Problems solved by technology

Then, this substrate assembling apparatus according to the prior art removes the adhered substrate without considering whether the substrate has been adhered to the lower table, thereby having a high possibility of damaging the substrate.
[0011] Second, the bonded substrates must be removed without sagging in the center or peripheral portion of the bonded substrates
[0012] Third, the direct contact between the substrate and the workbench results in the generation of static electricity, which may damage the circuits formed on the substrate
Therefore, it is very likely that the substrate will be loaded in an incorrect position, and as such, misalignment may occur during its loading, thereby increasing the possibility that the substrate may be damaged

Embodiment Construction

[0035] Preferred embodiments of the invention will now be described in detail, examples of which are illustrated in the accompanying drawings.

[0036] Fig. 3 is a cross-sectional view of a typical substrate bonding apparatus according to the present invention. In FIG. 3, a substrate bonding apparatus for a liquid crystal display device may include a bonding chamber 110, an upper table 121 and a lower table 122, a table moving unit, a vacuum unit 200, a loading part 300, and a substrate lifting system 400 and a clamping system.

[0037]The bonding chamber 110 may include a structure suitable for performing a bonding process between substrates. The bonding chamber 110 may comprise a single chamber structure having an access door (not shown). On the other hand, the bonding chamber 110 may also include upper and lower parts (not shown in the figure), which facilitate loading / unloading of respective substrates. The upper and lower parts can move in both vertical and horizontal ...
