Apparatus for filling up a liquid crystal injection hole in a LCD cell and method of doing the same having a detector of resin location in an injection hole

An apparatus for filling up a hole formed with a liquid crystal display cell for introducing liquid crystal into said liquid crystal display cell therethrough, comprising:

• (a) a cell holder for holding a liquid crystal display cell therewith;
• (b) a cell positioner for driving said cell holder in such a manner that a hole formed with said liquid crystal display cell for introducing liquid crystal into said liquid crystal display cell therethrough, is upwardly directed;
• (c) a resin applicator for applying a resin to said hole for filling up said hole with said resin, said resin being to be cured when ultraviolet ray is radiated thereto;
• (d) a location detector for detecting a location in said hole where said resin reaches;
• and
• (e) a ultraviolet ray radiator for radiating ultraviolet ray to said resin when said location detector detects that said resin reaches a predetermined location.

An apparatus for filling up a hole formed with a liquid crystal display cell for introducing liquid crystal into said liquid crystal display cell therethrough, comprising:

• (a) a cell holder for holding at least two liquid crystal display cells therewith;
• (b) a cell positioner for driving said cell holder in such a manner that holes formed with said liquid crystal display cells for introducing liquid crystal into said liquid crystal display cells therethrough, are upwardly directed;
• (c) a resin applicator for applying a resin to said holes for filling up said holes with said resin, said resin being to be cured when ultraviolet ray is radiated thereto;
• (d) location detectors in the same number as that of said liquid crystal display cells for detecting a location in each of said holes where said resin reaches;
• and
• (e) ultraviolet ray radiators in the same number as that of said liquid crystal display cells for radiating ultraviolet ray to said resin when said location detectors detect that said resin reaches a predetermined location,
• one of said location detectors and one of said ultraviolet ray radiators being associated with one of said liquid crystal display cells.

A method of filling up a hole formed with a liquid crystal display cell for introducing liquid crystal into said liquid crystal display cell therethrough, comprising the steps, in sequence, of:

• (a) holding a liquid crystal display cell formed with a hole for introducing liquid crystal into said liquid crystal display cell therethrough;
• (b) directing said hole upwardly;
• (c) applying a resin to said hole, said resin being to be cured when ultraviolet ray is radiated thereto;
• (d) detecting a location where said resin reaches in said hole;
• and
• (e) radiating ultraviolet ray to said resin when said resin is detected to reach a predetermined position in said hole.
