Generally, tempered glass is widely used as a screen of a display device. In order to manufacture a tempered glass having excellent hardness and strength, a tempering process of glass is required.

Generally, glass strengthening is classified into physical strengthening and chemical strengthening. In general, physical strengthening is performed by heating the glass at a temperature of 550 to 700 ° C. by using glass having a thickness of 5 mm or more, Which is mainly used for tempered glass doors, automobile glasses, and the like.

On the other hand, the chemical strengthening is to strengthen the glass by substituting the potassium ion of the sodium ion and the potassium nitrate solution in the glass by immersing the thin plate glass in the reinforcing furnace containing the potassium nitrate solution at 450 ° C for 3 hours or more, It is used to strengthen thin glass of 2.0mm or less.

Recently, a manufacturing apparatus capable of manufacturing tempered glass through a method of accelerating the ion exchange reaction rate of sodium ions and potassium ions in the glass surface layer by ion exchange of a small amount of molten salt in the melt containing the molten potassium salt Has been proposed.

1 is a perspective view of a tempered glass manufacturing apparatus for chemically tempering glass using such a potassium nitrate solution.

The jig transmission unit 2 and the unloading robot 3 are mounted on the guide rail 11, The hot water tank 7 and the heat water tank 8 are transferred to the preheating tank 4, the tempering tank 5, the seawater cooling tank 6, the hot water tank 7, and the glass tank 8 by sequentially transferring the racks 12, And a control box 13 for managing the tempered glass manufacturing apparatus as a whole. The control box 13 is a reinforced glass manufacturing apparatus for carrying out the reinforcing processing and carrying out the jig 12 to which the completed tempered glass is mounted.

As described above, the tempered glass manufacturing apparatus comprises a main frame 1 as a basic frame, guide rails 11 which are parallel to both left and right sides of the main frame 1 so that the robot can move in parallel, A preheating tank 4 for heating the glass before the glass is firstly heated to prevent thermal deformation and cracking during the heating, and potassium nitrate (KNO3) is heated and melted to maintain the potassium nitrate in a molten state (6) for gradually cooling the temperature of the tempered glass in the tempering tank (5), a hot water tank (6) for washing the tempered glass cooled in the hot and cold bath (6) (7) and a heat water tank (8).

In the tempered glass manufacturing apparatus shown in FIG. 1, six baths are spaced apart from one another in the longitudinal direction, and each of the baths has an internal heating unit having a heater built therein. Each of the sets has a door rail A door that is opened and closed by a folding door is provided to prevent the temperature from being maintained or the inclusion of impurities.

In the reinforcement treatment of the disk glass, the jig transferred along the guide rails provided on the top of the e-mail frame is moved horizontally by the motor power to the jig on which the disk glass is mounted, so that the disk glass preheated in the preheater (4) ).

After the glass plate strengthening process is performed, the temperature is raised from 380 ° C. to 500 ° C. in preheating, and the temperature is maintained for 30 minutes to 120 minutes. To the potassium nitrate solution (KNO 3) heated to 450 ° C. in the tempering bath The glass plate was moved to the cold bath (6) for 4 ~ 6 hours so that the strengthening was performed. The tempered glass plate was gradually cooled to 100 ° C to remove the stress, and the first and second washing were performed in the hot water bath and the heat bath .

The sheet glass to be reinforced to be conveyed in the reinforcement treatment process of the disk glass is loaded on the jig and moved according to the process order by the jigger.

At this time, the plate glass is moved in parallel with the guide rail along the guide rails while being loaded on the stacking jig. In this case, the conveyance carriage is provided with a conveyance casing for accommodating the jig on which the plate glass is loaded. The conveyance casing may be selectively provided with a conveyance casing having no heater for heating the plate glass and a conveyance casing with a heater.
