[0061] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0062] One embodiment of this utility model relates to a parts packaging device 100. For example... Figure 1 As shown, the parts packaging device 100 is used to place parts 200, taking a motor stator assembly as an example. The motor electronic assembly has a welded end 201, a main body 202, a crown end 203, a copper column 204, and a copper busbar 205 connected in sequence. The side peripheral surface of the main body 202 has a disc 2021, which is composed of many layers of very thin sheets. The end face and cylindrical surface of the disc 2021 are both sharp. The top surface of the main body 202 is annular, with a ring width of about 9 mm, and the bottom surface of the main body 202 is annular, with a ring width of about 14 mm. The parts packaging device 100 in this embodiment can also be used for other parts 200.

[0063] like Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 11As shown, the parts packaging device 100 includes a chassis 1 and a top cover 2. The chassis 1 has a through-hole bottom receiving cavity 11 and a bottom receiving cavity 12. The bottom receiving cavity 11 is formed by at least a portion of the top of the bottom receiving cavity 12 extending radially. The bottom surface 111 of the bottom receiving cavity 11 is connected to the wall of the bottom receiving cavity 12 and extends radially outward from the bottom receiving cavity 12. The bottom surface 111 of the bottom receiving cavity 11 is used to receive parts 200. The bottom receiving cavity 12 extends radially to form a relief cavity 13, avoiding the bottom receiving cavity 11. The bottom surface 111 of the bottom receiving cavity 11 avoids the relief cavity 13, meaning there are no interfering parts between the cavity sidewall of the receiving cavity and the parts 200. This design allows the space on the chassis 1 where parts 200 can be placed to receive parts 200 while minimizing the sharp and easily deformable areas of the parts 200. The top cover 2 is used to cover the part 200 placed in the chassis 1, and the top cover 2 has a top receiving cavity 21 for receiving the top of the part 200.

[0064] like Figure 6 , Figure 7 , Figure 12 As shown, the bottom surface 111 of the bottom receiving cavity 11 is used to receive the main body 202, the area of ​​the bottom receiving cavity 12 located below the bottom receiving cavity 11 is used to receive the crown end 203, the clearance cavity 13 is used to receive the copper pillar 204 and the copper busbar 205, protecting the weak parts of the part 200, and the top receiving cavity 21 is used to receive the welded end 201. In the packaging, the copper busbar 205 is in a downward position, allowing the copper busbar 205 to completely avoid the clearance and always remain in an upright position. After the bottom surface 111 of the bottom receiving cavity 11 receives the main body 202, the disc 2021 on the peripheral sidewall of the main body 202 is a deformable area, and the edge of the disc 2021 also forms a sharp area. There can be a gap between the peripheral sidewall of the main body 202 and the cavity sidewall of the bottom receiving cavity 11 to prevent the disc 2021 from deforming.

[0065] Because it is equipped with a chassis 1 and a top cover 2, the chassis 1 has a through bottom receiving cavity 11 and a bottom receiving cavity 12. When the part 200 is placed in the chassis 1, the bottom surface 111 of the bottom receiving cavity 11 can support the part 200, allowing the lower part of the part 200 to be placed in the bottom receiving cavity 12. At the same time, a relief cavity 13 is provided, so that part of the part 200 faces the relief cavity 13. This allows the part 200 to be safely placed in the chassis 1, avoiding interference from the chassis 1 with the part 200, preventing wear and tear on the chassis 1, and preventing damage to the part 200. This improves the quality of transportation and storage of the part 200, and also makes the part packaging device 100 reusable, reducing costs.

[0066] Specifically, such as Figure 11 As shown, the parts packaging device 100 can hold multiple parts 200, with multiple bottom receiving cavities 11 and 12, and correspondingly multiple top receiving cavities 21. In other embodiments, there may be only one bottom receiving cavity 11 and 12, and one top receiving cavity 21.

[0067] Further, as shown in Figure 5 , Figure 7 , the part packaging device 100 further comprises a bottom wear-resistant pad 3 connected to the bottom disc 1, the bottom wear-resistant pad 3 is at least partially embedded into the bottom receiving cavity 11 and covers the bottom surface 111 of the bottom receiving cavity 11, preventing the bottom disc 1 from being worn. Specifically, the bottom surface 111 of the bottom receiving cavity 11 is not annular structure as shown in the figure, avoiding the avoiding cavity 13, so that the part 200 can be supported without interfering with other areas of the part 200.

[0068] Further, as shown in Figure 5 , Figure 7 , the bottom wear-resistant pad 3 is an annular member extending radially to cover the cavity wall of the avoiding cavity 13.

[0069] Further, as shown in Figure 9 , the part packaging device 100 further comprises a top wear-resistant pad 4 connected to the top cover 2, the top wear-resistant pad 4 is at least partially embedded into the top receiving cavity 21, preventing the top cover 2 from being worn.

[0070] In addition, as shown in Figure 9 , the top receiving cavity 21 has a first chamber 211 and a second chamber 212 connected in communication from the cavity mouth of the receiving cavity to the cavity bottom, the inner diameter of the first chamber 211 is greater than that of the second chamber 212. The cavity bottom 2111 of the first chamber 211 extends horizontally to connect with the second chamber 212. The top wear-resistant pad 4 is at least partially disposed in the first chamber 211 and covers the cavity bottom 2111 of the first chamber 211.

[0071] Further, as shown in Figure 10 , Figure 12 , Figure 13 , Figure 14 , the top wear-resistant pad 4 has a side plate part 41 covering the side wall of the first chamber 211, and a plate bottom part 42 connected to the side plate part 41. The plate bottom part 42 is disposed on the cavity bottom 2111 of the first chamber 211, and the plate bottom part 42 has an anti-rotation part 43 on the side facing the first chamber 211.

After the anti-rotation part 43 presses the top surface of the main body part 202, there is a gap between the cavity side wall of the first chamber 211 and the circumferential side wall of the main body part 202.

[0072] Optionally, as shown in Figure 10As shown, the rotation preventing part 43 is formed by a plurality of protrusions arranged in a row. The rotation preventing part 43 has a plurality of parts and is arranged along the circumferential direction of the plate bottom part 42. In other embodiments, the rotation preventing part 43 can have other structures.
