Description

Technical Field

[0002] Electrophoresis is a coating technology widely used in the fields of automobiles, home appliances, construction, aviation, etc. It has the advantages of beautiful appearance, corrosion resistance, and strong weather resistance. However, the problem of electrophoretic coating adhesion also needs to be paid attention to. Adhesion refers to the bonding force between the coating and the substrate, whether it can remain stable during use or processing. Low adhesion may cause problems such as coating peeling and scratches, seriously affecting product quality and performance.

[0003] The grid test is to conduct a grid test on the surface of a steel plate (specification 100mm*150mm) after electrophoresis. In the prior art, the sample is first placed on a table and held down by hand, and then a grid device is held down by another hand to grid the surface of the sample. Since the mutual friction between the table and the sample surface is small, one hand cannot completely hold down the sample during the grid process, resulting in uneven force and depth during the grid process. The standardization of the grid depth cannot be guaranteed, and the rework rate of drawing straight lines cannot be guaranteed. Therefore, other personnel are required to assist in the completion. Since the grid device is relatively sharp, there are also safety hazards when multiple people complete this work at the same time. Utility Model Content
