Background technology
Traditional square lithium ion battery winding winding apparatus is the fixing chip volume pin of width mostly, and the continuous promotion and application in various electrical equipment along with battery, the demand also more and more to the individual requirement of battery design, that comparatively single model exploitation fully can not satisfying the market.Therefore, in order to meet the diversified requirement of battery core " flexibility ", width adjustable battery coiler device has appearred.
The shortcoming of the cell winding device in the battery core production equipment of prior art is: 1, one pair of coiler device a kind of battery core of specification of can only correspondingly reeling, waste resource; When 2, the coiling model is changed, the installation that requires a great deal of time, correction.
The utility model content
The technical problems to be solved in the utility model is: the deficiency existed for above-mentioned prior art, a kind of cell winding device for the battery core production equipment is provided, and adopt broad-adjustable volume pin.
The technical scheme that the utility model proposes for the problems referred to above is: a kind of width tunable winding needle comprises body portion and movable part; Wherein, body portion be the pair of parallel symmetry determine the volume pin, with cell winding device, be connected; The moving volume pin that movable part is the pair of parallel symmetry, be connected to a pair of outside of surely rolling up pin; Described surely the volume between pin and moving volume pin is provided with at least pad of a slice change volume pin width; Described moving volume pin is fixed on the outside of determining the volume pin by screw and alignment pin.
Wherein, described body portion is provided with at least two screwed holes that are screwed into for screw along its length; Described movable part corresponding screwed hole position along its length is provided with the through hole passed for above-mentioned screw.
Wherein, described movable part is provided with at least two alignment pins that stretch out along its length; Described body portion is provided with the pin-and-hole inserted for above-mentioned alignment pin along its length.
Another technical scheme that the utility model pin proposes is: a kind of cell winding device comprises above-mentioned width tunable winding needle.
Compare with the cell winding device of prior art, adopt the advantage of technical solutions of the utility model to be: 1, broad-adjustable volume pin is for cell winding device, and the width of volume pin is precisely controlled; 2, in the one fixed width scope, the electric core winding of energy suitable for various size
;3, the volume pin is simple in structure, and low cost of manufacture is regulated the speed fast, can make the time of adjusting volume pin width be shortened, and has promoted the production efficiency of battery core.
