Description

Technical Field

[0001] This utility model belongs to the field of PCB board processing technology, and in particular relates to a feeding device for a tin spraying machine. Background Technology

[0002] In the electronics manufacturing industry, tin-plating machines are used to apply tin plating to electronic components such as printed circuit boards (PCBs) to ensure good solderability. In PCB manufacturing, tin-plating machines are used to coat copper-clad laminates with a layer of tin-aluminum alloy. Tin is a low-melting-point metallic element, easy to process and shape, and it does not oxidize in air. Tin plating prevents rust and corrosion, as a protective tin dioxide film forms on the surface of the tin in the air, providing stability.

[0003] The existing patent document, with authorization announcement number CN217127509U and titled "A Material Unloading Assembly and a Soldering Machine Having the Assembly," describes a system where a fan support plate 702 is fixedly connected to one side of the top surface of an unloading platform 701. Multiple upper fans 703 arranged in a row are embedded in the top surface of the fan support plate 702, and lower fans 704 are correspondingly embedded in the top surface of the unloading platform 701 below the upper fans 703. Air is blown onto the PCB board 11 through the upper fans 703 and lower fans 704. Since both the upper fans 703 and lower fans 704 are located on the unloading platform 701, the PCB board 11 passes through the gap between the conical guide wheel 709 and the fan support plate 702. Because the gap between the conical guide wheel 709 and the fan support plate 702 is small, it easily leads to PCB board jamming, reducing the PCB board unloading efficiency. Utility Model Content
