Description

Jig for antirust film processing {JIG FOR COATING RUST PROOFING FILM ON WORKPIECE}

The present invention relates to a jig for anti-rust coating, and more particularly, to a jig for anti-rust coating for treating anti-rust coating on a plated object by mounting a plated object.

In all industries, such as automobiles, ships, civil engineering, and electronics, the treatment of rust prevention coatings to prevent rust of metallic materials is a very important technology. Corrosion of various mechanical components and components such as bolts, nuts, washers, pins, etc. is directly related to life and performance and causes accidents.

An example of a rust inhibitor for the rust-preventive coating of metal materials is a coating fluid for a zinc-aluminum complex film. The coating solution for zinc-aluminum composite coating is composed of zinc flake, aluminum flake, inorganic binder, etc. It is well known as GEOMET (product name: Metal Coatings International Inc., USA) have. Geomet is a chromium-free water-based chemical solution with excellent corrosion resistance and coating properties and is widely used in many fields because of its lack of hydrogen embrittlement.

On the other hand, the rust-preventive coating process is performed through various processes such as spinning and curing after dipping a metal material into a coating liquid. In order to carry out a large amount of rust-preventive coating of a metal material, a metal material is mounted on a jig or a rack that is manufactured to match the shape of a metal material, and is put into each process.

Such a rust-preventive film processing jig can be easily found in many patent documents such as Korean Patent Laid-Open Publication No. 10-2011-0133718, Korean Patent Laid-Open Publication No. 10-2012-0018463, Korean Patent No. 10-1149742 have. The jigs of these patent documents are constructed so as to stably hang the object to be coated in order to ensure the quality of the rust-preventive coating coated on the surface of the object to be painted.

However, in the above-described conventional rust-preventing jig, liquid pooling occurs at a portion where the plated object and the jig come into contact with each other, thereby degrading the quality of the rust-preventing film and causing plating defects. In particular, when liquid pooling occurs in the hole of the to-be-plated object, the liquid pooling in the hole is very difficult to eliminate by spuning.

In addition, since the plated objects are arranged to be mounted on a single vertical plane, the number of the plated objects to be mounted is small, which leads to a low productivity. Since the jig should be mounted on a hook such as a trolley or a hoist, the plated object must be mounted thereon, resulting in troublesome mounting of the plated object and deterioration of workability.

The present invention is intended to solve various problems of the conventional anti-rust coating film processing jig. It is an object of the present invention to provide a jig for rust preventive coating that can improve the quality of the rust preventive coating because the portion to be contacted with the plated material and the jig is minimized.
