PURPOSE: A multi-functional vacuum absorbing device is provided to improve the workability and to reduce manufacturing cost by controlling an up/down movement of a vacuum cup using one solenoid valve. CONSTITUTION: A multi-functional vacuum absorbing device(100) includes a cylinder body(10), a piston(20) movably installed in the cylinder body(10), a rod(30), and a sleeve member(40) moved along a length of the rod(30). One end of the rod(30) is coupled to the piston(20), and a vacuum cup(31) is mounted on the other end of the rod(30). A perforation hole(11) is formed at a lower end of the cylinder body(10). The perforation hole(11) is communicated with a vacuum path(15), which is selectively opened or closed by means of a solenoid valve(13). Vacuum pressure introduced through the vacuum path(15) is selectively controlled by means of the solenoid valve(13).
