Further, the backplate 36 that frame links into an integrated entity is enclosed in the front side setting of the most previous soft pack cell unit of electrokinetic cell module of the present utility model and its setting, correspondingly, the rear side of last soft pack cell unit of electrokinetic cell module arranges and encloses with its setting the backplate that frame links into an integrated entity.That is; now to be enclosed frame institute by the setting that the backplate of both sides, front and back and being arranged side by side is stitched together coated in the outside of whole electrokinetic cell module; thus the protecting sheathing that formation one is complete; effectively can protect the soft pack cell of its inside, and the fixed housing for assembling soft pack cell can be saved.Further, arrangement of directly fitting between each soft pack cell, therefore can't increase the overall dimension of electrokinetic cell module.
Bus-bar of the present utility model is roughly rectangle, connect the bus-bar of anode ear and to connect the bus-bar of negative electrode lug positioned opposite side by side, interval, a lateral edges first-class spacing ground close to each other on two bus-bars arranges the width lug groove 21 corresponding with the lug thickness of soft pack cell, thus make bus-bar be comb shape, the positive and negative lug of soft pack cell successively screens in the lug groove of correspondence.Like this, during assembling, bus-bar easily from being displaced sideways, can making lug snap in lug groove, being conducive to realizing automatic Composition.In addition, as shown in Figure 4, the insulated substrate 22 that bus-bar comprises bottom and the welding copper coin 23 be embedded at insulated substrate upper surface, insulated substrate is made up of flame-proof ABS, welding copper coin and insulated substrate make integrative-structure by injecting molding die, thus make to form good insulation between the lower surface of bus-bar and soft pack cell unit, weld copper coin simultaneously and there is higher rigidity.
Finally, we also can arrange the protective cover 5 of an insulation in the upside of electrokinetic cell module, particularly, we can arrange hold-down nut 37 in the upper side edge centre position of enclosing frame that formalizes, and correspondingly, arrange screw via hole 51 in the centre of protective cover, and the hold-down screw be threaded with hold-down nut is set in screw via hole, thus make protective cover reliably be fixed on the upside of electrokinetic cell module, to carry out good covering to bus-bar, avoid being short-circuited.
The encapsulating structure of electrokinetic cell of the present utility model can be adopted and realize with the following method.
First the counterdie upper shed die cavity upward that mould put into by frame is enclosed in setting through for both sides, front and back, the profile that the shape being arranged on the die cavity on the die joint of counterdie encloses frame with setting is suitable, thus the sidewall making setting enclose frame lateral surface and die cavity fits.As previously mentioned, enclose in the forward edge of frame top in setting and there is lug draw-in groove and location notch, therefore, the upside of front side towards die cavity that frame has lug draw-in groove and location notch is enclosed in the setting be placed in die cavity, correspondingly, we need to arrange dodge groove accordingly at the formalize screens projection that encloses on rear side of frame and positioning convex place of the bottom surface of die cavity correspondence, thus make setting enclose screens projection on rear side of frame and convex to can be positioned on and dodge in groove accordingly, thus guarantee the to formalize accurate location and laminating of enclosing frame lateral surface and cavity lateral.We need to arrange the lug storage tank of rectangle in cavity lateral at corresponding lug draw-in groove place simultaneously, and corresponding counterdie lug storage tank position arranges the closed projection of rectangle on the die joint of patrix, the lug draw-in groove that corresponding setting is enclosed in the forward edge of frame top on the die joint of patrix and location notch place arrange corresponding fitting projection.It should be noted that, setting is enclosed frame and flame-proof ABS plastics can be adopted to make, or make with aluminium alloy, enclose frame side when mould molding to cave inward because of shrinking owing to formalizing, therefore, setting can be enclosed the arc that limit, the frame left and right sides is designed to evagination by us, and the action on the limit, the left and right sides of arc is between 3mm-5mm, and its preferred value is 4mm.Like this, the limit, the left and right sides that frame is enclosed in setting after mould molding can be straightened condition substantially, or there is the evagination of trace, we by setting enclose frame put into the die cavity of the counterdie of mould time, inwardly can extrude the limit, the left and right sides that frame is enclosed in setting, when setting is enclosed after frame puts into die cavity, the limit, the left and right sides that frame is enclosed in setting can outwards be ejected, thus fits tightly with the sidewall of die cavity.
Secondly frame is enclosed in the setting that the soft pack cell with lug puts into die cavity according to unified direction, positive and negative lug is then positioned at setting and encloses in the corresponding lug draw-in groove of frame, and the end that now positive and negative lug stretches out lug draw-in groove enters in the lug storage tank of counterdie;
Then make the patrix of mould move down to close up with counterdie, now the die joint of patrix and the die joint of counterdie are fitted, patrix then enters in the lug storage tank of counterdie at the closed projection of corresponding counterdie lug storage tank position and compresses lug, fitting projection on patrix die joint then enters in the lug draw-in groove and location notch that formalize and enclose frame, thus makes the die cavity of counterdie form closed cavity.Be understandable that, close projection shape and lug storage tank suitable, and the height of closed projection adds that the thickness of anode ear or negative electrode lug should equal the degree of depth of lug storage tank;
Now can be injected in die cavity by the sprue gate that patrix is communicated with die cavity by the PUR of molten condition, namely the PUR of melting fills the space formalizing and enclose between frame and soft pack cell.In order to be conducive to the flowing of the PUR of melting, we can arrange the U-bend folding of upper and lower two pairs of evaginations respectively in the left and right sides that frame is enclosed in setting, two U-bend folding intervals of often pair of U-bend compromise are arranged, thus relatively recessed encapsulation location notch is formed between two U-bend foldings, like this, form the groove of both sides, through front and back in the inner side that frame is enclosed in setting, be thus conducive to PUR and enclose flowing before and after in frame between both sides in setting;
When separating patrix after PUR cooling curing, frame and inner soft pack cell solidification all-in-one-piece soft pack cell unit are enclosed in setting now, and the lug of soft pack cell then stretches out setting and encloses outside frame;
Then with the push rod be arranged on below counterdie, soft pack cell unit is upwards ejected die cavity, the soft pack cell unit of profile rule can be obtained;
Again some soft pack cell unit stacked side are bundled into one with packaging ring, the anode ear in the lug of now all soft pack cell unit is arranged in anode ear string, correspondingly, all negative electrode lugs are arranged in negative electrode lug string.And, just screens is in the lug draw-in groove that the soft pack cell unit that rear side is adjacent is corresponding and the lug compressed in this lug draw-in groove for the screens projection of the soft pack cell unit of front side, and the positioning convex of the soft pack cell unit of front side then inserts in the location notch of adjacent rear side soft pack cell unit.Packaging ring can adopt the insulating tape with adhesive sticker, is wrapped in by insulating tape by the elongated slot that is spliced into of encapsulation location notch, each soft pack cell unit can be bundled into one;
The bus-bar then compartment of terrain on two edges being provided with lug groove relatively moves to anode ear displacement from both sides and puts and negative electrode lug position, makes positive and negative lug by screens in the lug groove of the bus-bar of correspondence;
Finally recline after positive and negative lug bending 90 degree on the busbar, then with laser-beam welding machine, positive and negative lug and bus-bar are welded together, thus the electrokinetic cell module that formation one is complete.
