Polarization plate gluing apparatus

A polarization plate gluing apparatus employing a cleaning mechanism for cleaning a surface of a liquid crystal cell and a gluing mechanism for gluing a polarization plate to the surface of the liquid crystal cell, where the cleaning mechanism comprises:

• a plate for being pushed to the surface of the liquid crystal cell to move relative to the liquid crystal cell;
• a hood for covering space around the plate;
• and
• an absorption apparatus for absorbing air within the hood.

A polarization plate gluing apparatus comprising:

• a table for moving a liquid crystal cell among a carry-in station, a cleaning station, gluing station and a carry-out station;
• a carry-in mechanism for carrying the liquid crystal cell to the carry-in station;
• a cleaning mechanism for cleaning the surface of the liquid crystal cell at the cleaning station;
• a gluing mechanism for gluing a polarization plate to the surface of the liquid crystal cell at the gluing station;
• and
• a carry-out mechanism for carrying out the liquid crystal cell from the carry-out station, where the cleaning mechanism further comprises:
• an elastic plate for being pushed to th surface of the liquid crystal cell to relatively move to a lengthwise direction of the liquid crystal cell against the surface of the liquid crystal cell;
• a hood for covering space around the plate;
• and
• an absorption apparatus for absorbing air within the hood, and where,
• the gluing mechanism further comprises:
• a feeding mechanism for feeding a predetermined length of strip-shaped material substantially overlapped by a polarization plate and a carrier tape;
• a half-cutting mechanism for cutting only the polarization plate of the strip-shaped material;
• a glue head for absorbing the polarization plate cut by the half-cutting mechanism to feed the same to the surface of the liquid crystal cell;
• a retracting mechanism for retracting the strip-shaped material in a state where the polarization plate is absorbed and supported by the glue head;
• a winding mechanism for winding only the carrier tape after the polarization plate is removed;
• and
• a position determination mechanism for determining a position of the polarization plate against the glue head when the glue head absorbs the polarization plate.
