A vacuum pickup tool (11), capable of picking up components (26) having a wide range in size and weight, comprises a body (12) having shaft (14) extending therefrom. The end of the shaft furthest from the body has an orifice (18) surrounded by a sealing surface (22) adapted for contact with a planar surface (24) on the component to form a substantially airtight seal therewith. A sleeve (30), having a rim (32) at the end thereof, is slidably carried by the shaft for movement thereon between a first and second position. At the first position of the sleeve, the sealing surface (22) at the end of the shaft extends beyond the rim (32) so that the sealing surface may contact the component, enabling a vacuum to be drawn over a first sized vacuum area on the surface of the component when the vacuum is drawn through the orifice. At the second position of the sleeve (30), the rim (32) extends beyond the sealing surface (22) for contacting the component surface ( 24) to enable a vacuum to be drawn over an area larger than the first vacuum area when a vacuum is drawn through the orifice (20).

Abstract

A vacuum pickup tool (11), capable of picking up components (26) having a wide range in size and weight, comprises a body (12) having shaft (14) extending therefrom. The end of the shaft furthest from the body has an orifice (18) surrounded by a sealing surface (22) adapted for contact with a planar surface (24) on the component to form a substantially airtight seal therewith. A sleeve (30), having a rim (32) at the end thereof, is slidably carried by the shaft for movement thereon between a first and second position. At the first position of the sleeve, the sealing surface (22) at the end of the shaft extends beyond the rim (32) so that the sealing surface may contact the component, enabling a vacuum to be drawn over a first sized vacuum area on the surface of the component when the vacuum is drawn through the orifice. At the second position of the sleeve (30), the rim (32) extends beyond the sealing surface (22) for contacting the component surface ( 24) to enable a vacuum to be drawn over an area larger than the first vacuum area when a vacuum is drawn through the orifice (20).
