Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and more particularly to an advanced mesh device, method and controller for pressurized ink filtering. Background Art

[0002] In the process of photovoltaic glass screen printing, the quality of ink plays a vital role in the pattern clarity and consistency of the final product. However, the existing technology has many shortcomings in removing large particle impurities in the ink. Traditional filtering devices usually use filter mesh made of a single material with a large pore size, which makes it difficult to effectively intercept larger particle impurities in the ink. These unfiltered particles are easy to clog the screen during the screen printing process, causing pattern defects and even equipment failure. At the same time, when processing high-viscosity inks, existing devices mostly rely on natural gravity or low pressure, resulting in slow ink flow rate and low filtration efficiency. This inefficient filtration method makes it difficult for the production line to maintain continuity and efficiency, increasing production costs and time. Due to the insufficient wear resistance and corrosion resistance of traditional mesh materials, particles accumulate and easily cause mesh clogging. This not only affects the filtering effect, but also greatly shortens the service life of the equipment and increases maintenance costs.

[0035] The present application provides an advanced mesh device, method and controller for pressurized ink filtration. The ink feed chamber is the starting point of the ink filtration process, and the ink to be filtered first flows into the chamber. The design of the feed chamber needs to ensure that the ink can enter the system evenly to reduce the problems of bubbles and uneven flow. The pressurization chamber is connected to the ink feed chamber, and the ink flows from the feed chamber into the pressurization chamber. The main function of the pressurization chamber is to pressurize the ink under a certain pressure to increase the flow rate and filtration efficiency of the ink.

[0058] In the process of photovoltaic glass screen printing, the quality of ink plays a vital role in the pattern clarity and consistency of the final product. However, the existing technology has many shortcomings in removing large particle impurities in the ink. Traditional filtering devices usually use filter mesh made of a single material with a large pore size, which makes it difficult to effectively intercept larger particle impurities in the ink. These unfiltered particles are easy to clog the screen during the screen printing process, causing pattern defects and even equipment failure. At the same time, when processing high-viscosity inks, existing devices mostly rely on natural gravity or low pressure, resulting in slow ink flow rate and low filtration efficiency. This inefficient filtration method makes it difficult for the production line to maintain continuity and efficiency, increasing production costs and time. Due to the insufficient wear resistance and corrosion resistance of traditional mesh materials, particles accumulate and easily cause mesh clogging. This not only affects the filtering effect, but also greatly shortens the service life of the equipment and increases maintenance costs.

[0059] Therefore, there is an urgent need for an advanced mesh device for pressurized ink filtering to solve at least one of the above problems.

[0060] To solve the above problems, please refer to Figures 1 to 3 The present application provides an advanced mesh device for pressurized filtering of ink, comprising: an ink feed chamber 13, into which the ink to be filtered flows; a pressurizing chamber 6, which is connected to the ink feed chamber 13 so that the ink in the ink feed chamber 13 flows into the pressurizing chamber 6; a pressurizing module, which comprises a transmission assembly and a pressurizing plate 7, wherein the pressurizing plate 7 is arranged on the pressurizing chamber 6, and the transmission assembly is connected to the pressurizing plate 7 to control the up and down movement of the pressurizing plate 7. The ink in the pressurized chamber 6 is pressurized when the pressurized plate 7 moves up and down; the mesh module 10 is arranged at the bottom of the pressurized chamber 6, and is used to intercept large particles of impurities in the ink to complete the filtering of the ink; wherein the frame size and mesh aperture of the mesh module 10 are determined according to the filtering requirements corresponding to the ink; the controller 2 is electrically connected to the transmission component, and is used to control the transmission component to drive the pressurized plate 7 to move up and down, and pressurize the ink in the pressurized chamber 6.

[0061] Specifically, in order to solve the problems of low ink filtration efficiency, unclear patterns, frequent equipment failures, and high maintenance costs in the photovoltaic glass screen printing process, this application provides an advanced mesh device for pressurized ink filtration. The device mainly consists of the following parts:

[0062] Ink feed chamber 13: The ink to be filtered enters the system from here to ensure that the ink is in a stable state before pressurization.

[0063] The pressurizing chamber 6 is connected to the ink feeding chamber 13 and is used to transfer the ink in the feeding chamber to the pressurizing chamber 6 .

[0064] Pressurizing module: includes a transmission assembly and a pressurizing plate 7. The pressurizing plate 7 is arranged above the pressurizing chamber 6, and the transmission assembly is connected to the pressurizing plate 7. The up and down movement of the pressurizing plate 7 is controlled by the controller 2 to pressurize the ink in the pressurizing chamber 6.

[0065] The mesh module 10 is arranged at the bottom of the pressurized chamber 6 to intercept large particles of impurities in the ink and filter the ink. The frame size and mesh aperture of the mesh module 10 are customized according to the filtering requirements of the ink.

[0066] Controller 2 : electrically connected to the transmission assembly, used to accurately control the movement of the pressurizing plate 7 , thereby achieving effective pressurization of the ink in the pressurizing chamber 6 .

[0067] Among them, the ink feed chamber 13 is similar to an ink storage tank, and a stirring device is provided inside to ensure that the ink is evenly distributed. The pressurized chamber 6 is a closed container, which is connected to the ink feed chamber 13 through a pipeline, and a valve is provided on the pipeline to control the inflow of ink. The transmission component can be a cylinder, a hydraulic cylinder or an electric push rod, which is used to drive the pressurized plate 7 to move up and down. The pressurized plate 7 is a movable flat plate, which is connected to the transmission component and can move up and down in the pressurized chamber 6 to pressurize the ink. The frame size and mesh aperture of the mesh module 10 are designed according to the viscosity and particle size of the ink, and the mesh material can be selected from corrosion-resistant and wear-resistant materials, such as stainless steel or polytetrafluoroethylene (PTFE). The controller 2 can be a PLC (programmable logic controller 2) or a microprocessor (MCU), which monitors the pressure in the pressurized chamber 6 and the flow rate of the ink through sensors, thereby realizing precise control of the pressurized plate 7.

[0068] In the corresponding working process of the device, feeding stage: the ink to be filtered enters the ink feeding chamber 13 through the pipeline, and the stirring device in the feeding chamber ensures that the ink is evenly distributed. Pressurization stage: the valve is opened, and the ink flows into the pressurization chamber 6 through the pipeline. The controller 2 starts the transmission assembly and drives the pressurization plate 7 to move downward to pressurize the ink in the pressurization chamber 6. Filtration stage: the pressurized ink passes through the mesh module 10, and the mesh intercepts large particles of impurities in the ink to complete the filtration. Discharge stage: the filtered ink is discharged from the bottom of the pressurization chamber 6 and enters the next production link. The pressurization plate 7 rises to prepare for the next feeding and pressurization.

[0069] Through the pressurization method, the ink flow rate is significantly accelerated, the filtration efficiency is improved, and the production line can maintain continuity and efficiency. The aperture of the mesh module 10 can be customized according to the particle size of the ink, effectively intercepting large particle impurities and ensuring the purity of the ink. The use of corrosion-resistant and wear-resistant mesh materials reduces the blockage problem caused by particle accumulation, extends the service life of the equipment, and reduces maintenance costs. Large particle impurities are intercepted to avoid screen blockage during silk screen printing, thereby reducing pattern defects and improving product quality and consistency. The pressurization method allows high-viscosity inks to pass through the mesh quickly, solving the problem that traditional filtering devices are difficult to handle high-viscosity inks. The controller 2 can accurately control the movement of the pressure plate 7 to ensure the stability and consistency of the pressurization process and reduce errors in human operation.

[0070] In summary, this advanced mesh device for pressurized ink filtration significantly improves the filtration efficiency and quality of the ink through the pressurization method and the customized mesh module 10, solves the shortcomings of traditional filtration devices in handling high-viscosity inks and intercepting large particle impurities, and provides a more reliable and efficient solution for photovoltaic glass screen printing production lines.

[0071] In some embodiments, it further includes: an ink collector 12 , which is disposed toward the bottom of the pressurized chamber 6 , and the ink filtered by the mesh module 10 flows into the ink collector 12 .

[0072] The ink collector 12 is arranged toward the bottom of the pressurized chamber 6 and is used to collect the filtered ink. The ink collector 12 can be a closed container connected to the bottom of the pressurized chamber 6 through a pipe to ensure that the filtered ink flows smoothly into the collector. The ink collector 12 is arranged below the bottom of the pressurized chamber 6 and is connected to the bottom of the pressurized chamber 6 through a pipe. The ink collector 12 can be a closed container with a sensor for monitoring the collection of ink.

[0073] The filtered ink flows from the bottom of the pressurizing chamber 6 through a pipe into the ink collector 12. The pressurizing plate 7 rises to prepare for the next feeding and pressurization. The ink collector 12 collects the filtered ink and monitors the collection of the ink through a sensor to ensure the smooth progress of the collection process.

[0074] The ink collector 12 can ensure that the filtered ink is completely collected, avoid ink waste, and improve ink utilization. The ink collector 12 collects the filtered ink in a centralized manner, avoids ink scattering or leakage during the filtering process, and reduces environmental pollution. The ink collector 12 can be used in conjunction with the controller 2 to monitor the collection of ink through sensors, achieve automatic control, and reduce errors and labor intensity in manual operations. The ink in the collector can be directly transported to the next production link, which is convenient for subsequent processing and use, and improves production efficiency. The design of the ink collector 12 reduces ink leakage and contamination during the filtering process, extends the service life of the equipment, and reduces maintenance costs. Through the ink collector 12, the production line can operate more efficiently, reduce production interruptions caused by ink leakage or incomplete collection, and improve production continuity.

[0075] In summary, the advanced mesh device for pressurized ink filtering is further improved by adding the ink collector 12. This improvement not only improves the utilization rate of ink and reduces pollution, but also improves the automation and production efficiency of the entire device, providing a more reliable and efficient solution for the photovoltaic glass screen printing production line.

[0076] Exemplarily, it also includes: a guide plate 11, which is arranged between the ink collector 12 and the mesh module 10, and is used to guide the filtered ink to smoothly enter the collector to avoid secondary contamination of the ink.

[0077] By adding the design of the guide plate 11, the advanced mesh device for pressurized ink filtering is further optimized. This improvement not only avoids secondary contamination of the filtered ink when it enters the collector, improves the purity and quality of the ink, but also reduces equipment failures and maintenance costs, and improves the production efficiency and reliability of the entire device. This provides a more complete solution for photovoltaic glass screen printing production lines.

[0078] In some embodiments, the transmission assembly includes: a first transmission rod 3, the setting direction of the first transmission rod 3 is perpendicular to the movement direction of the pressurized chamber 6; a second transmission rod 4, the second transmission rod 4 is connected to the pressurized plate 7 and the first transmission rod 3, and the setting direction of the second transmission rod 4 is parallel to the movement direction of the pressurized chamber 6; wherein the controller 2 is electrically connected to the first transmission rod 3, and is used to control the horizontal movement of the first transmission rod 3 (such as by controlling Figure 1 The motor 1 in the embodiment controls the horizontal movement of the first transmission rod 3 and drives the vertical movement of the second transmission rod 4 and the pressure plate 7 (such as by Figure 1 The gear transmission member 5 in the pressurizing chamber 6 is driven to pressurize the ink in the pressurizing chamber 6.

[0079] The first transmission rod 3 is set in a direction perpendicular to the movement direction of the pressurized chamber 6, that is, it is set horizontally. The second transmission rod 4 is connected to the pressurized plate 7 and the first transmission rod 3, and is set in a direction parallel to the movement direction of the pressurized chamber 6, that is, it is set vertically. The pressurized plate 7 is set above the pressurized chamber 6, and is connected to the first transmission rod 3 through the second transmission rod 4. It can move up and down in the pressurized chamber 6 to pressurize the ink. The controller 2 is electrically connected to the first transmission rod 3, and is used to control the horizontal movement of the first transmission rod 3, thereby driving the up and down movement of the second transmission rod 4 and the pressurized plate 7 to achieve pressurization of the ink in the pressurized chamber 6.

[0080] In the pressurization stage, the valve is opened, and the ink flows into the pressurization chamber 6 through the pipeline. The controller 2 starts the first transmission rod 3 to move horizontally. The horizontal movement of the first transmission rod 3 drives the second transmission rod 4 to move up and down, thereby controlling the up and down movement of the pressurization plate 7. When the pressurization plate 7 moves downward, the ink in the pressurization chamber 6 is pressurized.

[0081] Through the cooperation of the first transmission rod 3 and the second transmission rod 4, the controller 2 can more accurately control the up and down movement of the pressure plate 7 to ensure the stability and consistency of the pressure process. The horizontal movement of the first transmission rod 3 can more effectively drive the up and down movement of the second transmission rod 4 and the pressure plate 7, thereby improving the efficiency and speed of the pressure. The design of the transmission assembly for horizontal and vertical movement reduces the wear of mechanical parts and prolongs the service life of the equipment. The design of this transmission assembly can flexibly adjust the range and speed of movement of the pressure plate 7 to adapt to inks of different viscosities and particle sizes, thereby improving the versatility and adaptability of the device. Accurate pressure control and efficient transmission design enable the production line to operate more continuously and efficiently, reducing production interruptions caused by uneven pressure or mechanical failures. Reducing mechanical wear and increasing equipment life reduces maintenance costs and downtime. The design of this transmission assembly is easy to integrate with the automation control system to achieve full automation control and reduce errors and labor intensity in manual operation.

[0082] In summary, the pressurization efficiency and stability of the advanced mesh device for pressurized ink filtration are further improved by the detailed design of the cooperation between the first transmission rod 3 and the second transmission rod 4. This design not only meets the filtering needs of various inks, but also reduces mechanical wear, prolongs the service life of the equipment, improves production continuity and efficiency, and provides a more reliable and efficient solution for photovoltaic glass screen printing production lines.

[0084] The pressure detection module 8 is installed on the pressurizing plate 7 and is used to detect the real-time pressure of the pressurizing chamber 6 in real time. The pressure detection module 8 can be a pressure sensor or a pressure transmitter. The controller 2 is electrically connected to the first transmission rod 3 and the pressure detection module 8, and is used to obtain the ink characteristics and generate pressurization parameters according to the real-time pressure to control the operation of the transmission component. In the pressurization stage, the valve is opened, and the ink flows into the pressurizing chamber 6 through the pipeline. The controller 2 starts the first transmission rod 3 to make it move horizontally. The horizontal movement of the first transmission rod 3 drives the second transmission rod 4 to move up and down, thereby controlling the up and down movement of the pressurizing plate 7. The pressure detection module 8 detects the pressure in the pressurizing chamber 6 in real time and feeds the data back to the controller 2. The controller 2 obtains the characteristics of the ink, such as ink viscosity, etc. According to the ink characteristics and the real-time pressure, the controller 2 generates corresponding pressurization parameters, such as pressurization rate and pressurization pressure. The controller 2 dynamically adjusts the movement of the first transmission rod 3 and the second transmission rod 4 according to the generated pressurization parameters to ensure the stability and efficiency of the pressurization process.

[0085] The pressure detection module 8 can detect the pressure in the pressurization chamber 6 in real time to ensure the stability and controllability of the pressurization process. The controller 2 generates pressurization parameters according to the ink characteristics (such as viscosity) and the real-time pressure, and dynamically adjusts the operation of the transmission component to improve the accuracy and efficiency of pressurization. By dynamically adjusting the pressurization parameters, the uniformity and stability of the ink during the filtration process are ensured, thereby improving the filtration effect and reducing the leakage of impurities.

The feed control pipeline 14 connects the ink feed chamber 13 and the pressurizing chamber 6. The flow sensor detects the flow speed of the ink in real time and feeds the data back to the controller 2.

Accurately controlling the feed amount can avoid too much or too little ink in the pressurized chamber 6, ensure the consistency and stability of the pressurization and filtration process, and thus improve the filtration effect. By accurately controlling the feed amount, the pressure mutation in the pressurized chamber 6 is avoided, and the equipment failure and wear caused by uneven feed are reduced. Combined with the feed control pipeline 14 and the flow sensor, the controller 2 can dynamically adjust the feed speed according to the characteristics of different inks (such as viscosity), adapt to the filtration requirements of various inks, and improve the versatility and flexibility of the device. By adjusting the feed speed in real time, it is ensured that the amount of ink in the pressurized chamber 6 is always in the best state, which improves production efficiency and continuity. Accurately controlling the feed amount can avoid unnecessary pressurization operations, reduce energy consumption, and improve energy utilization efficiency. The automatic adjustment function of the controller 2 reduces the need for manual operation, reduces the difficulty of operation and operation errors.

[0112] The present application provides an advanced mesh device for pressurized ink filtration, wherein the ink feed chamber is the starting point of the ink filtration process, and the ink to be filtered first flows into the chamber. The design of the feed chamber needs to ensure that the ink can enter the system evenly and reduce the problems of bubbles and uneven flow. The pressurization chamber is connected to the ink feed chamber, and the ink flows from the feed chamber into the pressurization chamber. The main function of the pressurization chamber is to pressurize the ink under a certain pressure to increase the flow rate and filtration efficiency of the ink. The transmission assembly is responsible for driving the up and down movement of the pressurization plate. Pneumatic, hydraulic or electric drive modes can be selected, depending on the application scenario and equipment requirements. The pressurization plate is arranged at the upper part of the pressurization chamber and connected to the transmission assembly, and pressure is applied to the ink in the pressurization chamber by up and down movement. The design of the pressurization plate needs to ensure that it moves smoothly to avoid unnecessary shear force on the ink.

At the same time, the up and down movement of the pressure plate can regularly remove the particle accumulation on the mesh and extend the service life of the mesh.

[0115] 3. Improve product quality: Since large particles of impurities are effectively intercepted, the filtered ink is purer, which can reduce pattern defects during the screen printing process and improve the quality and consistency of the final product.

[0116] 4. Automated control: The introduction of the controller enables the entire filtration process to be automated, reducing the need for manual operation. The controller can monitor the flow rate and pressure of the ink through sensors, and adjust the movement of the pressure plate in real time to ensure the stability of the filtration process.

[0120] See also Figure 4 , Figure 4 This is a schematic flow chart of a method for pressurized ink filtering provided by an embodiment of the present application. The method for pressurized ink filtering can be implemented by a controller of a system provided by any embodiment of the present application, and the controller can be a microcontroller unit (MCU).

[0121] Specifically, Figure 4 As shown, the provided method for pressurized ink filtering includes steps S101 to S103. The details are as follows:

[0122] Step S101: Acquire the characteristics of the ink to be filtered and the real-time pressure of the pressurizing chamber.

[0123] Specifically, the characteristics of the ink to be filtered are obtained through sensors or preset parameters, mainly including the viscosity of the ink. It can also include the temperature and density of the ink, which will also affect the flow and filtering effect of the ink. The pressure inside and outside the pressurized chamber is detected in real time by the pressure detection module installed on the pressurized chamber and the mesh module. The real-time pressure data is transmitted to the controller through the signal line.

[0124] For example, viscosity sensors and temperature sensors are installed in the ink feed chamber and the pressurized chamber respectively, and the data is transmitted to the controller through the data line. Pressure sensors are installed at the top and bottom of the pressurized chamber to detect and transmit the pressure data to the controller in real time.

[0125] By acquiring ink characteristics and real-time pressure, accurate data support can be provided for subsequent steps to ensure accurate generation of pressurization parameters. Control parameters can be adjusted in real time to adapt to changes in the characteristics of different inks and improve the flexibility of the system. By monitoring pressure in real time, pressure anomalies can be discovered and handled in a timely manner to avoid equipment failures caused by excessive pressure. By accurately acquiring ink characteristics, high efficiency and stability in the filtration process can be ensured.

[0126] Step S102: Generate pressurization parameters corresponding to the transmission component according to the ink characteristics and the real-time pressure; the ink characteristics at least include ink viscosity, and the pressurization parameters at least include pressurization rate and pressurization pressure.

[0127] Specifically, the main parameter of the ink characteristics is the viscosity of the ink. Other parameters may also include the temperature and density of the ink. The main parameter of the real-time pressure is the pressure difference between the inside and outside of the pressurization chamber. The pressurization parameters include calculating the appropriate pressurization rate according to the ink characteristics and the real-time pressure. Calculating the appropriate pressurization pressure according to the ink characteristics and the real-time pressure. The controller calculates the appropriate pressurization parameters according to the ink characteristics and the real-time pressure through a preset algorithm or formula.

[0128] For example, the controller uses a pre-stored algorithm to generate pressurization parameters based on the viscosity of the ink and the real-time pressure. For example, a proportional integral derivative (PID) control algorithm can be used to dynamically adjust the pressurization rate and pressurization pressure based on real-time pressure changes.

[0129] By dynamically generating pressurization parameters according to ink characteristics and real-time pressure, the stability and efficiency of the pressurization process are ensured. By calculating the pressurization parameters through algorithms or formulas, precise control can be achieved to improve the filtering effect. It can adapt to different ink characteristics and production conditions, and improve the versatility and flexibility of the system. By optimizing the pressurization parameters, ink waste can be reduced and resource utilization can be improved. Ensure that the pressurization process is carried out under the optimal parameters to improve production efficiency and quality.

[0130] Step S103. Control the transmission component to work according to the pressurization parameters, so as to control the transmission component to drive the pressurization plate to move up and down, pressurize the ink in the pressurization chamber, and the pressurized ink is filtered out through the mesh module to complete the filtering of the ink.

[0131] Specifically, the controller controls the movement of the transmission assembly through electrical signals. The pressure plate is arranged above the pressure chamber. The ink in the pressure chamber is pressurized by moving up and down. Mesh module: ensures the filtering effect. During the pressurization process, the pressure plate moves up and down to pressurize the ink in the pressure chamber so that it passes through the mesh module. The flow sensor and pressure sensor installed on the mesh module monitor the filtering effect and pressure changes in real time to ensure the stability and efficiency of the filtering process.

[0132] By precisely controlling the movement of the pressurizing plate, the efficiency and stability of the pressurization process are ensured, and the filtering effect is improved. The circular frame structure and the evenly distributed mesh aperture can ensure the uniform distribution of the ink on the mesh, reduce the edge effect, and improve the filtering effect. The detachable connection design between the mesh module and the bottom of the pressurization chamber makes maintenance and replacement simpler and faster, reducing maintenance costs and time. Combined with the real-time monitoring and dynamic adjustment of steps S101 and S102, the pressurization process is ensured to be carried out within a safe range to avoid safety accidents caused by excessive pressure. By precisely controlling the pressurization parameters and the mesh aperture, the quality of the filtered ink is ensured to meet the requirements, improving product quality and production efficiency. By optimizing the pressurization parameters and mesh design, the wear of the equipment is reduced and the service life of the equipment is extended.
