[0025] S1. Loading, placing the O-ring mold with the O-ring inside on the fixed seat in the fixed tooling, and positioning the positioning pin through the positioning hole on the O-ring mold to ensure that the O-ring mold is stably placed;

[0026] S2, limit fixation, start the motor, drive the driven transmission wheel to rotate through the active transmission wheel and the transmission belt, the driven transmission wheel drives the driving rod and the gear to rotate, and the gear and the rack are meshed to make the rack drive the limit fixture to move relatively, and the limit fixture moves to the top of the O-ring mold to position it, ensuring that the O-ring mold will not move during the inspection process;

[0027] S3, move to the detection position, the dual-axis motor drives the rotating rod and the moving wheel to rotate, the moving wheel rotates on the top of the slide rail to drive the motor seat, the flip frame and the fixed seat to move horizontally, and move the O-ring mold to the side opposite to the detection mechanism and the positioning mechanism.

[0029] S5, flipping. When the upper end surface inspection is completed, the first cylinder drives the first lifting frame to move upward, and the second cylinder drives the second lifting frame to move downward. The first stepper motor drives the flip frame to rotate, driving the fixed tooling to flip 180 degrees, so that the other side of the O-ring mold faces upward, and the other side of the O-ring is inspected for defects. After the flipping is completed, the first lifting frame and the second lifting frame are reset;
