7. The management method according to claim 6, wherein the step (3) comprises the sub-steps of:
(3.1) adjusting an image processing algorithm of a line body server in the AOI server, carrying out defect detection on a product by the line body server according to a product image in a line body image storage bank, comparing a defect detection result with a detection result of an AOI defect detection station, and judging whether over-detection and missing-detection exist or not; if no over-detection and no missing detection exist, entering the step (4); if the over-detection or the omission detection exists, the step (3.2) is carried out;
(3.2) generating a defect report containing information of the defect position and the defect type of the product according to the over-inspected or the missed-inspected product image, and uploading and storing the over-inspected or missed-inspected product image to a remote AOI server;
(3.3) adjusting an image processing algorithm of a remote AOI server in the AOI server, carrying out defect detection on the product by the remote AOI server according to the stored product image, and comparing the defect detection result with the defect report in the step (3.2) to judge whether over-detection and missing detection exist;
and (3.4) repeating the step (3.3) until no overdetection or omission occurs.
8. The management method according to claim 7, wherein the step (2) further comprises the steps of: and uploading the result of the pre-detection to an AOI defect detection work station, and automatically comparing the defect detection result with the result of the pre-detection by the AOI defect detection work station so as to judge whether the over-detection and the omission detection exist.
9. The management method according to claim 8, wherein in step (3.2), the product images are sorted according to product category, production line, station and defect type and then stored in a remote image repository of the remote AOI server.
10. The management method according to claim 9, further comprising the steps that the remote AOI server sends the AOI software version to be updated to the wire body server, and the AOI software version of each AOI defect detection station is updated synchronously through the wire body server.
