When the second panel fixing device 62 has a structure that fixes the second panel P2 using vacuum pressure (suction input), the vacuum pressure of the second panel fixing device 62 is fixed to the second panel. It should be above the vacuum pressure provided to the vacuum chamber 28 of the housing 27 in which the device 62 is housed.

The inversion frame 74 is installed in the vacuum chamber 28 so that its upper and lower surfaces can be reversed. Lever 75 is coupled to both ends of the inversion frame 74, one lever 75 is coupled to the rotary shaft 78 of the inverter 77, the other lever 75 to the housing 27 The support shaft 79 coupled to the is coupled. The rotary shaft 78 and the support shaft 79 are on the same line, and the inverted frame 74 is rotated by 180 degrees with the rotary shaft 78 and the support shaft 79 as the center of rotation so that the upper and lower surfaces thereof can be reversed. have. The reversing device 77 is disposed outside the housing 27 except for a part of the rotation shaft 78 such as a drive unit in which friction occurs during operation. In this way, when most components of the inverting device 77 are disposed outside the housing 27, foreign substances such as powders and lubricants of parts generated due to component wear and the like during the operation of the inverting device 77 enter the vacuum chamber 28. When the first panel P1 and the second panel P2 are attached to each other, a problem of inflow between the first panel P1 and the second panel P2 may be prevented. In addition, repair or replacement of the components of the reversing apparatus 77 becomes easy.

After the inversion frame 74 is inverted, the inversion frame fixing device 80 is installed in the housing 27 to fix the inversion frame 74 in its inverted state. The inversion frame fixing device 80 is a fixing protrusion 81 inserted into the fixing hole 76 provided on the side of the inverting frame 74 and a fixing installed in the housing 27 to advance the fixing protrusion 81. And a projection retraction device 82. The fixing protrusion retractor 82 is installed outside the housing 27, and the fixing protrusion 81 penetrates the housing 27, and an end thereof is positioned in the vacuum chamber 28.

In the figure, it is shown that fixing holes 76 are provided at both ends of the inversion frame 74, and a pair of inversion frame fixing devices 80 fixes the inversion frame 74. The installation number of 80 may be variously changed. In addition to the structure having the fixing protrusion 81 that advances and revolves, the specific configuration of the inversion frame fixing device 80 may be changed to various other structures that can stably hold the inverted inversion frame 74.

1 and 3, the housing sealing apparatus 15 is in close contact with the housing 27 and the sealing cover 84 for opening and closing the doorway 29, and the sealing cover 84 for opening and closing the doorway 29. It may include a sealing cover moving device 85 for moving the sealing cover 84 to be able to. The hermetic cover moving device 85 is coupled to the fixing base 86 which is disposed higher than the panel bonding machine 13 in the panel bonding zone Z4. The hermetic cover 84 is installed on the holder 86 so as to be movable up and down by a guide bar 87 which is slidably coupled to the hermetic cover moving device 85 and the holder 86.

When the sealing cover moving device 85 moves the sealing cover 84 downward, the sealing cover 84 is stably lowered while being supported by the guide bar 87 to seal the entrance 29 of the housing 27. can do. The sealing cover 84 is coupled to the vacuum tube 88 is connected to the vacuum generator 16. By operating the vacuum pressure generator 16 in a state where the sealing cover 84 seals the entrance 29 of the housing 27, forcibly discharging the air inside the vacuum chamber 28 through the vacuum tube 88. The vacuum chamber 28 can be brought to a vacuum state.

In the present invention, the moving structure of the sealed cover moving device 85 or the sealed cover 84 is not limited to that shown and can be variously changed. A packing 30 for sealing between the housing 27 and the sealing cover 84 may be provided in the sealing cover 84. In addition, the vacuum tube 88 connected to the vacuum generator 16 to provide a vacuum pressure to the vacuum chamber 28 may be connected to the housing 27 instead of the sealing cover 84.

In addition, the present invention may be bonded to the panel by using the above-described panel bonding machine alone in addition to the turntable structure as described above. In this case, the vision device, the housing sealing device, and the like, which are necessary for the panel bonding, may be appropriately disposed around the panel bonding machine.

Embodiments of the present invention described above and illustrated in the drawings should not be construed as limiting the technical spirit of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can improve and change the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the protection scope of the present invention as long as it will be apparent to those skilled in the art.
