Double-color vehicle body coating and spraying method and vehicle

Abstract

The invention discloses a double-color vehicle body coating and spraying method and a vehicle. The double-color vehicle body coating and spraying method comprises the following steps that first-time whole vehicle bottom color spraying is conducted on a vehicle body; the opening angle of the opening and closing piece is enlarged, so that the target piece is completely exposed, and spraying conditions are met; shielding the areas which do not need to be subjected to color register; a spraying motion track of the spraying robot is compiled; and the vehicle body is subjected to second-time color register spraying. Before the color register area is sprayed for the second time and before the color register area is shielded, the opening and closing piece forming shielding is opened through the special supporting assistive tool to the height about the same as that of the top cover, then the gap between the lower portion of the A column and the front cover is enlarged, the area, shielded by the front cover, below the A column is reduced to the minimum, and the space between the A column and the front cover is saved. The original shielded position is exposed through the change of the angle of the opening and closing piece, a surface capable of being sprayed is obtained, paint can be sprayed to the area, originally shielded by the front cover and not capable of being sprayed, below the A column, and the technical problem that paint is insufficient visually below the A column is directly solved.

Description

technical field [0001] The invention belongs to the technical field of car body painting, and in particular relates to a two-color car body painting spraying method and a vehicle, which effectively solves the problem that the color registration position cannot be sprayed without changing the product structure and without dismantling the door cover. Background technique [0002] With the development of personalized needs of passenger car customers, two-color or multi-color car bodies are gradually favored by the market. For painting technology, in the process of painting two-color or multi-color car bodies, is the boundary area of ​​each color clear? Cleanliness is the key quality point that needs to be discussed in the coating process. For some car bodies with color separation lines designed in special positions, the conventional color separation construction method cannot obtain the ideal paint film quality, so it is necessary to design a new two-color body spraying construc...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the situation in the prior art that due to the special structural design of individual models, after covering, there are still some color areas to be sprayed that cannot leak out, cannot be sprayed and the design still requires spraying paint, making it difficult to carry out two-color body spraying construction The present invention provides a two-color car body painting spraying method. On the basis of the general painting two-color car body spraying scheme, aiming at individual parts that are difficult to effectively spray two-color paint, innovatively spray on the second color registration area before spraying on the two-color car body. When the color registration area is covered, the front cover is opened to about the same height as the top cover, thereby expanding the gap between the A-pillar and the front cover, and minimizing the area under the A-pillar covered by the front cover. The area under the A-pillar that was originally blocked by the front cover and cannot be painted can be painted with paint, which directly solves the technical difficulty of the lack of paint under the A-pillar
