[0043] Wind turbine blades are key components of wind turbine generators. After they are ejected from the mold and rolled off the production line, the first post-processing step is to remove the flash from both the leading and trailing edges. As wind turbine blades are currently being manufactured in larger and longer sizes, with mainstream blades typically exceeding 100 meters in length, the flash on both sides, which are ejected from the mold and rolled off the production line together, also exceed 100 meters in length.

[0044] However, currently, wind turbine blade flash is usually cut and removed manually using a cornea cutter, which results in heavy workload, high safety risks, low cutting efficiency, and unstable cutting quality. Moreover, blade flash cutting generates a large amount of dust, which scatters and pollutes the environment and harms human health.

[0045] Based on this, the utility model proposes a wind turbine blade flash cutting device, which realizes automatic cutting of flash, can reduce workload, improve safety factor, cutting efficiency and cutting quality, and can also effectively prevent dust from scattering. Figure 1 This is a structural schematic diagram of an embodiment of a wind turbine blade flash cutting device provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of the cutting mechanism at one angle; Figure 3 for Figure 2 Schematic diagram of the structure from another angle; Figure 4 for Figure 2 Schematic diagram of the structure from another angle.

[0046] See also Figure 1 and Figure 2 In one embodiment of the present invention, a wind turbine blade flash cutting device 1000 includes an automatic guided vehicle 100, a truss 200, a cutting mechanism 300 and a dust suction mechanism 400, wherein the truss 200 is arranged on the automatic guided vehicle 100; the cutting mechanism 300 is arranged on the truss 200 and can move in the up and down directions, the cutting mechanism 300 includes a first cutting head 2 for cutting the blade flash 500 along the longitudinal direction; the dust suction mechanism 400 is arranged on the automatic guided vehicle 100, and the dust suction mechanism 400 includes a first dust suction port 410, which is arranged corresponding to the first cutting head 2 to collect dust from cutting the blade flash 500.

[0047] The technical solution of the present invention is to set the cutting mechanism 300 on the automatic guided vehicle 100 (AGV) by using a truss 200. The automatic guided vehicle 100 is pulled and automatically navigated. The cutting mechanism 300 can be moved in the up and down directions on the truss 200 to adjust the height of the first cutting head 2. During the movement of the automatic guided vehicle 100, the first cutting head 2 can cut the blade flash 500 along the longitudinal direction (the length direction of the wind turbine blade), thereby realizing automatic cutting of the flash, reducing workload, and improving safety factor, cutting efficiency and cutting quality; and a dust suction mechanism 400 is set on the automatic guided vehicle 100. During the process of the first cutting head 2 cutting the blade flash 500, the dust suction mechanism 400 can collect dust through the first dust suction port 410, effectively preventing dust from scattering.

[0048] It can be understood that the dust suction mechanism 400 includes a dust removal system, and the first dust suction port 410 is connected to the dust removal system through a pipeline.

[0049] In an embodiment of the present invention, the cutting mechanism 300 further comprises a mounting frame 1, comprising a top plate 11 and a back plate 12. The top plate 11 is vertically slidably connected to the truss 200. The back plate 12 is disposed below the top plate 11. The first cutting head 2 is rotatably mounted on the back plate 12. The back plate 12 is laterally movable to adjust the cutting position of the first cutting head 2. The height of the first cutting head 2 can be adjusted via the top plate 11, and the position of the first cutting head 2 in the transverse direction (across the width of the wind turbine blade) can be adjusted via the back plate 12, thereby improving the cutting quality of the blade flash 500. It is understood that the truss 200 comprises a pair of vertical bars, with the top plate 11 positioned between the pair of vertical bars and vertically slidably connected to each of the pair of vertical bars. The sliding connection can be achieved by providing a vertically extending slide rail on each opposing surface of the pair of vertical bars, with sliders disposed on either side of the top plate 11 for engaging with the slide rails. The top plate 11 is moved vertically by a linear drive assembly.

[0050] In an embodiment of the present invention, the first cutting head 2 is rotatably connected to the back plate 12 via a telescopic electric spindle 21. Mounting the first cutting head 2 on the back plate 12 via the telescopic electric spindle 21 not only facilitates opening and closing of the first cutting head 2 but also allows for fine-tuning of the lateral position of the first cutting head 2, thereby improving the efficiency and quality of cutting the blade flash 500.

[0051] In an embodiment of the present invention, the cutting mechanism 300 further includes two guide wheel assemblies, which are arranged on the back plate 12 at intervals in the vertical direction and are used to move along the groove of the blade flash 500. By embedding the two guide wheel assemblies in the groove of the blade flash 500, not only can the blade flash 500 be stabilized, but the first cutting head 2 can also be guided to advance along the profile of the blade flash 500, so that the cross-section is closely attached to the wind turbine blade body, thereby improving the cutting quality of the blade flash 500. It is understandable that, from the perspective of the travel direction of the automatic guided vehicle 100, the two guide wheel assemblies are located in front of the first cutting head 2. It is understandable that the guide wheel assemblies can be unpowered wheel assemblies or self-powered wheel assemblies.

[0052] In the embodiments of the present invention, please refer to Figure 3 The cutting mechanism 300 further includes a guide groove 4 disposed on the back plate 12 and located between the two guide wheel assemblies for guiding the blade flash 500. The guide groove 4 can guide the portion of the blade flash 500 to be cut ahead of the AGV 100, thereby improving the cutting quality of the blade flash 500.

[0053] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 Each guide wheel assembly includes at least two guide wheels 3 arranged along the longitudinal direction. Each guide wheel assembly includes multiple guide wheels 3, which helps improve the stability of the guide wheel assembly during operation. The number of guide wheels 3 in each guide wheel assembly can be two, which simplifies the structure and improves operation stability while also facilitating adaptation to the contours of the blade flash 500. The width of each guide wheel 3 can be selected to be the same as the groove of the blade flash 500, which helps improve the stability of the guide wheel 3 during operation.

[0054] In the embodiment of the present invention, each guide wheel 3 is movable in the vertical direction to adjust the height of the guide wheel 3. By moving the guide wheel 3 in the vertical direction, a certain degree of height compensation can be achieved to accommodate the height variation of the blade flash 500. It is understood that each guide wheel 3 can be connected to the back plate 12 via a linear drive assembly to achieve vertical movement of the guide wheel 3. The linear drive assembly of the guide wheel 3 can be a pneumatic cylinder 31, which has a simple structure and is easy to control.

[0055] In an embodiment of the present invention, the cutting mechanism 300 further includes a height detection assembly 5, which is disposed on the back plate 12 and is configured to detect height changes in the groove of the blade flash 500. The height detection assembly 5 can detect height changes in the groove of the blade flash 500, and the height of the first cutting head 2 can be adjusted accordingly, thereby improving the efficiency and quality of cutting the blade flash 500. It is understood that the height detection assembly 5 can be a height detection sensor or a contact or non-contact distance-measuring device such as a ranging laser. There can be one or more height detection assemblies 5. Furthermore, the cutting mechanism 300 includes two guide wheel assemblies, each of which includes at least two guide wheels 3 arranged longitudinally. Each guide wheel 3 is movable in the vertical direction. Based on the height changes in the groove of the blade flash 500 detected by the height detection assembly 5, the guide wheels 3 can be selectively moved in the vertical direction for height compensation.

[0056] In the embodiments of the present invention, please refer to Figure 4 The mounting frame 1 further includes a connecting frame 13, which is disposed between the top plate 11 and the back plate 12. The upper end of the connecting frame 13 is slidably connected to the top plate 11 in the transverse direction, and the back plate 12 is rotatably connected to the connecting frame 13. The connecting frame 13 enables both lateral sliding and rotatable connection between the back plate 12 and the top plate 11. This not only allows the position of the first cutting head 2 to be adjusted in the transverse direction, but also allows the back plate 12 to swing along with the movement of the pair of guide wheels, driving the first cutting head 2 to swing along with the movement to adapt to the curvature change of the groove of the blade flash 500, thereby improving the cutting efficiency and quality of the blade flash 500.

[0057] In an embodiment of the present invention, the connecting frame 13 includes a pair of transverse plates and a pair of vertical plates. The transverse plates are spaced apart in the vertical direction, and the vertical plates are spaced apart in the longitudinal direction between the transverse plates. The transverse plates are sequentially connected to the vertical plates, and the upper transverse plate is slidably connected to the top plate 11 in the horizontal direction. A rotating shaft 14 extending in the vertical direction is disposed within the connecting frame 13, and the two ends of the rotating shaft 14 are rotatably connected to the pair of transverse plates. The rotating shaft 14 is connected to the back plate 12. The connecting frame 13 has a simple structure. The rotating shaft 14 disposed within the connecting frame 13 and the back plate 12 are rotatably connected, allowing the back plate 12 to swing smoothly and stably, thereby improving the efficiency and quality of cutting the blade flash 500. It is understood that two horizontally extending slide rails can be disposed on the bottom surface of the top plate 11, and a slider that cooperates with the slide rails can be disposed on the top surface of the upper transverse plate. The connecting frame 13 achieves lateral movement via a linear drive assembly.

[0058] In an embodiment of the present invention, the connecting frame 13 is equipped with an angle detection assembly 6 for detecting changes in the rotation angle of the backplate 12. The angle detection assembly 6 detects changes in the rotation angle of the backplate 12, reflecting changes in the curvature of the groove of the blade flash 500. This information is then fed back to the AGV 100, allowing the AGV 100 to navigate along the curvature profile of the blade flash 500 and maintain a stable distance from the blade flash 500. It is understood that the angle detection assembly 6 can be a wire encoder or other device capable of detecting a deflection angle.

[0059] In the embodiments of the present invention, please refer to Figure 2 The cutting mechanism 300 further includes a second cutting head 7 and a mounting seat. The second cutting head 7 is rotatably mounted on the mounting seat. The mounting seat is disposed on the mounting frame 1 and is movable in the transverse direction. The second cutting head 7 is used to cut the blade flash 500 in the transverse direction. The second cutting head 7 enables transverse cutting of the blade flash 500. After the blade flash 500 is cut to a predetermined length in the longitudinal direction, the second cutting head 7 is used to cut the blade flash 500 transversely. This effectively reduces the impact of the cut flash on the cutting of the first cutting head 2, thereby further improving the cutting quality of the blade flash 500. It will be understood that, from the perspective of the automatic guided vehicle 100's travel direction, the second cutting head 7 is located behind the first cutting head 2.

[0060] In an embodiment of the present invention, the mounting frame 1 further includes a connecting frame 13, within which is disposed a vertically extending shaft 14; the mounting seat is slidably connected to the shaft 14 along the transverse direction. The mounting seat of the second cutting head 7 is mounted on the shaft 14, allowing the second cutting head 7 to swing with the backing plate 12, further improving the efficiency and quality of cutting the blade flash 500. It is understood that a slide rail extending laterally may be disposed on the shaft 14, and the mounting seat may be provided with a slider that cooperates with the slide rail; the mounting seat achieves lateral movement via a linear drive assembly.

[0061] In an embodiment of the present invention, the second cutting head 7 is rotatably connected to the mounting base via an electric spindle 71. The second cutting head 7 is mounted on the mounting base via the electric spindle 71, which facilitates the control of the opening and closing of the second cutting head 7.

[0062] In this embodiment of the present invention, the dust collection mechanism 400 further includes a second dust collection port 420, which is provided in correspondence with the second cutting head 7 and is used to collect dust from the blade flash 500. During the process of the second cutting head 7 transversely severing the blade flash 500, the dust collection mechanism 400 can collect dust through the second dust collection port 420, further preventing dust from dispersing. It is understood that the second dust collection port 420 can be connected to the dust removal system of the dust collection mechanism 400 via a duct.

[0063] In an embodiment of the present invention, the cutting mechanism 300 further includes a baffle 8, which is disposed on the backplate 12 and corresponds to the second cutting head 7. The baffle 8 serves to limit the lateral movement of the second cutting head 7. By providing the baffle 8 to limit the lateral movement of the second cutting head 7, it is possible to effectively prevent the second cutting head 7 from damaging the wind turbine blade body. It will be appreciated that during the cutting process, the baffle 8 is positioned between the cut burr and the blade body, and along the lateral movement path of the second cutting head 7, thereby providing a limiting position.

[0064] The present invention also proposes a wind turbine blade flash cutting control method, which uses the above-mentioned wind turbine blade flash cutting device 1000. The specific structure of the wind turbine blade flash cutting device 1000 refers to the above-mentioned embodiment. Since the present wind turbine blade flash cutting control method adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Among them, the cutting mechanism 300 also includes a mounting frame 1 and two guide wheel groups. The mounting frame 1 includes a top plate 11 and a back plate 12. Each of the guide wheel groups includes at least two guide wheels 3 arranged in the longitudinal direction, and each of the guide wheels 3 can move in the up and down directions.

[0065] The wind turbine blade flash cutting control method comprises the following steps:

[0066] Obtaining a height change value of the groove of the blade flash 500;

[0067] When the height change value satisfies the first height adjustment condition, the first linear drive assembly is controlled to drive the guide wheel 3 to move, so as to adjust the position of the guide wheel 3 relative to the back plate 12 in the vertical direction;

[0068] When the height change value satisfies a second height adjustment condition, the second linear drive assembly is controlled to drive the top plate 11 to move, so as to adjust the position of the top plate 11 relative to the truss 200 in the vertical direction.

[0069] By adjusting the height of the guide wheel 3 and the top plate 11, it is possible to adapt to the height variation of the groove of the wind turbine blade flash 500 (groove height variation of 0.3m to 4m), covering all current height conditions of the wind turbine blade flash 500. It is understandable that the height variation value can be the difference between the currently detected height and the starting height. The first height adjustment condition is that the height variation value is less than or equal to the vertical movement stroke of the guide wheel 3. The second height adjustment condition is that the height variation value is greater than the vertical movement stroke of the guide wheel 3. The first linear drive assembly is a linear drive assembly that drives the guide wheel 3 to move in the vertical direction, and the second linear drive assembly is a linear drive assembly that drives the top plate 11 to move in the vertical direction along the truss 200.

[0070] In an embodiment of the present invention, the cutting mechanism 300 further includes a second cutting head 7, which is movable in the transverse direction. The wind turbine blade flash cutting control method further includes the following steps:

[0071] Obtaining the travel distance of the automatic guided vehicle 100;

[0072] When the travel distance meets the preset cross-cutting condition, the automatic guided vehicle 100 is controlled to stop, the first cutting head 2 is closed, the second cutting head 7 is controlled to cut the blade flash 500 in the transverse direction, and the second cutting head 7 is controlled to return.

[0073] When the AGV's 100 travel distance satisfies a preset transverse cutting condition, the second cutting head 7 is controlled to transversely cut the blade flash 500, thereby improving the efficiency and quality of cutting the blade flash 500. It will be appreciated that the AGV's 100 travel distance can be recorded by an encoder, and the travel distance can be calculated from the point where the AGV 100 begins cutting the wind turbine blade flash 500. The transverse cutting condition is that the travel distance is an integer multiple of a preset threshold, which can be 2 meters. This means that after the first cutting head 2 cuts 2 meters of blade flash 500 longitudinally, it performs a transverse cut. It can be understood that when the automatic guided vehicle 100 moves along the length direction of the blade, the second cutting head 7 is in its original position (that is, it moves laterally to the extreme position away from the blade and does not interfere with the blade flash 500), the first cutting head 2 is turned on, and the blade flash 500 is cut longitudinally; the specific operation of controlling the second cutting head 7 to cut the blade flash 500 laterally is to control the second cutting head 7 to move laterally toward the direction close to the blade, and after cutting off the blade flash 500 (reaching the preset movement displacement), the second cutting head 7 is closed and moved laterally to its original position.

[0074] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
