The stator core is generally relatively heavy, so the above operations increase the labor intensity of workers. In addition, it is easy to miss or mis-transfer due to human error. In the prior art, a manipulator component can also be used to complete the above process, but due to the high cost of the manipulator, the production cost of the stator core will be increased.

[0022] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings.

[0023] As Figure 2 , Figure 6 shown, a stator core transfer device, the stator core 1 includes: an annular part 11, and the annular part 11 has a vertically penetrating middle hole 111. The stator core transfer device includes:

[0024] The first plate body 2, as Figure 1 , Figure 3 , Figure 5 , Figure 7 shown, the first plate body 2 specifically includes: a first body portion 21, and a first plate portion 22 and a second plate portion 23 extending from one end of the first body portion 21. There is a gap 24 between the first plate portion 22 and the second plate portion 23. The stator core 1 can be carried on the first plate portion 22 and the second plate portion 23 at the first position;

[0025] The second plate body 3, the second plate body 3 specifically includes: a second body portion 31, and a protrusion 32 on the second body portion 31;

[0026] The first driving component 4, connected to the second plate body 3, can drive the second plate body 3 to move horizontally back and forth. The first driving component 4 can drive the second plate body 3 to reach the second position. When the second plate body 3 is in the second position, the protrusion 32 is coaxially arranged with the stator core 1 located at the first position and the protrusion 32 is located below the gap 24;

[0027] The second driving component 5, connected to the second plate body 3, can drive the second plate body 3 to move upward from the second position to the third position, and make the protrusion 32 with an outer diameter adapted to the inner diameter of the middle hole 111 pass through the gap 24 and insert into the middle hole 111;

[0028] The first driving component 4 can also drive the second plate body 3 to move horizontally from the third position to the fourth position where the stator core 1 is separated from the first plate body 2 and is independently carried by the second plate body 3.

[0029] In practical applications, the first driving component 4, the second driving component 5, and the third driving component 6 can be cylinder driving components.

[0030] Through the above stator core transfer device with a relatively simple structure, the transfer of the stator core 1 from the first plate body 2 to the second plate body 3 can be realized.

[0031] The stator core transfer device further includes a third driving component 6, and the third driving component 6 can drive the stator core 1 carried on the first plate body 2 to move to the first position.

[0032] In the first embodiment of the present invention, as Figures 1 to 4 shown, the first plate portion 22, the second plate portion 23, and the gap 24 therebetween form a U-shaped structure with an opening facing the second plate body 3. The gap 24 of the U-shaped structure is larger than the width of the second body portion 31, and the outer diameter of the protrusion 32 is adapted to the inner diameter of the middle hole 111.

[0033] The working process of the stator core transfer device in the first embodiment is as follows:

[0034] Before the handover starts, the stator core 1 is carried on the first plate body part 22 and the second plate body part 23 at the first position. The second plate body 3 is horizontally moved to the second position under the drive of the first drive assembly 4. At the second position, the protrusion 32 is coaxially arranged with the stator core 1 located at the first position and the protrusion 32 is located below the gap 24. Thereafter, the second drive assembly 5 drives the second plate body 3 to move upward to the third position, and enables the protrusion 32 with an outer diameter adapted to the inner diameter of the middle hole 111 to pass through the gap 24 and insert into the middle hole 111. At this time, the bottom surface of the annular part 11 is flush with the upper surface of the second body part 31. Finally, the second plate body 3 returns under the drive of the first drive assembly 4, so that the stator core 1 is separated from the first plate body 2 and reaches the fourth position carried independently by the second plate body 3. The bearing surface of the stator core 1 is smoothly transitioned from the first plate body part 22 and the second plate body part 23 to the upper surface of the second body part 31. In this way, the stator core 1 is smoothly handed over from the first plate body 2 to the second plate body 3.

[0035] Embodiment 1 is applicable to the case where the width of the second plate body 3 is small.

[0036] Embodiment 2 of the present utility model is as Figures 5 to 7 shown. There is a step 33 adjacent to the protrusion 32 on the second body part 31. When the second plate body 3 is in the third position, the bottom surface of the annular part 11 contacts the upper surface of the step 33, the side wall of the step 33 is attached to the inner wall of the gap 24, and the lower bottom surface of the first plate body 2 contacts the upper bottom surface of the second body part 31.

[0037] The working process of the stator core handover device in Embodiment 2 is as follows:

[0038] Before the handover starts, the stator core 1 is carried on the first plate body part 22 and the second plate body part 23 at the first position. The second plate body 3 is horizontally moved to the second position under the drive of the first drive assembly 4. At the second position, the protrusion 32 is coaxially arranged with the stator core 1 located at the first position and the protrusion 32 is located below the gap 24. Thereafter, the second drive assembly 5 drives the second plate body 3 to move upward to the third position, and the protrusion 32 with an outer diameter adapted to the inner diameter of the middle hole 111 passes through the gap 24 and is inserted into the middle hole 111. At this time, the bottom surface of the annular part 11 contacts the upper surface of the step 33, the side wall of the step 33 is attached to the inner wall of the gap 24, the lower bottom surface of the first plate body 2 contacts the upper bottom surface of the second body part 31. Finally, the second plate body 3 returns under the drive of the first drive assembly 4, so that the stator core 1 is separated from the first plate body 2 and reaches the fourth position where it is independently carried by the second plate body 3. Because the bottom surface of the annular part 11 contacts the upper surface of the step 33, after the stator core 1 is separated from the first plate body 2, the bearing surface of the stator core 1 will smoothly transition from the upper surfaces of the first plate body part 22 and the second plate body part 23 to the upper surface of the step 33. And the side wall of the step 33 is attached to the inner wall of the gap 24, so that the surface area of the upper surface of the step 33 bearing the stator core 33 is as large as possible, so that the stator core 1 can be placed on the step 33 more smoothly. In addition, the lower bottom surface of the first plate body 2 contacts the upper bottom surface of the second body part 31. This not only shortens the upward movement stroke of the second drive assembly 5 driving the second plate body 3, saves energy and device layout space, improves the handover efficiency, but also can play a role in positioning the height of the step 33 to ensure that its upper surface is flush with the bottom surface of the annular part 111. In this way, the stator core 1 is smoothly handed over from the first plate body 2 to the second plate body 3.

[0039] Embodiment 2 is applicable to the case where the width of the second plate body 3 is relatively large.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
