Reasons Why Artificial Solar Lighting XELIOS Is Used as a Light (light source for inspection) for Checking Uneven Paint and Coating, and Buff Marks of Automobiles?

Why is artificial solar lighting XELIOS used as a light for checking uneven paint and coating, and swirl marks (light source for inspection)?

To inspect paint color, it is important to check it under lighting whose spectral characteristics are similar to sunlight

There are two paint inspections for automobiles: a body-only paint inspection before it is mounted on the platform, and a completion inspection just before the vehicle is completed and shipped.
Since repainting after a defect in the paint is found after completion requires considerable effort and time, paint errors need to be found by inspecting the car body only before it is assembled into the platform.
The inspection at this time includes not only checking the color of the paint, but also scratches, stains, and foreign objects.
Automobile and auto body manufacturers pay considerable attention to their painting line, for example, by painting in a dust-free environment.
Still, however, it is impossible to eliminate the possibility of painting over dust.
This is foreign matter contamination, and detecting such coating errors in advance is the top priority of the inspection line.
Of course, scratches may occur during the process, or dents may be created by something bumping into it, so repainting before assembly is an important inspection in the process.

To facilitate the detection of scratches, stains, and foreign matter contamination, illuminating the target with highly directional light is required

While it is important to check the paint under lighting whose spectral characteristics are similar to sunlight for inspection of paint color, illumination with high directional light is necessary to facilitate detection of scratches, stains, and foreign matter contamination.
In a light environment with many fluorescent lamps like in the picture, it is difficult to detect scratches and other defects since checking them under the diffused light.
In contrast, artificial solar lighting XELIOS illuminates the objects with the light not only have a spectral characteristics similar to natural sunlight, but also directional light, making it easy to detect scratches and other defects, according to workers on site.

Uneven polish and swirl marks will also fail in the shipping inspection

When it comes to the completion inspection, they inspect not only the color and scratches, but also carefully examine any uneven polish or scratches by polishing.
The light environment at this time is also important to view with highly directional light, which is why the artificial solar lighting XELIOS is used as the inspection light source.

The XG-500AF is often used for post-paint and completion inspections of vehicle bodies.
On the car inspection line, four XG-500AFs are used on one side and eight on both sides.
An example of XG-100A in use is the 30 units arranged in 5 x 6 rows at the top of the car body.
We recommend both of them, but 8 units of 500W each are less expensive than 30 units of 100W each, both in initial and running costs.

It is a matter of course that shipping inspections are perfect, but if products are shipped with low painting quality, the customer may have a suspicion that “the car from this manufacturer is prone to breakdowns.”
Since the quality of the paint is the part that customers can see, it could even affect the reputation of all other qualities.
That is how important it is to inspect the surface condition of an automobile.
