Abstract

PURPOSE:To prevent defect of coating from occurring on electrostatic coating of a fuel lid. CONSTITUTION:Under a condition where a fuel lid 5 is mounted on a coating tool 11, the shortest distances from the inner peripheral parts of a frame 10 to the outer shape of the fuel lid 5 become approximately the same intervals. Namely, the fuel lid 5 is mounted on the coating tool 11 so as to make the lengths A, B, C and D approximately equal. When electrostatic coating is applied on the fuel lid 5, as the electric field of the surface of the fuel lid 5 becomes uniform, the surface of the fuel lid 5 is uniformly coated and it is possible to prevent defect of coating generated when the electrostatic coating of the fuel lid 5 is performed from occurring.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel lid coating jig suitable for electrostatic coating of a fuel lid of an automobile.

[0002]

2. Description of the Related Art Generally, in the body painting process of automobiles,
Automatic coating is performed by a robot. In this case, so-called electrostatic coating is performed in which the robot applies an electric charge to the paint to be sprayed and the body side is set to a potential of opposite polarity. By the way, the painting of the fuel lid is generally performed in a state where it is attached to the fuel supply port of the body,
In this way, the body of the portion corresponding to the hinge of the fuel lid cannot be sealed. Therefore, the present inventor has developed a jig for coating the fuel lid away from the body.

FIG. 3 is a front view showing the structure of this coating jig. In this figure, 2 is an insertion part to be inserted into a window groove of a door, and 3 is an L-shaped frame provided in the insertion part 2. , 4, 4 are convex portions provided on the frame 3, which are inserted into two holes provided in the hinge of the fuel lid 5 to fix the fuel lid 5. Reference numeral 6 denotes a support portion that supports the fuel lid 5 from the rear side, whereby the fuel lid 5 is fixed at a predetermined position even when the paint is sprayed from the front surface.

When the fuel lid 5 is attached to the above-mentioned jig and the painting is performed with the jig inserted and fixed in the window groove, the body and the fuel lid 5 can be painted in the same state, and the coating can be performed between them. The advantage that no unevenness occurs is obtained, and since the vicinity of the fuel supply port of the body is exposed, this portion can be easily sealed.
The jig is made of a conductive material,
The fuel lid 5 has the same potential as the body.

[0005]

By the way, when electrostatic coating is performed by the above-mentioned fuel lid coating jig, the coating material is concentrated on the outer peripheral portion of the fuel lid. It is considered that this is because the electric field at the outer edge of the fuel lid becomes extremely strong as compared with other portions, and at this time, there was a problem that paint was accumulated on the outer peripheral portion of the fuel lid, resulting in defective painting.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a coating tool for a fuel lid, which can prevent a coating failure caused when electrostatically coating the fuel lid.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a conductive frame surrounding the outer periphery of a fuel lid at a constant interval, and a lid provided on the frame for fixing the fuel lid. It is characterized in that it comprises a fixing means and a mounting means connected to the frame and attached to the body of the automobile so that the frame and the body are electrically connected to each other.

[0008]

Since the conductive frame surrounds the outer circumference of the fuel lid at a constant interval, when the fuel lid is fixed by the lid fixing means, the distance from the inner peripheral surface of the frame to the outer edge of the fuel lid is evenly spaced. become. In this state, when the frame is attached to the body of the automobile by the attachment means connected to the frame, the frame and the body are brought into an electrically conductive state, so that the coating that occurs when electrostatically painting the fuel lid is performed. It is possible to prevent defects.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the configuration of an embodiment of the present invention. In this figure, parts corresponding to those in FIG. 3 are assigned the same reference numerals and explanations thereof are omitted. 10 is a frame in which a cylindrical iron bar is formed by bending at four places,
The inner peripheral surface is larger than the outer shape of the fuel lid 5 and is formed in a shape substantially similar to the outer shape. On the left side of the inner peripheral surface of the frame 10, there are convex portions 4 and 4 extending in the horizontal direction.
Is formed, a supporting portion 6 extending upward is formed on the lower side of the inner peripheral surface of the frame 10, and a rectangular iron plate-shaped insertion portion 2 is connected to the lower side of the outer peripheral surface of the frame 10. The insertion portion 2 is inserted into a window groove of a door 13 attached to the automobile body 12 as shown in FIG.

In the above-mentioned structure, when the fuel lid 5 is attached to the coating jig 11, the distance from the inner peripheral surface of the frame 10 to the outer edge of the fuel lid 5 becomes equal. That is, A, B, C, D shown in FIG.
The fuel lid 5 is attached to the coating jig 11 so that the lengths of the fuel lid 5 are equal. Further, since the coating jig 11 is formed of a conductive member, the body and the fuel lid 5 have the same potential when the coating jig 11 is inserted and fixed in the window groove of the body.

Then, the distribution of the electric field in this case becomes stronger at the portion of the frame 10 located at the outermost periphery, and
It becomes constant in the fuel lid 5 inside 0. That is, in the case of the jig shown in FIG. 3, the electric field at the outer edge of the fuel lid 5 became strong, but in the present embodiment, since the conductive frame 10 was located outside the fuel lid 5, the electric field was strong. Is moved to the frame 10, and the electric field of the fuel lid 5 becomes flat. Moreover, since the distance between the inner peripheral surface of the frame 10 and the outer edge of the fuel lid 5 is constant, the electric field is uniform over the entire outer edge. Therefore, when the above-mentioned electrostatic coating is performed, the coating is not concentrated on the outer peripheral portion of the fuel lid 5 and is uniformly coated. In the above-described embodiment, the coating jig 11 is entirely made of a conductive member. However, for example, if the frame 10 and the body are connected by a cord or the like to make them conductive, the coating jig 11
May include a non-conductive member.

[0012]

As described above, according to the present invention, it is possible to prevent the coating failure caused when the fuel lid is electrostatically coated.
