2. Description of the Related Art The applicant of the present invention first bonded two upper and lower glass substrates having transparent electrodes attached to their inner surfaces with an ultraviolet curable resin with a predetermined gap provided therebetween.
We have developed and applied for a patent for equipment for manufacturing liquid crystal panels that make up one or more empty liquid crystal cells. Then, as an ultraviolet irradiation device for irradiating the ultraviolet curable resin with ultraviolet rays, a reflecting mirror is provided above the linear ultraviolet lamp, and a shutter is provided below the ultraviolet lamp, and the shutter is opened. What is configured to irradiate the ultraviolet curable resin of the liquid crystal panel with ultraviolet rays, an ultraviolet lamp, and a drum-shaped drum having an opening in the body and a condenser mirror on the inner surface, and the ultraviolet lamp as the center. It employs a shutter that is normally and reversely rotated, and is configured so that ultraviolet rays travel linearly by forward and reverse rotation of the shutter.

By the way, in the liquid crystal panel manufacturing equipment provided with the ultraviolet irradiating device configured as described above, the time for irradiating the glass substrate with ultraviolet rays is required for manufacturing the liquid crystal panel. Very short compared to the time. However, since the ultraviolet lamp cannot be turned on / off in a short time because of its structure, it is always turned on, and it is necessary to have a very large output.
Moreover, the ultraviolet irradiation device is more expensive than the glass substrate pressing device. As a result, the liquid crystal panel manufacturing equipment is
There are problems such as enormous equipment costs and very high running costs. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a liquid crystal panel manufacturing facility capable of efficiently using an ultraviolet irradiation device in manufacturing a liquid crystal panel.

[0004]

In order to achieve the above object, in the liquid crystal panel manufacturing equipment of the present invention, two upper and lower glass substrates are bonded by an ultraviolet curable resin to form one or more empty liquid crystal cells. It is a facility suitable for irradiating ultraviolet rays to an ultraviolet curable resin in manufacturing a liquid crystal panel to be configured, and is provided with an opening that pressurizes the upper and lower two glass substrates and transmits the ultraviolet rays at a ceiling position. And a plurality of glass substrate pressurizing devices installed at required intervals,
A track means mounted between the upper positions of these glass substrate pressing devices, a transport means movably mounted on the track means, and a transport means mounted on the transport means and set on the glass substrate pressing device. An ultraviolet irradiator capable of irradiating the ultraviolet curable resin of the glass substrate with ultraviolet rays.

In the equipment thus constructed, one glass substrate pressing device sets two glass substrates and presses the set glass substrates while the other glass substrate pressing device presses the other glass substrate pressing device. Irradiates the glass substrate, which is set in advance and then pressed to a required state, with ultraviolet rays by an ultraviolet ray irradiating device. After the irradiation of ultraviolet rays is completed, the ultraviolet irradiation device is moved above the one glass substrate pressing device where the pressing of the glass substrate is completed to irradiate the glass substrate with ultraviolet rays, and at the other glass substrate pressing device. Is to take out the glass substrate irradiated with ultraviolet rays and then set another glass substrate.

Will be described in detail with reference to. As shown in the drawing, three publicly known glass substrate pressing devices 1 are arranged side by side in the left-right direction at required intervals, and above the three glass substrate pressing devices 1. A rail 2 as a track means is provided so as to extend between columns (not shown).
Further, a carriage 3 as a transfer means is movably mounted on the rail 2, and an ultraviolet irradiation device 4 is mounted on the carriage 3.

The glass substrate pressing device 1 is disclosed in Japanese Patent Application Laid-Open No. 4-301814. That is, the pressure transmission plate 11 is provided so as to be able to move up and down via the electric cylinder 13 mounted on the foundation table 12, and the pressure plate 14 is mounted on the pressure transmission plate 11 via the inclination correction mechanism 15 to apply the pressure. A pressure receiving plate 16 made of a material capable of transmitting ultraviolet rays is fixedly disposed above the pressure plate 14 via a fixing plate 17, and an opening 18 for passing ultraviolet rays is formed in the fixing plate 17. The correction mechanism 15 is electrically connected to a microcomputer (not shown), and the pressure plate 1
4 and the pressure receiving plate 16 can be corrected in parallelism.

Further, the ultraviolet irradiation device 4 is provided with a supporting member 19 mounted on the carriage 3, a linear ultraviolet lamp 20 mounted on the supporting member 19, and a supporting member 19 positioned above the ultraviolet lamp 20. Reflective mirror 21 mounted on

9 and a shutter 22 attached to it.

In the equipment thus constructed, the shutter 22 of the ultraviolet irradiator 4 is applied to the glass substrate pressing device 1 on the left side, which has been set in advance and then pressed to a desired state. While being opened and irradiated with the ultraviolet rays of the ultraviolet lamp 8 through the opening 18 of the glass substrate pressing device 1, in the glass substrate pressing device 1 at the center, two glass substrates are set and The set glass substrate is pressed into a desired state. After the irradiation of the ultraviolet rays is completed, the ultraviolet irradiation device 1 is moved by the carriage 3 to a position above the central glass substrate pressing device 1 where the pressing of the glass substrate is completed, and the glass substrate is irradiated with the ultraviolet rays.
Further, similarly, the glass substrate to which the ultraviolet rays are previously projected is taken out from the glass substrate pressing device 1 on the right side.

As is apparent from the above description, according to the present invention, the upper and lower two glass substrates are pressed and a plurality of the glass substrates are provided at the ceiling position with the openings through which the ultraviolet rays can pass. Between the upper positions of the glass substrate pressurizing device of the table,
Since the transfer means is movably arranged via the track means and the ultraviolet irradiation device is attached to the transfer means, when the liquid crystal panel is manufactured, the ultraviolet irradiation device is provided between a plurality of glass substrate pressing devices. Since it can be moved appropriately and used efficiently, it has an excellent effect that the equipment cost and running cost can be significantly reduced as compared with the conventional equipment of this type.
