Abstract

The invention belongs to the technical field of additive manufacturing, and particularly provides an online detection method and system for a PCB production process of an intelligent production line,and the method comprises the steps: S1, collecting a surface image of an electronic device on the intelligent production line in a multispectral illumination environment; s2, performing defect detection on the surface image; s3, misjudging and discriminating a defect detection result; and S4, importing a final detection result after misjudgment and discrimination into the intelligent production line for feedback regulation. The surface illumination uniformity of the tested electronic product is remarkably improved through the multispectral illumination environment, and then the image recognition accuracy is improved; defect detection is carried out by using a deep network, and misjudgment and discrimination are carried out by using a multi-physical-field model, so that a more reliable detection result is obtained. Finally, the product is repaired or removed according to the detection result, damage is stopped in time, and the yield is increased.

Description

technical field [0001] The invention belongs to the technical field of machine vision detection, and in particular relates to an online detection method and system for the PCB production process of an intelligent production line. Background technique [0002] Printed circuit board PCB (printed circuit board), referred to as printed board, is one of the important components of the electronics industry. Printed boards are used in almost every electronic device that has electronic components such as integrated circuits. However, due to the complex manufacturing environment of more and more PCBs and the large number of process steps, there are more and more defects (such as warping, delamination, cracks, short circuits, etc.). Therefore, the importance of defect detection in the printed circuit board manufacturing process is also increasing. Therefore, the importance of defect detection in the printed circuit board manufacturing process is also increasing. At present, manual ...
