Field of the Invention The present invention relates to a glass fusing method for producing a glass splicing body by fusing glass members to each other. [Prior Art] As a prior art glass fusing method in the above technical field, there is known a method in which a glass layer containing a laser light absorbing pigment is fired on a -glass member along a predetermined region of fusion, so that Further, the glass member is superposed on the glass member via a glass layer, and irradiates the laser light along the predetermined region to be welded, thereby welding one glass member to the other glass member (for example, refer to Patent Document 1). PRIOR ART DOCUMENT PATENT DOCUMENT Patent Document 1 Patent Publication No. 2006-524419 SUMMARY OF THE INVENTION Problems to be Solved by the Invention However, if glass members are welded to each other by irradiation of laser light, sometimes glass members may be Cracks occur. Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to provide a glass fusing method capable of producing a highly reliable glass fusing body. MEANS FOR SOLVING THE PROBLEMS The present inventors have made intensive studies to achieve the above object, and as a result, have found that the glass member is cracked in the fusion of the glass members irradiated with the laser light, as shown in FIG. If the temperature of the glass layer exceeds the melting point Tm when the light is emitted, the laser light absorption rate of the glass layer is rapidly increased. In other words, in the glass layer disposed between the glass members, the light scattering that exceeds the absorption characteristics of the laser light absorbing pigment due to the particle property of the glass frit becomes a state in which the laser light absorption rate is low (for example, in visible light). It looks like white.) Therefore, as shown in FIG. 12, when the laser light is irradiated with laser power so that the glass layer has a melting point Tm and a temperature Tp lower than the crystallization temperature Tc, the particles are melted by the glass frit. The property is damaged, etc. 'significantly exhibits the absorption characteristics of the laser light absorbing pigment'. The laser light absorption rate of the glass layer is rapidly increased (for example, it appears black or green under visible light). Thereby, the absorption of the above-mentioned laser light is caused in the glass layer, and the glass member is cracked due to the thermal shock caused by the excessive heat input. The inventors of the present invention have completed the present invention based on this finding. That is, the glass welding method of the present invention is characterized in that the first glass member and the second glass member are welded to each other to produce a glass frit, and the method includes the steps of: forming a glass layer containing the laser light absorbing material and the glass frit. Disposed on the first glass member along the pre-twisting region; and in a state in which the second glass member is superposed on the first glass member via the glass layer, the third heat is irradiated along the predetermined region of the fusion The input amount of the third laser light melts the glass layer, and when the melting rate of the glass layer in the direction perpendicular to the traveling direction of the first laser light exceeds a certain value, the heat input amount is switched from the first heat input to less than the first heat. The second heat input amount of the input amount is obtained, and the first glass member and the second glass member are welded by irradiating the third layer of the laser light with the second heat input amount along the predetermined region to be welded. 150763.doc 201117909 In the glass fusing method, when the third layer of the first laser beam having the first heat input amount is irradiated along the predetermined region of the fusion when the third layer of the laser beam is irradiated by irradiating the thunder laser light along the predetermined region of the fusion bonding, the glass is irradiated. The layer is melted, and when the melting rate of the glass layer in the direction intersecting with the traveling direction of the laser light exceeds a specific value, by switching the heat input amount, the irradiation along the predetermined region of the fusion has less than the first heat input amount. The second heat input amount of the first laser light is melted, and the glass layer is melted to weld the first glass member and the second glass member. When the glass layer is melted, if the brightness of the glass layer exceeds a certain enthalpy, the laser light absorption rate of the glass layer is rapidly increased, and then the second heat input having less than the i-th heat input amount is irradiated. The i-th laser light can therefore suppress the glass layer from becoming too hot. By switching the heat input amount, even if the i-th glass member and the second glass member are welded by the irradiation of the i-th laser light, it is possible to prevent breakage of the glass member such as cracks in the glass member. Therefore, according to the glass splicing method, it is possible to prevent cracks from occurring in the i-th glass member and the second glass member, and to manufacture a highly reliable glass (four) joint. Furthermore, the term "in the heat input" is the energy density of the first laser light in the irradiation area. Further, the "fourth rate of the glass layer" is the ratio of the "width of the fused portion of the glass layer" to the "wide width of the glass layer" in the direction in which the direction of the i-thin light travels. In the glass (four) connection method of the invention, it is preferable to switch from the ith heat input amount to the 28th input amount by lowering the first light emission rate. Here, the switching of the heat input amount is performed by the decrease in the irradiation power, and the first heat input amount is switched to the second heat input amount. In the moon glass splicing method, it is preferable to switch from the second heat input amount to the second track input amount by increasing the traveling speed of the glass layer by the first laser light phase 150763.doc 201117909. In this case, # is switched by the increase in the traveling speed of the i-th laser light, so that the first heat input amount can be reliably switched from the first heat input amount to the second heat input amount. Further, since the switching is performed by increasing the traveling speed, the time required for fixing the glass layer can be shortened. In addition, the "speed of travel of the first laser light with respect to the glass layer" means the relative traveling speed of the i-th laser light, #includes the case where the third laser light is fixed and the glass layer moves, and the glass layer is fixed and the thunder is fixed. The case where the light is moved, the third laser light, and the glass layer are moved. In the glass fusing method of the present invention, it is preferable that the amount of heat input from the second enthalpy (four) is the second heat transfer amount after the irradiation of the laser light from the second ray is passed. In the case of (4), it is possible to easily switch from the first heat input amount to the second heat input amount by a simple method such as controlling the specific time obtained in advance. Further, in the case of the glass layer of the same configuration, the irradiation conditions of the #1#-lighting light are the same, the specific time can be made substantially the same, so that the glass layer of the same layer can be easily melted continuously or simultaneously, and can be improved. Manufacturing efficiency. In the glass fusing method of the present invention, it is preferable that the heat input amount from the glass layer is switched to the second heat input amount when the intensity of the heat radiation emitted from the glass layer rises to a specific value. In this case, by detecting the intensity of the heat radiation having an increase in the correlation with the increase in the melting rate of the glass layer, the heat input amount can be accurately switched. In the glass fusing method of the present invention, it is preferable that the intensity of the reflected light of the first laser light reflected by the glass layer is changed to a specific value, and the amount of heat input from the second heat is switched to the second heat input amount. In this case, by measuring the correlation between the decrease in the melting rate of the glass layer with the intensity of the reflected light of the glass 150763.doc 201117909, it is possible to accurately switch the heat input amount. Invention, Embodiments A glass frit having high reliability can be manufactured. In the following, the preferred embodiments of the present invention will be described in detail with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of a glass fusing body manufactured by an embodiment of the glass fusing method of the present invention. As shown in Fig. i, the glass frit is rigidly joined to the glass member 3, the crucible member (4) glass member 4, and the glass member (the second glass member) formed by the predetermined region R. The glass members 4, 5 are, for example, members having a rectangular plate shape having a thickness of not more than -7 Å, and the welding predetermined region R is formed in a rectangular ring shape along the outer edges of the glass members 4, 5. The glass layer 3 contains, for example, a low-melting glass (vanadium phosphate glass, lead borate glass, etc.) and is formed in a rectangular ring shape along the welding predetermined region R. Next, the glass fusing method for manufacturing the above-mentioned glass fusing body will be described. First, as shown in Fig. 2, the smeared layer 6 is formed on the surface 4a of the glass member 4 along the predetermined region R where the coating is applied by means of a dispenser or screen printing. The glass frit is, for example, a powdery glass frit containing a low-melting glass (vanadium phosphate glass, lead boric acid glass, etc.) (a laser light μ, an inorganic pigment such as iron oxide, that is, a laser light absorbing material (laser light absorbing material)) , acetic acid 150763.doc 201117909 organic solvent such as decyl ester, and the thermal decomposition of the glass below the softening point of the temperature of the tree glutinous rice ingredients (acrylic acid), that is, the binder is mixed. The glass paste can also be A low-melting point glass to which a laser light absorbing pigment (laser light absorbing material) is added in advance is a powdery glass frit (glass powder), an organic solvent, and a binder. That is, the slurry layer 6 contains a glass frit. 2. A laser light absorbing pigment, an organic solvent and a binder. Then, the slurry layer 6 is dried to remove the organic solvent, and the layer 6 is heated to remove the binder, whereby the glass layer 3 is formed along the predetermined region r of the fusion. The surface layer of the glass member 4 is fixed to the surface of the glass member 4. Further, the glass layer 3 fixed to the surface 4a of the glass member 4 is diffused beyond the absorption characteristics of the laser light absorbing pigment due to the particle property of the glass frit 2 or the like. a state in which the laser light absorption rate is low (for example, it appears white under visible light). Then, as shown in FIG. 3, the glass member 5 is superposed on the glass member 4 to which the glass layer 3 is fixed via the glass layer 3. Then, as shown in FIG. 4 to FIG. 6, the light-converging point is aligned with the irradiation start position a in the predetermined area of the glass layer 3, and the laser beam (first cloud-ray first) u is started to be irradiated.

In the unstable region of the crucible, the melting of the glass layer 3 does not propagate throughout the entire width direction, so the laser light absorption rate is not completely high. As shown in Fig. 8, the laser light L1 is a strong irradiation condition for crystallizing the glass layer 3 in the stable region, for example, the irradiation power of the laser light L1 is i〇w^ the first heat input amount. And start to shine. In addition, the heat input amount can be expressed by the following formula (1). In the present embodiment, the traveling speed or the spot diameter is solid 疋, so the heat input amount changes depending on the irradiation power. Heat input amount (J/mm2) = power density (JS/mm2 Bu travel speed (s)·., (i) Thereafter, if it reaches the stable region start position B, the glass layer 3 is melted throughout the entire width direction. In the stable region, the temperature of the glass layer 3 is equal to or greater than the melting point Tm, and the particle material is destroyed by the melting of the glass frit 2, and the absorption characteristics of the laser light absorbing pigment are remarkably exhibited. The light absorption rate increases sharply throughout the entire width direction, and the melting rate becomes close to 100% (for example, it appears to be broadly green under visible light). Thereby, the glass layer 3 causes the absorption of the above-mentioned laser light. And the heat input to the glass layer 3 becomes excessive. Therefore, as shown in Fig. 8, after the specific time X after the melting rate of the glass layer 3 becomes close to unm (or before), that is, the glass layer 3 After the entire width direction exceeds the melting point Tm and the laser light absorption rate is rapidly increased, the irradiation power of the laser light L1 is switched from the irradiation power 1 〇 w to the irradiation power 8 W, and the heat input amount is 1 from the irradiation power. 〇w's third heat loss 15 0763.doc 201117909 The summer is switched to the second heat input amount of the irradiation power of 8 w. In the present embodiment, the specific time χ is obtained for each glass layer 3 in advance, so as to control the specific time 预先 obtained in advance. The method is switched from the first heat input amount to the second heat input amount. When the glass layer of the same composition is used, the melting degree is substantially the same with respect to the same heat input amount, so if the irradiation conditions of the laser light are the same Then, the specific time X can be made substantially the same. Thereafter, the laser irradiation is performed at the irradiation power of 8 w as the second heat input amount until the return to the irradiation start position along the predetermined area of the refining, and the use of the thunder is continued. After the irradiation of the glass layer 3 by the light beam L1, the glass member 4 and the glass member 5 are welded together, whereby the glass layer 3 and its peripheral portions (the portions 4a and 5a of the glass members 4 and 5) are fused and resolidified. The glass member is welded to the glass member 5 (in the case of fusion, the glass layer 3 may be fused, and the glass members 4 and 5 may not be melted), thereby producing a glass fusion body 丨. Further, it may be necessary to treat the unstable region. Photo The laser light is superimposed by the laser light to become a stable region. By performing the control of the switching heat input amount, the glass member 4 and the glass member 5 are welded together, thereby suppressing excessive heating of the glass layer 3 and preventing it. The glass members 4 and 5 generate heat and light. Further, the glass layer 3 after the fusion is caused by the melting of the glass frit 2 to deteriorate the particle properties, and the absorption characteristics of the laser light-absorbing pigment are remarkably exhibited, and the laser light absorption is obtained. a state in which the rate is high (for example, blackening or greening under visible light). In the glass-melting method for producing the glass-melted body 1, the laser beam L1 is irradiated with a predetermined region R in the stimuli. When the glass layer 3 is melted, the glass layer 3 is melted in a direction substantially perpendicular to the traveling direction of the laser light li by irradiating the laser 150763.doc 201117909 light L1 having the first heat input amount along the predetermined region R to be melted. The heat input 1 is switched when the melting rate of the upper glass layer 3 is close to 1%, and the glass is irradiated by irradiating the laser light L1 having a second heat input amount smaller than the second heat input amount along the predetermined area of the fusion bonding. Layer 3 melts, thereby Glass member 4 and the glass member 5 welded. When the glass layer 3 is melted, if the melting rate of the glass layer 3 is close to 1%, the laser light absorption rate of the glass layer 3 will be rapidly changed, but thereafter, the irradiation has less than the first heat input amount. The laser light L1' in the second heat input can therefore suppress the glass layer 3 from being in a state of excessive heat input. By switching the heat input amount, even if the glass member 4 and the glass member 5 are welded by the irradiation of the laser light L1, the glass members 4 and 5 such as cracks in the glass members 4 and 5 can be prevented from being damaged. Therefore, according to the glass welding method, the glass members 4 and 5 can be prevented from being damaged, and the glass fused body 1 having a high degree of sin can be produced. Further, in the above-described glass splicing method, # is reduced by the irradiation power of the laser light u, and is switched from the second heat input amount to the second heat input amount. Since the amount of heat input is switched by the decrease in the irradiation power, it is possible to reliably switch from the first heat input amount to the second heat input amount. In the glass melting method, the smelting rate is close to 1 经 at a specific time x from the irradiation of the laser light U, and is switched from the W heat input amount to the second heat input amount. Therefore, it is possible to switch from the first heat input amount to the second heat input amount by controlling the method in which the previously obtained melting rate approaches (10)% of the specific time U W ^ gate. Further, in the glass layer of the same configuration, the irradiation conditions of the shots are the same in the shape of the moon, and the (10) when the shots are shot is set to be substantially (four), so that the glass layers 150763.doc 201117909 3 of the same layer can be easily formed continuously or Simultaneous melting can greatly increase the manufacturing efficiency when manufacturing a plurality of glass frits i. However, in an organic EL (electroluminescence) package or the like, since the container itself is small, the glass members 4 and 5 having a thinner thickness are used. Therefore, as the material of the glass members 4 and 5, cracks are hard to occur. And choose low-expansion glass. At this time, in order to match the linear expansion coefficient of the glass layer 3 with the linear expansion coefficient of the glass members 4 and 5 (that is, to lower the linear expansion coefficient of the glass layer 3), the glass layer 3 contains a large amount of filler containing ceramics and the like. . If the glass layer 3 contains a large amount of filler, the laser light absorption rate of the glass layer 3 will be further greatly changed before the irradiation of the laser light L1. Therefore, the above glass refining method is particularly effective in the case where low expansion glass is selected as the material of the glass members 4, 5. The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the melting rate is close to ι〇〇% when the irradiation start position A of the laser light L 经过 passes the specific time X, and the first heat input amount is switched to the second heat input amount. As shown in FIG. 9, when the intensity of the heat radiation light radiated from the glass layer 3 rises to a specific value q, the first heat input amount is switched to the second heat input amount. In this case, the heat input amount can be accurately switched by detecting the intensity of the heat radiation light having an increasing correlation with the increase in the melting rate of the glass layer 3. Further, as shown in Fig. 1A, when the intensity of the reflected light of the laser light L1 reflected by the glass layer 3 is lowered to the specific value P, the first heat input amount is switched to the second heat input amount. In this case, the intensity of the reflected light having a correlation which decreases as the melting rate of the glass layer 3 is increased can be detected, and the heat transfer can be correctly performed. Further, in the above embodiment, the amount of heat input to the glass layer 3 is controlled by changing the irradiation power of the laser light L. However, the laser light L1 may be irradiated as shown in the above formula (丨). The power is fixed, and the relative irradiation speed of the laser light L1 (that is, the traveling speed of the laser light L1 with respect to the glass layer 3) is increased to switch the heat input amount to the glass layer 3. In this case, since the amount of heat input is switched by the increase in the traveling speed of the laser light L1, it is possible to reliably switch from the first heat input amount to the second heat input amount. Further, since the traveling speed is increased and the switching is performed, the time required for welding the glass member 4 and the glass member 5 can be shortened. Further, in the case where the heat input amount is switched by increasing the traveling speed, most of the acceleration process is included. Therefore, from the viewpoint of suppressing the crystallization of the glass layer 3, it is preferable to perform the process. The switching timing (when the specific time X is elapsed, or the intensity of the heat radiation or the reflected light becomes a specific value) starts the switching control of the traveling speed, and the switching is completed when the timing of the switching is actually performed. Further, in the above embodiment, the laser beam u is caused to travel with respect to the fixed glass members 4 and 5, but the laser beam may be relatively moved with respect to the glass members* and 5, and the laser beam may be fixed to the glass. The members 4, 5 (four) or the glass members 4, 5 and the laser light L1 can also be moved. In the above-described embodiment, the heat input amount is switched when the melting rate is a specific value such as 1% by weight. However, if the glass layer 3 is appropriately melted, for example, when the melting rate is a specific value such as 9〇%, The switching of the heat input amount is performed to reliably suppress the crystallization of the glass layer 3. Furthermore, if the heat input amount is switched when the melting rate is low, the absorption rate of the laser light after switching is not charged, and there is a possibility that the melting treatment of the glass layer cannot be maintained, so that it is used for heat generation. The specific value of the melting rate of the switching of the input amount is preferably 80%. The irradiation of the laser light L1 may be performed from the side of the glass member 4 or may be performed from the opposite side of the glass member 4. Industrial Applicability According to the present invention, a highly reliable glass splicing body can be manufactured.
