Description

Technical Field

[0001] The utility model belongs to the technical field of capacitor manufacturing, in particular to a device for opening and aging of tantalum capacitors. Background Art

[0002] During the manufacturing process of tantalum capacitors, they need to be clamped in a special fixture. After acid injection, the tantalum capacitors are opened and aged to facilitate the subsequent production of the tantalum capacitors. If the fixture is combined with the storage and acid injection structure, production efficiency can be greatly improved.

[0003] Patent document CN103050285A discloses a novel acid injection fixture for ultra-large-capacity capacitors and its acid injection method, comprising the following steps: placing the capacitor on the support seat of the acid injection fixture; inserting the acid injection syringe into the acid injection syringe insertion hole at the upper end of the acid injection syringe and sealing the contact area; then injecting electrolyte through the acid injection syringe, and the electrolyte flows into the capacitor through the acid injection syringe; placing the entire acid injection device in a vacuum machine to evacuate the air inside the capacitor through the acid injection syringe; then stopping the vacuuming and introducing air into the vacuum cover. The negative pressure inside the capacitor draws the electrolyte in the acid injection syringe into the capacitor. Although the patent discloses structures such as the pressure plate, support seat, and acid injection syringe, it does not disclose the components that fix the capacitor.

[0004] The patent document with announcement number CN201741588U discloses an aging fixture for electrolytic capacitors with a high one-time yield. It includes an insulating plate, a positive conductive plate and a negative conductive plate provided with a conductive sheet. The three are clamped by bolts to the positive and negative electrodes of the capacitor to be aged to form an aging fixture. The fixture is characterized in that a groove for installing a thermistor is provided on the positive conductive plate. One end of the thermistor is connected to the positive electrode of the capacitor to be aged, and the other end is connected to the conductive sheet. The utility model has a simple structure. During aging, when a capacitor fails and short-circuits, the thermistor is a positive temperature coefficient thermistor and is not easily burned out. Therefore, the aging time and aging environment of each capacitor are consistent during the aging process, thereby improving the quality of the capacitor. However, the fixture does not include acid injection-related components. The acid injection process needs to be used in conjunction with other devices, which affects production efficiency to a certain extent. Utility Model Content
