Presence and Completeness Check

Presence/completeness inspection checks at line speed that every element a product should carry is in place, of the right type and complete. The key to a reliable result is lighting and a station structure designed for the product: every element checked is lit so that it stands out clearly in the camera image.

At our inspection station for gel cards used in blood group typing, the gel and liquid levels in the tubes are measured one by one, the tubes are checked for particles, and the card's label and barcode are read and verified; a card that fails any check is sent to the reject line. The image on this page shows the particle and label check of an eight-tube card.

At our plastic part inspection station, the part's shape, the position and size of its front and rear notches and the grille area are checked, and a faulty part is separated before it reaches the next stage. In both applications results are saved with the images, and counts of good and faulty products and statistics by defect type are shown on the operator screen.
