In the cleaning chamber part 200, the adhesive remaining by the protective film and the foreign substances adhered by the adhesive can be removed from the panel in which the protective film is peeled off. The cleaning chamber unit 200 may include a chamber 210 in which a cleaning liquid is provided to impregnate the panel into the cleaning liquid and an agitator 220 disposed inside the chamber 210 to agitate the cleaning liquid.

The stirrer 220 may include a rod-shaped shaft connected to the lower portion of the chamber 210 and an impeller connected to the shaft and stirring the cleaning liquid. The impeller may be provided on one of the upper part of the shaft and the other part of the upper part spaced apart from the lower part, and the impeller may more uniformly stir the cleaning liquid. In addition, by applying the cleaning liquid by the impeller, the cleaning liquid can cost the surface of the panel, thereby more easily removing the foreign matter adhering to the surface of the panel.

An inlet nozzle 250 may be provided in the chamber 210. The cleaning liquid is injected into the chamber 210 through the inlet nozzle 250 and the outlet 210 provided at the lower side of the inlet nozzle 250, The contaminated cleaning liquid can be discharged through the nozzle 240.

In the process of washing the panel with the cleaning liquid, the cleaning liquid may be added through the auxiliary inlet nozzle 260 or an additive may be added. The auxiliary inlet nozzle 260 has a cross sectional area smaller than that of the inlet nozzle 250 so that the degree of addition of the cleaning liquid can be finely controlled into the chamber 210 by controlling the auxiliary inlet nozzle 260 with the valve 262.

The dryer (300) may include a heating jacket (301) provided outside the dryer and supplying heat to the inside of the dryer.

The heating jacket 301 may transmit heat to the inside of the dryer 300 to dry the cleaning liquid remaining on the surface of the panel. In addition, an ultraviolet light source member 400 may be further included in the dryer 300. The surface of the panel that has been dried in the dryer 300 is irradiated with the ultraviolet light source member 400 using the ultraviolet light source member 400 to make the surface of the panel more rigid and prevent the foreign matter from adhering to the panel can do.

The ultraviolet light emitted from the ultraviolet light source member 400 may modify the surface of the panel. When the surface of the panel made of the polymer resin is irradiated with ultraviolet rays, the chemical bond on the surface of the polymer resin is decomposed and it is bonded with oxygen in the air to form a carbonyl group (-CO), a carboxyl group (-COOH), a hydroxyl group -OH) are generated, so that the polarity of the surface is increased, and a paint, a coloring agent, a coating agent and the like having high polarity are easily attached. In this case, it is the minimum requirement that the energy of ultraviolet rays should be higher than the binding energy of molecules. The energy of the chirpwires having wavelengths of 184.9 nm and 253.7 nm are 647 KJ / mol and 471.5 KJ / Is higher than the binding energy of the molecules of the carboxyl group (-COOH) and the hydroxyl group (-OH), so that the radical can be efficiently formed.

The angle of the ultraviolet ray may be changed while changing the angle of the ultraviolet ray to 5 to 10 degrees per second with respect to the surface of the panel. The ultraviolet rays irradiated to the panel can be made more uniform by irradiating the ultraviolet rays while changing the angle of the ultraviolet rays. When the angle of deformation of the ultraviolet ray is less than 5 degrees per second, a part where the ultraviolet ray is not transmitted to the surface is formed and the surface is not uniformly irradiated with ultraviolet rays. When the deformation rate is more than 10 degrees, And thus the surface characteristics can be non-uniformly provided.

The fixing part 403 may be screwed into a thread-like groove provided on the inner wall of the dryer 300 to be fixed. The screw connection reversibly proceeds to easily replace the ultraviolet light source member 400 when the life of the head unit 401 is completed.

The cleaning liquid may be composed of 50 to 95 parts by weight of an amide-based solvent, 5 to 15 parts by weight of an acetate-based solvent, and 15 to 30 of an alcohol-based solvent.

The amide solvent may be at least one compound selected from N, N-dimethylacetamide, N, N-dimethylformamide, dimethylsulfoxide, N-methylpyrrolidone and formamide.

The acetate solvent may be selected from the group consisting of benzyl acetate, butyl butyrate, ethyl butyrate, ethyl pentanoate, isobutyl acetate, methyl benzoate, , Amyl acetate, and 2-methoxyethyl acetate.
