Correct placement check for TVs and home appliances
As the open carton passes under a top-view camera, product position, corner foams and accessories are verified region by region in a single image. A carton with a missing or shifted item is diverted to a side lane before sealing.
Region results and product offset are stored with the carton ID; a carton with a missing item is pushed onto the side lane and re-checked once completed. The result is shown region by region on the operator display.

Need
Foam, the dark product surface and kraft board sit together inside the carton; the accessory box and the foam can share the same light tone. The carton arrives a few centimetres off-centre on the belt, and the open flaps can cover the edge of the image.
Solution approach
The camera on the gantry looks straight down at the carton; bar lights on both sides reduce shadows and a photo-sensor triggers the strobe. A reference is first found on the carton edge; product, four corner foams and accessory regions are then verified in turn against that reference, and the offset of the product centre from the carton centre is measured.
Process steps
- 01
Infeed
The open carton enters the station and the photo-sensor triggers the camera.
- 02
Acquire
The bar lights strobe and a top view of the carton contents is captured.
- 03
Placement
Product, corner foams and accessory regions are verified one after another and the product offset is measured.
- 04
Decide
If all regions pass the carton goes to sealing; otherwise it is diverted.
