Description
Technical Field
The invention relates to the technical field of bar code recognition. And more particularly, to an automatic recognition apparatus and method for a express mail bar code.
Background
Bar code technology is an emerging technology integrating coding, printing, identification, data acquisition and processing on the basis of computer technology and information technology. Bar code technology is widely applied to the fields of business, book management, storage, post and telecommunications, traffic and industrial control and the like due to the advantages of quick, accurate and reliable identification, low cost and the like, and plays a great role in the increasingly rising application of the internet of things.
In the process of decoding the bar code, the bar code is usually scanned by a scanning device to obtain a reflected light signal, or the bar code is photographed by a photographing device to obtain a bar code image, and the reflected light signal or the bar code image is identified to obtain bar code information.
At present, with the rapid development of the express industry, the bar code technology is more and more widely applied to express item identification. Typically, the express items in the express stream are polyhedrons, such as boxes, bags, belts, etc., and the face sheets with one-dimensional or two-dimensional bar code information may be attached to any one face of the express items. When the traditional express mail is processed, the face of each express mail adhered with the face sheet needs to be found manually and aligned to the scanning equipment for bar code recognition, and the method is low in processing speed and recognition efficiency, needs a large amount of manual operation and is not beneficial to automatic express mail processing.
In order to increase the processing speed of the express, express automation equipment is generally adopted in the prior art to process the express. When using the courier automation device to process couriers, the bar code on each courier must be identified to operate according to the properties of the courier. The automatic processing of the express mail can automatically scan multiple surfaces (not the bottom surface) of the express mail, but when the bar code is positioned on the bottom surface of the express mail, the automatic processing of the express mail cannot be realized. To solve the above problems, three methods are generally adopted: firstly, when a express mail is transferred on a conveyor belt, the gesture of the express mail is manually adjusted so that a bar code is exposed at a position which can be scanned by an automatic bar code scanning device; secondly, reserving a gap on a conveyor belt and arranging a bar code scanning device below the gap when the express mail is transferred on the conveyor belt, and solving the scanning problem of the bar code positioned on the bottom surface of the express mail through the bar code scanning device arranged below the gap; thirdly, scanning all surfaces of the express item simultaneously through automatic six-surface scanning equipment.
The above treatment methods have the defects that: the gesture is manually adjusted, so that the processing speed is reduced, and a large amount of manual operation is required, so that automatic express processing is not facilitated; the gap below the conveyor belt is adopted for scanning, and a complete assembly line is required to be split into multiple sections, so that the cost of equipment is increased; the automated six-sided scanning is expensive and inconvenient to use in existing equipment.

the first recognition unit is single-sided bar code scanning equipment arranged in the opposite direction of the manipulator or single-sided bar code scanning equipment arranged on the same side of the manipulator and used for directly scanning the first surface of the express item to perform first bar code recognition;
The bar code reflecting device is arranged in the opposite direction of the manipulator, and the single-sided bar code scanning equipment arranged on the same side of the manipulator performs first bar code identification on the first side through the bar code reflecting device;
the automatic identification method of the automatic identification device comprises the following steps:
the manipulator grabs the express mail and exposes the first surface of the express mail;
performing first bar code identification on the first surface;
The manipulator takes the first surface as the bottom surface of the express mail to place the express mail on a conveyor belt;
judging whether the first bar code identification is finished, if not, carrying out second bar code identification on the non-bottom surface of the express mail through a second identification unit arranged above the conveyor belt.
2. The automatic identification device of claim 1 wherein the barcode reflecting means is a flat mirror.
3. The automatic identification device of claim 1, wherein the second identification unit is a five-sided barcode identification apparatus.
4. The automatic recognition device according to claim 1, wherein if the first barcode recognition is judged to be completed, a recognition result is generated and stored based on the first barcode recognition, and the automatic recognition of the express barcode is completed.
5. The automatic recognition method according to claim 4, wherein the first bar code recognition is judged to be completed, the second recognition unit continues to perform the second bar code recognition on the non-bottom surface of the express mail, and recognition results are generated and stored based on the first bar code recognition and the second bar code recognition to complete automatic recognition of the express mail bar code.
