[0002] Coating technology is an important anti-corrosion method, which is widely used in the automobile and home appliance industries. In automobile factories, coating generally includes three main processes: pre-treatment, electrophoresis and painting. Among them, pre-treatment is currently divided into two main treatment methods: phosphating and phosphorus-free. The main purpose is to improve the anti-corrosion ability of the substrate and the bonding strength between the substrate and the electrophoretic paint. Since the quality of the substrate pre-treatment is directly related to the corrosion resistance of the vehicle body, when a certain substrate is applied to the vehicle body, its pre-treatment performance needs to be evaluated. Only when the performance meets the requirements can it be used in the manufacture of vehicle body parts.

[0003] However, in the early certification stage, when the steel plate substrate has not yet been used for parts production, the coating suitability test work at the coating site can only be carried out by hanging samples. Electrophoretic coating requires different steps such as electrophoresis, water washing, and baking. Different personnel have different techniques, and the hanging positions and hanging methods of samples are different. A method with high operability and wide applicability to various types of vehicles is urgently needed. Summary of the invention
