Description

Technical Field

[0001] The present application relates to the field of stator sheet and rotor sheet processing, and in particular to a stator sheet and rotor sheet screening and separation device. Background Art

[0002] The stator lamination is an important component of the motor and is usually stamped from silicon steel sheets. The main function of the silicon stator lamination is to generate a rotating magnetic field and realize the conversion of electrical energy into mechanical energy. The rotor lamination (also known as the rotor lamination) is one of the core components of the motor and is mainly used to form the rotor core structure.

[0003] Referring to the Chinese utility patent with patent number CN203437340U, a device for screening and separating rotor sheets and stator sheets is disclosed, which includes a slide and a support column fixedly connected to the slide for supporting the slide; the slide is provided with a drop hole for screening and separating rotor sheets and stator sheets; the slide includes a feed port and a discharge port, and the support column includes a front support column and a rear support column, and the height of the front support column is higher than that of the rear support column; the slide is inclined to the ground.

[0004] In actual use, when the rotor plates and stator plates are screened, there is a possibility that the rotor plates and stator plates partially overlap during movement, causing both to move together, resulting in poor screening effect, which needs to be improved. Summary of the Invention

[0005] In order to improve the screening effect of stator sheets and rotor sheets, the present application provides a stator sheet and rotor sheet screening and separation device.

[0006] The present application provides a stator and rotor sheet screening and separation device, which adopts the following technical solution:

[0007] A device for screening and separating stator sheets and rotor sheets, comprising a conveying frame, the conveying frame comprising an inclined conveying platform, the conveying platform comprising a feed side and a discharge side, the conveying platform being inclined downward along the feed side toward the discharge side, the conveying platform being provided with a blanking hole, the diameter of the blanking hole being larger than the diameter of the rotor sheet and smaller than the diameter of the stator sheet, the blanking hole being for the rotor sheet to pass through; the conveying platform being provided with a limit plate, the limit plate being located between the blanking hole and the feed side, the limit plate being inclined toward the discharge side along the direction close to the conveying platform, the side of the limit plate close to the conveying platform forming a screening gap with the conveying platform, the screening gap being for the stator sheet or rotor sheet to pass through.

[0008] By adopting the above technical solution, a screening gap is set, which is used for passing a single stator sheet or rotor sheet, thereby reducing the situation where the rotor sheet is located above the stator sheet during transportation, resulting in the rotor sheet not falling into the blanking hole, and reducing the situation where the rotor sheet is mixed with the stator sheet and affects subsequent processing, thereby facilitating the screening and separation of the rotor sheet and the stator sheet.

[0009] Optionally, a support frame is included, the support frame is provided with a driving member, the driving member is connected to a limiting plate, and the driving member drives the limiting plate to move in a direction close to or away from the conveying platform.

[0010] By adopting the above technical solution, a driving member is provided, and the screening gap size is adjusted by the driving member, which facilitates the screening of stator sheets and rotor sheets of different thicknesses and improves the overall scope of application.

[0011] Optionally, the limit plate is provided with a limit member, which is used to limit the movement of the stator sheet toward the discharge side; when the driving member drives the limit plate to move toward the conveying platform, the screening gap allows a single stator sheet or rotor sheet to pass through; when the driving member drives the limit plate to move toward the conveying platform, the limit member limits the movement of the stator sheet toward the discharge side.

[0012] By adopting the above technical solution, a limiter is provided, which is used to limit the movement of the stator sheet toward the discharge side. When the overlapping stator sheet and rotor sheet move to the position of the limiter plate, if the rotor sheet is closer to the discharge side than the stator sheet in the overlapping state, both states of the limiter plate can allow the rotor sheet to pass through and facilitate the screening of the rotor sheet and the stator sheet; in the first state: when the driving member drives the limiter plate to move in the direction close to the conveying platform, the screening gap allows the stator sheet or the rotor sheet to pass through. At this time, when the rotor sheet is below the stator sheet, the rotor sheet can pass through the screening gap, and the stator sheet is blocked and screened; at this time, when the rotor sheet is above the stator sheet, the stator sheet passes through the screening gap, the rotor sheet is screened and then moves toward the blanking hole; in the second state: when the driving member drives the limiter plate to move in the direction away from the conveying platform, the limiter limits the movement of the stator sheet toward the discharge side. At this time, the limiter blocks the movement of the stator sheet, and due to the increase in the screening gap, the rotor sheet can slide and pass through the screening gap, so it can still play a screening role.

[0013] Optionally, the limiting member includes a first limiting screw and a first limiting circular plate, the first limiting screw is threadedly connected to the first limiting plate, and the first limiting screw is rotatably connected to the conveying platform. When the first limiting plate moves toward the direction close to the conveying platform, the first limiting screw rotates; the first limiting circular plate is coaxially arranged on the first limiting screw, and the rotation of the first limiting screw drives the first limiting circular plate to rotate. The first limiting circular plate is provided with a first limiting bar, and the first limiting bar is used to resist the stator plate.

[0014] By adopting the above technical solution, a first limiting screw and a first limiting circular plate are provided, and when the limiting plate is driven to move by the driving member, the first limiting circular plate is also driven to rotate, so that the stator plate is limited by the first limiting bar, making the screening of the stator plate and the rotor plate more convenient.

[0015] Optionally, the limiting member also includes a second limiting screw and a second limiting circular plate, the second limiting screw is threadedly connected to the second limiting plate, and the second limiting screw is rotatably connected to the conveying platform. When the second limiting plate moves toward the conveying platform, the second limiting screw rotates, and the rotation directions of the first limiting screw and the second limiting screw are opposite; the second limiting circular plate is coaxially arranged on the second limiting screw, and the rotation of the second limiting screw drives the second limiting circular plate to rotate. The second limiting circular plate is provided with a second limiting bar, and the second limiting bar is used to resist the stator plate.

[0016] By adopting the above technical solution, a second limit bar is set, which is used to resist the stator sheet. By cooperating with the first limit bar, the screening efficiency of the rotor sheet and the stator sheet is further improved, and the situation of the rotor sheet mixing into the stator sheet is reduced, which facilitates subsequent processing.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. Set a screening gap. The screening gap is used to allow stator or rotor sheets to pass through. This reduces the situation where the rotor sheet is located above the stator sheet during transportation, resulting in the rotor sheet not falling into the blanking hole. It also reduces the situation where the rotor sheet mixes with the stator sheet and affects subsequent processing, and facilitates the screening and separation of the rotor sheet and the stator sheet.

[0019] 2. A limiter is provided to limit the movement of the stator sheet toward the discharge side. When the overlapping stator sheet and rotor sheet move to the position of the limiter plate, if the rotor sheet is closer to the discharge side than the stator sheet in the overlapping state, both states of the limiter plate allow the rotor sheet to pass through and facilitate the screening of the rotor and stator sheets.

[0020] 3. A first limiting screw and a first limiting circular plate are set. When the limiting plate is driven to move by the driving member, the first limiting circular plate is also driven to rotate, so that the stator plate is limited by the first limiting bar, making the screening of the stator plate and the rotor plate more convenient.

[0025] The present application is further described in detail below with reference to the accompanying drawings and examples.

[0026] The embodiment of the present application discloses a device for screening and separating stator sheets and rotor sheets. Figure 1 , including a conveying frame 1 and a supporting frame 2. The conveying frame 1 includes an inclined conveying platform 3. The conveying platform 3 includes a feeding side 4 and a discharging side 5. The conveying platform 3 is inclined downward from the feeding side 4 toward the discharging side 5. The conveying platform 3 is provided with a blanking hole 6. The diameter of the blanking hole 6 is larger than the diameter of the rotor sheet and smaller than the diameter of the stator sheet. The blanking hole 6 is for the rotor sheet to pass through.

[0027] The support frame 2 is provided with a drive member 7, and the conveyor platform 3 is provided with a limit plate 8. The limit plate 8 is located between the blanking hole 6 and the feed side 4. The limit plate 8 is tilted toward the discharge side 5 and toward the conveyor platform 3. The side of the limit plate 8 closest to the conveyor platform 3 forms a screening gap 9 with the conveyor platform 3, which allows the stator or rotor segments to pass through the screening gap 9. The drive member 7 is connected to the limit plate 8 and is used to drive the limit plate 8 to move toward or away from the conveyor platform 3, thereby facilitating the adjustment of the size of the screening gap 9. In actual use, the drive member 7 can be a pneumatic cylinder, or alternatively, an oil cylinder.

[0028] Limiting plate 8 is provided with a limiting member 10, which is used to restrict the movement of the stator segments toward the discharge side 5. When the driving member 7 drives the limiting plate 8 toward the conveyor platform 3, the screening gap 9 allows a single stator segment or rotor segment to pass through. When the driving member 7 drives the limiting plate 8 away from the conveyor platform 3, the limiting member 10 restricts the movement of the stator segments toward the discharge side 5.

[0029] In the present application, the limiting member 10 is located between the blanking hole 6 and the feed side 4. The limiting member 10 includes a first limiting screw 11, a first limiting circular plate 12, a second limiting screw 13, and a second limiting circular plate 14. The first limiting screw 11 and the second limiting screw 13 are both rotatably connected to the conveying platform 3. The first limiting screw 11 and the second limiting screw 13 are both provided with threads, and the thread direction of the first limiting screw 11 is opposite to the thread direction of the second limiting screw 13. The first limiting screw 11 and the second limiting screw 13 are both threadedly connected to the limiting plate 8.

[0030] The first limiting circular plate 12 is coaxially mounted on the first limiting screw 11. The rotation of the first limiting screw 11 drives the first limiting circular plate 12 to rotate. The first limiting circular plate 12 is provided with a first limiting bar 15 located on the peripheral wall of the first limiting circular plate 12 and configured to abut against the stator segments. In actual use, a clearance groove is provided on the end of the limiting plate 8 proximate to the conveyor platform 3 to reduce interference with the first limiting circular plate 12 during movement of the limiting plate 8.

[0031] The second limiting circular plate 14 is coaxially arranged on the second limiting screw 13. The rotation of the second limiting screw 13 drives the second limiting circular plate 14 to rotate. The second limiting circular plate 14 is provided with a second limiting bar 16. The second limiting bar 16 is located on the peripheral wall of the second limiting circular plate 14 and is used to resist the stator plate.

[0032] In actual use, when the driving member 7 drives the limit plate 8 to move toward the conveying platform 3, the size of the screening gap 9 is reduced. At this time, the screening gap 9 is only for a single stator sheet or rotor sheet to pass through, and the first limit screw 11 and the second limit screw 13 are rotated so that the first limit bar 15 and the second limit bar 16 do not play a role in limiting the stator sheet.

[0033] When the driving member 7 drives the rod limiting plate 8 to move in a direction away from the conveying platform 3 , the first limiting strip 15 and the second limiting strip 16 have a limiting effect on the stator sheet, facilitating the passage of the rotor sheet.

[0034] The implementation principle of a stator plate and rotor plate screening and separation device in an embodiment of the present application is as follows: in actual use, when the driving member 7 drives the limit plate 8 to move toward the direction close to the conveying platform 3, the screening gap 9 allows a single stator plate or rotor plate to pass through. At this time, when the rotor plate is located below the stator plate, the rotor plate can pass through the screening gap 9, while the stator plate is blocked and screened.

[0035] If the rotor sheet is located above the stator sheet at this time, the stator sheet passes through the screening gap 9 , the rotor sheet is screened and then moves toward the blanking hole 6 .

[0036] When the driving member 7 drives the limiting plate 8 to move away from the conveying platform 3, the limiting member 10 limits the movement of the stator sheet toward the discharge side 5. At this time, the limiting member 10 blocks the movement of the stator sheet. However, due to the increase in the screening gap 9, the rotor sheet can slide and pass through the screening gap 9 regardless of whether it is located above or below the stator sheet. However, due to the limiting effect of the first limiting bar 15 and the second limiting bar 16, the stator sheet does not move further at this time, thereby achieving separation of the stator sheet and the rotor sheet.

[0037] Secondly, the reciprocating movement of the limiting plate 8 is driven by the driving member 7, thereby reducing the possibility of the stacked stator sheets and rotor sheets being stuck in the screening gap 9 during the screening process.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
