Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology of motor rotors, and in particular to a device for inserting a micro motor core onto a shaft. Background Technology

[0002] In the intricate structure of a motor rotor, the cylindrical shaft acts as the "spine" running through the central core, vertically penetrating the central hole of the iron core, which is made of neatly stacked silicon steel sheets. The two precisely mate to form the core rotating component. However, in traditional automated production equipment, the assembly process of the iron core and shaft faces numerous bottlenecks: constrained by mechanical design limitations, the production line is equipped with two large handling mechanisms. A cantilevered robotic arm is responsible for gripping the cylindrical iron core, while a gantry system is specifically used to transport the slender shaft. These two sets of equipment operate in parallel but independently, occupying a large amount of production space, resulting in a cumbersome and chaotic production line layout. Furthermore, due to a lack of coordination in the handling path planning, frequent equipment interference and waiting occur, making the iron core and shaft highly susceptible to collision damage during transport. This further increases overall production costs and becomes a key technological bottleneck restricting the efficient production of motors. Therefore, it is necessary to develop a miniature motor iron core insertion device to solve these problems. Utility Model Content

[0007] Further description of the present invention: The rotating shaft unloading mechanism includes a rotating shaft hopper, a sliding seat, an X-axis cylinder, a pusher plate, and a guide assembly. The rotating shaft hopper is fixedly mounted on the right side of the transfer platform.

The sliding seat and the X-axis cylinder are both fixed on the rotating shaft hopper. The left end of the sliding seat corresponds to the lower part of the first unloading chamber. The right end of the pusher plate is fixed to the power output end of the X-axis cylinder.

Vertically stacked iron cores are placed in the iron core unloading mechanism, and a rotating shaft is placed in the rotating shaft unloading mechanism. When the transfer platform moves to the right, the rotating shaft unloading mechanism vertically drops a rotating shaft into the second receiving hole, and then into the shaft dropping hole.

At this time, the iron core receiving block is exactly below the iron core unloading mechanism, and the iron core falls into and fills the first receiving hole. The transfer platform... The platform moves to the right, and the iron core falls into the assembly hole. Meanwhile, the shaft receiving block continues to receive one shaft. At this point, the first Z-axis drive assembly drives the limiting pressure rod to descend, aligning the magnetic suction component with the first receiving hole and above the assembly hole. The second Z-axis drive assembly drives the shaft receiving pressure rod to rise, inserting the shaft into the iron core. The upper end of the shaft passes through all the iron cores and aligns with the clearance hole, thus completing the rotor assembly. Next, the limiting pressure rod rises, and the magnetic suction component lifts the rotor through magnetic attraction. Finally, the rotor unloading mechanism unloads the assembled rotor and begins the next cycle. The advantages of this design are: by setting up a transfer platform, it combines the functions of conveying iron cores and shafts, simplifying the structure, reducing equipment costs, and improving assembly efficiency. Furthermore, the fixed distance between the iron core receiving block and the shaft receiving block prevents interference during the conveying of iron cores and shafts, ensuring stable equipment operation.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1 to 6As shown, a micro motor core feeding device includes a frame 1, a conveying mechanism 2, a core unloading mechanism 3, a shaft unloading mechanism 4, a shaft feeding mechanism 5, and a rotor unloading mechanism 6. The conveying mechanism 2 includes an X-axis slide 21, an X-axis drive assembly 22, a transfer platform 23, a core receiving block 24, and a shaft receiving block 25. The X-axis slide 21 is fixed on the frame 1, and the X-axis drive assembly 22 is fixed on the frame 1 and corresponds to the left side of the X-axis slide 21. The left end of the transfer platform 23 is fixed to the X-axis drive assembly 25. The power output end of the moving component 22 is slidably connected to the X-axis slide table 21. The iron core receiving block 24 and the rotating shaft receiving block 25 are respectively fixed in the middle and right end of the transfer platform 23. The transfer platform 23 is vertically provided with an assembly hole 231 and a shaft drop hole 232. The iron core receiving block 24 and the rotating shaft receiving block 25 are respectively vertically provided with a first receiving hole 241 and a second receiving hole 251. The first receiving hole 241 and the second receiving hole 251 are respectively above the assembly hole 231 and the shaft drop hole 232. The material feeding structure and the rotating shaft material feeding mechanism 4 are respectively fixedly mounted above the iron core receiving block 24 and the rotating shaft receiving block 25. The shaft insertion mechanism 5 includes a mounting frame 51, a first Z-axis drive assembly 52, a limiting pressure rod 53, a magnetic suction component 54, a second Z-axis drive assembly 55, a shaft placement block 56, and a shaft insertion pressure rod 57. The mounting frame 51 is fixed above the frame 1, the first Z-axis drive assembly 52 is fixed on the mounting frame 51, and the upper end of the limiting pressure rod 53 is fixed to the power output end of the first Z-axis drive assembly 52. The magnetic suction component 54 is fixed to the lower end of the limiting pressure rod 53. The magnetic suction component 54 has a clearance hole in the middle. The second Z-axis drive assembly 55 is fixed on the frame 1. The shaft placement block 56 is fixed on the frame 1 and corresponds to the lower part of the magnetic suction component 54. The shaft placement block 56 has a vertical shaft placement hole 561. The lower end of the shaft insertion pressure rod 57 is fixed to the power output end of the second Z-axis drive assembly 55. The upper end of the shaft insertion pressure rod 57 corresponds to the shaft placement hole 561. The rotor feeding mechanism 6 is fixedly set on one side of the pressure rod.

[0022] The X-axis drive assembly 22 drives the transfer platform 23 to move left and right on the X-axis slide 21. Vertically stacked iron cores are placed in the iron core unloading mechanism 3, and rotating shafts are placed in the rotating shaft unloading mechanism 4. When the transfer platform 23 moves to the right, the rotating shaft unloading mechanism 4 vertically drops a rotating shaft into the second receiving hole 251, and then into the shaft dropping hole 232. Next, the transfer platform 23 moves to the left, aligning the shaft dropping hole 232 with the shaft placement block 56 above it. The rotating shaft then falls into the shaft placement hole 561. At this time, the iron core receiving block 24 is exactly below the iron core unloading mechanism 3, and the iron core falls into the first receiving hole 241, filling it completely. The transfer platform 22... 3. Moving to the right, the iron core falls into the assembly hole 231, while the shaft receiving block 25 continues to receive one shaft. At this time, the first Z-axis drive assembly 52 drives the limiting pressure rod 53 to descend, so that the magnetic suction component 54 is aligned with the first receiving hole 241 and above the assembly hole 231. The second Z-axis drive assembly 55 drives the shaft insertion pressure rod 57 to rise, so that the shaft is inserted into the iron core. After the upper end of the shaft passes through all the iron cores, it is aligned with the clearance hole, thus completing the rotor assembly. Then, the limiting pressure rod 53 rises, and the magnetic suction component 54 raises the rotor through magnetic attraction. Finally, the rotor unloading mechanism 6 unloads the assembled rotor and starts the next cycle. The advantages of this design are: by setting the transfer platform 23, which has the function of conveying both iron cores and shafts, the structure is simplified, which not only reduces equipment costs but also improves assembly efficiency. On the other hand, the distance between the iron core receiving block 24 and the shaft receiving block 25 is fixed, so there will be no interference during the conveying of iron cores and shafts, ensuring the stable operation of the equipment.

[0023] The iron core unloading mechanism 3 includes a mounting base 31, an iron core storage column 32, a limiting block 33, and a suspension plate 34. The mounting base 31 is fixedly mounted on the left side of the transfer platform 23. The iron core storage column 32 and the limiting block 33 are both fixed on the mounting base 31 and are both above the transfer platform 23. The iron core storage column 32 has a storage cavity 321 in the middle. The right end of the iron core storage column 32 has an opening communicating with the storage cavity 321. The limiting block 33 is located to the right of the opening. The right end of the suspension plate 34 is fixed on the mounting frame 51. The left end of the suspension plate 34 is located above the iron core storage column 32. The left end of the suspension plate 34 has a suspension groove 341.

[0024] After the iron cores are manufactured in the previous process, they are strung together with metal strips to keep them neatly stacked. When feeding the iron cores, the iron cores are placed into the storage cavity 321. The upper end of the metal strip is fixed in the suspension groove 341 on the suspension plate 34, so that when the first receiving hole 241 receives the iron cores, the metal strip will not fall into the first receiving hole 241. The lower end of the iron core storage column 32 will block the iron cores above the first receiving hole 241, thereby ensuring that the first receiving hole 241 delivers a specific number of iron cores. The limiting block 33 further plays a blocking role to prevent the iron cores from jumping to the left after passing the lower end of the iron core storage column 32 due to their thinness.

[0025] The rotating shaft unloading mechanism 4 includes a rotating shaft hopper 41, a sliding seat 42, an X-axis cylinder 43, a pusher plate 44, and a guide assembly 45. The rotating shaft hopper 41 is fixedly mounted on the right side of the transfer platform 23. From top to bottom, the rotating shaft hopper 41 has an interconnected feeding hopper 411, a first unloading chamber 412, and a second unloading chamber 413. The sliding seat 42 and the X-axis cylinder 43 are both fixed on the rotating shaft hopper 41. The left end of the sliding seat 42 corresponds to the first unloading chamber 412. Below, the right end of the pusher plate 44 is fixed to the power output end of the X-axis cylinder 43. The left end of the pusher plate 44 passes through the lower end of the first dropping chamber 412 and the upper end of the second dropping chamber 413 in sequence. The left end of the pusher plate 44 has a limiting dropping hole 441. The guide assembly 45 is fixed on the rotating shaft hopper 41 and corresponds to the lower end of the second dropping chamber 413. The lower end of the guide assembly 45 has a rotating shaft loading hole 4512 corresponding to the upper part of the second receiving hole 251.

[0026] The rotating shafts are stacked in batches in the feeding bin 411 and stacked vertically in the first dropping chamber 412. The rotating shaft at the bottom of the first dropping chamber 412 falls into the limiting dropping hole 441 and is placed above the sliding seat 42. The limiting dropping hole 441 can only accommodate one rotating shaft. Then, the X-axis cylinder 43 drives the pusher plate 44 to move to the left. The rotating shaft in the limiting dropping hole 441 is disengaged from the sliding seat 42 and falls into the guide assembly 45 from the second dropping chamber 413. The guide assembly 45 guides the rotating shaft so that it falls vertically into the second receiving hole 251.

[0027] The material guiding assembly 45 includes a material guiding plate 451, a cover plate 452, and a deflecting protrusion 453. The material guiding plate 451 is fixed on the rotating shaft hopper 41, and the cover plate 452 is fixed on one side of the material guiding plate 451. The material guiding plate 451 has a material guiding cavity 4511 inside. The upper end of the material guiding cavity 4511 corresponds to the lower part of the second discharge cavity 413. The lower side of the material guiding cavity 4511 is V-shaped. The middle part of the lower end of the material guiding cavity 4511 has a rotating shaft loading hole 4512. The deflecting protrusion 453 is fixed on the material guiding plate 451 and corresponds to the upper side of the material guiding cavity 4511. The deflecting protrusion 453 corresponds to the side above the rotating shaft loading hole 4512.

[0028] When the shaft falls into the guide cavity 4511, one end of the shaft will touch the deflection protrusion 453, thereby deflecting the shaft from the horizontal direction by a certain angle, preventing the shaft from spanning the lower side of the guide cavity 4511. After deflection, the shaft is guided by the V-shaped structure on the lower side of the guide cavity 4511, so that the shaft falls vertically from the shaft loading hole 4512 into the second receiving hole 251.

[0029] The rotor unloading mechanism 6 includes a Y-axis cylinder 61, a pusher spring 62, an unloading track 63, and a buffer rotating plate 64. The Y-axis cylinder 61 is fixed on the frame 1 and corresponds to the rear side of the limiting pressure rod 53. The pusher spring 62 is fixed on the power output end of the Y-axis cylinder 61 and corresponds to the top of the transfer platform 23. The unloading track 63 is fixed on the frame 1 and corresponds to the front side of the limiting pressure rod 53. The buffer rotating plate 64 is rotatably mounted above the unloading track 63.

[0030] After the assembled rotor is lifted by the magnetic suction component 54, the Y-axis cylinder 61 drives the pusher 62 to push the rotor to the lower feed track 63. After the rotor is separated from the magnetic suction component 54 and touches the buffer plate 64, it falls onto the feed track 63 and is transported to the next process through the feed track 63.

[0031] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
