The present invention relates to a method for manufacturing tempered glass for display, and more particularly, to a method for manufacturing tempered glass for display, which improves productivity by preventing a defect due to individual processing by processing a plurality of processes simultaneously and reducing labor costs.

In general, PCs used for display for mobile phones, medical devices, touch screens, navigation, etc. are made of PC materials, but recently, they are being replaced by tempered glass.

In manufacturing, general glass (non-reinforced) is cut to the size of the window of the applied product, cut in the water jet method, etc., and then ground to the side. Thereafter, heat treatment is performed while chemicals are added to the surface of the glass. At this time, fine cracks are generated in the process of cutting the glass before the tempering process. If the tempered glass process is performed in this state, the defect rate is significantly increased. That is, defects such as breakage of the tempered glass, diffuse reflection, and blurring of letters occur due to the microcracks generated during cutting and cutting.

Therefore, the method of individually reinforcing the cut glass has a limit in reducing the defect rate and increases the manufacturing cost.

It is said that all processes are performed in a single furnace to improve the quality by preventing external impurities from adsorbing and maintain high productivity with a simple process.However, since the single plate glass is processed by a single jig, The problem remains.

An object of the present invention for improving the conventional problems as described above, to provide a method for manufacturing a tempered glass for display to improve the productivity by preventing a defect due to individual processing by processing a plurality of simultaneously and to reduce the labor.

In order to achieve the above object, the present invention provides a method for producing tempered glass for display: a first step of producing a general glass plate as a tempered glass plate; A second step of attaching a protective film divided into a plurality of areas on an upper surface and a bottom surface of the tempered glass sheet of the first step; A third step of applying the acid-resistant solution to the upper and lower surfaces by injecting the tempered glass plate of the second step onto a printing machine; A fourth step of generating a plurality of tempered glass cells by injecting the tempered glass plate of the third step into an etching machine on a jig; And a post-treatment step of washing the tempered glass cell of the fourth step.

In addition, according to the present invention, the second step is attached to the protective film, cut to distinguish the square and the edge portion, characterized in that for removing the square portion.

In addition, according to the present invention, the third step is characterized by using a steel sheet to be pressed to the protective film having a through-hole for inserting the fixing pins on both sides while being cut into a plurality of areas therein made of thin steel.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a method for manufacturing tempered glass for mounting on a display, the display means a window for providing visual information in various electronic devices, including mobile phones.

In the first step of the present invention, the general glass plate 12 is subjected to a process of producing the tempered glass plate 15. The general glass plate 12 is preheated, heated, and cooled in a sequential process to produce a tempered glass plate 15. Preheating, heating and cooling are carried out continuously by using the respective furnaces and transporting the common glass plate 12 to the bogie phase.

In addition, the second step of the present invention is a process of attaching the protective film 20 divided into a plurality of areas on the upper and lower surfaces of the tempered glass plate 15 of the first step. The protective film 20 is a material that can prevent corrosion of the tempered glass plate 15 by preventing the penetration of the etching solution in the process described later. The divided area in the protective film 20 is made of a rectangular portion 22 and the edge portion 25 as described later, where the rectangular portion 22 arranged in a predetermined size is actually a shape (size) attached to the display. .

At this time, the second step of the present invention is attached to the protective film 20, cut to separate the rectangular portion 22 and the edge portion 25, and proceeds to the process of removing the rectangular portion (22). In the case of attaching the protective film 20 in which the quadrangle portion 22 and the edge portion 25 are cut off, there is a possibility that the cutting lines are inconsistent in the upper and lower surfaces of the tempered glass plate 15. Therefore, a method of attaching the protective film 20 to the upper and lower surfaces of the tempered glass plate 15 and then simultaneously cutting the device with a cutter blade (not shown) is preferred. The cutting line may be formed along the protective film 20 toward the tempered glass plate 15 in the cutting process.

In addition, the third step of the present invention is a process of applying the acid-resistant solution 31 to the upper surface and the bottom by putting the tempered glass plate 15 of the second step into the printing machine 35 on the steel sheet 30. Step 3 is a process of applying the acid-resistant solution 31 that can withstand the etching solution through the printing machine 35, before producing the tempered glass plate 15 in the fourth step to be described later. The printing method through the printer 35 has an advantage that can be generated in various shapes such as round and holes. Therefore, the acid resistant solution 31 is printed and applied to the upper and lower surfaces of the tempered glass plate 15 from which the quadrangle portion 22 is removed by the second step, and is dried. At this time, the steel sheet 30 before pressing into the printing machine 35 is carried out by pressing the upper surface and the bottom surface of the tempered glass plate 15. Of course, when the drying is completed, the steel sheet 30 is separated, and the edge portion 25 of the protective film 20 applied to the tempered glass plate 15 is removed.

In this case, the third step of the present invention uses a steel plate 30 that is made of thin steel and has a through hole for inserting the fixing pins into both sides while cutting into a plurality of areas therein and compressing the protective film 20. Steel plate 30 is made of a thin steel, it consists of a pair of upper and lower plates to squeeze the tempered glass plate 15 attached with a protective film 20 up and down. The inside of the steel sheet 30 is cut into the same area as the rectangular portion 22 formed by the second step. In addition, it has a through hole for inserting a fixed pin for pressing the protective film 20 attached to the tempered glass plate 15 to the outside. Therefore, since the protective film 20 attached to the tempered glass plate 15 is pressed through the steel sheet 30, the acid resistant solution 31 can be more precisely applied from the printing machine 35.

In addition, the fourth step of the present invention is a process of generating a plurality of tempered glass cells 17 by injecting the tempered glass plate 15 of the third step into the etching machine 50 on the jig 40. Through the etching machine 50, the tempered glass cell 17 in which portions other than the portions to which the necessary acid solution 31 is applied is neatly removed in a molten state is generated, thereby preventing the conventional problems as described above. have. In order to reduce the man-hours, the etchant 50 may choose to spray the etchant through a plurality of nozzles.

At this time, the fourth step of the present invention uses a jig 40 having a plurality of support plates 44 on the upper plate 41 and the lower plate 42 to perform the vertical movement. The lower plate 42 of the jig 40 is provided with a guide 48 while maintaining a fixed position, and the upper plate 41 is engaged with the guide 48 to move up and down. A plurality of support plates 44 are mounted in the downward direction of the upper plate 41 via the support 46, and a plurality of support plates 44 are mounted in the upper direction of the lower plate 42 via the support 46. The support base 46 uses the resin material in which stainless steel was built. Such jig 40 can be raised and lowered as a whole by riding a roller provided in the etching machine 50.

At this time, the jig 40 may omit the support plate 44 and may have only the support base 46, but the acid resistant solution 31 applied by the sprayed etching solution is peeled off to prevent the defect from being infiltrated by the etching solution. It is preferable to use the rubber material or resin material of the same size as the acid-resistant solution 31 applied to the tempered glass plate 15.

In addition, according to the present invention is subjected to a post-treatment step of washing the tempered glass cell 17 of the third step. The post-treatment step performs cleaning to complete the tempered glass cell 17.

At this time, the post-treatment step removes the tempered glass cell 17 from the jig 40 and passes through a plurality of tanks to remove the applied acid-resistant solution 31. The tempered glass cell 17 produced by the etching machine 50 is separated from the jig 40, and continuously applied to a plurality of tanks storing pure water or a cleaning solution to completely remove the applied acid resistant solution 31. Of course, it is good to perform the tempered glass cell 17 before the jig 40 is removed.

In the above, the present invention has been described based on the tempered glass plate 15, but it is also applicable to the general glass plate 12 as it is.

Meanwhile, in the drawings of the present invention, the general glass plate 12, the tempered glass plate 15, the protective film 20, and the acid resistant solution 31 are thickly illustrated, but this is an exaggerated expression for clarity.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
