AI Technical Summary
Traditional large capacitors are prone to dripping after electrolyte filling, which can lead to contamination and affect the accuracy and efficiency of the filling volume.
An electrolyte filling device using aluminum electrolytic capacitors includes a pusher assembly and a guide assembly. The electrolyte filling volume is adjusted by the cooperation of a threaded rod and a sliding plate, and the electrolyte dripping is prevented by the cooperation of a tension spring and a guide post after filling.
It achieves accurate electrolyte filling and prevents electrolyte waste, ensures precise control of the filling volume and prevents dripping, and improves production efficiency.
