The glass plate assembly 100 may include a bottom plate 110, a flexible magnet 120, and a guiding part 130.

The bottom plate 110 may include a first surface 110F1 and a second surface 110F2 opposite to each other. The bottom plate 110 may include a plurality of slots 110H extending from the first surface 110F1 to the second surface 110F2 and passing through the bottom plate 110. The slot 110H is a space defined by the sidewall 110S extending from the first surface 110F1 of the bottom plate 110 to the second surface 110F2. The laser beam and the blowing air can pass through the slot 110H, and the slot 110H can overlap the glass The target cutting lines on the ply 160 overlap vertically.

In an exemplary embodiment, the bottom plate 110 may be made of, for example, metal, wood, inorganic material, organic material, or a combination thereof, but the present disclosure is not limited thereto. For example, the bottom plate 110 may include aluminum, copper, iron, nickel, or a combination thereof. In order to ensure mechanical stability when the glass laminate 160 is mounted on the bottom plate 110 and the laser beam and the blowing air are supplied to the bottom plate 110 and the glass laminate 160, the bottom plate 110 may include a sufficiently stable material. The bottom plate 110 may be heavy enough not to vibrate or move when the purge air is supplied, and light enough to allow easy operation when repeatedly loaded on and unloaded from the loading table 30. For example, the bottom plate 110 may have a thickness t11 of about 2 mm to about 100 mm (see FIG. 3), but the present disclosure is not limited thereto.

The flexible magnet 120 may be disposed on the first surface 110F1 of the bottom plate 110. Although not shown, the flexible magnet 120 can be attached to the first surface 110F1 of the bottom plate 110 by using an adhesive layer (not shown). The flexible magnet 120 may include a plurality of openings 120H, and the opening 120H of the flexible magnet 120 may communicate with the slot 110H of the bottom plate 110 accordingly. For example, during the laser cutting of the glass laminate 160, the laser beam and the blowing air can pass through the opening 120H of the flexible magnet 120 and the slot 110H of the bottom plate 110.

In an exemplary embodiment, the flexible magnet 120 may have a magnetic flux density of about 100 Gauss to about 3,000 Gauss. Therefore, when the glass laminate 160 is mounted on the flexible magnet 120, the glass laminate 160 can be fixed to the flexible magnet 120 by magnetic force. In an exemplary embodiment, the flexible magnet 120 may have a thickness t12 of about 0.1 mm to about 20 mm (see FIG. 3), but the present disclosure is not limited thereto.

The guide part 130 may be disposed on the first surface 110F1 of the bottom plate 110 on one side of the flexible magnet 120 and extend in the first direction (D1 direction). Here, the first direction (D1 direction) means a direction parallel to an edge of the first surface 110F1 of the bottom plate 110. As shown in FIG. 1, the guide portion 130 may only be disposed on the edge of the bottom plate 110. In another embodiment, the guide part 130 may be disposed on at least two edges of the bottom plate 110. The guide portion 130 and the bottom plate 110 may be integrally formed, but the present disclosure is not limited thereto.

Relative to the first surface 110F1 of the bottom plate 110, in the third direction (D3 direction) perpendicular to the first surface 110F1, the upper surface of the guide portion 130 may be at a higher level than the upper surface 120U of the flexible magnet 120 . When the glass laminate 160 is installed on the glass plate assembly 100, the lateral surface of the glass laminate 160 may contact the guide portion 130. Therefore, the guide part 130 can precisely adjust the installation position of the glass laminate 160, and the ease of operation can be enhanced by the guide part 130 during the installation process of the glass laminate 160.

As shown in Figure 2, the slots 110H (and corresponding openings 120H communicating with the slots 110H) may be spaced parallel to each other at the same distance in the first direction (D1 direction). In a plan view, the width w11 of each slot 110H in the second direction (D2 direction) may range from about 2 mm to about 20 mm. The width w11 of each slot 110H in the second direction (D2 direction) may be based on the size of the glass laminate section 160P (see FIG. 10) to be cut, the material of the glass laminate 160, the laser beam The power, the pressure of the purge air, and the like are appropriately selected. For example, when the width w11 of each slot 110H is less than about 2 mm, metal melts, fragments, or burrs of the glass laminate 160 become attached to the inside of the slot 110H, and thus may block the slot 110H , Or the width w11 of each slot 110H is smaller than the diameter of the purge air flow injected onto the glass laminate 160 so that improper movement or vibration of the glass laminate 160 occurs. When the width w11 of each slot 110H is greater than about 20 mm, the area of the portion of the glass laminate 160 that is not supported by the glass plate assembly 100 increases, and therefore, it may be caused by laser beam irradiation or blowing air injection Improper movement or vibration of the glass laminate 160 occurs.

In a plan view, the first distance d11 between two adjacent slots 110H of the plurality of slots 110H may be determined according to the target size of the glass laminate section 160P (see FIG. 10) to be cut. For example, when producing a rectangular or bar-shaped glass laminate section 160P with a horizontal width greater than a vertical width, the first distance d11 between the slots 110H may correspond to the vertical of the desired glass laminate section 160P width. That is, the first distance d11 between the slots 110H and the number of the slots 110H can be determined according to the target vertical width of the glass laminate section 160P.

As shown in FIG. 4, the glass laminate 160 may include a metal thin plate 162, an adhesive layer 164, and a glass layer 166. The adhesive layer 164 may be arranged between the glass layer 166 and the metal thin plate 162 such that the bottom surface of the glass layer 166 faces the upper surface of the metal thin plate 162. The glass laminate 160 may include a first major surface 160F1 and a second major surface 160F2 opposite to each other. The first major surface 160F1 of the glass laminate 160 corresponds to the upper surface of the glass layer 166 opposite to the bottom surface of the glass layer 166 , And the second main surface 160F2 of the glass laminate 160 may correspond to the bottom surface of the metal thin plate 162 opposite to the upper surface of the metal thin plate 162. In other embodiments, the adhesive layer 164 may be omitted, and the glass layer 166 may be directly adhered to the thin metal plate 162.

The thin metal plate 162 may include steel, stainless steel, nickel, cobalt, or a metal alloy including at least one of them. The thin metal plate 162 may include a ferromagnetic material, and thus the thin metal plate 162 may be fixed to the flexible magnet 120 by magnetic force. In an exemplary embodiment, the metal thin plate 162 may have a thickness t21 of about 0.1 mm to about 5 mm. More specifically, the thickness t21 of the metal thin plate 162 may be between about 0.2 mm and about 3 mm.

The glass layer 166 may be formed of glass, ceramic, glass-ceramic, or a combination thereof. The glass layer 166 may include, for example, borosilicate, aluminosilicate, boroaluminosilicate, alkali metal borosilicate, alkali metal aluminosilicate, alkali metal boroaluminosilicate, soda lime, or a combination thereof , But this disclosure is not limited to this. For example, the glass layer 166 may be a commercially available flexible glass under the product name of Corning® Willow® glass (Corning Incorporated, Corning, New York, USA) or a commercially available flexible glass in Corning® Gorilla® glass (Corning Incorporated, Corning, New York, USA). , USA) commercially available chemically strengthened glass under the product name. For example, the glass layer 166 may be formed using a molding process, such as a down-drawing process such as a fusion-drawing process or a slot-drawing process, a float process, a pull-up process, or a rolling process. In an exemplary embodiment, the glass layer 166 may have a thickness t22 of about 0.1 mm to about 2.0 mm. More specifically, the thickness t22 of the glass layer 166 may be between about 0.15 mm and about 1.5 mm.

The adhesive layer 164 may connect the glass layer 166 to the metal sheet 162, and may be formed of, for example, a pressure sensitive adhesive (PSA) or an optically clear adhesive (OCA), but the present disclosure is not limited to this.

Since the thin metal plate 162 is exposed through the second main surface 160F2 of the glass laminated plate 160, when the glass laminated plate 160 is mounted on the glass plate assembly 100, the thin metal plate 162 can be placed on top of the flexible magnet 120. The surface 120U is in contact. In this regard, the thin metal plate 162 can be firmly fixed on the flexible magnet 120 by magnetic force. In addition, when the cutting process of the glass laminate 160 is performed by irradiating the laser beam in the direction in which the slot 110H extends and supplying purge air, the glass laminate 160 that has been cut and separated from the glass laminate 160 The section 160P (see FIG. 10) can be fixed and held on the upper surface 120U of the flexible magnet 120 by magnetic force. Therefore, the occurrence of cutting unevenness or cutting defects can be prevented during the cutting process of the glass laminated plate 160, and the glass laminated plate section 160P can exhibit excellent cutting cross-sectional quality.

Fig. 5 shows a cross-sectional view of a glass plate assembly 100A according to other exemplary embodiments. Fig. 5 is a cross-sectional view taken along the line III-III' of Fig. 2.

Referring to FIG. 5, the bottom plate 110A may include a plurality of side walls 110SA defining a plurality of slots 110HA, and each side wall 110SA may include a step portion 112. Each slot 110HA may extend in the lateral direction by the step portion 112 in an area adjacent to the second surface 110F2 of the bottom plate 110A. For example, each slot 110HA may have a first width w11a at the same level as the first surface 110F1 of the bottom plate 110A, and may have a first width w11a greater than the first width w11a at the same level as the second surface 110F2 of the bottom plate 110A. Two width w12a. The first width w11a of each slot 110HA in the second direction (D2 direction) may range from about 2 mm to about 20 mm, and the first width w11a of each slot 110HA in the second direction (D2 direction) The second width w12a may be in the range of about 3 mm to about 40 mm.

According to the above-mentioned embodiment, since the second width w12a of each slot 110HA is greater than the first width w11a, the metal melt, fragments, or metal melt generated in the portion irradiated by the laser beam during the cutting process of the glass laminate 160 The burr may not be attached to the side wall of the slot 110HA or may not block the slot 110HA, and can be easily transferred to the suction hole 30H of the loading table 30 by blowing air.

Fig. 6 is a cross-sectional view showing a glass plate assembly according to other exemplary embodiments; Fig. 6 is a cross-sectional view taken along the line III-III' of Fig. 2.

Referring to FIG. 6, the bottom plate 110B may include a plurality of slots 110HB, and each slot 110HB may include a pair of side walls 110SB that are inclined and extend in the first direction (D1 direction). The pair of side walls 110SB may be inclined at opposite inclination angles relative to the first surface 110F1 of the bottom plate 110B. For example, due to the pair of side walls 110SB inclined at mutually opposite inclination angles, each slot 110HB may extend in the lateral direction in an area adjacent to the second surface 110F2 of the bottom plate 110B. For example, each slot 110HB may have a first width w11b at the same level as the first surface 110F1 of the bottom plate 110B, and may have a first width w11b greater than the first width w11b at the same level as the second surface 110F2 of the bottom plate 110B. Two width w12b. The first width w11b of each slot 110HB in the second direction (D2 direction) may range from about 2 mm to about 20 mm, and the first width w11b of each slot 110HB in the second direction (D2 direction) The second width w12b may be in the range of about 3 mm to about 40 mm.

According to the above-mentioned embodiment, since the second width w12b of each slot 110HB is greater than the first width w11b, the metal melt, fragments, or metal melt generated in the portion irradiated by the laser beam during the cutting process of the glass laminate 160 The burr may not be attached to the side wall of the slot 110HB or may not block the slot 110HB, and can be easily transferred to the suction hole 30H of the loading table 30 by blowing air.

Fig. 7 is a plan view showing a glass plate assembly according to other exemplary embodiments; Figs. 8A and 8B are cross-sectional views taken along the line XIII-XIII' of Fig. 7.

Referring to FIG. 7, FIG. 8A, and FIG. 8B, the bottom plate 110C may include a pair of first slots 110HC1 and a pair of second slots 110HC2. The pair of first slots 110HC1 may extend in parallel in the first direction (D1 direction), and the pair of second slots 110HC2 may extend in parallel in the second direction (D2 direction). Each of the pair of second slots 110HC2 and each of the pair of first slots 110HC1 may intersect at the intersection area 110HX.

Because the pair of second slots 110HC2 intersect the pair of first slots 110HC1, the glass plate assembly 100C may include a central portion 100C1 and an outer circumferential portion 100C2. For example, when viewed in a plan view, the central portion 100C1 can be surrounded by the pair of first slots 110HC1 and the pair of second slots 110HC2, and the outer circumferential portion 100C2 can surround the pair of first slots 110HC1 and the pair of slots 110HC1. Position the central part 100C1 between the second slots 110HC2. For example, the outer circumferential portion 100C2 may include the guide portion 130 and the outermost edge of the bottom plate 110C. The central portion 100C1 may be spaced apart from the outer circumferential portion 100C2, and the pair of first slots 110HC1 and the pair of second slots 110HC2 may be defined between the central portion 100C1 and the outer circumferential portion 100C2.

In an exemplary embodiment, as shown in FIG. 8A, the central portion 100C1 and the outer circumferential portion 100C2 may be separated from each other and be independently loaded onto or unloaded from the loading platform 30. In this regard, the separation distance w21 in the second direction (D2 direction) between the central portion 100C1 and the outer circumferential portion 100C2 (or the width of the pair of first slots 110HC1 in the second direction (D2 direction) ) Can be in the range of about 2 mm to about 20 mm.

In other embodiments, as shown in Figure 8B, the central portion 100C1 may be connected to the outer circumferential portion via a metal bridge 140 attached to the bottom surface of the glass plate assembly 100C (or the second surface 110F2 of the bottom plate 110C) 100C2.

A method for producing a glass laminate by using the apparatus 1 for producing a glass laminate including the glass plate assembly 100, 100A, 100B, or 100C according to the exemplary embodiment shown in FIG. 1 to FIG. 8B Refer to Figure 9 and Figure 10 for description. For example, the method of producing the glass laminate may be a method of forming the glass laminate section 160P by cutting the glass laminate 160 using the apparatus 1. In Fig. 10, a method of producing a glass laminate by using the glass plate assembly 100A is shown.

First, the glass plate assembly 100A including the bottom plate 110A including at least one slot 110HA, the flexible magnet 120, and the guide portion 130 may be placed on the loading platform 30 (operation S210).

In an exemplary embodiment, the glass plate assembly 100A may be installed on the loading table 30 so that at least one slot 110HA of the glass plate assembly 100A and the plurality of suction holes 30H of the loading table 30 vertically overlap. For example, the glass plate assembly 100A may be installed on the loading table 30 so that the upper surface of the loading table 30 is not exposed by the at least one slot 110HA. When the upper surface of the loading table 30 is exposed by the at least one slot 110HA, the laser beam irradiated to the glass plate assembly 100A in the subsequent process may partially damage the loading table 30.

Subsequently, the glass laminate 160 may be placed on the glass plate assembly 100A so that the edge 160E of the glass laminate 160 is in contact with the guide portion 130 and fixed to the flexible magnet 120 by magnetic force (operation S220).

In an exemplary embodiment, as described above with reference to FIG. 4, the glass laminate 160 may have a plate-shaped structure, in which the metal thin plate 162 and the glass layer 166 are attached to each other by the adhesive layer 164. The metal thin plate 162 of the glass laminate 160 may include steel, stainless steel, nickel, cobalt, or a metal alloy including at least one of them, and therefore, the metal thin plate 162 may be firmly attached to the flexible magnet by magnetic force 120.

In an exemplary embodiment, the guide portion 130 extends in the first direction (D1 direction) on the first surface 110F1 of the bottom plate 110A, and the upper surface of the guide portion 130 is higher than the upper surface of the flexible magnet 120. Level. Therefore, in the process of mounting the glass laminate 160 on the glass plate assembly 100A so that the edge 160E of the glass laminate 160 is in contact with the guide portion 130, misalignment of the glass laminate 160 or the like can be prevented.

Subsequently, the laser beam may be irradiated in the direction in which the at least one slot 110HA extends, thereby cutting the glass laminate 160 (operation S230).

In an exemplary embodiment, the laser beam irradiation unit 10 (see Figure 1) can be connected to the position movement control unit 20 (see Figure 1), and can be configured to follow a predetermined target of the glass laminate 160 The cutting line (not shown) moves. The laser beam irradiation unit 10 may include a laser irradiation part 12 (refer to FIG. 1) and a purge air supply part 14.

In an exemplary embodiment, the laser beam may be emitted from the laser irradiation part 12 to the target cutting position of the glass laminate 160 so that at least a part of the glass laminate 160, such as the metal thin plate 162, may be melted. For example, the heat generated by the laser beam can be locally concentrated on the target cutting position of the glass laminate 160 that has been irradiated with the laser beam, and therefore, the thin metal plate 162 can be melted and cut. In addition, during the re-cooling of the target cutting position of the glass laminate 160, stress may be locally generated in the glass layer 166, and therefore, the glass layer 166 may be cut by the transmission or diffusion of the generated stress.

Subsequently, purge air may be supplied to the glass laminate 160 so as to transfer the fragments 168R of the cut glass laminate 160 to the suction holes 30H of the loading table 30 (operation S240).

In an exemplary embodiment, the purge air may be injected from the purge air supply part 14 of the laser beam irradiation unit 10 into the suction hole 30H. The purge air flow is schematically shown by the dotted arrow in Figure 10.

In an exemplary embodiment, the purge air supply operation may be performed after the laser beam irradiation operation. In other embodiments, the laser irradiation part 12 may continuously emit the laser beam onto the glass laminate 160 while continuously moving along the target cutting line, and the purge air supply part 14 may be in the laser irradiation part 12 After that, while continuously moving along the target cutting line, purge air is injected into the part where the laser beam irradiates the glass laminate 160.

In the purge air supply operation, the portion of the glass laminate 160 that has been irradiated with the laser beam may be cooled to locally generate stress in the glass layer 166, thereby inducing or facilitating the cutting of the glass layer 166. In addition, the fragments 168R of the cut glass laminate 160 (or the metal melt or burrs of the glass laminate 160) by the purge air supply operation can be transferred to the suction hole 30H. Since the glass laminate 160 is firmly attached to the glass plate assembly 100A by magnetic force, improper movement or vibration of the glass laminate 160 can be prevented even when the purge air is injected under a relatively high pressure.

The above-mentioned operations may be performed to thereby complete the production of the glass laminate section 160P from the glass laminate 160. In the case of cutting the glass laminate 160 into a plurality of glass laminate sections 160P, the cut glass laminate section 160P is held on the glass plate assembly 100A in a state of being fixed to it by magnetic force Therefore, the movement or vibration of the glass laminate section 160P due to the injection of the purge air can be prevented.

Subsequently, the glass laminate section 160P may be unloaded, and another glass laminate 160 may be placed on the glass plate assembly 100A and the cutting process may be repeatedly performed thereon (that is, operations S220 to S240 may be repeated carried out). Therefore, the glass plate assembly 100A can be reused, which is economical.

According to the above production method, because the glass laminate 160 is firmly and temporarily fixed to the glass plate assembly 100A by the magnetic force of the flexible magnet 120, the glass laminate 160 cannot move or vibrate, even under laser irradiation. After that, the same is true when injecting purge air under relatively high pressure. Therefore, it is possible to prevent the occurrence of deviation of the cutting position of the glass laminate 160, cutting defects, or the like. In addition, because the glass laminate 160 can be cut by continuously performing the laser irradiation operation and the blowing air supply operation, the glass laminate section 160P may have excellent cutting cross-sectional quality.
