Description

Technical Field

[0001] This invention belongs to the field of wind turbine blade cutting technology, and specifically relates to a laser cutting device for wind turbine production. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It is a type of driven fluid machinery. Fan blades are generally made of metal. In the production of fan blades, laser cutting equipment is used to cut the fan blades into the required shape and size from the metal sheet.

[0003] A search revealed that in the prior art, Chinese Patent Publication No. CN219724960U, published on September 22, 2023, discloses a wind turbine blade cutting device. This device includes a laser cutting machine body with a laser cutting head mounted on top. A protective structure is fitted onto the laser cutting head, comprising a conical baffle, a mounting connecting ring, a mounting fixing ring, a push spring, and a mounting base ring. The mounting connecting ring is mounted on the upper end of the conical baffle, the push spring on the upper end of the mounting connecting ring, the mounting fixing ring on the upper end of the push spring, and the mounting base ring on the lower end of the conical baffle. Several anti-friction balls are symmetrically mounted on the mounting base ring, rotating on it.

[0019] The beneficial effects of this invention are:

[0020] 1. By controlling the movable plate, several sets of laser generators in a rectangular array are used to perform multi-area synchronous laser cutting on metal sheets. Several sets of mounting blocks are connected to each other by telescopic rods, and the vertical two-sided edges are connected by scaling linkages. By controlling the horizontal movement of two sets of sliding rods, the four sets of guide columns at the bottom of the two sets of sliding rods can move within four sets of limit grooves and drive the four sets of mounting blocks at the corners to move, thereby completing the scaling of the rectangular array of several sets of laser generators, and thus completing the cutting of wind turbine blades of different sizes. This improves the processing efficiency of the laser cutting equipment for wind turbine blades and increases the processing range of wind turbine blades.

[0021] 2. After the metal sheet is fed and fixed to a horizontal position by controlling the sheet limiting mechanism, the four sets of second electric slides drive the two sets of second leveling rollers to rotate above the metal sheet and abut against the top of the metal sheet. Then, the four sets of second lead screws are controlled to rotate. Under the threaded connection between the four sets of second lead screws and the four sets of second sliders, the two sets of first leveling rollers and the two sets of second leveling rollers abut against the two sides of the metal sheet and reciprocate in the horizontal direction, thereby leveling the metal sheet without affecting the automatic feeding of the metal sheet, thus improving the processing quality of the laser cutting equipment.

[0022] 3. By controlling the rotation of the placement plate and its contact with the ground, the rotation of the two sets of first lead screws is controlled. Under the threaded connection between the first lead screw and several sets of first sliders, the several sets of first sliders move horizontally and drive the partition plate from the storage slot to the outside through the corresponding connecting rod. Then, several sets of metal plates can be placed between the corresponding partition plates, so that the adjacent metal plates can be spaced accordingly. This allows the plate limiting mechanism to complete the automatic feeding work and improves the feeding efficiency of the fan blades of the laser cutting equipment.

[0023] 4. The slag and debris generated during the cutting of multiple sets of fan blades enter the collection tank after passing through the filters on the two sets of guide frames. Two sets of inclined baffles prevent the slag and debris from falling on the top of the conveyor belt. When the cutting is completed, several sets of cut fan blades will fall on top of the two sets of filters. Then, the two sets of guide frames are controlled to rotate into the collection tank, so that several sets of fan blades can slide onto the top of the conveyor belt for collection. This improves the slag and debris collection effect of the laser cutting equipment and increases the feeding efficiency of the fan blades.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention provides a laser cutting device for wind turbine production, including a cutting platform 1. For example, as shown... Figure 1 and Figure 2 As shown, a sheet metal placement mechanism 2 is provided on one side wall of the bottom of the cutting platform 1; two sets of first electric push rods 3 are symmetrically arranged on both side walls of the cutting platform 1; a sheet metal limiting mechanism 4 is drivenly connected to the output ends of the two sets of first electric push rods 3; a mounting base 5 is provided on one side wall of the top of the cutting platform 1; a rotating column 6 is provided on the top of the mounting base 5; a mounting plate 7 is drivenly connected to the top of the rotating column 6; a second electric push rod 8 is provided on the top of the end of the mounting plate 7 away from the rotating column 6; the output end of the second electric push rod 8 extends to the mounting plate 7. Below the plate 7, a horizontal drive mechanism 9 is connected via transmission; an array laser mechanism 10 is connected via transmission to the output end of the horizontal drive mechanism 9; a collection groove 14 is provided on the top of the cutting platform 1; two sets of guide frames 11 are symmetrically arranged on the top of the collection groove 14; a set of filter screens 12 is provided in each set of guide frames 11; two sets of baffles 13 are symmetrically inclined at the bottom of the opposite ends of the two sets of guide frames 11; a conveyor belt 15 is provided on the bottom inner wall of the collection groove 14; one end of the conveyor belt 15 extends to the outside of the cutting platform 1.

[0038] During the cutting of wind turbine blades, several metal sheets are first placed on the sheet placement mechanism 2. Then, two sets of first electric push rods 3 are controlled, followed by a rotating column 6 that, via a mounting plate 7, a second electric push rod 8, and a horizontal drive mechanism 9, drives the array laser mechanism 10 to rotate to one side. Next, the two sets of first electric push rods 3 drive the sheet limiting mechanism 4 to feed the corresponding metal sheets. Finally, the array laser mechanism 10 is controlled to reset and descend to cut the metal sheets into wind turbine blades. The molten slag generated during the cutting of multiple wind turbine blades is also processed. The slag and debris enter the collection tank 14 after passing through the filter screens 12 on the two sets of guide frames 11. The two sets of inclined baffles 13 prevent the slag and debris from falling on the top of the conveyor belt 15. When the cutting is completed, several sets of cut fan blades will fall on the top of the two sets of filter screens 12. Then, the two sets of guide frames 11 are controlled to rotate into the collection tank 14, so that several sets of fan blades can slide onto the top of the conveyor belt 15 for collection. This improves the slag and debris collection effect of the laser cutting equipment and also improves the feeding efficiency of the fan blades.

[0039] For example, such as Figure 3 and Figure 4 As shown, the sheet material placement mechanism 2 includes a placement plate 201; four sets of storage slots 202 are symmetrically opened on the top two sides of the placement plate 201; several sets of partition plates 203 are hinged to the top of each pair of adjacent sets of storage slots 202 at a staggered angle; a set of first sliding grooves 204 is opened between each pair of adjacent sets of storage slots 202; several sets of first sliders 205 are slidably connected in each set of first sliding grooves 204; a set of connecting rods 206 is rotatably connected to the corresponding side wall of each set of first sliders 205; the other end of each set of connecting rods 206 is rotatably connected to the corresponding set of partition plates 203; a set of first lead screws 207 is rotatably installed in each set of first sliding grooves 204; each set of first lead screws 207 is threadedly connected to the corresponding set of first sliders 205.

[0040] When cutting the fan blades, the placement plate 201 is first rotated and pressed against the ground. Then, the two sets of first lead screws 207 are rotated. With the threaded connection between the first lead screws 207 and several sets of first sliders 205, the several sets of first sliders 205 move horizontally and drive the partition plate 203 from the receiving groove 202 to the outside through the corresponding connecting rod 206. Then, several sets of metal plates can be placed between the corresponding partition plates 203, so that the adjacent metal plates can be spaced accordingly. This allows the plate limiting mechanism 4 to complete the automatic feeding work, improving the feeding efficiency of the fan blades of the laser cutting equipment.

[0041] For example, such as Figure 5 and Figure 6As shown, the sheet metal limiting mechanism 4 includes two sets of symmetrically arranged first electric slides 401; the output end of each set of first electric slides 401 is connected to the output end of a corresponding set of first electric push rods 3; each set of first electric slides 401 has a limiting plate 402 at its top; each set of limiting plates 402 has a second slide groove 403 at its top; each set of second slide grooves 403 has two sets of second lead screws 404; one end of each set of two sets of second lead screws 404 is fixedly connected, and the other end is rotatably connected to the inner walls of both sides of the second slide groove 403; the thread directions of the two sets of second lead screws 404 are opposite, and their central axes are on the same straight line; each set of second slide grooves 403 has a second slider 407 slidably connected; each set of second sliders 407 is connected to the corresponding... A set of second lead screws 404 are threadedly connected; a set of second electric slide tables 408 are provided at the top of each set of second sliders 407; two sets of first leveling rollers 405 and second leveling rollers 406 are arranged parallel between the two sets of limiting plates 402; both ends of each set of first leveling rollers 405 are respectively movably inserted into a corresponding set of second slide grooves 403 and are rotatably connected to the corresponding set of second sliders 407; both ends of each set of second leveling rollers 406 are respectively drivenly connected to the output end of the corresponding set of second electric slide tables 408; several sets of card plate movable grooves 409 are equally spaced on the inner wall of the opposite side of the two sets of second slide grooves 403; a set of card plates 410 is provided in each set of card plate movable grooves 409; several sets of card slots 411 are equally spaced on the top of each set of card plates 410.

[0042] During the cutting of wind turbine blades, the two sets of first electric push rods 3 are controlled to drive the plate limiting mechanism 4 to rotate and abut against one side wall of the metal plate. Then, the clamping plates 410 in several sets of clamping plate movable slots 409 are controlled to rotate towards the metal plate, so that the corresponding clamping slots 411 can be clamped at the edge of the metal plate to limit and fix the metal plate. After the metal plate is adjusted to be horizontal, the four sets of second electric slides 408 are controlled to drive the two sets of second leveling rollers 406 to rotate above the metal plate and abut against the top of the metal plate. Then, the four sets of second lead screws 404 are controlled to rotate. Under the threaded connection between the four sets of second lead screws 404 and the four sets of second sliders 407, the two sets of first leveling rollers 405 and the two sets of second leveling rollers 406 abut against the two sides of the metal plate respectively and reciprocate in the horizontal direction, thereby leveling the metal plate without affecting the automatic feeding of the metal plate, thus improving the processing quality of the laser cutting equipment.

[0043] For example, such as Figure 7As shown, the horizontal drive mechanism 9 includes a fixed plate 901; a movable groove 902 is provided at the bottom of the fixed plate 901; a set of third sliding grooves 903 are respectively provided on the four inner walls of the movable groove 902; two sets of opposite third sliding grooves 903 are symmetrically provided and are on different horizontal planes from the other two sets of third sliding grooves 903; a set of translation plates 904 are slidably connected in each set of third sliding grooves 903; a set of motors 905 are respectively provided on the two sets of vertical translation plates 904; a set of third lead screws 906 are drivenly connected to the output end of each set of motors 905; the other end of each set of third lead screws 906 is rotatably connected to the corresponding set of translation plates 904; a drive block 907 is provided in the movable groove 902; the drive block 907 is threadedly connected to both sets of third lead screws 906 and is drivenly connected to the array laser mechanism 10.

[0044] When cutting the wind turbine blades, two sets of motors 905 are controlled to drive two sets of third lead screws 906 to rotate. Since the two sets of motors 905 are located on different horizontal planes, the drive block 907 can move arbitrarily in the horizontal direction due to the threaded connection between the two sets of third lead screws 906 and the drive block 907. Thus, the drive block 907 drives the array laser mechanism 10 to cut the metal sheet into wind turbine blades.

[0045] For example, such as Figure 8 and Figure 9As shown, the array laser mechanism 10 includes a movable plate 1001; the bottom of the movable plate 1001 is provided with a plurality of sets of mounting blocks 1002 arranged in a rectangular array; each set of mounting blocks 1002 has a set of laser generators 1003 at its bottom; each set of mounting blocks 1002 is connected to a set of telescopic rods 1004 between it and the adjacent sets of mounting blocks 1002; a set of scaling rods 1005 are provided at the vertical two sides of the bottom of the movable plate 1001; each set of scaling rods 1005 is connected to the corresponding sets of mounting blocks 1002 at the edge; the movable plate 1001 is provided with an adjustment cavity 1006; the bottom of the adjustment cavity 1006 is provided with four sets of limiting grooves 1007 arranged in a ring array; the adjustment Two sets of sliding rods 1008 are slidably connected to the top inner wall of cavity 1006; two sets of fourth lead screws 1009 are provided inside the adjustment cavity 1006; one end of each set of fourth lead screws 1009 is fixedly connected, and the other end is rotatably connected to the inner walls on both sides of the adjustment cavity 1006; the threads of the two sets of fourth lead screws 1009 are opposite in direction, and their central axes are on the same straight line; each set of fourth lead screws 1009 is threadedly connected to a corresponding set of sliding rods 1008; two sets of guide posts 1010 are slidably connected to the bottom of each set of sliding rods 1008; each set of guide posts 1010 is slidably connected to a corresponding set of limiting grooves 1007; the bottom of each set of guide posts 1010 is drively connected to the mounting block 1002 at the corresponding corner.

[0046] When cutting wind turbine blades, several sets of laser generators 1003 are arranged in a rectangular array at the bottom of the movable plate 1001. This allows the horizontal drive mechanism 9 to drive the laser generators 1003 to perform multi-area synchronous laser cutting on the metal sheet through the movable plate 1001. Several sets of mounting blocks 1002 are connected by telescopic rods 1004, and the vertical two-sided edges are connected by scaling rods 1005. By controlling the synchronous rotation of two sets of fourth lead screws 1009, and with the threaded connection between the two sets of fourth lead screws 1009 and two sets of sliding rods 1008, the four sets of guide posts 1010 at the bottom of the two sets of sliding rods 1008 can move within the four sets of limiting grooves 1007 and drive the four sets of mounting blocks 1002 at the corners to move. This completes the scaling of the rectangular array of laser generators 1003, thereby completing the cutting of wind turbine blades of different sizes. This improves the processing efficiency of the laser cutting equipment for wind turbine blades and increases the processing range of the wind turbine blades.

[0047] By controlling the movable plate 1001 to drive several sets of laser generators 1003 arranged in a rectangular array to perform multi-area synchronous laser cutting on the metal sheet, and several sets of mounting blocks 1002 are connected to each other by telescopic rods 1004, and the vertical two side edges are connected by scaling linkages 1005. By controlling the horizontal movement of two sets of sliding rods 1008, the four sets of guide posts 1010 at the bottom of the two sets of sliding rods 1008 can move within four sets of limiting grooves 1007 and drive the four sets of mounting blocks 1002 at the corners to move, thereby completing the scaling of the rectangular array of several sets of laser generators 1003, and thus completing the cutting of wind turbine blades of different sizes. This improves the processing efficiency of the laser cutting equipment for wind turbine blades and increases the processing range of the wind turbine blades.

[0048] After the sheet metal is fed and fixed to a horizontal position by the sheet metal limiting mechanism 4, the four sets of second electric slides 408 are controlled to drive the two sets of second leveling rollers 406 to rotate above the sheet metal and abut against the top of the sheet metal. Then, the four sets of second lead screws 404 are controlled to rotate. Under the threaded connection between the four sets of second lead screws 404 and the four sets of second sliders 407, the two sets of first leveling rollers 405 and the two sets of second leveling rollers 406 abut against the two sides of the sheet metal and reciprocate in the horizontal direction, thereby leveling the sheet metal without affecting the automatic feeding of the sheet metal, thus improving the processing quality of the laser cutting equipment.

[0049] By controlling the placement plate 201 to rotate and press against the ground, and then controlling the rotation of the two sets of first lead screws 207, under the threaded connection between the first lead screws 207 and several sets of first sliders 205, the several sets of first sliders 205 move horizontally and drive the partition plate 203 to rotate from inside the receiving groove 202 to the outside through the corresponding connecting rod 206. Then, several sets of metal plates can be placed between the corresponding partition plates 203, so that the adjacent metal plates can generate the corresponding spacing, thereby enabling the plate limiting mechanism 4 to complete the automatic feeding work and improve the feeding efficiency of the fan blades of the laser cutting equipment.

[0050] The slag and debris generated during the cutting of multiple sets of fan blades enter the collection tank 14 after passing through the filter screens 12 on the two sets of guide frames 11. The slag and debris are prevented from falling on the top of the conveyor belt 15 by the two sets of inclined baffles 13. When the cutting is completed, several sets of cut fan blades will fall on the top of the two sets of filter screens 12. Then, the two sets of guide frames 11 are controlled to rotate into the collection tank 14, so that several sets of fan blades can slide onto the top of the conveyor belt 15 for collection. This improves the slag and debris collection effect of the laser cutting equipment and increases the feeding efficiency of the fan blades.
