Turnover jig 32 removes jig platform 3209 and is transferred to jig turnover pipeline 50, and battery core unloading device 62 is used for will be in jig
The Naked battery core 83 being staggeredly stacked to form on platform 3209 by positive and negative anodes stack of laminations is taken out.
The Naked battery core 83 that the present invention produces includes that at least one layer of 82, one layers of positive plate 81 of negative electrode tab are staggeredly stacked one
It rises；There is a side of the positive plate anode to draw ear, and there is a side of the negative electrode tab cathode to draw ear, outside the positive plate
Side is coated with positive diaphragm, is coated with negative electrode membrane bag on the outside of the negative electrode tab, and under regular situation, negative electrode tab 82 is than positive plate 81
Mostly a piece of, i.e., first is negative electrode tab 82, last a piece of and negative electrode tab 82.It is also possible to positive plate 81 than negative electrode tab more than 82 one
Piece.
The present invention relates to a kind of methods and its equipment for realizing that positive/negative plate quickly overlaps, and it is mutual to be suitable for positive and negative plate
Stacking is formed in the manufacture craft of naked battery core, and method includes: to make envelope positive plate and negative electrode tab respectively first, just by envelope
Pole piece and negative electrode tab are stacked into one group of positive/negative plate group, are delivered to positive/negative plate group by uniaxial adjustable spacing conveyer belt mechanism
It has enough to meet the need on the laminate in jig, after turnover jig is collected completely, is transferred to stacking station, pole piece positioning mechanism determines positive/negative plate
Position, turnover jig detach horizontally outward, and positive/negative plate is staggeredly stacked forms Naked battery core together, and battery core unloading device is by Naked battery core
It takes out, is transferred to next station.Dress is saved compared with traditional " Z " font lamination process using the lamination process when conveying
Piece send piece and takes the intermediate links such as piece, reduces the waiting time, and automatic operation stacks high-efficient, suitable high-speed production lines.
Embodiment of above be only preferred embodiments of the present invention will be described, not to the scope of the present invention into
