s4, when the ascending distance of the trigger plate (71) reaches a second threshold value, the upper closing plate (73) removes the blockage of the partition plate (4), meanwhile, the T-shaped blocking rod (97) ascends under the pushing of the trigger plate (71), and then the blockage of the second valve (96) is removed from the interior of the hollow shaft (62), and at the moment, the clarified mixed solution passes through a channel on the partition plate (4) and falls onto the top of the filter plate (5) to be filtered by the filter plate (5);

s5, after the second valves (96) are unblocked, the air pump (94) inputs air flow inside the brightener storage tank (91) through the air inlet pipe (93) to push the brightener inside the brightener storage tank (91), the brightener enters the hollow shaft (62) through the discharge pipe (95), is sprayed out through the second valves (96) and is mixed with a mixed solution to be filtered to form a copper plating solution;

s6, when the rising distance of the trigger plate (71) reaches a third threshold value, the mixed solution at the top of the partition plate (4) completely passes through a channel on the partition plate (4) and falls into the top of the filter plate (5), the lower closing plate (75) is driven by the connecting rod (74) to block the channel on the partition plate (4) from below, then the driving motor (63) is stopped, the brightener continuously enters a cavity formed between the partition plate (4) and the filter plate (5) through a second valve (96), and the partition plate (4) is closed, so that the mixed solution rapidly passes through the filter plate (5) due to pressure and falls into the electroplating bath (2) under the condition that the pressure between the partition plate (4) and the filter plate (5) is enhanced until the copper plating solution is transferred;

s7, pre-plating copper on the workpiece by adopting a conventional alkaline copper plating process, and then putting the pre-plated copper workpiece into a plating bath containing a copper plating solution for electroplating treatment.
