Description

    This invention relates to a jig for electrodeposition coating.

    In the conventional cation (cation) electrodeposition coating process that produces a coating film, depending on the shape of the workpiece (processed product) and the processing method, a coating film failure may occur due to the generation of air pockets or the accumulation of processing liquid.

    In the air pocket, electrodeposition is applied in a state where air has accumulated in the work (product to be treated) soaked in the paint, or in a state where air has accumulated due to gas (hydrogen / oxygen) generated during electrolysis during processing. When this is performed, a coating film is not generated at the site, and the substrate is exposed.

    Further, in the liquid pool, there is a problem that, at the portion where the liquid pool is generated without flowing out of the paint, the coating film swells, is not cured properly, and the roughness (residue adherence) occurs in the baking and drying process.

For reference, patent documents related to electrodeposition coating that have been filed so far are introduced (see Patent Documents 1 and 2).
