Description

Technical Field

[0003] Blades are critical components of wind turbines. Their shape and materials directly affect the performance of the wind turbine. In order to ensure the overall strength of the blades, welding is often used for connection. Due to different application scenarios of wind turbines, there are many types of wind rotors, such as centrifugal wind rotors, axial flow wind rotors, etc. Among them, the structure of centrifugal wind rotors is more complicated, usually consisting of a left disk, a right disk and multiple blades distributed in the middle.

[0004] Due to the complex structure of the centrifugal wind wheel, it is usually necessary to weld and fix the blades one by one during welding. This method is inefficient, so an auxiliary ring is used to arrange and fix multiple blades to form a whole, and then the whole is welded to the left and right disks. After welding, the auxiliary ring is removed to obtain a complete wind wheel. However, in the prior art, the welding process of the auxiliary ring and the blades still lacks an efficient processing method.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, an efficient welding device for fan production provided by an embodiment of the present invention includes a drive box 1 and a support frame 2, the support frame 2 is located on one side of the drive box 1, and the drive box 1 and the support frame 2 are connected through a welding platform 3, and also includes:

[0035] A rotating assembly 4, the rotating assembly 4 is located at the top of the driving housing 1, the rotating assembly 4 includes a turntable 401 rotatably arranged on the top of the driving housing 1, the driving housing 1 is used to drive the turntable 401 to rotate, the top of the turntable 401 is fixedly connected with a disk 402, a plurality of plug-in boxes 403 with an open top structure are evenly arranged at the edge of the disk 402, an opening and closing fixing mechanism 404 is arranged in the middle of the disk 402, and the opening and closing fixing mechanism 404 is used to support and fix the auxiliary ring 15 for welding the fan blades 14 from the inside;

[0036] The blade conveying assembly 5 is located on the support frame 2. The blade conveying assembly 5 includes a guide box 501 fixedly connected to the top of the support frame 2. The top of the guide box 501 is an open structure. A plurality of fan blades 14 are arranged in the guide box 501. A pushing mechanism 502 for horizontally pushing the fan blades 14 is provided on the side of the guide box 501 away from the drive box 1. A feeding port 503 is provided at the bottom of the guide box 501 close to one end of the drive box 1;

[0037] The discharge port 503 corresponds to the position of the plug-in box 403 on the disk body 402, and a reserved vertical spacing is set between the discharge port 503 and the plug-in box 403. The reserved vertical spacing needs to be greater than the length of the fan blade 14 to ensure that the fan blade 14 can fall smoothly. The discharge port 503 is consistent with the cross-sectional shape of the fan blade 14 and the plug-in box 403.

[0038] In one embodiment of the present invention, when the device is in use, a plurality of fan blades 14 are stored in the guide box 501, and the fan blades 14 can be fixed and dropped by the cooperation of the pushing mechanism 502 and the feeding port 503, so that the uninterrupted feeding processing of the fan blades 14 can be realized. After dropping, the fan blades 14 will enter the plug-in box 403 and be fixed, and the opening and closing fixing mechanism 404 is fastened with an auxiliary ring 15. By controlling the rotation of the disk 402 and the continuous dropping of the fan blades 14, the fan blades 14 can be regularly arranged on the outside of the auxiliary ring 15, so that the auxiliary ring 15 can quickly form a shape that can be welded with the fan blades 14, and then the existing welding robot cooperates with the intermittent rotation of the disk 402 to complete the preliminary welding processing of the fan blades 14. In summary, the device can quickly combine the fan blades 14 into a circular arrangement that can be welded, such as Fig.10 As shown, it is only necessary to weld the fan blades 14 one by one subsequently, eliminating operations such as position alignment and splicing and fixing during the welding process, thereby significantly improving the welding efficiency of the fan blades 14.

[0039] It should be noted that the opening and closing fixing mechanism 404 supports and fixes the auxiliary ring 15 from the inside, and will not affect the welding work between the auxiliary ring 15 and the fan blade 14. The welding robot mentioned above is not described in detail in the present invention because the robot for multi-angle free welding in the prior art is already a very mature technology. The welding robot can be set on the welding platform 3, so that with the rotation of the disk 402, the welding robot can complete the welding work without a large range of movement. The fan blade 14 and the inner walls on both sides of the guide box 501 are clearance-matched, so that the pushing mechanism 502 can push the fan blade 14 to move smoothly laterally in the guide box 501.

[0040] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment of the present invention, the disk body 402 is provided with a plurality of guide slots 6 along its own radial direction, the opening and closing fixing mechanism 404 comprises a slider 4041 slidably arranged in the guide slot 6, the top of the slider 4041 is fixedly connected with a plate body 4042, the top of the plate body 4042 is fixedly connected with a transversely arranged horizontal plate 4043, the horizontal plate 4043 is fixedly connected with a limiting plate 4044, a predetermined spacing is arranged between the limiting plate 4044 and the end of the horizontal plate 4043 away from the plate body 4042, which is used to prevent the end of the horizontal plate 4043 from occupying the welding space between the auxiliary ring 15 and the fan blade 14 when the auxiliary ring 15 is fixed, and a driving structure 7 for driving the slider 4041 to move synchronously is arranged in the turntable 401;

[0041] The pushing mechanism 502 includes an installation box body 5021 fixedly arranged at the bottom of the guide box body 501, a straight groove is opened at the top of the installation box body 5021, the straight groove is connected with the inside of the guide box body 501, a horizontal push bar 5022 is slidably arranged in the straight groove, and a first telescopic member 5023 for driving the horizontal push bar 5022 to move horizontally is arranged in the installation box body 5021, and an elastic pad 5024 arranged toward the fan blade 14 is fixedly connected to the top of the horizontal push bar 5022.

[0042] In one case of this embodiment, the driving structure 7 includes a second telescopic member 701 fixedly connected to the bottom of the turntable 401 and arranged vertically. The top of the second telescopic member 701 is fixedly connected to the transfer platform 702. The bottom of the slider 4041 is located in the turntable 401. The bottom of the slider 4041 is rotatably connected to a transfer rod 703. The other end of the transfer rod 703 is rotatably connected to the transfer platform 702. When the second telescopic member 701 drives the transfer platform 702 to move in the vertical direction, the transfer platform 702 is connected to the transfer platform 702 through the transfer rod 703. The slider 4041 is driven to move in the guide slot 6. The first telescopic member 5023 and the second telescopic member 701 can be in the form of an electric telescopic rod, or in the form of a hydraulic telescopic rod. When the device is not in use, the second telescopic member 701 is in the shortest initial state. At this time, the slider 4041 is located at the innermost side of the guide slot 6, and the multiple plates 4042 above are all in a retracted state. When the device is in use, the second telescopic member 701 drives the slider 4041 to move through the transmission rod 703, so that The plate body 4042 is opened, and the auxiliary ring 15 can be opened and fixed by the cooperation of the limiting plate 4044 and the transverse plate 4043. The reserved spacing between the limiting plate 4044 and the end of the transverse plate 4043 away from the plate body 4042 needs to be smaller than the width of the auxiliary ring 15, so that after the auxiliary ring 15 is placed on the transverse plate 4043 and fixed, only a part of the inner side of the auxiliary ring 15 is in contact with the limiting plate 4044 and the transverse plate 4043, and the outer edge of the auxiliary ring 15 is in contact with the fan blade 14, and the transverse plate 4043 is The end will not affect the welding process of the two. When the first telescopic member 5023 is working, the fan blade 14 will be continuously pushed to the top of the discharge port 503 through the elastic pad 5024. When the elastic pad 5024 removes the force, the fan blade 14 will naturally fall into the plug-in box 403 below. At this time, the fan blade 14 will automatically stick to the auxiliary ring 15, and then cooperate with the driving box 1 to drive the turntable 401 and the disk 402 to rotate, so that the fan blade 14 can be evenly arranged around the auxiliary ring 15.

[0043] like Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, as a preferred embodiment of the present invention, the disk body 402 is provided with a plurality of holes, in which a shaft body 8 is rotatably connected, the plug box 403 is fixedly connected to the top of the shaft body 8, the shaft body 8 is in a state of penetrating the disk body 402, an adjusting wheel 9 is fixedly connected to the bottom of the shaft body 8, an adjusting ring 10 is rotatably provided at the bottom edge of the disk body 402, the inner wall of the adjusting ring 10 is in contact with the adjusting wheel 9, when the adjusting ring 10 rotates, the plurality of adjusting wheels 9 inside the adjusting ring 10 rotate synchronously and in the same direction, so that the relative angle between the plug box 403 at the top of the shaft body 8 and the disk body 402 changes;

[0044] The bottom of the guide box 501 is provided with a rotation adjustment structure 11 for adjusting the angle of the feed opening 503 . When the angle of the plug-in box 403 on the tray 402 changes, the rotation adjustment structure 11 is used to rotate the feed opening 503 to correspond to the angle of the plug-in box 403 .

[0045] In one case of this embodiment, a circular hole is provided at the bottom of the guide box 501, and the rotation adjustment structure 11 includes a tube 1101 fixedly arranged in the circular hole, a column 1102 is rotatably connected in the tube 1101, the feed port 503 is provided on the column 1102, a gear ring 1103 is fixedly connected at the bottom of the column 1102, a rotation driving member 1104 is provided on one side of the tube 1101 at the bottom of the guide box 501, and a driving gear 1104 matching the gear ring 1103 is fixedly connected at the output end of the rotation driving member 1104. 05. In actual situations, the angle of the fan blade 14 will be adjusted according to the purpose. The rotating drive member 1104 is used to drive the column 1102 to rotate. The rotating drive member 1104 can be in the form of a motor. Of course, the existing pneumatic motor can also be used. As long as the driving gear 1105 can be controlled to rotate, when the driving gear 1105 rotates, the column 1102 can be driven to rotate through the gear ring 1103, so that the angle of the discharge port 503 relative to the guide box 501 changes. Similarly, the disc 402 also needs to be adjusted. The plug box 403 on the shaft body 8 can be adjusted, and the adjusting wheel 9 can be rotated synchronously by rotating the adjusting ring 10, so that the plug box 403 on the shaft body 8 can be rotated. Of course, the rotation of the plug box 403 and the feed opening 503 needs to be unified, which can be achieved by using existing computer vision technology. The adjustment angle of the plug box 403 is monitored by an industrial camera, so as to control the rotation drive member 1104 to control the adjustment of the feed opening 503. In addition, the top of the tube body 1101 on the guide box 501 is an open structure, and the top of the column 1102 is fixed A vertically arranged baffle 1106 is connected, the baffle 1106 is located in the guide box 501 and the width of the baffle 1106 is smaller than the width of the guide box 501, the baffle 1106 is located on one side of the discharge port 503, and the side of the baffle 1106 facing the inside of the guide box 501 is flush with the discharge port 503. Due to the existence of the baffle 1106, when the pushing mechanism 502 pushes the fan blade 14, the fan blade 14 can automatically adjust its angle according to the baffle 1106 to keep it consistent with the direction of the discharge port 503, such as Figure 7As shown, an anti-skid structure 12 is provided on the side of the baffle 1106 facing the inside of the guide box 501. The anti-skid structure 12 can adopt a toothed anti-skid structure, and of course, it can also adopt a rubber friction anti-skid structure. Because of the existence of the anti-skid structure 12, when the fan blades 14 are pressed, a single fan blade 14 will not fall from the discharge port 503, and after the pressing effect is lost, the fan blade 14 will fall. In this way, the falling or stopping of the fan blade 14 can be controlled. The pressing effect is achieved by the pushing mechanism 502. Generally, the pushing mechanism 502 is only used for the lateral pushing and supplementing of the fan blades 14, but when the fan blades 14 fall, as long as the pushing mechanism 502 applies thrust to the entire fan blade 14, the falling will be stopped, and after the pushing mechanism 502 is retreated and released, the fan blades 14 can continue to fall.

[0046] like Figure 3 and Fig. 9 As shown, as a preferred embodiment of the present invention, position adjustment mechanisms 13 are provided on both sides of the top of the column 1102 on the guide box 501, and the position adjustment mechanism 13 includes a mounting frame 1301 fixedly connected to both sides of the guide box 501, and a telescopic driving member 1302 arranged toward the fan blade 14 in the guide box 501 is fixedly connected to the mounting frame 1301, and the output end of the telescopic driving member 1302 is fixedly connected to a positioning push plate 1303 located on both sides of the fan blade 14, and the telescopic driving member 1302 is used to drive the positioning push plate 1303 to move in the horizontal direction so that the fan blade 14 maintains a centered position in the guide box 501.

[0047] In one case of the present embodiment, the telescopic drive member 1302 can be an electric telescopic rod, and of course it can also be a hydraulic telescopic form. When the angle of the feed port 503 changes and becomes inclined, due to the pushing action of the elastic pad 5024, the fan blade 14 will be against the baffle 1106. However, because the fan blade 14 itself is also inclined, and there is a movable gap on both sides of the guide box 501, the fan blade 14 will shift to one side. The direction of the fan blade 14 shift can be monitored by an industrial camera, so that the telescopic drive member 1302 on the corresponding side can be started, and the positioning push plate 1303 will push the offset fan blade 14 to the middle position, so that the fan blade 14 can stably fall from the feed port 503.
