DETAILED DESCRIPTION

[0017] The following is a clear and complete description of 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 making creative efforts are within the scope of protection of the present invention.

[0018] refer to Figures 1 to 3 , a coding method for anti-counterfeiting and quality traceability of perfect-bound books and periodicals, specifically comprising: Generate printing characters based on key information such as production date, production time, production machine number, serial number, number of product signatures and glue type according to anti-counterfeiting code coding rules; In the process of perfect binding of books and periodicals, the inner side of the spine of the cover is selected as the inkjet coding location; Using a small character inkjet coding device to perform inkjet coding operation on the upper cover workstation of the perfect binding machine based on the inkjet printing characters and inkjet coding positions, thereby forming an anti-counterfeiting code for the perfect-bound books and periodicals; Based on the established quality traceability system, the anti-counterfeiting codes of perfect-bound books and periodicals are scanned and analyzed to obtain the traceability results.

[0019] In this embodiment, according to the anti-counterfeiting code coding rules, the printed characters are generated by combining multi-dimensional key information such as production date, production time, production machine number, serial number, number of product signatures and glue model, thereby ensuring the uniqueness of the anti-counterfeiting code of each perfect-bound book and periodical. This uniqueness makes it difficult for counterfeiters to copy, thereby effectively improving the anti-counterfeiting ability of perfect-bound books and periodicals. The coding position is selected on the inner side of the spine of the cover, which is relatively hidden and not easily directly accessible, reducing the risk of the security code being tampered with or replaced. By printing the anti-counterfeiting code containing key production information and combining it with the established quality traceability system, the entire process of perfect-bound books and periodicals from production to sales can be traced. Once a quality problem is found, the specific production batch, operation link and raw materials used can be quickly located, providing strong support for problem investigation and resolution. The combination of inkjet coding method and quality traceability system realizes the integrated management of production data. Enterprises can use the traceability system to monitor production status in real time, analyze production data, and discover potential production problems or improvement points, thereby optimizing production processes and improving production efficiency. Through the traceability analysis of production data, enterprises can promptly discover and correct errors or deviations in the production process, reducing the risks of returns and recalls caused by production problems. Consumers can verify the authenticity and quality information of products by scanning the anti-counterfeiting code on the bound books and periodicals. This transparent traceability mechanism enhances consumers' trust in products and improves brand image. The convenient query method provided by the quality traceability system enables consumers to easily obtain detailed information about products, including production date, production location, source of raw materials, etc., satisfying consumers' demand for the right to know about products.

[0020] It should be noted that the key technical parameters of the inkjet coding process are: Single line printing speed is not less than 2m / s; The number of printed lines is at least 1; Character height is limited to 24 points; Use quick-drying ink for printing; The printing delay time is precisely matched to the conveyor belt speed, with the error controlled within ±0.1 seconds.

[0021] The anti-counterfeiting code for printed perfect-bound books and periodicals adopts a composite data structure, specifically including: Combination of production date and production time; The association information between the production machine number and the serial number; The corresponding information between the number of product signatures and glue type.

[0022] Preferably, in the process of binding books and periodicals, the inner side of the spine of the cover is selected as the coding position, which specifically includes: Identify the cover-adding station in the binding process of perfect-bound books and periodicals as the key coding node; At the cover workstation, dynamic three-dimensional positioning technology is used to select the coding position on the inside of the cover spine. The dynamic three-dimensional positioning technology is based on the thickness of the book, the size of the book format and the dynamic changing parameters during the transmission process. Through comprehensive calculation, the optimal coding area in the middle of the spine is determined. The optimal coding area is within the adhesive contact surface between the cover and the book core.

[0023] In this embodiment, by adopting dynamic three-dimensional positioning technology, the solution can perceive the dynamic changing parameters of books and periodicals during the transmission process in real time, such as position offset, tilt angle, etc., and perform comprehensive calculations based on the thickness and size of the books and periodicals. This dynamic adjustment mechanism ensures the accuracy of the coding position selection and avoids coding deviations caused by slight changes in the books and periodicals during the transmission process. Through precise calculation, the solution can determine the optimal coding area in the middle of the spine. This area is not only within the adhesive contact surface between the cover and the book core, ensuring the firmness and durability of the coding, but also avoiding key parts that may affect the aesthetics and structural strength of the books and periodicals; the coding position is selected on the inner side of the spine of the cover. This relatively hidden position makes the coding information not easy to be directly observed, thereby increasing the difficulty for counterfeiters to copy and tamper with it, and effectively improving The anti-counterfeiting effect, combined with the optimal coding area determined by dynamic three-dimensional positioning technology, further ensures the uniqueness of the coding position of each perfect-bound book and periodical, providing strong support for anti-counterfeiting; the application of dynamic three-dimensional positioning technology makes the coding process automated and intelligent, reduces the need for manual intervention and adjustment, and improves production efficiency. By precisely controlling the coding position, this solution reduces the defective rate caused by coding position deviation and improves the stability and reliability of the production process; the precise selection and firmness of the coding position ensures the clarity and readability of the coding information during the subsequent use of the perfect-bound book and periodical, thereby improving the overall quality of the product. For consumers, they can easily find and verify the coding information, which enhances their trust and satisfaction with the product. At the same time, the hidden coding position will not affect the aesthetics and reading experience of the book and periodical.

[0024] Preferably, the dynamic three-dimensional positioning technology is based on the thickness of the book, the size of the book, and the dynamic change parameters during the transmission process, and determines the optimal coding area in the middle of the spine through comprehensive calculation, specifically including: Use sensors to monitor the position and speed of perfect-bound books and periodicals on the conveyor belt in real time; Analyze the thickness and size of books and periodicals through image recognition technology to adjust the size, length and width of the inkjet characters; Based on the position and speed of the bound books and periodicals on the conveyor belt, as well as the size, length and width of the coding characters, the optimal movement path and printing timing of the coding terminal are calculated to obtain the optimal coding area.

[0025] In this embodiment, sensors are used to monitor the position and speed of the bound books and periodicals on the conveyor belt in real time, which can quickly capture the dynamic changes of the books and periodicals and provide accurate data support for subsequent coding operations. This real-time monitoring mechanism ensures that the coding process can be dynamically adjusted according to the actual position and speed of the books and periodicals, thereby improving the accuracy of coding. By analyzing the thickness and size of the books and periodicals through image recognition technology, the size, length and width of the coding characters can be automatically adjusted to accommodate books and periodicals of different specifications. This adaptive adjustment capability enables the coding equipment to be applicable to various types of bound books and periodicals, thereby improving the versatility and flexibility of the equipment. Based on the position and speed of the bound books and periodicals on the conveyor belt, as well as the size, length and width of the coding characters, the optimal moving path and printing timing of the inkjet terminal are calculated. This precise calculation Calculation and planning ensure that the inkjet terminal can perform coding operations at the most appropriate time and location, thereby improving coding efficiency. By accurately calculating the optimal movement path and printing timing, the error and defective rate caused by coding position deviation or inappropriate printing timing can be greatly reduced, thereby improving the stability and reliability of the production process. Determining the optimal coding area in the middle of the spine and ensuring the clarity and accuracy of the coded characters will help enhance the anti-counterfeiting effect of the anti-counterfeiting code. At the same time, the selection of this area will also facilitate subsequent scanning and analysis by the quality traceability system. Combined with dynamic three-dimensional positioning technology and precise coding operations, it can ensure that the coding information of each bound book is unique and can be fully traced through the quality traceability system. This uniqueness and traceability provide strong support for product anti-counterfeiting and quality traceability.

[0026] Preferably, the method of calculating the optimal moving path and printing timing of the inkjet terminal based on the position and speed of the bound books and periodicals on the conveyor belt, and the size, length and width of the inkjet coded characters, specifically includes: Real-time acquisition of the position of the bound books and periodicals on the conveyor belt in the X, Y, and Z directions, as well as the velocity components Vx, Vy, and Vz in the X, Y, and Z directions; Determine the relative position ratio k of the inkjet characters on the inner side of the spine of the cover of the perfect-bound book or periodical according to the specification parameters of the perfect-bound book or periodical and the preset size of the inkjet characters; The optimal movement path and printing timing of the inkjet terminal are calculated based on the position of the bound book on the conveyor belt in the X, Y, and Z directions, the velocity components Vx, Vy, and Vz in the X, Y, and Z directions, and the relative position ratio k of the coding characters on the inner side of the spine of the bound book cover.

[0027] In this embodiment, the position and speed components of the perfect-bound books and periodicals on the conveyor belt in the X, Y, and Z directions are acquired in real time. This multi-dimensional monitoring mechanism can more comprehensively grasp the dynamic state of the books and periodicals, providing a solid data foundation for the precise positioning of the inkjet terminal. Based on the specifications of the perfect-bound books and periodicals and the preset size of the inkjet characters, the relative position ratio k of the inkjet characters on the inner side of the cover spine is determined. This step ensures that the inkjet characters can be accurately printed on the books and periodicals according to the predetermined ratio and position, thereby improving the positioning accuracy of the inkjet codes. By comprehensively considering the position, speed, and relative position ratio of the books and periodicals, the optimal moving path of the inkjet terminal is calculated. This path planning can ensure that the inkjet terminal can print the books and periodicals in the shortest time and The coding task is completed with the minimum moving distance, which improves the coding efficiency. Combined with the speed and position information of the books and periodicals, as well as the moving path of the inkjet terminal, the printing timing can be accurately calculated, which avoids problems such as coding offset or blurring caused by improper printing timing, and improves the stability and quality of coding. Since the relative position ratio k of the coding characters is determined according to the specifications of the books and periodicals and the preset size of the coding characters, this technical solution can adapt to the binding books and periodicals of different specifications and sizes, improves adaptability and flexibility, monitors the position and speed changes of the books and periodicals on the conveyor belt in real time, and adjusts the moving path and printing timing of the inkjet terminal accordingly, which can cope with dynamic changes in the production process and maintain a stable coding effect.

[0028] It should be noted that, based on the above-obtained book position, speed and inkjet character parameters, the optimal movement path (Px(t), Py(t), Pz(t)) of the inkjet terminal and the inkjet printing timing (t0) are calculated using the following formula: Px(t) = X(t) + k*Sx, where Sx is the effective coding area width of the book in the X direction, which is related to the size of the book, S. X(t) is the position of the book in the X direction, which is affected by the speed Vx as time t changes (i.e., the rate of change of X(t) is related to Vx). Py(t) = Y(t) + f(T,H,W), where f(T,H,W) is the offset in the Y direction calculated based on the book thickness T, character height H, and width W. Y(t) is the position of the book in the Y direction, and its change is related to the velocity Vy. Pz(t) = Z(t) + fixed offset, where the inkjet terminal is at the correct height inside the cover spine in the Z direction. Z(t) is the position of the book in the Z direction, and its change is affected by the speed Vz. The printing timing t0 is determined when the book position (X(t0), Y(t0), Z(t0)) meets certain conditions, that is, when the book reaches the predetermined coding position and the speed is stable.

[0029] Preferably, the construction of the quality traceability system specifically includes: The printed characters are associated with the basic product information of the books and periodicals to generate traceability data entries that can be stored in the database; Establish a mapping relationship between production scheduling information of perfect-bound books and periodicals and traceability data entries; A traceability algorithm and model are generated based on the mapping relationship. The traceability algorithm and model are used to search and match in the quality traceability database to locate the production batches and operation links related to the quality problem.

[0030] In this embodiment, the printed characters (anti-counterfeiting code) are associated with the basic product information of books and periodicals (such as specifications and materials) to form a unique traceability entry, ensuring that the production data of each book and periodical can be independently traced. Combined with the mapping relationship of production scheduling information (such as batch, machine, and operator), the problem link can be quickly identified. The traceability algorithm is designed based on the mapping relationship and supports multi-dimensional retrieval based on anti-counterfeiting code, production date, batch number, etc., and quickly matches the associated data in the database. The traceability system can monitor the correlation between production data and quality feedback in real time. For example, if a machine repeatedly experiences inkjet code deviation problems within a specific time period, the system can automatically trigger an alert, prompting maintenance personnel to inspect the equipment. The traceability data entries can be expanded to include supplier information (such as glue batch and paper source), realizing full-chain quality traceability. If there are quality issues with the raw materials, the affected batches can be quickly recalled to reduce corporate losses.

[0031] It should be noted that the specific steps for generating the traceability algorithm and model based on the mapping relationship include: Conduct in-depth analysis of the mapping relationship between established production schedule information for perfect-bound books and periodicals and traceability data entries, clarifying the association logic between various production factors (such as production time, production machine number, serial number, glue type, raw material batch, process parameters, etc.) and corresponding fields in the traceability data entries; The parsed mapping relationship is structured to form a standardized data association model, which defines the specific correspondence between each production factor and the traceability data item and the data interaction method; Based on the structured mapping relationship model, a traceability algorithm is designed, which includes the following core functions: Input processing module: receives user input of quality problem description, abnormal product identification or traceability query request, and converts it into query conditions that can be recognized by the system; Retrieval and matching module: Using query conditions, it conducts efficient retrieval and matching based on the mapping relationship model in the quality traceability database, quickly locating the production batches and operation links related to quality issues; Result integration module: Integrates the retrieved relevant information to form a complete traceability report, including production batch information, operation link records, relevant production scheduling information, and analysis of possible causes of quality problems; Based on the designed traceability algorithm, a traceability model is constructed, which includes the following components: Data layer: stores all data in the quality traceability database, including traceability data entries, production scheduling information, and the mapping relationship between the two; Logic layer: implements the core logic of the traceability algorithm, including input processing, search matching, and result integration; Interface layer: provides interactive interfaces with external systems, supports user queries, data import and export, and integration with other management systems.

[0032] Preferably, the method further comprises: During the perfect binding process, the outer layer of cover paper covers the area where the security code is sprayed, and the glue penetrates into the paper fibers to form an additional layer of protection.

[0033] In this embodiment, the outer layer of paper on the cover directly covers the anti-counterfeiting code, forming the first physical barrier to resist friction and scratches during transportation, storage and use. For example, if books and periodicals collide frequently during logistics, the outer layer of paper can prevent the security code from being scratched and causing information loss; the glue penetrates the paper fibers and solidifies to form a dense protective layer, which can resist erosion by sweat, oil stains and other chemicals. For example, when consumers flip through the pages for a long time, the oil on their hands will not penetrate into the surface of the security code, avoiding blurred information; after the security code is covered by the outer layer of paper, it can only be seen through specific methods (such as observation through light, partial windowing), increasing the difficulty for counterfeiters to copy. For example, if ultraviolet light is required for development, ordinary printing equipment cannot reproduce it.

[0034] A coding system for anti-counterfeiting and quality traceability of perfect-bound books and periodicals, comprising: The printing character generation module is used to generate corresponding printing characters based on the key information of the obtained production date, production time, production machine number, serial number, number of product signatures and glue model according to the preset anti-counterfeiting code encoding rules; The coding position determination module is used to determine the inner side of the spine of the cover as the coding position during the binding process of perfect-bound books and periodicals; A coding execution module is used to use a small character coding device to perform a coding operation on the upper cover workstation of the perfect binding machine based on the printing characters and the coding position to form an anti-counterfeiting code for the perfect bound book; The quality traceability system module is used to scan and analyze the anti-counterfeiting codes of perfect-bound books and periodicals based on the established quality traceability system to obtain traceability results.

[0035] A computing device comprises a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the processor implements any one of the steps of the above-mentioned coding method for anti-counterfeiting and quality traceability of perfect-bound books and periodicals.

[0036] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements any one of the steps of the above-mentioned coding method for anti-counterfeiting and quality traceability of perfect-bound books and periodicals.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
