[0002] Currently, although the assembly of rotors in motors has been automated, the various automated equipment varies in quality, structure, and yield rate. During rotor assembly, especially the assembly of the rotor core and magnets, precise allocation and real-time monitoring are required due to the different magnetic poles of adjacent magnets to ensure yield. However, the current automated assembly equipment falls far short of meeting these requirements in terms of intelligence. Summary of the Invention

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0042] Reference Figures 1 to 3 This application provides a rotor assembly equipment, including a workbench 10, an insertion station 20 on the workbench 10 for inserting magnetic tiles 2 into a rotor core 1, a magnetic tile insertion device 30 above the insertion station 20, a detection station 40 for detecting the inserted magnetic tiles 2, a pressing station 50 for pressing the rotor shaft into the rotor, a shaft conveying device 60 for conveying the rotor shaft 3 to the pressing station 50, a first picking device 70 for conveying the rotor core 1 between the insertion station 20, the detection station 40, and the pressing station 50, and a control system for coordinating the operation of the above devices.

[0043] The rotor assembly equipment provided in this application involves transporting the rotor core 1 to the insertion station 20, where the magnetic tile insertion device 30 inserts the magnetic tile 2 into the rotor core 1. Then, the first picking device 70 picks it up and transports it to the inspection station 40 for inspection. After passing the inspection, the magnetic tile 2 is transported to the pressing shaft station 50 by the first picking device 70 for installation of the rotor shaft 3. The rotor shaft 3 is transported by the shaft conveying device 60. In the above assembly process, the magnetic tile insertion device 30 realizes the automatic insertion of the magnetic tile 2, and the inspection station 40 ensures the accuracy of the installation of the magnetic tile 2. The entire equipment has high assembly efficiency and significantly improved intelligence.

[0044] Depend on Figure 1 It can also be seen that in this embodiment, the rotor assembly equipment has a housing 101 to protect the aforementioned devices, and it is used in conjunction with a conveying platform (not shown in the figure). The conveying platform is located on one side of the rotor assembly equipment, and the rotor core 1 to be assembled is conveyed to the rotor assembly equipment through the conveying platform. A third picking device 102 is also provided on the workbench 10, and an alignment station 80 is provided near the edge of the workbench 10. The third picking device 102 picks up the rotor core 1 from the conveying platform and places it on the alignment station 80. Since the rotor core 1 is randomly placed on the conveying platform, it remains randomly placed after being picked up by the third picking device 102. Combined with... Figure 4 When the rotor core 1 is inserted at the insertion station 20, the magnetic tile groove 11 on the rotor core 1, which is used to accommodate the magnetic tile 2, must be aligned with the magnetic tile 2. Since the position of the magnetic tile 2 is fixed, the rotor core 1 needs to be aligned at the alignment station 80 to facilitate the subsequent insertion of the magnetic tile 2. Specifically, a turntable 81 is provided at the alignment station 80, and a sensing device (not shown in the figure) is also provided next to the alignment station 80. For example, the sensing device can be a laser sensor. When the laser emitted by the laser sensor passes through the magnetic tile groove 11 of the rotor core 1, it indicates that the rotor core 1 is in the correct position. Otherwise, the rotor core 1 needs to be rotated by the turntable 81 until the magnetic tile groove 11 is aligned with the laser sensor.

[0045] Depend on Figure 2 As can be seen, the insertion station 20, the inspection station 40, and the pressing station 50 are equally spaced. The insertion station 20 includes a first horizontal moving device 21, a first rotating device 22 mounted on the first horizontal moving device 21 for fixing the rotor core 1 and driving the rotor core 1, and a lifting mechanism 23 located at the bottom of the first rotating device 22. When the aligned rotor core 1 is transferred to the insertion station 20 by the first picking device 70, the rotor core 1 is placed on the first rotating device 22 and located at one end of the first horizontal moving device 21. By moving the first horizontal moving device 21, it is moved closer to the magnetic tile insertion device 30. When it is in place, the lifting mechanism 23 lifts the first rotating device 22 and the rotor core 1 to facilitate the subsequent insertion of the magnetic tile 2.

[0046] Depend on Figure 5 , Figure 6 As can be seen, the magnetic tile insertion device 30 includes a magnetic tile slide platform 31 located at the top of one side of the first horizontal moving device 21, an adsorption device 32 located opposite to the magnetic tile slide platform 31 for adsorbing the magnetic tile 2 on the magnetic tile slide platform 31 outward, and a first pushing device 33 located above the magnetic tile slide platform 31 and movable downward to push the magnetic tile 2 into the rotor core 1.

[0047] Specifically, the magnetic tile slide platform 31 is placed on the second horizontal moving device 34, and the magnetic tile slide platform 31 includes multiple slides 311 for placing magnetic tiles 2. Multiple magnetic tiles 2 are placed abutting against each slide 311. As shown in the figure, there are 12 slides 311. Each magnetic tile 2 in each slide 311 has the same polarity when manually placed. In this embodiment, a magnetic pole sensor (not shown in the figure) is provided in each slide 311. Simultaneously, a display screen (not shown in the figure) is also provided on the magnetic tile slide platform 31. The display screen is connected to the magnetic pole sensor in each slide 311. When the magnetic tile 2 in each slide 311 is correctly placed, a green light is displayed on the display screen; when incorrectly placed, a red light is displayed on the display screen, thus reminding the operator to make corrections. At the same time, a first proximity switch (not shown in the figure) is also provided in each slide 311, near the adsorption device 32, to detect whether the magnetic tile 2 in the entire slide 311 has been pushed into place. Because when the magnetic tile 2 is placed into the slide 311, it needs to be pushed forward so that the frontmost magnetic tile 2 is close to the adsorption device 32 and can be adsorbed by the adsorption device 32 to the designated position, and then pushed down by the first pushing device 33 to be inserted into the rotor core 1, a first proximity switch needs to be set in the slide 311 to detect whether the magnetic tile 2 has been pushed into place.

[0048] In this embodiment, the adsorption device 32 is fixed in position, corresponding to two slides 311 each time. Correspondingly, the first pushing device 33 pushes two magnetic tiles 2 into the rotor core 1 each time. For each slide 311, the first magnetic tile 2 is adsorbed by the adsorption device 32 and pushed into the rotor core 1 by the first pushing device 33. After insertion, the first pushing device 33 returns to its original position, and the next magnetic tile 2 is again adsorbed by the adsorption device 32 and inserted by the first pushing device 33. Thus, when all the magnetic tiles 2 on both slides 311 are inserted, the second horizontal moving device 34 moves the magnetic tile slide platform 31, causing the next two slides 311 to align with the adsorption device 32 again, repeating the aforementioned adsorption and insertion actions until all the magnetic tiles 2 on the two slides 311 are inserted into the rotor core 1. For a single rotor core 1, the process continues... Figure 4As can be seen, the magnetic tile grooves 11 of the rotor core 1 are equally angularly distributed. As shown in the figure, there are eight magnetic tile grooves 11, which are arranged in pairs opposite to each other, and the overall shape is a "rice" shape. When the rotor core 1 is in its initial position on the first rotating device 22, the first group of magnetic tile grooves 11 located on the same straight line are located below the first pushing device 33. In this way, after the two magnetic tiles 2 in the two slideways 311 are pushed downward, they just insert into two opposite magnetic tile grooves 11. After completing this insertion action, the first rotating device 22 drives the rotor core 1 to rotate 90 degrees, so that the second group of two opposite magnetic tile grooves 11 are aligned with the first pushing device 33 to complete the insertion action; again, the first rotating device 22 drives the rotor core 1 to rotate 45 degrees, so that the third group of two opposite magnetic tile grooves 11 are aligned with the first pushing device 33 to complete the insertion action; finally, the first rotating device 22 drives the rotor core 1 to rotate 90 degrees, so that the fourth group of two opposite magnetic tile grooves 11 are aligned with the first pushing device 33 to complete the insertion action. In this way, through four insertions, two magnetic tiles 2 are inserted each time, and the insertion action of the magnetic tiles 2 into the eight magnetic tile grooves 11 is completed.

[0049] Further, the first pushing device 33 includes a longitudinal slide rail 331 provided on one side of the magnetic tile slideway platform 31, a pushing block 332 provided on the longitudinal slide rail 331, and a vertical air cylinder 333 that drives the pushing block 332 to move up and down. In this embodiment, the longitudinal slide rail 331 runs through from front to back, the front side is directly opposite to the adsorption device 32, and the back side is connected to the two slideways 311. At the position in the longitudinal slide rail 331 that is directly opposite to the adsorption device 32 and the two slideways 311, an adsorption activity area for the adsorption device 32 to adsorb the magnetic tile 2 is formed.

[0050] Specifically, the adsorption device 32 includes a horizontal air cylinder 321 and a buffer pad 322 provided at the output end of the horizontal air cylinder 321. The buffer pad 322 is directly opposite to the longitudinal slide rail 331 and the slideway 311. Correspondingly, the horizontal air cylinder 321 has two output ends, which respectively correspond to the two slideways 311. The output end of the horizontal air cylinder 321 is a piston, and the piston is made of metal and has an adsorption force relative to the magnetic tile 2. When the piston of the horizontal air cylinder 321 moves forward, that is, moves towards the slideway 311, it adsorbs the magnetic tile 2 in the slideway 311 backward and adsorbs the magnetic tile 2 into the longitudinal slide rail 331. At this time, the pushing block 332 of the first pushing device 33 is directly opposite to the magnetic tile 2. When the pushing block 332 moves downward under the drive of the vertical air cylinder 333, it inserts the magnetic tile 2 into the rotor core 1. Since the magnetic tile 2 is relatively brittle, there is a risk of impact damage when adsorbing to the output end of the horizontal air cylinder 321. In this embodiment, a buffer pad 322 is provided at the output end of the horizontal air cylinder 321. The buffer pad 322 is made of a flexible material, which protects the magnetic tile 2 and does not affect the magnetic adsorption effect between the output end of the horizontal air cylinder 321 and the magnetic tile 2.

[0051] In this embodiment, after the rotor core 1 on the first rotating device 22 completes the insertion of eight magnetic tiles 2, the first horizontal moving device 21 drives the first rotating device 22 and the rotor core 1 on it to move to the other side, that is, to move to a position closer to the first picking device 70, so that the first picking device 70 can transfer it from the insertion station 20 to the detection station 40.

[0052] Specifically, refer to Figure 7 The inspection station 40 includes a first clamping device 41 for placing the rotor core 1, a second rotating device 42 for rotating the first clamping device 41, and an inspection assembly 43 located on one side of the first clamping device 41 for inspecting the magnetic tile 2. The inspection assembly 43 includes two magnetic pole sensors 431, which are used to detect the areas on both sides of the magnetic tile 2. The two magnetic pole sensors 431 detect the same pole. When the magnetic tile 2 is inserted correctly, the same magnetic pole sensor 431 lights up simultaneously; otherwise, it indicates that the magnetic tile 2 is inserted incorrectly.

[0053] In this embodiment, the pressing station 50 includes a second clamping device 51 for placing the rotor core 1, and a pressing device (not shown in the figure) located above the second clamping device 51 for applying pressure to the rotor shaft 3. After the rotor shaft 3, conveyed by the shaft conveying device 60, is placed inside the rotor core 1, the pressing device moves downward to press the rotor shaft 3 into place.

[0054] Depend on Figure 2 , Figure 8 As can be seen, the alignment station 80, insertion station 20, inspection station 40, and pressing station 50 are arranged at equal intervals. In this embodiment, the first picking device 70 includes a fourth horizontal moving device 71 and three second robotic arms 72 equally spaced on the fourth horizontal moving device 71. When the fourth horizontal moving device 71 moves, it drives the three second robotic arms 72 to sequentially transfer the rotor core 1 at the alignment station 80, insertion station 20, inspection station 40, and pressing station 50. In this way, multiple stations can be transferred simultaneously through a single horizontal moving device, greatly improving efficiency and facilitating the rational layout of the various devices on the workbench 10.

[0055] Reference Figure 2 , Figure 9 and Figure 10The shaft conveying device 60 includes a hopper 61, a support plate 62 located at the bottom of the hopper 61 and communicating with the hopper 61 for loading the rotor shaft 3, a third horizontal moving device 63 for driving the support plate 62 to move horizontally, a detection table 64 located on one side of the third horizontal moving device 63, a second pushing device 65 located on one side of the hopper 61 for pushing the rotor shaft 3 into the detection table 64, and a second picking device 66 for picking up the rotor shaft 3 from the detection table 64. Specifically, the hopper 61 is enclosed by three vertical plates 611 and an inclined plate 612, and the bottom of the hopper 61 has an opening, with the support plate 62 located at the opening. During discharge, the rotor shaft 3 rolls from the inclined plate 612 onto the support plate 62 at the bottom of the hopper 61. The support plate 62 is provided with multiple receiving grooves 621 for accommodating the rotor shaft 3. The receiving groove 621 is parallel to the inclined plate 612, and the cross-section of the receiving groove 621 is triangular. In this way, the receiving groove 621 plays a good role in limiting the rotor shaft 3 and preventing the rotor shaft 3 from rolling in the receiving groove 621 when the support plate 62 moves with the third horizontal moving device 63.

[0056] Since the rotor shafts 3 of different motors have different lengths, and to prevent the rotor shaft 3 from tilting when it rolls from the inclined plate 612 onto the support plate 62, the vertical plates 611 on both sides of the inclined plate 612 limit the two ends of the rotor shaft 3, that is, the distance between the two vertical plates 611 matches the length of the rotor shaft 3. In order to enable the hopper 61 to accommodate the rotor shaft 3, in this embodiment, a limiting device 67 is provided in the hopper 61 along a direction perpendicular to the rotor shaft 3, which is used to move according to the length of the rotor shaft 3.

[0057] Specifically, the limiting device 67 includes a movable rod 671 horizontally passing through one of the vertical plates 611, a limiting plate 672 connected to the inside of the movable rod 671 and disposed within the hopper 61, and a fixing assembly 673 disposed outside the vertical plate 611 for fixing the movable rod 671. The limiting plate 672 is parallel to the vertical plate 611, and the limiting plate 672 and the other vertical plate 611 act as limiting components at both ends of the rotor shaft 3. When the rotor shaft 3 is long, the fixing assembly 673 is unlocked, and the movable rod 671 is pulled outward, increasing the distance between the limiting plate 672 and the other vertical plate 611 to match the length of the rotor shaft 3. Similarly, when the rotor shaft 3 is short, the fixing assembly 673 is unlocked, and the movable rod 671 is pushed inward, decreasing the distance between the limiting plate 672 and the other vertical plate 611 to match the length of the rotor shaft 3. In order to better pull the limiting plate 672 outward or push the limiting plate 672 inward, in this embodiment, there are two movable rods 671, and correspondingly, there are also two fixed components 673. In order to ensure the consistency of movement of the movable rods 671, the two movable rods 671 are connected together by a connecting plate 674.

[0058] In this embodiment, a proximity switch (not shown in the figure) is also provided in the receiving groove 621 on the support plate 62 to sense whether the rotor shaft 3 has fallen into the receiving groove 621. When the rotor shaft 3 has not fallen into the receiving groove 621, the proximity switch sounds an alarm to remind the operator to add material to the hopper 61. After the receiving groove 621 on the support plate 62 receives the rotor shaft 3, the third horizontal moving device 63 drives the support plate 62 and the rotor shaft 3 on it to move horizontally, so that the rotor shaft 3 moves to a position facing the detection table 64. Then, the second pushing device 65 pushes the rotor shaft 3 horizontally from one end onto the detection table 64. Specifically, the second pushing device 65 includes a servo motor 651 fixed to the outside of the hopper 61 and a push block 652 driven by the servo motor 651. The push block 652 is located on one side of the support plate 62 and is directly opposite the receiving groove 621. When the servo motor 651 drives the push block 652 to move, the push block 652 pushes the rotor shaft 3 into the detection table 64. The detection table 64 has a notch 641 that matches the rotor shaft 3.

[0059] Since the rotor shaft 3 is not a shaft of equal diameter, but has a large end and a small end, in this embodiment, a first sensing element (not shown in the figure) for detecting the placement direction of the rotor shaft 3 is also provided on the detection table 64 to ensure that the rotor shaft 3 is placed in a preset direction, which facilitates the subsequent pressing process of the rotor shaft 3. Specifically, the first sensing element is a proximity switch, which is set at the large end or the small end. When the corresponding large end or the small end of the rotor shaft 3 is in place, the proximity switch lights up; otherwise, it does not light up, thereby detecting the placement direction of the rotor shaft 3.

[0060] In this embodiment, although a limiting device 67 is provided in the hopper 61 to accommodate rotor shafts 3 of different lengths, the limiting device 67 can only screen out rotor shafts 3 that are longer than the qualified rotor shaft 3. However, when the fed rotor shaft 3 is shorter than the predetermined rotor shaft 3, the limiting device 67 cannot screen it out. For example, when installing a 20cm rotor shaft 3, if a 25cm rotor shaft 3 is mixed in, because the distance between the limiting plate 672 and the vertical plate 611 is 20cm, the 25cm rotor shaft 3 cannot enter the hopper 61, but the 15cm rotor shaft 3 can be mixed in and enter the receiving groove 621 of the support plate 62 through the hopper 61. Therefore, it is necessary to further detect the length of the rotor shaft 3 to screen out unqualified rotor shafts 3.

[0061] Specifically, in this embodiment, the detection table 64 is provided with a limiting member 642 for limiting the rotor shaft 3. Specifically, the limiting member 642 is located at the end of the notch 641 on the detection table 64. When the pusher block 652 pushes the rotor shaft 3 against the limiting member 642, the rotor shaft 3 cannot continue to move, and the servo motor 651 stops rotating. The servo motor 651 is connected to a stroke control circuit for detecting the length of the rotor shaft 3. Specifically, when the rotor shaft 3 reaches the limiting member 642 and cannot move, the pulse value of the servo motor 651 can be obtained. Then, based on the determined stroke distance of each pulse, the stroke of the pusher block 652 can be obtained. This stroke is then compared with the stroke of a qualified rotor shaft 3. When the two are equal, the rotor shaft 3 is qualified. When the stroke is greater than the stroke of a qualified rotor shaft 3, it indicates that the rotor shaft 3 is too short and is an unqualified rotor shaft 3.

[0062] In this embodiment, a first recycling device 90 is also provided on the workbench 10 and on one side of the shaft conveying device 60. The first recycling device 90 is used to recycle the aforementioned unqualified rotor shaft 3. The unqualified rotor shaft 3 is picked up by the second picking device 66 and placed into the first recycling device 90.

[0063] In this embodiment, the second picking device 66 includes a vertical moving device 661 and a flipping robot 662 mounted on the vertical moving device 661. Since the rotor shaft 3 is placed horizontally on the inspection table 64, the flipping robot 662 picks it up and flips it 90 degrees, so that the rotor shaft 3 changes from horizontal to vertical, which facilitates the subsequent rotor shaft 3 insertion process.

[0064] Furthermore, by Figure 3 As can be seen, a transfer platform 663 is also provided on the worktable 10. After the flipping robot 662 flips the rotor shaft 3 to a vertical position, it is placed on the transfer platform 663. The transfer platform 663 then horizontally transfers the rotor shaft 3 to the pressing station 50. Specifically, the transfer platform 663 has a fifth horizontal moving device 6631 and a first robot 6632 located on the fifth horizontal moving device 6631. The flipping robot 662 inserts the vertical rotor shaft 3 into the first robot 6632, and then the fifth horizontal moving device 6631 moves it horizontally to the pressing station 50.

[0065] Reference Figure 3 In this embodiment, a fourth picking device 103 is also provided on the workbench 10 and next to the pressing station 50. After the rotor core 1 is pressed by the pressing station 50, it needs to be further inspected. For rotor core 1 that is not qualified by pressing, it is picked up by the fourth picking device 103 and placed in the unqualified area. For qualified rotor core 1, it is picked up in the qualified area.

[0066] In this embodiment, the working principle of the rotor assembly equipment is as follows: the rotor core 1 is transported to the side of the rotor assembly equipment via the conveying platform, specifically located on one side of the alignment station 80. The third picking device 102 transfers the rotor core 1 from the conveying platform to the alignment station 80, and the alignment station 80 rotates the rotor core 1 to a preset position. The second robotic arm 72 on the first picking device 70 transfers the rotor core 1 from the alignment station 80 to the insertion station 20. The first horizontal moving device 21 moves it closer to the magnetic tile insertion device 30. When it is in place, the lifting mechanism 23 lifts the first rotating device 22 and the rotor core 1. At this time, the magnetic tile insertion device 30... Two magnetic tiles 2 are attracted by the adsorption device 32 and pushed into the first pushing device 33, which then pushes them into the rotor core 1. After one insertion action is completed, the first rotating device 22 drives the rotor core 1 to rotate 90 degrees, so that the two opposing magnetic tile slots 11 of the second set are aligned with the first pushing device 33 to complete the insertion of the two magnetic tiles 2. The above actions are repeated until all eight magnetic tile slots 11 are inserted into the magnetic tiles 2. Then, the first horizontal moving device 21 drives the rotor core 1 to move horizontally to the other side of the insertion station 20. The second second robotic arm 72 on the first picking device 70 picks it up and places it on the detection station 40. The detection component 43 on the detection station 40 detects whether the magnetic tile 2 is inserted into the rotor core 1. If any omissions or incorrect insertion direction are detected, the third robotic arm 72 picks it up and places it on the pressing station 50. At this time, the rotor shaft 3 on the hopper 61 of the shaft conveying device 60 falls onto the support plate 62. The third horizontal moving device 63 drives the support plate 62 and the rotor shaft 3 on it to move horizontally, so that the rotor shaft 3 is positioned facing the inspection table 64. Then, the second pushing device 65 pushes the rotor shaft 3 horizontally from one end onto the inspection table 64. During the pushing process, the servo motor 651 is connected to a stroke control circuit to detect the length of the rotor shaft 3. At the same time, the first sensor on the inspection table 64 detects whether the placement direction of the rotor shaft 3 is correct. When the rotor shaft 3 is defective, the flipping robot 662 of the second picking device 66 picks it up and puts it into the first recycling device 90. When the rotor shaft 3 is qualified, the flipping robot 662 picks it up and places it on the transfer platform 663. The transfer platform 663 horizontally transfers the rotor shaft 3 to the pressing station 50. The pressing device 52 on the pressing station 50 presses the rotor shaft 3 into the rotor core 1. After the pressing operation at the pressing station 50, the rotor core 1 needs to be further inspected. For rotor cores 1 that are not qualified by pressing, they are picked up by the fourth picking device 103 and placed in the unqualified area. For qualified rotor cores 1, they are picked up and placed in the qualified area, thus completing the assembly of the rotor core 1.

Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
