Description

The present application relates to an attachment device and a method for manufacturing a laminate using the same.

In the manufacturing process of a display device such as an LCD (Liquid Crystal Display) or other electronic products, a process of attaching two or more parts to each other is often performed. As an example of such a process, there can be mentioned a case where an LCD panel and an optical film such as a polarizing film or a retardation film are attached to each other. For example, in order to construct a stereoscopic video display device, as schematically shown in FIG. 1, video signals for right and left eyes (hereinafter referred to as “R signal” and “L signal”) are used. The liquid crystal panel 100 formed by dividing the region to be generated and the optical filter 200 on which a pattern for adjusting the polarization states of the R and L signals to be different from each other must be attached. The stereoscopic image display apparatus has a region (hereinafter referred to as “FR region”) in which a signal transmitted in a region (hereinafter referred to as “UR region”) of the liquid crystal panel 100 that generates the R signal adjusts the polarization state of the R signal of the optical filter. In the same manner, a signal transmitted in a region (hereinafter referred to as “UL region”) of the liquid crystal panel 100 that generates the L signal of the liquid crystal panel 100 adjusts the polarization state of the L signal of the optical filter (hereinafter referred to as “the L signal”). Through the “FL region”), the R signal and the L signal are separated and transmitted to the viewer. Therefore, the UR region of the liquid crystal panel and the FR region of the optical filter are matched, and the liquid crystal panel and the optical filter are attached so that the UL region of the liquid crystal panel and the FL region of the optical filter are matched with high accuracy. Is required. If there is a portion where the UR region of the liquid crystal panel is attached to the FL region of the optical filter, the R signal is incident on the left eye, not the right eye. Accordingly, in the stereoscopic image display apparatus, the crosstalk indicated by the percentage value of the R signal incident on the left eye with reference to the L signal incident on the left eye becomes high, making it difficult to view the stereoscopic image. Problem occurs. Therefore, in the case of a stereoscopic image display device, it is required to manufacture using a sticking device that can attach a liquid crystal panel and an optical filter with high accuracy.

The present application provides a deposition apparatus and a method of manufacturing a laminate using the same.

In one embodiment of the present application, the first component is installed so as to be held, and a holding table in which one or more holes are formed, and the first component is held on the holding table, A first support portion including a fixing device installed to fix the first component to the holding table in the suction process through the hole; a second support installed to fix the second component And a transfer device installed to change the relative position of the first support portion and the second support portion so that the fixed first and second parts are stacked on each other. .

In the present specification, the meaning of “installed so as to hold the first part” means that the attachment device is installed so that the first part is held on the holding stand in the course of performing the attaching process. The attachment device that is not driven may not include the first component. The meaning of “installed so as to fix the second part” can be interpreted in the same way.

In the present specification, “first part”, “second part”, “first support part”, and “second support part” are arbitrarily ordered in order to describe the two parts and the support part. Is. Therefore, the configuration of the first part exemplified below can be located in the second support part, or the configuration of the second part can be located in the first support part.

In one example, the second support part may be installed so as to fix the second part by suction using suction. For example, like the first support portion, the second support portion is installed so as to hold the second component, and a holding base in which one or more holes are formed, If the two parts are held, a fixing device installed to fix the second part to the holding table in the suction process through the hole may be included.

In one example, in order to prevent a phenomenon in which the first or second component is bent toward the first or second support portion due to the suction force of the first or second support portion, the center of the first or second support portion is used. The suction input at can be adjusted to be weaker than the end.

In one example, in order to adjust the suction force at the center of the first or second support part to be weaker than the end part, the holding base includes a plurality of holes and is formed in the end part of the holding base. Can be higher than the density of holes formed in the central portion of the holding table. Here, the hole density means an area ratio of a plurality of holes per unit area. For example, if a plurality of holes have the same area, the high hole density can be understood as a large number of holes per unit area. Referring to FIG. 2, the end portion 1111 of the holding table divides the entire area of the holding table into three regions having the same area in the horizontal direction, and three regions having the same area in the vertical direction. When divided into two, it can mean a region located at the end. Accordingly, the central portion 1112 of the holding table may mean a region located at the center of the holding table excluding the end of the holding table.

As long as the holding table is formed with a hole, a configuration used in the industry can be used without limitation. For example, the holding table may use a mesh type plate.

In one example, the attachment device can be equipped with a multi-vision system that can identify the position of the first and second parts. For example, a multi-vision system includes a first vision camera installed to observe the state of a first part through an optical signal, a second vision camera installed to observe the state of a second part through an optical signal, and all A reflective lens can be included. Here, the meaning of observing the state of a part can be interpreted as meaning that the position of the part can be identified.

An exemplary multi-vision system can enable a vision structure even in a closed structure where the first and second parts are substantially in close contact. In the closed structure, the separation distance between the first component and the second component is, for example, 10 mm or less, 9 mm or less, 8 mm or less, 7 mm or less, 6 mm or less, 5 mm or less, 4 mm or less, 3 mm or less, 2 mm or less, or 1 mm or less. Can do. In addition, since the adhesion accuracy between the first component and the second component can be improved as the first component and the second component are in close contact with each other, the first component and the second component in the closed structure can be improved. The lower limit of the separation distance is not particularly limited, and can be, for example, 0 cm or more than 0 cm.

The total reflection lens may mean a lens that transmits light or reflects all light depending on an incident angle of light. Specifically, light incident on the total reflection lens can be transmitted as it is without refraction, can be refracted and transmitted, or can be totally reflected.

In one example, in the total reflection lens, the optical signal irradiated by the first vision camera or the optical signal irradiated by the second vision camera reaches the first or second component through the total reflection lens. Can be installed as follows.

Further, the total reflection lens, for example, either one of the optical signals passes through the total reflection lens, reaches one of the first and second components, and the other The signal is totally reflected or refracted by the total reflection lens, and can be placed so as to reach the other part of the first and second parts. A signal that passes through the total reflection lens and reaches the first or second component can be transmitted through the total reflection lens without refraction or can be refracted and transmitted.

The optical signal that passes through the total reflection lens and reaches one of the first and second components and is totally reflected or refracted by the total reflection lens, and the other component of the first and second components The total reflection lens can be installed so that the optical signal reaching the center reaches the same part of the first and second parts.

Here, the same part of the first part and the second part are, for example, penetrated through any one part of the first part in a state where the first and second parts are arranged so as to overlap, A part where a virtual line perpendicular to the penetrating surface abuts on the second part can be described as the same part as any one part of the first part. However, in consideration of a substantial error, a region within a radius of 5 mm, within 3 mm, within 1 mm, or within 0.5 mm at a portion where the virtual line contacts the second part can be included in the same portion.

By observing the same part of the first and second parts through such a multi-vision system, the first and second parts can be stacked in a target array.

In one example, in order to observe the same part of the first and second parts through the multi-vision system, the total reflection lens includes a part through which one of the optical signals is transmitted and a second optical signal. It can be installed so that the part that is totally reflected or refracted is the same.

Further, the total reflection lens can be installed such that one of the optical signals transmitted through the lens and the other optical signal totally reflected or refracted by the lens travel in the same direction.

Therefore, the total reflection lens is installed so that the part where one of the signals is transmitted and the part where the other signal is totally reflected or refracted are set so that the two signals travel in the same direction. And the same part of the second part can be observed.

In one example, the first vision camera, the second vision camera, and the total reflection lens may be installed inside the first or second support unit.

In one example, the deposition apparatus may further include a deposition roller installed to apply pressure to the stack of first and second components that are stacked together by the transfer unit.

In one example, the first and second parts can be attached by a method employed in the industry. For example, the first and second parts can be attached by conventional adhesives or adhesives. Therefore, in one example, the adhesion roller applies pressure to the laminated body in which a normal adhesive or pressure-sensitive adhesive is interposed between the first and second parts, and the first and second parts Can be attached.

In one example, the first component may be a liquid crystal panel or the like. In one example, the second component may be an optical film or the like. The optical film is not particularly limited as long as it can be attached to a liquid crystal panel, and may be, for example, a polarizing plate, a retardation film, a protective film, an optical filter for stereoscopic video display, and the like.

In one example, the first component may be a liquid crystal panel in which UR and UL regions are formed, and the second component may be a stereoscopic image display optical filter in which FR and FL regions are formed. Accordingly, the attachment device can be, for example, a part of a stereoscopic video display device manufacturing apparatus or a stereoscopic video display device manufacturing apparatus.

In another embodiment of the present application, the first part is positioned on a holding table in which one or more holes are formed, and the first part is fixed to the holding table by suction through the holes, and the fixing is performed. Moving the relative positions of the first component and the second component such that the first component and the second component fixed to the second support portion are stacked on each other. The present invention relates to a laminate manufacturing method.

In one example, the method for manufacturing the laminate of the first and second components can be performed using the above-described attachment device.
The second component can be fixed to the second support part by suction using suction, for example.

In one example, in order to prevent a phenomenon in which the first or second component is bent toward the first or second support portion due to the suction force of the first or second support portion, the center of the first or second support portion is used. The suction input at can be adjusted to be weaker than the end.

In one example, in order to adjust the suction input at the center of the first or second support portion to be weaker than the end portion, the suction input sucked through the hole at the end portion of the holding base is the suction input at the central portion of the holding base. Can be adjusted to be larger. As described above, the end and center of the holding table can be understood with reference to FIG.

In one example, a pattern including first and second regions having different characteristics is formed on the first component, and a pattern including third and fourth regions having different characteristics is formed on the second component. It may be. The first and second parts may be stacked such that the first and third regions overlap with each other and the second and fourth regions overlap with each other.

In one example, the first component may be a stereoscopic image display liquid crystal panel including a UR region as a first region and a UL region as a second region. The second component may be a stereoscopic image display optical filter including an FR region as a third region and an FL region as a fourth region. Therefore, the three-dimensional image display liquid crystal panel and the three-dimensional image display optical filter are stacked such that the UR region and the FR region overlap with each other, and the UL region and the FL region overlap with each other. Can be.

In one example, the method for manufacturing a laminate further uses a multi-vision system capable of identifying the positions of the first and second parts in a state where the first part and the second part form a closed structure. Can do.

For example, as described above, the multi-vision system can be driven by including a first vision camera, a second vision camera, and a total reflection lens. That is, the total reflection lens may be installed so that an optical signal irradiated by the first or second vision camera reaches the first or second component through the total reflection lens. The method for driving the multi-vision system can be performed in the same manner as described above.

In one example, the method for manufacturing a laminate can include applying pressure to the laminate of first and second components with an adhesion roller. Further, for example, as described above, the laminated body of the first and second parts can be one in which a normal pressure-sensitive adhesive or adhesive is interposed between the first and second parts. Therefore, the laminated body of the first and second components in a state where a normal adhesive or pressure-sensitive adhesive is interposed can be attached with the pressure applied by the adhesion roller.

In one example, the manufacturing method of the laminate may be a part of a manufacturing method of a stereoscopic video display device or a manufacturing method of a stereoscopic video display device.

The exemplary attachment apparatus of the present application can attach various parts with high accuracy. For example, the attachment device can provide a 3D image display device in which a liquid crystal panel and an optical filter for 3D image display are attached with high accuracy to minimize a cross-talk phenomenon.

As an example, FIG. 1 is a diagram schematically illustrating a state in which a liquid crystal panel and a stereoscopic image display optical filter are attached to manufacture a stereoscopic image display device. (A) is a side view of the manufactured stereoscopic video display device, and (b) is a front view of the stereoscopic video display device.

FIG. 7 is a diagram schematically illustrating a state in which the multi-vision system of FIG. 3 observes the same part of the first part and the second part forming a closed structure. FIG. 8 is a diagram illustrating a stacked structure according to one embodiment. It is a figure which shows the manufacturing process of a body roughly.

Hereinafter, embodiments of the present application will be described with reference to FIGS. 3 to 5, but the scope of the present application is not limited by the embodiments shown below.

FIG. 3 schematically shows a side view of an attachment apparatus according to one embodiment, FIG. 4 shows a state in which the same apparatus as FIG. 3 is observed at the top, and FIG. It shows a state of observing the same device at the bottom. In FIG. 4, when the attachment device is observed at the top, the first component 100 is hidden by the first support portion 11 and cannot be seen. Therefore, the first component 100 is indicated by a dotted line and its position is indicated. In FIG. 5, since the second component 200 is not observed in the lower part of the adhesion apparatus, the second component 200 is indicated by a dotted line. 3 to 5, the same reference numerals denote the same parts.

In one example, the attachment device may include a first support part 11, a second support part 12, and a transfer part (not shown) as shown in FIG. FIG. 3 shows a state at any one point of the attaching device. In FIG. 3, the first support portion 11 and the second support portion 12 are arranged so as to face each other in the vertical direction. The arrangement of the support part 11 and the second support part 12 can be freely changed by the transfer part. As shown in FIG. 3, the attachment device may be a device in which a multivision system 13 is introduced and an attachment roller 14 is provided. As shown in FIG. 3 as an example, the multi-vision system 13 and the adhesion roller 14 may be incorporated in the second support unit 12. Particularly in the case of the multi-vision system 13, it can be incorporated in the first or second support to identify the position of the first and second parts of the closure structure. In this case, after identifying the attachment positions of the first and second parts, it is possible to immediately enter the attachment process, and the adhesion accuracy can be improved. However, the state shown in FIG. 3 is merely an example, and a position of the attachment device where the multi-vision system is introduced and a position where the attachment roller is mounted can be easily changed by those skilled in the art. .

With reference to FIG. 6 which is one example, the first support portion of the attachment apparatus will be described. The first support part 11 may include a holding base 111 installed to hold the first component 100 and the like. For example, the holding table 111 may have one or more holes 113 formed therein. The hole 113 of the holding stand 111 is expressed in an exaggerated manner in the drawing, and the actual hole 113 can be formed very narrow. For example, the holding table can be installed using a mesh plate.

In addition, the first support part 11 may include a fixing device 112 that can fix the first component 100 in a suction process through a hole. In FIG. 6, the direction in which gas is sucked into the fixing device 112 through the hole 113 of the holding base 111 is indicated by an arrow. The first support part 11 in FIG. 6 includes a holding base 111 and a fixing device 112, and an illumination 134 is installed in a portion where the hole of the holding base 111 is not formed, and is configured like the first support part 11 in FIG. can do.

The second support part may fix the second component using various methods. Among them, the second support part can be fixed on the second support part by being installed including a holding base and a fixing device like the first support part, for example.

Although not shown in FIGS. 3 to 5, the transfer unit is installed so that the relative positions of the first support unit and the second support unit can be changed. The adopted configuration can be used without limitation.

In the multi-vision system, the attachment device can attach the first and second parts with high accuracy.

In one example, attaching the first and second parts with high accuracy means that the first region 100 having a pattern including the first region and the second region having different characteristics is different from the third region having the different characteristics. And the second component 200 on which the pattern including the fourth region is formed, the first and second components are stacked by overlapping the first region and the third region with the stacked body. It can be explained that there is almost no error to the extent that the region and the fourth region overlap with each other in the stacked body. The error includes a manufacturing error that may actually occur. For example, the error may include an error within 100 μm, an error within 50 μm, an error within 30 μm, or an error within 10 μm.

As shown in FIG. 7 as an example, the multi-vision system can be introduced so as to be positioned below the first component 100 and the second component 200. The multivision system 13 may include, for example, the first vision camera 131, the second vision camera 132, and the total reflection lens 133 as described above. For example, as described above, the total reflection lens can transmit or refract light as it is without refraction depending on the angle of light incident on the total reflection lens, or can totally reflect light. .

Such a total reflection lens 133 is one example, as shown in FIG. 7, and the optical signal of the first vision camera 131 is refracted by the total reflection lens, and one of the first and second components. The optical signal of the second vision camera 132 can be installed so as to pass through the total reflection lens and reach the other component. Further, as shown in FIG. 7, the optical signal is refracted or transmitted at the same part of the total reflection lens, and the total reflection lens is installed so that the optical signal travels in the same direction. The same part of the first and second parts can be observed. The same part can be described with the meaning as described above.

The more the structure capable of confirming the arrangement of the first and second parts in the multi-vision system is similar to the laminated body of the first and second parts, the higher the precision of attaching the first and second parts. It is possible. The reason for this is that the structure capable of confirming the arrangement of the first and second parts can be confirmed in a more closely contacted state, and the minimum movement is maintained while maintaining the arrangement of the first and second parts. This is because the first and second parts can be attached. If the structure capable of confirming the arrangement of the first and second parts is a structure in which the first and second parts are separated by a predetermined distance or more, the arrangement of the first and second parts is accurately adjusted. Even in such a case, the arrangement of the first or second part may be detached in the initially set arrangement state during the process of attaching by moving the relative positions of the first and second parts. Therefore, the adhesion accuracy of the first and second parts may deteriorate.

One example of the multi-vision system 13 arranged and implemented as shown in FIG. 7 is a state in which the first part 100 and the second part 200 are arranged in a substantially closed structure on the attachment device in the driving state. The position can be identified. At this time, the separation distance between the first part and the second part having the closed structure is, for example, 10 mm or less, 9 mm or less, 8 mm or less, 7 mm or less, 6 mm or less, 5 mm or less, 4 mm or less, 3 mm or less, 2 mm or less or It can be 1 mm or less. Therefore, the accuracy of the first and second components can be improved using the multivision system.

In one example, the multi-vision system may further include illumination. The illumination 134 can serve to enable confirmation of the position of a part by a vision camera, for example. The illumination 134 can be installed to face the first and second vision cameras, for example, as shown in FIG.

In one example, the adhesion roller 14 may be installed so as to apply pressure to the stacked body of the first component 100 and the second component 200. At this time, the relative positions of the first and second parts may be changed so that the first and second parts are stacked on each other by the transfer unit, for example.

For example, as shown in FIGS. 3 and 5, the adhesion roller 14 can be installed in the second support portion 12. In one example, even if the adhesion roller 14 is in a state in which the adhesion device is not driven or in a state in which the adhesion device is driven, the adhesion roller 14 is separated from the holding base at a predetermined interval except when the first component and the second component are adhered. May be arranged in a separated state. However, the adhesion roller 14 moves so as to contact the holding table at the time when pressure is applied to the first and second parts, and can apply pressure in a state of contacting the holding table.

The attachment apparatus is an apparatus that attaches the first part and the second part to each other, and the attached first part and the second part are, for example, parts of an optical device that requires precise attachment. it can. In one example, one of the first part and the second part can be a liquid crystal panel, and the other can be an optical film. The optical film may be a polarizing plate, a retardation film, a protective film, or a stereoscopic image display optical filter.

In one example, the attachment device may be a manufacturing device of a stereoscopic image display device or may be a part of the manufacturing device.

In one example, a method of manufacturing a laminate of first and second parts with the deposition apparatus described above with reference to FIG. 8 will be described.

Referring to FIG. 8 as an example, the first component 100 can be positioned on a holding base (not shown) in which one or more holes are formed. The first component 100 may be fixed to the holding table of the first support part 11 in the suction process through the hole. In addition, the second component 200 can be fixed on the second support part 12. The method of fixing the second component 200 on the second support portion 12 is the same as the method of fixing the first component to the first support portion. The first part 100 fixed to the first support part 11 and the second part 200 fixed to the second support part 12 are moved relative to each other by a transfer part (not shown) and stacked on each other. Thus, a laminate can be provided.

At this time, the arrangement of the first and second components can be adjusted using the multivision system described above so that the stacked body is attached with high accuracy. Moreover, a pressure can be applied to the laminated body of the 1st and 2nd components using an adhesion roller so that the 1st and 2nd components may adhere favorably.

In one example, the first part may be formed with a pattern including a first area and a second area having different characteristics, and the second part may include a third area and a fourth area having different characteristics. The pattern containing it may be formed. For example, as described above, the first component can be a liquid crystal panel in which a pattern including the UR region and the UL region is formed, and the second component is a three-dimensional object in which the pattern including the FR region and the FL region is formed. It can be an optical filter for video display. That is, the first region of the liquid crystal panel is a UR region, the second region is a UL region, the third region of the stereoscopic image display optical filter is an FR region, and the fourth region is FL. Can be an area. Accordingly, the multi-vision system may check whether the UR region is matched with the FR region and the UL region is matched with the FL region in a state where the liquid crystal panel and the optical filter for stereoscopic image display are stacked on each other. it can. The matching means that the UR region exactly overlaps the FR region and the UR region does not overlap the FL region, but may include a manufacturing error that may occur substantially. The manufacturing error can be, for example, in the above-described range of 100 μm, 50 μm, 30 μm, or 10 μm.

If the matching is not accurate, the relative positions of the first and second parts can be adjusted so that the matching is accurate. Through such a process, the first and second parts can be attached with high accuracy. In one example, when the laminate is a stereoscopic image display device, the UR region and the FR region of the liquid crystal panel and the stereoscopic image display optical filter may exactly match, and the UL region and the FL region may exactly match. it can. Accordingly, the stereoscopic image display device manufactured by such a manufacturing method has a very low possibility of causing a cross-talk phenomenon and is excellent in the quality of the stereoscopic image.

In one example, confirming the images of the first and second parts by the multi-vision system can proceed in a closed configuration, as described above. Accordingly, the first and second parts can be stacked with a minimum amount of movement while the first and second parts are arranged to be matched.

The first and second components arranged by the multi-vision system can be stacked on each other while maintaining the arrangement. If the closing structure of the multi-vision system is driven with the first and second parts in contact, it may be omitted to adjust the relative positions of the first and second parts to be stacked on each other. it can.

The laminate of the first and second parts can be, for example, a laminate in which a normal pressure-sensitive adhesive and an adhesive are interposed between the first and second parts as described above. At this time, the first and second components can be adhered by applying pressure to the laminate of the first and second components using an adhesion roller.

Laminates attached to each other through such a process can be unloaded and produced as a product or introduced into a subsequent process.
