Abstract

The utility model discloses a deplating stripping recovery groove comprising a groove body, flying target stands and flying targets. The plurality of flying target stands are symmetrically fixed on upper edges of the two sides of the groove body, and the flying target stands are arranged in interval, the plurality of flying targets are supported on the flying target stands, the flying targets hanging copper plate are connected with negative pole of DC source, the flying targets hanging copper-plated hook are connected with positive pole of DC source, the flying targets connected with the positive pole are arranged among the flying targets connected with the negative pole, the flying targets connected with the negative pole are arranged outside of the flying targets connected with the positive pole, the groove body contains solution containing sulfuric acid, hydrogen peroxide solution and copper sulphate, and the plurality of copper plate and the plurality of copper-plated hook are submerged in the solution. The utility model can simultaneously strip and reclaim copper on the hook, and has advantages of simple process, simple structure and environmental protection.

Description

Reverse electroplating peeling hung recovery tank

Technical field

The utility model relates to a kind of copper retrieving arrangement, especially a kind ofly is used to reclaim the device that flies the copper that is coated with on the target hook after PCB electroplates.

Background technology

Electroplating technology in the PCB manufacture craft is that the target that flies that PCB is hung on electrolyzer is linked up with enterprising electroplating, flying on the hook of target also can plated with copper, the technology of the traditional copper-stripping that will link up with is stripping and hanging, stripping and hanging is that hook is immersed in the salpeter solution, the copper on hook surface is corroded by nitric acid and is peelled off, though the copper on hook surface is to have removed like this, but consume a large amount of salpeter solutions, increased simultaneously that waste gas reclaims and the expense of off gas treatment and strengthened the pollution of environment and the treatment process of cupric nitrate waste liquid, copper peels off not only contaminate environment but also cost of idleness like this.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of reverse electroplating peeling hung recovery tank, and this reverse electroplating peeling hung recovery tank both can have been finished peeling off and reclaiming of copper, had simplified operation again, had saved cost, and environmental protection again simple in structure.

The utility model for the technical scheme that solves its technical problem and adopt is:

A kind of reverse electroplating peeling hung recovery tank, comprise cell body, fly target stand and fly target, top, corresponding both sides is symmetrically fixed with some target stands that fly on the cell body, and flying target stand is set in distance, but some target framves that fly are in flying on the target stand, hang with the negative pole that target connects direct supply that flies of copper coin, be with the positive pole that target connects direct supply that flies of copper facing hook, all connect anodal and fly target and be in all and connect flying among the target of negative pole, and all targets that fly that connect negative pole are in all and connect anodal and fly outside the target, be equipped with in the cell body and contain sulfuric acid, the solution of hydrogen peroxide and copper sulfate, some copper coins and some copper facing hook are dipped in this solution.Overhead traveling crane will carry out the target that flies of the galvanized some band copper facing hooks of PCB and deliver to anti-plating stripping groove from discharging area, fly target holder in flying on the target stand, after circuit is connected, because anti-electroplating principle, copper on the some copper facing hooks that are connected with dc power anode is dissolved in the solution with the form of cupric ion, cupric ion is separated out and is adsorbed on the copper coin from the copper coin that is connected with power cathode again, has realized peeling off and reclaiming of copper.

Further technical scheme of the present utility model is:

The described target that flies that connects negative pole is provided with two and be positioned at the other both sides of cell body, and the described anodal that connects flies the middle part that target is positioned at cell body.

The beneficial effects of the utility model are: because top, corresponding both sides is symmetrically fixed with some target stands that fly on the cell body, and flying target stand is set in distance, but some target framves that fly are in flying on the target stand, hang with the negative pole that target connects direct supply that flies of copper coin, be with the positive pole that target connects direct supply that flies of copper facing hook, all connect anodal and fly target and be in all and connect flying among the target of negative pole, and all targets that fly that connect negative pole are in all and connect anodal and fly outside the target, be equipped with in the cell body and contain sulfuric acid, the solution of hydrogen peroxide and copper sulfate, some copper coins and some copper facing hook are dipped in this solution, this example can be simultaneously with copper-stripping on the hook and recovery, operation is simple, and the environmental protection again simple in structure of this example.

Embodiment

Embodiment: a kind of reverse electroplating peeling hung recovery tank, comprise cell body 1, fly target stand 2 and fly target 3, top, corresponding both sides is symmetrically fixed with some target stands that fly on the cell body, and flying target stand is set in distance, but some target framves that fly are in flying on the target stand, hang with the negative pole that target connects direct supply that flies of copper coin, be with the positive pole that target connects direct supply that flies of copper facing hook, all connect anodal and fly target and be in all and connect flying among the target of negative pole, and all targets that fly that connect negative pole are in all and connect anodal and fly outside the target, be equipped with in the cell body and contain sulfuric acid, the solution of hydrogen peroxide and copper sulfate, some copper coins and some copper facing hook are dipped in this solution.Overhead traveling crane will carry out the target that flies of the galvanized some band copper facing hooks of PCB and deliver to anti-plating stripping groove from discharging area, fly target holder in flying on the target stand, after circuit is connected, because anti-electroplating principle, copper on the some copper facing hooks that are connected with dc power anode is dissolved in the solution with the form of cupric ion, cupric ion is separated out and is adsorbed on the copper coin from the copper coin that is connected with power cathode again, has realized peeling off and reclaiming of copper.

Claims

1, a kind of reverse electroplating peeling hung recovery tank, comprise cell body (1), fly target stand (2) and fly target (3), top, corresponding both sides is symmetrically fixed with some target stands that fly on the cell body, and flying target stand is set in distance, but some target framves that fly are in flying on the target stand, it is characterized in that: the negative pole that target connects direct supply that flies that hangs with copper coin, be with the positive pole that target connects direct supply that flies of copper facing hook, all connect anodal and fly target and be in all and connect flying among the target of negative pole, and all targets that fly that connect negative pole are in all and connect anodal and fly outside the target, be equipped with in the cell body and contain sulfuric acid, the solution of hydrogen peroxide and copper sulfate, some copper coins and some copper facing hook are dipped in this solution.
