Description

Technical Field

[0001] This application relates to the field of edge banding for honeycomb sandwich panels, and more specifically, to an edge banding system. Background Technology

[0002] Composite honeycomb sandwich panels are lightweight, high-strength structural materials composed of a panel and a honeycomb core layer. They feature high specific strength, high specific stiffness, and excellent thermal and sound insulation properties, and are widely used in aerospace, rail transportation, shipbuilding, building decoration, and high-end equipment manufacturing. These materials can significantly reduce overall weight and improve structural efficiency while meeting structural load-bearing requirements, making them invaluable in applications demanding both lightweight design and high performance.

[0003] In actual production, edge banding of honeycomb sandwich panels still mainly relies on manual gluing, injection gun filling, and bonding of edge banding strips. This method is inefficient, and the quality of edge banding is greatly affected by the operator's experience and process control level, easily leading to uneven edge banding, air bubbles, voids, and other problems, resulting in poor product quality stability. Furthermore, most existing edge banding equipment is designed for panels with regular dimensions and simple edge shapes, exhibiting poor adaptability and failing to meet the processing needs of honeycomb sandwich panels of different sizes and complex shapes. Especially for honeycomb structures with open perimeters, random distribution, and uneven surfaces, current technology struggles to achieve high-quality, consistent edge banding, failing to meet diverse practical application requirements.

[0004] Therefore, how to provide an edge sealing system that can adapt to honeycomb sandwich panels of different shapes has become a technical problem that needs to be solved in this field. Summary of the Invention

[0012] Preferably, the adhesive coating monitoring device further includes an adhesive coating morphology monitoring structure, which is positioned directly opposite the edge to be sealed of the honeycomb sandwich panel, and is used to obtain the morphology of the adhesive flowing out of the adhesive outlet.

[0013] Preferably, the edge sealing system includes: a monitoring device drive structure, which is connected in cooperation with the adhesive thickness monitoring structure and the adhesive morphology monitoring structure to rotate the adhesive thickness monitoring structure and the adhesive morphology monitoring structure.

[0015] Preferably, the edge sealing system further includes a honeycomb sandwich panel fixing device for placing the honeycomb sandwich panel.

[0016] The edge sealing system in this application monitors the adhesive status in real time through an adhesive monitoring device, collects adhesive status information in real time through a control device, and adjusts the adhesive supply speed and feed speed of the adhesive head device in real time based on the information, thereby achieving full and uniform adhesive filling of the side honeycomb holes of the honeycomb sandwich panel to be sealed, thereby improving the edge sealing quality and structural strength of the honeycomb sandwich panel.

[0017] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0018] The accompanying drawings, which form part of this application, are used to provide a further understanding of this application, and the illustrative embodiments and descriptions thereof are used to explain this application. In the drawings: Figure 1 This is a schematic diagram of the edge sealing system according to this application.

[0019] Figure 2 This is a schematic diagram of the adhesive application head drive structure of the edge banding system according to this application.

[0020] Figure 3 This is a schematic diagram of the driving structure of the monitoring device for the edge sealing system according to this application. Detailed Implementation

[0021] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Currently, edge banding equipment is mostly designed and applied for specific specifications of boards. However, for honeycomb sandwich panels of various sizes and shapes, especially irregularly shaped panels, existing equipment is unable to adjust the edge banding parameters in real time according to the changes in the diameter of the open honeycomb cells. This results in deficiencies in edge banding uniformity, filling fullness, and structural strength after edge banding when dealing with honeycomb cell structures that are highly open, randomly distributed, and have uneven surfaces. Consequently, it affects the overall edge banding quality and product performance.

[0023] Therefore, according to this application, as Figures 1-3As shown, an edge-sealing system is proposed, comprising: an adhesive-applying head device for applying adhesive to the side of a honeycomb sandwich panel to be sealed; an adhesive-applying monitoring device for real-time monitoring of the adhesive state at the adhesive outlet of the adhesive-applying head device; and a control device connected to the adhesive-applying head device and the adhesive-applying head monitoring device via wires, for real-time adjustment of the adhesive supply speed and feed speed of the adhesive-applying head device according to the adhesive state; wherein the adhesive-applying head device and the adhesive-applying monitoring device are integrated at the end of a drive device.

[0024] The aforementioned driving device is a three-axis driving device or a multi-axis robotic arm. The three-axis driving device includes a first linear driving structure, a second linear driving structure, and a third linear driving structure arranged along the X-axis, Y-axis, and Z-axis directions. The second linear driving structure is disposed on the first linear driving structure, and the third linear driving structure is disposed on the second linear driving structure.

[0025] The aforementioned multi-axis robotic arm includes a base, articulated arms, and an end effector. Drive motors are installed at the locations of the articulated arms to achieve multi-degree-of-freedom movement. The number of articulated arms can be set according to actual needs, for example, from 2 to 6 axes.

[0026] The aforementioned edge-sealing system also includes a honeycomb sandwich panel fixing device, which is used to place the honeycomb sandwich panel. During edge sealing, the honeycomb sandwich panel is placed on the honeycomb sandwich panel fixing device. The aforementioned driving device and the honeycomb sandwich panel fixing device can be independent structures. When edge sealing is required, the driving device only needs to move the edge-sealing system above the honeycomb sandwich panel fixing device, or the driving device can be mounted on the honeycomb sandwich panel fixing device. The aforementioned honeycomb sandwich panel fixing device can include a rectangular platform and four support legs, allowing the edge-sealing system to move precisely and smoothly within the area of ​​the honeycomb sandwich panel to be edge-sealed. The aforementioned driving device and the honeycomb sandwich panel fixing device can be fixedly connected or detachably connected, depending on actual needs.

[0027] The aforementioned control device can be a PLC controller or an industrial computer, which can be selected according to actual needs; it can utilize image recognition and parameter control algorithms, etc. The input end of the control device collects data from the pressure sensor, calculates and outputs the sealing parameters.

[0028] Before the edge sealing begins, edge sealing parameters can be preset on the control device, such as the standard pressure for filling the honeycomb cells fully, the glue supply speed and feed speed of the glue applicator; in addition, the drawings of the honeycomb sandwich panel can be uploaded to the control device.

[0029] The aforementioned control device can collect the adhesive status from the adhesive monitoring device in real time, thereby judging the edge sealing status and automatically adjusting the adhesive supply speed and feed speed of the adhesive head device, so that the side honeycomb holes of the honeycomb sandwich panel to be sealed are filled with adhesive fully and evenly, thereby improving the edge sealing quality and structural strength of the honeycomb sandwich panel.

[0030] To apply adhesive to the side of the honeycomb sandwich panel to be sealed, the adhesive application head device preferably includes: an adhesive application head 1, which has an adhesive outlet on its side for applying adhesive to the side of the honeycomb sandwich panel to be sealed; and an adhesive supply structure 2, the first end of which is connected to an external adhesive supply pipeline, and the second end which is movably connected to the adhesive application head 1 and internally connected, for supplying adhesive to the honeycomb sandwich panel to be sealed. The adhesive application head 1 can have an appropriate shape, such as a cylinder, with the adhesive outlet located on the bottom side of the adhesive application head 1, and the height of the adhesive outlet being the same as the thickness of the honeycomb sandwich panel, so as to facilitate the adhesive application head 1 supplying adhesive to the honeycomb sandwich panel. The top opening of the aforementioned glue supply structure 2 is connected to the external glue supply pipeline, and the bottom opening is connected to the glue application head 1. The diameter of the internal glue supply pipeline of the glue supply structure 2 gradually decreases from top to bottom, for example, it can be a conical or tapered structure, thereby changing the flow channel cross-section of the internal glue supply pipeline, optimizing the flow state and pressure distribution of the glue, and thus improving the stability and controllability of the glue supply process. The aforementioned glue application head 1 and glue supply structure 2 are movably connected, so that the direction of the glue application head 1 can be adjusted according to the area to be sealed in the honeycomb sandwich panel.

[0031] To ensure the stability of adhesive dispensing from the adhesive supply structure 2, preferably, the sealing system may further include a pressure detection device 3, which is disposed in the adhesive application head device to collect the adhesive pressure in the adhesive application head device in real time. To obtain adhesive pressure closer to the dispensing port, the pressure detection device 3 may be disposed on the adhesive application head 1. In this application, to facilitate rotation of the adhesive application head 1, an opening is provided on the side of the bottom end of the adhesive supply structure 2 to facilitate real-time monitoring of the instantaneous adhesive pressure by the pressure detection device 3. The pressure detection device 3 is a pressure sensor and is electrically connected to the control device.

[0032] The pressure sensor feeds back the instantaneous pressure signal of the adhesive to the control device, which is then compared with the standard pressure obtained from previous tests when the honeycomb cells are fully filled. When the instantaneous pressure is lower than the standard pressure, it indicates that the honeycomb cells are too large and not fully filled. If the operation continues according to the preset sealing parameters, problems such as the honeycomb cells not being fully filled, or the sealing surface being concave, or lateral adhesive shortages may occur. In this case, the feed speed of the adhesive head 1 should be reduced or the adhesive supply speed should be increased. When the instantaneous pressure is higher than the standard pressure, it indicates that the honeycomb cells are too small and have been filled. If the operation continues according to the preset sealing parameters, problems such as the sealing surface being convex or even adhesive overflow may occur. In this case, the feed speed of the adhesive head 1 should be increased or the adhesive supply speed should be reduced.

[0033] To ensure that the adhesive outlet of the adhesive applicator 1 always faces the honeycomb cells to be filled during the edge sealing process, the edge sealing system preferably includes an adhesive applicator drive structure, which is movably connected to the adhesive applicator 1 and is used to rotate the adhesive applicator 1. In a preferred embodiment, the adhesive application head drive structure includes: an adhesive application head drive motor 4, which is fixedly mounted to the adhesive supply structure 2; a first drive gear 5 for the adhesive application head, which is located at the bottom of the adhesive application head drive motor 4; and a second driven gear 6 for the adhesive application head, which is located at the top of the adhesive application head 1 and meshes with the first drive gear 5. The second driven gear 6 is used to drive the adhesive application head to rotate, and the control device controls the adhesive application head drive motor 4 according to the honeycomb sandwich panel drawing to drive the first drive gear 5 to drive the second driven gear 6, thereby allowing the adhesive application head 1 to automatically rotate. This ensures that the adhesive outlet always faces the honeycomb to be filled during the edge sealing process, thus enabling the edge sealing system to adapt to honeycomb sandwich panels of different sizes and shapes.

[0034] To improve the edge sealing quality of the honeycomb sandwich panel, preferably, the adhesive coating monitoring device may include an adhesive coating thickness monitoring structure 7, which is positioned directly opposite the edge to be sealed position of the honeycomb sandwich panel and is used to monitor the thickness of the adhesive flowing from the adhesive outlet of the adhesive coating monitoring device.

[0035] The aforementioned adhesive thickness monitoring structure 7 can be a laser rangefinder, which is set on the adhesive head 1 via an adapter plate 12. The measuring point of the adhesive thickness monitoring structure 7 is aligned with the front side of the adhesive outlet (the area to be sealed) to measure the thickness of the adhesive flowing out of the outlet.

[0036] The control device calculates the instantaneous glue thickness based on the distance of the glue flowing from the glue outlet measured by the laser rangefinder. It then compares this instantaneous glue thickness with the standard thickness corresponding to the sealing quality of the honeycomb holes in the control device. If the instantaneous glue thickness is lower than the standard thickness, it indicates that the glue output is insufficient, and the feeding speed of the glue head 1 should be reduced or the glue supply speed should be increased. If the instantaneous glue thickness is higher than the standard thickness, it indicates that the sealing surface is about to bulge or has already bulged, and the feeding speed of the glue head 1 should be increased or the glue supply speed should be reduced.

[0037] Preferably, the adhesive coating monitoring device may further include an adhesive coating morphology monitoring structure 8, which is positioned directly opposite the edge to be sealed of the honeycomb sandwich panel and is used to monitor the morphology of the adhesive flowing out of the adhesive outlet.

[0038] The aforementioned adhesive coating morphology monitoring structure 8 can be a vision camera, and the adhesive morphology includes the adhesive outline. The vision camera is mounted on the adhesive coating head 1 via an adapter plate 12 to capture an image of the adhesive outline flowing out of the dispensing port. The adhesive coating morphology monitoring structure 8 and the adhesive coating thickness monitoring structure 7 are mounted on the same adapter plate 12 so that both can monitor the adhesive outline and thickness at the dispensing port in real time from the same angle. The adhesive coating morphology monitoring structure 8 can acquire the overall situation of the adhesive flowing out of the dispensing port and coating the honeycomb, including adhesive shortage and adhesive overflow.

[0039] The control device uses the image of the adhesive application pattern and software such as OpenCV for image processing to extract the adhesive outline, calculate the instantaneous adhesive area, compare it with the standard adhesive area corresponding to the required sealing quality, and analyze its morphological characteristics to determine if there will be insufficient or excessive adhesive: when the instantaneous adhesive area is lower than the standard area, or the adhesive width is significantly lower than the width of the honeycomb groove, it indicates insufficient adhesive output, and the feeding speed of the adhesive application head 1 should be reduced or the adhesive supply speed should be increased; when the instantaneous adhesive area is higher than the standard area, or the adhesive pattern shows a tendency to bulge or drip on both sides, the feeding speed of the adhesive application head 1 should be increased or the adhesive supply speed should be reduced.

[0040] To better monitor the thickness and shape of the adhesive at the dispensing port, the sealing system preferably includes: a monitoring device drive structure, which is connected to the adhesive thickness monitoring structure 7 and the adhesive shape monitoring structure 8 to rotate the adhesive thickness monitoring structure 7 and the adhesive shape monitoring structure 8. Preferably, the monitoring device drive structure includes: a monitoring device drive motor 9, which is fixedly mounted to the adhesive supply structure 2 of the adhesive head device; a first driving gear 10, which is located at the bottom of the monitoring device drive motor 9; and a second driven gear 11, which is located at the top of the adhesive thickness monitoring structure 7 and the adhesive shape monitoring structure 8, meshing with the first driving gear 10, to drive the adhesive thickness monitoring structure 7 and the adhesive shape monitoring structure 8 to rotate via the monitoring device drive motor 9.

[0041] The pressure detection device 3, adhesive thickness monitoring structure 7, and adhesive morphology monitoring structure 8 mentioned above can be used individually, in combination, or all three at the same time.

[0042] The control method for the edge banding of the above edge banding system is as follows: 1. For scenarios where consistent edge banding quality is required and a certain level of computational complexity is acceptable.

[0043] Set the confidence weights Wp, Wh, and Wv for the pressure sensor, laser rangefinder, and vision camera (e.g., 0.3, 0.4, 0.3). Calculate the overall weighted decision value D. D = Wp × pressure deviation + Wh × thickness deviation + Wv × adhesive area deviation Deviation value = Actual measured value - Preset value If D is less than the lower limit of the overall weighted decision value, the final decision is to either increase the amount of glue dispensed or decrease the feed speed of the coating head.

[0044] If D is greater than the upper limit of the overall weighted decision value, then the final decision is to reduce the amount of glue dispensed or increase the feed speed of the coating head.

[0045] Otherwise, make the final decision to maintain the current parameters.

[0046] 2. For scenarios where real-time control response is critical and adhesive thickness is determined to be the most critical quality indicator.

[0047] In this scenario, the adhesive thickness is used as a continuously adjustable variable, while the adhesive pressure and adhesive area are used as safety boundary constraint variables.

[0048] The system calculates the instantaneous adhesive thickness using adhesive distance data and compares it to the standard thickness corresponding to the required edge sealing quality. If the instantaneous adhesive thickness is lower than the standard thickness, it indicates insufficient adhesive dispensing, requiring a reduction in the adhesive head 1 feed speed or an increase in the dispensing speed. If the instantaneous adhesive thickness is higher than the standard thickness, it indicates that the edge sealing surface is about to bulge or has already bulged, requiring an increase in the adhesive head 1 feed speed or a decrease in the dispensing speed. The system will adjust the process parameters linearly based on the magnitude of the deviation. For example: the increase in adhesive head feed speed = proportional coefficient × thickness deviation.

[0049] In this strategy, the instantaneous pressure at dispensing (adhesive pressure) and the visual signal (adhesive area) are not involved in continuous control, but are only used for safety monitoring.

[0050] Set the lower and upper limits for adhesive pressure: If the adhesive pressure is below the lower limit, it indicates that the internal filling is extremely insufficient and there is a risk of large-area cavities. At this time, forceful adhesive increase is immediately triggered to significantly reduce the feed speed of the laminating head or increase the supply speed until the adhesive pressure rises back to the safe range. If the adhesive pressure is above the upper limit, it indicates that the internal filling is complete and the resistance is too high, and there is a risk of adhesive bursting or serious adhesive overflow at any time. At this time, forceful adhesive reduction is immediately triggered to significantly increase the feed speed of the laminating head or decrease the supply speed until the adhesive pressure falls back to the safe range.

[0051] Set a safe lower and upper limit for the adhesive area, and define clear characteristics of adhesive overflow (such as edge dripping): If the adhesive area is below the lower limit or "the adhesive width is significantly smaller than the honeycomb groove" is identified, it indicates that there is a lateral adhesive shortage. Forced adhesive increase is triggered immediately; if the adhesive area is above the upper limit or "a clear adhesive overflow pattern" is identified, it indicates that adhesive overflow has occurred or is about to occur, and forced adhesive reduction is triggered immediately.

[0052] The command priority is: forced command (from the upper or lower limit protection of adhesive pressure or adhesive area) > thickness linear adjustment command. That is, when the system is performing linear adjustment based on thickness deviation, once the adhesive pressure or adhesive area triggers a forced command, the current linear adjustment is immediately interrupted and the forced command is executed. After the conditions for triggering the forced command are removed (adhesive pressure and adhesive area return to the safe range), the system resumes thickness-based linear control.

[0053] Before the formal edge sealing begins, extensive edge sealing tests are conducted to obtain basic data that enables high-quality edge sealing of the honeycomb panels. This data is then used as the system's preset process parameters to begin the edge sealing process. During the edge sealing process, the control device software collects and analyzes sensor data (adhesive pressure, adhesive profile) in real time, and dynamically adjusts parameters according to the adhesive coating pattern.

[0054] The system records complete sensor data sequences, executed control strategies, adjustment actions, and subsequent quality data (such as final inspection results). This data can be used to optimize parameters in each strategy, such as the weights and thresholds of Strategy 1, and the adjustment ratio coefficients and safety upper and lower limits of Strategy 2. It can also be used to recommend the most suitable control strategies and initial parameters for different cellular panel characteristics (such as cell aperture and profile curvature) through machine learning models, achieving intelligent scheduling.

[0055] The preferred embodiments of this application have been described in detail above. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.

[0056] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0057] Furthermore, various different embodiments of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed by this invention.
