CCD Vision Laser Marking System

Fiber Laser Marking Machine with CCD Vision Auto-Alignment

CCD Auto-Alignment Laser Marker

Product Overview

The Dowin Laser Marking System with CCD Camera is an advanced, automated marking solution that integrates high-precision machine vision with a high-speed fiber laser. Designed for demanding production environments, this system eliminates manual positioning errors and enables fully automated, batch marking of pre-fixtured or variably placed parts. It is the ideal choice for industries requiring strict traceability, zero-defect marking, and high throughput.

Core Function

The system automatically detects, locates, and aligns the laser marking path relative to the workpiece or a pre-existing feature (such as a hole, edge, or fiducial mark) using its integrated CCD camera. This ensures each mark is placed with micron-level repeatability, regardless of part placement consistency within the working field.

Key Features

1. Integrated High-Resolution CCD Camera: Captures a clear top-down image of the marking area in real-time for precise visual recognition and calculation.
2. Auto-Focus & Auto-Calibration: Automatically adjusts the focal plane and calibrates the coordinate system for each batch or part, ensuring consistent mark depth and clarity.
3. Intuitive Vision Software: User-friendly software allows easy teaching of marking templates. Users simply define the target area and reference points on the camera image.
4. Template Matching & Batch Processing: Stores multiple product templates. The system can recognize different parts and apply the correct marking program automatically, enabling mixed-batch production.
5. High-Speed Galvanometer Scanner: Coupled with a fiber laser source, it delivers fast, non-contact marking at speeds up to several thousand millimeters per second.
6. Robust Industrial Design: Built with a rigid mechanical structure and protective optics to ensure long-term stability in factory conditions.

Primary Advantages

• 100% Positioning Accuracy: Eliminates human error from manual alignment, guaranteeing every mark is in the exact specified location.
• Dramatically Increased Efficiency: Reduces setup and alignment time to near zero. Enables continuous processing of trays or fixtures of parts without operator intervention.
• Simplifies Fixturing: Eliminates the need for ultra-precise (and expensive) mechanical jigs. Tolerances are handled by the vision system.
• Enables Complex Applications: Perfect for marking on pre-machined parts, curved surfaces (with auto-focus), or around existing features where traditional methods fail.
• Reduces Scrap & Rework: Virtually eliminates mis-marked parts, saving material cost and protecting brand reputation.
• Seamless Integration: Can be easily integrated into automated production lines or robotic cells for Industry 4.0 smart manufacturing.

Target Applications

This system is critical for any application where mark position is as important as the mark quality itself:

• Electronics Manufacturing: Precise marking on PCBs, microchips, connectors, and sensors.
• Automotive & Aerospace: Traceability marking on engine components, turbine blades, and structural parts where placement is constrained.
• Medical Device Manufacturing: UDI (Unique Device Identification) compliance marking on surgical tools, implants, and instrument housings.
• Precision Engineering: Marking on machined components, tools, molds, and gauges.
• Consumer Goods: Accurate logo and serial number placement on high-value items like watches, jewelry, and luxury goods.

The Dowin Laser Marking System with CCD Camera transforms a standard laser marker into an intelligent, automated work cell. It represents the convergence of precision optics, robust laser technology, and advanced machine vision, delivering unparalleled accuracy, speed, and operational simplicity for modern manufacturing challenges. It is not just a marker; it is a quality assurance and productivity enhancement system.
