METHOD AND APPARATUS FOR MANUFACTURING GFASS FAMINATE

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of Korean Patent Application No.

[0003] A glass laminate includes a substrate and glass attached to the substrate.

Generally, the glass may have a smaller area than the substrate. That is, an edge portion of the substrate may not be covered by the glass. However, recently, due to aesthetic requirements, a glass laminate in which an edge portion of a substrate is attached to glass has been required. However, due to procedural limitations, it is very difficult to attach glass that is manufactured to have precisely the same size as a substrate to the substrate. Also, it is very difficult to remove an overhang region of glass that is larger than a substrate, without generation of cracks, by using a previous glass cutting apparatus, after attaching the glass to the substrate. Thus, it has been required to develop a new method and apparatus for manufacturing a glass laminate in which both a central portion and an edge portion of a substrate are covered by the glass.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. However, embodiments of the present disclosure can be modified to various different forms and a scope of the present disclosure should not be construed as to be limited by embodiments described hereinafter. Embodiments of the present disclosure should be construed as to be provided to more fully describe the present disclosure to those having ordinary skill in the art. The same reference numerals may refer to the same elements throughout the accompanying figures. Further, various elements and regions in figures are schematically drawn. Thus, the present disclosure is not limited by a relative size or spacing drawn in the attached figures.

[0039] FIG. 1 is a cross-sectional view of a glass laminate 100 manufactured by an apparatus for manufacturing a glass laminate according to an embodiment of the present disclosure.

[0040] Referring to FIG. 1, the glass laminate 100 may include a substrate 110, an adhesive layer 130 on the substrate 110, and glass 120 on the adhesive layer 130. A main surface of the substrate 110 may be attached to the glass 120. A main surface of the substrate 110 may be completely covered by the glass 120. That is, an edge portion of the substrate 110 may be covered by the glass 120. Also, in some embodiments, at least a portion of a side wall of the glass laminate 100 may be inclined. In some embodiments, a side wall of the glass 120 may be inclined. In some embodiments, side walls of the glass 120 and the adhesive layer 130 may be inclined. In some embodiments, side walls of the glass 120, the adhesive layer 130, and the substrate 110 may be inclined. When the side wall of the substrate 110 is inclined, an inclined surface of the substrate 110 may not be attached to and covered by the glass 120 and only the main surface of the substrate 110 may be attached to and covered by the glass 120. In some embodiments, an angle 01 formed by an inclined surface of the glass laminate 100 and the main surface of the glass 120 may be about 30 degrees to about 85 degrees, and more preferably, about 45 degrees to about 80 degrees, but it is not limited thereto.

[0041] The substrate 110 may include, for example, metal, wood, an inorganic material, an organic material, or a combination thereof, but is not limited thereto. In some embodiments, the substrate 110 may further include an organic fdm coated on the metal, the wood, the inorganic material, the organic material, or the combination thereof. In other embodiments, the substrate 110 may include metal, wood, an inorganic material, an organic material, or a combination thereof that is paint-coated. In some embodiments, the substrate 110 may include a high pressure laminate (HPL), a paint-coated metal (PCM), a medium density fiberboard (MDF), or a vinyl-coated metal (VCM), but is not limited thereto. In some embodiments, the substrate 110 may include a material used for a wall panel, a backsplash, an outer packing of a cabinet or furniture, an outer packing of home appliances, a marker board, or other construction application products.

[0042] The glass 120 may include, for example, borosilicate, aluminosilicate, boroaluminosilicate, alkali-borosilicate, alkali -aluminosilicate, alkali-boroaluminosilicate, soda lime, or a combination thereof, but is not limited thereto. In some embodiments, the thickness of the glass 120 may be about 0.1 mm to about 2.0 mm. When the thickness is beyond this range, it may be difficult to manufacture the glass laminate 100 by using apparatuses 200 and 300 (refer to FIGS. 4A, 4B, 7A, and 7B) for manufacturing a glass laminate to be described below based on a method to be described below. More preferably, the thickness of the glass 120 may be about 0.15 mm to about 1.5 mm.

[0043] The adhesive layer 130 may attach the glass 120 to the substrate 110. For example, the adhesive layer 130 may include a pressure sensitive adhesive (PSA) or an optically clear adhesive (OCA), but is not limited thereto.

[0044] FIG. 2 is a flowchart of a method for manufacturing a glass laminate according to an embodiment of the present disclosure. FIGS. 3 A through 3E are cross-sectional views for describing a method for manufacturing a glass laminate, according to an embodiment of the present disclosure. [0045] Referring to FIGS. 2 and 3A, a substrate-glass overhang structure may be manufactured by attaching the glass 120, which has a larger area than the substrate 110, to the substrate 110 (SI 10). An overhang region OH protruding outwards from the substrate 110 may be located at an edge portion of the glass 120.

[0046] Referring to FIGS. 2 and 3B, a scoring operation may be performed on the overhang region OH of the glass 120 (S120). That is, a score line may be formed on the overhang region OH.

[0047] Referring to FIGS. 2 and 3C, a breaking operation may be performed on the glass 120 along the score line (S130). That is, a portion of the glass 120, which is located at a side of the score line, may be separated from a portion of the glass 120, which is located at the other side of the score line. Thus, an area of the overhang region OH may be reduced. However, a residual overhang region ROH may still remain.

[0048] Referring to FIGS. 2 and 3D, the scoring operation S120 and the breaking operation S130 may be performed on other edges of the glass 120. Thus, an area of the overhang region OH may be further reduced. However, a residual overhang region ROH may still remain.

[0049] Referring to FIGS. 2 and 3E, a finishing operation may be performed on the glass 120, the adhesive layer 130, and the substrate 110 (S140). An edge portion of the glass 120, particularly, the residual overhang region ROH may be removed by the finishing operation. For example, the edge portion of the glass 120 may be polished. In some embodiments, the glass 120 may be polished such that the edge portion of the glass 120 has an inclined side wall. In some embodiments, the adhesive layer 130 may be polished together with the glass 120. In some embodiments, the substrate 110 may be polished together with the glass 120 and the adhesive layer 130.

[0050] By using this method, the glass laminate 100 as illustrated in FIG. 1 may be manufactured.

[0051] FIGS. 4A and 4B are respectively a plan view and a side view of the apparatus

200 for manufacturing the glass laminate according to an embodiment of the present disclosure.

[0052] Referring to FIGS. 4A and 4B, the apparatus 200 for manufacturing the glass laminate may include a table 210, a guide bar 220, a scoring tool 230, and a breaking tool BT. [0053] The guide bar 220 may be placed on the table 210 and may be adjacent to a side of the table 210. The height of the guide bar 220 may be greater than 0 mm and equal to or less than about 20 mm. In some embodiments, the height of the guide bar 220 may be adjusted as indicated by an arrow Al . The height of the guide bar 220 may be adjusted to 0 mm through about 20 mm.

[0054] The scoring tool 230 may include, for example, a scoring wheel and a scoring wheel support supporting the scoring wheel. The scoring tool 230 may be movable in a direction in which the guide bar 220 extends.

[0055] The breaking tool BT may include a table extension 240, a breaking bar support 250, and a breaking bar 260. The table extension 240 may be connected to a side of the table 210. The table extension 240 may be movable in a direction getting closer to the table 210 and getting away from the table 210, as indicated by an arrow A4. That is, the distance between the table extension 240 and the table 210 may be adjusted. The apparatus 200 for manufacturing the glass laminate according to an embodiment may further include a receiver 270 located under the space between the table 210 and the table extension 240. The receiver 270 may be configured to receive glass pieces separated from the glass 120.

[0056] The breaking bar support 250 may be located on the table extension 240. The breaking bar 260 may be supported by the breaking bar support 250. As indicated by an arrow A3, the breaking bar 260 may be rotatable with respect to the breaking bar support 250. In some embodiments, the breaking bar 260 may have a cross-section having an L-shape, the cross-section perpendicular to a rotation of the breaking bar 260. However, the shape of the breaking bar 260 is not limited thereto. In some embodiments, the breaking bar 260 may extend in a direction parallel to a direction in which the guide bar 220 extends.

[0057] FIGS. 5A and 5B are respectively a plan view and a side view showing the scoring operation S120 (refer to FIG. 2) using the apparatus 200 for manufacturing the glass laminate, according to an embodiment of the present disclosure. FIG. 5C is an enlarged view of region I of FIG. 5B.

[0058] Referring to FIGS. 5 A through 5C, the table extension 240 may be set to contact the table 210. A substrate-glass overhang structure including the substrate 110, and glass 120 attached to the substrate 110 via the adhesive layer 130 and having an overhang region may be placed on the table 210. Here, the substrate-glass overhang structure may be aligned such that a side surface of the substrate 110 contacts the guide bar 220. Here, the height of the guide bar 220 may be less than or equal to the height of the substrate 110. In some embodiments, the height of the guide bar 220 may be adjusted to be less than or equal to the height of the substrate 110.

[0059] Next, the scoring tool 230 may contact a main surface of the glass 120.

Thereafter, the scoring tool 230 may be moved in a direction in which the guide bar 220 extends, as indicated by an arrow A2', to form a score line on the main surface of the glass 120.

[0060] The apparatus 200 for manufacturing the glass laminate according to an embodiment may include the guide bar 220 so that it may be easy to align the substrate-glass overhang structure. That is, the guide bar 220 may prevent the score line from straying out the overhang region.

[0061] FIGS. 6A and 6B are respectively a plan view and a side view showing the breaking operation SI 30 (refer to FIG. 2) using the apparatus 200 for manufacturing the glass laminate, according to an embodiment of the present disclosure.

[0062] Referring to FIGS. 6A and 6B, in some embodiments, as indicated by the arrow A4', the table extension 240 may be moved away from the table 210. Thus, a gap may be formed between the table extension 240 and the table 210. Thereafter, the breaking bar 260 may be rotated to apply force to the glass 120. That is, the breaking bar 260 may collide with the glass 120. Due to the collision between the glass 120 and the breaking bar 260, the glass 120 may be broken along the score line. Glass pieces separated from the substrate-glass overhang structure may be received in the receiver 270. Thus, it may be easy to collect the glass pieces.

[0063] According to the apparatus 200 for manufacturing the glass laminate according to an embodiment, the breaking operation may be performed without moving the substrate -glass overhang structure after the scoring operation. That is, it is not necessary to re-align the substrate-glass overhang structure to perform the breaking operation after the scoring operation, and thus, time may be saved, and misalignment may be prevented. Also, cracks which may occur when the substrate-glass overhang structure is moved may be prevented, and high edge quality may be achieved.

[0064] FIGS. 7A and 7B are respectively a plan view and a side view showing the finishing operation S 140 (refer to FIG. 2) using the apparatus 300 for manufacturing the glass laminate according to an embodiment of the present disclosure. [0065] Referring to FIGS. 7A and 7B, the apparatus 300 for manufacturing the glass laminate according to an embodiment may include a table 310, a polishing tool holder 322 on the table 310, and a polishing tool 321 attached to the polishing tool holder 322. The polishing tool 321 may include an abrasive for polishing the glass 120. The polishing tool 321 may include, for example, a sand paper. The polishing tool 321 may contact an edge of the glass 120, that is, a residual overhang region. The polishing tool 321 may polish the residual overhang region of the glass 120 which remains after the breaking operation. The polishing tool 321 may be inclined with respect to a main surface of the glass 120. For example, an angle 02 between the polishing tool 321 and the main surface of the glass 120 may be about 30 degrees to about 85 degrees, and more preferably, about 45 degrees to about 80 degrees. The polishing tool holder 322 and the polishing tool 321 may be movable as indicated by an arrow A5. As the polishing tool holder 322 and the polishing tool 321 move in a direction or in both directions, the residual overhang region of the glass 120 may be polished.

[0066] FIG. 8 is a side view showing an example in which an abrasive of the apparatus 300 for manufacturing the glass laminate is replaced, according to an embodiment of the present disclosure.

[0067] For example, when the glass 120 has a large area, that is, a long edge length, the abrasive of the polishing tool 321 may be consumed before the polishing is completed so that it may be necessary to replace the abrasive. To replace the abrasive, the height of the polishing tool holder 322 of the apparatus 300 for manufacturing the glass laminate according to an embodiment may be adjustable as indicated by an arrow A6. For example, to easily replace the abrasive, the polishing tool 321 may move upwards. Also, during the polishing, the abrasive may move downwards so that the polishing tool 321 may contact the glass 120. By using the apparatus 300 for manufacturing the glass laminate according to an embodiment, it is easy to replace the abrasive during finishing, even if glass having a large area is polished, and thus, the uniform edge quality throughout all of the edges of the glass 120 may be achieved, without damaging the glass 120.

[0068] FIG. 9 is a flowchart of a method for manufacturing a glass laminate by using the apparatuses 200 and 300 for manufacturing the glass laminate according to the embodiments of the present disclosure illustrated in FIGS. 4A through 6B and FIGS. 7A through 8. [0069] Referring to FIGS. 9 and FIGS. 5A through 5C, a substrate-glass overhang structure including the substrate 110, and the glass 120 attached to the substrate 110 and having an overhang region may be placed on the table 210 (SI 20).

[0070] Next, in some embodiments, the height of the guide bar 220 may be adjusted

(S220). For example, the height of the guide bar 220 may be adjusted to be less than or equal to the height of the substrate 110. FIG. 9 illustrates that the height of the guide bar 220 is adjusted after placing the substrate-glass overhang structure on the table 210 (S210) before aligning the substrate-glass overhang structure (S230). However, the height of the guide bar 220 may be adjusted (S220) before placing the substrate-glass overhang structure on the table 210 (S210) or after aligning the substrate-glass overhang structure (S230). In some embodiments, the operation S220 of adjusting the height of the guide bar 220 may be omitted.

[0071] Next, the substrate-glass overhang structure may be aligned (S230). For example, the substrate -glass overhang structure may be aligned such that a side surface of the substrate 110 contacts the guide bar 220.

[0072] Thereafter, a score line may be formed on the overhang region of the glass 120

(S240). That is, the scoring operation S120 (refer to FIG. 2) may be performed. The operation S240 of forming the score line on the overhang region of the glass 120 may include moving the scoring tool 230 in a direction in which the guide bar 220 extends.

[0073] Referring to FIGS. 9, 6A, and 6B, in some embodiments, the table extension

240 may be moved away from the table 210 (S250).

[0074] Next, the breaking bar 260 may be rotated to separate the glass 120 along the score line (S260). That is, the breaking operation S130 (refer to FIG. 2) may be performed. The glass-overhang structure may not be moved between the operation S240 of forming the score line and the operation S260 of separating the glass 120.

[0075] In some embodiments, at least one piece of the glass 120 falling between the table 210 and the table extension 240 may be received in the receiver (S270).
