Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for painting an automobile drip molding together with the vehicle body in the same color.

When painting a car, when painting the car body and drip molding in the same color, conventionally the car body and drip molding are painted the same color in separate processes, or they are hung on the same line as the car body using separate special tools. The commonly used method is to paint the same color.

However, with these conventional painting methods, there have been many cases in which color spots occur and the same color cannot be painted. Of course, when painting is done in a separate process, but even when painting is done by hanging it on the same line as the car body using a special tool, the car body and drip molding are not necessarily the same color, even if they are on the same line. Since the drip molding and the drip molding are moved completely unrelated to each other, if a new paint is applied while the line is in operation, color spots may occur between the new paint and the previous paint, or the hanging location of the drip molding relative to the line may be affected. - Color spots could often occur depending on the positional relationship.

The present invention has been devised in view of the above-mentioned drawbacks of the conventional painting method, and uses temporary fasteners to attach the drip molding to its attachment point, that is, the joint welding flange of the roof panel and body panel at a predetermined distance. The purpose is to effectively solve the color unevenness in conventional painting by temporarily fixing the drip molding in a held state, integrating the temporarily fixing drip molding with the vehicle body, and painting the vehicle body together.

Hereinafter, the present invention will be described in detail based on an illustrative embodiment. First, to explain the temporary fasteners used in the painting method according to the present invention, the temporary fasteners are shown in FIGS.
As shown in C, it is integrally molded from an elastic metal plate and has a substantially inverted L-shape as a whole, with a holding part 1a at the top and a mounting part 1b at the bottom.

The upper holding part 1a has an upper surface part 2 having a curved surface shape that blends in with the shape of the back surface of the drip molding, and has a locking protrusion 3 that protrudes outward over the entire width near the upper edge of one side, and An actuating piece 5 having a stopper piece 4 bent inwardly is provided at the center of the lower end continuously from the protrusion 3, and a space 6 is continuously cut out from the center of the upper surface part 2 on the other side, A retaining part 7 is formed in the space 6 and has a fixed length and is bent outwardly and upwardly, and includes at least the retaining bent part 7, the retaining protrusion 3, and the upper surface part 2. The shape of 1a is an elastic shape that can be locked on the back side of the drip molding described later. Specifically, such a holding part 1a
This structure securely holds the drip mold along the upper surface part 2 by locking the locking protrusion 3 and the locking bent piece 7 into engaging portions formed on both sides of the drip mold.

On the other hand, the attachment part 1b formed at the lower part of the temporary fastener
is a two-pronged elastic clamping claw 8 extending from the other side of the holding part 1a by a certain length, specifically, having a central part cut out and connected at the lower end; Another elastic clamping claw 10 facing into the central notch space 9 of the claw 8 is formed, and the lower ends of each clamping claw 8, 10 are respectively curved in opposite directions, and both clamping claws 8, 10 are inserted through the curved lower end. By elastically clamping the combined welded flange portion of the roof panel and the body panel, which will be described later with reference to 10, the temporary fastener itself is removably attached to the welded flange portion.

Next, we will explain the method of the present invention for painting both the drip molding and the vehicle body in the same color using the temporary fastener having the above structure. First, as shown in FIG. The locking protrusion 3 and the locking bent piece 7 are elastically locked with one touch to the engaging portions 11a and 11b integrally formed on both sides of the back surface of the drip molding 11, and the drip molding 11 is fixed to its length. Holding part 1a for multiple temporary fasteners depending on the size
Then, as shown in FIG. 3, the temporary fasteners themselves are attached to the combined welding flange portion 14 of the roof panel 12 and body panel 13 through the elastic clamping claws 8 and 10 of each attachment portion 1b, respectively. Temporary fastener holding part 1
The drip molding 11 held at a is temporarily fixed to the welding flange 14 at a close distance of 3 to 4 cm so as not to interfere with the painting of the vehicle body. After that, the car body and temporary drip molding 11
are painted together in a normal process.

Therefore, if both are painted on the same line using such a painting method, the drip molding 11 is integrated with the vehicle body due to the use of temporary fasteners, so even if new paint is applied, the drip molding 11 will move along the line as one unit. Therefore, there is no need to worry about color spots caused by applying new paint, as would be the case when both are painted independently, and it is possible to always paint the same color as the vehicle body.

After painting the same color, as shown in Fig. 4, the drip molding 11 can be temporarily fastened by pulling the drip molding 11 while pressing inward the actuating piece 5 hanging down on one side of the holding part 1a of the temporary fastening tool. It can be easily released, and if the temporary fastener itself is similarly pulled against the elastic clamping force of the clamping claws 8 and 10, the combined welding flange part 1
4 can be easily removed. The stopper piece 4 provided at the lower end of the actuating piece 5 serves to restrict the inner pressing of the actuating piece 5.

As described above, the present invention uses a temporary fastener that includes a holding part of the drip molding and a mounting part for the welding flange part, and once the drip molding is attached to the welding flange part at a close distance that does not interfere with painting the vehicle body. Since it is characterized by being temporarily fixed and painted integrally with the car body, it is possible to paint the drip molding together with the car body while keeping it as close as possible to the car body, which is different from conventional methods. The resulting problem of color spots can now be resolved. Moreover, being able to prevent the occurrence of color spots not only eliminates the need for corrective painting, but also increases the product value and greatly contributes to reducing manufacturing costs.

Furthermore, in the painting method according to the present invention, temporarily fixing the drip molding to the welding flange using a temporary fastener means that the drip molding is integrated with the vehicle body and flows in the same line regardless of whether before or after painting. Therefore, from this point of view as well, it can contribute to improving work efficiency, and there is no need to worry about where to place the drip molding each time.

Furthermore, since the temporary fasteners hold the vehicle body and the drip molding at a predetermined distance, it also provides the effect that the vehicle body itself and the entire drip molding are uniformly coated.
