The present invention relates to a UV lamp fixing jig adopted in a curing machine, and prior to processing with a primer including a UV (Ultra-Violet) curable paint, and subjected to UV irradiation, and then the plating, vacuum deposition, just before painting and during the process. In order to complete UV Curing that can be unfinished by irradiating UV and at the same time, it cures uncured UV curable paint and increases the adhesive strength when painting. For the curing machine having a structure that can freely adjust the irradiation area of the UV, depending on the size and position of the object by allowing the free transfer of up and down in the state provided with a plurality of UV lamps provided to undergo a surface curing process by It is related to UV lamp fixing jig.

One of the most commonly applied materials is a polymer (multi-body), which is commonly known as a synthetic resin material (for example, polycarbonate, polyethylene, polyethylene terephthalite, polyimide, polyacetal, etc.). It is well known that various shapes are formed by the bar, and the appearance, the surface, etc. depend on the mold, and there is a limit in using the state in which it is injected.

Therefore, in order to overcome these limitations, the plating process (wet), vacuum deposition method (dry, vacuum thermal deposition, sputtering, ion plating, etc.) and painting processes are used to remove foreign substances in the injection, and to further improve plating, vacuum deposition, In order to show characteristics such as painting, UV primer treatment using UV lamp should be performed.

For example, at least one selected from the group consisting of ABS resin and UV curable paint on the surface of the injection-molded synthetic resin product is applied to the surface of the synthetic resin product to form a primer layer, electroless plating or vacuum deposition, sputtering Dry plating is performed by ion plating, but when the residue of monomer and the polymerization are not completely completed, many problems are caused in the process such as vacuum exhaust and adhesion. Of course.

Therefore, the surface of the synthetic resin injection molding, such as a mobile phone case, has a limitation in the irradiation range that UV is irradiated toward the surface of the product during the operation to harden the coating film by ultraviolet energy in consideration of the stability of the material and the merchandise of the product. However, if the irradiation angle is not correct, there is a problem that the surface coating film is not completely cured.

In addition, the means for fixing the yuv is installed so that it can be irradiated using a single yuv means only at a certain angle, one direction, it is difficult to completely harden phenomenon occurs due to the shadow formed on the opposite side or the lower side of the product, It provides a significant problem in the process of the vacuum exhaust, the advice used, etc., and has a problem such as an increase in defective production in terms of quality.

Accordingly, the present invention has been made to solve the above problems,

As well as forward and backward and forward and backward transfer of the UV to be irradiated, and providing a conveying device that can be transported up and down, the motion is different for each UV irradiation unit in the state that is equipped with a plurality of UV, forming, It is an object of the present invention to achieve curing by uniform UV irradiation over the entire surface of the molded injection molding by irradiation with different irradiation angles of the UV irradiation on the surface side of the injection molding.
