UV Laser Marker with CCD and Conveyor for Batch Marking

What is a CCD Vision Positioning System?

A CCD vision positioning system is an advanced technology that utilizes industrial cameras (CCD cameras) for image capture and processing. It employs CCD cameras to capture real-time images of product surfaces, identifying feature points or contour information to achieve automatic positioning and feature point analysis of workpieces.

CCD vision positioning technology can be integrated with laser marking machines. By adding a high-precision CCD camera, it captures product images, and the real-time image data of one or more products is transmitted to the control system via a computer. The control system analyzes the image data to guide the laser for precise marking, enabling accurate marking without manual intervention or the need for fixtures. This system is suitable for batch processing of parts with various complex shapes and sizes.

CCD vision positioning technology is not only applicable to UV laser marking machines but also to CO2 laser marking machines and fiber laser marking machines. The vision positioning laser marking system can quickly achieve product positioning and mark multiple identical products simultaneously. It can be integrated with an automated conveyor system, where products are precisely positioned first. After positioning, the conveyor pauses for vision-based marking. Once marking is completed, the control system moves the conveyor to mark the next product, saving labor and improving production efficiency. By combining vision systems and laser marking technology, a fully automated production process can be achieved, reducing manual intervention, enhancing production efficiency, and ensuring product consistency.

The CCD vision positioning system supports one-click automatic calibration and automatic distortion correction, adapting to different product shapes and orientations. The visual recognition speed of a CCD vision positioning laser marking machine is extremely fast, capable of processing hundreds of parts per minute with low error rates. This effectively ensures marking quality, reduces errors caused by manual operations, saves manual loading time, meets the demands of mass production, and significantly improves production efficiency while lowering labor and production costs.

Working Principle of the CCD Vision Positioning System

The CCD vision positioning system uses a CCD camera to capture images of target objects, extracts feature points through image processing algorithms, and determines the position and orientation of the target object by combining matching algorithms. It can directly acquire a large amount of image information (up to 12 million pixels), overcoming the limitations of ultrasonic or infrared sensors and achieving higher precision in target positioning.

After real-time image capture by the CCD camera, the system automatically preprocesses the images (including noise removal, contrast enhancement, binarization, edge detection, etc.) to improve image quality and highlight feature points. Key feature points are then extracted using methods such as edge contour detection, and finally, the extracted feature points are matched with the preset marking positions in the system.

To eliminate the effects of lens distortion and improve positioning accuracy, the CCD vision positioning system requires camera calibration. Common calibration methods include: Faugeras calibration, Tsai's two-step method, Weng's iterative method, and self-calibration methods.
