Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings.

Please refer to FIG. 1 and FIG. 3 , which illustrate a glass processing equipment 100 according to an embodiment of the present invention, which is used to process a glass substrate 200 into multiple glass sheets. The glass processing equipment 100 is formed with a working chamber 10 and includes a carrying device 20 accommodated in the working chamber 10, a sandblasting device 30, a shielding device 40, a temperature regulating device 50 and a lifting device 60.

An opening 11 communicating with the working chamber 10 is formed on the top of the glass processing equipment 100 .

The carrying device 20 is disposed at the bottom of the working chamber 10 for fixing the glass substrate 200 . In this embodiment, the glass substrate 200 is rectangular. It can be understood that the glass substrate 200 can also be in other shapes, such as circular or irregular.

Please refer to FIG. 2 and FIG. 3 , the sandblasting device 30 includes a fixing plate 310 and a sandblasting port 320 . The fixing plate 310 closes the opening 11 so as to seal the working chamber 10 . The sandblasting port 320 is vertically fixed on the fixing plate 310 and extends into the working chamber 10 through the fixing plate 310 . The sandblasting port 320 will spray very high-density sand grains to the surface of the glass substrate 200 at high speed under the action of compressed air, thereby cutting the glass substrate 200 . In this embodiment, the fixing plate 310 is rectangular. It can be understood that the opening 11 can also be formed on other side walls of the glass processing equipment 100, but at the same time, the position of the carrying device 20 needs to be adjusted accordingly so that the carrying device 20 is opposite to the sandblasting port 320 It only needs to be set, and the sand particles ejected from the sand blast port 320 can be sprayed on the glass substrate 200 at a high speed.

The shielding device 40 is disposed parallel to the fixing plate 310 and is located between the fixing plate 310 and the carrying device 20 . The shielding device 40 includes a fixed frame 410 and a netted shield 420 fixed in the fixed frame 410 . The area of the surface of the fixing frame 410 parallel to the bottom of the working chamber 10 is slightly smaller than the opening 11 , so that the shielding device 40 can fit closely through the opening 11 and be accommodated in the working chamber 10 Inside. The shield 420 is made of hard metal (such as iron), so that the sand particles ejected from the sandblasting port 320 cannot cut the shield 420, or the shield 420 wears very little under the effect of sandblasting. Therefore, the shape can be kept unchanged during use. The shielding cover 420 includes a plurality of circular blocking pieces 421 arranged in a matrix. A layer of semi-solid silica gel (not shown) is coated on the surface of each blocking piece 421 facing the bottom of the working chamber 10 . Since the silica gel is semi-solid, it is not easy to fall off from the blocking piece 421 . When the silica gel is heated to 80° C. to 120° C., it will soften and deform, and its viscosity will increase, so that the baffle 421 and the glass substrate 200 will be more closely attached to prevent a small amount of sand grains during the sandblasting process. Spraying onto the part of the glass substrate 200 that needs to be shielded will affect the flatness of the surface of the part of the glass. When the silica gel is cooled below -40° C., it loses its viscosity and is easily separated from the glass substrate 200 without remaining on the glass substrate 200 , making it easier to clean the processed glass sheet. It can be understood that the arrangement of the blocking pieces 421 is not limited to this embodiment, and other arrangements, such as curved or random, may also be used. The shape of the baffle is not limited to this embodiment, and can be set arbitrarily according to the shape of the glass sheet required by the user. For example, if the user needs a hexagonal glass sheet, the baffle 421 is designed as a hexagonal shape. polygon. The surface of the baffle 421 can also be coated with other types of glue, as long as the glue is more viscous with the glass at high temperature and weaker at low temperature, so that it is easy to separate from the glass.

The temperature adjustment device 50 is used to quickly adjust the temperature of the shield 420 . In this embodiment, the temperature adjusting device 50 is an air temperature cooling and heating device, which can rapidly increase or decrease the temperature of the working chamber 10 . It can be understood that the temperature adjustment device 50 can also be an electronic device that is in close contact with the shield 420 and its own temperature can be rapidly raised or lowered. Since the shield is made of metal, metal has the ability to quickly transfer heat. characteristics, so it can drive the temperature of the shield 420 to rise or fall rapidly.

The lifting device 60 includes four lifting columns 61 and four lifting motors 62 . One end of each lifting column 61 is fixed on the fixed frame 410 , and the other end is movably arranged on the fixed plate 310 . Each lifting motor 62 is used to control a corresponding lifting column 61 to expand and contract, thereby driving the shielding device 40 to rise or fall, so that the lifting device 60 can determine the shielding device according to the thickness of the glass substrate 200 40, so that the glass processing equipment 100 can process glass substrates 200 with different thicknesses. It can be understood that if it is only necessary to process glass substrates of the same thickness, the lifting device 60 can also be replaced with a plurality of fixing columns. In this embodiment, one ends of the four lifting columns 61 are arranged at four corners of the fixing plate 310 . It can be understood that the lifting column 61 can also be arranged at other positions of the fixing plate 310 . And the number of the lifting columns 61 is not limited to four, and may be other numbers.

The working process of the glass processing equipment is as follows: the glass substrate 200 is fixed on the carrying device 20; a layer of silica gel (not shown) is coated on the surface of the baffle 421 facing the bottom of the working chamber 10 shown); seal the fixing plate 310 on the opening 11 to form an airtight space in the working chamber 10; start the temperature regulating device 50 to adjust the temperature in the working chamber 10 to 80°C ~120°C; start the lifting motor 62 to lower the shield cover 420 and press it on the glass substrate 200; make the sandblasting port 320 start sandblasting, and the sand particles will continuously impact on the glass substrate 200 The exposed part (the part not covered by the blocking plate 421) is cut until all the exposed parts of the glass substrate 200 are cut off; The temperature is lowered below -40°C. At this time, the viscosity of the silica gel (not shown) is broken, and it is automatically separated from the glass substrate 200, and will not remain on the glass substrate 200, so that the processed glass Sheets are easy to clean. Start the lifting motor 62, pull up the shielding device 40, take out the processed glass sheet and clean it.

It can be understood that, in order to recycle the sand grains again, a plurality of air suction holes can also be provided at the bottom of the working chamber 10, and a suction nozzle and an air suction device can be connected at the air suction hole. The particle size of the powder is much smaller than the particle size of the sand, so two layers of filter screens are stacked in the suction nozzle, and the aperture of the upper filter screen is larger than that of the lower filter screen, so that the sand particles are collected on the upper filter screen ; Collect the glass shards on the lower strainer.

The glass processing equipment of the present invention can process the glass substrate into a desired shape without complex processes such as cutting, gluing, edging, and degumming, and the process is simple and can effectively improve production efficiency.

It can be understood that those skilled in the art can make various other corresponding changes and modifications according to the technical concept of the present invention, and all these changes and modifications should belong to the protection scope of the claims of the present invention.
