Description

Technical Field

[0001] This invention relates to the field of wind turbine blade manufacturing, specifically to a wind turbine blade pre-embedded screw sleeve sandblasting and yarn wrapping system, an automatic yarn wrapping device, and a yarn wrapping method. Background Technology

[0002] The embedded bolt sleeves of wind turbine blades serve as the connecting parts between the blades and the flange bolts of the wind turbine. The surface needs to be sandblasted first to improve the surface roughness and the reliability of fiberglass adhesion. Then, fiberglass yarn is wound around them to enhance the connection strength after injection and curing.

[0003] In the existing technology, the process of sandblasting and winding yarn for the pre-embedded threaded sleeve of wind turbine blades is mainly carried out by manually placing the pre-embedded threaded sleeve into the sandblasting machine. After the sandblasting operation is completed, the sleeve is placed on a pallet and transported to the yarn winding station. The pre-embedded threaded sleeve is then fixed on the semi-automatic yarn winding machine by manual means, and the yarn is knotted manually. After the yarn is wound by rotating the pre-embedded threaded sleeve, the tail yarn is cut off and knotted manually. The pre-embedded threaded sleeve is then removed and placed on a pallet for transport.

[0004] The above methods have the following drawbacks: (1) High labor intensity. The operation requires two operators to repeatedly move the pre-embedded screw sleeves. The number of screw sleeves is large and the weight is large, making the moving process laborious; (2) Low efficiency. After the sandblasting operation is completed, the screw sleeves need to be placed on a pallet and transported to the yarn winding station by forklift. The yarn winding process cannot be separated from manual operation; (3) Poor working environment. The noise of the sandblasting machine has a great impact on the operators and the environment. The dust generated during the sandblasting process causes pollution and harm to the operators and the environment. Summary of the Invention

[0005] In view of the existing processing methods for pre-embedded threaded sleeves of wind turbine blades, which are characterized by high labor intensity, low production efficiency, and poor working environment, this invention provides a sandblasting and yarn-winding system and an automatic yarn-winding device for pre-embedded threaded sleeves of wind turbine blades. This system can realize the automated production of pre-embedded threaded sleeves, eliminate the need for operators to manually wind and knot the yarn and carry the threaded sleeves, reduce labor intensity, improve production efficiency, and avoid the harm to personnel caused by the working environment.

[0006] The objective of this invention and the technical problem it solves are achieved by the following technical solution. A wind turbine blade pre-embedded threaded sleeve winding device according to this invention includes a frame platform, on which are provided: a tail support and a root support, coaxially spaced apart, for clamping the pre-embedded threaded sleeve and driving the pre-embedded threaded sleeve to rotate; a support base for placing the pre-embedded threaded sleeve, and moving upward to deliver the pre-embedded threaded sleeve to a position coaxial with the tail support and root support, or moving downward to avoid the pre-embedded threaded sleeve clamped between the tail support and root support; and a wire-laying mechanism, initially located on one side of the root support, capable of reciprocating along one side of the axial direction of the tail support and root support, having the function of... The device includes a wire feeding reel and wire shears for cutting the wire; a yarn clamp located on one side of the root support and capable of reciprocating along a linear guide; a movable disc located at the root support, capable of axial movement and circumferential rotation along the root support, and having a first position close to the pre-embedded threaded sleeve and a second position away from the pre-embedded threaded sleeve within its travel stroke; at least one column and a clamp spaced apart on its end face facing the pre-embedded threaded sleeve, and the clamp having the first and second positions when the movable disc rotates; in the initial state, both the movable disc and the clamp are in the first position, and the clamp holds the wire feeding reel. At the end of the yarn feed, as the feed wheel begins to feed the yarn and moves towards the tail support, the pre-embedded threaded sleeve rotates. Simultaneously, the moving disc drives the clamp to rotate from the first position to the second position, causing the yarn to wind around the pre-embedded threaded sleeve at a set tension. The feed wheel then moves towards the root support, pressing the new yarn against the yarn between the pre-embedded threaded sleeve and the clamp. The clamp then releases the yarn and returns to the first position. When the final winding cycle is completed, as the feed wheel moves to a set position away from the front clamping surface of the root support, the moving disc rotates, causing the yarn at the feed wheel end to wind around at least two posts or one post. When the yarn clamp is in the first position, the yarn clamp extends forward, allowing it to pass through the yarn between the two posts or between the posts and the clamp, and to hold the yarn at the end of the pay-off wheel. When the yarn clamp retracts, the held yarn passes through the inside of the yarn between the two posts or between the posts and the clamp. When the moving disc moves to the second position, the yarn between the two posts or between the posts and the clamp falls off and drapes over the yarn between the yarn clamp and the pay-off wheel. When the moving disc returns to the first position, the clamp can hold the fallen yarn and the yarn between the pay-off wheel. At this point, the wire cutter opens and can cut the yarn between the clamp and the yarn clamp.

[0007] The objectives of this invention and the technical problems it addresses can be further achieved by the following technical measures.

[0008] The aforementioned wind turbine blade pre-embedded threaded sleeve winding device also includes a yarn clamp, a movable disc, and a column and clamp fixed on the movable disc on the tail support side, so that the pre-embedded threaded sleeve can end the winding at either end.

[0009] The aforementioned wind turbine blade pre-embedded threaded sleeve winding device also includes a detection component on the support base for detecting whether the winding of the pre-embedded threaded sleeve is qualified.

[0010] In the aforementioned wind turbine blade pre-embedded threaded sleeve winding device, the tail support and the root support can clamp and release the pre-embedded threaded sleeve by relative movement along the axial direction.

[0011] The aforementioned wind turbine blade pre-embedded threaded sleeve winding device, wherein the tail support and / or root support can also adapt to pre-embedded threaded sleeves of different lengths by moving along the axial direction.

[0012] In the aforementioned wind turbine blade pre-embedded threaded sleeve winding device, a fixed plate is also provided on the side of the movable disk away from the pre-embedded threaded sleeve. The fixed plate is axially fixed relative to the pre-embedded threaded sleeve and can drive the movable disk to rotate. The movable disk can move axially relative to the fixed plate under the drive of the movable drive device.

[0013] The objective of this invention and the solution to its technical problem are also achieved by the following technical solution.

[0014] The objectives of this invention and the technical problems it addresses can be further achieved by the following technical measures.

[0015] The aforementioned wind turbine blade pre-embedded screw sleeve sandblasting and yarn wrapping system has at least two loading platforms and a first conveying device to ensure that at least one loading platform at the transfer station contains the pre-embedded screw sleeve during operation.

[0016] The aforementioned wind turbine blade pre-embedded threaded sleeve sandblasting and yarn wrapping system also includes a detection component in the yarn wrapping device, and a subsequent transfer device delivers the qualified pre-embedded threaded sleeve to the unloading platform.

[0017] The objective of this invention and the technical problem it solves are achieved by the following technical solution. An automatic yarn winding method using the aforementioned yarn winding device, according to this invention, includes the following steps: 1) The pre-embedded threaded sleeve, after sandblasting, is placed on the support seat of the yarn winding device. The support seat raises the pre-embedded threaded sleeve to a position coaxial with the tail support and the root support. After the tail support and the root support clamp the pre-embedded threaded sleeve, the support seat descends; 2) The yarn feeding structure drives the yarn feeding wheel to move away from the clamping direction of the free end of the yarn and feeds the yarn. Simultaneously, the pre-embedded threaded sleeve rotates, and the clamping direction of the free end of the yarn... 1) The clamps rotate from the first position to the second position, tightening the yarn wound on the pre-embedded threaded sleeve; 2) The yarn feeding mechanism moves to the set position and then rotates back, so that the new yarn covers the yarn wound on the pre-embedded threaded sleeve first, then the clamps release the yarn and return to the first position; 3) The yarn feeding mechanism moves in the opposite direction again and rotates back after completing one round of yarn feeding, repeating the yarn feeding process until the last round of yarn feeding. When the yarn feeding wheel reaches the set position, the moving disc rotates a set circle, causing its extended column to pull the end of the yarn feeding wheel. 5) The yarn at the end of the pay-off wheel detaches from the column and wraps around the pre-embedded stud 1-3 times before the pre-embedded stud stops rotating; 6) The yarn clamp extends forward through the inside of the yarn between the two columns or between the column and the clamp, and after clamping the yarn at the end of the pay-off wheel, it retracts to the front end to detach the yarn wrapped on the column; 7) The moving disc moves to the second position, causing the yarn on the column to fall off, and the fallen yarn draped over the yarn between the yarn clamp and the pay-off wheel; 8) The moving disc returns to the first position and then opens the clamps to clamp the yarn between the yarn reel and the loose yarn; 9) The thread cutter on the yarn feeding mechanism opens and cuts the yarn between the clamps and the yarn clamps; 10) The yarn clamps retract and pull the cut yarn end out from under the loose yarn; 11) The pre-embedded thread sleeve rotates to tighten the loose yarn; 12) The yarn clamps release the yarn and return to the initial position, and the support rises to support the pre-embedded thread sleeve; 13) The tail support and root support release the pre-embedded thread sleeve and return to the initial position.

[0037] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation, structure, features, and effects of the wind turbine blade pre-embedded screw sleeve sandblasting and yarn wrapping system proposed according to the present invention.

[0038] Please see Figure 1-4 This is a schematic diagram of the various parts of the wind turbine blade pre-embedded threaded sleeve sandblasting and yarn wrapping system of the present invention. The system includes a first conveying device 100, a loading platform 200, a sandblasting device 300, a transfer device 400, a detection device 500, a front transfer device 600, a yarn wrapping device 700, a rear transfer device 800, an unloading platform 900, and a second conveying device 1000. The loading platform 200 is placed above the first conveying device 100 and is used to place the pre-embedded threaded sleeve. The first conveying device 100 is used to transport the loading platform 200 to the transfer station. That is, the loading platform 200 and the first conveying device 100 cooperate to realize the transportation of the pre-embedded threaded sleeve. The sandblasting device 300 is used for automatic sandblasting of the pre-embedded threaded sleeve; the detection device 500 is used to detect the sandblasting quality of the pre-embedded threaded sleeve. The transfer device 400 is used to transport the pre-embedded threaded sleeves on the loading platform 200 at the transfer station to the sandblasting device 300, and to transport the pre-embedded threaded sleeves after sandblasting in the sandblasting device 300 to the testing device 500 for testing. In this embodiment, the transfer device 400 is a robotic arm structure, which realizes the transfer of the pre-embedded threaded sleeves between the loading platform 200, the sandblasting device 300, and the testing device 500 through the robotic arm.

[0039] The front transfer device 600 is located between the detection device 500 and the yarn winding device 700, and is used to transport the pre-embedded threaded sleeves that have passed the inspection by the detection device 500 to the yarn winding device 700; the rear transfer device 800 is located between the yarn winding device 700 and the unloading platform 900, and is used to transport the pre-embedded threaded sleeves that have been wound by the yarn winding device 700 to the unloading platform; the unloading platform 900 is located above the second conveying device 1000, and delivers the pre-embedded threaded sleeves to the second conveying device 1000. In this embodiment, both the front loading device 600 and the rear transfer device 800 are robotic arm structures.

[0040] The yarn winding device 700 includes a frame platform 701, on which are provided a tail support 706, a support base 707, a root support 709, a yarn feeding mechanism 715, and a yarn clamp 702. The tail support 706 and the root support 709 are coaxially and indirectly arranged to clamp a pre-embedded threaded sleeve 703 and drive the pre-embedded threaded sleeve 703 to rotate under the action of a driving device. The support base 707 supports the pre-embedded threaded sleeve 703 and can move the pre-embedded threaded sleeve 703 to a position coaxial with the tail support 706 and the root support 709 by moving it up and down, facilitating the clamping and rotation of the pre-embedded threaded sleeve 703. After the tail support 706 and the root support 709 clamp the pre-embedded threaded sleeve 703, the support base 707 moves downward under the drive of the driving device to avoid the pre-embedded threaded sleeve 703, ensuring sufficient space below the pre-embedded threaded sleeve 703 for its rotation and yarn winding. In this embodiment, the support base 707 has two protruding support portions spaced apart along the axial direction of the pre-embedded threaded sleeve. Each support portion has a groove, preferably a V-shaped groove. The bottom of the support base 707 is also provided with a detection component 7071 for collecting data from the pre-embedded threaded sleeve supported thereon and detecting whether its yarn winding is qualified.

[0041] The tail support 706 and the root support 709 can move relative to each other and away from each other along the axial direction to clamp the pre-embedded threaded sleeve 703 to be wound with yarn and to release the pre-embedded threaded sleeve 703 after the yarn has been wound. Furthermore, the distance between them can be adjusted to accommodate the clamping requirements of pre-embedded threaded sleeves 703 of different lengths. In this embodiment, both the tail support 706 and the root support 709 can move along their axial direction. When it is necessary to clamp the pre-embedded threaded sleeve 703, the tail support 706 and the root support 709 move relative to each other, clamping both ends of the pre-embedded threaded sleeve 703. When it is necessary to release the pre-embedded threaded sleeve after the yarn has been wound, the tail support 706 and the root support 709 move away from each other. In this embodiment, the tail support 706 and the root support 709 are respectively provided with guide posts 717 for inserting into one end and the other end of the cavity of the pre-embedded threaded sleeve 703 and for clearance fitting with the inner wall of the pre-embedded threaded sleeve 703. The tail support 706 and the root support 709 are also provided with clamping surfaces for clamping with the end faces of the pre-embedded threaded sleeve. The guide posts 717 are located on the clamping surfaces, and the pre-embedded threaded sleeve can rotate together with the clamping surfaces under the drive of the driving device. The clamping surface on the tail support 706 is the first clamping surface 7061, and the clamping surface on the root support is the second clamping surface 7062. Preferably, the tail support 706 is matched with a drive motor and a synchronous belt 716, and the first clamping surface 7061 on the tail support 706, the pre-embedded threaded sleeve, and the second clamping surface 7062 on the root support 709 are rotated together by the drive motor and the synchronous belt 716.

[0042] The yarn feeding mechanism 715 is located on one side of the support base 707 and can reciprocate along the axial direction of the clamped embedded threaded sleeve 703, causing the yarn to reciprocate and wind around the embedded threaded sleeve 703 to complete the yarn winding work. The yarn feeding mechanism 715 includes a yarn feeding wheel 704 and a yarn shear 705. The yarn feeding wheel 704 is used to feed the yarn, allowing it to wind around the embedded threaded sleeve 703 as the yarn feeding mechanism 715 reciprocates on one side of the embedded threaded sleeve. The yarn shear 705 is used to cut the yarn.

[0043] The tail support 706 and / or the root support 709 are also provided with a yarn clamp 702 on one side. The yarn clamp 702 can reciprocate along the linear guide rail under the drive of the drive device, so as to clamp the yarn and pull it backward.

[0044] A movable disk 711, capable of moving axially back and forth and independently rotating relative to the pre-embedded threaded sleeve 703, is also provided on the tail support and / or root support 709 of the yarn clamp 702 on one side. The movable disk 711 is located behind the clamping surface, i.e., away from the end of the pre-embedded threaded sleeve 703. The movable disk 711 has a first position and a second position within its axial travel. A clamp 708 and a column 710 are fixedly provided on the end face of the movable disk 711 facing the pre-embedded threaded sleeve 703, and the clamp 708 and column 710 on the same movable disk 711 are located on different diameters of the movable disk 711, i.e., their positions in the circumferential direction are different.

[0045] In this embodiment of the invention, a yarn clamp 702 and a movable disk 711 are provided only on one side of the root support 709. The positional relationship and operation process of the yarn clamp 702, the movable disk 711 located on the side of the yarn clamp 702, the clamps 708 on the movable disk 711, and the column 710 are described in detail using this embodiment as an example. The arrangement and operation process of the yarn clamp 702, movable disk 711, clamps 708, and column 710 on the tail support side are the same as in this embodiment and will not be described in detail again.

[0046] The clamp 708 clamps the free end of the yarn when the yarn feeding mechanism 715 starts feeding. After the yarn feeding mechanism 715 winds a set length of yarn onto the pre-embedded threaded sleeve, it rotates with the moving disk 711 under the drive of the drive device, tightening the yarn on the pre-embedded threaded sleeve. Once the yarn is tightened to a set state and the free end of the yarn is pressed against the pre-embedded threaded sleeve by new yarn, the clamp releases the free end of the yarn, completing the pressing process. The position where the clamp 708 begins to clamp the free end of the yarn is defined as the first position, and the position when the yarn is tightened to the set state is defined as the second position. After completing the pressing process, the clamp 708 returns from the second position to the first position.

[0047] When the pay-off mechanism 715 moves to the root base 709 side, the movable disk 711 in the first position rotates along the direction of the pre-embedded screw sleeve, causing the clamp 708 to rotate from the first position to the second position, and enabling the thread released by the pay-off wheel to wrap around the clamp 708 and the column 710 on it. When the clamp 708 returns to the first position, the yarn clamp 702 located on one side of the clamp 708 can move forward along the linear guide rail, pass through the inner side of the yarn wrapped between the clamp 708 and the column 710, and clamp the yarn on the side of the pay-off wheel 704. After clamping the yarn, it moves backward along a straight line and disengages from the clamp 708 and the column 710. At this time, the movable disc 711 moves away from the pre-embedded threaded sleeve to the second position, and the yarn on the clamp 708 and the column 710 falls off. When the movable disc 711 is moved back to the pre-embedded threaded sleeve to the first position, the clamp 708 can clamp the yarn feeding wheel 704 and the yarn that has fallen off the clamp 708 and the column 710. At this time, when the thread cutter 705 opens, it can cut the yarn between the clamp 708 and the yarn clamp 702. If the yarn clamp 702 continues to move backward, the fallen yarn can be tightened, and the knot at the end of the yarn wrapped on the pre-embedded threaded sleeve 703 is completed.

[0048] In other embodiments of the present invention, the column 710 is provided with at least two circumferentially distributed movable disks 711 located in the first position. When the movable disk 711 rotates, the yarn released by the yarn release wheel 704 of the yarn release mechanism 715 moved to the root base 709 side is wound around the outside of the column 710. At this time, the clamp 708 can be wound with yarn or not. The yarn clamp 702 pulls the yarn on the side of the yarn release wheel 704 from the inside of the yarn wound on the column 710 between two of the columns. When the movable disk 711 moves to the second position, the yarn on the two columns 710 falls off. When the movable disk is moved to the first position again, the clamp 708 opens to clamp the fallen yarn and the yarn between the yarn release wheel. Then, the yarn between the clamps 708 and 702 is cut by the wire cutter 705. The yarn clamp 702 is then moved backward to tighten the detached yarn and complete the knotting of the yarn tail wrapped around the pre-embedded screw sleeve 703.

[0049] When the yarn clamp and moving disc are provided only on one side of the tail support 706 or the root support 709, the yarn winding device 700 can only wind an even number of yarn turns. When the yarn clamp and moving disc are provided on both the tail support 706 and the root support 709, the winding of any number of yarn turns can be achieved.

[0050] In this embodiment of the invention, a fixed disk 712 is provided on the side of the movable disk 711 away from the pre-embedded threaded sleeve 703. This fixed disk 712 can rotate with the movable disk 711 but is axially fixed relative to the pre-embedded threaded sleeve 703. A moving drive mechanism 713 is provided on the frame platform 701 for driving the movable disk 711 to slide axially relative to the fixed disk 712. Preferably, a control disk 718 for controlling the opening and closing of the clamp 708 is also provided between the movable disk 711 and the fixed disk 712. This control disk 718 can move axially relative to the fixed disk 712 and the movable disk 711 under the drive of the drive mechanism fixed on the fixed disk 712, causing the clamp 708 fixed on the movable disk 711 to open or close. In this embodiment, the fixed disk 712 and the drive disk 718 are connected by a connecting post 714, so that when the fixed disk 712 rotates, it can drive the drive disk 718 to rotate, and simultaneously, the drive disk 718 drives the movable disk 712 to rotate.

[0051] The following embodiments of the present invention provide a detailed description of the specific usage method of the wind turbine blade pre-embedded screw sleeve sandblasting and yarn wrapping system.

[0052] In this embodiment, there are two loading platforms 200 and two first conveying devices 100. Each first conveying device 100 corresponds to one loading platform 200. Each loading platform 200 is equipped with several pre-embedded screw sleeves. In use, the two sets of feeding devices composed of loading platforms 200 and first conveying devices 100 work alternately. When all the pre-embedded screw sleeves on the loading platform 200 of one set of feeding devices are removed, the transfer device grabs the pre-embedded bolts in the loading platform of the other feeding device. The empty assembly platform is sent back to the loading by the first conveying device and sent back to the transfer station after the loading is completed.

[0053] The transfer device 400 picks up the pre-embedded threaded sleeves from the loading platform 200 at the transfer station and transports them to the sandblasting device 300. The silo door closes automatically, and the sandblasting device 300 performs automatic sandblasting. After the sandblasting device 300 completes sandblasting, the silo door opens automatically, the transfer device 400 picks up the sandblasted pre-embedded threaded sleeves from the sandblasting device 300, rotates them 90 degrees, and transfers them to the testing device 500. Then, the transfer device 400 picks up the pre-embedded threaded sleeves from the loading platform 200 at the transfer station again and transports them to the sandblasting device 300 for sandblasting. Finally, the sandblasted pre-embedded threaded sleeves are sent to the testing device, and the above process is repeated continuously.

[0054] The front transfer device 600 picks up the pre-embedded threaded sleeves that have passed the inspection by the testing device 500 and places them on the winding device 700, which automatically completes the winding operation. In this embodiment, the system has two winding devices 700, which can automatically wind two pre-embedded threaded sleeves simultaneously. However, the number of winding devices is not limited to this and can be set as needed. The rear transfer device 800 picks up the pre-embedded threaded sleeves that have completed the winding operation and passed the inspection, and transfers them to the unloading platform 900, from where they are conveyed to the transfer station via the second conveying device 1000.

[0055] In this process, the pre-embedded threaded sleeve grasped by the front transfer device 600 is placed on the support seat 707 of the yarn winding device 700. After the detection component 7071 completes the initial detection data acquisition of the pre-embedded threaded sleeve, the support seat 707 lifts the pre-embedded threaded sleeve to a position coaxial with the tail support 706 and the root support 709. The tail support 706 and the root support 709 move relative to each other to clamp the pre-embedded threaded sleeve. The support seat 707 then descends, leaving sufficient space for the pre-embedded threaded sleeve to rotate and wind yarn.

[0056] At this point, both the clamp 708 and the moving disc 711 are in the first position. The free end of the yarn on the yarn feeding mechanism 704, located on one side of the root support, is clamped by the clamp 708. The yarn feeding wheel 704 moves towards the tail support 706 with the yarn feeding device and feeds the yarn. At the same time, the drive motor and synchronous belt 716 at the tail support 706 drive the embedded thread sleeve to rotate. The clamp 708 also rotates from the first position to the second position under the action of the drive mechanism, and the clamp 708 and the embedded thread sleeve rotate in opposite directions, so that the yarn on the embedded thread sleeve is locked in the groove of the embedded thread sleeve under the pull of the clamp 708 to the set tightness. After the clamp 708 rotates to the second position, the yarn feeding mechanism, which has moved a set distance towards the tail support, turns back towards the root support. During this process, the yarn feeding wheel 704 feeds the yarn, the embedded thread sleeve rotates and winds the yarn, and the moving disc 711 remains stationary until the new yarn covers the original yarn on the embedded thread sleeve, completing the yarn pressing. In this embodiment, the yarn feeding mechanism moves towards the tail support until one round of yarn winding is completed or until the yarn feeding wheel is 10cm away from the clamping surface of the root support 709, then folds back to press the yarn. During yarn pressing, the yarn feeding mechanism moves towards the root support until the yarn feeding wheel is 4-5mm away from the clamping surface of the root support 706, then stops.

[0057] After the yarn pressing is completed, the pre-embedded threaded sleeve continues to rotate, and the pay-off wheel 704 moves from the root support 709 to the tail support 706 to complete one round of yarn winding. Then, the pay-off wheel moves from the tail support to the root support again to complete another round of yarn winding. When the pre-embedded threaded sleeve performs the last round of yarn winding (in this embodiment, it is an even number of times), the pay-off wheel 704 returns to the set position on the root support 709 side, the moving disk 711 rotates, and the column 710 located on the moving disk 711 rotates 1-3 times with the moving disk. At the same time, the yarn released by the pay-off wheel is pulled by the column 710 and wound around the column and the back of the clamp 708. At this time, the clamp 708 returns to the first position with the moving disk. Except for the last round of yarn winding, the distance between the pay-off wheel and the nearest clamping surface is 4-5mm when receiving yarn for each round of yarn winding. During the last round of yarn winding, the pay-off wheel starts rotating at a position 3-5cm away from the root support, and the knotting work begins.

[0058] As the pay-off wheel 704 moves toward the root support, when the moving disc 711 stops rotating, the yarn at the end of the pay-off wheel 704 detaches from the column 710 and rewound onto the pre-embedded threaded sleeve. After winding 1-2 turns, both the pay-off wheel and the pre-embedded threaded sleeve stop moving.

[0059] After completing the above actions, the yarn clamp 702 extends forward, passes through the inside of the yarn wound between the column 710 and the clamp 708, and retracts after clamping the yarn between the pre-embedded threaded sleeve and the yarn reel 704, so that the yarn on the yarn clamp 702 passes through the yarn wound on the column 710 and the clamp 708 and is located outside the wound yarn. Then, the movable disk 711 moves to the second position, causing the yarn on the column 710 and the clamp 708 to fall off and drape over the yarn between the yarn clamp 702 and the pay-off reel 704.

[0060] Move the moving disc again to return it to the first position. The clamp 708 opens and clamps the yarn between the overlapping yarn (the yarn that has fallen off the column 710 and the clamp 708) and the pay-off reel 704. The thread cutter opens 705 and cuts the yarn between the clamp 708 and the yarn clamp 702. At this time, the free end of the yarn on the pay-off reel 704 is held by the clamp 708.

[0061] Then, drive the yarn clamp 702 to move backward, pulling the clamped yarn and pulling out the yarn end, so that the overlapping yarn presses down on the yarn end. Next, drive the pre-embedded threaded sleeve to rotate slowly two revolutions, tightening the yarn and pressing the overlapping yarn end. Finally, drive the yarn clamp 702 to release the yarn and return to the initial position, completing the automatic yarn winding operation.

[0062] After the yarn winding is completed, the support seat 707 rises, supports the pre-embedded threaded sleeve and inspects the pre-embedded threaded sleeve. The tail support 706 and the root support 709 move away from each other and return to their initial positions, and the pre-embedded threaded sleeve is released.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

Claims

1. A device for winding yarn around a pre-embedded threaded sleeve on a wind turbine blade, characterized in that, Includes a rack platform, which is equipped with: The tail support and the root support are coaxially spaced to clamp the embedded threaded sleeve and drive the embedded threaded sleeve to rotate. The support base is used to place the pre-embedded threaded sleeve, and moves upward to send the pre-embedded threaded sleeve to a position coaxial with the tail support and the root support, or moves downward to avoid the pre-embedded threaded sleeve sandwiched between the tail support and the root support. The wire feeding mechanism, initially located on one side of the root support, can reciprocate along one side of the pre-embedded thread sleeve, and has a wire feeding wheel for feeding and a wire shear for cutting the wire. The yarn clamp is located on the root support side and can move back and forth. The movable disc is capable of moving axially and rotating circumferentially along the root support, and has a first position close to the pre-embedded threaded sleeve and a second position far away from the pre-embedded threaded sleeve within its moving stroke; The movable disc has at least one column and a clamp spaced apart on the end face facing the pre-embedded threaded sleeve, and the clamp has a first position and a second position when the movable disc rotates. In the initial state, both the moving disc and the clamp are in the first position, and the clamp holds the end of the yarn being released from the pay-off wheel. When the pay-off wheel starts to release the yarn and moves towards the tail support, the pre-embedded thread sleeve rotates. At the same time, the moving disc drives the clamp to rotate from the first position to the second position, so that the yarn is wound around the pre-embedded thread sleeve with a set tension. After the pay-off wheel moves towards the root support and the new yarn presses against the yarn between the pre-embedded thread sleeve and the clamp, the clamp releases the yarn it is holding and returns to the first position. When the yarn winding is completed for the last time, the pay-off wheel moves to the set position at the front clamping surface of the root support. The moving disc rotates, so that the yarn at the end of the pay-off wheel is wound around at least two posts or one post and the clamp. At this time, the yarn clamp extends forward, can pass through the yarn between the two posts or between the post and the clamp and clamp the yarn at the end of the pay-off wheel. The yarn clamp retracts so that the clamped yarn passes through the inside of the yarn between the two posts or between the post and the clamp. When the moving disc moves to the second position, the yarn between the two columns or between the column and the clamp falls off and drapes onto the yarn between the yarn clamp and the feed wheel. When the moving disc returns to the first position, the clamp can hold the fallen yarn between the yarn and the feed wheel. At this time, the wire cutter opens and can cut the yarn between the clamp and the yarn clamp.

2. The wind turbine blade pre-embedded threaded sleeve winding device according to claim 1, characterized in that, The tail support side is also equipped with yarn clamps, a movable disc, and a column and clamps fixed on the movable disc, so that the pre-embedded threaded sleeve can end the yarn winding at either end.

10. An automatic yarn winding method using the yarn winding device according to any one of claims 1-6, characterized in that, Includes the following steps: 1) The pre-embedded threaded sleeve after sandblasting is placed on the support seat of the yarn winding device. The support seat lifts the pre-embedded threaded sleeve to a position coaxial with the tail support and the root support. After the tail support and the root support move relative to each other to clamp the pre-embedded threaded sleeve, the support seat descends. 2) The feeding structure drives the feeding wheel to move away from the clamps holding the free end of the yarn and feeds the yarn. At the same time, the pre-embedded screw sleeve rotates, and the clamps holding the free end of the yarn rotate from the first position to the second position, so that the yarn wrapped on the pre-embedded screw sleeve is tightened. 3) After the yarn feeding mechanism moves to the set position, it rotates so that the new yarn covers the yarn that was first wound on the pre-embedded screw sleeve. Then the clamps release the yarn and return to the first position. 4) The yarn feeding mechanism moves in the opposite direction again and rotates after completing one winding cycle. The winding process is repeated until the last winding cycle is performed. When the yarn feeding wheel reaches the set position, the moving disk rotates the set circle, causing the extended column to pull the yarn at the end of the yarn feeding wheel and make the yarn wind around at least two columns or the back of the columns and clamps. 5) The yarn at the end of the pay-off wheel detaches from the column and wraps around the pre-embedded stud 1-3 times before the pre-embedded screw sleeve stops rotating; 6) The yarn clamp extends forward, passes through the inside of the yarn between the two posts or between the posts and the clamp, and after clamping the yarn at the end of the feed wheel, it retracts to the front end to detach from the posts and wrap the yarn. 7) Move the movable disc to the second position to cause the yarn on the column to fall off, and the fallen yarn will be placed on the yarn between the yarn clamp and the feed wheel; 8) Move the disc back to the first position, then open the clamps to grip the yarn between the yarn reel and the loose yarn; 9) The wire shears on the wire feeding mechanism open to cut the yarn between the clamps and the yarn clamps; 10) Retract the yarn clamps to pull the cut yarn end out from under the detached yarn; 11) Rotating the pre-embedded threaded sleeve tightens the loosened yarn; 12) The yarn clamps loosen the yarn and return to their initial position, and the support base rises to support the pre-embedded threaded sleeve; 13) Loosen the pre-embedded bolt sleeves of the tail support and root support and return them to their initial positions.
