Fig. 9 is refer to, pressure frame 6 is first fixed in assembling equipment, it is corresponding in the bottom surface of pressure frame 6 with manipulator
A piece of barrier film 5 is from left to right sequentially placed on the position of each unit lattice, for convenience of description, there is no harm in the horizon battery of six cells
Exemplified by, it is that first module lattice are sequentially placed a piece of barrier film 5 to the 6th cell therefore.
Then the horizontal positioned double polarity plate 1 on barrier film 5, specifically, is placed from first module lattice to the 6th cell
Three double polarity plates 1, the negative plate of first double polarity plate 1 (refers to the pole plate that negative active material is scribbled on double polarity plate 1
Area) first module lattice region is placed on, positive plate (referring to the pole plate area that positive active material is scribbled on double polarity plate 1) is placed on
Two cell regions, the negative pole of second double polarity plate 1 is placed on third unit lattice region, and positive pole is placed on the 4th cell area
Domain, the negative pole of the 3rd double polarity plate 1 is placed on the 5th cell region, and positive pole is placed on the 6th cell region.Implement one
In example, the separator outerplanar of double polarity plate 1 and two the groove for being embedded in the bottom recesses of pressure frame 6 and two sides is corrected
In 61.
Then a piece of barrier film 5 is put on every cell again, six units totally six barrier films, per a piece of double polarity plate 1
Positive pole and negative pole are placed with a piece of barrier film 5 respectively.
Then a piece of anode sub-pole plate 2 is placed in first module lattice again, the 6th cell places a piece of negative terminal sub-pole plate 3,
Second unit lattice and third unit lattice place a piece of double polarity plate 1, and its positive pole is located at third unit lattice region, and negative pole is located at the
Two cell regions, the 4th cell and the 5th cell place a piece of double polarity plate 1, and its positive pole is located at the 5th cell area
Domain, negative pole is located at the 4th cell region, and the end line of anode sub-pole plate 2 and negative terminal sub-pole plate 3 is outwardly directed to battery respectively in addition
The two ends of core, for example, from left to right there is the first to the 6th cell successively, then the end line of anode sub-pole plate 2 is towards a left side, negative terminal pole
The end line of plate 3 is towards the right side, and in one embodiment, equally, the separator outerplanar 41 and two on pole plate, which is corrected, is embedded in pressure frame
In the groove 61 of the bottom recesses of frame 6 and two sides.
Thus complete the assembling of positive negative one layer battery, can be all the way up superimposed successively according to the battery number of plies of assembling every
Film 5 and pole plate (double polarity plate 1, anode sub-pole plate 2 and negative terminal sub-pole plate 3).
Figure 10 is refer to, in this way, the arrangement of pole plate is according to from left to right, from top to bottom, (positive plate refers to positive and negative pole plate
Positive plate in anode sub-pole plate 2 and double polarity plate 1;Negative plate refers to the negative pole in negative terminal sub-pole plate 3 and double polarity plate 1
Plate) order that is staggeredly placed is placed, and the assembling for being to be coated by barrier film 5 up and down, completing whole battery of every pole plate.
Certainly, the two ends of separator 4 can also all paint glue in above process, afterwards toward the two sides of pressure frame 6
The quantitative epoxide-resin glue of injection in groove 61.
Afterwards, connected and fixed with pressure frame 6 with press-fiting machine equipment pressure cover plate 7 is depressed, the separator 4 on pole plate is firm
It is embedded in well on the groove 71 that pressure cover plate 7 is adapted with the outer engagement face 42 of separator 4, press-fits design pressure reachable
100kPa, makes the sealing that unit compartment is realized by extruding of separator 4;Again with glue stuffing pressure cover plate 7 and pressure frame 6
Phase access section.
By said process, the complete independent sealing of six unit compartments is realized with isolating.
Afterwards, to the end line at battery two ends, i.e., the end line difference cast welding that anode sub-pole plate 2 and negative terminal sub-pole plate 3 are exposed
Upper casting terminal 9, using the positive pole and negative pole as horizon battery.
Afterwards, from the safe valve opening 73 on pressure cover plate 7 by vacuumizing after the separately acid filling into each unit lattice,
Battery carries out acid filling chemical conversion, and control acid sets up the Capsule of safety valve 8, and seal up shell 10, covers battery cover 11, seals, as into
Product battery.
The application makes the separator 4 during assembling between levels pole plate be realized after press-fiting by the bonus point spacing body 4 between pole plate
Elastic tight is compressed to seal, and completes the sealing of battery core unit compartment, and by pressure frame 6 and pressure cover plate 7 to unit
Lattice surrounding completes sealing, realizes completely isolated, solve liquid leakage inside unit compartment and collaborate, it is to avoid inside battery is constantly in
String trellis state and internal-response differs during the storage or discharge and recharge caused, from putting between horizon battery unit compartment and each horizon battery
Electricity is inconsistent.
The application substantially increases the retention of charge and battery with two side terminals of battery, so as to greatly improve the reality of battery
Border service life.Simultaneously without filling wax process to filling wax in battery, therefore can subtract again as the horizontal level of traditional bipolarity,
More excellent acid dosing and charging method can be also used, raw material paraffin and cost of labor is saved.
Above content is to combine the further description that specific embodiment is made to the application, it is impossible to assert this Shen
Specific implementation please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off
On the premise of from the present application design, some simple deduction or replace can also be made.
