step nine: when the cleaning balls 8 pass through the electrophoresis cell 19, the discharging telescopic rod 14 extends, the dried workpiece 16 is immersed in the electrophoresis cell 19 for electrophoresis, the discharging telescopic rod 14 is shortened after the electrophoresis is finished, and the ball taking conveying belt 12 leaves the electrophoresis cell 19.
Finally, the workpiece 16 and the floating block 9 are all taken out of the sphere 81, so that the workpiece after electrophoresis is obtained, and the sphere 81 and the cover 82 can be reused.
The electrophoresis working platform and the method in the embodiment carry out efficient and all-around cleaning on the dirty workpieces before electrophoresis so as to reach the electrophoresis standard of the surfaces of the workpieces, save the step of carrying out multiple times of cleaning on the dirty workpieces independently, improve the electrophoresis efficiency, realize continuous automatic cleaning on the workpieces in batches and provide guarantee for continuous electrophoresis.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
