Description

Technical Field

[0001] This utility model relates to the field of coating production line technology, specifically to a test sample fixing device for coating production line. Background Technology

[0002] Coating technology is an important means of corrosion protection, widely used in the automotive and home appliance industries. In automotive factories, coating generally includes three main processes: pretreatment, electrophoresis, and painting. Pretreatment is currently mainly divided into two types: phosphating and phosphate-free treatments. The primary purpose is to improve the corrosion resistance of the substrate and the adhesion between the substrate and the electrophoretic paint. Since the quality of the substrate's pretreatment directly affects the corrosion resistance of the car body, the pretreatment performance of a particular substrate must be evaluated before it can be used in the manufacture of car body parts.

[0003] However, during the initial certification phase, before the steel substrate is used in parts production, the only way to conduct coating suitability tests on the painting site is by using sample hanging. Electrophoretic coating requires different steps such as electrophoresis, washing, and baking. Compared to the assembled body-in-white after a series of processes on the production line, the sample has lower tolerance. This requires that the sample be clamped and hung securely during the testing process to prevent it from shaking and reducing the quality of cleaning and coating. Currently, laboratory samples are generally suspended by pierced wire, which is very easy to shake during the later washing or baking process, affecting the pretreatment quality of the sample itself and scratching the uncured paint film, seriously affecting the paint film quality of other parts of the body. Therefore, this utility model provides a test sample fixing device for the coating production line to solve the above problems. Utility Model Content
