[0002] Electric vehicle plastic parts are an important part of electric vehicles. They not only protect the internal structure of the vehicle, but also improve the appearance of the vehicle and the comfort of the driver.

[0003] At present, when producing plastic parts for electric vehicles, the plastic particles are melted and the plastic melt is injected into the plastic parts to complete the shaping. Then, in order to ensure the beauty of the plastic parts, a paint spraying device (consisting of a drive device, a paint spray gun and other components) is used to color them. After the painting is completed, in order to ensure the quality of the paint, it is also necessary to undergo a manual re-inspection. At this stage, if any areas are found to have been missed, the staff will manually spray paint to touch up the paint, thereby ensuring that each plastic part can show a perfect appearance after the painting is completed.

[0004] Although the existing paint spraying devices perform well in the paint spraying process of electric vehicle plastic parts, there are still problems in actual operation. For example, during the painting process, due to the different shapes of plastic parts, in order to ensure the quality of the paint spraying, the movement trajectory of the paint spray gun needs to be adjusted to adapt to plastic parts of different shapes.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] The following describes the plastic parts processing device for a four-wheel electric vehicle according to an embodiment of the present application in conjunction with the accompanying drawings.

[0028] The four-wheel electric vehicle plastic parts processing device provided in the embodiment of the present application can be used for painting plastic parts. It can avoid frequent adjustment of the moving trajectory of the painting device during the painting process. This not only reduces the labor burden of the staff, but also effectively improves the painting efficiency of plastic parts, while ensuring that the painting operation can be carried out continuously and stably.

[0029] like Figure 1-Figure 5 As shown, the plastic parts processing device for a four-wheel electric vehicle according to an embodiment of the present application may include a housing assembly 1, a driving mechanism 2, a supporting assembly 3, a paint spraying mechanism 4, a sprinkler pipe 5 and a linkage mechanism 6.

[0030] It should be noted that, in order to better view the process of spray painting the plastic parts, transparent materials such as glass that are not easily painted can be used to complete the production of the warehouse body assembly 1.

[0031] The driving mechanism 2 is arranged on the supporting assembly 3 , and the supporting assembly 3 is connected to the bin body assembly 1 .

[0032] It should be noted that the driving mechanism 2 is installed on the bin body assembly 1 under the action of the supporting assembly 3, and the driving mechanism 2 is used to complete the process of hanging, feeding and discharging the plastic parts.

[0033] The paint spraying mechanism 4 is disposed on the bin body assembly 1 , and the paint spraying mechanism 4 may include a driving source 41 , a rotating assembly 42 and a paint spraying assembly 43 .

[0034] It should be noted that the driving source 41 described in the above embodiment may be a rotary motor.

[0036] It should be noted that an external paint tube (not shown in the figure) can be connected to the paint spraying assembly 43 to complete the process of painting the plastic parts.

[0037] Specifically, driven by the driving source 41 , the rotating assembly 42 drives the paint spraying assembly 43 to rotate, and then the paint spraying assembly 43 rotates at a high speed to complete the painting of the plastic parts suspended on the driving mechanism 2 .
