Abstract

PURPOSE:To easily manufacture two kinds of batteries of the same sizes but having differently shaped external terminals, so as to reduce the number of working manhours by setting the folding position of a terminal for drawing battery power output above a middle lid, or above an upper lid for covering the middle lid. CONSTITUTION:The folding position of a terminal, one end of which is connected to the pole column of a plate group stored in an electric jar 3, and the other end of which penetrated the end part of a middle lid 4 for covering the electric jar 3 and projects above the lid 4, is set on the upper surface of the lid 4, or above an upper lid 2 for covering the lid 4. In the case of a lead- drawing type, the lid 4 and the electric jar 3 are fixed together by an adhesive injected into the rear surface of the lid 4, while terminals 1, 1' which penetrate a through hole and project above are folded inward along the upper surface of the lid 4 at an outlet part (a) of the through hole. In the case of a tub terminal type, after the lid 2 is fitted on the lid 4, the terminals 1, 1' are folded inward on the lid 2. Two kinds of batteries of the same sizes but having differently formed external terminals can thus be easily manufactured, while the number of working manhour at the time of assembling a battery can be reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a sealed lead acid battery, and more particularly to a method for drawing out its external terminals.

[0002]

2. Description of the Related Art A conventional external lead-out structure of a sealed lead-acid battery will be described.

4 and 5 are perspective views of a conventional sealed lead-acid battery. In the sealed lead acid battery shown in FIG. 4, the electrode plate group is housed in the battery container 3 and the inner lid 4 having the electrode plate insertion holes 9 and 9'and the recesses 10 and 10 'is attached to the battery container 3 by an adhesive or heat welding. After fixing and soldering one end of the U-shaped faston terminals 1 and 1'to the positive and negative pole columns 5 and 5 ', respectively, the adhesive is filled into the depressions 10 and 10' to solidify and the inner lid is closed. The upper lid 2 is further mounted on the 4. And take out the battery output from the Faston tab terminals 1, 1'on the upper lid 2.
It is done by. In the sealed lead-acid battery of FIG. 5, the electrode plate group is housed in the battery container 3, the inner lid 4 is fixed to the battery container 3 by an adhesive or heat welding, and the parallel lead wire 8 having the connector 8a attached to the tip thereof. After being soldered to the positive and negative pole columns 5 and 5 ', respectively, an adhesive is filled in the depressions 10 and 10' to solidify them, and the upper lid 2 is mounted on the inner lid. In this example, the battery output is taken out from the parallel lead wire 8
And the connector 8a at its tip.

[0004]

However, in the conventional structure as described above, the bonding process is required at two points, namely, fixing the inner lid to charge the battery, and pulling out the pole portion from the inner lid. At the stage of sealing the above, two types of batteries of the same size with different external terminal shapes will be manufactured for the first time. For this reason, mass productivity is poor, which causes high cost of the battery.

The present invention solves such a problem, and the terminal for taking out the battery output is bent only on the inner lid or above the upper lid covering the inner lid.
It is an object of the present invention to provide a method for easily manufacturing two types of sealed lead-acid batteries of the same size having different external terminal shapes, and to reduce the man-hours required for manufacturing.

[0006]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the prior art. One end is connected to the pole of the electrode plate group housed in the cell and the other end covers the cell. In a sealed lead-acid battery having a terminal penetrating the end of the inner lid and projecting upward, a part of this terminal being embedded in an adhesive for fixing the inner lid to the electric charge, the end of the inner lid A simple method for two types of batteries having different external terminal shapes by arranging the bent position of the terminal penetrating the upper part and projecting upward from the upper surface of the inner lid or the upper lid covering the inner lid. It can be manufactured in.

[0007]

In such a method of the present invention, the terminal penetrating the end of the inner lid and projecting upward thereof is bent inward at the upper surface of the inner lid, or after attaching the upper lid, the upper lid is attached. There are two ways to fold inward from above. The former attaches a lead wire to the bent terminal and pulls out the end of this lead wire to the outside of the battery to create a lead-drawing type battery with a lead wire and a connector.
The latter can be made into a tab terminal type battery by bending the terminals above the upper lid.

EXAMPLES The details of the present invention will be described below with reference to examples.

FIG. 1 is an exploded perspective view of a sealed lead-acid battery according to an embodiment of the present invention. In FIG. 1, 3 is a cell of a sealed lead-acid battery, 5 and 5'are positive and negative pole poles taken out from the electrode plate group housed in the cell 3, and 7 and 7'are cells.
A part of the faston tab terminals 1, 1'of which one end is connected to the poles 5, 5'is housed in the terminal housing recesses 7, 7 '. Reference numeral 4 denotes an inner lid which is attached to the battery case 3, and at the end portion of the inner lid, the faston tab terminals 1, 1
Through holes 6, 6'are provided to allow 1'to penetrate therethrough.

FIG. 2 is a perspective view of a lead-lead type sealed lead-acid battery using parallel lead wires after the battery cell 3 and the inner lid 4 are integrally bonded. The adhesive injected to the back surface of the inner lid 4 is shown in FIG. The inner lid 4 and the battery 3 are fixed with an agent. Then, the terminals 1, 1 ′ penetrating through the through holes 6, 6 ′ and projecting upward are bent inward along the upper surface of the inner lid 4 at the outlet a portion of the through holes 6, 6 ′. Then, by attaching the rear end of the parallel lead wire 8 having the connector 8a attached to the bent terminal 1 and 1'to the bent terminals 1 and 1'and mounting the upper lid 2 on the inner lid 4, a lead pull-out type The sealed lead-acid battery of is completed.

FIG. 3 is a perspective view of a tab terminal type sealed lead acid battery. This example is manufactured by the same process as the previous example up to the step of integrating the battery 3 and the inner lid 4, and then the upper lid 2 is mounted on the inner lid 4 and then the tab terminals 1 and 1'are attached to the upper lid 2. By bending inward at the upper part b, a sealed lead acid battery of the tab terminal type having the same shape as the conventional faston tab terminal is completed.

[0012]

As described above, according to the production method of the present invention,
Two types of different external terminal shapes can be used by simply bending the terminal protruding through the end of the inner lid to the upper side of the inner lid, either above the inner lid or above the upper lid that covers the inner lid. It is possible to easily manufacture a battery of a size and to reduce the number of man-hours for assembling the battery.
