What is a Visual Positioning Laser Marking Machine?
The visual positioning laser marker is a device that combines vision positioning technology with laser marking technology. It utilizes a computer vision system to real-time recognize and locate objects, and then marks and engraves on the object surface using a laser beam. The vision positioning system captures images of the target object, processes them through image processing and algorithms to recognize and locate the object’s position. The control system receives this position information and calculates the motion trajectory of the laser beam, controlling the scanning system to accurately mark and engrave on the object’s surface, ultimately meeting high-precision positioning and marking requirements.
How Does CCD Vision Laser Marking Machine Works?
The CCD vision laser marking system realizes efficient and accurate marking of products by integrating vision positioning technology. The core lies in templating and storing the product features as a standard reference. In the actual processing, the CCD camera captures the product image and compares it with the pre-stored template, and the computer quickly completes the position identification and calibration, thus guiding the laser head to carry out accurate marking. This process is not limited by the shape of the product, whether it is round, square or complex irregular shapes can be recognized and processed. Laser marking machine with CCD visual positioning is particularly suitable for small parts, as cumbersome positioning fixtures are no longer required, thus significantly reducing laser marking preparation time and overall processing cycle time.
Flying Online Laser Marking Machine with CCD Visual Automatic Positioning
Visual positioning laser marking machine can often be combined with flying marking equipment to form customized laser marking solutions. These machines integrate a CCD vision system with dynamic on the fly marking technology to automatically recognize the position of the target object and perform accurate laser marking on high-speed conveyor assembly lines.
Vision positioning ensures that the laser can accurately mark in a preset pattern even when there is a slight change in product position, which is particularly useful for high-volume, continuous production lines that require high-precision marking. For example, in industries such as electronic components, food packaging, and automotive parts, fast-moving products need to be marked with high quality and consistency in a short period of time.
Vision positioning systems are widely used in various types of laser marking machines, including fiber laser marking machines, UV laser marking machines and CO2 laser marking machines, which enhance the automation and flexibility of various types of equipment, and combined with the high speed flying fiber laser marking machine, help to achieve a more efficient and accurate modern production line.

2. Scanning System: scanning system consists of scanning mirrors and scanning drivers, used to control the laser beam in the two-dimensional plane movement. Scanning system can make the laser beam on the surface of the target object for fast and accurate positioning and movement.
3. Visual positioning system: visual positioning system using a camera or other image acquisition equipment to obtain the image data of the object. Through image processing and computer vision algorithms, it can recognize and locate objects in real time and provide accurate location information.
4. Control System: the control system is the core part of the visual positioning laser marking machine, it receives the position information provided by the visual positioning system, and controls the laser source and scanning system to carry out the corresponding operation. The control system is usually composed of a computer and the corresponding control software, which can be used for parameter setting, marking pattern and marking process control.
