LDPE Film Machine Vision Inspection
Problem Phenomenon
Manual quality inspection has a high miss rate; after introducing online vision, the defect recognition rate reaches 99.5%.
Cause Analysis
Tiny defects such as pinholes and gel particles are difficult for the human eye to capture continuously; online machine vision can perform full-width real-time inspection and record defect positions.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience.
Solution
①Configure an online vision inspection system; ②Establish defect classification standards; ③Link with process parameters for traceability; ④Calibrate the system regularly.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Key Takeaway
Online inspection is the direction of quality upgrading; data accumulation can also feed back into process optimization.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
