Description

Technical Field

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

[0002] In the precise structural system 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 fit together to form the core rotating component. In the motor manufacturing process, after the iron core and shaft are assembled to form the rotor, a pushing mechanism precisely pushes the formed rotor onto the unloading track. However, due to the speed and inertia during the pushing process, the rotor experiences a strong collision upon contact with the unloading track. The impact force generated by this collision easily acts on the edges and corners of the iron core, causing deformation. The deformation of the iron core edges and corners directly affects the overall performance and specifications of the rotor, thus significantly reducing the rotor's production yield. Therefore, it is necessary to develop a stable iron core feeding device to solve the above problems. Utility Model Content

The electromagnet is energized and generates magnetism. The arc-shaped part at the front end of the electromagnet matches the outline of the iron core and magnetically attracts the iron core on the rotor. The electromagnet moves backward and moves the rotor into the longitudinal track. The lower end of the shaft corresponds to the longitudinal slot. When the shaft moves to the rear end of the longitudinal slot, the electromagnet is de-energized and continues to move backward under the drive of the longitudinal cylinder. The rotor stops at the junction of the longitudinal slot and the transverse slot. Then, the transverse cylinder drives the unloading pusher to move to the right and pushes the rotor to the right end of the transverse track. The lower end of the shaft corresponds to the transverse slot. On the transverse track and the unloading track, the rotor of the next set pushes the rotor of the previous set to move to the right, thereby unloading along the unloading track. The advantage of this design is that during the feeding process, the rotor is moved into the longitudinal and transverse tracks for horizontal transport, and then fed out from the feeding track. Throughout the feeding process, the rotor moves smoothly, avoiding violent collisions during feeding, ensuring the quality and specifications of the iron core are stable, and improving the production qualification rate.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1 to 6As shown, a stable iron core feeding device includes a frame 1, a conveying mechanism 2, an iron core unloading mechanism 3, a rotating shaft unloading mechanism 4, a shaft feeding mechanism 5, and a rotor feeding mechanism 6. The conveying mechanism 2 is fixed above the frame 1. The iron core unloading mechanism 3 and the rotating shaft unloading mechanism 4 are both fixed on the frame 1 and respectively mounted on the left and right sides above the conveying mechanism 2. The shaft feeding mechanism 5 is mounted above the conveying mechanism 2 and corresponds between the iron core unloading mechanism 3 and the rotating shaft unloading mechanism 4. The rotor feeding mechanism 6 includes a feeding base 61, a transverse track 62, a longitudinal track 63, a transverse cylinder 64, a longitudinal cylinder 65, a feeding pusher 66, an electromagnet 67, and a feeding track 68. The feeding base 61 is fixed on the frame 1, and the transverse track 62 and the longitudinal track 68 are fixed on the frame 1. All tracks 63 are fixed on the feeding base 61 and are interconnected in the middle. The bottom inner side of the transverse track 62 is provided with a transverse groove 621, and the bottom inner side of the longitudinal track 63 is provided with a longitudinal groove 631. The front end of the longitudinal groove 631 corresponds to the shaft insertion mechanism 5, and the rear end is connected to the middle of the transverse groove 621. The transverse cylinder 64 and the feeding track 68 are respectively fixed at the left and right ends of the transverse track 62. The feeding track 68 is provided with a feeding groove 681. The left end of the feeding groove 681 is connected to the transverse groove 621. The longitudinal cylinder 65 is fixed at the rear end of the longitudinal track 63. The left end of the feeding push block 66 is fixed to the power output end of the transverse cylinder 64 and the right end is provided with an arc-shaped part. The rear end of the electromagnet 67 is fixed to the power output end of the longitudinal cylinder 65 and the front end is provided with an arc-shaped part.

[0023] The conveying mechanism 2 alternately retrieves iron cores and shafts from the iron core unloading mechanism 3 and the shaft unloading mechanism 4, and alternately transports them to the assembly station. The shaft insertion mechanism 5 assembles the iron cores and shafts at the assembly station. After assembly, the longitudinal cylinder 65 drives the electromagnet 67 forward to approach the rotor. The electromagnet 67 is energized and generates magnetism. The arc-shaped part at the front end of the electromagnet 67 matches the contour of the iron core and magnetically attracts the iron core on the rotor. The electromagnet 67 moves backward and moves the rotor into the longitudinal track 63. The lower end of the shaft corresponds to the longitudinal groove 6. Within section 31, when the rotating shaft moves to the rear end of the longitudinal slot 631, the electromagnet 67 is de-energized and continues to move backward under the drive of the longitudinal cylinder 65. The rotor then stops at the junction of the longitudinal slot 631 and the transverse slot 621. Next, the transverse cylinder 64 drives the unloading pusher 66 to move to the right, pushing the rotor to the right end of the transverse track 62. The lower end of the rotating shaft corresponds to the transverse slot 621. On the transverse track 62 and the unloading track 68, the latter group of rotors pushes the former group of rotors to move to the right, thus unloading along the unloading track 68. The advantage of this design is that during the unloading process, the rotor is transferred into the longitudinal track 63 and the transverse track 62 for translational conveying, and then unloaded from the unloading track 68. Throughout the unloading process, the rotor moves smoothly, avoiding violent collisions during unloading, ensuring the quality and specifications of the iron core are stable, and improving the production qualification rate.

[0024] The rotor feeding mechanism 6 also includes a limiting top plate 69, which is fixed to the power transmission end of the longitudinal cylinder 65 and corresponds to the top of the electromagnet 67. L-shaped grooves 691 are provided on both the left and right sides below the limiting top plate 69, and the two sets of L-shaped grooves 691 are arranged facing each other.

[0025] When the electromagnet 67 picks up the rotor, the L-shaped slots 691 on the left and right sides correspond to the upper left and right sides of the overlapping iron core, limiting the rotor and preventing it from swinging during movement. When the rotor reaches the junction of the transverse slot 621 and the longitudinal slot 631, at the instant the electromagnet 67 separates from the rotor, the limiting top plate 69 is still above the rotor and limits the rotor, preventing the rotor position from shifting at the instant the electromagnet 67 separates.

[0026] 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. 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 power output end of the X-axis drive assembly 22 and is slidably connected to the X-axis slide 21. The core receiving block 24 and the shaft receiving block 25 are respectively fixed to the middle and right ends of the transfer platform 23. The transfer platform 23 is vertically provided with an assembly hole 231 and a shaft dropping hole 232. The core receiving block 24 and the shaft receiving block 25 are vertically provided with a first receiving hole 241 and a second receiving hole 251, respectively. The first receiving hole 241 and the second receiving hole 251 correspond to the top of the assembly hole 231 and the shaft dropping hole 232, respectively. The core dropping structure and the shaft dropping mechanism 4 are respectively fixedly mounted on the frame 1. Above the 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, 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, and 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, and the upper end of the shaft insertion pressure rod 57 corresponds to the shaft placement hole 561.

[0027] 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 feeding platform 23 moves to the right, and the iron core falls into the assembly hole 231. Meanwhile, the rotating shaft receiving block 25 continues to receive a rotating 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 rotating shaft is inserted into the iron core. After the upper end of the rotating shaft passes through all the iron cores, it is aligned with the clearance hole, thus completing the assembly of the rotor. Then, the limiting pressure rod 53 rises, and the magnetic suction component 54 raises the rotor through magnetic attraction. Finally, the electromagnet 67 picks up the rotor and discharges it from the rotor unloading mechanism 6.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.
