[0061] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0062] One 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. For example, the motor stator assembly is used as an example. The motor electronic assembly comprises a sequentially connected soldering terminal 201, a main body 202, a corolla terminal 203, a copper column 204, and a copper busbar 205. The side surface of the main body 202 is provided with a disc 2021. The disc 2021 is composed of multiple thin layers, and both the end surface and the cylindrical surface of the disc 2021 are sharp. The top surface of the main body 202 is annular, typically about 9 mm wide, and the bottom surface of the main body 202 is annular, typically about 14 mm wide. The parts packaging device 100 of 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 bottom receiving chamber 11 and a bottom accommodating chamber 12 that are interconnected. The bottom receiving chamber 11 is formed by at least partially radially expanding the top of the bottom accommodating chamber 12. The bottom surface 111 of the bottom receiving chamber 11 is connected to the wall 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 are no interfering parts between the side wall of the receiving chamber and the parts 200. The space on the chassis 1 where the parts 200 can be placed can accommodate 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 component 200 placed in the bottom plate 1 , and the top cover 2 has a top accommodating cavity 21 for accommodating the top of the component 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 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 package, the copper bar 205 is in a downward position, allowing the copper bar 205 to completely avoid and always be 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 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.

[0065] Since the chassis 1 and the top cover 2 are provided, 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, allowing the lower part of the part 200 to be placed in the bottom accommodating cavity 12. At the same time, an avoidance cavity 13 is provided, so that part of the part 200 faces the avoidance cavity 13, allowing the part 200 to be safely placed in the chassis 1, avoiding interference of the chassis 1 on 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.

[0066] Specifically, if Figure 11 As shown, the parts packaging device 100 can accommodate multiple parts 200, and there are multiple bottom receiving chambers 11 and bottom accommodating chambers 12, and correspondingly there are multiple top accommodating chambers 21. In other embodiments, there can also be only one bottom receiving chamber 11 and bottom accommodating chamber 12, and one top accommodating chamber 21.

[0067] Furthermore, if Figure 5 、 Figure 7 As shown, the parts packaging device 100 further includes a bottom wear-resistant plate 3 connected to the chassis 1. The bottom wear-resistant plate 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 wear of the chassis 1. Specifically, as shown in the figure, the bottom surface 111 of the bottom receiving cavity 11 is not annular and avoids the avoidance cavity 13. Therefore, it can support the parts 200 without interfering with other areas of the parts 200.

[0068] 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 .

[0069] Furthermore, if Figure 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.

[0070] In addition, if Figure 9 As shown, the top accommodating chamber 21 has a first chamber 211 and a second chamber 212, which are connected from the chamber opening to the chamber bottom. 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.

[0071] Furthermore, if Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 As shown, the top wear-resistant pad 4 has a side plate portion 41 that covers the side wall of the first cavity 211, and a plate bottom portion 42 connected to the side plate portion 41. The plate bottom portion 42 is arranged at the cavity bottom 2111 of the first cavity 211, and the side of the plate bottom portion 42 facing the first cavity 211 has an anti-rotation portion 43. When in use, the top cover 2 covers the part 200. The plate bottom portion 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. The anti-rotation portion 43 presses the top surface of the main body 202, making it difficult for the part 200 to rotate. This prevents the copper plate and copper column 204 from shifting to avoid the cavity 13 and prevents the part 200 from rubbing against the cavity walls, thereby ensuring the quality of the part 200. After the anti-rotation portion 43 presses the top surface of the main body 202, a gap is formed between the cavity sidewalls of the first cavity 211 and the peripheral sidewalls of the main body 202.

[0072] Alternatively, as Figure 10As shown, the anti-rotation portion 43 is formed by a plurality of protrusions arranged in an array. 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 can be other structures.

[0073] In addition, if Figure 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 set in the cover body 24. Figure 12 As shown, 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 the guide distance a, which is less than the radial distance b between the top wear-resistant pad 4 and the weld end 201. When the top cover 2 is covering the part 200, the top cover 2 is prevented from deflecting and pressing against the weld end 201 of the part 200.

[0074] 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 accommodating the parts 200 has a top stopper 22 that mates with the bottom stopper 14 of the chassis 1 in another parts packaging device 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 fit into the recessed groove, thereby securing the upper part of the parts packaging device 100 in place. In other embodiments, the bottom stopper 14 can be a boss, and the top stopper 22 can be a recessed groove.

[0075] 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. Figure 9 As shown, the top cover 2 has a cover surface extending flatly along the outer periphery of the opening of the top accommodating cavity 21, and has a top locking portion 23 on the cover surface. The bottom locking portion 15 cooperates with the top locking portion 23 to lock the bottom plate 1 and the top cover 2. The bottom locking portion 15 and the top locking portion 23 can be either a protrusion or a groove.

[0076] In addition, if Figure 3 As shown, to prevent the chassis 1 and the top cover 2 from being misaligned when they are fitted together, two chamfers 102 and two rounded corners 103 are provided at the four corner ends of the chassis 1, corresponding to the flange shape of the top cover 2, to achieve mechanical anti-misalignment.

[0077] Furthermore, if Figure 3 and Figure 8As shown, both the upper surface of the chassis 1 and the outer surface of the top cover 2 are provided with identification members 101. These identification members 101 may be L-shaped as shown in the figure. Two identification members 101 are provided on the chassis 1, diagonally opposite each other. When loading parts 200, their positions can be captured by a visual camera, enabling accurate positioning and alignment. The positions of the identification members 101 on the top cover 2 can be similarly positioned. In other embodiments, the shape and position of the identification members 101 may vary as needed.

[0078] In addition, the outer surface of at least part of the bottom of the top accommodating cavity 21 is smooth, which is convenient for the robot nozzle to grab the top cover 2 for loading. Similarly, the inner surface of at least part of the bottom of the bottom accommodating cavity 12 is also smooth.

[0079] Another embodiment of the present invention relates to a parts packaging device 300. Figure 15 and Figure 16 As shown, the parts packaging equipment 300 includes: at least one parts packaging device 100 in the above-mentioned embodiment, a base 301, a surrounding plate 302, a buffer plate 303 and a box cover 304. The parts packaging device 100 is arranged on the base 301, and a positioning member 3011 is arranged on the base 301. The bottom surface of the chassis 1 has a bottom limit member 14, and the bottom limit member 14 is arranged outside the bottom surface of the bottom accommodating cavity 12. The positioning member 3011 cooperates with the bottom limit member 14 for positioning. The surrounding plate 302 is arranged around the base 301 to form a placement space, and the parts packaging device 100 is placed in the placement space. The buffer plate 303 is arranged in the placement space and is pressed above the parts packaging device 100. The box cover 304 is used to seal the placement space.

[0080] Furthermore, if Figure 15 As shown, the buffer plate 303 includes a buffer layer 3031 and a rigid layer 3032 covering the buffer layer 3031. The parts packaging device 100 has multiple parts and is stacked. The buffer layer 3031 can be a foam board, and the rigid layer 3032 can be a steel plate.

[0081] Specifically, if Figure 15 and Figure 16As shown, during packaging, first place a chassis 1 on the bottom support 301, and the bottom limiter 14 of the chassis 1 cooperates, that is, the positioning member 3011 is inserted into the bottom limiter 14; then place the parts 200 on the chassis 1, cover the top cover 2, and complete the placement of the bottom part packaging device 100; stack the parts packaging device 100 on the bottom part packaging device 100, that is, take another chassis 1 and place it on the top cover 2 of the bottom part packaging device 100, and the top limit of the top cover 2 The positioning member 22 cooperates with the bottom limit member 14 of the chassis 1 to position the chassis 1, place the part 200 on the chassis 1, cover it with the top cover 2, and repeat the above-mentioned stacking operation of the parts packaging device 100. After the stacking is completed, the enclosure 302 is installed on the bottom support 301 to surround the outer periphery of the stacked parts packaging device 100, and the buffer plate 303 is placed in the placement space to cover the topmost part packaging device 100.
