Connecting device

The priority of the present application is back to the Korean Patent No. 2011-0077983 filed on August 5, 2011, and the Korean Patent No. 2012-0083047 filed on Jan. 30, 2012, to the Korean Patent Office. The contents disclosed in this case are all incorporated into this case for reference.

The present invention relates to a connecting device and a method of manufacturing a laminate using the same.

In the manufacturing process of a display device, such as a liquid crystal display or other electronic product, it is often necessary to perform a connection process of two or more components. An example of such a process may be for connecting an LCD panel and an optical film to each other, such as a polarizing film or a retardation film. For example, as schematically shown in FIG. 1, in order to construct a 3D image display device, regions (1001, 1002) of right eye signals and left eye signals are generated on the liquid crystal panel 100 (hereinafter referred to as "R signals" and "L signals". The pattern is separately formed thereon, and patterns for differentially adjusting the polarization states of the R signal and the L signal are formed on the optical filter 200, and the optical filters 200 should be connected to each other. In the 3D video display device, the signal transmitted from the region 1001 (hereinafter referred to as "UR region") in which the R signal is generated from the liquid crystal panel 100 is adjusted by the optical filter to adjust the polarization state of the R signal 2001 (hereinafter referred to as "FR region"). . Similarly, the signal transmitted from the region 1002 (hereinafter referred to as "UL region") for generating the L signal from the liquid crystal panel 100 passes. The optical filter adjusts the region 2002 of the polarization state of the L signal (hereinafter referred to as "FL region"), and the R signal and the L signal are separated from each other and then reach the observer. Therefore, it is required that the liquid crystal panel and the optical filter are connected to each other such that the UR region and the filter FR region are matched to each other, and the UL region is highly accurately matched with the FL region of the optical filter. If a portion of the UR area of the liquid crystal panel is connected to the FL area of the optical filter, the R signal cannot enter the right eye but enters the left eye. Therefore, crosstalk means that in the 3D video device, the percentage of the R signal entering the left eye relative to the signal entering the left eye L is increased, making it difficult for the viewer to view the 3D image. Therefore, in the process of manufacturing a 3D display device, it is necessary to utilize a connecting device that can highly accurately connect the liquid crystal panel and the optical film to each other.

The present invention provides a joining device and a method of manufacturing a laminate using the same.

One embodiment of the present invention provides a connecting device including a first support portion including a support piece for holding a first member and having at least one hole formed therein, and a fixing device when the first member is held When the support piece is on the support piece, the hole is fixed to the support piece through the suction process; a second support part is used for fixing a second component thereon; and a transmission part is used for controlling the first support part and the first support part The relative positions of the two supporting portions are such that the first member is fixed to the first supporting portion and the second member is fixed to the second supporting portion and stacked on each other.

In the present specification, the expression "installed to keep the first member can be held" means that the first member can be held on the first support portion when the connecting device performs a joining process. The connecting device that is not in operation may not include the first component. Further, the expression "installed to hold the second component" may have the same meaning.

The terms "first element", "second element", "first support portion" and "second support portion" used in the present specification are arbitrarily set to describe two elements and two support portions. . Thus, the first element can be placed on the second support and the second element can be placed on the first support.

In an embodiment, the second support portion can fix the second member to the second support portion by suction. Like the first support portion, for example, the second support portion may include a support piece for holding the second member thereon and having at least one hole formed thereon, and including when the second member is retained on the support piece A fixing means for securing the second member to the support sheet by the suction process.

In an embodiment, in order to prevent the first and second members from being deflected toward the first or second support portion due to the suction of the first or second support portion, the suction at the center of the first or second support portion is adjustable Is less than the suction at the edge.

In an embodiment, in order to adjust the suction at the center of the first or second support portion to be smaller than the suction at the edge, the support piece includes a plurality of holes, and the density of the holes formed on the edge of the support piece may be greater than the center of the support piece. The density of the holes. Here, the density of a pore refers to a surface area ratio of a plurality of pores per unit surface area. For example, it can be understood that if the holes formed on the edge of the support piece and the center of the support piece have the same surface area, the high density hole is indicated in Many holes are formed in the unit area. Further, referring to FIG. 2, when the entire area of the support piece is divided into three areas having the same area in the transverse direction and is divided into three areas having the same area in the longitudinal direction, the edge 1111 of the support piece Can refer to an area on the edge. Thus, the center 1112 of the support sheet can refer to the area at the center of the support sheet in addition to the edge of the support sheet.

If the support sheet has a hole formed therein, the structure used in the art can be employed without any limitation. For example, a mesh plate can be used as the support sheet.

In an embodiment, the attachment device can provide a multi-vision system that can identify the position of the first and second components. For example, the multiple vision system can include a first vision system for viewing the state of the first component through the optical signal, a second vision system for viewing the state of the second component through the optical signal, and a total reflection lens. Here, the meaning of "observing the state of the component" can be interpreted as "identifying the position of the component".

A multiple vision system in accordance with an embodiment may construct a visual structure in which the first component and the second component are disposed in a substantially closed configuration. In the closed structure, for example, the distance between the first element and the second element may be 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. Furthermore, if the first element and the second element are placed closely, the degree of connection of the first and second elements can be increased to such an extent that the first and second elements are in the closed structure. There is no limit to the lower limit between the distances. For example, the distance between the first and second elements can be 0 (zero) or more.

The total reflection lens may be a lens through which light passes, or a lens that is completely reflected by light, depending on the angle of incidence. In particular, light input to the total reflection lens may pass through the total reflection lens without refraction, or may be refracted first and then passed through the total reflection lens, or may be totally reflected by the total reflection lens.

In an embodiment, the total reflection lens may be arranged to allow an optical signal emitted from the first visual camera or an optical signal emitted from the second visual camera to pass through the total reflection lens and then to the first element or the second element.

For example, the total reflection lens can be arranged such that one of the optical signals can pass through the total reflection lens and reach one of the first and second elements, while the other signals are completely reflected or refracted by the total reflection lens and then reach the first and second elements. Another one. The signal passing through the total reflection lens and reaching the first element or the second element may be transmitted without refraction transmission or refraction.

The total reflection lens may be arranged such that the optical signal passing through the total reflection lens and reaching one of the first and second elements, and the optical signal totally reflected or refracted by the total reflection lens and then reaching the other of the first and second elements The same position of the first and second components can be reached.

Here, regarding the same position of the first and second elements, in a state in which the first element and the second element are overlapped, the position of the second element is a hypothesis that penetrates the first element and is perpendicular to the through surface of the first element. The line contact can be interpreted as the same position as the position of the first element. However, due to actual errors, the same location may be included in the distance imaginary line and the second element The point of contact is centered to an area of 5 mm, 3 mm, 1 mm or 0.5 mm.

The first element and the second element can be stacked in a desired configuration by observing the same position of the first and second elements by a multi-vision system.

In an embodiment, in order to allow the same position of the first and second components to be viewed through the multi-vision system, a total reflection lens may be provided such that one of the signals passes through the same position as the other signal is totally reflected or refracted. .

In addition, the total reflection lens can also be arranged to allow the optical signal passing through the total reflection lens to be in the same direction as the optical signal that is totally reflected or refracted on the total reflection lens.

Therefore, the same position of the first and second elements can be observed by setting the total reflection lens such that the position at which one of the signals passes is the same as the position and the direction of the total reflection or refraction of the other signal.

In an embodiment, the first vision camera, the second vision camera, and the total reflection lens may be provided to the first support portion or the second support portion.

In an embodiment, the connecting device may further include a connecting roller for applying pressure to the first member and the second member laminate stacked on each other by the conveying portion.

In an embodiment, the first and second components may be connected by means of use in the art to which the invention pertains. For example, the first and second components can be joined by an adhesive or a pressure sensitive adhesive. Thus, in one embodiment, the attachment roller can apply pressure to the laminate of the first member and the second member in a state where the adhesive or pressure sensitive adhesive is disposed between the first and second members.

In an embodiment, the first component may be a liquid crystal panel. Further, the second member in an embodiment may be an optical film. However, all films that can be used to connect to the liquid crystal panel can be used as an optical film without limitation. For example, the optical film may be a polarizing plate for displaying a 3D image, a retardation film, or an optical filter.

In an embodiment, the first component may be a liquid crystal panel formed with a UR region and a UL region thereon, and the second component may be an optical filter for displaying a 3D image and having an FR region and an FL region formed thereon. . Therefore, the connection device may be a manufacturing device of the 3D image display device or a part of the manufacturing device of the 3D image display device.

In an embodiment, in order to make the suction force at the center of the first or second support portion smaller than the suction force at the edge, the hole is applied through a hole at the edge of the support piece. The applied suction force can be adjusted so that the suction force at the edge of the above-mentioned support sheet is larger than the center of the support sheet. The edge and center of the support sheet can be understood by referring to FIG.

In an embodiment, the first element may have a pattern having different characteristics formed thereon, the pattern includes a first area and a second area, and the second element may have a pattern having different characteristics formed thereon, the pattern including the Three regions and a fourth region. Furthermore, the stacking of the first and second elements may be performed in such a manner that the first region overlaps the third region and the second region overlaps the fourth region in the laminate.

In an embodiment, the first component may be a liquid crystal panel for displaying a 3D image, including a UR region as a first region and a UL region as a second region. Further, the second component may be an optical filter for displaying a 3D image including an FR region as a third region and an FL region as a fourth region. Therefore, the stack of the liquid crystal panel for displaying the 3D image and the optical filter for displaying the 3D image can be performed in such a manner that the UR region overlaps the FR region and the UL region overlaps the FL region in the laminate.

In one embodiment, the method of fabricating the laminate may further utilize a multiple vision system that identifies the locations of the first and second components in a state in which the first component and the second component form a closed space.

As noted above, for example, a multiple vision system can include a first vision camera, a second vision camera, and a total reflection lens. In other words, the total reflection lens can cause the optical signal emitted from the first or second vision camera to pass through the total reflection lens and then to the first or second element. The operation of the multiple vision system can be as described above.

In an embodiment, the method of manufacturing the laminate may further include applying pressure to the laminate of the first and second members through the connecting roller. Further, in the laminate of the first and second members, a usual adhesive or pressure-sensitive adhesive can be used between the laminates of the first and second members, as shown in the above figure. Therefore, the first or second element laminated body provided by the adhesive or the pressure-sensitive adhesive can be connected by applying pressure through the connecting roller.

In one embodiment, the method of manufacturing the laminate may be part of a method of manufacturing a 3D image display device or a method of manufacturing a 3D image display device.

The details of the exemplary embodiments of the present invention are described in detail below with reference to the accompanying drawings.

In the following, referring to Figures 3 to 5, a preferred embodiment of the present invention will be shown. However, the scope of the invention is not limited to the following embodiments.

3 is a side view of the connecting device according to an embodiment, FIG. 4 is a plan view of the connecting device shown in FIG. 3, and FIG. 5 is a bottom view of the connecting device shown in FIG. When the connecting device is viewed from above, the first member 100 will be hidden by the first support portion 11, so that the first member 100 is shown by a broken line in FIG. Further, when the connecting device is viewed from below, the second member 200 cannot be observed, and therefore, the second member 200 is shown by a broken line in FIG. In FIGS. 3 to 5, the same reference numerals denote the same elements.

In an embodiment, as shown in FIG. 3, the connecting device may include a first support portion 11, a second support portion 12, and a transfer portion (not shown). Fig. 3 shows the state of the connecting device at one point, and shows that the first support portion 11 and the second support portion 12 are disposed to face each other and are vertically arranged. However, the first support portion 11 and the second support portion The configuration of 12 can be freely modified through the transmission unit. As shown in FIG. 3, the connecting device has a multi-vision system 13 mounted therein and provides a connecting roller 14. As shown in FIG. 3, in an embodiment, the multiple vision system 13 and the attachment roller 14 can be mounted in the second support portion 12. In particular, the multiple vision system 13 can be mounted to the first support or the second support to identify the position of the first and second components in the enclosed configuration. In this case, after confirming the mounting positions of the first member and the second member, the mounting process can be performed immediately to improve the connection accuracy. However, FIG. 3 depicts only one embodiment, and the position at which the multiple visual systems are provided by the connecting device, as well as the position at which the roller is mounted, can be easily changed by those skilled in the art.

Referring to Figure 6, an embodiment is shown illustrating a first support portion of the attachment device. The support portion 11 may include a support piece 111 on which the first member 100 may be held. For example, the support sheet may have at least one hole 113 formed therein. In the figure, the hole 113 of the support piece 111 is exaggeratedly shown, and the actual hole 113 can be very small. For example, a mesh plate can be utilized as a support sheet.

Further, the first support portion 11 may include a fixing device 112 through which the first member 100 may be fixed by a suction process. In Fig. 6, the direction in which the fixing device 112 draws in gas through the hole 113 of the support piece 111 is indicated by an arrow. The first support portion 11 shown in FIG. 6 includes a support piece 111 and a fixing device 112. The light element 134 is disposed on a region of the support piece 111 where no hole is formed to construct a first support portion having the same structure as the first support portion 11 shown in FIG.

The second support can secure the second component in a variety of ways. Like the first support portion, for example, the second support portion includes a support sheet and a fixing device such that the second member can be fixed to the second support portion.

Although the transmission portion is not shown in FIGS. 3 to 5, the transmission portion may be used to change the relative positions of the first support portion and the second support portion, and the structure of the transmission portion commonly used in the technical field of the present invention may be used. But it is not limited to this.

The multiple vision system allows the connecting device to connect the first and second components with a high degree of precision.

In an embodiment, the highly precise connection of the first and second elements may mean that the pattern formed thereon includes the first element 100 having different characteristics and the second element and the pattern formed thereon includes The third member 200 of different characteristics and the second member 200 of the fourth region are joined to form the laminate 300, and overlap and the second sum between the first and third regions of the first and second component laminates There is almost no error in the overlap between the fourth regions. The above-mentioned errors include manufacturing errors generated in practice, and may include, for example, tolerances of 100 μm or less, 50 μm or less, 30 μm or less, or 10 μm or less.

In an embodiment as shown in FIG. 7, a multiple vision system can be disposed under the first component 100 and the second component 200. As described above, the multi-vision system 13 can include a first vision camera 131, a second vision camera 132, and a total reflection lens 133. For example, as described above, according to the incident angle of light entering the total reflection lens, the total reflection lens can transmit light without refraction or can be refracted to transmit light first, or can totally reflect light.

In an embodiment shown in FIG. 7, the total reflection lens 133 can be used to refract the optical signal of the first vision camera 131 by the total reflection lens 133, and One of the first and second components is reached, and the second vision camera 132 can pass through the total reflection lens and reach the other of the first and second components. Further, as shown in Fig. 7, the total reflection lens is also used to refract and penetrate the optical signal at the same position on the total reflection lens in the same direction, so that the same positions of the first and second elements can be observed. The above "same position" can be understood as shown in the figure.

If the structure of the first and second component configurations is recognized by the multiple vision system to be similar to the structure for identifying the first and second component laminate configurations, the first component and the second component can be connected with high precision. This is why if the arrangement of the first and second elements is identifiable in a state in which the first and second elements are placed close to each other, the first and second elements can be minimized while the first and second elements remain in the configuration. The reason for the action connection. If the structure identifiable by the first and second component configurations is that the first component is spaced apart from the second component by a particular distance, although the configuration of the first and second components is precisely adjusted, when the relative positions of the first and second components are Upon change, the first or second component is offset from the initial configuration to connect the first and second components. Therefore, the connection accuracy of the first and second components may be lowered.

The multi-vision system 13 is configured as in the embodiment shown in Fig. 7, and the position can be recognized on the running link device in a state where the first member 100 and the second member 200 are disposed in a substantially closed configuration. For example, at this time, the distance between the first member and the second member to form a closed structure may be 10 mm or less, 9 mm or less, 8 mm or less, 7 mm or less, 6 mm or more. Small, 5 mm or smaller, 4 mm or smaller, 3 mm or smaller, 2 m Meters or less, or 1 mm or less. Thus, by utilizing multiple vision systems, the degree of sophistication of the first and second components can be increased.

In an embodiment, the multiple vision system can further include an optical component. For example, light element 134 can function in a process that utilizes a visual camera to identify the position of the component. Additionally, for example, as shown in FIG. 3, light element 134 can be configured to face the first and second vision cameras.

In an embodiment, the attachment roller 14 can be used to apply pressure to the laminate of the first component 100 and the second component 200. At this time, in a state where the relative positions of the first member and the second member are changed by the transport portion, the first member and the second member may allow the first member and the second member to be stacked on each other.

For example, as shown in FIGS. 3 and 5, the connecting roller 14 may be disposed in the second support portion 12. In an embodiment, the connecting roller 14 can be spaced a distance from the support piece when the connecting device is not in operation. Further, although the connecting device is in operation, the connecting roller 14 may be spaced apart from the pressure sensitive adhesive pad except when the first member and the second member are connected. However, when pressure is applied to the first and second members, the connecting roller 14 is moved and brought into contact with the rear surface of the pressure-sensitive adhesive pad to be applied in a state where the connecting roller is in contact with the rear surface of the pressure-sensitive adhesive pad. Pressure to the first and second components.

The connecting means is a means for connecting the first element and the second element to each other, for example, the connected first element and the second element may be elements of an optical device requiring precise connection. In an embodiment, one of the first component and 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 displaying a 3D image.

In an embodiment, the connecting device can be a device for manufacturing a 3D image display device or for manufacturing a partial 3D image display device.

Referring to Fig. 8, there is shown a method of manufacturing the first and second element laminates using the above-described connecting device.

Referring to Figure 8, an embodiment is shown in which the first component 100 can be placed on the first support portion 11. In an embodiment, the first component 100 can be fixed to the first support portion 11 by a hole through a suction process. Further, the second member 200 may be fixed to the second support portion 12. The process of securing the second component 200 to the second support portion 12 can be the same as securing the first component to the first support portion. The relative position at which the first member 100 is fixed to the first support portion 11 and the second member 200 is fixed to the second support portion 12 is moved by a transport portion (not shown), thereby causing the first member 100 and the second member 200 They may be stacked on each other to provide a laminate.

At this time, in order to make the laminate highly accurately connected, the configuration of the first and second members can be adjusted by means of a multi-vision system. Further, in order to connect the first and second members well, a pressure can be applied to the laminate of the first and second members by the connecting rollers.

In an embodiment, the first component may be an element having a different characteristic pattern formed thereon, the pattern comprising the first region and the second region, and the second component may be an element having a different characteristic pattern formed thereon. The pattern includes a third region and a fourth region. As shown above, for example, the first element may be a liquid crystal panel having a pattern formed thereon, the pattern including a UR area and a UL area, and the second element may be an optical filter for displaying a 3D image, the pattern including the FR area and FL area. In other words, the first area and the second area of the liquid crystal panel may be the UR area UL area, respectively, and are used to display 3D. The third and fourth regions of the optical filter of the image may be the FR region and the FL region, respectively. Therefore, in a state in which the liquid crystal panel for displaying the 3D image and the optical filter are stacked on each other, the multi-vision system can recognize whether the UR region matches the FR region, and whether the UL region matches the FL region. The above matching means that the UR does not overlap with the FL area, but overlaps exactly with the FR area. However, the matching described above may include manufacturing tolerances that are actually produced. The manufacturing error is in the range of 100 μm or less, 50 μm or less, 30 μm or less, or 10 μm or less, as described above.

If the above match is wrong, the relative position of the first element and the second element can be adjusted to obtain an exact match. Through the above process, the first and second components can be highly accurately connected. In an embodiment, in the case where the laminate is a 3D image display device, the UR region of the liquid crystal panel for displaying the 3D image and the FR region of the optical filter can be accurately matched to each other, and the UL region and the FL region can be Match each other exactly. Therefore, the 3D image display device manufactured by the above manufacturing method has little chance of generating crosstalk interference to produce high quality 3D images.

In one embodiment, the identification of the phase of the first and second components is obtained through a multi-vision system, as described above, in a closed configuration. Therefore, in a state where the first and second elements are configured to match the two elements, the first and second elements can be stacked with only minimal action.

The first and second elements configured by the multiple vision system can be stacked on each other in a state in which the two-element configuration is maintained. If the closed structure of the multiple vision system operates in a state where the first and second components are in contact with each other, the adjustment is originally made The relative positions of the first and second members for stacking the first and second members may be omitted.

The first and second component laminates can be formed by providing a conventional adhesive or pressure sensitive adhesive between the first component and the second component. At this time, the first and second members are connected by applying pressure to the first and second member laminates through the connecting roller.

The first and second component laminates produced through the above process are unloaded and shipped as a product, or delivered to a subsequent process.

The exemplary connecting device of the present invention can connect various components with high precision. For example, the connection device can connect a liquid crystal panel and an optical filter for displaying 3D images with high precision to provide a 3D image that produces minimal crosstalk interference.
