How to Detect Mask Defects

How to Detect Mask Defects

Oct 20 2020

Machine vision inspection instead of manual, not only saves labor costs, but also high speed, accuracy, repeatability, long-term work stability, the application of machine vision technology in the mask defect detection can largely improve product quality and production speed.

Using masks as an example, Wordop can detect defects in machine vision to detect features such as mask breathing valve, front/back distinction, dirt, hair, ear band length/offset, nose bar length/offset, etc.

Breathing valve - positive and negative differentiation test

Aluminum bars with or without testing 

Dirt-hair detection

External contour inspection, stitch positioning inspection

Check if the ear band cord of the mask is properly pressed
