(2) use arc tape measure vertically to reel to anode pole piece, cathode pole piece and barrier film, described arc tape measure comprises the fixed part that is connected with winding apparatus and for the fixing winder of anode pole piece, cathode pole piece, barrier film, in the middle of described winder, be provided with strip breach winding part is become to symmetrical halves, one side of described winder is plane, opposite side is arcwall face, the calculating of arcwall face:
The width F=B-D of arc tape measure
The arc length H=F+E of arc tape measure;
Wherein, in arc battery, arc length is B, and the Winding Layer of arc battery is C, and the thickness of arc battery is D, and the central angle radius of arc battery is R, first the thickness D of arc battery is carried out to N decile, and N=(C-2), the arc length difference of every equal portions is E;
(3), after having reeled, at the pad welding positive pole ear of anode pole piece, in the pad welding negative lug of cathode pole piece, produce arc battery core;
(4) utilize and to rush box mould punching and go out upper casing and the lower casing with arc groove, one end of upper casing and lower casing links into an integrated entity;
(5) arc battery core is put into the arc groove of lower casing, then upper casing is turned down with lower casing and coordinated, utilize arc end socket to carry out edge sealing at upper casing and lower casing edge, and reserve liquid injection port;
(6) battery core changes into the upper fixture in front and back, makes barrier film and pole piece generation polymerization, is bonded together closely.
As improvement, the direction of described positive pole ear and negative lug is consistent with coiling direction.
As improvement, the described box mould that rushes comprises arc drift, and the radian of arc drift is identical with the radian of finished product arc battery.
As improvement, after having reeled, the empty paper tinsel of reserved 3 to 5mm lug spot welding position.
As improvement, the described box mould that rushes comprises arc end socket, and arc end socket is provided with arc cavity, arc cavity both sides keep away glue groove.Arc end socket is for stamping out upper casing and the lower casing with arc groove; If do not keep away glue groove, produce several after, glue remains on end socket, also can cause sealing-in thickness not up to standard, sealing-in effect is defective.
As improvement, on arc end socket, be provided with guide pillar, end socket is when punching press, can not depart from run trace, for arc battery, because arc cell package precision requirement is higher, if the upper casing being stamped out and lower casing deviation are larger, directly can cause the encapsulation failure of arc battery.
The beneficial effect that the present invention compared with prior art brought is:
The coiling that utilization matches and rush box mould, makes produced battery itself with regard to camber, does not need battery to carry out bending by force, can preserve inside battery structure and not be damaged.
