Technical Field

[0001] The utility model relates to the technical field of waterproof breathable membrane detection, and more specifically to a device for detecting the flatness of a waterproof breathable membrane. Background Art

[0002] The trend for electronic products is shifting from waterproofing the entire device to waterproofing its components. Currently, waterproofing entire components is achieved by attaching waterproof and breathable membranes. Before applying these membranes to entire components, spot checks are conducted to confirm their quality. This prevents the use of unqualified materials in large quantities, which can lead to costly losses.

[0003] There are two existing methods for testing waterproof breathable membranes: one is to test the flatness of a sheet-like carrier membrane containing multiple waterproof breathable membranes; the other is to test the membrane by attaching it to a metal carrier.

[0004] Both of the above-mentioned detection methods require manual movement of the optical lens according to the product spacing during the detection process, resulting in low detection efficiency. In addition, the existing optical lens detection method has low product detection accuracy, and small concave, convex or damaged defects have the risk of escape. Utility Model Content
