[0043] See also Figure 2 In some embodiments, the first motion mechanism 110 includes a polished rod cable arranging device 1112, a reciprocating frame 1113, a spraying component 111 frame, a first rotating seal 161 and a first driving motor, and the first rotating seal can be a dynamic sealing flange; the first driving motor is used to drive the polished rod cable arranging device 1112 to reciprocate up and down on the reciprocating frame 1113, and the spraying component 111 frame is installed on the polished rod cable arranging device 1112.

[0045] In some embodiments, the workpiece 122 has a spherical surface, and the spraying member 111 is provided with an electrostatic gun head, which faces the spherical surface of the workpiece 122. During the coating process, the workpiece 122 rotates under the drive of the second motion mechanism 120, and the spraying member 111 reciprocates in the vertical direction, so that the paint sprayed by the spraying member 111 forms a trajectory curve on the surface of the helmet. Since the angular velocity of the second motion mechanism 120 and the reciprocating velocity of the first motion mechanism 110 can be set, the shape of the trajectory curve on the surface of the workpiece 122 can be determined, so that the spherical outer surface of the workpiece 122 can be sprayed evenly.

The distance between the workpiece 122 and the electrostatic gun head is greater than 250mm, which can prevent sparking.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
