Abstract:
1. A sealant hardening apparatus for an LCD panel comprising: a stage on which substrates bonded by a plurality of sealant lines are loaded, for being moved in an in-line method; a mask provided above the bonded substrates, having a plurality of open lines corresponding to only the plurality of sealant lines to transmit the light, and a closed part corresponding to the remaining portions to prevent the light, wherein each of the plurality of sealant lines is formed of a closed loop and each of the plurality of open lines is formed of a closed loop corresponding to the each sealant line; four aligning cameras above four corners of the mask for aligning the mask and the bonded substrates, wherein two aligning cameras, provided diagonally in the four aligning cameras, firstly align the mask and the bond substrates and then, if the mask and the bonded substrates are misaligned, the four aligning cameras realign the mask and the bonded substrates; a lamp irradiating ultra-violet (UV) rays of high energy; a plurality of optical fibers transmitting UV rays of the lamp; and a UV irradiation part arranging and supporting the plurality of optical fibers in a single liner arrangement and irradiating the UV rays from the plurality of optical fibers to the bonded substrates through the mask so as to harden the plurality of sealant lines, wherein the UV irradiation part includes: wherein the condensing lens is positioned over the mask so a length direction of the condensing lens is parallel with a short-side direction of the mask.
