(2) use arc tape measure that anode pole piece, cathode pole piece and barrier film are vertically wound, described arc tape measure includes the fixed part being connected with winding apparatus and for fixing the winder of anode pole piece, cathode pole piece, barrier film, it is provided with strip breach in the middle of described winder and winding part is become symmetrical two halves, the 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
Arc length H=F+E of arc tape measure；
Wherein, a length of B of arc battery inner arc, 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 N decile, N=(C-2), the arc length difference of every equal portions is E；
(3) after having wound, the pad at anode pole piece welds positive pole ear, and the pad at cathode pole piece welds negative lug, produces arc battery core；
(4) utilizing and rush box mould punching and go out the upper casing with arc groove and lower casing, upper casing links into an integrated entity with one end of lower casing；
(5) arc battery core is put into the arc groove of lower casing, then upper casing is carried out turnover and coordinates with lower casing, utilize arc end socket to carry out edge sealing at upper casing and lower casing edge, and reserve liquid injection port；
(6) upper fixture before and after battery core chemical conversion, makes barrier film and pole piece be polymerized, is bonded together closely.
As improvement, described positive pole ear is consistent with coiling direction with the direction of negative lug.
As improvement, the described box mould that rushes includes arc drift, and the radian of arc drift is identical with the radian of finished product arc battery.
As improvement, after having wound, reserved 3 to 5mm lug spot welding sky paper tinsel position.
As improvement, the described box mould that rushes includes that arc end socket, arc end socket are provided with arch shaped cavity, arch shaped cavity both sides keep away glue groove.Arc end socket is for stamping out the upper casing with arc groove and lower casing；Without keeping away glue groove, produce several after, glue remains on end socket, also results in sealing-in thickness the most up to standard, and sealing-in effect is defective.
As improvement, being provided with guide pillar on arc end socket, end socket is when punching press, do not deviate by run trace, for arc battery, owing to arc cell package precision requirement is higher, if the upper casing being stamped out and lower casing deviation are relatively big, the encapsulation failure of arc battery directly can be caused.
The present invention is compared with prior art had the benefit that
Utilize the winding matched and rush box mould, making the battery inherently camber manufactured, it is not necessary to battery is carried out bending by force, it is possible to preserving inside battery structure without damage.
