[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example:

[0042] like Figure 1 As shown, an embodiment of the present invention provides a high-precision color photovoltaic printing device nozzle alignment calibration system, comprising:

[0043] A high-precision camera is installed near the nozzle of the printing device to capture the position and status information of the nozzle orifice in real time. The high-precision camera has the characteristics of high resolution, high frame rate, low latency and low distortion;

[0044] A high-performance image processor, which is used to receive the image data transmitted by the high-precision camera, and perform preprocessing, feature extraction and image analysis to identify the position and status information of the nozzle orifice, and the high-performance image processor adopts an advanced image processing algorithm;

[0045] An intelligent calibration algorithm module, which calculates the position and angle of the nozzle that needs to be adjusted through an intelligent algorithm based on the nozzle nozzle position and status information extracted by the high-performance image processor, combined with preset calibration parameters and tolerance range, and supports static calibration, dynamic calibration and real-time calibration modes;

[0046] The precision mechanical adjustment mechanism realizes precise adjustment of the up and down, left and right and angle of the nozzle through the precision mechanical components of the servo motor, transmission mechanism and positioning device according to the calculation results of the intelligent calibration algorithm module.

[0047] Secondly, if Figure 2 As shown, the specific implementation method of the high-precision color photovoltaic printing equipment nozzle alignment calibration system includes the following steps:

[0048] Step 1: System installation and initialization:

[0049] (1) Install the high-precision camera at a suitable location near the nozzle of the printing device to ensure that its field of view can completely cover the nozzle orifice area. After the camera is installed, debug it to ensure that it can stably display the characteristics of high resolution, high frame rate, low latency and low distortion;

[0050] (2) Install a high-performance image processor and establish a stable data transmission connection between it and the high-precision camera. Ensure that the image processor can smoothly receive the image data from the camera. At the same time, load advanced image processing algorithms into the image processor;

[0051] (3) Install the intelligent calibration algorithm module and connect it to a high-performance image processor so that it can obtain the nozzle nozzle position and status information. Configure the intelligent calibration algorithm module, set the preset calibration parameters and tolerance range, and ensure that its static calibration, dynamic calibration, and real-time calibration modes can operate normally.

[0052] (4) Install precision mechanical adjustment mechanisms to ensure that precision mechanical components such as servo motors, transmission mechanisms, and positioning devices are accurately installed and firmly connected. Debug precision mechanical adjustment mechanisms to ensure that they have high response speed, high precision, and high reliability;

[0053] (5) Start the system for initial calibration. Start the high-precision camera and high-performance image processor to capture the initial position image of the nozzle orifice. The high-performance image processor preprocesses and extracts features from the initial position image and passes the position information of the nozzle orifice to the intelligent calibration algorithm module. The intelligent calibration algorithm module calculates the position and angle of the nozzle that needs to be adjusted based on this information and preset parameters. The precision mechanical adjustment mechanism accurately adjusts the nozzle according to the calculation results and continues to adjust until the preset tolerance requirements are met.

[0054] Step 2: Real-time calibration during printing:

[0055] (1) After the printing device starts working, the high-precision camera captures the image of the nozzle nozzle position in real time and immediately transmits the image data to the high-performance image processor;

[0056] (2) The high-performance image processor quickly pre-processes and extracts features from the real-time position image, accurately identifies the position information of the nozzle orifice, and sends it to the intelligent calibration algorithm module;

[0057] (3) The intelligent calibration algorithm module calculates the nozzle position and angle deviation in real time based on the real-time nozzle nozzle orifice position information;

[0058] (4) The precision mechanical adjustment mechanism quickly fine-tunes the printhead based on the calculation results of the intelligent calibration algorithm module to ensure that the printhead always maintains high-precision alignment throughout the entire printing process.

[0059] Step 3: Calibration data recording and analysis:

[0060] (1) During each calibration process, whether it is initial calibration or real-time calibration, the system records the calibration raw data, processing results and calibration effects. These data are stored in a dedicated storage area;

[0061] (2) Regularly start the data analysis function to evaluate and analyze the stored data related to the printhead status, calibration effect, and equipment performance. For example, analyze the trend of the printhead nozzle position deviation, the impact of the calibration effect on the print quality, etc.;

[0062] (3) Based on the data analysis results, targeted optimization and improvement are carried out on system parameters (such as calibration parameters, tolerance range, etc.), calibration algorithms (such as the calculation logic in the intelligent calibration algorithm module), and mechanical adjustment mechanisms (such as the control parameters of the servo motor, etc.) to continuously improve system performance.

[0063] Step 4: Implementation of the combined method of visual recognition and image processing:

[0064] A high-precision camera is used to capture the position and status of the nozzle orifice in real time. A high-performance image processor continuously receives image data and pre-processes the captured image through the loaded advanced image processing algorithm, including but not limited to denoising, contrast enhancement and other operations. Feature extraction is then performed to accurately identify the key feature points of the nozzle orifice, thereby achieving real-time capture and analysis of the nozzle orifice position and status, providing accurate data support for subsequent calibration work.

[0065] Step 5: Smart calibration algorithm implementation:

[0066] The intelligent calibration algorithm performs calculations based on the nozzle orifice position information, preset calibration parameters and tolerance range, and specific calculation logic. For example, by comparing the coordinate difference and angle difference between the actual nozzle position and the ideal position, combined with the nozzle motion model and equipment structure parameters, the position and angle of the nozzle that needs to be adjusted are calculated. In different calibration modes (static, dynamic, real-time), the algorithm accurately calculates the adjustment amount based on the corresponding conditions and input data.

[0067] Step 6: Design and implementation of precision mechanical adjustment mechanism:

[0068] The servo motor of the precision mechanical adjustment mechanism receives the control signal from the intelligent calibration algorithm module, and converts the motor's rotational motion into linear motion or angle adjustment of the nozzle through the transmission mechanism (such as high-precision screw, synchronous belt, etc.). The positioning device (such as high-precision linear guide, angle encoder, etc.) accurately controls the movement distance and angle of the nozzle to ensure the accuracy and reliability of the nozzle alignment. During the whole process, various precision mechanical components work together to ensure the high accuracy of nozzle adjustment.

[0069] Step 7: Real-time calibration mechanism implementation:

[0070] During the printing process, the high-precision camera continuously captures the nozzle orifice position information, and the intelligent calibration algorithm processes this information in real time to calculate the nozzle position and angle deviation. The precision mechanical adjustment mechanism quickly and accurately adjusts the nozzle according to the real-time deviation information. All links work closely together to ensure the stable operation of the real-time calibration mechanism and the high-precision alignment of the nozzle during the printing process, thereby ensuring the printing quality.

[0071] Step 8: Implementation of calibration data recording and analysis system:

[0072] The calibration data recording and analysis system records the calibration data (such as the original image data collected by the camera, the intermediate data processed by the image processor, the input and output data of the intelligent calibration algorithm, etc.) and results (the position and angle data before and after the nozzle adjustment, whether the calibration is successful, etc.) in detail each time a calibration event is triggered. In the analysis stage, the nozzle status (such as the nozzle hole wear can be inferred through long-term position changes), calibration effect (such as the improvement of printing quality after calibration) and equipment performance (such as the change in the response time of the precision mechanical adjustment mechanism) are evaluated through specific data analysis algorithms and models. Based on the evaluation results, the system automatically optimizes the relevant parameters and improves the equipment with manual intervention.

[0073] Step 9: System overall architecture and workflow assurance:

[0074] During the operation of the entire system, each module interacts with each other through standard data interfaces and communication protocols. For example, the camera and the image processor transmit image data through a high-speed data transmission line, and the image processor and the intelligent calibration algorithm module transmit processed nozzle information through a data interface in a specific format. Each module works in an orderly manner according to the established workflow, from image capture, processing, calibration calculation to nozzle adjustment, to ensure the efficient operation and stability of the system. At the same time, a monitoring and feedback mechanism is set up to promptly discover and handle problems that arise in the interaction between modules to ensure the stability of the overall system architecture.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
