Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a rotor magnetic sheet attachment assembly. Background Technology
[0002] In the structure of an electric motor, the rotor is the core component, and its performance directly determines the overall efficiency of the motor. The quality of the attachment of the rotor magnetic sheets has a key impact on the rotor's performance. Precise attachment of the magnetic sheets can ensure the uniform distribution of the magnetic field, thereby improving the motor's torque output and efficiency, and reducing energy consumption and noise.
[0003] Application No. 202122452670.5 relates to a magnetic sheet attaching machine for an external rotor brushless motor, comprising a feeding mechanism, a guiding mechanism, and a pushing mechanism. The feeding mechanism includes a feeding tray with several feeding grooves on its upper surface, each containing a magnetic sheet. The guiding mechanism includes a magnetic cylinder and a pressure ring. The magnetic cylinder is magnetic, and a connecting skirt is provided in its lower part, which is fixed to the feeding tray by bolts. Several partitions are provided on the side wall of the magnetic cylinder, forming several sliding grooves. The sliding grooves correspond one-to-one with the feeding grooves in position and number. The pressure ring is sleeved on the magnetic cylinder and fixed to the feeding tray. The pushing mechanism includes a pusher plate, which is disposed in the sliding groove. The pushing mechanism pushes the pusher plate to push the magnetic sheet out of the sliding groove and adsorbs it onto the inner wall of the iron ring to which the magnetic sheet is to be attached. The pusher plate pushes the magnetic sheet located in the inner layer to the outside of the feeding groove, and then adsorbs it into the iron ring, which is both precise and efficient.
[0004] The above solution has shortcomings in use. When the pusher pushes the magnetic sheet from the feeding groove into the chute, it is difficult to ensure that the magnetic sheet moves forward automatically and stably in the feeding groove to reach the designated position for the pusher to move up and down. The magnetic sheet may get stuck or deviate in the feeding groove due to uneven friction, and cannot smoothly reach the pusher's stroke range, resulting in an increase in the pusher's idle stroke, which affects the magnetic sheet adhesion effect. To address this, we provide a rotor magnetic sheet adhesion component. Utility Model Content
[0005] This utility model provides a rotor magnetic sheet attachment assembly that can apply a pushing force to the magnetic sheet inside the feeding trough to make it move forward steadily and continuously, ensuring that the magnetic sheet can smoothly travel within the pushing stroke range, and further ensuring the effect of magnetic sheet attachment.
[0006] The purpose and effect of this utility model of a rotor magnetic sheet attaching assembly are achieved by the following specific technical means: A rotor magnetic sheet attaching assembly includes a material tray, material grooves arranged in a ring on the material tray, a rotor positioning assembly disposed above the material tray, and a magnetic sheet pushing and attaching assembly disposed below the material tray, and further includes:
[0007] The magnetic sheet automatic travel assembly is set on the material tray and includes a set of guide rods fixedly connected to the bottom of the material tray, an L-shaped plate slidably connected to the outside of each guide rod, a tension spring sleeved on the outside of each guide rod, and a push plate set on each L-shaped plate and located inside the material groove for pushing the magnetic sheet forward.

[0009] Preferably, the rotor positioning assembly further includes an I-shaped frame fixedly connected to the upper surface of the material tray, an electric push rod is installed on the bottom surface of the I-shaped frame, and a pressure plate is installed on the telescopic end of the electric push rod.
[0010] Preferably, the magnetic sheet pushing and attaching assembly includes a through slot adapted to the magnetic sheet inside each material trough and a hydraulic push rod disposed below the material tray, wherein the telescopic end of the hydraulic push rod is equipped with a set of top plates adapted to the through slot.
[0011] Preferably, a U-shaped frame is installed at the bottom end of the hydraulic push rod, and the top end of the U-shaped frame is connected to the bottom surface of the material tray.
[0012] Preferably, one end of each tension spring is connected to the L-shaped plate, and the other end of each tension spring is connected to the end of the guide rod located below the material tray.
[0013] Preferably, each of the L-shaped plates has a baffle rotatably connected to its upper surface, and each baffle has an anti-collision pad on the side near the material tray.
[0014] Preferably, a circular plate is fixedly connected to the other end of each guide rod.

[0017] Beneficial effects:
[0018] 1. The set magnetic sheet automatic travel component can apply a continuous pushing force to the magnetic sheet inside the material tank. After the top plate pushes the magnetic sheet to complete the attachment and reset, the push plate will push the magnetic sheet to travel inside the material tank, which can ensure that the magnetic sheet arrives smoothly above the top plate and avoid the situation of empty travel when the top plate moves up, thus further ensuring the effect of magnetic sheet attachment.
[0019] 2. The L-shaped plate can be held outside the material tray by the rotating plate, so that the push plate is located on the outside of the material trough, which makes it convenient for the staff to put the magnetic sheet into the material trough. The L-shaped plate can be reinforced and guided by the stabilizing holes and stabilizing rods to ensure that the L-shaped plate can push the push plate to move steadily. The push plate can then push the magnetic sheet to move accurately along the preset path. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0029] First Embodiment
[0030] As attached Figure 1 With appendix Figure 2 As shown: A rotor magnetic sheet attaching assembly includes a material tray 1 and a material groove 2 arranged in a ring on the material tray 1. The size of the material groove 2 is adapted to the size of the attached magnetic sheet. A ring-arranged support column 6 is fixedly connected to the bottom surface of the material tray 1. The bottom end of a group of support columns 6 is fixedly connected to a ring base 7. By using the cooperation between the support column 6 and the ring base 7, a stable support can be formed for the material tray 1.
[0031] The rotor positioning assembly 3 is located above the material tray 1. The rotor positioning assembly 3 includes a positioning disk 301 located on the upper surface of the material tray 1. A set of through slots 302 adapted to the magnetic sheet are opened on the upper surface of the positioning disk 301. The positioning disk 301 can be used to position the rotor so that the position of the magnetic sheet attached to the outside of the rotor is aligned with the through slots 302.
[0032] The rotor positioning assembly 3 also includes an I-shaped frame 303 fixedly connected to the upper surface of the material tray 1. An electric push rod 304 is installed on the bottom surface of the I-shaped frame 303. A pressure plate 305 is installed on the telescopic end of the electric push rod 304. The operation of the electric push rod 304 can push the pressure plate 305 down, and the pressure plate 305 will press the rotor down, thereby stabilizing the rotor, which is beneficial for subsequent attachment of magnetic sheets.
[0033] Second Embodiment
[0034] As attached Figure 1 Appendix Figure 3 With appendix Figure 4 As shown: A magnetic sheet pushing and attaching assembly 4 is set below the material tray 1. The magnetic sheet pushing and attaching assembly 4 includes a through groove 401 adapted to the magnetic sheet and opened inside each material slot 2, and a hydraulic push rod 402 set below the material tray 1. The telescopic end of the hydraulic push rod 402 is equipped with a set of top plates 403 adapted to the through groove 401. By extending the hydraulic push rod 402, the top plate 403 can be pushed upward to pass through the through groove 401. The top plate 403 will then push the magnetic sheet inside the material slot 2 through the through groove 302 and attach it to the outside of the rotor, thus completing the attachment of the magnetic sheet on the outside of the rotor. A U-shaped frame 404 is installed at the bottom end of the hydraulic push rod 402. The top end of the U-shaped frame 404 is connected to the bottom surface of the material tray 1. The U-shaped frame 404 can support and fix the hydraulic push rod 402, so that it is in a stable state during operation.
[0035] Third Embodiment
[0036] As attached Figure 1 Appendix Figure 5 With appendix Figure 6As shown: The magnetic sheet automatic moving assembly 5 is set on the material tray 1, including a set of guide rods 501 fixedly connected to the bottom of the material tray 1, an L-shaped plate 502 slidably connected to the outside of each guide rod 501, a tension spring 503 sleeved on the outside of each guide rod 501, and a push plate 504 set on each L-shaped plate 502 and located inside the material trough 2 for pushing the magnetic sheet forward. One end of each tension spring 503 is connected to the L-shaped plate 502. When the top plate 403 is reset, the tension spring 503 continuously applies a holding force to the L-shaped plate 502. The L-shaped plate 502 will push the push plate 504, which will push the magnetic sheet to move steadily inside the material tray 2, so that the magnetic sheet can move steadily to the forming range of the top plate 403, so as to avoid the empty stroke when the top plate 403 moves upward, and further ensure the adhesion effect of the magnetic sheet. The other end of each tension spring 503 is connected to the end of the guide rod 501 located below the material tray 1. One end of the tension spring 503 is stable at one end of the guide rod 501. After the tension spring 503 is extended, its other end will apply a stable holding force to the L-shaped plate 502.
[0037] Each L-shaped plate 502 has a baffle 505 rotatably connected to its upper surface. Each baffle 505 has an anti-collision pad on the side near the material tray 1. The baffle 505 can hold the L-shaped plate 502 on the material tray 1, so that the push plate 504 is located on the side of the material trough 2 near the outside of the material tray 1, which makes it convenient for the staff to place magnetic sheets into the material trough 2. The other end of each guide rod 501 is fixedly connected to a circular plate 506. The circular plate 506 can block the L-shaped plate 502 and prevent the L-shaped plate 502 from separating from the guide rod 501.
[0038] The magnetic sheet automatic travel assembly 5 also includes multiple sets of stabilizing holes 507 formed on the outer surface of the tray 1. Each stabilizing hole 507 has a slidably connected stabilizing rod 508 on its inner wall. The other end of each stabilizing rod 508 is connected to the outer surface of each L-shaped plate 502. By using the cooperation between the stabilizing rod 508 and the stabilizing hole 507, the L-shaped plate 502 can be guided and stabilized, thereby enabling the pusher plate 504 to push the magnetic sheet to move precisely along the preset path.
[0039] Working principle: First, the rotor with external adhesive coating is installed on the positioning plate 301. Then, the electric push rod 304 is extended, and the holding plate 305 descends to hold the rotor stably. Then, the magnetic sheets are placed in the material groove 2 in sequence. Then, the baffle 505 is rotated to separate it from the material plate 1. At this time, the tension spring 503 pulls the L-shaped plate 502, and the L-shaped plate 502 applies a pushing force to the push plate 504. The push plate 504 will continuously push the magnetic sheets. At the same time, the hydraulic push rod 402 is extended, and the top plate 403 moves up and passes through the through groove 401. The magnetic sheets will then be pushed upward and pass through the through groove 302 to attach to the outside of the rotor. When the top plate 403 descends and resets, the push plate 504 will push the magnetic sheets to move inside the material groove 2, which can stably move the subsequent magnetic sheets above the top plate 403. This can avoid the situation of empty stroke when the top plate 403 moves up and pushes the magnetic sheets, and further ensure the effect of magnetic sheet attachment.
