Abstract
Description
Technical Field
[0001] The present application relates to the technical field of curtain wall equipment, and in particular to an ink control method based on screen printing, a screen printing machine and related devices. Background Art
[0002] In order to comply with the national dual carbon policy and the aesthetic requirements of building appearance, the building exterior walls are shifting from traditional curtain walls to photovoltaic colored glaze double-glass component curtain walls that have both aesthetic and power generation functions. In this type of new curtain wall system, the surface aesthetic effect mainly depends on the colored glaze glass of the surface structure, which is made through screen printing, drying and tempering processes.
[0003] However, compared with traditional colored glaze glass, the colored glaze glass of modern photovoltaic colored glaze double-glass modules bears a dual responsibility: it must not only have high light transmittance to ensure photovoltaic power generation efficiency, but also meet the aesthetic design standards of modern buildings. This dual demand puts extremely high demands and severe challenges on the screen printing process.
[0004] In the related art, during the screen printing process, the consistency and composition ratio of the ink are affected by the ambient temperature and humidity, resulting in inconsistent consistency of the ink on each piece of glass, which in turn causes the problem of layered color difference or local color difference of the glazed glass. Specifically, changes in temperature will affect the fluidity of the ink. Increased temperature and decreased humidity will make the ink thicker and reduce its fluidity; decreased temperature and increased humidity will make the ink thinner and increase its fluidity. This change will cause the coating thickness of the ink on each piece of glass to be uneven. A low humidity and high temperature environment will make the volatile components (such as blending oil) in the ink more volatilizable, causing the ink to thicken. In addition, too low humidity and too high temperature may also cause the glass powder and toner in the ink to agglomerate, further affecting the fluidity of the ink. During the screen printing process, the ink is exposed to different temperature and humidity environments for a long time, and the glass powder and toner may precipitate or separate in the ink, resulting in an imbalance in the composition ratio of the ink. This will directly affect the consistency of the ink and the consistency of the color. The volatilization speed of blending oil is accelerated in high temperature or low humidity environment, which causes the ratio of glass powder and toner in ink to blending oil to change, thus affecting the ink's viscosity and printing effect. In particular, in the continuous printing process, when the ink reserve is insufficient to return the ink, new ink needs to be added. If the new and old inks are not mixed evenly, or the composition ratio of the new ink is different from that of the old ink, the ink composition in the screen will be inconsistent, resulting in color differences in the printed product.
[0005] Therefore, it is urgent to design a new technical solution to solve at least one of the above technical problems. Summary of the invention

[0029] In the related art, during the screen printing process, the consistency and composition ratio of the ink are affected by the ambient temperature and humidity, resulting in inconsistent consistency of the ink on each piece of glass, which in turn causes the problem of layered color difference or local color difference of the glazed glass. Specifically, changes in temperature will affect the fluidity of the ink. Increased temperature and decreased humidity will make the ink thicker and reduce its fluidity; decreased temperature and increased humidity will make the ink thinner and increase its fluidity. This change will cause the coating thickness of the ink on each piece of glass to be uneven. A low humidity and high temperature environment will make the volatile components (such as blending oil) in the ink more volatilizable, causing the ink to thicken. In addition, too low humidity and too high temperature may also cause the glass powder and toner in the ink to agglomerate, further affecting the fluidity of the ink. During the screen printing process, the ink is exposed to different temperature and humidity environments for a long time, and the glass powder and toner may precipitate or separate in the ink, resulting in an imbalance in the composition ratio of the ink. This will directly affect the consistency of the ink and the consistency of the color. The volatilization speed of blending oil is accelerated in high temperature or low humidity environment, which causes the ratio of glass powder and toner in ink to blending oil to change, thus affecting the ink's viscosity and printing effect. In particular, in the continuous printing process, when the ink reserve is insufficient to return the ink, new ink needs to be added. If the new and old inks are not mixed evenly, or the composition ratio of the new ink is different from that of the old ink, the ink composition in the screen will be inconsistent, resulting in color differences in the printed product.
[0030] Therefore, it is urgent to design a new technical solution to solve at least one of the above technical problems.
[0031] To this end, the present application provides the following embodiments to solve or improve at least some of the above problems. In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.
[0032] In some features described in the specification, claims and the above-mentioned drawings of this application, descriptions such as "first" and "second" are used to distinguish different components, parts, modules, devices, etc., and do not represent the order of precedence, nor do they limit "first" and "second" to be different types. In addition, the embodiments described below are only some embodiments of the present application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.
[0033] In order to solve the above technical problems, a screen printing machine provided in an embodiment of the present application includes the following units:
[0034] A weight sensor is used to obtain the real-time weight of the target screen printing plate;
[0035] An ink sensing module, used for determining the amount of ink to be replenished of the target screen printing screen based on the real-time weight, the original screen weight of the target screen printing screen, and the preset amount of ink required per unit screen area;
[0036] An ink supply module is used to replenish the target screen printing screen with a corresponding amount of ink based on the amount of ink to be replenished, and start an ink return operation on the target screen printing screen; after the ink return operation is completed, start an ink scraping operation on the target screen printing screen to complete a round of screen printing process for the target screen printing screen;
[0037] The weight sensor is also used to reacquire the real-time weight of the target screen printing screen after the current round of screen scraping operation is completed;
[0038] The ink sensing module is used to determine the amount of ink to be replenished of the target screen printing screen based on the re-acquired real-time weight, the original screen weight of the target screen printing screen, and the preset amount of ink required per unit screen area, and trigger the next round of screen printing process until the target screen printing screen is fully printed.
[0039] In the embodiment of the present application, the weight sensor, ink sensing module and ink supply module work together to achieve precise control and real-time adjustment of the ink volume. This solution not only improves the printing quality and production efficiency of colored glaze glass, but also reduces material and labor costs by reducing ink waste, optimizing screen design and improving operational convenience. At the same time, the environmental adaptability and environmental performance of the equipment have also been significantly improved, providing strong support for the process management level and sustainable development of the screen printing industry.
[0040] Figure 1 FIG. 1 shows a schematic diagram of the structure of a screen printing machine provided by an embodiment of the present application. Figure 1 As shown, an embodiment of the present application proposes an automatic ink supply system for a screen printing machine, which aims to control the amount of ink added, ensure that the ink used for each piece of printed colored glaze glass has a consistent consistency, solve the problem of color difference of colored glaze glass and improve the production efficiency of colored glaze glass. Figure 1 In the figure, 1 is the screen, 1-1 is the ink storage area, 1-2 is the screen printing area, 2 is the ink return knife, 3 is the scraper, 4 is the ink, 5 is the supporting base plate, 6 is the weight sensor, 7 is the weight signal sensor, 8 is the ink storage device, 8-1 is the ink storage bottle, 8-2 is the stirring rod, 8-3 is the ink storage pressurization and stirring driver, 8-4 is the filter mesh, 8-5 is the automatic control valve, and 8-6 is the ink tube.
[0041] The application process is divided into the following parts:
[0042] First, the screen printing screen should be weighed and labeled before leaving the factory. Secondly, the weight sensor senses the real-time weight of the screen and automatically deducts the weight of the screen itself. Then, the ink requirement set by the sensor minus the deducted weight is the actual ink requirement. Finally, the weight sensor transmits the actual ink requirement to the weight signal receiver.
[0043] The weight signal receiver drives the ink supply system to supply ink according to the actual ink demand; at the same time, the ink return knife starts to return ink when it senses the continuous supply of ink, and the ink supply system stops supplying ink after the return of ink. Then the screen printing scraping system starts to work. When the scraping is finished, the weight sensor recalculates the actual ink demand and transmits the information to the weight signal receiver to repeat the action until all the colored glaze glass is screen printed.
[0044] The ink supply system is equipped with stirring, pressure and filtering functions. When the weight signal receiver receives the ink demand, the stirring device is interlocked with the pressure and operates at the same time. Under the action of pressure, the ink passes through the mesh to filter out large particles, and under the action of stirring, large particles can be prevented from clogging the filter mesh. The ink passing through the mesh enters the pipeline, flows to the scraper and enters the screen, thus carrying out the screen printing process.
[0045] Therefore, the embodiment of the present application proposes an automatic ink supply system for a screen printing machine, which can accurately control the amount of ink provided according to the ink demand for one screen printing, reduce the influence of environmental temperature and humidity on the ink, ensure the consistency of the ink viscosity for each screen printing, and greatly reduce the color difference of the colored glaze glass. The automatic ink supply system of the invention reduces the time for the screen printer to add ink, effectively improving the production efficiency of the colored glaze glass. In addition, the system can reduce the ink storage area of the screen printing screen, reduce the size of the screen, reduce the amount of screen frame and mesh, reduce material utilization and cost, and has a very good effect.
[0046] The embodiment of the present application is an automatic ink supply system for a screen printing machine. The system can automatically add ink according to a weight sensor and an ink adding system, thereby automating the entire screen printing process, reducing the time for manual intermittent ink addition and improving production efficiency.
[0047] The embodiment of the present application provides an automatic ink supply system for a screen printing machine, which can accurately control the ink demand and reduce the ink storage amount on the screen, thereby reducing the area of the ink storage area and reducing the material cost of the screen. At the same time, the reduction in the size of the screen reduces the weight of the screen, reduces the effort of manually lifting the screen, makes it easier to change and wash the screen, and saves manpower.
[0048] The embodiment of the present application is an automatic ink supply system for a screen printing machine, the system uses a weight sensor, the original value of which is 1m of ink return. 2 Amount of ink required for colored glaze glass, 1 m 2 The glazed glass needs 100g of ink to return ink. Therefore, the original value of the sensor is 100g*the area of the glazed glass, and the ink demand is equal to the original value plus the added value of the screen weight. The accurate measurement of the sensor conveys the accurate ink demand to the weight signal receiver, reduces the excessive supply of ink, avoids the excessive ink from becoming thick due to the influence of environmental temperature and humidity, and solves the problems of screen blocking, stripe printing, and color difference between glazed glass.
[0049] The embodiment of the present application is an automatic ink supply system for a screen printing machine, in which the ink bottle has stirring, pressurizing and filtering functions. The stirring function is to prevent the ink from settling and keep the ink in a uniformly dispersed state at all times; the pressurizing function simulates the use of a scraper with a certain pressure to screen-print the ink onto the glass through the mesh. The same principle of pressurizing allows fine particles of ink to pass through the mesh into the screen, and the coarse particles are still dispersed in the ink bottle under stirring, and will not be deposited on the mesh to block the mesh, and will not enter the screen to block the screen. In addition, the ink is stored in the ink bottle and is not affected by the ambient temperature and humidity, ensuring that the ink provided each time has the same viscosity. Therefore, the system solves the problem of ink clogging the screen and the color difference problem caused by different consistencies.
[0050] It should be added here that the control logic of the control device will be introduced in detail in the method embodiment below.
[0051] An embodiment of the present application provides an ink control method based on screen printing. The execution subject of the method described in this embodiment can be the ink control device in the above embodiment, which is implemented on the basis of the structure of the above screen printing machine embodiment. Figure 2 As shown, the method may include the following steps:
[0052] 101. Obtain the real-time weight of the target screen printing plate through a weight sensor;
[0053] 102. Determine the amount of ink to be replenished of the target screen printing screen by an ink sensing module based on the real-time weight, the original screen weight of the target screen printing screen, and the preset amount of ink required per unit screen area;
[0054] 103. Replenishing a corresponding amount of ink to the target screen printing plate based on the amount of ink to be replenished through an ink supply module, and starting an ink return operation for the target screen printing plate;
[0055] 104. After the ink return operation is completed, start the screen scraping operation on the target screen printing screen to complete a screen printing process for the target screen printing screen;
[0056] 105. After the current round of screen scraping operation is completed, reacquire the real-time weight of the target screen printing plate through the weight sensor;
[0057] 106. Determine the amount of ink to be replenished of the target screen printing screen based on the re-acquired real-time weight, the original weight of the screen, and the amount of ink required per unit screen area through the ink sensing module, and trigger the next round of screen printing process until the target screen printing screen is fully printed.
[0058] The present application provides an ink control method based on screen printing, which realizes precise control and real-time adjustment of the amount of ink on the screen printing plate through the coordinated work of a weight sensor, an ink sensing module and an ink supply module, thereby significantly improving the quality and production efficiency of colored glaze glass screen printing.
[0059] In the traditional screen printing process, the addition of ink usually relies on manual operation. This method is not only time-consuming and labor-intensive, but also prone to errors due to inconsistent operations. The present application eliminates the time and labor intensity of manually adding ink through an automated ink supply system, significantly improving production efficiency. Specifically, in the traditional screen printing process, the printing press needs to be stopped every time the ink is insufficient, and the operator manually adds ink. This process is not only time-consuming, but may also affect the quality and continuity of printing. The automatic ink supply system of the present application can immediately start the ink supply and ink return operation when insufficient ink is detected, reducing downtime and improving production continuity. The automated system can replace manual operation, reduce dependence on operators, and reduce labor costs. This effect is particularly significant in large-scale production. Operators can devote more time and energy to other key links to improve overall production efficiency.
[0060] The present application ensures that the amount and consistency of ink on each piece of glass are consistent by real-time monitoring and adjustment of the ink amount, thereby significantly improving the printing quality. The consistency of the ink directly affects the color consistency of the printed product. In the traditional screen printing process, due to changes in ambient temperature and humidity and the imbalance of the ink composition ratio, the ink consistency of each piece of glass may be different, resulting in layered color difference or local color difference in the glazed glass. The automatic ink supply system of the present application ensures that the ink consistency on each piece of glass is consistent by accurately controlling the ink amount, effectively reducing the color difference problem. Large particle materials are easy to clog the mesh and affect the printing effect. The ink supply system of the present application is equipped with stirring, pressurization and filtering functions to ensure that the large particle materials in the ink are dispersed in the ink bottle under stirring, and are not deposited in the mesh and clogged. This not only improves the printing quality, but also extends the service life of the screen. Inconsistent ink consistency may also cause stripe printing during the printing process. The present application ensures that the ink is evenly distributed on the screen by real-time monitoring and adjustment of the ink amount, thereby avoiding the generation of stripe printing.
[0061] The ink control method of the present application not only improves the printing quality, but also effectively reduces the material cost by reducing ink waste and optimizing the screen design. In the traditional screen printing process, the addition of ink is usually based on experience and estimation, which easily leads to ink waste or insufficient. The present application ensures that the amount of ink added each time is just right by real-time monitoring and precise control of the amount of ink, thereby reducing ink waste and reducing material costs.
[0062] Since the ink control method of the present application can adjust the ink amount in real time, the ink storage area on the screen can be designed to be smaller. This not only saves the amount of screen material, but also reduces the weight of the screen, making the operation more convenient. At the same time, the reduction in screen size also helps to reduce the amount of screen frame and mesh, further reducing material costs. The reduction in screen size and precise control of ink reduce the frequency and difficulty of cleaning the screen, thereby reducing the cleaning cost and material loss during the cleaning process.
[0063] The automatic ink supply system of the present application not only improves production efficiency and printing quality, but also improves the convenience of operation by optimizing the operation process. Traditional manual addition of ink requires operators to frequently weigh, add and adjust, and the operation steps are cumbersome. The automatic ink supply system of the present application simplifies the operation steps. The operator only needs to start the system, and the system will automatically complete the addition and adjustment of ink, which greatly reduces the burden on the operator. The automated ink supply system reduces the frequency and intensity of manual intervention, making the operation simpler and safer. Operators can focus more on other production links, improving the convenience and safety of the overall operation. The reduction in screen size and the reduction in weight make the operation of changing screens more convenient and quick. Operators no longer need to spend a lot of time and effort when changing screens, which improves the efficiency of changing screens.
[0064] The automatic ink supply system of the present application monitors and adjusts the ink volume in real time through precise weight sensors and ink sensing modules, thereby enhancing the stability and reliability of the system. The weight sensor can detect the weight changes of the screen in real time and accurately, and provide reliable feedback data for the ink supply system. The high-precision and high-frequency data acquisition capabilities of the sensor ensure that the system can quickly respond to changes in ink demand. The ink sensing module automatically calculates the amount of ink to be replenished based on the real-time data provided by the weight sensor and the preset process parameters. The system accurately controls the ink supply based on the calculation results, avoiding the uncertainty of human operation and improving the stability and reliability of the system. By monitoring the ink volume and screen status in real time, the system can promptly detect abnormal situations, such as insufficient ink in the ink bottle, mesh blockage, etc., and perform preventive maintenance, avoiding shutdowns due to equipment failures during production, and improving the operating efficiency of the system.
[0065] The automatic ink supply system of the present application has strong environmental adaptability and can maintain the consistency and stability of the ink under different temperature and humidity conditions. Temperature and humidity will affect the fluidity of the ink, resulting in different ink consistencies. Traditional manual operations cannot accurately control the ink consistency and are easily affected by ambient temperature. The present application monitors and adjusts the amount of ink in real time to ensure that the amount of ink provided each time is consistent with the consistency, thereby reducing the impact of temperature on the printing effect. Changes in humidity will affect the volatilization rate of volatile components in the ink, resulting in changes in the ink consistency. The ink supply system of the present application stores the ink in an ink bottle, avoiding the accelerated volatilization rate caused by direct exposure of the ink to high temperature or low humidity environments, thereby reducing changes in the ink consistency. At the same time, the stirring function of the system can prevent the precipitation and separation of the components in the ink, ensuring that the ink is always in a uniformly dispersed state.
[0066] The ink control method of the present application not only improves production efficiency and printing quality, but also improves environmental performance by reducing ink waste. In the traditional screen printing process, the addition and adjustment of ink are often imprecise, which easily leads to ink waste. The present application reduces unnecessary ink addition and ink waste by accurately controlling the amount of ink. This not only saves material costs, but also reduces pollution to the environment. The reduction in screen size and the precise control of ink reduce the frequency and amount of water used to clean the screen, thereby reducing the consumption of water resources during the cleaning process and improving environmental performance.
[0067] The ink control method of the present application improves the process management level through automated and intelligent technical means, making the production process more controllable and efficient. The control system can record the data of each ink addition and printing operation in real time, which is convenient for subsequent analysis and optimization. The operator can find abnormal conditions in the production process through data analysis, make adjustments in time, and improve the process management level. The automated ink supply system realizes the standardization of ink addition and avoids the inconsistency caused by manual operation. This makes the production process more standardized and improves the quality and reliability of the product. By connecting to the company's internal monitoring system, the operator can remotely monitor the production process and understand the operating status of the equipment and the use of ink in real time. This not only improves the efficiency of production management, but also enhances the transparency and traceability of production.
[0068] In summary, the ink control method based on screen printing proposed in this application realizes precise control and real-time adjustment of the ink amount through the coordinated work of the weight sensor, the ink sensing module and the ink supply module. This method not only improves the printing quality and production efficiency of the colored glaze glass, but also reduces the material cost and labor cost by reducing ink waste, optimizing the screen design and improving the convenience of operation. At the same time, the environmental adaptability and environmental protection performance of the system have also been significantly improved, providing strong support for the process management level and sustainable development of the screen printing industry.
[0069] As an optional embodiment, in 101, before obtaining the real-time weight of the target screen printing screen through the weight sensor, the original weighing information of each newly added target screen printing screen can be collected through the weight sensor. Then, the original weighing information is converted into a screen weight label, and the screen weight label is marked on the newly added target screen printing screen, and the screen weight label is used to indicate the weight information of the newly added target screen printing screen itself.
[0070] In an optional embodiment of the present application, before obtaining the real-time weight of the target silk screen printing screen through the weight sensor, a step of collecting the original weighing information of each newly added target silk screen printing screen is added. Specifically, when a new silk screen printing screen is added to the printing system, it is first weighed by the weight sensor to record the original weight information of the screen. Subsequently, this original weighing information is converted into a screen weight label, and the screen weight label is marked on the newly added target silk screen printing screen. This screen weight label is used to indicate the weight information of the newly added screen itself, so that in the subsequent ink supply and printing process, the system can accurately identify and process the weight changes of each screen.
[0071] The principle of this embodiment is to provide basic data for the subsequent calculation of ink demand by pre-collecting and marking the original weight information of the screen. When a new screen is added to the system, the weight sensor weighs it with high precision to ensure the accuracy of the initial weight. Then, these initial weight data are converted into a screen weight label and stored in the system database. During the actual printing process, the weight sensor monitors the total weight of the screen in real time and transmits the real-time weight data to the control system. The control system obtains the real-time weight of the ink on the current screen by subtracting the original weight of the screen. Based on this real-time weight and the preset unit area ink demand, the control system accurately calculates the amount of ink to be replenished, thereby achieving accurate ink supply and ink return operations.
[0072] The beneficial effects of this embodiment are very significant. First, by pre-collecting and marking the original weight information of the screen, the system can accurately identify the initial state of each screen, avoiding errors caused by different screen weights. This ensures the accuracy of each ink supply and ink return operation, and improves the consistency of printing quality. Secondly, since the original weight information of the screen has been accurately recorded and marked, the system can quickly and accurately calculate the amount of ink to be replenished during each printing process, reducing the uncertainty and complexity of manual operation. This not only improves production efficiency, but also reduces the labor intensity and difficulty of operation of operators. In addition, by real-time monitoring of the weight change of the screen, the system can adjust the ink supply in time to prevent excessive or insufficient supply of ink, avoiding color difference and printing quality problems caused by inconsistent ink consistency. This method can also effectively prevent large particles from clogging the mesh, ensure the uniform distribution of ink, and further improve the printing effect.
[0073] In summary, by pre-collecting and marking the original weight information of the newly added target silk screen printing screen, the ink control method of the present application not only realizes the precise control and real-time adjustment of the ink amount, but also improves the production efficiency, printing quality and process management level, reduces material cost and labor cost, and has high practical value and market application prospects.
[0074] As an optional embodiment, in 101, obtaining the real-time weight of the target screen printing plate through a weight sensor can be implemented as follows:
[0075] The real-time weighing information of the target screen printing plate is collected by a weight sensor as the real-time weight.
[0076] Furthermore, in 102, based on the real-time weight, the original weight of the target screen printing screen, and the preset ink quantity required per unit screen area, determining the ink quantity to be replenished of the target screen printing screen can be implemented as follows:
[0077] 201. According to the identification of the target screen printing screen, select a screen weight label corresponding to the target screen printing screen from a pre-established screen weight label library;
[0078] 202. Reading a screen weight label corresponding to the target screen printing screen, and using the weight information indicated by the read screen weight label as the original weight of the screen;
[0079] 203. The real-time weight, the original weight of the target screen printing screen, and the ink quantity required per unit screen area are converted in a preset manner to obtain a candidate amount of ink to be supplemented for the target screen printing screen;
[0080] 204. Input the candidate amount of ink to be supplemented into an ink quality correction model; the ink quality correction model is trained by historical ink usage data of the silk screen printing screen;
[0081] 205. Predicting the actual demand for the target screen printing screen by using the ink quality correction model to obtain a predicted value of the amount of ink to be replenished for the target screen printing screen;
[0082] 206. Correct the candidate ink replenishment amount based on the predicted value to obtain the ink replenishment amount of the target screen printing plate.
[0083] The specific principles and technical effects of steps 201 to 206 are described below with reference to examples.
[0084] In an optional embodiment of the present invention, the step of obtaining the real-time weight of the target screen printing screen through the weight sensor is further refined as follows: collecting the real-time weighing information of the target screen printing screen through the weight sensor and using it as the real-time weight. This step ensures that the system can obtain the ink weight change on the screen in real time and accurately, providing reliable basic data for subsequent ink replenishment and printing operations. Then, in the process of determining the amount of ink to be replenished on the target screen printing screen, the specific steps are as follows:
[0085] First, according to the target screen printing screen identification, select the screen weight label corresponding to the target screen printing screen from the pre-established screen weight label library. The screen weight label library is a database that stores the original weight information of each screen. The original weight information of each screen is collected by a high-precision weight sensor when the screen is used for the first time, and stored with the screen identification as the index. In this way, the system can quickly and accurately read the original weight information of the screen every time it is used.
[0086] Next, read the screen weight tag corresponding to the target screen printing screen, and use the weight information indicated by the read screen weight tag as the original weight of the screen. This step ensures that when calculating the ink requirement, the system uses the calibrated and verified original weight data, avoiding calculation errors caused by using inaccurate original data.
[0087] Then, the real-time weight, the original weight of the target screen printing screen and the preset amount of ink required per unit screen area are converted into the candidate amount of ink to be added to the target screen printing screen. This conversion method is usually a formula based on difference calculation, for example: Candidate amount of ink to be added = ink required per unit screen area * screen area - (real-time weight - original weight of screen). Through this formula, the system can preliminarily calculate the amount of ink that needs to be added.
[0088] To further improve the accuracy of ink replenishment, the candidate replenishment ink amount is input into the ink quality correction model. The ink quality correction model is a machine learning model trained based on historical ink usage data. By analyzing a large amount of historical data, the model learns the ink usage rules of different types and sizes of screens under different printing conditions, and can correct the initially calculated candidate replenishment ink amount to improve its accuracy.
[0089] The actual demand for the target screen printing screen is predicted through the ink quality correction model, and the predicted value of the amount of ink to be replenished for the target screen printing screen is obtained. This predicted value not only takes into account the difference between the real-time weight and the original weight, but also combines the ink usage rules in the historical data, which can more accurately reflect the actual amount of ink required. This step ensures that the amount of ink replenished is more in line with the actual demand and avoids printing quality problems caused by too much or too little ink.
[0090] Finally, the candidate ink replenishment amount is corrected based on the predicted value to obtain the final target screen printing screen ink replenishment amount. This correction process further improves the accuracy of ink replenishment and ensures that the ink amount of each printing operation is consistent, thereby improving printing quality and production efficiency.
[0091] The principle of this optional embodiment is to ensure the high accuracy and reliability of the ink demand data obtained by the system through multiple steps of layered correction and verification. First, the real-time weighing information is collected through the weight sensor to monitor the change of ink weight on the screen in real time; second, the original weight information of the screen is obtained through the screen weight label library to ensure the accuracy of the calculation basic data; then the candidate replenishment ink quantity is preliminarily calculated through the preset conversion formula; finally, the actual demand quantity is predicted through the ink quality correction model, and the candidate replenishment ink quantity is corrected to ensure that the final replenishment ink quantity meets the actual demand.
[0092] The beneficial effects of this embodiment are very significant. First, through accurate real-time weight monitoring and storage of original weight information, the system can accurately calculate the change in ink weight on each screen, avoiding printing quality problems caused by inaccurate data. Secondly, the introduction of the ink quality correction model, using historical data for prediction and correction, further improves the accuracy of ink replenishment, ensures the consistency of ink volume in each round of printing operation, and improves the quality and consistency of printed products. In addition, this embodiment not only reduces the uncertainty and complexity of manual operation, but also effectively improves production efficiency and operational convenience and reduces production costs through automation and intelligent means. Finally, by reducing ink waste and optimizing ink supply.
[0093] As an optional embodiment, in 203, the real-time weight, the original weight of the target silk screen screen, and the amount of ink required per unit screen area are converted using a preset method to obtain a candidate amount of ink to be replenished for the target silk screen screen. This can be implemented as follows: the candidate amount of ink to be replenished is obtained by taking the difference between the real-time weight and the original weight of the screen, and multiplying the difference by the amount of ink required per unit screen area.
[0094] In the above optional embodiment, the total weight of the target screen printing screen, including the screen and the ink thereon, is collected in real time by a weight sensor. The original weight information of the screen is read from a pre-established screen weight label library. This original weight information is collected by a high-precision weight sensor and stored in a database when the screen is used for the first time. The real-time weight is subtracted from the original weight of the screen to obtain the real-time weight change of the ink on the current screen. That is: difference = real-time weight - original weight of the screen. This is a preset parameter determined based on actual production experience and test data. It represents the amount of ink required per unit area of the screen during the printing process. The above difference is multiplied by the amount of ink required per unit screen area to obtain the candidate amount of ink to be replenished for the target screen printing screen. That is: candidate amount of ink to be replenished = difference * amount of ink required per unit screen area.
[0095] The principle of this conversion method is simple and clear. By calculating the difference between the real-time weight and the original weight of the screen, combined with the amount of ink required per unit screen area, the amount of ink to be replenished can be accurately calculated. By calculating the difference between the real-time weight and the original weight of the screen, the system can accurately reflect the change in the amount of ink on the current screen. This difference calculation method avoids errors caused by changes in the weight of the screen itself (for example, aging or wear of the screen), ensuring the accuracy of ink calculation. Traditional ink replenishment methods rely on the experience and judgment of operators, and are easily affected by human factors, resulting in inconsistent ink replenishment.
[0096] This embodiment performs calculations in an automated and formulaic manner, thereby reducing errors caused by human operation and improving the consistency and reliability of the system. The real-time weight sensor can frequently provide weight change data on the screen, and the system can promptly and accurately calculate the amount of ink that needs to be replenished and replenish it immediately. This real-time adjustment ensures that the amount of ink in each round of printing operation is always in the best state, avoiding printing quality problems caused by insufficient or excessive ink. Precise control of the amount of ink makes the ink distribution on each piece of glass more even, reducing problems such as color difference and stripe printing caused by inconsistent ink consistency. In addition, by accurately replenishing the ink, large particles can also be prevented from clogging the mesh, further improving the printing quality. The calculation of the candidate replenishment amount of ink is based on the actual ink demand, avoiding unnecessary waste of ink.
[0097] In the traditional method, due to the inaccurate addition of ink, the ink is often overused or underused, which increases the production cost. This embodiment optimizes the use of ink and saves material costs through precise calculation and replenishment. Different screen printing screens may have different original weights. By pre-collecting and marking the original weight information of each screen, this embodiment can better adapt to various types of screens. When calculating the ink demand, the system can make adjustments based on the specific original weight of the screen to ensure consistency and accuracy. By reducing human intervention and improving the accuracy of ink replenishment, the situation of frequent shutdowns for ink replenishment due to insufficient ink is reduced. Operators can devote more time and energy to other production links, improving overall production efficiency. In this embodiment, the data of each ink replenishment and printing operation are recorded in the system, which is convenient for subsequent data analysis and process optimization. Operators can use these data to discover abnormal conditions in the production process and make timely adjustments, thereby improving the level of process management.
[0098] In summary, by calculating the difference between the real-time weight and the original weight of the screen, and combining the amount of ink required per unit screen area, this embodiment not only achieves precise control of the amount of ink, but also significantly improves printing quality, production efficiency and process management level, reduces material costs and labor costs, and has high practical value and broad application prospects.
[0099] As an optional embodiment, it is assumed that the ink quality correction model includes at least the following structures: a preprocessing layer, a prediction layer, and an optimization layer. Based on the above structure, the actual demand quantity of the target screen printing screen is predicted by the ink quality correction model to obtain the predicted value of the amount of ink to be replenished of the target screen printing screen, which can be implemented as follows:
[0100] Step 1: Identify the printing type of the target screen printing plate through the pre-treatment layer;
[0101] Step 2: Selecting a corresponding target prediction branch from multiple prediction branches according to the printing type through the prediction layer, and predicting the actual demand for the target screen printing plate through the target prediction branch to obtain the predicted value of the amount of ink to be replenished;
[0102] Step three: optimizing the predicted value of the amount of ink to be replenished of the target screen printing plate through the optimization layer, and outputting the optimized predicted value of the amount of ink to be replenished.
[0103] In an optional embodiment of the present invention, it is assumed that the ink quality correction model includes at least the following structures: a preprocessing layer, a prediction layer, and an optimization layer. Based on these structures, the process of predicting the actual demand of the target screen printing screen and obtaining the predicted value of the amount of ink to be replenished through the ink quality correction model can be implemented as follows: first, the printing type to which the target screen printing screen belongs is identified through the preprocessing layer; then, the corresponding target prediction branch is selected from multiple prediction branches according to the printing type through the prediction layer, and the actual demand of the target screen printing screen is predicted through the target prediction branch to obtain the predicted value of the amount of ink to be replenished; finally, the predicted value of the amount of ink to be replenished of the target screen printing screen is optimized through the optimization layer, and the optimized predicted value of the amount of ink to be replenished is output.
[0104] The main task of the pre-processing layer is to identify the type of printing that the target screen belongs to. Printing types can include different screen materials, screen sizes, printing speeds, ink types, etc. This identification process analyzes the real-time weight data and screen identification information, combined with the pre-stored screen data and printing process parameters to determine the type of printing of the screen. The pre-processing layer may also include steps such as data cleaning and format conversion to ensure that the data input to the prediction layer is of high quality and consistent format.
[0105] The prediction layer contains multiple prediction branches, each of which corresponds to a specific printing type. These prediction branches are trained with a large amount of historical data and can learn and simulate the ink usage rules under different printing types. Furthermore, according to the printing type identified by the preprocessing layer, the prediction layer selects the corresponding target prediction branch from multiple prediction branches. This selection process ensures the pertinence and accuracy of the prediction model. Furthermore, the actual demand for the target screen printing screen is predicted through the target prediction branch to obtain the predicted value of the amount of ink to be replenished. Based on historical data, the prediction model can consider multiple factors (such as printing speed, ambient temperature, screen wear, etc.) to provide more accurate prediction results.
[0106] The optimization layer further optimizes the predicted value of the amount of ink to be replenished obtained by the prediction layer. The optimization process may include smoothing the prediction results, detecting and correcting outliers, and adjusting in combination with real-time production feedback data. The optimization layer finally outputs the optimized predicted value of the amount of ink to be replenished to ensure that the final amount of ink replenishment is more in line with actual needs.
[0107] In the above embodiment, the high accuracy and reliability of the ink replenishment amount are ensured through the layer-by-layer processing of the preprocessing layer, the prediction layer and the optimization layer. First, the preprocessing layer provides accurate classification information for subsequent predictions by identifying the printing type of the screen, avoiding the mixing of ink requirements of different printing types and improving the pertinence of the prediction. The data preparation step of the preprocessing layer also ensures the quality of the input data, laying the foundation for the accurate prediction of the prediction model.
[0108] Next, the prediction layer uses multiple prediction branches to select the most appropriate target prediction branch based on the printing type identified by the preprocessing layer. This selection process enables the model to better adapt to different types of screens and printing conditions, improving the accuracy of prediction. The prediction model is trained based on a large amount of historical data and can learn and simulate the ink usage rules under various printing types, thereby providing more reasonable prediction results. This not only reduces the uncertainty of human intervention, but also improves the automation level of the system.
[0109] Finally, the predicted value is further optimized through the optimization layer. The system can smooth the predicted results and correct outliers, and dynamically adjust them in combination with real-time production feedback data to ensure that the final ink replenishment amount is more in line with actual needs. The optimization process makes the prediction results more stable and reliable, avoiding the problem of unstable ink supply caused by fluctuations in the predicted values.
[0110] In the above embodiment, through the classification identification and data preparation of the preprocessing layer, and the multi-prediction branch selection and historical data training of the prediction layer, the system can provide high-precision prediction of ink demand, ensuring that the amount of ink for each screen is always in the best state during the printing process. The entire prediction and optimization process is highly automated, reducing the human intervention of operators, avoiding ink replenishment errors caused by lack of experience or operating errors, and improving the reliability and consistency of the system. The design of multiple prediction branches enables the system to better adapt to different types of screens and printing conditions, improving the intelligence level and flexibility of the system. The optimization layer optimizes the predicted value through real-time feedback data, ensuring the dynamic adjustment ability of the system during the production process, correcting the prediction deviation in time, and improving the printing quality and production efficiency. The precise control of the ink amount makes the ink distribution on each screen more uniform, reduces printing quality problems such as color difference and stripe printing, and improves the consistency and stability of the product. Through accurate ink replenishment, excessive use and waste of ink are avoided, and material costs are reduced. At the same time, the downtime caused by insufficient or excessive ink is reduced, the production efficiency is improved, and the labor cost is reduced.
[0111] In summary, the above embodiments can significantly improve the accuracy, quality and efficiency of screen printing on colored glaze glass, reduce production costs and improve the level of process management.
[0112] In the embodiment of the present application, the prediction branch is expressed as the following formula: .in, It is the actual demand of the target screen printing plate predicted according to the specific printing type S. The subscript t is the identifier of the prediction branch, and each branch corresponds to a specific printing type. Represents the actual ink demand of the ith historical sample. These historical samples are extracted from a large amount of historical data, and each sample represents the actual demand for ink replenishment for a certain screen under specific conditions. Indicates the difference between the target screen printing screen and the i-th historical sample. The difference refers to the difference between the current screen and the historical sample in printing conditions (such as printing speed, ambient temperature, humidity, etc.). The greater the difference, the lower the reference value of the historical sample to the current screen. is a Gaussian weight function used to Actual ink demand for historical samples When When smaller, Close to 1, the weight is large; when When larger, Closer to 0, the weight is smaller. This function makes the historical samples closer to the current printing conditions have a greater impact on the prediction results. n represents the total number of historical samples used for prediction. These historical samples are selected from the pre-stored data set and match the printing type of the current target screen printing screen.
[0113] By dynamically adjusting the weights, the model is able to reduce the prediction bias caused by using irrelevant historical samples. Only those historical samples that are closest to the current screen printing conditions are given higher weights, thereby improving the reliability of the prediction.
[0114] Thus, through the combination of the preprocessing layer, the prediction layer and the optimization layer, a high-precision prediction of the ink demand is achieved. Specifically, by weighting the historical samples with the Gaussian weight function, the model can more accurately predict the amount of ink to be replenished for the target screen printing screen. Especially when the number of historical samples is large, the weighted average method can effectively reduce the impact of the error of individual samples on the overall prediction results. Dynamic adjustment of weights enables the model to adapt to various printing conditions, improving the flexibility and intelligence level of the system. Even for new printing types or environmental conditions, the model can provide reasonable prediction results through learning and weighted adjustment of historical data. The entire prediction process is highly automated, reducing the human intervention of operators, avoiding prediction deviations caused by lack of experience or operational errors, and improving the reliability and consistency of the system. Through accurate prediction and optimization, the system can ensure that the amount of ink on each screen is always in the best state during the printing process, avoiding waste and shortage of ink, and reducing production costs. The precise control of the ink amount makes the ink distribution on each screen more uniform, reduces printing quality problems such as color difference and stripe printing, and improves the stability and consistency of the product. Each historical sample weight calculation and final prediction result in the prediction process are recorded to facilitate subsequent data analysis and process optimization. Operators can use these data to discover abnormal situations in the production process and make timely adjustments, thus improving the level of process management.
[0115] In summary, the above embodiment weights historical samples through a Gaussian weight function, and the system can more accurately and reliably predict the amount of ink to be replenished for the target screen printing plate, further optimizing the production process of colored glaze glass screen printing.
[0116] In the embodiment of the present application, different prediction branches have different structural adjustment factors, and the structural adjustment factors are used to control the fluctuation range of the screen printing ink demand corresponding to each printing type; the acquisition process of the structural adjustment factor of the T-th prediction branch is expressed as the following formula:
[0117]
[0118] in, is the structural adjustment factor of the Tth prediction branch, E represents the comprehensive influence of multiple current environmental and process parameters, T represents the temperature in the actual production environment, Indicates the temperature at which the ink performs best under a certain printing type. represents the standard deviation of temperature values, Used to indicate the sensitivity of temperature to fluctuations in ink demand, Indicates the humidity in the actual production environment. It is the humidity at which the ink performs best under a certain printing type. Indicates the sensitivity of humidity to fluctuations in ink demand, Indicates the ink concentration in actual production. It is the concentration at which the ink has the best performance under a certain printing type. Indicates the sensitivity of ink concentration to fluctuations in ink demand, is the standard deviation of the ink concentration values.
[0119] Therefore, through the structural adjustment factor, the system can accurately control the fluctuation range of ink demand in each forecast branch. The fluctuation range of ink demand for different printing types may be different, and the structural adjustment factor can dynamically adjust these fluctuation ranges to ensure the accuracy of the forecast results.
[0120] The multiple parameters in the above formula (temperature, humidity, printing speed, ink concentration) take into account various influencing factors in actual production, so that the model can better adapt to changes in ink demand under different printing conditions. Even for new printing conditions or environmental parameters, the system can make reasonable predictions through adjustment factors. Furthermore, by weighting each parameter through the Gaussian weight function, the system can reduce the prediction deviation caused by changes in individual parameters. Only when multiple parameters change significantly at the same time will the adjustment factor change significantly, thereby ensuring the stability and reliability of the prediction results.
[0121] The precise control of ink demand makes the ink distribution on each screen more uniform, reduces printing quality problems such as color difference and streak printing, and improves the stability and consistency of the product.
[0122] The dynamic calculation and application of structural adjustment factors enables the system to continuously optimize the prediction and replenishment of ink demand during the production process. This not only improves production efficiency, but also reduces downtime caused by insufficient or excessive ink, further improving the intelligence level of the system. Each calculation process of the adjustment factor is recorded to facilitate subsequent data analysis and process optimization. Operators can use this data to discover abnormal situations in the production process and make timely adjustments, thereby improving the level of process management.
[0123] In summary, by comprehensively considering multiple environmental and process parameters and dynamically adjusting the fluctuation range of the prediction results, the accuracy and reliability of the ink demand prediction are improved. This not only optimizes the production process of colored glaze glass screen printing, but also significantly improves printing quality and production efficiency, and reduces production costs.
[0124] As an optional embodiment, in 103, after the ink supply module replenishes the target silk screen with a corresponding amount of ink based on the amount of ink to be replenished and starts the ink return operation on the target silk screen, the type of ink material in the ink supply module can be determined; based on the ink material type and the current production environment parameters, the stirring speed of the ink material is dynamically adjusted; based on the stirring speed, a stirring trigger instruction is generated in real time to enable the ink material in the ink supply module to perform an automatic stirring function at a corresponding stirring speed to prevent ink precipitation.
[0125] In an optional embodiment of the present invention, after the ink supply module replenishes the target silk screen with a corresponding amount of ink based on the amount of ink to be replenished and starts the ink return operation, the type of ink material in the ink supply module can be further determined; based on the ink material type and the current production environment parameters, the stirring speed of the ink material is dynamically adjusted; based on the stirring speed, a stirring trigger instruction is generated in real time to enable the ink material in the ink supply module to perform an automatic stirring function at a corresponding stirring speed to prevent ink precipitation.
[0126] First, the inks stored in the ink supply module usually have different material types, such as water-based inks, solvent-based inks, UV inks, etc. Through ink identification or other methods (such as sensor detection), the system can accurately identify the type of ink material currently in use. An ink material database is pre-established in the system, which stores the characteristics of various ink materials, including their appropriate stirring speed range, sensitivity to ambient temperature and humidity, etc. The current production environment parameters include temperature, humidity, printing speed, etc., which affect the fluidity, drying speed and stability of the ink.
[0127] Then, the system dynamically calculates the appropriate stirring speed based on the ink material type and the current production environment parameters. This calculation process can be based on a pre-established algorithm model, taking into account the physical properties of the ink and the influence of environmental factors. For example, when the temperature is high, the fluidity of the ink is poor, and the stirring speed may need to be increased; when the humidity is low, the ink is easy to absorb moisture, and the stirring speed also needs to be adjusted appropriately.
[0128] The system generates a stirring trigger command in real time based on the calculated stirring speed and sends it to the stirring device in the ink supply module. After receiving the stirring trigger command, the stirring device performs the automatic stirring function at the specified stirring speed to ensure that the ink is always in a uniform state and prevent the ink from settling due to long-term standing.
[0129] Thus, by determining the ink material type, dynamically adjusting the stirring speed, and generating stirring trigger instructions in real time, it is ensured that the ink material in the ink supply module is always in the best state. First, through the ink identification and material database, the system can accurately identify the type of ink material currently in use. This identification process provides basic data for the subsequent adjustment of the stirring speed. Then, the system dynamically calculates the appropriate stirring speed based on the ink material type and the current production environment parameters. This adjustment process takes into account the physical properties of the ink and the influence of environmental factors, ensuring the stability and fluidity of the ink. Finally, the system generates stirring trigger instructions in real time, so that the stirring device can perform the automatic stirring function in a timely and accurate manner to prevent the ink from settling during the static process.
[0130] In this way, through real-time stirring, the ink always maintains a uniform state, avoiding printing quality problems caused by ink precipitation. Real-time stirring is particularly important for some ink materials that are easy to stratify or precipitate. The uniformity of the ink directly affects the printing effect. By dynamically adjusting the stirring speed, the system can ensure the consistency of the quality of each drop of ink, further improving the consistency and stability of printing. The entire stirring process is highly automated, reducing the intervention of operators, avoiding insufficient or excessive stirring due to human operating errors, and improving the reliability and consistency of the system. Different production environment parameters (such as temperature and humidity) will affect the performance of the ink. By dynamically adjusting the stirring speed, the system can better adapt to various production environments and ensure the stability of ink supply and printing quality. Real-time generation of stirring trigger instructions enables the stirring device to respond in time, reducing the time required for downtime cleaning due to ink precipitation, and improving production efficiency. By accurately controlling the stirring speed, wear and energy waste caused by excessive stirring of the ink is avoided, reducing production costs. At the same time, the need to readjust the ink due to ink precipitation is reduced, saving material and time costs. Every stirring operation and environmental parameters are recorded for subsequent data analysis and process optimization. Operators can use these data to discover abnormal situations in the production process and make timely adjustments, thereby improving the level of process management.
[0131] In summary, by determining the ink material type, dynamically adjusting the stirring speed and generating stirring trigger instructions in real time, the system can ensure the stability of ink supply and printing quality, improve production efficiency, reduce production costs, and further optimize the production process of colored glaze glass screen printing.
[0132] As an optional embodiment, in the above steps, after a stirring trigger instruction is generated in real time based on the stirring speed so that the ink material in the ink supply module performs an automatic stirring function at a corresponding stirring speed, the stirring speed can also be input into a pressure following model after the automatic stirring function is started to obtain pressurization information that matches the stirring speed. In the embodiment of the present application, the pressurization information is used to indicate the pressure value required to be applied when filtering the ink material. Furthermore, a pressure device control instruction is generated based on the pressurization information so that the ink material is pressurized and filtered through a mesh filter provided in the ink supply module to remove large particles in the ink material.
[0133] In the embodiment of the present application, the weight sensor, ink sensing module and ink supply module work together to achieve precise control and real-time adjustment of the ink volume. This solution not only improves the printing quality and production efficiency of colored glaze glass, but also reduces material and labor costs by reducing ink waste, optimizing screen design and improving operational convenience. At the same time, the environmental adaptability and environmental performance of the equipment have also been significantly improved, providing strong support for the process management level and sustainable development of the screen printing industry.
