In a conventional liquid crystal removing nozzle for a convex surface glass panel, the strength of the wind pressure of the air blown out from a plurality of blow holes provided in the nozzle depends on the root of the nozzle. It was difficult to uniformly blow off the liquid crystal adhering to the convex surface glass panel because the middle part and the tip part were gradually different. Therefore, there is a drawback that unevenness of liquid crystal is blown out on the convex surface glass panel.

Therefore, the present invention improves the drawbacks of the liquid crystal removing nozzle of the conventional convex type surface glass panel, and blows out from the blowing hole at any portion from the root portion of the nozzle to the tip portion through the intermediate portion. The strength of the wind pressure of the gas is made uniform so that unevenness of the liquid crystal is not blown out on the convex surface glass panel.

[0011]

The present invention adopts the following means in order to solve the above problems.

(1) A plurality of convex surface glass panels are aligned and housed in a cassette, a nozzle is arranged on a side of a box surrounding the cassette, and a plurality of blowing holes are provided in the nozzle in a line and the spiral Liquid crystal removal nozzle for a convex-faced glass panel in which a wire-shaped wire is inserted and a plurality of blow-out holes provided in the nozzle face a plurality of convex-faced glass panels.

(2) The liquid crystal removing nozzle for a convex surface glass panel according to the above (1), wherein a pair of nozzles are arranged on both sides of the convex surface glass panel so as to face each other.

(3) The liquid crystal removing nozzle for a convex surface glass panel according to the above (1), wherein a duct for forced exhaust is 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 in the upper half part, a quadrangular pyramid-shaped surface in the lower half part, and a duct 8 at the lowermost part.

Nozzles 5a are provided on both inner side surfaces of the upper half of the box 4.
Place 5b. Helical wires 6a and 6b are inserted into the inner diameters of the nozzles 5a and 5b, respectively.
A plurality of blowing holes 7a and 7b are provided in a line. The plurality of blowing holes 7a and 7b are opposed to both sides of the convex surface glass panel 1, respectively.

Since the helical wires 6a and 6b are inserted into the inner diameters of the nozzles 5a and 5b, respectively,
Air turbulence and Karman vortices are generated in the nozzles 5a, 5b, and the wind pressure of the air blown out from the blowout holes 7a, 7b at any portion from the roots of the nozzles 5a, 5b to the tip of the nozzles 5a, 5b. It is also uniform.

By blowing air having a high wind pressure evenly through the blowing holes 7a, 7b at the roots, middle portions and tip portions of the nozzles 5a, 5b, and by blowing the liquid crystal attached to the convex surface glass panel 1 for a required time. , Blow off the adhered liquid crystal.

The blown-off liquid crystal is discharged to the outside from the duct 8 at the bottom of the box 4 and collected.

[0021]

As is clear from the above description, according to the present invention, a plurality of wires extending from the root portion of the nozzle to the tip portion of the nozzle through the intermediate portion are provided by the action of the spiral wire inserted in the inner diameter portion of the nozzle. Since it is possible to blow out a gas having a uniform wind pressure from the blow-out hole, it is possible to surely blow off the liquid crystal adhered to the plurality of convex surface glass panels evenly.
