Abstract

PURPOSE:To facilitate fusion of terminal poles and lead wires by placing a lid, in which a cap-shaped protruding part is inserted into its terminal pole penetration portion, in its inverted position, placing the terminal poles and a separation-type material in the protruding part, and then exposing the tip of the pole terminal with the protruding part removed with a battery jar joined to the lid in its inverted position. CONSTITUTION:A cap-shaped protruding part 8 is inserted into the terminal pole penetrating part of a lid 1, and an adhesive 5 and a separation-type material 9 are applied or arranged in the part 8. Then, the adhesive 5 is filled in an inter-cell connecting body 4 arranged on the rear side of the lid 1, recesses 1a, 1b and a circular groove 1c with the rear side of the lid 1 facing upward, and a battery jar 2 is cemented, placing it upside down with a group of pole plates inserted in it. Subsequently, the storage battery is placed in its normal position and the cap-shaped protruding part 8 is removed from the lid 1. With the separation-type material 9 removed, the tip of the terminal pole 6 is protruded/exposed and a lead-wire 7 is soldered to it. This ensures reliability of the terminal portion of a storage battery such as increased ease of soldering work, enhanced soldering strength, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method of manufacturing a storage battery. Conventional technology and its problems A typical conventional storage battery manufacturing method in which the terminal pole is bonded to the lid at the same time as the battery case and the lid will be explained with reference to Fig. 3. As shown in FIG. 3, there is a recess 1 a in which the U-shaped intercell connector 4 and the terminal pole pillar 6 of the electrode plate group 3 are buried on the back surface of the Ill.
, 1b and an annular groove IC to be adhered to the battery case 2,
A battery case 2 in which the adhesive 5 is filled into the recess and the edge with the back side of the fil facing upward, and the electrode plate group 3 is inserted therein.
Turn them upside down, fit them together, and glue them together. By solidifying the adhesive 5 in this state, the lid, the battery case, and the terminal pole are bonded together at the same time. After this, the storage battery is returned to its normal position, and the upper part (B-ff) of the terminal pole 6 is removed by poling or the like using a drill to expose the tip of the terminal pole 6, as shown in FIG. Solder the lead wire 7 to the tip of the terminal pole post 6. However, in this battery structure, the tip of the exposed terminal pole is located at the bottom of the cylindrical recess formed by poling, making soldering work difficult and time-consuming, as well as making soldering reliable. It also had the disadvantage of being of low quality. Means for Solving the Problems The present invention provides a method of manufacturing a storage battery without interstitial points as described above, in which the upper end of the battery case and the intercell connection body of the electrode plate group are connected to the grooves provided on the back surface of the lid. Alternatively, in a storage battery that is fixed to a recess with an adhesive, a synthetic resin lid with a removable cap-shaped protruding part inserted into the terminal pole penetration part is placed in the opposite direction, and the cap-shaped protruding part is inserted inside the cap-shaped protruding part. After placing a non-adhesive mold release material on the terminal pole and adhesive, the grooves, recesses and through-holes of the pole pole terminal are filled with a self-adhesive agent, and the battery case loaded with the electrode plate group is turned upside down. The cap-shaped protruding part is fitted and adhesively bonded to the lid in an inverted state, and after the adhesive hardens, the cap-shaped protruding part is removed to expose the tip of the pole pole end to the outside. The product is characterized in that the welding between the terminal pole and the lead wire is facilitated by using a material that has a flux effect for welding or soldering the terminal pole as the release material placed inside the component. ．． EXAMPLE Hereinafter, an example of the present invention will be explained in detail with reference to the drawings. As shown in FIG. 1, a cap-shaped protruding part 8 into which the head of the terminal pole post 6 is inserted is inserted into the terminal-pole penetration part of the lid 1 made of synthetic resin, and the cap-shaped protruding part 8, which will be described later, is inserted into the cap-shaped protruding part 8. A non-adhesive release material 9 is applied or placed on the adhesive 5 and the terminal pole. After this, adhesive 5 is applied to the U-shaped inter-cell connector 4 placed on the back side of the lid 1, the four parts la and lb where the terminal pole pillar 6 is embedded, and the annular groove IC of the outer peripheral part that will be adhered to the battery case 2. ,lI! The battery case 2 with the electrode plate group 3 inserted therein is turned upside down, fitted, and bonded.

After this, the storage battery is returned to its normal position, the cap-shaped protrusion crystal 8 is removed from the lid 1, and the mold release material 9 is removed. As a result, as shown in FIG. 2, the tip of the terminal pole post 6 protrudes and is exposed, and the lead wire 7 is soldered to this. Note that the cap-shaped protruding part 8 is made of ABS on the lid.
When laI resin and PP resin are used, natural rubber, synthetic rubber, PP resin, etc. are suitable. Furthermore, when epoxy resin is used for adhesion and bonding, and lead alloy is used for terminal poles, silicone grease, olefin grease, etc. are suitable as the mold release material 9. Furthermore, if a paste-like soldering flux is used, it will act as a flux for welding and soldering between the terminal value column and the lead wire, and will be effective in the work of attaching the lead wires. Effects of the Invention The present invention is a method for manufacturing a storage battery as described above, and in the process of exposing the terminal pole from the lid, the terminal pole can be easily exposed without damaging the tip shape of the terminal pole that is suitable for soldering. Moreover, since the exposed part has a convex shape, the reliability of the battery terminal part is greatly improved by improving soldering workability and increasing soldering strength.
