Abstract: An equipment automatic alignment method and a process robot device using the same are provided. The equipment automatic alignment method includes following steps. An image of an equipment is obtained. The image is enhanced to obtain a plurality of candidate patterns. Each of the candidate patterns is expanded to obtain a first rectangular block and a second rectangular block. A plurality of first target patterns are obtained according to the first rectangular block, and a plurality of second target patterns are obtained according to the second rectangular block. A first base point is obtained from the first target patterns, and a second base point is obtained from the second target patterns. An operation command is generated according to the first base point and the second base point to automatically control an operation interface of the equipment, so that the first base point is aligned with the second base point.
