Intelligent code scanning equipment with automatic centering and angle segmentation functions

Abstract

The invention relates to an automatic centering and angle segmentation intelligent code scanning device, which comprises a centering conveying device, a rotary objective table, a code reading device and an industrial personal computer, and is characterized in that the centering conveying device is arranged in front of the rotary objective table, and the rotary objective table is arranged in front of the code reading device; the centering mechanism is driven by an air cylinder to enable centering push plates on the two sides to move relatively at the same speed to achieve automatic centering of goods, intermittent rotary motion is conducted through a cam divider, and the code reading device rapidly measures the distance between a code scanner and a two-dimensional code through a laser distance measuring sensor. The focal length of the code scanner can be automatically adjusted through front-and-back, up-and-down and left-and-right movement of the structure, so that the spatial position three-dimensional data of the code reader is corrected to read a high-quality two-dimensional code image, and the device has comprehensive functions, automatically adjusts the code scanning range, adapts to accurate, efficient and stable recognition of two-dimensional codes on packaging boxes of different sizes, and is high in practicability. The system is high in automation degree, wide in application scene and suitable for market promotion.

Description

technical field [0001] The invention relates to a code reading device used in the field of cargo management, in particular to an intelligent code scanning device for automatic centering and angle division. Background technique [0002] Two-dimensional code, also known as two-dimensional barcode, refers to a graphic that uses a specific geometric figure to be distributed on a plane (two-dimensional direction) according to a certain rule, black and white, and records data symbol information; The concepts of "0" and "1" bit streams that constitute the internal logic basis of the computer use several geometric shapes corresponding to the binary to represent text and numerical information, and automatically read through image input equipment or photoelectric scanning equipment to realize automatic information processing. It has some common features of barcode technology: each code system has its specific character set; each character occupies a certain width; it has a certain ver...

Problems solved by technology

[0004] At present, most of the existing code reading devices on the market can perform normal code reading work in a small range, and the flexibility of automatic correction is not high, and the efficiency is low. When the reading range is larger, in many cases, it is necessary to sacrifice a larger stroke in exchange for the range of the readable code; in the case of a large number of goods, the goods will often enter the scanning range at different angles, if the two-dimensional If the code is not directly facing the code scanning device, it will bring certain difficulties to the code scanning, and if it cannot be scanned accurately, it will affect the work efficiency. At this time, it is generally used to manually adjust the angle of the goods to help the code scanning device continue to work, but it takes up a lot of time. Manual, low degree of automation
