2) when the step 1) is carried out, a plastic part (2) is placed on a feeding station by a feeding mechanical arm (4), the plastic part (2) is clamped by a clamping jaw (7) on a plastic part shifting mechanical arm (6) and is moved to a water gap cutting station, a water gap (3) on the plastic part (2) is just positioned below a water gap cutting knife, the water gap cutting knife (42) descends under the driving of a cutting cylinder (41) and cuts the water gap (3) on the plastic part (2), and after the cutting is finished, the water gap cutting knife (42) ascends and resets;
3) after the water gap is cut, the plastic part (2) is moved to a film coating station by a plastic part moving manipulator (6), and the film cut in the step 1) is coated on the outer surface of the plastic part (2) by a film coating assembly; before coating, the film cut in the step 1) is positioned below the film-coated flexible ball (33), the lifting cylinder (27) drives the annular fixing plate (29) to descend, so that the cut film is just in contact with the uppermost end position of the plastic part (2), then the film-coated flexible ball (33) descends under the driving of the film-coated cylinder (34), the film-coated flexible ball (33) presses the plastic part (2) through the film, and the film is tightly attached to and coated on the outer surface of the plastic part by means of the deformation of the film-coated flexible ball; after the film coating is finished, the film coating flexible ball (33) is driven by the film coating cylinder (31) to ascend and reset;
4) the plastic part shifting manipulator (6) transfers the plastic part (2) after film coating to a blanking station, and finally the blanking work of the plastic part (2) is finished through the blanking manipulator (5);
5) and circulating the steps.
