<p>Provided is a method for detecting whether there are components in a carrier tape by a photo sensor. The method for detecting whether there are the components in the carrier tape using an optical displacement sensor includes the following four steps. In a first step, the displacement sensor measures the displacement of a plurality of empty pockets in the carrier tape. In a second step, a first range of the displacement to determine the empty pocket is set by statistically processing the measured displacement of the empty pockets. In a third step, the displacement sensor measures the displacement of the pockets in the carrier tape. In a fourth step, a pocket is determined as the empty pocket if the measured displacement of the pocket is within the first range, and a component is determined to be in the pocket if the measured displacement of the pocket is outside the first range.</p> |
