The separation of the inversion unit 130 and the lifting unit 140 is the second chamber 120 by the vacuum pressure when forming a vacuum pressure of the bonding space formed by the first chamber 110 and the second chamber 120 to be proceeded later In order to prevent the excessive force is transmitted to the lifting unit 140 by the movement (or deformation) of).

On the other hand, when the bonding space formed by the first chamber and the second chamber is formed, exhaust of the bonding space is performed and the bonding space is converted into a vacuum state. At this time, alignment between the display panel D and the stereoscopic lens panel P is performed.

Here, the alignment between the display panel D and the stereoscopic lens panel P may be performed by the camera 124. The camera 124 receives illumination from the lighting device 115 and photographs an alignment mark (not shown) formed on the display panel D and the stereoscopic lens panel P. FIG. In this case, the linear actuators 122 adjust the second stage 121 back, front, left, and right according to the photographing result, and perform alignment between the display panel D and the stereoscopic lens panel P. FIG.

On the other hand, when the bonding space is switched to this vacuum state, the three-dimensional lens panel P attached to the second stage 121 is dropped to the upper portion of the display panel (D). When the three-dimensional lens panel P is in contact with the display panel (D), the process gas is injected into the bonding space to attach the display panel (D) to the display panel (step S150).

That is, as the process gas is injected into the bonding space, the three-dimensional lens panel P is displayed by the space between the display panel D and the stereoscopic lens panel P and the pressure difference generated in the bonding space. Is pressed to the side.

Here, the at least one of the display panel (D) and the three-dimensional lens panel (P) is applied with a sealant (S) in advance, or the display panel (D) and the three-dimensional lens panel (P) seated on each stage (111, 121) The sealant (S) may be applied to).

On the other hand, as the stereoscopic lens panel P is pressed toward the display panel D, the stereoscopic lens panel P is bonded to the display panel D by the sealing agent S. As shown in FIG. The display panel D and the stereoscopic lens panel P to be bonded are provided as the bonding panel D + P. The bonding panel D + P stays on the first stage 111, the curing module 123 irradiates ultraviolet rays toward the bonding panel D + P, and the sealing agent S is cured according to the ultraviolet irradiation.

When the sealing agent S is cured by ultraviolet irradiation, the lifting unit 140 raises the second chamber 120 to open the bonding space.

At this time, as the lifting unit 140 is raised, the support bar 141 of the lifting unit 140 supports the inverting unit 130 of the second chamber 120, and the seating groove 144 of the support bar 141. As the seating jaw 133 of the inversion unit 130 is fastened, the second chamber 120 is raised.
