Description

Technical Field

[0001] This utility model relates to the field of copper strip surface quality detection technology, specifically to a darkroom observation device for copper strip samples. Background Technology

[0002] In the production process of copper strip, the inspection of its surface quality is crucial. As a key raw material in many industries such as electronics, electrical engineering, and machinery manufacturing, even minor surface defects in copper strip can affect the performance and quality of the final product. Currently, traditional methods for inspecting the surface of copper strip mainly rely on manual visual inspection under ordinary lighting conditions. However, under ordinary lighting conditions, minute scratches, pitting, abrasions, and other defects on the surface of copper strip are difficult to clearly see. Moreover, because the surface of copper strip has a certain metallic luster, it is prone to reflection under strong light, interfering with the inspector's vision and leading to misjudgments and missed defects. Furthermore, the environment in the production workshop is complex, with constantly changing external light intensity and angle, making it difficult to provide stable and reliable observation conditions. For high-precision, high-requirement copper strip products, existing inspection methods are no longer sufficient to meet the increasingly stringent quality control demands. Utility Model Content
