Description

Technical Field

[0001] The present invention relates to the technical field of glass thinning, and in particular to a reaction control system and method for a UTG glass thinning process. Background Art

[0002] Glass plates are commonly used materials in people's lives. During the processing of glass plates, they will be thinned to make them lighter and thinner. When the thinned glass plates are assembled into specific products, the production requirements of thinner products can be met. Existing glass plate thinning technologies include physical methods and chemical methods. The physical method usually uses a grinding device to grind and thin one side of the glass plate, which has the problems of low thinning precision and low production efficiency. The chemical method usually etches the glass plate with a chemical etching solution to achieve a thinning effect. The glass plate obtained by chemical etching has a better surface effect and higher thinning efficiency, and is more suitable for industrial production.

[0003] In order to manufacture thinner glass substrates, the current method used is the immersion thinning method. The immersion thinning method is to put the glass thinning liquid into the reaction tank of the glass thinning equipment, and then put the glass into the glass thinning liquid for a certain period of time to allow the glass thinning liquid to react with the glass to achieve glass thinning.

[0004] However, when the glass plate is placed in a liquid storage tank for etching, the liquid level pressure difference of the etching liquid may cause uneven etching of the glass plate, thereby reducing the quality of the prepared glass plate product and the glass plate thinning accuracy. Summary of the Invention

[0005] In order to solve the technical problems mentioned in the above background technology, a reaction control system and method for UTG glass thinning process are proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A reaction control system for a UTG glass thinning process includes a reaction execution system, a timing module for timing the reaction time, and a controller connected to the timing module and the reaction execution system. The controller predicts the UTG glass thinning thickness based on the reaction time recorded by the timing module and adjusts the system parameters of the reaction execution system through feedback. A PLC control system can be used. The PLC control system is communicatively connected with various pumps, motors, cylinders, and fans. The PLC control system controls the operation of actuators such as the drive shaft, motor, water pump, exhaust pipe, and guide rod cylinder to achieve automated control and improve efficiency.

[0008] The reaction execution system includes a reaction chamber, a constant temperature chemical tank and a constant temperature pure water tank, and a fast switching reflux component is connected between the reaction chamber, the constant temperature chemical tank and the constant temperature pure water tank;

[0009] The reaction chamber is provided with a plurality of transmission shafts, on which glass thinning modules are placed, and a rotating mechanism that drives the glass thinning modules to rotate 360 ​​degrees forward and reverse. The top of the reaction chamber is provided with a spray assembly and a driving device that drives the overall movement of the spray assembly. The top of the reaction chamber is connected to an exhaust pipe;

[0010] A water pump is installed on the top of the constant temperature chemical liquid tank and the constant temperature pure water tank. The output end of the water pump is connected to the spray component, and the spray component sprays chemical liquid or pure water onto the glass thinning module.

[0011] The entire machine is driven by multiple servo controls with adjustable speeds and multiple speed ranges. Based on the predicted changes in the concentration of the chemical solution, the system automatically changes the applied speed value to ensure that the relevant parameters of each set of glass thinning are within the specified range.

[0012] The constant temperature chemical tank and the constant temperature pure water tank have their own constant temperature function, which keeps the temperature of the etching solution and pure water at a constant value. On the one hand, it will not cause the etching solution to react too quickly due to the high temperature, resulting in the problem of excessive thickness deviation of the glass within the set time. On the other hand, the pure water quickly cools the surface of the glass to stop the reaction of the residual etching solution on the glass.

[0013] In the present invention, the reciprocating movement and rotation of the glass thinning module on the transmission shaft are conducive to driving the flow of the etching liquid, and the up and down and forward and backward movement of the spray assembly relative to the glass thinning module are conducive to the irregular spraying of the etching liquid on the glass plate, thereby making the etching liquid flow more evenly on the glass plate, thereby avoiding the problem of uneven etching of the glass plate, improving the thinning accuracy of the glass plate, and obtaining a high-quality finished thinned glass plate.

[0014] As a further description of the above technical solution:

[0015] The spray assembly includes a nozzle holder capable of translational and elevation movement within the reaction chamber. Multiple third connecting tubes are rotatably mounted on the nozzle holder, with multiple fan-shaped nozzles mounted at the bottom of the third connecting tubes. Multiple liquid supply tubes are fixedly mounted on the top of the reaction chamber, with the output ends of the liquid supply tubes connected to multiple first connecting tubes, and a second connecting tube connected between the first and third connecting tubes. The spray assembly is used to spray etching liquid and pure water onto the glass plate. The etching liquid thins the glass, while the pure water cleans the glass. The third connecting tube is rotatable, and the angle of the nozzle is adjustable, facilitating adjustment of the angle of the etching liquid fan of the nozzle, allowing the etching liquid to more easily enter between the glass sheets of the glass thinning module.

[0016] As a further description of the above technical solution:

[0017] The constant-temperature chemical tank contains an etching liquid chamber and a pure water chamber. An infusion pump connected to the two chambers is installed on the constant-temperature chemical tank. The liquid supply pipe includes an etching liquid pipe and a pure water pipe spaced apart. The two water pumps are connected to the etching liquid pipe and the pure water pipe, respectively, via pipes. First, pure water and etching liquid can be quickly switched. A pure water pipe is placed between each two etching liquid pipes. This allows the etching liquid to stop flowing while pure water is rinsed in the shortest possible time, leaving the glass surface free of etching liquid flow marks and crystallization points. Second, the power output of the infusion pump is frequency-controlled to adjust the pressure of the etching liquid fan curtain from the nozzle. As the glass in the device reacts longer, the glass becomes thinner accordingly. Based on the predicted amount of glass thinning, the system automatically reduces the pump's output power to reduce the pressure of the etching liquid fan curtain from the nozzle of the nozzle to the glass surface, thereby reducing damage to the glass.

[0018] As a further description of the above technical solution:

[0019] The drive device includes a lifting mechanism that drives the nozzle holder upward and downward. The lifting mechanism includes a horizontal frame with rollers rotatably mounted on both sides of the nozzle holder, which are in rolling contact with the horizontal frame. A first motor is fixedly mounted on the top of the reaction chamber. The output shaft of the first motor is drivingly connected to a screw, and the free end of the screw is screwed to the horizontal frame via a threaded connection. The nozzle holder is adjustable in height, allowing the height of the etching liquid fan from the nozzle to be adjusted from the glass thinning module, thereby adjusting the pressure and flow rate of the etching liquid curtain falling on the glass surface.

[0020] As a further description of the above technical solution:

[0021] The drive device includes a translation mechanism for driving the nozzle holder to translate. The translation mechanism includes a second motor. A crank is fixedly sleeved on the output shaft of the second motor. The free end of the crank is rotatably connected to a connecting rod. The free end of the connecting rod is rotatably connected to a second connecting plate. Guide rods are fixedly connected to both sides of the second connecting plate. A vertical plate is fixedly connected to one side of the nozzle holder. The vertical plate has slide grooves on both sides. The free end of the guide rod passes through a bearing guide sleeve mounted on the reaction chamber and is slidably connected to the slide groove. The end of the guide rod is fixedly sleeved on a limit ring. The translation mechanism drives the nozzle holder to move back and forth, causing the liquid to be sprayed onto the glass plate in an irregular manner, thereby thinning the glass plate.

[0022] As a further description of the above technical solution:

[0023] The crank and connecting rod are connected by a joint bearing. The crank has multiple adjustment holes for mounting the joint bearings, which are used to adjust the reciprocating stroke of the nozzle holder. Adjusting the mounting position of the joint bearings allows the nozzle holder to move forward and backward within a certain range, allowing the spray nozzles to overlap, effectively preventing uneven spraying of the spray onto the glass plate.

[0024] As a further description of the above technical solution:

[0025] The rapid-switch reflux assembly includes an inverted V-shaped reflux trough connecting the reaction chamber to the constant-temperature chemical solution tank and the constant-temperature pure water tank. A reflux box slides within the trough, mounted on a guide rod cylinder. The output ends of the two guide rod cylinders are connected to the constant-temperature chemical solution tank and the constant-temperature pure water tank, respectively. Precision cylinders are installed in the reflux system for both the etching solution and pure water, enabling rapid switching between pure water and etching solution, each returning to its own tank. This maximizes etching solution concentration to avoid affecting the system parameters set for subsequent glass thinning.

[0026] As a further description of the above technical solution:

[0027] The rotating mechanism includes a motor box, in which a rotating servo motor is installed. The glass thinning module includes a front plate and a rear plate. Multiple groups of glass fixing components are arranged between the front plate and the rear plate. Pads are inserted between adjacent glass fixing components. The front plate, the rear plate, the pads and the glass fixing components are fixedly connected by screws. The output shaft of the rotating servo motor is fixedly connected to the front plate through a first connecting plate.

[0028] As a further description of the above technical solution:

[0029] The glass fixing assembly includes a vacuum plate, a plurality of vacuum pipes are cross-arranged inside the vacuum plate, and a vacuum pipe plug is installed at the end of the vacuum pipe. A groove for accommodating the glass plate is provided on the vacuum plate, and a plurality of vacuum holes and measuring holes are provided in the groove. The vacuum holes are connected to the vacuum pipe, and a vacuum manual valve is installed on the vacuum pipe.

[0030] As a further description of the above technical solution:

[0031] A method for a reaction control system for a UTG glass thinning process, comprising the following steps:

[0032] S1, the drive shaft reciprocates to drive the glass thinning module to move back and forth. The controller predicts the concentration of the solution based on the reaction time recorded by the timing module and adjusts the speed of the drive shaft based on feedback.

[0033] S2. A water pump delivers etching liquid through an etching liquid pipe and sprays the etching liquid onto the glass plate through a nozzle. The translation mechanism drives the nozzle frame to move back and forth. The rotary servo motor drives the glass thinning module to rotate back and forth. The etching liquid is sprayed irregularly onto the glass plate to thin the glass plate. The etching liquid flows back into the constant temperature chemical tank through the reflux plate and the fast switching reflux component.

[0034] The controller predicts the glass thinning thickness based on the reaction time recorded by the timing module, and provides feedback to adjust the output power of the water pump, the height of the nozzle rack, the speed of the rotary servo motor, and the exhaust volume of the exhaust pipe;

[0035] S3. After the glass plate etching solution reacts, the water pump in step S2 is turned off and another water pump is turned on. At the same time, the reflux box is switched through the guide rod cylinder to connect the reaction chamber and the constant temperature pure water tank. Pure water is sprayed on the glass plate through the pure water pipe and the nozzle to clean the glass plate.

[0036] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0037] 1. In the present invention, the reciprocating movement and rotation of the glass thinning module on the transmission shaft are conducive to driving the flow of the etching liquid. The up and down and forward and backward movement of the spray assembly relative to the glass thinning module is conducive to the irregular spraying of the etching liquid on the glass plate, thereby making the etching liquid flow more evenly on the glass plate, thereby avoiding the problem of uneven etching of the glass plate, improving the thinning accuracy of the glass plate, and obtaining a high-quality finished thinned glass plate.

[0038] 2. In the present invention, the constant temperature chemical tank and the constant temperature pure water tank have their own constant temperature function, which keeps the temperature of the etching solution and the pure water at a constant value. On the one hand, the problem of excessive thickness deviation of the glass within the set time due to excessive reaction of the etching solution at too high a temperature will not occur. On the other hand, the pure water quickly cools the surface of the glass to stop the reaction of the residual etching solution on the glass.

[0039] 3. In the present invention, as the reaction time increases, it is predicted that the glass will become thinner and the acidity of the solution will become lower. The reaction execution system gradually reduces the speed of the drive shaft and the rotary servo motor, the output power of the water pump, and the exhaust volume of the exhaust pipe according to the development trend of the glass thickness, so that the current system parameters are adapted to the thinning of the glass of the current thickness, avoiding always using a certain specified parameter to thin the glass of different thicknesses before and after the same glass thinning process, resulting in damage to the thinner glass in the later stage, thereby reducing the glass breakage rate.

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0053] Example 1

[0054] See also Figure 1-10 The present invention provides a technical solution: a reaction control system for the UTG glass thinning process, comprising a reaction execution system, a timing module for measuring reaction time, and a controller connected to the timing module and the reaction execution system. The controller uses the reaction time recorded by the timing module to predict the UTG glass thinning thickness and provide feedback to adjust the system parameters of the reaction execution system. A PLC control system can be used. The PLC control system is communicatively connected to various pumps, motors, cylinders, and fans. The PLC control system controls the operation of actuators such as the drive shaft, motor, water pump, exhaust duct, and guide rod cylinder, achieving automated control and improving efficiency.

[0055] Assuming that the size of the glass to be thinned is 400×400mm, the glass thickness is 0.15mm, and the required glass thickness is 0.03-0.050mm, it is now thinned. During the thinning process, the system parameters of the reaction execution system adjustment are shown in Table 1 below:

[0056]

[0057] Table 1

[0058] According to Table 1, it can be concluded that as the reaction time increases, it is predicted that the glass will become thinner and the acidity of the solution will become lower. The reaction execution system gradually reduces the speed of the drive shaft 3 and the rotary servo motor 41, the output power of the water pump 12, and the exhaust volume of the exhaust pipe 11 according to the development trend of the glass thickness, so that the current system parameters are adapted to the thinning of the current thickness of the glass, avoiding always using a certain specified parameter to thin the glass of different thicknesses before and after the same glass thinning process, resulting in damage to the thinner glass in the later stage, and reducing the glass breakage rate.

[0059] Furthermore, after performing several thinning processes of the glass thinning module 5 , the concentration of the chemical solution in the constant temperature chemical solution tank 1001 needs to be tested and adjusted according to the reaction requirements.

[0060] Specifically, such as Figure 1 As shown, the reaction execution system includes a reaction chamber 1, a constant temperature chemical tank 1001 and a constant temperature pure water tank 1002, and a fast switching reflux component 9 is connected between the reaction chamber 1 and the constant temperature chemical tank 1001 and the constant temperature pure water tank 1002. Specifically, the fast switching reflux component 9 includes an inverted V-shaped reflux groove 901 connecting the reaction chamber 1 and the constant temperature chemical tank 1001 and the constant temperature pure water tank 1002. A reflux box 902 is slidably provided in the reflux groove 901, and a guide rod cylinder 903 is installed on the reflux box 902. The output ends of the two guide rod cylinders 903 are respectively connected to the constant temperature chemical tank 1001 and the constant temperature pure water tank 1002. The reflux box 902 is driven by the cylinder 903 to move and connect to the reflux port on the reaction chamber 1, so that the etching solution or pure water flows back into the constant temperature chemical tank 1001 or the constant temperature pure water tank 1002 through the reflux groove 901 along the specified reflux direction.

[0061] Specifically, such as Figure 1As shown, the reaction chamber 1 is provided with several transmission shafts 3, on which are placed glass thinning modules 5 and a rotating mechanism 4 that drives the glass thinning modules 5 to rotate forward and reverse 360 ​​degrees. The top of the reaction chamber 1 is provided with a spray assembly 7 and a driving device that drives the spray assembly 7 to move as a whole. The top of the reaction chamber 1 is connected to an exhaust pipe 11, wherein the transmission shaft 3 is set with different rotation speeds for driving the glass thinning module 5 to move back and forth. The spray assembly 7 is used to spray etching liquid or pure water on the glass plate from above. The glass thinning module 5 and the nozzle 77 move relative to each other, so that the etching liquid is sprayed irregularly on the glass plate to avoid uneven thinning caused by too long or too short reaction time at a certain part of the glass sheet. The exhaust volume of the exhaust pipe 11 is adjustable to discharge the acid mist in the reaction chamber 1 to avoid the acid mist condensing on the top of the reaction chamber 1 to form water droplets, which fall on the glass plate and cause local excessive reaction of the glass.

[0062] Specifically, such as Figure 8 As shown, the rotating mechanism 4 includes a transparent motor box 42, in which a rotating servo motor 41 is installed. The glass thinning module 5 includes a front plate 51 and a rear plate 54. A plurality of glass fixing assemblies 53 are arranged between the front plate 51 and the rear plate 54. A pad 52 is inserted between adjacent glass fixing assemblies 53. A positioning rod is fixedly connected to the pad 52. A positioning hole 5313 for accommodating the positioning rod is provided on the vacuum plate 531. The front plate 51, the rear plate 54, the glass fixing assemblies 53 and the pad 52 are fixedly connected by screws. The screws pass through the threaded holes 5314 on the front plate 51, the rear plate 54, the pad 52 and the vacuum plate 531, and are locked by nuts. During the glass thinning process, the glass thinning module 5 is driven to rotate back and forth by the rotating servo motor 41, so that the glass can be sprayed with liquid from multiple angles. This is suitable for thinning larger glasses and avoids the situation where the glass is sprayed with liquid from a single direction, causing uneven thinning.

[0063] Specifically, such as Figure 9 and Figure 10As shown, the glass fixing assembly 53 includes a vacuum plate 531, and a plurality of vacuum pipes 534 are cross-arranged inside the vacuum plate 531, and a vacuum pipe plug 533 is installed at the end of the vacuum pipe 534. A groove 5311 for accommodating a glass plate is provided on the vacuum plate 531, and a plurality of vacuum holes 5315 and a measuring hole 5312 are provided in the groove 5311. The vacuum holes 5315 are connected to the vacuum pipe 534, and a vacuum manual valve 532 is installed on the vacuum pipe 534. The glass plate is placed in the groove 5311, and a vacuum pump is connected to the vacuum manual valve 532. After the vacuum pump works and adsorbs the glass plate in the groove 5311, the vacuum manual valve 532 is closed. The plurality of vacuum plates 531 with glass plates fixed thereon are combined with the gasket 52, the front plate 51, and the rear plate 54 to obtain a glass thinning module 5, wherein a protective film is covered on the back of the glass plate, and the glass thickness is measured through the measuring hole 5312.

[0064] Specifically, such as Figure 2 and Figure 3 As shown, the spray assembly 7 includes a nozzle rack 77 that can perform translational and lifting movements in the reaction chamber 1. A plurality of third connecting pipes 75 are rotatably mounted on the nozzle rack 77. A plurality of fan-shaped nozzles 76 are mounted at the bottom of the third connecting pipe 75. A plurality of liquid supply pipes are fixedly provided on the top of the reaction chamber 1. The output ends of the liquid supply pipes are connected to a plurality of first connecting pipes 73. A second connecting pipe 74 is connected between the first connecting pipe 73 and the third connecting pipe 75. The second connecting pipe 74 is a hose. The etching liquid or pure water is delivered to the nozzle 76 through the first connecting pipe 73, the second connecting pipe 74 and the third connecting pipe 75, and is sprayed out through the fan-shaped nozzle 76. The third connecting pipe 75 can be rotated to adjust the angle of the nozzle 76, thereby adjusting the angle of the liquid curtain sprayed by the fan-shaped nozzle 76.

[0065] Specifically, such as Figure 2 and Figure 4 As shown, the driving device includes a lifting mechanism 6 for driving the nozzle frame 77 to rise and fall. The lifting mechanism 6 includes a horizontal frame 63. Rollers 79 that are rotatably installed on both sides of the nozzle frame 77 and are in rolling contact with the horizontal frame 63. A first motor 61 is fixedly installed on the top of the reaction chamber 1. The output shaft of the first motor 61 is connected to the screw rod 62. The free end of the screw rod 62 is screwed to the horizontal frame 63 through a threaded connection. The screw rod 62 is driven to rotate by the second motor 61. According to the principle of thread transmission, the horizontal frame 63 is driven to rise and fall, and the horizontal frame 63 drives the nozzle frame 77 to rise and fall, adjusting the distance between the sector of the etching liquid and the glass thinning module, so as to achieve the adjustment of the pressure and flow rate of the sector liquid curtain falling on the glass surface.

[0066] Specifically, such as Figure 2 and Figure 5As shown, the driving device includes a translation mechanism 8 for driving the nozzle frame 77 to translate. The translation mechanism 8 includes a second motor 81. A crank 82 is fixedly sleeved on the output shaft of the second motor 81. The free end of the crank 82 is rotatably connected to a connecting rod 83. The free end of the connecting rod 83 is rotatably connected to a second connecting plate 84. Guide rods 85 are fixedly connected on both sides of the second connecting plate 84. A vertical plate 78 is fixedly connected to one side of the nozzle frame 77, and a slide groove 781 is provided on both sides of the vertical plate 78. The free end of the guide rod 85 passes through a bearing guide sleeve 86 installed on the reaction chamber 1 and is slidably connected to the slide groove 781. The end of the guide rod 85 is fixedly sleeved with a limit ring. The crank 82 is driven to rotate by the third motor 81. The crank 82 drives the connecting rod 83 to swing back and forth. The connecting rod 83 drives the second connecting plate 84 and the guide rod 85 to reciprocate. The guide rod 85 drives the nozzle frame 77 to reciprocate on the horizontal frame 63. The nozzle 76 moves synchronously to achieve irregular spraying of the etching liquid.

[0067] Among them, such as Figure 6 As shown, the crank 82 and the connecting rod 83 are connected by a joint bearing 88, and the crank 82 has multiple adjustment holes 821 for installing the joint bearing 88. The reciprocating movement amplitude of the nozzle holder 77 is adjusted to make the medicine sprayed from the nozzle overlap, effectively avoiding the phenomenon of uneven overlap of the medicine sprayed onto the glass plate.

[0068] Specifically, such as Figure 1 and Figure 7 As shown, a water pump 12 is installed on the top of the constant temperature chemical tank 1001 and the constant temperature pure water tank 1002. The liquid supply pipe includes an etching liquid pipe 71 and a pure water pipe 72 arranged at intervals. The two water pumps 12 are connected to the etching liquid pipe 71 and the pure water pipe 72 respectively through pipes. The constant temperature chemical tank 1001 and the constant temperature pure water tank 1002 have their own constant temperature functions, which keep the temperature of the etching liquid at 22-25 degrees. The etching liquid will not react too quickly due to excessive temperature, resulting in excessive thickness deviation of the glass within the set time. The temperature of the constant temperature pure water tank 1002 is 15-18 degrees, which quickly cools the surface of the glass to stop the reaction of the residual etching liquid on the glass.

[0070] S1, the transmission shaft 3 reciprocates to drive the glass thinning module 5 to move back and forth, and the controller predicts the concentration of the liquid medicine according to the reaction time recorded by the timing module, and adjusts the speed of the transmission shaft 3 based on feedback;

[0071] S2, the water pump 12 delivers the etching liquid through the etching liquid pipe 71 and sprays the etching liquid onto the glass plate through the nozzle 76, the translation mechanism 8 drives the nozzle frame 77 to translate back and forth, and the rotary servo motor 41 drives the glass thinning module 5 to rotate back and forth. The etching liquid is sprayed irregularly on the glass plate to thin the glass plate, and the etching liquid flows back into the constant temperature chemical tank 1001 through the reflux plate 2 and the fast switching reflux component 9;

[0072] The controller predicts the glass thinning thickness based on the reaction time recorded by the timing module, and adjusts the output power of the water pump 12, the height of the nozzle rack 77, the speed of the rotary servo motor 41, and the exhaust volume of the exhaust pipe 11 based on feedback;

[0073] S3. After the glass plate etching liquid reacts, the water pump 12 in step S2 is turned off and the other water pump 12 is turned on. At the same time, the reflux box 902 is switched through the guide rod cylinder 903 to connect the reaction chamber 1 with the constant temperature pure water tank 1002. Pure water is sprayed on the glass plate through the pure water pipe 72 and the nozzle 76 to clean the glass plate.
