Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method and apparatus for alternately stacking storage battery plates with separators interposed therebetween.

Prior Art and its Problems In recent years, a large amount of research and development has been carried out regarding small sealed storage batteries, and many applications have been filed regarding the same. Among them, JP-A-53-149636 discloses a storage battery in which negative and anode plates are alternately interposed in the upper opening of a series of microporous sheets folded in the vertical direction. Conventionally, the assembly of such storage batteries was almost entirely done by hand. In particular, when a fine glass fiber mat is used as the microporous sheet, the mechanical strength of the mat is weak, so it is not suitable for automatic assembly techniques using mechanization.

OBJECTS OF THE INVENTION The present invention solves the above problems and provides a method and apparatus for automatically stacking storage battery plates.

Structure of the Invention In the method of the present invention, after placing a cathode plate and an anode plate on a slide unit, a folding plate and an auxiliary folding plate are used to fold the separator vertically. The anode plates are alternately positioned by reciprocating the slide unit, and then the separators are folded vertically at the pleats, and one side of the separators is opened on a table that has the function of keeping the stacking height constant. The method is characterized in that the negative and anode plates are alternately inserted and stacked using a pick-and-place method, and when a predetermined number of plates are stacked, the separator is cut.

The device of the present invention also includes a pleat section that has a function of vertically folding a separator using a folding plate and an auxiliary folding plate, and a slide unit on which a cathode plate and an anode plate are placed and positioned in front of the pleat section. , a pick and place for alternately inserting the negative and anode plates into one opening of the separator folded at the pleats, a table having a function of keeping the stacking height constant, and a cutter for cutting the separator. It is characterized by being configured with the following.

Embodiment An embodiment of the present invention will be described in detail based on the drawings. FIG. 1 is a side view of the apparatus of the present invention, and FIG. 2 is a front view of the same from FIG. 1 with the slide unit 1 omitted. FIG. 3 is a schematic plan view of the apparatus of the present invention, and FIG. 4 is a side sectional view taken along line A-A' in FIG.

In the method of the present invention, the slide unit 1 is connected to the cathode plate 2.
The cathode plates 2a, 2b,
2c and anode plates 3a, 3b, and 3c (not shown) are separated and placed on the slide unit 1 so as to protrude, and then the separator 8 is folded vertically using the folding plate 6 and the auxiliary folding plate 7. The cathode plates 2a to 2 are placed in front of the pleated portion 9, which has the function of
c and anode plates 3a to 3c are alternately positioned by reciprocating the slide unit 1. Here, the separator 8 is made of a fine glass fiber mat, is fed from a separator roll 10 through a pull-out roller 11, and is given an appropriate tension by a tension roller 12. Next, the cathode plate 2 is placed on the table 13, which has a function of keeping the stacking height constant, using the pick and place 15, and then the separator 8 is vertically folded at the pleat part 9, and On the table 13, the cathode plates 2 and the anode plates 3 are alternately inserted into the opening 14 of the separator 8 using the pick-and-place 15, and stacking is repeated until a predetermined number of plates are stacked.

After finally stacking the cathode plates 2, the cutter receiving plate 16 is lowered and the cutter 17 moves forward to cut the separators 8, thereby completing the electrode plate group 18.
FIG. 5 is a side view of the completed electrode plate group. Thereafter, the plate group 18 is conveyed to the conveyor 19 by the lowering of the table 13, and is moved to the next step.
Note that the cut separators 8 are adsorbed and held by the folding plate 6 because the folding plate 6 is provided with an air suction section, and the next stacking can be carried out smoothly.

Next, regarding the function of the pleat portion 9, Section 6-1
A more detailed explanation will be given based on FIGS. 6-4.

(Processes shown in Figures 6-1 to 6-2) Separator 8 is made using folding plate 6 and auxiliary folding plate 7.
After making the creases, the folded plate 6 is horizontally laid down and the separator 8 is stacked on the cathode plate 2.
Thereafter, the anode plate 3 placed on the slide unit 1 is stacked on the separator 8 using a pick and place 15. Note that the pick-and-place 15 is equipped with an air suction section at its tip, and can pick up and carry the anode plate 3.

(Processes shown in Figures 6-2 to 6-3) After pulling out the folding plate 6 while holding the anode plate 3 with the pick-and-place 15 and moving it back, the presser plate 20 is lowered to press the anode plate 3. At the same time, the auxiliary folding plate 7 becomes horizontal. Furthermore, the table 13 is lowered by the thickness of the stacked separators 8 and anode plates 3, thereby keeping the stacking height constant.

(Processes shown in FIGS. 6-3 to 6-4) As the pick-and-place 15 moves to a predetermined position, the folding plate 6 moves forward and stands up vertically while pressing the anode plate 3 with the presser plate 20.

(Steps from FIG. 6-4 to FIG. 6-1) As the presser plate 20 rises, the auxiliary folding plate 7 lowers, and the separator 8 is folded.

By repeating the above steps, a predetermined number of negative and anode plates 2, 3 and separators 8 are stacked to complete the electrode plate group 18. Note that the number of electrode plates can be set arbitrarily.

Effects of the Invention As described above, the present invention can automate the stacking of storage battery plates, which has conventionally been done manually, using a simple method and device. Furthermore, since a plurality of electrode plate groups (three in the above embodiment) can be stacked at the same time, the storage battery assembly space can be used efficiently and productivity can also be improved.
