Optical quality control

Visual quality control is a process that uses visual inspection technologies to ensure that products or components meet required quality standards.

At KB Engineering, we value this type of quality control as it is non-destructive and already plays a crucial role in various industries including manufacturing, electronics, food, pharmaceutical, automotive and more.

In addition to optical quality control, we integrate other measuring and testing units such as weighing systems, ultrasound, sound testing, temperature measurement, moisture testing, etc. into our concepts.

Here are some important aspects of optical quality control:

    • Functions of optical quality control:
      • Defect Detection : Automatic detection of errors, defects, or irregularities in a product.
        Dimensional Inspection :  Verification of dimensions and tolerances to ensure that a product meets specified requirements.
      • Color detection: Identifying and monitoring colors to ensure they meet standards.
      • Surface Inspection: Examination of surface condition to identify scratches, dents, or other surface defects.
      • Code and Mark Reading :  Capture and verify barcodes, QR codes, or other markings.
    • Technologies in optical quality control:
        Camera systems: High-resolution cameras are used to capture images of products.
      • Image processing: Algorithms are used to analyze images, recognize patterns, and identify defects.
      • 3D image processing: In some applications, three-dimensional image processing is also used to obtain additional information.
    • Advantages of optical quality control:
      • Speed: The optical inspection can be carried out in real time.
        Accuracy: Automated systems can often detect minute defects that would be difficult for the human eye to see.
      • Consistency: The automated inspection ensures consistent quality without fluctuations.
      • Interval errors: By using intelligent control (AI), recurring errors, error frequencies or other algorithms can be identified more easily.
    • Application examples:
      • In the steel and forging industries to check components.
      • In the building materials industry for measuring and checking products and pallets.
      • In the food industry for inspection of packaging, products and pallets.

Optical quality control is an important tool for ensuring product quality, reducing costs and increasing efficiency in production.
