Abstract
A liquid crystal display device bonding apparatus includes a chamber part for bonding substrates together, a plurality of moving elements within the chamber part, and at least one origin verifying system provided along moving paths of the moving elements.
Claims10
A liquid crystal display device bonding apparatus, comprising:
- a chamber part for bonding substrates together;
- a plurality of moving elements within the chamber part;
- and
- at least one origin verifying system provided along moving paths of the moving elements
- wherein the origin verifying system includes a contact part having one end fixed to an inside of the chamber part for contacting at least one of the moving elements, and a contact confirming part attached to the at least one of the moving elements for sensing contact with the contact part.

A liquid crystal display device bonding apparatus, comprising:
- a chamber part for bonding substrates together;
- a plurality of moving elements within the chamber part;
- and
- at least one origin verifying system provided along moving paths of the moving elements,
- wherein the origin verifying system includes a dial gauge for visual sensing contact between the moving elements and the origin verifying system.
2 more elements
A liquid crystal display device bonding apparatus, comprising:
- a chamber part for bonding substrates together;
- a plurality of moving elements within the chamber part;
- and
- at least one origin verifying system provided along moving paths of the moving elements,
- wherein the origin verifying system includes a position confirming sensor for sensing and displaying a position of the moving elements in a preset direction.
2 more elements
A method for setting an origin in a liquid crystal display device bonding apparatus, comprising the steps of:
- moving a moving element toward an origin verifying system;
- reading a position of the moving element at a preset location;
- and
- resetting the preset location as an origin of the moving element when the moving element reaches the preset location,
- wherein the reading step includes reading contact of the moving element with the origin verifying system, and
- wherein the step of reading contact of the moving element with the origin verifying means includes reading production of a tensile load.
