[0055] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0056] One embodiment of the present invention 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.

[0057] like Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 11As shown, the part packaging device 100 comprises a base 1 and a cover 2. The base 1 has a bottom receiving cavity 11 and a bottom accommodating cavity 12, the bottom receiving cavity 11 is formed by the top of the bottom accommodating cavity 12 at least partially extending radially. The bottom surface 111 of the bottom receiving cavity 11 is connected with the wall surface of the bottom accommodating cavity 12 and extends radially towards the direction outside the bottom accommodating cavity 12, and the bottom surface 111 of the bottom receiving cavity 11 is used to receive the part 200. The bottom accommodating cavity 12 avoids the side of the bottom receiving cavity 11 to form an avoiding cavity 13, and the bottom surface 111 of the bottom receiving cavity 11 avoids the avoiding cavity 13, that is, there is no interference between the cavity side wall of the receiving cavity and the part 200. The space on the base 1 where the part 200 can be placed can receive the part 200 while avoiding the sharp area and the easily deformed area of the part 200 as much as possible. The cover 2 is used to cover the part 200 placed in the base 1, and the cover 2 has a top accommodating cavity 21 to accommodate the top of the part 200.

[0058] As shown in Figure 6 , Figure 7 , Figure 12 , the bottom surface 111 of the bottom receiving cavity 11 is used to receive the main body part 202, the area below the bottom receiving cavity 11 of the bottom accommodating cavity 12 is used to accommodate the crown end 203, the avoiding cavity 13 is used to accommodate the copper column 204 and the copper bar 205, and the top accommodating cavity 21 is used to accommodate the welding end 201. In the packaging, the copper bar 205 is in a downward state, so that the copper bar 205 is completely avoided and always in an upright state. After the bottom surface 111 of the bottom receiving cavity 11 receives the main body part 202, the disc 2021 on the circumferential side wall of the main body part 202 is an easily deformed area, and the edge of the disc 2021 also forms a sharp area. There can be a gap between the circumferential side wall of the main body part 202 and the cavity side wall of the bottom receiving cavity 11 to prevent the disc 2021 from deforming.

[0059] Because the base 1 and the cover 2 are provided, the base 1 has a bottom receiving cavity 11 and a bottom accommodating cavity 12, the bottom surface 111 of the bottom receiving cavity 11 can support the part 200 when the part 200 is placed in the base 1, the lower part of the part 200 is placed in the bottom accommodating cavity 12, and the avoiding cavity 13 is provided to allow the part 200 to be placed in the base 1 safely, avoiding the interference of the base 1 with the part 200, preventing the part 200 from wearing the base 1, and also preventing the part 200 from being damaged, improving the quality of part 200 transportation and storage, and making the part packaging device 100 reusable, reducing costs.

[0060] Specifically, as shown in Figure 11 , the part packaging device 100 can place multiple parts 200, the bottom receiving cavity 11 and the bottom accommodating cavity 12 have multiple, and the top accommodating cavity 21 also has multiple corresponding. In other embodiments, there can be only one bottom receiving cavity 11 and one bottom accommodating cavity 12, and one top accommodating cavity 21.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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 and is connected to 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.

[0065] 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. In use, the top cover 2 is placed above the part 200, the plate bottom part 42 is used to press the top surface of the main body part 202 of the motor stator assembly, the second chamber 212 is used to accommodate the soldered end 201, and the anti-rotation part 43 presses the top surface of the main body part 202, so that the part 200 is not easy to rotate, preventing the copper plate and copper column 204 from deviating from the avoiding cavity 13, and preventing the part 200 from being scratched by the cavity wall, ensuring the quality of the part 200. 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.

[0066] Due to the setting of the top wear-resistant pad plate, and the setting of the anti-rotation part at the bottom of the top wear-resistant pad plate, the anti-rotation part holds the part when the part is installed, increases the friction between the part and the anti-rotation part, prevents the part from moving, and prevents the part from being damaged. In addition, the top wear-resistant pad plate itself is wear-resistant, further preventing the part from wearing the top cover, preventing the part from being damaged, improving the quality of part transportation and storage, and making the part packaging device reusable, thereby reducing costs.

[0067] Optionally, as shown in Figure 10 The anti-rotation part 43 is formed by a plurality of protrusions. The anti-rotation part 43 has a plurality of protrusions and is arranged along the circumferential direction of the bottom part 42. In other embodiments, the anti-rotation part 43 can have other structures.

Among them, one of the bottom locking part 15 and the top locking part 23 can be a protrusion, and the other can be a recess.

[0071] In addition, as shown in Figure 3As shown, the four corner ends of the bottom plate 1 are provided with two chamfers 102 and two round corners 103, which correspond to the flange shape of the top cover 2, so as to prevent misalignment when the bottom plate 1 and the top cover 2 are matched.

[0072] Further, as shown in Figure 3 and Figure 8 , the upper surface of the bottom plate 1 and the outer surface of the top cover 2 are both provided with an identification member 101, which can be an "L" shape in the figure. The bottom plate 1 is provided with two identification members 101 on the diagonal lines, so that the position can be acquired by a visual camera when the parts 200 are loaded, and accurate positioning and alignment are achieved. The position of the identification member 101 on the top cover 2 can also be the same. In other embodiments, the shape and position of the identification member 101 can be changed according to requirements.
