Description

Technical Field

[0001] The utility model relates to the technical field of rotor assembly, in particular to a conveying device for rotor assembly. Background Art

[0002] With the promotion of new energy and high-efficiency energy-saving technologies, outer rotor motors have received more extensive attention and applications due to their many advantages such as compact structure, excellent heat dissipation function, large torque, and low noise.

[0003] Different from traditional inner rotor motors, the rotor of an outer rotor motor is wrapped outside the stator, which requires higher overall assembly accuracy between the rotor and the stator. Moreover, since the mechanical structure of an outer rotor motor is often more complex than that of an inner rotor motor with the same power, the assembly process of traditional inner rotor motors has long relied on a mature and stable production line and technical system, and its structure is relatively simple. However, the rotor volume of an outer rotor motor increases and is directly exposed outside the motor housing, which requires more refined support structures and high-precision positioning devices during the assembly process to achieve precise alignment of the rotor and stator magnetic poles and avoid magnetic circuit interference and energy efficiency loss. However, currently, the assembly production lines optimized for inner rotor motors are often difficult to be directly migrated and applied to outer rotor motors, especially in terms of ensuring high-precision assembly and improving the overall system stability. Summary of the Utility Model

[0004] The utility model aims to provide a conveying device for rotor assembly to achieve high-precision assembly of an outer rotor motor and ensure the assembly quality.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A conveying device for rotor assembly includes a support frame, a conveying mechanism arranged on the support frame, and transfer mechanisms arranged at the left and right ends of the support frame. The conveying mechanism includes two layers of conveying sprockets distributed from top to bottom and a conveying tooling that is rotatably connected to the conveying sprockets. The upper and lower layers of conveying sprockets are connected through the transfer mechanisms; a plurality of installation stations for different processes are arranged on the support frame along the upper-layer conveying sprockets, and a number of stop components are arranged on the support frame along the conveying sprockets. The stop components are used to fix the conveying tooling at the positions where the installation stations are located. The stop components include a first sensor and a stop cylinder, and the first sensor is signal-connected to the stop cylinder.

[0006] The principle and advantages of this solution are:

[0007] 1. In actual application, the conveying tooling in this solution closely cooperates with the transfer mechanism through upper and lower layers of conveying sprockets to ensure the stability and position accuracy of the rotor during transportation. Among them, the rolling connection design of the conveying tooling reduces vibration and displacement errors during the assembly process, helps to achieve precise alignment at the key stage of assembly, and the stop component realizes intelligent control of the conveying tooling. The first sensor can monitor the position status of the conveying tooling in real time and trigger the stop cylinder based on this signal to ensure that each tooling accurately stops at the installation station, thereby reducing manual intervention, improving the automation level of assembly, ensuring the consistency and stability of high-precision assembly, significantly reducing magnetic circuit interference, and enhancing the efficiency of the outer rotor motor.

[0008] 2. Multiple installation stations provided on the support frame can correspond to different assembly processes, which means that the rotor can complete the entire process from cleaning, inspection to assembly on a continuous assembly line without frequent handling, reducing the risk of rotor damage and improving assembly efficiency. In addition, the multi-station design is convenient for implementing synchronous or serial fine operations and is suitable for the gradual construction of the complex structure of the outer rotor motor.

[0009] 3. In this solution, the transfer mechanism realizes a smooth transition between conveying sprockets at different heights or in different areas, enhancing the adaptability to the complex structure of the outer rotor motor. Moreover, the layout on the support frame can be flexibly adjusted according to the motor model, being suitable for both mass production of standard models and flexibly responding to customized or small-batch assembly requirements, improving the comprehensive efficiency of the production line.

[0010] Furthermore, a clamping component is provided at each installation station. The clamping components are symmetrically arranged on both sides of the support frame. The clamping component includes a clamping cylinder and a clamping block fixed on the output shaft of the clamping cylinder.

[0011] The position of the rotor housing on the conveying tooling is further adjusted and determined through the clamping component to ensure precise alignment between the rotor housing and the installation equipment at each installation station, achieving high-precision assembly and ensuring production quality.

[0012] Furthermore, a jacking component is provided at each installation station. The jacking component is fixed on the support frame and is arranged at the bottom of the conveying sprocket located in the upper layer.

[0013] The conveying tooling and the rotor housing thereon are jacked up by the jacking component to between the clamping components on both sides, separating the conveying tooling from the conveying sprocket, facilitating the effective clamping of the rotor housing by the clamping component, realizing secondary positioning, and avoiding the rotor housing from shaking and shifting due to the relative movement between the conveying tooling and the conveying sprocket during the magnetic sheet assembly, resulting in assembly errors and affecting assembly efficiency and quality.

[0014] Further, the transfer mechanism is a tray lifting mechanism, which includes a fixed frame, a supporting component slidably connected to the fixed frame, and a driving structure for driving the supporting component to lift. The supporting component includes a supporting bracket and a plurality of supporting rollers. Both ends of the supporting rollers are fixed on the supporting bracket, and the supporting rollers are electric rollers.

[0015] The tray lifting mechanism designed with a fixed frame and a slidably connected supporting component can more stably carry the rotor housing. Especially for the outer rotor motor components with large volume and heavy weight, the use of a plurality of supporting rollers disperses the load, reduces the deformation problem that may be caused by excessive single-point stress, and improves the smoothness and safety of the entire transfer process. Secondly, the plurality of supporting rollers are electric rollers, and the rotation of the electric rollers drives the conveying tooling to roll on them so that the conveying tooling is completely located on the supporting component or the conveying tooling is pushed onto the conveying sprocket, reducing manual intervention and realizing automatic transfer.

[0016] Further, a second sensor is provided on the supporting bracket, and the second sensor is signal-connected to the driving structure. By controlling the start and stop of the driving structure through the second sensor, it is ensured that each conveying tooling realizes transfer accurately, reducing manual intervention, improving the automation level of assembly, and ensuring production continuity.

[0017] Further, the conveying tooling is a rectangular tray. Both sides of the top of the support frame are in an L-shaped structure facing each other. Rollers are installed on both sides of the tray close to the support frame, and the rotation axes of the rollers are vertically arranged.

[0018] The rollers change the friction between both sides of the conveying tooling and the support frame from sliding friction to rolling friction, reducing the friction vibration and friction loss during the conveying process of the conveying tooling, and ensuring the stable conveying of the rotor housing.

[0019] Further, the opposite ends of the two clamping blocks are in a V shape.

[0020] The V-shaped end of the clamping block can naturally guide the centering of the rotor housing, which helps the rotor housing to be positioned quickly and accurately. At the same time, the V-shaped structure can be applied to the clamping of rotor housings of different specifications and sizes, without the need to frequently replace the clamping blocks, improving production efficiency.

[0029] The embodiment is basically as shown in the attached Figures 1-6 shown: A transfer device for rotor assembly includes a support frame 1, a conveying mechanism 2 arranged on the support frame 1, and a transfer mechanism arranged at the left and right ends of the support frame 1. The conveying mechanism 2 includes two layers of conveying sprockets 21 distributed from top to bottom and a conveying tooling 22 rotatably connected to the conveying sprockets 21. The upper and lower layers of conveying sprockets 21 are connected by a transfer mechanism, and both the upper and lower layers of conveying sprockets 21 are driven by 1 motor to rotate; the conveying tooling 22 is a rectangular tray. The two sides of the top of the support frame 1 are in an L-shaped structure facing each other. Both sides of the tray close to the support frame 1 are provided with rollers 23. The rotation axes of the rollers 23 are arranged vertically. The conveying sprockets 21 and the rollers 23 on the sides of the conveying tooling 22 change the friction between both sides and the bottom of the conveying tooling 22 and the support frame 1 from sliding friction to rolling friction, reducing the frictional vibration and frictional loss during the conveying process of the conveying tooling 22 and ensuring the stable conveying of the rotor housing.

[0030] A plurality of installation stations 3 for different processes are provided on the support frame 1 along the upper-layer conveying sprocket 21, including an installation station 3 for installing the rotor housing and the partition frame, an installation station 3 for installing magnetic sheets in the rotor housing, an installation station 3 for installing the gland on the rotor housing, etc.; a number of stop components 4 are arranged on the support frame 1 along the conveying sprocket 21. The stop components 4 are used to fix the conveying tooling 22 at the position where the installation station 3 is located, such as Figure 2As shown, the stopping component 4 includes a first sensor 41 and a stopping cylinder 42. The first sensor 41 is signal-connected to the stopping cylinder 42. The stopping cylinder 42 is vertically arranged, and a stopping seat 43 is installed at the top of its output shaft. The sensing lens of the first sensor 41 faces vertically upward. The first sensor 41 can monitor the position state of the conveying tooling 22 in real time and trigger the stopping cylinder 42 according to this signal, ensuring that each tooling accurately stops at the installation station 3, reducing human intervention, improving the automation level of assembly, ensuring the consistency and stability of high-precision assembly, being able to significantly reduce magnetic circuit interference, and improving the efficiency of the outer rotor motor.

[0031] As Figures 4-6 As shown in combination, the transfer mechanism is a tray lifting mechanism 5. The tray lifting mechanism 5 includes a fixed frame 51, a supporting component slidably connected to the fixed frame 51, and a driving structure for driving the supporting component to lift. In this embodiment, the driving structure is a driving cylinder 54. The supporting component includes a supporting frame 52 and a plurality of supporting rollers 53. Both ends of the plurality of supporting rollers 53 are fixed to the supporting frame 52. The supporting frame 52 is connected to the output shaft of the driving cylinder 54 through a transmission member 55. The supporting rollers 53 are electric rollers, and the electric rollers rotate to drive the conveying tooling 22 to move so that the conveying tooling 22 is completely located on the supporting component or transfer the conveying tooling 22 to the conveying sprocket 21. A second sensor 58 is also provided on the supporting frame 52. The second sensor 58 is signal-connected to the driving structure. The second sensor 58 is installed on the side away from the support frame 1 and its sensing lens is horizontally arranged and faces the support frame 1. The start and stop of the driving structure are controlled by the second sensor 58 to ensure the accurate transfer of each conveying tooling 22, reducing human intervention, improving the automation level of assembly, and ensuring production continuity. Guide structures are also provided on both sides of the supporting frame 52. The guide structures include guide rods 56 and guide blocks 57 slidably connected to the guide rods 56. One side of the guide block 57 is fixedly connected to the supporting frame 52. The guide structures make the conveying tooling 22 more stable during lifting and transfer.

[0032] As Figure 3 As shown, a clamping component 6 is provided at each installation station 3. The clamping components 6 are symmetrically arranged on both sides of the support frame 1. The clamping component 6 includes a clamping cylinder 61 and a clamping block 62 fixed on the output shaft of the clamping cylinder 61. The opposite ends of the two clamping blocks 62 are V-shaped, and the V-shaped end design can naturally guide the centering of the rotor housing, helping the rotor housing to be quickly and accurately positioned.

[0033] As Figure 2As shown in the figure, a lifting assembly 7 is provided at each installation station 3. The lifting assembly 7 is fixed on the support frame 1 and is arranged at the bottom of the upper conveying sprocket 21. The lifting assembly 7 includes a lifting cylinder 71 and a transmission plate 72. The transmission plate 72 is fixed at the end of the output shaft of the lifting cylinder 71. The lifting assembly 7 jacks up the conveying tooling 22 and the rotor housing thereon to between the clamping assemblies 6 on both sides, so that the conveying tooling 22 is separated from the conveying sprocket 21, facilitating the effective clamping of the rotor housing by the clamping assemblies 6, realizing secondary positioning, and avoiding the shaking and offset of the rotor housing caused by the relative movement between the conveying tooling 22 and the conveying sprocket 21 during the magnetic sheet assembly, resulting in assembly errors and affecting the assembly efficiency and quality.

[0034] Specific implementation process:

[0035] This implementation process is based on Figure 1 and among them Figure 1 the conveying direction of the upper conveying sprocket 21 is from left to right, and the conveying direction of the lower layer is from right to left. In the initial state, the supporting assembly of the left tray lifting mechanism 5 is flush with the lower conveying sprocket 21, and the supporting assembly of the right tray lifting mechanism 5 is flush with the upper conveying sprocket 21.

[0036] In specific applications, the upper and lower conveying sprockets 21 are both driven by motors to rotate and drive the conveying tooling 22 and the rotor housing thereon to move horizontally. When the first inductor 41 senses the conveying tooling 22, it transmits the sensing signal to the stop cylinder 42. The stop cylinder 42 pushes the stop seat 43 upward to stop the conveying tooling 22. Then the lifting cylinder 71 at the installation station 3 jacks up the conveying tooling 22, and the clamping cylinder 61 pushes the clamping block 62 to clamp the rotor housing. Then the assembly work at this installation station 3 is completed, and then each cylinder resets. The conveying tooling 22 continues to be conveyed forward until the next installation station 3; when the conveying tooling 22 is at the rightmost end of the upper conveying sprocket 21, the rotor assembly is completed, and the finished product is transferred and collected by the manipulator. At this time, the conveying tooling 22 continues to be transported to the supporting assembly by the conveying sprocket 21 to the right. When the second inductor 58 on the supporting bracket 52 senses the conveying tooling 22, it controls the driving cylinder 54 to start and descend to the height of the lower conveying sprocket 21, and is driven by the electric roller to be transferred to the conveying sprocket 21. Then the supporting assembly at the right end resets, and the conveying tooling 22 continues to be conveyed to the left to the supporting assembly at the left end. Similarly, it is transported upward to the height of the upper conveying sprocket 21 by the driving cylinder 54 and transferred to the conveying sprocket 21. Then the manipulator places the rotor housing to be assembled, and continues to repeat the above operation process to complete the assembly.

[0037] The above are only embodiments of the present utility model, and common general technical solutions and / or characteristics in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solutions of the present utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
