Abstract:
A mechanism for positioning a substrate of an image sensor, the substrate having a first edge, a second edge, a third edge and a fourth edge, the mechanism comprising:a standard unit having a first standard plane and a second standard plane perpendicular and adjacent to the first standard plane, the first standard plane and the second standard plane defining a positioning region in which the substrate is positioned, and the first edge and the second edge adjacent to the first edge contacting the first standard plane and the second standard plane, respectively; a link unit including a first link and a second link pivotally mounted to the first link at a pivotal portion for positioning the third edge of the substrate; and a push-up needle unit for positioning the fourth edge of the substrate, wherein when the link unit operates, the push-up needle unit and the pivotal portion of the link unit are moved toward the fourth edge and the third edge of the substrate, respectively, to position the substrate.
