[0010]

In a conventional liquid crystal removing device for a convex surface glass panel, air is horizontally and symmetrically distributed from the nozzles 5a and 5b arranged on both sides of the inside of the box surrounding the cassette. Since it is blown out, the wind blown from the pair of left and right nozzles collides near the center of the convex surface glass panel as shown in FIG. 2 and becomes a blow-up state, and a liquid crystal residue 9 is generated near the center. was there.

Therefore, the present invention solves the drawbacks of the conventional liquid crystal removing device for a convex surface glass panel and arranges a plurality of convex surface glass panels arranged side by side on both sides of a box enclosing a cassette. Even if gas is blown out from the arranged nozzle,
This is intended to prevent liquid crystal from remaining near the center of the convex surface glass panel.

[0012]

The present invention employs the following means to solve the above-mentioned problems.

(1) A plurality of convex surface glass panels are aligned and housed in a cassette, nozzles are arranged on both sides of a box surrounding the cassette, and the angle at which gas is blown out of each nozzle can be adjusted and both can be adjusted. A liquid crystal removing device for a convex surface glass panel in which a plurality of convex holes are provided in each nozzle so as to face a plurality of convex surface glass panels.

(2) The liquid crystal removing apparatus for a convex surface glass panel according to the above (1), wherein the time for blowing out the gas from each nozzle is shifted by timer control.

(3) The liquid crystal removing apparatus for a convex surface glass panel according to the above (1), in which forced exhaust is performed from a duct provided at the bottom of the box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIG.

In FIG. 1, both surfaces of the convex surface glass panel 1 after liquid crystal injection are sandwiched by spacers 2, and a plurality of convex surface glass panels 1 and spacers 2 are aligned and housed in a cassette 3. Box 3 surrounds cassette 3. The box 4 has a rectangular frame for the most part, a quadrangular pyramid-shaped surface at the bottom, and a duct 7 at the bottom. The above structure is similar to the conventional technique.

Nozzles 5a and 5b are installed on both outer side surfaces of the box 4. The nozzles 5a and 5b can both adjust the angle at which air is blown out, and the position of the nozzle 5a is slightly lower than the position of the nozzle 5b. Nozzles 5a and 5b have
A plurality of blow-out holes are provided in a row, and the plurality of blow-out holes face each side of the convex surface glass panel 1.

Forced exhaustion was started from a duct 7 provided at the bottom of a box 4 surrounding a cassette 3 in which a plurality of convex surface glass panels 1 were aligned and accommodated, and was installed on one side of the box 4. Air having a high wind pressure is blown horizontally from the nozzle 5a onto the convex surface glass panel 1 for a required time by timer control. Next, air having a high wind pressure is blown from the nozzle 5b provided on the other end surface of the box 4 to the convex surface glass panel 1 slightly obliquely downward from the horizontal direction for a required time by timer control. When the nozzles 5a and 5b are used in this way, as shown in FIG.
As in the conventional technique described with reference to, the residual liquid crystal 9 does not occur near the center of the convex surface glass panel,
The liquid crystal attached to the convex surface glass panel 1 can be blown off.

Further, from the duct 7 provided at the lowermost part of the box 4 surrounding the cassette 3, forced exhaust is performed in order to prevent generation of turbulent air flow blown from the nozzles 5a and 5b and to improve ventilation. The liquid crystal that has been blown off is also collected from the duct 7.

[0021]

As is apparent from the above description, according to the present invention, it is possible to adjust the angle at which the gas of at least one nozzle is blown out, and to dispose a height difference in the arrangement of both nozzles so that each nozzle is in a line. Since the plurality of blowing holes provided in the are opposed to the plurality of convex surface glass panels, it is possible to reliably wipe off the liquid crystal residue near the center of the convex surface glass panel and the center with a gas with a high wind pressure, so be sure The liquid crystal can be removed. Moreover, the blown-off liquid crystal can be collected from the duct.
