    • A gripping device for grasping and releasing articles by freezing and thawing water between a gripping surface and the article. The device includes a base plate, a mesh like gripping surface, a water passage to the gripping surface, a freezing element for freezing the water and bonding the gripping surface to the article and a thawing element for melting the frozen bond for releasing the article. The cooling and thawing elements use semi-circular tubing extending from the base plate and adjacent the gripping surface, through which are introduced a coolant for freezing the water and a heated liquid for thawing. Upon movement of the water via an atomizer to the gripping surface, coolant is introduced into the tubing to freeze the same. Upon freezing, the article and gripping surface become bonded. To release the article, the heated fluid is moved through the tubing so as to thaw the frozen bond.
    • 一种夹持装置,用于通过在夹持表面和制品之间冻结和解冻水来抓取和释放制品。 该装置包括基板,网状抓握表面,到抓握表面的水通道,用于冷冻水并将抓持表面粘合到制品上的冷冻元件和用于熔化冻结的解冻元件以释放物品。 冷却和解冻元件使用从基板延伸并且靠近抓握表面的半圆形管道,通过该管道引入用于冷冻水的冷却剂和用于解冻的加热液体。 当水通过雾化器移动到抓握表面时,将冷却剂引入管道中以使其冷冻。 在冷冻时,制品和夹紧表面变粘合。 为了释放制品,将加热的流体移动通过管道以解冻冷冻粘合剂。
