With the development of laser coding technology, the laser coding has been widely used in medical industry, such as marking patch number, production date, date of expiry, anti-fake code on medicine box, medicine bottle, capsule, and label etc.
1) Non-contact marking and no special working environment required;
2) Easy to automate and integrate (direct writing of patterns can establish using computer-controlled movement of the beam or sample);
3) Precise beam positioning and a beam highly localized energy transfer to the workpiece (a narrow damaged zone);
4) High reproducibility, high speed, and throughput;
|Medicine box||Electronic supervision code||Blister pack||Medicine bags|
|Capsule||Label||Medicine bottle||Metal Box|
The laser coding was finished on customer’s product line, that is the laser coding system was directly installed onto customer’s semi-automatic or full-automatic product line. The laser coding system detects medicine box by a photoelectric detection device, when the medicine box moved to marking position, the marker will be triggered to do online marking. For non-uniform velocity moving product line, add a speedometer to do speed compensation, then achieved variable speed laser coding.
|Application||Colored medicine box||Capsule|

|Max. marking speed||45 m/min||25m/min|
|Max. Output/hour||About 11000 boxes||About 60000|
|Coding time interval||≤1ms||≤1ms|
|Percent of pass||≥ 99.9%||≥ 99.9%|
