Description

Technical Field

[0001] This utility model belongs to the field of wind turbine blade laying technology, specifically relating to a laying mechanism of an automatic wind turbine blade laying device. Background Technology

[0002] Blades are the most basic and critical component of wind turbines. Their good design, reliable quality, and superior performance are decisive factors in ensuring the normal and stable operation of the unit. In wind turbines, blade design directly affects the wind energy conversion efficiency and its annual power generation, making it a crucial link in wind energy utilization. There are two main processes used for large wind turbine blades: open-mold manual layup and closed-mold vacuum impregnation. In the open-mold manual layup process, the film roll is mainly laid manually. This method has the following drawbacks: due to the large length of large blades, workers need to run long distances while carrying heavy loads during the layup process, resulting in high labor intensity and fatigue. Consequently, the quality of the fabric laying is prone to poor, leading to rework. In other words, the current fabric laying operation requires high labor intensity from workers and is not efficient enough. Utility Model Content

[0040] An automatic wind turbine blade deployment method includes the following steps:

[0041] Step S1: Scan and locate the wind turbine blade, and generate several fabric laying paths according to the position of the wind turbine blade. Push the fabric roll 1700 to one end of the wind turbine blade through the fabric roll 1700 trolley. The fabric pick and place unit automatically picks up the fabric roll 1700 and moves the fabric roll 1700 into place.

[0042] Step S2: Move the fabric pulling unit 1500 to the right side, release the fabric roll 1700 to the set length, then move the fabric pulling unit 1500 back to the left side, and drag the released fabric roll 1700 under the fabric suction unit 1600. The fabric pulling unit 1500 moves up and down in coordination with the fabric suction unit 1600 to flatten the fabric roll 1700.

[0043] Step S3: The automatic wind turbine blade laying device is moved to the front end of a laying path by hoisting, and the automatic wind turbine blade laying device is rotated by the flipping mechanism 1100 so that the automatic wind turbine blade laying device is close to the laying path and moves along the laying path.

[0044] Step S4: The glue spraying mechanism 3000 first sprays gel coat onto the laying path, the pole cloth unit 2200 then presses down on the cloth roll 1700, and the pressing unit 2100 finally presses down to press the cloth roll 1700 and the wind turbine blade together. After the automatic wind turbine blade laying device moves a set distance along the laying path, the flat cloth unit 2400 holds the cloth roll 1700 and blows it flat. The cutting unit 2300 then cuts the cloth roll 1700 and continues to drive the glue spraying mechanism 3000, the pole cloth unit 2200 and the pressing unit 2100 to complete the laying path.

[0045] Step S5: Repeat step S2 until all laying paths are completed.

[0046] Working principle:

[0047] First, the wind turbine blades to be laid are placed in the processing area. A hoisting device (such as a truss structure) moves the automatic wind turbine blade laying device, scanning the entire wind turbine blade and locating its position (this can be achieved using the technical solution in the utility model with patent number CN116141701A). Several laying paths are generated based on the blade's position. Then, the fabric roll 1700 is pushed to one end of the wind turbine blade by the fabric roll 1700 trolley. The hoisting device moves the automatic wind turbine blade laying device above the fabric roll 1700 trolley. The first servo motor 1210 starts, driving the first lead screw 1230 to rotate. Through the cooperation of the first lead screw 1230 with the first and second threaded blocks, the first clamping assembly 1300 and the second clamping assembly 1400 move to both ends, providing space for the installation of the fabric roll 1700. The first servo cylinder 1350 drives the first mounting plate 1330 to move downward, and the second servo cylinder 1450 drives the second mounting plate 1430 to move downward, so that the first pneumatic chuck 1360 and the second pneumatic chuck 1460 move to both ends of the fabric roll 1700. Then, the first servo motor 1210 reverses the first lead screw 1230, so that the first pneumatic chuck 1360 and the second pneumatic chuck 1460 clamp the two ends of the fabric roll 1700. Then, the first mounting plate 1330 and the second mounting plate 1430 are moved upward into place.

[0048] The third servo cylinder 1510 drives the first air rod to move to the right, that is, drives the first fabric feeding push plate 1530 to move towards the fabric roll 1700. The first air cylinder 1520 pushes the first fabric feeding push plate 1530 downward. The front end of the first mounting plate 1330 is provided with a second servo motor 1370. The second servo motor 1370 drives the fabric roll 1700 to release a set length of fabric. The first cylinder drives the first fabric feeding push plate 1530 to move to the left. The first fabric feeding push plate 1530 drags the fabric roll 1700 towards the fabric suction unit 1600. The first flat fabric plate 1630 and the second flat fabric plate 1640 can flatten the fabric roll 1700, ensuring that the fabric suction unit 1600 can more stably suck up the fabric roll 1700. The first connection port 1611 is connected to the suction source (such as a vacuum pump), so that the first suction nozzle 1612 can suction the fabric roll 1700 under negative pressure.

[0049] The automatic wind turbine blade laying device is then moved to the left end of the corresponding laying path. The hoisting equipment moves the automatic wind turbine blade laying device into place, and the first drive motor 1140 can drive the first rotating shaft 1130 to rotate, so that the first mounting frame 1110 and the second mounting frame 1120 can rotate relative to each other. Since the first mounting frame 1110 is fixed on the hoisting equipment, the second mounting frame 1120 can be driven to rotate, that is, the first frame 1000 is driven to rotate, so that the cloth laying mechanism, the cloth pressing mechanism and the glue spraying mechanism 3000 can fit the laying path.

[0050] The hoisting equipment drives the first frame 1000 to move along the corresponding laying path. The fifth servo cylinder 3100 drives the second slide table 3110 to move back and forth. At the same time, the sixth servo cylinder 3200 drives the first pressure block 3210 to press the first pressure nozzle 3410. Then the first gel coat can 3400 sprays gel coat through the first spray nozzle 3310 toward the wind turbine blade. The hoisting equipment continuously moves the first frame 1000, and the fabric roll 1700 is unwound synchronously. The third cylinder 2210 drives the fifth support frame 2220 to move downward, so that the first rubber plate 2230 can abut against the fabric and pull the fabric. At the same time, the first fabric pulling brush 2240 can also abut against the fabric and pull the fabric. Through the first fabric pulling brush 2240 and the first rubber plate 2230, the fabric can be smoothed and fully contacted with the wind turbine blade mold cavity. Furthermore, the fourth cylinder 2250 can push the second fabric pulling brushes 2260 at both ends to move downward, which can ensure that the edge of the fabric can fully contact the edge of the laying path corresponding to the wind turbine blade mold cavity, ensuring the fabric pulling effect. Then, simultaneously, the second cylinder 2110 pushes the fourth support frame 2120 downward, causing the first pressing sheet 2130 to press against the wind turbine blade mold cavity. The first pressing sheet 2130 has an arc-shaped design and a certain degree of elasticity, which can better fit the wind turbine blade mold cavity. The first rubber pad 2140 can also play a buffering and fitting role, ensuring the effect of the fabric. Furthermore, another set of fabric units 2200 can be set at the left end of the second support frame 1540 to further press the fabric roll 1700 and the wind turbine blade mold cavity together. After the hoisting equipment moves the first frame 1000 a set distance along the corresponding fabric laying path, the first rotary motor 2410 drives the first rotating plate 2420 to rotate, causing the first rotating plate 2420 to flatten the fabric roll 1700. The first air-blowing knife 2430 blows air onto the first rotating plate 2420 and the fabric on it, flattening the fabric at the top of the first rotating plate 2420. Then, the fourth servo cylinder 2310 drives the first slide base 2320 to move back and forth. The second drive motor 2330 can drive the second lead screw 2350 to rotate, thereby driving the first knife holder 2340 to move up and down. The third drive motor 2370 drives the third conveyor wheel 2371 to rotate, which in turn drives the fourth conveyor wheel 2361 to rotate via the second conveyor belt, thereby driving the first knife bar 2360 to rotate, thus adjusting the direction of the first cutting knife 2362. The first knife holder 2340 descends, causing the first cutting knife 2362 to descend, thus cutting the fabric. Then, the first frame 1000 continues to move until the glue spraying mechanism 3000, the pole cloth unit 2200 and the pressing cloth unit 2100 have completely completed the corresponding laying path.

[0051] Finally, the wind turbine blades were laid out one by one according to each laying path, thus realizing the automatic laying of wind turbine blades.
