Method of manufacturing a liquid crystal display module
Disclosed is a robot for transferring a substrate, wherein the robot has a robot arm, a hand part, which includes a plurality of plates. A plurality of pins protrude from the plates such that each pin may be folded downward. The pins include a rubber or resin with thermally insulating properties. By selectively folding down a certain number of the pins, contact may be minimized between the substrate and the robot, thereby preventing damage to the substrate such as thermally-induced defects and stains.
1. A method of manufacturing an LCD module, comprising:
forming a plurality of thin film transistors and pixel electrodes on a first substrate;
providing a second substrate;
bonding the first substrate to the second substrate; and
injecting a liquid crystal between the first and second substrates,
wherein forming a plurality of thin film transistors and pixel electrodes includes unloading the first substrate from a cassette using a robot having a plurality of pins, wherein unloading the first substrate includes: selecting a subset of pins from the plurality of pins for contacting the substrate, wherein selecting is based on the temperature sensitivity of the substrate;
folding down a remaining subset of pins from the plurality of pins; and
placing the first substrate in contact with the subset of pins;
wherein the robot includes a robot arm and a hand part mounted at a fore end of the robot arm;
wherein the hand part includes a connector having a side connected to the robot arm, at least two plates being connected to the second side of the connector opposite the side connected to the robot arm and having supporting devices and a plurality of guides formed at the positions on the plates corresponding to four corners of a substrate;
wherein the plurality of the pins are formed on the supporting devices,
wherein the remaining subset of pins are folded down by rotating the supporting devices on which the remaining subset of pins are formed, and
wherein the remaining subset of pins have shapes reversed from the selected subset pins.
