Laser Marking Machine for Assembly Line
Detailed Description in English:
The laser marking machine for assembly line is a specialized device designed for automated production lines, enabling the batch automation of product marking. It typically comes in two forms: one is a standalone machine equipped with a sliding platform for the assembly line below; the other integrates the laser head into an automated production device to form a fully automatic laser marking assembly line. This machine can be equipped with different types of lasers, such as fiber lasers or UV lasers, depending on the material and application. It is widely used in various industries, including electronics, hardware, plastics, and metal processing, to mark products with high precision for text, graphics, QR codes, etc.
The laser marking machine for assembly line has several advantages, including high efficiency, non-toxicity, no pollution, and exquisite marking effects. It operates fully automatically with computer panel control, using a laser to directly mark characters on products without the need to replace ink cartridges, reducing maintenance costs. Additionally, the machine is equipped with a vision system to achieve automatic positioning and imaging, improving the accuracy and efficiency of marking.

Operation and Maintenance of Laser Marking Machine for Assembly Line
I. Operation Procedures
- Preparation
- Material Preparation: Choose materials that are compatible with the laser and ensure the material surface is clean, flat, and smooth.
- Connecting and Powering On the Machine: Connect the laser marking machine to the power supply and computer, and verify that all connections (such as the laser head, CCD camera, etc.) are normal. Turn on the power and check if the equipment is working properly.
- Software Installation and Configuration: Download and install the software that accompanies the vision-based laser marking machine from the official website. Register and set parameters such as font, size, and color.
- Vision Positioning and Engraving Setup
- Image Acquisition and Processing: Use the CCD camera to capture a clear image of the object to be marked. Ensure the camera lens is clean and the focus is accurate. Use matching software such as Vision Pro or Machine Vision Studio for pre-processing to make the target position recognition more accurate.
- Object Recognition and Coordinate Generation: The software automatically or manually identifies the target position in the image and generates marking coordinates.
- Print Template Creation: Edit the label and import it into the software. Adjust the image parameters of the light source, such as brightness, contrast, and exposure time. Place the edited marking content at the desired position on the image of the product to be marked, and complete the creation of the vision marking template.
- Print Parameter Settings: Set the power, speed, focal position, and other parameters of the laser marking machine in the software according to the recognition results and specific requirements.
- Printing Process
- Vision Positioning and Adjustment: Adjust the machine’s position through vision positioning settings to ensure the accuracy of the marking.
- Start Printing: Place the content to be marked at the designated position, click the “Start” button in the software, and the laser marking machine will begin the printing process according to the preset path and parameters.
- Monitoring and Feedback: Monitor the printing effect in real-time during the process. If there are any deviations or unexpected situations, make adjustments through the software.
- Post-processing
- Printing Completion: After printing, turn off the laser source and save the printing records.
- Inspection and Cleaning: Check the quality and clarity of the marking, and clean the equipment and work area to avoid residual materials affecting the next printing effect.
II. Maintenance and Care
- Daily Maintenance
- Clean the Equipment: After each use, clean the worktable, monitor, and keyboard surfaces with a clean cloth, and remove any debris, especially metal residues or powders left after marking.
- Inspect Optical Components: Regularly clean the laser and lens to prevent dust and dirt from affecting the marking effect.
- Check Cooling System: Ensure the cooling water system is working properly, with appropriate water levels and good water quality. Replace the coolant regularly.
- Inspect Moving Parts: Lubricate moving parts (such as guides and gears) to keep them operating smoothly.
- Periodic Maintenance
- Replace Consumables: Replace consumables such as marking heads and filters in a timely manner based on the usage of the equipment.
- Calibrate the Equipment: Regularly calibrate the focal length and marking position of the equipment to ensure accurate marking.
- Upgrade Software: Regularly update the software version of the equipment to maintain its performance and functionality.
- Safety Precautions
