From the above, the specific working principle of the integral folding and packaging mechanism 3 is as follows:

firstly, placing the cut aluminum foil on a folding plate 311 which is horizontal in the X axis direction through a negative pressure manipulator; the battery core is placed on the dotted line frame part of the right folding plate 311 in fig. 2 through a negative pressure manipulator, and the battery core is placed on the surface of the aluminum foil, wherein one side of the dotted line frame is a reserved air bag position.

Then, the two folding plates 311 are driven to rotate in opposite directions, specifically referring to the change from the diagram a to the diagram b in fig. 3, after being folded, the two folding plates 311 clamp the aluminum foil and the battery cell; in the process, two stop rods 336 in the filling assembly 33 define the bent portion of the aluminum foil, and are positioned below the battery cell after being folded, as shown in fig. 3 b. In addition, as can be seen from fig. 1, the position-limiting rod 336 is positioned on the folding plate 311 at a position where the air bag is reserved.

Then, the lifting columns 332 are activated to drive the two limiting rods 336 to lift up along the Z-axis direction, in the process, a stretching operation is performed on one side of the aluminum foil reserved air bag, and when the limiting rods 336 lift up to the highest position, the side is corresponding to the secondary pressing plate and is not higher than the vertical heat-sealing pressing plate 315, specifically referring to the changes from the diagrams b to c in fig. 3.

Next, the vertical hot press head 322 and the preliminary press head are driven by the electric push rod 324 to approach the folding plate 311 and contact with the corresponding T-shaped contact 317, so that the vertical hot press plate 315 and the preliminary press plate are pressed by the T-shaped contact 317, thereby forming a side seal, a top seal and a primary seal after the aluminum foil is folded, specifically referring to the variation from the diagrams c to d in fig. 3. Wherein, the first region of sealing is located the top of sealing the region once more, and the corresponding pressure head that is promptly is located inferior pressure head below, guarantees from this that the aluminium foil of encapsulation bagging-off can effective splendid attire electrolyte, and avoids appearing the problem that electrolyte was revealed.

After the above-mentioned encapsulation is accomplished, based on the injecing of gag lever post 336 for the aluminium foil in the sealed region once more is strutted, thereby forms the filling position, drive filling stand 333 and be close to lift stand 332 from this, so that filling head 337 passes positioning through-hole 335, and stretch into to the aluminium foil of encapsulation bagging-off in, under this state, can pour into electrolyte into the aluminium foil encapsulation bag through filling head 337, refer to e picture state in fig. 3 specifically, under this state, because the opening of filling position is less, and the opening is strutted by gag lever post 336, can effectively avoid the problem that electrolyte revealed to appear in the filling process from this. In addition, the whole process is automatic operation, manual participation is not needed, and the working efficiency can be greatly improved.

After filling is completed, the lifting upright column 332 and the filling upright column 333 are driven to synchronously move along the first Y-axis guide rail 331 so as to draw out the limiting rod 336 and the filling head 337 from the aluminum foil packaging bag, and the electric push rod 324 corresponding to the secondary pressure head is immediately started after the drawing out so as to drive the secondary pressure plate to compress based on the same principle, so that the secondary sealing of the filling position is realized, and therefore, the complete filling, the side sealing, the top sealing, the primary sealing and the like of the whole aluminum foil packaging bag are realized, and the state of a diagram f in fig. 3 is specifically referred. Under the state, because the opening of the filling position is smaller and the filling position is packaged in time, the contact time of the electrolyte and the air can be effectively reduced, and the quality of the finally packaged and molded battery is greatly improved. In addition, since the spring 318 is compressed when any one of the T-shaped contacts 317 is pressed, the return of the corresponding pressure plate can be automatically realized by the rebound of the spring 318 after the return electric push rod 324 is retracted.
