Vacuum suction pen for handling objects and materials to avoid hand contact

Abstract

A vacuum suction pen to take reliable hold of objects of different shapes without manual contact includes a holder with an air duct penetrating the holder. A first sleeve is sleeved on one end of the holder, and a first adsorption module is movably arranged on the first sleeve to move along a first direction. The first suction nozzle can move in the horizontal direction, the second nozzle can move in the vertical direction, and the third suction nozzle can rotate around the holder. The positions and relative positions of each suction nozzle on the product to be lifted and manipulated can be adjusted, so as to more accurately locate the center of gravity of products with irregular shapes or of uneven materials, and so as to secure a stable hold on the objects.
