BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for cutting a glass for a cover glass used in a touch panel of a smart phone or a smart pad of an IT device and a glass used for a smart phone touch panel cover glass is 0.7 mm or 0.55 mm, or 0.4 mm or less, it is difficult to work because it is easily damaged due to impact or pressure, and it is difficult to work and time is long, so productivity is low.
Conventional methods for cutting a material with a low brittleness such as glass are to continuously grooved with a hard hard tool such as a diamond glass knife or by continuously heating the glass surface with a laser, (10 ~ 20 sheets) of the sheet glass is broken with a special adhesive agent because the sheet glass of the sheet glass is easily broken. It is used to fix the glass like one glass and to cut out the outer shape using the high hardness and torque of the high-speed rotating diamond saw or the high water pressure of the water jet water, and then melt the adhesive by hot water to melt the glass.
Especially, after cutting the outer edge of the glass, the hole machining work in the middle of the glass surface of the glass product is done by using a diamond drill bit in a high-speed rotating CNC machine and finely cutting it very slowly.
As a tool for cutting glass, hard diamond glass knife, laser, water jet, etc. are used. When the glass product to be cut is in the same shape or is continuously cut according to the standard, it is difficult to process because it is weak in brittleness. The inner hole is cut into square shape and then the inner hole is separately processed by the additional process. Therefore, it takes a long time and the breakage is large, so that the yield of obtaining a good quality product is low and the productivity of the work is not good .

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art

The object of the present invention is to provide a structure in which glass is cut without cracks, the cutting speed is improved, and the outer and inner holes of the outer shape of the glass are simultaneously cut by a single process operation to lower the cracks of the glass. And a method thereof.

The present invention relates to a method of cutting a glass and a method for solving the problem of the apparatus, comprising the steps of cutting a glass product by forming a mold for cutting the outer and inner holes of the outer shape and the outer shape of the product, This is a fusion method in which a mixture of uniformly activating microparticles in pure water is sprayed on a glass and the glass is cut by ultrasonic wave oscillation driving in a die of a mold processing machine.

It is difficult to precisely cut a large quantity of a product of a certain size or shape of a glass product to be cut in a thin brittle glass. Therefore, we cut the glass into a square shape and cut, polish, and map the rounded parts of the corner to match the dimension specifications. The hole drilling is time consuming because it is necessary to work at a low machining speed in a high speed CNC machine with a diamond drill bit, Productivity is low because of the many burning of glass due to many complicated process of hole processing of polygon.

Since the glass plate can not be processed simultaneously with the cutting process of straight, round, or rounded rounds, it takes a long time to perform a single cutting operation for each process, Glass processing is not easy to produce large quantities of identical and precise products.

By forming a blade of a mold processing apparatus of a standard or pattern type of a product to be cut into a thin thin plate glass, and spraying a mixture of microparticles and pure water on the glass, the ultrasonic wave oscillation is driven to cut the mold, This is a method of cutting glass products of the same size continuously over time. This method does not apply shock or pressure to the entire glass surface, or does not apply a load, so that breakage is small. Cutting of glass The cutting part of the glass surface is finely pulverized and cut in the form of micro particles by the ultrasonic motion by the width of the thickness of the blade of the apparatus in which the microparticles are processed in a noncontact manner in which the cutting edge of the processing apparatus is not in contact with the glass surface .

According to the glass cutting apparatus and method of the present invention having the above-described structure, the blade of the cutting die processing apparatus according to the product standard of the glass to be processed is constituted, and the ultrasonic wave and the microparticles are fused to the pure mixture using the ultrasonic wave and the microparticles as the medium, Since the outer and inner holes of the rounds are simultaneously cut by a single process, the loss of glass is small and the cutting speed is increased by increasing the efficiency of the cutting work and shortening the working time. There is an effect of improving the quality.

The thin glass (440) of 1.1mm or less, 0.7mm, 0.55mm, or 0.4mm or less of the cover glass used for the touch panel surface of the smartphone or pad of the IT equipment is a weak brittle material. Cutting work is difficult because it breaks easily and breaks.

The present invention is a method for simultaneously cutting the inner holes of a glass product to be cut together with outer edges of a straight line, a curved line, and a rounded corner, A method of forming a mixture 320 in which microparticles are uniformly activated in pure water by using microparticles as a cutting medium and driving ultrasonic waves in a cutting edge of a processing machine to cut and cut the cut portions of the glass to be.

More specifically, the die 250 for cutting the glass cuts the outer periphery of a product outline such as a curve, a straight line, a circle or a polygon that is free to match with the size and the size of the glass product to be cut, And the cutting edge of the processing machine is fixed to the ultrasonic horn. The frequency of the ultrasonic wave for driving the ultrasonic horn is 23 (Ultra Sonic) which is driven by oscillation at a frequency of 1 kHz is used.

Mold processing machine fixed to ultrasonic horn for cutting glass Ultrasonic wave is continuously oscillated on the bottom surface of the blade tip, and silicon carbide and boron carbide 5 The mixture 320 is diluted and dispersed in the size of 탆 to 20 탆 and is sprayed on the glass surface and between the edges of the cutting die and the ultrasonic wave is oscillated in the blade 250 of the processing machine to drive the microparticle mixture . When the ultrasonic wave is driven at the bottom surface of the cutting edge of the cutting edge of the cutting edge of the edge of the cutting edge of the cutting edge of the cutting edge of the cutting tool, 530) is finely cut and ground in the form of microparticles.

The constitutional conditions at the time of cutting the glass include the glass surface to be cut when the microparticles of the mixture flowing on the glass surface are mixed with the pure water and only the local portion of the glass to be cut is crushed, The maximum spacing between the edge of the blade edge and the bottom surface should not exceed 10 times (200 μm) of the microparticle size, and the minimum interval must be 2.5 or more times (50 μm) The cutting operation is performed.

Since the microparticles as the cutting medium which is driven by ultrasonic wave oscillation is a method in which the respective particles are fine and the bottom surface of the edge of the die for cutting the shape or shape according to the standard of the glass product grinds the local portion on the glass surface, Do not apply the product's overall impact or pressure. Therefore, according to the specification of the product or the shape of the same shape, the outer or inner holes of the glass to be cut are simultaneously cut in the range of the bottom surface of the cutting metal mold processing machine, And cutting the glass surface 530 of the local portion as much as the area, cutting and crushing the microparticles.

More specifically, ultrasonic waves are generated by oscillating on the bottom surface of a blade of a cutting tool in a non-contact manner in which the blade of the cutting tool is not in direct contact with the glass surface, and microparticles and microparticles, which are cutting materials, When the activated mixture 320 is sprayed and flowed between the cutting edge of the cutting tool and the glass surface to be cut, and the ultrasonic oscillation is driven on the blade of the cutting machine, the microparticles of the mixed medium, The glass surface 530 of the local portion close to the bottom surface area of the glass product is cut and crushed into microparticles, and the outer and inner holes of the glass product are simultaneously cut by a single process in the shape of the die of the die.

In the construction in which the cutting edge of the cutting device is not in contact with the glass surface, the maximum interval between the cutting edge of the processing machine and the glass surface to be cut should be within 200 μm and the optimum working range is within 50 μm to 160 μm And the ultrasonic wave driven at the edge of the mold machining apparatus is cut at a frequency of 23 kHz by crushing and cutting the glass into microparticles as much as the thickness width of the mold tool blade by a mixture of cutting microparticles and pure water.

The ultrasonic wave is oscillated to drive the mixture of microparticles to the speed at which the glass is cut by the blade of the cutting die processing machine, and the blade of the processing machine is moved to the depth of the portion where the glass is cut, The glass is cut by moving the blade of the metal mold machining apparatus in the direction of the glass product to be cut in the same manner as the cutting speed while maintaining the interval between the active space in which the work can be performed and the cutting bottom surface to be machined.

The cutting speed of the cutting edge of the glass cutting tool is proportional to the cutting area and the output of the ultrasonic oscillation. When the matching of the microparticles and the mixing medium is most effective, the edge of the cutting tool cuts the glass. The glass cutting speed is in the range of 10 μm to 100 μm per second. The glass is cut in the direction of the cutting area by moving the blade of the cutting tool.

A plurality of glass cutting methods according to the present invention are characterized in that a large number of thin glass sheets are laminated in a multilayer of 2 to 10 sheets without being bonded with an adhesive like a single glass sheet, In another cutting method, multiple blades of a cutting machine are provided, and multiple blades are cut at the same time in a single cutting step.

As another cutting method, glass cutting machine tool blades are installed in a number of 2 ~ 50 or more, so that multiple cutting is done simultaneously in one cutting process.
