PORTABLE ELECTROMAGNETIC INDUCTION WELDING DEVICE, AND METHOD TO JOIN ADHESIVE TAPES IN ELECTRICALLY CONDUCTIVE COMPOSITE MATERIALS WITH POLYMER MATRIXES THROUGH A WELDING DEVICE

摘要

A portable welding device (1) comprising: a base (3) facing a work surface (4), in turn designed to receive tapes (2) in electrically conductive composite materials to be joined or defined by at least one tape already positioned (2); an operational head (5) which receives a tape (2) at a time and movable with respect to the base (3) along at least one first line of movement (L1) parallel to the work surface (4); a motorized arm (6) connecting the operational head (5) to the base (3) and selectively activable to provide movement to the operational head (5); and feeding means (8) selectively activated to feed one ribbon (2) at a time to the operational head (5) and connected to the operational head (5); the operational head (5) comprises a positioning roller (9) which receives one tape (2) at a time; a pressure roller (10) spaced from and aligned with the positioning roller (9) along the first line of movement (L1); and an inductor (11) interposed between the positioning roller (9) and the pressure roller (10) with reference to the first line of movement (L1).
