Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a capacitor aging device.

Conventionally, various capacitors such as aluminum electrolytic capacitors and tantalum solid electrolytic capacitors generate an oxide film on the valve metal and use this film as a dielectric, but as the film deteriorates during the manufacturing process, a phenomenon called aging occurs. Treatment is being carried out to repair the film.

Conventionally, in order to perform aging treatment, a capacitor is fixed to a jig, the jig is housed in a constant temperature oven, and a voltage is applied to age the capacitor for a predetermined period of time. For this reason, the steps before and after the aging process are interrupted, making it impossible to perform each step in a continuous assembly line, which hinders the automation of capacitor manufacturing.

In view of the above points, it is an object of the present invention to provide a capacitor aging device that can automate the aging process.

In order to achieve the above object, the present invention provides a metal bar to which one terminal of a capacitor can be connected, a clamping plate that removably clamps the other terminal of the capacitor, and a metal bar connected to the clamping plate and connected to the clamping plate. It has a metal spring that is electrically connected to the terminal of the other electrode via a plate, a metal rail that the metal spring can contact and slide on, and a power source that can apply a voltage between the terminals of the capacitor. The present invention provides a capacitor aging device characterized by the following.

Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, reference numeral 1 denotes a plurality of capacitors such as tantalum solid electrolytic capacitors, each having terminals 2 and 3 of different polarity drawn out. 4 is
It is a metal bar made of aluminum, copper, etc. to which only one terminal 2 is connected. 5, as shown in FIG. 2, a back plate 6 and a holding metal fitting 7 are attached to an insulating fixing bar 8, and the other terminal 3 of the capacitor 1 is held and held by the holding metal fitting 7 against the back plate 6. The terminal 3 is a holding plate with a presser metal fitting 7 that can be lifted up so that the terminal 3 can be freely removed. 9 is a metal plate whose one end is connected to the metal bar 4 and the other end is connected to the fixed bar 8. 10 and 11 are metal springs connected to the presser fitting 7 and the metal plate 9, respectively. Metal rails 12 and 13 are in contact with metal springs 10 and 11, respectively, and are configured to slide together with the capacitor 1 at a predetermined speed. 14 is a power supply connected to the metal rails 12 and 13, and can apply any voltage to the capacitor 1.

That is, by sliding the metal bar 4 and the clamping plate 5 on the metal rails 12 and 13 of a predetermined length at a predetermined speed, it is possible to apply a voltage to the capacitor 1 for an arbitrary period of time and perform aging. Moreover, during aging, the capacitor 1 can be moved from the previous process to the next process without being fixed at an arbitrary position, making it easy to connect each process and making automation possible.

In addition, since the terminals 3 of the capacitor 1 are pressed against the back plate 6 and held by the individual presser metal fittings 7, if the capacitor 1 becomes punctured during aging, the puncture can be removed by lifting the presser metal fittings 7 and removing the terminals 3. Since the capacitor 1 can be removed from the aging process, the current will not be concentrated on one capacitor 1 and the aging process will not be interrupted for a long time.

Furthermore, if a thermal relay is connected to each metal rail 12, when capacitor 1 is punctured and a large current flows through the aging circuit, this thermal relay will be activated and automatically disconnect the punctured capacitor 1 from the circuit. , the aging process is not interrupted immediately, and unlike other fuses, activated thermal relays can be reset and used as fuses again, so there is no need for replacement work, and an inexpensive device can be obtained. It will be done.

As described above, according to the present invention, it is possible to obtain a capacitor aging device that is easy to automate and in which the aging process is hardly interrupted due to a punctured capacitor.
