[0056] As the global demand for renewable energy continues to grow, Building Integrated Photovoltaics (BIPV) technology has received widespread attention as a key technology for future low-carbon buildings. By integrating photovoltaic modules directly into the building structure, BIPV technology not only achieves the integration of building materials and photovoltaic power generation functions, but also has multiple advantages such as aesthetics and energy saving. Among them, high-temperature glazed colored glass, as the front panel of BIPV products, not only has good light transmittance and aesthetics, but also can effectively protect photovoltaic modules, and has broad market prospects. However, due to the huge size of architectural colored glaze glass, the corresponding silk screen printing screen also needs to be designed in a large format. This large-size screen faces the following challenges during use:

[0057] 1. Uneven tension: During the installation and use of large-size screens, the tension at the corners is too large and the tension at the center is insufficient, resulting in unstable printing effects.

[0058] 2. Deformation and sagging: Due to the weight of the screen frame and mesh, as well as the influence of factors such as temperature, humidity, and printing pressure, large screens are prone to deformation and sagging, affecting printing accuracy.

[0059] 3. Center of gravity shift: During long-term use and multi-station printing, the center of gravity of the screen may shift, further exacerbating the instability of the screen and affecting printing quality and production efficiency.

[0060] 4. Difficulty in manual adjustment: The traditional screen adjustment method relies on manual adjustment, which is not only time-consuming and labor-intensive, but also difficult to ensure accuracy, making it difficult to meet the needs of large-scale, high-precision production.

[0061] Therefore, there is an urgent need for a screen adjustment method for a photovoltaic module to solve at least one of the above problems.

[0062] To solve the above problems, please refer to Figure 1 and Figure 2 The embodiment of the present application provides a screen adjustment system, comprising a screen frame 1, wherein a screen printing area is formed in the screen frame 1, and a photovoltaic module 4 to be screen printed is placed in the screen adjustment area; a photosensitive adhesive 3, wherein the photosensitive adhesive 3 is arranged in the screen frame 1 surrounding the screen printing area;

[0063] A plurality of screen fixing devices 5, wherein the screen fixing devices 5 are arranged between the photosensitive adhesive 3 and the screen frame 1, and are used to fix the photosensitive adhesive 3 and the photovoltaic module 4 in the screen frame 1; the screen fixing devices 5 at least include a cushion block 5.1, a hydraulic regulator 5.2, a clamp 5.3 and a height sensor 5.4, wherein the cushion block 5.1, the hydraulic regulator 5.2 and the clamp 5.3 are arranged in a coordinated manner between the photosensitive adhesive 3 and the screen frame 1, and the height sensor 5.4 is used to measure the height information corresponding to the screen fixing device 5; a control device, wherein the control device and the hydraulic regulator 5 .2 is electrically connected to the height sensor 5.4, and is used to obtain the height information measured by each of the height sensors 5.4 and the position information set for each of the screen fixing devices 5; the control device also obtains the frame size information corresponding to the screen frame 1; the control device generates the height adjustment information corresponding to each of the screen fixing devices 5 according to the frame size information, the height information and the position information corresponding to each of the screen fixing devices 5, so as to adjust the height of the corresponding screen fixing device 5 according to the height adjustment information, so as to ensure that the center of gravity of the screen frame 1 remains stable during the silk-screen printing process of the photovoltaic module 4.

[0064] Specifically, the provided screen adjustment system is intended to solve the problems faced by large-size screens during the screen printing process of photovoltaic modules 4, including uneven tension, deformation and sagging, center of gravity offset and difficulty in manual adjustment. The system realizes automatic adjustment by integrating multiple screen fixing devices 5 and control equipment to ensure the stability and printing quality of the screen. The screen frame 1 is the main body of the screen, which has a screen printing area. The inner side of the frame is coated with photosensitive glue 3 for fixing the screen printing mesh. The photosensitive glue 3 is arranged in the screen frame 1 to surround the screen printing area, and is used to firmly fix the screen printing mesh in the screen frame 1. Multiple screen fixing devices 5 are arranged between the photosensitive glue 3 and the screen frame 1 for adjusting and fixing the screen.

[0065] like Figure 2As shown, each screen fixing device 5 includes a pad 5.1, a hydraulic regulator 5.2, a clamp 5.3 and a height sensor 5.4. Pad 5.1: used to support the screen to prevent it from sagging. The hydraulic regulator 5.2 adjusts the height of the pad 5.1 through the hydraulic control system, thereby adjusting the tension and position of the screen. The clamp 5.3 is used to fix the screen to ensure that it does not move during the silk screen printing process. The height sensor 5.4 is used to measure the height information corresponding to the screen fixing device 5 in real time and feed it back to the control device. The control device is electrically connected to the hydraulic regulator 5.2 and the height sensor 5.4, and is used to obtain height information and position information, and generate height adjustment instructions based on this information. According to the size information of the screen frame 1, the height information and position information of each screen fixing device 5, the height adjustment information is generated, and the height of the screen is automatically adjusted through the hydraulic regulator 5.2 to ensure the stability of the center of gravity of the screen.

[0066] Assume that a photovoltaic module 4 with a size of 2000mm x 3000mm is being printed, and the size of the screen frame 1 is 2200mm x 3200mm. The working process of the system is as follows:

[0067] Initial installation: Photosensitive adhesive 3 is coated inside the screen frame 1 to fix the screen printing mesh. Multiple screen fixing devices 5 are evenly distributed around the screen frame 1, each device includes a pad 5.1, a hydraulic regulator 5.2, a clamp 5.3 and a height sensor 5.4.

[0068] Height measurement: The height sensor 5.4 measures the height of the screen fixing device 5 in real time and transmits this data to the control device.

[0069] Position and size information acquisition: The control device acquires the position information of the screen fixing device 5 and the size information of the screen frame 1 .

[0070] Generate height adjustment information: The control device calculates the height that needs to be adjusted for each screen fixing device 5 according to the acquired height information, position information and screen frame 1 size information to ensure uniform tension and stable center of gravity of the screen.

[0071] Automatic adjustment: The control device sends the height adjustment information to the hydraulic regulator 5.2, which automatically adjusts the height of the pad 5.1, thereby adjusting the position of the screen. The clamp 5.3 ensures that the screen does not move during the adjustment process.

[0072] Printing process: During the entire printing process, the height sensor 5.4 continuously monitors the height changes of the screen, and the control device makes real-time adjustments based on these changes to ensure the stability of the screen and the printing quality.

[0073] By automatically adjusting the height of the pad 5.1, the tension of the screen at each position can be ensured to be uniform, avoiding the problem of excessive tension at the corners and insufficient tension at the center, and improving the stability and consistency of the printing effect. The support of the pad 5.1 and the fine adjustment of the hydraulic regulator 5.2 can effectively prevent the deformation and sagging of the screen due to factors such as its own weight, temperature, and humidity, and maintain the flatness and printing accuracy of the screen. The control device generates a height adjustment instruction based on the size information of the screen frame 1 and the height information of each fixture to ensure that the center of gravity of the screen is always stable and reduce printing quality problems caused by center of gravity offset.

[0074] The traditional manual adjustment method is not only time-consuming and labor-intensive, but also difficult to ensure accuracy. The automatic adjustment system can greatly reduce the adjustment time, improve production efficiency, and ensure the adjustment accuracy to meet the needs of large-scale, high-precision production. The automatic adjustment system reduces the reliance on manual labor, reduces the difficulty of operation, and improves the reliability and consistency of the system. The system can be flexibly adjusted according to different screen sizes and working conditions, has strong adaptability and versatility, and is suitable for screen printing production of photovoltaic modules of different specifications.

[0075] In some embodiments, there are four screen fixing devices 5 , which are respectively disposed at the four corners of the screen frame 1 , so as to ensure the stability of the four corners of the screen frame 1 by adjusting each of the screen fixing devices 5 .

[0076] Four screen fixing devices 5 are respectively arranged at the four corners of the screen frame 1. The pad 5.1 is used to support the corners of the screen to prevent sagging. The height of the pad 5.1 is adjusted by the hydraulic system to ensure the tension and position of the corners. The clamp 5.3 fixes the corners of the screen to prevent it from moving during the printing process. The height sensor 5.4 measures the height information of the corners of the screen in real time and feeds it back to the control device.

[0077] The control device obtains the height information measured by each height sensor 5.4 and the position information of the screen fixing device 5. The controller generates a height adjustment instruction corresponding to each screen fixing device 5 according to the information. The height adjustment information is sent to the hydraulic regulator 5.2 to adjust the height of the cushion block 5.1 to ensure the stability of the screen corners.

[0078] By concentrating four screen fixing devices 5 at the corners, the stability and uniform tension of the screen corners can be effectively ensured, avoiding the problem of excessive tension at the corners and insufficient tension at the center. Through fine adjustment of the hydraulic regulator 5.2, the deformation and sagging of the screen corners due to factors such as deadweight, temperature, and humidity can be reduced, and the overall flatness of the screen can be maintained. The stability of the screen corners is crucial to the printing quality, especially for large-sized photovoltaic modules 4. This embodiment improves the uniformity and consistency of the printing effect by ensuring the stability of the corners. The number of the four screen fixing devices 5 is small, and the adjustment process is relatively simple, which can be completed in a shorter time, thereby improving production efficiency.

[0079] For example, Figure 2 As shown, the screen frame 1 is made of aluminum profiles with a strength greater than a preset strength; the four corners of the screen frame 1 are reinforced rib structures 2 to reduce the stress of the edge mesh and prevent the mesh from sagging.

[0080] Aluminum profiles with strength greater than a preset value are selected to make the screen frame 1 to improve the rigidity and bearing capacity of the frame. Reinforcement rib structures 2 are designed at the four corners of the screen frame 1 to enhance the strength of the corners, reduce the stress of the edge mesh, and prevent the mesh from sagging. The reinforcement rib structure 2 is used in conjunction with the screen fixing device 5 (such as the fixing device in Example 1) to ensure the overall stability and uniform tension of the screen.

[0081] By using high-strength aluminum profiles to make the screen frame 1, the rigidity and bearing capacity of the frame can be significantly improved, and deformation caused by deadweight and external forces can be reduced. The introduction of the reinforcing rib structure 2 can effectively reduce the stress of the edge mesh, prevent the edge mesh from breaking or sagging due to stress concentration, and increase the service life of the screen. The enhancement of the frame rigidity and the reduction of the edge stress help to maintain the overall flatness and uniform tension of the screen, thereby improving the printing accuracy and quality.

[0082] For large-sized screens, the strength and rigidity of the frame are particularly important. This embodiment is particularly suitable for the use of large-sized screens through the optimization of materials and structures, ensuring its stability during long-term and multi-station printing. The reinforcing rib structure 2 can effectively prevent the mesh from being damaged due to stress concentration, extend the service life of the screen, and reduce the frequency and cost of replacing the screen. The stability and extended service life of the screen can reduce downtime and maintenance costs in the production process and improve overall production efficiency.

[0083] By using hydraulic regulators and clamps, the system can dynamically adjust the tension of the screen according to the height and position information of each point, ensuring uniform tension at the corners and center of the screen, thereby significantly improving the stability of the printing effect. The height sensor in the screen fixture can monitor the height change of the screen in real time. When the screen is deformed or drooped due to factors such as its own weight, temperature, humidity or printing pressure, the system will immediately adjust the corresponding height to restore the flatness of the screen and ensure printing accuracy. The control device can generate height adjustment information based on the size information of the screen frame and the height and position information of each screen fixture, so that the screen can maintain a stable center of gravity during long-term use and multi-station printing, preventing instability caused by center of gravity shift, thereby improving printing quality and production efficiency.

[0084] At the same time, the traditional manual adjustment method is not only time-consuming and labor-intensive, but also difficult to ensure the adjustment accuracy. The system automatically calculates and adjusts the height of the screen fixture through the control equipment to ensure the accuracy and consistency of each adjustment, meeting the needs of large-scale, high-precision production. The system has a high degree of automation, which reduces the labor intensity of operators, saves labor costs, and also reduces the errors caused by human operation. The height sensor monitors the height change of the screen in real time, and the control equipment can respond quickly to achieve closed-loop control, ensuring the immediacy and effectiveness of the screen adjustment. The system is not only suitable for large-size screens, but also can adapt to screens of different sizes and shapes, with high flexibility and versatility. By dynamically adjusting the screen tension and height, the deformation and wear of the screen are reduced, and the service life of the screen is extended.

[0085] In summary, the screen adjustment system effectively solves a series of problems in the use of large-size screens through automation and intelligent means, significantly improves the printing quality and production efficiency of photovoltaic modules, and reduces production costs and operating difficulties.

[0086] See also Figure 3 , Figure 3 1 is a schematic flow chart of a screen adjustment method for a photovoltaic module provided in an embodiment of the present application. The screen adjustment method for a photovoltaic module can be as follows: Figure 1 to Figure 2 According to any one of the embodiments of the present invention, the control device may be a micro control unit (MCU).

[0087] like Figure 3 As shown, the provided screen adjustment method for photovoltaic modules includes steps S101 to S104. The details are as follows:

[0088] Step S101: Acquire the height information measured by each height sensor and the position information of each screen fixing device.

[0089] Specifically, the height corresponding to the screen fixture is measured in real time by a height sensor, and the height information is transmitted to the control device. The specific position of each screen fixture in the screen frame is recorded, and the position information includes the coordinates of the fixture on the frame and the installation direction. Assume that there are four screen fixtures in the screen frame, located at four corners. The height sensor on each fixture measures the height in real time and transmits the data to the control device. At the same time, the control device records the coordinate position of each fixture, such as (0, 0), (2200, 0), (0, 3200), (2200, 3200). The height sensor can monitor the height change of the screen in real time to ensure that problems can be discovered and adjusted in time during the printing process. By obtaining the specific position information of each screen fixture, the control device can more accurately calculate and adjust the height of each fixture to ensure the overall stability of the screen.

[0090] Step S102: Obtaining frame size information corresponding to the screen frame.

[0091] Specifically, the size information of the screen frame, including width, height and thickness, is obtained by means of sensors or manual input. The size information of the screen frame is stored in the memory of the control device for subsequent calculation. Assume that the size of the screen frame is 2200mm x 3200mm and the thickness is 10mm. These size information is measured by sensors and stored in the memory of the control device. Obtaining the size information of the screen frame is the basis for height adjustment to ensure the accuracy of the calculation. Screen frames of different specifications can adapt to different photovoltaic modules, and the control device can be flexibly adjusted according to different size information.

[0092] Step S103: Generate height adjustment information corresponding to each screen fixing device according to the frame size information, the height information corresponding to each screen fixing device, and the position information.

[0093] Specifically, the control device performs data processing based on the acquired frame size information, the height information and the position information of each screen fixture. The height that needs to be adjusted for each screen fixture is calculated by an algorithm to generate height adjustment information. For example, the control device performs calculations based on the screen frame size (2200mm x 3200mm) and the height information of four screen fixtures (assuming that the initial heights are 10mm, 12mm, 11mm, and 13mm, respectively). After algorithm processing, height adjustment information is generated, for example, the heights of the four fixtures are adjusted to 12mm, 12mm, 12mm, and 12mm, respectively, to ensure that the tension of the screen frame is uniform and the center of gravity is stable. By calculating the height adjustment information of each fixture by an algorithm, the height of the screen can be adjusted more accurately to ensure uniform tension and stable center of gravity. The process of generating height adjustment information is automated, which reduces manual intervention and improves the reliability and consistency of the system.

[0094] Step S104: adjusting the height of the corresponding screen fixing device according to the height adjustment information to ensure that the center of gravity of the screen frame remains stable during the screen printing process of the photovoltaic module.

[0095] Specifically, the control device sends the generated height adjustment information to the hydraulic regulator of each screen fixing device. The hydraulic regulator adjusts the height of the pad according to the received instructions to ensure the stability of the center of gravity of the screen frame. For example, the control device sends the height adjustment information (12mm, 12mm, 12mm, 12mm) to the hydraulic regulators of four screen fixing devices. The hydraulic regulators adjust the height of the pads respectively and adjust the height of the four fixing devices to 12mm. During the printing process, the height sensor continuously monitors the height change of the screen. If it is found that the height is slightly drooping at a certain place, the control device will adjust the corresponding hydraulic regulator in time to ensure the stability of the screen. Through height adjustment, the center of gravity of the screen frame is ensured to remain at the set position to avoid printing quality problems caused by the center of gravity offset. The height adjustment process is automatically performed by the hydraulic regulator, which improves the adjustment speed and accuracy and reduces human errors. During the entire printing process, the height sensor continuously monitors the height change of the screen, and the control device adjusts in real time to ensure the stability of the screen and printing accuracy.

[0096] In summary, through the detailed description of the above four steps, it can be seen that the screen adjustment method can effectively solve the problems faced by large-size screens in the screen printing process, including uneven tension, deformation and sagging, center of gravity offset and difficulty in manual adjustment. The technical content and examples of each step show the specific implementation process of the method, and the beneficial effects highlight its advantages in improving printing quality and production efficiency. The combined use of these steps can ensure the stability and efficiency of the screen printing process of photovoltaic modules.

[0097] In some embodiments, the height adjustment information corresponding to each screen fixing device is generated based on the border size information, the height information and the position information corresponding to each screen fixing device, including: obtaining the number of devices and the weight of devices corresponding to the screen fixing device; generating the current coordinates corresponding to each screen fixing device based on the height information and the position information; generating the current center of gravity coordinates of the screen border based on the number of devices, the weight of the devices and the current coordinates; generating the target center of gravity coordinates corresponding to the screen based on the border size information and the height information; generating the height adjustment information corresponding to each screen fixing device based on the current center of gravity coordinates, the target center of gravity coordinates and the position information of each screen fixing device.

[0098] By determining the number of screen fixtures, for example four. Measure or obtain the weight of each screen fixture, including the pad, hydraulic regulator, clamp and height sensor. Obtain the height information measured by each height sensor. Record the specific position information of each screen fixture within the screen frame, such as coordinates. Combine the height information and position information to generate the current three-dimensional coordinates of each screen fixture. Calculate the current center of gravity coordinates of the screen frame through mathematical formulas using the number of devices, device weight and current coordinates. According to the size information of the screen frame and the expected height information, set an ideal target center of gravity coordinate to ensure the best stability of the screen during printing. According to the difference between the current center of gravity coordinate and the target center of gravity coordinate, as well as the position information of each screen fixture, calculate the height that needs to be adjusted for each screen fixture and generate height adjustment information.

[0099] By calculating the current center of gravity coordinates and the target center of gravity coordinates, the height of the screen fixture can be accurately adjusted to ensure that the center of gravity of the screen frame remains in the optimal position, thereby improving the stability and accuracy of printing. The stability of the center of gravity and the uniformity of tension are crucial to the printing quality. Embodiment A ensures uniform tension and stable center of gravity of the screen by finely adjusting the height of each screen fixture, thereby significantly improving the uniformity and consistency of the printing effect. The method can be flexibly adjusted according to different screen sizes and working conditions, has strong adaptability and versatility, and is suitable for screen printing production of photovoltaic modules of different specifications. The height sensor and control equipment can monitor and adjust the height of the screen in real time to ensure the continuous stability of the screen during the printing process and avoid printing quality problems caused by external factors (such as temperature and humidity changes). Through automated and precise height adjustment, the adjustment time and downtime are reduced, the overall production efficiency is improved, and the production needs of large quantities and high precision are met.

[0100] Exemplarily, the generating the current center of gravity coordinates of the screen frame according to the number of devices, the weight of devices and the current coordinates includes: obtaining the total weight corresponding to the screen frame; decomposing the current coordinates to obtain the first coordinate component in the x direction and the second coordinate component in the y direction; generating the current center of gravity coordinates of the screen frame according to the first coordinate component, the second coordinate component, the number of devices and the weight of devices; the expression of the current center of gravity coordinates includes:

[0101] ; ;

[0102] in, is the x-direction component corresponding to the current center of gravity coordinates, is the y-direction component corresponding to the current center of gravity coordinate; M is the total weight, is the number of devices, For the a first coordinate component corresponding to the screen fixing device, For the a second coordinate component corresponding to the screen fixing device, For the The weight of the device corresponding to each of the screen fixing devices.

[0103] The above formula can accurately calculate the current center of gravity coordinates of the screen frame, avoiding errors caused by human estimation and ensuring the accuracy of the calculation. The above example shows in detail how to calculate the current center of gravity coordinates of the screen frame based on the number of screen fixtures, the weight of the device and the current coordinates through specific calculation formulas and steps. Ensure that the center of gravity of the screen frame is kept in the best position during the screen printing process of large-size photovoltaic modules, thereby improving printing quality and production efficiency.

[0104] Exemplarily, the method of generating height adjustment information corresponding to each screen fixing device based on the current center of gravity coordinates, the target center of gravity coordinates and the position information of each screen fixing device includes: calculating the first offset coordinates corresponding to the current center of gravity coordinates and the target center of gravity coordinates; calculating the second offset coordinates of the current coordinates of the screen fixing device and the target center of gravity coordinates; and calculating the height adjustment information corresponding to each screen fixing device based on the first offset coordinates and the second offset coordinates.

[0105] By calculating the first offset coordinate and the second offset coordinate, the height of each screen fixture can be accurately adjusted to ensure that the center of gravity of the screen frame is stable at the target position. The calculation process of the height adjustment information is divided into two steps. First, the overall offset of the center of gravity is calculated, and then the local offset of each fixture is calculated to ensure the logic and accuracy of the calculation. This method can adapt to screen fixtures in different positions, has strong versatility and flexibility, and is suitable for a variety of working conditions. Through step-by-step calculation and local adjustment, the errors that may occur in the overall adjustment process are reduced, and the reliability and accuracy of the system are improved. The control device can monitor the height changes of the screen in real time, and adjust the height of the screen fixture in time according to the calculated height adjustment information to ensure the continuous stability of the printing process.

[0106] It should be noted that, in some embodiments, the height adjustment information corresponding to each of the screen fixing devices is calculated according to the first offset coordinate and the second offset coordinate, including: obtaining an adjustment coefficient corresponding to each of the screen fixing devices according to the size information of the screen frame and the position information of each of the screen fixing devices; the adjustment coefficient is used to confirm the influence of the center of gravity of the screen frame when the height of the screen fixing device is adjusted; the height adjustment information corresponding to each of the screen fixing devices is calculated according to the adjustment coefficient, the first offset coordinate, and the second offset coordinate; wherein the expression corresponding to the height adjustment information includes:

[0107] ;

[0108] in, For the height adjustment information corresponding to the screen fixing device, is the adjustment coefficient, is the x-direction component corresponding to the first offset coordinate, is the y-direction component corresponding to the first offset coordinate; For the an x-direction component of the second offset coordinate corresponding to the screen fixing device, For the The y direction component of the second offset coordinate corresponding to the screen fixing device.

[0109] By introducing the adjustment coefficient, the height adjustment of each fixture can be controlled more accurately to ensure that the center of gravity of the screen frame is stable at the target position. The adjustment coefficient can be dynamically adjusted according to the specific size of the screen frame and the position of the fixture to adapt to different working conditions and configurations. The introduction of the adjustment coefficient makes the calculation of height adjustment information more detailed, reduces the error caused by simple proportional adjustment, and improves the accuracy of the system. The calculation formula takes into account the offset of each fixture in the x-direction and y-direction, making the adjustment more scientific and reasonable, and avoiding excessive or insufficient adjustment.

[0110] It should be noted that, in some embodiments, the method of obtaining the adjustment coefficient corresponding to each screen fixing device based on the size information of the screen frame and the position information of each screen fixing device includes: placing the screen adjustment device on a preset adjustment device, wherein the height of each fixing device in the screen adjustment device is the same; obtaining the initial center of gravity coordinates corresponding to the screen frame based on the size information; adjusting the height of any one of the screen fixing devices multiple times to obtain multiple height adjustment amounts; obtaining the center of gravity change information corresponding to each height adjustment amount based on the position information corresponding to the screen fixing device corresponding to the height adjustment amount; and calculating the adjustment coefficient corresponding to the screen frame based on the multiple height adjustment amounts and the corresponding center of gravity change information using a linear regression method.

[0111] Through multiple experiments and linear regression methods, the adjustment coefficient of each screen fixture can be accurately calculated to ensure the accuracy of the adjustment. This method is based on actual data analysis and calculation, avoiding the subjectivity and error of human estimation, and improving the reliability and accuracy of the system. The method for obtaining the adjustment coefficient can be dynamically adjusted according to screen frames of different sizes and configurations, and has strong versatility and flexibility. Through the linear regression method, the impact of the height change of each fixture on the center of gravity of the screen frame can be scientifically analyzed, making the generation of height adjustment information more reasonable and scientific. Obtaining multiple adjustment coefficients at one time reduces the time for repeated adjustments and improves the efficiency and response speed of the system.

[0112] In some embodiments, adjusting the height of the corresponding screen fixing device according to the height adjustment information includes: acquiring silk screen environment information corresponding to the screen adjustment system; the silk screen environment information includes at least ambient temperature, ambient humidity and printing pressure; generating silk screen deformation information corresponding to the photovoltaic module according to the ambient temperature, ambient humidity and printing pressure; the silk screen deformation information includes droop information and center of gravity offset information; adjusting the height of the corresponding screen fixing device according to the droop information, center of gravity offset information and height adjustment information.

[0113] By considering the ambient temperature, ambient humidity and printing pressure, Example G can adapt to different screen printing environments, ensure that the height of the screen fixture can be accurately controlled under various conditions, and improve the environmental adaptability of the system. The introduction of droop information and center of gravity offset information can more comprehensively evaluate and adjust the height of the screen fixture, avoid errors caused by environmental factors, and improve the accuracy of adjustment. The screen printing environment information is acquired in real time, and the system can dynamically adjust the height of the screen fixture according to the current environmental conditions to ensure the continuous stability of the printing process. By accurately controlling the height of the screen fixture, printing quality problems caused by screen deformation or center of gravity offset can be reduced, thereby reducing the scrap rate and improving production efficiency.

[0114] The method of this embodiment can optimize the entire production process, make the screen printing operation more scientific and systematic, and help improve the overall production quality and efficiency.

[0115] By acquiring screen printing environment information (ambient temperature, ambient humidity and printing pressure), the screen printing deformation information (droop information and center of gravity offset information) of the photovoltaic module is generated, and combined with the initial height adjustment information, the height of each screen fixture is comprehensively adjusted. It can adapt to different screen printing environmental conditions to ensure the stability and reliability of the system. By comprehensively considering environmental factors and initial adjustment information, the accuracy of the height adjustment of the screen fixture is improved. Real-time acquisition of screen printing environment information enables the system to dynamically adjust during the production process to ensure the continuous stability of the printing process. In actual production, the center of gravity of the screen frame can be controlled more comprehensively and accurately to ensure the stability and printing quality of the screen under different screen printing environmental conditions, thereby improving overall production efficiency and quality.
