Description

[0002] The lamination processing of wind turbines usually refers to the lamination of the stator core to form the stator core. When laminating, the laminations are placed on the lamination tooling in a certain order and direction to ensure that the gaps between the laminations are uniform, and then the laminations are pressed using a clamping device to keep them in a tightly stacked state.

[0003] However, in the prior art, when stacking wind turbine generators, multiple robotic arms are required to perform collaborative operations. Since the structure of the robotic arms is complex, involving multiple driving components, and there are differences in the motion control accuracy between different robotic arms, inconsistencies in coordination are likely to occur during the collaborative work process. As the number of robotic arms increases, the communication system between the robotic arms will fail or be disturbed. Each robotic arm has a certain accuracy error.

[0015] A method for using a circular conveying device for automatically stacking motor sector pieces comprises the following steps:

[0016] Step 1: Loading and pushing. The fan-shaped pieces are transported from the loading machine to the ring conveyor. The eight first cylinders work in sequence. After completing a cycle, they run in a cycle to push and stack the fan-shaped pieces one by one.

[0017] Step 2: Transfer the fan-shaped pieces. The driving mechanism controls the transfer mechanism to run a cycle, removes the fan-shaped pieces on the stacking plate and transfers them to the installation position;

[0018] Step 3: Stacking and resetting: the second driving motor drives the coupling rod to rotate through the worm and the worm gear, so that the belt transmission part transmits power to the first crank, drives the first push block and the swing rod to swing, further drives the second crank and the third movable rod to rotate, drives the sliding sleeve to move and adjusts the position of the electric clamp;

[0019] Step 4: Change the stacking station. The first drive motor rotates the gear, and the gear interacts with the gear ring to push the moving block. The movement of the moving block causes the guide block to slide in the slide groove and drives the second mounting frame to run stably under the restriction of the inner ring so as to adjust the position and prepare to stack the next sector.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the fan-shaped pieces are transported to the ring conveyor by the loader, and the first cylinder pushes the fan-shaped pieces to the guide plate. The equipped sensor monitors the position of the fan-shaped pieces in real time to ensure accurate pushing of the materials. The eight cylinders operate in sequence to achieve sequential stacking and maintain continuous and efficient operation. After the fan-shaped pieces are pushed to the stacking plate, the driving mechanism and the transfer mechanism control the clamp to transfer. The image sensor on the electric clamp monitors the state of the fan-shaped pieces and automatically adjusts the angle of the clamp to ensure the correct direction before installation. After the clamping is completed, the second cylinder controls the up and down movement, and the electric clamp accurately installs the fan-shaped pieces. The guide plate ensures stable transmission, and the raised structure of the stacking plate prevents slipping and improves safety. After successful stacking, the first drive motor starts to drive the gear and the moving block to slide, ensuring that the moving process is stable and accurate. The design of the inner ring enhances the stability of the second mounting frame. The entire system efficiently integrates various links to ensure accurate and smooth stacking of the fan-shaped pieces.

[0022] 2. In the present invention, during the stacking process, the second cylinder controls the up and down movement of the top plate, and the key components in the drive system interact with each other to achieve coordinated work. The movement of the top plate pushes the first movable rod, and drives the first limit block through sliding, compresses the first spring, stores potential energy, and provides stable power support for subsequent resetting. The second drive motor starts the worm, and the worm engages with the worm wheel to transmit power to the coupling rod, which transmits power to the transfer mechanism through a belt drive, so that the two movable frames move synchronously, effectively controlling the electric clamp to clamp and release the fan-shaped piece. The design of the entire power transmission system ensures accurate and stable operation. The self-locking function of the worm and the worm wheel prevents reverse movement, thereby improving the safety and efficiency of the system.

[0023] 3. In the present invention, the belt transmission part transmits power to the first crank, starting the mechanical coordination work. The rotation of the first crank drives the first push block to slide, and exerts a force on the swing rod, further pushing the rotating rod, so that the second crank rotates. The self-steering of the second push block exerts additional force on the third movable rod, pushing the movable frame to move, and smoothly slides along the sliding rod through the sliding sleeve to achieve precise positioning and operation. The second spring and the second limit block in the system ensure that the movable frame moves within a safe range. When the first crank completes one circle of rotation, the second crank rotates in the opposite direction to gradually reset the sliding sleeve, and prepare the electric clamp to transfer the fan-shaped piece. The entire transfer process runs according to the set cycle to ensure high precision and consistency, reduce human intervention and operation errors. This design not only improves the stability and operational reliability of the system, but also provides effective guarantee for mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Reference Figure 1 - Figure 5 As shown: an automatic stacking annular conveying device for motor fan-shaped pieces, comprising a feeder 1 and a first support frame 3, an annular conveyor 2 is installed on the top of the first support frame 3, a plurality of first cylinders 4 are installed on the outer edge of the top of the annular conveyor 2, a push plate 41 is fixedly connected to the output end of the first cylinder 4, a guide plate 6 is installed on the inner side of the annular conveyor 2, a rotating mechanism 7 is installed on the inner side of the guide plate 6, and a stacking plate 61 is fixedly connected to the bottom end of the guide plate 6;

[0036] The rotating mechanism 7 includes a base plate 71 and a second mounting frame 77. A slide groove 711 is provided on the top of the base plate 71. A guide block 741 is slidably connected to the inner side of the slide groove 711. A moving block 74 is fixedly connected to the top of the guide block 741. The moving block 74 is fixedly connected to the bottom end of the second mounting frame 77. Two second cylinders 78 are symmetrically fixedly connected to the top of the second mounting frame 77. A driving mechanism 8 is installed on the inner side of the second mounting frame 77. A transfer mechanism 9 is installed below the driving mechanism 8. The transfer mechanism 9 is used to transfer the fan-shaped piece to the mold. The driving mechanism 8 is used to drive the transfer mechanism 9 to operate. The outer top end of the moving block 74 is fixedly connected to the first mounting frame 751. The inner side of the first mounting frame 751 is rotatably connected to the gear 75.

[0037] In this embodiment, the fan-shaped pieces are conveyed to the ring conveyor 2 by the feeder 1. As the fan-shaped pieces rotate on the ring conveyor 2, the first cylinder 4 is responsible for pushing the fan-shaped pieces from the pile to the guide plate 6. Sensors are installed on the side walls of each push plate 41. These sensors can monitor the position information of the fan-shaped pieces in real time to ensure accurate pushing operation after the fan-shaped pieces reach the specified position. The entire system is equipped with eight first cylinders 4, which operate in sequence to ensure that the fan-shaped pieces can be stacked one by one in order. After the operation of each cylinder is completed, the system automatically starts the next cylinder in a cycle to ensure the continuity and efficiency of the entire stacking process.

[0038] After the fan-shaped pieces are pushed onto the stacking plate 61 for stacking, the drive mechanism 8 is started to control the transfer mechanism 9 to transfer the stacked fan-shaped pieces to the installation position. At this time, the electric clamp 5 plays a vital role in the transfer process. Through the clamping operation of the fan-shaped pieces, it is ensured that they can be taken away safely and stably. During the clamping process, the image sensor installed on the electric clamp 5 monitors the state of the fan-shaped pieces in real time, especially its installation angle. If the angle of the fan-shaped piece is detected to be incorrect, the system will automatically adjust the rotation angle of the electric clamp 5 to ensure that the direction is corrected before installation.

[0039] After the sector pieces are clamped, the system enters the stacking operation. The second cylinder 78 controls the up and down movement of the drive mechanism 8 and the transfer mechanism 9 to ensure that the electric clamp 5 can accurately install the sector pieces to the specified position. During this process, the guide plate 6 on the inner side of the ring conveyor 2 is responsible for guiding the transmission of the sector pieces in turn to ensure its stability during the installation process. The outer surface of the stacking plate 61 is designed with a protrusion structure, which can effectively prevent the sector pieces from slipping during the transmission or installation process, further ensuring the safety and smoothness of the operation.

[0040] After each successful stacking of a sector, the system enters the next operation stage. At this time, the first drive motor 76 is started, and by driving the gear 75 to rotate, a force is generated between the gear 75 and the gear ring 721. This force causes the moving block 74 to begin to move under the sliding action of the guide block 741, and the slider slides stably on the inner side of the slide groove 711, ensuring the stability and position accuracy of the entire moving process. At the same time, the restriction design of the inner ring 73 further ensures the stability and accuracy of the second mounting frame 77 during movement. As the moving block 74 moves, the second mounting frame 77 also moves accordingly. After adjusting the position, the system is ready to stack the next sector.

[0041] Embodiment 2: Figure 4 - Figure 6As shown, the driving mechanism 8 includes a top plate 81, and two second support frames 86 are symmetrically fixedly connected to the top of the top plate 81. The two second support frames 86 are rotatably connected to the inner sides of the coupling rods 83. A worm wheel 831 is fixedly connected to the outer surface of the middle part of the coupling rod 83, and a worm 84 is meshedly connected below the worm wheel 831. A second driving motor 82 is installed on one side of the top of the top plate 81. The output end of the second driving motor 82 is fixedly connected to the worm 84, and both ends of the coupling rod 83 are fixedly connected to the belt transmission member 85. The top of the top plate 81 is fixedly connected to the bottom ends of the two second cylinders 78, and the top of the top plate 81 is fixedly connected to the first movable rod 79. The top end of the first movable rod 79 passes through the second mounting frame 77, and the first movable rod 79 is slidably connected to the second mounting frame 77. The top of the first movable rod 79 is fixedly connected to the first limit block 792, and a first spring 791 is installed between the first limit block 792 and the second mounting frame 77. The first spring 791 is sleeved on the outer surface of the first movable rod 79. An inner ring 73 is fixedly connected to the inner side of the bottom of the stacking plate 61, and an outer ring 72 is fixedly connected to the outer side of the bottom of the stacking plate 61. A gear ring 721 is fixedly connected to the inner side of the outer ring 72. The gear ring 721 is meshed with the gear 75. A gear 75 is fixedly installed on the side wall of the moving block 74. The output end of the gear 75 is fixedly connected to the first mounting frame 751.

[0042] In this embodiment, during the stacking process, the second cylinder 78 drives the key components in the system to interact with each other by controlling the up and down movement of the top plate 81. The up and down movement of the top plate 81 not only drives the top plate 81 itself, but also drives the movement of the first movable rod 79. When the first movable rod 79 slides relative to the second mounting frame 77.

[0043] When the first movable rod 79 slides, it drives the first limit block 792 connected thereto to move together. At this time, the first limit block 792 squeezes the first spring 791 installed on the outer surface of the first movable rod 79. As the first spring 791 is compressed, the first spring 791 gradually accumulates potential energy, providing stable power support for subsequent resetting. It not only provides a smooth guiding function, but also helps each component to be smoothly reset after the stacking operation is completed, thereby ensuring the smoothness and stability of the entire operation process.

[0044] The second drive motor 82 starts to drive the worm 84 to rotate. As the worm 84 rotates, the worm 84 meshes with the worm wheel 831, transmitting power to the worm wheel 831. When the worm wheel 831 rotates, the force is transmitted to the coupling rod 83, so that the coupling rod 83 performs stable rotational motion under the support of the second support frame 86. The rotation of the coupling rod 83 transmits power to the transfer mechanism 9 through two belt transmission members 85, so that the two movable frames 93 in the transfer mechanism 9 move synchronously.

[0045] The two movable frames 93 coordinately control the movement of the electric clamp 5, which is responsible for clamping and releasing the fan-shaped pieces. The operation of the clamp is precise and stable, and it can effectively clamp the fan-shaped pieces during the stacking process and release the fan-shaped pieces when needed. The entire power transmission system is through the action of the worm 84 and worm wheel 831 structure, and then the coupling rod 83 and the belt transmission member 85 transmit the power step by step, making the whole process both precise and stable. The design of the worm 84 and the worm wheel 831 can not only provide sufficient torque, but also have a good self-locking function to prevent reverse movement, further ensuring the safety of operation.

[0046] Embodiment 3: According to Figure 7 - Fig. 9 As shown, the transfer mechanism 9 includes a frame 91, a sliding rod 911 is fixedly connected to the inner side of the top of the frame 91, a sliding sleeve 92 is slidably connected to the outer surface of the sliding rod 911, a second movable rod 921 is fixedly connected to the bottom end of the sliding sleeve 92, a second limit block 922 is fixedly connected to the bottom end of the second movable rod 921, a movable frame 93 is slidably connected to the outer surface of the second movable rod 921, an electric clamp 5 is fixedly connected to the bottom end of the movable frame 93, a connecting frame 98 is rotatably connected to the side wall of the top end of the movable frame 93, a third movable rod 96 is fixedly connected to the bottom end of the connecting frame 98, and a second spring 99 is slidably connected to the outer surface of the third movable rod 96. A swing rod 95 is rotatably connected to the bottom end of the frame 91, a first driving hole 951 is opened in the middle of the swing rod 95, and a second driving hole 952 is opened in the top end of the swing rod 95, a first crank 94 is rotatably connected to the middle of the frame 91, and the first crank 94 is fixedly connected to the output end of the belt transmission member 85. One end of the first crank 94 is rotatably connected to a first push block 941, a side wall of the third movable rod 96 is fixedly connected to a second push block 972, one end of the second push block 972 is fixedly connected to a second crank 97, one end of the second crank 97 is rotatably connected to a rotating rod 971, and the second crank 97 is rotatably connected to the frame 91. The first push block 941 is slidably connected to the first driving hole 951, the rotating rod 971 is slidably connected to the second driving hole 952, a second spring 99 is provided between the third movable rod 96 and the connecting frame 98, and the second spring 99 is sleeved on the outer surface of the third movable rod 96.

[0047] In this embodiment, in the whole system, the belt transmission member 85 starts the coordinated work of the machinery by transmitting power to the first crank 94. When the first crank 94 rotates, it drives the first push block 941 connected thereto. At this time, the first push block 941 slides in the first drive hole 951 and applies a force to the swing rod 95, causing the swing rod 95 to start swinging. During the swinging process of the swing rod 95, it further applies a force to the rotating rod 971, driving the rotating rod 971 to move, and the movement of the rotating rod 971 is transmitted to the second crank 97, causing the second crank 97 to start rotating, thereby driving the second push block 972 to rotate synchronously.

[0048] As the second push block 972 rotates, it applies an additional force to the third movable rod 96. Under the action of the connecting frame 98, the third movable rod 96 transmits this force to the movable frame 93, pushing the movable frame 93 to start moving. At the same time, the contact between the sliding sleeve 92 and the outer surface of the sliding rod 911 allows the sliding sleeve 92 to slide smoothly along the sliding rod 911. This sliding motion ultimately guides the position adjustment of the movable frame 93, making it easier for the electric clamp 5 to clamp the next fan-shaped piece, and achieving precise positioning and operation.

[0049] When the sliding sleeve 92 slides along the outer surface of the sliding rod 911 and hits the frame 91, if the third movable rod 96 continues to swing, the third movable rod 96 will contact and squeeze the second spring 99 on the outer surface, causing the second spring 99 to be compressed. At the same time, the movable frame 93 begins to slide up and down along the surface of the second movable rod 921 to adjust its position relative to the overall mechanical structure. In order to prevent the movable frame 93 from being separated from the second movable rod 921, the system introduces a second limit block 922, which limits the moving distance of the movable frame 93 and ensures that the movable frame 93 always remains within a safe working range.

[0050] Since the first crank 94 and the second crank 97 have different rotation radii, their rotation rhythms are also different. When the first crank 94 completes a full circle of rotation, the second crank 97 begins to rotate in the opposite direction. This reverse rotation action causes the sliding sleeve 92 to gradually begin to reset, preparing for subsequent operations. This reset mechanism can restore the initial position of the electric clamp 5 to a suitable state, making it convenient to accurately transfer the clamped fan-shaped piece to the top of the mold, ensuring that the next step of assembly or operation proceeds smoothly.

[0051] During the transfer process of the fan-shaped pieces, the transfer mechanism 9 operates according to the set cycle. Through a complete cycle action, the system can accurately and smoothly transfer the fan-shaped pieces from the storage position to the installation position. Since the entire operation process is strictly carried out according to the set mechanical rhythm and motion trajectory, the errors that occur after multiple transfers are avoided, ensuring the high accuracy and consistency of the transfer. This design ensures the stability of the system and the reliability of operation, especially in environments that require mass production or continuous work, and can effectively reduce human intervention and operation errors.

[0052] A method for using a circular conveying device for automatically stacking motor sector pieces comprises the following steps:

[0053] 1) Loading and pushing materials. The sector pieces are transported from the loading machine 1 to the ring conveyor 2. The eight first cylinders 4 work in sequence. After completing one cycle, they run in a cycle to push and stack the sector pieces one by one.

[0054] 2) Transferring the sector-shaped pieces, the driving mechanism 8 controls the transfer mechanism 9 to run a cycle, removes the sector-shaped pieces on the stacking plate 61 and transfers them to the installation position;

[0055] 3) Stacking and resetting, the second driving motor 82 drives the coupling rod 83 to rotate through the worm 84 and the worm wheel 831, so that the belt transmission member 85 transmits power to the first crank 94, drives the first push block 941 and the swing rod 95 to swing, further drives the second crank 97 and the third movable rod 96 to rotate, drives the sliding sleeve 92 to move and adjust the position of the electric clamp 5;

[0056] 4) Change the stacking station, the first drive motor 76 rotates the gear 75, the gear 75 interacts with the gear ring 721, and pushes the moving block 74. The movement of the moving block 74 causes the guide block 741 to slide in the slide groove 711, and drives the second mounting frame 77 to run stably under the restriction of the inner ring 73, so as to adjust the position and prepare for stacking the next sector.

[0057] The use method and working principle of the device are as follows: the fan-shaped pieces are conveyed to the ring conveyor 2 through the feeder 1. As the fan-shaped pieces rotate on the ring conveyor 2, the first cylinder 4 is used to control the push plate 41 to push the fan-shaped pieces to the guide plate 6. A sensor is installed on the side wall of each push plate 41 to detect that the fan-shaped pieces are in place and then push the pieces. In addition, the eight first cylinders 4 operate in sequence, and after completing a cycle, they run in a cycle to complete the stacking of the fan-shaped pieces one by one.

[0058] After the fan-shaped pieces are moved to the stacking plate 61 and stacked, the driving mechanism 8 controls the transfer mechanism 9, and the transfer mechanism 9 runs a cycle to remove the fan-shaped pieces on the stacking plate 61 and move them to the installation position. During the transfer process, the electric clamp 5 clamps the fan-shaped pieces. When clamping, the image sensor on the electric clamp 5 detects whether the installation direction of the fan-shaped pieces is correct. If the angle is incorrect, the electric clamp 5 will rotate and adjust.

[0059] During stacking, the second cylinder 78 controls the top plate 81 to move up and down, and the top plate 81 drives the first movable rod 79 to move, and the first movable rod 79 slides relative to the second mounting frame 77. As the first movable rod 79 slides, the first limit block 792 also moves, and the first limit block 792 squeezes the first spring 791 to compress it, which plays a role of guiding and resetting, ensuring the stability of the stacking process.

[0060] During the stacking process, the second driving motor 82 drives the worm 84 to rotate, the worm 84 rotates to drive the worm wheel 831, and the worm wheel 831 drives the coupling rod 83 to rotate, and the coupling rod 83 operates under the support of the second support frame 86. The belt transmission member 85 transmits power to the first crank 94, and the first crank 94 drives the first push block 941 to rotate. When the push block slides in the first driving hole 951, it applies a force to the swing rod 95, pushing the swing rod 95 to swing. During the swinging process, the swing rod 95 acts on the rotating rod 971, and the rotating rod 971 transmits the force to the second crank 97, driving the second push block 972 to rotate.

[0061] When the second push block 972 rotates, a force is applied to the third movable rod 96, and the third movable rod 96 transmits the force to the movable frame 93 through the connecting frame 98. The movable frame 93 drives the sliding sleeve 92 to move, and the sliding sleeve 92 slides along the surface of the sliding rod 911, and finally adjusts the position of the electric clamp 5 to facilitate the clamping of the next sector.

[0062] When the sliding sleeve 92 slides to the frame 91, if the third movable rod 96 continues to swing, it will squeeze the second spring 99 to compress it, and the sliding sleeve 92 can no longer move, so that the movable frame 93 starts to slide up and down along the surface of the second movable rod 921. The second limit block 922 limits the moving distance of the movable frame 93 to prevent the movable frame 93 from being separated from the second movable rod 921.

[0063] Since the first crank 94 and the second crank 97 have different rotation radii, when the first crank 94 completes one circle, the second crank 97 will start to rotate in the opposite direction, driving the sliding sleeve 92 to reset, so as to facilitate the transfer of the clamped sector piece to the top of the mold.

[0064] During the transfer process, the transfer mechanism 9 runs a complete cycle to transfer the sector from the storage position to the installation position to avoid errors after multiple transfers. Until the electric clamp 5 installs the sector to the specified position, the guide plate 6 on the inner side of the ring conveyor 2 guides the material in turn, and the protrusions on the surface of the stacking plate 61 prevent the sector from sliding off.

[0065] After stacking a sector, the first drive motor 76 drives the gear 75 to rotate, and the gear 75 and the gear ring 721 generate a force to push the moving block 74 to move. The movement of the moving block 74 causes the guide block 741 to slide inside the slide groove 711, and at the same time, the moving block 74 drives the second mounting frame 77 to run stably under the restriction of the inner ring 73, so as to adjust the position and prepare for stacking the next sector.

[0066] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
