Thus, the tray 10 on which the panel assembly 20 is loaded is put back into the housing 200 .

In this way, the control device 600 controls the panel assembly 20 while the tray 10 on which the panel assembly 20 is loaded passes sequentially through the preheating chamber 203 , the process chamber 218 , and the buffer chamber 233 . The overall operation of the autoclave apparatus 100 is controlled so that the preheating process, the heat treatment process, and the postheating process are continuously performed. In addition, the control device 600 controls the tray transport device 500 so that the tray 10 discharged from the housing 200 is transferred to the inlet 204 side so that the panel assembly 20 is continuously moved inside the housing 200 . to be put into

As described above, in the autoclave apparatus 100 according to an embodiment of the present invention, the preheating chamber 203 and the process chamber 218 inside the housing 200 are provided with the tray 10 on which the panel assembly 20 is loaded. ) and the buffer chamber 233 , a preheating process, a heat treatment process, and a postheating process may be sequentially performed on the panel assembly 20 . Therefore, it is possible to effectively perform the operation of removing air bubbles and increasing the adhesion to the panel assembly 20 .

In addition, in the autoclave apparatus 100 according to an embodiment of the present invention, after preheating the panel assembly 20 in the preheating chamber 203 , heat treatment is performed by applying a constant temperature and pressure in the process chamber 218 , and the heat-treated panel Since the assembly 20 is discharged after being heated in the buffer chamber 233 , it is possible to prevent the panel assembly 20 from being damaged due to thermal shock in the process of processing the panel assembly 20 , and a high-quality panel assembly 20 ) can be provided.

In addition, in the autoclave apparatus 100 according to an embodiment of the present invention, since the preheating process, the heat treatment process, and the postheating process for the panel assembly 20 are continuously performed, the operation is efficient and the operation time can be shortened. .

In addition, in the autoclave apparatus 100 according to an embodiment of the present invention, if there is a portion that does not reach the preset temperature or pressure in the process chamber 218 in which the panel assembly 20 is heat-treated, the preset temperature or pressure is present. By supplying new high-temperature and high-pressure gas while evacuating the gas from the portion that does not reach the required level, the temperature or pressure in the portion can be quickly increased. Accordingly, the entire process chamber 218 can be maintained at a uniform temperature and pressure, and all panel assemblies 20 injected into the process chamber 218 are heat-treated under uniform conditions to reduce the defect rate, and a plurality of panel assemblies (20) can be batch-processed to shorten the working time.

In addition, the autoclave apparatus 100 according to an embodiment of the present invention automatically transfers the tray 10 that has passed through the buffer chamber 233 to the inlet 204 side, thereby reducing work force and increasing workability. have.

In addition, since the autoclave apparatus 100 according to an embodiment of the present invention can continuously and rapidly perform heat treatment on the panel assembly 20 in connection with a front and rear process apparatus such as a panel attachment apparatus or a panel inspection apparatus, the product can improve productivity.

Although preferred examples of the present invention have been described above, the scope of the present invention is not limited to the forms described and illustrated above.

For example, in the drawing, the housing 200 is divided into a preheating housing 202 , a process housing 217 , and a buffer housing 232 , and a space between the preheating housing 202 and the process housing 217 is removed. It is shown that the first cover 242 covers, and the second cover 243 covers the space between the process housing 217 and the buffer housing 232, but the housing 200 includes the inlet 204 and the preheating chamber ( 203 , a process chamber 218 , a buffer chamber 233 , and an outlet 235 may be modified into various other structures.

In addition, although it is shown in the drawing that one heat treatment gas supply device 247 supplies heated gas to the inside of the process housing 217 , a heat treatment gas supply device that supplies heated gas to the process chamber 218 ( 247) may be plural.

In addition, in the drawing, the inlet door 257, the first intermediate door 270, the second intermediate door 285, and the outlet door 290 move from the lower side to the upper side to open and close the transfer passage of the tray 10. However, the opening and closing structure of these doors may be variously changed.

In addition, the inlet door 257, the first intermediate door 270, the second intermediate door 285, and the outlet door 290 have a structure in which the packing protrudes from the door body by the gas supplied from the gas supply for the door. In addition, the preheat chamber 203 , the process chamber 218 , and the buffer chamber 233 may be modified into various other structures capable of sealing each other.

In addition, although the drawing shows that the tray input device 300 and the tray discharge device 400 are each one, a plurality of them may be disposed, respectively.

In addition, although it is shown in the drawings that each of the preheating chamber tray transfer device 212 and the buffer chamber tray transfer device 240 is one, a plurality of these may also be disposed on the process chamber trolley like the transfer device.
