DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode group transport holder used in a manufacturing process of a lead storage battery.

[0002]

2. Description of the Related Art FIG. 5 shows the structure of a conventional electrode group transport holder. The transfer holder 1 has a number of holders 2 corresponding to the number of electrode plates to be inserted into the battery case of the storage battery, for example, six holders 2, and the electrode plates are inserted into the respective holders 2. It is supposed to be.

[0003] The holder portion 2 is composed of a plurality of guide side plates 3 arranged in parallel, and a guide bottom plate 4 attached to the lower surface of these guide side plates 3, and is formed in a gutter shape having a U-shaped cross section whose upper surface and both end surfaces are open. ing.

[0006] As shown in FIG. 6, an electrode plate group A in which a plurality of positive electrode plates and negative electrode plates are laminated with a separator interposed therebetween is clamped by a clamp device B and inserted into each holder 2 from above. Then, after this insertion, the clamp device B is removed. Each electrode plate group A is placed on the guide bottom plate 4 in a sideways posture with its ears turned sideways.

Each electrode plate group A inserted in each holder portion 2
Are pushed out of the holder portion 2 while being guided by the pusher 5 through the guide side plate 3 and the guide bottom plate 4, are aligned in the grouping process portion, and then are conveyed to the welding process process portion. The ears of each electrode plate group A are subjected to a treatment such as brushing or flux application. After this process, the same polarity ears of each electrode plate group A are welded to each other by a COS method or the like to form a strap connecting the same polarity ears to each other. Further, each electrode plate group A is transported to the battery assembling process section, where it is inserted into the battery case of the storage battery.

[0006]

Since the electrode plate group A is formed by laminating a positive electrode plate and a negative electrode plate via a flexible separator, when the electrode plate group A is clamped by the clamp device B, In this case, the width of the thickness of the electrode plate group A is such that the lower portion that is not clamped is wider than the upper portion clamped by the clamp device B.

The width of each holder portion 2 of the transfer holder 1 is regulated to a constant width. Therefore, when the electrode plate group A is clamped and inserted into the holder portion 2 by the clamp device B, the lower portion thereof is fixed. If the thickness on the side is widened, the electrode plate in the widened portion comes into contact with the guide side plate 3 and is deformed or damaged. The electrode plate group A has various thicknesses depending on the product type. In particular, in the electrode plate group A having a large thickness, the expanded portion on the lower side more easily comes into contact with the guide side plate 3 of the holder portion 2 and is deformed. Or be damaged.

Further, in the conventional transport holder 1, the pitch width between the parallel arrangements of the holder portions 2 is also restricted to be narrow and is narrow, and therefore, when inserting the electrode plate group A into each holder 2, The work is also troublesome and causes a decrease in efficiency.

The present invention has been made in view of such a point, and an object of the present invention is to hold the electrode group by a clamping device and insert the electrode group into each holder portion. An object of the present invention is to provide an electrode group transport holder capable of easily and efficiently inserting and storing an electrode group in each holder without causing deformation or damage.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a cross section in which the upper surface and both end surfaces are opened by a pair of guide side plates and a guide bottom plate provided between the lower portions of the guide side plates. A plurality of holder portions each having a U-shaped gutter shape are provided.In the electrode plate group transfer holder, in which the electrode plate groups clamped by the clamp devices are inserted and accommodated in these holder portions, the guide bottom plate of each holder portion is provided. When the electrode plate group is inserted into the holder section, the gap width between the guide side plates on both sides and the pitch width between the parallel arrangement of the holder sections are configured to be respectively expandable and contractible. The gap width between the guide side plates and the pitch width between the parallel arrangements of the holder portions are enlarged, and after the electrode plate group is inserted, the gap width between the guide side plates of the respective holder portions and the pitch width between the parallel arrangement of the holder portions are reduced. It is obtained so as to be reduced, respectively. The invention according to claim 2 is characterized in that the guide bottom plate of each holder portion is divided along a non-linear dividing line.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the transfer holder 11 according to the present invention has a plurality of, for example, six support tables 12 arranged in parallel with each other,
A holder 13 is provided on each of the support tables 12.

Each support 12 is connected via a guide shaft 14, and one support 12 disposed at the end is fixed to the guide shaft 14, and the remaining five supports 12 are connected to the guide shaft 14. It is slidably supported along. Then, a slidable support base 12 is driven by a driving mechanism 15 such as an air cylinder so as to move along the guide shaft 14, and by this drive, each holder unit 1 is moved.
The pitch width P between the three parallel arrangements is enlarged or reduced.

Each of the holder portions 13 has a pair of guide side plates 18 opposed to each other and a guide bottom plate 19 provided between the lower portions of the guide side plates 18 so as to form a gutter shape having a U-shaped cross section whose upper surface and both end surfaces are open. Have been. The guide bottom plate 19 is divided into right and left by a dividing line 20 along the center line in the longitudinal direction, and the dividing divides each holder portion 13 into a pair of half members 13a and 13b that can move in the width direction. ing.

Half members 13a and 13b of each holder 13
Are slidably supported on the support base 12 and move in directions in which they are brought into contact with and separated from each other by driving by a driving mechanism 21 such as an air cylinder, and the distance between the pair of guide side plates 18 opposed to each other by this movement. H is scaled.

FIG. 1A shows a state in which the pitch width P between the holders 13 arranged in parallel and the interval H between the guide side plates 18 of the holders 13 are enlarged, and FIG. Pitch width P between rows and interval width H between guide side plates 18
Are reduced to prescribed widths.

[0016] Dividing line 2 in which the guide bottom plate 19 is divided right and left
0 has a non-linear shape, for example, a wave shape as shown in FIG. 2, and the edge of one waveform and the edge of the other waveform divided by the dividing line 20 are in mesh with each other. In addition, 22 shown in FIG. 1 is a pusher for pushing out an electrode plate group.

When the electrode plate group A is inserted into each of the holders 13, the drive mechanism 15 increases the pitch P between the parallel arrangements of the holders 13 as shown in FIG. The guide side plate 18 in each holder portion 13 by the mechanism 21
The interval H between them is increased.

When the width of the gap between the guide side plates 18 is increased, the guide bottom plate 19 is inserted in order to prevent some of the electrode plates and the separators of the electrode plate group A to be inserted into the holder portion 13 from falling down. It is needless to say that the distance between the edge of one waveform and the edge of the other waveform of the dividing line 20 is set to be smaller than the difference between the distance between the concave portion of the waveform and the other convex portion.

In this state, as shown in FIGS. 3 and 4, the electrode group A is clamped by the clamp device B, and the electrode group A is positioned above one corresponding holder 13 and lowered. Insertion into the holder 13. When the electrode plate group A is inserted to a specified position in the holder portion 13, the drive mechanism 21 sets the interval width H between the guide side plates 18 of the holder portion 13 to the specified width as shown in FIG. Then, the clamp device B is removed from the electrode plate group A and raised.

In this manner, the electrode plate group A is inserted into each of the holder portions 13, and after this insertion, the drive mechanism 15 reduces the pitch width P of each of the holder portions 13 to a specified width. As described above, when the electrode plate group A is inserted into the holder portion 13, the interval width H between the guide side plates 18 of each holder portion 13 is increased, and therefore, the electrode plate group A is clamped by the clamp device B.
Even in the case of the electrode group A whose lower side is widened, the expanded part can be smoothly inserted without contacting the guide side plate 18, so that deformation and damage of the electrode group A can be reliably prevented. can do.

At this time, the parallel pitch width P of the holders 13 is also increased, and a sufficient space is provided between the adjacent holders 13, so that the electrode plate group A can be more smoothly moved. It can be inserted into the holder 13.

The electrode group A inserted into the holder 13 is placed on the guide bottom plate 19 of the holder 13. At this time, since the one half member 13a and the other half member 13b of the holder portion 13 are moving in a direction away from each other, a gap is formed in the divided portion of the guide bottom plate 19.
However, the dividing line 20 of the guide bottom plate 19 is in a wavy shape, and the convex portion and the concave portion are in mesh with each other. Therefore, even if the electrode plate group A is placed on The electrode plate of the electrode plate group A and the separator do not enter the gap. Therefore, even after this, even if the half members 13a and 13b move in the direction approaching each other and the gap of the divided portion of the guide bottom plate 19 is closed, there is no inconvenience such that the electrode plate or the separator of the electrode plate group A is sandwiched. This also allows the half members 13a and 13b to move smoothly.

The actual dimensional relationship is as follows. For example, the natural thickness of the electrode group A of a lead-acid battery of type 65D31 is 49 mm, and when the electrode group A is clamped by the clamp device B, the thickness of the clamped portion is increased. Compresses to 41 mm, the thickness of the lower part of which expands to 54 mm. Model 115D
31 has a natural thickness of 53 mm in the electrode group A. When the electrode group A is clamped by the clamp device B, the thickness of the clamped portion is compressed to 51 mm, and the thickness of the lower portion is 6 mm.
Spread to 0mm.

When handling such an electrode plate group A, for example, the maximum width when the interval width H of the guide side plates 18 of the holder portion 13 is enlarged is set to 64 mm, and the minimum width when reduced is set to about 54 mm. After the electrode groups A are inserted into the holders 13 of the transport holder 11 in this manner, the electrode groups A are guided by the pushers 22 via the guide side plates 18 and the guide bottom plates 19 while the holders are being held. Push it out of the part 13. Then, the electrode group A is aligned in a group aligning process section, and thereafter, is conveyed to a welding processing step section. In this processing step section, a process such as brushing or flux application is performed on ears of each electrode group A. After this process, the same polarity ears of each electrode plate group A are welded to each other by a COS method or the like, thereby forming a strap connecting the same polarity ears to each other.
Further, each electrode plate group A is transported to the battery assembling process section, where each electrode plate group A is inserted into the battery case of the storage battery. In the above-described embodiment, the dividing line 20 for dividing the guide bottom plate 19 to the left and right has a wavy shape. However, the present invention is not limited to this, and may be a non-linear shape such as a sawtooth shape or an uneven shape.

[0025]

As described above, according to the present invention,
The interval width between the guide side plates on both sides of each holder portion, and the pitch width between the parallel arrangement of the holders are configured to be respectively expandable and contractable, and when the electrode plate group is inserted into the holder portion, the interval width between the guide side plates of each holder portion, And since the pitch width between the parallel arrangement of each holder part is respectively enlarged, since the interval width of the guide side plate of each holder part after insertion of the electrode group, and the pitch width between the parallel arrangement of each holder part are reduced, When the electrode group is clamped by the clamp device and inserted into each holder, the electrode group can be easily and efficiently inserted and accommodated in each holder without causing deformation or damage of the electrode group. it can.
