[AI Image Inspection Case] Counting the Number of Circuit Boards
We will measure the number of overlapping circuit boards using AI image inspection software!
When measuring the number of circuit boards handled by an electronic component manufacturer while they are stacked with interleaving paper, we aimed to reduce the time spent on manual work and eliminate measurement errors by incorporating image recognition. 【Inspection Setup and Results】 To measure 52 circuit boards, we read images using EI-Scan, improved the image accuracy, and utilized the "Luminance Change Inspection" feature of EasyInspector. First, we conducted verification with the interleaving paper pattern, and by neatly aligning the gray interleaving paper with the brown circuit boards, we were able to accurately count the number of boards. Next, we also verified the pattern without interleaving paper, and since shadows were created between each board, we were able to count them accurately as well. Furthermore, by scanning at a 30-degree angle, we were able to detect chips of about 0.2mm. 【Software and Equipment Used】 Software Used: EasyInspector310 Field of View: 70mm (thickness when stacking 52 circuit boards) Minimum Size of Inspection Target: Approximately 10mm Number of Inspection Points: 52 Images: Images read using EI-Scan For counting the number of boards, 'EasyNumbers' is recommended.
