It can be a tube with. In other words, the second pressing part 6200 has an elongation in the thickness direction (Z-axis direction) compared to the elongation in the width direction (Y-axis direction) and the longitudinal direction (X-axis direction) of the first object S1. It can be a tube with large properties.

At this time, since the second pressing portion 6200 is fixedly installed on the base 6700 and the position of the base 6700 is fixed, the second pressing portion 6200 is expanded, so that the second pressing portion 6 When the fluid is supplied to 6200, the second pressing part 6200 expands in an upward direction so that its thickness is increased.

Then, by raising the first pressing portion 6100, so that the second object (S2) seated on the upper portion of the first pressing portion (6100) in contact with the first object (S1), the first 2 When the pressing portion 6200 is inflated, a pushing force is generated in the first pressing portion 6100 located on the upper portion.

The first to-be-processed object S1 seated on the first pressing part 6100 is pressurized to the second to-be-processed object S2, and the second pressing part 6200 as described above is the first to-be-processed object ( S1) serves to ensure that a sufficient pressing force is applied to the curved portion CA. That is, in the second pressing part 6200, when the first pressing part 6100 presses the second object S2 to the first object, the flat part FA of the first object S1 ) And a uniform pressing force can be applied to the curved portion CA.

More specifically, as illustrated in FIGS. 5 and 7, when the upper chamber 110 is lowered so that the first to-be-processed object S1 and the second to-be-processed object S2 are closer to each other, the first pressure is applied. The center of the Y-axis direction of the second object S2 supported on the upper portion of the portion 6100 and the center of the first object S1 are in contact with each other.

Then, when the base 6700 and the first pressing part 6100 are raised in the direction of the jig 200 using the elevating driving part 6500, the first pressing part 6100 as shown in FIGS. 6 and 8 Is pressed and compressed in the direction of the first object to be treated (S1). Accordingly, the second to-be-processed object S2 on the first pressing part 6100 is pressed in the direction of the first to-be-processed object S1.

However, since the first to-be-processed object S1 has a curved edge, the pressing force transmitted to the curved portion CA is compared to the pressing force transmitted to the flat portion FA by the first pressing portion 6100. small. Accordingly, a uniform pressing force is not applied in the width direction (Y-axis direction) of the first object S1.

This is a factor that causes a poor bonding quality or uneven bonding quality in the curved portion of the first to-be-processed object S1 and the second to-be-processed object S2.

On the other hand, in the present invention, the expandable second pressing portion 6200 is disposed under the first pressing portion 6100 so as to face or face the curved portion CA of the first object S1.

Then, by raising the first pressing portion 6100 in the direction of the jig 200, as shown in FIGS. 6 and 8, pressing and pressing the first pressing portion 6100 in the direction of the first object to be processed (S1) When it is, the second pressing part 6200 is inflated through the expansion controller 6400.

When the first pressing part 6100 is raised so that the first pressing part 6100 and the second to-be-processed object S2 seated thereon are deformed into a shape corresponding to the first to-be-processed object S1. , When the second pressing portion 6200 is expanded, a pressing force is further applied in an edge direction of the first pressing portion 6100. That is, when the second pressing portion 6200 is expanded, the expanding force is transmitted to the first pressing portion 6100, which is transmitted to the curved portion CA of the first object S1. Therefore, in addition to the pressing force due to the increase in the first pressing portion 6100, additional pressure due to the expansion of the second pressing portion 6200 is applied to the curved portion CA of the first object S1. In other words, a double pressure is applied to the curved portion CA of the first to-be-processed object S1 by the rise of the first pressing portion 6100 and the expansion of the second pressing portion 6200. For this reason, it is possible to increase the pressing force transmitted to the curved surface CA of the first to-be-processed object S1, and to apply a uniform pressing force to the first to-be-processed object S1 as compared to the prior art.

Accordingly, in bonding the first to-be-processed object S1 and the second to-be-processed object S2 to each other, the bonding defects and the non-uniform bonding problems of the curved portion CA of the first to-be-processed object S1 are compared with those of the prior art. It can be suppressed or prevented.

9 is a result of measuring the pressing force for each position in the Y-axis direction of the first to-be-processed object when the second to-be-processed object is joined to the first to-be-processed object by using the pressing device according to the first and comparative examples. to be.

The pressing device according to the comparative example is a pressing device having only the first pressing portion 6100. Further, the pressing device 6000 according to the embodiment is positioned to face or face the curved portion CA of the first object S1 under the first pressing portion 6100 and the first pressing portion 6100. It is a pressurizing device having a second pressurizing portion 6200 that can be expanded.

In the X-axis of FIG. 9, '0' is the center position of the width direction (Y-axis direction) of the first object S1, and '39' is the width direction (Y-axis direction) of the first object S1. ).

Referring to FIG. 9, in the case of the comparative example, the pressing force tends to decrease from the center of the Y-axis direction of the first object to the end direction. That is, the pressing force of the curved portion is lower than the pressing force of the flat portion.

On the other hand, in the case of the example, the pressing force in the Y-axis direction is more uniform than that of the comparative example. That is, the pressing force of the curved portion is larger than that of the comparative example, the deviation of the pressing force of the flat portion and the pressing force of the curved portion is smaller than that of the comparative example, and the variation of the pressing force in the width direction (Y-axis direction) of the first object to be processed is compared to the comparative example. It is small compared.

From this, the pressing force applied to the curved portion CA of the first object S1 by the second pressing portion 6200 according to the first embodiment can be increased compared to the prior art, and the flat portion compared to the prior art. It can be seen that the (FA) and the curved portion (CA) can be uniformly pressed.

In addition, since the pressing device 6000 according to the third embodiment includes a plurality of second pressing parts 6200, even if the second pressing part 6200 is expanded less than the second embodiment, the first blood The pressing force can be sufficiently applied in the direction of the curved surface CA of the processed object S1.

Hereinafter, with reference to Figs. 1 to 8, the operation of the bonding facility according to the first embodiment of the present invention and the bonding process between the first to-be-processed object and the second to-be-processed object will be described.

First, as shown in FIG. 3, the first to-be-processed object S1 having a curved surface is supported on the jig 200, and the second to-be-processed object S2 is supported on the tray 410. Here, the second object to be processed (S2) includes a film (F) and a panel (P) attached to the film (F) to implement the image.

Thereafter, as shown in FIG. 4, the tray 410 is lowered to be positioned below the first pressing part 6100. Accordingly, the second to-be-processed object S2 has a convex shape having a higher height as it goes in the center direction in the width direction as in the shape of the first pressing portion 6100.

Thereafter, as shown in FIG. 5, the upper chamber 110 is lowered so that the chamber part 100 is sealed, so that the center of the width direction of the first object S1 and the center of the width direction of the second object S2 are in contact. As much as possible. When the chamber part 100 is sealed, the interior of the chamber part 100 is divided into an upper region and a lower region of the film F, based on the film F. In an embodiment, after the chamber part 100 is closed, the first pressure regulating part 310 and the second pressure regulating part 320 are respectively operated, so that the upper region of the film F and the lower region of the film F are operated. Each is created in a vacuum atmosphere.

Next, the lower region of the film F is reduced to atmospheric pressure using the second pressure adjusting unit 320. At this time, due to the pressure difference, the film (F) and the panel (P) attached thereto is pushed up in the direction in which the window (W) is positioned to press the window (W), and accordingly the primary bonding is performed.

Then, when the first pressing part 6100 is raised using the elevating driving part 620, as shown in FIG. 6, the movement is blocked by the jig 200 fixed to the upper side. Accordingly, a force is generated to push the second to-be-processed object S2 in the direction in which the first to-be-processed object S1 is located, wherein the first pressing part 6100 is applied to the shape of the first to-be-processed object S1.
