Description

Technical Field

[0001] This invention belongs to the field of ultra-thin electronic glass processing technology, specifically relating to a cutting system and method for ultra-thin electronic glass. Background Technology

[0002] Ultra-thin electronic glass refers to special glass with a thickness typically between 0.1 and 2 mm. It has characteristics such as high light transmittance, high hardness, and bendability, and is therefore widely used in foldable screen mobile phones, tablets, automotive displays, smart wearable devices, rollable TVs, flexible medical testing equipment, semiconductor packaging, and solar cells.

[0003] When producing 0.20-0.33mm ultra-thin electronic glass using the float glass process, the formed continuous glass strip undergoes annealing, followed by longitudinal cutting, transverse cutting, horizontal bending, edge cleaning, branch line breaking, and paper laying before stacking and packaging. During this process, the glass completes these operations while running on roller conveyors. However, currently, the online cutting of 0.20-0.33mm ultra-thin glass still uses traditional mechanical cutting methods. But as the glass thickness decreases, its strength decreases and its flexibility increases, meaning the glass itself lacks sufficient strength to exert a reaction force on the cutting wheel during online cutting. Therefore, as the glass thickness decreases, the cutting force range of the cutting wheel becomes very narrow, increasing the difficulty of cutting. Furthermore, when the cut glass is broken, it is prone to cracking outside the cut line or failing to break completely. Therefore, the cutting process for ultra-thin electronic glass must be researched and optimized to achieve good cutting results.

[0004] Chinese patent CN214032242U discloses a tempered glass cutting mechanism, including a worktable, a conveyor belt disposed above the worktable, and a cutting area disposed to the right of the conveyor belt; the cutting area includes a shock-absorbing device connected to the upper surface of the worktable and a collecting device below it; the shock-absorbing device includes a shock-absorbing block connected to the conveyor belt, the shock-absorbing block being connected to a shock-absorbing plate, a limiting block being attached to the right end of the shock-absorbing plate, and a fiber mat being connected to an elastic drum; the surface of the shock-absorbing block is designed with a 55-60° bevel; the cutting device includes a blade holder and a cutting blade, the cutting blade including a thin glass cutting blade and a thick glass cutting blade, the tip angle of the thin glass cutting blade wheel being designed to be 110°. The apex angle of the thick glass cutting blade is designed to be 140° (115°). 145°. This mechanism can adapt to cutting glass of varying thicknesses, reducing vibrations during glass transport and preventing breakage. However, it is designed for tempered glass and is not suitable for ultra-thin electronic glass with significantly increased flexibility. Furthermore, it directly cuts the glass into two separate pieces, eliminating the issue of low yield rates due to glass breakage.

[0005] Chinese patent CN221094030U discloses an auxiliary device for horizontally bending ultra-thin float glass. The device includes a horizontal drive unit fixed to a support frame; a vertical drive unit fixed to the output end of the horizontal drive unit; a pressure roller assembly fixed to the output end of the vertical drive unit, positioned above a transmission track for transporting the ultra-thin float glass, on which the ultra-thin float glass is movably mounted; and a control system electrically connected to the horizontal and vertical drive units. This application solves the problem of large wave deformation in the horizontal cutting area of ​​float glass, resulting in a more uniform cutting depth when the blade cuts through the ultra-thin float glass. This leads to a smoother surface in the cutting area, avoiding increased losses due to multiple chipped corners after horizontal bending, and effectively reducing defects caused by horizontal bending. However, it flattens the glass before cutting to avoid uneven cutting depth and low yield after horizontal bending, rather than directly bending the ultra-thin float glass. The cutting process still suffers from low cutting force, difficulty in horizontal bending, and low yield.

[0006] Therefore, it is necessary to develop a cutting system suitable for ultra-thin electronic glass to achieve controlled cutting and controlled lateral bending of flexible glass, thereby improving the glass yield. Summary of the Invention

[0017] In a further preferred embodiment, the second cutter holder is connected to the cross-cutting bridge system via a fixing hole. A belt drives the second cutter holder to move from one side to the other, thus cutting the glass. Simultaneously, the cross-cutting bridge system also includes a safety door, fixed to a bracket and a fixed aluminum plate, which is fixedly connected to the crossbeam. A safety door sensor is located at the top of the safety door. The belt is connected to a tension adjustment module. A limit switch is installed on the crossbeam to limit the position of the cutting system. The cross-cutting bridge system also includes a cylinder and an electrical sensor to monitor the glass position and control the lifting and lowering speed and position of the cutter holder.

[0018] More preferably, the limiting shaft is provided with a pin limiting hole and an external spring; the spring is in contact with the ball; the ball is located in the ball receiving cavity, which is located in the second tool holder, and the ball receiving cavity is connected to the oil port.

[0019] More preferably, the pin is inserted into the pin receiving cavity, passes through the gap of the spring, and reaches the pin limiting hole to fix the first tool holder to the second tool holder.

[0020] More preferably, the lubricating oil is added through the oil port, and the lubricating oil is delivered to the ball bearing cavity. The rotation of the balls delivers the lubricating oil to the oil passage of the tool holder, and then to the oil passage in the tool post to lubricate the tool wheel.

[0021] Preferably, the transverse bending system includes a cylinder and a pressure system; the pressure system includes a crossbeam, which is fixedly connected to an adjusting slide groove, and the adjusting slide groove is slidably connected to a position adjusting plate; the position adjusting plate is fixedly connected to a connecting member, and the connecting member is fixedly connected to a pressure roller.

[0023] More preferably, the cylinder is located at the bottom of the conveyor belt, which can reduce damage to the glass while effectively lifting it, thereby improving the yield.

[0024] Furthermore, the horizontal breaking system can be set up in multiple groups to apply pressure to the glass at multiple points, thereby improving the breaking effect and the yield rate.

[0025] In a further preferred embodiment, the position of the pressure system remains fixed, and pressure is applied to both sides of the glass cutting position by the lifting and retraction of the cylinder to complete the horizontal bending.

[0026] Preferably, the conveying system includes a servo motor, a belt, a rotating shaft, and a transmission shaft. The servo motor drives the rotating shaft and the transmission shaft to rotate, thereby moving the belt and conveying the glass on the belt through the cutting system and the horizontal bending system to cut the glass.

[0027] This invention also provides a method for cutting ultra-thin electronic glass, comprising the following steps: S1: The glass is placed on the conveying system and transported to the cutting system for cutting; S2: After cutting, the glass is transported to the horizontal bending system through the conveying system, and pressure is applied to horizontally bend it to obtain the segmented ultra-thin electronic glass.

[0029] Preferably, the applied pressure in step S2 is 370-360N.

[0030] Preferably, depending on the requirements of the glass cutting direction and the size of the finished product, the cutting system and the horizontal bending system can be set in multiple sets in the horizontal and vertical directions to achieve multiple horizontal and vertical cuts of the glass.

[0031] The beneficial effects of this invention are as follows: 1. Using a V-shaped gear cutting wheel as the cutting tool avoids slippage during glass cutting, ensuring the continuity and uniformity of the cutting line and strong penetration. Simultaneously, the V-shaped gear prevents deep vertical cracks from forming during glass cutting, avoiding damage to the glass's strength. Furthermore, the number of gears ensures continuous cutting of the glass, reducing damage to the glass edges.

[0032] 2. A spring-loaded blade holder structure is used to cut ultra-thin electronic glass, adapting to the glass's characteristics of being thick at the edges, extremely thin in the middle, with large thickness differences, severe warping, and even exhibiting wavy edges. When the ultra-thin electronic glass cannot fully conform to the transverse cutting rollers, the spring-loaded blade holder structure ensures the blade wheel is firmly attached to the surface of the ultra-thin electronic glass, thereby improving cutting force and stability, as well as cutting efficiency and accuracy. Simultaneously, by controlling the pressure applied to the blade holder, glass cracking can be prevented, resulting in excellent cutting effects.

[0033] 3. By adopting a horizontal bending system, downward pressure is applied while the glass is being lifted, reducing the difficulty of horizontal bending and thus improving the yield of glass products. Attached Figure Description

Detailed Implementation

[0046] The technical solution of the present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments. It is worth noting that the following embodiments are only preferred embodiments of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention should be determined by the contents of the claims. Modifications and substitutions made by those skilled in the art to the technical solution of the present invention without creative effort all fall within the scope of protection of the present invention.

[0047] Example 1 like Figure 1-9 As shown, a cutting system for ultra-thin electronic glass includes a conveying system 1, a cutting system 3 fixed on the conveying system 1, and a horizontal bending system 4. The cutting system 3 includes a cutter wheel 301, which is fixed on a cutter holder 302. The cutter holder 302 is connected to a first cutter seat 304, and the first cutter seat 304 is connected to a second cutter seat 305. The cutter wheel 301 and other structures are fixed on a mobile device containing a cylinder and a belt through the second cutter seat 305, which drives the cutter wheel 301 to move from one side to the other to cut the glass 2.

[0048] Preferably, the cutter wheel 301 includes a cutter wheel base 3011, on which a mounting hole 3012 and a gear 3013 are provided. The gear 3013 directly contacts the glass 2 to complete the cutting action.

[0049] More preferably, the gear 3013 has an angle of 100-110° and a number of 350-500 teeth; the gear is V-shaped, which avoids the phenomenon of blade slippage during glass cutting, and can ensure the continuity and uniformity of the cutting line, and has strong penetration.

[0050] More preferably, the cutter wheel 301 is a diamond cutter wheel.

[0051] Preferably, the tool holder 302 includes a tool holder base 3021, on which an oil passage 3023, a tool shaft mounting hole 3022, and an auxiliary shaft 3024 are provided. The oil passage 3023 allows lubricating oil to pass through and lubricate the tool wheel mounted on the tool holder 302 during the glass 2 cutting process. The auxiliary shaft 3024 helps the tool holder 302 to be better installed and removed from the first tool holder 304. The tool shaft mounting hole 3022 can accommodate the tool shaft 303 and fix the tool wheel 301, wherein the shape of the tool shaft mounting hole 3022 is adapted to the shape of the tool shaft 303.

[0052] More preferably, the cutter shaft 303 passes through the cutter shaft mounting hole 3022 on the cutter holder 302 and the mounting hole 3012 on the cutter wheel 301, fixing the cutter wheel 301 on the cutter holder 302. Finally, the cutter holder is placed in the corresponding position of the first cutter seat 304. The closed structure on both sides can block the cutter shaft 303 to prevent it from shifting during the cutting process, thereby affecting the cutting effect.

[0053] More preferably, the cutter shaft 303 is a cylinder with one end thick and the other end thin and pointed, thereby fixing the cutter wheel 301 on the cutter holder 302 and preventing it from easily coming off, thus facilitating subsequent installation, use and disassembly.

[0054] Preferably, the first tool holder 304 includes a first tool holder base 3041, one end of which is provided with a tool holder mounting port 3042 for accommodating a tool holder 302 and sealing the tool shaft 303 in the tool shaft mounting hole 3022; the other end is fixedly connected to a limiting shaft 3043, and the limiting shaft 3043 and the first tool holder base 3041 are provided with a tool holder oil passage 3044 for conveying lubricating oil; the second tool holder 305 includes a second tool holder base 3051, the second tool holder base 3051... The end is provided with a limiting piece 3052 to prevent foreign objects from entering between the first cutter holder 304 and the second cutter holder 305, and at the same time to prevent internal structures such as springs 3046 from falling off or shifting abnormally; the inside is provided with a pin receiving cavity 3055 to receive the pin, so that the first cutter holder 304 is fixed in the second cutter holder 305; the outside is provided with a fixing hole 3054, so that the second cutter holder 305 can be connected to a moving device such as a cylinder, so that the cutter holder moves with the movement of the external device, thereby achieving linear cutting of glass.

[0055] More preferably, there are multiple fixing holes 3054 in different positions, which can fix the second cutter holder according to different cutting requirements, so as to achieve effective cutting of different types of glass.

[0056] In a further preferred embodiment, the second cutter holder 305 is snapped onto the cross-cutting bridge system 5 through a fixing hole 3054, and is driven by a belt 503 to move from one side to the other to cut the glass. Simultaneously, the cross-cutting bridge system 5 is also equipped with a safety door 509, which is fixed to the bracket 6 and the fixing aluminum plate 504, and the fixing aluminum plate 504 is fixedly connected to the crossbeam 501. A safety door sensor 502 is provided at the top of the safety door 509. The belt 503 is connected to a tension adjustment module 505. A limit switch 508 is provided on the crossbeam 501 to limit the position of the cutting system 3. The cross-cutting bridge system 5 is also equipped with a cylinder and an electrical sensor to monitor the glass position and control the lifting and lowering speed and position of the cutter holder.

[0057] More preferably, the limiting shaft 3043 is provided with a pin limiting hole 3045. When the first tool holder 304 is inserted into the second tool holder 305 and needs to be fixed, the pin is inserted from the pin receiving cavity 3055, passes through the spring 3046, and enters the pin limiting hole 3045, fixing the first tool holder 304 inside the second tool holder 305. An external spring 3046 is provided; the contraction of the spring 3046 can cause a certain displacement of the first tool holder 304, playing a shock-absorbing role. The spring 3046 contacts the ball bearing 3047, which is located in the ball bearing receiving cavity 3056, which is located in the second tool holder 305. The ball bearing receiving cavity 3056 communicates with the oil port 3053 for lubrication. Lubricating oil enters through oil port 3053 and is delivered to the ball bearing cavity 3056, where it contacts the balls. The movement of the balls 3047 delivers the lubricating oil through the cutter holder oil passage to the cutter wheel 301. Then, the cutter wheel 301 rotates, causing the lubricating oil to be located between the cutter wheel 301 and the glass 2, thus lubricating the glass cutting. The displacement distance between the first cutter holder 304 and the spring 3046 is 1-1.1 mm. Therefore, the diameter of the pin limiting hole 3045 is 1-1.1 mm wider than the diameter of the pin end. At the same time, the pitch of the spring 3046 is equal to the pin diameter plus the displacement distance (1-1.1 mm) to ensure that the spring 3046 and the first cutter holder 304 have a certain displacement space, thereby ensuring a certain shock absorption effect.

[0058] More preferably, the pin is inserted into the pin receiving cavity 3055 and passes through the gap of the spring 3046 to reach the pin limiting hole 3045, fixing the first cutter holder 304 onto the second cutter holder 305. At the same time, the first cutter holder 304 is allowed to have a certain vertical displacement space, so that the cutter wheel 301 is properly and firmly close to the surface of the object being cut during the cutting process. This avoids the cutter wheel 301 being unable to make effective cuts due to the warping of the glass 2, which would affect the horizontal bending effect and yield. It also buffers the impact force between the cutter wheel 301 and the glass 2, reducing the wear and loosening of the cutter wheel 301 during cutting.

[0059] More preferably, by adding lubricating oil through the oil port 3053, the lubricating oil is delivered to the ball receiving cavity 3056, and the rotation of the ball 3047 delivers the lubricating oil to the tool holder oil passage 3044, and then to the oil passage 3023 in the tool holder 302 to lubricate the tool wheel 301.

[0060] Preferably, the horizontal bending system 4 includes a cylinder 401 and a pressure system 402; the pressure system 402 includes a crossbeam 4023, which is fixedly connected to an adjusting slide 4022, and the adjusting slide 4022 is slidably connected to a position adjusting plate 4021; the position adjusting plate 4021 is fixedly connected to a connecting member 4024, and the connecting member 4024 is fixedly connected to a pressure roller 4025. Pressure is applied to the adjusting slide 4022 by the fixed crossbeam 4023, thereby applying pressure to the pressure roller 4025 by the position adjusting plate 4021 and the connecting member 4024, thereby applying pressure to both sides of the cutting mark on the glass 2, and simultaneously lifting the cutting position of the glass 2 in coordination with the movement of the cylinder 401, thus completing the horizontal bending.

[0061] More preferably, there are at least two sets of the position adjustment plate 4021, the connecting member 4024 and the pressure roller 4025, and the distance between the two sets of pressure rollers and the cutting marks of the glass 2 is 300-500mm, so that pressure can be applied to both sides of the cutting marks of the glass 2 to achieve horizontal bending.

[0062] More preferably, the cylinder 401 is located at the bottom of the belt of the conveyor system 1, which can reduce damage to the glass while effectively lifting it, thereby improving the yield.

[0063] More preferably, the horizontal breaking system 4 can be set in multiple groups to apply pressure to the glass 2 at multiple points, thereby improving the breaking effect and yield. The horizontal breaking system 4 is 15-25mm away from the glass surface, so as to ensure that it does not put pressure on the glass under normal conditions, but can apply pressure to both ends of the glass when the cylinder 401 is lifted.

[0064] In a further preferred embodiment, the position of the pressure system 402 remains fixed. When the cutting position of the glass 2 is transmitted to the cylinder 401, the cylinder 401 lifts the glass on the belt, thereby applying pressure to both sides of the glass cutting position to complete the horizontal bending. After the horizontal bending is completed, the cylinder 401 retracts, and the belt and glass fall down together. With the movement of the belt, the glass 2 is conveyed to the next process.

[0065] Preferably, the conveying system 1 includes a servo motor, a belt, a rotating shaft, and a transmission shaft. The servo motor drives the rotating shaft and the transmission shaft to rotate, thereby moving the belt and conveying the glass 2 on the belt through the cutting system 3 and the horizontal bending system 4 to cut the glass.

[0066] Preferably, one end of the conveying system 1 can be directly connected to the glass annealing furnace, and the other end can be directly connected to a stacking system, etc., to perform automated assembly line processing on the glass 2.

[0067] Example 2 S1: A 0.1mm thick glass 2 is placed on the conveying system 1 and transported to the cutting system 2. When the glass reaches the corresponding position, the second cutter holder 305 and the first cutter holder 304 drive the cutter wheel 301 to cut at a speed of 30mm / s from 10mm away from the edge of the glass. The cutter wheel 301 is also driven to move from one side of the glass to the other side, and then lifted at the other side of the glass, 10mm away from the edge, at a lifting speed of 30mm / s. The computer automatically adjusts the moving speed of the cutter wheel according to the speed of the glass belt to complete the cutting. The gear 3013 in the cutting system 2 has 400 teeth and an angle of 105°. The pressure applied by the cutting system to the cutter wheel ranges from 4.7 to 6.5N. S2: After cutting, the glass is conveyed to the horizontal bending system 4 via the conveying system 1. By calculating the conveying speed of the servo motor, when the cutting mark moves to the top of the cylinder 401 in the horizontal bending system 4, the cylinder 401 is controlled to lift up, thereby lifting the glass along the cutting mark. Then, pressure is applied to both sides of the cutting mark through the pressure system, thereby achieving the horizontal bending of the glass 2. The horizontally bent glass is then conveyed to the next process, which can be cutting in another direction, or laying paper and stacking. When the cylinder 401 is ±5mm away from the cutting mark, the cylinder 401 lifts up to a height of 60mm, the lifting time is 200ms, and the falling time is 250ms.

[0068] The servo motor has a transmission speed of 10-90m / min, and the installation angle of the cutting system 3 is 4-7.2°, ensuring that the glass can be cut in a straight line without stopping the transmission.

[0069] The yield rate for cut glass is 50%.

[0073] The yield rate of cut glass was 57%, with 2% of the glass being broken into crooks and 2% being broken pieces.

[0074] Comparative Example 1 The method and steps are the same as in Example 2, except that the cutting and lifting positions are changed to 40mm away from the edge of the glass to complete the glass cutting.

[0075] The yield rate of cut glass was 58%, with 2% of the glass being broken into crooked pieces and 1% being broken fragments.

[0076] Comparative Example 2 The method and steps are the same as in Example 2, except that the speed of the blade during cutting is changed to 10 mm / s to complete the glass cutting.

[0077] The yield rate of cut glass is 60%, and the percentage of broken glass is 1%.

[0078] Comparative Example 3 The method and steps are the same as in Example 2, except that the speed of the blade during cutting is changed to 50 mm / s to complete the glass cutting.

[0079] The yield rate of cut glass was 57%. In addition, 2% of the glass was broken into crooked pieces, 1.5% was broken pieces, and 0.5% was chipped.

[0080] Comparative Example 4 The method and steps are the same as in Example 2, except that the first and second cutter holders in the cutting system are changed to a rigid connection without springs for shock absorption, thus completing the glass cutting.

[0081] The yield rate of cut glass was 21%. In addition, 20% of the glass was broken into crooks, 9% was broken into pieces, 8% was not completely cracked, and 3% had missing corners.

[0082] Comparative Example 5 The method and steps are the same as in Example 2, except that the gear in the cutting wheel of the cutting system is changed from V-shaped to U-shaped, while the number of teeth and the angle remain unchanged, to complete the glass cutting.
