With reference to fig. 4 and 7, the infeed station 2 is followed by the painting station 3.

The painting station 3 comprises a rotating mechanism 31 arranged on the frame 1 and a painting mechanism 32 for painting the opening edge of the motor shell 9.

The rotating mechanism 31 includes a rotating disk 311 and a rotating disk drive 312 for driving the rotating disk 311 to rotate. The surface of the frame 1 has a notch for mounting the rotary disk 311. The periphery of the rotary disk 311 extends upwards to form an annular rib to limit the circumferential escape of the motor casing 9, and the rotary disk drive 312 is a motor connected with the bottom of the rotary disk 311. The rotating disk lifting member 313 is connected to the bottom of the rotating disk driving member 312 for controlling the lifting thereof. The bottom of the machine frame 1 is also fixedly provided with a flat plate 314, the rotating disk driving element is an air cylinder vertically arranged on the flat plate 314, and a piston rod of the air cylinder is connected to the rotating disk driving element 312 so as to control the lifting of the rotating disk driving element 312.
