[0001] This utility model relates to an oil spraying device, specifically an automatic oil spraying device for spraying oil onto plastic parts. Background Technology
[0002] Plastic parts are various components or parts made of plastic and are widely used in the automotive, electronics, and toy manufacturing industries. The main material of plastic parts is plastic, which has advantages such as low weight-to-weight ratio, good moldability, corrosion resistance, wear resistance, and good electrical insulation.
[0003] When processing some plastic parts, it is necessary to coat their surfaces with oil. Currently, the spraying devices used for coating plastic parts can usually only move in one direction, which results in a small area that the spray gun can cover when spraying oil, and therefore a small range of plastic parts that can be applied.

The rotating motor 21 is driven to move the first plastic part directly below the spray gun 43. The hydraulic cylinder 32 is driven to move all the structures below it downwards, so that the oil outlet of the spray gun 43 is positioned at the oil-to-be-sprayed location on the first plastic part. The spray gun 43 then sprays oil onto the first plastic part. Depending on the different oil-to-be-sprayed locations on different plastic parts and the different areas to be covered, the first servo motor 35 and the second servo motor 38 can be driven to move the spray gun 43 below the mounting plate 34, expanding the coverage area of the spray gun 43 so that various plastic parts can be accurately and quickly sprayed with oil.
