According to relevant national regulations, the medical industry must indicate the product batch number, production date, and expiration date (or expiry date) on the packaging of drugs, which is commonly referred to as "drug phase three".
Nowadays, most of the three phases of pharmaceutical packaging on the market are stamped with steel characters, which are produced by character molds and have the advantages of not being easily worn and can be stored for a long time. Therefore, they are widely used in industrial production. However, due to the lack of significant contrast and color difference between the content of the stamped characters and the background color, it poses a huge challenge to traditional visual inspection of the quality of stamped characters. With consumers' increasing demand for product quality, if there are defects such as missing, vague, incomplete, or incorrect production dates and expiration dates, it will result in consumer complaints, damage to the company's brand, and other adverse effects.
Steel stamp character detection is an intelligent OCR detection system independently developed by Shanghai Botrong Electric Co., Ltd. The system adopts the latest AI detection algorithm. Compared to common traditional visual OCR detection solutions on the market, it has higher recognition rate, faster detection speed, stronger generalization ability, simple operation, and quick to get started. At the same time, with the help of Botrong's self-developed OCR intelligent labeling software, the system can be quickly adapted to new series of products. The steel stamp character detection system is applied in industries such as medicine, electronics, food and beverage.
