[0040] Based on the background art, an automatic optical inspection system is usually applied to a production line to detect defects of workpieces. To ensure the normal detection ability of the automatic optical inspection system, it is usually necessary to test the detection ability of the automatic optical inspection system before the production line runs. Currently, the detection results of each automatic optical inspection system are usually recorded manually, and then based on the detection results, it is judged whether the detection ability of the automatic optical inspection is normal.

[0071] In this embodiment, the preset duration can be 2 hours.

[0072] In this embodiment, blocking the production line 30 means suspending the use of the production line 30 where the automatic optical detection system 20 that is continuously determined to have an abnormal detection performance within the preset duration is located, facilitating relevant technical personnel to view the abnormal situation, and timely maintaining and updating the automatic optical detection system 20. In addition, it also prevents production errors from occurring if production continues subsequently.
