Abstract:
A soldering apparatus for connecting solar cells (1) includes an induction heat source to connect cell conducting tracks, provided with soldering medium, with electric conductors. The heat source has a high-frequency generator and an inductor loop (32) in which the flow of a high-frequency current causes a high- frequency magnetic field to induce in the conducting track and in the electric conductor arranged along the conducting track eddy currents that generate the heat that is necessary for the soldering operation. The inductor loop (30) includes a U-shaped loop element that has narrowings and widening in one arm (31) that is positioned closer to the conductor. Ferrite beads (31) and ferrite tubes at the widening concentrate the magnetic field to optimize the heat development in the soldering zone and thus also save energy.
Abstract:
Inductive heating is added to a metal working process, such as a welding process, by an induction heating head. The induction heating head is adapted specifically for this purpose, and may include one or more coils (36) to direct and place the inductive energy, protective structures, and so forth. Productivity of a welding process may be improved by the application of heat from the induction heating head. The heating is in addition to heat from a welding arc (50), and may facilitate application of welding wire electrode materials into narrow grooves and gaps, as well as make the processes more amenable to the use of certain compositions of welding wire, shielding gasses, flux materials, and so forth. In addition, distortion and stresses are reduced by the application of the induction heating energy in addition to the welding arc source (16).
Abstract:
The present invention relates to an arm-type solder for a connector, and the arm-type solder for the connector, according to the present invention, comprises: a coil portion (10) which encircles the outer circumferential surface of a socket (2) of a connector (1); and an arm (20), which accommodates therein a wire for receiving power from the outside and supplying power to the coil portion (10), has a plurality of frames (201, 202, 203) which are coupled consecutively, and which is provided with a link at a coupling area so that an angle can be adjusted. According to the present invention illustrated above, the coil portion, having one open side in a Y-shape, encircles the outer circumferential surface, a ball lead is inserted into the socket and instantly molten using a high-frequency wave, and a wire is inserted, thereby providing the advantage of a simple and quick soldering process for connecting the connector and the wire.
Abstract:
La présente demande décrit un procédé et un dispositif de contrôle pour le brasage par induction en transparence. Le dispositif de contrôle pour un dispositif de brasage comprend : a) des moyens pour maintenir au moins partiellement face à face deux pièces (1; 3, 3') à solidariser avec un fil de brasure plat (5, 5') intercalé entre les deux pièces (1; 3, 3'); b) des moyens de serrage (2, 4) des deux pièces (1; 3, 3') l'une vers l'autre; c) un inducteur (6) disposé au voisinage des deux pièces (1; 3, 3'); d) des moyens d'activation (8) de l'inducteur (6) pour faire fondre par induction le fil de brasure (5, 5') intercalé entre les deux pièces (1; 3, 3') serrées l'une contre l'autre; et e) un dispositif (9) de contrôle de la variation de l'écartement entre les faces confrontées des deux pièces (1; 3, 3') pendant la phase d d'activation de l'inducteur (6) adapté pour que cette variation quand elle est comprise dans une plage de déplacement définie permette d'assurer que la brasure est bien passée en phase liquidus.
