Automatic identification device and method for bar codes of express items

Abstract

The invention discloses an automatic identification device and method for bar codes of express items. The device comprises a mechanical arm, a first identification unit, a judgement unit and a secondidentification unit. The automatic identification method applied to the device comprises the steps that the mechanical arm grabs the express items and exposes first surfaces of the express items; thefirst surfaces are subjected to first bar code identification; with the first surfaces as the bottom surfaces of the express items, the express items are placed on a conveying belt through the mechanical arm; whether or not first bar code identification is completed is judged, and if not, the non-bottom surfaces of the express items are subjected to second bar code identification through multi-surface bar code scanning equipment arranged above the conveying belt. According to the automatic identification device, the bottom surfaces and the non-bottom surfaces of the express items are distinguished, based on a two-step identification process, the problem is solved that the bottom surfaces of the express items on the conveying belt cannot be quickly and conveniently identified, the device iseasily applied to existing automatic identification equipment and is low in transformation cost, high in identification speed and high in automatic degree, and the automatic identification process for the bar codes of the express items is optimized.

Description

technical field [0001] The invention relates to the technical field of barcode identification. More specifically, it relates to an automatic identification device and method for express barcodes. Background technique [0002] Bar code technology is an emerging technology developed on the basis of computer technology and information technology that integrates coding, printing, identification, data collection and processing. Barcode technology is widely used in business, library management, warehousing, post and telecommunications, transportation and industrial control due to its advantages of fast, accurate, reliable and low-cost identification, and is bound to play an important role in the emerging Internet of Things applications . [0003] In the process of decoding barcodes, scanning equipment is usually used to scan barcodes to obtain reflected light signals, or to use photography equipment to photograph barcodes to obtain barcode images, and to identify and process ref...

Problems solved by technology

[0006] The above processing methods all have their disadvantages: manually adjusting the posture reduces the processing speed, and requires a lot of manual operations, which is not conducive to automated express processing; using the gap under the conveyor belt for scanning requires splitting the complete assembly line into multiple sections to improve reduce the cost of the equipment; adopt automatic six-sided scanning, the equipment is expensive, and it is not easy to apply to the existing equipment
