[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] There are currently two common construction methods for iron bumpers of automobiles and buses: the first is to separate the iron pressed bumper from the body for electrophoresis and painting; the second is to electrophoretically and paint the iron pressed bumper along with the sheet metal vehicle.

[0004] In the first construction method, during the painting process, the bumper and the body are usually constructed separately, and the intermediate coating and topcoat need to be baked and dried, which increases the electricity and gas costs for baking and drying the paint film. There are also differences in the spraying pressure, paint film thickness and other factors, which lead to color differences between the bumper topcoat and the body topcoat. Moreover, the increase in transportation and storage links will also increase the transportation workload, as well as the problem of scratch repair paint, further increasing the repair workload and cost.

[0005] In comparison, the second construction method is more efficient and less costly, but in the prior art, this method often results in uneven defects between the bumper and the outer surface of the vehicle body at the edges, which requires scraping and grinding putty to compensate. This is prone to defects such as scraping of the putty edge, and at the same time, putty residues are easily left in the joints and are difficult to clean, affecting the quality of visual detail processing of the coating. In addition, the paint film in the joints is thin, which is prone to rust problems, and the finishing efficiency and quality of the delivery process are difficult to guarantee.

[0006] Therefore, based on the existing technology adopting the second construction method, how to solve the defects of putty edges and scraping caused by the small gap between the bumper and the car body, putty residues in the joints that are difficult to clean, false paint in the frame edge and rust caused by improper paint spraying has become a key issue in improving the quality and efficiency of painting.
