Soldering device for fixing an electrically conductive strip to a solar cell

摘要

Soldering device (8) comprises: many suppressor elements for holding the tape on a surface of the electric busbar; and an induction antenna (10) with a current path for electric current extending along the soldering line, through which alternating electric current is passed along the current path to generate an alternating magnetic field in the soldering line or in a vicinity of the soldering line. The suppressor elements are designed such that they extend perpendicular to each soldering line, and extend in a soldering plane in which the soldering line is located. Soldering device (8) comprises: many suppressor elements for holding the tape on a surface of the electric busbar; and an induction antenna (10) with a current path for electric current extending along the soldering line, through which alternating electric current is passed along the current path to generate an alternating magnetic field in the soldering line or in a vicinity of the soldering line. The suppressor elements are designed such that they extend perpendicular to each soldering line, and extend in a soldering plane in which the soldering line is located. The suppressor elements are arranged in a row one behind the other such that a gap is formed between two of the suppressor elements which are arranged directly behind one another in series, and the respective suppressor elements are movable in the soldering plane relative to the soldering line. The current path is formed in an electrically conductive solid body, where the solid body comprises at least one portion extending substantially parallel to soldering line, which is separated from the soldering line by air gap, and in which at least a portion of the current path is formed. The portion extending parallel to soldering line comprises: many recesses which are arranged in a row one behind the other along the soldering line and extend along the soldering plane, vertical to the soldering line such that each of the suppressor elements are arranged to be movable in one of these recesses; and many sections, each of which has a longitudinal axis extending parallel to soldering line. The elongated sections are arranged between each pair of the recesses, which are arranged directly behind one another in a row where sections are in a straight line and parallel to the soldering line of the two recesses and extend along other two recesses. At least one elongated section comprises the portion of current path.
