Description

[0002] The impeller of a generator set consists of two parts: a top cover and a base. These parts are typically welded together using ultrasonic welding equipment. Blades are installed inside both the top cover and the base. Before welding, the top cover and base must be assembled together, with the blades arranged in an alternating pattern. Currently, this assembly is usually done manually. This is problematic because the blades inside the top cover and base have thin, sharp edges, posing safety hazards and resulting in low assembly efficiency. Furthermore, the top cover and base are prone to loose assembly, or the blades may misalign, leading to unstable subsequent welding.

Moreover, this application should be understood not only through the actual terms used, but also through the meaning implied by each term.

[0035] According to some embodiments of this application, please refer to Figures 1 to 8 As shown, an impeller assembly device is provided, including a base plate 1 and a conveying mechanism, a driving mechanism, a detection mechanism, and a loading mechanism 5 disposed on the base plate 1. The conveying mechanism 1 is used to convey an upper cover 6 and a base 7. The detection mechanism is used to detect the upper cover blade 61 and the base blade 72 so that the upper cover blade 61 and the base blade 71 are angled and engaged. The driving mechanism includes a first motion module 2 and a second motion module 3. The first motion module 2 is used to grab the upper cover 6 and transfer it to the loading mechanism 5. The second motion module 3 is used to grab the base 7 and transfer it to the loading mechanism 5. By rotating, the base blade 71 and the upper cover blade 61 are clamped and assembled into an impeller for welding.

[0036] According to some embodiments of this application, the conveying mechanism 1 includes two conveying components, each of which includes a support 11, a vibratory feeder 12, and a feed channel 13. The feed channel 13 is disposed on the support 11, and the vibratory feeder 12 is connected to the feed channel 13. The vibratory feeder 12 drives the feed channel 13 to vibrate, so that the upper cover 6 or the base 7 in the feed channel 13 is sequentially conveyed to the gripping position for gripping.

[0037] According to some embodiments of this application, the first motion module 2 includes a first column 21, a transverse cylinder 22, a first downward cylinder 23, and a first gripper 24. The transverse cylinder 22 is mounted on the first column 21. The transverse cylinder 22 is slidably engaged with the first downward cylinder 23. The first downward cylinder 23 is connected to the first gripper 24, which is used to grip the top cover 6.

[0038] Specifically, the first motion module 2 is located on one side of the material channel for conveying the cover, and the first pressing cylinder 23 is located directly above the material channel. The first pressing cylinder 23 is driven to move in the front-back direction by the transverse cylinder 22, and the first pressing cylinder 23 drives the first gripper 24 to move up and down, so as to transfer the cover at the gripping position on the material channel to the loading mechanism.

[0039] According to some embodiments of this application, the second motion module 3 includes a second column 31, a vertical module 32, a horizontal module 33, a rotating module 34, and a second pneumatic gripper 35. The vertical module 32 is mounted on the second column 31, and the vertical module 32 is connected to the horizontal module 33. The horizontal module 33 is slidably engaged with the rotating module 34. The lower end of the rotating module 34 is provided with a second gripper 35, which is used to grip the base 7.

[0040] Specifically, the second column 31 is located on one side of the material channel of the conveying base. The second column 31 is installed on the longitudinal module 30 so that the second column 31 moves in the left and right direction. The vertical module 32 is installed on the side wall of the second column 31. The horizontal module 33 is installed on the vertical module 32 so that the horizontal module 33 moves in the up and down direction. The rotating module 34 is installed on the horizontal module 33 so that the rotating module 34 moves in the front and back direction. The rotating module 34 moves the second gripper in a rotating motion, thereby realizing the position movement of the second gripper 35, and then transferring the base at the gripping position on the material channel to the loading mechanism.

[0041] According to some embodiments of this application, an elastic component is provided between the rotating module 34 and the second pneumatic gripper 35. The elastic component includes a fixed plate 351, a guide plate 362, a guide shaft 363, and an elastic element 364. One end of the guide shaft 363 is mounted on the fixed plate 361, and the other end passes through the guide plate 362. The elastic element 364 is disposed between the fixed plate 361 and the guide plate 362 and is sleeved on the guide shaft 363. The lower end of the guide plate 362 is connected to the second gripper 35, and the elastic force of the elastic element 364 is used to press the base and the top cover together.

[0042] Specifically, the rotating module 34 includes a servo motor 341 and a rotating shaft 342. The servo motor 341 is connected to the rotating shaft 342, and the rotating shaft 342 is connected to the fixed plate 351. The servo motor 341 drives the rotating shaft 342 to rotate, so that the elastic component rotates synchronously, which in turn links the second gripper 35 to rotate synchronously. After the second gripper 35 grips the base, it rotates to adjust the angle position of the base blades.

[0043] According to some embodiments of this application, the detection mechanism includes a first detection unit 41 and a second detection unit 42. The first detection unit 41 is used to detect the angular position of the upper cover blade, and the second detection unit 42 is used to detect the angular position of the base blade. The first detection unit 41 is mounted on the loading mechanism and is used to detect the angle of the upper cover blade 61. The second detection unit 42 is mounted on one side of the second motion module 3. After the second gripper 35 grasps the base, the angle of the base blade 71 is detected by the second detection unit 42, so that the angle between the base blade and the upper cover blade is maintained within the range of 1 to 10 degrees, so that the base blade can be inserted into the gap of the upper cover blade, and then the two are screwed together and assembled by rotating the base.

[0044] According to some embodiments of this application, the loading mechanism 5 includes a transfer module 51, a moving plate 52, a rotating assembly 53, and a clamping assembly. The moving plate 52 is slidably fitted to the transfer module 51. The rotating assembly 53 is mounted on the moving plate 52. The rotating assembly 53 is connected to the clamping assembly, which is used to clamp the base.

[0045] Furthermore, the rotating assembly 53 includes a rotating cylinder 531, a transmission belt 532, a rotating shaft 533, and a rotating plate 534. The rotating cylinder 531 is connected to the transmission belt 532, the transmission belt 532 is connected to the rotating shaft 533, the rotating plate 534 is rotatably connected to the rotating shaft 533, and a clamping assembly is installed on the rotating plate 534.

[0046] Furthermore, the clamping assembly includes a clamping cylinder 541 and two clamping blocks 542. One clamping block 542 is fixed on the rotating plate 534, and the other clamping block 542 is connected to the clamping cylinder 541. The clamping cylinder 541 drives the clamping block 542 to clamp and position the upper cover 6. The rotating cylinder 531 rotates in conjunction with the rotating shaft 533 via the transmission belt 532. The rotating shaft 533 rotates synchronously with the rotating plate 534, thereby achieving angle adjustment of the upper cover.

[0047] When the angle of the upper cover blade 61 deviates too much from the angle of the base blade 71 and cannot be engaged together, the angle of the upper cover blade 61 can be finely adjusted by rotating the rotating component 53, thereby ensuring that the base blade 71 and the upper cover blade 61 can be engaged together smoothly.

[0048] According to some embodiments of this application, an impeller assembly method is also provided, using the equipment described above, comprising the following steps:

[0049] S1. A conveying mechanism is used to transport the top cover and the base, so that the top cover and the base move to the gripping position respectively. Specifically, the vibration of two vibrating discs transports the top cover and the base sequentially to the gripping position along their respective feed channels.

[0050] S2. The detection mechanism is used to detect the upper cover blade and the base blade to ensure that the angles of the upper cover blade and the base blade are aligned and engaged. Specifically, the first detection unit and the second detection unit respectively detect the angles of the upper cover blade and the base blade to keep the blade angles within the range of 1 to 10 degrees, thereby enabling the base and the upper cover to be smoothly engaged together.

[0051] S3. The first motion module grips the top cover and transfers it to the loading mechanism, while the second motion module grips the base and transfers it to the loading mechanism. Rotation clamps the base blades and top cover blades together to form an impeller for welding. Specifically, the first motion module transfers the top cover to the loading mechanism, which then moves the top cover closer to the second motion module. The second motion module transfers the base to the loading mechanism, causing the base and top cover to engage. The second motion module then rotates the base, locking the base and top cover together and assembling them into an impeller for subsequent welding processes.

[0052] According to some embodiments of this application, by automatically assembling the top cover and the base into an impeller, it is possible to ensure that the top cover and the base are firmly assembled. The blades of the top cover and the blades of the base are arranged in an alternating manner to ensure the stability of subsequent welding. No manual operation is required, which helps to save labor costs, realize automated production, and improve work efficiency.

[0053] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0054] The above description is only a detailed explanation of the preferred embodiments and principles of this application. For those skilled in the art, there may be changes in the specific implementation based on the ideas provided by this invention, and these changes should also be considered within the scope of protection of this application.
