Description

Technical Field

[0001] The utility model relates to the technical field of shielding cover processing and detection equipment, in particular to a shielding cover visual detection device. Background Art

[0002] Shielding covers are devices used for electromagnetic shielding and are widely used in electronics, electrical appliances, and medical applications. Their shielding effectiveness is affected not only by the material used but also by the precision of their assembly. Porosity and gaps in the connections can reduce their effectiveness. During the production process, shielding covers are typically assembled and connected through welding. Porosity, gaps, and undercuts at the welds can degrade the cover's performance.

[0003] Currently, in the welding process of shielding covers, manual visual inspection of welding points is required to ensure the welding quality of the shielding covers to prevent the outflow of shielding cover products with pores or gaps. However, manual inspection is inefficient, and long-term inspection operations are prone to missed inspections and incorrect inspections of welding points.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a shielding cover visual inspection device to solve the above problems.
