Description

Technical Field

[0001] The utility model belongs to the technical field of ultra-thin glass cutting, and in particular relates to an ultra-thin glass transverse cutting device. Background Art

[0002] Ultra-thin glass is a relatively thin glass. Specifically, the thickness of ultra-thin glass can be between 0.33-1.1mm, and the thinnest can reach 0.12mm. Ultra-thin has many advantages such as flat surface, high light transmittance, high sensitivity, etc., so it is mostly used in more precise technical fields, such as ultra-thin glass is used in the field of electronic information, such as touch screen of electronic equipment, etc.

[0003] Ultra-thin glass is different from traditional glass in production and processing. Ultra-thin glass is mostly produced by float process. During the production process, ultra-thin glass needs to be cut. However, due to the extremely thin thickness of the glass, the traditional online cross-cutting machine can no longer meet the cutting requirements, especially in terms of the stability of cutting quality.

[0004] Specifically, during the cutting process, it is difficult to accurately control the cutting force of the glass, especially the glass with too small thickness. As a result, once there is a hollow position between the glass and the supporting surface, the glass is easily damaged, causing the glass to deform. In severe cases, the glass may be crushed.

[0005] Specifically, the current mainstream cutting method uses air flotation cutting. During the air flotation cutting process, gas is used to form buoyancy to keep the bottom of the glass under a relatively uniform support force. The most common method is to place the glass on an air flotation board that can pump air. However, the disadvantages of this method are also very obvious. For example, during the cutting process, if the glass needs to be moved, it is difficult to move the glass because the glass is completely in contact with the air flotation board (including the subsequent unloading of the glass, which is also troublesome. The glass is adsorbed on the board, and unloading is difficult). Secondly, the air flotation board method uses a seamless contact between the glass and the air flotation board, resulting in "adsorption force" between the thin glass and the air flotation board. During the cutting process, when the glass needs to be lifted up by air flotation, a greater air flotation force is required, resulting in too fast air flow speed. Different glasses have different weights. Once the air flow is not well controlled, the floating force is too small to lift the glass. If the floating force is too large, it is easy to float the glass too much and easily hit the cutting tool, causing glass damage. Utility Model Content

[0034] Example 1

[0035] like Figure 1-5 As shown, an ultra-thin glass transverse cutting device includes transverse cutting area beams 2 arranged at intervals on both sides, and a cutting area for placing ultra-thin glass is formed between the transverse cutting area beams 2.

[0036] At the same time, in order to solve the problem that the ultra-thin glass is difficult to move after being placed and cut, and to solve the defect that the glass is placed on a flat structure (such as an air floating plate, where the glass has a large adsorption force and is difficult to float), several support roller assemblies 4 for supporting the ultra-thin glass are assembled and connected between the cross beams 2 in the cross-cutting area, and the ultra-thin glass is placed on the top surface of the support roller assembly 4.

[0037] Specifically, the support roller assembly 4 includes a long rotating shaft 41 rotatably connected between the cross beams 2 in the cross-cutting area, and a plurality of support rollers 42 are rotatably connected to the long rotating shaft 41, and the ultra-thin glass is supported on the support rollers 42. The advantages of this method are: the glass support is placed on the support rollers 42, and the densely arranged support rollers 42 are used to effectively support the glass, and secondly, due to the gap between the glass and the support surface (the gap between the support rollers 42), it is convenient to float the glass easily and sensitively during air flotation, thereby greatly reducing the operability of thin glass during the cutting process.

[0038] In order to fully float the glass during the cutting process, the ultra-thin glass transverse cutting device further includes a plurality of air flotation mechanisms 3 disposed between the supporting roller 42 components 4, the air flotation mechanism 3 including an air flotation transverse tube 32, the air flotation transverse tube 32 being connected to an air flotation tube 31 located between the supporting roller 42 components 4 (the air flotation tube 31 is connected to the top of the air flotation transverse tube 32 and is located at the lower side of the supporting roller 42, and the layout during the design process is: supporting roller 42 component 4-air flotation mechanism 3-supporting roller 42 component 4... through this method, the glass is floated with a relatively uniform air flotation force). At the same time, an air inlet pipe is connected to the bottom of the air flotation transverse tube 32, and the air inlet pipe is connected to the air supply device in the conventional manner to supply air, and the gas is discharged from the air flotation tube 31, and forms air flotation force from bottom to top, and the air flotation force effectively forms a supporting force, ensuring that the glass is kept under relatively stable support during cutting, thereby improving the protection of the glass during the cutting process.

[0039] The two ends of the air-floating transverse tube 32 are respectively fixedly mounted on the cross-section area beam 2. Specifically, the two ends of the air-floating transverse tube 32 are respectively fixedly connected with L-shaped mounting plates 34, and the mounting plates 34 are fastened on the cross-section area beam 2.

[0040] Example 2

[0041] like Figure 1-5 As shown, based on the structure of Example 1, the ultra-thin glass transverse cutting device of this embodiment further includes a cutting mechanism 1 for cutting glass, wherein the cutting mechanism 1 is a conventional cutting device for cutting ultra-thin glass disclosed in the prior art, and its main structure includes a cutting knife holder 11, and a cutting assembly is assembled and connected to the cutting knife holder 11, and the cutting assembly includes a knife holder plate 12, which is the same as the existing method, and a cutting knife (not shown in the figure) for cutting glass is installed at the bottom of the knife holder plate 12. Specifically, the knife holder plate is moved by a drag chain on the cutting knife holder, which is the same as the existing method.

[0042] In order to keep the floating glass in the cutting process and to be able to be cut under a relatively stable contact pressure, and to increase the neatness of glass cutting and improve the cutting accuracy during the cutting process, the bottom of the above-mentioned knife holder plate 12 is equipped with a pressure wheel assembly for pressing the glass (the pressure wheel assembly is located at the bottom of the knife holder plate, and its connection position is not shown in the figure). The pressure wheel assembly includes a support 51 installed at the bottom of the knife holder plate 12 (the support 51 is fixed by welding), and a pressure wheel 52 is rotatably connected to the support 51. The material of the pressure wheel 52 is polyurethane material (polyurethane material is used for elastic contact and pressure on glass to protect the glass).

[0043] During the cutting process, when the glass is subjected to gas buoyancy, for the position where the glass floats up more (there is a large hollow distance between the supporting roller 42), the downward pressure of the pressure wheel 52 is used during the cutting process to keep the glass in a relatively stable supporting environment, thereby ensuring that the glass is not damaged during the cutting process. Specifically, during the cross-cutting process, the glass may have a phenomenon where the lower surface is higher than the supporting roller 42 due to the large gas buoyancy. At this time, the pressure wheel 52 will press it down, thereby ensuring the flatness of the upper surface of the glass during glass cutting.

[0044] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
