Description

  The present invention relates to a battery plate separation / alignment apparatus and a separation / alignment method for separating a plate block in which electrode plates such as a plurality of stacked battery plates are bonded to each other.

A laminated lead-acid battery constitutes an electrode group by, for example, alternately laminating positive and negative plates filled with an active material on a cast lattice substrate via a separator.
In the electrode plate manufacturing process, a plurality of electrode plates coated with an active material paste are stacked on a lattice substrate, and the stacked electrode plates are brought into an aging furnace and aged. After this aging, since the electrode plates taken out from the aging furnace are carried out in a state where the laminated plates are bonded together, the bonded electrode plates are separated from each other and sent to the next stacking step. .

  The work of separating the electrode plates bonded to each other one by one has been mainly performed manually, but due to the movement of mechanization, several separation devices have been proposed. For example, in Patent Document 1, as shown in FIGS. 6 and 7, an electrode plate block 62 made up of a plurality of stacked and bonded electrode plates is set on an electrode plate separating jig 64 and bonded to each other. A technique for separating the two is disclosed. As shown in FIGS. 6 and 7, the electrode plate separating jig 64 includes two support plates 66 and 66 erected on a pedestal 65 so as to be swingable face to face with a gap therebetween. Each of the plates 66 and 66 is a rectangular metal plate having a size substantially the same as that of the electrode plate 63, and a lower end portion of each of the plates 66 and 66 is attached to the pedestal 65 via a hinge 67 so that they can swing in the same direction. A connecting rod 68 is swingably attached to the upper ends of the support plates 66 and 66, and the support plates 66 and 66 are configured to swing in conjunction with each other while maintaining a parallel state.

The electrode plate block 62 is set on the electrode plate separating jig 64, and the support plates 66 and 66 are pushed left and right to swing. By this operation, for example, as shown in FIG. 7, when the left support plate 66 pushes the upper part of the electrode plate block 62 in the right direction, the electrode plate block 62 falls to the right side, and the space between the electrode plates 63 is little by little. It is a concept of tilting in a state shifted in the vertical direction and separating each electrode plate 63.

  In the conventional method of separating the electrode plate blocks, the electrode plates can be separated from each other. However, since some of them are still stuck together, improvement is desired. In addition, since there is no means to suppress the electrode plate block, the separated electrode plates are not aligned vertically and horizontally, and a work process for arranging and stacking a plurality of electrode plates again is required, which increases the number of work steps. The problem occurs.

  The present invention has been made in order to cope with such a situation, and separates an electrode plate block in which a plurality of electrode plates are bonded to each other in an aligned state, so that the block can be conveyed to a subsequent process as it is. An object of the present invention is to provide a battery electrode plate separation / alignment apparatus and method for separating and aligning the same.

The separation and alignment apparatus for battery electrode plates of the present invention includes a holder for holding electrode plate blocks that are stacked and bonded to each other, a pressurizing tool that applies pressure to the electrode plate blocks held by the holder, and the holder A separator for a battery electrode plate, which is arranged on the left and right sides of the open plate and applies a pressing force to the electrode plate held by the holder from the left and right, and the holder includes left and right side walls. When holding the electrode plate block, having a holding surface with a width slightly larger than the thickness of the electrode plate block, the pressurizing tool is disposed above the holder, The pressurizing tool is made of a material that is in contact with the electrode plate block and does not damage the electrode plate block when pressure is applied. The electrode plate has a pressurizing plate and is held by the holder. From the top of the electrode plate block to the electrode plate block with the pressure tool The pressure tool is swung while applying force, the adhesion between the electrode plates is peeled off, and a plurality of electrode plates separated one by one in the holder are subjected to pressing force from the left and right by the alignment tool. This is a separation and alignment device that aligns a plurality of electrode plates that are uneven in the left and right directions.

The battery plate separation / alignment method of the present invention is a battery electrode separation / alignment method in which a plurality of electrode plates are laminated and peeled one by one from a plate block that is adhered to each other and aligned. The electrode plate block is attached to a holder configured in a bowl shape composed of left and right side walls and a holding surface so that the thickness of the electrode block in the stacking direction is slightly thinner than the width of the bottom surface of the holder. The electrode plate block is selected and held, and is made of a material that does not damage the electrode plate block when pressure is applied to the electrode block from above the electrode block held by the holder. Applying pressure with a pressure tool equipped with a pressure plate, and oscillating the pressure tool to peel off the adhesion between the electrode plates, a plurality of electrode plates separated one by one in the holder. Left and right of the holder against the plurality of electrode plates that are uneven in the left and right direction. This is a method for separating and aligning battery electrode plates , in which the electrode plates are aligned by applying a pressing force from the left and right with the alignment tool provided on the battery.

  According to the present invention, the electrode plate block is held by the holding tool, and the rocking force is applied to the electrode plate block in a state where the electrode plate block is pressurized from above. A plurality of electrode plates can be sent to the next process in a stacked state in which the electrodes are aligned in the front, rear, left, and right directions, the number of steps for stacking again in the next process can be reduced, and the efficiency in the next process can be improved.

For example, an electrode plate for a storage battery is prepared by filling a grid substrate made of lead or a lead alloy with a paste-like active material to form an electrode plate, laminating a plurality of electrode plates filled with the active material, and carrying them to an aging furnace for aging. . In this aging process, the electrodes are bonded together, and are carried out as a lump of electrode plates (electrode plate block). Therefore, in order to send out the electrode plate block to be carried out to the next process, it is necessary to separate the electrode plates one by one.
The present invention relates to an apparatus and method for separating and aligning the electrode plate blocks one by one, and an embodiment of the present invention will be described in detail below with reference to the drawings.
1 to 5 show a first embodiment of the present invention. FIG. 1 is a front view of a separating and aligning apparatus 100 in a state where an aligner is removed, and FIG. 2 is a cross-sectional view taken along line AA in FIG. 3 and 4 are explanatory diagrams for explaining the operation of the separation and alignment apparatus 100, and FIG. 5 is an explanatory diagram for explaining the alignment tool and its operation.

In the figure, 1 is an electrode plate block, and the electrode plate block 1 is held by a holder 2. The holder 2 is configured in a bowl shape that is open in the left and right and upper directions, that is, in a bowl shape including left and right side walls 21 and 21 and a holding surface 23 (bottom surface 23). When the block 1 is held, the holding surface 23 having a width slightly larger than the thickness of the electrode plate block 1 is provided.
The electrode plate block 1 held by the holder 2 has a plurality of electrode plates 11 stacked as described above, and the electrode plates 11 and 11 are bonded to each other during aging in the aging furnace in the previous step. ing.
As shown in FIG. 2, the electrode plate block 1 in which the electrode plate 11 is bonded is attached to the holder 2 so that the ear 12 of the electrode plate 11 is located on the left side and the foot 13 is located on the right side. Retained. That is, the side surface of the electrode plate 11 is vertically held and is held by the holder 2.

A pressurizing tool 3 that applies pressure to the electrode plate block 1 held by the holder 2 is disposed above the holder 2. The pressure tool 3 includes a pressure plate 31, a cylinder 32 that moves the pressure plate 31 up and down to apply pressure to the electrode plate block 1, and a swing device 33 that swings (reciprocates) the pressure plate 31. Has been.
The pressure plate 31 is made of, for example, hard rubber, and is made of a material that is in contact with the electrode plate 11 and does not damage the electrode plate 11 when pressure is applied.
The cylinder 32 moves the pressure plate 31 up and down so that the holder 2 holding the electrode plate block 1 can be smoothly inserted and removed, and the pressure plate 31 is brought into contact with the electrode plate block 1 and the electrode plate block. 1 is pressurized with a predetermined pressure.
The oscillating device 33 uses, for example, an eccentric motor, and is configured to oscillate the pressure plate 31 (for example, reciprocate in the stacking direction of the electrode plate block 1).

Next, a process of separating each electrode plate 11 from the electrode plate block 1 to which a plurality of electrode plates 11 are bonded will be described.
The electrode plate block 1 taken out from the aging furnace is held by the holder 2. At this time, as shown in FIG. 2, the holder 2 is positioned such that the ear 12 of the electrode plate 11 is positioned on the left side and the foot 13 is positioned on the right side, that is, the side surface of the electrode plate 11 is positioned vertically. Hold on. Further, the number of the electrode plates 11 is selected so that the thickness of the electrode plate block 1 in the stacking direction is slightly smaller than the width of the bottom surface 23 of the holder 2.

First, the holder 2 holding the electrode plate block 1 is incorporated into the separation / alignment apparatus 100. That is, it is set under the pressurizing tool 3.
When the holder 2 is set, the cylinder 32 of the pressurizing tool 3 is operated to lower the pressurizing plate 31, and the pressurizing plate 31 is brought into contact with the electrode plate block 1 and further lowered as shown in FIG. A predetermined pressure is applied to the electrode plate block 1. Here, the predetermined pressure means that the electrode plate 11 is not deformed, and the pressure plate 31 and the electrode plate block 1 are moved with respect to the movement of the pressure plate 31 for peeling off the adhesion of the electrode plate block 1 described later. The pressure is such that no slip occurs.
In a state where a predetermined pressure is applied to the electrode plate block 1 by the pressurizing plate 31, the swinging (reciprocating) device 33 is operated to swing the pressurizing plate 31 (reciprocating). The reciprocating movement is performed in the direction in which the electrode plates 11 are stacked (in the direction of the arrow in FIG. 4) and in the opposite direction.

  As the pressure plate 31 moves, the upper part of the electrode plate block 1 is forcibly moved in the thickness direction as shown in FIG. However, since the movement of the lower end portion of the electrode plate block 1 (the side held by the holder 2) is restricted by the side surface 21 of the holder 2, each electrode plate 11 swings around the lower end portion as a fulcrum. Each electrode plate 11 is moved slightly and uniformly in the thickness direction, and is separated from each electrode plate 11 because it is moved against the adhesive force bonding the electrode plates. When the swing operation is insufficient at one time, it can be separated from each other by reciprocating a plurality of times. In this way, the respective electrode plates 11 are surely separated from each other, and there is no possibility of being damaged by receiving an excessive force.

  Since the separation work in the separation / alignment apparatus 100 is performed in a state in which the electrode plate block 1 is pressed by the pressure plate 31, the plurality of electrode plates 11 separated one by one are not aligned vertically, although there are some irregularities on the left and right. There is no.

FIG. 5 is an explanatory diagram for explaining the alignment tool 5 for tearing a plurality of electrode plates that are irregular in the above and the operation thereof.
As described above, when the electrode plate block 1 is separated into the electrode plates 11 and the electrode plate block 1 is separated into the electrode plates 11 within the holder 2, unevenness may occur in the left and right directions. This is because the electrode plates 11 are not aligned in the stacking process or the transport process in the previous process, or because the electrodes are displaced from each other due to the swing in the separation process. The alignment tool 5 is provided on the left and right of the holder 2 that separates the electrode plate block 1.

As shown in FIG. 5, the aligning tool 5 has cylinders 51 and 52 arranged on the left side and cylinders 53 and 54 arranged on the right side. A first alignment operation is performed by operating the left upper cylinder 51 and the right lower cylinder 54 on the electrode plates 11 separated in the separation step to push the electrode plate 11 from the left and right. Next, the cylinders 51 and 54 are retracted, the lower left cylinder 52 and the upper right cylinder 53 are advanced, the electrode plate 11 is pushed, and the second alignment operation is performed. By this operation, the electrode plates 11 are almost aligned, but if necessary, this operation is repeated a plurality of times so that the electrode plates 11 are stacked in a properly aligned state and can be transported to the next process.
In the above embodiment, four cylinders are arranged. However, one cylinder may be arranged on each side depending on the size of the electrode plate.

  In the embodiment described above, the embodiment in which the holder 2 is used as a conveying tool has been described. However, the electrode plate block 1 is set in a state where the holder 2 is set in the separating and aligning apparatus and is conveyed sideways from the previous process to, for example, a belt conveyor. Is received by the holder 2 of the separation / alignment apparatus so that the side surface of the electrode plate 11 is positioned vertically as described above, and after separation / alignment, it is taken out from the holder 2 and transferred to a transport tool (for example, a belt conveyor) for the next process. You may make it do.

  Moreover, in the said embodiment, although the electrode plate 11 of the lead storage battery was demonstrated, if it is a laminated type battery which laminates | stacks the electrode plate 11 which carry | supported the active material, it will be similarly applied to the electrode plate of another kind of battery. Of course, it can be implemented.

  As is clear from the above description, according to the separation and alignment apparatus and separation and alignment method of the electrode plate of the present invention, the electrode plate is held by the holding tool 2 and the pressure plate presses the upper side of the electrode plate block. Therefore, each electrode plate can be separated evenly by a small amount evenly, and the electrode plate is not damaged. In addition, the electrode plate 11 can be neatly arranged by arranging the alignment tool, and the electrode plate 11 is beautifully coupled with pressing the upper side of the electrode plate block with the pressure plate to restrict the movement of the electrode plate. Can be separated in an aligned state.
