[0052] The embodiments of this utility model are provided to illustrate the utility model more completely to those skilled in the art. The following embodiments can be modified into various other forms, and the scope of this utility model is not limited to the following embodiments.

[0053] In the following description, for ease of explanation, some embodiments of the present invention are illustrated with reference to the accompanying drawings. When labeling the constituent elements of the drawings, the same reference numerals are used as much as possible for the same constituent elements, even if they are shown in other drawings.

[0054] The terms or words used in this specification and claims should not be limited to their ordinary or dictionary meanings. In order to describe their utility model in the best possible way, the inventor must interpret them in accordance with the principle that the terms and concepts can be appropriately defined, to mean and represent the technical concept of this utility model.

[0055] The terminology used in this specification is for illustrative purposes and is not intended to limit the scope of the invention. As used herein, the singular form may include the plural form unless the context clearly indicates otherwise.

[0056] Furthermore, when used to describe and assert the contents of this disclosure, expressions such as “comprise,” “consist of,” and “have” should be interpreted in a non-exclusive manner. Unless specifically stated to the contrary, they mean that the corresponding constituent elements may be included. Therefore, they should be interpreted as including other constituent elements rather than excluding other constituent elements.

[0057] Furthermore, when describing the constituent elements of embodiments of this utility model, terms such as first, second, A, B, (a), and (b) may be used. These terms are only used to distinguish the constituent element from other constituent elements, and the nature, order, or sequence of the corresponding constituent elements are not limited to these terms.

[0058] When a constituent element is described as being "connected" or "combined" with other constituent elements, it should be understood that the constituent element can be directly connected or combined with the other constituent elements, but it can also be "connected" or "combined" with another constituent element between the constituent element and the other constituent elements.

[0059] Spatially related terms such as "beneath," "below," "lower," "above," and "upper" may be used to facilitate understanding of one element or feature shown in the accompanying drawings and other elements or features. These spatially related terms are intended to facilitate understanding of the invention in various manufacturing or usage states, and are not intended to limit the invention. For example, if an element or feature in the drawing is flipped, the element or feature described using "beneath" or "below" becomes "above" or "upper." Therefore, "beneath" is a concept that includes "above" or "below."

[0060] The embodiments and configurations shown in the accompanying drawings described in this specification are merely the most preferred embodiments of this utility model and do not represent the entirety of the technical concept of this utility model. Therefore, it should be understood that various equivalents and modifications may exist to replace them. Furthermore, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the essence of this utility model are omitted.

[0061] Typically, display devices may include various panels or films, which may be manufactured in a laminated or attached manner.

[0062] The display device may include a cover window, an anti-reflective layer, a display panel, and a cover plate.

[0063] For example, a display device may include a display panel. The display panel can provide an image via an array of multiple pixels arranged in a two-dimensional pattern. For this purpose, the display panel may include a substrate and light-emitting elements disposed on the substrate. The light-emitting elements may include, for example, inorganic light-emitting diodes or organic light-emitting diodes, but the type of light-emitting element is not limited thereto. The substrate of the display panel may include glass, sapphire, or plastic. For example, the substrate of the display panel may be ultra-thin glass (ULT), whose strength is strengthened by methods such as chemical strengthening or thermal strengthening. However, it is not limited to this; it can also have flexible or bending properties.

[0064] For example, a display device may include a cover window attached to the top of a display panel. The cover window functions to protect the top of the display panel. For example, the cover window may be configured to cover and protect the top of the display panel. Here, the "top" of the display panel may be defined as the surface facing the direction in which an image is provided to the display panel. The cover window may include glass, sapphire, or plastic. For example, the cover window may be ultra-thin glass (Ultra-Thin Glass), whose strength is enhanced by methods such as chemical strengthening or thermal strengthening. However, it is not limited to this; it can also have flexible or bending properties.

[0065] On the other hand, an anti-reflective film can also be disposed between the display panel and the cover window. External light can be incident on the display device, but the external light can be reflected from various electrodes or wirings included in the substrate of the display panel. The anti-reflective film can prevent the external light from being reflected and thus identified. The anti-reflective film may include polarizers and phase retarders. The anti-reflective film may include a stretched film type polarizer and / or a phase retarder. Optionally, the anti-reflective film may include color filters. The color filters may have a predetermined arrangement. The color filters may be arranged taking into account the emission colors of the pixels included in the display substrate. In addition, the anti-reflective film may also include a black matrix adjacent to the color filters. For example, the anti-reflective film may also be attached to the display substrate.

[0066] Additionally, the display device may include a cover plate attached to the underside of the display panel. The cover plate may be disposed below the protective layer. The cover plate can protect other components of the display panel from external impacts, vibrations, and physical damage. Furthermore, the cover plate can improve the rigidity of the overall display structure to enhance durability, and can also perform thermal management functions to effectively disperse internally generated heat and / or electromagnetic wave shielding functions to reduce electromagnetic interference (EMI) to protect the performance of the display device.

[0067] Cover plates typically have a thin sheet structure with four sides or a rectangular shape. However, recently, the shape of the display panel is becoming more diverse depending on the applicable product, or the shape of the cover plate is becoming more diverse depending on the configuration of the components configured on the display panel.

[0068] This invention provides a display manufacturing apparatus for attaching various panels or films constituting a display device. In particular, in various embodiments of this invention, a display manufacturing apparatus is provided that can effectively attach complex panels of various widths, rather than simple quadrilateral or rectangular panels, to a single panel.

[0069] For ease of explanation, the panels attached to each other can be referred to as the first component 10 (see reference). Figure 5 ) and second component 20 (refer toFigure 5 ).

[0070] Alternatively, exemplarily, the second component 20 may be described as a display panel, which will be attached to the attachment roller portion 110 (see reference 110). Figure 1 The first component 10, which is attached to the underside of the second component 20 by contact and pressing, is described as a cover plate. However, this is exemplary, and it is clear that the first component 10 and the second component 20 may comprise any panel or film that is attached to each other to form a display device.

[0071] Hereinafter, a display manufacturing apparatus according to various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0072] Figure 1 This is a perspective view of a display manufacturing apparatus according to an exemplary embodiment of the present invention. Figure 2 This is an exploded perspective view of the connection portion between the attachment roller section 110 and the roller drive section 140 of a display manufacturing apparatus according to an exemplary embodiment of the present invention. Figure 3 This is a schematic diagram illustrating the configuration structure of the attachment roller portion 110 and the support roller portion 150 according to an exemplary embodiment of the present invention.

[0073] First, refer to Figure 1 as well as Figure 2 The display manufacturing apparatus according to various embodiments of the present invention may include a roller assembly 100, a pressing device 200, and a posture control device 300.

[0074] The display manufacturing apparatus may include a roller assembly 100. The roller assembly 100 may contact and press the first component 10 (see reference). Figure 5 Next, attach the first component 10 to the second component 20 (see reference). Figure 5 ).

[0075] The roller assembly 100 of this invention is configured to selectively use any one of the plurality of attachment roller sections 110 as needed.

[0076] For example, the roller assembly 100 is formed such that each attachment roller portion 110 has a contact area 111 of different lengths from each other. The roller assembly 100 can select an attachment roller portion 110 with a corresponding contact area 111 of a certain length from the multiple attachment roller portions 110 according to the width of the first component 10 to press the first component 10.

[0077] Therefore, in this invention, even when the first component 10 is formed such that each region has a different width in its overall area, all regions with different widths can be attached using only one roller assembly 100. Furthermore, in this invention, the roller assembly 100 is arranged in a rotating manner, so even for regions with different widths that are formed adjacent to each other, the attachment process can be performed using a continuous process.

[0078] To be further specific, the roller assembly 100 according to various embodiments of the present invention may include an attachment roller portion 110.

[0079] The attachment roller 110 can contact the underside of the first component 10 to press and attach the first component 10 toward the second component 20. Multiple attachment rollers 110 can be configured. For example, four attachment rollers 110 can be configured, but not limited to this; two or more can also be configured. Furthermore, the number of attachment rollers 110 is not necessarily even; an odd number can also be configured.

[0080] Reference Figure 3 In an exemplary embodiment, the attachment rollers 110 may also be configured as six, and the six attachment rollers 110 may be connected by roller fixing parts 120 (see reference 120). Figure 1 The attachment rollers 110 are arranged radially around the central axis of the first component 10. The support roller 150, described later, can be positioned at the center of the radially arranged attachment rollers 110. For example, if one of the plurality of attachment rollers 110 is selected, it may have a connection with the first component 10 (see reference 10). Figure 5 The contact area 111 corresponding to the width of the contact area 111 (refer to) Figure 1 If the attachment roller 110 is attached to the corresponding attachment roller 110, the support roller 150 can be displaced to approach the corresponding attachment roller 110. A detailed explanation of this will be given later.

[0081] The attachment roller portion 110 can be formed extending in the length direction, where the length direction can refer to the same direction as the width direction of the first component 10 (e.g.: Figure 1 The direction parallel to the X-axis direction. The two ends of the attachment roller section 110 along the length direction can be respectively attached to the roller fixing section 120.

[0082] Refer again Figure 1 as well as Figure 2 Each attachment roller portion 110 may include components connected to the first component 10 (see reference 10). Figure 5 The contact area 111 of the attachment roller 110 is in direct contact with the roller, and the shafts 112 are respectively disposed at both ends of the contact area 111 in the longitudinal direction. That is, the contact area 111 of the attachment roller 110 can be connected to the roller fixing part 120 through the shafts 112.

[0083] In an exemplary embodiment, each attachment roller portion 110 may have contact areas 111 of different lengths. That is, the contact areas 111 of each attachment roller portion 110 may be formed to have different lengths. The two ends of the plurality of attachment roller portions 110 in the longitudinal direction are coupled to a pair of roller fixing portions 120, and rotate as the roller fixing portions 120 rotate. Therefore, the overall length in the longitudinal direction of each attachment roller portion 110 may be configured to be all the same.

[0084] Each attachment roller portion 110 can be rotatably coupled relative to the roller fixing portion 120 about the central axis of the shaft 112. Therefore, if an attachment roller portion 110 corresponding to the width of the first component 10 is selected, the selected attachment roller portion 110 can rotate and slide relative to the underside of the first component 10.

[0085] The attachment roller portion 110 can contact the lower surface of the first component 10 on its upper side, and can contact the support roller portion 150 on its lower side. Since the attachment roller portion 110 extends in the length direction, it may sag or deform during the pressing of the lower surface of the first component 10. However, in this invention, the lower surface can be supported by the support roller portion 150, thereby preventing the attachment roller portion 110 from sag or deforming.

[0086] In an exemplary embodiment, the contact area 111 of the attachment roller portion 110 may include a material with excellent wear resistance. For example, the contact area 111 of the attachment roller portion 110 may include polycrystalline silicon carbide (PSC), polyurethane, etc. Polycrystalline silicon carbide can have high hardness and ensure excellent wear resistance, and its high heat resistance and chemical resistance can ensure excellent durability. In addition, polyurethane not only has excellent wear resistance, heat resistance, and chemical resistance, but also has high elasticity, thereby preventing damage to the roller surface and maintaining uniform quality for the attachment object.

[0087] In this invention, each attachment roller portion 110 having a contact area 111 of different lengths can selectively use an attachment roller portion 110 having a contact area 111 of corresponding length, depending on the width of the first component 10 that is the object to be pressed.

[0088] The roller assembly 100 may include roller fixing portions 120. The roller fixing portions 120 may be a pair, with the pair of roller fixing portions 120 being coupled to both ends of the plurality of attached roller portions 110 in the longitudinal direction.

[0089] For example, the roller fixing portion 120 can be configured as a disc shape. A pair of roller fixing portions 120 can rotate about a first rotation axis C1 while in conjunction with a plurality of attachment roller portions 110. In this case, the first rotation axis C1 can be a virtual rotation axis extending in a direction parallel to the length direction of the attachment roller portions 110. For example, the first rotation axis C1 can be formed coaxially with the center of the disc-shaped roller fixing portion 120.

[0090] A pair of roller fixing portions 120 can be rotatably coupled to the roller support frame 130. The roller fixing portion 120 on either side of the pair of roller fixing portions 120 can be connected to the roller drive portion 140. If the roller fixing portion 120 rotates via the roller drive portion 140, the plurality of attached roller portions 110 coupled to the roller fixing portion 120 can also rotate.

[0091] Multiple attachment roller portions 110 can be arranged radially with a distance between them from the center of the disc-shaped roller fixing portion 120. For example, the distances between each attachment roller portion 110 and the center of the roller fixing portion 120 can be the same or different.

[0092] The roller fixing portion 120 may incorporate not only the attachment roller portion 110 but also the support roller portion 150. For example, in a disc-shaped roller fixing portion 120, the support roller portion 150 may be disposed inside the attachment roller portion 110, which is arranged radially. For example, the support roller portion 150 may be disposed at the center of the roller fixing portion 120. The support roller portion 150 may be rotatably attached to the roller fixing portion 120.

[0093] In an exemplary embodiment, the support roller portion 150 in the roller fixing portion 120 can be configured to contact the contact area 111 of each attachment roller portion 110. Therefore, in this invention, when the second component 20 (see reference) is present in one of the plurality of attachment roller portions 110, Figure 5 When the attachment roller 110, whose width is selected, rotates, it can be configured such that the support roller 150, which is in contact with the lower side, also rotates together.

[0094] The roller assembly 100 may also include a roller support frame 130. The roller support frame 130 supports the roller fixing portions 120, which are combined with a plurality of attachment roller portions 110, so that they are rotatable. In an exemplary embodiment, the roller support frame 130 may include a horizontal roller frame 132 extending parallel to the attachment roller portions 110 and a pair of vertical roller frames 131 disposed at both ends of the horizontal roller frame 132 in a vertical direction. In the pair of vertical roller frames 131, the pair of roller fixing portions 120 may be rotatably coupled respectively.

[0095] On the other hand, the roller support frame 130 is connected to the pressing device 200 described later, so that it can move in the vertical direction via the pressing device 200. For example, the horizontal roller frame 132 of the roller support frame 130 can be connected to the second vertical frame 230 of the pressing device 200 and move in the vertical direction.

[0096] The roller assembly 100 according to various embodiments of the present invention may include a roller drive unit 140. The roller drive unit 140 can rotate a roller fixing unit 120 that incorporates a plurality of attached roller units 110. The roller drive unit 140 may also be adapted to an actuator of any known manner capable of providing rotational force to the roller fixing unit 120.

[0097] For example, the roller drive unit 140 can be coupled to the vertical roller frame 131. The rotation output shaft of the roller drive unit 140 can be coupled to the roller fixing unit 120 to rotate the roller fixing unit 120. For example, the rotation output shaft of the roller drive unit 140 can also be connected to the roller fixing unit 120 via the connecting member 170.

[0098] On the other hand, the roller assembly 100 may include a support roller portion 150 for preventing sagging or deformation of the attachment roller portions 110. The support roller portion 150 may be arranged parallel to the plurality of attachment roller portions 110. The support roller portion 150 may be rotatably coupled to the roller fixing portion 120. The support roller portion 150 may be disposed at the central portion of the plurality of attachment roller portions 110 that are radially coupled to the roller fixing portion 120. For example, the support roller portion 150 may be coaxially arranged with the central axis of the roller fixing portion 120.

[0099] The support roller portion 150 can be configured to contact and rotate together with the contact area 111 of the attachment roller portion 110. For example, the support roller portion 150 can be configured to contact an attachment roller portion 110 selected from a plurality of attachment roller portions 110 according to the width of the second member 20. The support roller portion 150 can contact the selected attachment roller portion 110 and rotate together, supporting the attachment roller portion 110.

[0100] For example, the support roller portion 150 may be configured to contact and support at least one of the plurality of attachment roller portions 110. Alternatively, the support roller portion 150 may be configured to contact all of the plurality of attachment roller portions 110.

[0101] Here, multiple attachment rollers 110 and support rollers 150 may be described as rollers.

[0102] For example, such as Figure 3 As shown, the support roller portion 150 can be configured to be displaced to contact at least one of the plurality of attachment roller portions 110. For example, the two ends of the support roller portion 150 in the longitudinal direction can be respectively located at the roller fixing portion 120 (see reference). Figure 1The rollers are joined in a way that allows for displacement. For example, a moving groove (not shown) can be formed in the roller fixing part 120 so that the support roller part 150 can move, and the support roller part 150 can be displaced along the moving groove in a direction toward the attachment roller part 110.

[0103] On the other hand, in various embodiments of the present invention, in the contact area 111 of each of the plurality of attachment roller portions 110 (refer to...) Figure 1 The attachment rollers 150 can be formed to have all different lengths. Therefore, the length of the support roller 150 used to support the attachment roller 110 can be configured to be equal to or greater than the length of the contact area 111 of the attachment roller 110 with the longest contact area 111 among the plurality of attachment rollers 110.

[0104] On the other hand, refer to Figure 2 In order to enable the roller fixing part 120 to be rotatably coupled relative to the roller support frame 130, the display manufacturing apparatus according to various embodiments of the present invention may further include a bearing 160 and a connecting part 170.

[0105] In an exemplary embodiment of this utility model, in order to conform to the second component 20 (refer to...) Figure 5 By selectively using corresponding attachment roller portions 110 to adjust the width of the roller, the roller fixing portion 120, which incorporates multiple attachment roller portions 110, can be rotated. Therefore, in order to allow the roller fixing portion 120 to rotate smoothly on the roller support frame 130, a bearing 160 may be included.

[0106] Additionally, the display manufacturing apparatus of this invention may include a connecting member 170 for effectively transmitting the driving force of the roller drive unit 140 to the disc-shaped roller fixing unit 120. For example, the connecting member 170 may be directly coupled to the output shaft of the roller drive unit 140 to transmit rotational force to the roller fixing unit 120.

[0107] Reference Figure 1 The display manufacturing apparatus according to various embodiments of the present invention may include a pressing device 200. In the present invention, the pressing device 200 can cause the roller assembly 100 to move in the vertical direction (e.g.: Figure 1 (in the z-axis direction). For example, the pressing device 200 can move the roller assembly 100 closer to the second component 20 (see reference). Figure 5 Press in the direction of ).

[0108] In an exemplary embodiment, the pressing device 200 may include a base plate 210, a first vertical frame 220, a second vertical frame 230, and a vertical drive unit 240.

[0109] The roller assembly 100 can be attached to the upper side of the base plate 210. Therefore, the base plate 210 can serve as a reference for the vertical movement of the roller assembly 100. For example, the base plate 210 can be configured as a flat plate with a predetermined area, but is not limited thereto.

[0110] The first vertical frame 220 can be fixed above the base plate 210 and extends from the base plate 210 in the vertical direction. A first hook 251 of the stop portion 250 can be disposed on one side of the first vertical frame 220.

[0111] In the first vertical frame 220, the second vertical frame 230 can be coupled in a manner that allows it to move vertically. The first vertical frame 220 can guide the vertical movement of the second vertical frame 230. For example, a guide rail (not shown) extending vertically can be configured in the first vertical frame 220. The second vertical frame 230 can be coupled to this guide rail and move relative to the first vertical frame 220 in the vertical direction.

[0112] The upper end of the second vertical frame 230 can be connected to the roller assembly 100, and it extends in the vertical direction. The second vertical frame 230 can be coupled to the first vertical frame 220. The second vertical frame 230 can be configured to move relative to the first vertical frame 220 in the vertical direction. For example, a guide (not shown) extending in the vertical direction and slidably coupled to the guide rail of the first vertical frame 220 can be disposed in the second vertical frame 230. The second vertical frame 230 can be connected to the vertical drive unit 240 and moved in the vertical direction by the vertical drive unit 240.

[0113] The vertical drive unit 240 can provide a driving force to move the roller assembly 100 in the vertical direction. The vertical drive unit 240 can also provide a pressing force to press the roller assembly 100 toward the second member 20. The vertical drive unit 240 is coupled to the base plate 210 and supports the second member 20 for vertical movement, thereby enabling the roller assembly 100 to move in the vertical direction. The vertical drive unit 240 can also be fitted with an actuator of any known manner capable of providing a driving force for linear movement of the second vertical frame 230 in the vertical direction.

[0114] In this invention, the roller assembly 100 rotates in the roller fixing part 120 so that the selected attachment roller part 110 contacts the first part 10 (see reference). Figure 5 During the rotation process, the first component 10 can be pressed to attach the first component 10 to the second component 20.

[0115] On the other hand, this invention may also include a control unit for controlling the pressing pressure provided to the roller assembly 100 by the vertical drive unit 240. For example, the first component 10 pressed by the roller assembly 100 may include regions of varying thicknesses throughout its overall area, but the control unit can control the pressing pressure caused by the vertical drive unit 240 in stages according to the thickness of the first component 10. Therefore, even if the first component 10 to be attached has regions of varying thicknesses throughout its overall area, the display manufacturing apparatus of this invention can enable uniform attachment to the entire area.

[0116] In an exemplary embodiment, the pressing device 200 may include a stop 250 that restricts the vertical movement of the second vertical frame 230. The stop 250 may include a first hook 251 disposed on one side of the first vertical frame 220 and a second hook 252 disposed on one side of the second vertical frame 230. If the second vertical frame 230 moves upward by the vertical drive 240, the first hook 251 and the second hook 252 engage with each other at the upper stop point, thereby restricting the upward movement of the second vertical frame 230.

[0117] On the other hand, the display manufacturing apparatus according to various embodiments of the present invention may include a posture control device 300 for changing the position of the roller assembly 100 relative to the first component 10.

[0118] In order to ensure that the first component 10 is attached to the entire area of ​​the second component 20 uniformly and precisely, it is necessary to ensure the accuracy and precision of the position of the roller assembly 100 pressing the first component 10.

[0119] As described above, the multiple attachment rollers 110 of the display device of this invention rotate, and the first component 10 is pressed by one of the selected attachment rollers 110. At this time, the multiple attachment rollers 110 may vibrate or shake while rotating by the roller drive unit 140, which may cause deviations in the position of the selected attachment roller 110 or the alignment of the selected attachment roller 110 with respect to the first component 10 during the rotation of the roller fixing unit 120.

[0120] Therefore, the display manufacturing apparatus of this invention may include a posture control device 300 for changing and adjusting the position of the roller assembly 100. The posture control device 300 can change and adjust the spatial position of the roller assembly 100.

[0121] In an exemplary embodiment, the posture control device 300 is disposed below the base plate 210 of the pressing device 200 to adjust the position of the base plate 210, thereby changing or adjusting the position of the roller assembly 100.

[0122] For example, the posture control device 300 may include causing the roller assembly 100 to move along the length direction of the attachment roller portion 110 (e.g.: Figure 1 The first posture control drive unit 310 moves in the X-axis direction and the attachment direction of the first component 10 and the second component 20 is perpendicular to the length direction of the attachment roller 110 (e.g., the attachment direction of the first component 10 and the second component 20). Figure 1 The second posture control drive unit 320 moves in the Y-axis direction.

[0123] Additionally, the posture control device 300 may include a third posture control drive unit that rotates the roller assembly 100 about a virtual second rotation axis C2 extending in the vertical direction. However, in the exemplary embodiment, the third posture control drive unit is not provided separately, and rotation control can also be performed by simultaneously driving the first posture control drive unit 310 and the second posture control drive unit 320.

[0124] In an exemplary embodiment, the first posture control drive unit 310 may also include a first-1 posture control drive unit 310a for moving the roller assembly 100 in the +X axis direction and a first-2 posture control drive unit 310b for moving the roller assembly 100 in the -X axis direction.

[0125] In addition, in an exemplary embodiment, the second posture control drive unit 320 may also include a second-1 posture control drive unit 320a for moving the roller assembly 100 in the +Y axis direction and a second-2 posture control drive unit for moving the roller assembly 100 in the -Y axis direction.

[0126] Figure 4 as well as Figure 5 This is a diagram that schematically illustrates a method for manufacturing a display using a display manufacturing apparatus according to an exemplary embodiment of the present invention.

[0127] Reference Figure 4 as well as Figure 5 The display manufacturing apparatus according to various embodiments of the present invention may include a first worktable S1 on which a first component 10 is disposed, and a second worktable S2 on which a second component 20 is disposed. Firstly, in order to perform the attachment process of the second component 20, the first component 10 may be disposed on top of the first worktable S1 for preparation, and the second component 20 may be disposed below the second worktable S2 for preparation. At this time, the second worktable S2 may be disposed above the first worktable S1.

[0128] Furthermore, the display manufacturing apparatus of this invention can be configured on one side of the first worktable S1. Specifically, the roller assembly 100 of the display apparatus can be configured adjacent to one side of the first worktable S1.

[0129] On the other hand, here, the support roller portion 150 is shown as being separated from the contact area 111 of each attachment roller portion 110, but this is an exaggerated representation for ease of understanding. In embodiments of the present invention, in order to prevent sagging or deformation of the attachment roller portion 110 when it rotates, the support roller portion 150 may be configured to contact the contact area 111 of the attachment roller portion 110.

[0130] Subsequently, the first worktable S1 and the roller assembly 100 can move toward the second worktable S2 towards the attachment position for attachment of the first component 10. At this time, the first worktable S1 can be tilted at a predetermined slope so that one side of the first component 10 is close to the second component 20 (e.g., refer to...). Figure 5 S1).

[0131] First, in the roller assembly 100 of this utility model, the roller fixing part 120 (see reference) Figure 1 The attachment roller portion 110, which can be rotated, is positioned on the uppermost side with a contact area 111 having a length corresponding to the width of one side of the first component 10.

[0132] For ease of explanation, the attachment roller section 110 used for the first attachment can be referred to as the first attachment roller section 110.

[0133] With the selected first attachment roller 110 positioned at the uppermost of the plurality of attachment rollers 110 (e.g., the side closest to the first component 10), the first attachment of the first component 10 and the second component 20 can be achieved by pressing the first component 10 by raising the roller assembly 100.

[0134] At this time, the display manufacturing apparatus of this invention, including the roller assembly 100, can move forward toward the other side of the first worktable S1 while achieving attachment to achieve continuous attachment of the first component 10 and the second component 20.

[0135] Figure 6 as well as Figure 7 This is a diagram illustrating the process of manufacturing a display using a display manufacturing apparatus according to an exemplary embodiment of the present invention. Figure 8 This is a flowchart illustrating the process of manufacturing a display using a display manufacturing apparatus according to an exemplary embodiment of the present invention.

[0136] Reference Figure 6 to Figure 8 The present invention describes in detail the process of manufacturing a display using a display manufacturing apparatus according to an exemplary embodiment of the present invention.

[0137] First, as mentioned above and as... Figure 6As shown in (a), the first attachment area of ​​the first component 10 can be a region with a first width in the overall area of ​​the first component 10. In this case, the attachment roller portion 110 for pressing the first component 10 can be selected to have a contact area 111 with a length corresponding to the first width (see reference). Figure 1 The first attachment roller portion 110. If the roller fixing portion 120 (refer to) Figure 1 When the first attachment roller 110 is rotated and configured to reach the uppermost side, attachment is performed by pressing the first component 10 with the first attachment roller 110.

[0138] Subsequently, if the attachment by the first attachment roller section 110 is completed, then the roller assembly 100 (refer to...) Figure 1 It can drop again.

[0139] When the control unit senses a region in the first component 10 that has a width different from the first width through the sensor unit, it can select the corresponding attachment roller 110 again to perform the attachment process.

[0140] For example, such as Figure 6 As shown in (b), the first component 10 may include a region with a second width that is larger than the first width in its overall area. In this case, in this invention, a second attachment roller 110 with a contact area 111 having a length corresponding to the second width can be selected from among a plurality of attachment rollers 110. If the roller fixing part 120 rotates and the second attachment roller 110 is configured to reach the uppermost side, attachment is continuously performed by pressing the first component 10 with the second attachment roller 110.

[0141] Afterwards, once the attachment by the second attachment roller section 110 is completed, the roller assembly 100 can descend again.

[0142] When the control unit senses an area in the first component 10 that has a width different from the second width through the sensor unit, it can select the corresponding attachment roller 110 again to perform the attachment process.

[0143] For example, such as Figure 6 As shown in (c), the first component 10 can contact a region having a second width, including a region having a third width different from the second width. In this invention, a third attachment roller 110 with a contact area 111 of a plurality of attachment rollers 110 having a length corresponding to the third width can be selected. If the roller fixing part 120 rotates and the third attachment roller 110 is configured to reach its uppermost position, continuous attachment is performed by pressing the first component 10 with the third attachment roller 110.

[0144] In an exemplary embodiment, the control unit of this invention can select an attachment roller 110 of a corresponding length from the input shape and width of the first component 10.

[0145] Alternatively, the display manufacturing apparatus of this invention may further include a sensor unit for sensing the shape and width of the first component 10, and using the shape and width of the first component 10 sensed in the sensor unit to select an appropriate attachment roller 110 in real time during the attachment process. For example, the sensor unit may include an optical sensor or a vision sensor, but is not limited thereto.

[0146] On the other hand, refer to Figure 7 The display manufacturing apparatus of this invention can utilize a roller assembly 100 having a plurality of attachment roller sections 110 (see reference 100). Figure 1 () to correspond to various shapes of the first component 10. For example, such as Figure 6 As shown, the display manufacturing apparatus can be applied not only to cases where the shape of the first component 10 forms a pressing area on the central side in the width direction, such as... Figure 7 As shown, this method can also be applied to cases where the shape of the first component 10 is biased to either side of the width direction.

[0147] For example, the control unit can control the posture control device 300 based on values ​​input for the shape and width of the first component 10 or values ​​sensed by the sensor unit. For example, the control unit can drive the first posture control drive unit 310 of the posture control device 300 to move the roller assembly 100 in the longitudinal direction of the attachment roller 110. For example, the control unit selects an attachment roller 110 having a length corresponding to the width of the first component 10, and moves the selected attachment roller 110 in the longitudinal direction, thereby allowing the contact area 111 of the attachment roller 110 (see reference) to be moved. Figure 1 Positioned to conform to the shape of the first component 10.

[0148] Figure 9 This is a flowchart illustrating a display manufacturing method according to an exemplary embodiment of the present invention.

[0149] Reference Figure 9 The display manufacturing method may include roller assembly 100 (see reference). Figure 1 (910) The step of moving to the attachment position.

[0150] Subsequently, the display manufacturing method may include using multiple attachment rollers 110 (see reference 110). Figure 1 The first attachment roller 110 in the first component 10 (see reference) presses the first component 10. Figure 5 The first pressing step (920). As described above, at this time, the width of the first component 10 can be described as the first width.

[0151] The display manufacturing method may include a rotation step (930) in which the roller assembly 100 rotates according to the shape of the first component 10.

[0152] Additionally, the display manufacturing method may include using a contact area 111 (refer to) of one of a plurality of attachment rollers 110 having contact with the first attachment roller 110. Figure 1 The second attachment roller portion 110, with a contact area 111 of different lengths, presses the first component 10 in a second pressing step (940). At this time, the width of the first component 10 can be described as having a second width that is different from the first width.

[0153] As described above, the display manufacturing apparatus according to various embodiments of the present invention can use a roller device to correspond to various shapes of the attached object.

[0154] The display manufacturing apparatus according to various embodiments of the present invention can reduce equipment replacement time and costs.
