Description

Technical Field

[0001] The utility model mainly relates to the technical field of assembly machines, and in particular to a liquid injection device for an assembly machine. Background Art

[0002] Capacitor, short for capacitance, is one of the electronic components used in large quantities in electronic devices. It is widely used in DC isolation, coupling, bypass, filtering, tuning circuits, energy conversion, control circuits, etc. The main structure of a capacitor includes an aluminum shell, an element and a rubber plug. The positive and negative electrodes of the capacitor element are made of high-purity aluminum foil. The positive and negative electrodes are separated by electrolytic paper impregnated with electrolyte. The outside is composed of a rubber plug and an aluminum shell. Two pins are fixed on the element. The two pins pass through the rubber plug and extend to the outside of the aluminum shell. Normally, the element needs to contain gold in the electrolyte. After the aluminum shell, element and rubber plug are produced, they need to be assembled in a capacitor assembly machine.

[0003] For example, the Chinese patent publication number CN209591811U provides an aluminum electrolytic capacitor impregnated with electrolyte for automobile charging piles. The above application uses vacuum and two sets of ultrasonic vibrator groups to break the bubble layer in the gap between the solid dielectric layer of the capacitor element by ultrasonic waves, so that the electrolyte can easily replace the bubble layer, and the electrolyte can penetrate the electrolytic paper in all directions. For example, the Chinese patent publication number CN214378060U provides a capacitor assembly machine, including a frame, a rotating disk, an element assembly mechanism and an aluminum shell assembly mechanism.

[0004] In the prior art, the capacitor elements need to be immersed in a capacitor electrolyte impregnation device before being assembled on an assembly machine. However, during the impregnation process, the capacitor may absorb too much electrolyte, resulting in uneven electrolyte distribution, affecting the performance and consistency of the capacitor. After the electrolyte is impregnated, the capacitor needs to be dried to remove excess electrolyte. The impregnation process requires the use of a large amount of electrolyte, which increases production costs and environmental pollution risks. Utility Model Content

[0018] The utility model sets a liquid-pointing mechanism.
