Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method for assembling a storage battery.

(Prior art) Conventionally, the method of assembling a storage battery is to place a battery case containing battery elements in each cell chamber, the interior of which is partitioned by a partition wall, in an inverted state onto the fitting part of a lid that is placed upside down. A type in which the opening edges are fitted together with an adhesive to form a combined container is known.

(Problems to be Solved by the Invention) The conventional method of assembling a storage battery described above has a disadvantage in terms of work efficiency, as it is not possible to grasp and lift the battery case part of the combined container until the adhesive has hardened. It was hot. If the combined container is moved while the adhesive is not cured, it will slide on the stand without being lifted, resulting in inconveniences such as scratches on the outer surface of the lid.

(Means for Solving the Problems) The present invention provides a method for assembling a storage battery with the purpose of solving the above-mentioned disadvantages of the conventional storage battery assembly method and improving assembly work efficiency. At the same time, inject adhesive into the fitting part of the lid, and while holding the battery case with battery elements housed in each cell chamber, which is partitioned by a partition wall, upside down, insert the opening edge into the fitting part of the lid. In the method of assembling a storage battery, in which a battery case is formed by inserting the battery case into the container and joining the battery case and the lid using the adhesive to form a base container, the groove-like fitting part on the back of the lid or the open end of the battery case is inserted in advance. A plurality of pressing and fixing protrusions are provided scattered on one side of the part corresponding to the groove-like fitting part on the back side of the lid on the rim, and the part is placed upside down on the fitting part of the lid into which the adhesive is injected. When the opening edge of the battery case is inserted, the fitting state of the opening edge of the battery case to the fitting portion of the lid is fixed by pressing through the protrusion.

(Example) Next, an example of the present invention will be described with reference to the accompanying drawings. FIGS. 1 and 2 show an example of the implementation of the present invention, in which 1 represents a lid and 2 represents a battery case. The lid 1 is shown upside down, and its periphery 1a has a fitting portion 3a with an L-shaped cross section on which the periphery 2a of the battery case 2 is fitted.
46 housing-shaped exhaust pipes each having an exhaust hole in the center for the six cell chambers are arranged in two rows of three each, and two exhaust pipes are arranged in each row in the width direction. A groove-shaped fitting part 3b into which a partition wall 2b extending in the longitudinal direction at the center of the lid 1 fits between the two, and a groove-shaped fitting part 3b between each exhaust pipe 4 and both side edges of the peripheral edge 1a. portions 3c, 3c are formed. Furthermore, the periphery 1 of the lid 1
A concave space 5, 5, 5 for filling with adhesive is formed between the exhaust pipes 4, 4 arranged in the width direction and arranged in the length direction, and each concave part Partition walls 2c extending in the width direction and partitioning the inside of the battery case 2 are inserted into the center of the space 5 to partition the back space of the lid 1. The opening edge A of the battery case 2 is composed of a peripheral edge 2a, an edge of a partition wall 2b extending in the length direction that partitions the inside thereof, and an edge of three partition walls 2c extending in the width direction. In other words, the opening edge of the battery case 2 is not only the peripheral edge 2a of the peripheral side wall thereof, but also the peripheral edge 2a of the peripheral side wall thereof.
The interior is partitioned vertically and horizontally into six cell chambers 6, 6...
This is a general term that includes the edges of the partition walls 2b and 2c that form the partition. Therefore, battery elements are immovably housed in each cell chamber 6 in the battery case 2 in a conventional manner, and intercell connections are made beyond the upper edge of the partition wall to connect these six battery elements in series. Adjacent battery elements are connected via rods to form a battery case, but illustration of these elements is omitted for convenience of explanation of the present invention. In order to assemble the combined container, that is, the storage battery, by fitting and bonding the lid 1 and the battery case 2 together using an adhesive, conventionally, the lid 1 is turned over, and the recessed spaces 5, 5, 5 on the back side of the lid 1 are turned over. and its L-shaped fitting part 3
Inject adhesive 7 into a and groove-shaped fitting parts 3b and 3c,
After filling the recessed spaces 5, 5, and 5 with an adhesive filling layer 7 of an appropriate depth, the battery case 2 is
is inverted, and its opening edge A is its periphery 2a.
and fittingly placing the partition wall 2b in the corresponding L-shaped fitting part 3a and groove-shaped fitting parts 3b and 3c of the lid 1,
The partition walls 2c, 2c, 2c are respectively embedded in the adhesive layer 7 of the concave spaces 5, 5, 5, and left as they are for a long time, and after the adhesive has hardened, they are bonded into one piece. The combined container B was either lifted up and moved, or immediately slid on a table while the adhesive was not yet cured. In this case, waiting for the adhesive to harden before moving the cover is extremely inefficient, and moving the cover by sliding it on the table causes inconveniences such as scratches and other damage to the outer surface of the cover. In the drawings, reference numeral 8 indicates each exhaust port provided at one end of the lid 1 which is connected to each of two rows of exhaust pipes 4 via a duct.

In view of the above, the present invention provides, after combining the lid and the battery case,
The device is designed so that the battery case can be immediately grasped, lifted, and moved.
On the battery case 2 side, a plurality of pressing and fixing protrusions 9 are provided in spots on the opening edge A of the back surface of the lid corresponding to the groove-shaped fitting parts 3c, 3c, and the battery case 2 is Lid 1
When the battery case 2 is fitted and placed upside down as described above, the opening edge of the battery case 2 is bonded to the fitting part of the lid 1 via the pressing and fixing protrusion 9, and as a result, the battery case 2 is immediately closed. The combined container B can be lifted and transferred by grasping its battery case part from both sides.

To explain this in detail, in the embodiment described above, the pressing and fixing protrusions 9 are fitted onto the lid 1 on both sides of the opening edge A of the battery case 2, for example, on both sides of the periphery 2a in the longitudinal direction. When placed, the groove-like fitting portions 3c, 3 between the opposite side edges of the peripheral edge 1a of the lid 1 and the opposing exhaust pipes 4, 4.
At the position corresponding to c, when fitted, the groove-like fitting portions 3c, 3c are firmly press-fitted, and the tips of the protrusions 9, 9 are firmly pressed and locked to the corresponding side surfaces of the exhaust pipes 4. It was arranged so that Then,
As is clear from the second diagram, when the battery case 2 having such a protrusion 8 is press-fitted to the back surface of the lid 1,
These protrusions 9, 9 are connected to the groove-shaped fitting portion 3 of the lid 1.
3c and 3c, the battery case 2 is firmly connected to the lid 1 due to the pressing intervention of the protrusion 9, and the combined container B and the inverted battery case part of the battery are held on both sides thereof. Even if the battery case 2 is grasped and lifted from the surface, the opening edge A of the battery case 2 does not come off from the fitting part of the lid 1 and can be lifted together with the lid 1 as a combined container. Advantageously, the adhesive 7 filled in the joints and recessed spaces can be immediately lifted up and moved while it is not cured, which facilitates and speeds up battery manufacturing operations.

As shown in the figure, the protrusion 9 of this embodiment has an inclined surface that tapers toward its tip; by forming a tapered surface, it is possible to press the protrusion 9 into the corresponding groove-shaped fitting portion 3c of the lid 1. I tried to make it easier. The press-fixing protrusion 9 of the present invention can be provided on the lid 1 side instead of being provided on the opening edge A of the battery case 2.

FIG. 3 and FIG. 4 show an embodiment in which it is provided on the lid 1 side. That is, one pair of clamping and pressing fixing protrusions 9, 9 pairs each to protrude into the groove-like fitting parts 3b, 3b, 3b into which the central partition wall 2b of the battery case 2 fits,
An example is shown in which each of the opposing exhaust pipes 4, 4 is provided protruding from the opposing side surface. Thus, when the inverted battery case 2 is fitted and placed on the lid 1, the central partition wall 2b of the battery case 2
The edges of the groove-like fitting portions 3b are strongly pressed and clamped on both sides by pairs of opposing protrusions 9, 9,
Thereby, the fitted state of the battery case 2 to the lid 1 can be fixedly maintained.

FIG. 5 shows a modification thereof, in which instead of providing the protrusions 9, 9 in the groove-like fitting part 3b on the back surface of the lid 1, the protrusions 9, 9 are placed above the upper surface of the opposing exhaust pipes 4, 4, respectively.
A pair of pressing and fixing protrusions 9, 9 are provided on both sides of the central partition wall 3b, each of which presses and clamps the central partition wall 3b protruding from the body.
