Glass support pin
A glass support pin for supporting a glass substrate for use with a liquid crystal display device is provided. In one embodiment, the glass support pin includes a plurality of branch pins, and one or more elastic members. The plurality of branch pins is structured to have top ends. The top ends of the branch pins are spread outwardly in the radial direction. The one or more elastic members are attached to the branch pins. The glass support pin is open by pulling the top ends of the branch pins outwardly according to a longitudinal movement of the glass support pin.
1. A carrier plate which operates to deliver a glass substrate for use with a liquid crystal display device, comprising:
a plurality of glass support pins, a glass support pin structured to support the glass substrate and including a plurality of branch pins wherein the glass support pin is opened to separate the branch pins and is closed to adjoin the branch pins according to its longitudinal movement, wherein the each branch pin is structured to have a top surface which is:
substantially facing away from the rest of the branch pin at an outermost tip of the branch pin in the longitudinal direction,
substantially parallel to the glass substrate when the glass support pin is open, and sloped downwards towards the central longitudinal axis of the glass support pin when the glass support pin is closed, and
configured to contact and to support the glass substrate at multiple positions as the glass support pin is open, and
a chuck comprising a plurality of openings which receives the plurality of glass support pins,
wherein as the glass support pin is lifted from the chuck, it is opened and as the glass support pin is inserted into an opening of the chuck, the glass support pin is closed.
2. The carrier plate of claim 1 , wherein a single glass support pin is configured to contact the glass substrate at multiple positions.
3. The carrier plate of claim 1 , wherein the opening of the chuck comprises an inner wall and the branch pins are pushed inwardly by the inner wall as the glass support pin is inserted into the opening of the chuck.
4. The carrier plate of claim 1 , wherein the glass support pin comprises a plurality of elastic members that moveably secures the branch pins.
5. The carrier plate of claim 3 , wherein the branch pins are spread outwardly as the glass support pin is lifted out of the opening of the chuck.
6. The carrier plate of claim 1 , wherein the opening of the chuck comprises an inner wall and the branch pins frictionally contact the inner wall as the glass support pin is inserted into the opening of the chuck.
7. A delivery system for use with a liquid crystal display device configured to be formed on a glass substrate, comprising:
a chuck structured to support the glass substrate wherein the glass substrate is vacuum-absorbed on the surface of the chuck; and
a plurality of glass support pins, a glass support pin comprising a plurality of branch pins which are spread outwardly as the glass support pin is lifted from the chuck and which are closed as the glass support pin moves toward the chuck wherein the glass support pin and the each branch pin are structured to have a top surface which is:
substantially facing away from the rest of the branch pin at an outermost tip of the branch pin in the longitudinal direction, substantially parallel to the glass substrate when the glass support pin is open, and sloped downwards towards the central longitudinal axis of the glass support pin when the glass support pin is closed, and
configured to contact and to support the glass substrate at multiple positions substantially simultaneously.
