Description

Technical Field

[0001] The utility model relates to the technical field of film corrosion resistance inspection, in particular to a scribing device used for paint film corrosion resistance inspection. Background Art

[0002] Automobile painting is one of the four major automobile manufacturing processes. Through pre-treatment, electrophoresis and painting processes, a paint film is applied to the surface of the car body, which can provide protection and decoration for the car body. Electrophoretic paint film is a solid coating film that is plated on the metal surface by electrophoretic paint through "electroplating". Electrophoretic paint film is the most comprehensive and complete coating for metal workpieces in the current coating industry, with the best adhesion, the most uniform thickness and the most uniform appearance. Traditional spraying is very difficult to coat the inner cavity and the gap, and it is also prone to sagging problems. It is also difficult to paint multiple pieces at the same time. For electrophoretic coating, these can be easily achieved. It is a very high-quality and efficient coating. Especially the odor problem. It is difficult to avoid the "paint smell" in traditional painting, while the electrophoretic paint film is an odorless coating, which is particularly beneficial to environmental protection and people's health.

[0003] Corrosion resistance is one of the important indicators for evaluating the performance of electrophoretic paint films. When evaluating corrosion resistance, it is necessary to draw lines on the surface of the steel plate before conducting corrosion tests. Currently, there is no marking device for testing the corrosion resistance of paint films. Inspectors can only hold down the ruler with their hands to determine the position during the marking process. During the marking process, the hand is easy to loosen. Once the position of the hand moves, the position of the ruler changes, which leads to inaccurate marking. Moreover, the depth of the marking by different people is inconsistent. During the marking process, the depth of the marking cannot be guaranteed to be consistent, which affects the test results. Utility Model Content
