Abstract
The invention discloses a nickel electroplating assembly line pretreatment device, which relates to the electroplating field and is applied to a workpiece nickel-plating pretreatment process. The nickel electroplating assembly line pretreatment device comprises a rail, a hanger which is arranged on the rail for suspending workpieces and operates along the rail, a chemical degreasing tank which is arranged on the bottom of the rail and used for treating workpieces on the hanger, an ultrasonic degreasing tank, a primary rinsing tank, a polishing tank, a secondary rinsing tank, a tertiary rinsing tank and an activating tank, wherein a cathode electrolytic cell is arranged between the secondary rinsing tank and the tertiary rinsing tank. The nickel electroplating assembly line pretreatment device has the effects that high-current cathode electrolysis is performed on the workpieces in a strong base solution to reduce oxide films on the workpieces, a large number of hydrogen ions are discharged on the cathode in the cathode electrolysis process to form nascent-state hydrogen ions with strong reducing capacity, the original oxide films are reduced into metals after the nascent-state hydrogen ions are adsorbed on the surface of the cathode, so that crystalline structures of the metals are sufficiently exposed, and therefore, a coating with good binding force can be obtained when the workpieces are electroplated.
Description
Technical field
The present invention relates to field of electroplating, be applied to workpiece nickel plating pretreatment procedure.
Background technology
Current workpiece plating line pretreatment procedure comprises chemical degreasing, ultrasonic oil removal, three washings, polishing, three washings, activation, and workpiece enters impact nickel groove and carries out nickel plating after sequentially passing through above-mentioned operation.Workpiece is after polishing, layer oxide film is formed at workpiece surface, carry out nickel plating when workpiece directly enters impact nickel groove, be actually and coating is plated on oxide film, so the bonding force of coating is poor, although activation also has the effect of removing oxide film, but DeGrain, activating topmost effect is form slight etching on workpiece metal surface, grabs with joint efforts to increase workpiece coating, but owing to there is oxide film, therefore activation effect is also not obvious.
Summary of the invention
The object of the invention is: a kind of electronickelling streamline pretreating device is provided, improve the bonding force of workpiece coating with the oxide film removing workpiece surface.
In order to achieve the above object, taked technical scheme is:
A kind of electronickelling streamline pretreating device, is characterized in that: comprise the hanger for hanging workpiece that track and track are provided with, described hanger orbiting; Also comprise and be arranged on rail base, for the workpiece on described hanger is processed chemical degreasing groove, ultrasonic oil removal groove, one-stage water wash groove, polishing trough, secondary washing bath, tertiary effluent washing trough, activated bath, between described secondary washing bath and tertiary effluent washing trough, be provided with cathode electrolytic cell.
The effect that the present invention reaches is: workpiece carries out high current cathode electrolysis to the oxide film reduced on workpiece in strong base solution, in catholyte process, a large amount of hydrogen ion discharges to be formed and has the hydrogen in statu nascendi ion of strong reducing power on negative electrode, after being adsorbed on cathode surface, original oxide film is made to be reduced into metal, thus fully manifest the crystal structure of metal, obtain the coating that bonding force is good when enabling workpiece electroplate like this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1. track; 2. hanger; 3. chemical degreasing groove; 4. ultrasonic oil removal groove; 5. one-stage water wash groove; 6. polishing trough; 7. secondary washing bath; 8. cathode electrolytic cell; 9. tertiary effluent washing trough; 10. activated bath.
Embodiment
From accompanying drawing 1, the present invention includes the hanger 2 for hanging workpiece that track 1 and track 1 are provided with, described hanger 2 runs along track 1; Also comprise and be arranged on bottom track 1, for the workpiece on described hanger 2 is processed chemical degreasing groove 3, ultrasonic oil removal groove 4, one-stage water wash groove 5, polishing trough 6, secondary washing bath 7, tertiary effluent washing trough 9, activated bath 10, between described secondary washing bath 7 and tertiary effluent washing trough 9, be provided with cathode electrolytic cell 8.After above-described hanger 2 mounts workpiece, hanger 2 is run along track 1, and process in the groove making workpiece immerse each processing step successively, after process completely, enter the plating of next electroplating work procedure.
