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

[0056] An embodiment of the present invention relates to a parts packaging device 100. Figure 1 As shown, the parts packaging device 100 is used to place parts 200. The parts 200 are taken as a motor stator assembly. The motor electronic assembly has a welding end 201, a main body 202, a corolla end 203, a copper column 204 and a copper bar 205 connected in sequence. The side surface of the main body 202 has a disc 2021. The disc 2021 is composed of many layers of very thin sheets. The end surface and the cylindrical surface of the disc 2021 are sharp structures. The top surface of the main body 202 is annular, and the ring width is generally about 9mm. The bottom surface of the main body 202 is annular, and the ring width is generally about 14mm. 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 , Fig.11As shown, the parts packaging device 100 includes: a bottom plate 1 and a top cover 2. The bottom plate 1 has a bottom receiving chamber 11 and a bottom accommodating chamber 12 which are interconnected. The bottom receiving chamber 11 is formed by radially expanding at least part of the top of the bottom accommodating chamber 12. The bottom surface 111 of the bottom receiving chamber 11 is connected to the wall surface of the bottom accommodating chamber 12 and extends radially toward the outside of the bottom accommodating chamber 12. The bottom surface 111 of the bottom receiving chamber 11 is used to receive the parts 200. The bottom accommodating chamber 12 radially expands on one side away from the bottom receiving chamber 11 to form an avoidance chamber 13. The bottom surface 111 of the bottom receiving chamber 11 avoids the avoidance chamber 13, that is, there is no interference between the side wall of the receiving chamber and the parts 200. The space on the bottom plate 1 where the parts 200 can be placed can receive the parts 200 while avoiding the sharp areas and easily deformed areas of the parts 200 as much as possible. The top cover 2 is used to cover the part 200 placed in the bottom plate 1 , and the top cover 2 has a top accommodating cavity 21 for accommodating the top of the part 200 .

[0058] like Figure 6 , Figure 7 , Fig.12 As shown, the bottom surface 111 of the bottom receiving cavity 11 is used to receive the main body 202, the bottom receiving cavity 12 is located in the area below the bottom receiving cavity 11 and is used to receive the corolla end 203, the avoidance cavity 13 is used to receive the copper column 204 and the copper bar 205 to protect the weak parts of the component 200, and the top receiving cavity 21 is used to receive the welding end 201. In the packaging, the copper bar 205 is in a downward state, allowing the copper bar 205 to completely avoid and always be in an upright state. After the bottom surface 111 of the bottom receiving cavity 11 receives the main body 202, the disc 2021 of the peripheral side wall of the main body 202 is an easily deformable area, and the edge of the disc 2021 also forms a sharp area. There may be a gap between the peripheral side wall of the main body 202 and the cavity side wall of the bottom receiving cavity 11 to prevent the disc 2021 from deforming.

[0059] Due to the provision of the chassis 1 and the top cover 2, the chassis 1 has a bottom receiving cavity 11 and a bottom accommodating cavity 12 which are interconnected. 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, so that the lower part of the part 200 is placed in the bottom accommodating cavity 12. At the same time, an avoidance cavity 13 is provided, so that a partial area of ​​the part 200 faces the avoidance cavity 13, so that the part 200 can be safely placed in the chassis 1, avoiding interference of the chassis 1 with the part 200, preventing the part 200 from wearing the chassis 1, and preventing the part 200 from being damaged, thereby improving the transportation and storage quality of the part 200, and making the part packaging device 100 recyclable to reduce costs.

[0060] Specifically, Fig.11 As shown, the parts packaging device 100 can hold multiple parts 200, and there are multiple bottom receiving chambers 11 and bottom accommodating chambers 12, and there are correspondingly multiple top accommodating chambers 21. In other embodiments, there may be only one bottom receiving chamber 11 and bottom accommodating chamber 12, and one top accommodating chamber 21.

[0061] Furthermore, if Figure 5 , Figure 7 As shown, the parts packaging device 100 further includes: a bottom wear-resistant pad 3 connected to the bottom plate 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 bottom plate 1 from being worn. Specifically, as shown in the figure, the bottom surface 111 of the bottom receiving cavity 11 is not an annular structure, avoiding the avoidance cavity 13, so that the parts 200 can be supported without interfering with other areas of the parts 200.

[0062] Furthermore, if Figure 5 , Figure 7 As shown, the bottom wear-resistant pad 3 is an annular member, radially extending to cover the cavity wall of the avoidance cavity 13 .

[0063] Furthermore, if Fig. 9 As shown, the parts packaging device 100 further includes: a top wear-resistant pad 4 connected to the top cover 2, and the top wear-resistant pad 4 is at least partially embedded in the top accommodating cavity 21 to prevent the top cover 2 from being worn.

[0064] In addition, if Fig. 9 As shown, the top accommodating chamber 21 has a first chamber 211 and a second chamber 212 connected from the chamber opening to the chamber bottom, and the inner diameter of the first chamber 211 is larger than that of the second chamber 212. The chamber 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 chamber bottom 2111 of the first chamber 211.

[0065] Furthermore, if Fig.10 , Fig.12 , Fig.13 , Fig.14 As shown, the top wear-resistant pad 4 has a side plate portion 41 covering the side wall of the first cavity 211, and a plate bottom 42 connected to the side plate portion 41. The plate bottom 42 is arranged at the cavity bottom 2111 of the first cavity 211, and the plate bottom 42 has an anti-rotation portion 43 on the side facing the first cavity 211. When 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 cavity 212 is used to accommodate the welding end 201, and the anti-rotation portion 43 presses the top surface of the main body 202, so that the part 200 is not easy to rotate, preventing the copper plate and the copper column 204 from deviating to avoid the cavity 13, and also preventing the part 200 from being close to the cavity walls and scratching, thereby ensuring the quality of the part 200. After the anti-rotation portion 43 presses the top surface of the main body 202, there is a gap between the cavity side wall of the first cavity 211 and the peripheral side wall of the main body 202.

[0066] Since the top wear-resistant pad is provided, and the anti-rotation part is provided at the bottom of the top wear-resistant pad, the anti-rotation part presses the parts when installing the parts, increases the friction between the parts, prevents the parts from moving, and prevents the parts from being damaged. In addition, the top wear-resistant pad itself is wear-resistant, which further prevents the parts from wearing the top cover, and also prevents the parts from being damaged, improves the quality of parts transportation and storage, and also makes the parts packaging device recyclable, reducing costs.

[0067] Alternatively, if Fig.10 As shown, the anti-rotation portion 43 is formed by arranging a plurality of protrusions. There are a plurality of anti-rotation portions 43, and they are arranged along the circumferential direction of the plate bottom 42. In other embodiments, the anti-rotation portion 43 may be other structures.

[0068] In addition, if Fig. 9 As shown, 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 accommodating cavity 21 away from the top accommodating cavity 21. The top accommodating cavity 21 is arranged in the cover body 24. Fig.12 As shown, when the cover body 24 cooperates with the chassis 1 to cover the part 200, the distance between the cover flange 25 and the corner end of the chassis 1 is the guide distance a, and the guide distance a is smaller than the radial distance b between the top wear-resistant pad 4 and the welding end 201. When the top cover 2 is covered on the part 200, the top cover 2 is prevented from deviating and pressing the welding end 201 of the part 200.

[0069] Furthermore, if Figure 4 As shown, the bottom surface of the chassis 1 has a bottom stopper 14, and the bottom stopper 14 is arranged outside the bottom surface of the bottom accommodating cavity 12. Figure 8 As shown, the outer surface of the top cover 2 in the area where the parts 200 are accommodated has a top stopper 22 that cooperates with the bottom stopper 14 of the chassis 1 in other parts packaging devices 100. In this embodiment, the bottom stopper 14 can be a recessed groove, and the top stopper 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 part packaging device 100. In other embodiments, the bottom stopper 14 can also be a boss, and the top stopper 22 can be a recessed groove.

[0070] In addition, if Figure 3 As shown, the bottom plate 1 has a plate surface extending flatly along the outer periphery of the opening of the bottom receiving cavity 11, and a bottom locking part 15 is provided on the plate surface. Fig. 9 As shown, the top cover 2 has a cover surface extending flat along the outer periphery of the opening of the top accommodating cavity 21, and the cover surface has a top locking part 23. The bottom locking part 15 cooperates with the top locking part 23 to lock the bottom plate 1 and the top cover 2. Among them, the bottom locking part 15 and the top locking part 23 can be one protrusion and the other a groove.

[0071] In addition, if Figure 3As shown, to prevent the chassis 1 and the top cover 2 from being misaligned when they are matched, two chamfers 102 and two rounded corners 103 are set at the four corners of the chassis 1, corresponding to the flange shape of the top cover 2, to achieve mechanical anti-misalignment.

[0072] Furthermore, if Figure 3 and Figure 8 As shown, the upper surface of the chassis 1 and the outer surface of the top cover 2 are provided with identification members 101, which can be "L" shaped as shown in the figure. The chassis 1 has two identification members 101, which can be located on the diagonal line when loading the parts 200, and can be accurately positioned and aligned by using a visual camera. The position of the identification member 101 on the top cover 2 can be set in the same way. In other embodiments, the shape and position of the identification member 101 can be changed according to needs.

[0073] In addition, at least part of the outer surface of the bottom of the top accommodating cavity 21 is a smooth surface, which is convenient for the robot nozzle to grab the top cover 2 for loading. Similarly, at least part of the inner surface of the bottom of the bottom accommodating cavity 12 is also a smooth surface.
