BUMPY BAR CODES Zero Contract Readers
Represented by highs and lows in surface height rather than changes in black and white as found in traditional bar codes, Bumpy Bar Codes are indented, peened, cast, etched, stamped, molded or embossed directly into parts or tags, representing serial or part numbers. Bumpy Bar Codes permit work in process (WIP) data collection, traceability and error proofing in environments in which black and white bar coding techniques are ineffective.
Implementing a Bumpy Bar Code system enables permanent product traceability while reducing manufacturing costs and scrap rates. Bumpy Bar Codes provide a competitive edge allowing companies to meet increasingly stringent quality standards such as ISO and QS-9000.
BUMPY BAR CODE READERS - FIXED MOUNT
Housed in a rugged Nema 4 enclosure, the fixed mount reader is designed for harsh industrial environments. It can withstand high temperatures, high humidity, wind blown dust, and being hosed down with water. Reading is controlled by relays or PLCs and decoded Bumpy Bar Code data is communicated to the local data system via an RS-232, RS-422, or RS-423 interface.
An adjustable swivel mounting bracket eases installation, allowing effortless alignment of the reader on the target. The fixed mount reader also provides a maintenance port for setting the reader parameters and downloading new software and firmware.
BUMPY BAR CODE READERS - HANDHELD READERS
The Bumpy Bar Code product line consists of 510, 1010, and 1410 readers, each tailored for applications based on product material, width and depth of bar code, marking and read range requirements. Bumpy Bar Code Readers are built with durable components for reliable applications in both manufacturing and field environments. All units read traditional black and white linear bar code symbologies, as well as three-dimensional Bumpy Bar Codes.
How Does it Work?
Bumpy Bar Code Readers work by illuminating the bar code target with a laser and capturing the reflected image in a two-dimensional CCD (the same technology used to capture images in a video camera). The angular displacement between the laser and CCD array provide the basis for the detection of the differences in height across the Bumpy Bar Code.
Once captured by the CCD array, the reflected image is digitized and processed by an onboard Digital Signal Processor (DSP) chip. The DSP chip computes the heights of the bars and spaces and then decodes them against any linear symbology.
