Based on the traditional marking machine, the product is first polished to ensure clear appearance, and then a template is made and saved. Then, a high-precision CCD camera is used to locate the current position of the product, and one or more products collected in real-time are visually positioned to calculate the XY coordinates and deflection angles of the products. The product position information is transmitted to the marking card through the computer in sequence, thereby achieving precise marking. The appearance of products processed by visual laser marking machines can be recognized as circular, square, or irregular shapes. This process is particularly suitable for small products and eliminates the need for positioning trays and fixed fixtures, greatly saving the laser marking processing cycle. It is also suitable for online laser marking processing when moving assembly line products.

Application scenarios:

Electronic manufacturing industry:

Semiconductor chip: Mark the traceability QR code in a 0.5mm ² area (resistant to high temperature etching);

Precision circuit board: Engrave micrometer level markings next to curved solder joints to avoid damaging components.

Medical and Food:

Drug packaging: Spray the batch number on the surface of the curved medicine bottle and wipe it with alcohol resistance;

Food tank: Real time marking of production date on dynamic assembly line (speed ≥ 30m/min).

Hardware accessories:

Batch processing of screws, buckles, and other small items, with automatic identification and labeling for over 50 items placed at once.

Maintenance and troubleshooting:

Pattern distortion: Clean the focusing lens, calibrate the mirror offset;

Localization failure: Update feature template, adjust light source brightness;

Daily maintenance: Wipe the lens with anhydrous ethanol and check the vacuum adsorption pipeline.
