Description

TECHNICAL FIELD

[0001] The application relates to the technical field of mobile phone part processing, and particularly relates to a chemical toughening production line for a smart phone glass cover plate. BACKGROUND

[0002] The chemical toughening production line for a smart phone glass cover plate is core equipment for realizing high strength and high scratch resistance of the smart phone glass cover plate. The production line of the prior art usually comprises a series of sequentially connected equipment units, and the working process is as follows: first, the glass cover plate after CNC fine carving and polishing is sent into a multi-tank ultrasonic cleaning machine by a feeding machine, and surface contaminants are removed by using cleaning agents and ultrapure water; then, the clean glass enters a drying oven, and water is completely removed by high-efficiency hot air; after that, the dry glass is sent into an ion exchange furnace by an automatic conveying system to perform chemical strengthening; the glass after completing ion exchange has a very high temperature, needs to be slowly cooled by a cooling conveyor belt, and then enters a post-cleaning machine to remove salt deposits attached to the surface; finally, the glass is dried by a powerful air dryer, and quality detection is performed by an online stress meter and a surface flaw detection machine, and the qualified products can be discharged and packaged.

[0003] The ion exchange furnace is the core of the above production line, and the performance of the ion exchange furnace directly determines the quality of the toughened glass. The ion exchange furnace of the prior art mainly comprises a furnace body, a molten salt tank, a heating system, a temperature control system and a conveying system; the working principle is that a large amount of solid potassium nitrate is placed in the molten salt tank made of corrosion-resistant alloy, the solid potassium nitrate is heated to above the melting point by the electric heater wrapped outside the tank, and a constant-temperature molten state of ℃ to ℃ is formed; the glass workpiece is immersed in the molten salt through the ceramic track and is kept for several hours, and in this process, the sodium ions in the glass network structure are exchanged with the larger radius potassium ions in the molten salt, so that a compressive stress layer is formed on the surface layer of the glass.

[0004] In the chemical toughening process, the molten state of potassium nitrate is the medium for ion exchange, and the state stability is crucial. However, when the molten salt mixture is used for toughening in the prior art, as the production process continues, the sodium ions separated from the glass will continuously melt into the molten salt, especially around the glass workpiece, which will cause the composition of the molten salt to deteriorate, the concentration of potassium ions to decrease, and the ion exchange efficiency to decrease, which is manifested as the prolongation of the required process time and the deterioration of the toughening effect. Therefore, the chemical toughening production line for a smart phone glass cover plate is proposed. SUMMARY

Sealing plate is additionally arranged at the bottom of the unit ion exchange tank, and the sealing plate is provided with a liquid outlet passage;The flow guide cavities, the liquid outlets, the unit ion exchange tank and the liquid outlet passage constitute a molten salt mixture flow channel for providing a stable ion exchange environment for the intelligent mobile phone glass cover plate.

[0008] The liquid outlet passage includes a main liquid outlet passage and multiple side liquid outlet passages, and multiple liquid outlet passages are arranged on both sides of the main liquid outlet passage and arrayed along both sides of the main liquid outlet passage;The side liquid outlet passage communicates with the main liquid outlet passage.

[0009] The ion exchange tank further comprises an ion exchange tank seat, a surrounding baffle is arranged on the ion exchange tank seat, the surrounding baffle surrounds an upper part of the ion exchange tank seat to form a placing cavity for the grid ion exchange tank; a plurality of unit liquid outlet holes are arranged on the ion exchange tank seat, the plurality of unit liquid outlet holes correspond to the plurality of unit ion exchange tanks in a one-to-one manner, the unit liquid outlet hole is used for discharging the molten salt mixture in the unit ion exchange tank, the unit liquid outlet hole is communicated with the liquid outlet channel, and the unit liquid outlet hole is communicated with the mobilization base.

[0011] The mobilization base further comprises a discharge tank, the discharge tank is additionally arranged on the side wall of the standby storage tank, and the discharge tank is communicated with the plurality of unit mobilization tanks.

[0012] A cavity is arranged in the unit mobilization tank, a liquid pumping inner tube and a liquid guide pipe are arranged in the cavity, and a partition plate is arranged between the liquid pumping inner tube and the liquid guide pipe; a liquid inlet pipe and a liquid pumping pipe are arranged outside the unit mobilization tank, the liquid inlet pipe is communicated with the liquid guide pipe, and the liquid pumping pipe is communicated with the liquid pumping inner tube.

[0013] A heating grid frame is arranged on each side of the partition plate, the heating grid frame is composed of a plurality of heating plates, and the plurality of heating plates are arranged in a cross array; a heating guide wire is arranged on the heating plate, and the heating guide wire is used for heating the molten salt mixture; a discharge groove is arranged on the liquid pumping inner tube, and a feeding groove is arranged on the liquid guide pipe. After the molten salt mixture after ion exchange flows into the unit mobilization tank, the molten salt mixture enters the cavity through the discharge groove, and then is heated and temperature-controlled by the heating grid frames on both sides of the partition plate, so that the heating grid frame can ensure the temperature stability of the molten salt mixture on the basis of stirring and mixing the molten salt mixture, so that the molten salt mixture circulating at a stable temperature can continuously push the smart phone glass cover plate in a stable temperature environment, so as to avoid the insufficient flowability of the molten salt due to the uneven temperature, which can easily cause the difference in local component concentration and the inconsistent tempering degree of different regions of the same glass.

[0014] The unit mobilization box is internally provided with a detection assembly for monitoring the state of the molten salt mixture, the detection assembly comprising an electric conductivity sensor, a viscosity sensor and a density sensor, the electric conductivity sensor inferring the concentration change of sodium ions and potassium ions in the molten salt mixture by monitoring the change of electric conductivity, and the viscosity sensor and the density sensor inferring the component change of sodium ions and potassium ions in the molten salt mixture by measuring the change of the physical properties of density and viscosity. After the electric conductivity sensor, the viscosity sensor and the density sensor monitor the quality of the molten salt mixture, the performance of the molten salt mixture circulating in the unit mobilization box is maintained stable by the new molten salt mixture in the standby storage tank, which is beneficial to the high quality and intelligent phone glass cover chemical toughening of the molten salt mixture.

[0015] Compared with the prior art, the intelligent phone glass cover chemical toughening production line has the following advantages: 1. In the intelligent phone glass cover chemical toughening production line composed of a multi-tank ultrasonic cleaner, a drying furnace, an ion exchange furnace, a cleaning machine and a air dryer assembled in the transfer box and the guide rail and the toughening production equipment box, after the intelligent phone glass covers are transported to the ion exchange assembly, the covers and the ion exchange tanks are opened, and multiple intelligent phone glass covers are independently placed in multiple unit ion exchange tanks, and the chemical toughening treatment is independently carried out through the multiple unit ion exchange tanks, so that the molten salt mixture unit is independently toughened to treat the intelligent phone glass cover, which is beneficial to precise unit monitoring and regulation of the state of the molten salt mixture, so as to ensure the ion exchange efficiency and avoid the prolongation of the required process time. 2. After the intelligent phone glass cover is placed in the unit ion exchange tank, the molten salt mixture is uniformly and comprehensively pushed to the intelligent phone glass cover through multiple liquid outlets, so that the intelligent phone glass cover and the surrounding molten salt mixture are uniformly and comprehensively ion exchanged, and the degree of toughening of the intelligent phone glass cover is inconsistent. The flow guide cavity, the liquid outlet, the unit ion exchange tank and the liquid outlet channel constitute a molten salt mixture flow channel, which provides a stable ion exchange environment for the intelligent phone glass cover, avoids the non-flowing of the molten salt mixture, and the sodium ions separated out of the glass will continuously melt into the molten salt, especially around the glass workpiece, the local component concentration difference will cause the deterioration of the molten salt composition, the potassium ion concentration will decrease, the ion exchange efficiency will decrease, and the required process time will be prolonged, and the toughening effect will be poor. 3. The molten salt mixture is dispersed and introduced into the flow guide cavity through the liquid guide pipe and the liquid inlet pipe on the multiple unit mobilization boxes, then enters the unit ion exchange tank through the liquid outlet, and finally enters the unit liquid outlet through the liquid outlet channel. After the molten fused salt mixture after ion exchange flows into the unit mobilization box, it enters the cavity through the discharge slot, and then the molten fused salt mixture is heated and temperature-controlled by the heating grid frame on both sides of the partition, so that the heating grid frame can ensure the temperature stability of the molten fused salt mixture on the basis of stirring and mixing the molten fused salt mixture, so that the circulating molten fused salt mixture can continuously push the smart phone glass cover plate in a stable temperature environment, so as to avoid the insufficient flow of the molten fused salt due to uneven temperature, which is easy to cause local component concentration difference and inconsistent tempering degree in different areas of the same glass; 4. In the circulating flow ion exchange of the molten fused salt mixture, the conductivity sensor infers the concentration change of sodium ions and potassium ions in the molten salt mixture by monitoring the change of conductivity, and the viscosity sensor and the density sensor infer the component change of sodium ions and potassium ions in the molten salt mixture by measuring the physical property change of density and viscosity, so as to complete real-time monitoring of the state of the molten salt mixture. When the conductivity sensor, the viscosity sensor and the density sensor monitor that the quality of the molten salt mixture decreases, the new molten fused salt mixture in the standby storage tank is used to maintain the performance stability of the molten fused salt mixture in the circulating flow ion exchange in the unit mobilization box, which is beneficial to the high quality of the molten fused salt and the chemical tempering of the smart phone glass cover plate. 5. The present application divides the traditional large ion exchange tank into multiple independent unit ion exchange tanks, each of which is used to process a piece of smart phone glass cover plate. The molten fused salt mixture does not remain static, but continuously flows under the drive of a pump through a closed flow channel composed of a flow guide cavity, a liquid outlet hole, a unit ion exchange tank and a liquid outlet channel. The flowing molten fused salt mixture first uniformly and comprehensively flushes the surface of the smart phone glass cover plate in the unit ion exchange tank, ensuring the consistency of the ion exchange environment. Subsequently, the "waste salt" carrying the sodium ions separated from the glass is transported back to the unit mobilization box. In the unit mobilization box, the molten fused salt mixture flows through the heating grid frame, which not only reheats the molten fused salt mixture to maintain precise temperature stability, but also has the functions of stirring and mixing, thereby eliminating local component and temperature differences and homogenizing the molten salt composition. In order to maintain the activity and efficiency of the molten salt, the present application integrates conductivity sensors, viscosity sensors and density sensors to real-time infer the concentration change of potassium ions and sodium ions in the molten salt. When the quality of the molten salt is monitored to decrease, new molten salt can be automatically supplemented from the standby storage tank to dynamically maintain the performance stability of the molten salt mixture in the entire circulating system, thereby greatly prolonging the service life of the main molten salt while ensuring the tempering effect. Furthermore, it can also be achieved that: The traditional groove body cannot completely avoid the micro differences in flow rate and temperature at different positions in the glass array even if there is flow; and each unit ion exchange groove is an independent micro reactor with completely consistent fluid dynamics environment; this means that not only the quality of each batch of glass is stable, but also each piece of glass is in absolutely the same exchange environment, thereby realizing the unprecedented extreme uniformity of each piece and between pieces; this is a revolutionary improvement for the quality control of high-end flagship machine screens; The molten salt is actively and rapidly pushed to the glass surface through the liquid outlet hole, and this dynamic flushing effect can instantly remove the boundary layer of sodium ion enrichment on the glass surface after the exchange reaction, so that fresh molten salt with high potassium ion concentration can always fully contact with the glass surface; this greatly accelerates the kinetics of ion exchange, and is expected to significantly shorten the process time required to achieve the same tempering effect, thereby directly improving the production efficiency; The dispersion and stirring function of the heating grid frame is combined with the continuous and on-demand trace replenishment mechanism of the new molten salt, which actually forms a continuous molten salt composition regulation system. Instead of simply replacing the molten salt when it is completely ineffective, it is like a “life support system” that continuously supplies blood to the circulation system, so that the composition is always maintained near the optimal reaction range. This can extend the effective service life of the molten salt by several times, greatly reducing the cost of single production and the amount of waste salt to be treated, and bringing significant economic and environmental benefits; Since each unit ion exchange groove is independent and has independent molten salt circulation and monitoring, the system can accurately locate the state of each reaction unit; if the tempering data of a piece of glass is abnormal, the sensor data of the corresponding unit groove can be traced back immediately to accurately locate and diagnose the production problem; further, through long-term big data analysis of the sensor data, the performance decay trend of the molten salt and the equipment maintenance node can be predicted, realizing the upgrade from “preventive maintenance” to “predictive maintenance”, and maximizing the utilization rate of the equipment.

The cover plate 41 is detachably installed above the ion exchange tank 42, and the moving base 43 is installed at the bottom of the ion exchange tank 42. It should be noted that the ion exchange furnace is internally provided with an ion exchange assembly 4, which includes a cover plate 41, an ion exchange tank 42 and a moving base 43. The cover plate 41 is detachably installed above the ion exchange tank 42, and the moving base 43 is installed at the bottom of the ion exchange tank 42. The ion exchange tank 42 includes a grid ion exchange tank 421, which includes a plurality of horizontal plates 426 and a plurality of vertical plates 427. The plurality of horizontal plates 426 and the plurality of vertical plates 427 are staggered and arrayed, and form a plurality of unit ion exchange tanks 425. The plurality of unit ion exchange tanks 425 are used to independently place a plurality of smart phone glass cover plates 429 for chemical toughening treatment. Therefore, in the chemical toughening production line for the smart phone glass cover plate 429 formed by the combination of the transport box 1 and the guide rail 2, and the interior of the toughening production equipment box 3, which are internally provided with a multi-slot ultrasonic cleaning machine, a drying furnace, an ion exchange furnace, a cleaning machine and a air drying machine, after the smart phone glass cover plate 429 is transported to the ion exchange assembly 4, the cover plate 41 and the ion exchange tank 42 are opened, and a plurality of smart phone glass cover plates 429 are independently placed in a plurality of unit ion exchange tanks 425 for independent chemical toughening treatment, so as to realize the independent toughening treatment of the smart phone glass cover plate 429 by the molten salt mixture unit, which is beneficial to the precise unit monitoring and control of the state of the molten salt mixture, so as to ensure the ion exchange efficiency and avoid the prolongation of the required process time on the basis of ensuring the toughening effect.

[0020] It should be further noted that the molten salt mixture used for the chemical tempering of the 429 glass cover of mobile phones is existing technology. Its detailed structure can be found in existing literature and journals, and it can also be purchased directly on the market, or components can be purchased on the market to assemble it, etc. It is not what this invention is meant to protect, and will not be described in detail here. Those skilled in the art can purchase it at will according to their own needs.

[0021] In another embodiment of the present invention, such as Figure 5 , Figure 8 and Figure 9 As shown: Multiple liquid outlet holes 428 are provided on multiple horizontal plates 426 and multiple vertical plates 427; multiple liquid outlet holes 428 are distributed inside each unit ion exchange tank 425, and the liquid outlet holes 428 are used to discharge the molten salt mixture into the unit ion exchange tank 425.

[0022] In another embodiment of the present invention, Figure 9 As shown: The interior of the multiple horizontal plates 426 and multiple vertical plates 427 is provided with a flow guiding cavity, and multiple liquid outlet holes 428 are located on both sides of the flow guiding cavity and are connected to the flow guiding cavity; the liquid outlet holes 428 are unidirectional liquid outlet holes; the flow guiding cavity is connected to the adjustment base 43; A sealing plate 430 is installed at the bottom of the unit ion exchange tank 425, and a liquid outlet channel 420 is opened on the sealing plate 430. The guide cavity, the liquid outlet hole 428, the unit ion exchange tank 425 and the liquid outlet channel 420 constitute a flow channel for a molten salt mixture, which is used to provide a stable ion exchange environment for the smartphone glass cover 429.

[0023] Therefore, after the smartphone glass cover 429 is placed in the unit ion exchange tank 425, the molten salt mixture is uniformly and comprehensively pushed onto the smartphone glass cover 429 through multiple outlet holes 428, realizing a uniform and comprehensive ion exchange ring between the smartphone glass cover 429 and the surrounding molten salt mixture, avoiding inconsistent tempering of the smartphone glass cover 429; and the flow guide cavity, outlet holes 428, unit ion exchange tank 425 and outlet channel 420 constitute a flow channel for the molten salt mixture, providing a stable ion exchange environment for the smartphone glass cover 429, preventing the molten salt mixture from not flowing, and preventing sodium ions precipitated in the glass from continuously incorporating into the molten salt, especially around the glass workpiece, where local component concentration differences will lead to deterioration of the molten salt composition, a decrease in potassium ion concentration, and a reduction in ion exchange efficiency, resulting in a longer required process time and a poorer tempering effect.

[0024] In another embodiment of the present invention, Figure 9As shown: the liquid outlet channel 420 includes a main liquid outlet channel and a plurality of side liquid outlet channels, a plurality of liquid outlet channels are distributed on both sides of the main liquid outlet channel and are arrayed along both sides of the main liquid outlet channel; the side liquid outlet channel communicates with the main liquid outlet channel.

[0025] As shown in the figure: Figures 5-7 As shown: the ion exchange tank 42 further includes an ion exchange tank seat 422, and a surrounding baffle 423 is arranged on the ion exchange tank seat 422, which surrounds an upper part of the ion exchange tank seat 422 to form a placing cavity, and the placing cavity is used for placing the grid ion exchange tank 421. The ion exchange tank seat 422 is provided with a plurality of unit liquid outlet holes 424, and the plurality of unit liquid outlet holes 424 are in one-to-one correspondence with a plurality of unit ion exchange tanks 425; the unit liquid outlet hole 424 is used for discharging the molten salt mixture in the unit ion exchange tank 425; the unit liquid outlet hole 424 communicates with the liquid outlet channel 420, and the unit liquid outlet hole 424 communicates with the mobilization base 43.

[0026] The flow path of the molten salt mixture is: the molten salt mixture is introduced into the flow guide cavity by the mobilization base 43, then enters the unit ion exchange tank 425 through the liquid outlet hole 428, and after ion exchange, enters the unit liquid outlet hole 424 through the liquid outlet channel 420, and finally flows back to the inside of the mobilization base 43.

[0027] Meanwhile, the flow power of the molten salt mixture can be a pump, which is a prior art, and the detailed structure can be known from existing literature journals, and can also be directly purchased on the market, or the parts can be purchased on the market to be composed, etc.; it is not the protection of the present application, and will not be described in detail here, and those skilled in the art can select and purchase as needed.

[0028] In another embodiment of the present application, as shown in Figure 10 and Figure 11 As shown: the mobilization base 43 includes a standby storage tank 431 and a plurality of unit mobilization tanks 433, and the plurality of unit mobilization tanks 433 are distributed in multiple rows and multiple columns on the standby storage tank 431; the plurality of unit mobilization tanks 433 are in communication with the standby storage tank 431; an electromagnetic valve is installed at the communication position of the unit mobilization tank 433 and the standby storage tank 431.

[0029] As shown in the figure: Figure 10 As shown: the mobilization base 43 further includes a discharge tank 432, which is installed on the side wall of the standby storage tank 431, and the discharge tank 432 is in communication with the plurality of unit mobilization tanks 433.

[0030] The mobilization base 43 disperses the molten molten salt mixture into the flow guide cavity through the multiple unit mobilization boxes 433, and then the molten salt mixture enters the unit ion exchange tank 425 through the liquid outlet hole 428, and then enters the unit liquid outlet hole 424 through the liquid outlet channel 420 after ion exchange, and finally flows back to the multiple unit mobilization boxes 433.

[0031] In another embodiment of the application, as shown in Figure 10 and Figure 11 The unit mobilization box 433 is internally provided with a cavity 4333, and the cavity 4333 is internally provided with a liquid pumping inner tube 4336 and a liquid guide tube 4337, and the liquid pumping inner tube 4336 and the liquid guide tube 4337 are connected by a partition plate; The liquid inlet pipe 4331 and the liquid pumping pipe 4332 are arranged outside the unit mobilization box 433, the liquid inlet pipe 4331 is communicated with the liquid guide tube 4337 (specifically, the liquid inlet pipe 4331 is communicated with the flow guide cavity), and the liquid pumping pipe 4332 is communicated with the liquid pumping pipe 4332 (specifically, the liquid pumping pipe 4332 is communicated with the unit liquid outlet hole 424).

[0032] As shown in Figure 11 The partition plate is provided with a heating grid 4334 on both sides of the cavity 4333, and the heating grid 4334 is composed of a plurality of heating plates which are arranged in a cross array; The heating plate is provided with a heating wire, and the heating wire is used for heating the molten molten salt mixture; The liquid pumping inner tube 4336 is provided with a discharge slot 4335, and the liquid guide tube 4337 is provided with an inlet slot.

[0033] Therefore, in the face of the temperature of the different regions in the prior art molten salt tank, it is difficult to achieve absolute uniformity, and the insufficient flowability of the molten salt easily leads to local composition concentration difference, which will cause the different regions of the same furnace even the same piece of glass to have different tempering degrees; The application can achieve: The mobilization base 43 disperses the molten molten salt mixture into the flow guide cavity through the multiple unit mobilization boxes 433, and then the molten salt mixture enters the unit ion exchange tank 425 through the liquid outlet hole 428, and then enters the unit liquid outlet hole 424 through the liquid outlet channel 420 after ion exchange, and finally flows back to the multiple unit mobilization boxes 433 through the liquid pumping pipe 4332 and the liquid pumping inner tube 4336; After the molten molten salt mixture after ion exchange flows into the unit mobilization box 433, it enters the cavity 4333 through the discharge slot 4335, and then the molten molten salt mixture is heated and temperature-controlled by the heating grid 4334 on both sides of the partition, so that the heating grid 4334 can ensure the temperature stability of the molten molten salt mixture on the basis of stirring and mixing the molten molten salt mixture, so that the circulating molten molten salt mixture can continuously push the smart phone glass cover plate 429 in a stable temperature environment, so as to avoid uneven temperature causing insufficient molten salt flowability, which can easily cause local component concentration difference and inconsistent tempering degree in different areas of the same glass.

[0034] In another embodiment of the present application, the unit mobilization box 433 is internally provided with a detection assembly for monitoring the state of the molten molten salt mixture, which includes an electrical conductivity sensor, a viscosity sensor and a density sensor. The electrical conductivity sensor can infer the concentration change of sodium ions and potassium ions in the molten salt mixture by monitoring the change of electrical conductivity. The viscosity sensor and the density sensor can infer the component change of sodium ions and potassium ions in the molten salt mixture by measuring the change of physical properties of density and viscosity.

[0035] It should be noted that: the electrical conductivity of molten salt is related to its total ion concentration and composition; as the concentration of sodium ions increases (the concentration of potassium ions decreases), the overall electrical conductivity of the molten salt changes, so the electrical conductivity sensor can infer the concentration change of sodium ions and potassium ions in the molten salt mixture by monitoring the change of electrical conductivity; the density and viscosity of molten potassium nitrate and sodium nitrate are different. As the concentration of sodium ions increases, the density and viscosity of the molten salt change systematically, so the viscosity sensor and the density sensor can infer the component change of sodium ions and potassium ions in the molten salt mixture by measuring the change of physical properties of density and viscosity.

[0036] Therefore, in the circulating flow ion exchange of the molten molten salt mixture, the electrical conductivity sensor can infer the concentration change of sodium ions and potassium ions in the molten salt mixture by monitoring the change of electrical conductivity, and the viscosity sensor and the density sensor can infer the component change of sodium ions and potassium ions in the molten salt mixture by measuring the change of physical properties of density and viscosity, so as to complete real-time monitoring of the state of the molten salt mixture. After the electrical conductivity sensor, the viscosity sensor and the density sensor monitor the quality of the molten salt mixture, the new molten molten salt mixture in the standby storage tank 431 can be used to maintain the performance stability of the circulating flow ion exchange molten molten salt mixture in the unit mobilization box 433, which is beneficial to the high-quality molten molten salt mixture and the chemical tempering of the smart phone glass cover plate 429.

[0037] In another embodiment of the present application, the conventional large ion exchange tank is divided into multiple independent unit ion exchange tanks 425, each of which is dedicated to processing a piece of smart phone glass cover plate 429. The molten salt mixture is not static but continuously flows under the drive of a pump through a closed flow channel composed of a flow guide cavity, a liquid outlet hole 428, a unit ion exchange tank 425, and a liquid outlet passage 420. The flowing molten salt mixture first uniformly and comprehensively flushes the surface of the smart phone glass cover plate 429 in the unit ion exchange tank 425, ensuring the consistency of the ion exchange environment. Subsequently, the "waste salt" carrying the sodium ions separated from the glass is transported back to the unit mobilization tank 433. In the unit mobilization tank 433, the molten salt mixture flows through a heating grid 4334. The heating grid 4334 not only reheats it to maintain precise temperature stability, but also has the functions of stirring and mixing, thereby eliminating local composition and temperature differences and homogenizing the molten salt composition. In order to maintain the activity and efficiency of the molten salt, the present application integrates conductivity sensors, viscosity sensors, and density sensors to real-time infer the concentration changes of potassium ions and sodium ions in the molten salt. When the quality of the molten salt is monitored to be degraded, new molten salt can be automatically supplemented from the standby storage tank 431 to dynamically maintain the performance stability of the molten salt mixture in the entire circulating system, thereby greatly extending the service life of the main molten salt while ensuring the tempering effect. Furthermore, it can also achieve: The traditional tank body cannot completely avoid the micro differences in flow rate and temperature at different positions in the glass array even if it has flow. Each unit ion exchange tank 425 is an independent micro-reactor with a completely consistent fluid dynamics environment. This means that not only is the quality of each batch of glass stable, but each piece of glass is in an absolutely identical exchange environment, thereby achieving unprecedented single-piece internal and piece-to-piece extreme uniformity. This is a revolutionary improvement in the quality control of high-end flagship machine screens. The molten salt is actively and rapidly pushed to the glass surface through the liquid outlet hole 428. This dynamic flushing effect can instantly remove the boundary layer of sodium ion enrichment on the glass surface after the exchange reaction, so that fresh molten salt with high potassium ion concentration can always be in full contact with the glass surface. This greatly accelerates the kinetics of ion exchange and is expected to significantly shorten the process time required to achieve the same tempering effect, thereby directly improving production efficiency. The dispersing and stirring function of the heating grid 4334 combined with the continuous and on-demand micro-supplement mechanism of new molten salt actually constitutes a continuous molten salt composition regulation system. Instead of simply replacing the molten salt when it is completely ineffective, it continuously supplies blood to the circulating system like a "life support system", so that the composition always maintains near the optimal reaction interval. This can extend the effective service life of the molten salt by several times, greatly reducing the cost of single production and the amount of waste salt to be treated, bringing significant economic and environmental benefits. Since each unit ion exchange tank 425 is independent and has independent molten salt circulation and monitoring, the system can accurately locate the state of each reaction unit; if the tempering data of a certain piece of glass is abnormal, it can be traced back to the sensor data of the corresponding unit tank immediately to accurately locate and diagnose the production problem; further, through long-term big data analysis of the sensor data, the performance decay trend of the molten salt and the equipment maintenance node can be predicted, realizing the upgrade from "preventive maintenance" to "predictive maintenance", and maximizing the utilization rate of the equipment.

[0038] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application.
