Device for welding electrode plates of the same polarity in an accumulator

摘要

A device for welding plate tabs (2) of electrode plates (1) of the same polarity in a stacked plate stack in an accumulator to one another and to at least one terminal (12), having a shape which is formed by a centre strip (4) (which can be moved in between the plate tabs (2) of different polarity), a comb structure (5) (which can be moved in between the plate tabs (2) from the outside) and an outer terminating strip (6) positioned at a distance from the plate tabs (2), it being possible to insert the terminal (12) between the terminating strip (6) and the plate tabs (2), simultaneous and automatic welding of all the plate tabs (2) of the electrode plates (1) of the same polarity in a plate set is made possible by flat heating devices (8) above the rows which are formed by plate tabs (2) of electrode plates (1) of the same polarity and can be lowered tightly over the plate tabs (2), and by means of a screen (10) which is located between the respective heating device (8) and the associated terminal (12). <IMAGE>
