[0002] The paper tray is an important load-bearing component for placing electronic components. There are multiple parts bins on the paper tray. When the parts are placed in the parts bins, they are covered with a layer of plastic film. Since the surface of the paper tray has obvious granularity, the friction coefficient is relatively large. If the friction coefficient is too large, the plastic film of the parts and the paper tray will have relative displacement during long-term transportation, which will wear out the plastic film and directly contact the product, thus wearing out the paint on the outer surface of the product. Therefore, the surface of the paper tray needs to be sprayed.

The spraying device can quickly spray varnish on the part installation cavity of the paper tray, ensuring that the friction force is small enough when the paper tray is placed on the part, and will not cause wear on the outer surface of the part. The technical solution provides a device for varnish spraying, which is used to solve the problem of spraying a layer of varnish on the front of the paper tray to reduce its friction coefficient.
