Abstract

The invention belongs to the technical field of additive manufacturing, and specifically provides an online detection method and system for the PCB production process of an intelligent production line, including step S1: collecting surface images of electronic devices on the intelligent production line under a multi-spectral lighting environment; S2: Perform defect detection on the surface image; S3: perform misjudgment and screening on the defect detection results; S4: import the final detection results after misjudgment and screening into the intelligent production line for feedback adjustment. Through the multi-spectral lighting environment, the uniformity of the surface illumination of the tested electronic product is significantly improved, thereby improving the accuracy of image recognition; by first using the deep network for defect detection, and then using the multi-physics model for misjudgment and screening, more reliable detection is obtained. result. Finally, according to the test results, the product is repaired or removed, and the loss is stopped in time, which improves the yield rate.

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 ...
