Description

Technical Field

[0001] This invention relates to the field of round bottle printing technology, and more specifically, to a method, apparatus, and storage medium for improving the printing quality of a round bottle printer through multi-round printing in the same direction. Background Technology

[0002] In industrial production, round bottle surface printing technology is widely used in daily chemicals, food, and pharmaceutical fields to print trademarks, instructions, production dates, and other information on the surface of cylindrical bottles. However, traditional round bottle printing technology has many limitations, especially in terms of print quality and efficiency. Traditional single-round printing methods typically use a single printhead to print on the bottle surface in one pass. This method is easily affected by various factors such as the curvature of the bottle, the distance between the printhead and the bottle surface, and the ink jet angle, resulting in problems such as high drop heights in the printed pattern and uneven ink droplet distribution, which seriously affects print quality. In addition, traditional methods have poor adaptability to bottle materials and shapes, making it difficult to meet the high-quality printing needs of different customers.

[0003] With the development of technology, multi-round printing technology has been gradually introduced into the field of round bottle printing. Multi-round printing gradually covers the entire printing area through multiple prints, which can effectively improve print quality. However, existing multi-round printing technology still has some problems. For example, the coordinated control of nozzle movement and base plate during multi-round printing is not precise enough, resulting in unreasonable printing path planning and low printing efficiency. In addition, the processing method of printing data is relatively simple and cannot dynamically adjust printing parameters according to the three-dimensional parameters of the bottle, resulting in unsatisfactory printing results. During the printing process, there is a lack of real-time quality monitoring and dynamic parameter adjustment mechanisms, which makes it impossible to detect and correct deviations in the printing process in time, affecting the stability of print quality.

[0004] In summary, existing round bottle printing technologies suffer from problems such as unstable print quality, high drop height, uneven ink drop distribution, and poor adaptability to bottle shape and material. Summary of the Invention

First, by establishing a communication connection between the printing control software and the round bottle printing equipment, precise control of the printing process is achieved. Second, laser scanning technology is used to obtain a three-dimensional parameter dataset of the bottle, including the radius of curvature, height, and material properties, providing accurate basic data for printing path planning and parameter adjustment. Based on this data, a multi-round printing path planning scheme is generated, and the printing data is split into single-sided channel outputs according to a preset algorithm. The channel data is then sequentially adjusted according to the printing direction, thereby avoiding the high drop height problem caused by the difference in printing height between the two sides in traditional single-round printing. Simultaneously, through calculation... The maximum height difference of each axial section was calculated and a height difference compensation matrix was established to further optimize the printing path and ensure the flatness of the printed pattern. During the printing process, printing quality data was collected in real time and fed back to the control system.

Furthermore, this invention introduced an environmental monitoring and adaptive compensation mechanism, dynamically adjusting ink viscosity and surface tension parameters according to changes in ambient temperature and humidity. This enhanced the adaptability of the printing technology to different environmental conditions. Through these comprehensive measures, this invention not only improved the quality and efficiency of round bottle printing but also enhanced its adaptability to bottles of different shapes and materials, meeting customers' demands for high-quality printing.

[0035] Please see Figure 1 A method for improving the printing quality of a round bottle printer through unidirectional multi-round printing includes the following steps: establishing a communication connection between the printing control software and the round bottle printer; acquiring a three-dimensional parameter dataset of the bottle to be printed, including the radius of curvature, height, and material properties; generating a multi-round printing path planning scheme based on the three-dimensional parameter dataset; controlling the printhead to start the first round of printing at the printing starting point according to the printing path planning scheme; after the first round of printing is completed, moving the base plate so that the next printing channel corresponds to the center position of the bottle; repeating the printing and base plate movement operations until the preset number of unidirectional multi-round printings is completed; and collecting printing quality data in real time and feeding it back to the control system for dynamic parameter adjustment.

[0052] The quality monitoring module includes: a CCD image sensor for capturing print surface details; an image processing unit for extracting ink dot distribution features; and a quality assessment algorithm library for calculating print quality indicators.

[0053] The intelligent adjustment module includes: a machine learning processor for running a trained parameter optimization model; a real-time control unit for generating actuator adjustment instructions; and an adaptive compensation unit for handling environmental interference factors.

[0054] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the above-described method steps for improving the printing quality of a round bottle machine through co-directional multi-round printing.

[0055] The round bottle printer involved in this embodiment is equipped with 8 nozzle channels. Each printing operation uses 2 channels to work together, completing the printing task of the entire bottle in 4 rounds. The bottle to be printed is a standard cylindrical glass bottle made of transparent glass with stable surface properties, which is suitable for high-precision printing. This combination of equipment configuration and printing object requires a high degree of coordination and precision in the printing process to ensure the final print quality.

[0056] The printing control software and the round bottle printing equipment establish a communication connection via an RS232 serial port, using the standard Modbus protocol as the data transmission rule. This protocol can standardize the data transmission format and interaction method, ensuring that control commands are accurately sent from the software to the device. At the same time, the device's operating status information can also be fed back to the control software in a timely and complete manner. This communication connection is the foundation for the entire printing process, providing information transmission support for subsequent parameter settings, path planning, and printing execution.

[0057] A laser scanner is used to perform a full-range, high-precision scan of the bottle to be printed. During the scanning process, the laser beam can capture every detail on the surface of the bottle, thereby obtaining the curvature distribution characteristics of the bottle. At the same time, the core parameters such as the height and radius of the bottle are collected simultaneously. These parameters together constitute a complete three-dimensional shape model of the bottle.

[0058] Based on the obtained bottle radius R and the preset nozzle spray angle θ, the height difference of each axial section is calculated using the formula ΔH=R(1-cosθ). This height difference reflects the dynamic distance change between the nozzle and the bottle surface at different positions, which is the key basis for realizing height compensation during the printing process and can ensure that the nozzle always maintains a suitable distance from the bottle during the printing process.

[0059] Based on the natural segmentation pattern of the printed area, the calculated height difference data are integrated to construct a height difference compensation matrix. , where n is the number of printing area segments, and each element in the matrix corresponds to the compensation value of a printing area. This method ensures that the printhead can adjust its height in real time in different printing areas, always maintaining the optimal printing distance, thus laying the foundation for high-quality printing.

[0060] Based on the rule of printing in 4 rounds across 8 channels, a preset optimization algorithm is used to reasonably divide the total print data D into 4 subsets, namely D1 to D4. Each subset corresponds to a specific print task in one round. During the data splitting process, the coverage and printing capacity of each channel are considered to ensure that the amount of data in each data subset can match the printing requirements of the corresponding round, thereby achieving a balanced distribution of data.

[0061] Based on the physical arrangement characteristics of the printhead, a dedicated channel combination is matched for each round of printing tasks. For example, the first round uses channel 1 and channel 2, the second round uses channel 3 and channel 4, and so on. By establishing a fixed mapping relationship table between rounds and channels, the hardware division of labor at each stage is clarified, avoiding confusion in channel usage and ensuring the orderly progress of the printing process.

[0062] Considering the cylindrical nature of the bottle, to avoid the potential accumulation of errors from unidirectional printing, an alternating printing direction is designed. For example, the first round of printing uses a left-to-right direction, while the second round changes to a right-to-left direction. The printing direction is adjusted by horizontally flipping the data, thereby improving the uniformity and accuracy of the printed pattern.

[0063] By integrating the printhead's motion trajectory, the base plate's displacement logic, and timing control rules, a complete integrated instruction set is generated. This instruction set specifies the printhead's movement path, the base plate's rotation angle, and the timing of the transitions between each action during each printing cycle, ensuring that the printhead and base plate can work together to complete each printing task.

[0064] The first round of printing started strictly according to the planned scheme from the set starting point. During the printing process, the printhead adjusted its height in real time according to the height difference compensation matrix to ensure a precise distance from the bottle surface, thereby ensuring the inkjet effect and the clarity of the pattern.

[0065] After each printing cycle, the base plate rotates the bottle at a preset angle, ensuring that the next set of channels is precisely aligned with the center of the unprinted area, achieving seamless transitions between cycles and preventing printing overlaps or omissions.

[0066] Repeat the printing and displacement process described above continuously. After four rounds of printing, the entire bottle is fully covered. The superposition effect of multiple printing rounds can improve the fullness and uniformity of the pattern, making the final printing effect more ideal.

[0067] By combining laser scanning and image recognition, the surface condition of the bottle after each printing cycle is captured in real time, and key feature indicators such as the distribution density and uniformity of ink dots are extracted. These indicators can reflect the quality of printing.

[0068] The actual extracted quality indicators are compared with the preset standards to calculate the deviation value and analyze the reasons for the deviation in depth. Once problems such as sparse ink dots or uneven distribution are found, the parameter adjustment mechanism is immediately triggered to ensure that the printing quality can be corrected in a timely manner.

[0069] The system calls a pre-trained machine learning model based on a historical printing database containing data on material properties, environmental parameters, and the correlation between printing results and quality. By inputting current printing status data, the model can quickly generate optimization plans and dynamically adjust key parameters such as ink volume and printing speed.

[0070] The optimized parameters are fed back to the control system in real time, and these adjustments are executed in the next printing process, forming a closed-loop control process of monitoring, analysis and optimization to continuously improve print quality.

[0071] Throughout the printing process, the temperature and humidity of the printing environment are continuously monitored, as these factors directly affect the viscosity and surface tension of the ink, thus significantly impacting the printing results. Therefore, they serve as important references for parameter adjustments.

[0072] By combining the material properties of transparent glass, a mapping model between environmental parameters and ink performance is established. When temperature and humidity fluctuate, the state of the ink can be automatically adjusted to ensure that its adhesion to the bottle surface remains stable and to avoid a decline in print quality due to changes in ink performance.

[0073] By constructing a parameter adaptive compensation mechanism, multiple variables such as environmental factors and print quality deviations are incorporated into a unified control system to achieve dynamic balance across printing cycles. This mechanism enables the printing process to have stronger environmental adaptability and ensures that high-quality print results can be stably output under different environmental conditions.

[0074] Example 2

[0075] Please see Figure 2 The electronic device in this embodiment comprises:

[0076] The communication module is built based on RS232 serial port and Modbus protocol, and is used for bidirectional communication between the control software and the round bottle machine. This module has efficient data processing capabilities, which can ensure the real-time and accuracy of instruction transmission, and ensure that the instructions of the control software can be quickly received and executed by the round bottle machine. At the same time, the operating status of the round bottle machine can also be fed back to the control software in a timely manner, realizing close cooperation between the two.

[0077] The data acquisition module integrates a laser scanner and a high-resolution CCD sensor. The laser scanner is mainly used to acquire the three-dimensional parameters of the bottle. By scanning the bottle comprehensively, it provides accurate geometric data for path planning. The high-resolution CCD sensor is used to capture microscopic images of the printing surface. These images contain printing quality information and are the raw data source for quality monitoring and parameter adjustment.

[0078] The path planning module, as the core planning unit of the printing logic, can generate a complete four-round printing plan based on the three-dimensional parameters provided by the data acquisition module. The plan covers data splitting, channel mapping, direction adjustment and instruction set generation. Through reasonable planning, it ensures that each round of printing can be carried out efficiently and accurately.

[0079] The main function of the motion control module is to drive the printhead and base plate to move in coordination and execute various actions according to the instructions generated by the path planning module. This module ensures the accuracy of the printing position and angle through precise control of the precision motor, so that the printhead and base plate can work together perfectly to complete each round of printing tasks.

[0080] The quality monitoring module consists of an image processing unit and a quality assessment algorithm library. The image processing unit can extract ink dot features, such as the size and distribution density of ink dots, from images acquired by a high-resolution CCD sensor. The quality assessment algorithm library analyzes and calculates these features using specific algorithms to derive quantitative quality indicators, providing a basis for judging the quality of printing.

[0081] The intelligent adjustment module includes a machine learning processor, a real-time control unit, and an adaptive compensation unit. The machine learning processor runs a trained model and generates optimized parameters by analyzing quality data. The real-time control unit converts these optimized parameters into specific actuator adjustment commands. The adaptive compensation unit specifically handles the interference of environmental factors on the printing process, ensuring the stability and consistency of the printing process.

[0082] The memory and processor are used to store important information such as printing data, model parameters, and historical records, providing data support for the operation of the device. The processor, as the central hub of the device, coordinates and controls the operation of various modules, ensuring that the entire system can work in an orderly manner according to the preset logic, and realizing the automation and intelligence of the printing process.

[0083] Equipment operation process: After the equipment is started, the communication module immediately and automatically establishes a connection with the round bottle machine to ensure smooth communication. At the same time, the data acquisition module quickly starts to scan the bottle and obtain its three-dimensional parameters, laying the data foundation for path planning and printing execution.

[0084] The path planning module receives the three-dimensional parameters provided by the data acquisition module, processes and analyzes them using internal algorithms, and generates a detailed plan for four rounds of printing. The plan specifies the channel combination, data allocation, printing direction, and action sequence for each round, and sends it synchronously to the motion control module.

[0085] The motion control module initiates the first round of printing based on the received printing plan. During the printing process, the printhead and base plate move in tandem according to the preset trajectory and timing to ensure printing accuracy. After each round of printing is completed, the device automatically switches to the next round and repeats the above process until all four rounds of printing are completed.

[0086] After each printing cycle is completed, the quality monitoring module immediately acquires an image of the bottle surface, processes and analyzes the image to evaluate the printing quality, and the intelligent adjustment module generates optimized printing parameters based on the quality evaluation results, combined with historical data and environmental parameters, and feeds them back to the motion control module in real time to adjust the next printing process, forming a complete quality control closed loop.

[0087] The device's built-in environmental sensors continuously monitor changes in temperature and humidity in the printing environment and transmit the monitoring data to the adaptive compensation unit in real time. Based on this data and the characteristics of the bottle and ink, the adaptive compensation unit dynamically adjusts the ink parameters and printing parameters to ensure stable printing conditions and improve the device's adaptability to environmental changes.

[0088] After all four printing cycles are completed, the equipment automatically stops running and notifies the user that the printing task is finished through preset prompts. At the same time, it saves relevant data of this printing, such as printing parameters and quality assessment results, to the memory to provide a reference for data analysis and process improvement.

[0089] Example 3

[0090] The storage medium consists of:

[0091] The operating system is the basic software in the storage medium. It manages the hardware resources of the device, provides a stable and efficient operating environment for each program module, and ensures that the entire system can operate in a coordinated and orderly manner by rationally allocating hardware resources and coordinating the work between modules.

[0092] The communication module program is used to implement RS232 serial communication and Modbus protocol parsing. This program can encode and decode data according to the protocol specifications, ensuring accurate information exchange between the control software and the round bottle machine, and providing reliable communication support for remote control and status monitoring of the equipment.

[0093] The data acquisition program controls the timing of the laser scanner and CCD sensor to ensure that they work together efficiently to acquire the bottle's three-dimensional parameters and surface images. At the same time, the program also preprocesses the acquired raw data to remove noise and interference, thereby improving the quality and usability of the data.

[0094] Based on the 3D parameters provided by the data acquisition program, the program performs logical operations such as data splitting, channel mapping, and instruction generation to generate a complete path plan for 4 rounds of printing. The program can flexibly adjust the planning strategy according to different bottle parameters and printing requirements to ensure the scientific validity and feasibility of the plan.

[0095] The motion control program transforms the path planning program's generated scheme into specific motor drive signals, controlling the movement of the printhead and base plate. By precisely controlling the motor's speed, direction, and displacement, it ensures the accuracy of the printing position and angle, achieving precise execution of the printing process.

[0096] The quality monitoring program includes image processing algorithms and a quality assessment model. The image processing algorithms can perform detailed processing on the images acquired by the CCD sensor and extract key information such as the distribution characteristics of ink dots. The quality assessment model calculates quantitative quality indicators based on these characteristics, providing an objective basis for judging print quality.

[0097] The intelligent adjustment program runs a machine learning model to conduct in-depth analysis of the quality data provided by the quality monitoring program, generating optimized printing parameters. At the same time, the program is also responsible for the linkage adjustment of environmental parameters and ink performance, ensuring the stability of the printing process and the consistency of print quality by dynamically correcting the printing parameters.

[0098] The storage management program is responsible for the comprehensive management of data in the storage medium, including operations such as storing, reading, updating, and deleting print data, model parameters, and historical records. By rationally organizing the data structure, it improves data access efficiency and ensures data security and integrity.

[0099] Storage media operation process: When the storage media is inserted into the device, the device will automatically load the operating system and related program modules. During the loading process, the system will initialize and configure each program, check the integrity and compatibility of the program, and ensure that the entire system can start and run normally.

[0100] The data acquisition program starts the laser scanner and CCD sensor according to the preset process to scan the bottle and acquire images. The acquired three-dimensional parameters and surface images are preprocessed and stored in the designated storage area to provide data support for path planning and quality monitoring.

[0101] The path planning program reads the three-dimensional parameters of the bottle from the storage area, processes and analyzes them using internal algorithms, and generates a detailed plan for four printing cycles. Once generated, the plan is immediately sent to the motion control program to provide a basis for printing execution.

[0102] The motion control program generates corresponding motor drive signals based on the received printing plan, controls the nozzle and base plate to move in coordination, and starts the first round of printing. After each round of printing is completed, the program automatically switches to the next round until all four rounds of printing are completed, ensuring full coverage printing on the bottle surface.

[0103] During each printing cycle, the quality monitoring program acquires images of the printed surface in real time, processes and analyzes them, calculates quality indicators, and the intelligent adjustment program generates optimized printing parameters based on the deviation of the quality indicators from the preset standards. These parameters are then fed back to the motion control program to adjust the next printing cycle, thereby achieving continuous optimization of print quality.

[0104] The program logic monitors the temperature and humidity changes of the printing environment in real time, and correlates the monitoring data with ink performance parameters. When environmental parameters fluctuate, it automatically adjusts the ink's viscosity, surface tension, and other performance parameters to ensure stable ink adhesion to the bottle surface and improve the printing process's adaptability to environmental changes.

[0105] Once all four printing cycles are complete, the program-controlled equipment stops operating and sends a notification to the user in a preset manner indicating that printing is complete. At the same time, it organizes and stores relevant data from this printing session, such as printing parameters, quality assessment results, and environmental parameters, forming a complete printing record to provide information for data analysis and process improvement.

[0106] The above embodiments comprehensively demonstrate a method for improving the printing quality of a round bottle printer through co-directional multi-wheel printing, as well as the specific structure and operation process of the electronic equipment and computer-readable storage medium for implementing the method. This reflects the value of co-directional multi-wheel printing technology in improving the printing quality of round bottle printers, while also ensuring the operability and repeatability of the technical solution, providing guidance for practical applications.
