-axis direction can be changed according to the type of the display substrate 1. Thereby, it is not necessary to divide the suction surface of the suction beam and the suction table into, for example, three suction areas (first to third areas) or more. Therefore, it is possible to further reduce the number of solenoid valves that need to be provided for each suction area, and to further reduce the cost.
