Korean Team Develops Robot to Help Produce 5G LCDS

09 December 2002

The Korea Advanced Institute of Science and Technology (KAIST) has developed an ultra light robot made of highly-stiff carbon fiber epoxy composite to help manufacture fifth-generation (5G) liquid crystal displays (LCDs).

KAIST's Mechanical Engineering Department research team, led by Dr. Lee Dai-gil, developed the new material composite robot in collaboration with Lacomtech and Iramtech. The robot can work in a clean room not allowed to human beings as they might raise minute particles of dust, something which LCDs are susceptible to.

The new material, mainly used in the aerospace industry, is much lighter and stiffer than currently used aluminum to make the clean room robot.

The fifth-generation LCD is 1.25-meter long, 1.1-meter wide and 0.7-millimeter thick so existing robots have some difficulties to handle the ultimately thin and fragile 5G LCDs. To hold and move them fast and effectively, the composite sandwich structure is applied to the new robot to make it lighter by 45 percent, more silent and safer. Overseas demand for the robot is expected to rise because of its high quality, slashing imports of Japanese robots and robot parts, the officials said..

""That's because the epoxy composite robot is also available not only to the production of 5G LCDs but to the fields of nano-technology (NT) and bio-technology (BT) in which semiconductor, multimedia and pharmaceutical firms, hospitals and foods companies have an interest,"" said Lee, chief developer of the robot.

Lee, whose major fields are composite materials and machine tools, developed in 1998 a new materials robot for the fourth-generation LCD manufacturing process, collaborating with Meerae Engineering for the first time in the world.
