Description

Technical Field

[0001] The present invention relates to the technical field of production of microcrystalline glass, laminated glass, special glass, energy-saving glass and coated glass, and in particular to a production device and method for ultra-thin glass. Background Art

[0002] Generally, glass with a thickness of less than 1.1mm is called ultra-thin glass, among which UTG refers to ultra-thin flexible glass with a thickness of ≤0.1mm. Ultra-thin glass has excellent hardness, transparency, heat resistance, electrical insulation and flexibility, and has relatively stable mechanical and chemical properties in oxidation and light environments. It can be applied to microcrystalline glass, energy-saving glass, tablet computers, mobile phones, wearable devices, car displays, etc.

[0003] The traditional production method of ultra-thin glass is mainly chemical method. The chemical method targets the network structure of the glass and uses different acid solutions to etch the glass surface to reduce the thickness of the glass so that the thickness meets the requirements of ultra-thin glass. However, the chemical method has greater pollution during the production process, and the etching process is prone to produce pits on the glass surface; the second is physical method. This production method first heats and softens the glass, and then uses multiple sets of rollers to stretch and thin it. In the physical method, since multiple sets of rollers are required to cooperate with stretching and rolling, the matching accuracy between multiple sets of rollers is difficult to fully meet the requirements for the production of ultra-thin glass due to the limitations of the component manufacturing accuracy and assembly process of the equipment itself. In particular, the size of the 6th generation and above glass substrate is not less than 1500*1850 (mm). Traditional equipment is even more difficult to meet the requirements, resulting in uneven stretching of the softened glass when multiple sets of rollers stretch and thin the softened glass at the same time, resulting in poor flatness of the produced ultra-thin glass and the presence of a large number of microcracks.

[0038] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0039] Embodiment 1

[0040] Reference Figure 1-Figure 7 As shown, an ultra-thin glass production device of the present invention comprises:

[0041] A heating furnace 8 is used to heat and soften the glass to be processed 6, and is provided with a heating channel 9. The size of the heating channel 9 is not smaller than the glass to be processed 6. The glass to be processed 6 becomes softened glass after passing through the heating channel 9;

[0042] A clamping and conveying mechanism 2, which is arranged at the output end of the heating channel 9, and comprises a first telescopic driving member 21 and a clamping assembly, wherein the clamping assembly is connected to the output end of the first telescopic driving member 21, and the clamping assembly clamps the softened glass;

[0043] The rolling mechanism 3 is arranged on the side of the clamping assembly away from the heating channel 9. The softened glass is transmitted to the rolling mechanism 3 under the drive of the first telescopic driving member 21. The rolling mechanism 3 includes a first rotating driving member 33 and a pressure roller. The pressure roller is connected to the output end of the first rotating driving member 33. There are at least two pressure rollers, and a rolling channel 35 is formed between at least two of the pressure rollers. The thickness of the rolling channel 35 is less than the glass 6 to be processed.

[0044] The ultra-thin glass production equipment described in the present invention places the glass to be processed 6 into the heating channel 9 of the heating furnace 8, and heats the glass to be processed 6 by the heating furnace 8 to make it reach a softened state. When the glass to be processed 6 is softened, the clamping assembly of the clamping and conveying mechanism 2 is opened to clamp the softened glass, and the clamping assembly is driven downward by the first telescopic driving member 21 to transmit the softened glass from the heating furnace 8. The softened glass is pulled down to the rolling mechanism 3, and the first rotating driving member 33 drives the pressing roller to rotate. The softened glass passes through the rolling channel 35 under the squeezing action of the pressing roller and is pressed into ultra-thin glass. The ultra-thin glass processed by the rolling mechanism 3 is output from the rolling channel 35, thereby being pressed into ultra-thin glass.

[0045] Reference Figure 1-Figure 2 As shown, the length and width of the heating channel 9 inside the heating furnace 8 should be slightly larger than the size of the glass 6 to be processed, so that the glass can pass freely in the channel, and the heating elements are evenly distributed around the heating channel 9 to ensure uniform heating of the glass 6 to be processed. In addition, the heating furnace 8 is also equipped with a temperature control system, which monitors the temperature in the heating channel 9 in real time through a temperature sensor, and automatically adjusts the heating power according to the set temperature value to ensure that the glass 6 to be processed can be heated to a suitable softening temperature.

[0046] Reference Figure 2-Figure 4 As shown, the first telescopic driving member 21 can be installed on the frame below the heating furnace 8, and the clamping assembly can be composed of two or more clamping claws, which can be opened and closed by a driving device such as a cylinder or a hydraulic cylinder. When the glass needs to be clamped, the clamping claws are opened, the glass is placed between the clamping claws, and then the clamping claws are closed to clamp the glass. After the clamping assembly clamps the glass, the first telescopic driving member 21 drives the clamping assembly to move downward in the vertical direction.

[0047] Reference Figure 5 As shown, the first rotary drive member 33 of the rolling mechanism 3 is installed on the frame 1, and its output end is connected to the shaft of the pressure roller through a belt 34. The pressure roller adopts a cylindrical structure, and its surface is hardened. The thickness of the rolling channel 35 between the two pressure rollers can be achieved by adjusting the spacing between the pressure rollers to meet the production requirements of ultra-thin glasses of different thicknesses. When the softened glass is pulled down to the rolling mechanism 3 by the clamping conveying mechanism 2, the first rotary drive member 33 will drive the first pressure roller 31 and the second pressure roller 32 to rotate, and the softened glass will pass through the rolling channel 35 under the extrusion of the pressure roller, so as to be pressed into ultra-thin glass. In order to ensure the rotation accuracy and stability of the pressure roller, the first rotary drive member 33 is equipped with a reducer and an encoder.

[0048] Reference Figure 4As shown, the clamping assembly includes a clamping cylinder 26 and a clamping part 28. The end of the clamping cylinder 26 is also provided with a heat insulating part 27 to insulate the cylinder from the glass. The clamping cylinder 26 is connected to the output end of the first telescopic driving member 21, and the clamping part 28 is connected to the output end of the clamping cylinder 26. Each clamping assembly has at least two clamping parts 28, and at least two clamping parts 28 are respectively arranged on both sides of the thickness direction of the glass to be rolled. When the first telescopic driving member 21 moves the clamping cylinder 26 to the bottom of the heating furnace 8, the clamping cylinder 26 receives a clamping signal, and the piston rod extends. The extension movement of the piston rod pushes the clamping part 28 to move toward the glass to be rolled, so that at least two clamping parts 28 approach and contact the glass from both sides of the glass thickness direction, respectively. The clamping part 28 applies a clamping force to the glass to firmly clamp the glass. The first telescopic driving member 21 drives the clamping cylinder 26 and the clamped glass to move downward, and pulls the glass down to the rolling mechanism 3 for rolling processing. The clamping assembly maintains the glass clamping state until the rolling process is completed, the piston rod of the clamping cylinder 26 retracts, the clamping part 28 releases the glass, and continues to rise and clamp.

[0049] Reference Figure 5 As shown, the machine frame 1 is also included, and the rolling mechanism 3 includes at least a first rolling roller 31 and a second rolling roller 32. The first rolling roller 31 and the second rolling roller 32 are respectively rotatably connected to the machine frame 1. The output end of the first rotating driving member 33 is connected to the first rolling roller 31 and / or the second rolling roller 32. After the glass 6 to be processed passes through the heating furnace 8 and is softened, it is pulled down to the rolling mechanism 3 by the clamping and conveying mechanism 2. The first rotating driving member 33 drives the first rolling roller 31 and / or the second rolling roller 32 to rotate. The softened glass enters the rolling channel 35 between the first rolling roller 31 and the second rolling roller 32. As the rolling rollers rotate, the glass is gradually thinned under the squeezing action of the rolling rollers to form ultra-thin glass. In some embodiments, the first rolling roller 31 and the second rolling roller 32 are multiple groups to achieve a gradual thinning process.

[0050] Reference Figure 1 As shown, in order to improve the cleanliness of the rolling channel 35 and the die-cutting mechanism 4, sealing plates 12 are sealed around the frame 1, and transmission channels are respectively opened under the rolling channel 35 and the support plate 46. The clamping assembly is connected to the frame 1 through the second bracket 24. The frame 1 is also provided with a movably connected guide shaft 22 and a sleeve 23 sleeved on the guide shaft 22. The second telescopic drive member 25 is connected to the end of the guide shaft 22.

[0051] Reference Figure 4As shown, the output end of the first telescopic driving member 21 is connected to the second telescopic driving member 25, the clamping cylinder 26 is connected to the output end of the second telescopic driving member 25, the frame 1 is movably connected to the first bracket 313, the first pressing roller 31 is rotatably connected to the first bracket 313, the first bracket 313 moves in a direction perpendicular to the plane where the rolling space is located, the frame 1 is provided with a servo driving assembly 37, the first bracket 313 is connected to the output end of the servo driving assembly 37, when the first telescopic driving member 21 works, it drives the second telescopic driving member 25, the clamping cylinder 26 and the clamping part 28 to move up and down together. When clamping the glass, the positions of the clamping cylinder 26 and the clamping part 28 are adjusted by the second telescopic driving member 25 to make the clamping more accurate and stable. During the rolling process, according to the thickness requirement of the glass to be rolled, the servo drive assembly 37 is started to drive the first bracket 313 to move, and the first bracket 313 slides on the guide rail 39, and the servo drive assembly 37 drives the screw assembly 36, and the screw assembly 36 drives the first bracket 313 to move, and adjusts the distance between the first pressing roller 31 and the second pressing roller 32. When the distance is adjusted to a suitable value, the first rotary drive member 33 drives the first pressing roller 31 and the second pressing roller 32 to rotate, and the glass is rolled to be pressed into ultra-thin glass.

[0052] Reference Figure 5 As shown, a third telescopic driving member 312 is provided at one end of the first pressing roller 31, and a measuring sensor 310 is connected to the output end of the third telescopic driving member 312. A measuring disk 311 is provided at the end of the second pressing roller 32, and the measuring disk 311 is provided on the movement path of the measuring sensor 310. The first pressing roller 31 is also provided with a displacement sensor 38. Before the device is started, the third telescopic driving member 312 is actuated to push the measuring sensor 310 to move toward the measuring disk 311. When the measuring sensor 310 contacts the measuring disk 311, it indicates that the initial distance between the pressing rollers has been measured. During the glass rolling process, the displacement sensor 38 monitors the displacement of the first pressing roller 31 in real time. According to the data of the displacement sensor 38 and the measuring sensor 310, the control system can calculate the thickness of the glass, and adjust the parameters of the rolling mechanism 3, such as the pressure or spacing of the pressing rollers, according to the preset thickness value, so that the glass is pressed into a preset thickness.

[0053] Reference Figure 6-Figure 7As shown, a die-cutting mechanism 4 is arranged below the rolling mechanism 3, and the die-cutting mechanism 4 includes: a support plate 46, a fourth telescopic driving member 42, a fifth telescopic driving member 45, a first cutter 43, and at least two second cutters 44 arranged at intervals. The fourth telescopic driving member 42 is used to drive in the horizontal direction, the fifth telescopic driving member 45 is connected to the output end of the fourth telescopic driving member 42, and the first cutter 43 is connected to the output end of the fifth telescopic driving member 45. After the rolled glass comes out of the rolling channel 35, it falls on the support plate 46, and the thinned glass is supported by the support plate 46. The cutters are all arranged above the inclined surface of the support plate 46, and the glass falls naturally under the action of gravity. When the glass slides down, when it passes through the second cutters 44 arranged at intervals, its width is cut to the distance between the second cutters 44, and the first cutter 43 is driven to move toward the glass by the fifth telescopic driving member 45. When moving to the die-cutting position, the fourth telescopic drive member 42 drives the first cutter 43 to move in the horizontal direction for horizontal cutting. The height of the first cutter 43 can be controlled through the two-axis adjustment component 41 and the movable range of the fourth telescopic drive member 42 can be further increased. Since the device no longer performs a stretching drive action after the glass softens, there is no need to cool the ultra-thin glass to make it thinner and more stable after stretching, which reduces the shaping process and omits the glass cooling step for direct die-cutting, thereby increasing production efficiency. In addition, die-cutting is performed when the glass is softened, making it easier to cut ultra-thin glass and greatly reducing the stretching effect of the cutter on the glass.

[0054] The extension direction of the support plate 46 and the plane where the rolling channel 35 is located have an angle, so that the ultra-thin glass slides down along the surface of the support plate 46 after being output from the rolling channel 35. When the first cutter 43 and the second cutter 44 die-cut the ultra-thin glass, the ultra-thin glass can always adhere to the surface of the support plate 46 under the action of gravity, and will not float in the horizontal direction. The angle is an acute angle. In this embodiment, the angle is 10°-45°, preferably 13°, which can ensure that the ultra-thin glass slides down against the support plate 46, and at the same time avoid the formation of sliding scratches caused by excessive force on the surface of the support plate 46 due to excessive inclination angle.

[0055] Continue to refer to Figure 6-Figure 7 As shown, at least two of the second cutters 44 are slidably connected to the guide rail 39, and the clamping assemblies are at least two and are respectively arranged on both sides of the glass to be softened, thereby reducing the processing error and defective rate caused by the shaking of the glass. The projection area of ​​at least two of the second cutters 44 along the vertical direction is located within the projection area of ​​the clamping assembly along the vertical direction, so that the softened glass clamped by the clamping assembly is cut and removed, and the clamping marks left on the softened glass by the clamping portion 28 are prevented from affecting the smoothness of the glass.

[0056] The first cutter 43 and the second cutter 44 can be rotatably arranged respectively so that the axis of the first cutter 43 and the second cutter 44 is perpendicular to the plane of the support plate 46. Before the die-cutting mechanism 4 starts working, the equipment control system or manually determines the appropriate rotation angle of the first cutter 43 and the second cutter 44 according to the parameters of the glass to be cut and the cutting requirements, and sends a command to the rotation drive device. The first cutter 43 and the second cutter 44 are rotated to the angle. When the glass enters the die-cutting mechanism 4 and reaches the cutting position, the fourth telescopic drive member 42 and the fifth telescopic drive member 45 push the first cutter 43 to cut horizontally, and at least two second cutters 44 slide in the vertical direction relative to the glass to cut the glass. Since the axis of the first cutter 43 and the second cutter 44 is perpendicular to the plane of the support plate 46, the cut seam of the glass is flush.

[0057] Reference Figure 1-Figure 2 As shown, a hoisting mechanism is provided on one side of the heating channel 9, and the hoisting mechanism includes: a second rotary drive member 10, a guide frame 7, a rope 11 and a clamp 5. The first end of the rope 11 is wound around the second rotary drive member 10, and the second end is connected to the clamp 5. The clamp 5 is fixedly connected to the top of the glass to be processed 6. When the glass to be processed 6 is loaded, the clamp 5 is fixedly connected to the top of the glass to be processed 6. The second rotary drive member 10 is started, and the drum of the second rotary drive member 10 starts to rotate and the rope 11 is wound. Under the guidance of the guide frame 7, the rope 11 can pull the clamp 5 and the glass to be processed 6 up and down, and the glass to be processed 6 is hoisted and moved to the top of the heating channel 9. By controlling the rotation direction of the second rotary drive member 10, the glass to be processed 6 is slowly placed into the heating channel 9 to complete the loading process.

[0058] The input side and output side of the heating channel 9 are respectively provided with limit assemblies, and the limit assemblies include limit plates arranged at intervals, and the spacing of the limit plates is adapted to the thickness of the glass 6 to be processed. When the glass 6 to be processed enters the heating channel 9, it first passes through the limit assembly on the input side. The glass 6 to be processed enters the heating channel 9 under the guidance of the limit plates. During the heating process, the limit assembly can limit the horizontal movement of the glass to ensure that the position of the glass in the heating channel 9 is stable. When the heating is completed, the glass passes through the limit assembly on the output side and is aligned for subsequent rolling. The two limit plates have relatively expanded openings for guidance.

[0059] Embodiment 2

[0060] This embodiment provides a method for producing ultra-thin glass, which is produced using an ultra-thin glass production device as described in the embodiment, and includes the following steps:

[0061] Step S: providing a glass to be processed 6 and presetting the thickness of the rolling channel 35;

[0062] Step S: passing the glass to be processed 6 through the heating channel 9 to heat and soften it;

[0063] Step S: pulling the softened glass downward under the heating channel 9 to allow the softened glass to enter the rolling channel 35 downward;

[0064] Step S: rolling the softened glass to reduce the softened glass thickness to a preset thickness.

[0065] The method for producing ultra-thin glass of the present invention is as follows: according to the thickness requirement of the ultra-thin glass to be produced, the thickness of the rolling channel 35 in the rolling mechanism 3 is preset, and the glass to be processed 6 is placed in the heating channel 9 of the heating furnace 8. The heating furnace 8 heats and softens the glass to be processed 6, so that the physical properties of the glass change, gradually changing from a hard solid state to a soft plastic state, and the clamping cylinder 26 of the clamping assembly is actuated to clamp the heated and softened glass. The first telescopic driving member 21 is started, and the movement of its output end drives the clamping assembly and the softened glass to move downward in the vertical direction, so that the glass can enter the rolling channel 35 of the rolling mechanism 3, and the softened glass is rolled by the rolling mechanism 3. The first rotating driving member 33 drives the pressing roller to rotate, and when the softened glass enters the rolling channel 35, it is squeezed by the pressing roller. Since the thickness of the rolling channel 35 is less than the original thickness of the glass 6 to be processed and has been pre-set to the thickness of the required ultra-thin glass, the thickness of the softened glass is reduced to the preset ultra-thin glass thickness under the continuous squeezing of the pressure roller, and can be used to provide a glass substrate for laminated glass, energy-saving glass and coated glass.

[0066] In daily life, glass can be divided into six types according to its thickness: extra thick glass 19-30mm; ultra-thick glass 12-19mm; thick glass 8-12mm; ordinary flat glass 4-8mm; thin glass 1.1-3mm; ultra-thin glass <1.1mm, among which UTG refers to ultra-thin flexible glass with a thickness of ≤0.1mm and has bendable properties. The raw glass to be processed in this embodiment is thin glass or ordinary flat glass, which is softened and rolled to form ultra-thin flexible glass.

[0067] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
