Abstract

A vacuum tool for picking up a part in the course of robotic assembly has a datum surface against which the part is held during transport and assembly. A deformable sleeve completely surrounds, and protrudes beyond, the datum surface and provides a seal between the tool and the part to be picked up when a vacuum is initially applied. As the suction increases, the sleeve deforms and the part is drawn into contact with the datum surface. The tool shown in the figure has a cylindrical body 1 with a longitudinal bore 2 to which the vacuum is applied. A face 3 of the body 1 is accurately machined to provide the datum surface, and is surrounded by a deformable sleeve 4, one edge 5 of which extends beyond the datum surface of the tool.

Vacuum Tool for Robotic Assembly

A vacuum tool for picking up a part in the course of robotic assembly has a datum surface against which the part is held during transport and assembly. A deformable sleeve completely surrounds, and protrudes beyond, the datum surface and provides a seal between the tool and the part to be picked up when a vacuum is initially applied. As the suction increases, the sleeve deforms and the part is drawn into contact with the datum surface. The tool shown in the figure has a cylindrical body 1 with a longitudinal bore 2 to which the vacuum is applied. A face 3 of the body 1 is accurately machined to provide the datum surface, and is surrounded by a deformable sleeve 4, one edge 5 of which extends beyond the datum surface of the tool. The sleeve 4 is cast from soft polyurethane and is held in place by means of a circular flange 6 around the body of the tool.
