However, due to the confined space at the blade tip, operators cannot easily access the narrow area to completely remove the extruded glue, resulting in long-term retention of the extruded glue generated during the bonding process. During wind farm operation, the extruded glue is prone to detachment, causing blade damage. This method suffers from problems such as limited coverage of manual glue removal, poor blade forming quality, and potential safety hazards during service operation. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] During the molding process of wind turbine blades, the bonding between the web and the blade skin involves primary and secondary bonding steps. A large amount of excess structural adhesive is extruded during the curing process. Currently, the industry commonly uses manual adhesive removal, where operators clean the extruded adhesive at the bonding area between the web and the skin. However, due to the confined space at the blade tip, operators cannot easily access this narrow area to completely remove the extruded adhesive. This results in the adhesive remaining for extended periods, which can easily detach and damage the blade during wind farm operation. This presents problems such as limited coverage for manual adhesive removal, poor blade molding quality, and potential safety hazards during operation.

[0028] In view of this, the adhesive receiving method, adhesive collection device, and wind turbine blade provided in this application are as follows: The adhesive receiving method includes a web preparation step, an adhesive preparation step, an adhesive collection device step, and an adhesive collection step. By setting a guide extending along the length of the web body, the connector of the adhesive collection device can be detachably connected to the guide and can move along the length, effectively covering the entire length of the wind turbine blade, thereby reaching the narrow tip area that is difficult for manual removal and solving the problem of limited coverage of manual adhesive removal. In the adhesive collection step, the control component acquires the actual posture information of n target collection areas (n≥2), compares it with the target posture information to adjust the working posture of the adhesive collection component, ensuring that the adhesive collection component adheres to the flange and skin bonding area, efficiently scraping and collecting the adhesive to be removed, and avoiding long-term retention of extruded adhesive. This improves the bonding and molding quality of the wind turbine blade, effectively avoids damage to the wind turbine blade caused by the detachment of retained adhesive during wind farm operation, and replaces manual adhesive collection, significantly improving collection efficiency and operational consistency, and reducing manual operation costs and difficulty.

[0029] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] See Figure 1 This application provides a method for bonding and receiving adhesive to a wind turbine blade 10, comprising: S100: Providing a web plate 12 step, the web plate 12 includes a web plate body 12a and a guide member 12b. The web plate body 12a has a first end and a second end opposite to each other along its own height direction X. The first end and the second end are provided with flanges 121a. The guide member 12b is connected to the web plate body 12a and is located between the first end and the second end. The guide member 12b extends along the length direction of the web plate body 12a.

[0031] In other words, the web body 12a itself forms a first end and a second end that are arranged opposite to each other along the height direction X. The first end and the second end are respectively provided with flanges 121a. The flanges 121a can be integrally formed by the web body 12a, which can provide a stable mating basis for subsequent bonding with the skin of the wind turbine blade 10 shell 11.

[0032] The guide member 12b is integrally assembled on the web body 12a, specifically between the first end and the second end. The extension direction of the guide member 12b is the same as the length direction of the web body 12a itself. This facilitates the smooth movement of the glue collection device 30 along its length, adapting to the passage operations in different areas of the wind turbine blade 10, especially in confined spaces. For example, the extension length of the guide member 12b is equal to the extension length of the web body 12a.

[0033] The guide component 12b and the web body 12a are reliably connected by a suitable assembly method, and can be firmly attached to the surface of the web body 12a, forming a reference track for the glue collection device 30 to move and cooperate with the web body 12a. Through the reasonable structural layout of the web body 12a, the flange 121a and the guide component 12b, the flange 121a can meet the needs of subsequent adhesive application and skin docking assembly, while the guide component 12b, which extends in the same direction, provides structural support for the subsequent detachable assembly and free movement along the length direction of the glue collection device 30, thereby providing structural guarantee for the attitude adjustment and all-area position glue collection operation of the subsequent glue collection device 30, and adapting to the working condition adaptability requirements of the wind turbine blade 10 integral molding.

[0034] Optionally, the molding substrate of the guide 12b may include polyvinyl chloride (PVC), polyethylene terephthalate (PET), glass fiber reinforced polyamide, glass fiber reinforced polycarbonate, acrylonitrile-butadiene-styrene copolymer (ABS), aluminum alloy, fiberglass, carbon fiber reinforced, foam core composite plastic, thermoplastic fusible material, etc.

[0035] Optionally, the guide member 12b may include a guide rail, which may include a T-shaped guide rail, a dovetail guide rail, an I-shaped guide rail, a semi-circular guide rail, a double-convex rib guide rail, a single-sided snap-fit ​​guide rail, an embedded convex rib guide rail, or other cross-sectional forms that can achieve sliding guidance.

[0036] Optionally, the guide component 12b can be integrally cast with the web body 12a after being produced separately. Alternatively, the guide component 12b and the web body 12a can be produced separately and then connected and fixed by means of bonding, bolting, riveting, etc. Or, the web body 12a and the guide component 12b can be integrally formed using a mold. The embodiments of this application are not limited here.

[0037] In some alternative embodiments, the web body 12a itself may be directly machined to form the guide 12b, or some web bodies 12a may have reinforcing ribs, which may serve as guides 12b.

[0038] In other alternative embodiments, the guide member 12b can also serve as a flow carrier and a lightning protection structure fixing seat, thereby integrating the functions of guidance, flow diversion and lightning protection structure fixing into one, simplifying the internal structural layout of the wind turbine blade 10, reducing the number of parts assembled, and reducing production and assembly costs.

[0039] S200: Bonding step, the flange 121a is bonded to the skin of the housing 11 of the wind turbine blade 10 with adhesive, the adhesive including the adhesive to be removed protruding from the flange 121a.

[0040] In practice, the flange 121a can be used as the bonding reference point. Adhesive is evenly distributed between the flange 121a and the skin of the shell 11 at their contact interface. The adhesive properties of the adhesive enable a secure and stable connection between the flange 121a and the skin, forming a reliable integrated assembly structure between the web 12 and the wind turbine blade 10 shell 11. During the bonding process between the flange 121a and the skin, due to the assembly gap and the distribution of the adhesive coating, some adhesive may overflow and extend outwards from the bonding seam, protruding from the outer contour surface of the flange 121a, thus forming adhesive to be removed.

[0041] S300: Providing a glue collection device 30 step, the glue collection device 30 includes a connector 100, a glue collection member 200 connected to the connector 100, and a control component 300, wherein the connector 100 is detachably connected to the guide member 12b, and the connector 100 has a degree of freedom of movement along the length direction relative to the guide member 12b.

[0042] It should be noted that the collecting component 200 is securely mounted on the connecting component 100 and can move synchronously with the connecting component 100. The control component 300 is integrated into the collecting device 30, providing functional support for subsequent posture information acquisition, data comparison, and operation posture adjustment. The connecting component 100 serves as the connecting structure between the collecting device 30 and the guide component 12b, and is installed in a detachable assembly form with the guide component 12b, enabling convenient assembly and subsequent disassembly. The connecting component 100 and the guide component 12b form a sliding fit, allowing the connecting component 100 to smoothly slide freely along the length of the web body 12a, relying on the extension direction of the guide component 12b, possessing stable and reliable degrees of freedom of movement. With the limiting and guiding effect of the guide component 12b, the connector 100 can drive the glue collection device 30 to move synchronously along the length direction, which can cover different deployment areas of the wind turbine blade 10, providing a reliable assembly structure and motion basis for subsequent regional attitude information collection and completion of overflow glue scraping and collection operations.

[0043] Since the glue collection device 30 can be formed into the main body of the glue collection operation by means of the connector 100, the glue collection component 200 and the control component 300, the overall layout is simple and compact, which can achieve the effect of miniaturization. Therefore, with the help of the guide component 12b, it can smoothly enter narrow areas to collect glue, effectively making up for the shortcomings of manual operation in limited spaces such as the tip of the blade.

[0044] In some embodiments, since the glue collection device 30 is provided with a control component 300, the control component 300 can generate positioning data of the web body 12a relative to the skin by acquiring the vertical distance between the glue collection component 200 along the thickness direction Y of the web body 12a and the web body 12a, and the vertical distance between the glue collection component 200 along the height direction X and the skin. The glue collection device 30 can also serve as a positioning mechanism in the web 12 bonding step.

[0045] S400: Glue collection step. Along the length direction, the wind turbine blade 10 has n target collection areas, n≥2. The glue collection device 30 is controlled by the control component 300 to move along the length direction relative to the guide 12b and to sequentially acquire the actual posture information of the glue collection device 30 in the corresponding target collection area. The working posture of the glue collection device 30 relative to the flange 121a and the skin is adjusted according to the difference between the actual posture information and the target posture information, so that the glue collection component 200 moves along the length direction with the connector 100 to scrape off and collect the glue to be removed.

[0046] It should be noted that dividing the wind turbine blade 10 into n target acquisition areas along its length can be understood as dividing the blade into several working areas along its length. When the adhesive collection device 30 moves to each target acquisition area, the control component 300 acquires the actual posture information of the adhesive collection device 30 at a fixed point. In addition, the actual posture information can be continuously and in real time acquired during the movement of the adhesive collection device 30. This setup can comprehensively cover the bonding areas at different positions of the blade, ensuring that the adhesive collection operation is thorough. During the adhesive collection operation, the control component 300 of the adhesive collection device 30 controls the connector 100 to drive the entire adhesive collection device 30 to move smoothly along the extension direction of the guide 12b. Within each target acquisition area, the control component 300 acquires the actual posture information of the adhesive collection device 30, which corresponds to the relative position and contact state between the adhesive collection component 200 and the web body 12a and skin. Subsequently, the control component 300 compares the collected actual posture information with the preset target posture information, calculates the difference between the actual posture information and the target posture information, and adjusts the working posture of the glue collection device 30 relative to the flange 121a and the skin according to the difference, ensuring that the glue collection component 200 is always in a suitable working state. On this basis, the glue collection component 200 moves continuously along the length direction with the connecting component 100, simultaneously completing the scraping operation of the glue to be removed, and collecting the scraped glue in a timely manner, effectively avoiding glue residue or fall-off, and providing a guarantee for the molding quality and subsequent service safety of the wind turbine blade 10. In addition, the glue collection device 30 can also replace manual glue collection, thereby improving glue collection efficiency and shortening the production cycle of the wind turbine blade 10.

[0047] Optionally, the glue-collecting device 30 can perform the glue-collecting step from the blade tip to the blade root, or from the blade root to the blade tip. In some optional embodiments, two glue-collecting devices 30 can be mounted on the same guide member 12b, whereby the two glue-collecting devices 30 can be respectively located at the blade root and the blade tip, performing the glue-collecting step in a direction toward each other; or they can be located in the middle region, so that the two glue-collecting devices 30 can perform the glue-collecting step in a direction away from each other. This embodiment of the application does not impose any limitations on this.

[0048] In some alternative embodiments, after the glue removal step, the guide 12b may also retain its connection with the web body 12a, thereby providing additional support to the web body 12a to improve the bending stiffness of the web 12.

[0049] In some embodiments, after the glue removal step, at least a portion of the guide 12b is detached from the web body 12a.

[0050] In practice, the guide component 12b can be a segmented structure along the length of the wind turbine blade 10. Operators can disassemble the portion of the guide component 12b near the blade root, effectively reducing the redundant weight of the wind turbine blade 10 and achieving a lightweight design. However, in the area near the blade tip, due to the limited space, some of the guide component 12b can be retained.

[0051] See Figure 1 and Figure 2 In some embodiments, a web plate 12 forming step is included before the web plate 12 providing step. S500: The web plate 12 forming step includes: S510: Provides a forming mold for the web 12, the forming mold including a mold body 21 and a groove 22 disposed in the mold body 21.

[0052] S520: Lay out structural layer 23 inside the molding die.

[0053] S530: A vacuum membrane is laid on the side of the structural layer 23 away from the molding die, and the cavity between the vacuum membrane and the structural layer 23 is controlled to be in a vacuum state. Filler material is poured in and cured to form the web 12.

[0054] The structural layer 23 may include fiberglass mat, fiberglass cloth, composite fiber woven fabric, core material, lightning protection wire, etc.

[0055] It should be noted that by setting the groove 22, it is easier to lay the structural layer 23 of the flange 121a.

[0056] It should also be noted that step S530 can be understood as forming a closed cavity by laying a vacuum membrane and creating a vacuum environment. Under negative pressure, the filling material is guided to permeate evenly into all parts of the structural layer 23, and the whole is solidified and shaped, effectively reducing internal bubbles and delamination defects, and improving the overall density and structural mechanical properties of the web 12.

[0057] See Figure 3 In some embodiments, the molding die further includes a guide female mold 24, which is disposed inside the groove 22 and is used to accommodate the guide 12b; The step of laying the structural layer 23 in the molding die includes: laying a non-porous membrane in the guide mold 24, providing at least one guide 12b, setting the guide 12b in a preset position, and laying the structural layer 23 in the molding die, wherein the guide 12b is fitted to the structural layer 23, and the preset position includes the side of the guide mold 24 and / or the structural layer 23 away from the molding die.

[0058] To achieve integral casting of the guide member 12b and the web body 12a, and to ensure the reliability of their connection and structural integrity, the molding die may further include a guide member female mold 24. This guide member female mold 24 is designed to fit the guide member 12b and is located inside the groove 22 of the molding die. Its interior forms a cavity matching the shape of the guide member 12b, used to accommodate and position the guide member 12b. In the specific implementation of the step of laying the structural layer 23 inside the molding die, a non-porous membrane must first be laid on the inner wall of the cavity of the guide member female mold 24, ensuring that the non-porous membrane adheres to the inner wall of the cavity. This prevents the subsequent filling material from seeping into the interior of the guide member female mold 24, ensuring the structural integrity of the guide member 12b and the ease of subsequent demolding. Subsequently, the guide member 12b is arranged in a preset position. This preset position can be inside the cavity of the guide member female mold 24, or on the side of the structural layer 23 away from the molding die, or the guide member 12b can be arranged in both positions simultaneously. While laying the guide component 12b, the structural layer 23 of the web body 12a can be laid. After the guide component 12b is laid, a vacuum membrane can be laid on the side of the structural layer 23 away from the molding mold. The cavity between the vacuum membrane and the structural layer 23 is controlled to be in a vacuum state. The filling material is poured in and cured, so that the guide component 12b, the structural layer 23 and the filling material are cured and formed simultaneously. This achieves the integral injection molding of the guide component 12b and the web body 12a, improves the firmness of the connection between the two, and simplifies the subsequent assembly process of the guide component 12b.

[0059] In some embodiments, the step of providing the molding die for the web 12 further includes a molding step for the guide mold 24, the molding step for the guide mold 24 including: A structural layer 23 with flange 121a is laid in the groove 22, and a non-porous membrane is laid in the mold body 21 and the groove 22; A female mold forming material is poured between the groove 22 and the non-porous membrane; The guide 12b is placed in the groove 22 to remove excess female mold forming material; The molding die is heated to a preset temperature and kept at that temperature for a preset time. Remove the guide 12b and the non-porous membrane to form the guide female mold 24.

[0060] In practice, to ensure that the guide mold 24 can adapt to the external dimensions of the guide 12b and guarantee the reliability of the subsequent integral casting of the guide 12b and the web body 12a, the step of providing the molding mold for the web 12 also includes the molding step of the guide mold 24. First, inside the groove 22 of the molding mold, the structural layer 23 corresponding to the flange 121a is laid according to the preset configuration of the flange 121a, ensuring that the structural layer 23 is attached to the inner wall of the groove 22. Then, a non-porous membrane is laid on the surface of the mold body 21 and the inner wall of the groove 22 to isolate and prevent adhesion, thus avoiding adhesion between the subsequent mold molding material and the mold body 21 and the flange 121a structural layer 23. Afterwards, the mold molding material is slowly poured into the gap between the groove 22 and the non-porous membrane, ensuring that the material evenly fills the gap. After injection, the guide 12b is placed in the groove 22. The excess molded material is removed by squeezing out the shape of the guide 12b, causing it to conform to the outer surface of the guide 12b, forming a cavity that fits the guide 12b. Excess molded material is then scraped off along the surface of the mold body 21 to effectively prevent the guide mold 24 from protruding from the mold body 21. Subsequently, the entire mold is heated to a preset temperature and maintained for a preset time to ensure the molded material fully solidifies, forming a stable and precisely contoured mold prototype. After solidification, the guide 12b and the laid non-porous membrane are removed. The remaining solidified molded material in the groove 22 forms the guide mold 24, which meets the requirements for subsequent positioning and integral injection molding of the guide 12b.

[0061] Optionally, the female mold material may include silicone. The preset temperature can be 75°C, and the holding time can be 6 hours.

[0062] In some optional embodiments, the guide mold 24 can also be manufactured by various methods such as 3D printing, CNC machining, hot pressing, prefabricated plastic insert molding, and direct machining on the mold body 21. Similarly, the guide 12b can also be manufactured by processes such as 3D printing, CNC machining, compression molding, and injection molding of prefabricated composite parts.

[0063] In some embodiments, along the height direction X of the molding die, the inner wall of the groove 22 on one side for laying the flange 121a structural layer 23 has a minimum gap with the guide member 12b, the minimum gap being h, wherein 10mm≤h≤30mm.

[0064] Optionally, h=10mm, h=15mm, h=20mm, h=30mm, etc.

[0065] It should be noted that, along the height direction X of the molding die, there is a minimum gap between the inner wall of the groove 22 on one side used for laying the flange 121a structural layer 23 and the guide member 12b. Therefore, when the guide member 12b and the web body 12a are processed using an integrated injection molding process, this minimum gap provides sufficient working space, facilitating the laying of the structural layer 23 at the flange 121a and preventing the guide member 12b from being placed too close, encroaching on the working space and causing wrinkles, misalignment, or dead corners in the laying of the structural layer 23. Simultaneously, this minimum gap setting balances the convenience of the molding process with the rationality of the structural layout, ensuring that the flange 121a structural layer 23 is laid flat and densely without affecting the subsequent sliding guidance function of the guide member 12b for the glue collection device 30, thus adapting to the overall molding and subsequent glue collection requirements of the wind turbine blade 10.

[0066] See Figure 4 and Figure 5 In some embodiments, the housing 11 includes a skin that surrounds and forms a cavity 11a, the skin including a windward skin 11b and a leeward skin 11c, and the bonding step includes a primary bonding step and a secondary bonding step. S210: The bonding step includes bonding one side flange 121a of the web 12 to one of the windward skin 11b and the leeward skin 11c.

[0067] S220: The secondary bonding step includes: flipping the other of the windward skin 11b and the leeward skin 11c and aligning and bonding it with the other side flange 121a of the web 12.

[0068] The process includes providing the adhesive collection device 30 and collecting the adhesive after the first bonding step and before the second bonding step, and also includes providing the adhesive collection device 30 and collecting the adhesive after the second bonding step.

[0069] In other words, one side flange 121a of the web 12 can be first fixedly connected to either the windward skin 11b or the leeward skin 11c using adhesive, thus initially positioning the web 12 on the skin. After the first bonding step is completed and before the second bonding step begins, the steps of providing the adhesive collection device 30 and collecting adhesive are performed to promptly remove excess adhesive generated during the first bonding process. After completing the above adhesive collection operation, the second bonding step is performed. The other of the windward skin 11b and the leeward skin 11c that was not bonded in the first bonding step is flipped to the corresponding position, aligned with the other side flange 121a of the web 12, and then bonded to fix the web 12 to the skin of the shell 11. After the second bonding step is completed, the steps of providing the adhesive collection device 30 and collecting adhesive are performed again to clean up excess adhesive generated during the second bonding process, ensuring the regularity of the overall structure and preventing residual adhesive from affecting the stability of the blade in subsequent use.

[0070] In addition, by promptly scraping off and collecting the excess adhesive that overflows from the protruding flange 121a during the bonding process, the excess structural adhesive can be recycled, reducing waste and effectively lowering material consumption and manufacturing costs. At the same time, it avoids the accumulation of residual adhesive from affecting the flatness of the skin surface, ensuring the structural regularity and long-term service stability of the blade bonding area.

[0071] In some alternative embodiments, the step of providing the adhesive collection device 30 after a bonding step can also be replaced by providing the adhesive collection device 30 before a bonding step.

[0072] In some embodiments, the actual posture information includes at least one of the following: the vertical distance between the take-up member 200 and the web body 12a along the thickness direction Y; the tilt angle of the take-up member 200 relative to the skin; and the contact pressure between the take-up member 200 and the skin. The target posture information includes at least one of the following: the preset vertical distance; the preset tilt angle; and the preset contact pressure.

[0073] It should be noted that, in order to achieve precise adjustment of the working posture of the adhesive collection device 30 and ensure the uniformity and completeness of the scraping and collection of the adhesive to be removed, the actual posture information can be characterized by at least one of multiple parameters. Optionally, the actual posture information may include the vertical distance between the adhesive collection component 200 and the web body 12a along the thickness direction Y, the tilt angle formed by the adhesive collection component 200 relative to the skin surface, and the contact pressure generated when the adhesive collection component 200 contacts and engages with the skin. These multi-dimensional parameters can comprehensively reflect the spatial position, angular posture, and contact state of the adhesive collection component 200 during operation, thereby reflecting the real-time relative engagement relationship between the adhesive collection component 200, the web 12, and the skin.

[0074] The target posture information is matched with preset vertical distance, preset tilt angle, and preset contact pressure under standard working conditions. At least one of these can be selected as the posture correction benchmark as needed. By comparing the actual posture information collected on site with the preset target posture information and calculating the difference, the working posture of the glue collection device 30 can be finely adjusted in real time according to the deviation, so that the glue collection part 200 always maintains a suitable working state. This can avoid incomplete glue removal caused by abnormal posture and prevent damage to the skin due to improper contact force.

[0075] See Figure 6 In some embodiments, the control component 300 includes a control element and a distance detection element 310 communicatively connected to the control element. The connector 100 includes a moving part 110 and a first adjustment part 120 connected to the moving part 110. The first adjustment part 120 has a degree of freedom of extension and retraction along a first direction and is capable of driving the adhesive retractor 200 to extend and retract. The adhesive retracting step includes: The control distance detection component 310 sequentially acquires the perpendicular distance between the adhesive receiving component 200 and the web body 12a along the thickness direction Y of the web body 12a. The control unit receives the vertical distance and determines the distance adjustment value based on the difference between the vertical distance and the preset vertical distance; The control unit controls the first adjustment part 120 to extend or shorten relative to the web body 12a in a first direction according to the distance adjustment value.

[0076] In other words, to achieve automated adjustment of the relative distance between the glue-collecting component 200 and the web body 12a, and to ensure the glue-collecting effect of the glue-cleaning operation, the control component 300 is equipped with a control component and a distance detection component 310. The distance detection component 310 maintains a communication connection with the control component, and can collect the vertical distance in real time and transmit it to the control component for analysis and processing. The connecting component 100 may include a moving part 110 and a first adjustment part 120. The first adjustment part 120 is fixedly connected to the moving part 110, and it has a degree of freedom of extension and retraction along the first direction. It can also simultaneously drive the glue-collecting component 200 to perform displacement adjustment in the same direction during the extension and retraction action.

[0077] During the glue collection process, the distance detection component 310 moves synchronously along the guide component 12b with the glue collection device 30, sequentially detecting and acquiring the vertical distance between the glue collection component 200 and the web body 12a along the thickness direction Y of the web body 12a in each target collection area. The control component receives the measured vertical distance transmitted by the distance detection component 310 in real time, compares it with the preset vertical distance, and accurately determines the corresponding distance adjustment value based on the deviation between the two. Subsequently, the control component outputs a control signal based on the distance adjustment value, driving the first adjustment unit 120 to adaptively extend or shorten relative to the web body 12a along the first direction to correct the relative position of the glue collection component 200, ensuring that the glue collection component 200 always maintains a reasonable working distance and ensuring a uniform and stable scraping effect of the overflow glue. Here, the first direction can be understood as the thickness direction Y of the web body 12a.

[0078] Optionally, the distance detection element 310 may include at least one of a laser rangefinder, an ultrasonic rangefinder, and an infrared distance sensor.

[0079] Optionally, the preset vertical distance can be any value between 30mm and 40mm, including the two end values ​​of 30mm and 40mm. Specifically, it can be set according to the model and specifications of the web plate 12 and the shell 11. This embodiment of the application does not impose any limitations on it.

[0080] See Figure 6In some embodiments, the control component 300 includes a control element and a pressure detection element 320 communicatively connected to the control element. The connector 100 further includes a second adjustment portion 130, which is connected to one end of the first adjustment portion 120 away from the moving portion 110 and has a degree of freedom of extension and retraction in a second direction. The adhesive collection component 200 is connected to the second adjustment portion 130, and the adhesive collection step includes: The control pressure detection component 320 sequentially acquires the contact pressure between the adhesive receiving component 200 and the skin; The control unit receives the contact pressure and determines the pressure adjustment value based on the difference between the contact pressure and the preset contact pressure. The control unit controls the second adjustment section 130 to extend or shorten relative to the skin in the second direction according to the pressure adjustment value; The preset contact pressure is N, where 0.1MPa≤N≤0.3MPa.

[0081] It should be noted that, in order to accurately control the contact pressure between the take-up component 200 and the skin, and to avoid excessive contact pressure damaging the skin surface or insufficient contact pressure leading to incomplete take-up, the control component 300 may also include a pressure detection component 320 that is communicatively connected to the control component. The pressure detection component 320 can collect the contact pressure between the take-up component 200 and the skin in real time and transmit it to the control component. The connector 100 may also be provided with a second adjustment part 130, which is fixedly connected to the end of the first adjustment part 120 away from the moving part 110. The second adjustment part 130 itself has a degree of freedom of extension and retraction in the second direction. The take-up component 200 can be assembled at the end of the second adjustment part 130 away from the first adjustment part 120, and the position of the take-up component 200 can be adjusted in the second direction with the extension and retraction of the second adjustment part 130.

[0082] During the glue collection step, the pressure detection element 320 moves synchronously along the guide 12b with the glue collection device 30, sequentially collecting and acquiring the contact pressure generated when the glue collection element 200 contacts the skin surface in each target collection area. The control unit receives the actual contact pressure transmitted by the pressure detection element 320 in real time, compares and analyzes it with the preset contact pressure, and accurately determines the corresponding pressure adjustment value based on the deviation between the two. Subsequently, the control unit outputs a corresponding control signal based on the pressure adjustment value, driving the second adjustment part 130 to adaptively extend or shorten relative to the skin in the second direction, thereby adjusting the contact pressure between the glue collection element 200 and the skin, ensuring that it always conforms to the preset contact pressure requirement. This ensures that the glue collection element 200 can effectively scrape off the overflow glue while avoiding damage to the skin, thus guaranteeing operational stability and blade surface integrity. Here, the second direction can be understood as the height direction X of the web body 12a.

[0083] Optionally, the pressure sensing element 320 may include at least one of a thin-film pressure sensor, a piezoelectric pressure sensor, or a strain gauge pressure sensing module.

[0084] See Figure 6 In some embodiments, the control component 300 includes a control element and a tilt detection element 330 communicatively connected to the control element. The adhesive collection element 200 is rotatably connected to the connector 100 and has a rotational degree of freedom about a third direction. The adhesive collection step includes: The tilt angle detection component 330 sequentially acquires the tilt angle between the glue collection component 200 and the skin; The control unit receives the tilt angle and determines the tilt angle adjustment value based on the difference between the tilt angle and the preset tilt angle; The control component controls the rotation of the take-up part 200 relative to the skin in a third direction based on the tilt angle adjustment value.

[0085] Understandably, in order to precisely adjust the relative tilt angle between the adhesive take-up component 200 and the skin, ensuring that the adhesive take-up component 200 conforms to the contour of the skin surface and achieves complete removal of the adhesive to be removed, while avoiding adhesive residue or skin damage caused by tilt angle deviation, the control component 300 may also include a tilt angle detection component 330 that is communicatively connected to the control component. The tilt angle detection component 330 can collect the tilt angle data between the adhesive take-up component 200 and the skin in real time and transmit the collected signal to the control component for analysis and processing. The adhesive take-up component 200 and the connecting component 100 adopt a rotatable connection assembly method, which gives the adhesive take-up component 200 a degree of rotational freedom around a third direction. It can flexibly adjust its tilt angle with the skin according to actual operation requirements to adapt to the contour shape of different areas of the skin.

[0086] In practice, the tilt angle detection component 330 moves smoothly along the guide 12b along with the glue collection device 30. As it passes through each target collection area, it detects and acquires the actual tilt angle between the glue collection component 200 and the skin surface in real time. The control unit receives the measured tilt angle transmitted by the tilt angle detection component 330 in real time, compares it with a preset tilt angle, and calculates the corresponding tilt angle adjustment value based on the deviation between the two. Subsequently, the control unit outputs corresponding control commands based on the tilt angle adjustment value, driving the glue collection component 200 to adaptively rotate relative to the skin around a third direction. This ensures that the glue collection component 200 is always properly fitted to the skin surface, guaranteeing the uniformity and thoroughness of the glue scraping effect, while protecting the skin surface from damage. Here, the third direction can be understood as the length direction of the web body 12a.

[0087] Optionally, the tilt detection element 330 may include at least one of a tilt sensor, a gyroscope, an attitude sensor, and an angle encoder.

[0088] In some optional embodiments, the tilt angle and contact pressure of the adhesive collection component 200 can be coordinated and controlled. During actual control, a working logic can be set to prioritize calibrating the tilt angle and then calibrating the contact pressure. That is, the adhesive collection component 200 is first adjusted to a fitting tilt angle that matches the curvature of the skin surface via the control components. Then, under this reference posture, the contact pressure between the adhesive collection component 200 and the skin is corrected using the pressure detection component 320. The preset tilt angle and preset contact pressure can be pre-calibrated and dynamically adaptively assigned based on actual working conditions such as the viscosity of the adhesive to be removed, the thickness of the buildup, and the local curvature of the skin surface. Differential adaptation parameters are provided for different adhesive states: when the viscosity of the adhesive to be removed is high and the buildup layer is thick, the preset contact pressure can be appropriately increased. This ensures that adhesive of different properties can be completely scraped and collected, while avoiding hard scraping damage to the skin surface and bonding interface.

[0089] Based on the above embodiments, this application provides a wind turbine blade 10, including a shell 11 and a web 12. The shell 11 has a cavity 11a and includes a skin that surrounds the cavity 11a. The web 12 is located within the cavity 11a and connected to the skin.

The first end and the second end are provided with flanges 121a. The guide member 12b is connected to the web body 12a and located between the first end and the second end. The guide member 12b extends along the length direction of the web body 12a.

[0090] The shell 11 has a cavity 11a inside to accommodate various components. The skins of the shell 11 surround each other, forming the outer contour of the wind turbine blade 10, providing installation and protection space for the components inside the cavity 11a. The web 12 is located inside the cavity 11a of the shell 11 and is an important load-bearing structure of the wind turbine blade 10. It may include an integrally formed web body 12a. The web body 12a has a first end and a second end arranged opposite each other along its height direction X. Both ends are provided with flanges 121a, which are used to fix and connect with the skin to ensure the connection is firm. A guide member 12b is also connected to the web body 12a. The guide member 12b is located between the first end and the second end and extends along the length direction of the web body 12a. One end of the guide member is fixedly connected to the web body 12a, which can provide a stable moving guide base for the glue removal operation, ensuring the smooth progress of the glue removal operation, and thus ensuring the stability and safety of the overall structure of the wind turbine blade 10.

[0091] Optionally, the web plate 12 can be configured as one or more.

[0092] See Figure 6Based on the above embodiments, this application provides a glue collection device 30 for a wind turbine blade 10, applied to the above-described glue collection method for the wind turbine blade 10, including a connector 100, a glue collection component 200, and a control component 300. The connector 100 is detachably connected to the web 12 of the wind turbine blade 10, and the connector 100 is provided with a moving part 110. The glue collection component 200 is connected to the connector 100, and includes a scraping part 210 and a collecting part 220. The scraping part 210 is used to scrape off the extruded glue and collect the extruded glue in the collecting part 220. The control component 300 is connected to the connector 100, and the control component 300 is used to acquire the actual posture information of the glue collection device 30, and adjust the working posture of the glue collection device 30 relative to the flange 121a and the skin according to the difference between the actual posture information and the target posture information.

[0093] The connector 100 is used to detachably connect to the web 12 of the wind turbine blade 10, facilitating the installation, disassembly, and subsequent recycling and reuse of the glue collection device 30. Its movable part 110 can drive the entire glue collection device 30 smoothly along the guide 12b on the web 12, providing stable mobile support for the glue collection operation. Optionally, the driving method of the movable part 110 can be flexibly selected, such as: PLC automatic walking drive, spring energy storage traction, wire rope manual traction, pneumatic propulsion, motor-built-in trolley, etc. Correspondingly, the movable part 110 may include at least one of the following: spring energy storage traction mechanism, wire rope manual traction assembly, pneumatic propulsion mechanism, and motor-built-in walking trolley.

[0094] The adhesive collection component 200 is fixedly connected to the connector 100. The adhesive collection component 200 may include an adhesive scraping part 210 and a collection part 220. The adhesive scraping part 210 can conform to the bonding area between the skin and the flange 121a, efficiently scraping away excess adhesive squeezed out during bonding, while smoothly guiding the scraped adhesive into the collection part 220 for centralized collection, preventing adhesive from scattering and contaminating the blade surface or causing material waste. Optionally, the adhesive scraping part 210 may include at least one of a rigid scraper, a rubber scraper, a multi-layer composite scraper head, an adaptive floating scraper, a rotating scraper wheel, an airbag-pressurized scraper head, or an adjustable angle scraper. The collection part 220 may include at least one of a collection tank, a removable adhesive bag, absorbent cotton, a spiral adhesive guide tube, or a disposable adhesive collection box. The collection section 220 can be correspondingly arranged downstream of the scraping section 210 in the scraping direction, and the inlet of the collection section 220 is arranged facing the flange 121a of the web body 12a. In specific implementation, the scraping section 210 completes the scraping of the adhesive by adhering to the working surface. Due to the pushing force generated by the scraping section 210 when it scrapes and the lateral limiting and guiding effect of the flange 121a, the adhesive to be removed can enter the inlet of the collection section 220 along the guide path formed by the side wall of the scraping section 210 and the flange 121a. The collection section 220 receives and guides the waste adhesive, realizing the scraping and adhesive collection functions.

[0095] The control component 300 is securely connected to the connector 100, and can collect the actual posture information of the glue collection device 30 in real time. It can compare and analyze the actual posture information with the preset target posture information, and accurately adjust the working posture of the glue collection device 30 relative to the flange 121a and the skin according to the deviation value between the two, so as to ensure that the glue is scraped thoroughly and the force is even, while protecting the skin surface.

[0096] In some embodiments, the control component 300 includes a control element, a distance detection element 310, a pressure detection element 320, and a tilt detection element 330, which are communicatively connected to the control element.

[0098] Optionally, the pressure detection element 320 can be located at the end of the take-up part 200 that contacts the skin.

[0099] The adhesive collection method and adhesive collection device 30 for wind turbine blades 10 provided in this application embodiment can be applied not only to the bonding of the web 12 and the shell 11, but also to various mainstream molding processes of wind turbine blades 10 such as co-curing, co-bonding, and secondary injection. It can meet the adhesive overflow cleaning needs under different manufacturing processes, and this application embodiment does not limit it. Among them, co-curing refers to the integrated molding process in which the wind turbine blade 10 skin, web 12 and other components are pre-aligned and bonded, and then the resin matrix is ​​simultaneously injected and the whole is heated and cured, so that each component completes molding and interface bonding at one time. Co-bonding refers to the overall bonding molding process in which structural adhesive is simultaneously applied to the interface of multiple components and aligned and pressed during the blade assembly stage, without the need for step-by-step bonding. Secondary injection refers to the step-by-step injection molding process in which resin or structural adhesive is injected into the blade cavity 11a and the gap between components in two stages according to the process sequence, and the gap filling, interface wetting and curing bonding are completed in steps, which is suitable for complex cavity and large gap assembly.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
