産業上の利用分野
本発明は蓄電池部品製造装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a storage battery component manufacturing apparatus.
従来の技術
従来、円筒密閉形ニツケルカドミウム電池の陽
極端子として用いられる蓋の製造は、一般に端子
と受皿を溶接する方法と端子外周を受皿の外周に
折曲げて構成するカシメ方法等がある。BACKGROUND ART Conventionally, the lid used as an anode terminal of a sealed cylindrical nickel cadmium battery has been manufactured by two methods: welding a terminal and a saucer, and crimping the terminal by bending the outer periphery of the terminal to the outer periphery of a saucer.
いずれの方法においても、電解液漏洩を防止し
かつ容器内ガス圧の異常上昇時に作動する安全弁
機構を端子と受皿間に具備している。 In either method, a safety valve mechanism is provided between the terminal and the saucer to prevent electrolyte leakage and to operate when the gas pressure inside the container increases abnormally.
安全弁機構はゴムの弾性を利用したゴム弁方式
や、掛止板をスプリング加圧した方式等が市場に
提供されている。 The safety valve mechanisms available on the market include a rubber valve system that utilizes the elasticity of rubber, and a system that uses a spring pressurized locking plate.
発明が解決しようとする問題点
安全弁の有無や、誤組込による弁機能の不備
は、密閉形電池の機能を失わせるものであり、蓋
の製造は高い精度を要求され、万一不良品が発生
した場合には完全にこれを排除しなければなら
ず、製造した後に検査する方法では、不良品混入
の危険が大きく製造装置内で品質保証しなければ
ならない。Problems to be Solved by the Invention The presence or absence of a safety valve or a defect in the valve function due to incorrect installation will cause a sealed battery to lose its function.The manufacturing of the lid requires high precision, and in the unlikely event that a defective product is produced. If this occurs, it must be completely eliminated, and with the method of inspecting after manufacturing, there is a high risk of contamination with defective products, so quality must be guaranteed within the manufacturing equipment.
問題点を解決するための手段
本発明は上記の点に鑑み、端子外周を折曲げる
カシメ工程の金型であるポンチ内から圧縮空気を
送り出し、安全弁機構を加圧して定圧力の保圧経
過時間を計測することりより、弁の有無を検知し
た後定圧以上の加圧時に二次側圧力を計測して安
全弁機能を検査することにある。Means for Solving the Problems In view of the above-mentioned points, the present invention sends compressed air from inside the punch, which is a mold for the crimping process that bends the outer periphery of the terminal, pressurizes the safety valve mechanism, and maintains a constant pressure for an elapsed time. Rather than measuring the presence or absence of the valve, the safety valve function is inspected by measuring the secondary pressure when pressurizing above a constant pressure after detecting the presence or absence of the valve.
作 用

に示す。Embodiment A caulking mold is constituted by a die 2 incorporating a push-up pin 1 that is slidable in the vertical direction and a punch 3. The push-up pin 1 is fitted into an O-ring 4, and is designed to prevent it from falling out due to its own weight loaded with a terminal 5, a rubber valve 6, and a saucer 7. With the push-up pin 1 in the upper position, the saucer 7, the rubber valve 6, and the terminal 5 are sequentially supplied to the upper part of the push-up pin 1. FIG. 1 shows the state when supply is completed.

は組込不良を検査する。 Next, the punch 3 is lowered by hydraulic or pneumatic pressure to compress the upper surface of the terminal 5. The terminal 5 is bent by the compressive force into a shape in which the terminal collar 8 wraps around the saucer 7 along the die 2, and the caulking process is completed. At this time, after compressed air is supplied through the vent hole 9 provided in the punch 3, the punch 3 is closed, and the holding pressure sensor 10 is used to confirm that the pressure does not drop within a certain period of time to check for the presence of a rubber valve or for improper installation.

能を検査する。 Furthermore, after sealing the hollow hole 11 provided in the push-up pin 1 with a sealing plate 12, a pressure higher than the holding pressure measurement pressure is supplied through the vent hole 9, and the relief pressure sensor 13 detects a pressure higher than a certain level. Check safety valve function.

で新たに発生すると考えられる。Effects of the Invention As described above, according to the present invention, since the compressed air for detection is supplied from within the punch which is the processing die, there is no need to provide a separate inspection process.
It is now possible to downsize manufacturing equipment, and it is thought that new problems will occur during the inspection process.
