Abstract
A device for cutting a liquid crystal display panel includes a first scribing unit for forming a first scribing line at first and second mother substrates by using first and second wheels and pressing at least a portion of the first scribing line with a first roll, a second scribing unit for forming a second scribing line at the first and second mother substrates by using third and fourth wheels and pressing at least a portion of the second scribing line with a second roll, and a first rotating unit for rotating the first and second mother substrates to form the second scribing line.
Claims26
A device for cutting a liquid crystal display panel, comprising:
- a first scribing unit for forming a first scribing line at first and second mother substrates by using first and second wheels and pressing at least a portion of the first scribing line with a first roll;
- a second scribing unit for forming a second scribing line at the first and second mother substrates by using third and fourth wheels and pressing at least a portion of the second scribing line with a second roll;
- and
- a first rotating unit for rotating the first and second mother substrates to form the second scribing line.
A device for cutting a liquid crystal display panel comprising:
- a first scribing unit for loading and holding first and second mother substrates between first and second tables, forming a first scribing line on first and second mother substrates with first and second wheels, and cutting the first and second mother substrates by moving the first and second tables;
- a first rotating unit for rotating the first and second mother substrates by 90°;
- and
- a second scribing unit for loading and holding the first and second mother substrates between third and fourth tables, forming a second scribing line on the first and second mother substrates with the third and fourth wheels to cut the first and second mother substrates by moving the third and fourth tables.
A method for cutting a liquid crystal display panel, comprising:
- forming a first scribing line at first and second mother substrates;
- pressing at least a portion of the first scribing line with a first roll to cut the first and second mother substrates;
- forming a second scribing line at the first and second mother substrates;
- and
- pressing at least a portion of the second scribing line with a second roll to cut the first and second mother substrates.
A method for cutting a liquid crystal display panel, comprising:
- loading and holding first and second mother substrates between first and second tables;
- forming a first scribing line at first and second mother substrates;
- cutting the first and second mother substrates by moving the first and second tables;
- loading and holding the first and second mother substrates between third and fourth tables;
- forming a second scribing line at the first and second mother substrates;
- and
- cutting the first and second mother substrates by moving the third and fourth tables.
A method for cutting a liquid crystal display panel, comprising:
- holding first and second mother substrates to protrude a dummy region of the first and second mother substrates from a first table;
- forming a first scribing line at the protruded first and second mother substrates with first upper and lower wheels;
- removing the dummy region from the first and second mother substrates along the first scribing line by using a robot grip;
- moving the first and second mother substrates without the dummy region between the first and second tables spaced apart from each other to form a second scribing line at the first and second mother substrates by using the first upper and lower wheels;
- and
- moving the first and second tables to cut the first and second mother substrates.
