Abstract

The utility model discloses a FPC (Flexible Printed Circuit) board electroplating liquid circulation treatment device which comprises a main electroplating tank (1) and a circulating tank (2), wherein both a liquid discharging pipe (3) and an overflow pipe (4) of the main electroplating tank (1) are connected with a liquid feeding part (5) of the circulating tank (2); liquid of the liquid feeding part (5) is filtered through a vertical filter net (7) and then flows into a liquid discharging part (6); a liquid pumping pipe (8) is arranged in the liquid discharging part (6) and is connected with a filter (9), a circulation pump (10) and the main electroplating tank (1). The device has the beneficial effects that impurities at the bottom of the main electroplating tank and impurities floating on the liquid surface can be removed at the same time; a pre-filtering device is additionally arranged, so that the workload of the filter is reduced; the impurity deposition is avoided, the impurities can be discharged along with liquid in time, and the impurity removal efficiency is greatly improved.

Description

A kind of FPC plate electroplate liquid cyclic processing device

Technical field

The utility model relates to circuit board electroplating technical field, particularly a kind of FPC plate electroplate liquid cyclic processing device.

Background technology

During existing FPC plate is produced, the filtration of electroplate liquid, a filter is normally set, the inlet pipe of filter is fixed on the bottom of plating tank, go out the top that pipe is fixed on plating tank, this just makes filter working load large, cannot be clean by being deposited on bottom land and swimming in contaminant filter on liquid level, easily cause workpiece contamination.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of FPC plate electroplate liquid cyclic processing device that reduces filter working load, improves dust removal rate is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of FPC plate electroplate liquid cyclic processing device, it comprises electroplates major trough and circulation groove, the bottom of electroplating major trough is provided with liquid discharge pipe, the top of plating tank is provided with upflow tube, the inside of circulation groove is provided with the vertically passing filter screen that the cavity volume of circulation groove is divided into feed liquor portion and fluid portion, liquid discharge pipe and upflow tube are all connected the feed liquor portion of circulation groove by pipeline, the liquid that flows into feed liquor portion flows into fluid portion after vertical strainer filtering, in fluid portion, be provided with pumping pipe, pumping pipe connects filter and recycle pump successively, the liquid pumping side of pumping pipe is positioned at the middle part of fluid portion, pumping pipe connects the liquid-inlet pipe of filter, the drain pipe of filter connects the fluid inlet of recycle pump, the leakage fluid dram of recycle pump is connected and is electroplated major trough by circulation fluid input tube, the drain side of circulation fluid input tube is positioned at the bottom of electroplating major trough.

The bottom surface of described plating major trough is to the inclined-plane of lopsidedness that liquid discharge pipe is set.

The utlity model has following advantage: the utility model can be removed simultaneously and electroplates major trough bottom land and swim in the impurity on liquid level, by setting up pre-filtrating equipment, by the larger impurity of vertical filter screen elimination volume, realize the pre-filtering to liquid, reduce the working load of filter; Electroplating the bottom surface of major trough is designed to the inclined-plane of lopsidedness that liquid discharge pipe is set, thereby the bottom surface that the liquid of guiding plating major trough bottom forms electroplating major trough forms flowing of souring, forming electroplating washing away of major trough bottom land, be more conducive to the discharge of the impurity of deposition when liquid discharge pipe is discharged; The liquid that is pumped into plating major trough bottom through circulation fluid input tube plays washing action to the bottom of electroplating major trough, has avoided the deposition of impurity, is beneficial to impurity and discharges in time with liquid; The combination of above-mentioned multiple removal of impurities structure, has improved dust removal rate greatly, has reduced the working load of filter simultaneously, is beneficial to equally raising dust removal rate.
