With the development of laser coding technology, the laser coding has been widely used in medicine 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 environmental 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 work piece (a narrow damage zone);
4) High reproducibility, high speed and throughput;
5) Contamination - free.
|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 detect medicine box by photoelectric detection device, when the medicine box move to marking position, the marker will be triggered to do online marking. For non-uniform velocity moving product line, add speedometer to do speed compensation, then achieve variable speed laser coding.
