方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for attaching a cushioning material to an automobile exterior component, which is applied to attaching a cushioning material along the edge of an automobile exterior component to prevent damage to a vehicle body panel. It is related to.

常である。Conventional technology In general, this type of cushioning material is made by extruding or injection molding a separate end rubber part into a continuous string shape, such as an approximately inverted U-shaped cross section, and then attaching the separate part to an automobile part using an adhesive or adhesive. It is usually attached by manually pasting along the edges.

虞れもある。 However, this manual work is extremely inefficient. In particular, when the periphery of an automobile exterior part has a complex shape that changes three-dimensionally, not only is it extremely time-consuming, but also the end rubber floats up and peels off at the curved parts of the periphery where it is difficult to adhere firmly enough. It becomes easier to do. In addition, stress is generated by tension when attaching the end rubber along the periphery, and the stress causes the end rubber to contract after the fact, which may result in a gap between the joints of the end rubber.

樹脂粘性液b1を硬化できるようにするとよい。 This synthetic resin viscous liquid b1 adheres along the edge of the automobile exterior part A while remaining in a viscous liquid state. It is possible to use a support jig C that exposes and clamps 1 in the groove S. This support jig C is composed of upper and lower receiving frames C 1 and C 2 into which the automobile exterior parts A are fitted and fitted with a distance W between them. In order to prevent damage to the surface of the automobile exterior component A, the receiving frames C 1 and C 2 are preferably formed so that the interval W is larger than the thickness of the component. to hold.
In addition, the groove S is finally formed with a synthetic resin viscous liquid B1 and has the same shape as the cross-sectional shape of the cushioning material B, and the peripheral part of the groove S sufficiently transmits ultraviolet rays. It is preferable that the synthetic resin viscous liquid b1 filled inside the groove S can be cured even by ultraviolet rays irradiated from the periphery of the groove S by forming it from a transparent material such as polycarbonate.

数本適宜位置に分散させて配置するとよい。 After the synthetic resin viscous liquid b 1 is injected and filled, the automobile exterior part A is sent into an ultraviolet irradiation furnace while being assembled to the support jig C as shown in FIG. 2C, and exposed to the ultraviolet rays of the synthetic resin viscous liquid b Curing is performed by irradiation. The feeding to this irradiation furnace can be carried out continuously by installing a continuous conveyor from the adhesion process of the synthetic resin viscous liquid B1 , and the ultraviolet irradiation can be carried out continuously using an 80w/cm ultraviolet lamp at a conveyor speed of 1~ It can be processed at a speed of about 10m/min. In this case, the amount of heat generated from the ultraviolet lamps should be adjusted so as not to cause thermal deformation of the automobile exterior part A, and several ultraviolet lamps may be dispersed and arranged at appropriate positions so as to avoid irradiation blind spots.

業環境の汚染も生じない。 In this way, when the synthetic resin viscous liquid b 1 is irradiated with ultraviolet rays, the synthetic resin viscous liquid b 1 hardens in a few seconds, and after that, when the automobile exterior part A is removed from the support jig C, the cushioning material B is attached along the edge. It can be obtained as a formed automobile exterior part A. Since the cushioning material B is a rubber-like material that is highly elastic and has a certain degree of viscosity due to the nature of the ultraviolet curable synthetic resin, it can sufficiently exert a cushioning effect on the vehicle body panel. Furthermore, since the ultraviolet curable synthetic resin does not contain an organic solvent, it does not undergo any volume change during curing and can maintain its shape, and does not contaminate the working environment with organic solvents.
