Description

Technical Field

[0001] This application relates to the field of glass substrate manufacturing technology, and in particular to a method and system for designing the motor power of a TFT platinum channel stirrer. Background Technology

[0002] In the production process of TFT-LCD, OLED, and other liquid crystal glass substrates, the melted glass raw materials need to be stirred and homogenized in a platinum channel to improve the chemical and thermal uniformity of the molten glass. A stirring rod is typically installed in the platinum channel. Driven by a motor, the stirring rod rotates, causing the high-temperature molten glass to flow, thereby achieving mixing and homogenization. Because the molten glass in the platinum channel is at a high temperature and has high viscosity, the stirring rod experiences significant viscous resistance during operation. Therefore, the appropriate design of the motor power directly affects whether the stirring rod can meet the predetermined stirring conditions and the operational reliability of the stirring system.

[0003] The design of motor power in existing mixing equipment typically draws on methods used in the chemical industry to calculate mixing power. This involves calculating the mixing power based on parameters such as fluid density, mixing speed, stirring rod diameter, and power rating, and then determining the motor power based on parameters such as transmission efficiency. For example, traditional mixing power calculations usually employ... Relationship, This indicates the stirring power required when the stirring rod is used to stir the molten glass. This represents the power index, used to characterize the influence of the stir bar structure and flow state on the stirring power. This indicates the density of molten glass. This indicates the rotational speed of the stirring rod. Indicates the diameter of the stirring rod. Power rating. It usually needs to be determined based on the stirring Reynolds number. It is determined by the corresponding power metric curve.

[0004] However, in actual stirring processes, geometric parameters such as the number of blades, blade shape, angle between the blades and the horizontal plane, number of blade layers, and blade working area of ​​the stirring rod all affect the viscous resistance experienced by the molten glass and the driving power required by the stirring rod. Therefore, under different stirring rod structures or different platinum channel sizes, it is often necessary to rely on experience to adjust the parameters and repeatedly determine the motor specifications through design, trial production, and testing.

[0005] Therefore, the existing motor power design for TFT platinum channel stirrers has the problem of not being able to accurately characterize the relationship between the stirring load of high-viscosity glass melt and the geometric parameters of the stirrer. This leads to a high dependence on experience and experimental iterations in motor power design, which in turn results in motor power being too high or too low, affecting the stability of the equipment during actual operation. Summary of the Invention

[0006] To address the problem that existing stirring rod motor power design methods lack accuracy, leading to insufficient stability during actual equipment operation, this application provides a motor power design method and system for a TFT platinum channel stirring rod.

[0007] In a first aspect, this application provides a method for designing the motor power of a TFT platinum channel stirrer, employing the following technical solution: A method for designing the motor power of a TFT platinum channel stirring rod includes: obtaining the design boundary parameters and preliminary design parameters of the stirring rod; the preliminary design parameters include the blade stirring diameter, the number of blades per layer, the blade height, the number of blade layers along the stirring rod axis, the sum of the shear areas of all blades, and the angle between the blades and the horizontal plane. Based on the preliminary design parameters, a three-dimensional geometric space model is generated and comprehensive geometric constants are determined; the comprehensive geometric constants are positively correlated with the sum of shear areas, the number of blades per layer, and the number of blade layers, and negatively correlated with the angle between the blades and the horizontal plane; The operating power of the stirring rod is calculated based on the comprehensive geometric constant and the design boundary parameters; the product of the operating power and the set safety margin coefficient is divided by the transmission system efficiency to obtain the design power of the motor; the operating power is proportional to the comprehensive geometric constant.

[0008] By uniformly converting actual geometric factors such as the number of blades, blade height, number of blade layers, shear area, and blade tilt angle into a comprehensive geometric constant, the operating power can be adjusted accordingly to changes in the specific stirring rod structure. This allows for a more accurate characterization of the actual load exerted on the stirring rod by the high-viscosity TFT glass melt, helping to reduce the design process that relies on repeated trial and test based on experience. At the same time, by converting the stirring rod's operating power into the motor's design power through a safety margin factor and transmission system efficiency, the system can take into account load fluctuations, transmission losses, and starting risks, reducing the risk of insufficient equipment stability due to excessively high or low motor power.

[0009] Optionally, design boundary parameters include: the viscosity of the TFT glass melt at the operating temperature and the rotational speed of the stir bar under the process target.

[0010] By using the viscosity of the TFT glass melt at the actual operating temperature and the target rotation speed of the process as design boundary parameters, the power calculation can reflect the load differences under different thermal regimes and stirring processes, rather than using room temperature properties or fixed empirical parameters.

[0011] Optionally, the formula for calculating the operating power of the stirring rod based on the comprehensive geometric constants and the design boundary parameters is as follows: ; In the formula, The operating power of the stirring rod is expressed in watts. The density of molten glass; The rotational speed of the stirring rod; The diameter of the impeller is in meters. Viscosity; It is a comprehensive geometric constant.

[0012] The influence of comprehensive geometric constants, viscosity, target stirring speed and impeller diameter on operating power is clearly defined, so that the power results can be quantitatively updated as the viscous resistance of the glass melt and the stirring intensity change. This can reduce the power deviation caused by directly extrapolating conventional chemical turbulence experience to TFT glass melt, and provide a clear basis for speed adjustment and impeller size optimization.

[0013] Optionally, the formula for calculating the comprehensive geometric constant is: ;in, These are the composite geometric constants; The set reference geometric base; The blade cross-sectional area coefficient is the ratio of the sum of the shear areas of all blades to the horizontal cross-sectional area of ​​the platinum mixing tank. This is the coefficient for the number of blades in a single layer, which is positively correlated with the number of blades in a single layer. is the blade tilt angle coefficient, and is the cosine function value of the blade tilt angle; This is the blade layer number coefficient, which is positively correlated with the blade layer number.

[0014] The blade shear area, number of blades per layer, blade inclination angle, and number of blade layers are converted into corresponding coefficients and combined to form a comprehensive geometric constant. This allows the influence of different stirring rod structures on the load to be calculated separately, overcoming the problem that existing power parameters cannot directly explain the differences in specific blade structures.

[0015] Optionally, the formula for calculating the number of blades per layer is: In the formula, This is the coefficient for the number of blades in a single layer; This refers to the number of blades in a single layer. This is a reduction value related to the circumferential density of the blades.

[0016] It is understandable that the blades influence each other during the actual stirring process. Therefore, the circumferential interference caused by the increase in the number of blades is reduced, and the cosine function of the tilt angle is used to characterize the effective upstream projection of the blades. This makes the calculation results no longer simply linearly sum the number of blades and the area of ​​action, thereby reducing the risk of overestimating the stirring load when the blades are arranged densely. As a result, it can more closely reflect the actual shearing action of the blades in the molten glass.

[0017] Optionally, the formula for calculating the blade layer number factor is: In the formula, Indicates the blade layer number coefficient; Indicates the number of blade layers; This is a reduction value related to the axial density of the blades.

[0018] By introducing a reduction value related to the axial density, the decrease in the marginal effect caused by flow field overlap and mutual interference between multiple layers of blades can be reflected in the power calculation, avoiding the simple proportional superposition of the loads of each layer of blades.

[0019] Optionally, the value of the safety margin factor is determined based on the operating conditions of the platinum channel: When the operating condition is a stable continuous stirring condition, the safety margin coefficient takes a value within the set lower limit range. When the operating condition is a cold start condition that includes a long period of agitation followed by a restart, the safety margin coefficient takes a value within the set upper limit range.

[0020] The safety margin is determined by differentiating between two operating conditions: continuous operation and cold start after agitation is stopped. This reduces the problem of over-selection for stable operating conditions or insufficient reserve for cold start operating conditions when using fixed margin coefficients in existing technologies, thus making the equipment more targeted to different operating conditions.

[0021] Optionally, after obtaining the preliminary design parameters of the stirring rod, the method further includes: performing a geometric validity check on the preliminary design parameters. Verify whether the ratio of the impeller diameter to the inner diameter of the platinum mixing tank falls within the set diameter ratio range; Verify whether the angle between the blade and the horizontal plane falls within the set angle range.

[0022] By verifying the geometric validity of the blade size ratio and blade tilt angle, design schemes with insufficient mixing capacity, excessively small barrel wall clearance, or blade angles exceeding the applicable range can be eliminated in advance.

[0023] Optionally, after obtaining the design boundary parameters of the stirring rod, the process may also include: Perform fluid validity verification on the design boundary parameters: Verify whether the viscosity is within the preset range; Verify that the stirring speed is positive and does not exceed the set process upper limit.

[0024] Secondly, this application provides a motor power determination system for a TFT platinum channel stirring rod, which adopts the following technical solution: A system for determining the motor power of a TFT platinum channel stirrer includes a processor and a memory. The memory stores computer program instructions, which, when executed by the processor, implement the motor power design method for a TFT platinum channel stirrer as described above.

[0025] The above-mentioned method for designing the motor power of a TFT platinum channel stirrer is used to generate a computer program, which is then stored in a memory for loading and execution by a processor. This allows for the creation of a system based on the memory and processor, making it convenient to use.

[0026] This application has the following technical effects: By comprehensively quantifying geometric factors such as the number of blades, height, number of layers, shear area, tilt angle, and blade diameter, and combining them with viscosity and stirring rod speed to calculate operating power, we can reduce experience-based trial production and repeated testing, lower the risk of under- or over-selection of motors, and improve the stability of TFT platinum channel stirring equipment during actual operation.

[0027] Figure 1 This is a schematic diagram of a method for designing the motor power of a TFT platinum channel stirrer according to an embodiment of this application. Detailed Implementation

[0028] This application discloses a method for designing the motor power of a TFT platinum channel stirrer.

[0029] Reference Figure 1 A method for designing the motor power of a TFT platinum channel stirring rod includes steps S1-S3.

[0030] S1: Obtain the design boundary parameters and preliminary design parameters of the stirring rod.

[0031] Specifically, the design boundary parameters are entered by the operator through a human-machine interface. The design boundary parameters include: melt property parameters, process target parameters, and equipment constraint parameters.

[0032] The melt properties include: operating temperature, viscosity, and density at the operating temperature. The operating temperature is taken from the thermal regime records of the platinum channel, in degrees Celsius; in this embodiment, it is 1452 degrees Celsius. The viscosity is denoted as... The viscosity-temperature curve of the glass composition at that temperature was consulted; in this example, it was taken as approximately 69 Pa·s; the density was denoted as... The unit is kilograms per cubic meter, and in this embodiment, it is approximately 2350 kilograms per cubic meter.

[0033] Process target parameter: The target stirring speed is denoted as... The unit is revolutions per minute (rpm). In this embodiment, the maximum allowable stirring speed is 25 rpm.

[0034] Equipment constraint parameters: The inner diameter of the platinum mixing tank, denoted as... In this embodiment, 0.32 meters is used. All the above parameters are stored as double-precision floating-point numbers.

[0035] After data entry is complete, the validity of the entered values ​​can be verified: the working temperature of the melt should not be lower than 1380 degrees Celsius. If it is lower than this value, a prompt will be issued to the operator to request secondary confirmation; the viscosity should fall within the range of 60 to 200 Pa·s. Values ​​exceeding this range will be considered out of bounds and will be prohibited from proceeding to the next step; the density should be positive; the target stirring speed should be positive and should not exceed the set upper limit of the process; the inner diameter of the tank should be positive.

[0036] Preliminary design parameters include: the diameter of the impeller agitator is denoted as... The unit is meters, and in this embodiment, 0.275 meters is used; the number of blades per layer is denoted as... , is a positive integer, and is taken as 4 in this embodiment; the blade height is denoted as The unit is meters, and in this embodiment, it is taken as 0.025 meters; the shear area of ​​the blade shearing the molten glass is calculated based on the actual geometric dimensions of the blade's upstream surface and entered in square meters; the angle between the blade and the horizontal plane is recorded as... In this embodiment, 10 degrees is used; the number of blade layers is denoted as... , is a positive integer, and in this embodiment it is taken as 10.

[0037] Subsequently, the entered preliminary design parameters can be verified: First, check the ratio of the impeller diameter to the inner diameter of the tank. This ratio should fall within the range of 0.6 to 0.9 to achieve a balance between mixing efficiency and safe clearance between the tank walls. If the ratio exceeds this range, it will be highlighted in red on the interface, and a suggested range will be provided. Second, check the horizontal angle of the blades. This value should fall between 0 degrees and 45 degrees. Inputs exceeding the upper limit will be rejected directly. Third, check whether the number of blades and the number of layers are positive integers, and whether the blade height and shear area are positive values.

[0038] S2: Based on the preliminary design parameters, generate a three-dimensional geometric space model and determine the comprehensive geometric constants; the comprehensive geometric constants are positively correlated with the preliminary design parameters.

[0039] The shear area of ​​the blade determines the volume of molten liquid pushed by the blade per unit time, the number of blades and the number of layers determine the distribution density of shearing action in the circumferential and axial directions, and the angle between the blade and the horizontal plane determines the effectiveness of the blade's projected flow.

[0040] Therefore, based on the above parameters, the comprehensive geometric constants are determined as follows: ; in, The comprehensive geometric constants characterize the overall effect of the geometric features of the stir bar on the torque when it rotates in a viscous fluid such as TFT glass molten liquid under this specific configuration. The reference geometric base is set based on the experience of those skilled in the art. It is mainly used to adjust the mapping ratio between each preliminary design parameter and the comprehensive geometric constant. The value range is 1200 to 2000, and in this embodiment, it is 1500. is the blade cross-sectional area coefficient, which is dimensionless and means the ratio of the sum of the areas of the glass melt sheared by all blades to the horizontal cross-sectional area of ​​the mixing tank. This is the coefficient for the number of blades in a single layer. This is the blade tilt angle coefficient. This is the blade layer number coefficient.

[0041] The number of blades, the blade tilt angle, and the number of blade layers are determined according to the following relationships: ; ; ; In the formula, The number of blades per layer. The reduction value is related to the circumferential density of the blades, and the value ranges from 0.01 to 0.1. The angle between the blade and the horizontal plane, ranging from 0 degrees to 45 degrees; This refers to the number of blade layers. The value is a reduction related to the axial density of the blades, ranging from 0.01 to 0.1.

[0042] The formula for calculating the reduction value related to the axial density of the blades is as follows: ; In the formula, This represents a reduction value related to the axial density of the blades; The number of blades per layer; This represents the projected area of ​​a single blade on a plane perpendicular to the axis of rotation. Indicates the inner diameter of the platinum mixing tank; Represents pi; This indicates the spacing between the stirring rod layers. The value ranges from 0.01 to 0.1.

[0043] The formula for calculating the reduction value related to the circumferential density of the blades can be expressed as: ; In the formula, This represents a reduction value related to the circumferential density of the blades; This represents the projected area of ​​a single blade on a plane perpendicular to the axis of rotation. Indicates the inner diameter of the platinum mixing tank; This refers to the number of blades per layer; it's understandable that in actual design processes, The area will not exceed the cross-sectional area of ​​the barrel. Of course, in some embodiments, protection logic can also be set in... When the cross-sectional area of ​​the barrel is greater than that of the barrel, Set it directly to 1.

[0044] S3: Calculate the operating power of the stirring rod based on the comprehensive geometric constants and the design boundary parameters; divide the product of the operating power and the set safety margin coefficient by the transmission system efficiency to obtain the design power of the motor.

[0045] The design parameters of an electric motor include its design power.

[0046] For the required design power of the motor: First, the comprehensive geometric constants output in step S2 are received, and the operating power of the stirring rod is calculated.

[0047] ; In the formula, The operating power of the stirring rod is expressed in watts. The density of molten glass; The rotational speed of the stirring rod; The diameter of the impeller is in meters. Viscosity; It is a comprehensive geometric constant.

[0048] As can be seen from the formula, under extremely high viscosity laminar flow conditions, the stirring power is directly proportional to the square of the viscosity, the rotational speed, and the cube of the impeller diameter, while the melt density is no longer the dominant factor in power. Among these factors, the impeller diameter is the most sensitive, which provides a clear direction for geometric optimization.

[0049] The derivation process of the above formula is as follows: Understandably, the commonly used formula for calculating stirring power in the chemical industry is: ; In the formula, This indicates the stirring power of the stirring rod when stirring molten glass. This represents the power index, used to characterize the influence of the stir bar structure and flow state on the stirring power. This indicates the density of molten glass. Indicates the rotational speed of the stirring rod; This indicates the stirring diameter of the stirring rod.

[0050] The power index needs to be obtained from the Reynolds number curve. The definition of the stirring Reynolds number is: ; In the laminar flow region, the power number is expressed as the ratio of the combined geometric constant to the Reynolds number, i.e.: ; Substituting the above two equations into the general formula and rearranging, the density term is canceled out, yielding the core relationship applicable to this working condition: .

[0051] After obtaining the operating power of the stirring rod, the total load torque driving the stirring rod can be determined based on the relationship between power and torque.

[0052] The formula for calculating the total load torque can be expressed as: ; in This refers to the total load torque at the end of the stirring rod shaft; Indicates the rotational speed of the stirring rod; This indicates the stirring power when the stirring rod is used to stir the molten glass.

[0053] More specifically, to confirm the applicability of the aforementioned core relationship, a back-calculation is performed according to the Reynolds number definition while outputting the motor design parameters. Based on the design boundary parameters and preliminary design parameters of the stirring rod in this embodiment, the calculated stirring Reynolds number is approximately 0.2683, which is less than the preset threshold (set to 0.3 in this embodiment). The fact that 0.2683 is less than 0.3 indicates that the flow is in the deep laminar flow region, consistent with the applicable conditions of the power criterion relationship in the laminar flow region. In particular, when the back-calculated Reynolds number is greater than or equal to the preset threshold, it is considered that the Reynolds number is no longer significantly less than 1. At this time, an alarm is issued, the power and torque results are marked as pending verification, and the operator is prompted to back-check whether the entered viscosity value and the target speed correspond to the same operating point. This set of results cannot be used until the alarm is cleared.

[0054] Then, safety margin and transmission efficiency are taken into account based on the stirring power to determine the required design power of the motor.

[0055] Considering that the power required at the end of the stirring rod shaft is not the design power of the motor, and there is also the efficiency loss of the reducer and coupling between the two, and that once the stirring in the platinum channel stops, it may cause the homogeneity of the glass melt to deteriorate or even the channel to crystallize, the motor selection must cover the worst operating conditions, including cold start. Based on this, this step completes the conversion from load power to motor power.

[0056] The core computing engine calculates the motor's design power using the following formula: ; In the formula, The required design power for the motor, expressed in watts; The operating power of the stirring rod; The safety margin coefficient is a preset value and is dimensionless. For transmission conversion items; The efficiency of the transmission system is set by the staff based on experience, or obtained from the nameplate of the transmission component (such as the reducer).

[0057] Specifically, without considering transmission losses, the transmission system efficiency can be set to 1, and the transmission conversion term is 1. The above formula then degenerates into the form that the motor power equals the product of the safety margin coefficient and the stirring power divided by the transmission system efficiency; the safety margin coefficient is taken as 2.

[0058] More specifically, the safety margin factor is determined as follows: for cases where the channel thermal regime is stable, temperature fluctuations are small, and stirring is continuous without interruption, the value can be taken within a set lower limit range. In this embodiment, the lower limit range is [missing information]. For situations where there is a risk of cold start, such as restarting after a long period of agitation stoppage or channel cooling followed by reheating, the safety margin factor is taken within a set upper limit range. In this embodiment, the upper limit range is [value missing]. .

[0059] Finally, the selection calculation report is output, and the geometric constants of the verified configuration are written into the knowledge base for reuse.

[0060] Specifically, the relationship between torque and speed is first displayed in the form of a graph. Several speed points are selected at equal intervals above and below the target stirring speed. In this embodiment, six points are selected in the range of 5 to 30 revolutions per minute with an interval of 5 revolutions per minute. The power and torque are recalculated point by point and then connected to form a graph. This interval can be adjusted in the range of 1 to 10 revolutions per minute. The smaller the interval, the smoother the curve, but the calculation time increases accordingly.

[0061] Subsequently, the calculation results are generated, which include all input parameters, four geometric partial factors, comprehensive geometric constants, stirring rod operating power, load torque, back calculation Reynolds number, safety margin factor, transmission system efficiency, motor design power required, and final selection recommendations. These results are then saved to non-volatile memory with filenames containing configuration numbers and timestamps.

[0062] This application also discloses a motor power determination system for a TFT platinum channel stirrer, including a processor and a memory. The memory stores computer program instructions, and when the computer program instructions are executed by the processor, a motor power design method for a TFT platinum channel stirrer according to this application is implemented.

[0063] The system also includes other components well known to those skilled in the art, such as communication buses and communication interfaces, the settings and functions of which are known in the art and will not be described in detail here.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
