Description

[0001] Curved glass surface polishing device [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved glass surface polishing apparatus, and more particularly, to a curved glass surface polishing apparatus capable of improving the productivity of a curved glass by effectively polishing the surface of a curved glass having various curvatures at a time in a short time.

Glass (琉璃) is an object of high transparency which is obtained by melting silica, sodium carbonate, calcium carbonate, etc. and then cooling it. In the past, silicate glass mainly composed of silicic acid has been a typical example. Currently, however, an oxide such as borate glass, phosphate glass Glass is representative.

Such a glass is used for a wide variety of purposes, such as a glass plate, a bottle glass, a mirror glass, a glass tableware, etc., and is also used for imitation jewelry, base glass for photo filter, optical glass and glass for glasses. It is used as a material for high-grade tableware and the like.

On the other hand, the use of reinforced glass reinforced by heating the molded plate glass at 500 to 600 ° C, which is close to the softening temperature, compressively deforming the glass surface portion by using the compressed cooling air or chemical method, .

Tempered glass has 3 to 5 times higher bending strength than normal glass, 3 to 8 times higher impact resistance, and superior heat resistance. However, since the glass itself maintains the balance of force in the inside, even if one side is cut a little, the whole is destroyed by the pieces of red bean size. Therefore, it is necessary to make the shape suitable for the purpose before reinforcing treatment. Recently, it is widely used as display glass for mobile devices and the like.

Recently, IT (Information Technology) industry has greatly developed, and the development and consumption of high-end products such as tablet PC, smart phone, smart pad and smart watch have increased greatly. In recent years, as the IT technology has been greatly developed, when the user touches the display while looking at the display, the position of the acrylic resin is inputted to the computer and the command is executed. It has become common to use a tempered glass on the surface of a display in order to prevent the touch panel display from being damaged due to frequent touches of the screen and enhance the durability due to generalization of a touch panel display which is a type of interactive graphic input device to be.

The manufacturing process of the tempered glass used for the touch panel display is briefly described as follows: (1) cutting the hardened glass plate into a window glass shape of the product size, (2) machining holes as many as necessary for the cut glass window, (3) chamfering the edge of the window glass and the edge of the hole, (4) polishing the both sides of the window glass, and (5) washing and drying the finished window glass. In the case of cutting with window glass, there is a disadvantage that the side reinforcement does not work and it breaks well. In recent years, disc glass has been cut first in accordance with the finished product size, and then the product is manufactured by a post process.

On the other hand, as described above, the reason for polishing the both surfaces of the window glass in the process of manufacturing the tempered glass used for the touch panel display is that the precision of the surface of the window glass formed by cutting the reinforced glass plate is lowered This is because when the window glass having such a low surface precision is used for the touch panel display, a malfunction occurs in the touch operation or the precision of the operation deteriorates.

Therefore, in the case of tempered glass used for the touch panel display, since it is necessary to polish the surface precisely in order to increase the surface precision, CNC (Computer Numerically Controlled Machine Tool) The surface is generally polished by a polishing process.

Patent Registration No. 10-0584053 Japanese Patent Application Laid-Open No. 10-2006-0016941

As described above, in order to polish the both surfaces of the tempered glass, which is mainly used in the touch panel display, CNC has been used in the related art. However, since CNC costs tens of millions of won per unit, In addition, in the case of a CNC, since a window glass cut to a finished product size is fixed to a jig and then the surface is polished, a large amount of window glass can not be polished at a time. Therefore, in order to polish a large amount of window glass, There is a problem in that a large burden is imposed on the purchase of the equipment.

In recent years, the use of curved glass having a non-flat curved surface has been increasingly used in tempered glass used for displays. In the case of curved glass, a curved surface has a curved surface, and a polishing pad is attached to a CNC head having one axis, To polish the surface of the glass, rotate the jig holding the curved glass, or rotate the CNC shaft with the B axis unit (tilting unit) to polish the curved glass in the four axis (X, Y, Z, However, this requires a lot of movement of the head or jig, which causes a problem that the polishing rate is delayed and the productivity is significantly lowered.

Recently, the production of curved glass having not only a single curvature but also various curvatures at the same time has been increasing. In the case of such a curved glass, when the curved surfaces of different curvatures are polished, The polishing pad is attached to the CNC head having a single shaft so that polishing of a curved glass having different curvature curves at the same time requires more working time, In addition to lower productivity than polishing the surface, in order to polish different curves using a CNC with a single head, the curved surfaces having different curvatures are sequentially polished. In this process, curved surfaces having different curvatures There is a sense of unity in the part to meet. In the case of such defects, manual correction is required to increase the labor cost due to manual work. In the process of manual correction, the curved glass It is inevitable to develop a curved surface polishing apparatus capable of high-quality polishing while achieving high productivity while frequently suffering damage or breakage.

The present invention relates to a curved surface grinding apparatus for polishing a surface of a curved glass surface, which comprises a main body 1 having a guide bar 101 and a support 102 on an upper portion thereof; A jig part (2) provided with a jig means (206) for fixing a curved glass and movable along the guide bar (101); And polishing means (3a, 3b, 3c, 3d) provided on the supporting table (102) for simultaneously polishing a flat surface and a curved surface of the curved glass fixed to the jig means (206) Thereby achieving the object of improving the productivity of the curved glass by effectively polishing the surface of the curved glass having a flat surface and a curved surface at the same time in a short time while having a simple structure.

As described above, the curved surface polishing apparatus of the present invention has a simple structure and is easy to manufacture, and the manufacturing cost is low, thereby reducing the installation cost of a device for polishing a curved glass.

In addition, since the surface of the curved glass having curved surfaces of various curvatures at the same time can be efficiently polished in a short time, the time required for polishing the curved glass can be greatly shortened, and a large amount of curved glass can be polished simultaneously, The productivity of the glass is greatly improved, so that the manufacturing cost of the curved glass can be reduced.
