Description

Technical Field

[0001] This invention relates to the field of bookbinding, specifically to a method for preparing a high-precision accordion-bound multi-volume book. Background Technology

[0002] Accordion-bound multi-volume books are a unique book format that combines the accordion folding binding structure with the continuity of content across multiple volumes. Each volume's pages are made by repeatedly folding a single long sheet of paper, resulting in a shape similar to an accordion bellows. These books can be read page by page or fully unfolded to form a continuous long image. With their unique unfolding effect and coherent content presentation, these books are widely used in popular science books, picture books, architectural guides, and other fields, providing readers with an immersive reading experience and a rich dimension of information acquisition.

[0003] None of the sewing machine manufacturers in the market have experience in producing books with a special structure like the *Mei Jian*, lacking readily available experience and technology to draw upon. Therefore, there is an urgent need for a new, high-precision manufacturing method to meet the production requirements of such books with unique structures. This method addresses the problems in existing technologies where the independent processing of each step leads to a lack of effective coordination and control, resulting in positioning errors, inconsistent shapes, or fluctuations in molding quality. This increases production costs and time, severely negatively impacting production efficiency and economic benefits. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method for preparing high-precision accordion-bound multi-volume books, solving the problem of a lack of effective coordination and control between various processes, which easily leads to positioning errors, inconsistent shapes, or fluctuations in molding quality, increasing production costs and time costs, and causing serious negative impacts on production efficiency and economic benefits.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for preparing a high-precision accordion-bound multi-volume book, comprising the following steps:

[0006] The cover or connecting medium that serves as the basis for the binding is pre-treated to form a stable binding standard.

[0007] The book block is divided into multiple booklets, and the multiple booklets are placed on the cover or connecting carrier in a predetermined order;

[0008] Based on the binding standard, each booklet is bound and positioned separately;

[0009] According to the binding positioning, each booklet is bound and fixed in sequence, so that each booklet is connected to the cover or connecting carrier respectively;

[0010] After each booklet is bound and secured, it is folded into shape.

[0011] After all the booklets have been bound, fixed, and folded, the overall structure is adjusted uniformly.

[0012] The adjusted conjoined structure is then compressed to complete the production of multiple conjoined books.

[0013] As a further description of the above technical solution: the cover or connecting carrier is preprocessed, including the following steps:

[0014] Set the position parameters of the binding reference;

[0015] A controlled hot pressing or flattening process is applied to the cover or connecting carrier;

[0016] The cover or connecting carrier is unfolded and corrected according to the position parameters;

[0017] Determine whether the cover or connecting carrier meets the flatness requirements for binding; if not, perform repeated correction operations.

[0018] The cover or connecting carrier is a sheet structure made of paper or composite material. The sheet structure is used to support multiple booklets and form an overall support for the accordion-bound book. The cover or connecting carrier is a sheet material used to support multiple booklets and serve as the overall binding reference. The pretreatment is used to release the internal stress in the sheet material and define its planar state.

[0019] By adopting the above technical solution, pre-treating the cover or connecting carrier before binding, and implementing controlled hot pressing or flattening treatment and unfolding correction operations based on the set binding reference position parameters, the internal stress in the sheet material of the cover or connecting carrier can be effectively released, its planar state can be limited, and it can maintain a stable geometric shape during the binding process. By judging the flatness of the pre-treated cover or connecting carrier and performing repeated correction operations when the requirements are not met, it can be ensured that its overall flatness meets the requirements for use as a binding reference. This can reduce the binding positioning error caused by warping, deformation or uneven stress of the cover or connecting carrier, improve the consistency and binding accuracy of multi-volume books in the binding, folding and overall forming process, and thus improve the finished product quality and structural stability of accordion-bound multi-volume books.

[0020] As a further description of the above technical solution: dividing the book block into multiple booklets includes the following steps:

[0021] The entire book block is paginated to ensure that the pages are arranged in the intended reading order.

[0022] Based on the overall structural design of the combined book, determine the start and end pages of each booklet;

[0023] A dividing line is set for the book block at the start page and the end page;

[0024] The book block is separated along the dividing boundary to form multiple independent booklet units.

[0025] The separated booklet units are aligned with their margins to form a booklet structure that can be bound and folded independently;

[0026] Each booklet unit, after completing the separation operation, maintains a continuous page order and is capable of being compiled into a separate booklet.

[0027] By adopting the above technical solution, page order correction is performed before separating the book block, and the start and end pages of each booklet are determined according to the overall structural design of the bound book. This ensures that the page arrangement of the book block always conforms to the predetermined reading order during the division process. By setting clear dividing boundaries at the start and end pages and performing the separation operation along these boundaries, it is ensured that the book block is accurately divided into multiple independent and clearly structured booklet units, avoiding page order errors or missing pages during the separation process. By aligning the page edges of the separated booklet units, each booklet forms a booklet structure suitable for independent binding and folding, thereby improving the stability and consistency of subsequent binding and folding processes. This ensures that each booklet maintains continuous page order and is capable of being bound separately after separation, providing a reliable foundation for the overall binding quality and finished product consistency of accordion-bound multi-book bound books.

[0028] As a further description of the above technical solution: placing the plurality of booklets on the cover or connecting carrier includes the following steps:

[0029] Set the arrangement order of multiple booklets on the cover or connecting medium;

[0030] Place the booklets in the order described above;

[0031] Determine if the placement order of each booklet is consistent with the predetermined order, and trigger an order adjustment operation if they are inconsistent;

[0032] After adjusting the order, confirm that each booklet is correctly positioned and maintains the predetermined spacing from the previous booklet.

[0033] By adopting the above technical solution, and by pre-setting the arrangement order of multiple booklets before placing them on the cover or connecting carrier, and placing each booklet in sequence according to the arrangement order, the booklets can form a spatial arrangement relationship that meets the design requirements in the overall connected structure. By judging the placement order of each booklet and triggering the order adjustment operation when it does not conform to the predetermined order, the problems of booklet misalignment, inversion, or disordered order can be effectively avoided. This can improve the consistency of the arrangement of multiple booklets on the cover or connecting carrier and the accuracy of pre-binding preparation, reduce the difficulty of adjustment in subsequent processes, and improve the binding quality and forming stability of the overall structure of the accordion-bound multi-book connected book.

[0034] As a further description of the above technical solution: binding and positioning each booklet based on the binding standard includes the following steps:

[0035] Set the positioning parameters of each booklet relative to the binding reference;

[0036] The binding position of each booklet is determined based on the positioning parameters.

[0037] The binding position is verified, and its consistency with the binding reference is confirmed.

[0038] If the verification fails, a positioning adjustment operation is triggered to ensure that the binding position of each booklet is correct.

[0039] By adopting the above technical solution, and by setting the positioning parameters of each booklet relative to the binding reference, and determining the corresponding binding position accordingly, the binding position of each booklet has a unified and clear reference. By verifying the consistency between the binding position and the binding reference, and performing positioning adjustment operations when there is a discrepancy, binding deviations can be corrected in a timely manner, ensuring that each booklet is accurately bound and positioned. This effectively improves the positioning accuracy and consistency in the binding process of multiple books, providing a reliable guarantee for subsequent binding and overall shaping.

[0040] As a further description of the above technical solution: the booklets are bound and fixed in sequence, including the following steps:

[0041] Select the booklets to be bound according to the predetermined binding order;

[0042] Perform the binding and securing operation at the corresponding binding position;

[0043] Determine if the current booklet is bound and secured, and switch to the next booklet if it is.

[0044] During the binding process, it is determined whether the binding process meets the quality standards, and corrective actions are performed if it does not.

[0045] By adopting the above technical solution, and by performing binding and fixing operations on each booklet in a predetermined binding order, multiple booklets can be bound and connected in an orderly manner. By judging the binding completion status and binding quality of each booklet, and performing correction operations when the quality standards are not met, binding defects can be eliminated in a timely manner, improving the stability and consistency of the binding and fixing process of each booklet, and ensuring the overall binding quality of multiple connected books.

[0046] As a further description of the above technical solution: folding the booklet includes the following steps:

[0047] Set the booklet's folding direction parameters;

[0048] Perform a folding operation on the bound booklet according to the folding direction parameters;

[0049] Determine whether the folded booklet has formed the predetermined shape, and perform a folding adjustment operation if it has not.

[0050] By adopting the above technical solution, by pre-setting the folding direction parameters of the booklet, and performing folding operations on the bound booklet according to the parameters, the booklet can be folded into shape in the predetermined direction. By judging the shape of the booklet after folding, and performing folding adjustment operations when the predetermined shape is not formed, folding deviations can be corrected in time, improving the accuracy and consistency of the booklet folding process, and ensuring the folding effect and overall structural quality of accordion-bound multi-book sets.

[0051] As a further description of the above technical solution: The overall integrated structure is uniformly adjusted, including the following steps:

[0052] Set the alignment reference for the overall integrated structure;

[0053] The overall position of each folded booklet is adjusted according to the alignment reference.

[0054] Determine if the overall structure meets the alignment requirements, and perform readjustment if it does not.

[0055] By adopting the above technical solution, by setting an alignment benchmark for the overall integrated structure, and adjusting the overall position of each folded booklet according to the alignment benchmark, the multi-book integrated structure can form a unified arrangement. By judging whether the overall structure meets the alignment requirements, and performing readjustment when it does not, the cumulative deviation between the booklets can be eliminated, improving the alignment consistency and forming stability of the overall structure of the accordion-bound multi-book integrated book, and providing a guarantee for subsequent pressing and final product quality.

[0056] As a further description of the above technical solution: the compression process of the integral structure includes the following steps:

[0057] Set the clamping position and clamping sequence;

[0058] Perform the clamping operation on the integrated structure according to the clamping sequence;

[0059] Determine whether the compaction process is complete, and confirm the end of the preparation process based on the determination result.

[0060] By adopting the above technical solution, by pre-setting the pressing position and pressing sequence of the integrated structure, and performing the pressing operation on the integrated structure in the order, the overall structure can obtain a stable stress state in the final forming stage. By judging the completion state of the pressing process and confirming the completion of the preparation, it is possible to ensure that the pressing process is fully implemented, effectively improve the overall structure of the accordion-bound multi-volume integrated book and the forming stability, and ensure the structural quality of the final product.

[0061] As a further description of the above technical solution: binding and positioning each booklet based on the binding standard also includes the following steps:

[0062] Before binding and positioning, the edges of each booklet already set on the cover or connecting carrier are aligned and corrected to unify the relative initial position of each booklet;

[0063] During the binding and positioning process, the position of each booklet relative to the binding reference is checked in real time.

[0064] After binding and positioning are completed, the consistency of the binding and positioning results of each booklet is confirmed. If any inconsistency is confirmed, the binding and positioning steps are repeated for the corresponding booklet.

[0065] By adopting the above technical solution, the initial relative positions of each booklet, which has been set on the cover or connecting carrier, can be unified by aligning and correcting the edges before binding and positioning, thereby reducing subsequent positioning deviations. By verifying the position of each booklet relative to the binding reference in real time and confirming the consistency of the positioning results after positioning, inconsistencies in positioning can be detected and corrected in a timely manner, improving the accuracy and consistency of the binding and positioning process of each booklet and ensuring the stability of the overall binding quality of multi-book binding.

[0066] This invention provides a method for preparing a high-precision, multi-volume, accordion-bound book. It has the following beneficial effects:

[0067] 1. In this invention, by introducing a benchmark parameter setting and result judgment mechanism for each process of binding positioning, folding and forming, overall alignment and pressing, closed-loop control of the book preparation process is realized, resulting in the effect that each booklet is in the same position in the overall structure, has a stable shape and controllable forming quality.

[0068] 2. In this invention, by performing edge alignment correction on each booklet before binding and verifying its position relative to the binding reference in real time during the binding process, the binding error is controlled in the initial stage, resulting in consistent binding position height for each booklet and reliable binding reference.

[0069] 3. In this invention, by setting folding direction parameters and combining them with the overall alignment reference, the folded booklets are uniformly adjusted in position, thereby achieving the coordinated forming of the folding shape of each booklet with the overall integrated structure. This results in a smooth unfolding of the integrated structure, a neat appearance, and a stable relative relationship between each booklet.

[0070] 4. In this invention, by setting the pressing position and pressing sequence, and performing pressing treatment on the integrated structure in a predetermined order, the orderly solidification of the binding and folding structure is achieved, resulting in a high flatness of the integrated structure, sufficient release of internal stress, and significantly improved stability after molding.

[0075] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0076] Technical concept:

[0077] In the field of traditional bookmaking, especially in the production of accordion-bound books with complex structures and special binding requirements, existing technologies face numerous challenges in areas such as stitching precision, overall structural stability, handling thickness variations, and quality control. For example, taking the book *Mei Jian* as an example, its unique accordion-bound structure of eight small volumes with a single cover demands extremely high stitching precision and structural stability. Current technology faces several challenges: First, due to the narrow spacing between each volume (less than 2cm), the stitching distance must be highly precise and straight. Even the slightest deviation in the stitching will not only affect the uniformity of the spacing between the volumes, hindering subsequent folding and binding processes, but will also severely impact the overall structural stability and appearance quality of the book.

[0078] Second: With eight booklets sharing the same sheet of paper for linking each book and very little spacing, ensuring the precise relative position of each folded sheet to the booklets is crucial during production. Improper handling of the linking sheet and cover, such as unevenness or dimensional deviations, can easily cause the booklets to shift, resulting in a loose fit between the linking sheet and the booklets. This ultimately leads to a loose overall book structure, failing to achieve the intended use and display effect.

[0079] Third: The thickness of each booklet is inconsistent. How to properly handle this thickness difference during the stitching and folding process is a major challenge. If it cannot be effectively dealt with, the books will be uneven after folding, and the spine will be loose. This will not only affect the appearance of the books, but also reduce their durability and lifespan.

[0080] Fourth: If any mistake occurs during the production process, especially if even a small book has a defect, such as incorrect stitching or uneven folding, the entire book will fail to meet quality standards and must be scrapped. This undoubtedly increases production costs and time significantly, severely impacting production efficiency and economic benefits.

[0081] In this technical solution: to address the first problem, the stitching deviation is detected and corrected in real time during the binding process to ensure that the stitching spacing of each booklet is uniform, thus avoiding any deviation from affecting subsequent binding and folding processes;

[0082] Regarding the second issue: Through a high-precision positioning device and an adaptive adjustment mechanism, the relative positions of all booklets and connecting papers remain consistent during the binding process, avoiding the looseness and misalignment problems commonly found in traditional hand binding.

[0083] Regarding the third issue: a layered folding and progressive binding method was adopted. Through intelligent folding and stitch adjustment technology, it automatically adapts to booklets of different thicknesses, ensuring that the entire book structure is flat and uniform after folding, and avoiding the problem of loose or uneven spines caused by thickness differences.

[0084] Regarding the fourth question: By monitoring the quality status of each step in real time, the system can automatically inspect and correct every key node in the sewing, folding, and binding processes to prevent unqualified books from continuing to flow into the production line.

[0085] To better understand the above technical solutions, the technical solutions of the present invention will be clearly and completely described below in conjunction with embodiments.

[0086] Example 1

[0087] Reference Figures 1-4 In the first embodiment of the present invention, the present invention provides a method for preparing a high-precision accordion-bound multi-volume book, comprising the following steps:

[0088] The cover or connecting medium that serves as the basis for the binding is pre-treated to form a stable binding standard.

[0089] The book block is divided into multiple booklets, and these booklets are placed on the cover or connecting medium in a predetermined order.

[0090] Based on the binding standard, each booklet is bound and positioned separately;

[0091] According to the binding positioning, each booklet is bound and fixed in sequence, so that each booklet is connected to the cover or connecting carrier respectively;

[0092] After each booklet is bound and secured, it is folded into shape.

[0093] After all the booklets have been bound, fixed, and folded, the overall structure is adjusted uniformly.

[0094] The adjusted conjoined structure is then compressed to complete the production of multiple conjoined books.

[0095] Preprocessing the cover or connecting medium includes the following steps:

[0096] Set the position parameters of the binding reference;

[0097] Apply controlled heat pressing or flattening to the cover or connecting carrier;

[0098] The cover or connecting carrier is unfolded and corrected based on the position parameters;

[0099] Determine whether the cover or connecting carrier meets the flatness requirements for binding; if not, perform repeated correction operations.

[0100] The cover or connecting carrier is a sheet structure made of paper or composite material. The sheet structure is used to support multiple booklets and form the overall support for the accordion-bound book. The cover or connecting carrier is a sheet material used to support multiple booklets and serve as the overall binding reference. Pre-treatment is used to release the internal stress in the sheet material and define its planar state.

[0101] Specifically, based on the arrangement of multiple booklets in the unfolded state of the accordion-bound book, the reference position parameters for binding alignment are pre-determined on the cover or connecting carrier. This ensures that the sheet structure always has a unified spatial reference during subsequent processing and binding. The cover or connecting carrier is transformed from a passive load-bearing component in traditional processes into an active binding base with clear reference significance. By pre-locking the binding reference position through parametric methods, the relative position shift of the booklets due to material deformation or human alignment errors during the subsequent binding of multiple books is avoided.

[0102] Secondly, after setting the binding reference position parameters, a controlled hot pressing or flattening treatment is applied to the cover or connecting carrier. Based on the characteristics of the paper or composite material used in the cover or connecting carrier, heat and pressure are applied under controlled conditions to cause the sheet material to undergo shape adjustment under a limited state. Through the action of controlled external force, the internal stress accumulated in the material during production, cutting or storage is released or redistributed, reducing the tendency of the material to warp or spring back during subsequent folding, binding or environmental changes. This fundamentally improves its stability as the overall binding reference, so that the cover or connecting carrier is in a controlled and predictable physical state before entering the correction stage, demonstrating the effect of improving binding reliability at the stress level.

[0103] Subsequently, after hot pressing or flattening, the cover or connecting carrier is unfolded and corrected according to the position parameters of the aforementioned binding reference. This allows the processed sheet structure to unfold according to the set reference parameters, ensuring that its actual unfolded shape is consistent with the preset binding reference. Using the binding reference as a constraint, adjustments are made to any overall offset or uneven unfolding state of the sheet structure. The reference parameters uniformly constrain the planar orientation of the material, ensuring that the cover or connecting carrier meets the requirements of serving as a common binding basis for multiple booklets in terms of geometric relationship. This avoids overall structural inconsistencies caused by unfolding errors during subsequent binding processes.

[0104] Finally, the unfolded and corrected cover or connecting carrier is judged to confirm whether it meets the flatness conditions for binding. If the judgment result shows that it does not meet the requirements, the correction operation is repeated until the flatness conditions for binding are met. By introducing this judgment and repeated correction process, the flatness of the cover or connecting carrier no longer depends on the result of a one-time processing, but gradually tends to stabilize through repeated controlled adjustments, eliminating residual internal stress or local deformation, so that the flatness of the sheet material is limited to a suitable range for binding. By solving the qualification of the binding benchmark as an independent technical problem, the cover or connecting carrier is guaranteed to have stable support and alignment capabilities in subsequent multi-book binding and accordion-style unfolding use.

[0105] Divide the book block into multiple booklets, including the following steps:

[0106] The entire book block is paginated to ensure that the pages are arranged in the intended reading order.

[0107] Based on the overall structural design of the combined book, determine the start and end pages of each booklet;

[0108] Set dividing lines for the book block at the start and end pages;

[0109] The book block is separated along the dividing line, so that the book block is divided into multiple independent booklet units;

[0110] The separated booklet units are aligned with their margins to form a booklet structure that can be bound and folded independently;

[0111] Each booklet unit, after being separated, maintains a continuous page order and is ready to be compiled into a separate booklet.

[0112] Specifically, the page order of the entire book block is first corrected so that each page is physically arranged in the predetermined reading order. By completing the page order correction before the book block is split, the overall structure of the book block has a clear reading logic, thereby avoiding the problem of page misalignment or disordered order in the subsequent separation process, and providing the basic conditions for the booklet to be separated into its own volume.

[0113] Based on the overall structural design of the book, the starting and ending pages of each booklet within the main block are determined, and dividing lines are set at these corresponding starting and ending pages. These dividing lines define the scope of each booklet within the main block, ensuring clear boundaries for each booklet from the initial division stage. This division, combined with the overall structural design, ensures consistency in length and arrangement among the booklets, preventing arbitrary division from affecting the subsequent accordion-like connection. The main block is then separated along these dividing lines, forming multiple independent booklet units. During separation, each booklet unit maintains the continuity of its internal pages, ensuring that each booklet, after being separated from the main block, retains a complete reading order and the conditions to stand alone. This ensures that the booklet units are structurally independent yet maintain coordination and unity within the overall design logic.

[0114] The separated booklet units undergo margin alignment to ensure that the page edges of each booklet are uniform, thus forming a booklet structure suitable for subsequent binding and folding. Margin alignment makes the booklet units more geometrically regular, reducing the adverse effects of uneven edges on binding accuracy and folding effect. During the book block division process, each booklet not only maintains continuous page order after separation but also possesses stable independent structural conditions, thus providing a reliable foundation for the subsequent binding and overall assembly of accordion-bound books.

[0115] To place multiple booklets on a cover or connecting medium, the following steps are included:

[0116] Set the arrangement order of multiple booklets on the cover or connecting medium;

[0117] Place the booklets in the order they are arranged;

[0118] Determine if the placement order of each booklet is consistent with the predetermined order, and trigger an order adjustment operation if they are inconsistent;

[0119] After adjusting the order, confirm that each booklet is correctly positioned and maintains the predetermined spacing from the previous booklet.

[0120] Specifically, first, determine the placement of the booklets based on the overall design to ensure that the accordion-bound books have a unified structure and high operability when unfolded, and determine the arrangement order of the booklets on the cover or connecting carrier. Based on the book design, clarify the position of each booklet on the cover to ensure that the arrangement meets reading needs and maintains consistency;

[0121] According to the set order, place the booklets sequentially on the cover or connecting carrier. During operation, ensure that each booklet is placed in the predetermined position to avoid misalignment and ensure structural stability. Check whether the booklet placement order is consistent with the predetermined order. If a misalignment is found, the system or manual intervention will trigger an adjustment operation to ensure that each booklet is placed in the correct order. After adjustment, confirm that the booklets are correctly positioned and maintain the predetermined spacing from the previous booklet. Check the position and spacing of each booklet to ensure the overall stability and unfoldability of the binding. Through the above steps, ensure that multiple booklets are accurately placed on the cover or connecting carrier, guaranteeing structural precision and the normal use of the accordion binding.

[0122] The booklets are bound and positioned according to the binding standard, including the following steps:

[0123] Set the positioning parameters of each booklet relative to the binding reference;

[0124] The binding position of each booklet is determined based on the positioning parameters;

[0125] Verify the binding position and confirm its consistency with the binding reference.

[0126] If the verification fails, a positioning adjustment operation is triggered to ensure that the binding position of each booklet is correct.

[0127] Specifically, the booklets to be bound are first placed one by one on the cover or connecting carrier, with the binding edge of each booklet facing the binding reference direction. By aligning the binding edge of the booklet with the binding reference, the booklet is restricted in both horizontal and vertical positions, thus initially determining its binding position. According to the preset positioning parameters, the position of the booklet is fine-tuned. This fine-tuning can be done by pushing the edge of the booklet, using positioning baffles, limit blocks, or marking lines, so that the binding edge of the booklet is consistent with the binding reference. At the same time, the spacing between the booklets is controlled to prevent the booklets from being misaligned or shifted left or right before binding.

[0128] After the position adjustment is completed, the position of the current booklet is checked. During the check, the binding edge of the booklet is observed to see if it is aligned with the binding reference, or the distance between the edge of the booklet and the binding reference is measured to determine whether it meets the predetermined binding position requirements. If a deviation in the booklet position is found, the booklet is moved again to align it with the binding reference. When the check result meets the requirements, the booklet is kept in the current position, and the same positioning operation is continued for the next booklet. By aligning and checking one by one, multiple booklets are positioned according to the same binding reference before binding, thereby ensuring that the position of each booklet is consistent and neatly arranged during subsequent binding. The binding position is not based on experience judgment, but is completed by aligning with the binding reference and repeatedly confirming with the check, so that multiple booklets maintain a stable and controllable relative positional relationship during the binding process.

[0129] The booklets are bound and secured sequentially, including the following steps:

[0130] Select the booklets to be bound according to the predetermined binding order;

[0131] Perform the binding and securing operation at the corresponding binding position;

[0132] Determine if the current booklet is bound and secured, and switch to the next booklet if it is.

[0133] During the binding process, it is determined whether the binding process meets the quality standards, and corrective actions are performed if it does not.

[0134] Specifically, the operator selects each booklet one by one according to the overall structure and predetermined binding order of the books, and places them sequentially in the binding area. The selection order can be determined manually or by an automated control system, ensuring that each booklet is bound according to the designed sequence, and performing the binding and securing operation at the corresponding binding position. This operation involves aligning the booklet with the predetermined binding reference and securing it to the cover or connecting carrier mechanically or manually. Common securing methods include needle and thread binding, glue, or other suitable binding techniques. During the securing process, it is crucial to ensure that the binding edge of the booklet is aligned with the binding reference line to prevent misalignment or deviation. The operator then determines whether the binding of the current booklet is complete. This can be done through visual inspection, tactile detection (including light pressing to check for firmness), or automated detection devices including laser positioning and sensor detection. If the binding of the current booklet is complete, the process moves to the next booklet, repeating the binding steps. The entire process ensures that each booklet is securely fixed within the binding area and that the order is not reversed.

[0135] During the binding process, quality standards are assessed by real-time monitoring of the binding status to ensure that each booklet meets the required standards. This includes checking if the booklet is tightly attached to the cover, if the binding edges are neat, and if the binding effect meets the predetermined requirements. If any substandard quality issues are found during the binding process, such as looseness, misalignment, or unevenness, corrective actions are performed. These actions typically involve readjusting the booklet's position or re-fixing it. In automated systems, robotic arms automatically reposition the booklets; in manual operations, the booklet's position needs to be adjusted or the binding needs to be re-fixed. This ensures that the binding quality of each booklet consistently meets the requirements and improves the reliability of the binding process.

[0136] The booklet is folded and shaped, including the following steps:

[0137] Set the booklet's folding direction parameters;

[0138] Perform a folding operation on the bound booklet based on the folding direction parameters;

[0139] Determine whether the folded booklet has formed the predetermined shape, and perform a folding adjustment operation if it has not.

[0140] Specifically, firstly, the folding direction parameters of the booklets need to be set. These parameters specify the folding direction, the position of the fold line, and the size of the folding angle for each booklet during the folding process. The setting of the folding direction parameters is determined based on the book's binding structure, the desired effect after folding, and the final product's appearance and functional requirements. By setting the folding direction, it is ensured that each booklet can unfold correctly after binding, forming a stable and neat folding structure.

[0141] Based on the set folding direction parameters, the bound booklets are folded. Through mechanized or automated equipment, combined with precise control of the folding direction and angle, each booklet is folded along the predetermined folding line. This process can be achieved by using a folding machine or other folding auxiliary equipment, and by adjusting factors such as the pressure, speed, and angle of the booklet to ensure that the booklet can be folded according to the predetermined folding parameters. The folding operation not only ensures the neatness of the booklet structure but also ensures the ease of use after the booklet is unfolded. It is necessary to determine whether the booklet has formed the predetermined shape, which is done by manual inspection or automated equipment. Usually, visual inspection or sensor equipment is used to detect the folding angle and alignment status. If the folded booklet does not achieve the expected shape, including if the folding line is not straight, the angle is inaccurate, or the edges are not neat, a folding adjustment operation will be triggered. The folding adjustment operation includes refolding, adjusting the parameters of the folding machine, or resetting the folding direction parameters to ensure that the folding effect of each booklet meets the predetermined standard.

[0142] Through a real-time monitoring and adjustment mechanism, closed-loop control of folding quality is achieved. Precise shape judgment and quality inspection are performed after each fold to ensure that the folding accuracy of each booklet is within the standard range. When deviations occur, the system automatically implements adjustment measures. This technical mechanism not only improves folding accuracy but also significantly reduces quality fluctuations caused by human factors, ensuring high-standard product output.

[0143] The overall integrated structure was adjusted in a unified manner, including the following steps:

[0144] Set the alignment reference for the overall integrated structure;

[0145] Adjust the overall position of each folded booklet according to the alignment reference;

[0146] Determine if the overall structure meets the alignment requirements, and perform readjustment if it does not.

[0147] Specifically, setting the alignment benchmark for the overall integrated structure refers to the alignment lines, connecting edges, or reference points for aligning multiple booklets with the edges of the cover and connecting carrier. The alignment benchmark can be set through previous design documents or through machine automation systems, allowing each booklet to be positioned according to a unified standard. The overall position of each folded booklet is adjusted based on the alignment benchmark. By fine-tuning the relative position of each booklet, all booklets can be precisely aligned after folding. Tools such as positioning plates, automatic positioning devices, or pressure plates can be used to ensure that the position of each booklet is consistent with the alignment benchmark. The adjustment must not only ensure the alignment of each booklet in the left and right directions, but also ensure the flatness of each booklet in the up and down directions to avoid any deviation.

[0148] To determine whether the overall structure meets the alignment requirements, visual inspection, sensor detection, or mechanical feedback can be used. By measuring the deviation of the relative position of each booklet from the alignment reference, it can be determined whether the overall structure has reached the predetermined alignment accuracy. If the overall structure is found to be not in line with the alignment requirements, it can be done through an automated control system or manual intervention. The automated adjustment method uses the robotic arm, pressure plate, or other positioning device to accurately reposition each booklet, ensuring that the position of all booklets is consistent with the alignment reference again. If manual intervention is used, the operator will manually adjust the position of each booklet until the predetermined alignment standard is reached. This is used to ensure the stability and consistency of the overall structure and avoid book quality problems caused by booklet misalignment or inaccurate alignment.

[0149] By judging the alignment accuracy of the overall structure in real time, deviations can be automatically identified and adjustments can be triggered, reducing the need for manual intervention and improving the automation level of the production process. Compared with traditional manual adjustments, this invention can complete more accurate and efficient adjustments in a short time, ensuring that the quality of the finished books always meets the requirements.

[0150] The process of compressing the one-piece structure includes the following steps:

[0151] Set the clamping position and clamping sequence;

[0152] Perform the clamping operation on the integrated structure according to the clamping sequence;

[0153] Determine whether the compaction process is complete, and confirm the end of the preparation process based on the determination result.

[0154] Specifically, the pressing position and pressing sequence are first set. The pressing position is used to define the area in the integrated structure that needs to be pressured, and the pressing sequence is used to determine the order of pressure application to different areas, so that the pressure can be applied to the integrated structure step by step along the predetermined path. According to the set pressing sequence, the pressing operation is performed on the integrated structure in sequence, so that the pressure is applied to the corresponding position along the thickness direction or folding direction of the integrated structure. By applying pressure step by step, each booklet gradually fits together and tends to be flat during the pressing process, thereby avoiding local warping or structural deformation caused by uneven pressure.

[0155] After the pressing operation is completed, the completion of the pressing process is judged by checking whether the overall flatness of the integrated structure or the pressing state meets the predetermined requirements. The pressing result is confirmed when the judgment result shows that the integrated structure has reached the set pressing state, and the pressing process is confirmed to be completed. The pressing process, through the clear setting of the pressing position and pressing sequence, allows the pressure to be transmitted in an orderly manner in the integrated structure, and the structural state formed during the binding and folding process is solidified. Through the sequential pressing method, a stable mutual constraint relationship is formed between the booklets, thereby improving the overall forming stability and consistency of the integrated structure.

[0156] The binding and positioning of each booklet based on the binding standard also includes the following steps:

[0157] Before binding and positioning, the edges of each booklet already set on the cover or connecting carrier are aligned and corrected to unify the relative initial position of each booklet;

[0158] During the binding and positioning process, the position of each booklet relative to the binding reference is checked in real time.

[0159] After binding and positioning are completed, the consistency of the binding and positioning results of each booklet is confirmed. If any inconsistency is confirmed, the binding and positioning steps are repeated for the corresponding booklet.

[0160] Specifically, edge alignment correction is performed on each booklet already set on the cover or connecting carrier. Through precise alignment devices or manual adjustment, the initial position of each booklet relative to the cover or connecting carrier is ensured to be uniform, avoiding subsequent positioning errors caused by initial deviations. Edge alignment correction ensures that the edges of all booklets are aligned with the binding baseline, providing a reliable starting point for accurate binding.

[0161] Please see Figure 4During the binding and positioning process, the position of each booklet relative to the binding reference is checked in real time. This step uses an automated detection system, including sensors, laser positioning or optical detection, to monitor the deviation of each booklet's position from the binding reference in real time. Through positioning verification, it is ensured that each booklet can be accurately positioned according to the binding reference, avoiding binding position deviation caused by human error or equipment deviation.

[0162] After binding and positioning are completed, the consistency of the binding and positioning results of each booklet is confirmed. This is done by verifying whether all booklets are positioned under the unified standard of binding reference. If any booklet is found to be inconsistent in positioning, i.e., if there is a deviation or misalignment, a repositioning step will be triggered to rebind and position the problematic booklet to ensure that the binding position of all booklets is completely consistent.
