Automatic positioning and code reading device with rotary objective table

Abstract

The invention provides an automatic positioning code reading device with a rotary objective table, which comprises the rotary objective table, a code reading device and an industrial personal computer, and is characterized in that the rotary objective table is arranged in front of the code reading device, and the rotary objective table and the code reading device are respectively connected with the industrial personal computer; intermittent rotary motion is performed through the cam indexer, the output segmentation precision is high, the high-speed performance is good, cargoes can be effectively and accurately braked under the cooperation of the first brake and the brake roller, when the two-dimensional codes of the cargoes are read, the distance between the code scanner and the two-dimensional codes is rapidly measured through the laser distance measuring sensor, and the accuracy of the two-dimensional codes of the cargoes is improved. And the focal length of the code scanner can be automatically adjusted through the movement of the front-back, up-down and left-right structures, so that the warehousing of goods and the updating of information are accelerated, and the code reading efficiency is greatly improved. 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 automatic positioning code reading device with a rotating object stage. Background technique [0002] At present, the logistics industry is developing rapidly with the prosperity of online shopping, and the requirements for the management level of cargo storage are gradually increasing. Now most of the goods will be marked by pasting identification codes such as QR codes, and identified and classified by reading the identification codes. goods. When the laser sensor is working, it can emit a beam of laser light to the detection target. After the laser reaches the detection target, it is reflected and scattered in all directions. Part of the scattered light can return to the receiver of the sensor. The time of receiving the reflected laser light can calculate the distance from the detection target. [0003] At present, most of the existing code re...

AI Technical Summary

Problems solved by technology

[0003] 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 a larger reading range is required, a large sacrifice is required in many cases. In exchange for the range of readable codes; when there are many goods, the goods will often enter the scanning range from different angles. If the two-dimensional code is not facing the scanning equipment, it will bring certain problems Difficulty, the inability to scan accurately will affect the work efficiency. At this time, the method of manually adjusting the angle of the goods is generally used to help the scanning equipment continue to work, but it takes a lot of labor and the degree of automation is low.
