When picking or assembling different items that are not marked, the problem of quality assurance for colors or shapes often arises. Is the picked or assembled part really correct? Support is provided by an image selection.
The eye 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 goal of the inspection, different colors of the same product, shapes or different products are displayed. The selection and position of the images is random. Only one image out of the four displayed is correct. The remaining three pictures show small or bigger differences. The employee must compare the product with the images and confirm it on the touchscreen. If the confirmed image is correct, the process step is advanced 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 subsequent 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 meet. Also the maintenance and servicing of such automatic camera systems with Pick-by-Picture® are 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.
