METHOD FOR MANUFACTURING LEAD GRIDS FOR BATTERY ELECTRODES.

摘要

A method for manufacturing lead grids for battery electrodes, characterized in that it comprises the following steps: providing a lead strip at a cutting and ablation station, cutting said lead strip by means of at least one laser beam that cuts and reduces the thickness of said lead strip forming a lead grid, supporting said lead strip, at least at said cutting and ablation station, without interfering with said laser beam. The lead strip may be supported in a limited number of discrete positions of the lead strip, said discrete positions being as little as possible coincident with the cutting positions of said at least one laser beam. Alternatively, the lead strip is supported by means transparent to the wavelength of said laser. The laser beam is focused and moved by a generally remote scanning and/or proximity head, which is preferably mounted on a motion system which controls its position according to a selected cutting path and controls the position of the focus. The process allows continuous control of the path and or parameters of cutting and/or ablation by means of software.
