[0001] The present invention relates to the field of printing technology, and more specifically, to a method for adjusting ink droplets, an ink droplet observation device, a device and a storage medium. Background Art

[0002] Inkjet printing technology occupies an important position in the field of digital printing and is widely used in many fields such as industrial manufacturing, advertising spraying, and office printing. The key to inkjet printing quality lies in the precise control of parameters such as the ejection speed, size, and shape of ink droplets. However, in the prior art, there are many problems with ink droplet observation and adjustment devices, which seriously restrict the improvement of printing quality.

[0003] First, traditional ink droplet observation devices usually have complex structures, and the setup and debugging processes are cumbersome, requiring professional technicians to operate, increasing the usage cost and time cost. Second, these devices lack intelligent image analysis functions and cannot accurately identify key parameters such as the shape, size, and speed of ink droplets in real time, resulting in inaccurate evaluation of ink droplet states and affecting the stability of printing quality. In addition, existing devices have poor adaptability when observing ink droplets of different inks or in different environments, and cannot flexibly adjust observation parameters, making it difficult to meet diverse printing requirements. Finally, the data storage and analysis capabilities are insufficient, and historical data cannot be effectively utilized for ink droplet state prediction and printing parameter optimization, further restricting the improvement of printing quality.

[0004] Therefore, the prior art has problems such as complex and difficult-to-adjust devices, inaccurate image analysis, poor adaptability, and insufficient data utilization. Summary of the Invention

[0005] In order to overcome the problems in the prior art such as complex and difficult-to-adjust devices, inaccurate image analysis, poor adaptability, and insufficient data utilization, the present invention designs an ink droplet adjustment method, an ink droplet observation device, a device and a storage medium that can effectively solve the above technical problems.

[0019] An ink droplet adjustment method includes the following steps:

[0020] The host computer sends a flash spraying instruction to the system board; after receiving the flash spraying instruction, the system board controls the nozzle to spray ink and simultaneously controls the exposure lamp group to flash; the camera captures the state information of the ink droplets at the nozzle position according to the flashing state of the exposure lamp group, including the position, size and roundness of the ink droplets, and transmits the captured ink droplet information to the system board, and the system board then sends the processed ink droplet information to the host computer for display.

[0021] By setting different flashing times of the exposure lamp group, the position information of the ink droplets is captured twice; the host computer calculates the spraying speed of the ink droplets during this time period according to the distance between the positions of the ink droplets captured twice and the corresponding time interval.

[0030] To better illustrate this embodiment, some components in the drawings will be omitted, enlarged or reduced, which does not represent the size of the actual product;

[0031] For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0032] The following will further illustrate the technical solutions of the present invention in conjunction with the drawings and embodiments.

[0033] Embodiment 1

[0034] An ink droplet observation device, as Figure 1 shown, includes:

[0035] A nozzle for ejecting ink droplets;

[0036] An exposure lamp group arranged on one side of the nozzle for providing illumination for ink droplet observation;

[0037] A camera arranged on the other side of the nozzle for capturing ink droplet images to obtain ink droplet-related information;

[0038] A system board card respectively connected to the nozzle, the exposure lamp group and the camera, for receiving instructions from the host computer, controlling the nozzle to eject ink and the exposure lamp group to flash, and processing the ink droplet image information collected by the camera;

[0039] A host computer for sending instructions to the system board card and receiving and displaying the ink droplet image information processed by the system board card, so that the user can adjust the printing parameters based on the information.

[0040] The nozzle uses a special nozzle for high-precision inkjet printers, which can eject ink droplets with a diameter between 10 and 50 microns according to the instructions of the system board. The ink is a specially formulated pigment ink, suitable for a variety of printing materials.

[0041] The exposure lamp group is located on one side of the nozzle and consists of multiple groups of multi-spectral LED lights, which can emit light of different spectra. According to the characteristics of the ink droplets and the observation requirements, the system board can control its spectral combination and brightness. For example, when observing the fine internal structure of the ink droplets, it can be adjusted to a combination of blue light and ultraviolet light to enhance the contrast of the internal structure of the ink droplets.

[0042] The camera is placed on the other side of the nozzle and is an MV-GE134GM-T-CL type high-speed, high-resolution intelligent focusing camera equipped with a DHO7-4.5 capture lens. This camera has an automatic focusing function. During the ink droplet ejection process, it can quickly adjust the focus point according to the movement state and position change of the ink droplets in real time to ensure that the ink droplets can be clearly captured at different ejection speeds, such as 1-10 m / s. Its resolution is as high as 13 million pixels, and the frame rate is 120 fps, which can capture the subtle morphological changes of the ink droplets.

[0043] The system board is connected to the nozzle, the exposure lamp group and the camera through high-speed data lines. It is the core control and processing unit of the entire device, integrated with a dedicated image analysis chip, and built-in deep learning algorithms. It can perform real-time analysis on the ink droplet images collected by the camera. When receiving the flash inkjet instruction from the host computer, the system board controls the nozzle to eject ink, and at the same time controls the flashing time, spectral combination, etc. of the exposure lamp group, and triggers the camera to perform precise ink droplet image capture according to the flashing state of the exposure lamp. After receiving the image, the image analysis chip automatically identifies the shape of the ink droplets, such as round, oval, irregular shape, etc., size (accurate to the micron level) and speed characteristics, calculates using the position distance and time interval between the first capture and the second capture, and compares the analysis results with the preset ink droplet quality standards, and outputs the ink droplet state evaluation results, such as qualified, unqualified and marks specific problems, such as the ink droplet shape is not round, the speed is too slow, etc.

[0044] The host computer is a high-performance computer installed with customized ink droplet observation control software. On the software interface, it real-time displays the high-definition ink droplet images captured by the camera, as well as various ink droplet parameters and state evaluation results analyzed and output by the system board. When the ink droplet state is not ideal, technicians can input adjustment instructions, and the host computer sends the instructions to the system board. The system board adjusts the waveform driving parameters according to the instructions, thereby changing the inkjet state of the nozzle. In addition, the host computer also has the function of storing and managing historical observation data, and can automatically optimize the printing parameter suggestions according to these data.

[0045] The camera is a high-speed, high-resolution camera with intelligent focusing function. The camera is MV-GE134GM-T-CL, and its capture lens type is DHO7-4.5. The camera automatically focuses quickly according to the movement state and position change of the ink droplet, ensuring that the ink droplet image can be clearly captured at different spraying speeds.

[0046] The system board integrates a dedicated image analysis chip. The chip is built with deep learning algorithms for real-time analysis of the ink droplet images collected by the camera, automatically identifying the shape, size and speed characteristics of the ink droplets, and comparing them with preset standards to directly output the evaluation results of the ink droplet state.

[0047] The exposure lamp group uses multi-spectral LED lights to emit lights of different spectra. The system board controls the spectral combination and brightness of the exposure lamp group according to the characteristics of the ink droplets and the observation requirements, enhancing the contrast of the ink droplet images to facilitate observing the internal structure and boundary of the ink droplets.

[0048] The system board also includes a data storage module for storing historical ink droplet observation data, printing task data and corresponding printing quality feedback data. The data storage module uses distributed encryption storage technology to disperse and store data in multiple storage units and encrypt the data. The system board uses these data for data analysis to establish an association model between the ink droplet state and printing quality, providing data for ink droplet state prediction and printing parameter adjustment.

[0049] The display interface of the host computer uses virtual reality or augmented reality technology to display the three-dimensional model, movement trajectory and dynamic changes of various parameters of the ink droplets in an immersive or enhanced manner.

[0050] When adjusting the nozzle waveform drive parameters, the system board uses an adaptive optimization algorithm to dynamically adjust the optimization direction and step size according to the real-time state of the ink droplets and the historical adjustment effect, finding the optimal waveform drive parameter combination to achieve the adjustment of the ink droplet spraying state.

[0051] In specific operations, the user opens the host computer software, selects the nozzle type and ink characteristics, and sets the standard of the droplet parameters to be observed, such as the droplet diameter is 30±2 microns, the ejection speed is 5±0.5 m / s, etc.; the software sends the relevant parameters to the system board, and the system board controls the nozzle to eject a small amount of ink. At the same time, the exposure lamp group flashes according to the preset spectral combination and brightness, providing clear lighting conditions for the droplets; under the control of the system board, the high-speed camera accurately captures the images of the droplets from the nozzle ejection to the flight process, and transmits the image data to the system board in real time; the image analysis chip of the system board analyzes the images, automatically identifies the shape, size, speed, etc. of the droplets. After comparing with the preset standards, it is found that the droplet shape is slightly irregular and the ejection speed is slightly slower; the host computer displays the droplet images and problem descriptions in real time, and the R & D personnel adjust the nozzle waveform drive parameters according to experience or refer to the system suggestions, such as increasing the drive voltage and adjusting the drive frequency. The host computer sends the new parameters to the system board; the system board controls the nozzle to inkjet again, and the exposure lamp group and the camera work together again to capture and analyze the droplet images. After several adjustments and observations, the droplet state gradually reaches the ideal state and meets the printing quality requirements.

[0052] Embodiment 2

[0053] A method for adjusting droplets, as Figure 2 shown, includes the following steps:

[0054] The host computer sends a flash inkjet command to the system board; after receiving the flash inkjet command, the system board controls the nozzle to inkjet and simultaneously controls the exposure lamp group to flash; according to the flashing state of the exposure lamp group, the camera captures the state information of the droplets at the nozzle position, including the position, size and roundness of the droplets, and transmits the captured droplet information to the system board, and the system board then sends the processed droplet information to the host computer for display.

[0055] By setting different flashing times of the exposure lamp group, the position information of the droplets is captured twice; the host computer calculates the ejection speed of the droplets during this time period according to the distance between the positions of the droplets captured twice and the corresponding time interval.

[0056] The host computer judges whether the droplet state is ideal based on the obtained droplet state information and the calculated droplet ejection speed; if not, the host computer sends an adjustment command to the system board, and the system board adjusts the waveform drive parameters according to the adjustment command to change the inkjet state of the nozzle until the droplet state reaches the ideal state.

[0057] A device includes a processor, a memory, and a computer program stored on the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the above-mentioned droplet adjustment method.

[0058] A storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of the above-mentioned ink droplet adjustment method are implemented.

[0059] In a specific implementation, a multi-column nozzle array dedicated to a printed circuit board inkjet printer, each column contains dozens of tiny nozzles, which can simultaneously eject high-precision ink droplets according to the circuit pattern of the circuit board. The ink is a conductive metal ink and is used for the circuits of the printed circuit board; a multi-group of LED strong lights of an exposure lamp group that move on the track of the printer are both located at both ends of the printing area and are opposite to the nozzles, providing sufficient illumination for photographing the ink droplets. Its spectral combination can penetrate part of the layer of the metal ink and clearly display the flight trajectory of the ink droplets in the air and the initial state of attachment to the circuit board substrate. The camera is installed on the printing workbench, facing the nozzles and the working area of the printed circuit board. An industrial-grade MV-GE134GM-T-CL camera is used, which has a strong autofocus function and can quickly adapt to the reflection changes of the ink droplets and the surface of the circuit board substrate. With its high resolution and high-speed capture ability, it can clearly present the uniformity, diffusion degree, line clarity, etc. after the ink droplets are attached to the circuit board substrate; the system board is connected to the production control system of the factory, integrating an advanced image analysis chip and a data storage module. In addition to analyzing the conventional parameters of the ink droplets, the chip also combines the characteristics of the circuit board substrate, such as surface roughness, tensile strength, etc. and the special properties of the ink, such as conductivity, drying time, to predict and monitor the attachment effect and drying and forming process of the ink droplets. The data storage module uses distributed encryption storage technology to disperse and store historical observation data and corresponding printing quality feedback data, such as short circuits and open circuits in the circuit board inspection report, and automatically establishes an association model between the ink droplet attachment quality and the qualified rate of printed products; the upper computer is a terminal computer connected to the workshop information network, with a virtual reality (VR) display function. The ink droplet observation interface can be switched to the VR mode. As long as the technical personnel wear VR glasses, they can see the 3D dynamic process of the ink droplets flying in the air and attaching to the circuit board substrate after being ejected from the nozzles, and intuitively observe the morphological changes and diffusion of the ink droplets at different angles and distances. At the same time, the upper computer can also display the ink droplet parameter data of each nozzle in real time, including the ink droplet consistency status of each column of nozzles, and compare it with the preset standard.

[0060] Technicians turn on the VR ink droplet observation software of the host computer, select the corresponding working mode of the inkjet printer for printed circuit boards, set the specifications of the circuit boards to be produced and the ink characteristic parameters, and start a series of nozzles for test inkjet; under the control of the system board, the exposure lamp group flashes according to a predetermined time sequence, providing stable lighting conditions for the observation of ink droplets, ensuring that the camera can capture the entire flight process of the ink droplets and the moment when they adhere to the circuit board substrate; the images collected by the camera are transmitted to the system board in real time, and the image analysis chip analyzes each ink droplet ejected by each column of nozzles one by one, detecting the size consistency of the ink droplets, the flight speed uniformity, the position accuracy and shape integrity when adhering to the substrate, etc. At the same time, the data storage module automatically retrieves the historical data related to the workpiece type and compares it with the current ink droplet parameters to predict possible quality problems, such as circuit disconnection that may be caused by poor ink droplet adhesion; through the VR display interface of the host computer, technicians can immersively observe the slight deviation trajectory of the ink droplets during flight in the air affected by the air flow after being ejected, and the diffusion situation of the ink droplets after adhering to the circuit board substrate under the action of the surface tension of the ink and the adsorption force of the substrate. It is found that the ink droplet deviation of a certain column of nozzles exceeds the standard. The system board initially judges that it may be caused by improper waveform drive parameter settings. Technicians determine a new waveform drive parameter adjustment plan based on experience, such as increasing the rise time of a certain section of the waveform, and sending it to the system board through the host computer. The system board uses an adaptive optimization algorithm. When adjusting the parameters, it comprehensively considers the current ink droplet state and historical adjustment records, and dynamically fine-tunes the optimization parameter step size to quickly stabilize the inkjet state of the nozzles. After several adjustment feedback cycles, the ink droplet deviation problem is solved, and the adhesion position accuracy meets the requirements, ensuring good electrical performance of the printed circuit board lines produced.
