Embodiment
The core of the present invention is to provide a kind of electroplanting device, and the electroplanting device can be with the electricity of each anode unit of independent control
Stream.
In order that those skilled in the art more fully understand the present invention program, below in conjunction with the accompanying drawings and it is embodied
The present invention is described in further detail for mode.
It refer to Fig. 1, the schematic diagram for the electroplanting device that Fig. 1 is provided by the embodiment of the present invention.
Electroplanting device involved in the present invention, including anode and negative electrode 3, several works to be electroplated are connected with negative electrode 3
Part, anode are correspondingly arranged with negative electrode 3.Herein, anode is arranged to several separate anode units 5；That is, several sun
Pole unit 5 is not attached to together each other, is not common anode in structure.
Each anode unit 5 is respectively connected with power supply handset 2 so that each anode unit 5 can independently export different
Electric current makees ion exchange；So, in coating bath, electric current all same that each anode unit 5 is released so that electric current it is equal
Weighing apparatus degree is effectively guaranteed, so as to make the surface quality integrally electroplated more preferably, while preferable coating average degree is realized,
Also shorten the time of plating；In addition, each connecting the power of the power supply handset 2 of anode reduces；So it is coordinated to design one
During a little special automatic assembly lines, very big flexibility is had.
Certainly, according to being actually needed, each anode unit 5 can independently release appropriate electric current, to ensure that its is respective
Plate surface has higher quality.
Specifically, the quality of electroplating quality is inseparable with the evenness and stability of electroplating current density, in order that
The evenness and stability of electroplating current density are improved, single assistant anode unit 5 is arranged to herein by by anode, and
Each anode unit 5 is all connected with power supply handset 2, so, is respectively formed by each anode unit 5 of power supply handset 2
Respective plating loop, so as to realize that the current value in each plating loop is identical, avoid under setting of the common anode to common cathode
Carry out electroplating technology.
In other words, there is employed herein the measure of each electric current of anode unit 5 of independent control, adjust and be designed to again
The electroplating rectifier of cooperation, and the positive output of each rectifier is independently connected an anode unit 5.So that each anode list
Member 5 is all controlled by independent electroplating system, flows consistent constant current, and order plating is average, and effect is more high-quality, when shortening plating
Between.
Herein, because the volume of power supply handset 2 is generally smaller, therefore the coordination galvanization of power supply handset 2 can be utilized to produce
Line carries out flexible design；I.e., it is possible to directly directly carry anode unit 5 using the positive output part of power supply handset 2；Such one
Come, the stabilization of electric current can be equally efficiently controlled, so as to realize the high-quality purpose of above-mentioned electroplating effect.
In order to realize the normal operation of above-mentioned power supply handset 2, several power supply handsets 2 are parallel to same power supply herein
On machine tool 1；And power supply handset 2 is also associated with control device, control device can control the independent output of several power supply handsets 2
Appropriate electric current.
That is, electroplanting device provided by the present invention, all workpiece are still connected on together, are common cathode；But
Anode is divided into several anode units 5, several anode units 5 are not connected together each other, are no longer common anode in structure, but
Several anode units 5 are connected with the mains handset 2 independently of one another.By control device, make the independent output of each anode unit 5
Different curtages make ion exchange.
Under this setup, the electric current and voltage of each assistant anode unit 5 can be controlled；In some cases,
Some granting electric currents in the anode unit 5 of low potential near workpieces can be flexibly even improved, makes each workpiece while receives
Consistent or indivedual extra high current densities.
Certainly, according to being actually needed, all anode units 5 can also be controlled to release same curtage.Due to plating
Multiple tiny plating loops are subdivided into by the loop of a high current originally in groove；Therefore, the electricity of each anode unit 5 is flowed through
Stream will substantially reduce, and required power also can be small.The demanded power output of power supply handset 2 will be greatly reduced；Such one
Come, it can realize miniature, and its output end can be directly connected to anode unit 5, and single unit system is in coating bath adjacency, reduction
Transmit the loss of electric current.
More specifically, power supply machine tool 1 is high tension transformer, 220V or 380V input voltages can be converted into 24V
Voltage is simultaneously exported to power supply handset 2；In addition, power supply handset 2 is lower pressure transducer, for 24V input voltages to be converted into 6V electricity
Press to carry out electroplating work procedure.
That is, because whole coating bath and peripheral device belong to electric conductor, therefore its input operation voltage can not
Carried out with 220V or 380V, serious industrial injures and deaths can be caused because of accidental shock.Therefore, power supply handset 2 may only use low input
Voltage means operate.
In general, the voltage for electroplating application is all below DC12V, as long as so when power supply handset has DC24V inputs, it
Enough voltage can be substantially exported, deals with the plating requirement of all kinds of different metals.Because power supply handset needs DC24V input electricity
Source, therefore need a powerful DC24V power supply to carry out transmission ＆ distribution electric energy after its machine.Set forth herein method be first to use power supply machine tool 1
220V or 380V are changed into DC24V voltages, be then connected to all power supply handsets 2 in coating bath allow power supply handset independently-powered again in
Anode unit 5.
Power supply handset 2 is fixed on copper bus-bar 3 herein by bolt 7；That is, copper of the power supply handset 2 with being connected workpiece
Bus-bar 3 is fixed；Furthermore, it is possible to which anode unit 5 is arranged into titanium alloy wire basket, and electricity is placed with titanium alloy wire basket
Plate metal 51；In addition, several workpiece to be electroplated are connected with copper bus-bar 3.
By Figure of description 1 as can be seen that power supply machine tool 1 is connected with copper bar 4 and copper bar loop 41 by cable 6, copper
Row 4 and copper bar loop 41 pass through the fixed power source handset 2 of bolt 7；That is, the titanium alloy wire basket as anode unit 5 is directly connected to
In power supply handset 2, and plating metal 51 is placed in titanium alloy wire basket.
Specifically, in actual production process, each anode opposing cathode, different impedance values is inevitably had,
That is Europe Mu Shi laws.These different impedance values are derived from the quantity variance of plating metal 51, anode list in titanium alloy wire basket
Position of the thickness and quantity and titanium alloy wire basket of guarantor's bag of member 5 in electroplating assembly line etc. factor.In addition, these hinder
It is anti-to exist because of reasons such as the depositions in the consumption of material and the bag of anode unit 5 of the plating metal 51 in titanium alloy wire basket
Changed in electroplating process.
Therefore, it is unequal and unstable to result in electroplating current density in conventional plating process for above-mentioned reason.And herein
Used mode, each anode unit 5 is gone to isolate with different plating loops.Then, no matter individual anode unit 5 itself
How many impedance, or how to change, it can also go monitoring to coordinate with independent plating loop in new method.
Pass through power supply handset 2 so that DC24V control sources, and the function of thering is constant current (or constant current mode) to export.
Certainly, the maximum output voltage of power supply handset 2 only can be in below DC24V.Under this setting, each independent titanium can be set and closed
The stable current value of golden wire basket granting.In electroplating process, different titanium alloy wire baskets have different resistance values even
Change, plating loop, which can also coordinate, changes output voltage to accomplish the effect of constant current, finally makes the electric current in whole coating bath
Density reaches consistent.
Further, since power supply handset 2 needs DC24V control sources, therefore primary power source is equipped with herein and carrys out transmission ＆ distribution electric energy.Example
Power supply machine tool 1 as used herein, the DC24V voltage sources for the civil power conversion output stabilization that it lies prostrate AC220, is then connected to coating bath
In interior all power supply handsets 2, then power supply handset 2 is allowed to go independently-powered to give each titanium alloy wire basket.
Certainly, the electroplanting device involved by this paper, the concrete numerical value of above-mentioned DC24V and AC220 volt can also be it
He, only provides a kind of specific embodiment herein, and the voltage of other numerical value is also within this paper protection.
Certainly, it is necessary to which explanation, anode unit 5 is not necessarily titanium alloy wire basket, can also use other materials
As anode unit 5, a kind of embodiment is only provided herein herein.
In above-mentioned set-up mode, because the rectifier power of each jointed anode unit 5 is very low, it is not necessary that each
All be directly connected to power transmission and distribution and take input power, so this paper presents the mode of this stacked buck, order to design it is more flexible and
It is safer.Such as herein by each low-power rectifier of anode unit 5 directly with the copper bar 4 and copper bar of two 24 volts of voltage differences
Loop 41 connects power supply, and it (is, for example, the negative of anode low-power rectifier to bear to bear a heavy burden with copper bar 4 and copper bar loop 41
Weight, or the heavy burden of anode)；Because 24 volts of voltages for belonging to safe range, do not form injury to human body, so even if the He of copper bar 4
Copper bar loop 41 is exposed to the open air, also will not relate to the problem of safe.
In addition, the number of the titanium alloy wire basket as anode unit 5 herein can be arranged on 2 to 200 it
Between.
Certainly, according to being actually needed, the number of titanium alloy wire basket can also be other, however it is not limited to as described herein 2
Between individual to 200；The titanium alloy wire basket of other numbers should also will not be described in great detail herein within this paper protection domain.
Electroplanting device provided by the present invention is described in detail above.Specific case used herein is to this hair
Bright principle and embodiment is set forth, the explanation of above example be only intended to help the method for understanding the present invention and its
Core concept.It should be pointed out that for those skilled in the art, the premise of the principle of the invention is not being departed from
Under, some improvement and modification can also be carried out to the present invention, these are improved and modification also falls into the protection of the claims in the present invention
In the range of.
