Patent ID: 8430384

Claim:
A device capable of picking up optical elements, comprising: a first suction member defining a chamber, and comprising at least one first suction tube communicating with the chamber; a second suction member arranged around the first suction member to form an annular space, and comprising at least one second suction tube communicating with the annular space, wherein the height of the at least one second suction tube is higher than that of the at least one first suction tube; a vacuum pump unit configured for pumping air out of the chamber and the annular space to create a vacuum therein, which generates a suction force to allow the at least one first suction tube to suck an optical element, and to allow the at least one second suction tube to suck another optical element below the optical element; and a liquid spraying unit communicating with the chamber and the annular space, and configured for pouring liquid into the chamber and the annular space, wherein when the liquid volatilizes in the chamber and the annular space to fill the vacuum, the another optical element disengages from the at least one second suction tube, and the optical element disengages from the at least one first suction tube.
