Classification: CPC B  G  Y | IPC B

Claim 2:
3. The automatic press-fit control method according to claim 1, wherein in the step 4, the inspection process comprises:
step A: controlling an industrial camera to take photographs of the workpiece, and controlling an image processing system to process and analyze images of the photographs, to extract positions of axial holes from the images through edge detection, and to compare the extracted positions and shapes of the axial holes with positions and shapes of calibrated circular holes in order to determine whether the positions of the axial holes are deviated, wherein step B is executed if the positions are deviated, and step D is executed if a hole deviation angle is within an adjustment range;
step B: sending, by the visual inspection subsystem, a detect-pass signal to the control center, thus completing the inspection process;
step C: sending, by the visual inspection system, the hole deviation angle to a turntable motor driver, wherein the turntable motor driver is driven to rotate by one compensating deviation angle, and repeating the step A; and
step D: calculating, by the image processing system, the hole deviation angle, and sending, by the visual inspection system, a detect-fail signal to the control center if the hole deviation angle exceeds a preset upper limit of deviation compensation, thus completing the inspection process.
