Description

Attaching Device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attaching apparatus 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 other electronic products, a process of attaching two or more components to each other is often performed. Examples of such a process include a case of attaching an optical film such as a polarizing film or a retardation film to a panel of an LCD. In addition, for example, in order to construct a stereoscopic image display apparatus, as schematically shown in Fig. 1, a region for generating right and left eye image signals (hereinafter referred to as "R signal" and "L signal" It is necessary to attach the optical filter 200 formed with the divided liquid crystal panel 100 and a pattern for controlling the polarization state of the R and L signals differently. The stereoscopic image display device displays a region (hereinafter referred to as " FR ") in which a signal transmitted from a region (hereinafter referred to as " UR region ") of the liquid crystal panel 100, (Hereinafter, referred to as " UL region ") in which the L signal of the liquid crystal panel 100 is generated (hereinafter referred to as " Hereinafter referred to as " FL region "), the R signal and the L signal are separated and transmitted to the viewer. Therefore, it is required that the liquid crystal panel and the optical filter are attached so that the UR region of the liquid crystal panel matches the FR region of the optical filter, and the UL region of the liquid crystal panel and the FL region of the optical filter match with high accuracy. If there is a portion where the UR region of the liquid crystal panel adheres to the FL region of the optical filter, the R signal may be incident on the left eye, not the right eye. Therefore, there is a problem that it becomes difficult to view the stereoscopic image because the crosstalk indicated by the value of the percentage of the R signal incident on the left eye is increased based on the L signal incident on the left eye in the stereoscopic image display apparatus. Therefore, in the case of the stereoscopic image display apparatus, it is required to manufacture the liquid crystal panel and the optical filter using an attaching apparatus capable of attaching the liquid crystal panel and the optical filter with high precision.

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

One embodiment of the application includes a first support configured to secure a first component; A second support portion including a pressure-sensitive adhesive pad capable of securing a second component; And a transfer unit installed to change the relative positions of the first and second support units so that the first and second parts fixed to the first and second support units are stacked on each other.

Means that the attachment device is provided so as to be capable of fixing the first part to the first support part in the course of performing the attachment process, and the term " May not include the first component. The " pressure-sensitive adhesive pad capable of securing the second component "

In the present specification, the "first part", the "second part", the "first support part" and the "second support part" are arbitrarily numbered to describe the two parts and the support part. Therefore, it is also possible that the structure of the first part described below is located in the second support part, or the structure of the second part is located in the first support part.

In one example, the support of either of the first and second supports may be to secure the component using a pressure sensitive adhesive pad. In this specification, for example, a support using a pressure-sensitive adhesive pad may be referred to as a second support.

In one example, the pressure sensitive adhesive pad may comprise a support layer and a pressure sensitive adhesive layer formed on one side of the support layer. The surface of the pressure-sensitive adhesive layer may be, for example, a position where the first or second component is loaded.

The support layer may be, for example, a substrate for forming the pressure-sensitive adhesive layer. In one example, the substrate may be a transparent polymer substrate, an opaque polymer substrate, glass, or the like. Among them, for example, a transparent polymer substrate can be used to observe the arrangement of parts by a multivision system described later. Examples of such a substrate include a polyurethane base, a polyester base such as PET (poly (ethylene terephthalate)), an acrylic base, and the like.

The pressure-sensitive adhesive layer can be adhered to the pressure-sensitive adhesive layer by applying a predetermined pressure to the first or second component, and a structure known in the art can be suitably employed. For example, the pressure-sensitive adhesive layer may be a porous polymer layer or a pressure-sensitive adhesive layer.

The porous polymer layer may be, for example, a material used for fixing glass in a glass factory or the like. In the above-described material, a plurality of voids are formed therein, and voids may exist on the surface to which the adherend is attached. If an adherend, for example, a plate-like part, is placed on such a material under an appropriate pressure, a vacuum is formed by the gap formed in the material, so that even if there is no separate suction process, . As such a porous polymer layer, it is possible to use without limitation those used in the art. For example, foamed polyester or the like may be used as the porous polymer layer. The foamed polyester can be produced by various methods known in the art. For example, a polyester resin to which a tetracarboxylic dianhydride is added may be first fed into an extruder and melted at a temperature of about 200 ° C. The blowing agent may then be introduced into the molten mixture through an opening in the inlet of the extruder to produce a foamed polyester. As the polyester resin, for example, a resin obtainable by condensation polymerization reaction of an aromatic dicarboxylic acid with a diol compound can be used. Specifically, examples of the aromatic dicarboxylic acid include terephthalic acid, isophthalic acid, naphthalenecarboxylic acid and diphenyl ether dicarboxylic acid. Examples of the diol compound include ethylene glycol, tetraethylene glycol, cyclohexanedimethanol and 1,4-butanediol. As the foaming agent, a liquid or a pyrolyzable compound which can be easily vaporized can be used. As the foaming agent, for example, an inert gas such as carbon dioxide may be used. As an extruder capable of producing a foamed polyester by using a polyester resin and a foaming agent, those used in the art can be used without limitation. For example, as the extruder, a single screw, a double-head screw, a composite screw or the like may be used.

The pressure-sensitive adhesive layer may be, for example, a material having viscoelasticity. Such a material may have a substantially permanent viscosity at room temperature. The material having viscoelasticity can be a material which can be adhered to a material by light pressure and can be adhered by pressure simply without activity by heat, water or solvent. The pressure-sensitive adhesive layer exhibits a strong holding force when the adherend is adhered in a state in which a proper pressure is applied, and when the adherend is removed, the pressure-sensitive adhesive layer is removed without residue and can retain cohesive force and elasticity. When the pressure-sensitive adhesive layer is used as the pressure-sensitive adhesive layer in this way, the component can be fixed simply by placing an appropriate pressure on the pressure-sensitive adhesive layer. As the constitution of such a pressure-sensitive adhesive layer, a known constitution known in the pressure-sensitive adhesive field can be suitably employed. Examples of the pressure-sensitive adhesive layer include a pressure-sensitive adhesive layer made of natural rubber, synthetic rubber, vinyl chloride / vinyl acetate copolymer, polyvinyl alkyl ether, polyacrylate or modified polyolefin adhesive and a curing agent such as isocyanate added thereto .

When the pressure-sensitive adhesive layer of the above-described type is used, since the suction process is not required in the fixing process, the fixing can be performed while maintaining the flatness of the component. Thus, it is possible to prevent the occurrence of curl or wave of the component, and it is possible to ensure tolerance to the flexural characteristics of the component. In one example, the part secured through the pressure-sensitive adhesive pad can be a plate or sheet-like curl or wave that can easily occur.

In one example, when the component is fixed using the pressure-sensitive adhesive pad as described above, components of various sizes can be effectively attached. Therefore, it is possible to improve work productivity of the attaching device.

In one example, the first support can be installed to hold the first component in an adsorption manner through suction. For example, the first support part may be installed so that the first part can be mounted, and when the first part is mounted on the cradle, the first part is inserted into the cradle through the hole, As shown in FIG.

In one example, the suction force at the center of the first support portion may be adjusted to be weaker than the edge to prevent the first component from sagging toward the first support portion due to the suction force of the first support portion.

In one example, in order to adjust the suction force at the center of the first support part to be weaker than the edge, the holder includes a plurality of holes, and the density of the holes formed at the distal end of the holder is smaller than the density of holes formed at the center of the holder. It can be high. Here, the density of holes means an area ratio of a plurality of holes per unit area. For example, if a plurality of holes are all going to have the same area, it can be understood that the number of holes per unit area is large when the density of holes is large. Referring to FIG. 2, the distal end portion 1111 of the cradle is divided into three regions having the same area in the lateral direction and divided into three regions having the same area in the longitudinal direction, It can mean area. Accordingly, the central portion 1112 of the cradle may be located at the center of the cradle except the distal end of the cradle.

As long as the holder is provided with a hole, it is possible to use the constitution used in the art without limitation. For example, a mesh plate or the like can be used as the cradle.

In one example, the first support may include a pressure sensitive adhesive pad, such as a second support, to secure the first component. Herein, the pressure-sensitive adhesive pad included in the first support portion may have the structure described above.

In one example, a multivision system capable of identifying the location of the first and second components may be introduced into the attachment device. For example, the multivision system includes a first vision camera installed to observe the state of the first component through an optical signal, a second vision camera installed to observe the state of the second component through the optical signal, and a total reflection lens . Here, the meaning of observing the state of the part can be interpreted as meaning that the position of the part can be identified.

A multivision system according to one example may be one that enables a vision structure in a closed configuration where the first and second components are in close contact. The distance between the first component and the second component in the closed structure may be, 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, 2 mm or less or 1 mm or less. In addition, since the first part and the second part are in close contact with each other, the attachment accuracy between the first part and the second part can be improved. Therefore, the lower limit of the separation distance between the first part and the second part But may be, for example, 0 cm or greater than 0 cm.

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

In one example, the total reflection lens may be installed such that 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 via the total reflection lens.

Further, the total reflection lens may be configured such that, for example, any one of the optical signals passes through the total reflection lens to reach any one of the first and second components, and the other signal reaches the total reflection lens Or may be refracted to reach the other one of the first and second parts. A signal transmitted through the total reflection lens and reaching the first or second component may transmit the total reflection lens as it is without refraction or may be refracted and transmitted.

An optical signal transmitted through the total reflection lens and arriving at any one of the first and second components and an optical signal reaching any one of the other components of the first and second components due to total reflection or refraction by the total reflection lens, 1 and the total area of the second component.

Here, the same part of the first and second parts means, for example, a first part and a second part which are arranged so as to overlap with each other and which pass through any one part of the first part, The portion where the wire contacts the second component can be described as the same portion as any one portion of the first component. 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 the portion where the imaginary line touches the second component may be included in the same portion.

By observing the same part of the first and second parts through the multivision system, the first and second parts can be stacked in a desired arrangement.

In one example, the total reflection lens may be configured so that one part of the optical signal, which is different from the part through which the optical signal is transmitted, is totally reflected or refracted so that the same part of the first and second parts can be observed through the multi- Can be installed in the same position.

Also, the total reflection lens may be installed such that any one optical signal transmitted through the lens and another optical signal totally reflected or refracted by the lens proceed in the same direction.

Therefore, it is preferable that the total reflection lens has the same portion in which one signal is transmitted and the other signal is totally reflected or refracted, and the two signals proceed in the same direction so that the same portion of the first and second components 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 portion. In this case, the first or second support portion can be installed so as to be able to be photographed by the vision camera.

In one example, the first and second vision cameras and the total reflection lens may be installed inside the first support part. In one example, the first support may be one that is capable of securing the part using a suction system that includes the above-described stand and the fixture. In this case, the cradle may use a mesh-type plate, and the first and second vision cameras and the total reflection lens may be positioned on the back surface of the mesh-type plate. Accordingly, the first and second vision cameras can photograph the positions of the first and second components through the holes of the mesh-type plate. Further, in another example, the first support portion may be one capable of fixing the component using the pressure-sensitive adhesive pad described above. In this case, the supporting layer of the pressure-sensitive adhesive pad and the pressure-sensitive adhesive layer may be made of a material having overall light transmittance. However, the present invention is not limited thereto, and if the pressure-sensitive adhesive pad is made of an opaque or semi-transparent material, at least a part of the pad may be made of a transparent material. In the present specification, a certain region constituted by such a transparent material may be referred to as a vision region. In one example, as shown in FIG. 3, the pressure sensitive adhesive pad may have a vision area 100 formed thereon. The method of forming the vision area on the pressure-sensitive adhesive pad is not particularly limited. For example, a transparent material having a thickness similar to that of the pad may be disposed on the pad.

In one example, the pressure-sensitive adhesive pad included in the second support portion may have optical transparency, such as a pressure-sensitive adhesive pad that may be included in the first support portion, or may have a vision region.

In one example, the adhering apparatus may further include an attaching roller provided so as to apply pressure to the laminated body of the first and second parts stacked on each other by the conveying section.

In one example, the first and second components may be attached by a manner employed in the art. For example, the first and second components may be attached by conventional adhesives or adhesives. Thus, in one example, the attachment roller may apply pressure to the stacked laminate with the usual adhesive or tackifier interposed between the first and second components to enable the first and second components to be attached.

In one example, the first component may be a liquid crystal panel or the like. Further, in one example, the second component may be an optical film or the like. The optical film may be a polarizing plate, a retardation film, a protective film, an optical filter for stereoscopic image display, or the like, as long as it can adhere to a liquid crystal panel.

Although not particularly limited, in the case of attaching the optical film and the liquid crystal panel in one example, the optical film may be fixed using a pressure-sensitive adhesive pad. This is because, when the component is fixed using the pressure-sensitive adhesive pad, it is possible to prevent the component from being curled or wave as described above. In the case of a liquid crystal panel, it may be fixed to the support by a suction process or a method using a pressure-sensitive adhesive pad. In the case of a liquid crystal panel, it can be fixed to the supporting portion by other methods.

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

Another embodiment of the present application relates to a pressure sensitive adhesive pad comprising a pressure sensitive adhesive pad having a second component positioned on a pressure sensitive adhesive pad and a pressure applied to the second component to secure the pressure sensitive adhesive pad to a second support, And moving the relative positions of the first component and the second component so that the first component and the second component are stacked on each other.

In one example, the method of producing the laminate of the first and second parts can be carried out using the above-described attaching device.

The first component may be secured to the first support by, for example, suction through suction.

In one example, the suction force at the center of the first support portion may be adjusted to be weaker than the edge to prevent the first component from sagging toward the first support portion due to the suction force of the first support portion.

In one example, in order to adjust the suction force at the center of the first support portion to be weaker than the edge, the suction force sucked through the hole at the distal end of the mount can be adjusted to be larger than the suction force at the center portion of the mount. The distal end and the central portion of the cradle can be understood with reference to Fig. 2 as described above.

However, the first component may be fixed to the first support in a manner other than the above-described manner. For example, the first component may be secured to the first support using a pressure sensitive adhesive pad.

In one example, a pattern including first and second regions having different characteristics from each other is formed on the first component, and a pattern including third and fourth regions having different characteristics from each other may be formed on the second component have. Further, the lamination of the first and second parts may be performed such that the first and third regions are overlapped in the laminate, and the second and fourth regions are overlapped in the laminate.

In one example, the first component may be a liquid crystal panel for a stereoscopic image display including a UR region as a first region and a UL region as a second region. The second component may be an optical filter for stereoscopic image display including an FR region as a third region and an FL region as a fourth region. Therefore, the lamination of the liquid crystal panel for stereoscopic image display and the optical filter for stereoscopic image display may be performed such that the UR region and the FR region are overlapped in the laminate, and the UL region and the FL region are overlapped in the laminate.

In one example, a method of manufacturing a laminate may further include a multivision system capable of identifying the positions of the first and second components in a state where the first component and the second component form a closed structure.

The multivision system may be driven by, for example, a first vision camera, a second vision camera, and a total reflection lens as described above. That is, the total reflection lens may be provided such that the optical signal irradiated from the first or second vision camera reaches the first or second component through the total reflection lens. The method of driving the multivision system can be performed in the same manner as described above.

In one example, a method of making a laminate can include applying pressure to the laminate of the first and second components with an attachment roller. In addition, for example, as described above, the laminated body of the first and second parts may include a normal pressure-sensitive adhesive or an adhesive between the first and second parts. Therefore, the laminate of the first and second parts in a state in which the ordinary adhesive or the pressure-sensitive adhesive is interposed can be adhered with the pressure applied by the attaching roller.

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

Exemplary attachment devices of the present application are capable of attaching various components with high precision. For example, the adhering apparatus can provide a stereoscopic image display device in which a liquid crystal panel and an optical filter for stereoscopic image display are attached with high precision to minimize a cross-talk phenomenon.

Embodiments of the present application will now be described with reference to FIGS. 4 through 6, but the scope of the present application is not limited by the embodiments shown below.

Figure 4 schematically illustrates a side view of an attachment device according to one embodiment, Figure 5 shows a view from above of the same device as Figure 4, Figure 6 shows the same device as Figure 4 observed from below . 5, when the attachment device is viewed from above, the first part 100 is not visible from the first support part 11, so that the first part 100 is indicated by a dotted line and its position is indicated. Also in FIG. 6, since the second part 200 is not observed in the lower part of the attaching device, the second part 200 is indicated by a dotted line. 4 to 6, the same reference numerals denote the same parts.

In one example, the attachment device may include a first support portion 11, a second support portion 12, and a transfer portion (not shown) as shown in FIG. 4, the first supporting part 11 and the second supporting part 12 are arranged to face up and down, but the first supporting part 11 and the second supporting part 12 The arrangement of the support portions 12 can be freely changed by the conveying portion. 4, the attachment device may be a device having a multivision system 13 introduced therein and having an attachment roller 14. [ 4, the multivision system 13 and the attachment roller 14 may be embedded in the second support portion 12. In this case, In particular, in the case of the multivision system 13, it may be embedded in the first or second support part to identify the positions of the first and second parts of the closed structure. In this case, it is possible to directly enter the attaching process after the attachment positions of the first and second parts are identified, so that the attachment accuracy can be improved. However, the shape shown in Fig. 4 can be easily changed by a person skilled in the art, for example, the position where the multi-vision system is introduced and the position where the attachment roller is mounted.

Referring to Figs. 7 and 8 which are one example, the first or second support portion of the attachment device will be described.

The support portion of any one of the first and second support portions included in the attaching device may include a pressure-sensitive adhesive pad capable of fixing the component. For example, the second support portion 12 may include a pressure-sensitive adhesive pad 121 that can fix the second component 200. In one example, the pressure-sensitive adhesive pad 121 may include a support layer 1211 and a pressure-sensitive adhesive layer 1212 disposed on the support layer, as shown in FIG. The pressure-sensitive adhesive layer 1212 can be adhered when the components are brought into contact with each other under a predetermined pressure. For example, the pressure-sensitive adhesive layer 1212 may be the above-described porous polymer layer or pressure-sensitive adhesive layer.

In one example, the first support may also include a pressure sensitive adhesive pad to secure the first component. In this case, the pressure-sensitive adhesive pad of the first support portion may be configured in the same manner as the pressure-sensitive adhesive pad included in the second support portion.

In another example, the first support may be capable of fixing the first component by a suction method including the above-described stand and the fixing device. Referring to Fig. 8, which is one example, the first supporting portion using the suction method will be described. The first support part 11 may include a mount 111 installed to mount the first part 100 and the like. The holder 111 may be formed with at least one hole 113, for example. The holes 113 of the holder 111 are shown in an exaggerated form in the drawing, and the actual holes 113 can be formed very narrowly. For example, the cradle can be installed using a mesh-type plate.

In addition, the first support 11 may include a fastening device 112 that can secure the first part 100 in a suction process through the hole. 8, the arrow indicates the direction in which the gas is sucked into the fixing device 112 through the holes 113 of the cradle 111. As shown in FIG. 8 includes a cradle 111 and a fixing device 112. A light 134 is provided on a portion of the cradle 111 on which no hole is formed so that the first supporting portion 11 11).

The transfer portion is not shown in FIGS. 4 to 6, but is provided to change the relative positions of the first and second support portions, and it is possible to use any configuration adopted in the art without limitation.

The multivision system can allow the attachment device to attach the first and second parts with high precision.

In one example, the attachment of the first and second components with high accuracy is achieved by forming a third region having a different characteristic from the first region 100 having a pattern including the first region and the second region having different characteristics from each other, The first and second regions are stacked such that the first region and the third region are overlapped in the stacked body, and the second region and the third region overlap each other, It can be explained that there is little error in the degree of overlap of the four regions in the laminate. The error includes actual manufacturing errors that may actually occur, and may include, for example, an error within 100 占 퐉, an error within 50 占 퐉, an error within 30 占 퐉, or an error within 10 占 퐉.

9, the multivision system may be introduced to be positioned below the first part 100 and the second part 200. [0051] As shown in FIG. The multivision system 13 may include a first vision camera 131, a second vision camera 132, and a total reflection lens 133, for example, as described above. The total reflection lens can transmit or refract the light without refraction and transmit it, or totally reflect the light, according to the angle of the light incident on the total reflection lens as described above.

9, an optical signal of the first vision camera 131 is refracted by the total reflection lens to reach any one of the first and second parts, and the second The optical signal of the vision camera 132 may be installed so as to penetrate the total reflection lens as it is and reach the other component. Further, the optical signal may be refracted or transmitted through the same part of the total reflection lens as shown in FIG. 9, and a total reflection lens may be installed so that the optical signals proceed in the same direction to observe the same part of the first and second parts . The same portion can be described in the same manner as described above.

It is possible to attach the first and second parts with high accuracy as the structure in which the arrangement of the first and second parts can be confirmed by the multivision system is similar to the structure of the laminate of the first and second parts. The reason for this is that as the structure for confirming the arrangement of the first and second parts can be confirmed in a state in which they are in closer contact with each other, the first and second parts can be moved with minimum movement while maintaining the arrangement of the first and second parts Because it can be attached. If the structure in which the arrangement of the first and second parts is confirmed is a structure in which the first and second parts are separated from each other by a predetermined distance or more, even if the arrangement of the first and second parts is correctly adjusted, The arrangement of the first or second component may be released in an initially set state during the process of moving and attaching the relative position of the component. Therefore, the attachment accuracy of the first and second parts can be deteriorated.

The multivision system 13, which is implemented as an example of FIG. 7, can be installed in a state where the first component 100 and the second component 200 are placed in a substantially closed structure, Identification is possible. The distance between the first part and the second part constituting the closed structure is, for example, less than 10 mm, less than 9 mm, less than 8 mm, less than 7 mm, less than 6 mm, less than 5 mm, less than 4 mm, less than 3 mm , 2 mm or less, or 1 mm or less. Accordingly, the accuracy of the first and second components can be improved by using the multivision system.

In one example, the multivision system may be implemented with additional illumination. The illumination 134 may serve, for example, to enable positioning of the part due to the vision camera. In addition, the illumination 134 may be installed to face the first and second vision cameras, for example, as shown in FIG.

In one example, the attachment roller 14 may be installed to apply pressure to the laminate of the first component 100 and the second component 200. At this time, the first and second parts may be in a state in which the relative positions are changed so that the first and second parts are stacked on each other, for example, by the conveying part.

The attachment roller 14 may be installed in the second support portion 12 as shown in FIGS. 4 and 6, for example. In one example, the attaching roller 14 is disposed in a state of being apart from the pressure-sensitive adhesive pad at a predetermined interval except when the first component and the second component are attached, . However, at the time of applying pressure to the first and second parts, the attaching roller 14 may move to contact the back surface of the pressure-sensitive adhesive pad and apply pressure to the back surface of the pressure-sensitive adhesive pad.

The attaching device is a device for attaching the first part and the second part to each other, and the first part and the second part to be attached may be parts of an optical device requiring precise attachment, for example. 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. 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 laminate of first and second parts with the above-described attachment device with reference to Fig. 10 will be described.

Referring to FIG. 10, which is an example, the first part 100 can be positioned on the first support part 11. FIG. In one example, the first component 100 may be secured to the first support 11 in a suction process or may be secured using a pressure sensitive adhesive pad. Also, the second component 200 can be fixed on the second support portion 12 as well. The manner in which the second part 200 is fixed on the second support part 12 may be, for example, a method using a pressure-sensitive adhesive pad. 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 due to the transfer part (not shown) Sieve can be provided.

At this time, the arrangement of the first and second parts can be adjusted using the above-described multivision system so that the laminate can be attached with high accuracy. In addition, pressure can be applied to the laminated body of the first and second parts by using the attaching roller so that the first and second parts can be adhered 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 be one having a pattern including a third region and a fourth region having different characteristics . For example, the first part may be a liquid crystal panel having a pattern including the UR area and the UL area as described above, and the second part may be an optical filter for stereoscopic image display in which a pattern including the FR area and the FL area is formed . That is, the first area of the liquid crystal panel is the UR area, the second area is the UL area, the third area of the stereoscopic image display optical filter is the FR area, and the fourth area is the FL area. Therefore, in the multi-vision system, it is possible to confirm whether the UR area is matched with the FR area and the UL area matches the FL area in a state where the liquid crystal panel and the optical filter for stereoscopic image display are laminated to each other. The matching means that the UR region exactly overlaps with the FR region and the UR region does not overlap with the FL region, but may include manufacturing errors that may actually occur. The manufacturing error may be, for example, within the range of 100 占 퐉, within 50 占 퐉, within 30 占 퐉, or within 10 占 퐉 described above.

If the matching is not correct, the relative position of the first and second components can be adjusted so that the matching is accurate. Through this process, the first and second parts can be attached with high precision. In one example, when the laminate is a stereoscopic image display device, the UR area and the FR area of the liquid crystal panel and the stereoscopic image display optical filter match exactly, and the UL area and the FL area can be exactly the same. Therefore, the stereoscopic image display device manufactured by such a manufacturing method is very unlikely to cause a cross-talk phenomenon, and therefore, the stereoscopic image quality is excellent.

In one example, identifying the phases of the first and second components by the multivision system may proceed in a closed configuration as described above. Thus, the first and second parts can be stacked with minimal movement in a state in which the first and second parts are arranged to be matched.

The first and second parts arranged by the multivision system can be stacked on each other while maintaining the arrangement state. If the closed structure of the multivision system is driven in a state in which the first and second components are in contact, adjusting the relative positions of the first and second components so that they are laminated to each other may be omitted.

The laminate of the first and second parts may be, for example, a laminate in which a conventional adhesive and an adhesive are interposed between the first and second parts as described above. At this time, the first and second parts can be attached by applying pressure to the laminated body of the first and second parts using the attachment rollers.

The laminate attached to each other through this process can be unloaded to be produced as a product or introduced into a subsequent process.
