Fig. 7 is the sectional view of A-A in Fig. 6.
Below in conjunction with Fig. 6 and Fig. 7, the working process of suspension cylinder of the present invention is described:
In the time that needs are treated plated product and are electroplated, to treat that plated product and conducting medium put into suspension cylinder of the present invention, again suspension cylinder is inserted in electrolytic solution, place the electrical conductor of cylindrical hollow in the periphery of suspension cylinder, and by described suspension cylinder Bonding pressure pump, described pressure pump connects the cavity ingress of stopper 11, opening power, pressurized air enters suspension cylinder inside by the cavity of stopper, blows and treats plated product and conducting medium.
Treat that plated product and conducting medium are under the promotion of air-flow, enter and electroplate chamber 5 by the passage of flowing lumen 7, carry out electroplating process, in the electroplating process for the treatment of plated product, treat that plated product and conducting medium drop to the ingress of the inner bottom part 8 of inner tube structure along dividing plate 6, now, treat that plated product and conducting medium are under the drive of air-flow, the chamber 7 that again circulates then enters plating chamber 5 and again electroplates.
Continue circulation above-mentioned steps, until treat that the coating of plated product meets the specification of demand, turn off power supply, finish to electroplate.
There is following some difference in suspension cylinder of the present invention and electro-plating roller of the prior art:
1, electro-plating roller of the prior art is traverse setting.When plating, treat plated product together with conducting medium in cylinder along with cylinder rotate.
Therefore in electroplating process, treat plated product and treat between plated product and product and conducting medium between be all close contact and rub along with the rotation of cylinder, thereby cause the scuffing of surface abrasion or the coating surface for the treatment of plated product.
And suspension cylinder of the present invention is to adopt upper and lower opening structure, in whole electroplating process, suspension cylinder is all fixed, thereby the pressurized air that electroplating process is depended on pressure pump to be produced is sent into through the cavity entrance of the stopper of suspension cylinder below and in the cylinder of suspension cylinder, will be treated that plated product and conducting medium upwards blow through flowing lumen and send into plating chamber, thereby realizes electroplating process.
Therefore in the time adopting suspension cylinder of the present invention to treat plated product and electroplate, by blowing of air-flow, make to treat between plated product or treat to have avoided directly contacting between plated product and conducting medium, thereby greatly reduce the wearing and tearing of product surface to be plated and the scuffing of coating surface.
2, while treating plated product and electroplate with electro-plating roller of the prior art, owing to treating that the plating of plated product is along with the rotation of electro-plating roller starts, and finishes along with stopping operating of electro-plating roller.
Therefore, in whole electroplating process, all plated products for the treatment of are all electroplating by rolling of " following the trend " formula, easily cause the validity and reliability of electroplating effect to reduce.
And while adopting suspension cylinder of the present invention to treat plated product to electroplate, because exit, the upper end surrounding at flowing lumen 7 is provided with downward-sloping dividing plate 6, described dividing plate 6 can will treat that plated product again enters plating chamber by flowing lumen by pressurized air and electroplates in electroplating process, and so forth.
Therefore adopt when the invention provides suspension cylinder and electroplating, described batch, the electroplating process of circulation, can ensure reliability and the validity of electroplating effect.
3, because electro-plating roller of the prior art is traverse setting, so treat plated product and conducting medium easily misses by the cylinder of cylinder in electroplating process, ensure to treat that plated product and conducting medium can not spill in electroplating process if wanted, just must the hole also less than the diameter for the treatment of plated product be set at the cylinder of electro-plating roller, or the cylinder of cylinder arranges filter screen, but because electro-plating roller is horizontal placement, so in the time of rollers roll, easily damage filter screen.
Therefore in the situation that treating that plated product is more and more meticulousr, small and exquisite, on electro-plating roller, the more and more less hole of processing can be improved design accuracy and the production cost of electro-plating roller undoubtedly.
And in suspension cylinder of the present invention, because described suspension cylinder is stand-type design, so if treat that plated product and conducting medium are not blown afloat by air-flow in dropping process, the upper surface that only can fall described stopper 11.Because the upper surface of described plug 11 is provided with filter screen, treat if ensure plated product and conducting medium not from filter screen by as long as the mesh diameter of filter screen is made as and treats that the diameter of plated product and conducting medium just can described in being less than, and described filter screen and described stopper 11 are detachable connection, so described filter screen is easy Design and Machining not only, is also convenient to periodic replacement.And the utility model is owing to being stand-type setting, motionless in electroplating process, so the filter screen of urceolus periphery also can not be affected.
Therefore, suspension cylinder of the present invention is with respect to electro-plating roller of the prior art, not only simple in structure, and can effectively reduce production cost and the design accuracy of electroplating device.
4, microminiaturization is the direction of electronic devices and components development, miniature patch component size develops into 0603 (1.6*0.8mm), 0402 (1.0*0.5mm) from 1206 original (3.2*1.6mm) at present, even 0201 (0.5*0.25mm), these elements all need to be in two end electrodes electroless nickel layer and tin layer in order to welding and protection against corrosion.
While adopting electro-plating roller of the prior art to treat plated product to electroplate, because the diameter dimension of conducting medium cannot be accomplished infinitely small (conducting medium is substantially all more than 0.4mm at present), therefore in the time that plated product is miniature workpiece, the size of conducting medium will be far longer than the size for the treatment of plated product, when large-sized conducting medium and undersized in the time that plated product is close together rolling plating, due to the principle of work of electroplating technology, in electroplating process, easily cause treating the bonding coating in two ends of plated product or directly damage and treat plated product, so electro-plating roller of the prior art cannot meet electroplating technology and the electroplating effect requirement of miniature workpiece.
Add man-hour and adopt suspension cylinder of the present invention to treat plated product, because having adopted air lift pump, the suspension cylinder of vertical structure provide air-flow constantly to blow treat plated product and conducting medium in electroplating process, so avoided treating plated product and conducting medium being in contact with one another in electroplating process, therefore there will not be and treat the two ends bonding coating of plated product or treat the impaired phenomenon of plated product.
Therefore, suspension cylinder of the present invention can meet the requirement of electroplating technology and the electroplating effect of miniature workpiece.

In sum, while adopting suspension cylinder of the present invention to treat plated product to electroplate, can reach following some beneficial effect:
1, simple in structure, cost;
2, between product and product and product and conducting medium, in electroplating process, contact probability reduces greatly, and then greatly reduces the probability that product surface scratches or coating scratches;
3, constantly the electroplating process of circulation can ensure reliability and the validity of electroplating;
4, blow the circulation of product and conducting medium by pressurized air, can ensure the homogeneity that product disperses, thereby effectively ensure the consistence of coating.
5, can meet the requirement of electroplating technology and the electroplating effect of miniature workpiece.
Meaning, floated electrochemical plating of the present invention can be applied to the workpiece of miniature sizes and electroplate, such as can be to 3.2*1.6mm, 1.6*0.8mm, 1.0*0.5mm, even 0.5*0.25mm equidimension and small workpiece thereof are electroplated, and electroplate thereby solved current drum-type from the angle of technology the problem that method cannot be electroplated miniature workpiece.
