Device and method for acquiring product coded identifier information

Abstract

The invention relates to a device and a method for acquiring product coded identifier information. The device comprises a data acquisition unit, a data identification unit and a control unit, wherein the data acquisition unit is positioned above a convey belt and comprises an image device, a lighting device and a position photoelectric switch; the image device is used for photographing product coded identifier to obtain image data; the lighting device is used for irradiating the product coded identifier; the position photoelectric switch is used for sensing the position of the product on the convey belt; the data identification unit is used for identifying and processing the image data acquired by the data acquisition unit to obtain the product coded identifier information and storing theinformation and is also connected with the image device and the control unit respectively through a data line; and the control unit is used for controlling the data acquisition unit, and connected with the data identification unit, the image device, the lighting device and the position photoelectric switch respectively through data lines. The invention also provides the method for acquiring the product coded identifier information.

Description

technical field [0001] The present invention relates to a product data collection device and method, in particular to a product coding identification information collection device and method. Background technique [0002] At present, general products on the market use digital codes or barcodes (one-dimensional codes, two-dimensional codes) to identify product-related information (such as production date, shelf life, manufacturer, etc.), and fast production line codes often use digital codes to identify individual product information. , barcodes are used relatively sparingly. [0003] The means and methods of the existing production line to track product information are mostly pre-associated, that is, before the product is packed, the information system has set in advance the individual product information and the small packing box identification information (including the information of each product scheduled in the packing box). ), the association relationship between the ...

Problems solved by technology

[0006] The post-correlation method can form an accurate correlation between product information and packing information, but the current post-correlation product identification information collection method is not ideal. Generally, ordinary cameras are used to take pictures of product digital codes or barcodes. Product identification information, before transferring imaging data to a computer for processing

At present, the inkjet inks used for product labeling information on the market are all ordinary inks, which can basically meet the purpose of marking information, but for camera imaging, ordinary inks have no special light-sensing effect. Imaging is susceptible to product packaging background color and environmental interference, and the product identification recognition rate cannot meet market demand, resulting in large image color interference, difficult identification, or even unrecognizable situations, which brings greater difficulty to the collection of product identification information. not effectively
