[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a polarizing plate sticking device, and more particularly to a structure of a polarizing plate sticking device capable of suppressing expansion of a footprint even when a liquid crystal cell substrate is enlarged.
[0002]
[Prior art]
First, FIG. 2 schematically shows a cross-sectional structure of a color liquid crystal display. This color liquid crystal display comprises a liquid crystal cell substrate 1 composed of a glass substrate having a liquid crystal, an alignment film, a transparent electrode, a color filter, etc. interposed therebetween, and front and back sides of the liquid crystal cell substrate 1 (CF side, TFT side). ) Are provided.

Thereafter, after the liquid crystal cell substrate 1 is inverted, the polarizing plate 3 is similarly attached to the other surface (TFT surface) of the liquid crystal cell substrate 1.
[0005]
Here, a schematic configuration of a conventional polarizing plate sticking apparatus 2000 will be described with reference to FIG. The polarizing plate sticking apparatus 2000 includes a transport line 10 for transporting the liquid crystal cell substrate 1 in a predetermined direction. This transport line includes a first polarizing plate sticking line (CF side polarizing plate sticking line) 300 and a second polarizing plate sticking line (TFT side polarizing plate sticking line) 400. Between the first polarizing plate sticking line 300 and the second polarizing plate sticking line 400, a reversing station 700 for reversing the front and back surfaces (CF surface side, TFT surface side) of the substrate is provided. An inversion station 800 is provided on the downstream side of the liquid crystal cell substrate 1 in the transport direction of the liquid crystal cell substrate 1 on the two-polarizing plate attaching line 400. Note that a cleaning transport line 100 in the cleaning step is connected to the upstream side of the transport line 10.
[0006]
The first polarizing plate attaching line 300 is provided with a cleaning roller 301, an alignment station 302, an alignment CCD camera 303, and a polarizing plate attaching station 310 from the upstream side. Similarly, a cleaning roller 401, an alignment station 402, a CCD camera 403, and a polarizing plate sticking station 410 are provided on the second polarizing plate sticking line 400 from the upstream side.
[0007]
In the transport line 10, a first polarizing plate supply line 500 is provided so as to be orthogonal to the polarizing plate sticking station 310 of the first polarizing plate sticking line 300. The first polarizing plate supply line 500 is used to take out the polarizing plate 2 from the polarizing plate cartridge port 501 for storing a plurality of polarizing plates 2 to be attached to the CF side of the liquid crystal cell substrate 1. , A polarizing plate cleaner 504, and a polarizing plate alignment station 505.
[0008]
Similarly, a second polarizing plate supply line 600 is provided on the transport line 10 so as to be orthogonal to the polarizing plate sticking station 410 of the second polarizing plate sticking line 400. Similar to the first polarizing plate supply line 400, the second polarizing plate supply line 500 includes a polarizing plate cartridge port 601 for storing a plurality of polarizing plates 3 to be attached to the TFT side of the liquid crystal cell substrate 1, A polarizing plate take-out station 603 for taking out the polarizing plate 3 from the cartridge port 601, a polarizing plate cleaner 604, and a polarizing plate alignment station 605 are provided.
[0009]
In the polarizing plate sticking apparatus 2000 having the above configuration, the polarizing plates 2 and 3 are stuck to the liquid crystal cell substrate 1 by the liquid crystal transported from the cleaning / transport line 100 along the direction in which the long side of the liquid crystal cell substrate 1 extends. The cell substrate 1 is transported with the cell substrate 1 as it is through the first polarizing plate attaching line 300, and the polarizing plate is attached to the CF side of the liquid crystal cell substrate 1 at the polarizing plate attaching station 310 based on the procedure shown in FIGS. 2 is affixed.
[0010]

[0011]
The prior art of the invention according to the present application has been described based on general technical information obtained by the applicant.However, as far as the applicant memorizes, as prior art document information before the filing of the present application, The applicant does not have the information to be disclosed, nor is he aware of the applicant's own patent applications prior to the present application.
[0012]
[Problems to be solved by the invention]
In recent years, the size of color liquid crystal displays has been increasing. In the past, the size of color liquid crystal displays was mainly 15 inches, but in the future, 30 inches and 45 inches will be mainstream. The size of the display is expected to increase rapidly.
[0013]
As described above, when the size of the color liquid crystal display is increased, the polarizing plate sticking apparatus shown in FIG. 5 necessarily has a large footprint, particularly, a length in the transport direction. However, due to the limitations of the factory site, the footprint cannot be increased indefinitely.
[0014]
Also, in the step of attaching the polarizing plates 2 and 3 to the liquid crystal cell substrate 1, the tact time becomes long. However, even if the size of the color liquid crystal display is increased, it is necessary to suppress an increase in the manufacturing cost of the color liquid crystal display, and it is necessary to increase the efficiency of the manufacturing process of the color liquid crystal display.
[0015]
Here, in the case of the polarizing plate sticking apparatus shown in FIG. 5, the polarizing plate 2 is disposed below the liquid crystal cell substrate 1, and then the release film 2a is separated from the polarizing plate 2 to remove the liquid crystal cell substrate 1. The polarizing plate 2 was adhered to one surface.
[0016]
On the other hand, as a method for improving the efficiency of the step of attaching the polarizing plates 2 and 3 to the liquid crystal cell substrate 1 (suppressing the increase in the tact time), a tandem method is exemplified. In this tandem method, in order to effectively use the time for separating the release film 2a from the polarizing plate 2, the release film 2a is separated from the polarizing plate 2 in advance on the polarizing plate attaching line, and then separated from the polarizing plate 2. The step of separating the mold film 2a and the step of adhering the polarizing plate 2 to the liquid crystal cell substrate 1 are performed in parallel.
[0017]
However, in the case of this tandem method, since the pressure-sensitive adhesive layer is exposed for a long time, the probability that dust and the like adhere to the pressure-sensitive adhesive layer increases. In addition, when a trouble occurs on the liquid crystal cell substrate 1 side and the line is stopped, the polarizer 2 from which the release film 2a has already been separated is likely to have dust or the like adhered to the adhesive layer. It is disposed of because it is expensive. As described above, in the case of the tandem method, although the tact time can be reduced, the yield of the product cannot be improved, and the production cost of the color liquid crystal display generally increases. It is considered that the risk is high.
[0018]
Therefore, the present invention has been made to solve the above-mentioned problem, and a polarizing plate attaching device capable of suppressing an increase in the footprint of a polarizing plate attaching device without causing a decrease in product yield. Is to provide.
[0019]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the polarizing plate sticking apparatus according to the present invention, the liquid crystal cell substrate is conveyed in a predetermined direction on a surface of a rectangular liquid crystal cell substrate having a short side and a long side. What is claimed is: 1. A polarizing plate sticking device for sticking a polarizing plate to a cell substrate, comprising: a transfer line for transferring the liquid crystal cell substrate in a predetermined direction; and a polarizing plate provided on the transfer line, the polarizing plate being provided on a surface of the liquid crystal cell substrate. And a polarizing plate transport line for transporting a polarizing plate to be attached to the surface of the liquid crystal cell substrate to the attaching station.
[0020]
Further, the transport line transports the liquid crystal cell substrate along the direction in which the short side extends, so that the liquid crystal cell transported along the direction in which the long side extends on the upstream side of the attaching station. A turning station for turning the substrate by 90 degrees is provided. More preferably, the turning station is provided at an entrance of the transfer line.
[0021]
According to this configuration, in the polarizing plate sticking apparatus, the liquid crystal cell substrate is transported along the direction in which the short side extends. As a result, the length of the transfer line can be reduced as compared with the conventional case where the transfer is performed along the direction in which the long side extends. As a result, even in a polarizing plate sticking device that sticks a polarizing plate to a large liquid crystal cell substrate without increasing the length of the polarizing plate sticking device along the length in the transport direction, an increase in footprint is suppressed. It becomes possible.
[0022]
In addition, the time required for attaching the polarizing plate to the liquid crystal cell substrate is due to the length of the side along the transport direction of the liquid crystal cell substrate. It is also possible to improve the yield.
[0023]
Further, in the polarizing plate sticking apparatus, preferably, the polarizing plate transport line, a parallel line extending substantially parallel to the transport line, to directly supply the polarizing plate to the sticking station, for the transport line And orthogonal lines that are substantially orthogonal.
[0024]
Thus, by providing a parallel line extending substantially parallel to the transport line on the polarizer transport line, it is possible to suppress an increase in the footprint of the polarizer attaching apparatus. In particular, in the present polarizing plate sticking apparatus, since the liquid crystal cell substrate is transported along the direction in which the short side extends, the polarizing plate is transported along the direction in which the long side extends. Become. Therefore, by providing a parallel line extending substantially parallel to the transport line on the polarizer transport line as described above, it is possible to suppress an increase in the footprint of the polarizer attaching apparatus.
[0025]

[0028]
With this configuration, it is possible to reduce the length of the transport line as compared with the case of a conventional polarizing plate sticking apparatus that is transported along the direction in which the long side extends. In addition, the time required for attaching the polarizing plates 2 and 3 to the liquid crystal cell substrate 1 is determined by the length of the side along the transport direction of the liquid crystal cell substrate 1. It is also possible to improve the yield by lowering the probability of establishment.
[0029]
