Vision-Based Positioning and Laser Marking Production Line for Plastic Components
1. Definition
The Vision-Based Positioning and Laser Marking Production Line for Plastic Components is an automated system designed to perform high-precision laser marking on plastic parts. This line uses a vision positioning system to accurately identify the location and orientation of plastic components, and then employs a laser marking machine to engrave text, patterns, QR codes, and other information onto the surface of the parts. It is widely used in the manufacturing of plastic components for industries such as automotive parts, home appliance casings, and electronic product housings, significantly improving production efficiency and marking quality.
2. Main Components
- Conveying System: Utilizes belt conveying or vibratory bowl feeding to transport plastic components smoothly to the marking station.
- Vision Positioning System: Uses high-resolution cameras and advanced image processing algorithms to capture the position and orientation of plastic components in real time, providing precise positioning data for laser marking.
- Laser Marking Machine: The core equipment that performs marking on the plastic components based on the data provided by the vision positioning system. Different types of lasers, such as fiber lasers or CO₂ lasers, can be selected to meet various material and marking requirements.
- Marking Content Control System: Controls the marking content via computer or PLC, supporting dynamic data input such as serial numbers, production dates, QR codes, etc.
- Quality Inspection System: Uses vision detection or other sensor technologies to inspect the marked plastic components, ensuring that the marking content is clear and accurate.
- Finished Product Output System: Transports the marked plastic components to the next process or collection area.
3. Working Principle
- Component Feeding: Plastic components are placed on the conveyor belt either manually or through an automatic feeding device.
- Conveying and Positioning: The conveying system moves the plastic components to the working area of the vision positioning system, which captures the position and orientation of the components.
- Laser Marking: The laser marking machine performs marking on the plastic components based on the data provided by the vision positioning system.
- Quality Inspection: The inspection system checks the marked components. If any do not meet quality standards, they are automatically removed or an alarm is triggered.
- Finished Product Output: Qualified components are transported to the next process via the conveying system.
