The present invention relates to a glass fusing method which manufactures a glass fusing structure by fusing glass members together and a glass layer fixing method therefor.
Known as a conventional glass fusing method in the above-mentioned technical field is a method which burns a glass layer containing organic matters (organic solvents and binders), a laser-light-absorbing material, and a glass powder onto one glass member along a region to be fused, then superposes the other glass member on the one glass member with the glass layer interposed therebetween, and irradiates the glass layer with laser light along the region to be fused, so as to fuse the glass members to each other.
Meanwhile, for fixing the glass layer to a glass member, techniques for removing the organic matters from the glass layer by irradiation with laser light instead of heating in a furnace have been proposed (see, for example, Patent Literatures 1 and 2). Such techniques can prevent functional layers and the like formed on glass members from being worsened by heating and inhibit the energy consumption from being increased by the use of the furnace and the heating time from becoming longer in the furnace.
However, there has been a case where fixing a glass layer to a glass member by irradiation with laser light (so-called temporary firing) and then fusing glass members to each other with the glass layer interposed therebetween by irradiation with laser light (so-called final firing) makes the fusing state nonuniform and leaves the glass powder of the glass layer as a contaminant, thereby lowering the reliability of the glass fusing structure.
In view of such circumstances, it is an object of the present invention to provide a glass fusing method which can manufacture a highly reliable glass fusing structure and a glass layer fixing method therefor.
For achieving the above-mentioned object, the inventor conducted diligent studies and, as a result, has found out that the fusing state becomes nonuniform and the glass powder of the glass layer is left as a contaminant because of the fact that the laser light absorptance of the glass layer drastically increases when the temperature of the glass layer exceeds its melting point Tm as illustrated in
That is, in the glass layer arranged on the glass member, scattering of light exceeding the absorption characteristic of the laser-light-absorbing material occurs because of the particle property of the glass powder and the like, so as to place it into a lower laser light absorptance state (e.g., it looks whiter under visible light). When the glass layer is irradiated with laser light in such a state with a laser power P so that the glass layer attains a temperature Tp higher than the melting point Tm but lower than its crystallization temperature Tc as illustrated in
When the glass layer is irradiated with laser light at such a laser power as to melt but not crystallize the glass layer in a peripheral part of its irradiation region in view of the above in the case where the beam profile of the laser light has a Gaussian distribution, the temperature reaches the crystallization temperature Tc at a center part 30a at which the intensity of the laser light becomes relatively high in a glass layer 30 as illustrated in
When the glass layer is irradiated with laser light at such a laser power as to melt but not crystallize the glass layer in the center part of its irradiation region in the case where the beam profile of the laser light has a Gaussian distribution, on the other hand, the temperature does not reach the melting point Tm at both edge parts 30b at which the intensity of the laser light becomes relatively low in the glass layer 30 as illustrated in
Based on the foregoing findings, the inventor has conducted further studies and completed the present invention. That is, the glass fusing method in accordance with the present invention is a glass fusing method for manufacturing a glass fusing structure by fusing first and second glass members to each other, the method comprising the steps of arranging a glass layer containing a laser-light-absorbing material and a glass powder with a predetermined width on the first glass member along an extending region to be fused; irradiating the glass layer with first laser light while relatively moving an irradiation region of the first laser light along the region to be fused, so as to melt the glass layer, thereby fixing the glass layer to the first glass member; and superposing the second glass member on the first glass member having the glass layer fixed thereto with the glass layer interposed therebetween and irradiating the glass layer with second laser light, so as to fuse the first and second glass members to each other; wherein the irradiation region of the first laser light is shaped like a ring, the glass layer being irradiated with the first laser light such that, in a width direction of the glass layer, two peaks in a beam profile of the first laser light respectively overlap both edge parts of the glass layer. The glass layer fixing method in accordance with the present invention is a method for manufacturing a glass-layer-fixed member by fixing a glass layer to a first glass member, the method comprising the steps of arranging the glass layer containing a laser-light-absorbing material and a glass powder with a predetermined width on the first glass member along an extending region to be fused; and irradiating the glass layer with first laser light while relatively moving an irradiation region of the first laser light along the region to be fused, so as to melt the glass layer, thereby fixing the glass layer to the first glass member; wherein the irradiation region of the first laser light is shaped like a ring, the glass layer being irradiated with the first laser light such that, in a width direction of the glass layer, two peaks in a beam profile of the first laser light respectively overlap both edge parts of the glass layer.
In the glass fusing method and glass layer fixing method, the glass layer is irradiated with the first laser light having a ring-shaped irradiation region when melting the glass layer and fixing it to the first glass member. The glass layer is irradiated with the first laser light such that, in the width direction of the glass layer, two peaks in the beam profile of the first laser light respectively overlap both edge parts of the glass layer. This allows the center part and each of both edge parts of the glass layer to be irradiated for shorter and longer times with a part having a relatively high intensity in the first laser light, respectively. As a consequence, the amount of heat input by irradiation with the first laser light is homogenized between the center and both edge parts in the glass layer. This can prevent the center part of the glass layer from crystallizing and the unmolten glass powder from remaining near the edge parts of the glass layer, so as to melt the center and edge parts of the glass layer appropriately. Hence, the glass fusing method and glass layer fixing method can manufacture a highly reliable glass fusing structure.
Preferably, in the glass fusing method in accordance with the present invention, the glass layer is irradiated with the first laser light such that, in the width direction of the glass layer, peak values of the two peaks are located on the outside of the respective edge parts of the glass layer. In this case, even when the irradiation region of the first laser light somewhat shifts with respect to the glass layer in the width direction thereof, the intensity of the first laser light is higher in both edge parts of the glass layer than in the center part thereof. This can reliably prevent the unmolten glass powder from remaining near the edge parts.
Preferably, in the glass fusing method in accordance with the present invention, the glass layer is irradiated with the first laser light through the first glass member from the first glass member side. This fully heats a part of the glass layer on the first glass member side and thus can improve the adhesion of the glass layer to the first glass member. Further, the part of the glass layer on the side opposite from the first glass member (i.e., the part of the glass layer fused to the second glass member) is prevented from being crystallized by excess heat input, whereby the fusing state of the glass layer with respect to the second glass member can be made uniform.
Preferably, the glass fusing method in accordance with the present invention further comprises the step of irradiating a part of the glass layer arranged on the first glass member with third laser light before the step of fixing the glass layer to the first glass member, so as to melt a part of the glass layer, thereby forming a laser-light-absorbing part in the glass layer; and the step of fixing the glass layer to the first glass member irradiates the glass layer with the first laser light while relatively moving the irradiation region of the first laser light along the region to be fused from the laser-light-absorbing part acting as an irradiation start position.
As mentioned above, the laser light absorptance of the glass layer arranged on the first glass member drastically increases when the glass layer melts. Hence, when the irradiation region of laser light is just relatively moved along the region to be fused in order to melt the glass layer arranged on the first glass member, a region in an unstable state where the glass layer is not molten in the whole width thereof appears from the irradiation start position of the laser light to a region in a stable state where the glass layer is molten in the whole width thereof. However, irradiating the glass layer with laser light at such a laser power as to melt the glass layer in the whole width thereof at the irradiation start position of the laser light may crystallize the glass layer by excess heat input.
Therefore, before melting the glass layer so as to fix it to the first glass member, a part of the glass layer is irradiated with the third laser light, so as to melt a part of the glass layer, whereby a laser-light-absorbing part having a laser light absorptance higher than that in a part not irradiated with the third laser light is formed beforehand in the glass layer. Then, using the laser-light-absorbing part as the irradiation start position, the glass layer is irradiated with the first laser light while relatively moving the irradiation region of the first laser light along the region to be fused. Since the irradiation start position of the first laser light thus has already become the laser-light-absorbing part, a region in a stable state in which the glass layer is molten in the whole width thereof can be formed immediately after near the start point for beginning irradiation with the first laser light. Therefore, the glass layer is not required to be irradiated with laser light at such a laser power as to crystallize it. Since the first and second glass members are fused to each other through the glass layer in such a stable state, the fusing state can be made uniform.
The present invention can manufacture a highly reliable glass fusing structure.
In the following, preferred embodiments of the present invention will be explained in detail with reference to the drawings. In the drawings, the same or equivalent parts will be referred to with the same signs while omitting their overlapping descriptions.
As illustrated in
A glass fusing method (including a glass layer fixing method of producing a glass-layer-fixed member by fixing the glass layer 3 to the glass member 4 in order to manufacture the glass fusing structure 1 by fusing the glass members 4, 5 to each other) for manufacturing the glass fusing structure 1 will now be explained.
First, as illustrated in
Subsequently, the paste layer 6 is dried, so as to remove the organic solvent. This arranges the glass layer 3 with a predetermined width on the glass member 4 along the ring-shaped region to be fused R extending like a rectangular ring. That is, the glass layer 3 contains the binder, laser-light-absorbing pigment, and glass frit 2. Scattering of light exceeding the absorption characteristic of the laser-light-absorbing pigment occurs because of the particle property of the glass frit 2 and the like in the glass layer 3 arranged on the surface 4a of the glass member 4, thereby placing it into a lower laser light absorptance state (e.g., the glass layer 3 looks whiter under visible light).
Next, as illustrated in
Thereafter, as illustrated in
Subsequently, as illustrated in
Here, as illustrated in
At the time of temporary firing for the glass layer 3, the irradiation with the laser light L2 starts from the laser-light-absorbing part 8a having enhanced the laser light absorptance beforehand acting as the irradiation start position, so that the glass layer 3 melts in the whole width thereof immediately after the irradiation start position. This reduces an unstable region with unstable melting of the glass layer 3 and yields a stable region with stable melting of the glass layer 3 in the whole region to be fused R. Since the remaining three corners are also provided with the laser-light-absorbing parts 8b to 8d, respectively, the corners on which loads are likely to be exerted when functioning as the glass fusing structure reliably melt at the time of temporary firing. In the glass layer 3 fixed to the surface 4a of the glass member 4, the glass frit 2 melts, thereby losing its particle property and so forth in the whole region to be fused R, so that the absorption characteristic of the laser-light-absorbing pigment appears remarkably, thus yielding a higher laser light absorptance state.
Subsequently to the temporary firing for the glass layer 3, the glass member 5 is superposed on a glass-layer-fixed member 10 (i.e., the glass member 4 having the glass layer 3 fixed thereto) with the glass layer 3 interposed therebetween as illustrated in
As explained in the foregoing, the glass fusing method (including the glass layer fixing method) for manufacturing the glass fusing structure 1 irradiates the glass layer 3 with the laser light L2 having a ring-shaped irradiation region when melting the glass layer 3 so as to fix it to the glass member 4 (i.e., at the time of temporary firing). The glass layer 3 is irradiated with the laser light L2 such that the two peaks M in the beam profile of the laser light L2 respectively overlap both edge parts 3b in the width direction of the glass layer 3. This allows the center part 3a and each of both edge parts 3b of the glass layer 3 to be irradiated for shorter and longer times with a part having a relatively high intensity in the laser light L2, respectively, as illustrated in
When fusing the glass members 4, 5 to each other (i.e., at the time of final firing), such a state that the fusing state becomes nonuniform or the glass frit 2 of the glass layer 3 remains as a contaminant does not occur as long as the temporary firing is performed reliably even if both edge parts 3b of the glass layer 3 do not melt completely, for example. The state of temporary firing of the glass layer 3 thus influences the state of final firing of the glass layer 3, so that the irradiation condition of laser light for temporary firing becomes severer than that for final firing.
The glass layer 3 is irradiated with the laser light L2 such that, in the width direction of the glass layer 3, peak values Mp of the two peaks M are located on the outside of the respective edge parts 3b. In this case, even when the irradiation region of the first laser light somewhat shifts with respect to the glass layer 3 in its width direction, e.g., from a position P0 to a position P1 or P2 as illustrated in
The glass layer 3 is irradiated with the laser light L2 through the glass member 4 from the glass member 4 side. This fully heats a part of the glass layer 3 on the glass member 4 side and thus can improve the adhesion of the glass layer 3 to the glass member 4. Also, the part of the glass layer 3 on the side opposite from the glass member 4 (i.e., the part of the glass layer 3 fused to the glass member 5) is prevented from being crystallized by excess heat input, whereby the fusing state of the glass layer 3 with respect to the glass member 5 can be made uniform.
Before fixing the glass layer 3 to the glass member 4 (i.e., before temporary firing), a part of the glass layer 3 is irradiated with the laser light L1, so as to form the laser-light-absorbing part 8a in the glass layer 3, and the glass layer 3 is irradiated with the laser light L2 at the time of temporary firing while relatively moving the irradiation region of the laser light L2 along the region to be fused R from the laser-light-absorbing part 8a acting as the irradiation start position. Since the irradiation start position of the laser light L2 thus has already become the laser-light-absorbing part 8a, a region in a stable state in which the glass layer 3 is molten in the whole width thereof can be formed immediately after near the start point for beginning irradiation with the laser light L2. Therefore, the glass layer 3 is not required to be irradiated with the laser light L2 at such a laser power as to crystallize it. Since the glass members 4, 5 are fused to each other through the glass layer 3 in such a stable state, the fusing state can be made uniform in the glass fusing structure 1.
The present invention is not limited to the above-mentioned embodiment. For example, the glass layer 3 may be irradiated with the laser light L2 for temporary firing not through the glass member 4, but from the side opposite from the glass member 4.
The glass layer 3 to be irradiated with the laser light L2 for temporary firing is not limited to one containing the binder, laser-light-absorbing pigment, and glass frit 2, but may be one corresponding to the paste layer 6 containing the organic solvent, binder, laser-light-absorbing pigment, and glass frit 2 or one containing the laser-light-absorbing pigment and glass frit 2 without the organic solvent and binder. The glass frit 2 is not limited to one having a melting point lower than that of the glass members 4, 5, but may have a melting point not lower than that of the glass members 4, 5. The laser-light-absorbing pigment may be contained in the glass frit 2 itself.
The present invention can manufacture a highly reliable glass fusing structure.
