Label and Code Inspection

Reliably Recognizing Codes and Labels

With the image processing systems from senswork, codes and labels can be reliably recognized, read out and checked for correctness. Curved or reflective surfaces are also no problem for our camera systems.

Reading and verification of 2D and 1D codes in manufacturing

Scanning Bar Codes

For traceability and identification purposes, 2D codes are now applied to products and components using a wide variety of methods such as laser marking/ labeling, needling or printing. This is generally referred to as DPM (Direct Part Marking). In order to guarantee the quality and legibility of 2D barcodes in particular, there are different standards such as AIM/DPM or ISO/IEC, which in some cases define different quality characteristics for the assessment of codes. AIM/DPM aims for directly marked bar-codes, while ISO/IEC 15415 covers printed 2D Codes.

Bar-code scanners by Cognex distinguish themselves with a high flexibility, a simple set-up and an easy installation and are the perfect solution, even for very sophisticated fields of application in the industry. The robust, high-performance, portable bar-code scanners are the perfect solution for the toughest manufacturing and logistic environments.

Bar Code Verification

The image-based bar-code scanners by Cognex and Microscan enable us to offer you a fully configured camera solution to scan, verify and validate 2D codes at your production site. A bar-code check can be defined as the process to rate the quality of 1D, 2D and DPM codes (Direct Part Mark).

An increasing number of regulated industries request a verification of bar-codes. In this context, verification is a detailed check of the code quality against a defined standard, which is often carried out offline with a camera and lighting set-up defined by a standard committee.

The bar-code verification devices by Cognex use high-value optics, cutting-edge algorithms and simple software to proof conformity with the industry standards. The validation systems makes it possible to rate the quality of directly marked codes during high-speed productions and errors or deviating quality features in the labeling can be detected in due time.
