Barcode/QR Scanner

The Barcode/QR Scanner is a component used in chemical manufacturing environments, specifically within automated drum labeling and tracking systems. It employs laser or image-based technology to scan and decode barcode and QR code labels affixed to chemical drums. This enables automated data capture for inventory management, tracking drum contents, monitoring movement through facilities, and ensuring compliance with safety and regulatory requirements by linking physical drums to digital records.

The scanner operates by emitting a light source (laser or LED) onto the label. The reflected light pattern is captured by a photosensitive sensor, such as a CCD or CMOS in image-based models. The decoder analyzes the pattern—dark bars and light spaces for barcodes, or the matrix pattern for QR codes—and converts it into digital data. This data, including drum ID, chemical type, and batch number, is transmitted to the central database or control software for processing.

Key parameters include a scanning distance of 50–300 mm, a minimum resolution of 0.127 mm, a scan rate of 100–500 scans per second, and a reading angle tolerance of ±60 degrees. Operating temperature ranges from -20 to 50 °C, storage from -40 to 70 °C, and humidity from 5% to 95% non-condensing. The scanner offers ingress protection ratings of IP54 to IP65, operates on 5 V DC ±10% with power consumption of 1.5–2.5 W, and supports USB or RS-232 interfaces. Typical weight is 150–250 g, with dimensions of 170×70×110 mm.

Materials include an optical lens, image sensor (CCD/CMOS), LED or laser diode, plastic or polycarbonate housing, and electronic circuit board. These specifications are reference ranges; verify model-specific values and standards with the legal manufacturer or supplier before procurement.

The scanner emits a light source (laser or LED) onto the barcode/QR code label. The reflected light pattern is captured by a photosensitive sensor (like a CCD or CMOS in image-based scanners). The scanner's decoder analyzes the pattern of dark bars and light spaces (for barcodes) or the matrix pattern (for QR codes), converts it into digital data, and transmits this information (such as drum ID, chemical type, batch number) to the system's central database or control software for processing and tracking.
