Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade manufacturing technology, and in particular to a blade burr cutting device. Background Technology

[0002] During the manufacturing process of blades (such as wind turbine blades and aircraft blades), since blades are usually formed using a mold forming process, a flash will form around the edge of the blade when it is demolded after the mold is closed and the casting process is completed. This flash mainly consists of two parts: one part is the fastening surface structure formed when the blade mold is closed, and the other part is the mold-closing glue that overflows during the molding process. The flash composed of the two directly affects the appearance quality, dimensional accuracy, and subsequent assembly performance of the blade. Therefore, it must be cut off and removed in the subsequent processing of the blade. Currently, in the blade manufacturing industry, most factories still use manual cutting to remove the aforementioned flash. The specific operating procedure is usually as follows: the operator holds a cutting tool (such as an angle grinder, a special cutting knife, etc.) and manually cuts around the flash area on the edge of the blade. During the cutting process, the cutting force and angle need to be continuously adjusted according to the actual thickness of the flash and the structural characteristics of the fastening surface to ensure that the flash is completely removed without damaging the blade structure. Manual cutting of blade burrs has several drawbacks in actual production. Firstly, it generates a large amount of cutting dust. Since the cutting operation is mostly handheld and mobile, existing dust collection equipment struggles to effectively collect and treat the dust, causing it to permeate the workshop and harm the respiratory health of operators. Secondly, it is unsafe and requires high skill levels. During manual cutting, operators must be in close contact with high-speed cutting tools and constantly move around the blade edge, increasing the risk of injury from tool cuts or damage to the blade itself due to operational errors. Furthermore, it is difficult to guarantee the accuracy of burr cutting. In addition, production efficiency is low. Manual cutting is limited by personnel strength, operating speed, and cutting accuracy requirements, resulting in low efficiency that cannot meet the demands of large-scale, high-efficiency blade production. Therefore, a blade burr cutting device needs to be designed.

[0003] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 7-9As shown in the figure, the blade trimming device provided in this embodiment of the present invention includes an AGV vehicle 1, which serves as the mobile carrier of the device and can achieve automatic navigation and movement. A controller 13 is fixed on the AGV vehicle 1, which is used to receive signals from various sensors and coordinate the operation of various components such as the AGV vehicle 1. At the same time, a dust collection device 12 is fixed on the AGV vehicle 1, which is used to collect dust generated during the operation of the device, maintain the cleanliness of the working environment, and protect the equipment and operators. Furthermore, a device for... A cutting device 4 for cutting the edge of blade flash, and the cutting device 4 includes a guide unit disposed above the AGV vehicle 1. The guide unit is used to cooperate with the AGV vehicle 1 to move along the arc of the blade flash. The guide unit includes a fixed cover 41 with a V-shaped opening 42 on the side. An industrial vision camera 45 is fixed on the side of the fixed cover 41 by a connecting plate 44. The industrial vision camera 45 is tilted and used to scan the lower surface of the blade flash from a suitable position to input the scanned image into the controller 13. Meanwhile, an industrial vision camera 2 47 is fixed on the fixed cover 41 and above the connecting plate 44 via an extension plate 46. The industrial vision camera 2 47 is set opposite to the industrial vision camera 1 45 and is used to scan the upper surface of the blade flash. The scanned image is input into the controller 13, which processes the image information fed back by the vision camera, calculates the cutting trajectory, and controls the working parameters of the cutting unit. Thus, by using the industrial vision camera 2 47 and the industrial vision camera 1 45 together, the curvature of the blade flash is identified for guidance, thereby indirectly controlling the movement of the AGV vehicle 1. Furthermore, an industrial vision camera 3 48 is fixed on the extension plate 46 and to one side of the industrial vision camera 2 47. The industrial vision camera 3 48 is used to scan the upper surface of the blade flash to scan the blade flash in place and achieve the guiding function. Furthermore, a trimming unit is provided inside the fixed cover 41. This trimming unit includes two sets of transmission wheels 415 connected to the fixed cover 41 bearings via a transmission shaft 417. The two sets of transmission wheels 415 are arranged vertically, and a band saw 416 is connected between them. In actual use, a portion of the band saw 416 can be exposed at the V-shaped opening 42. A motor (not shown in the figure) is fixed to the outer side of the fixed cover 41. The motor provides power to the trimming unit. The output end of the motor extends through into the fixed cover 41 and is fixed with a drive wheel 418. The drive wheel 418 is located to one side of the transmission wheels 415. A driven wheel (not shown in the figure) is sleeved on the drive shaft 417. A synchronous belt 419 connects the drive wheel 418 and the driven wheel. The driven wheel and the drive wheel 418 cooperate through the belt to transmit the rotational power of the motor to the drive shaft 417, which in turn drives the drive wheel 415 to rotate. Through the synchronous linkage of the upper and lower sets of drive wheels 415, the friction between the band saw 416 and the drive wheel 415 is used to drive the band saw 416 to form a closed-loop high-speed motion trajectory, so that the part of the band saw 416 exposed in the V-shaped opening 42 can obtain continuous and stable cutting power, ensuring efficient cutting of blade burrs. A dust removal unit is provided on the fixed cover 41. This unit includes a dust collection component 43 fixed to the outer side of the fixed cover 41 and on the same side as the industrial vision camera 45. The dust collection component 43 collects dust generated during the cutting process, preventing dust from spreading and affecting equipment operation and the working environment. The dust collection component 43 is vertically positioned, with one end aligned with the V-shaped opening 42 and bent. A suction pipe 49 is connected to the bottom surface of the fixed cover 41 near the band saw 416. Dust pipe 49 is used to collect cutting dust that falls into the fixed cover 41. Dust baffles 410 are fixed on both sides of the inner wall of the fixed cover 41 and near the lower drive wheel 415. The dust baffles 410 are used to prevent cutting dust from falling into the bearing of the lower drive wheel 415, thus protecting the bearing from dust. A suction pipe 414 is fixed on the side of the fixed cover 41 and near the upper drive wheel 415. One suction end of the suction pipe 414 is aligned with the inner side of the band saw 416 (see reference). Figure 9 This is used to absorb dust adhering to the inner surface of the band saw 416, keep the band saw 416 clean, and ensure cutting results; Two sets of symmetrically arranged limiting units are provided on the inner wall of the fixed cover 41 and extending out of the V-shaped opening 42. Each limiting unit includes a mounting block 411 fixed to one side of the inner wall of the fixed cover 41, and two sets of contact portions are provided on the mounting block 411. The two sets of contact portions are arranged perpendicular to each other, and each contact portion includes a limiting member 413 with a bearing mounted on the mounting block 411. A rotating ring 412 is movably nested on the limiting member 413. The rotating ring 412 contacts the band saw 416. While limiting the band saw 416, it reduces the friction between the limiting member 413 and the band saw 416 by rotating itself. It should be noted that the rotating ring 412 of the two sets of contact portions contacts the side and surface of the band saw 416 respectively to limit the band saw 416.

[0021] like Figures 10-11 As shown, a cutting assembly 5 is provided on one side of the cutting device 4. The cutting assembly 5 is used to cut the wind turbine blades after they have been cut by the cutting device 4. The cutting assembly 5 includes a support bracket 51, and a dust collection hood 52 is fixed on the support bracket 51. The dust collection hood 52 is used to collect the dust generated by the saw blade 515 during cutting, and at the same time, it protects the saw blade 515 to prevent cutting debris from flying. The bottom of the dust collection hood 52 is connected to a dust suction pipe (not shown in the figure). The dust pipe is suitable for connecting to the dust suction device 12 through a flexible hose. One side of the dust collection hood 52 has an open groove (not shown in the figure) for the blade edge to pass through. Furthermore, a cutting unit is provided inside the dust collection hood 52. This cutting unit includes a saw blade 515 disposed within the dust collection hood 52. The saw blade 515 has a central drive shaft 513, which penetrates the dust collection hood 52. A groove 53 is provided on the dust collection hood 52 for the vertical sliding of the drive shaft 513. The groove 53 provides space for the vertical displacement of the drive shaft 513, allowing the saw blade 515 to adapt to the requirements of blade edge cutting. An assembly cover 520 is provided on one side of the dust collection hood 52, and a dust cover 59 is fixed to the side of the assembly cover 520. The inner side of the dust collection hood 52 is fixed... There are two sets of bearing seats 512 spaced apart for supporting the drive shaft 513. The drive shaft 513 passes through the two sets of bearing seats 512 and extends into the dust cover 59, where a second pulley 514 is fixed. At the same time, a third motor 510 is fixed on the bottom surface of the assembly cover 520. The third motor 510 is the power source of the cutting unit. Through the transmission of the first pulley 511, the belt body, and the second pulley 514, it provides rotational power to the saw blade 515. The output end of the third motor 510 extends into the dust cover 59 and is fixed with the first pulley 511. A belt body (not shown in the figure) connects the first pulley 511 and the second pulley 514. Meanwhile, an auxiliary frame (not shown in the figure) is fixed near one side of the support bracket 51. This auxiliary frame is equipped with a displacement unit, which drives the cutting unit to achieve vertical displacement, thereby realizing the sawing operation of the saw blade 515. The displacement unit includes two sets of slide rails 519 fixed to the side of the auxiliary frame, and a sliding plate 516 is slidably mounted on the two sets of slide rails 519. The assembly cover 520 is fixed to the sliding plate 516 via a connecting plate 521, allowing the assembly cover 520 to move synchronously with the sliding plate 516. The assembly cover 520 and the sliding plate 516... There is an installation gap between them, and a motor 517 is fixed on the side of the sliding plate 516 and within the installation gap. A bevel gear box 522 is connected to the side of the motor 517. The bevel gear box 522 is used to change the power output direction of the motor 517. The bevel gear box 522 has a steering shaft, and a gear is fixed on the steering shaft. At the same time, a vertically arranged rack 518 is fixed on the auxiliary frame between the two sets of slide rails 519. The rack 518 meshes with the gear and converts the rotational motion of the motor 517 into the vertical linear motion of the sliding plate 516. A support unit for supporting the blade burrs is provided on the side of the support bracket 51. The support unit is used to support the blade burrs during the sawing process to prevent the burrs from deforming due to their own weight or cutting force, thus ensuring sawing accuracy. The support unit includes an auxiliary bracket 55 fixed to the side of the support bracket 51. The auxiliary bracket 55 has a vertical panel, and two sets of vertically arranged slide rails 56 are fixed on the vertical panel. Support plates 57 are slidably arranged on the two sets of slide rails 56 via sliders. Support wheels 58 are provided on the side bearings of the support plates 57. The support wheels 58 contact the blade burrs and, while providing support, reduce friction with the burrs by rotating themselves, thus avoiding damage to the burr surface. A cylinder (not shown in the figure) is fixed on the side of the auxiliary bracket 55, and the telescopic end of the cylinder is connected to the support plate 57.

[0022] like Figure 1 and Figures 4-7 As shown, a moving device 3 is provided above the AGV vehicle 1 to realize the horizontal position adjustment of the cutting device 4 and the cutting component 5. The moving device 3 includes a cross frame 31, and a mounting cover 33 is fixed on the cross frame 31. A motor 34 is fixed to one end of the mounting cover 33. The output end of the motor 34 extends through into the mounting cover 33 and is fixed to a lead screw 35 through a coupling. A lead screw nut 36 is threadedly connected to the lead screw 35. The lead screw 35 converts the rotational motion of the motor 34 into the linear motion of the lead screw nut 36 through the threaded engagement with the lead screw nut 36. At the same time, a T-shaped frame 37 is fixed to the lead screw nut 36 through an angle plate. The T-shaped end of the T-shaped frame 37 extends out of the mounting cover 33. An opening slot 32 is provided at one end of the T-shaped frame 37. Guide rails 310 are fixed on both sides of the lead screw 35 on the cross frame 31. Meanwhile, sliding blocks 39 are fixed at both ends of the bottom surface of the corner plate and are slidably mounted on the guide rail 310. The sliding blocks 39 slide on the guide rail 310 to reduce friction when the T-shaped frame 37 moves horizontally. Together with the screw nut 36, they achieve stable displacement of the T-shaped frame 37. A chain 38 is connected to the side of the T-shaped frame 37. The fixed cover 41 and the bearing bracket 51 are both fixedly mounted on the bottom surface of the T-shaped frame 37. The T-shaped frame 37 is designed in a T shape to share the support pressure of the vertical part of the T-shaped frame 37, ensuring the stability of the structure when bearing the cutting device 4 and the cutting assembly 5.

[0023] like Figures 1-3 As shown, an AGV 1 is equipped with a lifting device 2 for adjusting the height of the cutting edge device 4 and the cutting assembly 5. The lifting device 2 includes a first mast 21 fixed to the AGV 1, and a mounting bracket 22 vertically fixed to the first mast 21. A lead screw 23 is mounted on the mounting bracket 22, and a sliding seat 24 is threaded onto the lead screw 23. A second mast 25, vertically arranged and parallel to the first mast 21, is fixed to the sliding seat 24. Sliding members 210 are fixed on both sides of the second mast 25, and guide rails cooperate with the sliding members 210 to form the second... The vertical lifting of the gantry 25 provides guidance, and a guide rail (not shown in the figure) that is slidably adapted to the sliding member 210 is fixed on the surface of the first gantry 21. A bevel gear reducer motor 29 is fixed on the first gantry 21 near the top. The bevel gear reducer motor 29 transmits power to the lead screw 23 through bevel gear transmission, realizing the rotation of the lead screw 23. This drives the lead screw 23 to convert the rotational motion of the bevel gear reducer motor 29 into the vertical linear motion of the sliding seat 24 through the threaded engagement with the sliding seat 24, thereby realizing the lifting power transmission of the second gantry 25. Two sets of vertically arranged slide rails 26 are fixed on the surface of the second gantry 25, and mounting parts 27 are slidably connected to both sets of slide rails 26. The cross frame 31 is connected and fixed to the two sets of mounting parts 27. At the same time, two sets of sprockets 211 are movably arranged on the top of the second gantry 25 through a support bracket. A hanging chain 212 is engaged on the sprocket 211. One end of the hanging chain 212 is fixedly connected to the cross frame 31 through a hanging ring, and the other end is connected to the top of the first gantry 21 through a hanging ring. The sprocket 211 is used to change the transmission direction of the hanging chain 212, so as to realize the synchronous lifting and lowering traction of the cross frame 31 by the hanging chain 212. At the same time, the hanging chain 212 transmits the lifting and lowering movement of the second gantry 25 to the cross frame 31 synchronously through the meshing transmission with the sprocket 211, which plays the role of auxiliary support and synchronous transmission. Meanwhile, a chain 28 is arranged on the side of the first gantry 21, and one end of the chain 28 is connected to the side of the mounting part 27.

[0024] Working principle: After the equipment is started, the AGV 1, as a mobile carrier, is automatically navigated under the coordinated control of the controller 13, in conjunction with the scanning and identification of the blade flash by the industrial vision cameras 45, 47, and 48 in the guiding unit, so that the equipment initially approaches the blade flash. At the same time, the lifting device 2 drives the lead screw 23 to rotate through the bevel gear reducer motor 29, which drives the sliding seat 24 and the second gantry 25 to rise and fall vertically along the guide rail, adjusting the height of the edge cutting device 4 and the cutting assembly 5. The moving device 3 is driven by the motor 34 to rotate the lead screw 35. Through the cooperation of the lead screw nut 36, the sliding block 39 and the guide rail 310, combined with the speed-increasing transmission of the chain 38, the horizontal displacement of the T-shaped frame 37 is realized, thereby adjusting the edge cutting device 4 and the cutting assembly 5 to the spatial position corresponding to the blade flash, preparing for the cutting operation.

[0025] Once the cutting device 4 is positioned correctly, the motor of its internal cutting unit starts, and power is transmitted to the transmission shaft 417 via the drive wheel 418, belt, and driven wheel, driving the two sets of transmission wheels 415 to rotate, thereby causing the band saw 416 to form a high-speed cyclic motion. At this time, the blade burrs enter the cutting area through the V-shaped opening 42 of the fixed cover 41, and the high-speed band saw 416 cuts the burrs. Simultaneously, the dust collection unit's dust collection components 43, dust collection pipe one 49, and dust collection pipe two 414 work together to collect the dust generated during cutting. The dust baffle brush 410 prevents dust from entering the bearings of the transmission wheel 415, keeping the inside of the equipment clean. The rotating ring 412 of the limiting unit limits the band saw 416 from the side and surface, ensuring stable movement of the band saw 416 and guaranteeing cutting accuracy.

[0026] After being cut by the trimming device 4, the blade burrs enter the working range of the cutting assembly 5. First, the cylinder of the support unit drives the support plate 57 to move along the slide rail 2 56, so that the support wheel 58 contacts the blade burrs and supports them. Then, the motor 4 517 of the displacement unit starts, and after changing the power direction through the bevel gear box 522, it drives the sliding plate 516 to move vertically along the slide rail 3 519 through the meshing transmission of the gear and rack 518, adjusting the height of the saw blade 515. At the same time, the motor 3 510 of the cutting unit starts, and the power is transmitted to the drive shaft 513 through the pulley 1 511, the belt body and the pulley 2 514, driving the saw blade 515 to rotate at high speed to cut off the blade burrs. The dust collection hood 52 collects the dust generated during the sawing process and transports it to the dust collection device 12 through the dust suction pipe to achieve centralized dust treatment.

[0027] Throughout the operation, AGV 1 continuously adjusts its movement trajectory based on feedback from the vision camera to ensure consistency with the curvature of the blade flash. The lifting device 2 and the moving device 3 adjust the height and horizontal position of the cutting device 4 and the cutting assembly 5 in real time according to the cutting progress and changes in the spatial position of the blade flash, ensuring the continuity of the cutting operation. After a section of blade flash is cut, the equipment, under the control of controller 13, repeats the above position adjustment and cutting process to achieve automated cutting and sawing of the entire blade flash, ultimately completing the processing of the wind turbine blade flash.
