Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically to a large-scale irrigation impeller assembly machine. Background Technology

[0002] In electrical and energy science, a wind turbine rotor is a component that converts wind energy into mechanical energy. It consists of blades and a hub. Wind turbine rotors have a wide range of applications, including in electrical devices. The general structure of a wind turbine rotor includes: an upper fixing ring / plate, blades, and a lower fixing ring / plate. The blades are riveted between the upper and lower fixing rings / plates. The size and dimensions of wind turbine rotors manufactured by different companies may vary, and the specific structure of the rotor may have slight differences, but they are all based on the above structure.

[0003] Previously, wind turbines were traditionally assembled manually, which was inefficient and produced poor quality, failing to meet production demands. However, with the development of automation, there is a desire to replace manual assembly with automated methods, aiming to improve the efficiency and quality of wind turbine assembly.

[0004] However, some existing automated assembly equipment can only assemble smaller wind turbines and cannot assemble larger ones. For example, Chinese patent announcement CN210209366U discloses an automated assembly equipment for large wind turbines, including a frame, a wind turbine mold, a top clamping assembly, a locking and riveting assembly, and an insert assembly. Although this patent technology claims to be able to assemble large wind turbines, these large wind turbines specifically refer to those with a large diameter but a small height, and the insert assembly is done using a wind turbine mold. This technology cannot be used to automatically assemble some taller, flow-driven wind turbines.

[0005] In view of this, the applicant proposes the following technical solution. Utility Model Content

Detailed Implementation

[0056] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0057] For large-scale irrigation wind turbine assembly machines, please refer to [link / reference]. Figure 1-2 As shown, it includes: a frame 100, a blade forming mechanism 200, a blade insertion mechanism 300, and a riveting mechanism 400; as Figure 2 As shown below, the following describes the positional direction when moving between various mechanisms, in order to... Figure 2 The coordinate directions shown are the reference, where X is horizontal, Y is horizontal, and Z is vertical.

[0058] like Figure 1 As shown, the frame 100 is a cabinet-type frame, which allows the assembly of the flow fan to be carried out in a relatively enclosed environment to prevent accidental injury to the user. The bottom of the frame 100 is equipped with rollers, support feet and other structures to facilitate the handling and positioning of the equipment. The frame 100 is also equipped with a viewing window to facilitate the user to observe the working status of the equipment.

[0059] like Figure 3 As shown, the blade forming mechanism 200 has a transfer forming roller assembly 210, a forming cutting assembly 220, an upper transfer track assembly 230 and a lower transfer track assembly 240. The general arrangement order is that the forming cutting assembly 220 is located to the right of the transfer forming roller assembly 210, the upper transfer track assembly 230 is located to the right of the forming cutting assembly 220, and the lower transfer track assembly 240 is located below the upper transfer track assembly 230.

[0060] like Figure 4-5 As shown, the blade forming mechanism 200 is mounted on the blade forming mechanism support 201. The specific structure of the blade forming mechanism support 201 is not limited, as long as it can provide support and positioning. The transmission forming roller assembly 210 includes at least two rollers 211 distributed vertically. When the two rollers 211 rotate in opposite directions, they can drive the blade 01 between them to move and be transmitted.

[0061] like Figure 4 As shown, this embodiment is provided with four rectangularly distributed rollers 211, which can realize the transmission of the blade 01;

[0062] In other embodiments, the number of rollers 211 may be changed;

[0063] Continue as Figure 4 As shown, pressure blocks 202 are provided at the beginning and end of the transmission path of the transmission forming roller assembly 210, which enables the blade 01 to smoothly enter the two rollers 211 at the beginning for transmission, and the blade 01 to smoothly enter the forming and cutting assembly 220.

[0064] like Figure 5 As shown, the rotation of roller 211 is transmitted through transmission component 212. The structure of transmission component 212 is varied. It can be directly driven by a motor to make roller 211 rotate, or it can be driven by a gear transmission assembly to make roller 211 rotate, or it can be driven by a belt rotation assembly to make roller 211 rotate. The four rollers 211 rotate synchronously.

[0065] Continue as Figure 5 As shown, in this embodiment, the transmission component 212 is a combination of a belt transmission assembly and a gear transmission assembly to drive the rollers 211. During the transmission process, multiple rollers 211 can rotate synchronously.

[0066] like Figure 4-5 As shown, the forming and cutting assembly 220 includes a blade holder 221, a blade (not shown in the figure) and a blade drive 222. The blade holder 221 has a gap in the middle through which the blade 01 passes. The blade 01 is transmitted from the roller 211 and enters the blade holder 221 through the pressure block 202. The blade drive 222 drives the blade to move from top to bottom to cut the blade 01. The cut blade 01 is supported on the upper transmission track assembly 230.

[0067] The blade drive component 222 can be a cylinder, a cam drive structure, a belt drive structure, etc., as long as it can drive the blade to move up and down to achieve the cutting purpose;

[0068] like Figure 4As shown, a recycling rail 223 is provided below the cutter holder 221 to collect the waste generated during the cutting process.

[0069] like Figure 6 As shown, the upper transmission track assembly 230 is connected to the end of the forming and cutting assembly 220 to receive the cut blade 01. Sensors or corresponding counters should be installed on the large-scale wind turbine assembly machine. During the transmission process, the blade 01 passes through the cutter holder 221 and is supported on the upper transmission track assembly 230. When the blade 01 reaches the set length, the transmission forming roller assembly 210 stops running, and the forming and cutting assembly 220 runs to cut the blade 01.

[0070] like Figure 6-7 As shown, the upper transmission track assembly 230 includes: an upper transmission track bracket 231, an upper transmission track 232, an upper pressure plate 233, and an upper transmission track drive member 234; the upper transmission track 232 has a plurality of linearly arranged and spaced upper support teeth 2321, the upper pressure plate 233 is correspondingly located above the upper transmission track 232 and forms a gap between it and the upper transmission track 232 for the blade to pass through; the upper transmission track drive member 234 drives the upper transmission track 232 to move up and down;

[0071] The lower transfer track assembly 240 includes: a lower transfer track bracket 241, a lower transfer track 242, and a robot arm 243; the lower transfer track 242 has a plurality of linearly arranged and spaced lower support teeth 2421, and the upper support teeth 2321 and the lower support teeth 2421 are staggered; the robot arm 243 pushes the blade 01 on the lower transfer track 242 to the blade insertion station and inserts it into the fixing ring 02;

[0072] One of the upper transmission track 232 or the lower transmission track 242 is connected or installed on a transverse slide rail, so that the upper transmission track 232 and the lower transmission track 242 can move closer or further apart in the X direction.

[0073] Specifically, the upper pressure plate 233 serves as a limit to prevent the blade 01 from detaching from the upper transmission track 232 during transmission. The upper transmission track 232 and the upper pressure plate 233 can be driven by the upper transmission track drive 234 to move in the Z direction (i.e., the longitudinal direction) to approach the lower transmission track assembly 240.

[0074] The upper transmission track 232 and the upper pressure plate 233 can be assembled as a whole on a bracket. The bracket is mounted on the transverse slide rail of the upper transmission track bracket 231, and the transverse slide rail can be mounted on the longitudinal slide rail. Then, the bracket is driven to move on the transverse slide rail by a driving component, and the transverse slide rail is driven to move on the longitudinal slide rail by the upper transmission track driving component 234. Finally, the upper transmission track 232 is moved in the X and Z directions.

[0075] The specific action of blade 01 moving from the upper transmission track 232 to the lower transmission track 242 can be: the upper transmission track 232 moves in the X direction under the drive of the driving component, and moves until the upper transmission track 232 and the lower transmission track 242 are vertically aligned;

[0076] Next, the upper transmission track drive 234 drives the upper transmission track 232 to move down. Since the upper support tooth 2321 and the lower support tooth 2421 are staggered, when the upper transmission track 232 moves to a position lower than the lower transmission track 242, the blade 01 is supported on the lower transmission track 242.

[0077] Then, the upper transmission track 232 moves and resets in the X direction under the drive of the driving element;

[0078] Finally, the upper transmission track drive 234 drives the upper transmission track 232 to move upward and reset.

[0079] In this way, the blade 01 was moved from the upper transport track 232 to the lower transport track 242.

[0080] The upper transfer track 232 continues to support the subsequent blade 01. The upper transfer track 232 continues to support the subsequent blade 01.

[0081] Furthermore, a belt drive assembly 244 is provided on the lower transmission track assembly 240, and the robot arm 243 is driven to move in the lower transmission track 242 through the belt drive assembly 244 to push the blade 01 to insert the blade.

[0082] In addition, the lower transmission track assembly 240 is provided with a lower pressure plate 203, which is correspondingly positioned above the lower transmission track 242. The lower pressure plate 203 is also mounted on a bracket, which is mounted on a transverse slide rail. The lower pressure plate 203 can be driven to move in the X direction by a driving component.

[0083] During the process of the blade 01 moving from the upper transmission track 232 to the lower transmission track 242, the lower pressure plate 203 avoids the upper transmission track 232. After the blade 01 has been transferred to the lower transmission track 242, the lower pressure plate 203 is driven to move laterally by the driving component and moves above the lower transmission track 242.

[0084] Continue as Figure 6 As shown, the robot arm 243 is flat and there is a gap between the lower transmission track 242 and the lower pressure plate 203 required for the robot arm 243 to move; at the same time, the robot arm 243 has a protrusion protruding from the lower transmission track 242 to push the blade 01 to move.

[0085] When the robot arm 243 moves, it moves in the Y direction, pushing the blade 01 to the blade insertion station.

[0086] like Figure 8 As shown, the blade insertion mechanism 300 has a movable positioning shaft assembly 310, an upper clamping assembly 320, a lower clamping assembly 330, and a blade positioning assembly 340; the positioning shaft assembly 310 moves between the blade insertion station and the riveting station to switch the position of the wind turbine; the upper clamping assembly 320 and the lower clamping assembly 330 are positioned vertically and vertically to position the fixing ring 02 of the wind turbine; the blade positioning assembly 340 supports the blade 01 during the blade insertion process.

[0087] Specifically, such as Figure 8 and Figure 11 As shown, the positioning shaft assembly 310 includes: a positioning shaft transmission component 311 and a positioning shaft 312; support arms 313 are respectively provided at both ends of the positioning shaft 312, one of the support arms 313 is mounted on the XY track 314, and the support arm 313 can disengage from the end of the positioning shaft 312 or connect to the end of the positioning shaft 312 when it moves along the XY track 314.

[0088] Here, the XY track 314 includes a transverse slide rail and a Y-direction slide rail, so that one of the support arms 313 can move in the X and Y directions, so that the end of the positioning shaft 312 is supported in one of the support arms 313 or moves away from one of the support arms 313.

[0089] The beginning of the positioning shaft 312 is mounted on another support arm 313 and can rotate. The beginning of the positioning shaft 312 is provided with a second gear 3121, which meshes with the first gear 3111 of the positioning shaft transmission component 311 to drive the positioning shaft 312 to rotate.

[0090] Both support arms 313 are mounted on a panel 315, which is mounted on a transverse slide rail to drive the positioning shaft 312 to move between the insert station and the riveting station, while simultaneously engaging or disengaging the first gear 3111 and the second gear 3121.

[0091] like Figure 2 As shown, the insert station and the riveting station are distributed in the X direction. Therefore, when the positioning shaft assembly 310 moves, it moves in the X direction to complete the switching of the impeller between different stations.

[0092] like Figure 8 As shown, the positioning shaft transmission component 311 is fixed in a stationary position, while the panel 315 drives the support arm 313 and the positioning shaft 312 to move in the X direction. Figure 8 The middle support arm 313 and the positioning shaft 312 have already been moved to the riveting station;

[0093] When the support arm 313 and the positioning shaft 312 are in the inserting station, the positioning shaft 312 should be positioned between the upper clamping assembly 320 and the lower clamping assembly 330.

[0094] like Figure 11 As shown, when installing the fixing ring 02, the fixing ring 02 can be manually placed on the positioning shaft 312. After the fixing ring 02 is assembled, the right support arm 313 moves on the XY track 314 until the right end of the positioning shaft 312 is inserted into the right support arm 313, so that both ends of the positioning shaft 312 are supported by the support arm 313.

[0095] When the positioning shaft 312 is in the inserting station, the second gear 3121 of the positioning shaft 312 meshes with the first gear 3111 of the positioning shaft transmission component 311, and the positioning shaft transmission component 311 drives the positioning shaft 312 to rotate.

[0096] When the positioning shaft 312 is in the riveting station, the second gear 3121 of the positioning shaft 312 and the first gear 3111 of the positioning shaft transmission component 311 are separated.

[0097] like Figure 8 As shown, the upper clamping assembly 320 and the lower clamping assembly 330 are respectively provided with a plurality of arc-shaped clamping blocks 321 and 331. The number of clamping blocks 321 and 331 is the same as the number of fixing rings 02 installed on the positioning shaft 312. The upper and lower corresponding clamping blocks 321 and 331 form a group, which positions the fixing rings 02 in the vertical direction.

[0098] The clamping block 321 of the upper clamping assembly 320 and the clamping block 331 of the lower clamping assembly 330 are respectively mounted on a support plate, and the support plate is mounted on a longitudinal slide rail. The support plate can be driven to move along the longitudinal slide rail by a driving component, so that the clamping block 321 of the upper clamping assembly 320 and the clamping block 331 of the lower clamping assembly 330 move closer or further apart.

[0099] like Figure 2 As shown, the insert mechanism 300 is located on the right side of the lower transfer track assembly 240. When the robot arm 243 moves in the Y direction, it pushes the blade 01 into the insert hole of the fixing ring 02, thus completing the assembly of the blade 01 and the fixing ring 02.

[0100] Once a blade 01 is inserted, the positioning shaft transmission component 311 drives the positioning shaft 312 to rotate by one displacement, waiting for the next blade insertion action, until all blades are inserted.

[0101] like Figure 9 and Figure 10As shown, the blade positioning assembly 340 includes: a positioning plate 341 and a positioning rail 342 mounted on the positioning plate 341. The positioning rail 342 is provided with a notch 343 to avoid the fixing ring. The positioning plate 341 is mounted on the transverse slide rail and moves towards or away from the upper clamping assembly 320 and the lower clamping assembly 330. When the lower transmission rail assembly 240 pushes the blade towards the fixing ring for insertion, the blade is supported on the positioning rail 342.

[0102] Before the inserting action is performed, the positioning plate 341 is driven by the drive component to move along the transverse slide rail. The movement stops the inserting station. During the process of inserting the blade 01 into the fixing ring 02, the positioning rail 342 can support the blade 01 to prevent the blade 01 from slightly shifting downward under the action of gravity, which would cause the blade 01 to fail to align with the hole on the fixing ring 02 during the inserting process.

[0103] After the blade insertion is completed, the upper clamping assembly 320 moves upward and the lower clamping assembly 330 moves downward, releasing the fixing ring 02; the blade positioning assembly 340 resets; then the positioning shaft 312 moves in the X direction, from the blade insertion station to the riveting station.

[0104] like Figure 12 As shown, the riveting mechanism 400 has multiple sets of riveting rollers 410, a drive plate 420, a first drive assembly 430, a second drive assembly 440, and a riveting bracket 450. The drive plate 420 is provided with an arc-shaped track groove 421. At least one set of riveting rollers 410 has both ends respectively limited within the track groove 421 and can move within the track groove 421. The first drive assembly 430 drives the drive plate 420 to move, thereby driving the riveting rollers 410 to move in the track groove 421. The second drive assembly 440 drives the riveting rollers 410 to rotate to perform the riveting action.

[0105] The riveting bracket 450 is used as a carrier, mainly to provide support, supporting at least the multiple sets of riveting rollers 410 and the drive plate 420. The riveting bracket 450 is provided with a left support plate 451 and a right support plate 452 distributed from left to right. The multiple sets of riveting rollers 410 are installed between the left support plate 451 and the right support plate 452. In this embodiment, three sets of riveting rollers 410 are provided, arranged in a triangular pattern.

[0106] Continue as Figure 12 As shown, the left support plate 451 and the right support plate 452 are provided with support rods 460, which fix the position between the left support plate 451 and the right support plate 452.

[0107] Three sets of riveting rollers 410 are installed parallel to each other on the riveting bracket 450. Each set of riveting rollers 410 is fitted with a riveting head 411. The two ends of the riveting rollers 410 pass through the left support plate 451 and the right support plate 452 respectively. When the large flow impeller is riveted, it is located between the three sets of riveting rollers 410, and the large flow impeller is riveted by the riveting rollers 410.

[0108] The drive plate 420 is installed on the outside of the left support plate 451 and the right support plate 452. The two ends of the riveting roller 410 pass through the left support plate 451 and the right support plate 452 and are connected to the drive plate 420. The drive plate 420 is provided with an arc-shaped track groove 421. The two ends of at least one set of riveting rollers 410 are respectively limited to the track groove 421 and can move within the track groove 421.

[0109] like Figure 14 As shown, in this embodiment, the three sets of riveting rollers 410 are all limited by the track grooves 421 on the drive plate 420, and the drive plate 420 is provided with track grooves 421 for each set of riveting rollers 410, and the three track grooves 421 are not connected.

[0110] In order for the riveting roller 410 to move normally along the track groove 421, the left support plate 451 and the right support plate 452 are respectively provided with clearance grooves. The clearance grooves avoid the riveting roller 410 so that it can move along the track groove 421; the clearance grooves and the track groove 421 partially overlap.

[0111] The first drive assembly 430 drives the drive plate 420 to move, thereby causing the riveting roller 410 to move in the track groove 421. When the first drive assembly 430 drives the drive plate 420 to move forward, the riveting roller 410 moves forward along the track groove 421, and multiple sets of riveting rollers 410 converge to clamp the impeller. When the first drive assembly 430 drives the drive plate 420 to move in the opposite direction, the multiple sets of riveting rollers 410 move in the opposite direction along the track groove 421, and the multiple sets of riveting rollers 410 move away from each other to release the impeller.

[0112] The second drive assembly 440 drives the riveting roller 410 to rotate in order to rivet the windmill.

[0113] In order to enable the riveting roller 410 to move smoothly in the track groove 421, rollers are provided at both ends of the riveting roller 410 to assist the riveting roller 410 in moving along the track groove 421.

[0114] In one embodiment, the drive plate 420 is provided with an arc-shaped rack 422, and the track groove 421 is arc-shaped; for example Figure 12 and Figure 14 As shown, the outer edge of the drive plate 420 is provided with an arc-shaped rack 422, and the first drive assembly 430 includes: a first motor 431 and a first meshing gear 432 that meshes with the arc-shaped rack 422;

[0115] The first motor 431 drives the first meshing gear 432 to rotate. Through the cooperation of the first meshing gear 432 and the arc rack 422, the drive plate 420 is driven to rotate. Then, with the cooperation of the clearance groove and the track groove 421, the riveting roller 410 moves. When moving, the three sets of riveting rollers 410 move closer to each other or further apart.

[0116] In addition, the first motor 431 can directly drive the first meshing gear 432 to rotate, or it can indirectly drive the first meshing gear 432 to rotate.

[0117] In order to achieve synchronous movement of both ends of the riveting roller 410, two first motors 431 can be set up, each first motor 431 driving a first meshing gear 432, which in turn drives the riveting roller 200 to move.

[0118] It is also possible that, for example Figure 14 As shown, the first drive assembly 430 further includes a connecting rod 433, which is mounted on the riveting bracket 450 and parallel to the riveting roller 410. The two ends of the connecting rod 433 are respectively provided with the first meshing gear 432, and the drive plates 420 located at both ends of the riveting roller 410 respectively mesh with one of the first meshing gears 432, so that the two ends of the riveting roller 410 move synchronously.

[0119] Furthermore, the output shaft of the first motor 431 is equipped with a first transmission wheel 4311; the connecting rod 433 is equipped with a second transmission wheel 4331, and the first transmission wheel 4311 and the second transmission wheel 4331 mesh with each other.

[0120] In one implementation, such as Figure 13 As shown, the second drive assembly 440 includes: a second motor 441, a belt drive assembly 442, and multiple sets of oscillating gears 443; the second motor 441, the belt drive assembly 442, and the multiple sets of oscillating gears 443 drive the riveting roller 410 to rotate, and the oscillating gears 443 oscillate as the riveting roller 410 moves along the track groove 421.

[0121] The swing gear set 443 includes: a swing arm 4431 and a plurality of meshing transmission wheels 4432 disposed on the swing arm 4431, wherein one of the transmission wheels is fixed to one end of the riveting roller 410; one of the transmission wheels meshes with the transmission wheels 4432 of other swing gear sets 443, or one of the transmission wheels meshes with a gear on the belt drive set 442 to realize transmission.

[0122] Specifically, such as Figure 13As shown, the belt drive assembly 442 includes two drive wheels and a belt wound around the drive wheels. The second motor 441 drives the belt drive assembly 442 to run. Multiple sets of oscillating gear sets 443 mesh with each other, and at least one set of oscillating gear sets 443 is connected to the belt drive assembly 442 and drives it, ultimately driving the riveting roller 410 to rotate.

[0123] In one embodiment, the riveting roller 410 further includes a rod 412 on which riveting heads 411 are evenly distributed. The number of riveting heads 411 and the spacing between multiple riveting heads 411 are determined according to the number of fixing rings 02 that need to be riveted on the large-scale flow impeller.

[0124] The large-scale flow impeller includes multiple blades 01 and a fixing ring 02 that connects the multiple blades 01. The fixing ring 02 is annular, and the blades 01 are inserted into the fixing ring 02. The number of rivet heads 411 and the spacing between the multiple rivet heads 411 are set according to the number of fixing rings on the large-scale flow impeller.

[0125] In this invention, during the riveting process, the three sets of riveting rollers 410 are far apart. The positioning shaft 312 drives the impeller that has already had its inserts inserted into the space between the three sets of riveting rollers 410. Then, the first drive assembly 430 runs forward, and the first motor 431 drives the connecting rod 433 to rotate, which in turn drives the first meshing gear 432 to rotate, thereby driving the drive plate 420 to rotate. During the rotation, the three sets of riveting rollers 410 move closer together to clamp the large flow impeller.

[0126] Then, the second drive assembly 440 operates, driving the three sets of riveting rollers 410 to rotate. During the rotation, the riveting head 411 performs a riveting operation between the fixed ring 02 and the blade 01.

[0127] Finally, after the riveting is completed, the second drive assembly 440 stops running, and the first drive assembly 430 runs in reverse to drive the drive plate 420 to move in the opposite direction, so that the three sets of riveting rollers 410 move away from each other, loosen the large flow impeller after riveting, and then take out the large flow impeller.

[0128] After the riveting is completed, one of the support arms 313 moves in the X and Y directions, so that the end of the positioning shaft 312 leaves one of the support arms 313. The large flow impeller can be taken out manually. After taking it out, the fixing ring 02 required for the next assembly is installed. Then, one of the support arms 313 is reset, and the entire positioning shaft 312 is reset and moved to the insert station to prepare for processing and assembling the next large flow impeller.
