s03: needle brushing and grinding: the blind hole plate (5) is moved into the waste frame (31) through the conveying unit (1), then the conveying unit (1) is separated from the blind hole plate (5), the surface of the blind hole plate (5) is ground through the surface grinding unit (3), and the plate is taken again through the conveying unit (1) after the grinding is finished;
s04: washing with water: the blind hole plate (5) is moved to a water washing unit (4) through a conveying unit (1), the blind hole plate (5) is washed with water, and the plate is taken again through the conveying unit (1) after the washing is finished;
s05: drying: and continuously moving the blind hole plate (5) to one end of the conveying unit (1) through the conveying unit (1), taking down the blind hole plate (5), putting the blind hole plate into drying equipment for drying, and then performing the next process.
10. The method for removing adhesive residue on the surface of a press-fit blind hole plate as claimed in claim 9, wherein the step S02 of removing adhesive is performed, and the adhesive removing liquid is depleted to Mn7+Content (wt.)<When the concentration of Mn in the solution is 45g/L, a third linear mechanism (21) is started, the regeneration pool (23) is lowered, the degumming solution is transferred from the degumming pool (22) to the regeneration pool (23), the regeneration pipe (230) is electrified, and Mn in the solution is regenerated through the regeneration pipe (230)7+Mn of the solution in the regeneration tank (23)7+When the concentration of Mn in the Mn-Zn alloy is restored to 65g/L, a third linear mechanism (21) is started, a regeneration pool (23) is lifted, and Mn is regenerated7+The degumming liquid is transferred from the regeneration tank (23) to the degumming tank (22) to continue degumming.
