The transport mechanism has an arm for holding the LCD assembly, a first lift mechanism for vertical moving the arm, and a pre-alignment mechanism for receiving the LCD assembly and preliminary aligning the LCD assembly with the table. The pre-alignment mechanism has a plurality of support rollers for supporting the LCD assembly in a substantially horizontal position, four pairs of positioning rollers having axes intersecting at substantially right angles and located at level higher than the support rollers, for allowing the LCD assembly to fall naturally onto the support rollers and for holding corners of the LCD assembly, and a second lift mechanism for moving upwards the positioning rollers and the support rollers as the first lift mechanism moves the arm downwards.
