Abstract

PURPOSE:To continuously wrap a pasted pole plate with a separator without damaging the separator. CONSTITUTION:A pole plate 4 is wrapped by a separator while a two-fold separator 3 is being moved every definite interval. In this wrapping process, the pole plate 4 is inserted in between the separators, so that a part of the over lapped portion 3a of the aforesaid separator 3 is temporarily welded. And next, the whole of the over lapped portion 3c is welded.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of packaging a paste type electrode plate with a separator.

[0002]

2. Description of the Related Art Conventionally, when an anode plate of a prismatic nickel-cadmium battery is continuously packed with a separator, as shown in FIG. 4, every time the index table 1 is rotated by 90 °, it is folded in two through an electrode plate guide 2. Separator 3
The electrode plate 4 was inserted in the inside. Then, the overlapping portion 3a of the separator 3 is welded on the spot by ultrasonic waves or the like, and moved to the next step by a feeder that moves at regular intervals, and the electrode plate 4 is moved.
Was pushed by the air cylinder 5 to the bent portion of the separator 3.

[0003]

In the method described in the prior art, when the electrode plate 4 is pushed into the space between the separators 3 by the air cylinder 5, the surface of the electrode plate 4 is caught by the separator 3 and the separator 3 is damaged. There was something to do. In particular, the paste-type electrode plate obtained by applying the paste-like active material to the nickel mat and drying it has a poor sliding property on the separator 3 and the above problems are prominent, so that it cannot be continuously packaged. ..

The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for continuously packaging paste-type electrode plates without damaging the separator. is there.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention wraps an electrode plate (4) with the separator (3) while moving the separator (3) folded in two at regular intervals. In the method, the separator (3)
And a step of inserting an electrode plate (4) between them to temporarily weld a part of the overlapping part (3a) of the separator (3) and a step of welding the entire overlapping part (3a). It is a feature.

[0006]

[Operation] When the electrode plate is inserted between the separators and the electrode plate is inserted up to the fold of the separator and part of the overlapping portion of the separator is temporarily welded, it is not necessary to shift the electrode plate on the separator Is fixed, the electrode plate is not displaced during the movement to the next process.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view showing an embodiment of the present invention, in which an index table 1 is a clamp 1a for holding an anode plate 4 and is 90
Rotate every °. Reference numeral 2 makes it easy for the electrode plate 4 to be inserted between the separators 3 folded in two by the electrode plate guide.
The separator 3 is placed on a feeder (not shown) that moves at regular intervals (intervals indicated by arrows in the figure).

Next, the manufacturing method of the present invention will be described. Figure 1
As described above, the anode plate 4 gripped by the clamp 1a of the index table 1 is rotated by 90 ° and is inserted up to the bent portion of the separator 3. FIG. 2 is a sectional view taken along the line AA ′ of FIG. 1 at this time. At this time, an electrode plate guide 2 whose inside is mirror-finished is arranged between the separators 3 located at the rotating portion of the anode plate 4 so that the anode plate 4 can be smoothly inserted between the separators 3. . Then, while the anode plate 4 is being held, the upper and lower two points of the overlapping portion 3a of the separators 3 on both sides of the anode plate 4 are temporarily welded by ultrasonic waves. As shown in the enlarged view of FIG. 3, the electrode plate guide is provided with a cut 2a for temporary welding.

When the temporary welding is completed, the anode plate 4 is released from the clamp 1a, the index table 1 is rotated by 90 °, and the separator 3 is moved by a constant distance by the feeder. At this time, since the anode plate 4 is fixed at a total of four points on each of the upper and lower two points, there is no displacement between the separators 3. Thus, the separator 3 containing the anode plate 4 at regular intervals
Is sent to the next step, and in the next step, the entire overlapping portion 3a of the separator 3 is ultrasonically welded, the center of the welded portion is cut, and one anode plate in each bag-shaped separator is manufactured.

[0010]

Since the present invention is configured as described above, it has the following effects. (1) Since the electrode plate does not shift on the separator,
The separator is not damaged. (2) The electrode plate is not displaced during the movement from the electrode plate inserting step to the separator welding step.
