To meet cycle times typical for supply-side automotive manufacturing, this 3D inspection station integrates a microcontroller, multiple cameras, and image management software. As a result, it checks every surface of a molded-rubber, shock-absorber oil seal in less than 4 sec.
Three Omron F150-3 cameras constitute the inspection system's first station. A conveyor delivers the seals on rotating platens. Each camera photographs the seal 12 times as it rotates in 30 degrees steps. Then, a pneumatic transfer mechanism inverts the seal onto another 12-step rotating platen. A fourth F150-3 inspects the underside.
Pattern matching and surface defect analysis algorithms, part of OMRON's "Vision Composer" image management software, give the seals a go/no go pass as they are carried away by a second conveyor.

Station one inspects the seal lip, main body and seal side. Station two looks underneath. Image management software coordinates the four cameras and Omron CPM1 microcontroller. |
