Problems solved by technology

Some flow marks are generated on the inner surface of the car body, and some flow marks are generated on the outer surface of the car body. The flow marks on the inner surface do not affect the appearance of the car body and do not need to be polished, but the flow marks on the outer surface affect the appearance of the car body and need to be polished. It is the flow marks where the left and right rear doors of the car body are close to the corners of the B-pillar and the residual liquid drips on the side skirts. It is difficult to polish and handle. After polishing, there are different degrees of bottom leakage. The electrophoretic coating is the main anti-corrosion coating of the car body. The side skirt area is the first area where the car body is anti-corrosion, so there is a serious risk of anti-corrosion after polishing and leaking the bottom, and it may even attract claims from customers

Embodiment 1

[0028] Such as figure 2 As shown, the drainage aid of this embodiment is used to prevent electrophoretic flow marks from being generated on the B-pillar threshold on the vehicle body, and it is operated according to the following steps during use:

[0029] 1. According to the distance between the upper and lower structures of the door hinge of different models, adjust the distance between the fixing clip 1 and the positioning block 10 by adjusting the third adjusting bolt 8, and adjust the fixing clip through the adjusting bolt according to the distance between the door hinge and the lower side skirt 1 Distance from the body side skirt

[0030] 2. After distinguishing the left and right accessories, hold the fixing clip 1 by hand, and first insert the drainage liquid receiving plate 9 into the gap between the lower end of the rear door of the vehicle body and the side skirt;

[0031] 3. Install the fixing clip 1 and the positioning block 10, insert the positioning block 10 i...

specific Embodiment approach

[0054] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0055] Such as figure 1 As shown, the present invention provides a drainage aid, comprising a fixing device, a drainage liquid receiving tray 9 and a boom; the fixing device is to be fixed on the vehicle body during use; The electrophoretic paint that flows out from the gap of the vehicle body in the process leads away from the vehicle body;

[0056] Specifically, as figure 1 As shown, the length of the suspender of the drainage aid of the present invention is adjustable, one end of the suspender is connected to the fixing device, and the other end is connected to the drainage liquid receiving t...

Abstract

The invention discloses an auxiliary drainage tool and a method for preventing electrophoresis flow marks from being generated on the surface of an automobile body. The auxiliary drainage tool comprises a fixing device, a drainage liquid collection plate and a hanging rod. The fixing device is used for being fixed to the automobile body in use. The drainage liquid collection plate is used for guiding electrophoretic paint flowing out of cracks of the automobile body in the roasting process to be away from the automobile body. The hanging rod is connected with the fixing device and the drainage liquid collection plate. According to the auxiliary drainage tool, electrophoretic liquid squeezed out of the cracks of a metal plate of the automobile body in the roasting process of the automobile body can be converged and guided to be away from the automobile body through the fluid mechanics principle, and thus the flow marks are prevented from being generated on the outer surface of the automobile body.

Description

technical field [0001] The invention belongs to the technical field of electrophoresis technology for automobile painting, in particular, the invention relates to a drainage aid and a method for preventing electrophoresis flow marks on the surface of a vehicle body. Background technique [0002] During the painting process of automobile body-in-white, there are gaps in the body wrapping or sheet-metal overlapping parts, and the water-based electrophoretic paint has strong wettability to the cleaned steel plate. When the gap is appropriate, the electrophoretic paint will Accumulated in the crevice, although it is cleaned after electrophoresis, the electrophoretic paint still cannot be brought out from the crevice. When the drying temperature rises sharply, the surface tension of the liquid is destroyed or even boiled, and the electrophoretic paint in the gap flows out to produce flow marks on the surface of the car body. [0003] At present, the flow marks generated on the s...
