Background Technology

[0004] Organic light-emitting display devices, including flat panel displays (LCDs) or curved displays, are typically manufactured using large-size mother glass during the manufacturing process.

[0005] During the manufacturing process of a display device, boxes used to hold glass are used to transport or store multiple master glass units. These boxes provide space for stacking glass, such as multiple master glass units, during the manufacturing process.

[0006] Generally, in cleanrooms used for manufacturing flat panel display devices, even with fixed air purification facilities, foreign objects floating inside the cleanroom can frequently enter the open interior space of the boxes used to hold the glass and adhere to the surface of the mother glass during transportation and storage. Therefore, quality degradation of the flat panel display device can be expected. Consequently, the interior of the boxes used to hold the glass needs to be sealed.

[0007] The aforementioned background technology refers to technical information that the inventor possesses or obtains in the process of obtaining this disclosure, and it is not necessarily considered to be known technology that is open to the public before being submitted to this disclosure. Summary of the Invention

[0052] Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings, wherein the same reference numerals always refer to the same elements. In this respect, the embodiments may take different forms and should not be construed as limited to the description set forth herein. Therefore, the embodiments are described below only by reference to the accompanying drawings to explain aspects of this description. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. Throughout this disclosure, the expression “at least one of a, b, or c” means only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or variations thereof.

[0053] Because this disclosure allows for various variations and numerous embodiments, some embodiments will be illustrated in the accompanying drawings and described in the written description. The effects and features of this disclosure, as well as methods of implementing them, will be illustrated with reference to the embodiments described in detail below with reference to the accompanying drawings. However, this disclosure is not limited to the following embodiments and can be implemented in various forms.

[0054] In the following description, embodiments of the present disclosure are described in detail with reference to the accompanying drawings. When describing with reference to the drawings, the same reference numerals are used for the same or corresponding elements, and repeated descriptions thereof are omitted.

[0055] While terms such as "first" and "second" can be used to describe various components, such components must not be limited to the terms mentioned above. The terms mentioned above are used to distinguish one component from another.

[0056] The singular forms “a,” “one,” and “the” used in this document are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0057] It will be understood that the terms “comprising” and / or “including” as used herein expressly indicate the presence of the said feature or component, but do not preclude the addition of one or more other features or components.

[0058] It will be further understood that when a layer, region, or component is referred to as being "on" another layer, region, or component, it can be directly or indirectly on that other layer, region, or component. That is, for example, intermediate layers, intermediate regions, or intermediate components can exist.

[0059] For ease of explanation, the dimensions of the elements in the accompanying drawings may be enlarged or reduced. For example, since the dimensions and thicknesses of the elements in the drawings are arbitrarily illustrated for ease of explanation, this disclosure is not limited thereto.

[0060] The x-axis, y-axis, and z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular to each other, or they can represent different directions that are not perpendicular to each other.

[0061] In cases where a particular embodiment may be implemented in different ways, a specific process sequence may be executed in an order different from the stated sequence. As an example, two processes described consecutively may be executed substantially simultaneously or in the reverse order.

[0062] In the following description, with reference to the accompanying drawings, a box for containing glass is described according to one embodiment.

[0063] Figure 1 This is a detached perspective view of a box for containing glass according to one embodiment, and Figure 2 Is with Figure 1 A perspective view of the opposite side of the separate box body used to hold the glass.

[0064] refer to Figure 1 and Figure 2 The box 10 for containing the glass may include a box body 110, an outer cover 200, and a door 300.

[0065] The box body 110 may include a plurality of frames 111 interconnected to form a box-shaped frame. In this case, at least one side of the box body 110 has an opening 112 to provide a path through which multiple pieces of glass 400, similar to the mother glass, can be transported. The frames 111 may include a metallic material with excellent strength.

[0066] Cover plate 113 is attached to the outside of frame 111. Cover plate 113 can cover the opening formed by the box frame. Cover plate 113 can be installed one after another on each surface of the box frame, or multiple covers can be installed to cover the openings formed on each surface of the box frame having multiple openings.

[0067] The cover plate 113 can be inserted into a groove formed in the frame 111, or attached to the front or back of the frame 111 by means of screws or the like. However, the attachment method is not limited to this. Except for the opening 112, the cover plate 113 completely covers the outside of the frame 111. That is, the cover plate 113 can seal every surface of the box body 110 except for the opening 112. Furthermore, the cover plate 113 can comprise a polymer resin such as polycarbonate. Additionally, the cover plate 113 can be configured to be transparent, so that the interior can be seen from the outside.

[0068] Support member 114 supporting glass 400 is installed inside the box body 110 to support it in the vertical direction (e.g., Figure 1 Each piece of glass 400 is stacked in the z-direction. The support 114 prevents the large pieces of glass 400 from sagging due to gravity and allows multiple pieces of glass 400 to be housed separately in the box body 110.

[0069] Support member 114 can be mounted from one side of box body 110 to the other, for example, horizontally mounted across the space from opening 112 in box body 110 to the surface facing opening 112. At least one support member 114 can be provided in box body 110. Support member 114 can be coupled to frame 111 of box body 110 by a separately prepared support member (not shown). Support member 114 is capable of supporting the back side of glass 400 (e.g., Figure 1 The strips in the (-z direction) of the box body 110. Multiple supports 114 can be installed in the box body 110 in the vertical direction (e.g., Figure 1 The supports 114 are spaced apart from each other in the z-direction of the box body 110. Furthermore, the multiple supports 114 can be positioned horizontally (e.g., in the z-direction) of the box body 110. Figure 1 The supports 114 are spaced apart from each other in the x-direction, and the multiple supports 114 can be arranged in the vertical direction (e.g., Figure 1 (in the z-direction) and horizontal direction (e.g., Figure 1 They are spaced apart from each other in the x-direction.

[0070] The base 115 can be respectively mounted to two opposite sides of the box body 110 facing each other. The base 115 has a hook shape protruding from the frame 111 facing the box body 110 into the interior space of the box body 110. The base 115 supports the edges on two opposite sides of the glass 400. The base 115 and the support 114 are arranged on the same horizontal line.

[0071] Therefore, when the glass 400 is loaded into the box body 110, one surface of the glass 400, such as the back side, is supported by the support 114 and the seat 115. The two opposite edges of the glass 400 are supported by the seat 115, and the middle portion of the glass 400 is supported by the support 114. Thus, each glass 400 is securely arranged within the interior space of the box body 110.

[0072] The rear stop 116 can be mounted to the surface of the box body 110 facing the opening 112. The rear stop 116 can be mounted, for example, in the vertical direction (e.g., Figure 2 One or more stripes in the z-direction of the box. A rear stop 116 is connected to the frame 111 on one side of the box body 110. The rear stop 116 is supported on one side of the glass 400 (e.g., ...). Figure 1 The edge in the y-direction.

[0073] The rear stop 116 can be used as a stop so that the glass 400 conveyed through the opening 112 of the box body 110 no longer advances beyond one side, for example, the side of the box body 110 facing the opening 112 in the internal space of the box body 110.

[0074] A pad 117 may be installed under the frame 111 (e.g., in the (-)z direction) to absorb vibrations, such as external shocks when the box body 110 moves. Alternatively, although not shown, a moving member such as a wheel may be installed in conjunction with or in place of the pad 117 to move the box body 110, the moving member being installed under the frame 111 (e.g., in the (-)z direction).

[0075] Figure 3 yes Figure 1 Perspective view of door 300 and outer cover 200, and Figure 4 This is a perspective view of a pivot according to one embodiment.

[0076] refer to Figure 3 The outer cover 200 may be disposed on at least one side of the box body 110. As an example, the outer cover 200 may be coupled to the box body 110 in which an opening 112 is formed. The outer cover 200 may have dimensions that completely cover the opening 112. In one embodiment, the outer cover 200 may be secured to the box body 110 using a pin (not shown) or by a screw connection. In this case, the contact area between the outer cover 200 and the box body 110 may be sealed.

[0077] The outer cover 200 may be included in one direction (e.g., Figure 3 Multiple openings 210 arranged side-by-side in the z-direction (in the z-direction). The openings 210 may, for example, be in the horizontal direction (…). Figure 3 The opening 210 extends from one side of the outer casing 200 to the other in the x-direction (x-direction). That is, the opening 210 can extend in the same direction as the arrangement of the glass 400 mounted in the box body 110. As an example, when the glass 400 is mounted horizontally, the opening 210 can extend horizontally. When the glass 400 is mounted vertically, the opening 210 can extend vertically. In the following description, the case where the glass 400 is mounted horizontally and the opening 210 extends horizontally is primarily described.

[0078] As described above, the opening 210 is provided to be wider than the glass 400. Figure 3 The length in the x-direction is longer to allow the glass 400 to be loaded into the box body 110. Similarly, the vertical width of the opening 210 (e.g., in the x-direction) is also longer. Figure 3 The length in the z-direction can be greater than the thickness of the glass (400). Figure 3 (Length in the z-direction).

[0079] In one embodiment, a number of openings 210 may be provided corresponding to the number of glass 400 to be loaded into the box body 110. Thus, multiple pieces of glass 400 can be inserted into the box body 110 through each opening 210. Furthermore, each opening 210 may be formed at a position corresponding to a vertical position of each support 114. Therefore, the glass 400 can be horizontally inserted through the openings 210 and seated on the support 114.

[0080] A door 300 can be arranged in the opening 210 to cover the opening 210 and can be rotatably connected to the outer casing 200. Multiple doors 300 can be provided to correspond to the number of openings 210. Because multiple doors 300 can be opened and closed individually, the openings 210 through which multiple panes of glass 400 are loaded and unloaded can be opened individually. Therefore, the inflow of external environmental particles can be prevented by reducing the open area during loading and unloading of the glass 400.

[0081] Door 300 can be opened by rotating about a pivot, such as a rotation axis, connected to door 300 and housing 200. In one embodiment, door 300 can be rotated about horizontally (e.g., Figure 3 The door 300 can rotate around a pivot extending in the vertical direction (e.g., the x-direction). In another embodiment, the door 300 can rotate about a pivot extending in the vertical direction (e.g., the x-direction). Figure 3 The pivot rotation extends in the z-direction. In the following text, the rotation of the gate 300 about a pivot extending in the horizontal direction is mainly described.

[0082] In one embodiment, pivot 310 is connected to door 300. Pivot 310 is the axis of rotation of door 300 and can pass through door 300 in the same direction as the axis of rotation. In this case, pivot 310 can pass horizontally through the upper part of door 300 (e.g., Figure 3 (The portion in the z-direction). Door 300 can be opened by rotating upward about a pivot 310, which serves as a rotation axis and passes through the upper part of door 300. Furthermore, pivot 310 can be exposed to the outside on two opposite sides of door 300. Pivot 310 can be fixedly connected to door 300 and can rotate, thereby rotating door 300 by the same angle. In this case, pivot 310 is rotatably connected to outer cover 200 and can rotate within a hole in outer cover 200 into which pivot 310 is inserted.

[0083] refer to Figure 4In one embodiment, the pivot 310 may include a recessed portion 311. Specifically, the pivot 310 may include a recessed portion 311 in each or one of the two opposite ends of the pivot 310. The rotating pin 510 of the actuator 500, which will be described below, can be fitted into the recessed portion 311. The shape of the recessed portion 311 may be a polygon such as a quadrilateral, and may be formed into an angular shape such as a star to enhance the connection force with the actuator 500. Hereinafter, the recessed portion 311 is mainly described as being formed as... Figure 4 The quadrilateral shape shown.

[0084] Figure 5 yes Figure 3 A sectional view of the door 300 and the outer cover 200 taken along line VV. Figure 6 yes Figure 5 An enlarged view of region A in the image, and Figure 7 yes Figure 6 The view of door 300 when it is opened.

[0085] refer to Figure 5 and Figure 6 The two opposite sides of door 300 can be in one direction (e.g., Figure 5 The door 300 contacts the outer cover 200 in the z-direction. That is, because the door 300 blocks the opening 210, the door 300 can contact two opposite sides of the opening 210, for example, the upper and lower parts of the opening 210. The first side 321 represents the side of the door 300 adjacent to the pivot 310, and the second side 322 represents the side of the door 300 facing the first side 321, that is, in the height direction of the door 300 (e.g., in the z-direction), the door 300 contacts the outer cover 200. Figure 5 On the other side separated from pivot 310 in the z direction.

[0086] In one embodiment, the first side 321 of the door 300 may include a curved surface. As an example, the transverse cross-section of the first side 321 may have, for example, a curved surface. Figure 6 The diagram shows a convex semicircular arc centered on the axis of rotation or pivot 310. Although the transverse sectional view of the first side 321 is not limited to this, for ease of description, the case where the transverse section of the first side 321 has a semicircular arc will be described in the following text.

[0087] The outer cover 200 that contacts the first side 321, i.e., the inner surface of the opening 210, may include a curved portion 211 and a flat portion 212. To accommodate a portion of the curved surface of the first side 321, the curved portion 211 may be formed in a shape corresponding to the outer surface of the first side 321. As an example, the transverse cross-section of the curved portion 211 may have, for example, a shape similar to... Figure 6 The quarter-circular portion shown. In addition, a curved portion 211 may be formed on the side of the opening 210 facing the box body 110.

[0088] The flat portion 212 can be connected to the curved portion 211 and is formed on the side of the opening 210 facing the outside of the box body 110.

[0089] Therefore, when the door 300 rotates, the curved portion 211 can accommodate the curved surface of the door 300. Furthermore, because the curvature of the curved surface of the door 300 is the same as the curvature of the curved portion 211 of the outer cover 200, the door 300 can rotate smoothly in the opening 210.

[0090] Furthermore, the planar portion 212 can restrict the rotation of the door 300. For example... Figure 7 As shown, when the door 300 is opened, its rotation is stopped by the planar portion 212 of the outer cover 200. When one side of the door 300 contacts the planar portion 212 of the outer cover 200, the door 300 is blocked by the planar portion 212 and cannot rotate. As described above, the planar portion 212 prevents the door 300 from being over-opened, and thus prevents foreign objects from being introduced into the box body 110. In one embodiment, Figure 7 The diagram shows the planar portion 212 in the horizontal direction (e.g., Figure 7 The door 300 has a plane in the (-y) direction. In this case, the door 300 can rotate approximately 90° to open fully. However, the construction of the door 300 is not limited to this; the plane portion 212 can be arranged in the plane formed by the (-y) direction and the z direction, allowing the door 300 to rotate further than approximately 90° to open fully. Therefore, the rotation range of the door 300 can be limited by a simple method.

[0091] The door 300 can be opened by rotating the door 300 so that the outer side of the door 300 contacts the flat portion 212 of the outer cover 200, and the door 300 can be closed by rotating the door 300 so that the second side 322 of the door 300 contacts the outer cover 200, especially the side of the opening 210.

[0092] In one embodiment, the second side 322 may have a slope. In this case, the opening 210 that contacts the slope of the door 300 may also include a slope corresponding to the slope of the second side 322. The slope of the second side 322 can close the door 300 by contacting the slope of the opening 210.

[0093] In one embodiment, such as Figure 6 As shown, the included angle between the second side 322 of the door 300 and its outer surface (the side surface facing the outside of the box body 110), and the included angle between the inner side of the outer cover 200 and the inclined portion (e.g., the ramp) of the outer cover 200, can have the same angle θ. That is, the surface of the door 300 facing the outside of the box body 110 can be larger than the surface of the door 300 facing the inside of the box body 110. As an example, such as Figure 6As shown, when the door 300 rotates about its upper part, the inclined surface of the door 300 can have an upward slope from the outer surface to the inner surface. Therefore, the door 300 cannot rotate toward the inside of the box body 110 because the inclined portion of the outer cover 200 prevents the door 300 from rotating toward the inside of the box body 110, and the door 300 can only rotate toward the outside of the box body 110 to be opened. This effectively prevents foreign objects from being introduced into the box body 110.

[0094] In addition, the airflow around the box 10 is usually guided from top to bottom, and since the slope of the door 300 has an upward slope from the outer surface to the inner surface, it can better suppress the inflow of foreign objects.

[0095] In one embodiment, for more effective sealing, a sealing member may be arranged on the contact surface between the second side 322 and the inclined portion of the outer casing 200. As an example, the sealing member may be a sealant comprising rubber.

[0096] Figure 8 This is a perspective view of a door 300 and a driver 500 according to one embodiment. Figure 9 This is a perspective view of a driver 500 according to one embodiment.

[0097] refer to Figure 8 The housing 10 may further include an actuator 500. The actuator 500 provides power for rotating the door 300. The actuator 500 may be arranged on one side or both opposite sides of the housing 200 and is coupled to the door 300. Given the large size of the housing 10 and therefore the heavy weight of the door 300, it may be difficult to rotate the door 300 using only the torque transmitted by the actuator 500 arranged on one side of the housing 200. That is, depending on the torque required to open and close the door 300, the actuator 500 may be arranged on only one side or both opposite sides of the housing 200. In the following description, for convenience, the actuator 500 arranged on one side of the housing 200 will be described primarily.

[0098] In one embodiment, the drive 500 may include a rotating pin 510. The rotating pin 510 is a component connected to a rotating mechanism, such as a motor, for rotating the door 300.

[0099] A rotating pin 510 can be connected to a recessed portion 311 of the pivot 310. Specifically, the shape of the rotating pin 510 can be formed to correspond to the shape of the recessed portion 311. The rotating pin 510 of the actuator 500 can be fitted into the recessed portion 311 of the pivot 310. Therefore, when the rotating pin 510 rotates, the pivot 310 rotates, and thus, the door 300, which is fixedly connected to the pivot 310, can rotate about the pivot 310.

[0100] Furthermore, the number of rotating pins 510 in the actuator 500 can be the same as the number of doors 300 to control the opening of each door 300. In this case, multiple rotating pins 510 can rotate individually to open and close each door 300, or rotate simultaneously to open and close all doors 300. For this purpose, an operating button 520 can be provided to the actuator 500. When the operating button 520 is turned on and off, the rotating pins 510 can rotate and stop. This controls the rotation of the doors 300.

[0101] like Figure 8 As shown, the driver 500 may not always be connected to the door 300. As an example, the driver 500 may remain disconnected from the door 300 and may be connected to the door 300 when the door 300 needs to be opened and closed.

[0102] Figure 10 This is a cross-sectional view of a modified embodiment of the door and housing according to one embodiment. Figure 11 for Figure 10 A cross-sectional view of the door when it is open. This embodiment is a modified embodiment of the above embodiment. Descriptions identical to those in the above embodiment are omitted; the differences are mainly described below.

[0103] refer to Figure 10 Door 300 may be arranged in opening 210 to cover opening 210 and connected to outer cover 200. In this case, pivot 310 may pass horizontally through the lower part of door 300 (e.g., Figure 10 (in the z direction). The door 300 can be opened by rotating the door 300 downward using the pivot 310 passing through the lower part as the axis of rotation.

[0104] In one embodiment, the first side 321 may be arranged at the lower part of the door 300, and the second side 322 may be arranged at the upper part of the door 300. That is, as Figure 10 As shown, door 300 and opening 210 can be Figure 6 The door 300 and opening 210 are vertically inverted shapes.

[0105] In this case, such as Figure 10 As shown, the angle between the second side 322 of the door 300 and its outer surface (the side surface facing the outside of the box body 110), and the angle between the inner side of the outer cover 200 and the inclined portion of the outer cover 200, can have the same angle θ. That is, the surface of the door 300 facing the outside of the box body 110 can be larger than the surface of the door 300 facing the inside of the box body 110. As an example, such as... Figure 10As shown, when the door 300 rotates around its lower part, the inclined surface of the door 300 can have a downward slope from the outer surface to the inner surface. Therefore, because the inclined portion of the outer cover 200 prevents the door 300 from rotating toward the inside of the box body 110, the door 300 can only rotate toward the outside of the box body 110 to be opened.

[0106] In this embodiment, as described above, the door 300 can expose the opening 210 by rotating a rotation axis arranged adjacent to the lower part of the opening 210. Therefore, the glass can be loaded into the box body 110 through the opening 210 in the upper part of the opened door 300.

[0107] Figure 12 This is a cross-sectional view of the door and outer casing of a box according to another embodiment. Figure 13 yes Figure 12 The door and outer casing are shown in a cross-sectional view taken along line XIII-XIII. The following description primarily focuses on the differences from the embodiments described above.

[0108] refer to Figure 12 and Figure 13 The outer cover 200 may be arranged on at least one side of the box body 110. As an example, the outer cover 200 may be attached to the box body 110 in which the opening 112 is formed.

[0109] The outer cover 200 can form a frame with an outer perimeter and include an opening 210 in the center. The opening 210 can be an opening that allows multiple pieces of glass 400 to enter into and exit from the box 10.

[0110] Door 300 can be connected to outer cover 200 to cover opening 210. Specifically, door 300 may include multiple door bodies 350. The multiple door bodies 350 may be in one direction, for example, with respect to the stacking direction of glass 400 in box body 110 (i.e., Figure 12 The doors 350 are arranged side-by-side in the same direction (z-direction) and connected to each other. In one embodiment, the multiple doors 350 can be connected to each other in a manner that they are assembled to adjacent doors 350. Specifically, as shown in... Figure 13 As shown, multiple door bodies 350 can be connected to each other in such a way that, starting with the door body 350 fixed to the lower part of the outer cover 200, the door bodies 350 arranged adjacent to each other are assembled sequentially.

[0111] In one embodiment, each door 350 may have a width in one direction (e.g., Figure 12 The shape narrows in the z-direction. Therefore, the door body 350 to be assembled cannot be completely separated from the already assembled door body 350.

[0112] In another embodiment, each door 350 may have a constant width. In this case, to prevent the door 350 from detaching from the door 350 adjacent to it, a hook member, such as a stop, may be provided on the upper part of the door 350 to be assembled. Hereinafter, the case where each door 350 is formed in a tapered shape will be primarily described.

[0113] Figure 14 This is a perspective view of the protrusion 220 and guide rail 230 according to one embodiment.

[0114] Reference Figures 12 to 14 The outer cover 200 may include protrusions 220 and guide rails 230.

[0115] Protrusions 220 protrude from two opposite sides of the outer cover 200 toward the door 300. In this case, the protrusions 220 can be attached to the door 300, specifically, one of a plurality of door bodies 350. Figure 12 In one embodiment, a protrusion 220 is shown attached to the lowest portion of a plurality of door bodies 350.

[0116] The protrusion 220 can be arranged in the direction of multiple door bodies 350, for example Figure 12 The protrusion 220 moves vertically along guide rail 230 as described below. For this purpose, an actuator may be provided to the housing 200 to move the protrusion 220 vertically. Alternatively, the drive 500 may include an actuator and be coupled to the lower part of the housing 200 to raise the protrusion 220 only when the door 300 needs to be opened.

[0117] Figure 15 yes Figure 12 A perspective view of the door 300 and the outer cover 200 along line XV-XV.

[0118] Reference Figures 12 to 15 The guide rail 230 can be formed on two opposite sides of the outer cover 200. Figure 12 On one side in the x-direction and on the other side in the -x-direction. The guide rail 230 may include a groove. The door 300 may be accommodated in the groove. Therefore, the door 300 and the protrusion 220 attached thereto can slide along the guide rail 230.

[0119] Figure 16 yes Figure 12 A cross-sectional view of door 300 when it is opened. Figure 17 yes Figure 16 A sectional view taken along line XVII-XVII of door 300.

[0120] refer to Figure 16 and Figure 17As the protrusion 220 moves upward along the guide rail 230, the door 300 opens. Specifically, as the protrusion 220 moves upward, the lowermost door body 350 connected to the protrusion 220 can move upward into the interior of an adjacent door body 350, and the protrusion 220 can continuously push the next door body 350 upward. Multiple door bodies 350 can continuously move upward into the interior of adjacent bodies, and thus, the door 300 can be opened. In this case, each of the multiple door bodies 350 may include a receiving groove 351 for receiving the protrusion 220 when it moves upward.

[0121] Figure 18 This is a view showing a method of manufacturing a cover window according to one embodiment.

[0122] refer to Figure 18 Glass 400 can be loaded into box 10 to house the glass. In this case, box 10 for housing the glass can be the same as the one described above. Glass 400 can be, for example, ultra-thin glass with a thickness of 1 mm or less. Glass 400 can be loaded into box 10 through doors 300. In this case, multiple doors 300 can be opened one after another, and glass 400 can also be loaded one after another. Furthermore, multiple doors 300 can be opened when actuator 500 is temporarily engaged and torque is transmitted. In one embodiment, glass 400 can be loaded into box 10 for housing the glass by a robotic arm. Therefore, the opening area of ​​doors 300 can be reduced, and thus the inflow of external foreign objects can be reduced. Furthermore, because doors 300 rotate outward to be opened, foreign objects will not be introduced into the interior of box 10 for housing the glass.

[0123] After all the glass 400 has been loaded, the box 10 for holding the glass can be moved to the cover glass manufacturing table 40 by a moving device. In this case, the box 10 for holding the glass can be sealed with all doors 300 closed. In one embodiment, the cover glass manufacturing table 40 can be carried out in a clean room where a clean environment is maintained.

[0124] In one embodiment, the box 10 for holding glass, which is moved to the cover window manufacturing table 40, can dock with the cover window manufacturing table 40. Next, the door 300 can be opened according to the above description, and the glass 400 loaded inside the box 10 can be transferred to the cover window manufacturing table 40. In this case, similar to the case of loading glass 400, the doors 300 can be opened one after another, and the glass 400 loaded in the box 10 can be moved to the cover window manufacturing table 40 one after another. However, in another embodiment, it should be understood that multiple doors 300 can be opened, and multiple pieces of glass 400 can be transferred to the cover window manufacturing table 40 simultaneously.

[0125] In one embodiment, a protective coating can be formed on the glass 400 transferred to the cover glass manufacturing table 40. The protective coating can be formed using ultraviolet (UV) curing ink.

[0126] Subsequently, the glass 400 can be cut to a size suitable for the display device. Furthermore, the glass 400 can be polished and chemically strengthened to protect it from impacts or scratches. In one embodiment, the chemical strengthening process may include immersing the glass 400 in a chemical solution. By replacing sodium ions on the surface of the glass 400 with potassium ions, the glass 400 can have more impact-resistant physical properties.

[0127] The glass 400 processed using the above-described method can be used to manufacture cover windows. Furthermore, in the case of flexible cover windows, a portion of the glass 400 can be further bent using a thermoforming process.

[0128] The box for holding glass, according to an embodiment, can be easily opened and closed, while preventing foreign matter from flowing in by sealing its interior.

[0129] The method for loading glass into a box according to the embodiment can easily load glass while preventing foreign objects from being introduced into the box.

[0130] The method for manufacturing a cover window according to the embodiment can easily manufacture a cover window with excellent quality by using a box.
