A system for assembling, processing and transferring battery cell elements including a plurality of element assemblers and an exit conveyor having a plurality of element conveying lanes. Each element assembler includes element transfer and processing apparatus comprising an endless chain conveyor having a plurality of longitudinally spaced element carriers adapted to successively engage an element at a loading station, carry the engaged element through a plurality of process stations, and release the element at a discharge station. In the illustrated apparatus, the carriers each engage a loosely assembled element at the loading station, compress the element to final size, and carry the element through an inspection and manual unload station, a plate alignment station, a plate lug brushing station, a plate alignment after brushing station, and a series of tape applicator stations which bind the element in assembled and processed condition. The discharge station of each element assembler includes a transfer mechanism adapted to transfer assembled elements onto a selected one of a plurality of exit conveyor lanes in a manner that enables a uniform supply of elements for subsequent use in an automated battery production line.

Apparatus and method for processing and transferring battery cell

An apparatus and method for assembling battery cell elements having a plurality of electrode plates of alternating polarity separated by a continuous interleaved insulating sheet. The apparatus includes a separator sheet supply station; a creaser for forming transverse creases in a length of separator sheet at longitudinally spaced fold points; a first plate loader for positioning a first set of electrode plates of common polarity onto a pre-fold mechanism; a sheet transfer mechanism for transferring a cut and creased length of separator sheet from the creaser onto the first set of plates; a second plate loader for positioning a second set of electrode plates of common polarity opposite to that of the first set onto the separator sheet at locations directly above the plates of the first set; the pre-fold mechanism including a collapsible pre-fold paddle assembly for folding the separator sheet into relatively loose accordian folds with the plates of the first and second sets occupying alternate folds on opposite sides of the separator sheet; an intermediate fold mechanism for engaging the pre-folded element, positioning the plates thereof into relatively precise alignment, and compressing the element into a tighter intermediate folded assembly; and a final fold mechanism for engaging the intermediate folded assembly, compressing the assembly into final element form, transporting the element through a series of tape applicators to secure it in its final form and then to a discharge station. The apparatus includes a master controller that controls operation of the plurality of mechanisms to permit automatic and continuous high volume production of such battery cell elements.
