Method and apparatus for picking up work piece and mounting machine

摘要

A work piece pickup method is for sucking and holding a work piece attached on an adhesive sheet by means of a suction collet that is disposed above the work piece attached on the adhesive sheet in such a way as to be movable up and down for sucking and holding the work piece and a suction member that is disposed below the adhesive sheet in such a way as to be movable up and down so as to detach and transfer the work piece. The method comprises a sheet suction process for sucking and holding a lower surface of the adhesive sheet corresponding to the work piece by the suction member, and a work piece suction process for sucking and holding the work piece by the suction collet under a state in which the suction collet and the work piece are in a positional relationship spaced from each other so as to detach the work piece. A pickup apparatus and a mounting machine operate in accordance with the above method.
