When picking or assembling different items that are not labelled, the problem of quality assurance for colours or shapes often arises. Is the picked or assembled part really correct? Support is provided by a picture selection.
The eyes principle
On a mobile, graphic display or on a permanently mounted assembly station PC, the employee is shown 4 different images from the database from LUCA-Server and designated as Pick-by-Picture . Depending on the objective of the inspection, different colours of the same product, shapes or different products are displayed. The selection and position of the images is random. Only one of the four images shown is correct. The remaining three pictures show small or bigger differences. The employee has to compare the product with the pictures and confirm it on the touch screen. If the confirmed image is correct, the process step continues accordingly. If the confirmation is incorrect or the employee cannot confirm an image, the process step is interrupted and the case is clarified. The end product can optionally be recorded as an image for later quality assurance.
Camera or eye?
Of course, automatic camera recognition for Pick-by-Picture® is a better alternative, depending on the product. However, the requirements for using a camera with image processing are not always easy to fulfil. The maintenance and servicing of such automatic camera systems with Pick-by-Picture® are also often very complex and expensive. LUCA can support both solutions with the Pick-by-Picture® method. We work here with well-known and professional camera manufacturers. Of course, the acquisition costs of the camera systems are significantly higher. We are happy to support you if required and often combine the method with other picking systems.
