Description

Technical Field

[0001] This invention belongs to the field of automation technology, specifically relating to a device and method for winding bolt sleeves on wind turbine blades. Background Technology

[0002] In the field of wind turbine blade manufacturing, after the bolt sleeve is sandblasted to remove rust and increase its surface roughness, it is necessary to wrap several layers of fiberglass filaments around its surface to improve the effective bonding function with the wind turbine blade. In the existing technology, the wire wrapping process for wind turbine blade bolt sleeves mainly adopts a semi-automatic wire wrapping scheme. That is, a bolt sleeve is manually inserted into a mandrel with a rotating power, and several fiberglass filaments are manually pressed onto the surface of the bolt sleeve. The mandrel is started to rotate, and the fiberglass filaments slide between the fingers. The thickness and uniformity of the wire wrapping are controlled by the translation speed of the hand. After the wire wrapping is completed, the ends of the fiberglass filaments are cut off and knotted by hand to prevent the fiberglass filaments from scattering. After completion, the wire-wrapped bolt sleeves are removed and placed in an orderly manner.

[0003] However, the bolt sleeve is relatively heavy, and manual operation is inefficient. The winding quality is unstable and it is easy to loosen. This can cause the wind turbine to malfunction or even cause a major accident if the connecting bolts loosen during operation. Moreover, the fiberglass filaments are very sharp and can easily cut fingers during manual winding. There is no safety protection during the rotation of the bolt sleeve, which poses a safety hazard. In addition, the fiberglass dust is very harmful to the human body if inhaled.

[0004] In summary, there is an urgent need for a wind turbine blade bolt sleeve winding device and method that can automate the bolt sleeve winding operation in the wind power industry and solve the problems of low efficiency, unstable quality and high production cost of manual winding. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for winding bolt sleeves of wind turbine blades that can realize automated and digital production of bolt sleeves in the wind power industry, and solve the problems of low efficiency, unstable quality and high cost of manual winding.

[0006] The above objective is achieved through the following technical solution: a wind turbine blade bolt winding device, comprising a workbench and a lifting support assembly, a tightening assembly, a translational wire feeding assembly, a knotting assembly, and a wire cutting assembly disposed on the workbench. The tightening assembly includes a tightening drive mechanism, a rotary drive mechanism, a movable support, and a fixed support. The movable support and the fixed support are respectively provided with a movable end positioning sleeve and a fixed end positioning sleeve. The rotary drive mechanism is pultrusively connected to the fixed end positioning sleeve and is used to drive the fixed end positioning sleeve to rotate. The fixed end positioning sleeve is rotatably connected to the fixed support. The fixed end positioning sleeve and the movable end positioning sleeve are disposed opposite to each other. The clamping drive is connected to the movable support and drives the movable support to move axially along the fixed end positioning sleeve. The movable end positioning sleeve contains a clamp telescopic drive, which drives the wire-winding clamp to move axially along the movable end positioning sleeve and extends to the surface of the wind turbine blade bolt sleeve on the movable end positioning sleeve. The fixed support has a strut telescopic drive, which is connected to a knotting strut and drives the knotting strut to move axially along the fixed end positioning sleeve. The knotting strut is located on one side of the fixed end positioning sleeve and is parallel to the fixed end positioning sleeve. A lifting support assembly is located below the tightening assembly. The lifting support assembly includes a lifting drive and a support. The lifting drive is connected to the support and drives the support to move the wind turbine blade bolt sleeve up and down. A translational wire feeding assembly is located on one side of the tightening assembly. The translational wire feeding assembly includes a translational track, a translational drive, and a wire feeding component. The wire feeding component includes a translational support, a wire feeding drive, a wire feeding clamp, a take-up roller, a tension control roller, and a take-up drive. The translational track is arranged on the worktable along the axial direction of the movable end positioning sleeve. The translational support is located on the translational track. The moving component is driven by the translation support and is used to drive the translation support to move along the translation track. The translation support is provided with a wire passage. The wire feeding drive, the wire take-up roller, the tension control roller and the wire take-up drive are arranged on the translation support. The wire take-up drive is driven by the wire take-up roller. The wire feeding drive is driven by the wire feeding clamp and is used to drive the wire feeding clamp to move closer to or away from the wind turbine blade bolt sleeve fixed on the tightening assembly. The knotting assembly is provided with a knotting clamp and is used to cooperate with the knotting support rod to pull the glass fiber filaments to complete the knotting. The wire cutting assembly includes a wire cutting blade and is used to cut the knotted glass fiber filaments.

[0007] This invention relates to the wire winding of wind turbine blade bolt sleeves. During application, the wind turbine blade bolt sleeve is first placed on the support of a lifting support assembly. After the fiberglass filament passes through the wire feeding channel, it passes through the take-up roller and tension control roller, and then the wire feeding clamp holds the fiberglass filament. The lifting drive of the lifting support assembly drives the support to move the wind turbine blade bolt sleeve upwards until the axis of the wind turbine blade bolt sleeve is aligned with the axes of the movable end positioning sleeve and the fixed end positioning sleeve, thus completing the positioning of the wind turbine blade bolt sleeve. The tightening drive then drives the movable support to move towards the fixed support until the movable end positioning sleeve and the fixed end positioning sleeve... The wind turbine blade bolt sleeve is tightened and fixed, and the lifting support assembly is reset. The translational wire feeding assembly moves to deliver the fiberglass filament directly above the wind turbine blade bolt sleeve. The clamp extension drive extends the wire-winding clamp to the movable end positioning sleeve and clamps the fiberglass filament on the wire feeding clamp. The rotation drive slowly rotates the fixed end positioning sleeve, which in turn rotates the movable end positioning sleeve and the wind turbine blade bolt sleeve together, slowly winding the fiberglass filament onto the wind turbine blade bolt sleeve. Simultaneously, the translational drive drives the entire wire feeding assembly to reciprocate along the translational track, causing the fiberglass filament to be self-pressed onto the surface of the wind turbine blade bolt sleeve, completing the winding process. The fiberglass filament end is tightly wound onto the surface of the bolt sleeve; then the wire clamping and winding clamp releases the fiberglass filament, and the clamp extension and retraction drive drives the wire clamping and winding clamp to retract and reset; the rotation drive drives the fixed end positioning sleeve to rotate faster, while the translation drive drives the entire wire feeding component to accelerate and reciprocate along the translation track, evenly wrapping the fiberglass filament around the entire surface of the wind turbine blade bolt sleeve. After wrapping, the translation wire feeding assembly stops near the knotting assembly, and the rotation drive stops; the strut extension and retraction drive drives the knotting strut to extend between the fiberglass filament and the wind turbine blade bolt sleeve, and the rotation drive slowly rotates again. The fiberglass filaments are wound onto the knotting support rod to form a knot loop, and then the rotation drive stops rotating; the clamp of the knotting assembly extends into the knot loop to clamp the fiberglass filaments, and then the support rod extension drive drives the knotting support rod to reset and retract, the knotting support rod disengages from the knot loop, the clamp of the knotting assembly retracts, and the clamped part of the fiberglass filament is pulled out of the knot loop. The rotation drive slowly rotates again to self-press the fiberglass pulled out of the knot loop to form a knot, and the wire feeding assembly drives the wire feeding clamp to extend to tighten the knot, completing the knotting; the wire cutting assembly drives the wire cutting blade to cut the wire, and after the wire cutting is completed, the wire cutting assembly resets.

[0008] In practical applications, the clamping drive, clamp extension drive, strut extension drive, and lifting drive are cylinders, while the rotating drive, wire feeding drive, and wire take-up drive are motors.

[0009] A further technical solution is that the fiber passage is equipped with a partition rod, which divides the fiber passage into several channels. This arrangement ensures that each fiberglass filament is independent and maintains consistent tension under the pressure of the tension roller.

[0010] A further technical solution is that the knotting assembly further includes a knotting support, a primary telescopic cylinder, and a secondary telescopic cylinder. The knotting clamp is fixedly connected to the movable end of the secondary telescopic cylinder, the secondary telescopic cylinder is fixedly connected to the movable end of the primary telescopic cylinder, the primary telescopic cylinder is fixed to the knotting support, and the knotting assembly is fixed to the worktable via the knotting support. This design allows for precise control of the knotted wire length.

[0011] A further technical solution is that the lifting support assembly also includes a fixing component and an adjusting plate. The lifting drive component is connected to the adjusting plate via locking bolts. The fixing component has a U-shaped groove, and the adjusting plate is disposed within the U-shaped groove. The adjusting plate is movably connected to the fixing component via height adjusting bolts. The lifting support assembly is fixed to the worktable via the fixing component. With this configuration, the center height of the wind turbine blade bolt sleeve can be adjusted via the adjustable bolts, ensuring that the axis of the wind turbine blade bolt sleeve is aligned with the axis of the fixed end positioning sleeve.

[0012] A further technical solution is that the wire cutting assembly also includes a mounting plate, a wire cutting drive cylinder, a wire cutting motor, a connecting rod, and a tension spring. The wire cutting motor is fixed to the connecting rod. The fixed end of the drive cylinder is fixed to the mounting plate, and its movable end is connected to the connecting rod. The connecting rod is hinged to the mounting plate. One end of the tension spring is connected to the connecting rod, and the other end is connected to the mounting plate. The wire cutting blade is connected to the output shaft of the wire cutting motor. The wire cutting assembly is fixed to the worktable via the mounting plate. With this configuration, the wire cutting drive cylinder extends and retracts to drive the wire cutting blade to cut wires, and the retraction of the wire cutting drive cylinder drives the wire cutting blade to rise and reset.

[0013] A further technical solution is that the support member is provided with a V-shaped groove that matches the size of the wind turbine blade bolt sleeve.

[0014] A further technical solution is that the worktable is provided with a guide rail and a support rod slider, and the movable support and the knotted support rod are respectively slidably mounted on the guide rail and the support rod slider.

[0015] A further technical solution is that the workbench has a tabletop, and a space for placing fiberglass filament rolls is provided under the tabletop.

[0016] A further technical solution is that the translational wire feeding assembly also includes a sandblasting quality inspection component and a wire winding quality inspection component. The sandblasting quality inspection component includes a color difference sensor, which is mounted on the translational support via a mounting bracket. The color difference sensor is used to inspect the quality of the placed wind turbine blade bolt sleeves. The wire winding quality inspection component includes a laser measurement sensor, which is mounted on the translational support via a mounting bracket. The laser measurement sensor is used to measure and inspect the wire winding thickness of the wind turbine blade bolt sleeves after wire winding. With this configuration, the color difference sensor is used to inspect the quality of the sandblasted wind turbine blade bolt sleeves. If there are no quality issues, the wire winding process continues. If a quality problem is detected in the sandblasting of the bolt sleeve, the machine automatically rejects it. The laser measurement sensor is used to measure and inspect the wire winding thickness of the completed wind turbine blade bolt sleeves, ensuring the uniformity and thickness of the wire winding.

[0017] To achieve the above objectives, the present invention also provides a method for winding wire around the bolt sleeve of a wind turbine blade, which employs any of the wind turbine blade bolt sleeve winding devices described above, and includes the following steps:

[0018] (1) Place the wind turbine blade bolt sleeve on the support of the lifting support assembly;

[0019] (2) After passing through the fiber channel, the fiber filaments are taken up by the take-up roller and the tension control roller, and then the fiber feed clamps hold the fiber filaments.

[0020] (3) The lifting drive component of the lifting support assembly drives the support component to move the wind turbine blade bolt sleeve upward until the axis of the wind turbine blade bolt sleeve is consistent with the axis of the movable end positioning sleeve and the fixed end positioning sleeve.

[0021] (4) The driving component drives the movable support to move toward the fixed support until the movable end positioning sleeve and the fixed end positioning sleeve tighten and fix the wind turbine blade bolt sleeve, and the lifting support assembly is reset.

[0022] (5) The translation wire feeding assembly moves to deliver the fiberglass wire directly above the wind turbine blade bolt sleeve;

[0023] (6) The clamp extension drive drives the wire clamp to extend to the movable end positioning sleeve and clamps the fiberglass wire on the wire feeding clamp, guiding the fiberglass wire to the surface of the wind turbine blade bolt sleeve.

[0024] (7) The rotary drive drives the fixed end positioning sleeve to rotate slowly, which in turn drives the movable end positioning sleeve and the wind turbine blade bolt sleeve to rotate together, slowly winding the fiberglass wire onto the wind turbine blade bolt sleeve. At the same time, the translation drive drives the wire feeding part to reciprocate along the translation track, so that the fiberglass wire is self-pressed onto the surface of the wind turbine blade bolt sleeve, completing the winding of the fiberglass wire end onto the surface of the bolt sleeve. Then the wire clamping and winding clamps release the fiberglass wire, and the clamp extension and retraction drive drives the wire clamping and winding clamps to retract and reset.

[0025] (8) The rotary drive drives the fixed end positioning sleeve to accelerate rotation, while the translation drive drives the wire feeding part to accelerate and reciprocate along the translation track, so that the glass fiber is evenly wrapped around the entire surface of the wind turbine blade bolt sleeve. After the wrapping is completed, the translation wire feeding assembly stops near the knotting assembly, and the rotation of the fixed end positioning sleeve is paused.

[0026] (9) The strut extension drive drives the knotted strut to extend between the fiberglass wire and the wind turbine blade bolt sleeve. The rotation drive slowly rotates again to wrap the fiberglass wire around the knotted strut to form a knotted loop. Then the rotation drive stops rotating.

[0027] (10) The clamp of the knotting component extends into the knotting ring to clamp the glass fiber filament. Then the strut extension drive drives the knotting strut to reset and retract. The knotting strut disengages from the knotting ring, and the clamp of the knotting component retracts. The clamped part of the glass fiber filament is pulled out of the knotting ring. The rotation drive slowly rotates again to self-press the glass fiber pulled out of the knotting ring to form a knot. The wire feeding drive of the translational wire feeding component drives the wire feeding clamp to extend and tighten the knot to complete the knotting. Repeat the above actions to knot multiple times to ensure that the glass fiber filament does not loosen.

[0028] (11) The cutting component drives the cutting blade to cut the wire. After the cutting is completed, the cutting component resets.

[0029] A further technical solution is that, before step (5), a step of using a color difference sensor to perform quality inspection on the sandblasting of the wind turbine blade bolt sleeve is included: during the rotation of the wind turbine blade bolt sleeve, the translational wire feeding assembly drives the color difference sensor to move back and forth to perform precise inspection on the surface of the wind turbine blade bolt sleeve. If no quality problem is detected in the sandblasting of the wind turbine blade bolt sleeve, then step (6) is performed; if a quality problem is detected in the sandblasting of the wind turbine blade bolt sleeve, then the wind turbine blade bolt sleeve is removed and step (1) is performed. After step (11), a step of using a laser ranging sensor to detect the winding thickness of the wind turbine blade bolt sleeve is included: the translational wire feeding assembly drives the laser measuring sensor to move back and forth to measure and inspect the winding thickness of the wind turbine blade bolt sleeve after winding, to ensure that the uniformity and thickness of the winding meet the process standards, and to store the measurement data to generate a production report.

[0030] Compared to existing technologies, this invention uses a lifting support assembly to transport the wind turbine blade bolt sleeve to a predetermined position, then uses a tightening mechanism to tighten it, and a translational wire feeding assembly to wind the glass fiber filaments onto the surface of the bolt sleeve. The winding, knotting, and cutting processes are then automatically completed. This invention provides stable and consistent winding quality, automating the winding of bolt sleeves in the wind power industry and solving the problems of low efficiency, unstable quality, and high cost associated with manual winding in existing technologies.

The fiber cutting assembly 5 includes a fiber cutting blade 54 and is used to cut the knotted glass fiber filaments.

[0054] This invention relates to the winding of fiberglass filaments into wind turbine blade bolt sleeves 7. During application, the wind turbine blade bolt sleeve 7 is first placed on the support member 11 of the lifting support assembly 1. After the fiberglass filaments pass through the wire feeding channel 37, they pass through the take-up roller 34 and the tension control roller 36.

The tightening drive member 23 then drives the movable support 22 to move towards the fixed support 26 until the movable end positioning sleeve 25... The fixed end positioning sleeve 27 tightens and fixes the wind turbine blade bolt sleeve 7, and the lifting support assembly 1 resets; the translational wire feeding assembly 3 moves to deliver the fiberglass filament directly above the wind turbine blade bolt sleeve 7; the clamp extension drive drives the wire clamping and winding clamp 24 to extend to the movable end positioning sleeve 25 and clamp the fiberglass filament on the wire feeding clamp 33; the rotation drive 28 drives the fixed end positioning sleeve 27 to rotate slowly, thereby causing the movable end positioning sleeve 25 and the wind turbine blade bolt sleeve 7 to rotate together, slowly winding the fiberglass filament onto the wind turbine blade bolt sleeve 7.

[0063] Based on the above embodiments, in another embodiment of the present invention, such as... Figure 4 The translational wire feeding assembly 3 further includes a sandblasting quality inspection component and a wire winding quality inspection component. The sandblasting quality inspection component includes a color difference sensor 310, which is mounted on the translational support 39 via a mounting bracket. The color difference sensor 310 is used to inspect the quality of the placed wind turbine blade bolt sleeve 7. The wire winding quality inspection component includes a laser measurement sensor 311, which is mounted on the translational support 39 via a mounting bracket. The laser measurement sensor 311 is used to measure and inspect the wire winding thickness of the wind turbine blade bolt sleeve 7 after wire winding. With this configuration, the color difference sensor 310 is used to inspect the quality of the sandblasted wind turbine blade bolt sleeve 7. If there are no quality problems, the wire winding process continues. If a quality problem is detected in the sandblasting of the wind turbine blade bolt sleeve 7, the machine automatically rejects it. The laser measurement sensor 311 is used to measure and inspect the wire winding thickness of the completed wind turbine blade bolt sleeve 7, ensuring the uniformity and thickness of the wire winding.

[0064] The present invention also provides a method for winding wire around a wind turbine blade bolt sleeve 7, which is carried out using any of the wind turbine blade bolt sleeve winding devices described above, and includes the following steps:

[0065] (1) Place the wind turbine blade bolt sleeve 7 on the support member 11 of the lifting support assembly 1;

[0066] (2) After passing through the fiber channel 37, the fiber filament passes through the take-up roller 34 and the tension control roller 36, and then the fiber feed clamp 33 clamps the fiber filament.

[0067] (3) The lifting drive component 16 of the lifting support assembly 1 drives the support component 11 to move the wind turbine blade bolt sleeve 7 upward until the axis of the wind turbine blade bolt sleeve 7 is aligned with the axis of the movable end positioning sleeve 25 and the fixed end positioning sleeve 27.

[0068] (4) The push-tightening drive component 23 drives the movable support 22 to move toward the fixed support 26 until the movable end positioning sleeve 25 and the fixed end positioning sleeve 27 tighten and fix the wind turbine blade bolt sleeve 7, and the lifting support assembly 1 is reset.

[0069] (5) The translation wire feeding assembly 3 moves to deliver the fiberglass wire directly above the wind turbine blade bolt sleeve 7;

[0070] (6) The clamp extension drive drives the wire clamping and winding clamp 24 to extend to the movable end positioning sleeve 25 and clamps the glass fiber on the wire feeding clamp 33, guiding the glass fiber onto the surface of the wind turbine blade bolt sleeve 7.

[0071] (7) The rotary drive 28 drives the fixed end positioning sleeve 27 to rotate slowly, thereby driving the movable end positioning sleeve 25 and the wind turbine blade bolt sleeve 7 to rotate together, slowly winding the glass fiber onto the wind turbine blade bolt sleeve 7. At the same time, the translation drive drives the wire feeding part to reciprocate along the translation track 31, so that the glass fiber is self-pressed onto the surface of the wind turbine blade bolt sleeve 7, completing the winding of the glass fiber end onto the surface of the bolt sleeve. Then the wire clamping and winding clamp 24 releases the glass fiber, and the clamp extension drive drives the wire clamping and winding clamp 24 to retract and reset.

[0072] (8) The rotary drive 28 drives the fixed end positioning sleeve 27 to accelerate rotation, while the translation drive drives the wire feeding component to accelerate the reciprocating motion along the translation track 31, so that the glass fiber is evenly wrapped around the entire surface of the wind turbine blade bolt sleeve 7. After the wrapping is completed, the translation wire feeding component 3 stops at a position close to the knotting component 4, and the rotation of the fixed end positioning sleeve 27 is paused.

[0073] (9) The strut extension drive 29 drives the knotted strut 210 to extend between the fiberglass and the wind turbine blade bolt sleeve 7. The rotation drive 28 rotates slowly again to wrap the fiberglass around the knotted strut 210 to form a knotted loop. Then the rotation drive 28 stops rotating.

[0074] (10) The clamp of the knotting component 4 extends into the knotting ring to clamp the glass fiber filament. Then the support rod extension drive 29 drives the knotting support rod 210 to reset and retract. The knotting support rod 210 disengages from the knotting ring, and the clamp of the knotting component 4 retracts. The part of the glass fiber filament that is clamped is pulled out of the knotting ring. The rotation drive 28 rotates slowly again to compress the glass fiber pulled out of the knotting ring to form a knot. The wire feeding drive 32 of the translational wire feeding component 3 drives the wire feeding clamp 33 to extend and tighten the knot to complete the knotting. Repeat the above actions to knot multiple times to ensure that the glass fiber filament does not loosen.

[0075] (11) The cutting component 5 drives the cutting blade 54 to cut the wire. After the cutting is completed, the cutting component 5 is reset.

[0076] Based on the above embodiments, in another embodiment of the present invention, before step (5), a step of using a color difference sensor 310 to perform quality inspection on the sandblasting of the wind turbine blade bolt sleeve 7 is included: during the rotation of the wind turbine blade bolt sleeve 7, the translation wire feeding assembly 3 drives the color difference sensor 310 to move back and forth to perform precise inspection on the surface of the wind turbine blade bolt sleeve 7. If no quality problem is detected in the sandblasting of the wind turbine blade bolt sleeve 7, then step (6) is performed. If a quality problem is detected in the sandblasting of the wind turbine blade bolt sleeve 7, then the wind turbine blade bolt sleeve 7 is removed and step (1) is performed. After step (11), a step of using a laser ranging sensor 311 to detect the winding thickness of the wind turbine blade bolt sleeve is included: the translation wire feeding assembly 4 drives the laser measuring sensor 311 to move back and forth to measure and inspect the winding thickness of the wind turbine blade bolt sleeve 7 after winding, to ensure that the uniformity and thickness of the winding meet the process standards, and to store the measurement data to generate a production report.

[0077] Compared to existing technologies, this invention uses a lifting support assembly 1 to transport the wind turbine blade bolt sleeve 7 to a predetermined position, then uses a tightening mechanism to tighten it, and a translational wire feeding assembly 3 to feed glass fiber filaments to the vicinity of the bolt sleeve surface. The process of wire drawing, winding, knotting, and cutting is then automatically completed. This invention achieves high consistency and stable quality in bolt sleeve winding, realizing automation of bolt sleeve winding in the wind power industry and solving the problems of low efficiency, unstable quality, and high cost associated with manual winding in existing technologies.

[0078] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
