Description

Technical Field

[0001] The present application relates to the technical field of paint surface detection and sampling, and in particular to a surface sampling device for furniture products. Background Art

[0002] During the production, quality control, and restoration of wooden furniture, paint inspection is a crucial step. Typically, this involves obtaining paint samples for component analysis, thickness measurement, and durability testing.

[0003] The traditional paint surface sampling method is manual scraping, which is not only complicated and time-consuming, but also has low sampling efficiency and cannot meet the needs of large-scale rapid testing. At the same time, manual scraping of paint surfaces has problems such as uneven sampling depth, which can easily lead to uneven sample thickness, thereby affecting the accuracy of test results. It is also relatively easy to damage the wood substrate, especially when multiple layers of paint samples need to be taken, as it is very easy to scratch the underlying paint or wood.
