Description

Technical Field

[0001] This invention relates to the field of chemical tempering technology, and more particularly to a production line for chemically tempered glass. Background Technology

[0002] Chemical tempering is an important process widely used to enhance the mechanical strength and impact resistance of glass. Its basic principle is to introduce larger cations (such as K+) into the glass surface through an ion exchange process. + ), replacing smaller cations (such as Na) that were originally present in the glass network. + This process creates a compressive stress layer on the glass surface, significantly improving its strength, scratch resistance, and thermal shock resistance. Currently, the most commonly used chemical tempering method in industry is the immersion method, which involves completely immersing the glass to be treated in a high-temperature molten potassium salt (such as potassium nitrate or a mixture of potassium nitrate and sodium nitrate) solution, where the ion exchange reaction is completed under certain temperature and time conditions.

[0003] However, with the rapid growth in demand for high-strength, ultra-thin glass in consumer electronics, automotive displays, and architectural safety glass, the traditional immersion method has gradually revealed many insurmountable technical bottlenecks in actual industrial production. First, the immersion method requires a large amount of molten salt, which not only consumes a lot of raw materials and energy, but also makes waste salt difficult to dispose of, posing a risk of environmental pollution. Second, prolonged immersion of glass in molten salt can easily lead to edge corrosion, surface contamination, or uneven ion exchange. Third, this process has a long cycle, requires a large equipment footprint, and has limited automation, which is not conducive to achieving high-efficiency automatic tempering of glass.

[0004] To overcome these limitations, the industry has been exploring alternative ion exchange methods. While preliminary research has been conducted on the idea of ​​coating potassium salts onto the glass surface in solution followed by heat treatment, current technology lacks highly integrated production lines to match this approach. This makes it difficult to achieve uniform and controllable ion exchange, resulting in unstable tempering effects and failing to meet the stringent requirements of high-end applications for glass strength consistency and reliability.

[0005] Therefore, there is an urgent need to develop a new type of equipment for chemically tempered glass that can avoid the inherent defects of the traditional immersion method and ensure that the ion exchange process is efficient, uniform and controllable, so as to meet the needs of continuous and intelligent manufacturing of chemically tempered glass.

Detailed Implementation

[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] This technical solution provides a production line for chemically tempered glass, including a key breaking device 1, an attachment device 2, a chemical tempering device 3, a cooling device 4, and a cleaning device 5 connected in sequence. The key-breaking device 1 is used to break the bonds on the surface of the glass 6 to be tempered. The attachment device 2 is used to attach alkali metal salts to the surface of the glass 6 to be tempered. The chemical tempering device 3 is used to perform an ion exchange reaction on the surface of the glass 6 to be tempered. The cleaning device 5 is used to clean residual alkali metal salts on the surface of the glass 6.

[0027] To avoid the inherent defects of traditional immersion methods and ensure that the ion exchange process is efficient, uniform, and controllable, thereby meeting the needs of continuous and intelligent manufacturing of chemically tempered glass, this technical solution proposes a production line for chemically tempered glass, such as... Figure 1As shown, the production line includes a bond-breaking device 1, an attachment device 2, a chemical tempering device 3, a cooling device 4, and a cleaning device 5 connected in sequence. The production line process of this solution includes: first, the glass 6 is subjected to bond-breaking treatment by the bond-breaking device 1; then, alkali metal salts are attached to the surface of the glass 6 to be tempered by the attachment device 2; then, the glass with alkali metal salts attached to its surface is sent to the chemical tempering device 3 for ion exchange; after the ion exchange is completed, the glass 6 is cooled by the cooling device 4 and cleaned by the cleaning device 5, thus achieving the chemical tempering of the glass.

[0028] Currently, the most commonly used chemical tempering method in industry is the immersion method. This solution attaches alkali metal salts to the surface of glass 6 and performs subsequent ion exchange. It also designs a highly integrated production line that matches the above chemical tempering steps, which is conducive to achieving uniform adhesion of alkali metal salts on the glass surface and controllable ion exchange, thereby improving the chemical tempering effect of the glass and meeting the requirements for high-efficiency automatic tempering of glass, thus overcoming the shortcomings of the existing technology.

[0029] It should be noted that adjacent devices in the production line can be connected end-to-end via conveyor lines, robotic arms, etc., but this is not limited to this in this case. The alkali metal salts in this scheme refer to cations smaller than those originally present on the glass surface (such as Na). + Large cations (such as K) are required. + This process aims to introduce larger cations to replace the smaller cations that were originally present on the glass surface.

[0030] To further explain, the chemical tempering device 3 includes a first elevator 31, a tempering furnace 32, and a second elevator 33 connected end to end in sequence; The first elevator 31 includes a frame 311 and a conveyor roller assembly 312. The conveyor roller assembly 312 is vertically mounted on the frame 311. The conveyor roller assembly 312 includes a receiving bracket 3121 and a plurality of transfer rollers 3122. The plurality of transfer rollers 3122 are rotatably mounted on the receiving bracket 3121 at intervals. The transfer rollers 3122 are used to receive and deliver glass 6 in the horizontal direction. The first elevator 31 and the second elevator 33 have the same structure; The tempering furnace 32 includes a furnace body 321 and a tempering component 322. Multiple sets of tempering components 322 are provided and are installed in layers at intervals inside the furnace body 321. A first material receiving port 3211 and a second material receiving port 3212 are respectively opened at both ends of the furnace body 321. The conveying roller assembly 312 of the first elevator 31, the first material receiving port 3211 and one end of the tempering component 322 are interconnected. The other end of the tempering component 322, the second material receiving port 3212 and the conveying roller assembly 312 of the second elevator 33 are interconnected. The tempering assembly 322 includes a plurality of conveying rollers 3221 and a plurality of infrared heating tubes 3222; the plurality of conveying rollers 3221 are rotatably and spaced apart inside the furnace body 321, and the conveying rollers 3221 are used to convey glass 6 in the horizontal direction; the plurality of infrared heating tubes 3222 are spaced apart above the conveying rollers 3221 in the horizontal direction.

[0031] To ensure the smooth progress of the ion exchange reaction of glass 6 with alkali metal salts adhering to its surface, this scheme also optimizes the structure of the chemical tempering device 3, such as... Figure 2-6 As shown, the key structural tempering components 322 for realizing the ion exchange process are stacked, which greatly saves the space occupied by the tempering furnace 32. Each layer of tempering components 322 extends horizontally, and the glass 6 is continuously transported between each layer of tempering components 322 by the first elevator 31 and the second elevator 33 set at both ends of the tempering furnace 32, thereby meeting the continuous and automated production requirements of the chemical tempering process.

[0032] In one specific embodiment, the working process of the chemical tempering device 3 of this solution includes: Glass 6 is fed from the first elevator 31 and enters the conveying surface of the conveying roller 3221 in the bottom tempering component 322 through the forward rotation of the transfer roller 3122 and the corresponding first receiving port 3211. While the glass 6 is being conveyed by the conveying roller 3221 in the bottom tempering component 322, it is subjected to the heat radiation of the infrared heating tube 3222 of that layer, thereby realizing the ion exchange process.

[0033] When the glass 6 is conveyed to the end of the tempering component 322 at the bottom layer, the glass 6 leaves the tempering furnace 32 through the second receiving port 3212 and is received by the forward rotating transfer roller 3122 in the second elevator 33. After the glass 6 is completely received by the transfer roller 3122 in the second elevator 33, the second elevator 33 rises to the outside of the second receiving port 3212 corresponding to the second-to-last tempering component 322.

[0034] Then, the transfer roller 3122 in the second elevator 33 rotates in the opposite direction and sends out the glass 6, so that the glass 6 enters the tempering furnace 32 again through the corresponding second receiving port 3212 and is conveyed to the conveying surface of the conveying roller 3221 in the penultimate tempering component 322; while the conveying roller 3221 in the penultimate tempering component 322 is conveying, the glass 6 is subjected to the heat radiation of the infrared heating tube 3222 of that layer, thereby realizing the ion exchange process.

[0035] When the glass 6 is conveyed to the end of the tempering component 322 located on the second-to-last layer, the first elevator 31 has risen to the outside of the first receiving port 3211 corresponding to the second-to-last tempering component 322. The glass 6 leaves the tempering furnace 32 through the first receiving port 3211 and is received by the reverse rotating transfer roller 3122 in the first elevator 31. When the glass 6 is completely received by the transfer roller 3122 in the first elevator 31, the first elevator 31 rises to the outside of the first receiving port 3211 corresponding to the third-to-last tempering component 322.

[0036] This process continues until the glass 6 has completely passed through the tempering component 322 inside the tempering furnace 32, thus completing the ion exchange process.

[0037] Preferably, the tempered glass component 322 is provided with at least 7 sets.

[0038] This helps ensure the effectiveness of ion exchange.

[0039] Furthermore, the tempered component 322 also includes a protective plate 3223, which is located below the conveying roller 3221.

[0040] In a preferred embodiment of this technical solution, the tempering assembly 322 further includes a protective plate 3223 disposed below the conveying roller 3221. On the one hand, the protective plate 3223 can effectively prevent glass fragments located on the upper layer from falling onto the glass 6 located on the lower layer, thereby ensuring the tempering quality of the glass; on the other hand, it can also prevent molten alkali metal salts from falling onto the glass 6 located on the lower layer, which would result in uneven alkali metal salt thickness in the glass 6 within the same tempering furnace 32, causing a decrease in production consistency.

[0041] Preferably, the surface material of the protective plate 3223 is a heat-radiating material.

[0042] Thus, the protective plate 3223 can perform secondary radiative heating on the glass 6, thereby increasing temperature uniformity and better ensuring production stability. It should be noted that the heat radiation material in this solution can be metal, ceramic, graphite, etc., and is not limited thereto.

[0043] To further explain, the protective plate 3223 has a bent cross-sectional shape.

[0044] The bending structure design can effectively reduce the thermal deformation of the protective plate 3223 under high temperature conditions and improve the service life of the protective plate 3223.

[0045] Furthermore, the tempered glass assembly 322 also includes a plurality of temperature sensors 3224, which are horizontally spaced between the conveying roller 3221 and the infrared heating tube 3222. This improves the controllability of the ion exchange process.

[0046] Preferably, the temperature sensor 3224 is a thermocouple.

[0047] To further explain, the temperature sensors 3224 of the two adjacent tempering components 322 are staggered. This staggered arrangement allows for comprehensive monitoring of the temperature inside the tempering furnace 32, which is more conducive to improving the controllability of the ion exchange process.

[0048] Furthermore, the tempering furnace 32 also includes insulation cotton 323, which is disposed on the inner wall of the furnace body 321. This prevents rapid heat loss and saves energy.

[0049] Preferably, the tempering furnace 32 further includes a plurality of auxiliary heating tubes 324, which are installed horizontally at intervals below the protective plate 3223 of the bottom tempering component 322.

[0050] Adding an auxiliary heating tube 324 below the bottom tempered component 322 is more conducive to improving the ion exchange effect of glass 6 during the transport process of the bottom tempered component 322.

[0051] To further explain, the bond-breaking device 1 includes a first plasma processor 11, a bond-breaking and flipping machine 12, and a second plasma processor 13 connected end to end in sequence; Both the first plasma processor 11 and the second plasma processor 13 are used to perform plasma treatment on the surface of the glass 6 to be tempered; The key-breaking flipping machine 12 is used to flip the tempered glass 6.

[0052] The first plasma processor 11 and the second plasma processor 13 can use low-temperature plasma (such as oxygen plasma, argon plasma, air plasma) to bombard the glass surface, break the silicon-oxygen network structure on the glass surface, and generate active groups such as hydroxyl groups, thereby improving the surface energy and reactivity; when alkali metal salts are subsequently attached to the surface of the glass 6 to be tempered, it is more conducive to improving the uniformity of attachment.

[0053] It should be noted that the first plasma processor 11, the bond breaking and flipping machine 12, and the second plasma processor 13 in this solution are common devices in the field, and their specific structures will not be described in detail here.

[0054] To further explain, the attachment device 2 includes a first spraying mechanism 21, a drying mechanism 22, a spraying turning machine 23, and a second spraying mechanism 24 connected in sequence from end to end; Both the first spraying mechanism 21 and the second spraying mechanism 24 are used to spray the aqueous solution of the alkali metal salt onto the surface of the glass 6 to be tempered; The drying mechanism 22 is used to dry the surface of the glass 6 to be tempered; The spraying and flipping machine 23 is used to flip the glass 6 to be tempered.

[0055] Thus, spraying alkali metal salts in solution onto the surface of glass 6 can also effectively improve the uniformity of alkali metal salt adhesion.

[0056] It should be noted that the first spraying mechanism 21, the drying mechanism 22, the spraying and turning machine 23, and the second spraying mechanism 24 in this solution are common equipment in the field, and their specific structures will not be described in detail here.

[0057] To further clarify, the cooling device 4 is an air-cooled mechanism, and the cleaning device 5 is an ultrasonic cleaner. It should be noted that the air-cooled mechanism and ultrasonic cleaner in this solution are common devices in the field, and their specific structures will not be described in detail here.
