Description

Technical Field

[0001] This application relates to the field of stator and rotor lamination processing, and in particular to a stator and rotor lamination separation device. Background Technology

[0002] Stator laminations, also known as stator laminations, are made by stamping 0.3mm silicon steel sheets into laminations of different specifications to suit the stators of motors with different power ratings. Rotor laminations are used to combine and overlap to form the iron core.

[0003] Chinese utility model patent publication number CN203437340U discloses a rotor lamination and stator lamination screening and separation device, including a slide rail and a support column fixedly connected to the slide rail for supporting the slide rail; the slide rail is provided with a material discharge hole for screening and separating rotor laminations and stator laminations; the slide rail includes a material inlet and a material outlet; the support column includes a front support column and a rear support column, the height of the front support column is higher than the height of the rear support column; the slide rail is inclined to the ground.

[0004] In actual use, when the rotor and stator laminations move from the stamping device to the slide, there is a positional misalignment between them. The tilting and misalignment of the stator laminations can easily cause their outer walls to collide with the walls of the discharge holes, resulting in jamming during the movement of the stator laminations. This situation can easily affect the subsequent screening of the stator and rotor laminations and needs to be improved. Summary of the Invention

[0005] In order to reduce the impact of stator lamination jamming during stator lamination movement on the screening of stator and rotor laminations, this application provides a stator and rotor lamination separation device.

[0006] This application provides a stator lamination and rotor lamination separation device, which adopts the following technical solution:

[0007] A stator lamination and rotor lamination separation device includes a separation frame and a conveying frame. A separation zone is provided between the separation frame and the conveying frame for the rotor laminations to enter. The height of the end of the separation frame away from the conveying frame is higher than the height of the end of the separation frame near the conveying frame. The extension direction of the separation frame is towards the conveying frame. The separation frame is provided with limiting protrusions, the extension direction of which is parallel to the extension direction of the separation frame. There are two limiting protrusions, the distance between the two limiting protrusions is less than the diameter of the stator lamination, and the distance between the two limiting protrusions is greater than the diameter of the rotor lamination. The separation frame is provided with a sliding plate that slides along the limiting protrusions, the sliding direction of which is the extension direction of the limiting protrusions. The separation plate is located on the side of the limiting protrusions near the conveying frame. When the stator laminations slide along the limiting protrusions, the separation plate causes the stator laminations to move to the conveying frame.

[0008] By adopting the above technical solution, limiting protrusions are set to separate the stator laminations and rotor laminations. Since the diameter of the rotor lamination is smaller than the distance between the two limiting protrusions, the rotor lamination slides between the two limiting protrusions during this process. However, since the diameter of the stator lamination is larger than the distance between the two limiting protrusions, the stator lamination slides on the end face of the limiting protrusion. In this way, the stator laminations and rotor laminations are initially separated. When the stator laminations and rotor laminations pass through the separation zone, it is difficult for them to interfere with each other and affect the separation of the stator laminations and rotor laminations, making the separation operation of the stator laminations and rotor laminations more convenient.

[0009] Optionally, the separating frame is provided with a slide rail, the extension direction of the slide rail is parallel to the extension direction of the separating frame, and the separating plate is provided with a guide hole. When the stator lamination passes through the guide hole, the stator lamination slides along the extension direction of the slide rail.

[0010] By adopting the above technical solution, and setting up slide rails and guide holes, after the stator laminations move to the separation plate, the stator laminations pass through the guide holes and slide along the slide rails. This method reduces the contact between the stator laminations and the separation area, reduces the possibility of the stator laminations getting stuck, facilitates the separation area to accommodate the rotor laminations, and facilitates the separation of the rotor laminations from the stator laminations.

[0011] Optionally, the separating plate is provided with a baffle located on the side of the guide hole near the conveyor frame, and the baffle extends away from the separating plate in a direction away from the conveyor frame.

[0012] By adopting the above technical solution, in actual use, there are situations where the stator laminations move too fast and slide along the surface of the separation plate without passing through the guide holes, or the stator laminations change from sliding along the surface of the separation plate to sliding along the extension direction of the slide rail, causing damage to the slide rail. Both of these situations will affect the movement of the stator laminations toward the conveyor frame. Therefore, baffles are set up to provide auxiliary guidance and reduce the speed of the stator laminations to a certain extent, making it easier for the stator laminations to enter the slide rail, and making the separation of the stator laminations from the rotor laminations more convenient.

[0013] Optionally, a mounting base is provided on one side of the separation frame, and the mounting base is equipped with an electromagnet and a control switch. The electromagnet is located above the separation area, and the control switch controls the opening and closing of the electromagnet.

[0014] By adopting the above technical solution, in the actual operation of separating stator and rotor laminations, there is a situation where the rotor laminations are located above the stator laminations when they enter the separation frame. In this case, the rotor laminations will move towards the conveyor frame along with the stator laminations. Since the rotor laminations are often made of silicon steel sheets, which have a certain degree of magnetism, an electromagnet is set up to attract the rotor laminations located on the upper surface of the stator laminations. This reduces the situation where the rotor laminations enter the conveyor frame along with the stator laminations, thus facilitating the separation of the rotor and stator laminations.

[0015] Optionally, the separating frame is provided with a crossbar located above the separating frame. The sliding plate is provided with a control component that rotates around the crossbar, with the axis of rotation of the control component aligned with the axis of the crossbar. The control component is connected to a control rod, which is used to actuate a control switch. When the sliding plate moves toward the separating plate, the control rod activates the control switch, and the electromagnet attracts the rotor blades. When the sliding plate moves away from the separating plate, the control rod deactivates the control switch, and the electromagnet loses its magnetism.

[0016] By adopting the above technical solution, the sliding plate is used to receive stator and rotor laminations moving from the stamping die to the separation frame. When the sliding plate moves away from the separation plate, it needs to receive the stator and rotor laminations. At this time, the electromagnet does not need to perform the operation of attracting rotor laminations. The closing of the control switch causes the electromagnet to lose its magnetism, so the previously attracted rotor laminations fall off and move to the separation area. When the sliding plate moves closer to the separation plate, the control switch is opened, causing the electromagnet to attract the rotor laminations, which improves the efficiency of separating rotor and stator laminations and facilitates the separation of rotor and stator laminations.

[0017] Optionally, the electromagnet is provided with a guide plate, which is located on the side of the electromagnet away from the conveyor frame. The guide plate extends in the direction away from the electromagnet toward the direction closer to the conveyor frame. The guide plate is provided with a driving member and an extension plate. The extension plate slides on the guide plate, and the sliding direction of the extension plate is the extension direction of the guide plate. The driving member drives the extension plate to move.

[0018] By adopting the above technical solution, when the control switch is closed and the rotor blades separate from the electromagnet, the rotor blades fall into the separation zone. However, during the fall, there is a possibility that the outer wall of the rotor blades may collide with the object, which can easily cause damage to the outer wall of the rotor blades. Therefore, a guide plate is set up so that when the control switch is closed and the rotor blades separate from the electromagnet, the rotor blades move along the guide plate, reducing the possibility of damage to the outer wall of the rotor blades when they fall.

[0019] Optionally, the control switch has an open position, a middle position, and a closed position. When the control lever moves the control switch to the middle position, the side of the electromagnet away from the guide plate loses its magnetism, and the side of the electromagnet close to the guide plate attracts the rotor blades.

[0020] By adopting the above technical solution, the control switch is set to include three positions: open, intermediate, and closed. When the control switch is in the intermediate position, the electromagnet's attraction to the rotor blades is reduced, and because the side of the electromagnet away from the guide plate loses its magnetism, the rotor blades tend to tilt towards the guide plate, which reduces the impact damage to the outer wall of the rotor blades caused by the vertical fall of the rotor blades when the control switch is moved to the closed position.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Setting limiting protrusions for separating stator and rotor laminations. When moving to the separation frame, the rotor laminations slide between the two limiting protrusions; since the diameter of the stator laminations is larger than the distance between the two limiting protrusions, the stator laminations slide on the end face of the limiting protrusions. This method achieves initial separation of stator and rotor laminations. When the stator and rotor laminations pass through the separation zone, they are less likely to interfere with each other, making the separation operation more convenient.

[0023] 2. An electromagnet is installed to attract the rotor laminations located on the upper surface of the stator laminations, reducing the occurrence of rotor laminations entering the conveyor frame along with the stator laminations and facilitating the separation of rotor laminations from stator laminations.

[0024] 3. The control switch is set to have three positions: open, intermediate, and closed. When the control switch is in the intermediate position, the electromagnet’s attraction to the rotor blades is reduced. Also, because the side of the electromagnet away from the guide plate loses its magnetism, the rotor blades tend to tilt towards the guide plate. This reduces the impact damage to the outer wall of the rotor blades caused by the vertical drop of the rotor blades when the control switch is moved to the closed position.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] This application discloses a stator lamination and rotor lamination separation device. (Refer to...) Figure 1 and Figure 2 It includes a separating frame 1 and a conveying frame 2. The separating frame 1 is used to separate stator laminations from rotor laminations and to convey the separated stator laminations toward the conveying frame 2. The conveying frame 2 is used to convey the stator laminations to subsequent processing equipment.

[0032] A separation zone 3 is provided between the separating frame 1 and the conveyor frame 2, allowing the rotor blades to enter. In actual use, a storage box is provided below the separation zone 3 to store the rotor blades. The height of the end of the separating frame 1 away from the conveyor frame 2 is higher than the height of the end of the separating frame 1 closer to the conveyor frame 2, and the extension direction of the separating frame 1 is towards the conveyor frame 2.

[0033] See Figure 2 and Figure 3 The separating frame 1 includes a body 4 and a limiting partition 5. The limiting partition 5 is located on the side wall of the body 4 and is used to prevent the stator laminations and rotor laminations from separating from the body 4. In actual use, two limiting partitions 5 are provided. The body 4 is provided with limiting protrusions 6, which are located on the upper end face of the body 4. The limiting protrusions 6 abut against the side wall of the limiting partition 5, and the extending direction of the limiting protrusions 6 is parallel to the extending direction of the separating frame 1. There are two limiting protrusions 6, and the distance between the two limiting protrusions 6 is less than the diameter of the stator laminations and greater than the diameter of the rotor laminations. The separating frame 1 is provided with a sliding plate 7, which slides on the limiting protrusions 6. The sliding direction of the sliding plate 7 is the extending direction of the limiting protrusions 6. The sliding plate 7 is used to receive the stator laminations and rotor laminations formed from the stamping die to the conveyor frame 2.

[0034] The separating frame 1 is equipped with a slide rail 8, which is located on the side of the machine body 4 near the conveyor frame 2, and the extension direction of the slide rail 8 is parallel to the extension direction of the separating frame 1. The machine body 4 is equipped with a separating plate 9, which is located on the side of the limiting protrusion 6 near the conveyor frame 2 and is located above the slide rail 8. The separating plate 9 is equipped with a guide hole 10, which passes through the separating plate 9. When the stator lamination passes through the guide hole 10, the stator lamination slides along the extension direction of the slide rail 8. The separating plate 9 is also equipped with a baffle 11, which is located on the side of the guide hole 10 near the conveyor frame 2. The baffle 11 extends away from the separating plate 9 and away from the conveyor frame 2. The baffle 11 is used to restrict the movement of the stator lamination along the end face of the separating plate 9 so that the stator lamination can pass through the guide hole 10.

[0035] A mounting base 12 is provided on one side of the separating frame 1. The mounting base 12 houses an electromagnet 13 and a control switch. The electromagnet 13 is located above the separating zone 3. The control switch controls the opening and closing of the electromagnet 13. The control switch has an open position, a neutral position, and a closed position. When the control switch is in the open position, the electromagnet 13 attracts the rotor laminations. The magnetic force of the electromagnet 13 is greater than the weight of the rotor laminations but less than the weight of the stator laminations. When the control switch is in the neutral position, the portion of the electromagnet 13 closer to the conveyor frame 2 loses its magnetic force, while the portion farther from the conveyor frame 2 attracts the rotor laminations. When the control switch is in the closed position, the electromagnet 13 loses its magnetic force.

[0036] See Figure 1 and Figure 4 The electromagnet 13 is equipped with a guide plate 14, which is located on the side of the electromagnet 13 away from the conveyor frame 2. The guide plate 14 extends from the direction away from the electromagnet 13 towards the direction closer to the conveyor frame 2. The guide plate 14 has an extension hole 15 that passes through the guide plate 14, and the direction of the extension hole 15 is the same as the direction of extension of the guide plate 14. An extension plate 16 slides along the extension hole 15, and the sliding direction of the extension plate 16 is the same as the direction of the extension hole 15. In actual use, the electromagnet 13 is also connected to a driving component 17, which is connected to the extension plate 16 and drives the extension plate 16 to move. In this embodiment, the driving component 17 is a cylinder; alternatively, the driving component 17 can also be a hydraulic cylinder.

[0037] The separating frame 1 is equipped with a support rod 18 and a crossbar 19. The support rod 18 is located on the upper surface of the separating frame 1, and the crossbar 19 is located at the end of the support rod 18 away from the separating frame 1. The sliding plate 7 is equipped with a control component 20, which rotates on the crossbar 19. The rotation axis of the control component 20 is in the direction of the axis of the crossbar 19. The control component 20 is connected to a control rod 23, which is used to actuate a control switch. In actual use, the control component 20 includes a first connecting rod 21 and a second connecting rod 22. The first connecting rod 21 is rotatably connected to the crossbar 19, and its rotation axis is in the direction of the axis of the crossbar 19. The second connecting rod 22 is located at the end of the first connecting rod 21 away from the crossbar 19. The second connecting rod 22 is hinged to the first connecting rod 21 and to the sliding plate 7.

[0038] When the sliding plate 7 moves toward the separation plate 9, the control lever 23 turns on the control switch, and the electromagnet 13 attracts the rotor blades; when the sliding plate 7 moves away from the separation plate 9, the control lever 23 turns off the control switch, and the electromagnet 13 loses its magnetism.

[0039] The implementation principle of the stator lamination and rotor lamination separation device in this application embodiment is as follows: In actual use, the sliding plate 7 receives the stator laminations and rotor laminations formed from the stamping die. Then, the sliding plate 7 moves a certain distance towards the conveyor frame 2 and stops. The stator laminations and rotor laminations move towards the conveyor frame 2, and the rotor laminations located below the stator laminations enter the separation zone 3. At this time, the sliding plate 7 causes the control lever 23 to control the control switch to open, and the electromagnet 13 attracts the rotor laminations located above the stator laminations. Subsequently, the sliding plate 7 moves away from the conveyor frame 2, and the control switch changes from the open position to the intermediate position and then the closed position. Subsequently, the rotor laminations attracted by the electromagnet 13 fall into the separation zone 3.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
