Roller tool and positional pressure method of use for the forming and joining of sheet material
First Claim
1. An apparatus for forming and joining a first sheet material to a second sheet material, the apparatus comprising:
- a nest for holding the first sheet material;
a robotic arm operatively associated with said nest;
a faceplate rotatably attached to said robotic arm, said faceplate having a long axis; and
a positional pressure roller tool for forming and joining the first sheet material to the second sheet material, said positional pressure roller tool including a cylinder rigidly attached to said faceplate, a reciprocating hub including a piston end and a roller tool end, said reciprocating hub being reciprocatingly mounted in said cylinder, and a main roller tool, said main roller tool being mounted to said roller tool end of said reciprocating hub, said reciprocating hub having a long axis, said long axis of said reciprocating hub and said long axis of said faceplate being in axial alignment, said roller tool including a roller, said roller being positioned off-axis with respect to said long axis of said reciprocating hub.

Abstract
An apparatus and method for forming and joining a first sheet material (A) located in a nest (30) to a second sheet material (B) positioned on top of the first sheet material. The apparatus includes a positional pressure roller tool or positional pressure variance unit (50) for performing the forming and joining operations. The PPVU (50) may include both a main roller (58) and a touch-up roller (60). The PPVU (50) is operatively associated with a programmable positioning apparatus in the form of a robotic arm (52) and a machine cell (10) whereby the position of the robotic arm (52) relative to the nest (30) dictates the applied pressure at the interface between the roller (72) and the nest (30).
