Description

Attachment

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

In a manufacturing process of a display device such as an LCD (Liquid Crystal Display) or another electronic product, a process of attaching two or more components to each other is often performed. Examples of such a process include 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 configure a stereoscopic image display device, as shown schematically in FIG. 1, an area for generating right eye and left eye video signals (hereinafter referred to as "R signal" and "L signal"). The split liquid crystal panel 100 and the optical filter 200 having a pattern for differently controlling the polarization states of the R and L signals should be attached. In the stereoscopic image display apparatus, a signal transmitted from an area generating the R signal of the liquid crystal panel 100 (hereinafter referred to as an “UR area”) controls an polarization state of an R signal of an optical filter (hereinafter referred to as “FR”. Area ”), and in which the signal transmitted from the area generating the L signal of the liquid crystal panel 100 (hereinafter referred to as the“ UL area ”) controls the polarization state of the L signal of the optical filter (hereinafter referred to as“ ul area ”). Hereinafter, the R signal and the L signal are separated and transmitted to the viewer via the "FL area". Therefore, it is required to attach the liquid crystal panel and the optical filter so that the UR region of the liquid crystal panel and the FR region of the optical filter match, and the UL region of the liquid crystal panel and the FL region of the optical filter match with high precision. If the UR region of the liquid crystal panel is attached to the FL region of the optical filter, the left eye of the R signal may be incident instead of the right eye. Accordingly, in the stereoscopic image display device, a crosstalk represented by a value of the percentage of the R signal incident to the left eye is increased based on the L signal incident to the left eye, resulting in difficulty in viewing a stereoscopic image. Therefore, in the case of a stereoscopic image display device, it is particularly required to manufacture using an attachment device capable of attaching a liquid crystal panel and an optical filter with high precision.

The present application provides an attachment device and a method of manufacturing a laminate using the same.

One embodiment of the present application is installed so that the first component is mounted, and the first component is mounted to the cradle in which one or more holes are formed and the first component is sucked through the hole when the first component is mounted on the cradle. A first support part including a fixing device installed to be fixed to the holder; A second support provided to fix the second component; And a transfer part provided to change a relative position of the first support part and the second support part so that the fixed first and second parts are stacked on each other.

In the present specification, the "installation of the first component to be mounted" means that the first component is installed to be mounted on the holder in the process of performing the attachment process. The attachment device may not include the first part. In addition, the meaning that it is "installed so that a 2nd component can be fixed" can also be interpreted similarly.

In this specification, the "first part", "second part", "first support part", and "second support part" are arbitrarily attached in order to demonstrate two parts and a support part. Therefore, the structure of the 1st component mentioned below may be located in a 2nd support part, or the structure of a 2nd component may be located in a 1st support part.

In one example, the second support may be installed to fix the second component by suction. For example, the second support part is installed such that the second part can be mounted like the first support part, and when the second part is mounted on the cradle with one or more holes formed therein, the second support part is sucked through the hole. It may include a fixing device that is installed to secure the second component to the cradle.

In one example, the suction force at the center of the first or second support is weaker than the edge to prevent the first or second component from sagging in the direction of the first or second support due to the suction force of the first or second support. I can regulate it.

In one example, the cradle includes a plurality of holes, and the density of the holes formed at the distal end of the cradle is formed in the center of the cradle to adjust the suction force at the center of the first or second support portion weaker than the edges. It may be higher than the density of the holes. Here, the density of holes means an area ratio of a plurality of holes per unit area. For example, if a plurality of holes all have the same area, the larger the density of the hole can be understood as the larger number of holes per unit area. Also, referring to FIG. 2, the distal end portion 1111 of the cradle is divided into three regions having the same area in the transverse direction, and divided into three regions having the same area in the transverse direction and positioned at the distal end. It can mean an area. Accordingly, the center portion 1112 of the holder may mean a region located in the center of the holder except for the distal end of the holder.

If the holder is a hole is formed it is possible to use a configuration used in the art without limitation. For example, the holder may use a mesh plate or the like.

In one example, the attachment device may be introduced with a multi vision system capable of identifying the positions of the first and second parts. For example, a multi-vision system may include a first vision camera installed to observe a state of a first part through an optical signal, a second vision camera installed to observe a state of a second part through an optical signal, and a total reflection lens. It may include. Here, the meaning of being able to observe the state of the part may be interpreted to mean that the position of the part may be identified.

The multi-vision system according to one example may be to enable the vision structure even in a closed structure in which the first part and the second part are substantially in close contact. In the closed structure, the separation distance between the first part and the second part 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, It may be 2 mm or less or 1 mm or less. In addition, since the adhesion accuracy of the first and second components can be improved as the first and second components are in close contact with each other, the lower limit of the separation distance between the first and second components in the closed structure is particularly limited. It is not limited and may be, for example, 0 cm or greater than 0 cm.

The total reflection lens may refer to a lens that can transmit or reflect light according to the incident angle of light. Specifically, the light incident on the total reflection lens may be transmitted as it is without refraction or may be transmitted by refracting or total reflection.

In one example, the total reflection lens may be installed such that the optical signal irradiated from the first vision camera or the optical signal irradiated from the second vision camera reaches the first or second component via the total reflection lens.

In addition, the total reflection lens, for example, one of the optical signal is transmitted through the total reflection lens to reach any one of the first and second components, the other signal is total reflection by the total reflection lens Or it may be installed to be refracted to reach the other one of the first and second parts. The signal passing through the total reflection lens and reaching the first or second component may be transmitted through the total reflection lens without refraction, or may be refracted and transmitted.

The optical signal passing through the total reflection lens and reaching either one of the first and second parts and the total reflection or refraction by the total reflection lens and reaching the other part of the first and second parts are first generated. A total reflection lens can be installed to reach the same site of the first and second parts.

Herein, the same part of the first and second parts is, for example, a virtual part penetrating through any part of the first part in a state where the first and second parts are arranged to overlap, and perpendicular to the penetrating surface of the first part. The site where the line touches the second part can be described as the same part as any part of the first part. However, in consideration of a substantial error, an area within 5 mm, within 3 mm, within 1 mm, or within 0.5 mm of the area where the imaginary line touches the second part may be included in the same area.

This multi-vision system allows the first and second parts to be stacked in a desired arrangement by observing the same portion of the first and second parts.

In one example, the total reflection lens includes a total reflection or refraction of a region through which one of the optical signals is transmitted and another optical signal so that the same region of the first and second components can be observed through the multi-vision system. It can be installed so that the site is the same.

In addition, the total reflection lens may be installed so that any one optical signal transmitted through the lens and the other optical signal totally reflected or refracted by the lens may travel in the same direction.

Therefore, the total reflection lens has the same area where any one signal is transmitted and the area where the other signal is totally reflected or refracted, and is installed so that the two signals travel in the same direction so that the same area of the first and second components is installed. 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 part.

In one example, the attachment device may further comprise an attachment roller installed to apply pressure to the laminate of the first and second parts stacked on each other by the transfer unit.

In one example, the first and second components can be attached by any method employed in the art. For example, the first and second parts can be attached by conventional adhesives or pressure-sensitive adhesives. Thus, in one example, the attachment roller may apply pressure to the laminate laminated with a conventional adhesive or adhesive interposed between the first and second components to enable attachment of the first and second components.

In one example, the first component may be a liquid crystal panel. Also, 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 the liquid crystal panel, but may be, for example, a polarizing plate, a retardation film, a protective film, and an optical filter for stereoscopic image display.

In one example, the first component may be a liquid crystal panel having UR and UL regions, and the second component may be an optical filter for displaying a stereoscopic image having FR and FL regions. Therefore, the attachment device may be, for example, part of a manufacturing apparatus of a stereoscopic image display apparatus or a manufacturing apparatus of a stereoscopic image display apparatus.

Another embodiment of the present application is to position the first component in the cradle in which one or more holes are formed, and to secure the first component to the cradle by suction through the hole, the fixed first component and the first A method of manufacturing a laminate of first and second parts comprising moving relative positions of the first and second parts such that the second parts fixed to the second support are stacked on each other.

In one example, the method of manufacturing the laminate of the first and second parts may be performed using the attachment device described above.

The second part can be fixed to the second support, for example by suction through suction.

In one example, in order to adjust the suction force at the center of the first or second support weaker than the edge, the suction force sucked through the hole at the distal end of the cradle can be adjusted to be greater than the suction force at the center of the cradle. As described above, the distal end and the central part of the holder may be understood with reference to FIG. 2.

In one example, the first component may have a pattern including first and second regions having different characteristics, and the second component may have a pattern including third and fourth regions having different characteristics. have. In addition, the lamination of the first and second components may be performed such that the first and third regions overlap in the laminate, and the second and fourth regions overlap in the laminate.

In one example, the first component may be a liquid crystal panel for displaying a stereoscopic image including an UR region as a first region and an UL region as a second region. In addition, the second component may be an optical filter for displaying a stereoscopic image including an FR region as a third region and an FL region as a fourth region. Accordingly, the stacking of the stereoscopic image display liquid crystal panel and the stereoscopic image display optical filter may be performed such that the UR region and the FR region overlap in the laminate, and the UL region and the FL region overlap in the laminate.

In one example, the method of manufacturing a laminate may further use a multi-vision system capable of identifying positions of the first and second parts in a state in which the first part and the second part form a closed structure.

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

In one example, the method of making a laminate may include applying pressure with an attachment roller to the laminate of the first and second parts. Further, for example, as described above, the laminate of the first and second parts may be one having a common adhesive or an adhesive between the first and second parts. Therefore, the laminate of the first and second parts in the state where the usual adhesive or the adhesive is interposed can be attached at the pressure applied by the attachment roller.

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

The exemplary attachment device of the present application can attach various parts with high precision. For example, the attachment device may provide a stereoscopic image display device which minimizes cross-talk by attaching a liquid crystal panel and an optical filter for stereoscopic image display with high precision.

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 to the embodiments shown below.

FIG. 3 schematically shows a side of an attachment device according to one embodiment, FIG. 4 shows a view of the same device as FIG. 3 from above, and FIG. 5 shows a view of the same device from FIG. 3 from below. It appeared. In FIG. 4, when the attachment device is observed from the top, since the first part 100 is not hidden by the first support part 11, the first part 100 is indicated by a dotted line to indicate its position. 5, since the second component 200 is not observed under the attachment device, the second component 200 is indicated by a dotted line. 3 to 5, the same reference numerals denote the same sites.

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. 3. 3 shows a state at one point in time of the attachment device. In FIG. 3, the first support 11 and the second support 12 are arranged to face up and down, but the first support 11 and the second support 12. The arrangement of the support 12 can be freely changed by the conveying part. In addition, as shown in FIG. 3, the attachment device may be a device having a multi-vision system 13 and having an attachment roller 14. As an example, as shown in FIG. 3, the multi vision system 13 and the attachment roller 14 may be embedded in the second support 12. In particular, in the case of the multi-vision system 13, it may be embedded in the first or second support to identify the position of the first and second parts of the closed structure. In this case, after identifying the attachment positions of the first and second components, it is possible to enter the attachment process immediately, thereby improving the attachment accuracy. However, the figure shown in FIG. 3 is only one example, and the position where the multi-vision system is introduced and the position where the attachment roller is mounted can be easily changed by the person skilled in the art.

With reference to FIG. 6 which is one example, the 1st support part of the said attachment apparatus is demonstrated. The first support part 11 may include a cradle 111 installed to allow the first component 100 or the like to be mounted thereon. The cradle 111 may be, for example, formed with one or more holes 113. The hole 113 of the holder 111 is exaggerated in the drawings, the actual hole 113 may be formed very narrow. For example, the holder may be installed using a mesh plate.

In addition, the first support part 11 may include a fixing device 112 capable of fixing the first component 100 by a suction process through a hole. In FIG. 6, the direction in which the gas is sucked into the fixing device 112 through the hole 113 of the holder 111 is indicated by an arrow. The first support part 11 of FIG. 6 includes a cradle 111 and a fixing device 112, and the lighting unit 134 is installed in a portion where the hole of the cradle 111 is not formed, thereby providing the first support part of FIG. 11) can be configured as.

The second support may fix the second component through various methods. Among them, the second support part may also be provided with a holder and a fixing device, for example, like the first support part, thereby fixing the second component on the second support part.

Although not shown in FIGS. 3 to 5, the transfer part is installed to change the relative positions of the first support part and the second support part, and it is possible to use a configuration employed in the art without limitation.

The multi vision system may enable the attachment device to attach the first and second components with high accuracy.

In one example, the high-precision attachment of the first and second components may include the first and second parts 100 having a pattern including the first and second areas having different characteristics, and the third and fourth different characteristics. In attaching the second component 200 in which the pattern including the region is formed, the stack of the first and second components includes the first region and the third region overlapping each other in the laminate, and the second region and the second component. It can be explained that there is little error in the degree to which the four regions overlap in the laminate. The error includes a manufacturing error that can actually occur, and may include, for example, an error within 100 μm, an error within 50 μm, an error within 30 μm, or an error within 10 μm.

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

As the total reflection lens 133 is an example of FIG. 7, the optical signal of the first vision camera 131 is refracted by the total reflection lens to reach one of the first and second components, and the second The optical signal of the vision camera 132 may be installed to pass through the total reflection lens as it is to reach another component. In addition, the optical signal can be refracted or transmitted through the same portion of the total reflection lens as shown in FIG. 7, and the total reflection lens can be installed to observe the same portion of the first and second components so that the optical signal proceeds in the same direction. Can be. The same site may be described in the meaning as described above.

It is possible to attach the first and second parts with higher precision as the structure capable of confirming the arrangement of the first and second parts with the multi-vision system is similar to that of the laminate of the first and second parts. The reason for this is that as the structure capable of confirming the arrangement of the first and second components is in close contact with each other, the first and second components can be moved with minimal movement while maintaining the arrangement of the first and second components. This is because it can be attached. If the structure capable of confirming the arrangement of the first and second components is a structure in which the first and second components are spaced more than a predetermined interval, the first and second components may be adjusted even if the arrangement of the first and second components is correctly adjusted. The arrangement of the first or second parts may be displaced in the initially set arrangement state during the process of moving the relative position of the parts. Therefore, the attachment precision of the 1st and 2nd components may worsen.

As an example, the multi-vision system 13 arranged and implemented as shown in FIG. 7 may be positioned even in a state in which the first component 100 and the second component 200 are placed in a substantially closed structure in an attachment device in a driving state. Identification is possible. At this time, the separation distance between the first part and the second part forming 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, or 3 mm or less. , 2 mm or less, or 1 mm or less. Therefore, the precision of the first and second components can be improved by using the multi vision system.

In one example, the multi vision system may be implemented by further including illumination. The lighting 134 may serve to enable positioning of parts due to, for example, a vision camera. In addition, the illumination 134 may be installed to face the first and second vision cameras, for example, as shown in FIG. 3.

In one example, the attachment roller 14 may be installed to apply pressure to the stack of the first component 100 and the second component 200. In this case, the first and second components may be in a state where the relative position is changed such that the first and second components are stacked on each other by the transfer unit, for example.

The attachment roller 14 may be included and installed in the second support 12 as shown in, for example, FIGS. 3 and 5. In one example, the attachment roller 14 may be disposed spaced apart from the cradle at predetermined intervals except when the first component and the second component are attached even when the attachment device is not driven or the attachment device is driven. Can be. However, the attachment roller 14 may move to contact the holder at the time when the pressure is applied to the first and second parts to apply pressure in contact with the holder.

The attachment device is a device for attaching the first component and the second component to each other, and the attached first component and the second component may be, for example, components of an optical device requiring precise attachment. In one example, either the first component or the second component may be a liquid crystal panel, and the other may be an optical film. In addition, the optical film may be a polarizing plate, a retardation film, a protective film or an optical filter for stereoscopic image display.

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

In one example, a method of manufacturing a stack of first and second parts with the attachment device described above with reference to FIG. 8 is described.

Referring to FIG. 8, one example, the first component 100 may be positioned on a holder (not shown) in which one or more holes are formed. The first component 100 may be fixed to a cradle of the first support part 11 by a suction process through the hole. Also, the second component 200 may be fixed on the second support 12. The manner in which the second component 200 is fixed on the second support 12 may be the same as the manner in which the first component is fixed to the first support. The first part 100 fixed to the first support part 11 and the second part 200 fixed to the second support part 12 are stacked by being stacked by moving their relative positions by a transfer part (not shown). Sieve can be provided.

At this time, the arrangement of the first and second components may be adjusted by using the aforementioned multi vision system so that the laminate may be attached with high accuracy. It is also possible to apply pressure to the stack of first and second parts using attachment rollers so that the first and second parts can be attached well.

In one example, the first component may have a pattern including a first region and a second region having different characteristics from each other, and the second component may have a pattern including a third region and a fourth region having different characteristics. Can be. For example, the first component may be a liquid crystal panel having a pattern including the UR region and the UL region as described above, and the second component may be an optical filter for displaying a stereoscopic image having a pattern including the FR region and the FL region. Can be. That is, the first region of the liquid crystal panel may be an UR region, the second region may be an UL region, the third region of the optical filter for displaying a stereoscopic image may be an FR region, and the fourth region may be an FL region. Accordingly, the multi-vision system can check whether the UR region matches the FR region and the UL region matches the FL region while the liquid crystal panel and the optical filter for stereoscopic image display are stacked on each other. The matching means that the UR region exactly overlaps the FR region, and that the UR region does not overlap the FL region, but may include a manufacturing error that may occur substantially. The manufacturing error can be in the range of, for example, within 100 μm, within 50 μm, within 30 μm or within 10 μm.

If the matching is not correct, the relative positions of the first and second components can be adjusted to make the matching accurate. Through this process, the first and second parts can be attached with high precision. For example, when the laminate is a stereoscopic image display device, the UR region and the FR region of the liquid crystal panel and the optical filter for stereoscopic image display may exactly match, and the UL region and the FL region may exactly match. Accordingly, the stereoscopic image display device manufactured by the manufacturing method is very unlikely to cause crosstalk, and thus the stereoscopic image quality is excellent.

In one example, the identification of the phases of the first and second parts by the multi-vision system can proceed in a closed structure as described above. Thus, the first and second parts can be stacked with minimal movement with the first and second parts arranged to match.

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

The laminate of the first and second components may be, for example, a laminate of a common adhesive and an adhesive interposed between the first and second components as described above. At this time, the first and second components can be attached by applying pressure to the laminate of the first and second components using an attachment roller.

Through this process, the laminates attached to each other may be unloaded to produce a product or introduced into a subsequent process.
