Abstract
The invention discloses an electrodeposition device which comprises an electrodeposition tank, a cathode, a cathode moving rod, a gear, a gear mounting rod and a stirring paddle.When the electrodeposition device works, the anode moving rod is in horizontal reciprocating motion under action of external force, a rack on the cathode moving rod drives the gear to be in forward and backward circular motion, and in this way, an electrolyte quickly flows under stirring action of the stirring paddle; the outer edge of the stirring paddle is close to the surface of the cathode, so that a flow field, on the surface of the cathode, of the electrolyte is relatively uniform, and uniformity of thickness of a cathode electrodeposition layer in the electrodeposition process is improved.
Description
Technical field
The present invention relates to a kind of electric deposition device, particularly to a kind of device improving cathode electrodeposition layer thickness homogeneity.
Background technology
At present, in commercial production, for increasing electrodeposition rate and effects of ion diffusion velocity, often increase electrolyte agitating device.The stirring of electro-deposition (include plating, electroforming) electrolyte is used mostly air stirring, liquid circulation stirring or cathode moving device.Although air stirring can make solution mix homogeneously, but for electrodeposition process requiring avoid the electrodeposition process of ionic oxide formation to use, and air stirring is it cannot be guaranteed that cathode surface forms stable flow field, so the uniformity of electro-deposition composition and deposition layer thickness all can be produced impact；In movable cathode agitating device, movable cathode stirring is easier to make cathode plane obtain the distribution of uniform mass transfer, but the intensity of movable cathode stirring is general not high, and the overall stirring action of whole galvanic deposition cell is relatively low, cause that deposition velocity is general not high, main cause is: conventional movable cathode stirring is that if workpiece negative electrode is flat thin lamellar, its stirring action is very weak to drive electrolyte movement by the shear action between workpiece (negative electrode) and electrolyte.Although there is multiple negative electrode agitating device to be developed so far, but still not up to very good effect.
Therefore, electrodeposition process can fully realize the mixing of electroplate liquid, can guarantee that again in the galvanic deposition cell of cathode surface flow field uniformity and carry out, just can be effectively improved the uniformity of deposition layer thickness.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide a kind of electric deposition device improving deposition layer thickness evenness.
The technical solution used in the present invention is: a kind of electric deposition device, including galvanic deposition cell, movable cathode bar, negative electrode, it is characterised in that: it includes gear, gear mounting rod and stirring paddle.Described negative electrode is arranged on movable cathode bar side；Described movable cathode bar is provided with tooth bar；Described rack and pinion engagement；Described gear is rotatable to be fixed on gear mounting rod；Described gear mounting rod is fixed on galvanic deposition cell wall；Described stirring paddle coaxial line is arranged on gear shaft.
Preferably, described movable cathode bar is set in parallel in above galvanic deposition cell wall.
Preferably, described movable cathode bar can move reciprocatingly under external force.
Preferably, its quantity can be increased and decreased by described gear shaft according to the size of galvanic deposition cell and technological requirement.
Preferably, being provided with certain distance between stirring paddle outer rim and cathode plane, it is apart from adjustable.
Preferably, described stirring paddle adopts the electrically insulating material of resistance to chemical attack.
Mechanical work principle involved in the present invention is: when movable cathode bar does horizontal reciprocating movement under the effect of external force, rack drives gear on movable cathode bar does rotating circumference telemechanical, gear driven stirring paddle does positive and negative circular motion, electrolyte quickly flows under the stirring action of stirring paddle, in addition stirring paddle outer fringe position is nearer with cathode plane, therefore, electrolyte is relatively uniform in the flow field of cathode surface, so that the uniformity of cathode electrodeposition layer thickness plays a role in improving in electrodeposition process.
During work, the quantity of stirring paddle and size can be replaced according to process requirements, to obtain different stirring intensities and flow field size so that cathode surface or (with) whole galvanic deposition cell obtains different mixing effect.Stirring paddle nonlinear type from top to bottom is distributed to reduce its shielding action to the electric lines of force in galvanic deposition cell.
The present invention has the advantage that 1 compared to existing technology, simple in construction, with low cost: only need to add gear, stirring paddle and gear mounting rod on existing movable cathode agitating device and can realize agitating function, and without extra power source system.2, the uniform mixing effect of high intensity is obtained: realized the quick diffusion of electrolyte by the positive and negative circular motion of nearly negative electrode of stirring paddle, the electrolyte in nearly cathode plane and whole dislodger can be made can to obtain the uniform mixing effect of high intensity.
