Description

Technical Field

[0001] This invention relates to the field of display screen bonding technology, specifically to an adhesive injection bonding device and a post-injection treatment method for e-ink screen products. Background Technology

[0002] E-ink displays are a type of display device that relies on the reflection of ambient light to display content; they do not have self-emissive capabilities. In environments with sufficient natural light, e-ink displays can clearly display content by reflecting external light. However, in nighttime or low-light environments, due to the lack of sufficient ambient light, they usually require the use of a front light guide plate to ensure the visibility of the displayed content.

[0003] Currently, e-ink displays with front light typically consist of a glass cover, a front light guide plate, and the e-ink display itself, all three usually fully bonded together using a water-based adhesive injection process. This type of structure improves the overall integrity of the product while ensuring display quality, and is therefore widely used.

[0004] However, in actual production, after the product is glued, the water-based glue, due to its fluidity and the influence of factors such as gravity, product placement angle deviation, and handling disturbances, is prone to uneven distribution. When the glue distribution is uneven, the front light guide plate is prone to irregular deformation, which in turn affects the light guiding effect, resulting in uneven brightness and dark areas and poor light emission uniformity in the e-ink screen display area, thus affecting the product display quality.

[0005] Existing technologies typically employ manual methods, using rollers to roll and press the product surface to improve the distribution of internal adhesive. However, this method relies heavily on manual experience, resulting in limited adjustment effectiveness and difficulty in achieving precise control, leading to poor consistency and low processing efficiency. Furthermore, in actual operation, it can easily reduce product yield and increase rework costs, failing to meet the current requirements for product quality and production efficiency in e-ink screen lamination processes.

[0006] In existing technologies, some mechanical glue injection is used. Although the glue filling state can be improved by tilting and rotating during the glue injection process to reduce air bubbles, insufficient glue, or glue waste, for e-ink screen products with front light, after the water-based glue injection is completed, the water-based glue still has fluidity and is affected by gravity, placement angle deviation, and handling disturbances. This can easily lead to uneven redistribution of the internal glue, resulting in irregular deformation of the front light guide plate and uneven display brightness. Summary of the Invention

[0007] This invention provides an adhesive injection bonding device and a post-injection processing method for e-ink screen products, in order to solve the problem in the prior art that after the water-based adhesive injection is completed for e-ink screen products, the water-based adhesive still has fluidity and is easily affected by gravity, placement angle deviation and handling disturbance, which can easily lead to uneven redistribution of the internal adhesive, resulting in irregular deformation of the front light guide plate and uneven brightness of the display.

[0008] In a first aspect, the present invention provides an adhesive injection and bonding device for water-based adhesive bonding processes of e-ink screens; comprising: a support platform, a detection component, and a heating and temperature control component; the support platform is used to support the e-ink screen product after water-based adhesive injection; the detection component is disposed on and / or inside the support platform, and is used to detect the horizontal state and / or posture state of the support platform to determine the distribution state of the adhesive inside the e-ink screen product; the heating and temperature control component is disposed on the support platform, and is used to cure the adhesive after the adhesive distribution inside the e-ink screen product reaches a preset uniform state.

[0009] Beneficial effects: By installing detection components on and / or inside the support platform to detect the horizontal and / or orientation state of the support platform, the internal adhesive distribution of the e-ink screen product after water-based adhesive application is judged. A heating and temperature control component is installed on the support platform. When the internal adhesive distribution of the e-ink screen product reaches a preset uniform state, the adhesive can be cured in a timely manner. This effectively inhibits the re-flow of adhesive during subsequent static placement, handling, or transfer, avoiding irregular deformation of the front light guide plate caused by secondary adhesive flow. It further reduces the risk of uneven brightness and poor light emission uniformity in the e-ink screen display area, thereby improving product display quality and bonding stability. This application integrates the support, detection, and curing functions into a single device, enabling the e-ink screen product to complete state detection and curing locking in the same station or continuous process after water-based adhesive application. This avoids the problems of uneven internal adhesive redistribution caused by gravity, placement angle deviation, and handling disturbances, which can lead to irregular deformation of the front light guide plate and uneven display brightness.

[0010] According to a first aspect of the present invention, the adhesive bonding device further includes a support adjustment assembly, the support adjustment assembly including a bottom support structure, a first support shaft and a second support shaft; the lower ends of the first support shaft and the second support shaft are fixedly connected to the bottom support structure, the first support shaft is rotatably connected to the midpoint of the lower end face of the bearing platform, and the second support shaft is disposed in the edge region of the bearing platform; A first rotating structure is provided between the first support shaft and the bearing platform, and a second rotating structure is provided between the second support shaft and the bearing platform. The bearing platform rotates around the first rotating structure and / or the second rotating structure to adjust the tilt posture of the bearing platform relative to the horizontal plane.

[0011] Beneficial effects: With the support adjustment components installed, the support platform can adjust its tilt relative to the horizontal plane. This allows it to guide the adhesive to flow again and become more evenly distributed when uneven adhesive distribution is detected inside the product. This improves the light guide plate deformation and uneven display brightness caused by uneven adhesive distribution. Furthermore, the first support shaft is rotatably connected to the center of the support platform, and the second support shaft is located at the edge of the platform. This provides the support platform with good stability and adjustment flexibility when adjusting its tilt, which is beneficial for improving the post-application processing effect.

[0012] According to a first aspect of the present invention, the first rotating structure includes a first rotating groove disposed at the bottom of the bearing platform and a first rotating sphere disposed at the top of the first support shaft, the first rotating sphere being rotatably connected to the first rotating groove; The second rotating structure includes a second rotating groove disposed on the edge region of the bearing platform and a second rotating sphere disposed on the top of the second support shaft, the second rotating sphere being rotatably connected to the second rotating groove.

[0013] Beneficial effects: The first rotating structure uses a first rotating groove and a first rotating sphere for rotational connection, and the second rotating structure uses a second rotating groove and a second rotating sphere for rotational connection, creating a spherical rotational fit between the bearing platform and the support shaft. This structure allows the bearing platform to rotate more smoothly when adjusting its tilt posture, reducing jamming and improving the stability and flexibility of posture adjustment. It also helps ensure the support stability of the bearing platform during rotation, thereby improving the controllability and treatment effect of adhesive redistribution after glue injection.

[0014] According to a first aspect of the present invention, the bottom support structure includes a base, a third support shaft, and a connecting plate. The connecting plate is connected to the base via the third support shaft. A through hole is provided in the middle of the connecting plate. The lower end of the first support shaft passes through the through hole and extends to be connected to the base. The lower end of the second support shaft is fixedly connected to the connecting plate. The third support shaft is provided in multiple parts and is located at the corners of the connecting plate. All of the third support shafts can extend and retract in the vertical direction to adjust the height of the bearing platform.

[0015] Beneficial effects: The bottom support structure includes a base, third support shafts, and a connecting plate. Multiple third support shafts are positioned at the corners of the connecting plate and can extend and retract vertically, providing stable support for the load-bearing platform and enabling overall height adjustment. This structure improves the stability of the load-bearing platform during posture adjustment and heat curing processes, reduces the impact of shaking on adhesive distribution, and enhances the device's adaptability to different products and process conditions, thereby improving post-application treatment results.

[0016] According to a first aspect of the present invention, four of each of the second and third support shafts are provided, and the second and third support shafts are coaxially arranged.

[0017] Beneficial effects: Both the second and third support shafts are set to four, and they are coaxially arranged to form a corresponding support relationship between the edge area of ​​the bearing platform and the bottom support structure. This helps to improve the overall force balance and structural stability of the device, reduce the off-center load and sway during the attitude adjustment process, improve the stability and accuracy of the tilt attitude adjustment of the bearing platform, and thus improve the controllability and treatment effect of the glue redistribution after glue injection.

[0018] According to a first aspect of the present invention, the detection component includes a level, which is disposed in the visible area of ​​the support platform and is used to display the level status of the support platform in real time.

[0019] Beneficial effects: The detection component includes a level installed in the visible area of ​​the support platform. The level displays the horizontal status of the support platform in real time, which allows operators to intuitively obtain the status information of the support platform, improves the timeliness and accuracy of judging the distribution of adhesive inside the ink screen product, and reduces the error of human experience judgment, thereby improving the controllability of the post-adhesive injection process and the display quality of the product.

[0020] According to a first aspect of the present invention, the adhesive bonding device further includes a prompting module and a control module disposed on the support platform. The detection component further includes a gyroscope disposed inside the support platform. The gyroscope and the prompting module are both communicatively connected to the control module. The gyroscope is adapted to detect the attitude parameters of the support platform and feed them back to the control module in real time. The control module has a built-in preset range. The control module is adapted to control the prompting module to output prompt information when the attitude of the support platform deviates from the preset range.

[0021] Beneficial effects: By incorporating a gyroscope, a control module, and a prompting module, the gyroscope can detect the attitude parameters of the supporting platform in real time and feed them back to the control module. When the control module determines that the attitude of the supporting platform deviates from a preset range, it controls the prompting module to output a prompt message. This structure enables real-time monitoring and timely alerts for abnormal attitudes of the supporting platform, reducing human judgment errors and improving the controllability and reliability of the post-adhesive application process. This, in turn, helps to improve the problems of light guide plate deformation and uneven display brightness caused by uneven adhesive distribution.

[0022] According to a first aspect of the present invention, the adhesive bonding apparatus further includes an execution module, wherein the execution module and all detection components are communicatively connected to the control module, and the control module is adapted to control the execution module to adjust the support adjustment component in real time according to the posture parameters detected by the detection components.

[0023] Beneficial effects: By setting up an execution module and connecting both the execution module and the detection component to the control module, the control module can control the execution module to adjust the support adjustment component in real time based on the attitude parameters detected by the detection component, thus forming a closed-loop control process combining detection, judgment, and execution. This structure allows for timely correction of the bearing platform's attitude deviation, reducing manual adjustment lag and operational errors, and improving the automation, adjustment accuracy, and consistency of the post-adhesive dispensing process. This, in turn, helps to improve the problems of light guide plate deformation and uneven display brightness caused by uneven adhesive distribution.

[0024] According to a first aspect of the present invention, the heating temperature control assembly includes a heating element and a temperature control element, the temperature control element being used to adjust the heating temperature and / or heating time of the heating element; the heating temperature control assembly is communicatively connected to the control module, the control module being adapted to control the start-up and shutdown of the heating temperature control assembly according to received attitude parameters.

[0025] Beneficial effects: The heating and temperature control assembly includes a heating element and a temperature control element. The temperature control element is used to adjust the heating temperature and / or heating time of the heating element. The heating and temperature control assembly is communicatively connected to a control module, which can control the start and stop of the heating and temperature control assembly based on received attitude parameters. This structure allows the adhesive curing timing to match the attitude state of the supporting platform and adjusts the curing process, thus preventing premature curing of the adhesive before it reaches a relatively uniform distribution. Simultaneously, it ensures timely curing and locking after the adhesive distribution reaches a preset state, reducing secondary adhesive flow and improving post-application processing effects and product display quality.

[0026] Secondly, the present invention also provides a post-treatment method for e-ink screen products after adhesive injection, which, using the adhesive injection and bonding device, includes the following steps: Place the e-ink screen product, after completing the water-based adhesive application, onto the support platform; The horizontal and / or orientation state of the supporting platform is detected by the detection component to determine the uniformity of the adhesive distribution inside the product. When a deviation is detected, the third support shaft at the corresponding position is adjusted to change the tilt state of the bearing platform and / or the bearing platform is rotated and adjusted in orientation by the first and second rotating structures. After detecting that the adhesive distribution inside the product has reached a preset uniform state, the heating and temperature control components are activated to cure the adhesive.

[0027] Beneficial effects: The post-application processing method for e-ink screen products provided in this application uses a detection component to detect the horizontal and / or orientation state of the support platform to determine the uniformity of adhesive distribution inside the product. When a deviation is detected, the third support axis is adjusted and / or the support platform is rotated to guide the adhesive redistribution. After the adhesive distribution reaches a preset uniform state, the heating and temperature control component is activated to cure the adhesive. This method improves the targeting and controllability of adhesive distribution adjustment after application, reduces secondary adhesive flow, and improves issues such as light guide plate deformation and uneven display brightness, thereby enhancing the display quality and bonding stability of e-ink screen products.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1 , Figure 2 and Figure 3 As shown, in a first aspect of the present invention, the present invention provides an adhesive injection bonding device for an e-ink screen water-based adhesive bonding process; comprising: a support platform 1, a detection component 2, and a heating and temperature control component 3; the support platform 1 is used to support the e-ink screen product 5 after water-based adhesive injection; the detection component 2 is disposed on and / or inside the support platform 1, and is used to detect the horizontal state and / or posture state of the support platform 1 to determine the distribution state of the adhesive inside the e-ink screen product 5; the heating and temperature control component 3 is disposed on the support platform 1, and is used to cure the adhesive after the adhesive distribution inside the e-ink screen product 5 reaches a preset uniform state.

[0033] Specifically, by installing a detection component 2 on and / or inside the support platform 1, the horizontal and / or posture states of the support platform 1 are detected, thereby determining the internal adhesive distribution state of the e-ink screen product 5 after water-based adhesive application. A heating and temperature control component 3 is installed on the support platform 1. When the internal adhesive distribution of the e-ink screen product 5 reaches a preset uniform state, the adhesive can be cured in a timely manner, effectively suppressing the re-flow of adhesive during subsequent static placement, handling, or transfer. This avoids irregular deformation of the front light guide plate caused by secondary adhesive flow and further reduces the risk of uneven brightness and poor light emission uniformity in the e-ink screen display area, thus improving product display quality and bonding stability. This application integrates the support, detection, and curing functions into the same device, enabling the e-ink screen product 5 to complete state detection and curing locking in the same station or continuous process after water-based adhesive application. This avoids the problems of uneven internal adhesive redistribution caused by gravity, placement angle deviation, and handling disturbances, which can lead to irregular deformation of the front light guide plate and uneven display brightness.

[0034] In a first aspect embodiment of the present invention, the adhesive bonding device further includes a support adjustment component 4, which includes a bottom support structure 41, a first support shaft 42, and a second support shaft 43. The lower ends of the first support shaft 42 and the second support shaft 43 are fixedly connected to the bottom support structure 41, the first support shaft 42 is rotatably connected to the midpoint of the lower end face of the bearing platform 1, and the second support shaft 43 is disposed in the edge region of the bearing platform 1. A first rotating structure 421 is provided between the first support shaft 42 and the bearing platform 1, and a second rotating structure 431 is provided between the second support shaft 43 and the bearing platform 1. The bearing platform 1 rotates around the first rotating structure 421 and / or the second rotating structure 431 to adjust the tilt posture of the bearing platform 1 relative to the horizontal plane.

[0035] Specifically, by setting up a support adjustment component 4, which includes a bottom support structure 41, a first support shaft 42, and a second support shaft 43, and by using a first rotating structure 421 and a second rotating structure 431, the supporting platform 1 can rotate around the corresponding rotating structures to adjust the tilt posture of the supporting platform 1 relative to the horizontal plane. When the detection component 2 detects uneven glue distribution inside the e-ink screen product 5, the tilt state of the supporting platform 1 can be adjusted to guide the glue to redistribute to the target area using the glue's own fluidity and gravity. This helps to improve the problem of uneven glue distribution after glue application, reduces irregular deformation of the front light guide plate caused by glue imbalance, and lowers the risk of uneven brightness in the e-ink screen display area.

[0036] The first support shaft 42 is rotatably connected to the midpoint of the lower end face of the support platform 1, providing relatively stable central support for the support platform 1. The second support shaft 43 is located in the edge area of ​​the support platform 1 and cooperates with the first support shaft 42, enabling the support platform 1 to adjust its tilt posture while maintaining support stability. This structure not only improves the stability of the support platform 1 during posture adjustment and reduces the interference of platform shaking on glue distribution during adjustment, but also improves the flexibility and adaptability of the tilt adjustment of the support platform 1.

[0037] It is understandable that by cooperating with the support adjustment component 4 and the detection component 2, the posture of the support platform 1 can be adjusted in a targeted manner when a deviation in the glue distribution is detected; and after the glue distribution reaches a preset uniform state, the glue is cured in conjunction with the heating temperature control component 3, which helps to improve the controllability, stability and display quality of the e-ink screen product 5 after glue injection.

[0038] In a first aspect of the present invention, the first rotating structure 421 includes a first rotating groove disposed at the bottom of the bearing platform 1 and a first rotating sphere disposed at the top of the first support shaft 42, the first rotating sphere being rotatably connected to the first rotating groove. The second rotating structure 431 includes a second rotating groove disposed on the edge region of the bearing platform 1, and a second rotating sphere disposed on the top of the second support shaft 43, the second rotating sphere being rotatably connected to the second rotating groove.

[0039] Specifically, by configuring the first rotating structure 421 as a mating structure of the first rotating groove and the first rotating sphere, and configuring the second rotating structure 431 as a mating structure of the second rotating groove and the second rotating sphere, a spherical rotational connection is formed between the first support shaft 42, the second support shaft 43, and the carrier platform 1. When adjusting its tilt posture, the carrier platform 1 can rotate more smoothly relative to the support shaft, reducing interference and jamming during the adjustment process, thereby improving the flexibility and stability of the carrier platform 1's posture adjustment. The structure of the rotating sphere and the rotating groove provides better guidance and support during the rotation of the carrier platform 1, enabling it to rotate in multiple directions while maintaining good connection stability when changing its tilt posture. This helps avoid interference with the flow of adhesive inside the e-ink screen product 5 due to excessive shaking or poor rotation at the connection points, thereby improving the controllability of the adhesive redistribution process after application.

[0040] Understandably, the first rotating sphere and the first rotating groove are positioned between the bottom center of the support platform 1 and the top of the first support shaft 42, while the second rotating sphere and the second rotating groove are positioned between the edge region of the support platform 1 and the top of the second support shaft 43. This configuration enables the support platform 1 to rotate stably with the cooperation of the central and edge supports. This structure not only facilitates the overall force balance of the support platform 1 but also provides better support when adjusting the tilt posture, thereby further improving the deformation reduction effect of the light guide plate and the uniformity of the e-ink screen display.

[0041] In a first aspect embodiment of the present invention, the bottom support structure 41 includes a base 411, a third support shaft 413 and a connecting plate 412. The connecting plate 412 is connected to the base 411 through the third support shaft 413. A through hole is provided in the middle of the connecting plate 412. The lower end of the first support shaft 42 passes through the through hole and extends to be connected to the base 411. The lower end of the second support shaft 43 is fixedly connected to the connecting plate 412. Multiple third support shafts 413 are provided and are located at the corners of the connecting plate 412. All three third support shafts 413 can extend and retract in the vertical direction to adjust the height of the bearing platform 1.

[0042] Specifically, by configuring the bottom support structure 41 to include a base 411, a third support shaft 413, and a connecting plate 412, and connecting the connecting plate 412 to the base 411 via multiple third support shafts 413, the supporting platform 1 can achieve stable support while also adjusting its height by extending and retracting the third support shafts 413 in the vertical direction. Therefore, the overall height of the supporting platform 1 can be flexibly adjusted according to the size, thickness, or processing requirements of different e-ink screen products 5, thereby improving the adaptability of the device to different products and operating conditions.

[0043] Multiple third support shafts 413 are distributed at the corners of the connecting plate 412. Each third support shaft 413 can extend and retract in the vertical direction, providing multi-point support for the connecting plate 412. This structure helps improve the support stability of the bottom support structure 41 on the load-bearing platform 1, reduces the shaking and displacement of the load-bearing platform 1 during posture adjustment or heat curing, and thus avoids adverse effects on the internal adhesive distribution of the e-ink screen product 5 due to unstable support, further improving the stability and controllability of the post-adhesive injection process.

[0044] The lower end of the first support shaft 42 passes through a through hole in the middle of the connecting plate 412 and extends to connect with the base 411, enabling the first support shaft 42 to form a relatively stable central support relationship with the base 411; the lower end of the second support shaft 43 is fixedly connected to the connecting plate 412, enabling the support of the edge area of ​​the bearing platform 1 to cooperate with the connecting plate 412. By combining central support and edge support, it is not only beneficial to ensure a more balanced overall force on the bearing platform 1, but also beneficial to maintain better structural stability when adjusting the tilt posture of the bearing platform 1, thereby improving the treatment effect of guiding the redistribution of glue through posture changes.

[0045] It is understandable that by adjusting the height of the connecting plate 412 through the third support shaft 413, the bearing platform 1 can also have better coordination in the process of overall height and local posture adjustment, which is conducive to the detection component 2 to judge the glue distribution state, and after the glue reaches the preset uniform state, it can cooperate with the heating temperature control component 3 to complete the curing process, thereby improving the display uniformity and bonding quality of the e-ink screen product 5.

[0046] In a first aspect of the present invention, four second support shafts 43 and four third support shafts 413 are provided, and the second support shafts 43 and the third support shafts 413 are coaxially arranged.

[0047] Specifically, by setting four of each of the second and third support shafts 43 and 413, and coaxially oriented, a one-to-one force transmission relationship is established between the support structure at the edge of the bearing platform 1 and the bottom support structure 41. When supporting and adjusting the attitude of the bearing platform 1, the load at the edge of the bearing platform 1 can be more evenly transmitted to the bottom support structure 41, which helps to reduce localized force concentration or off-center loading, and improves overall support stability.

[0048] Understandably, the second support shaft 43 and the third support shaft 413 are coaxially arranged, so that the upper support point corresponds to the lower support point in the vertical direction. This helps to improve the transmission consistency and structural coordination during the support adjustment process, and avoids additional torque, lateral offset, or local swaying caused by misalignment of the upper and lower support positions. When adjusting the tilt posture of the bearing platform 1, it can further improve the stability and accuracy of the posture adjustment, thus making it more conducive to guiding the adhesive inside the e-ink screen product 5 to redistribute in the expected direction.

[0049] Both the second support shaft 43 and the third support shaft 413 are configured as four shafts, corresponding to the corner areas of the bearing platform 1 and the connecting plate 412 respectively, forming a relatively symmetrical multi-point support structure. This structure not only helps to improve the overall stress balance of the bearing platform 1, but also enhances the device's adaptability to e-ink screen products 5 of different sizes or weights, thereby more effectively improving the problems of light guide plate deformation and uneven display brightness caused by uneven glue distribution during the post-glue application process.

[0050] like Figure 3 As shown, in a first aspect embodiment of the present invention, the detection component 2 includes a level 21, which is disposed in the visible area of ​​the support platform 1 and is used to display the horizontal status of the support platform 1 in real time.

[0051] Specifically, the detection component 2 is configured to include a level 21, which is located in the visible area of ​​the support platform 1. The level 21 is used to display the level status of the support platform 1 in real time. Operators can intuitively and timely obtain the current level information of the support platform 1, which facilitates the observation and judgment of the placement status of the ink screen product 5 after glue application. This helps to improve the timeliness and accuracy of judging the distribution status of the glue inside the product.

[0052] Understandably, since the level 21 is located in the visible area of ​​the support platform 1, the operator can directly read the level status information without the need for additional detection equipment. This simplifies the operation process, improves ease of use, and reduces errors caused by relying on human experience.

[0053] The real-time display of the horizontal status of the carrier platform 1 by the level 21 also helps to improve the visualization and controllability of the post-application process of the e-ink screen product 5, so that the carrier platform 1 has clearer status feedback during the bearing, testing and curing process. This helps to reduce the risk of uneven redistribution of glue caused by abnormal platform status, improve the deformation of the front light guide plate and the problem of uneven brightness of the display, and improve the display quality and bonding stability of the product.

[0054] In a first aspect embodiment of the present invention, the adhesive bonding device further includes a prompting module and a control module disposed on the support platform 1. The detection component 2 further includes a gyroscope 22 disposed inside the support platform 1. The gyroscope 22 and the prompting module are both communicatively connected to the control module. The gyroscope 22 is adapted to detect the attitude parameters of the support platform 1 and feed them back to the control module in real time. The control module has a preset range built in, and the control module is adapted to control the prompting module to output prompt information when the attitude of the support platform 1 deviates from the preset range.

[0055] Specifically, by setting up a prompting module and a control module, and installing a gyroscope 22 inside the support platform 1, both the gyroscope 22 and the prompting module are communicatively connected to the control module. The gyroscope 22 can detect the attitude parameters of the support platform 1 in real time and feed the detection results back to the control module. The control module can then compare the detected attitude parameters with a preset range, and control the prompting module to output a prompt message when the attitude of the support platform 1 deviates from the preset range. This structure enables real-time monitoring and anomaly alerts of the attitude status of the support platform 1, thereby improving the timeliness and accuracy of status identification during the post-glue injection processing.

[0056] Compared to methods relying solely on operator visual observation or experience, this application utilizes a gyroscope 22 in conjunction with a control module to automatically identify posture deviations of the supporting platform 1 and provides alerts via a prompting module. This effectively reduces human judgment errors and mitigates the risk of continued adverse adhesive flow due to failure to detect platform posture anomalies in a timely manner. This improves the reliability of adhesive distribution control within the e-ink screen product 5, thereby mitigating irregular deformation of the front light guide plate and uneven display brightness caused by uneven adhesive redistribution.

[0057] Understandably, the built-in preset range in the control module provides a clear judgment standard for the attitude control of the support platform 1. The prompting module outputs a prompt message when the attitude deviates from the preset range, enabling operators to take appropriate measures in a timely manner. This helps to improve the automation, visualization, and controllability of the entire post-application processing, and further enhances the product bonding quality and display consistency.

[0058] In a first aspect of the present invention, the adhesive bonding device further includes an execution module. The execution module and all detection components 2 are communicatively connected to the control module. The control module is adapted to control the execution module to adjust the support adjustment component 4 in real time according to the posture parameters detected by the detection components 2.

[0059] Specifically, by setting up an execution module, both the execution module and the detection component 2 are communicatively connected to the control module. The control module can control the execution module to adjust the support adjustment component 4 in real time based on the attitude parameters detected by the detection component 2. By organically combining the detection, analysis, judgment, and adjustment execution of the attitude state of the bearing platform 1, a closed-loop adjustment process is formed, which helps to improve the automation level and overall controllability of the post-ink coating process of the e-ink screen product 5.

[0060] Compared to relying on manual observation and adjustment of the bearing platform 1's posture, this application uses a control module to receive posture parameters from the detection component 2 in real time and drives the execution module to automatically adjust the support adjustment component 4. This allows for a more timely response to posture deviations of the bearing platform 1, reducing the adverse effects of delayed manual intervention. This helps prevent the adhesive from continuously flowing under abnormal platform posture conditions, thereby improving the control precision of the adhesive redistribution process within the e-ink screen product 5 and further mitigating irregular deformation of the front light guide plate and uneven display brightness caused by uneven adhesive distribution.

[0061] Furthermore, by adjusting the support adjustment component 4 in real time through the execution module, human error and differences in processing between different operators can be reduced, improving the consistency and repeatability of the post-application processing. This setting not only helps improve product display quality and bonding stability but also increases production efficiency and reduces the risk of rework.

[0062] In a first aspect embodiment of the present invention, the heating temperature control component 3 includes a heating element and a temperature control element, the temperature control element being used to adjust the heating temperature and / or heating time of the heating element; the heating temperature control component 3 is communicatively connected to a control module, the control module being adapted to control the start-up and shutdown of the heating temperature control component 3 according to received attitude parameters.

[0063] Specifically, the heating temperature control component 3 is configured to include a heating element and a temperature control element. The temperature control element is used to adjust the heating temperature and / or heating time of the heating element, and the heating temperature control component 3 is communicatively connected to the control module. The control module adjusts the heating parameters during the adhesive curing process according to the actual needs of the post-application treatment of the e-ink screen product 5, thereby making the heating curing process more targeted and adaptable, which is beneficial for meeting the usage requirements of different products, different adhesive states, and different process conditions.

[0064] The control module can control the activation and deactivation of the heating temperature control component 3 based on the received posture parameters. Specifically, it activates the heating temperature control component 3 for curing when the posture of the supporting platform 1 is within a preset range and the adhesive distribution inside the product reaches a suitable state. Conversely, it avoids premature activation of heating if the posture parameters do not meet the preset requirements. This structure allows the adhesive curing timing to match the posture state of the supporting platform 1, preventing curing before the adhesive reaches a relatively uniform distribution, thereby improving the uniformity of adhesive distribution and the final bonding effect.

[0065] Understandably, by adjusting the heating temperature and / or heating time, and combining this with the control module's control over the starting and stopping of the heating temperature control component 3, timely curing and locking can be achieved once the adhesive distribution reaches a preset uniform state, effectively preventing the adhesive from flowing again during subsequent resting, handling, or transfer. This feature helps reduce the risk of irregular deformation of the front light guide plate caused by secondary adhesive flow, and further improves issues such as uneven brightness and poor light emission uniformity in the e-ink display area, thereby enhancing product display quality and bonding stability.

[0066] The heating temperature control component 3 is connected to the control module, enabling the heating and curing process to be linked with the posture detection and prompting process for control. This helps to improve the automation, controllability and consistency of the entire post-application processing, reduce errors caused by manual judgment and operation, thereby improving production efficiency and reducing the risk of rework.

[0067] Secondly, the present invention also provides a post-treatment method for e-ink screen products 5, which utilizes an e-ink bonding device and includes the following steps: Place the e-ink screen product 5, after the water-based adhesive has been applied, onto the support platform 1; The horizontal and / or orientation state of the support platform 1 is detected by the detection component 2 to determine the uniformity of the adhesive distribution inside the product. When a deviation is detected, the third support shaft 413 at the corresponding position is adjusted to change the tilt state of the bearing platform 1 and / or the bearing platform 1 is rotated and adjusted by the first rotating structure 421 and the second rotating structure 431. After detecting that the adhesive distribution inside the product has reached a preset uniform state, the heating and temperature control component 3 is activated to cure the adhesive.

[0068] Specifically, this method involves placing the e-ink screen product 5, after water-based adhesive application, onto a support platform 1. A detection component 2 then detects the horizontal and / or orientation of the support platform 1 to determine the uniformity of the adhesive distribution within the product. This allows for targeted assessment of the adhesive distribution status of the e-ink screen product 5 immediately after adhesive application. Compared to existing technologies that primarily rely on manual experience for post-processing, this method improves the timeliness and accuracy of adhesive distribution assessment.

[0069] When a deviation in the adhesive distribution inside the product is detected, the tilt state of the support platform 1 is changed by adjusting the third support shaft 413 at the corresponding position, and / or the orientation of the support platform 1 is adjusted by rotating it through the first rotating structure 421 and the second rotating structure 431. This allows for corresponding adjustments to the product's placement posture based on the adhesive distribution. Thus, the adhesive's own fluidity and gravity can be used to guide its redistribution towards the target area, thereby improving the irregular deformation of the front light guide plate caused by uneven adhesive redistribution after application and reducing the risk of uneven brightness and poor light emission uniformity in the e-ink display area.

[0070] After detecting that the adhesive distribution inside the product has reached a preset uniform state, the heating and temperature control component 3 is activated to cure the adhesive. This timely locks in the adhesive that has been adjusted to an optimal distribution state, effectively preventing the adhesive from flowing again during subsequent resting, handling, or transfer. This helps reduce the adverse effects of secondary adhesive flow on the bonding effect and further improves the display quality, bonding stability, and yield of the e-ink screen product 5.

[0071] This application's method organically combines detection, posture adjustment, and curing, forming a complete post-processing workflow for e-ink screen products after adhesive application. This method improves the continuity, controllability, and consistency of the post-application process, reduces human error and rework risks, thereby increasing production efficiency and improving overall product quality.

[0072] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
