Description

Technical Field

[0001] The utility model relates to the technical field of sample hanging pieces, in particular to a sample hanging piece device for a painting production line. Background Technique

[0002] Painting technology is an important anti-corrosion means and is widely used in the automotive and home appliance industries. In an automobile factory, painting generally includes three main processes: pretreatment, electrocoating, and spraying. Among them, the current pretreatment is mainly divided into two methods: phosphating and phosphorus-free. The main purpose is to improve the anti-corrosion ability of the substrate and the bonding force between the substrate and the electrocoating paint. Since the quality of the substrate pretreatment directly affects the corrosion resistance of the body, when a certain substrate is applied to the body, it is necessary to evaluate its pretreatment performance, and only when the performance meets the requirements can it be used in the manufacture of body parts.

[0003] However, in the early certification stage, when the steel plate substrate has not been used for part production, only the method of hanging sample pieces can be used for the painting applicability experiment at the painting site. Electrocoating requires different steps such as electrocoating, water washing, and baking. Compared with the assembled white body, the sample pieces have a lower bearing capacity after a series of treatments on the production line. This requires that the sample pieces be clamped and hung firmly during the sampling process to prevent the sample pieces from shaking and reducing the cleaning and painting quality. Currently, in laboratory sampling, the method of hanging through a wire hole is generally used, which is extremely easy to shake during the subsequent water washing or baking process, affecting the pretreatment quality of the sample pieces themselves and scratching the uncured paint film, seriously affecting the paint film quality of other parts of the body. Therefore, the present utility model provides a sample hanging piece device for a painting production line to solve the above problems. Content of the Utility Model
