Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade technology, and in particular to a modular core material splicing device for wind turbine blades. Background Technology

[0002] In related technologies, wind turbine blades typically employ a "sandwich" structure, with an outer layer of glass fiber or carbon fiber composite material and a core of balsa wood or foam material sandwiched in between.

[0003] Please refer to the following: Figure 1 This is the specific structure of the modular core material 400 of the wind turbine blade in the prior art. The modular core material 400 usually requires cutting a large piece of balsa wood board 4001 into multiple small pieces of balsa wood board 4002, and then bonding and fixing the multiple small pieces of balsa wood board 4001 together with fiberglass connecting cloth 4003 to form a modular core material 400. By cutting it into multiple small pieces of balsa wood board 4002, gaps can be made between each small piece of balsa wood board 4002, so that it can be better fitted into the inside of the curved wind turbine blade.

[0004] Currently, splicing two modular core materials 400 requires manual placement of the two modular core materials 400 adjacent to each other, with a fiberglass overlap fabric 4001 placed between them. A welding device is then used to heat-fuse the fiberglass connecting fabric 4003 and the fiberglass overlap fabric 4004 between the two modular core materials 400 together. However, for the splicing operation between two modular core materials, operators need to cut fiberglass overlap fabric of appropriate length and overlap it on the fiberglass connecting fabric between the two modular core materials before transferring it to the welding device for heat-fuse welding. The manual feeding of fiberglass connecting fabric is time-consuming and labor-intensive, resulting in low production efficiency. Moreover, during the process of transferring the two modular core materials with the overlap fabric laid out to the welding device, the fiberglass overlap fabric is prone to misalignment. Once misalignment occurs, it will cause misalignment or incomplete connection problems in the subsequent heat-fuse welding of the two modular core materials, seriously affecting the reliability of the splicing between the modular core materials.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a modular core material splicing device for wind turbine blades, effectively solving the technical defects of low production efficiency and poor reliability of modular core material splicing in the existing technology.

[0007] This utility model provides a modular core material splicing device for wind turbine blades, including a first frame, a splicing support platform disposed on the first frame and used to support the modular core material, a pressing module disposed on the first frame and located above the splicing support platform, a welding module disposed on the frame and located below the splicing support platform, and a fabric pulling module disposed on the frame. The fabric spreading module includes a tray for storing fiberglass overlap fabric, a fabric clamping mechanism for holding the fiberglass overlap fabric on the tray, a Y-axis fabric spreading actuator for driving the fabric clamping mechanism to move back and forth, and an X-axis fabric spreading actuator for driving the fabric clamping mechanism to move left and right. After two modular core materials are fed onto the splicing support platform and the front-to-back spacing is set, the fabric clamping mechanism can clamp the fiberglass overlap fabric on the material tray, and through the coordinated action of the Y-axis and X-axis fabric pulling mechanisms, pull out the fiberglass overlap fabric and overlap it onto the fiberglass connecting fabric of the two modular core materials; or, After the clamping mechanism clamps the fiberglass overlap fabric, it is pulled out by the Y-axis and X-axis fabric pulling actuators. The two modular core materials are fed to the splicing support platform and the front and rear spacing is set. Then, the fiberglass connecting fabric is stacked on the fiberglass overlap fabric.

[0008] The advantages of the modular core material splicing device for wind turbine blades provided by this utility model are that, during operation, two modular core materials are input into the splicing support platform and the front and rear spacing is set. The X-axis cloth pulling actuator and the Y-axis cloth pulling actuator are linked with the cloth clamping mechanism to pull out the fiberglass overlap cloth and place it on the fiberglass connecting cloth between the two modular core materials. Finally, the cloth pressing module presses down the fiberglass overlap cloth and the fiberglass connecting cloth so that the welding module can hot melt weld the fiberglass overlap cloth and the fiberglass connecting cloth. Compared with existing technologies, firstly, the fiberglass overlap fabric is automatically pulled out and stacked on the fiberglass connecting fabric of two modular core materials, without the need for manual intervention in the stacking of the fiberglass overlap fabric. This reduces the labor intensity of operators and improves the splicing efficiency of modular core materials, making it particularly suitable for splicing large quantities of modular core materials. Secondly, after the modular core material completes the stacking of the fiberglass overlap fabric, welding can be carried out in situ, which can effectively avoid the fiberglass overlap fabric from becoming misaligned and ensure that there will be no welding misalignment or loose connection between the fiberglass overlap fabric and the fiberglass connecting fabric, thereby improving the splicing yield and splicing reliability of the modular core material.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figures 1 to 8 The modular core material splicing device 100 for wind turbine blades provided in the embodiments of this application will now be described.

[0027] The modular core material splicing device 100 for wind turbine blades includes a first frame 10, a splicing support platform 13 mounted on the first frame 10 for supporting the modular core material, a pressing module 20 mounted on the first frame 10 and located above the splicing support platform 13, a welding module 30 mounted on the frame and located below the splicing support platform 13, and a fabric spreading module 40 mounted on the frame; the fabric spreading module 40 includes a material tray 41 for storing fiberglass overlap fabric and a fabric clamping machine for clamping the fiberglass overlap fabric on the material tray 41. The structure includes a Y-axis fabric pulling actuator 43 for driving the fabric clamping mechanism 42 to move back and forth, and an X-axis fabric pulling actuator 44 for driving the fabric clamping mechanism 42 to move left and right. When the two modular core materials 400 are fed to the splicing support platform 13 and the front and rear spacing is set, the fabric clamping mechanism 42 can clamp the fiberglass overlap fabric on the material tray 41, and pull out the fiberglass overlap fabric to be stacked on the fiberglass connecting fabric of the two modular core materials 400 through the linkage of the Y-axis fabric pulling actuator 43 and the X-axis fabric pulling actuator 44.

[0028] During operation, two modular core materials 400 are input into the splicing support platform 13 and the front-to-back spacing is set. The X-axis fabric pulling actuator and the Y-axis fabric pulling actuator 43 are linked with the fabric clamping mechanism 42 to pull out the fiberglass overlap fabric and overlap it on the fiberglass connecting fabric between the two modular core materials 400. Finally, the fabric pressing module 20 presses down the fiberglass overlap fabric and the fiberglass connecting fabric so that the welding module 30 can perform hot-melt welding of the fiberglass overlap fabric and the fiberglass connecting fabric. Compared with the existing technology, firstly, the fiberglass overlap fabric is automatically pulled out and overlapped on the fiberglass connecting fabric between the two modular core materials 400. On the fabric, no manual intervention is required for the overlapping of the fiberglass overlap fabric, which can reduce the labor intensity of the workers and improve the splicing efficiency of the modular core material 400. It is particularly suitable for splicing large quantities of modular core material 400. Secondly, after the fiberglass overlap fabric of the modular core material 400 is stacked, welding can be carried out in situ, which can effectively avoid the fiberglass overlap fabric from being misaligned and ensure that there will be no welding misalignment or poor connection between the fiberglass overlap fabric and the fiberglass connecting fabric, thereby improving the splicing yield and splicing reliability of the modular core material 400.

[0029] Understandably, the fiberglass connecting fabric of the modular core material can also be stacked on top of the fiberglass overlap fabric, allowing the fiberglass overlap fabric to be heat-fused to the bottom of the fiberglass connecting fabric. Specifically, after the clamping mechanism 42 clamps the fiberglass overlap fabric, it is pulled out in conjunction with the Y-axis fabric pulling actuator 43 and the X-axis fabric pulling actuator 44. The two modular core materials are then fed onto the splicing support platform 13 and the front-to-back spacing is set, after which the fiberglass connecting fabric is stacked on top of the fiberglass overlap fabric.

[0030] In some embodiments, the X-axis fabric pulling actuator includes an X-axis frame 441 mounted on the first frame 10 and extending laterally, an X-axis guide rail 442 mounted on the X-axis frame 441 and extending laterally, an X-axis slider 443 movably mounted on the X-axis guide rail 442, an X-axis moving plate 444 fixedly mounted on the X-axis slider 443, and an X-axis actuator motor 445 mounted on the first frame 10 for driving the X-axis moving plate 444 to move. The Y-axis fabric pulling actuator 43 is mounted on the X-axis moving plate 444. The X-axis actuator motor 445 drives the X-axis moving plate 444 and the X-axis frame 441 to move via pulleys and belts.

[0031] More specifically, the Y-axis fabric pulling actuator 43 includes a Y-axis guide rail 431 located at the bottom of the X-axis moving plate 444 and extending back and forth, a Y-axis slider 432 movably located on the Y-axis guide rail 431, a Y-axis moving plate 433 fixedly located on the Y-axis slider 432, and a Y-axis cylinder 434 for driving the Y-axis moving plate 433 to move; the fabric clamping mechanism 42 is located on the Y-axis moving plate 433.

[0032] Furthermore, the fabric clamping mechanism 42 includes a first Z-axis guide rail 421 disposed at the bottom of the Y-axis moving plate 433, a first Z-axis slider 422 movably disposed at the first Z-axis guide rail 421, a first Z-axis moving plate 423 fixedly disposed at the first Z-axis slider 422, a second Z-axis guide rail 424 disposed at the bottom of the Y-axis moving plate 433, a second Z-axis slider 425 movably disposed at the second Z-axis guide rail 424, and a second Z-axis moving plate 426 fixedly disposed at the second Z-axis slider 425; The first Z-axis moving plate 423 is connected to a first Z-axis actuator cylinder 4231 for driving its up and down movement, and the first Z-axis moving plate 423 is provided with a first horizontal clamping plate 4232; the second Z-axis moving plate 426 is connected to a second Z-axis actuator cylinder 4261 for driving its up and down movement, and the second Z-axis moving plate 426 is provided with a second horizontal clamping plate 4262, and the first horizontal clamping plate 4232 is arranged above and below the second horizontal clamping plate 4262.

[0033] Understandably, when the two modular core materials are supported on the splicing support platform 13, the X-axis fabric pulling actuator and the Y-axis fabric pulling actuator 43 can move the clamping mechanism 42 to the left and closer to the position of the material tray 41. By driving the first horizontal clamping plate 4232 and the second horizontal clamping plate 4262 to move up and down, the fiberglass overlap fabric of the material tray 41 is pulled out. Then, the X-axis fabric pulling actuator and the Y-axis fabric pulling actuator 43 move the clamping mechanism 42 to the right again, so that the pulled-out fiberglass overlap fabric is superimposed on the fiberglass connecting fabric of the two modular core materials. Subsequently, through the cooperation of the pressing module 20 and the welding module 30, the hot melt welding operation of the fiberglass overlap fabric and the fiberglass connecting fabric can be completed.

[0034] In other embodiments, the material tray 41 is rotatably mounted on the X-axis frame 441 via a first pivot shaft 411, the first pivot shaft 411 being provided with a first gear 412; the X-axis frame 441 is provided with a feeding actuator motor 413, the shaft of the feeding actuator motor 413 being provided with a second gear 414, the second gear 414 being meshed with the first gear 412. This structure allows the feeding actuator motor 413 to drive the material tray 41 to rotate during the process of the X-axis fabric pulling actuator and the Y-axis fabric pulling actuator 43 being linked with the fabric clamping mechanism 42 to pull out the fiberglass overlap fabric, assisting in the release of the fiberglass overlap fabric, preventing the fiberglass overlap fabric from breaking during the pulling process, thereby improving the production reliability of the modular core material splicing device 100.

[0035] Specifically, the fiberglass overlap fabric needs to be released with the assistance of the feeding mechanism 45, which can further improve the reliability of the fiberglass overlap fabric release. The feeding mechanism 45 includes a feeding base plate 451, a first pressure roller 452, a second pressure roller 453, a third pressure roller 454, and a fourth pressure roller 455. The feeding base plate 451 is fixedly mounted on the first frame 10; the first pressure roller 452 is rotatably mounted on the first pressing moving seat 4521, and the first pressing moving seat 4521 is movable up and down on the feeding base plate 451. Through the elastic component, it can continuously provide a downward force to the first pressing moving seat 4521; the second pressure roller 453 is rotatable. The third pressure roller 454 is rotatably mounted on the second pressing moving plate 4541, which is movable up and down on the guide plate 451. The second pressing moving plate 4541 is connected to a pressing cylinder 4542 for driving its up and down movement. The third pressure roller 454 is located to the right of the first pressure roller 452. The fourth pressure roller 455 is rotatably mounted on the guide plate 451 and located below the third pressure roller 454.

[0036] Understandably, after the fiberglass overlap fabric is released from the tray 41, it first passes through the first pressure roller 452 and the second pressure roller 453, and then through the third pressure roller 454 and the fourth pressure roller 455. The fabric clamping mechanism 42 clamps the fiberglass overlap fabric from the right side of the third pressure roller 454 and the fourth pressure roller 455.

[0037] More specifically, it also includes a first fabric cutting mechanism 46, which includes a first fabric cutting knife 461 and a first fabric cutting execution cylinder 462. One end of the first fabric cutting knife 461 is rotatably mounted on the first frame 10 and located to the right of the third pressure roller 454. The first fabric cutting execution cylinder 462 is mounted on the first frame 10 and is used to drive the first fabric cutting knife 461 to swing and cut the fiberglass overlap fabric.

[0038] Understandably, once the pulled-out fiberglass overlap fabric and the fiberglass connecting fabric are thermally welded together, the first cutting blade 461 can be driven by the first cutting cylinder 462 to swing and cut the fiberglass overlap fabric. Before cutting the fiberglass overlap fabric, the pressing cylinder 4542 drives the third pressing roller 454 to move toward the fourth pressing roller 455 to clamp and fix the fiberglass overlap fabric.

[0039] In some other embodiments, the first frame 10 includes a left base 11 and a right base 12, with the left base 11 and the right base 12 spaced apart to the left and right, and the two ends of the X-axis frame 441 are installed corresponding to the left base 11 and the right base 12.

[0040] Specifically, the fabric pressing module 20 includes a second crossbeam 21 installed on the left base 11 and the right base 12, a fabric pressing plate 22 movable up and down on the bottom of the second crossbeam 21, and a fabric pressing cylinder 23 for driving the fabric pressing plate 22 to move up and down; the second crossbeam 21 is provided with a first guide hole 211 penetrating its upper and lower surfaces, and the top of the fabric pressing plate 22 is provided with a first guide rod 221 that can be moved up and down and inserted into the first guide hole 211. The welding module 30 includes a third crossbeam 31 installed on the left base 11 and the right base 12, a heating plate 32 movable up and down on the top of the third crossbeam 31, and a welding execution cylinder 33 for driving the heating plate 32 to move up and down; the third crossbeam 31 is provided with a second guide hole 311 penetrating its upper and lower surfaces, and the bottom of the heating plate 32 is provided with a second guide rod 321 that can be moved up and down and inserted into the second guide hole 311.

[0041] Understandably, the modular core material 400 splicing device 100 can be installed on the belt conveyor 200. After at least two modular core materials are input into the splicing support platform 13 via the belt conveyor 200, the fiberglass overlap fabric is pulled out and stacked on the fiberglass connecting fabric of the two modular core materials by the fabric spreading module 40. After the fiberglass overlap fabric and the fiberglass connecting fabric are thermally fused together by the cooperation of the fabric pressing module 20 and the welding module 30, the fiberglass overlap fabric is cut by the first fabric cutting mechanism 46, and then transferred and unloaded by the belt conveyor 200. At the same time, the belt conveyor 200 is provided with a feeding device 300 for feeding modular core materials. The feeding device 300 can feed a whole modular core material onto the belt conveyor 200, and the belt conveyor 200 transports the modular core material to be supported on the splicing support platform 13.

[0042] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
