Problems solved by technology

[0003] Now, in order to ensure the aesthetic effect of the car and reduce the cost of mold development and post-painting, "bumper and grille integrated molding and painting" is a new technology that is currently sought after, but the bumper and grille after integral injection molding The grid has the characteristics of large volume, complex structure, and small grid gap. There are several problems in the paint spraying process: (1) orange peel phenomenon occurs; (2) robot spraying trajectory space is limited

Embodiment Construction

[0033] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0034] Please refer to Figure 1 to Figure 7 , the present invention provides an automobile bumper and grille integrated spraying process, which includes the following steps: Step 1) product positioning: hang the integrally formed bumper and grille 1 on the flip mounting bracket 2, and make the bumper and the outer surface 1a of the grille facing outward; Step 2) Spray primer: the robot sprays a layer of primer on the bumper and grille 1 from the outside, wherein the primer contains conductive carbon powder to improve adhesion and make Improve the painting rate of the color paint to avoid the orange peel phenomenon; step 3) spray the color paint; step 4) spray the varnish: after the color paint is leveled, first, the robot sprays the first layer on the bumper and grille 1 from the outside For varnish, after the first layer of var...

Abstract

The invention relates to an integrated spraying process for a bumper and a grille of an automobile, which is characterized by comprising the following steps of: (1) positioning a product: hanging the bumper and the grille which are integrally formed on a turnover mounting bracket, and arranging the outer surfaces of the bumper and the grille outwards; (2) primer is sprayed, specifically, the robot sprays a layer of primer to the bumper and the grating from the outer side, and the primer contains conductive carbon powder; (3) colored paint is sprayed; and (4) varnish spraying: after the colored paint is leveled, firstly, the robot sprays a first layer of varnish to the bumper and the grating from the outer side together, after the first layer of varnish is leveled, the mounting bracket is adjusted and overturned, so that the inner surfaces of the bumper and the grating are arranged upwards, and then the robot sprays a second layer of varnish to the grating from the upper side. The robot spraying device facilitates robot spraying, and the phenomena of spraying missing, orange peel and the like are avoided.

Description

technical field [0001] The invention relates to the field of paint spraying of automobile exterior trim parts, in particular to a process for integral spraying of automobile bumpers and grilles. Background technique [0002] With the development of the automobile industry, people have higher and higher requirements for the appearance of cars. In the 20th century, the grille was usually only injection molded without painting. With the change of people's aesthetics, grille painting has become a development trend. Traditional automobile During the project development of parts, different parts are usually designed and molded separately and painted separately, such as car bumpers and grilles. [0003] Now, in order to ensure the aesthetic effect of the car and reduce the cost of mold development and post-painting, "bumper and grille integrated molding and painting" is a new technology that is currently sought after, but the bumper and grille after integral injection molding The ...
