Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of wind turbine blade processing, and in particular to a robot and a method for removing residual glue in a wind turbine blade. Background Art
[0002] Wind turbine blades are made by bonding shells together with adhesive. The adhesive is manually applied to the webs, spar caps, and leading and trailing edges. The blades are then molded together using a tooling tool. Excess glue overflows after the mold is closed. A lot of glue squeezes out of the leading edge, the middle of the web, and the trailing edge, and hangs on the edges of the bonding corners. The narrow and dim interior of the wind turbine blade makes it difficult for workers to clean up the excess glue. This residual glue can fall off during blade operation, creating noise and damaging the partitions and blade tip housings, lightning protection systems, and drain holes, posing a significant quality risk.

[0022] The beneficial effects brought about by the technical solution provided by the embodiments of the present invention are:
[0023] 1. The present invention provides a robot and method for removing residual glue from wind turbine blades. The collection mechanism of the glue removal module squeezes the residual glue into the grooves on the surfaces of the two rollers, and then squeezes out the residual glue in the grooves through the scraper. The collected residual glue is then output through the transfer mechanism. This solves the problem that the residual glue is highly viscous and has poor fluidity and is difficult to collect, as well as the problem of removing residual glue in areas of wind turbine blades that are inaccessible to humans. By driving the glue removal module with a mobile trolley, the residual glue on the wind turbine blades can be continuously removed, thereby achieving continuous and efficient removal of residual glue.
[0024] 2. The present invention provides a robot and method for removing residual glue in wind turbine blades. When the curvature and slope of the glue removal surface in the wind turbine blade change, the collection mechanism of the glue removal module moves along with the change of the glue removal surface. The collection mechanism drives the slider in the compliance mechanism to slide, causing the elastic member to expand and contract to adjust the state, thereby making the collection mechanism comply with the change of the glue removal surface. At the same time, the elastic member also provides a pre-tightening force for the collection mechanism, so that it can better fit the glue removal surface, thereby enhancing the adaptability of the glue removal module and ensuring that the residual glue can still be cleaned when the glue removal surface changes.
[0025] 3. A robot and method for removing residual glue from wind turbine blades of the present invention adjusts the height of the web side glue removal module through a first adjusting mechanism, and cooperates with a compliance mechanism to adjust the position of a collecting mechanism so that the collecting mechanism of the web side glue removal module is always in contact with the glue removal surface on one side of the web, so that the web side glue removal module continuously removes the residual glue on one side of the web, and adjusts the deflection angle and horizontal displacement of the leading edge side glue removal module through a second adjusting mechanism, and cooperates with the compliance mechanism to adjust the position of the collecting mechanism so that the collecting mechanism of the leading edge side glue removal module is in contact with the glue removal surface on one side of the leading edge on the gradually narrowing leading edge side, so that the leading edge side glue removal module continuously removes the residual glue on one side of the leading edge, thereby realizing active compliance of the glue removal module when the curvature of the glue removal surface where the residual glue inside the wind turbine blade is located changes, thereby improving the efficiency and effect of removing the residual glue.
[0026] 4. The present invention provides a robot and method for removing residual glue from wind turbine blades. The rollers of the mobile trolley cooperate with the steering wheel at the bottom of the base plate, and utilize the principle that three points form a plane to achieve the robot's passive compliance to changes in the curved surface and flexible omnidirectional movement with three degrees of freedom in two dimensions on the curved surface. This can effectively prevent the wheels from being suspended in the air, effectively prevent the vehicle body from overturning, and improve the stability of the movement. In addition, the steering wheel can independently control the steering, so that the steering wheel has the ability to steer, thereby enabling the robot to patrol the line in the narrow environment inside the wind turbine blade.

Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.
[0049] Please refer to Figure 1 An embodiment of the present invention provides a robot for removing residual glue from wind turbine blades, which mainly includes a mobile car 1, a glue storage module 2, two glue removal modules 3, a first adjustment mechanism and a second adjustment mechanism 5.
[0050] The mobile car 1 is used to pull the robot for removing residual glue from wind turbine blades. Figure 2 and 3 As shown, the mobile vehicle 1 mainly includes a tractor 101 and a chassis 104. The tractor 101 can be a four-wheeled walking robot or a two-wheeled walking robot. In this embodiment, the tractor 101 is a four-wheeled walking robot. A cable 103 is provided at the rear end of the tractor 101 to supply power to the tractor 101. If the tractor 101 becomes stuck or otherwise unable to move, the cable 103 can be used to pull the tractor 101 out. In addition, considering the working environment, the tractor 101 can be waterproof and dustproof.
[0051] The chassis 104 is connected to the front of the tractor 101. A steering wheel frame 105, a plurality of steering wheels 106, and a steering wheel drive component 107 are provided at the bottom of the front end of the chassis 104. The steering wheel frame 105 is provided in the middle of the front end of the chassis 104. The steering wheels 106 can be provided in a plurality according to actual needs. For example, in this embodiment, the steering wheels 106 are provided in three. The steering wheel frame 105 is a U-shaped frame, and all the steering wheels 106 are rotatably installed side by side in the steering wheel frame 105. The steering wheels support the front end of the chassis 104, and the steering wheels 106 cooperate with the two rollers 102 at the front end of the tractor 101 to form a stable supporting triangle. By utilizing the principle that three points form a plane, the steering wheels and the rollers 102 of the tractor 101 can stably move on the curved surface with constantly changing curvature inside the wind turbine blade.
[0052] The steering wheel driving component 107 is arranged on the upper part of the steering wheel frame 105. The steering wheel driving component 107 is generally a steering gear. The steering gear is connected to the steering wheel frame 105 and drives the steering wheel frame 105 to rotate, thereby driving each steering wheel 106 to rotate. In this way, the steering of the chassis 104 can be controlled by the steering gear.
[0053] Continue as Figure 3 As shown, the glue storage module 2 is disposed on the mobile vehicle 1. The glue storage module 2 mainly includes a glue storage bin 201, which is approximately a rectangular parallelepiped and has two glue inlet pipes 202 at the top. The glue storage bin 201 is fixedly mounted on the chassis 104. The glue storage bin 201 has a large volume and can store collected residual glue for reuse.
[0054] like Figure 4 and 5 As shown, the two adhesive removal modules 3 are a web-side adhesive removal module 3a and a leading-edge-side adhesive removal module 3b, respectively provided on both sides of the mobile vehicle 1. The web-side adhesive removal module 3a is used to remove adhesive residue on the web side of the wind turbine blade, while the leading-edge-side adhesive removal module 3b is used to remove adhesive residue on the leading edge side of the wind turbine blade.
[0055] Specifically, each of the adhesive removal modules 3 mainly includes a collecting mechanism 31 , a conforming mechanism 32 and a transporting mechanism 33 .
[0056] like Figure 6 and 7 As shown, the collecting mechanism 31 is used to collect residual adhesive inside the wind turbine blade. The collecting mechanism 31 mainly includes a shell, two rollers 313, two scrapers 317 and a first driving component arranged in the shell.
[0057] The front end of the shell is open, and the residual glue to be collected can enter from the front end of the shell. The shell can be flexibly set to various shapes according to actual application needs. For example, in this embodiment, the front part of the shell is a rectangular parallelepiped, and the rear part is provided with a cylindrical rear joint, which is arranged at an angle. The shell is specifically composed of a lower shell 311 and an upper cover plate 312. The upper cover plate 312 covers the upper port of the shell 311. In order to facilitate the entry of residual glue into the shell, the edges of the front port of the shell are all set with cutting edges.
[0058] The two rollers 313 are arranged side by side, both of which are vertically arranged and approximately in contact with each other. The surface of each roller 313 is provided with multiple grooves. When the two rollers 313 rotate, the residual film in front of the two rollers 313 is rolled up and squeezed into the grooves.
[0059] like Figure 7 As shown, the grooves include circumferential grooves 313a, each of which is disposed circumferentially around the roller 313 and is evenly spaced along the axial direction of the roller 313. Furthermore, the grooves may also include axial grooves 313b, each of which is disposed axially along the roller 313 and is spaced circumferentially along the roller 313. The axial grooves 313b cooperate with the circumferential grooves 313a to entrain more residual adhesive.
[0060] Each scraper 317 is positioned behind one of the rollers 313. A protruding tooth 317a is provided at the front end of each scraper 317, which inserts into a groove in one of the rollers 313. The shape of the protruding tooth 317a matches the shape of the groove, specifically the shape of the circumferential groove 313a, so that the protruding tooth 317a fits within the groove. As the two rollers 313 rotate, the protruding tooth 317a precisely scrapes away residual adhesive from the circumferential groove 313a. The shapes of the protruding teeth 317a and the circumferential groove 313a can be flexibly configured based on the actual application scenario. For example, in this embodiment, the cross-section of the circumferential groove 313a is rectangular, and the protruding teeth 317a are rectangular blocks.
[0061] The first driving component is connected to the two rollers 313 to drive the two rollers 313 to rotate in opposite directions. The first driving component includes a first driving motor 316 and a first gear set driven by the first driving motor 316.
[0062] The first gear set includes a plurality of first gears 314 meshed in sequence. Figure 6As shown, in this embodiment, the first gear set includes four first gears 314 that are meshed in sequence. The four first gears 314 are installed on the upper part of the upper cover plate 312 and are arranged in a straight line. A gear cover 315 is provided above the upper cover plate 312, and the four first gears 314 are arranged in the gear cover 315.
[0063] Furthermore, the two first gears 314 are respectively connected to the two rollers 313. The two first gears 314, located at the edges, are respectively mounted on two rotating shafts 318. The lower end of each rotating shaft 318 is rotatably mounted on the bottom surface of the housing 311 via a first bearing. The two rollers 313 are respectively mounted on the two rotating shafts 318. The first drive motor 316 is fixed to the gear cover 315, and the output shaft of the first drive motor 316 extends into the gear cover 315 and is connected to the upper end of one of the rotating shafts 318 via a coupling. In this way, the first drive motor 316 can drive the first gear train, causing the two rollers 313 to rotate in opposite directions.
[0064] Recombination Figure 6 and 8 As shown, the compliant mechanism 32 is connected to the collection mechanism 31 so that the collection mechanism 31 can rotate adaptively. The compliant mechanism 32 mainly includes a base plate 321 and a plurality of sliding parts. The base plate 321 is provided with a plurality of arc-shaped chutes 322. The base plate 321 is a hollow flange plate. The chutes 322 are coaxially arranged with the base plate 321. Generally, the number of the chutes 322 can be flexibly set to multiple, and the arc lengths of the chutes 322 are the same and are evenly distributed on a circumference. As described in this embodiment, the number of chutes 322 is set to three.
[0065] The number of the sliding members is consistent with the number of the chute 322. Each sliding member is disposed in a chute 322 and includes a slider 323 and two elastic members 324. The slider 323 is slidably disposed in the chute 322. The slider 323 is an arc-shaped block with a diameter and width substantially the same as those of the chute 322, so that the slider 323 is embedded in the chute 322 and can slide along the chute 322.
[0066] The elastic members 324 are generally springs. The two ends of the slider 323 are respectively connected to one end of the two elastic members 324, and the other ends of the two elastic members 324 are respectively connected to the two ends of the chute 322. Each slider 323 is connected to the rear end of the shell, specifically, it is tightly connected to the rear joint of the shell. When the collection mechanism 31 is not rotating, the elastic members 324 maintain their normal length. When the collection mechanism 31 rotates, one elastic member 324 in each chute 322 extends and the other elastic member 324 compresses, causing the compliance mechanism 32 to automatically adapt to the rotation of the collection mechanism 31.
[0067] like Figure 9 As shown, the transfer mechanism 33 is used to output the residual rubber collected at the rear of the housing of the collection mechanism 31. The transfer mechanism 33 can generally be a screw conveyor. In this embodiment, the screw conveyor includes a rubber transfer hose 331, a spiral blade 332, and a second drive component.
[0068] The front end of the transfer tube 331 is connected to the compliance mechanism 32. Specifically, the outer wall of the front end of the transfer tube 331 is provided with a connecting flange 334, the front end of the transfer tube 331 is inserted into the base plate 321 and docked with the rear joint, and the connecting flange 334 is attached to and tightly connected to the base plate 321.
[0069] The rear end of the second driving component is connected to the second driving component. The spiral blade 332 is arranged in the rubber transfer tube 331. A rubber outlet tube 331a is provided on one side of the rubber transfer tube 331. The second driving component is connected to the rear end of the spiral blade 332.
[0070] Specifically, the second drive component primarily comprises a second drive motor 333, a motor base 335, a motor conversion shaft 336, a motor blade connector 337, and bearings. The second drive motor 333 is typically a brushless motor. The motor base 335 is fixedly connected to the upper end of the transfer hose 331. The second drive motor 333 is mounted on the motor base 335, and the motor conversion shaft 336 and motor blade connector 337 are disposed within the motor base 335. The output end of the second drive motor 333 is connected to the motor conversion shaft 336, which is configured as a rectangular block. The motor blade connector 337 is cylindrical with a rectangular slot at its upper end. The motor conversion shaft 336 is inserted into the upper end of the motor blade connector 337 and is securely connected thereto.
[0071] The second bearing 338 is mounted inside the upper end of the rubber transfer tube 331. The upper end of the spiral blade 332 passes through the second bearing 338 and is securely connected to the lower end of the motor blade connector 337. An oil seal 339 is also mounted on the second bearing 338. The second drive motor 333 drives the spiral blade 332 to rotate, causing residual rubber at the lower end of the spiral blade 332 to spiral upward and be squeezed out of the rubber outlet tube 331a.
[0072] Here, the two glue inlet pipes 202 of the glue storage bin 201 are respectively connected to the transfer mechanisms 33 of the two glue removal modules 3, that is, the glue outlet pipe 331a of each glue removal module 3 is connected to one glue inlet pipe 202 of the glue storage bin 201, so that the residual glue squeezed out from the glue outlet pipe 331a is transported to the glue storage bin 201 for storage.
[0073] When the glue removal module 3 is working, it moves inside the wind turbine blade, so that the lower edge of the front port of the shell of the collection mechanism 31 fits with the glue removal surface inside the wind turbine blade, so that the residual glue on the glue removal surface enters the shell and gradually accumulates. Then, under the driving action of the first driving mechanism, the two rollers 313 rotate in opposite directions, rolling up the residual glue in the shell, so that the residual glue is squeezed into the circumferential groove 313a and the axial groove 313b on the surface of the roller 313. At the same time, the scraper 317 uses the convex teeth 317a to scrape out the residual glue in the circumferential groove 313a, and the residual glue in the axial groove 313b will fall after the residual glue in the circumferential groove 313a is scraped out. In this way, the residual glue is collected at the rear of the shell, located at the lower end of the glue transfer tube 331. Thereafter, driven by the second driving motor 333 , the spiral blades 332 convey the collected residual glue in a spiral upward direction, and under the squeezing effect, the residual glue is output from the glue outlet pipe 331 a to the glue storage bin 201 .
[0074] like Figure 10 and 11 As shown, the web side degumming module 3a is installed on the mobile trolley 1 through the first adjusting mechanism 4. Specifically, the first adjusting mechanism 4 includes a rotating seat 401, a third driving component 402, a first screw assembly 403 and a telescopic cylinder 404.

[0081] like Figure 14 As shown, an embodiment of the present invention further provides a method for removing residual adhesive from a wind turbine blade, using the aforementioned residual adhesive removal robot for a wind turbine blade, and comprising the following steps:
[0082] S1. Before the wind turbine blade 100 is molded, the mobile trolley 1 is controlled to move from the root of the wind turbine blade 100 to the tip of the blade, so that the web-side debonding module 3a is close to the inner web 100a side of the wind turbine blade 100, and the leading edge-side debonding module 3b is close to the inner leading edge side of the wind turbine blade 100.
[0083] As the mobile trolley 1 moves, the residual glue on one side of the web 100a will enter the web side glue removal module 3a, and at the same time, the residual glue on the leading edge side will enter the leading edge side glue removal module 3b. The residual glue entering the two glue removal modules will be collected by the collecting mechanism 31 and output through the transfer mechanism 33.
[0084] S2. Adjust the height of the web side glue removal module 3a through the first adjustment mechanism so that the front end of the shell of the collection mechanism 31 of the web side glue removal module 3a continues to fit with the glue removal surface on one side of the web 100a, collect the residual glue on one side of the web 100a, and transport the collected residual glue to the glue storage module 2 through the transfer mechanism 33.
[0085] The bottom surface of one side of the web 100a of the wind turbine blade 100 is approximately an inclined plane, and the residual glue mainly changes in height. Therefore, the height of the web side glue removal module 3a is adjusted by the first adjustment mechanism, that is, the height of the front port of the shell of the collection mechanism 31 is adjusted, so that the front port of the shell is always in contact with the glue removal surface on one side of the web 100a, so as to realize continuous collection of the residual glue on one side of the web 100a.
[0086] S3. Adjust the deflection angle and horizontal displacement of the leading edge side glue removal module 3b through the second adjustment mechanism 5 so that the front end of the shell of the leading edge side glue removal module 3b continues to fit with the glue removal surface on the side of the leading edge 100b, collect the residual glue on the side of the leading edge 100b, and transport the collected residual glue to the glue storage module 2 through the transfer mechanism 33.
[0087] The bottom surface on one side of the leading edge 100b of the wind turbine blade 100 is a curved surface with a constantly changing curvature, and the height and horizontal position of the residual glue will change. Therefore, the fourth driving component of the second adjusting mechanism 5 is used to adjust the horizontal movement of the leading edge side glue removal module 3b, and the fifth driving component 506 is used to adjust the rotation of the leading edge side glue removal module 3b to adjust the position of the front port of the shell of the collection mechanism 31, so that the front port of the shell is always in contact with the glue removal surface on the side of the leading edge 100b, so as to realize continuous collection of the residual glue on one side of the leading edge 100b.
