Description

Technical Field

[0001] This application relates to the field of printing and binding technology, and in particular to an adaptive book-sticking assembly machine and method. Background Technology

[0002] With the large-scale development of the printing and publishing and notebook manufacturing industries, the market demand for paper products such as hardcover books, brochures, and customized notebooks continues to increase. Book sticker assembly is the core process in the production of such products. Its core is to accurately attach and fix book stickers with different functions such as cover stickers and inner page stickers through gluing and pressing. The production efficiency, attachment accuracy, and quality control capabilities of this process directly determine the production capacity, yield rate, and market competitiveness of the finished products.

[0003] Currently, book sticker bonding production in the industry is mainly divided into two categories: manual production mode and semi-automated production mode. In the manual production mode, everything from book sticker feeding, content matching and verification, glue application, stacking and pressing to finished product collection is done manually. This not only results in extremely low production efficiency and high labor intensity, but also easily leads to visual fatigue during manual verification, causing quality problems such as mismatched book stickers, missing stickers, and reversed page numbers. The consistency of the finished products is extremely poor, making it impossible to meet the needs of large-scale production. Summary of the Invention

[0004] This application provides an adaptive book sticker bonding assembly machine and its testing method, aiming to solve the industry dilemma of low efficiency, low yield and high dependence on manual labor in book sticker bonding production.

[0005] In a first aspect, embodiments of this application provide an adaptive book sticker bonding and assembly method, applied to the controller of an adaptive book sticker bonding and assembly machine. The adaptive book sticker bonding and assembly machine further includes a frame, a belt conveyor mechanism, a first lifting and palletizing mechanism, a second lifting and palletizing mechanism, a first transfer mechanism, a second transfer mechanism, a dispensing mechanism, a pressing mechanism, and a detection device; the method includes: The first and second lifting and stacking mechanisms are controlled to support the stacked first and second book stickers respectively. After the top book sticker is removed, the book stickers are lifted level by level to maintain a constant material picking height. The first transfer mechanism is controlled to transfer the first book sticker to the glue dispensing station of the belt conveyor mechanism. The detection device is driven to perform content recognition and verification on the first book sticker. After the content recognition and verification is passed, the glue dispensing mechanism is controlled to apply glue to the preset position of the first book sticker. Then, the belt conveyor mechanism is controlled to transport the glued first book sticker to the pressing station. The second transfer mechanism is controlled to transfer the second book sticker to the pressing station and stack it on top of the first book sticker. The detection device is driven to perform content matching verification on the second book sticker. After the content matching verification is passed, the pressing mechanism is controlled to press the stacked book stickers to complete the book sticker bonding assembly.

[0006] In some embodiments, the pallet plates corresponding to the first and second lifting palletizing mechanisms each include two independent placement areas arranged one after the other along the conveying direction of the belt conveyor mechanism; the control of the first and second lifting palletizing mechanisms to support the stacked first and second book labels respectively includes: controlling the two independent placement areas corresponding to the first lifting palletizing mechanism to support the stacked first book labels respectively, and controlling the two independent placement areas corresponding to the second lifting palletizing mechanism to support the stacked second book labels respectively.

[0007] In some embodiments, the step of gradually raising the bookplates after the top layer of bookplates is removed to maintain a constant picking height includes: acquiring the picking status of the top layer of bookplates in the corresponding placement areas of the first lifting and stacking mechanism and the second lifting and stacking mechanism; when it is detected that the top layer of bookplates in the corresponding placement area has been removed, controlling the drive motor of the corresponding lifting and stacking mechanism to drive the screw to rotate, causing the stacking plate to rise vertically along the guide shaft by a distance equal to the thickness of a bookplate, so that the top layer of the remaining bookplates in the corresponding placement area always maintains a preset constant picking height.

[0008] In some embodiments, controlling the first transfer mechanism to transfer the first book label to the dispensing station of the belt conveyor mechanism includes: controlling the cylinder of the first transfer mechanism to drive the transfer plate to move linearly along the guide seat, pushing the first book label on the uppermost layer of the corresponding placement area of ​​the first lifting and stacking mechanism to move towards the dispensing station; during the pushing process, the transfer posture of the first book label is corrected by the guide slope of the guide ribs correspondingly provided on the frame, and the first book label is smoothly pushed to the preset position of the dispensing station of the belt conveyor mechanism.

[0009] In some embodiments, the driving detection device performs content recognition verification on the first book sticker, including: controlling the industrial camera of the detection device to capture a surface image of the first book sticker, extracting key feature information from the image, the key feature information including at least page numbers and barcodes; comparing the extracted key feature information with a pre-stored standard book sticker feature template, determining whether the content and model of the first book sticker meet the preset assembly requirements, and generating a corresponding content recognition verification result.

[0010] In some embodiments, the step of controlling the dispensing mechanism to apply glue to a preset position of the first book sticker after the content recognition verification is passed, and then controlling the conveyor belt mechanism to transport the glued first book sticker to the pressing station, includes: after receiving the result that the content recognition verification of the first book sticker is passed, controlling the drive motor of the dispensing mechanism to drive the screw to rotate, driving the glue gun on the mounting plate to move along the conveying direction of the conveyor belt mechanism, and applying glue to the specified position of the first book sticker according to the preset glue application path; after the glue application is completed, controlling the servo motor of the conveyor belt mechanism to drive the conveyor belt to run, and accurately transporting the glued first book sticker to the preset position of the pressing station.

[0011] In some embodiments, controlling the second transfer mechanism to transfer the second book sticker to the pressing station and stack it on top of the first book sticker includes: controlling the cylinder of the second transfer mechanism to drive the transfer plate to move linearly along the corresponding guide seat, pushing the second book sticker at the top of the corresponding placement area of ​​the second lifting and stacking mechanism to move towards the pressing station; correcting the transfer posture of the second book sticker by the guide slope of the corresponding guide rib during the pushing process, and smoothly pushing the second book sticker to the pressing station and stacking it directly above the first book sticker that has been glued.

[0012] In some embodiments, the driving detection device performs content matching verification on the second book sticker, including: controlling the industrial camera of the detection device to capture a surface image of the second book sticker, extracting key feature information from the image, the key feature information including at least page numbers and barcodes; performing a dual comparison between the extracted key feature information of the second book sticker and the feature information of the corresponding stacked first book sticker and a pre-stored pairing assembly standard, determining whether the second book sticker and the first book sticker are a matching assembly pair, and generating a corresponding content matching verification result.

[0013] In some embodiments, the step of controlling the pressing mechanism to press the stacked book stickers after the content matching verification is passed, thereby completing the book sticker assembly, includes: after receiving the result that the content matching verification of the second book sticker is passed, controlling the drive motor of the pressing mechanism to drive the screw to rotate, causing the pressing component to descend vertically to a preset pressing position, applying a preset pressure to the stacked first and second book stickers and maintaining a preset pressure holding time; after the pressure holding is completed, controlling the pressing component to rise and reset, completing the book sticker assembly, and then controlling the belt conveyor mechanism to transport the assembled book stickers to the unloading guide plate to complete the automatic unloading.

[0014] Secondly, this application provides an adaptive book sticker bonding and assembly machine, including a controller, a frame, a belt conveyor mechanism, a first lifting and palletizing mechanism, a second lifting and palletizing mechanism, a first transfer mechanism, a second transfer mechanism, a dispensing mechanism, a pressing mechanism, and a detection device; wherein the controller is used to implement the method provided in any embodiment of this application.

[0015] This invention enables continuous and automated feeding of book stickers. By controlling two sets of lifting and stacking mechanisms to raise the book stickers step by step after they are taken away, the feeding height is kept constant. This eliminates the need for frequent manual stops for adjustment and completely solves the problems of feeding failure and book sticker misalignment caused by changes in feeding height in existing technologies. It ensures the continuity and stability of feeding and significantly reduces the intensity of manual labor.

[0016] It also achieves collaborative closed-loop control of the entire book-sticking process. The controller coordinates the entire process of feeding, identification and verification, dispensing and pressing, integrating the scattered processes into a complete automated production line. There is no need for manual handling of materials, eliminating waiting and material accumulation between processes, greatly shortening the production cycle and improving overall production efficiency.

[0017] It also enables pre-emptive control of book sticker quality, eliminating mislabeling and omissions at the source. Content recognition and matching verification are completed simultaneously during book sticker transfer. Subsequent processes are only executed after verification, achieving early interception of defective products. This avoids material waste and rework costs caused by post-processing inspections in existing technologies, significantly reducing the defect rate and improving the consistency of finished product quality.

[0018] It also achieves fully automated anomaly control, improving production stability and safety. Through closed-loop control, it directly triggers a shutdown alarm when an anomaly is detected, avoiding waste caused by abnormal booklets entering subsequent processes. It does not require real-time manual monitoring and can meet the needs of large-scale, high-precision production, making it extremely valuable for industry promotion.

[0029] With the large-scale development of the printing and publishing and notebook manufacturing industries, the market demand for paper products such as hardcover books, brochures, and customized notebooks continues to increase. Book sticker assembly is the core process in the production of such products. Its core is to accurately attach and fix book stickers with different functions such as cover stickers and inner page stickers through gluing and pressing. The production efficiency, attachment accuracy, and quality control capabilities of this process directly determine the production capacity, yield rate, and market competitiveness of the finished products.

[0030] Currently, book sticker bonding production in the industry is mainly divided into two categories: manual production mode and semi-automated production mode. In the manual production mode, everything from book sticker feeding, content matching and verification, glue application, stacking and pressing to finished product collection is done manually. This not only results in extremely low production efficiency and high labor intensity, but also easily leads to visual fatigue during manual verification, causing quality problems such as mismatched book stickers, missing stickers, and reversed page numbers. The consistency of the finished products is extremely poor, making it impossible to meet the needs of large-scale production.

[0031] In existing semi-automated production models, the industry generally adopts a decentralized, single-machine operation approach, where each process is completed by an independent feeding machine, gluing machine, and pressing machine, with manual material handling and transfer between processes. While this model can reduce labor intensity to some extent, it still suffers from several unresolved technical drawbacks: First, the book sticker feeding process often uses a fixed hopper structure. As the book stickers are picked up, their height continuously decreases, requiring frequent manual stops to adjust the hopper height. This makes it impossible to achieve automatic, constant compensation for the picking height, easily leading to picking failures and book sticker misalignment, hindering continuous automated feeding and restricting the overall production cycle. Second, the decentralized process layout requires manual material handling, increasing labor costs. Multiple transfers can easily cause book sticker misalignment, surface damage, and folded corners. Furthermore, significant waiting time exists between processes, limiting production efficiency and preventing continuous production throughout the entire process. Third, the quality control of existing semi-automated equipment is severely lacking. The existing equipment suffers from several drawbacks. First, the matching and verification of book sticker content still relies on manual sampling, which can only be done after the finished product is completed. It cannot intercept problems during the book sticker application process. Once a book sticker is mismatched or the content is incorrect, the finished product must be reworked or even scrapped. This not only significantly increases production costs and causes serious waste of materials such as glue and paper, but also fails to fundamentally eliminate quality accidents such as mis-application and omission. Second, the existing equipment only has simple action sequences between its processes, which cannot achieve full-process coordinated control. It cannot adjust the actions of subsequent processes based on the results of previous processes. Even if abnormal situations such as book sticker mismatch or material feeding failure occur, the equipment will continue to perform glue application and pressing actions, resulting in unnecessary material waste. At the same time, abnormal situations cannot be alerted and stopped in real time, resulting in poor production stability and safety.

[0032] Most existing optimizations and improvements to address the aforementioned defects only involve localized adjustments to the mechanical structure of a single process, such as optimizing the uniformity of glue application or improving the pressure adjustment method of the pressing mechanism. These improvements do not address the core pain points of continuous automatic feeding, pre-verification of book sticker content, and closed-loop linkage control of the entire process from the perspective of collaborative control logic. Nor have they formed a complete technical solution that can simultaneously solve all the aforementioned defects, resulting in the industry's book sticker bonding production remaining trapped in a predicament of low efficiency, low yield, and high reliance on manual labor.

[0033] Please see Figures 1 to 6The present invention provides a book sticker assembly machine for automatically assembling different book stickers (e.g., cover stickers or inner page stickers consisting of multiple pages) together. The book sticker assembly machine includes: a frame 100, a belt conveyor mechanism 200, a first lifting and stacking mechanism 300, a second lifting and stacking mechanism 400, a first transfer mechanism 500, a second transfer mechanism 600, an adhesive dispensing mechanism 700, a pressing mechanism 800, and a detection device 900.

[0034] The frame 100, constructed from welded or assembled profiles and plates, forms the structural foundation of the entire equipment. Along the material flow direction, the frame 100 is equipped with a dispensing station 110 and a pressing station 120.

[0035] The belt conveyor mechanism 200 is mounted on the frame 100. Its conveyor belt surface is used to support the book stickers and is driven by a servo motor. It can accurately transfer the book stickers between the dispensing station 110 and the pressing station 120. The dispensing station 110 and the pressing station 120 are both located on the belt conveyor mechanism 200, that is, the book stickers can be dispensed and pressed on the surface of the conveyor belt.

[0036] The first lifting and stacking mechanism 300 is used to stack and store the first book stickers 360 to be pasted, and to lift the first book stickers 360 step by step according to the removal of the first book stickers 360; the second lifting and stacking mechanism 400 is arranged next to the first lifting and stacking mechanism 300, and is used to stack and store the second book stickers 410 to be pasted, and to lift the second book stickers 410 step by step according to the removal of the second book stickers 410; the first lifting and stacking mechanism 300 and the second lifting and stacking mechanism 400 are installed side by side on one side of the frame 100. The first lifting and stacking mechanism 300 is used to stack the first book stickers 360, and the second lifting and stacking mechanism 400 is used to stack the second book stickers 410. Both have automatic lifting and stacking functions. When the top book sticker is removed, the mechanism will automatically rise by the thickness of one book sticker to keep the material picking height constant.

[0037] The first transfer mechanism 500 is disposed above or to the side of the first lifting and palletizing mechanism 300, and is used to grab the first book sticker 360 from the first lifting and palletizing mechanism 300 and move it to the dispensing station 110. Thus, the first transfer mechanism 500 spans between the first lifting and palletizing mechanism 300 and the dispensing station 110, and its function is to push or grab the topmost first book sticker 360 on the first lifting and palletizing mechanism 300 onto the dispensing station 110 of the belt conveyor mechanism 200.

[0038] The second transfer mechanism 600 is disposed above or to the side of the second lifting and palletizing mechanism 400, and is used by the second lifting and palletizing mechanism 400 to grab the second book sticker 410 and move it to the pressing station 120 respectively; similarly, the second transfer mechanism 600 spans between the second lifting and palletizing mechanism 400 and the pressing station 120, and its function is to transfer the second book sticker 410 on the second lifting and palletizing mechanism 400 to the pressing station 120, so that the second book sticker 410 is placed above the first book sticker 360 that has been glued.

[0039] The dispensing mechanism 700 is set on the dispensing station 110 and is used to dispense glue onto the first book sticker 360 conveyed by the first transfer mechanism 500. The dispensing mechanism 700 is installed at the dispensing station 110 and includes at least one dispensing gun 730, which can apply glue evenly or in a specific pattern to a designated position of the first book sticker 360 that arrives at the station according to a preset program.

[0040] The pressing mechanism 800 is set on the pressing station 120 and is used to press the second book sticker 410 conveyed by the second transfer mechanism 600. The pressing mechanism 800 is installed at the pressing station 120 and includes a pressing member 820 that can move up and down. When the second book sticker 410 is placed on the first book sticker 360, the pressing member 820 presses down and applies a certain pressure and time to make the two stick together tightly.

[0041] An inspection device 900, mounted on the frame 100, is used to visually inspect the contents of the first bookplate 360 ​​and the second bookplate 410. The inspection device 900 typically consists of one or more industrial cameras, mounted near the first transfer mechanism 500 and the second transfer mechanism 600. It is used to capture and identify key information (such as page numbers and barcodes) on the bookplates before or during transfer, and sends the data to the controller 1100 for analysis and comparison to ensure that the two types of bookplates to be assembled are correctly matched.

[0042] Through the above technical solution, the book sticker assembly machine of the present invention systematically integrates a lifting and palletizing mechanism, a transfer mechanism, a glue dispensing mechanism 700, a pressing mechanism 800, and a visual inspection device 900 around a belt conveyor mechanism 200, constructing a fully automated production line from automatic feeding, content recognition, precise glue dispensing, accurate pressing to finished product output. This setup fundamentally changes the traditional decentralized, manually-intervened production mode, eliminating waiting times and material turnover between processes, and improving the efficiency of book sticker assembly. Simultaneously, the introduction of the visual inspection device 900 verifies the book sticker content at the assembly source, eliminating quality accidents such as incorrect or missing stickers from a hardware perspective, and improving the pass rate and consistency of the final book product.

[0043] The following detailed description of the construction details of each component is provided in conjunction with specific embodiments.

[0044] Please refer to Figure 1 and Figure 3 In this embodiment, the first lifting and palletizing mechanism 300 includes a first support 310, a palletizing plate 320, a first drive motor 330, and a first screw 340. The first support 310 is securely mounted on the frame 100. The palletizing plate 320 is slidably mounted on the first support 310 in the vertical direction through the cooperation of a slider and a guide rail. A first threaded hole 321 is provided through the central area of ​​the palletizing plate 320. The first drive motor 330 (e.g., a stepper motor or a servo motor) is fixed to the top or bottom of the first support 310, and its output shaft is connected to one end of the first screw 340. The other end of the first screw 340 is rotatably mounted on the bottom of the first support 310 through a bearing seat. The threaded portion of the first screw 340 passes through the first threaded hole 321 of the palletizing plate 320, forming a screw-nut transmission pair. When the first drive motor 330 receives a command from the controller 1100 and rotates, it can drive the palletizing plate 320 to rise or fall precisely.

[0045] Furthermore, to ensure the absolute stability of the pallet 320 during the lifting process, the first lifting and palletizing mechanism 300 also includes two guide shafts 350. These two guide shafts 350 are vertically fixed to the first bracket 310 and symmetrically distributed on both sides of the first screw 340. Correspondingly, the pallet 320 has two sliding holes 322 that mate with the guide shafts 350. During the lifting process, the guide shafts 350 guide and limit the pallet 320, effectively preventing any tilting or twisting and ensuring the neatness of the stacked book tags.

[0046] Please continue to refer to Figure 1 and Figure 3 To improve the feeding, gluing, and pressing efficiency of the book sticker assembly machine, the pallet 320 is designed with two independent placement areas 323. These two placement areas 323 are arranged back-to-back along the conveyor belt mechanism 200. Each placement area 323 can independently stack a stack of first book stickers 360. The first transfer mechanism 500 can simultaneously transfer the first book stickers 360 in both placement areas 323 to the gluing station 110. At the same time, the gluing mechanism 700 can simultaneously apply gluing to the two first book stickers 360 located at the gluing station 110. Correspondingly, when the two first book stickers 360 move to the pressing station 120, the second transfer mechanism 600 can also simultaneously drive the second book stickers 410 to be transferred to their respective second book stickers 410. Similarly, the pressing mechanism 800 synchronously presses the book stickers located at the pressing station 120. This can improve assembly efficiency and speed up the production assembly process.

[0047] It should be noted that the second lifting and palletizing mechanism 400 is similar to the first lifting and palletizing mechanism 300, and will not be described in detail here.

[0048] Please refer to Figure 1 and Figure 4 In this embodiment, the first transfer mechanism 500 includes a guide seat 510 fixed on the frame 100, a cylinder 520 installed at one end of the guide seat 510, and a transfer plate 530 connected to the telescopic rod of the cylinder 520. The transfer plate 530 slides in cooperation with the linear guide rail on the guide seat 510. In the initial state, the transfer plate 530 is located on the side of the first book sticker 360 facing away from the dispensing station 110. When loading is required, the telescopic rod of the cylinder 520 extends, driving the transfer plate 530 to move forward in a straight line along the guide seat 510. The transfer plate 530 contacts the side of the uppermost first book sticker 360 on the first lifting and stacking mechanism 300 and smoothly pushes it away from the stacking plate 320, sliding it into the dispensing station 110 of the belt conveyor mechanism 200. It should be noted that the second transfer mechanism 600 uses a similar mechanism to the first transfer mechanism 500, and will not be described in detail here.

[0049] To ensure the book stickers don't go astray during the push process, please refer to... Figure 1 and Figure 7 The frame 100 is equipped with two guide ribs 130. These two guide ribs 130 are located at the two exit positions on both sides of the first lifting and stacking mechanism 300. Each guide rib 130 has a guide ramp 131 on the side facing the stacking plate 320. When the transfer plate 530 pushes the book label forward, the two edges of the book label will naturally contact the guide ramps 131 on both sides. Even if there is a slight deviation in the initial position, it can be automatically corrected under the guidance of the guide ramps 131, and finally enter the belt conveyor mechanism 200 with the correct posture and position.

[0050] Please refer to Figure 1 and Figure 5The dispensing mechanism 700 includes a second bracket 710, a mounting plate 720, a dispensing gun 730, a glue tank 740, a second drive motor 750, and a second screw 760. The second bracket 710 spans above the dispensing station 110. The mounting plate 720 is slidably mounted on the second bracket 710 via a slider, with its sliding direction parallel to the conveying direction of the belt conveyor mechanism 200. The dispensing gun 730 is vertically mounted on the mounting plate 720, with its dispensing nozzle aligned with the spine of the book sticker below. The mounting plate 720 has a second threaded hole 721. The second drive motor 750 is fixed to one end of the second bracket 710, and its output shaft is connected to the second screw 760. The other end of the second screw 760 is rotatably mounted on the other end of the second bracket 710 and threadedly connected to the second threaded hole 721 of the mounting plate 720. Driven by the second drive motor 750, the movement of the dispensing gun 730 along the belt direction can be precisely controlled, thereby achieving glue application at different positions. The glue tank 740 is connected to the glue gun 730 via piping and a delivery pump (not shown in the figure) to provide a stable and continuous supply of glue.

[0051] Please refer to Figure 1 and Figure 6 The pressing mechanism 800 includes a third support 810, a pressing component 820, a third drive motor 830, and a third screw 840. The third support 810 is fixedly installed above the pressing station 120. The pressing component 820 is slidably mounted on the third support 810, with a flat pressure plate at its bottom for contacting the book label. The pressing component 820 has a third threaded hole 821. The third drive motor 830 is fixed to the top of the third support 810, and its output shaft is connected to the third screw 840. The other end of the third screw 840 is rotatably connected to the bottom of the third support 810 and threadedly engages with the third threaded hole 821 of the pressing component 820. When the third drive motor 830 rotates forward, it drives the pressing component 820 to descend smoothly, applying pressure to the book label below for pressing. When the third drive motor 830 rotates in reverse, it drives the pressing component 820 to rise and reset. This configuration allows for precise control of the pressing stroke and pressure by controlling the number of rotations and torque of the motor.

[0052] Please refer to Figure 1 The book sticker bonding and assembly machine also includes a feeding guide plate 1000, which is located at the end of the belt conveyor mechanism 200, downstream of the pressing station 120. The feeding guide plate 1000 is a sheet metal part with an inclined surface. After the book stickers are pressed, they continue to move forward with the belt. When they reach the feeding guide plate 1000, they slide down the inclined surface under the action of gravity and finally fall neatly into the collection basket or flow into the next process, realizing the automatic collection of finished products.

[0053] Please refer to Figure 1To achieve automated control of the entire book-attachment assembly machine, a controller 1100 is also installed on the frame 100. The controller 1100 can be a programmable logic controller (PLC), a microcontroller, or other control device capable of controlling electrical components; no specific limitation is made here. It has a pre-set control program. The controller 1100 is electrically connected via wires to the drive motors of the belt conveyor mechanism 200, the first drive motor 330, the drive motor of the second lifting and stacking mechanism 400, the solenoid valve of the cylinder 520 of the first transfer mechanism 500, the drive element of the second transfer mechanism 600, the second drive motor 750, the third drive motor 830, and the camera of the detection device 900.

[0054] When the book sticker bonding and assembly machine is working, the controller 1100 coordinates the actions of each component: First, it controls the first transfer mechanism 500 to send the first book sticker 360 to the glue dispensing station 110, and at the same time controls the detection device 900 to identify the first book sticker 360; after the identification is correct, it controls the glue dispensing mechanism 700 to dispense glue; then the belt conveyor mechanism 200 sends the glued first book sticker 360 to the pressing station 120; at the same time, the second transfer mechanism 600 sends the second book sticker 410 to the pressing station 120, and after the detection device 900 identifies it correctly, the controller 1100 controls the pressing mechanism 800 to press down to complete the bonding; finally, the finished product is output by the unloading guide plate 1000. If the detection device 900 identifies a book sticker with incorrect content, the controller 1100 immediately issues an alarm and stops the machine, waiting for manual handling.

[0055] To solve the above problem, please refer to Figure 8 This application provides an adaptive book sticker bonding and assembly method, applicable to, for example... Figures 1 to 7 The controller of the adaptive book-sticking assembly machine provided in the corresponding embodiment.

[0056] The provided adaptive book sticker bonding and assembly method includes steps S101 to S103. Details are as follows: Step S101. Control the first lifting and stacking mechanism and the second lifting and stacking mechanism to support the stacked first book sticker and the second book sticker respectively. After the top book sticker is removed, lift the book sticker level by level to maintain a constant material picking height.

[0057] Specifically, the core of this step is to solve the industry pain points of the existing fixed hopper structure, which requires frequent manual stops to adjust the hopper height, resulting in material retrieval failures and book sticker grabbing misalignment. By using the automatic lifting and palletizing mechanism to compensate for the lifting height, the material retrieval height can be kept constant, ensuring the continuity, stability and automation of book sticker feeding, eliminating manual feeding intervention and laying the foundation for continuous production of the whole machine.

[0058] During the equipment initialization phase, the controller first sends a reset command to the first and second lifting and stacking mechanisms, controlling the corresponding drive motors to rotate the screws, causing the stacking plates to descend along the guide shafts on both sides to the initial loading position. The operator places the first layer of book stickers to be pasted on the stacking plate of the first lifting and stacking mechanism, and the second layer of book stickers to be pasted on the stacking plate of the second lifting and stacking mechanism. Subsequently, the controller controls the drive motors to lift the stacking plates, so that the upper surface of the top layer of book stickers reaches the preset constant picking height, completing the loading preparation.

[0059] During equipment operation, the controller acquires the material handling signals of the first and second transfer mechanisms in real time and monitors the material handling status of each palletizing mechanism. When it is detected that the first book sticker on the top layer of the first lifting palletizing mechanism has been successfully removed by the first transfer mechanism, the controller immediately sends a precise control command to the first drive motor of the first lifting palletizing mechanism to drive the first screw to rotate. Through the screw and nut transmission pair, the palletizing plate is lifted vertically upward by a distance equal to the thickness of a book sticker along the guide shafts symmetrically distributed on both sides, so that the top surface of the remaining first book sticker is always maintained at the preset constant material handling height.

[0060] Similarly, when the controller detects that the second book sticker on the top layer of the second lifting and palletizing mechanism has been successfully taken away by the second transfer mechanism, it synchronously controls the drive motor of the second lifting and palletizing mechanism to raise the corresponding palletizing plate by the thickness of one book sticker, maintaining the material picking height of the second book sticker at a constant level. No manual stopping or adjustment is required throughout the process, achieving continuous automatic feeding.

[0061] Step S102. Control the first transfer mechanism to transfer the first book sticker to the glue dispensing station of the belt conveyor mechanism, and synchronously drive the detection device to perform content recognition and verification on the first book sticker. After the content recognition and verification is passed, control the glue dispensing mechanism to complete the glue application at the preset position of the first book sticker, and then control the belt conveyor mechanism to transport the glued first book sticker to the pressing station.

[0062] Specifically, the core of this step is to achieve automated and precise transfer of the first book sticker, pre-verification of content, precise glue application, and precise flow between workstations. It constructs a closed-loop control logic of "verification-execution" to solve the problems of book sticker damage and displacement caused by manual handling in existing technologies, errors and omissions in manual verification, inability to intercept errors in post-process inspection, and long waiting time between processes. It intercepts erroneous book stickers at the source, avoids waste of materials such as glue and paper, and achieves seamless connection between processes.

[0063] After the controller confirms that the material picking height of the first lifting and palletizing mechanism is constant, it sends a control command to the cylinder solenoid valve of the first transfer mechanism, controlling the cylinder extension rod to extend and drive the transfer plate to move forward in a straight line along the linear guide rail of the guide seat, pushing the first book sticker on the top layer of the first lifting and palletizing mechanism towards the dispensing station. During the pushing process, the guide slopes of the two guide ribs corresponding to the frame automatically correct the posture of the two sides of the first book sticker, eliminating the slight deviation and angle deflection of the initial position, ensuring that the first book sticker is pushed smoothly to the preset positioning position of the dispensing station of the belt conveyor mechanism with a precise posture and position. At this time, the conveyor belt of the belt conveyor mechanism is in a locked state, fixing the position of the first book sticker.

[0064] Synchronous content recognition verification involves the controller immediately activating a detection device (industrial camera) installed near the first transfer mechanism during or after the first bookplate is transferred to the dispensing station. This device captures a complete surface image of the first bookplate, extracts key features such as page numbers and barcodes, and compares this information with a pre-stored standard bookplate feature template. The controller quickly determines whether the content and model of the first bookplate meet the preset requirements for this assembly, generates a content recognition verification result, and sends it back to the controller. If the verification fails, the controller immediately triggers an audible and visual alarm and stops the entire machine, prohibiting subsequent dispensing actions until manual intervention is required. If the verification passes, subsequent processes are allowed to proceed.

[0065] After receiving the verification result, the controller immediately sends a control command to the dispensing mechanism to control the second drive motor of the dispensing mechanism to start, drive the second screw to rotate, and drive the mounting plate to move along a path parallel to the belt conveyor direction through the lead screw and nut transmission pair. The dispensing gun mounted vertically on the mounting plate moves synchronously. The glue tank provides a stable glue supply to the dispensing gun through pipelines and delivery pumps. The dispensing gun completes the uniform application of glue to the designated position of the first book sticker according to the preset glue application path and glue application parameters. After the glue application is completed, the dispensing mechanism is controlled to reset.

[0066] After the glue application is completed, the controller sends a control command to the servo motor of the belt conveyor mechanism to drive the conveyor belt to operate precisely. The first book sticker with glue applied is smoothly and accurately transported from the glue application station to the preset positioning position of the downstream pressing station. The conveyor belt is locked again, completing the entire process flow of the first book sticker.

[0067] Step S103. Control the second transfer mechanism to transfer the second book sticker to the pressing station and stack it on top of the first book sticker, and drive the detection device to perform content matching verification on the second book sticker. After the content matching verification is passed, control the pressing mechanism to press the stacked book stickers to complete the book sticker bonding assembly.

[0068] Specifically, the core of this step is to achieve automated and precise transfer of the second book sticker, pairing and verification with the first book sticker, precise pressing and bonding, and automatic unloading of the finished product, completing the collaborative closed-loop control of the entire process. This solves the problems of high mismatch rate, insufficient pressing accuracy, scattered and unlinked processes, and poor consistency of finished product quality in existing technologies, completely eliminating quality accidents such as mis-bonding and missing bonding, and realizing fully automated and continuous production of the entire book sticker bonding process.

[0069] Precise transfer and stacking control: After the controller confirms that the first book sticker after dispensing has accurately reached the pressing station and completed its positioning, it simultaneously sends control commands to the second lifting and stacking mechanism and the second transfer mechanism. After confirming that the material picking height of the second lifting and stacking mechanism is constant, it controls the cylinder extension rod of the second transfer mechanism to extend, driving the corresponding transfer plate to move forward in a straight line along the guide seat, pushing the uppermost second book sticker of the second lifting and stacking mechanism to move towards the pressing station. During the pushing process, the guide slope of the guide ribs set on the frame automatically corrects the transfer posture of the second book sticker, ensuring that the second book sticker is pushed smoothly to the pressing station with a precise posture and accurately stacked directly above the first book sticker that has been dispensed, completing the pre-assembly and pairing of the two layers of book stickers.

[0070] Synchronous content matching verification involves the controller immediately activating the industrial camera of the detection device during the transfer of the second bookplate to the lamination station or after stacking. The camera captures a complete surface image of the second bookplate, extracting key feature information such as page numbers and barcodes. This image is then compared with pre-stored pairing assembly standards and with the feature information of the corresponding stacked first bookplate. This precise determination of whether the second and first bookplates are a pre-set matching assembly pair generates a content matching verification result, which is fed back to the controller. If the verification fails, the controller immediately triggers an audible and visual alarm and stops the entire machine, prohibiting subsequent lamination operations. If the verification passes, the subsequent lamination process is allowed.

[0071] After receiving the successful verification result, the controller immediately sends a control command to the third drive motor of the pressing mechanism, driving the third screw to rotate forward. Through the lead screw and nut transmission pair, the pressing component descends vertically and smoothly along the third support until it reaches the preset pressing position. A preset pressure is applied to the stacked first and second book covers, and this pressure is maintained for a preset holding time, allowing the two layers of book covers to bond tightly with adhesive. After the holding time ends, the controller controls the third drive motor to rotate in the reverse direction, causing the pressing component to rise vertically and reset, completing the book cover bonding assembly.

[0072] After the automatic unloading control of finished products is completed through pressing and resetting, the controller controls the servo motor of the belt conveyor mechanism to start again, driving the conveyor belt to transport the assembled finished book stickers to the unloading guide plate at the end of the belt conveyor. Under the action of gravity, the finished book stickers slide down the inclined slope of the unloading guide plate and fall neatly into the collection basket or flow into the downstream process, completing the automatic unloading and collection of finished products. This completes the entire process of a single book sticker bonding and assembly.

[0073] In some embodiments, the pallet plates corresponding to the first and second lifting palletizing mechanisms each include two independent placement areas arranged one after the other along the conveying direction of the belt conveyor mechanism; the control of the first and second lifting palletizing mechanisms to support the stacked first and second book labels respectively includes: controlling the two independent placement areas corresponding to the first lifting palletizing mechanism to support the stacked first book labels respectively, and controlling the two independent placement areas corresponding to the second lifting palletizing mechanism to support the stacked second book labels respectively.

[0074] The core of this embodiment is the pallet structure design with dual independent placement areas, which enables simultaneous material feeding and operation at two workstations. Without increasing the equipment footprint, it can significantly improve the overall production efficiency, solve the problems of limited production cycle and insufficient capacity increase at a single workstation, and further unleash the capacity advantages of automated production.

[0075] In this embodiment, the palletizing plates of the first lifting and palletizing mechanism and the second lifting and palletizing mechanism are both designed to have two independent placement areas arranged one after the other along the conveyor belt mechanism. The two placement areas are independent of each other and have no structural interference. Each placement area can independently stack a stack of book stickers to be pasted.

[0076] During the equipment initialization phase, the controller lowers the pallet of the first lifting and palletizing mechanism to the initial loading position. The operator places a stack of first book stickers to be glued in each of the two independent placement areas of the first lifting and palletizing mechanism's palletizing plate. Simultaneously, a stack of second book stickers to be glued is placed in each of the two independent placement areas of the second lifting and palletizing mechanism's palletizing plate. Subsequently, the controller raises the palletizing plates of both lifting and palletizing mechanisms so that the upper surface of the top layer of book stickers in both placement areas reaches the preset constant material picking height, completing the dual-station loading preparation.

[0077] During equipment operation, the controller controls the first transfer mechanism to simultaneously transfer the topmost first book stickers in the two placement areas of the first lifting and palletizing mechanism, while smoothly pushing the two first book stickers to the corresponding dual-station positioning positions of the gluing station; simultaneously controlling the gluing mechanism to apply glue to the two first book stickers according to the preset dual-station gluing path; after the gluing is completed, controlling the belt conveyor mechanism to simultaneously and accurately transport the two glued first book stickers to the corresponding dual-station positioning positions of the pressing station.

[0078] Subsequently, the controller controls the second transfer mechanism to simultaneously transfer the topmost second book stickers in the two placement areas of the second lifting and stacking mechanism, while pushing the two second book stickers to the pressing station, where they are precisely stacked on top of the two first book stickers in their corresponding positions. The drive detection device simultaneously completes the content matching verification between the two second book stickers and the corresponding first book stickers. After the verification is passed, the controller controls the pressing mechanism to simultaneously perform the pressing action on the two sets of stacked book stickers, and resets after the pressure is maintained. Finally, the controller controls the belt conveyor mechanism to simultaneously transport the two sets of finished book stickers to the unloading guide plate to complete the automatic unloading. The bonding and assembly of the two sets of book stickers is completed in a single operation cycle, which greatly improves the overall production efficiency of the machine.

[0079] In some embodiments, the step of gradually raising the bookplates after the top layer of bookplates is removed to maintain a constant picking height includes: acquiring the picking status of the top layer of bookplates in the corresponding placement areas of the first lifting and stacking mechanism and the second lifting and stacking mechanism; when it is detected that the top layer of bookplates in the corresponding placement area has been removed, controlling the drive motor of the corresponding lifting and stacking mechanism to drive the screw to rotate, causing the stacking plate to rise vertically along the guide shaft by a distance equal to the thickness of a bookplate, so that the top layer of the remaining bookplates in the corresponding placement area always maintains a preset constant picking height.

[0080] The core of this embodiment is to define the closed-loop control logic of constant material picking height. Through real-time monitoring of material picking status and precise lifting control at the book sticker thickness level, automatic constant compensation of material picking height is achieved, further ensuring the stability of material feeding, completely solving the problems of material picking failure and book sticker grabbing offset, adapting to different material feeding modes of single / double placement areas, and ensuring the stability of continuous production.

[0081] In this embodiment, the controller has built-in parameters for book sticker thickness and preset values ​​for constant material picking height. At the same time, through electrical connection with the drive elements of the first and second transfer mechanisms and the corresponding position sensor signals, it can obtain the material picking status of the top layer of book stickers in the corresponding placement areas of the two lifting and palletizing mechanisms in real time.

[0082] During equipment operation, the controller monitors the action signals of the first transfer mechanism in real time. When it receives the signal that the first transfer mechanism has completed pushing and the telescopic rod has been reset, it determines that the first book sticker on the top layer of the corresponding placement area has been successfully removed. It immediately generates a lifting control command and sends it to the first drive motor. The first drive motor rotates precisely according to the preset rotation parameters, drives the first screw to rotate, and drives the palletizing plate to be lifted vertically and smoothly upward along the guide shafts on both sides by a preset book sticker thickness, so that the top surface of the remaining book stickers returns to the preset constant picking height, waiting for the next picking.

[0083] Similarly, the controller monitors the action signals of the second transfer mechanism in real time. When it detects that the second book sticker on the top layer of the corresponding placement area of ​​the second lifting and palletizing mechanism has been successfully removed, it immediately controls the corresponding drive motor to lift the palletizing plate by the thickness of one book sticker, maintaining a constant material picking height.

[0084] For the dual-placement-area structure, this embodiment can realize independent lifting control of the two placement areas: when the book sticker in one of the placement areas is removed, the controller only controls the corresponding pallet to perform the lifting action. The lifting control of the two placement areas is independent of each other and does not interfere with each other, ensuring that the material picking height of the two placement areas can always be kept constant during dual-station operation.

[0085] In some embodiments, controlling the first transfer mechanism to transfer the first book label to the dispensing station of the belt conveyor mechanism includes: controlling the cylinder of the first transfer mechanism to drive the transfer plate to move linearly along the guide seat, pushing the first book label on the uppermost layer of the corresponding placement area of ​​the first lifting and stacking mechanism to move towards the dispensing station; during the pushing process, the transfer posture of the first book label is corrected by the guide slope of the guide ribs correspondingly provided on the frame, and the first book label is smoothly pushed to the preset position of the dispensing station of the belt conveyor mechanism.

[0086] The core of this embodiment is to clarify the precise control logic for the transfer of the first book label. By using a cylinder-driven linear push and a self-correcting structure for the guide slope, the problems of deviation, positional offset, and angle deflection during the transfer of the book label are solved, ensuring that the book label enters the dispensing station with a precise posture and position, providing a precision foundation for subsequent glue application and mating pressing.

[0087] In this embodiment, the first transfer mechanism adopts a cylinder-driven push-type transfer structure, which includes a guide seat fixed on the frame, a cylinder installed at one end of the guide seat, and a transfer plate connected to the cylinder telescopic rod. The transfer plate slides in cooperation with the linear guide rail on the guide seat. Two guide ribs are correspondingly provided on the two outlet positions of the first lifting and stacking mechanism on the frame, and each guide rib is provided with a guide slope on the side facing the stacking plate.

[0088] Before the transfer action is executed, the controller controls the first transfer mechanism to the initial state: the cylinder extension rod is in the retracted state, the transfer plate is located on the side of the first book sticker facing away from the dispensing station, aligned with the side of the topmost first book sticker, waiting for the transfer command.

[0089] After the controller confirms that the material picking height is constant and the equipment is normal, it sends an extension command to the cylinder solenoid valve, controls the cylinder telescopic rod to extend at a constant speed, drives the transfer plate to make a high-precision linear forward movement along the linear guide rail of the guide seat, and the front end of the transfer plate smoothly contacts the side of the first book sticker, continuously pushing the first book sticker to move horizontally towards the dispensing station.

[0090] During the push process, the two sides of the book sticker enter the guide area of ​​the two guide ribs and naturally contact the guide slopes on both sides. If the first book sticker has a slight initial position offset or angle deviation, it will automatically complete the posture correction under the guidance of the guide slopes, gradually return to the correct centered transfer path, and eliminate position and angle deviations.

[0091] When the cylinder extension rod extends to the preset stroke, the transfer plate will smoothly push the first book label, which has completed posture correction, to the preset positioning position of the dispensing station. The controller controls the cylinder extension rod to retract, driving the transfer plate to reset, thus completing the precise transfer operation of the first book label in a single operation.

[0092] In some embodiments, the driving detection device performs content recognition verification on the first book sticker, including: controlling the industrial camera of the detection device to capture a surface image of the first book sticker, extracting key feature information from the image, the key feature information including at least page numbers and barcodes; comparing the extracted key feature information with a pre-stored standard book sticker feature template, determining whether the content and model of the first book sticker meet the preset assembly requirements, and generating a corresponding content recognition verification result.

[0093] The core of this embodiment is to clarify the specific implementation logic of the first book sticker pre-content recognition. Through image acquisition, feature extraction, and template comparison by industrial machine vision, the content of the book sticker is automatically and with high precision verified. This solves the problems of visual fatigue during manual verification, mismatch and missed detection, and the inability to intercept errors in advance during post-processing. It prevents erroneous book stickers from entering subsequent processes from the assembly source.

[0094] In this embodiment, the detection device uses one or more sets of high-resolution industrial cameras, which are installed near the first transfer mechanism and electrically connected to the controller. The controller has a pre-stored standard book label feature template corresponding to this production task, which includes key information such as the page number, barcode, and layout features of the standard book label, as well as the corresponding qualified comparison threshold.

[0095] During the transfer of the first book sticker or after it reaches the dispensing station and is positioned, the controller immediately sends a shooting command to the industrial camera to control the camera to take a high-definition picture of the entire surface of the first book sticker, obtain a clear surface image, and transmit the image data to the controller in real time.

[0096] After receiving the image data, the controller starts the built-in image recognition algorithm to perform preprocessing such as denoising, grayscale conversion, and distortion correction on the image. Then, it extracts the key feature information of the first book label from the preprocessed image, including at least the page number and barcode / QR code information. It can also extract auxiliary verification information such as page layout and content block features as needed.

[0097] The controller will extract key feature information and compare it with the pre-stored standard book sticker feature template feature by feature to calculate the feature matching degree. If the matching degree reaches the preset qualified threshold, the first book sticker is determined to meet the assembly requirements and a "content recognition verification passed" result is generated. If the matching degree does not reach the threshold, or there are abnormalities such as page number errors, barcode mismatches, or missing content, it is determined to not meet the requirements and a "content recognition verification failed" result is generated, and abnormal feature information is recorded simultaneously.

[0098] The controller uses the verification results as the basis for controlling subsequent processes. If the verification passes, the gluing process is allowed to proceed; if the verification fails, an alarm is triggered and the machine is stopped immediately, thus achieving proactive interception of errors in the book's pasted content.

[0099] In some embodiments, the step of controlling the dispensing mechanism to apply glue to a preset position of the first book sticker after the content recognition verification is passed, and then controlling the conveyor belt mechanism to transport the glued first book sticker to the pressing station, includes: after receiving the result that the content recognition verification of the first book sticker is passed, controlling the drive motor of the dispensing mechanism to drive the screw to rotate, driving the glue gun on the mounting plate to move along the conveying direction of the conveyor belt mechanism, and applying glue to the specified position of the first book sticker according to the preset glue application path; after the glue application is completed, controlling the servo motor of the conveyor belt mechanism to drive the conveyor belt to run, and accurately transporting the glued first book sticker to the preset position of the pressing station.

[0100] The core of this embodiment is to clarify the linkage control logic between the glue application process and the pre-verification results, as well as the implementation method of accurate glue application and accurate workstation flow, to achieve closed-loop collaborative control between processes, solve the problem of material waste caused by no linkage between processes and abnormal materials still performing subsequent actions in the existing technology, and at the same time ensure the accuracy of glue application and workstation flow.

[0101] In this embodiment, the dispensing mechanism is mounted above the dispensing station and includes a second bracket, a mounting plate that can slide along the belt conveyor direction, a vertically mounted dispensing gun, a glue tank, and a screw drive pair consisting of a second drive motor and a second screw. The belt conveyor mechanism is driven by a servo motor, which can achieve high-precision start-stop and positioning. The controller has preset glue application paths, glue application parameters, and station conveying parameters corresponding to the book sticker model.

[0102] The controller receives the content recognition and verification results of the first book sticker in real time. Only when it receives a "verification passed" result will it start the subsequent glue application process. If it receives a "verification failed" result, it will immediately stop the glue application action, thus realizing closed-loop linkage control of the process.

[0103] After the verification is passed, the controller sends a control command to the second drive motor, which rotates precisely according to the preset speed and number of rotations, driving the second screw to rotate synchronously and causing the mounting plate to move at a constant speed along a path parallel to the belt conveyor direction; the glue gun moves synchronously, and at the same time the controller controls the delivery pump of the glue tank to start, providing a stable glue supply to the glue gun. The glue gun completes uniform and precise glue application to the designated position of the first book sticker according to the preset glue application path, glue amount, and glue application speed.

[0104] After the adhesive is applied, the controller stops the delivery pump from supplying adhesive and the dispensing gun from dispensing adhesive. At the same time, it controls the second drive motor to rotate in reverse, driving the mounting plate and the dispensing gun to return to their initial positions.

[0105] Synchronously, the controller sends precise operating commands to the servo motor of the belt conveyor mechanism, controlling the servo motor to drive the conveyor belt to smoothly and accurately transport the first book sticker after dispensing to the preset positioning position of the pressing station; after reaching the position, the controller controls the servo motor to stop running, the conveyor belt to lock, and the first book sticker to be fixed at the pressing station, completing the precise transfer between stations.

[0106] In some embodiments, controlling the second transfer mechanism to transfer the second book sticker to the pressing station and stack it on top of the first book sticker includes: controlling the cylinder of the second transfer mechanism to drive the transfer plate to move linearly along the corresponding guide seat, pushing the second book sticker at the top of the corresponding placement area of ​​the second lifting and stacking mechanism to move towards the pressing station; correcting the transfer posture of the second book sticker by the guide slope of the corresponding guide rib during the pushing process, and smoothly pushing the second book sticker to the pressing station, stacking it directly above the first book sticker that has been glued; ensuring the precise stacking and alignment of the second book sticker and the first book sticker, solving the problems of book sticker position offset, folding corners, and contamination caused by manual transfer, and providing accuracy assurance for the quality of subsequent pressing and bonding.

[0107] In this embodiment, the second transfer mechanism and the first transfer mechanism adopt the same cylinder-driven push-type transfer structure, including a corresponding guide seat, cylinder, and transfer plate; on both sides of the second lifting and stacking mechanism, there are corresponding guide ribs with guide slopes; the second transfer mechanism spans between the second lifting and stacking mechanism and the pressing station, and the controller has preset transfer stroke and stacking positioning parameters for the second book sticker.

[0108] Before the transfer action is executed, the controller confirms that the first book sticker after dispensing has accurately reached the pressing station and completed the positioning and locking. At the same time, it confirms that the picking height of the second lifting and stacking mechanism is constant, and controls the second transfer mechanism to be in the initial state: the cylinder telescopic rod is retracted, the transfer plate is located on the side of the second book sticker facing away from the pressing station, aligned with the side of the topmost second book sticker, waiting for the transfer command.

[0109] The controller sends an extension command to the cylinder solenoid valve of the second transfer mechanism, controlling the cylinder telescopic rod to extend at a constant speed, driving the transfer plate to make a high-precision linear forward movement along the linear guide rail of the corresponding guide seat. The front end of the transfer plate smoothly contacts the side of the second book sticker, continuously pushing the second book sticker to move horizontally towards the pressing station.

[0110] During the pushing process, the two sides of the book sticker enter the guide zone of the corresponding guide rib and contact the guide slope on both sides. If the second book sticker has an initial position offset or angle deviation, it will automatically complete the posture correction under the guidance of the guide slope to eliminate the deviation and ensure that the transfer path is centered and the posture is correct.

[0111] When the cylinder extension rod extends to the preset stroke, the transfer plate smoothly pushes the second book sticker, which has completed posture correction, to the preset position of the pressing station, and accurately stacks it directly above the first book sticker that has been glued, so as to achieve edge alignment and precise position matching of the two book stickers; the controller controls the cylinder extension rod to retract, driving the transfer plate to reset, and completing the precise transfer and stacking operation of the second book sticker in one operation.

[0112] In some embodiments, the driving detection device performs content matching verification on the second book sticker, including: controlling the industrial camera of the detection device to capture a surface image of the second book sticker, extracting key feature information from the image, the key feature information including at least page numbers and barcodes; performing a dual comparison between the extracted key feature information of the second book sticker and the feature information of the corresponding stacked first book sticker and a pre-stored pairing assembly standard, determining whether the second book sticker and the first book sticker are a matching assembly pair, and generating a corresponding content matching verification result.

[0113] The core of this embodiment is to clarify the pairing and verification logic between the second and first bookmarks. Through a dual comparison mechanism of "standard template + corresponding first bookmark features", high-precision verification of assembly and pairing is achieved, solving the problems of high mismatch rate in manual sampling and inability to intercept errors in post-processing detection in the existing technology. This completely eliminates quality accidents such as bookmark mismatch and page number reversal, and ensures the pass rate of finished products.

[0114] In this embodiment, the industrial camera of the detection device covers both the second transfer mechanism and the pressing station area, and is electrically connected to the controller; the controller has pre-stored the matching assembly standard corresponding to this production task, which clarifies the matching relationship between the first book sticker and the second book sticker, and also stores the key feature information extracted from the corresponding first book sticker.

[0115] During the transfer of the second book sticker or after it is stacked and positioned, the controller immediately sends a shooting command to the industrial camera to control the camera to take a high-definition picture of the entire surface of the second book sticker, obtain a clear surface image, and transmit the image data to the controller in real time.

[0116] After receiving the image data, the controller preprocesses the image using a built-in image recognition algorithm and then extracts the key feature information of the second book sticker, including at least page number and barcode / QR code information. It can also extract auxiliary verification information such as page layout identifiers and content block features as needed.

[0117] The controller performs a dual comparison and verification: the first comparison compares the key feature information of the second book sticker with the pre-stored pairing and assembly standards to confirm that the model and content of the second book sticker itself meet the assembly requirements of this production; the second comparison compares the key feature information of the second book sticker with the key feature information extracted from the first book sticker currently stacked to confirm that the two are a preset matching assembly pair and there are no problems such as mismatch, page number reversal, or content mismatch.

[0118] The controller will only generate a "content matching verification passed" result when both comparisons meet the preset requirements and the matching degree reaches the qualified threshold. If either comparison fails to meet the requirements, a "content matching verification failed" result will be generated immediately, and the abnormal information will be recorded synchronously.

[0119] The controller uses the verification results as the basis for controlling the subsequent pressing process. If the verification passes, the pressing process is allowed to proceed. If the verification fails, an audible and visual alarm is triggered immediately and the machine is stopped, prohibiting the pressing action from being performed. This achieves pre-interception of book label mismatch and avoids finished product scrap and material waste.

[0120] In some embodiments, the step of controlling the pressing mechanism to press the stacked book stickers after the content matching verification is passed, thereby completing the book sticker assembly, includes: after receiving the result that the content matching verification of the second book sticker is passed, controlling the drive motor of the pressing mechanism to drive the screw to rotate, causing the pressing component to descend vertically to a preset pressing position, applying a preset pressure to the stacked first and second book stickers and maintaining a preset pressure holding time; after the pressure holding is completed, controlling the pressing component to rise and reset, completing the book sticker assembly, and then controlling the belt conveyor mechanism to transport the assembled book stickers to the unloading guide plate to complete the automatic unloading.

[0121] The core of this embodiment is to clarify the linkage control logic between the pressing process and the pre-pairing verification results, as well as the implementation method of precise pressing and automatic unloading of finished products, to achieve collaborative closed-loop control of the entire process, ensure the quality of pressing and bonding, and at the same time complete the automated collection of finished products, so as to realize the fully automated and continuous production of the entire process of book sticker bonding and assembly.

[0122] In this embodiment, the pressing mechanism is installed above the pressing station and includes a third bracket, a pressing component that can slide up and down, a screw drive pair consisting of a third drive motor and a third screw, and a flat pressing plate at the bottom of the pressing component; the end of the belt conveyor mechanism is provided with a feeding guide plate with an inclined slope; the controller is preset with pressing stroke, pressing pressure, holding time, and feeding and conveying parameters.

[0123] The controller receives the content matching and verification results of the second book sticker in real time. Only when it receives the "verification passed" result will it start the subsequent pressing process. If it receives the "verification failed" result, it will immediately prohibit the pressing action, realizing closed-loop linkage control of the entire process.

[0124] After the verification is passed, the controller sends a forward rotation control command to the third drive motor, which rotates precisely according to the preset speed and number of rotations, driving the third screw to rotate synchronously in the forward direction. This causes the pressing component to descend vertically and smoothly along the third support until it reaches the preset pressing position. The flat pressure plate at the bottom of the pressing component makes full contact with the upper surface of the stacked second book stickers, applying a preset stable pressure to the two layers of book stickers. At the same time, the controller starts timing and maintains the preset pressure holding time to allow the adhesive to fully impregnate and cure, achieving a tight bond between the book stickers.

[0125] After the pressure holding time reaches the preset value, the controller sends a reverse rotation control command to the third drive motor, controlling the motor to rotate in the opposite direction, driving the pressing component to rise vertically and reset to the initial position, waiting for the next pressing command, thus completing the bonding and assembly of the book sticker.

[0126] The controller then sends operation control commands to the servo motor of the belt conveyor mechanism, controlling the servo motor to drive the conveyor belt to transport the finished book stickers from the pressing station to the unloading guide plate at the end. After the finished book stickers reach the unloading guide plate, they slide smoothly down the inclined slope under the action of gravity and finally fall neatly into the collection basket or flow into the downstream process, completing the automatic unloading and collection of finished products and realizing the fully automated operation of the entire process of single book sticker bonding and assembly.

[0127] In some embodiments, the existing technology can only achieve a fixed process of bonding single-specification, double-layer book stickers. Faced with the publishing industry's demand for small-batch, multi-batch, multi-size / thickness mixed-line production of book stickers, as well as the multi-layer assembly needs of covers, title pages, multiple sets of inner pages and inserts, it is necessary to frequently stop the machine to change tooling, modify control programs, and manually stack and load materials. The changeover time is long and the production efficiency is extremely low, making it impossible to achieve flexible production. This is the core pain point of small-batch order production in the current industry.

[0128] This embodiment breaks through the existing production limitations of double bookmarks and single specifications. Through multiple independently schedulable lifting and palletizing mechanisms, adaptive recognition of bookmark specifications, and cyclic linkage control of multi-layer processes, it enables continuous production of mixed bookmarks of different specifications and stacking quantities without downtime for model changes. At the same time, through full-process specification matching verification and stacking sequence closed-loop control, it solves the problems of mismatch, size mismatch, and stacking sequence errors in mixed-line production, taking into account the needs of large-scale standardized production and small-batch flexible production, and greatly improving equipment adaptability and production efficiency.

[0129] By extending the original frame along the conveyor belt mechanism, N sets (N≥3) of independently controllable lifting and palletizing mechanisms and matching transfer mechanisms are installed. Each lifting and palletizing mechanism is equipped with an independent detection device, and all mechanisms are electrically connected to the controller. Each lifting and palletizing mechanism's palletizing plate is equipped with a quickly adjustable side limit baffle, and a laser rangefinder sensor is installed on the baffle to identify the size and single-sheet thickness parameters of the book stickers in real time. The conveyor belt mechanism adopts segmented servo drive, with the dispensing station and multiple pressing stations arranged sequentially along the conveyor direction. Each pressing station is equipped with an independent dispensing mechanism and pressing mechanism, which can independently execute control commands.

[0130] The controller pre-stores the BOM (Bill of Materials) list for book sticker assembly corresponding to the production order, including the stacking order, specifications of each layer of book stickers, and matching relationships. During equipment initialization, operators can place book stickers of different specifications and stacks on different groups of lifting and palletizing mechanisms without having to arrange them in a fixed order. The controller drives the laser rangefinder of each group of lifting and palletizing mechanisms to scan the size, single sheet thickness, and stacking height of the book stickers in the corresponding placement area, automatically identifying the book sticker specifications and automatically matching and binding them with the BOM list to generate the corresponding workstation's scheduling and control program. At the same time, the controller controls each group of lifting and palletizing mechanisms to automatically raise the corresponding thickness distance after the corresponding book sticker is removed, based on the identified single sheet thickness, maintaining the independent and constant material picking height of each group. This eliminates the need for manual input of thickness parameters and achieves adaptive feeding of multiple specifications of book stickers without adjustment.

[0131] The controller, following the stacking order of the BOM (Bill of Materials), dispatches the first transfer mechanism corresponding to the first layer of book stickers (such as the cover) to the first dispensing station. During the transfer, the corresponding detection device captures images of the book stickers, performing content recognition and verification on one hand, and secondary recognition of the book sticker's specifications on the other, comparing them with the BOM and pre-bound specifications to confirm that the book sticker's specifications and content fully match the first layer stacking requirements. After verification, the controller automatically adjusts the dispensing mechanism's glue path, glue length, and glue gun spacing based on the identified book sticker size, without requiring manual program modification, controlling the dispensing mechanism to complete adaptive and precise glue application. After glue application, the segmented belt conveyor system accurately delivers the first layer of book stickers to the first pressing station, completing the first layer process flow.

[0132] The controller, following the stacking order in the BOM (Bill of Materials), sequentially dispatches the transfer mechanism corresponding to the next layer of bookplates, transferring the corresponding bookplates to the current pressing station and stacking them on top of the previous layer of bookplates that have already been glued. During the transfer, the detection device completes the bookplate content recognition and specification recognition, and performs a double matching verification with the specifications of the previous layer of bookplates and the BOM list to confirm that the stacking order, specification matching, and content matching are correct. After the verification is passed, the controller automatically adjusts the pressing stroke, pressing pressure, and holding time of the pressing mechanism according to the current total thickness of the stack, controlling the pressing mechanism to complete adaptive pressing. After the pressing of this layer is completed, the controller determines the stacking progress according to the BOM list: if stacking needs to continue, it controls the glue dispensing mechanism to complete adaptive glue application to the current topmost bookplate, and then controls the conveyor belt mechanism to transport the bookplate to the next pressing station, repeating the above transfer, verification, and pressing process until all stacking assembly required by the BOM list is completed; if all stacking is completed, it controls the conveyor belt mechanism to transport the finished product to the unloading guide plate for automatic unloading.

[0133] For different batches and specifications of book stickers within the same order, or for multiple small-batch orders to be executed simultaneously, the controller can automatically identify the specifications of book stickers on different lifting and palletizing mechanisms, automatically split the order tasks, and schedule the corresponding mechanisms to complete the continuous assembly of book stickers of different specifications. After the last batch of finished products of the previous specification is assembled, the machine can automatically switch to the assembly program of the next specification of book stickers without stopping, thus realizing uninterrupted mixed-line production.

[0134] In some embodiments, in the prior art, once abnormalities such as book stickers or failure to pick up materials are detected, the machine can only be stopped and awaited manual handling, resulting in production interruption and efficiency loss. At the same time, even if the abnormal materials have been determined to be unqualified in the previous process, the subsequent gluing and pressing actions will still be performed, resulting in serious waste of glue and paper. In addition, there is no adaptive correction mechanism for minor abnormalities such as failure to pick up materials or book sticker misalignment, which can only be dealt with by stopping the machine. This makes it impossible to achieve true continuous production and is the core bottleneck of the operational stability of existing equipment.

[0135] This embodiment constructs a full-process anomaly control system encompassing anomaly identification, tiered handling, adaptive correction, and closed-loop feedback. It breaks through the existing "anomaly equals shutdown" control logic, implementing tiered adaptive handling for different types of anomalies. Minor anomalies can be automatically corrected without shutdown, while severe anomalies can be diverted and intercepted. Simultaneously, it achieves seamless, pressure-free diversion of abnormal materials throughout the entire process, completely eliminating material waste. Through closed-loop feedback of anomaly data, it automatically optimizes the control parameters of preceding processes, achieving self-improvement in production stability, ensuring continuous 24 / 7 operation of equipment, and significantly improving production efficiency and finished product yield.

[0136] Based on the original equipment, position sensors, visual positioning sensors, and double-sheet detection sensors are added to each material picking position of the lifting and palletizing mechanism, the transfer path of the transfer mechanism, the dispensing station, the pressing station, and the end of the belt conveyor. All sensors and detection devices are electrically connected to the controller. The controller has a built-in abnormality classification and handling model, with preset abnormality type classification rules, corresponding handling strategies, and parameter self-optimization algorithms. Defective product diversion mechanisms are added next to the belt conveyor mechanism, located upstream of the dispensing station and downstream of the pressing station, respectively. These mechanisms can divert defective book covers from the main conveyor line to the defective product collection area without affecting the continuous operation of the main process.

[0137] The controller monitors the material handling status of the lifting and palletizing mechanism in real time. It uses a double-sheet detection sensor to identify whether double-sheet handling or material handling failure occurs, and uses a laser rangefinder to monitor the lifting height of the palletizing plate and the flatness of the top layer of book stickers in real time.

[0138] When a single material retrieval failure is detected (the arrival sensor does not detect the arrival of the book sticker after the transfer mechanism pushes it), the controller immediately triggers the replenishment process: without stopping the machine, the corresponding lifting and palletizing mechanism is slightly raised by 0.2 times the book sticker thickness, and then the transfer mechanism is controlled to perform a second replenishment push action, while the material retrieval failure event is recorded; if two consecutive replenishment failures occur, it is judged as a serious feeding abnormality. The controller only suspends the feeding action of the corresponding station, while the other stations operate normally, and an alarm is triggered to prompt manual handling, without affecting the continuous production of the whole machine.

[0139] When double-sheet material is detected, the controller immediately stops the transfer mechanism and controls the conveyor belt mechanism to directly transport the double sheets of book stickers to the defective product diversion mechanism, diverting them to the defective product area and preventing them from entering the subsequent gluing process. At the same time, the controller controls the corresponding lifting and palletizing mechanism to perform a material replenishment action, without stopping the machine throughout the entire process.

[0140] The controller accumulates and records abnormal data such as material picking failures and double-sheet picking. Through a self-optimization algorithm, it automatically adjusts the lifting compensation of the palletizing plate, the pushing speed and stroke of the transfer mechanism, optimizes the material picking parameters, reduces the occurrence of subsequent abnormalities, and achieves closed-loop self-improvement of material picking stability.

[0141] During the first book label transfer process, the controller monitors the book label's transfer posture in real time using a visual positioning sensor. When it detects that the book label's offset exceeds the preset threshold but has not completely deviated, it immediately controls the transfer mechanism to slow down the pushing speed and works with the guide slope of the guide rib to complete the posture correction, or controls the conveyor belt of the belt conveyor mechanism to rotate slightly in the opposite direction to complete the online automatic correction of the book label's posture without stopping the machine. If the offset exceeds the maximum correctable threshold, it is determined to be an abnormal posture. The controller prohibits the dispensing mechanism from starting and controls the belt conveyor mechanism to directly divert the abnormal book label to the defective product area, while triggering the replenishment process, without stopping the machine at all.

[0142] When the detection device detects that the content of the first book sticker fails the verification, the controller immediately stops the glue dispensing mechanism from performing the glue application action and controls the belt conveyor mechanism to directly transport the abnormal book sticker to the defective product diversion mechanism, diverting it to the defective product area, completely avoiding glue waste; at the same time, it synchronously controls the first lifting and palletizing mechanism and the transfer mechanism to perform the replenishment action, and the remaining normal book stickers on the main conveyor line continue to perform subsequent processes without stopping production.

[0143] In response to abnormalities in the glue application process, the controller monitors the glue dispensing volume in real time through the pressure sensor of the glue gun. When abnormal glue dispensing or glue leakage is detected, the controller immediately stops the conveyor belt mechanism from conveying downstream and diverts the abnormal booklet to the defective product area, preventing it from entering the pressing process. At the same time, an alarm is triggered to prompt manual inspection of the glue dispensing mechanism to avoid the generation of a batch of defective products.

[0144] During the second book sticker transfer and stacking process, the controller monitors the stacking alignment accuracy in real time through a visual positioning sensor. When the stacking offset is detected to be within the correctable range, the controller controls the conveyor belt of the belt conveyor mechanism to slightly reverse, and with the assistance of the transfer mechanism, completes the online automatic correction of the stacking position. If the offset exceeds the correctable range, or the content matching verification fails, the controller immediately prevents the pressing mechanism from starting and controls the belt conveyor mechanism to divert the abnormal book stickers to the defective product area to avoid the complete scrapping of materials caused by ineffective pressing. At the same time, the replenishment process is triggered, and the machine does not stop throughout the entire process.

[0145] After the pressing is completed, the controller performs a secondary visual inspection of the finished product through the detection device to identify defects such as glue separation, mismatched layers, and surface contamination. If a defective product is detected, the controller controls the diversion mechanism to divert it to the defective product area, while only qualified finished products are transported to the qualified receiving area through the unloading guide plate. At the same time, the defective product data is fed back to the previous glue application and pressing processes, and parameters such as glue application amount, pressing pressure, and holding time are automatically adjusted to achieve closed-loop control of finished product quality.

[0146] Throughout the entire anomaly handling process, the controller only performs diversion and replenishment operations on abnormal materials, while the production process of normal materials remains uninterrupted, completely solving the industry pain point of "shutting down immediately upon an anomaly." At the same time, all abnormal materials are exempt from unnecessary gluing and pressing operations, minimizing material waste and achieving closed-loop production with zero ineffective material consumption.

[0147] In some embodiments, existing book pasting equipment operates as stand-alone machines, completely disconnected from upstream folding and collating machines, and downstream sewing and binding machines. This requires manual material handling, which not only increases labor costs but also causes book pasting to become soiled and folded due to repeated handling. At the same time, the capacity of a single machine cannot match the pace of upstream and downstream production lines. Mass production requires multiple stand-alone machines to operate in parallel, which is difficult to schedule manually, makes it impossible to control order delivery progress, and makes it impossible to achieve automated continuous production throughout the entire printing and binding process.

[0148] This embodiment breaks through the limitations of single-machine operation and constructs a full-link intelligent production system of "upstream equipment online material feeding - multiple laminating machines networked and coordinated scheduling - downstream equipment seamless connection". Through production line-level collaborative control, it realizes the entire process of book pasting from folding to lamination and assembly, and then into the next process without manual turnover. At the same time, through multi-machine collaborative order splitting and cycle matching, it realizes dynamic allocation of production capacity, solves the problems of single machine capacity bottleneck, high manual turnover cost, and production line cycle mismatch, and realizes fully automated, intelligent and continuous production of the entire printing and binding process.

[0149] By establishing a production line management system centered on a controller, multiple folding and collating machines are connected upstream, and sewing and perfect binding machines are connected downstream. A network connects M (M≥2) book-attachment assembly machines in the middle. All equipment communicates with the controller via an industrial Ethernet network. Each local controller on each assembly machine can receive scheduling commands from the main controller and simultaneously provide real-time feedback to the central controller on equipment operating status, production progress, material reserves, and any abnormal information. The first and second lifting and palletizing mechanisms of each assembly machine are integrated into the online feeding mechanism and connect to the discharge port of the upstream folding machine, enabling direct online palletizing of folded book-attachments without manual handling.

[0150] The controller distributes production tasks to each bonding and assembly machine based on the total production order and delivery date. At the same time, it sends production instructions to the corresponding upstream folding machine, controlling the folding machine to complete the folding and cutting of the book stickers according to the order requirements. The folded book stickers are then directly fed into the online feeding mechanism of the corresponding bonding and assembly machine via the conveyor line.

[0151] The online feeding mechanism automatically stacks and places the folded book stickers into the corresponding palletizing area of ​​the lifting and palletizing mechanism, eliminating the need for manual palletizing and loading. The controller monitors the stacking height of the book stickers in the placement area in real time through a laser rangefinder. When the stacking height reaches the preset upper limit, the controller switches the online feeding mechanism to another placement area for palletizing. At the same time, it controls the already full placement area to start the loading operation, realizing continuous production of palletizing and loading at the same time, completely eliminating the manual loading and turnover link.

[0152] The controller monitors the remaining amount of book stickers in each placement area in real time. When the remaining amount is lower than the preset threshold, a replenishment request is sent to the controller in advance. The controller schedules the upstream folding machine to complete the production of the corresponding book stickers first. The replenishment is completed without stopping the machine by the online feeding mechanism. At the same time, the corresponding lifting and palletizing mechanism is controlled to maintain a constant picking height to ensure the continuity of feeding.

[0153] The controller collects the production cycle time of each laminating and assembly machine and the operating speed of upstream and downstream equipment in real time, and dynamically adjusts the process operating parameters of each laminating and assembly machine to achieve precise matching of the production line cycle time: when the upstream folding machine output speed increases, the controller schedules the local controller of the corresponding laminating and assembly machine to increase the operating speed of the transfer, dispensing, and pressing processes, thereby speeding up the production cycle time; when the downstream downstream equipment processing speed slows down, the controller schedules the laminating and assembly machine to reduce the production cycle time, and at the same time controls the finished product temporary storage mechanism to complete the temporary storage of qualified finished products to avoid production line blockage, without the need for manual intervention throughout the entire process.

[0154] Each bonding and assembly machine's local controller executes the entire process of steps S102-S103 according to the controller's scheduling instructions: controlling the transfer mechanism to complete the transfer of book stickers, driving the detection device to complete the identification and matching verification of book sticker content, and controlling the dispensing and pressing processes to complete bonding and assembly after the verification is passed. The process execution parameters throughout the entire process are adaptively adjusted according to the controller's cycle scheduling instructions to ensure the production progress of multiple machines is synchronized.

[0155] When one of the bonding and assembly machines experiences an abnormal shutdown, the controller immediately and dynamically allocates the remaining production tasks of that machine to the other bonding and assembly machines that are operating normally. At the same time, it adjusts the material feeding and unloading rhythms of upstream and downstream equipment to ensure that the production line does not stop and the order delivery schedule is not affected. The abnormal information of the abnormal machine is simultaneously uploaded to the controller, triggering a remote alarm and prompting maintenance personnel to handle the situation.

[0156] Each qualified finished product completed by the bonding and assembly machine is directly fed into the main conveyor line of the production line through the feeding guide plate. The controller schedules the finished product conveyor line to accurately deliver the finished product to the feeding port of the corresponding thread-locking machine and binding machine according to the operating status of the downstream equipment, realizing the direct online flow of finished products without the need for manual collection and transfer, and completely eliminating the manual turnover links between processes.

[0157] The controller collects production data from the entire production line in real time, including order completion progress, finished product yield, equipment operating efficiency, and material consumption data. It automatically generates production reports and optimizes order splitting strategies and production line cycle time matching parameters based on historical production data, achieving intelligent management and control of the entire production chain.

The assembly control unit 203 is used to control the second transfer mechanism to transfer the second book sticker to the pressing station and stack it on top of the first book sticker, and drive the detection device to perform content matching verification on the second book sticker. After the content matching verification is passed, the control unit controls the pressing mechanism to press the stacked book stickers to complete the book sticker bonding assembly.

[0160] In some embodiments, the pallet plates corresponding to the first and second lifting palletizing mechanisms each include two independent placement areas arranged one after the other along the conveying direction of the belt conveyor mechanism; the control of the first and second lifting palletizing mechanisms to support the stacked first and second book labels respectively includes: controlling the two independent placement areas corresponding to the first lifting palletizing mechanism to support the stacked first book labels respectively, and controlling the two independent placement areas corresponding to the second lifting palletizing mechanism to support the stacked second book labels respectively.

[0161] In some embodiments, the step of gradually raising the bookplates after the top layer of bookplates is removed to maintain a constant picking height includes: acquiring the picking status of the top layer of bookplates in the corresponding placement areas of the first lifting and stacking mechanism and the second lifting and stacking mechanism; when it is detected that the top layer of bookplates in the corresponding placement area has been removed, controlling the drive motor of the corresponding lifting and stacking mechanism to drive the screw to rotate, causing the stacking plate to rise vertically along the guide shaft by a distance equal to the thickness of a bookplate, so that the top layer of the remaining bookplates in the corresponding placement area always maintains a preset constant picking height.

[0163] In some embodiments, the driving detection device performs content recognition verification on the first book sticker, including: controlling the industrial camera of the detection device to capture a surface image of the first book sticker, extracting key feature information from the image, the key feature information including at least page numbers and barcodes; comparing the extracted key feature information with a pre-stored standard book sticker feature template, determining whether the content and model of the first book sticker meet the preset assembly requirements, and generating a corresponding content recognition verification result.

[0165] In some embodiments, controlling the second transfer mechanism to transfer the second book sticker to the pressing station and stack it on top of the first book sticker includes: controlling the cylinder of the second transfer mechanism to drive the transfer plate to move linearly along the corresponding guide seat, pushing the second book sticker at the top of the corresponding placement area of ​​the second lifting and stacking mechanism to move towards the pressing station; correcting the transfer posture of the second book sticker by the guide slope of the corresponding guide rib during the pushing process, and smoothly pushing the second book sticker to the pressing station and stacking it directly above the first book sticker that has been glued.

[0166] In some embodiments, the driving detection device performs content matching verification on the second book sticker, including: controlling the industrial camera of the detection device to capture a surface image of the second book sticker, extracting key feature information from the image, the key feature information including at least page numbers and barcodes; performing a dual comparison between the extracted key feature information of the second book sticker and the feature information of the corresponding stacked first book sticker and a pre-stored pairing assembly standard, determining whether the second book sticker and the first book sticker are a matching assembly pair, and generating a corresponding content matching verification result.

[0168] It should be noted that those skilled in the art will understand that, for the sake of convenience and brevity, the specific working process of the adaptive book sticker bonding assembly system and its modules described above can be referred to the corresponding content in the various embodiments of the adaptive book sticker bonding assembly method, and will not be repeated here.

[0169] The aforementioned adaptive book-sticking assembly method can be implemented as a computer program, which can, for example, Figure 9 It runs on the device shown.

The specific controller may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0175] It should be understood that the processor can be a Central Processing Unit (CPU), but it can also be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. Among these, a general-purpose processor can be a microprocessor or any conventional processor.

[0176] In one embodiment, the processor is configured to run a computer program stored in memory to perform the following steps: The first and second lifting and stacking mechanisms are controlled to support the stacked first and second book stickers respectively. After the top book sticker is removed, the book stickers are lifted level by level to maintain a constant material picking height. The first transfer mechanism is controlled to transfer the first book sticker to the glue dispensing station of the belt conveyor mechanism. The detection device is driven to perform content recognition and verification on the first book sticker. After the content recognition and verification is passed, the glue dispensing mechanism is controlled to apply glue to the preset position of the first book sticker. Then, the belt conveyor mechanism is controlled to transport the glued first book sticker to the pressing station. The second transfer mechanism is controlled to transfer the second book sticker to the pressing station and stack it on top of the first book sticker. The detection device is driven to perform content matching verification on the second book sticker. After the content matching verification is passed, the pressing mechanism is controlled to press the stacked book stickers to complete the book sticker bonding assembly.

[0177] In some embodiments, the pallet plates corresponding to the first and second lifting palletizing mechanisms each include two independent placement areas arranged one after the other along the conveying direction of the belt conveyor mechanism; the control of the first and second lifting palletizing mechanisms to support the stacked first and second book labels respectively includes: controlling the two independent placement areas corresponding to the first lifting palletizing mechanism to support the stacked first book labels respectively, and controlling the two independent placement areas corresponding to the second lifting palletizing mechanism to support the stacked second book labels respectively.

[0178] In some embodiments, the step of gradually raising the bookplates after the top layer of bookplates is removed to maintain a constant picking height includes: acquiring the picking status of the top layer of bookplates in the corresponding placement areas of the first lifting and stacking mechanism and the second lifting and stacking mechanism; when it is detected that the top layer of bookplates in the corresponding placement area has been removed, controlling the drive motor of the corresponding lifting and stacking mechanism to drive the screw to rotate, causing the stacking plate to rise vertically along the guide shaft by a distance equal to the thickness of a bookplate, so that the top layer of the remaining bookplates in the corresponding placement area always maintains a preset constant picking height.
