Refrigerator gap measurement and logo inspection

Refrigerator gap measurement and logo inspection Project type: Automatisation Date 2021 In production at the customer, a system is required on the assembly line for checking the refrigerator logo & door gap. You want to implement a vision system with image processing control at the final quality inspection station. Requirements: 1) REVIEW OF THE DOOR PALT: On our assembly line, there is a probability of door errors of about 2%. A quality inspector at the final quality inspection station detects these errors and filters out these misaligned products. Our goal is to automate this process and implement an automatic inspection using a vision camera and image processing. - The tolerance for the door offset shall be <1,5 mm. LOGO/MONOGRAM INSPECTION: Two errors can occur with logos. 1) Logo misaligned 2 logo damaged 3) Logo not available For these three defects, we have to perform the inspection with the same image processing system that is also used for door gap control. Missing Signs, Missing and Damaged Signs A separate camera/sensor can be used for checking the logo. All characters of the logo must be recognized with OCR and the orientation must also be checked. Other details: - The cycle time must be <2 seconds for the door gap test and logo check. - Fixed assembly line barcode reader to be included in the system for reading the barcode of the product automatically and selects the recipe.
