Description

Technical Field

[0001] The utility model relates to the technical field of galvanized sheets, and specifically relates to a clamping tooling for detecting surface defects of galvanized sheets. Background Art

[0002] A galvanized sheet refers to a steel sheet with a layer of zinc plated on its surface. Hot-dip galvanized sheets are widely used in the production of automotive sheets, household appliance sheets, and building sheets. With the rapid development of China's economy, the demand for high-quality hot-dip galvanized sheets is increasing continuously. However, surface defects will seriously reduce the product quality. Therefore, it is quite important to accurately detect the surface defects of hot-dip galvanized sheets.

[0003] The prior art detects the surface defects of galvanized sheets through a vision sensor cooperating with a tooling connected to the galvanized sheet. When the galvanized sheet is clamped by the tooling without leveling treatment, it may affect the detection accuracy of the surface defects of the galvanized sheet. Because the galvanized sheet may warp when clamped by the tooling, resulting in light errors in the shooting of the vision sensor, thus affecting the detection accuracy of the surface defects of the galvanized sheet. Therefore, a clamping tooling for detecting surface defects of galvanized sheets is proposed to solve the above technical problems. Content of the Utility Model
