Abstract

PURPOSE:To improve work efficiency while shortening a time necessary for heating an adhesive agent only, by temporarlly sticking a resin panel, in which an adhesive groove packed with the adhesive agent and a thin wall part are formed, to another resin panel, and curing the entire body of said adhesive agent during curing a coating film. CONSTITUTION:An adhesive groove 5 of 0.7-2.0mm. in depth having a protrudent thin wall part 6 is formed at a connecting part 4 formed as a unitary body with the right and left side parts and the lower end part of a synthetic resin door in- panel 2, and the interior of said groove 5 is packed with an adhesive agent 9 to which an induction heating accelerator is preadded so as to adjust the thickness of the thin wall part 6 to 0.1-0.5mm.. Thereafter, said panel 2 is overlapped with a synthetic resin door outer panel 3, and the built-up body is mounted on the receiving stand 11 of a high-frequency induction heater 10 while holding the panel 2 downside. The built-up body is then heated while clamping the thin wall part 6 and the panel 3 between upper and lower two electrodes 12 to cure the adhesive agent 9. Hence, the built-up body is temporally stuck. Thereafter, paint is applied onto the surface of the panel 3 and then heated to dry the paint and to cure the entire body of the adhesive agent with heat.

接着剤全体を加熱硬化させることにより両パネルを接着
する方法が採られている。Conventionally, when bonding synthetic resin panels together, adhesive is applied to one panel, the other panel is attached to the panel via adhesive, and the entire adhesive is heated using a heating device. A method has been adopted in which both panels are bonded together by heating and curing.

効率の向上を図ることを目的とするものである。The present invention has been made in view of this point, and the heating device is used only to temporarily attach the panels together, and when the paint film on the panels dries, the drying heat is used to heat and harden the entire adhesive together. By doing so, the heating device used can be small, reducing equipment costs, and the aim is to improve work efficiency by reducing the time required just to heat the adhesive. It is.

ある。For this purpose, the configuration of the present invention includes forming an adhesive groove in at least one of the first and second synthetic resin panels, and forming a thin wall portion in at least one of the panels corresponding to the adhesive groove, Prepare the above adhesive grooves filled with adhesive and put both panels together, heat and harden the adhesive corresponding to the thin part of the panel using a heating device, temporarily attach the above two panels, and then apply the coating on the above panel. By heating and curing the entire adhesive during film drying, both panels can be bonded together in a short heating time using a small heating device.

る。FIG. 1 and FIG. 3 show a first embodiment in which the method of the present invention is applied to the molding process of an automobile door panel 1, and the door panel 1 is a door inner panel made of synthetic resin such as unsaturated polyester resin containing glass fiber. It consists of a door outer panel 3 made of synthetic resin like 2, and the wall thickness of both panels 2 and 3 is set to about 2.5 to 3 mm for strength reasons. A series of joint parts 4 facing the left and right side ends and the lower end of the door inner panel 2 in contact with the door outer panel 3 are integrally formed by bending the door inner panel 2 toward the door outer panel 3 side. The left and right ends and lower end of the outer panel 3 are connected to the door inner panel 2.
It is bent inward so as to surround the tip of the joint 4.

The adhesive groove 5 has a truncated cone-shaped protrusion formed in the adhesive groove 5, which is thick or thinner than other parts ( (approximately 1+u+) are provided with a large number of thin-walled portions 6, 6, etc. The thin-walled portions 6,6,... are arranged at approximately equal intervals in the longitudinal direction of the bonding groove 5, and The protruding surfaces of each are set at substantially the same height as the upper surface of the joint portion 4 of the door inner panel 2. In FIG. 1, 7 is a door sash, and 8 is a door hinge metal fitting.

ウタパネル３とを互いに重ね合わせる。Therefore, when bonding the door inner panel 2 and the door outer panel 3 by polymerization, first, adhesive such as one-component urethane added with a dielectric heating accelerator such as barium titanate is applied to the bonding groove 5 of the door inner panel 2. The agent 9 is applied to the thin-walled portions 6, 6 .
After applying the coating to a thickness of about 0.1 to 0.5, apply the adhesive 9 to the joint 4 of the door inner panel 2 on the left and right ends of the door outer panel 3. Then, the door inner panel 2 and the door outer panel 3 are overlapped with each other by bringing their lower ends into contact with each other.

は絶縁材である。Thereafter, the ends of the overlapping door inner panel 2 and door outer panel 3 are placed on the pedestal 11 of the high-frequency dielectric heating device 10 with the door inner panel 2 facing downward, and the heating device 10 is heated. Each thin wall portion 6 of the door inner panel 2 and the door outer panel 3 portion corresponding to the thin wall portion 6 are sandwiched between the upper and lower two electrodes 12.12, and the adhesive 9 between them is approximately 1
By heating and curing at a temperature of 00 to 200°C,
Temporarily attach both panels 2 and 3 above. In addition, in Figure 2, 13
is an insulating material.

なわち仮付けの所要時間が極めて少なくて（数分）済み
、仮付は作業効率の向上を図ることかできる。At that time, since the thickness of each thin wall portion 6 of the door inner panel 2 is thinner than other portions of the door inner panel 2, the heating Dielectric heating of the adhesive 9 by the electrodes 12.12 of the device 10 can be effected effectively. Moreover, each of the thin portions 6 protrudes toward the door outer panel 3, and the thickness of the adhesive 9 corresponding to the thin portion 6 is thinner than the other portions of the adhesive groove 5. Coupled with the ability to effectively perform dielectric heating, the time required for heat curing of the adhesive 9, that is, the time required for tacking, is extremely short (several minutes), and tacking improves work efficiency. I can do it.

さらに、上記加熱装置１０は、薄肉部６，６゜・・に対

The heating device 10 itself can be downsized, and equipment costs can be reduced.

次いで、上記ドアアウタパネル３の表面に塗料等を塗布

体的に接着される。Next, after applying paint or the like to the surface of the door outer panel 3 to form a coating film, the temporarily attached door panel 1 (
When the door inner panel 2 and door outer panel 3) are carried into a paint film drying room or the like and the paint film is dried for a predetermined time (about 30 minutes) at a temperature of approx. The entire adhesive 9 of No. 5 is heated and cured, whereby the door inner panel 2 and the door outer panel 3 are bonded together.

An adhesive groove is formed in at least one of the synthetic resin panels, a thin wall portion is formed in at least one of the panels corresponding to the adhesive groove, the adhesive groove is filled with adhesive, and the two panels are joined together. The adhesive corresponding to the thin part of the panel is heated and cured using a heating device, and both upper panels are temporarily attached.Then, when the coating film on the above panel dries, the entire adhesive is heated and cured to bond both panels together. Therefore, the above-mentioned heating device can be small enough to be temporarily attached, which can reduce the equipment cost, and the temporary attachment can be done in a short time. Moreover, since it is not necessary to perform an operation solely for heating and curing the adhesive as a whole, the adhesive operation can be easily performed, and work efficiency can be greatly improved.
