Description

Technical Field

[0001] The utility model relates to the technical field of automatic guided vehicles, in particular to an AGV air charging device. Background Art

[0002] An automated guided vehicle (AGV) is an industrial vehicle that loads goods automatically or manually, drives automatically along a set route or tows a cargo trolley to a designated location, and then loads and unloads goods automatically or manually.

[0003] Existing AGV carts usually place items directly on the top, and dust and impurities in the external environment can easily adhere to the top of the AGV cart. For some items with high dust-proof requirements, such as silicon wafers, if they are placed directly, they are easily contaminated by dust, resulting in black spots and other undesirable phenomena on the surface of the silicon wafers, which not only affects the appearance quality of the silicon wafers, but is also likely to have an adverse effect on its performance. Although simply adding a carriage to the AGV cart can reduce the entry of dust when the door is closed, when the door is opened and objects are put in and out, some dust will still enter the interior through the opening. Therefore, it is necessary to develop an AGV air injection device. Utility Model Content
