[0092] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0093] One embodiment of the present invention relates to a parts packaging device 100. As shown in FIG1, 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 structures. 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.

[0094] As shown in Figures 2, 3, 6, 7, and 11, 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 connects 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 a side avoiding the bottom receiving cavity 11 to form a clearance cavity 13. The bottom surface 111 of the bottom receiving cavity 11 avoids the clearance cavity 13, meaning there are no interfering elements 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 presence of sharp or 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.

[0095] As shown in Figures 6, 7, and 12, 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. 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.

[0096] 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.

[0097] Specifically, as shown in Figure 11, 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.

[0098] Furthermore, as shown in Figures 5 and 7, the parts packaging device 100 also includes a bottom wear-resistant pad 3 connected to the chassis 1. The bottom wear-resistant pad 3 is at least partially embedded in the bottom receiving cavity 11 and covers the bottom surface 111 of the bottom receiving cavity 11 to prevent the chassis 1 from being worn. Specifically, as shown, the bottom surface 111 of the bottom receiving cavity 11 is not an annular structure and avoids the clearance cavity 13, so that while supporting the parts 200, it will not interfere with other areas of the parts 200.

[0099] Furthermore, as shown in Figures 5 and 7, the bottom wear-resistant pad 3 is an annular part that extends radially to cover the cavity wall of the clearance cavity 13.

[0100] Furthermore, as shown in Figure 9, the parts packaging device 100 also includes a top wear-resistant pad 4 connected to the top cover 2, the top wear-resistant pad 4 being at least partially embedded in the top receiving cavity 21 to prevent the top cover 2 from being worn.

[0101] Additionally, as shown in Figure 9, the top receiving cavity 21 has a first chamber 211 and a second chamber 212 connected from the cavity opening toward the cavity bottom, wherein the inner diameter of the first chamber 211 is larger than that of the second chamber 212. The bottom 2111 of the first chamber 211 extends horizontally and connects to the second chamber 212. The top wear-resistant pad 4 is at least partially disposed in the first chamber 211 and covers the bottom 2111 of the first chamber 211.

[0102] Further, as shown in Figures 10, 12, 13, and 14, the top wear-resistant pad 4 has a side plate portion 41 covering the side wall of the first chamber 211, and a plate bottom 42 connected to the side plate portion 41. The plate bottom 42 is located at the bottom 2111 of the first chamber 211, and the side of the plate bottom 42 facing the first chamber 211 has an anti-rotation portion 43. In use, the top cover 2 covers the part 200, the plate bottom 42 is used to press the top surface of the main body 202 of the motor stator assembly, the second chamber 212 is used to accommodate the welding end 201, and the anti-rotation portion 43 presses the top surface of the main body 202, making it difficult for the part 200 to rotate, preventing the copper plate and copper pillar 204 from deviating from the clearance cavity 13, and also preventing the part 200 from rubbing against the cavity walls, thus ensuring the quality of the part 200. After the anti-rotation part 43 presses against 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 peripheral side wall of the main body part 202.

[0103] Because of the top wear-resistant pad, and the anti-rotation part on the bottom of the top wear-resistant pad, the anti-rotation part holds the parts in place during installation, increasing the friction between the parts and preventing them from moving or being damaged. In addition, the top wear-resistant pad itself is wear-resistant, further preventing the parts from wearing down the top cover and from being damaged, thus improving the quality of parts transportation and storage, and also allowing the parts packaging device to be reused, reducing costs.

[0104] Optionally, as shown in FIG10, the anti-rotation portion 43 is formed by a plurality of protrusions arranged in a plurality. The anti-rotation portion 43 is multiple and is disposed along the circumferential direction of the bottom of the plate 42. In other embodiments, the anti-rotation portion 43 may have other structures.

[0105] Additionally, as shown in Figure 9, the top cover 2 has a cover body 24 and a cover flange 25 connected to the corner end of the cover body 24. The cover flange 25 extends toward the bottom of the top receiving cavity 21, which is disposed within the cover body 24. As shown in Figure 12, when the cover body 24 and the chassis 1 cooperate to cover the part 200, the distance between the cover flange 25 and the corner end of the chassis 1 is a guide distance a, which is less than the radial distance b between the top wear-resistant pad 4 and the welding end 201. During the process of the top cover 2 covering the part 200, it prevents the top cover 2 from shifting and pressing against the welding end 201 of the part 200.

[0106] Further, as shown in Figure 4, the bottom surface of the chassis 1 has a bottom limiting member 14, which is disposed outside the bottom surface of the bottom receiving cavity 12. As shown in Figure 8, the outer surface of the area where the top cover 2 receives the parts 200 has a top limiting member 22 that cooperates with and positions the bottom limiting member 14 of the chassis 1 in other parts packaging devices 100. In this embodiment, the bottom limiting member 14 can be a recessed groove, and the top limiting member 22 can be a boss. When the parts packaging devices 100 are stacked, the boss can be embedded in the recessed groove, thereby fixing and positioning the upper parts packaging devices 100. In other embodiments, the bottom limiting member 14 can also be a boss, and the top limiting member 22 can be a recessed groove.

[0107] Additionally, as shown in Figure 3, the chassis 1 has a flat surface extending along the outer periphery of the opening of the bottom receiving cavity 11, and a bottom locking part 15 is provided on the flat surface. As shown in Figure 9, the top cover 2 has a cover surface extending along the outer periphery of the opening of the top receiving cavity 21, and a top locking part 23 is provided on the cover surface. The bottom locking part 15 and the top locking part 23 cooperate to lock the chassis 1 and the top cover 2. The bottom locking part 15 and the top locking part 23 may be a protrusion and a groove, respectively.

[0108] In addition, as shown in Figure 3, to prevent misalignment when the chassis 1 and the top cover 2 are fitted together, two chamfers 102 and two rounded corners 103 are provided at the four corners of the chassis 1, which correspond to the shape of the flange of the top cover 2, thus achieving mechanical error prevention.

[0109] Furthermore, as shown in Figures 3 and 8, both the upper surface of the chassis 1 and the outer surface of the top cover 2 have marking elements 101. These marking elements 101 can be L-shaped, with two marking elements 101 on the chassis 1, positioned diagonally. When loading parts 200, their positions can be obtained via a vision camera, enabling accurate positioning and alignment. The marking elements 101 on the top cover 2 can be positioned similarly. In other embodiments, the shape and position of the marking elements 101 can be changed as needed.

[0110] In addition, the outer surface of the bottom of at least part of the top receiving cavity 21 is smooth, which facilitates the robotic arm's suction nozzle to grasp and load the top cover 2. Similarly, the inner surface of the bottom of at least part of the bottom receiving cavity 12 is also smooth.
