1 to 3 show a roof portion of an automobile having a panel covering structure according to an embodiment of the present invention. This roof part has a roof panel 1 installed on the upper surface of the ceiling part of the automobile, and a side rail outer panel 2 joined to the lower surface of the side part of the roof part. The joint part between the roof panel 1 and the side rail outer panel 2 In addition, it is a so-called Mohican roof type in which a recess 3 extending in the front-rear direction of the vehicle body is formed.

The recessed portion 3 is formed on the end portion thereof, that is, the front and rear end portions of the recessed surface which are inclined downward. A tape-shaped sealer 4 made of a synthetic resin material is installed in the recessed portion 3 except the end portion thereof, and a covering member 5 for covering the end portion of the tape-shaped sealer 4 is provided at the end portion of the recessed portion 3. is set up.

The tape-shaped sealer 4 is a thermosetting resin such as an epoxy-modified acrylic resin (vinyl ester resin),
Alternatively, a thermoplastic resin such as polyvinyl chloride resin having a relatively high flow temperature is formed into a sheet having appropriate flexibility, and is filled in the recess 3 as shown in FIG. It is stuck in.

The covering member 5 is made of a synthetic resin material such as polybutylene terephthalate (PBT) or a metal material having heat resistance to the extent that it does not deform when dried in a sealer drying furnace, which will be described later. 4 to 7
As shown in FIG. 3, the main body 5a has a main body 5a installed so as to cover the bottom surface of the recessed portion 3 and a projecting piece 5b provided so as to cover the upper end surface of the tape-shaped sealer 4. 5a
The adhesive layer 6 made of an epoxy-modified acrylic resin (vinyl ester resin) or a thermosetting resin material such as urea resin, melamine resin, or phenol resin provided on the lower surface of It is configured.

In order to form the covering structure of the panel, a vehicle body formed by a panel including the roof panel 1 and the side rail outer panel 2 is surface-treated with a surface treatment material such as zinc phosphate in a vehicle coating line. After applying, a primer is electrodeposited on this car body. Then, as shown in FIG. 8 and FIG.
The tape-shaped sealer 4 is installed from the one end to the other end by the sealer installation jig 7, and the end is cut by a pinch or the like, so that the end portion of the recess 3 is cut, as shown in FIG. The tape-shaped sealer 4 is installed on the portion excluding 3a.

The jig 7 for installing the sealer has a holding portion 8 for the tape-shaped sealer 4 wound in a roll shape, a feeding roller 9 for the tape-shaped sealer 4, and the recess 3 while pressing the tape-shaped sealer 4. And a sticking roller 10 that sticks to the bottom surface of the sticking roller. The pressing force of the tape sealer 4 is 1
It is preferably 4.7 N (1.5 kgf) or more. By setting the pressure of the tape-shaped sealer 4 in the above range,
The tape-shaped sealer 4 can be effectively attached to the bottom surface of the recess 3.

In order to facilitate the installation work of the tape-shaped sealer 4, the width of the tape-shaped sealer 4 is set to be smaller than the groove width of the recess 3 as shown in FIG. , The side end surface of the tape sealer 4 and the recess 3
It is desirable that a gap of about 1 mm be formed between the inner wall surface and the inner wall surface.

Thereafter, as shown in FIG. 12, a covering member 5 having an adhesive layer 6 formed by adhering a tape-shaped thermosetting resin material having appropriate adhesiveness to the lower surface,
The protrusions 5b of the covering member 5 cover the upper surface of the end of the tape-shaped sealer 4 by installing the front and rear ends 3a of the recess 3 respectively. Then, the installation range of the tape-shaped sealer 4 and the installation of the covering member 5 so that a space 11 having a space S of about 10 mm is formed between the tape-like sealer 4 and the main body 5a of the covering member 5. Set the position.

As shown in FIG. 13, the work of installing the tape-shaped sealer 4 and the covering member 5 on the vehicle body is performed in the sealer installation unit 13 after the primer coating work in the electrodeposition coating unit 12. Next, the tape-shaped sealer 4 is loaded by heating the vehicle body into the drying oven 14 and heating it.
After the adhesive layer 6 is dried and the adhesive layer 6 is cured, an intermediate coating material is applied to the vehicle body in the intermediate coating portion 15, and then an upper coating material is applied to the vehicle body in the top coating portion 16. The intermediate coating step may be omitted, and the top coating material may be directly applied after the tape-shaped sealer 4 and the like are dried.

The heating temperature of the drying oven 14 is higher than the softening point of the tape-shaped sealer 4, imparts appropriate fluidity to the tape-shaped sealer 4, and can cure the adhesive layer 6 of the covering member 5. It is set to temperature. For example, when the tape-shaped sealer 4 is made of an epoxy-modified acrylic resin, it is suitable to set the temperature within the range of 110 to 160 ° C. The heating time in the drying furnace 14 is preferably set to 10 minutes or longer. When the heating temperature is 160 ° C and the heating time is 3 hours,
When the heating temperature is 160 ° C. and the heating time is 30 minutes, the heating time is preferably 3 times or less.

By heating the tape-shaped sealer 4 installed in the recess 3 in the drying furnace 14, the sealer component having fluidity spreads in the recess 3 and is dried and hardened to be cured. It is fixed to 3. If a foaming agent is mixed in the tape-shaped sealer 4 and foamed when the tape-shaped sealer 4 is heat-treated, the tape-shaped sealer 4 is expanded to fill the recessed portion 3 inside. It can be effectively spread.

When the tape-shaped sealer 4 is in a fluid state, the sealer component which tends to flow down along the inclined surface formed in the terminal portion 3a of the recess 3 is formed between the coating member 5 and the sealer component. It is stored in the created space 11 (see the broken line in FIG. 12). As a result, the sealer component is prevented from flowing out of the covering member 5. Since the covering member 5 has heat resistance to the extent that it does not deform due to the heating temperature of the drying furnace 14 as described above, its shape is maintained.

Since the tape sealer 4 is installed in the recess 3 formed along the side edge of the roof panel 1 as described above, when it is heated and dried in the drying furnace 14, This can be fluidized and fixed in a state where it is spread in the recess 3. Therefore, without using a molding member such as a roof molding for concealing the recessed portion 3, the bottom surface of the recessed portion 3 can be covered with the tape-shaped sealer 4 with a simple structure to improve its appearance.

Further, by sealing the joint between the roof panel 1 and the side rail outer panel 2 provided in the recess 3 with the tape-like sealer 4, it is possible to ensure that moisture enters the passenger compartment through the joint. In addition, it is possible to effectively prevent the joint portion from being corroded under the influence of moisture.

Since the covering member 5 provided with the projecting piece 3b for covering the end portion of the tape-shaped sealer 4 is installed, the installation range of the tape-shaped sealer 4 is accurately set and the end portion is set. By covering the end portion of the tape-like sealer 4 with the covering member 5, the appearance can be improved without the need for the complicated work of proper treatment.

Further, in the roof panel 1 of an automobile in which the end portion 3a of the recess 3 is formed on the slanting surface which is inclined downward, when the tape sealer 4 is heated in the drying furnace 14 and fluidized. In addition, since the sealer component flowing down along the inclined surface can be blocked by the covering member 5, it is possible to effectively prevent the occurrence of a situation in which the sealer component is discharged to the outside and the appearance of the terminal portion 3a is deteriorated. Can be prevented.

Further, when the tape-shaped sealer 4 is formed of a thermoplastic resin material made of epoxy-modified acrylic resin or a thermoplastic resin such as polyvinyl chloride resin having a relatively high temperature in a fluidized state as described above, Even when the ambient temperature becomes high after curing, no deformation occurs and a stable use condition can be obtained.

When the covering member 5 is configured to be bonded to the bottom surface of the recess 3 by the adhesive layer 6 made of a thermosetting resin material, the tape sealer 4 is heated in the heating furnace 14. Then, the work of drying and the work of fixing the covering member 5 to the recess 3 by curing the adhesive layer 6 can be performed at the same time, so that the work process can be simplified.

Further, the tape sealer 4 and the covering member 5 are installed in the concave portion 3 of the vehicle body on which the primer has been electrodeposition coated in the electrodeposition coating section 12, and these are dried in the drying furnace 1.
4. When the intermediate coating material or the top coating material is applied to each panel constituting the vehicle body after heating in 4, the color of the tape-shaped sealer 4 and the covering member 5 is different from the vehicle body color. By applying an intermediate coating and a top coating thereon, these can be colored in the same color as the vehicle body.

Further, in the roof panel 1 in which the terminal portion 3a of the concave portion 3 is formed on the slanting surface which descends downward as described above, the end portion of the tape-shaped sealer 4 installed in the concave portion 3 and the concave portion 3 The installation range of the tape-shaped sealer 4 and the installation position of the covering member 5 are set so that the space 11 is formed between the main body portion 5a of the covering member 5 installed on the end portion 3a of the covering member 5. In the case of the construction, even if a dimensional error of the tape-shaped sealer 4 occurs and the installation range is somewhat widened, this dimensional error can be absorbed in the space 11. Further, since the space portion 11 can be used as a storage portion for the sealer component that flows down when the tape-shaped sealer 4 is dried, it is possible to reliably prevent the sealer component from flowing out.

14 and 1 in order to further improve the corrosion resistance of the joint portion between the roof panel 1 and the side rail outer panel 2 located at the end portion 3a of the recess 3.
As shown in FIG. 5, after the tape-shaped sealer 4 is installed in the concave portion 3, the sealing material 17 made of a thermoplastic resin material such as polyvinyl chloride or a thermosetting resin material such as polyurethane is led out from the nozzle 18, and You may make it install the said sealing material 17 along the joint part of the roof panel 1 and the side rail outer panel 2 located in the terminal part 3a.

Then, as shown in FIG. 16, by pressing the upper surface of the sealing material 17 with a spatula 19 or the like, the panel joint portion is surely covered with the sealing material 17, and the sealing material 17 and the tape-shaped sealer 4 is firmly attached to the concave portion 3 and then the concave portion 3
The covering member 5 may be installed on the terminal portion 3a. When the sealing material 17 that covers the joint between the roof panel 1 and the side rail outer panel 2 is installed in the terminal portion 3a of the recess 3 as described above, the joint is securely sealed and Corrosion resistance can be prevented more effectively.

In the above embodiment, as shown in FIG. 7, the groove width of the concave portion 3 and the width dimension of the covering member 5 are set equal to each other so that the covering member 5 is brought into close contact with the side wall surface of the concave portion 3. As shown in FIG. 17, the gap 2 for absorbing the dimensional error is provided between the side wall surface of the recess 3 and the covering member 5, as shown in FIG.
It may be configured such that 0 is formed. With such a configuration, even if there is some manufacturing error in the width dimension of the recess 3 or the covering member 5, the covering member 5
This can be easily installed in the recess 3 without causing any trouble in the installation work. The gap 20 is filled with the intermediate coating material or the top coating material when the intermediate coating material or the top coating material is applied, and is hidden.

Further, instead of the above-mentioned structure in which the adhesive layer 6 made of a thermosetting synthetic resin material is provided on the covering member 5, an adhesive layer made of a thermoplastic resin material or a fastener such as a clip is used to cover the covering member. 5 may be fixed to the terminal portion 3a of the recess 3. When the adhesive layer made of the thermoplastic resin material is used, when the tape sealer 4 is heated in the drying oven 14, the adhesive layer is softened and the installation position of the covering member 5 may change. In addition, when the above-mentioned locking tool is used, the fastening work is complicated and it is necessary to color the above-mentioned locking tool in the same color as the vehicle body beforehand. It is preferable that the covering member 5 is fixed by the adhesive layer 6 made of a synthetic resin material.

Further, the present invention is not limited to the covering structure and the covering method for covering the concave portion 3 formed along the side portion of the roof panel 1 with the tape-shaped sealer 4 and the covering member 5 and the like. Other than the above, the present invention can be applied to a recess of the vehicle body formed or a panel other than the vehicle body.
