Visual inspection solutions are an indispensable component of modern industrial automation. Integrating optical, mechanical, electronic, and computer technologies, they enable rapid and accurate quality control of products. A comprehensive visual inspection solution typically comprises the following core elements:

1. Light Source System: Provides stable, uniform illumination to ensure clear visibility of surface features on inspected objects. Various light source types, such as LEDs and halogen lamps, are available and should be selected based on inspection requirements.

2. Lens and Camera: The lens focuses light to form a clear image, while the camera captures the image and converts it into digital signals for subsequent processing. Selection should consider parameters like resolution, frame rate, and sensitivity.

3. Image Processing Software: The core component analyzes images through algorithms to extract features and determine product compliance. The software must possess robust image processing capabilities and flexible programming interfaces.

4. Mechanical Structure and Drive System: Responsible for positioning, transporting, and securing workpieces to ensure stability and repeatability throughout the inspection process.

Example: PCB Component Missing Detection Solution

Plan Components:

1. Light Source: Utilizes a coaxial light source to minimize reflections and enhance component contour clarity.

2. Lens and Camera: Employs high-magnification lenses and high-speed industrial cameras to capture minute components.

3. Image Processing: Identifies missing components by comparing reference images with captured images through template matching algorithms.

Advantages: Rapid inspection speed, capable of processing hundreds of items per minute; high accuracy, minimizing misjudgments; ability to record inspection data for easy traceability and analysis; high automation level, reducing manual intervention and enhancing overall production line efficiency and stability.
