Description

Technical Field

[0001] This disclosure relates to the technical field of auxiliary equipment for blade production, and particularly to an auxiliary material removal device. Background Technology

[0002] In the field of wind turbine blade manufacturing, after the blade is cast, auxiliary materials such as vacuum film and air guide net need to be removed from the surface. Currently, this step mostly relies on manual removal. However, manual operation is inefficient, and workers must tear off the auxiliary materials one by one, slowly and carefully, which consumes a lot of manpower and time. Utility Model Content

[0003] The purpose of this disclosure is to provide an auxiliary material removal device that can automatically remove auxiliary materials and improve production efficiency.

[0004] According to one aspect of this disclosure, an auxiliary material removal device is provided for removing auxiliary materials from a workpiece. The auxiliary material removal device includes a moving device, a take-up shaft, and a first driving component, wherein the moving device moves at least along the length direction of the auxiliary material; the take-up shaft is disposed on the moving device and extends at least partially directly above the auxiliary material; the first driving component is disposed on the moving device and is used to drive the take-up shaft to rotate so as to take up the auxiliary material by the rotation of the take-up shaft.

[0005] The technical solution provided in this disclosure uses a moving device to drive a take-up shaft along the length of the auxiliary material, and removes the auxiliary material through the rotation of the take-up shaft. Compared to removing the auxiliary material along its width, this disclosure allows the removal force applied by the take-up shaft to be distributed relatively evenly across the entire width of the auxiliary material, reducing local stress concentration and making the removal process smoother. It also reduces the amount of broken auxiliary material remaining on the workpiece surface, improving removal efficiency. Furthermore, since the take-up shaft extends at least partially above the auxiliary material, the removal force applied by the take-up shaft can be further evenly distributed across the entire width of the auxiliary material, reducing local stress concentration. Especially for removing auxiliary materials after wind turbine blade injection, where the aspect ratio of the auxiliary materials used for injection is extremely large, continuously winding and removing the auxiliary material along its length not only avoids breakage but also reduces the winding force required by the take-up shaft, thereby reducing the overall cost of the auxiliary material removal equipment.

[0006] Meanwhile, by using a rewinding shaft to remove auxiliary materials, the materials can be rolled up and stored, preventing them from scattering during the removal process and optimizing the removal operation.

[0007] Optionally, the auxiliary material removal device further includes a counterweight and a second driving component; the two ends of the take-up shaft extend to opposite sides of the moving device, one end of the take-up shaft is used to take up the auxiliary material, and the other end of the take-up shaft is slidably connected to the counterweight; the second driving component is disposed on the moving device and is used to drive the counterweight to move along the axis of the take-up shaft.

[0008] The above scheme uses a second driving component to drive the counterweight to move along the axis of the winding shaft, thereby adjusting the distance between the counterweight and the moving device to balance the center of gravity of the moving device, prevent the moving device from tilting, and ensure the stable operation of the auxiliary material removal equipment.

[0009] Optionally, the mobile device is provided with a first sensor and a second sensor, which are configured to detect the pressure of the take-up shaft on two preset points distributed along the axis of the take-up shaft on the mobile device.

[0010] The above scheme allows for precise adjustment of the counterweight by controlling the movement length of the second drive component based on the pressure at two preset points, thereby ensuring the stable operation of the auxiliary material removal equipment.

[0011] Optionally, the moving device includes a moving body and a lifting component, wherein the moving body is connected to the take-up shaft via the lifting component.

[0012] The above solution allows for the control of the winding shaft height via a lifting mechanism, making it suitable for removing auxiliary materials from workpieces of different heights.

[0013] Optionally, the moving device further includes a rotating component, and the moving body is connected to the lifting component via the rotating component, or the lifting component is connected to the take-up shaft via the rotating component.

[0014] With the above solution, when the take-up shaft has wound up enough weight, or when the auxiliary material has been wound up, the rotating component can drive the take-up shaft to rotate and detach from directly above the workpiece, so as to facilitate unloading.

[0015] Optionally, the auxiliary material removal device further includes a pushing component and a third driving component, wherein the third driving component is disposed on the moving device, and the third driving component drives the pushing component to move along the axis of the take-up shaft to push the auxiliary material to be taken up by the take-up shaft out of the take-up shaft.

[0016] Through the above solution, the third drive component drives the pushing component to move along the axis of the take-up shaft, thereby pushing the auxiliary material wound on the take-up shaft off the take-up shaft, eliminating the need for manual unloading and improving efficiency.

[0017] Optionally, the pushing component includes a pusher plate, and the third driving component is connected to the pusher plate.

[0018] Optionally, the pushing component further includes at least one first cutting blade connected to the pushing plate, wherein the first cutting blade is located in front of the pushing plate along the extension direction of the pushing component.

[0019] With the above scheme, when the third driving component drives the pushing component to extend, the first cutting blade can first cut the rolled auxiliary material on the take-up shaft, and at the same time the push plate pushes out the auxiliary material that has been cut into strips and is still attached to the take-up shaft, thereby avoiding the situation where the friction between the rolled auxiliary material and the take-up shaft is too great and cannot be pushed out, which facilitates the unloading operation.

[0020] Optionally, the pusher plate is at least partially arranged around the take-up shaft; the first cutter has a plurality of blades, which are spaced apart around the axis of the take-up shaft.

[0021] Optionally, the auxiliary material removal device further includes a second cutting blade and a fourth driving component, wherein the fourth driving component is disposed on the moving device and connected to the second cutting blade, and the fourth driving component drives the second cutting blade to move along the axis of the take-up shaft.

[0022] With the above solution, when the auxiliary material wound by the winding shaft reaches the weight that the counterweight structure can balance or the preset weight, the fourth driving component can first drive the second cutting blade to extend and cut and separate the connection between the wound auxiliary material and the unwound auxiliary material, thus eliminating the need for manual cutting and improving the efficiency of auxiliary material removal.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this disclosure, but not all embodiments.

[0039] like Figures 1 to 3 As shown, this disclosure provides an auxiliary material removal device for removing auxiliary materials 20 from a workpiece 10. For example, the workpiece 10 may be a blade half-shell, and the auxiliary material 20 may be a sheet such as a vacuum film or a flow guide net laid on the inner wall of the blade half-shell. Alternatively, the workpiece 10 may be a mold for producing the blade half-shell, and the auxiliary material 20 may be a sheet such as a vacuum film or a flow guide net laid on the inner wall of the mold.

[0040] Specifically, the auxiliary material removal device may include a moving device 100, a take-up shaft 210, and a first drive component 220, wherein the moving device 100 moves at least along the length direction of the auxiliary material 20. The take-up shaft 210 is disposed on the moving device 100, and at least a portion of the take-up shaft 210 extends directly above the auxiliary material 20. The first drive component 220 is disposed on the moving device 100 and is used to drive the take-up shaft 210 to rotate, so as to take up the auxiliary material 20 by the rotation of the take-up shaft 210.

[0041] For example, the mobile device 100 may have a self-moving function, that is, the mobile device 100 has an integrated drive structure. Of course, the mobile device 100 may also rely on an external drive structure to drive its movement. The first drive component 220 may be a motor.

[0042] It is worth mentioning that the moving device 100 drives the take-up shaft 210 to move along the length direction of the auxiliary material 20, and the rotation of the take-up shaft 210 removes the auxiliary material 20. Thus, compared to removing the auxiliary material 20 along its width, this disclosure allows the removal force applied by the take-up shaft 210 to the auxiliary material 20 to be distributed relatively evenly across the entire width of the auxiliary material 20, reducing local stress concentration and making the removal process smoother. It also reduces the amount of the auxiliary material 20 remaining on the surface of the workpiece 10 after breakage, improving removal efficiency. Furthermore, since the take-up shaft 210 extends at least partially above the auxiliary material 20, the removal force applied by the take-up shaft 210 to the auxiliary material 20 can be further distributed relatively evenly across the entire width of the auxiliary material 20, reducing local stress concentration. Especially for the removal of auxiliary material 20 after the wind turbine blade is injected, the length-to-width ratio of the auxiliary material 20 used for wind turbine blade injection is extremely large. By continuously winding and removing the auxiliary material 20 along its length, not only can the auxiliary material 20 be prevented from breaking, but the winding force requirement of the winding shaft 210 can also be reduced, thereby reducing the cost of the entire auxiliary material removal equipment.

[0043] At the same time, by winding the auxiliary material 20 away with the take-up shaft 210, the auxiliary material 20 can also be rolled up and stored, avoiding the auxiliary material 20 from being scattered during the removal process and optimizing the removal operation.

[0044] Furthermore, the take-up shaft 210 spans across the workpiece 10 along the width direction of the workpiece 10, thereby allowing the removal force applied by the take-up shaft 210 to the auxiliary material 20 to be distributed relatively evenly across the entire width of the auxiliary material 20, reducing local stress concentration.

[0045] In some embodiments, the moving device 100 may move only along the length direction of the auxiliary material 20, thus the moving device 100 can move in a single direction, thereby simplifying the design process and reducing design costs.

[0046] Considering that the edge of the blade half-shell is a curved shape, or that the edges of the workpiece 10 and the auxiliary material 20 may be curved, in order for the winding shaft 210 to completely wind up the auxiliary material 20, in some other embodiments, the moving device 100 can move along the edge of the auxiliary material 20. In this case, the moving device 100 moves not only along the length direction of the auxiliary material 20, but also has a certain movement component in the width direction of the auxiliary material 20.

[0047] In some embodiments, the auxiliary material removal device also has a counterweight structure, which is disposed on the moving device 100 to balance the center of gravity of the moving device 100 and prevent the moving device 100 from tilting.

[0048] Specifically, such as Figure 2 and Figure 4 As shown, the two ends of the take-up shaft 210 extend to opposite sides of the moving device 100. One end of the take-up shaft 210 extends directly above the auxiliary material 20 and is used to take up the auxiliary material 20. The other end of the take-up shaft 210 is slidably connected to a counterweight 310. A second drive component 320 is provided on the moving device 100. The second drive component 320 is used to drive the counterweight 310 to move along the axis of the take-up shaft 210, thereby adjusting the distance between the counterweight 310 and the moving device 100 to balance the center of gravity of the moving device 100.

[0049] For example, the counterweight 310 is movably connected to the second drive component 320, so that the second drive component 320 does not bear the vertical weight of the counterweight 310, but only drives the counterweight 310 to move along the axis of the take-up shaft 210. The sliding of the counterweight 310 on the take-up shaft 210 does not affect the rotation operation of the take-up shaft 210 relative to the counterweight 310. The second drive component 320 can be an electric cylinder or a pneumatic cylinder, or it can be composed of a motor, a transmission mechanism, and a lead screw mechanism.

[0050] In some embodiments, the second drive component 320 controls the movement length of the counterweight 310 based on the number of rotations of the take-up shaft 210.

[0051] Of course, in some other embodiments, such as Figure 2 and Figure 4 As shown, the mobile device 100 is provided with a first sensor 410 and a second sensor 420. The first sensor 410 and the second sensor 420 are configured to detect the pressure of the take-up shaft 210 on two preset points distributed along the axis of the take-up shaft 210 on the mobile device 100. Based on the magnitude of the pressure detected at the two preset points, the second drive component 320 can be controlled to drive the counterweight 310 to move a certain length.

[0052] For example, the first sensor 410 and the second sensor 420 may be pressure sensors. The winding shaft 210 may be rotatably connected to the moving device 100 via two bearings. The positions of the two bearings are the two preset points mentioned above. The first sensor 410 and the second sensor 420 are respectively located below the two bearings.

[0053] In some other embodiments, the first sensor 410 and the second sensor 420 described above can also be located at the drive wheels on opposite sides of the moving device 100. They can also determine the pressure on both sides of the moving device 100, thereby controlling the second drive component 320 to drive the counterweight 310 to move a certain distance and balance the weight on both sides.

[0054] Regarding the specific structure of the mobile device 100, as follows: Figure 2 As shown, in some embodiments, the moving device 100 may include a moving body 110 and a lifting component 120, wherein the moving body 110 is connected to the take-up shaft 210 through the lifting component 120, so that the height of the take-up shaft 210 can be controlled by the lifting component 120 to be suitable for removing auxiliary materials 20 from workpieces 10 of different heights.

[0055] For example, the mobile body 110 can be an AGV (Automated Guided Vehicle) or other equipment with self-moving capabilities. The lifting component 120 can be an electric cylinder, a pneumatic cylinder, or other lifting structure. The aforementioned first drive component 220 and second drive component 320 can be located inside the mobile body 110 and connected to the corresponding take-up shaft 210 and counterweight 310 via a transmission structure, thereby optimizing the overall structure, ensuring aesthetics, and simultaneously ensuring the chassis weight of the mobile device 100, further reducing the risk of the mobile device 100 tipping over.

[0056] Furthermore, the moving device 100 may also include a rotating component 130. The moving body 110 is connected to the lifting component 120 via the rotating component 130, or the lifting component 120 is connected to the take-up shaft 210 via the rotating component 130, so that the rotating component 130 can drive the take-up shaft 210 to rotate about an axis perpendicular to the take-up shaft 210. In this way, when the take-up shaft 210 has wound up a sufficient weight, or when the auxiliary material 20 has been wound up, the rotating component 130 can drive the take-up shaft 210 to rotate and disengage from directly above the workpiece 10 for unloading. It should be noted that the axis of rotation of the rotating component 130 driving the take-up shaft 210 is perpendicular to the axis of the take-up shaft 210.

[0057] For example, the rotating component 130 may be an indexing plate or a turntable structure driven by a motor.

[0058] In some embodiments, such as Figure 2 and Figure 5As shown, the auxiliary material removal device may also include a pushing structure, which is mounted on the moving device 100 and is used to automatically remove the auxiliary material 20 wound on the winding shaft 210 from the winding shaft 210.

[0059] Specifically, the pushing structure includes a pushing component 510 and a third driving component 520. The third driving component 520 is mounted on the moving device 100. The third driving component 520 drives the pushing component 510 to move along the axis of the take-up shaft 210, thereby pushing the auxiliary material 20 wound by the take-up shaft 210 out of the take-up shaft 210, eliminating the need for manual unloading and improving efficiency.

[0060] The third drive component 520 may be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, or other structures with extension and retraction functions.

[0061] In some embodiments, the pushing component 510 may include a push plate 511, and a third driving component 520 is connected to the push plate 511. The third driving component 520 is used to push the push plate 511 to push out the auxiliary material 20 on the take-up shaft 210.

[0062] For example, the push plate 511 can be sleeved on the take-up shaft 210, or the push plate 511 can be arranged at least partially around the take-up shaft 210, so that the take-up shaft 210 can provide a certain support for the push plate 511 without affecting the rotation of the take-up shaft 210.

[0063] Furthermore, the pushing component 510 also includes at least one first cutting blade 512, which is connected to the push plate 511 and is located in front of the push plate 511 along the extension direction of the pushing component 510. In this way, when the third driving component 520 drives the pushing component 510 to extend, the first cutting blade 512 can first cut the rolled auxiliary material 20 on the take-up shaft 210, while the push plate 511 pushes out the auxiliary material 20 cut into strips that are still attached to the take-up shaft 210. This avoids the situation where the friction between the rolled auxiliary material 20 and the take-up shaft 210 is too great and cannot be pushed out, thus facilitating the unloading operation.

[0064] For example, there are multiple first cutting blades 512, which are arranged at intervals around the axis of the take-up shaft 210. There may be two, three, or four first cutting blades 512, etc. Preferably, the multiple first cutting blades 512 are arranged in a circular array around the axis of the take-up shaft 210.

[0065] When the auxiliary material 20 wound by the winding shaft 210 exceeds the weight that the counterweight structure can balance, the auxiliary material removal equipment needs to first cut and separate the wound auxiliary material 20 from the unwound auxiliary material 20 before ejecting it, and then rewind the remaining auxiliary material 20. This means that for auxiliary materials 20 with large weight, multiple windings are required to remove them all.

[0066] In some embodiments, the auxiliary material removal device may further include a cutting structure to automatically cut the auxiliary material 20, separating the wound auxiliary material 20 from the unwound auxiliary material 20, thereby eliminating the need for manual cutting and improving the removal efficiency of the auxiliary material 20.

[0067] Specifically, such as Figure 2 and Figure 6 As shown, the cutting structure includes a second cutting blade 610 and a fourth driving component 620. The fourth driving component 620 is mounted on the moving device 100 and connected to the second cutting blade 610. The fourth driving component 620 drives the second cutting blade 610 to move along the axis of the winding shaft 210. In this way, when the auxiliary material 20 wound by the winding shaft 210 reaches the weight that the counterweight structure can balance or the preset weight, the second cutting blade 610 can be extended by the fourth driving component 620 to cut and separate the wound auxiliary material 20 from the unwound auxiliary material 20, thus eliminating the need for manual cutting and improving the removal efficiency of the auxiliary material 20.

[0068] For example, the third drive component 520 may be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, or other structure with extension and retraction functions.
