1. A pressure activation apparatus with a transfer unit, comprising:
a loading section configured to load a tray in which a plurality of secondary battery cells is accommodated;
a transfer section configured to transfer the plurality of secondary battery cells accommodated in the tray to a buffer section;
the buffer section configured to accommodate in a buffer the plurality of secondary battery cells transferred by the transfer section; and
a jig section configured to perform a pressure activation process after the plurality of secondary battery cells accommodated in the buffer is transferred and mounted by a pick-and-place,
wherein the transfer section comprises transfer unit configured to transfer the plurality of secondary battery cells accommodated in the tray to the buffer in once or twice
wherein the transfer unit includes:
a plurality of first-side pickers configured to grip a first side of each of the plurality of secondary battery cells;
a plurality of second-side pickers configured to grip a second side of each of the plurality of secondary battery cells;
an opposite-side picker group space adjuster configured to adjust a space between the plurality of first-side pickers and the plurality of second-side pickers; and
an inter-picker space adjuster configured to adjust a space between pickers making up the plurality of first-side picker and a space between pickers making up the plurality of second-side pickers,
wherein the picker includes:
a connection block connected to a sliding bar, which is configured to connect the picker to an adjacent component of the transfer unit,
a picker actuating body configured to generate a driving force;
a moving block configured to move vertically based on the driving force of the picker actuating body;
an opening and closing block coupled to a lower portion of the moving block to move vertically along with the moving block,
a pair of grip blocks configured to directly contact the secondar battery cell to grip the secondary battery cell, and coupled to the opening and closing block to be opened and closed based on vertical movement of the opening and closing block, the pair of grip blocks moving away from each other to be separated from the secondary battery cell for releasing the secondary battery cell, by downward movement of the opening and closing block, and moving close to each other to be in contact with the secondary battery cell for gripping the secondary battery cell, by upward movement of the opening and closing block; and
a support block configured to support bottom portions of the pair of grip blocks to guide the pair of grip blocks to be opened and closed.
