KR-102961616-B1 - Image acquisition device for printed circuit boards

Abstract

The present invention relates to an image acquisition device for a printed circuit board. The disclosed image acquisition device for a printed circuit board is a device for acquiring an image of a printed circuit board necessary for inspecting a printed circuit board, and comprises a device frame, a picker member, a substrate support plate member, an image acquisition member, and a plate transfer member. Since the substrate support plate member comprises a substrate support plate body and a substrate levitation air discharge hole, the printed circuit board is placed on the substrate support plate member in a levitation state, thereby preventing damage to the printed circuit board, such as scratching the surface of the printed circuit board, during the image acquisition process of the printed circuit board.
