Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and specifically to a gear core feeding and conveying device. Background Technology

[0002] The stator core is a crucial component of the motor's magnetic circuit. Together with the rotor core and the air gap between the stator and rotor, it forms the complete magnetic circuit of the motor. Currently, the assembly process for stator windings is separate and not integrated into a single unit. For gear cores, frequent manual transfer is required to move the core to the next stage. Furthermore, gear core loading typically involves only one manual loading point with limited storage capacity, making it inconvenient and reducing the stator winding assembly speed. The manual transfer process also generates a significant amount of waste material, leading to high production costs. Summary of the Invention

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0036] Reference Figure 1-4 As shown, a gear core feeding and conveying device includes:

[0037] Feeding turntable 1 is mounted on base 11;

[0038] A drive component is disposed on the base 11 and located below the feeding turntable 1, for driving the feeding turntable 1 to rotate;

[0039] The feeding assembly 3 is set on the feeding turntable 1 and is used to position and convey the stacked gear cores 54 one by one;

[0040] The feeding component 4 is located above the loading component 3 and is used to grab and transport the gear core 54 on the loading component 3.

[0041] Positioning component 6 is located on one side of the feeding turntable 1. The feeding component 4 transports the gear core 54 to the positioning component 6 for positioning.

[0042] The drive component drives the feeding component 3 on the feeding turntable 1 to move to the feeding station. The feeding component 3 lifts the topmost gear core 54 of the stacked gear cores 54, so that it is detached from the feeding component 3. Then, the feeding component 4 moves above the gear core 54, grabs the gear core 54 and transports it to the positioning component 6 for positioning.

[0043] This invention employs a drive assembly to rotate the feeding turntable 1 to transport gear cores 54. The loading assembly 3 lifts the topmost gear core 54 from the stack, detaching it from the loading assembly 3. The feeding assembly 4 then moves above the gear core 54, grabs it, and transports it to the positioning assembly 6 for positioning. The precise positioning of the feeding turntable 1 improves the conveying rate of the gear cores 54, thereby increasing the output of gear cores 54. Simultaneously, the loading assembly 3 positions and transports the stacked gear cores 54 one by one, preventing accidental movement of the gear cores 54 during loading and reducing scratches caused by conveying friction.

[0044] Reference Figure 3 As shown, the feeding assembly 3 includes:

[0045] The feeding fixture is set on the edge of the feeding turntable 1;

[0046] The lifting frame 2 is located below the feeding turntable 1. The lifting frame 2 is equipped with two support rods 21, which form a lifting position for the movement of the gear core 54.

[0047] The lifting component is driven to be connected to the lifting frame 2. The lifting component drives the two support rods 21 on the lifting frame 2 to lift the gear core 54.

[0048] The distance between the two support rods 21 is slightly smaller than the diameter of the gear core 54, so that the two support rods 21 support the edge of the gear core 54.

[0049] Specifically, the lifting component drives the two support rods 21 on the lifting frame 2 to lift the gear core 54. The distance between the two support rods 21 is smaller than the diameter of the gear core 54, which can facilitate the lifting station to lift the stacked gear cores 54 as a whole, ensure the stability of the lifting process, and position the gear core 54 to the predetermined position.

[0050] Furthermore, the feeding fixture includes a fixed plate 22, which is detachably connected to the feeding turntable 1 by fixing bolts. The fixed plate 22 is provided with a clearance groove 25 that matches the support rod 21. A fixed block 23 is provided on the fixed station formed by the two clearance grooves 25. A vertical rod 24 for stacking and placing the gear core 54 is provided on the fixed block 23. The lifting component drives the support rod 21 to pass through the clearance groove 25 and lift the gear core 54 on the vertical rod 24.

[0051] Specifically, the vertical rod 24 passes through the center of the gear core 54 to stack the gear core 54. The vertical rod 24 can balance, support and stack the gear core 54, and prevent the feeding turntable 1 from tilting after feeding, which would cause the feeding to be uneven.

[0052] Furthermore, the lifting component includes a lifting bracket 31, a lifting driver 32 is provided on the lifting bracket 31, a connecting plate 33 is provided on the lifting driver 32, the lifting frame 2 is provided on the connecting plate 33, the edge of the feeding turntable 1 is provided with a guide groove 26 that matches the support rod 21, and the lifting driver 32 drives the support rod 21 to pass through the guide groove 26 and lift the gear core 54.

[0053] Specifically, the lifting driver 32 drives the two support rods 21 on the lifting frame 2 to pass through the guide groove 26 and the clearance groove 25 on the fixing plate 22 in sequence, and then abuts against the gear core 54 located at the bottom of the vertical rod 24. The lifting driver 32 continues to push the stacked gear core 54 upward, and the gear core 54 moves upward along the vertical rod 24 until the gear core 54 located at the top of the stacked gear core 54 is separated from the vertical rod 24, making the rising process of the gear core 54 more stable and balanced, and the rising height is fixed with small rising error, ensuring that the gear core 54 is positioned in the predetermined position, which is convenient for the feeding component 4 to pick up the material from the predetermined position.

[0054] Furthermore, the positioning component 6 includes a positioning seat 61 and a conveying driver 63 disposed above the positioning seat 61. The positioning seat 61 is provided with a positioning groove 62 for placing the gear core 54. The conveying driver 63 is drivenly connected to the conveying gripper 64. The conveying driver 63 drives the conveying gripper 64 to convey the positioned gear core 54 to the next process. The conveying gripper 64 has the same structure as the feeding gripper 5.

[0055] Specifically, the lifting driver 43 drives the three-jaw cylinder 51 to move downwards and place the gear core 54 in the positioning groove 62 for stator winding assembly. The conveying driver 63 drives the conveying jaws 64 to transport the assembled gear core 54 to the next process, which greatly improves the manufacturing efficiency and precision of the stator winding, reduces production costs, and reduces the number of processes.

[0056] Furthermore, the drive assembly includes a speed reducer 12, which is drivenly connected to the rotary table. The base 11 is disposed on the rotation surface of the rotary table. The speed reducer 12 is drivenly connected to a drive motor 13, which drives the speed reducer 12 to rotate the base 11 on the rotary table.

[0057] Specifically, the gear cores 54 are loaded one by one onto the vertical rod 24, forming a stack of gear cores 54 on the vertical rod 24 of the feeding assembly 3. The drive motor 13 drives the reducer 12 to drive the base 11 to rotate on the rotary table, and the vertical rod 24 loaded with gear cores 54 is transported to the feeding assembly 4. The drive motor 13 drives the reducer 12 to drive the base 11 to rotate on the rotary table, which makes it easy to stop the rotation at a certain time. The overall structure design is simple and reasonable, with strong stability and long service life.

[0058] Further, the feeding assembly 4 includes:

[0059] A feeding driver 42 is mounted on a feeding rack 41 and is connected to the conveyor rack in a driving connection.

[0060] A lifting driver 43 is disposed on the conveyor frame, and the lifting driver 43 is drivenly connected to the drive frame;

[0061] The feeding gripper 5 is mounted on the drive frame. The feeding driver 42 and the lifting driver 43 drive the feeding gripper 5 to grip the gear core 54 on the feeding assembly 3.

[0062] Specifically, the feeding driver 42 drives the feeding gripper 5 to move above the vertical rod 24 on which the gear core 54 is loaded, until the gear core 54 at the top of the stacked gear cores 54 is detached from the vertical rod 24. At the same time, the lifting driver 43 drives the three-jaw cylinder 51 to move downward. The three-jaw cylinder 51 drives the clamping block 52 to stably clamp the gear core 54. The clamping groove 53 is engaged on the teeth, and the clamping plate can be inserted between adjacent teeth on the gear core 54 to improve the stability of production. Its overall structure is compact and occupies a small area.

[0063] Reference Figure 2 As shown, the feeding assembly 4 further includes an adjustment component, which includes a top plate 7. A first plate 71 is provided on the top plate 7. The top plate 7 is drivenly connected to the drive frame. A first slider is provided on the first plate 71. The first slider is slidably disposed on a second plate 72. The sliding direction of the first slider is perpendicular to the sliding direction of the second slider. A second slider is provided on the bottom surface of the second plate 72. The second slider is slidably disposed on a bottom plate 73. The feeding gripper 5 is connected to the bottom plate 73.

[0064] Specifically, the first slider is slidably mounted on the second plate 72, and the sliding direction of the first slider is perpendicular to the sliding direction of the second slider. The second slider is mounted on the bottom surface of the second plate 72 and is slidably mounted on the base plate 73. The hand is fixed to the corresponding base plate 73, which avoids the base plate 73 from shaking and improves the performance. There is no need to adjust the position of the gear core 54, which reduces the action and time of repeatedly positioning the gear core 54.

[0065] Furthermore, the base plate 73 is provided with first support rods 74 on both sides, and a first magnet 75 is provided on the first support rods 74. A second magnet is provided on the second slider, which is opposite to the first magnet 75. The first magnet 75 and the second magnet have opposite magnetic properties. The top plate 7 is provided with second support rods 76 on both sides, and a third magnet 77 is provided on the second support rods 76. A fourth magnet is provided on the first slider, which is opposite to the third magnet 77. The third magnet 77 and the fourth magnet have opposite magnetic properties.

[0066] Reference Figure 4 As shown, specifically, the first magnet 75 has opposite magnetic properties to the second magnet, and the third magnet 77 has opposite magnetic properties to the fourth magnet. This allows the first slider and the second slider to have a certain amount of movement between the second support rod 76 and the first support rod 74, respectively. This creates a buffer zone between the first slider and the second support rod 76, and between the second slider and the first support rod 74. During conveyor belt operation, the buffering effect of the repulsive magnets reduces the vibration amplitude of the conveyor belt during transport. After being transported to the designated position, the opposite magnetic properties of the first magnet 75 and the second magnet, and the opposite magnetic properties of the third magnet 77 and the fourth magnet, ensure that the feeding gripper 5 is always at the center of the adjusting component. This completes the secondary positioning of the gear core 54 after transport, ensuring the fault tolerance of the feeding gripper 5 in placing the gear core 54 on the positioning component 6, and providing the positioning accuracy of the gear core 54.

[0067] Furthermore, the feeding gripper 5 includes a three-jaw cylinder 51, a clamping block 52 is provided on the clamping arm of the three-jaw cylinder 51, a clamping plate is provided on the clamping block 52, and a clamping groove 53 matching the shape of the gear core 54 is provided on the clamping plate. The clamping plate has a wedge-shaped structure, so that the clamping plate can be inserted between adjacent teeth on the gear core 54.

[0068] Specifically, the clamping plate is provided with a clamping groove 53 that matches the shape of the gear core 54. The three-jaw cylinder 51 drives the clamping block 52 to stably clamp the gear core 54, making the gear core 54 more stable during transportation. The protruding teeth of the gear core 54 are also blocked by the protrusion, which further ensures the clamping stability. At the same time, the wedge-shaped clamping plate can be inserted between adjacent teeth on the gear core 54, effectively avoiding the vibration amplitude during transportation, thereby ensuring the stable transportation of the gear core 54.

[0069] The feed driver 42, lifting driver 32, conveying driver 63, and other drivers can be driven by cylinders, electric cylinders, linear modules, etc., and can also be driven by multi-axis robots to facilitate rapid conveying of the gear.

[0070] Usage process:

[0071] The gear cores 54 are loaded one by one onto the vertical rod 24, forming a stack of gear cores 54 on the vertical rod 24 of the feeding assembly 3. The drive motor 13 drives the reducer 12 to drive the base 11 to rotate on the rotary table, and the vertical rod 24 loaded with gear cores 54 is transported to the feeding assembly 4.

[0072] The feeding driver 42 drives the feeding gripper 5 to move above the vertical rod 24 on which the gear core 54 is loaded;

[0073] The lifting driver 32 drives the two support rods 21 on the lifting frame 2 to pass through the guide groove 26 and the clearance groove 25 on the fixing plate 22 in sequence, and then abuts against the gear core 54 located at the bottom of the vertical rod 24. The lifting driver 32 continues to push the stacked gear core 54 upward. The gear core 54 moves upward along the vertical rod 24 until the gear core 54 located at the top of the stacked gear core 54 is separated from the vertical rod 24. At the same time, the lifting driver 43 drives the three-jaw cylinder 51 to move downward. The three-jaw cylinder 51 drives the clamping block 52 to stably clamp the gear core 54. The clamping groove 53 is locked on the teeth, and the clamping plate can be inserted between adjacent teeth on the gear core 54.

[0074] The feeding driver 42 drives the feeding gripper 5, which holds the gear core 54, to move to the positioning component 6. Under the action of the opposite magnetic properties of the first magnet 75 and the second magnet, and the opposite magnetic properties of the third magnet 77 and the fourth magnet, the feeding gripper 5 is always at the center of the adjusting component. After the secondary positioning of the gear core 54 is completed after feeding, the lifting driver 43 drives the three-jaw cylinder 51 to move downward and place the gear core 54 in the positioning groove 62 for stator winding assembly. The conveying driver 63 drives the conveying jaws 64 to convey the assembled gear core 54 to the next process.
