[Problem to be solved by the invention]

In the arrangement of the mold groups of the conventional molding device described above, when assembling the six electrode plate group rows after welding into the cell chamber of the battery case, as described above, the electrode plate groups located every other The extraction work is inefficient because it has to be done in two parts. However, when assembling the taken-out electrode plate group into a monoblock battery case, in order to individually invert the electrode plate groups constituting the electrode plate group as described above, for example, an assembling device shown in FIG. 11 is used. Use the gripper G, and the respective gripper H
, H, H are a group of three electrode plates 82, 84.
In order to maintain the interval for reversing between the 86 plates, it is necessary to slide them along the horizontal support rod in the direction shown by the arrow to widen the mutual interval, and then invert each individual plate group. Therefore, there was an inconvenience that a large space S was required for the inversion as shown in the figure, and as a whole, the installation work was tedious and required a considerable amount of time. [Means for Solving the Problems] The present invention provides a C for lead-acid battery which eliminates one of the conventional disadvantages.
The present invention provides an OS type molding device, a method for assembling an electrode plate group array into a battery case, and an assembling device used in the method. That is, the CoS molding device for lead-acid batteries of the present invention has a mold base having:
A row of molds for welding an anode ear group and a row of molds for welding a cathode ear group on the other side are arranged parallel to each other on one side, and each mold for welding an anode ear group and each mold for welding a cathode ear group facing each other on both sides thereof. and lead molds arranged opposite each other to form a plurality of pairs of molds for casting anode straps and cathode straps for welding the downwardly facing anode and cathode ears on both sides of each electrode plate group, respectively. In a COS type molding device for a storage battery, among the array of mold pairs, the shape of each of the plurality of pairs of molds located sequentially from one end of the array is adjusted to fit all the cells separated by the partition walls of a predetermined monoblock battery case. Molds suitable for casting anode straps and cathode straps for welding, respectively, the anode and cathode ears of each plate group to be accommodated in the cell chamber located every other cell from one end of the chamber. The anode of each electrode plate group is formed into a shape, and the remaining plurality of sequentially positioned mold pairs are collectively inverted and housed in the remaining cell chambers located in every other cell of the battery case. These are formed into mold shapes suitable for casting the anode strap and cathode strap to which the ear group and cathode ear group are respectively welded. Furthermore, the present invention provides a method for assembling a welded array of electrode plates into a monoblock battery case by means of the casting apparatus of the present invention, by lifting them from the molding apparatus and removing their respective negative and anode straps. After making the electrode plate group face upward, the electrode plate group row is divided into one electrode plate group arranged sequentially from one end and the remaining electrode plate group and lifted at the same time, and then the former electrode group While each electrode plate group constituting the group is housed in every other cell chamber from one end of all the cell chambers of the monoblock battery case without being reversed,
The present invention is characterized in that after the latter electrode plate group is inverted all at once, each of the electrode plate groups is accommodated in every other remaining cell chamber of the battery case.

Furthermore, the present invention does not include the cathode strap and anode strap cast by the above-mentioned casting apparatus, that is, the assembly in which the welded electrode plate group rows are respectively inserted into the cell chambers at predetermined positions of the monoblock battery case. It provides a device for incorporating a group of electrode plates to carry out the method, and is a suspension support that can slide freely along a common horizontal base that is connected to a common horizontal base that can be moved up and down by a lifting device such as a piston cylinder. A pair of rods are arranged on the left and right, and one of the suspension support rods is configured to be rotatable,
A horizontal support rod is provided at the lower end of both suspension support rods, and a plurality of electrode plate group grippers are arranged at predetermined intervals on each horizontal support rod. [Function] The above book. Molten lead is poured into a pair of molds of the molding device of the invention, and the tips of the anode and cathode ears of the electrode plate row are inserted into the pair of molds with their respective anode and cathode ears facing downward, and the mold is cast. Weld the anode and cathode ears of each plate group using the anode and cathode straps. Thus, after welding is completed, it is pulled up and placed with the negative and anode straps facing upward. In this way, one electrode plate group welded by a plurality of mold pairs sequentially located from one end of the mold pair row is suitable for being directly inserted into the cell chambers located every other cell from one end of the battery case. The other electrode plate groups welded with the remaining plurality of mold pairs are each suitable for insertion into the remaining cell chamber of the battery case after the batch reversal. It becomes possible to simultaneously grasp and suspend the first electrode plate group and the second electrode plate group. In this case, a COS molding device for lead-acid batteries consisting of six cells is generally preferred;
A pair of molds up to 3M in the second and third positions are placed every other pair from one end of a predetermined monoblock battery case, that is, three molds are placed in the first, third, and fifth positions. The anode and cathode ears of each electrode plate group accommodated in the cell chambers are respectively formed into a pair of molds suitable for casting an anode strap and a cathode strap, and the remaining fourth and cathode 5
The three pairs of molds located at the 2nd, 4th, and 6th positions are inserted into the remaining 3 cell chambers at the 2nd, 4th, and 6th positions at once. A mold device is constructed in which the anode strap and cathode strap for welding the anode and cathode ears of the plate group are respectively formed into a pair of molds suitable for casting. As a result, welded electrode plates suitable for insertion into the first, third, and fifth cell chambers of the battery case are obtained by the mold pairs located sequentially from one end, and the remaining three pairs The mold pairs lead to the second, fourth, and sixth cell chambers where the battery containers remain.
A welded electrode plate group array suitable for batch reversal insertion is obtained.

In this case, if the mold apparatus is equipped with a heating device that separately heats the mold row for anode lug welding on one side and the mold row for cathode lug welding on the other side, each mold is heated with appropriate lead. It is preferable to weld each ear group at the molten metal temperature. In addition, when the spacing between adjacent mold pairs in the mold pair row is made to correspond to, or correspond to, the spacing between every other cell chamber of the battery case, the resulting welded When a row of electrode plates is suspended by the assembly device and housed in every other cell chamber of the battery case, there is no need to particularly increase the spacing between each electrode plate, and the assembly work and device can be completed quickly. , it can be easily done. Furthermore, according to the method of assembling the welded electrode plate group rows in the above-mentioned arrangement taken out from the molding apparatus of the present invention into a battery case, one electrode plate group arranged sequentially from one end of the electrode plate group row. Grasp and suspend the group and the other remaining electrode plate groups at the same time,
Each electrode plate group of one electrode plate group is inserted into every other cell chamber from one end of the battery case, while the other electrode plate group is group-inverted and then inserted into each cell chamber. Since the board group is inserted into the cell chamber where the battery case remains, the assembly work is shortened compared to the conventional assembly method in which the battery is lifted up in two steps, and the space required can be significantly reduced.
In this case, it is generally preferable to apply it to a COS type molding device for a lead-acid battery consisting of 6 cells, and when the electrode plate group row obtained from this is assembled into a battery case consisting of 6 cell chambers, the above-mentioned assembly method is used. A lead-acid battery assembly consisting of 6 cells can be easily and quickly obtained. Further, according to the above-mentioned assembly device of the present invention, each of the electrode plate group rows welded by the present method is attached to each of the electrode plate group grippers disposed on the respective horizontal support rods of the left and right suspension support rods. After gripping the two electrode plate group groups, each of the electrode plate groups gripped by the electrode plate group gripping tool of either the left or right suspension support rod is placed into a cell of a battery case. The electrode plate groups inserted into the cell chambers located every other cell room from one end of the chamber and gripped by the electrode plate group gripping tool of the other suspension support rod are removed by rotating the suspension support rod. After the electrode plates are assembled and inverted, they are inserted into every other remaining cell chamber of the battery case to form a lead-acid battery assembly. This speeds up the installation process and reduces the reversal space. In this case, to construct a lead-acid battery assembly consisting of 6 cells, three groups of electrode plates welded by this method are suspended from the left and right suspension support rods, taken out from the molding device, and then A 6-cell lead-acid battery can be obtained by inserting it into the 6 cell chambers of the tank using the method described above. In addition, when the mutual spacing of all the electrode plate group gripping tools of the built-in device is arranged in advance at intervals corresponding to every other cell chamber of the battery case, It is convenient because it allows quick lifting of each electrode plate group and insertion of the battery case into the cell chamber.

A lead-acid battery assembly 6 is obtained from the six cells shown. Therefore, the mold apparatus of the present invention is configured such that the distance between each mold pair in the mold pair row is the same as that of every other cell chamber of the battery case, as shown in the first diagram. is preferred, so that when the welded plate group rows are lifted from the mold pair rows and placed upwardly as shown in the second figure, the plate group rows lined up at intervals of every other cell chamber. is obtained. Then,
The left and right electrode plate group groups 81, 83, 85 and 86, B4, 82, which are respectively suspended by a pair of left and right suspension support rods 12a, 12b of the built-in device of the present invention shown in FIG. 13a and 13b in advance at intervals corresponding to every other cell chamber, so that the electrode plate group row shown in the second diagram can be immediately divided into two left and right electrode plate group groups. They can be hung separately and inserted into every other cell chamber 5, 5.5 of each battery case 4, making assembly work easier. As is clear from the above, in other words, the configuration of the above-mentioned mold apparatus of the present invention is as follows. It is characterized in that the shapes of the mold pairs for the first to sixth electrode plate groups are respectively formed as follows. That is, the shape of the first mold pair is formed as the shape of the first cell of the battery case 4. The shape of the second pair of molds is made to be suitable for welding the negative and anode ears housed in the chamber 5, and the shape of the second mold pair is changed to the shape of the second mold pair to fit the negative and anode ears housed in the third cell chamber 5 of the battery case 4. The shape of the third pair of molds is made to be suitable for welding each negative and anode ear group housed in the fifth cell chamber 5 of the battery case 4. , the shape of the fourth pair of molds is made to be suitable for welding the negative and anode ear group to be inverted and housed in the cell chamber 5 of the sixth place of the battery case 4, and the shape of the mold pair of fifth place is made is made into a shape suitable for being inverted and accommodated in the cell chamber 3 in the 6th position of the battery case 4, and the shape of the mold pair in the 6th position is made to be inverted and accommodated in the cell chamber 3 in the 6th position in the battery case 4. In this way, when a row of electrode plates with negative and anode ears welded respectively using a pair of molds is pulled up and placed upside down, , an array of electrode plate groups arranged in the order shown in the second figure is obtained.
Therefore, it is convenient that this row of electrode plates can be divided into two left and right electrode plate groups and suspended at the same time by the built-in device of the present invention, and the intervals between the suspended and supported electrode plate groups are adjusted as described above. Since a suitable interval is maintained so that the battery case 4 can be accommodated in every other cell chamber, the subsequent operation of inserting the battery case into the cell chamber can be carried out smoothly and quickly. The above is a detailed description of the COS type molding device for welding the plate lug group for a lead-acid battery consisting of six cells as an embodiment of the present invention, the method of assembling the welded plate group array obtained thereby into t1IF, and the assembling device. As described above, the present invention is not limited to this, but includes a COS molding device for welding electrode groups and ears for lead-acid batteries consisting of four or more cells, a method for assembling the electrode groups into a battery case, and the like. It goes without saying that the present invention is also applicable to built-in devices. Therefore, the general configuration of the molding apparatus of the present invention is as follows.

That is, a plurality of pairs of molds having shapes suitable for welding the positive and cathode lugs of a plurality of electrode plate groups suitable for being accommodated in every other cell chamber from the end of the battery case are sequentially arranged, A plurality of pairs of molds having a shape suitable for welding the positive and negative electrode plate lugs of a plurality of electrode plate groups suitable for inversion accommodation in the remaining cell chamber are sequentially arranged in the above mold pair as follows. The device is characterized in that the welded electrode plate group row is pulled up and placed upward, and then the electrode plate group row is lifted up by a pair of left and right suspension support rods of the built-in device of the present invention. Divide into two groups and lift them at the same time.One of the electrode plate groups is placed in the cell chamber at every other cell from the edge of the battery case without being turned over.The remaining electrode plate groups are grouped together. After the cells are inverted, they are housed in the remaining cell chambers, so that an arbitrary lead-acid battery assembly consisting of four or more cells can be obtained.

〔Effect of the invention〕

According to the present invention, the anode lug welding molds are lined up on one side of the mold base, the cathode lug welding molds are lined up on the other side, and the molds facing each other on both sides are arranged in a line on the mold base surface. In a COS type molding device configured with a pair of molds, the shape of a plurality of pairs of molds located sequentially from one end of the mold is housed in a plurality of cell chambers placed every other cell from one end of a monoblock battery container. The anode lug group and the cathode lug group of the electrode plate group are formed into shapes suitable for welding casting, and the remaining subsequent mold pairs are inverted into every other remaining cell chamber of the battery case. Since the anode ear group and the cathode ear group of the electrode plate group to be accommodated are formed into mold shapes suitable for welding and casting, the anode ear group and cathode ear group of the electrode plate group row are formed using the same molding device. When the welded electrode plate group rows obtained by welding are assembled into a battery case, they can be suspended simultaneously by the assembly device as two left and right electrode plate group groups, so that the welded electrode plate group rows obtained by the above-mentioned COS molding device can be suspended as two left and right electrode plate group groups at the same time. Compared to suspending every other welded electrode plate group as a group twice, this method has the effect of requiring only one lifting operation. Furthermore, the method of assembling the electrode plate group array into the battery case according to the present invention is to divide the electrode plate group array thus obtained into two groups, left and right, and to assemble the first electrode plate group group as it is. By placing each monoblock battery into every other cell chamber from one end of the container, and after inverting the second electrode plate group as a group, each of the monoblock batteries is housed in every other remaining cell chamber. In all the cell chambers of the battery case, the anode straps and cathode straps of the electrode plate groups on both sides of each partition wall are placed alternately on both sides from one end to the other, allowing for series connection. This has the effect that a lead-acid battery assembly in a good condition can be obtained, and as mentioned above, since the second electrode plate group is reversed for each group during the assembly process, the electrode plates are This has the effect that the space required for inversion is significantly smaller than if the individual plate groups of the group were inverted. Furthermore, an apparatus for carrying out the method of assembling a row of electrode plate groups into a monoblock battery case according to the present invention includes a pair of support rods for suspending electrode plate groups that are slidably provided on a vertically movable horizontal base rod. One of the support rods is rotatable, and a plurality of electrode plate group grippers are disposed on the support rods of each support rod, so that the electrode group taken out from the molding device of the present invention can be held between the right and left sides. A group of electrode plates that can be divided into the two groups and simultaneously gripped and suspended by the suspension support rods, and then gripped by a plurality of gripping tools arranged on the support horizontal rods of one of the suspension support rods. The respective electrode plate groups constituting the battery case are housed as they are in every other cell chamber of the battery case, and the other plate group is held by a gripper disposed on the support horizontal support rod of the other suspension support rod. When the electrode plate groups constituting the electrode plate group are collectively inverted for each group and then housed in the remaining cell chambers of the battery case, a lead-acid battery assembly that can be connected in series by cell-to-cell connection is obtained; In this case, since the other plate group is inverted all at once, it is possible to eliminate the work of sliding on the support horizontal rod, which is required to individually invert every other plate group taken out. Furthermore, in the molding device of the present invention, the distance between each mold pair in the mold pair row is set to every other one of the battery containers. While the cell chambers are arranged at intervals corresponding to the intervals between the cell chambers, the intervals between the suspension group gripping tools of the left and right suspension support rods of the built-in device of the present invention are set in advance so as to correspond to the intervals between every other cell in the battery case. When the electrode plates are arranged at intervals corresponding to the intervals between the chambers, the above-mentioned molding device produces a row of electrode plates in which welded electrode plates are lined up at intervals of every other cell chamber, Therefore, as described above, these electrode plate groups can be immediately grasped and suspended at the same time by the electrode plate group gripping tool of the arrayed assembly device, resulting in the effect of improving the efficiency of the assembly work. In addition, in the mold apparatus of the present invention, when separate heating devices are provided for the anode strap casting mold row and the cathode strap casting mold row, the molten metal temperature can be adjusted to a temperature suitable for each welding, and good welding can be achieved. This has the effect of providing a uniform array of electrode plates.
