Problems solved by technology
[0005] Commonly used electrophoretic film performance testing methods are: FAW steel pipe method, Ford box method and four box method. These electrophoretic film performance testing methods all have the following defects: 1. In the actual production process, especially in the volume of the coated object In larger cases (for example, the object to be coated is a car body), it is generally necessary to continuously move the object to be coated, so the flow state of the paint is also an important factor affecting the effect of the electrophoretic film, and the existing detection methods do not consider the paint. The influence of flow factors on the performance of the upper film; 2. When the existing detection method detects the data of the upper film, it needs to saw or disassemble the test sample, which makes the detection process complicated and cannot detect the performance of the upper film in real time

The invention relates to an electrophoretic on-film performance detection method and device. The method comprises the following steps: carrying out electrophoretic pre-treatment on a detection sampleplate; carrying out electrophoretic coating in a rotating state of the detection sample plate; and detecting the electrophoretic on-film performance data. The influence of the flowing state of the electrophoretic coating on the on-film performance can be detected by means of the electrophoretic on-film performance detection method and device.
Description
technical field [0001] The invention relates to the field of painting, in particular to a method and device for detecting the performance of an electrophoretic film. Background technique [0002] In recent years, the automobile industry has achieved considerable development, and the coating technology, one of the four major processes of automobile manufacturing, is also constantly innovating and progressing. Electrophoretic coating (may be referred to as swimming coating for short) is the first link of automobile body painting and the basis of the entire body painting. Its quality directly affects the anti-corrosion performance of the car body and the decorative effect of the paint film. [0003] In the process of electrophoretic coating, it is necessary to immerse the conductive coated object in a tank filled with electrophoretic paint as the anode (or cathode), and set the corresponding cathode (or anode) in the tank. , a uniform coating film will be deposited on the surf...
