20120131959 | LASER SEALING DEVICE FOR GLASS SUBSTRATES - A laser sealing device for glass substrates includes a first laser head and a second laser head. The first laser head irradiates laser onto a sealing material coated between glass substrates, thereby melting the sealing material. The second laser head is provided at a predetermined interval from the first laser head, irradiates laser onto the portion which has been irradiated by the first laser head, and is set to a lower power than the first laser head. The device further includes a heating plate provided so as to be movable relative to the first and second laser heads and placed on the glass substrates when being heated to a predetermined temperature. Thus, it is possible to minimize the occurrence of cracking in the glass substrates due to thermal shock since the temperature of the sealing material which is melted by the laser heads drops slowly rather than rapidly. | 05-31-2012 |
