Glass welding method

摘要

A glass layer 3 is disposed between a glass member 4 and a thermal conductor 7 along a region to be fused. The glass layer 3 is formed by removing an organic solvent and a binder from the paste layer while using the thermal conductor 7 as a hotplate. Then, a laser beam L1 is emitted while using the thermal conductor 7 as a heatsink, so as to melt the glass layer 3, thereby burning and fixing the glass layer 3 onto the glass member 4. Thereafter, another glass member is overlaid on the glass member 4 having the glass layer 3 burned thereonto, such that the glass layer 3 is interposed therebetween. Then, the region to be fused is irradiated therealong with a laser beam, so as to fuse the glass members together.

1. A glass fusing method for manufacturing a glass fusing structure by fusing first and second glass members together, the method comprising the steps of:
forming a paste layer on a thermal conductor along a region to be fused, the paste layer containing a glass powder, a laser-absorbing material, an organic solvent and a binder; removing the organic solvent and the binder from the paste layer by using the thermal conductor as a hotplate, so as to form a glass layer on the thermal conductor; overlaying the first glass member on the thermal conductor formed with the glass layer while interposing the glass layer therebetween, so as to dispose the glass layer between the first glass member and the thermal conductor; irradiating the region to be fused therealong with a first laser beam while using the thermal conductor as a heatsink, so as to melt the glass layer disposed between the first glass member and the thermal conductor, and fix the glass layer to the first glass member, the thermal conductor is situated so that it contacts the glass layer during the irradiation process; removing the thermal conductor from the glass layer; and overlaying the second glass member on the first glass member having the glass layer fixed thereto such that the glass layer is interposed therebetween, and irradiating the region to be fused therealong with a second laser beam, so as to fuse the first and second glass members together.
