[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit it. It should be noted that this utility model is already in the actual research and development stage.

[0037] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0038] Traditional motor rotor sleeve-fitting devices rely on manual operation or simple machinery, resulting in low precision, poor efficiency, insufficient flexibility, and safety hazards. Manual operation is affected by experience and fatigue, leading to unstable product quality and a high defect rate. Low automation requires manual placement of workpieces, which is inefficient and prone to errors, failing to meet the demands of high-efficiency and precise production. Furthermore, these devices are often designed for specific models, lacking flexibility and requiring frequent adjustments when producing different specifications, resulting in low equipment utilization. Simultaneously, the lack of effective stabilization and limiting devices poses safety hazards such as workpiece slippage and clamping, affecting production safety and product quality.

[0039] Example 1:

[0040] like Figures 1 to 3 As shown, a sleeve-fitting device for a motor rotor is disclosed. The rotor consists of a rotating shaft and a magnet. The device also includes a frame 1, on which two vibrating discs 2 are mounted. One vibrating disc 2 contains the rotating shaft, and the other vibrating disc 2 contains the magnet. Each vibrating disc 2 is connected to a conveying mechanism. The frame 1 also includes a horizontal column 3 and two vertical columns 301. The vertical columns 301 are located at both ends of the horizontal column 3, with one end connected to the end of the horizontal column 3 and the other end connected to the frame 1. The horizontal column 3 is equipped with a clamping mechanism for picking up the workpiece from the conveying mechanism. The frame 1 also includes a sleeve-fitting mechanism and a transfer mechanism. The sleeve-fitting mechanism is used to insert the rotating shaft into the magnet, and the transfer mechanism is used to transport the sleeved rotor.

[0041] The frame 1 is the basic support structure of the entire device, on which two vibratory feeders 2 are installed, used for storing and automatically sorting the rotating shafts and magnets respectively. The vibratory feeders 2 use vibration to transport the workpieces in an orderly manner to the conveying mechanism, ensuring that the workpieces can continuously and accurately enter subsequent processes. The frame 1 also has a horizontal column 3 and two vertical columns 301. The horizontal column 3 is used to install a clamping mechanism, which can move along the length of the horizontal column 3 to grasp and place the workpieces. The two ends of the horizontal column 3 are connected to the frame 1 through the vertical columns 301, forming a stable support structure to ensure that the clamping mechanism remains stable during movement. The frame 1 also has a sleeve mechanism and a transfer mechanism. The sleeve mechanism is responsible for inserting the rotating shaft into the magnet to complete the sleeve action, while the transfer mechanism is responsible for transporting the sleeved rotor to the next station. This design, through a reasonable mechanical structure layout, achieves orderly supply, precise clamping, and efficient sleeve of workpieces, meeting the needs of automated production of motor rotors.

[0042] like Figure 4As shown, as an optimized solution of this embodiment, the conveying mechanism includes a conveying pipe 202 and a placement platform 203. One end of the conveying pipe 202 is connected to the interior of the vibrating plate 2, and the other end of the conveying pipe 202 is connected to the placement platform 203.

[0043] It should be noted that the design of the conveyor pipe 202 must ensure that its inner diameter matches the size of the workpiece to prevent the workpiece from jamming or shifting. The conveyor pipe 202 is typically made of wear-resistant material to withstand the friction and wear of the workpiece during the conveying process. The placement table 203 is used to temporarily store the workpiece conveyed from the conveyor pipe 202, and its surface should have an anti-slip design.

[0044] like Figure 1 and Figure 5 As shown, the clamping mechanism includes a first robotic arm 302 and a second robotic arm 303 that can move along the length of the horizontal column 3; the first robotic arm 302 is located on one side of the horizontal column 3, and the second robotic arm 303 is located on the horizontal column 3 and on the opposite side of the side where the first robotic arm 302 is located.

[0045] The first robotic arm 302 is located on one side of the horizontal column 3 and is used to grip and place the rotating shaft, while the second robotic arm 303 is located on the other side of the horizontal column 3 and is used to grip and place the magnet. The two robotic arms can operate simultaneously and independently without interfering with each other, thereby improving production efficiency. The movement paths of the robotic arms are designed along the length of the horizontal column 3, enabling them to cover all positions between the vibratory feeder 2 and the sleeve mechanism, ensuring accurate gripping and placement of workpieces in different locations. The gripping parts of the robotic arms are typically pneumatically or electrically driven, ensuring that the gripping force is moderate and adjustable to accommodate workpieces of different sizes and weights.

[0046] like Figure 1 and Figure 6As shown, the sleeve-feeding mechanism includes a first guide rail 4 mounted on the frame 1, a slider 401 slidably connected to the first guide rail 4, a push rod 402 connected to the slider 401, a guide block 403 connected to the first guide rail 4, a first groove 404 provided on the guide block 403, one end of the push rod 402 connected to the slider 401, and the other end of the push rod 402 extending into the first groove 404; the sleeve-feeding mechanism also includes a slide block 5 mounted on the frame 1, a first cylinder 501 mounted on the slide block 5, and a cylinder 501... One end of the first piston rod 502 is located inside the first cylinder 501, and the other end of the first piston rod 502 is provided with a guide plate 505. The guide plate 505 is provided with a second groove 504, and the first piston rod 502 can extend into the second groove 504. When the rotating shaft is placed into the first groove 404 by the first robotic arm 302 and the magnet is placed into the second groove 504 by the second robotic arm 303, the push rod 402 and the first piston rod 502 move towards each other, so that the rotating shaft is inserted into the magnet, completing the insertion.

[0047] After the rotating shaft and the magnet are placed in their respective grooves, the push rod 402 and the first piston rod 502 move towards each other simultaneously. The push rod 402 pushes the rotating shaft, and the first piston rod 502 pushes the magnet, so that the rotating shaft is precisely inserted into the magnet, completing the insertion action.

[0048] like Figure 1 and Figure 6 As shown, the transfer mechanism includes a conveyor belt 6 mounted on the slide block 5 and a drive mechanism for pushing the slide block 5. The length direction of the conveyor belt 6 is on the same straight line as the length direction of the first piston rod 502. A second guide rail 7 matching the bottom of the slide block 5 is also provided below the slide block 5. The slide block 5 can move back and forth on the second guide rail 7 in a direction perpendicular to the push rod 402. When putting on the sleeve, the slide block 5 moves the first piston rod 502 to a position where the length direction of the first piston rod 502 is on the same straight line as the length direction of the push rod 402. When transferring, the slide block 5 moves the conveyor belt 6 to a position where the length direction of the conveyor belt 6 is on the same straight line as the length direction of the push rod 402.

[0049] After the sleeve is inserted, the slide block 5 moves under the drive mechanism, moving the conveyor belt 6 to a position parallel to the push rod 402. Then, the push rod 402 continues to push forward, pushing the inserted rotor out of the first groove 404 and onto the conveyor belt 6, completing the rotor transfer. A second guide rail 7 is provided below the slide block 5, and the slide block 5 can move back and forth on the second guide rail 7 in a direction perpendicular to the push rod 402 to ensure that the conveyor belt 6 can be accurately moved to the designated position.

[0050] As an optimized solution of this embodiment, the driving mechanism includes a second cylinder 601 disposed on the frame 1, a second piston rod 602 disposed in the second cylinder 601, one end of the second piston rod 602 being located in the second cylinder 601, and the other end of the second piston rod 602 being connected to the slide block 5.

[0051] The second cylinder 601 controls the extension and retraction of the second piston rod 602, pushing the slide 5 to move along the second guide rail 7, thereby realizing the movement and positioning of the conveyor belt 6. The second cylinder 601 can be driven by pneumatic or electric power to ensure that the slide 5 can move smoothly and accurately to the designated position.

[0052] As an optimized solution in this embodiment, the frame 1 is further provided with a stabilizing block 8. The stabilizing block 8 has an opening, the diameter of which matches that of the push rod 402, and the opening and the push rod 402 are concentric. The function of the stabilizing block 8 is to provide stable support and guidance, ensuring that the push rod 402 maintains precise linear motion during movement and preventing the push rod 402 from deflecting or shifting under the action of thrust. The design of the opening requires precise machining to ensure that the push rod 402 can slide freely within the opening while maintaining good coaxiality.

[0053] Example 2:

[0054] like Figure 6 As shown, as a supplement to Embodiment 1, there are two second guide rails 7. The two second guide rails 7 are located on either side of the slide 5. The design of two second guide rails 7 provides more stable guidance and support, ensuring that the slide 5 remains stable during movement and preventing tilting or offset during movement. The parallelism of the two second guide rails 7 needs to be precisely controlled to ensure that the slide 5 can move accurately in a direction perpendicular to the push rod 402.

[0055] like Figure 4 As shown, each of the placement stages 203 is also provided with two limiting blocks 204. The obstruction space formed between the two limiting blocks 204 can prevent the workpiece from slipping after it comes out of the output tube. The limiting blocks 204 are usually made of wear-resistant materials to withstand the friction and wear of the workpiece during placement and clamping.

[0056] Furthermore, the displacement length of the second piston rod 602 within the second cylinder 601 is L1, and the length of each of the second guide rails 7 is L2, satisfying L1≥L2. This ensures that the stroke of the second piston rod 602 will not exceed the length of the second guide rail 7, thereby avoiding excessive displacement or jamming when the second piston rod 602 pushes the slide 5 to move. Simultaneously, the L1≤L2 design provides greater adjustment space for the precise positioning of the slide 5, allowing the conveyor belt to move more accurately to the designated position, ensuring that the rotor after being fitted can be smoothly transferred onto the conveyor belt, further improving the automation level and production efficiency of the device.

Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this disclosure.
