Description

Technical Field

[0001] The utility model belongs to the technical field of capacitor production, and particularly relates to an assembly and test line for capacitors. Background Art

[0002] Power capacitors are capacitors used in power systems and electrical equipment. Any two metal conductors separated by an insulating medium in the middle form a capacitor. The capacitance of a capacitor is determined by its geometric dimensions and the characteristics of the insulating medium between the two plates. When a capacitor is used under an alternating voltage, its capacity is often expressed by its reactive power, with the unit being var or kvar.

[0003] A capacitor is an element that can store electric charges. It is one of the electronic components widely used in electronic devices and is widely applied in aspects such as DC blocking and AC passing, coupling, bypass, filtering, tuning circuits, energy conversion, control, etc. in circuits. It is an indispensable and important component in people's lives. In order to reduce labor costs and improve work efficiency, the automated production of capacitors becomes particularly important.

[0004] In the Chinese patent literature, there is a patent document with the publication number CN 109300712 B, titled "An Integrated Automatic Production Line and Production Method for Capacitor Oil Injection and Sealing Detection", which solves the above problems. The present invention provides an integrated automatic production line for capacitor oil injection and sealing detection, including an oil injection and sealing device and a detection device arranged and installed in sequence from left to right.
