Disclosed are an absorber, in which the positions of absorption pads are automatically adjusted according to sizes of substrates, and an apparatus for fabricating a liquid crystal display panel having the same. The absorber includes an absorption plate gate attached to a robot arm having a transfer hand through a turn unit; and an absorption unit assembly mounted on the lower surface of the absorption plate, and the absorption unit assembly includes a middle absorption unit; a left absorption unit located at the left side of the middle absorption unit; a right absorption unit located at the right side of the middle absorption unit; an absorption support unit to guide moving routes of the absorption units and fix the absorption units to the absorption plate; and absorption pads respectively formed on the absorption units such that the positions of the absorption pads are adjusted according to sizes of substrates to allow the absorption pads to absorb the substrates.

Absorber and apparatus for fabricating liquid crystal display panel having the same

An apparatus for cutting liquid crystal display panels is disclosed in the present invention. The apparatus includes at least one table receiving bonded mother substrates having a plurality of unit liquid crystal display panels, at least one cutting wheel forming a scribing line on a surface of the bonded mother substrates, and a suction unit coupled to the at least one cutting wheel and sucking in glass debris on the surface of the bonded mother substrates.

Apparatus for cutting liquid crystal display panel

A cut section checking/aligning unit simultaneously checks cut sections of unit liquid crystal display panels that are separated from within first and second base substrates and aligns the unit liquid crystal display panels to a reference position. A grinding unit grinds edges of the unit liquid crystal display panels. The cut section checking/aligning unit and the grinding unit are integrated within a grinding device.

Apparatus for fabricating liquid crystal display panels

An apparatus for conveying a liquid crystal display panel for moving various size unit liquid crystal display panels. The present invention includes a horizontal driving unit controlling a revolution of a motor, a plurality of screw shafts protruding out of the horizontal driving unit. A pair of robot arms having first and second ends, the first ends are supported by corresponding screw shafts and extend from the screw shafts, and a plurality of clamping units connected to the second ends of the robot arms.

Method for fabricating liquid crystal display panels

An apparatus for measuring ground amounts of a liquid crystal display panel includes a grinding unit for grinding upper and lower marginal portions of a unit liquid crystal display panel, a first imaging system for producing images of a ground surface of the upper marginal portion of the unit liquid crystal display panel, and a second imaging system for producing images of a ground surface of the lower marginal portion of the unit liquid crystal display panel.

Apparatus and method for measuring ground amounts of liquid crystal display panel

In an apparatus and a method for correcting a grinding amount of a unit liquid crystal display panel, by grinding an edge of a unit liquid crystal display panel; generating grinding pictures of the unit liquid crystal display panel; calculating an error value by comparing the grinding pictures with a reference picture; and changing a set value of a grinding unit according to the error value. In addition, by disposing a grinding amount correcting apparatus in a grinding apparatus, correcting a grinding amount of a unit liquid crystal display panel can be performed by an automatic system.

Apparatus and method for correcting grinding amount of liquid crystal display panel

An aligning apparatus includes a loading plate to load at least one alignment object; first and second alignment bars to align the at least one alignment object loaded on the loading plate, wherein the first and second alignment bars are bent by a force greater than a threshold value when contacting the alignment object; and at least one driving unit to drive the first and second alignment bars in close and open directions toward and away from each other.

Aligning apparatus

An apparatus for convening a liquid crystal display panel for moving various size unit liquid crystal display panels. The present invention includes a horizontal driving unit controlling a revolution of a motor, a plurality of screw shafts protruding out of the horizontal driving unit. A pair of robot arms having first and second ends, the first ends are supported by corresponding screw shafts and extend from the screw shafts, and a plurality of clamping units connected to the second ends of the robot arms.

Disclosed is a device for grinding a liquid crystal display panel improving the efficiency of using equipment by independently operating first and second grinding units for grinding the unit liquid crystal display panel. The present invention includes a first grinding unit grinding edges of short or long sides of the unit liquid crystal display panel in a normal mode and a second grinding unit grinding the edges of the short or long sides of the unit liquid crystal display panel that are not ground by the first grinding unit in the normal mode or grinding the edges of the long and short sides of the unit liquid crystal display panel in an emergency mode.
