Is the tape on the black material checked with this visual sensor
Case study of Akusense vision sensor detecting the presence or absence of tape on black materials.During the production and processing process, products need to be packaged and sealed. Sometimes, products that have not yet been sealed may proceed to the next production stage, or the sealing tape on the equipment may have been used up and not detected in a timely manner, which affects production and work progress; For this reason, equipment manufacturers often use sensors to detect the presence or absence of product sealing tape.
On black products, the presence or absence of tape detection poses greater challenges to sensors; In this issue, Xiao Ming will share a case study of Akusense Vision Sensor detecting the presence or absence of tape on black materials~
Project requirements
Need to check for the presence of adhesive tape on the AB side of the black material
The A side is a smooth surface, and the B side is a frosted surface
Introduction to Testing Scheme
The VDS10 series visual sensor is used for detection. The detection principle is to highlight the feature area under camera imaging, and determine the presence or absence of tape by detecting the fitted straight line at the edge of the tape.
Installation structure diagram
Note: A black frosted background plate should be added behind the material, and there should be no scratches or dirt on the background plate as much as possible.
Imaging effect
✔ OK, there is tape on the B side
❌ NGB surface without tape
✔ OK, there is tape on the A side
❌ NGA surface without adhesive tape
