During operation, the inspection platform 100 fixes the semi-finished breathable film, and the bottom light 110 located below irradiates the semi-finished breathable film upward. The light passing through the hole forms an image that is captured by the CCD electronic lens 120 and input to the host 130. The computer program of the host 130 recognizes and determines whether there is a foreign object at the position of the inner hole through the color difference at a specific position. If a foreign object is identified, the display 140 displays the position of the foreign object at the inner hole of the semi-finished breathable film so that the operator can eliminate the defect. Therefore, the inner hole of the semi-finished breathable film can be inspected to achieve the purpose of reducing the defect rate and improving the inspection efficiency.
