Description

Technical Field

[0001] The utility model relates to a detection device, in particular to an electronic copper foil surface defect detection device. Background Art

[0002] During the production process of copper foil, due to the influence of factors such as production equipment, environmental conditions, raw and auxiliary materials, and production technology, defects such as pinholes, penetration points, pitting, indentations, notches, and wrinkles may appear on the copper foil, seriously affecting the product quality of the copper foil. When copper foil is used in the electronics industry, such as in the manufacture of printed circuit boards and the conductive layer of various electronic products, surface defects on the copper foil will directly affect the quality of the product. Therefore, it is necessary to detect the surface defects of the copper foil.

[0003] After searching, the patent with announcement number CN216847438U discloses an online detection device for the appearance quality of electrolytic copper foil. Through the mutual cooperation of two sets of upper and lower cameras and two sets of light sources, it can detect the appearance quality defects of the entire width of copper foil online in real time. No sample needs to be cut during the detection process, eliminating the subjective errors caused by manual visual inspection. After problems are found during the detection, targeted adjustments can be made in time, thereby improving the efficiency of the appearance quality detection of electrolytic copper foil and improving product quality.

[0004] Although the above solution can detect the appearance quality of copper foil, the light source and camera in the device are directly fixed on the bracket, resulting in the inability to adjust the distance between the camera and light source and the copper foil, and the illumination angle of the light source and the shooting angle of the camera cannot be adjusted. As a result, it is inconvenient to debug the installation position of the camera and light source during the installation of the device, which needs to be improved. Utility Model Content
